Twilight Sparkle dragged herself toward Carousel Boutique with her head hung down, exhausted, watching the dust on the road dance and swirl under the cold touch of the wind that had a tendency to ramp up drastically at this time of year. It wasn’t the perfect weather to walk around the town by any definition, but it was the perfect weather to shut yourself in the comforts of the castle’s laboratory and simply enjoy the process of unraveling the world’s mysteries. Today Twilight should have focused on studying Dr. Foalreud’s social theory on sibling bonding and friendship. She should have. And yet she had made no progress on the subject at all since morning.

For a moment the thought of turning her back to the boutique and running home flashed across Twilight’s mind. After all, it was Rarity’s fault that she had spent the entire day gathering dust on her coat while dating a colt.

But he is so charming, and you two have so much in common. It would be a crime to not give him a chance, darling. Twilight remembered Rarity’s words as she finally became tired of the taste of tulips in her mouth. She spat the flowers out into a nearby trash can and quickened her pace toward the boutique.

As much as Twilight wanted to continue her study, she could no longer postpone the fitting of her birthday gala dress. Unlike the previous year, this time the most important ponies from all over Equestria was going to rush into her castle, stomping one another on their way to her hooves for a ghost of a chance to say ‘Happy Birthday’ to the Princess of Friendship. She needed that dress badly and only the possibility of failing to meet Princess Celestia’s expectations for her as a representative of Equestrian Nation set her teeth to chattering.

Lost in her thoughts, Twilight hadn’t noticed that she was standing in front of Carousel Boutique, knocking on the door. A mere moment passed and Rarity emerged from the doorway with the speed that would put both Rainbow Dash and Pinkie Pie to shame. It was almost as if the fashionista were on the other side of the door the whole time, lying in wait.

“Twilight!” Rarity greeted with a warm smile spreading across her face. “Didn’t expect you to come so early. Come in, darling. I just so happened to have made tea and you’ll oblige me greatly if you accompany me. I’m dying to hear how everything went with Comet Tail.” The fashionista gave Twilight a sly glance. “In detail.”

Twilight let out an annoyed sigh, rolling her eyes. “Rarity, I’m thankful for your hospitality,” she said, her tone saturated with impatience. “But I am really, really behind schedule.”

“Oh no no no, darling. You aren’t going anywhere until you tell me everything.” Rarity wrapped a hoof around Twilight’s shoulder and led the way into the drawing room. The mare poured two cups of tea, loaded a plate full of cookies and set Twilight on a cushion at the table.

“I’m all ears,” Rarity said, taking a diminutive sip from her cup.

Twilight’s face pulled into a creased grimace as if the fashionista asked her to narrate something extremely inappropriate. For example, what kind of dildo she used to get off the last time or how was her personal life progressing for that matter. Rarity certainly didn’t have the right to pry her mouth open given Twilight had clearly stated that it was her own business. She gave up quickly, however. She knew that it would be much faster to indulge Rarity in a bit of gossip than to start an argument that she would most likely lose anyway.

“There’s nothing to tell, really,” Twilight began in an emotionless tone. “We ate some sandwiches at the restaurant, then he took me to the observatory. After that, we walked along the park for about an hour. In the end, he offered to meet up another time. I said no. End of story.”

“You did what?” Rarity gawked, dropping her cup from her telekinetic field and sending it back onto the table with a thump, brown stains spreading quickly across the tablecloth as the splashes of the liquid began to sink in. “I can’t believe it. He was an ideal stallion for you.”

Twilight just shrugged at that, sipping tea from her cup. “I told you it was a bad idea. I would have been better off working on my project today.” And yet, despite her grumpiness, a shred of a smile managed to sneak into Twilight’s features. “Though I must admit I enjoyed the observatory quite a bit.”

“So what went wrong? Was he being rude to you?”

“Rarity, please.” Twilight sighed. “He was really nice to me and I enjoyed his company. He told me a lot about stars that I didn’t know.”

Rarity raised her brow skeptically, struggling to believe that somepony might know about scientific stuff more than Twilight herself. “So what happened?” Rarity’s impatience grew.

“As I said, it wasn’t that bad. Comet Tail is a nice pony. It’s just...” Twilight paused, looking through the window at the blue sky musingly. “I think given enough time, I could make good friends with him.”

“Friends?” Rarity’s back sagged and her face paled as if Twilight’s words were a magic spell that had sucked out her vitality. “I think you take your status of the Princess of Friendship a bit too seriously, Twilight. It took me some effort to convince him to go out with you, to persuade him that your relationships had a chance to progress, that he was something more than just another umpteenth friend of yours. And now you’re telling me that you’re not giving him a chance despite how good your date went? I didn’t want to bring it up but do you know what nickname you earned after your first months in Ponyville? The Princess of Friendzone!” Rarity’s gibberish turned into hysterical laughter by that moment. “Nopony got surprised when Celestia bestowed an actual title upon you. The Princess of Friendship. Quite ironic, isn’t it?”

Yes it is, Twilight thought. Over the years that she had spent her life in Ponyville many a stallion tried to win her heart, and even quite a few mares. Needless to say, every one of them had been forced out of Twilight’s personal space and straight into her friend zone, offhandedly and without any explanation. One of those ponies, Rainbow Dash, dug her hooves into Twilight’s friend zone deeper than anypony else could ever risk of. But even such a determined and stubborn a pony like Rainbow Dash eventually gave up after a month of fruitless attempts. The pegasus more than once brought up a theory that Twilight was simply asexual. Rarity, however, refused to believe it and convinced herself that Twilight was just waiting for her knight in shining armor to sweep her off of her hooves.

Now, while observing Rarity’s stiff demeanor, it was hard for Twilight not to think that Rarity’s illusions had finally shuttered and that the fashionista had given up on her just like the rest of her friends. It will make things so much easier for me. Twilight’s joy was short-lived, however.

It didn’t take long for Rarity to gather herself up and, judging by the determined expression on the fashionista’s face, she was desperate enough to resort to her trump card before at last having to acknowledge her defeat and admit that Twilight’s case was completely lost.

“You can’t be married to your job, Twilight,” Rarity began slowly. “Even I, despite all the stress that’s pressing down on my back while managing three boutiques at once, find time to relax and enjoy my life. Time flies fast and before you know it, you’ll find yourself an old maid remembering old days and sorrowing for opportunities gone by. Do you really want to waste the best years of your life on books, Twilight?”

“Not the worst fate if you ask me.” Twilight shrugged. She turned her head to the window again and continued to stare at the sky, her mind floating among fluffy clouds. Books help a lot to distract my mind from him. And that’s more than enough.

“You know what? Forget it. It’s your life and if you’ve decided to die alone, who am I to stop you? Just your best friend who you refuse to open your heart to.” Rarity let out a puff of air.

Twilight inclined forward and gave Rarity a big hug to the fashionista’s great surprise. “I know that you’re just trying to help me, but this aspect of my life… I can figure it out on my own, I promise. Besides, I’m never going to be alone. I have you and the girls I can always rely on.”

“Well, of course you have us but...” Rarity shook her head. “I can feel that something’s bothering you even though you pretend that everything is just fine.”

“I guess I’m just a bookworm.” Twilight smiled. You won’t be able to help me anyway.

“Fine. I’ll leave you alone to your nerdy stuff.” Rarity got up from the table and walked over to the sink to wash her cup. “For a while,” she added.

“Fair deal then,” Twilight mumbled through a mouthful of cookies. She gulped it down with a swig of tea and got up from the table as well. “My admirers can wait until the gala. Right now I need a dress, and a good one.”

“Of course, darling. I can assure you, you’re going to outshine everyone there. Quite literally. I’ve prepared special gleaming gems for just this occasion. All I need is to take your measurements and I can start working on my greatest creation yet.”

The two mares walked up onto the second floor and made their way into Rarity’s workshop. Luckily for Twilight, the fashionista was much faster at doing her job than receiving her guests and before long Twilight’s list of things that needed to be done before the gala sported another red check mark.

“You’ve grown up quite a bit since your last measurement,” Rarity mused, putting the measuring tape back in its place. She gave Twilight a sly smirk. “Especially in your flanks. Somepony has been eating too many cakes of late.”

“I know, I know,” Twilight said, blushing. “This ‘princess growth spurt’ needs a lot of calories to maintain. I guess I’ve overdone it a little.”

“You know, Comet Tail likes them plump. Maybe you’ll change your mind and give him another chance?”

“Rarity!”

“Just joking. But seriously, you better stop with so many sweets. I know you would like to emulate Princess Celestia in every detail but I have only so many special gems to afford to make you a new dress each month.”

“I got it already!” Twilight’s face was one big blushing spot at the moment. “I’ll let Spike know to revise my diet. Do you need anything else from me or can I go home already?”

“You are free like a bird, darling. I won’t keep you any longer.” Rarity took a step closer and hugged Twilight goodbye. “Say hello to the girls for me. With all this work here it’ll take a while before I can hope to see them.”

“I will,” Twilight said as she made for the exit. “And thank you, Rarity. For everything.”

Luna had raised the moon high in the sky by the time Twilight returned to her castle. And though she hadn’t done anything productive the whole day, the date and everything that had followed it had left Twilight in such an exhausted state of mind that it felt as if she had just finished writing an encyclopedia on every single plant that could be found in Equestria. No, Twilight amended herself. The encyclopedia wasn’t that fatiguing.

Walking by the kitchen, the scent of stewed carrots stopped Twilight in her tracks. She made to step in but thought better of it. She stood there for a short while, breathing the savory taste in, then decided to skip her dinner and instead proceed to the study room. Not that she was feeling hungry anyway.

She made her way onto the second floor as an amorphous mass of ribbons, cushions, curtains, and Celestia knows what else emerged from the corner and hurried up to glide in her direction. She barely made it in time to pin herself against the wall, avoiding a collision and allowing the pile to fly by. A quick glance back revealed the purple butt of a pony who stood behind the floating abomination.

“Hi, Starlight,” Twilight said as she detached herself from the wall. “Where are you going with all this stuff? I thought we had everything we needed.”

“Oh, hello Twilight. Didn’t notice you.” Starlight stopped in her track, casting the mass down onto the floor and turning to face her mentor, a weary look on her face. “The Sheik of Saddle Arabia eventually decided to attend your birthday gala.” Starlight let out a heavy sigh. “With all of his retinue.”

Twilight raised an eyebrow at that. “How many?”

“Fifty ponies.” Starlight moved a hoof up to scratch the back of her ear, smiling weakly. “Minimum. I’m so sorry, Twilight. I know I promised that I’ll have everything prepared in time but I guess I messed up this time too.” Starlight winced as if preparing for Twilight’s outburst of panic and incoherent mumble at the ruined gala, but opened her eyes wide after a few seconds, observing Twilight’s serene demeanor.

Starlight put on a quizzical look, scratching her neck. “What? No running around in circles, crying out that you disappointed Celestia’s expectations and your life as a princess is over? You seem quite, well, I don’t know... Composed?”

Twilight gave her student a somewhat guilty smile. “I in no way mean to diminish your help but I’ve prepared a backup plan just in case if anything goes wrong. And I guess it happens to be just that. I have ponies that worked on Celestia’s gala waiting for my command. They’ll make sure that everything stays as close to the standards of a royal gala as possible. And I’ve already prepared the spell that will allow two halls to merge into a big one. Everypony would have plenty of space, food and other things, whatever they might be. I hope you’re not mad at me, Starlight?”

“Of course not.” Starlight giggled nervously. “Truth be told I’m glad to hear that somepony will get some weight off my back. Arranging a princess birthday turned out to be more exhausting than I could ever think of. Scrolling through countless guest letters has already earned me quite a headache. Not to mention learning all those titles, ranks and whose ass is more important as to be sitting in the front row and not in the second one. I don’t even know how you find the strength to finish everything in time. Especially considering you’re a princess and all that.”

Twilight grinned wide, showing a row of her white teeth. “Nothing special, really. Just countless years of practice of organization, scheduling, and scientific risk assessment.” She leaned in closer to Starlight. “But if you want a bit of wisdom, my faithful student, the main rule here is to change your activity from time to time when you get stuck. Let your brain have a little rest while you’re working on another task. Then, when you return your attention to the task at hoof, your vision of what’s needed to be done next will be more clear and thus your whole day will be more productive.”

Starlight’s face split with a mischievous smirk as she looked up at Twilight. “So that’s how you locals call a roll in the hay with a colt here in Ponyville. Change of activity you say.” Starlight’s naughty smile only grew more so. “What was his name again? Comet Trail?”

“Comet Tail,” Twilight amended, then fell silent, her cheeks a big spot of red. “I didn’t mean that kind of activity.” She leaned back from Starlight and turned aside to face the wall, a plain flat piece of crystal block and much more pleasant conversational partner at that. “How... How do you even know about him?”

“You know how.”

Twilight’s brow twitched, her gaze almost drilling a hole through the wall. “I swear, one day I’m going to kill Rarity. Whatever she told you, there was nothing between us. Nothing.”

“That’s good.” Starlight sounded pleased.

“Mm? That’s it? No lectures on how I have a heart of ice?” Twilight turned back to examine her student.

“Nope.” Starlight shook her head rapidly. “Don’t want my favorite mentor to be stolen away by some freaky colt. I love the nerdy Twilight, and this way you’re all mine, with more than enough time to help me to fit in Ponyville society and teach me a lot about friendship.”

“You know that selfishness is a bad characteristic for a friend, right?” Twilight jabbed Starlight’s side playfully.

“Is it? I guess we haven’t covered this topic yet.” Starlight let out a snicker.

Twilight supported her student with a chuckle of her own. “Remind me to add this subject to your curriculum.” She stretched a hoof out, yawning. “All right, I got to go. Have a lot of nerdy stuff to do.” Twilight looked down at the pile of miscellaneous things by Starlight’s hooves, then gave her student a supportive look. “Good luck to sort out this mess here.”

“Yeah. I’ll do my best. Good luck with your studies too. Hope to get a chance to help you when I get free here.”

Twilight nodded, then turned around and cantered off to her study room. By the time she reached her destination, her steady gait had turned into a gallop and she almost smashed the door off its hinges as she rammed herself into it.

The clock clanged midnight, shaking Twilight from her mindless staring at the pages of the book before her. She had made a lot of progress in the last few hours of her rigorous studying and almost caught up with the schedule she had planned out a week earlier. But by now her thoughts strayed away from the subject matter completely and even though she was trying to concentrate her mind on the book, it was as if she were staring at a transparent glass surface. Instead of seeing the words, she was looking past them.

Enough for today. Twilight got up from the table, ignoring a puddle of viscous liquid left on the chair. She would take care of it tomorrow. Right now she had much more important things to attend to. The deep research on sibling bonding she had just performed left her with the pressure pent up deep inside her that threatened to burst free any moment, and she’d been already struggling enough to hold it in place during the day. After all, she was not in the least indifferent to ponies, or more precisely, one white stallion, despite what Rainbow Dash might assume about her.

The first thing that Twilight did after walking into her room was to make sure the door had its heavy brass bar wedged firmly into the groove. Having done that, all that remained was to ensure that nopony could get in. She concentrated her mind on the protective spell she’d cast so many times before that the magic from her horn surged out almost effortlessly as if it were mere sparks of telekinesis, despite the intricate nature of the conjuration that would fatigue even the most powerful of unicorns. Waves of violet light rushed in all directions from Twilight, clinging to the walls, ceiling, and floor until the crystal room became a cage of a pulsating purple essence, harder than diamond, its molecular structure preventing any magic from slipping in and any sound from escaping out.

Twilight extinguished her horn with a satisfied smirk and stretched out, pushing her ass up into the air and allowing herself to truly relax for the first time since morning. Her pussy winked, bringing up a droplet of her juices that glided down her clit until it reached the bottom of her vulva and, with nothing to cling to, dripped down onto the sparkling floor. Twilight did her best to ignore the tickling sensation between her hind legs and began to slowly walk toward the bed, her tail swinging to and fro seemingly on its own.

Smiling like a naughty filly, she climbed onto the bed and crawled along on her belly to the other side until her muzzle was mere inches away from the nightstand, a complex piece of furniture with sturdy crystal frames and a set of magic locks installed in it. With a flicker and spark from her horn, the locks gave in and the only drawer box slid its way out of the nightstand. Twilight’s heart filled with excitement as the box’s content came into her view. And though she’d observed the object inside the box so many times that she could recall every little detail of it should she be awoken in the middle of the night, the experience was always enthralling and each time felt as if it were the first time in her life.

“Hello, brother,” Twilight whispered, leaning in to take the replica of Shining Armor’s cock into her hooves, a stars and shield Cutie Mark etched in its base. The whole thing was as huge and gorgeous as she’d seen it in the flesh, years back when she and Shining Armor shared the same home in Canterlot. The events of one particular night always arose in her mind whenever she took it – her brother running his hooves up and down along the length of his shaft, confident that the door to his room was closed and nopony could see him, his eyes squeezed at the impending surge of pleasure. And Twilight, sprawled out in the hallway, peeking in through the ajar door, her left hoof stuffed in her mouth to stifle moans of delight as her right hoof found its place between her hind legs, her pussy spasming and clutching at the intruder, her eyes fixed on Shining Armor’s throbbing cock, making her mind believe that it was her brother who was fucking her and not her own hoof.

She let out a pitched squeak into her hoof, almost revealing herself as her brother’s cock made the last powerful throb and a jet of cum burst out of his tip, painting a high white arc in the air and landing down onto his chest and belly. Something snapped inside Twilight then and a whole new set of sensations surged through her body, her clit spasming vigorously and her juices squirting out onto her tail and butthole as the feeling of pure bliss overwhelmed her whole being. She had read about sex and orgasm before of course – the entire castle library had been at her disposal since she’d become Celestia’s personal student. But she could have never imagined that orgasm might feel so good, so right despite the fact that the stallion she was clopping to was her own brother.

Bringing herself back from the long-past events to the present time, Twilight brought the artificial phallus to her lips and planted a kiss on the flat tip. She couldn’t live by memories alone, however beautiful and sweet. Her mind and body demanded a more material approach.

“I’ve missed you so much, big brother.” Twilight began to glide her hooves over the flare, gauging its shape and feeling every bump and ridge encircling the tip. She moved down along the phallus' length and squeezed it slightly, making the frogs of her hooves rub against every little vein along the shaft, the curves as close to the original as possible.

It had cost her a fortune to make a replica of her brother’s cock so accurate. More than that, it’d taken her a long while to polish it to perfection, the only possibility of having inside her anything different from her brother’s form making her stomach clench. She hadn’t had the luxury to get a real imprint of Shining Armor’s erection and a scatter of glimpses had been all she had to work with. Many nights had been spent to solve that puzzle and place all the pieces of the mosaic in her mind’s eye into the final, total picture in real life. But in the end, the result had exceeded all expectations and her brother’s cock had served her well for many years, and this night wasn’t going to be an exception.

“I’m sorry I couldn’t come earlier. There was a lot of work to do today.” Twilight brushed the medial ring and continued down to stroke the balls, a part of the implement she’d been racking her brain with for the longest time. She had to re-study the anatomy book to make the balls look and feel like a part of a real stallion. Unlike a manufactured model which had two hemisphere pieces of plastic simply glued to the base of the cock, the ballsack of Twilight’s creation hung off the shaft and had its own creases where it was connected to the sheath, as well as a pair of special egg-shaped implants imitating the curvature of testicles. And yet despite its complexity, the whole structure paled beside the synthetic skin that covered the whole thing and that had become the apex of Twilight’s craft genius.

“I know how I can make up for my delay, big brother.” Twilight assumed a sultry look as she opened her mouth wide, her tongue trailing a loop over her lips before it stretched away in the direction of her chin, providing an unhindered way to her mouth. Not wasting a second, Twilight threw her head back and slid the wide tip of the artificial cock along her tongue until she had it prodding at the entrance of her throat. Suppressing the urge to gag, Twilight wrapped her right hoof around the base of the cock and pushed in hard with one thrust, her throat contracting and stretching around the girth with a wet gurgling sound as the first beads of tears began to accumulate in her eyes.

Twilight ignored her body’s earnest protests at a foreign object cutting off its supply of oxygen and pushed the cock in further still. She choked hard as the medial ring stretched her throat even further, her instincts almost making her hoof pull the cock out. She managed to collect herself, however, and drove the cock deeper, making the last inches of the whole length disappear inside her completely with only the balls jutting out from the warmness of her mouth and instead pushing down against her snout, their enormousness preventing the air from getting into her nostrils as successfully as the shaft wedged in her throat blocked every breath Twilight’s body tried to draw despite her better judgment.

With her brother’s cock sculpting the outline of her neck, Twilight took a few seconds to accommodate to her position. Despite how many times she’d practiced deepthroating with her brother’s cock, Shining Armor was a very endowed stallion and Twilight’s tight orifice could only take him for so long. Twilight knew that she hadn’t that much time left before she would begin to suffocate.

Twilight took her hooves away from the cock, put them down on the bed and straightened her forelegs along her body. She did her best to relax, her brother’s cock still buried deep inside her throat. She closed her eyes and slowed the inner working of her body, preserving as much of precious oxygen in her lungs as possible. Then, in a state similar to that of pure serenity, her horn lit up and the cock in her throat began to move back and forth under the influence of her magic.

In her mind, Twilight conjured up the images of her brother, trying to bring up the most intimate moments they’d been through together – reading a good book at night while cuddling each other under the blankets, all the while their parents thinking that their kids had long ago fallen asleep. Or the time when she’d failed Celestia’s test and been bawling her eyes out into her cushion until her brother had sat next to her, patting her head. He’d always known what to say and how to comfort her when she felt bad, even when her parents failed at that. But more often than not, Twilight would just get nostalgic about carefree times whether it was she and Shining playing hide-and-seek in the courtyard or splashing water at each other in the bath when they were foals. Whatever memory sprung in Twilight’s mind eye, it had never crossed the line of sibling attachment and yet it was always more than enough to evoke the most primal desires deep inside her core when lying in bed alone at night.

With one powerful thrust Twilight’s magic slammed her brother’s cock back deep into her spasming throat, the impulse so sudden as to make her eyes water. Twilight didn’t complain and allowed her brother to use her as he wished so – rough and without any constraints, ethical or otherwise, with nopony to judge their deep bond.

Moaning around the cock, Twilight felt the heat between her legs rise to a blaze, her pussy squirting a spray of her juices onto the bed. Not breaking the spell that moved the cock up and down her throat, Twilight dragged a hoof down along her thighs and placed it on her drenched pussy. She began to rapidly stroke over her outer lips, moving to rub her swollen clit every time it showed up from under her labia.

But no matter how good she felt with her brother’s cock buried deep inside her, eventually biology took a toll and Twilight began to feel dizzy, then suffocate badly as her body had spent the last morsels of oxygen stored in her lungs. She enjoyed the last moments of her brother’s girth as much as she could before jerking the cock up completely in one pull, the flared tip brushing her from inside all the way from the depths of her throat to her lips until it popped from her mouth with a loud wet noise. As soon as there was nothing to cram her narrow orifice, a sharp cough overtook Twilight and she was forced to roll over onto her belly. Choking and gasping for air, Twilight finally made that needy breath that her body had so long demanded and allowed the oxygen to fill her burning lungs, a trail of drool leaking from her mouth unceremoniously. She panted heavily for a while, then levitated a towel from a nearby wardrobe and wiped the excess saliva off her face, as well as a couple of tears that had managed to escape her eyes before her throat had a chance to get used to the foreign object inside it.

Twilight threw the towel aside and turned to look at the artificial cock that was lying peacefully beside her. She couldn’t help but smile at the results of her work as she admired its slippery surface that was fully covered in her saliva, from the tip down to the base where a small puddle of her oral fluids accumulated on the two massive orbs. It seemed incredible now that there had been a time when she could barely take a quarter of her brother’s cock without throwing her dinner up before gagging to near unconsciousness.

“Did you like it, BBBFF?” Twilight was sure he did. If there was one truth that she’d learned from scores of books on how to please your stallion, it was that it’s easier to find a vegan manticore than a stallion who wouldn’t be head over heels in love with a mare who can perform a perfect deepthroat. And Twilight wasn’t known to be a mare who would ever stop until she’d brought all things to perfection.

“Now it’s your turn to please me.” Twilight giggled flirtatiously. She hugged the cushion before her and raised her ass high in the air, her tail flicking from side to side in excitement, revealing her winking pussy with the beads of sparkling moisture trickling down her thighs.

“Please don’t make me wait, Shiny.” She waved her rear back and forth, whining slightly. “I won’t be able to fall asleep tonight without your thick cock having pounded me.”

Twilight buried her face in the cushion as her mind conjured up the images of Shining Armor tenderly biting her nape, then going up to nip at her ear, his warm breath wrapping around her neck and cheek. He slid closer to her and Twilight felt the weight of his masculine forelegs press on her back, pushing her deeper into the bed. Her horn sparked and she let out a low moan as his cock brushed against her swollen outer lips. Shining flicked up her clit and began to travel up and down along her tight slit, teasing Twilight to her great frustration. She bit down on her upper lip as the heat inside her became every bit unbearable, all her thoughts focused on having her brother spreading her wide and pushing deep inside her.

As if sensing that his little sister was on the verge of collapse without his cock, Shining thrust forward, shoving the whole length of his stallionhood to the hilt inside her. Twilight instantly reacted at the contact and enfolded Shining’s cock in the sopping warmth, changing the shape of her pussy to perfectly match the curve of the cock, hugging it so tightly as if it had always belonged inside her.

“Yes!” Twilight cried into the cushion, her body trembling at an immediate wave of pleasure that surged through her. “I love you so much, Shiny. Please don’t stop thrusting.”

Encouraged by Twilight’s words, Shining slid his cock out a few inches before shoving himself in again, his balls slapping against Twilight’s ass as he bottomed inside her. After another powerful thrust that almost sent Twilight tumbling forward, he fell to a steady rhythm, moving inside his sister with rapid speed and turning Twilight into a trembling mess.

Twilight had to make every effort to keep her rear up, her pussy spasming around the cock, trying to hold her brother in as long as possible, wrapping it perfectly with no resistance at all.

“Yes, it feels so good,” Twilight managed between moans. She hesitated for a mere moment before deciding to recite some obscene phrases she’d learned from one particular smutty book before. “My pussy is being ravaged by my brother’s thick cock. Ahhhh. You’re so big, Shiny. Please fuck my tight pussy harder. I can’t live without your cock inside me.” Though there was nopony in the bedroom but Twilight, the words had left a big blush on Twilight’s cheeks even so.

Everything that she knew about sex was from either anatomy textbooks or shabby romance novels, as Rarity would put it. And almost in every such a novel, a stallion would like his mare to behave herself like a slut and worship his masculinity while in bed. Twilight hardly imagined her chivalrous brother would like such promiscuous behavior, but it wasn’t like she ever had a chance to spy on his and Cadance’s sexy night times to prove otherwise. So the only choice that seemed to make any sense was to cling to books – the only source of wisdom that never failed her – and hope that she hit the mark or at least landed it nearby. Not that she knew any better herself.

“Oh, Shiny, your cock is tearing me apart,” Twilight continued to moan as another strong thrust sent her face first into her pillow. “My pussy is spasming around your cock so tightly. Please use my pussy as a living fleshlight. Don’t ever stop thrusting.”

Shining didn’t seem to have a mind to stop and if anything simply complied, thrusting himself into Twilight with the relentless force of a beast breeding his bitch. Twilight winced at a jolt of pain running up her spine after an especially powerful thrust that almost penetrated her cervix but other than that gave away no sign of discomfort and only encouraged her brother to move even faster. She was so close to orgasm as to risk to slow down even a little. Besides, she was her brother’s bitch that he could do anything with as he wished.

A high shriek of pleasure broke free from Twilight’s throat as her and her brother’s union reached its apex. For a moment anxiety overwhelmed Twilight that her moans were loud enough to penetrate the protective spell around the room, but the fear of getting caught disappeared as quickly as it arrived and was replaced with a feeling of pure bliss circling through her body.

Twilight tightened her pussy around the cock with a vice-like grip, not wishing the feeling of complete fullness to ever leave her. Her hind legs buckled under her trembling body, sending her ass to drop onto the bed. As Twilight fell, more and more of her juices kept squirting from the tiny gaps between the cock and her pussy, turning the surface of white linen sheets under her rear into scores of viscous transparent pools emanating strong mare scent.

Her pussy dripping, Twilight lay motionless in her bed for a long while, riding post orgasmic waves with the cock still jammed deep inside her, the ballsack bumping against Twilight’s thighs every time her hind leg twitched at an unexpected jolt of pleasure. Even after the last traces of Twilight’s orgasm dwindled to nothing, she wasn’t in a hurry to gather herself from a sprawled mess of delighted unconcern. She was so happy being with Shiny, connected to him, feeling the bond that only two ponies loving each other could have. It felt so wrong to break that bond. And yet she couldn’t fall asleep with her brother’s cock buried in her pussy. The protective spell encircling the walls of her room was too delicate to maintain during sleep and if anypony, or for that matter any dragon or worse still some intrusive draconequus, found out about her feelings to her brother... Well, Twilight didn’t want to think about it. That’s why she took every precaution to protect her little secret, the secret that she would take with her to her grave.

Stretching her limbs, Twilight finally gathered enough strength to flip herself on her back. She shot a glance between her legs to admire how well she fitted her brother’s cock and what an ideal pair they were, then extended a hoof to grab the base of the cock. She began to withdraw it out slowly inch by inch, wincing as the cock’s length rubbed inside her oversensitive pussy and scraped at her still winking clit. With a sigh, Twilight pulled out the last inches of the cock from her pussy, then brought the tip up to her muzzle. An abundance of her juices dribbled off down onto her chest as she sniffed the sour fragrance in.

“Thank you, Shiny. You’re the best brother a pony can have.” Twilight assumed an impish smile. “I don’t know what I would have done without you.” She trailed her eyes over the whole length of the cock attentively as if she were afraid that she would never see her brother again, her juices sparkling, catching the violet light of the aura that surrounded the room. “Just give me a second, I need to clean you up before we turn in. We don’t want Cadance to know that you have more fun with your little sister than you do with your wife.” Twilight giggled at her own quip.

Opening her mouth wide, Twilight stuck her tongue out and traced its wide surface over the tip, then slowly began to move down the length, lapping up every drop of her pungent juices in her mouth and sending it straight into her stomach, her throat contracting visibly as she gulped everything down.

She glided her tongue over the cock until it looked as good as new and her jaw began to ache. She took a tissue paper out of the nightstand and wiped the dildo clean off her saliva. She gave her brother’s cock a farewell kiss on the flare and put it carefully into the box of the nightstand.

Twilight made herself comfortable on the bed and closed her eyes, preparing to fall asleep. “Good night, BBBFF,” she whispered, her magic securing the lock of the nightstand. “I’m looking forward to our meeting at the gala.”

A week flew by, and before Twilight knew it, she was standing in the center of the main hall with the gates of her castle breached, the nobles and gentry of all kinds that had for so long besieged her beginning to flow in and accumulate themselves around her hooves like a shoal of piranha around their prey. Twilight’s birthday gala had begun.

Greeting a pair of ponies in black suits whom she knew nothing about, Twilight proceeded for the final round of her castle to make sure that everything was as she had planned. At the great lobby the busts and sculptures from times more ancient than Celestia herself stood on either side of the corridor to meet the guests, their demeanors imperturbable. A little further on and music began to reach across the castle out of the grand hall. The musician ponies from Canterlot, the best in their craft, were chafing their hooves beyond blisters to bring the most beautiful melodies there were alive. For those who weren’t sated by music alone, a dozen tables ran the length of the hall with cushions to either side, all manners of delicacies and exotic fruits arranged along the middle of each.

Her mouth salivating, Twilight ignored the treats and sneaked around the corner to observe Pinkie Pie and make sure that the party mare wasn’t wreaking havoc upon the guests or involving them into dubious activities they would most likely take the wrong way. Convincing Pinkie to temporarily put aside her views on how a birthday should be celebrated had been the hardest part of the whole preparation process and Twilight hadn’t gotten away with it easy. Pinkie had demanded that after this ‘farce of a party’ was finished, she should be allowed to throw a ‘real’ party on her own terms the day later. Twilight had had no other choice but to agree. The consequences of her failure were too high to bargain over concessions.

At last, Twilight walked up to the giant crystal mirror not far away from the entrance hall and had a peek at her new dress. Twilight was nowhere near an expert on fashion but even she could safely say that Rarity had outdone herself this time. For a moment Twilight even felt herself not a simple bookish mare but a princess as she stared at the luxurious dark purple collar laced with gold and blue silk and the long flowing skirt that followed Twilight like a soft cloud. And gems all over the dress, hundreds of them, shone brighter than any star, captivating the eye and telling the dress’s own story that couldn’t be told in words – the story of beauty itself. Her dress was perfect. In fact, everything was perfect. It would be the grandest gala Equestria had ever seen and Princess Celestia would definitely be proud of her.

“Celestia!” A pitched voice interrupted Twilight’s musings and she turned away from the reflection to watch her number one assistant running in her direction. Spike slid to a halt beside her, almost doubling over in half as he tried to catch up his breath. “Celestia is here,” he muttered through a series of gasps.

A moment later Twilight was off and galloping towards her mentor, her heart racing with both excitement and a hint of nervousness. Twilight had made it clear to Spike that he was to inform her when Princess Celestia arrived. And though she trusted him to meet the guests and even had Rarity make him a black butler’s suit that he adored wholeheartedly, Twilight wanted to show Celestia to her castle personally. Her beloved mentor was, after all, the only reason she had the gala in the first place.

Twilight’s teleport to the castle’s entrance proved fast enough to offer a guiding hoof just in time as Celestia reached the main gates. She made to bow but was immediately stopped before she could do as much as tilt her head. Even after all those months, it was hard for Twilight to accept the fact that she was equal to the princess.

“Happy Birthday, my faithful student,” Princess Celestia said in her ever gentle voice that always served Twilight as some sort of sweet remedy when she was nervous. The princess of the sun levitated out a big book in a wrapper with her Cutie Mark emblazoned on it and hoofed it over to Twilight.

Twilight’s eyes brightened as she unwrapped her present, taking a look at the book’s title. Pony Of Time. The thick dappled cover felt rugged in her hooves and it had the faint odor of mold and sawdust that suggested the book hadn’t seen light for at least a thousand years.

“Is it what I’m thinking it is?” Twilight could barely hold the excitement boiling rapidly inside of her.

“Yes, Twilight.” Celestia gave out a mild smile. “It’s the original tome written by the hoof of Starswirl the Bearded himself.”

Twilight shrieked. Then she shrieked louder and began hopping in a circle. She did already have three copies of the book in her library but she could have never imagined getting hold of the original. Despite her mentor’s earnest protests, she groveled at Celestia’s hooves, thanking her profusely.

Twilight’s elated mood was short-lived, however. Soon Celestia’s long legs gave way to the view of the pony Twilight hoped to not meet here. “Blueblood,” she muttered under her breath. She immediately straightened herself up, fixing her mane and assuming the most imperturbable demeanor she was able to muster. Though she wasn’t familiar with the prince quite as close as Rarity had happened to be, Twilight’s coronation had resulted in a few conversations with him. It had been more than enough to realize that his characterization as an ‘asshole’ developed by Rarity was a complete underestimation.

“Still as servile before Auntie Celestia as ever, Twilight Sparkle,” Blueblood said, shuffling his hooves toward them, his expression so sour as if he had just eaten a whole lemon. “No wonder that she chose you to be her pet.”

“Watch your mouth, nephew.” Celestia threw Blueblood a stern look but otherwise didn’t express any indignation. “I chose Twilight to be a princess because of her devoted service to Equestria and her extraordinary talents.”

“Of course, of course. Sorry for my impoliteness, Auntie.” Blueblood showed a toothless grin, an ugly thing framed by his silk white fur and long golden mane.

Twilight ignored the remark despite anger boiling up inside of her and led the way into the main hall. As soon as the three ponies entered the lobby, a huge herd of gentry encircled Celestia and, on the pretext of business too crucial to the fate of Equestria, detached her from Twilight into another part of the room. Blueblood found neither a morsel of attention of his distant auntie nor any admirers and was left there standing beside Twilight.

“So...” An aura of condescendence emanated from Blueblood as if Twilight had to be thankful for just the opportunity to be speaking with royal blood. He did his best to keep his eyes off Twilight’s wings, pretending that they didn’t exist. “Good barn you have here. The biggest one among the peasants of this village.”

“Thank you,” Twilight said. “Not as big as your vanity, though. I fail to understand how it fits into Celestia’s castle. The princess must have a hard time finding fresh air that isn’t tainted with it.”

Blueblood gave out a sarcastic smirk. “It’s called prestige, dear. Some ponies are just born to be less worth than others. That’s how the world works. I, for example, have too many affairs of state to take care of as to waste my precious time on such nonsense as helping peasants to figure out who is which friend and with whom they are going to get drunk after a day in the field.”

For the first time since morning, Twilight was glad that her friends, especially Applejack, were too busy entertaining the guests as to not have to witness this. Otherwise, the gala would already have ended by this point with the tables flipped over and jaws broken.

She drew a deep breath and restrained herself from dancing to Blueblood’s tune and declaring that the only things he governed were a scatter of brothels and public houses, the only establishments in Canterlot that incurred losses to the kingdom and the only purpose of which were to satisfy Blueblood’s depraved appetites.

“You know,” Blueblood continued. “At my latest rendezvous with Auntie I ran into your photos from her school. A pitiful sight, really. Just looking at your insecure expression, the way you held yourself, trying to look as invisible as possible was more than enough to understand you for who you really are. Outcast. The worst candidate to help Celestia rule Equestria. But...” Blueblood paused for a dramatic effect, grinning. “The best candidate to follow her blindly. Be a little dog kept on a short leash.”

Twilight didn’t know why she kept listening to Blueblood’s insults. Perhaps because deep inside her she knew that at least some part of it was true. Her education, her status, even her friends. She owned everything to Celestia.

“Even as a pet, I’m glad to be—” Twilight didn’t finish. One moment a white hoof smashed against Blueblood’s face, and another moment he was sprawled on the marble floor of her castle, a bowl of potato soup on his head, a flipped-over table behind him.

“You better find another pony to bother, Blueblood,” said a male voice.

Twilight’s eyes went wide as she saw Shining Armor standing before her. He shook his hoof to ease the ache after the impact, his stern look turning into a smile as his eyes met Twilight’s. All around the crowd gathered to watch the scene and the whole hall became drowned in rustles and whispers.

“Did you just hit him?” Twilight didn’t need an answer. All the evidence was here before her, the most obvious of which being Blueblood’s right eye full of hatred and fear as he nursed his left eye with such a care as if it was a mortal wound sustained during a war.

“He had that coming for a long time,” Shining said simply. “I’ve warned him.”

“Shining, please. I’m not a little filly. I can stand up for myself. I saved Equestria more than once, you know.” Despite her best attempts to sound mature, Twilight’s words came out like the whine of a spoiled filly. Her brother was there for her and that was the only thing that mattered. He was there to defend her. To love her. Maybe not in the way Twilight’s mind was prone to imagine, especially during cold nights, but even so it was always more than she’d ever had. Meetings with her brother were the only time when she could feel herself being a mare.

Shining took a step closer, ignoring the crowd staring in his direction. “You can save Equestria a thousand times, but you will always be my little sister.” He stretched out a hoof to pull Twilight into a hug. “I missed you so much, Twily.”

Twilight didn’t waste time to accept her brother’s big embrace, wrapping her own hooves around his neck, their cheeks rubbing against each other. “I missed you too, BBBFF.” Twilight was about to snuggle even closer, perhaps even steal a kiss on Shining’s cheek, feel his warmth against her lips. She stopped herself however. Nothing in the world could cool down the passion toward her brother more quickly than a crowd of ponies surrounding her, evaluating every move of their new princess, ready to spread gossip at the slightest pretext, all the way up to Celestia’s ear.

“Where’s Cadance?” Twilight asked. Thinking of her former foalsitter, her friend, now her brother’s wife and the mother of his foal, was the second largest thing that tended to spoil the moment of their reunion. It wasn’t jealousy that bothered Twilight. She sincerely loved Cadance. But more importantly she loved her brother and wanted nothing more than for him to be happy with his wife. No, it was a sense of pure fear that fettered Twilight every time she touched her brother tighter than a sister should probably do. Cadance would never forgive the slightest advance on her husband, Twilight was sure. She would definitely have never forgiven it if she were in Cadance’s shoes.

“Cadance’s talking to Princess Celestia,” Shining said as he let go of Twilight and stepped away to point a hoof toward the far side of the hall.

Without her brother’s warmth surrounding her, Twilight suddenly felt as if a cold gust of wind swept over her. Even despite all the fears, she couldn’t bring herself to break the embrace first. And now when it was broken she couldn’t help but wish that it lasted a little bit longer.

The crowd parted as Shining stamped his hoof, leading Twilight behind him to the place where Celestia and Cadance rested, chatting gleefully. As soon as the show ended, the gentry left the siblings alone and returned to their previous affairs. Even Blueblood seemed to disappear.

The moment Cadance noticed Twilight approaching, she excused herself from the company of Celestia and trotted swiftly to the pair. “So glad to see you, Twilight!” she chirped, hugging Twilight who in turn awkwardly returned the gesture and greeted the Princess of Love back.

Pleasantries done, Cadance turned her glance to Shining Armor and frowned, disapproval painted on her face. “I sincerely apologize for my husband, Twilight. My dear Shiny managed to make a scene the first moment he got in here. But I’m sure it will not be repeated, will it, Shiny?” Cadance’s eyes narrowed in a way that suggested a promise of much more hurt than a mere black eye he’d given to Blueblood.

Despite the aura of menace emanating from Cadance, Shining stood his ground and made no sign to retreat. “I’m sorry, honey, but I can’t guarantee it. I will not allow anypony to say bad things and spread dirty rumors about my sister.”

Cadance huffed and returned to the cheerful self, a smile wide on her face. “Can’t do anything with him. You always had a special spot in my husband’s heart. Truth be told, sometimes I even feel jealous of you, Twilight.”

“Don’t be ridiculous, honey,” Shining hurried to defend himself. “You know I love you as much as Twilight. I would have done the same thing for you.”

Cadance giggled. “I know. I’m just fooling with you, dear. And by the way, Celestia is waiting for you to explain yourself.” She pointed to Celestia’s seat and Blueblood sitting beside her, baring his teeth like a mad dog.

Shining Armor cringed.

“Well, good luck, dear.” Cadance patted her husband’s head playfully. “And while you’re busy with my auntie, it’s just the perfect time for me to give Twilight my present. You would have gotten in the way anyway.”

“A present?” Shining lifted his brow skeptically. “I haven’t seen you prepare a special gift for Twilight.”

“Of course you haven’t. It’s a secret present between us mares.” Cadance shooed her husband away in the direction of Celestia and turned to Twilight. “Now, come on, Twilight. I’m so excited to give it to you.” Cadance looked around the hall, taking in its grandeur and numerous ponies in fancy dresses filling it to the brim. “But not here.” She tilted her head to Twilight’s ear, whispering. “Follow me to the balcony.”

Off they went, Cadance with a long stride that suited a princess and Twilight shuffling her hooves behind indecisively. “Is he going to be ok?” Twilight’s heart sunk as she saw her brother dissolve in a crowd of ponies. “Shouldn’t we be with him? I’m sure I can explain why Shining did it for me. Blueblood was really—”

“Shining is a big colt,” Cadance interrupted. “He’ll be fine. Plus, it’s just an obligatory small talk. Celestia knows better than anypony how much an annoyance her nephew is and doesn’t want to dirty her hooves in the whole situation more than necessary. She’ll make them say some fake excuses, shake hooves and that’ll be it.”

“I hope so,” Twilight said. She would never forgive herself if Shining got in trouble because of her. Images of Celestia’s wrath began to bubble up in the back of her head and before statistically impossible(or having a probability so small as to be ignored in accordance with any book on probabilities Twilight had read) scenarios consumed her mind, she decided to redirect her thoughts on the upcoming present instead. It must be some rare artifact, she thought. Something so powerful as having to be concealed from regular ponies. No, even from Shining. Perhaps some forbidden and illegal magic? Would she even have the guts to accept it? It certainly couldn’t be something too hazardous. Cadance would never put her in danger. A tinge of excitement ran through Twilight’s back. She would definitely accept it.

As they walked onto the balcony, Cadance glanced around and closed the doors with her magic. Having made sure that nopony could overhear them, she leaned forwards to Twilight who was now grinning eagerly. “Well, here we go, Twilight.” Cadance let out a puff of air before speaking. “You can fuck Shining Armor tonight.” She then straightened back up. “Now I said it.”

“Fuck...? Whom...?” Twilight’s mind stopped working. Had Cadance just said ‘fuck’? Had she meant sexual intercourse or was it a simple swear word? Of course Cadance couldn’t offer her to have sexual intercourse with her brother. It would be ridiculous. Twilight felt her fur begin to sweat and her heart pound like a drum. Cadance had no reason to even think about it. She had done everything possible to have Cadance not even think about it. Also, Cadance had no reason to even think about it. She had done everything possible to have Cadance not even think about it.

“Are you ok, Twilight?” Cadance waved her hoof before Twilight’s glassy eyes. “I know it might be sudden, but I’ve been thinking a lot about it. It would be better for both of us to—”

“Excuse me,” Twilight interrupted, her mind still trying to process that simple word – fuck. According to the Equine Global Dictionary, it was considered to be one of the words that had a multitude of meanings and is easy to misinterpret because of that. One of the many meanings of that word was to ‘damage or ruin’. Another one is ‘to treat somepony badly’. In other cases, it meant ‘to annoy’.

“Excuse me,” Twilight repeated. “But why would I want to annoy my brother? I have a good relationship with him. I mean, not as good as you have. You are his wife after all and I’m just a sister.” Twilight’s head began to spin, her breath ragged. She didn’t know why. There’s was nothing to worry about really. In accordance with any book on probabilities, the chance of Cadance knowing about her feelings for Shining was so dim that it could be ignored.

Cadance sighed. “Twilight, I know about your feelings for—”

“No, you don’t.” Twilight’s voice cracked and a tear slid down her cheek. “There’s nothing between me and Shining. You are wrong.”

“Twilight, I’m not here to accuse you of anything.” Cadance’s hoof touched Twilight’s cheek tenderly and wiped out the tear. “If anything, I’m here to help you to figure out your feelings. As the Princess of Love and your friend I can’t stand watching you torture yourself. You have to open your heart to Shining, otherwise the hole in your heart will only grow until it completely consumes you. That’s why I invite you to our bed tonight so you can sort things out between you and him. You will feel much better after that. I promise you.”

“You are wrong!” Twilight slapped Cadance’s hoof away from her cheek and ran away, more tears falling behind her.

“Twilight!” Cadance shouted but Twilight already left the balcony, rushing toward her room.

A stallion in a black suit and a mare in posh red dress began to laugh between themselves as Twilight came near them. Did they know about her secret as well? More laughs and giggles surrounded her, everypony looking her way, grinning.

“What is so funny?” Twilight’s eye twitched as she shouldered her way through the pair before her, almost sending them to the floor. “Do you like laughing at me?”

The stallion and mare looked up at Twilight, terrified, shaking in every limb. “Princess, we would never dare laugh at you. It was just a joke a friend of ours told us—”

“I swear to Celestia,” Twilight cried. “If anypony else knows about it, I will make your life hell. I will ruin you. Stomp every one of your dreams just as you have stomped mine!”

Everypony around Twilight took a step back, confusion and horror absorbing them like a sudden tsunami swallowing a city. Conversations ended; jokes turned into an incoherent gibberish.

With no pony to block her way anymore, Twilight ran on, taking a turn to leave the gala hall and making her way to the living quarters. She slammed the door to her room hard and walked in, as broken as she ever had. Her life was over and there was nothing she could do about it. She threw herself onto the bed and began to weep.

A hoof knocked on the door. “Twilight, please. Let me in. We need to talk.” Cadance’s voice. Twilight pressed her hooves against her ears to muffle the sound. It didn’t help. Cadance’s voice inside her head was much stronger and more agonizing than the one outside. I know you clop to my husband. Know how wet you become when you think about him. You dirty little whore of a sister. Wait till auntie Celestia knows about it. Or maybe she already knows that her star student disgraced herself before the most influential ponies of Equestria. Ha ha ha. You are done, Twilight. Next time you will think thrice before fantasizing about my husband.

“Just leave me alone!” Twilight cried.

“Twilight, open the door!” Cadance shouted back. “Get yourself together and stop imagining things that don’t exist. Nopony knows about anything, not even Shining. I’m here to help you, you idiot! Open the door.”

“But they laughed at me. Everypony laughed at me.” Twilight drew in a sniffle.

“They laughed because it’s a gala, Twilight. That’s what ponies do here. They tell each other stupid jokes and laugh at them, pretending them to be funny to not offend their companions. Now open this fucking door.”

A long moment passed, then Twilight’s horn lit and the door’s latch slid open. Cadance walked in, closing the door behind herself. “First I have to say I’m really sorry, Twilight.” Cadance sat down on the bed beside Twilight. “I didn’t expect your reaction to be so... so sudden.”

“Sudden?” Twilight turned to face Cadance, her eyes red and stinging from tears. “He’s my brother, for Celestia’s sake. And you... You are his wife. How can you offer me to have... have.” Twilight gulped down a big lump in her throat. “Have sex with him!”

“Love doesn’t care about such details, Twilight.” Cadance slid closer and put her hoof on Twilight’s back, stroking it gently. “Your love to Shining is no weaker than mine. Perhaps even stronger. I certainly have no right to deny that love of yours.”

Twilight frowned at that. She’d read in books that love had no boundaries, of course. Brother and sister romance novels were the ones she enjoyed the most. But she was different! She was a princess. Celestia’s personal student. Generations of foals were going to look up to. And, besides... Shining had never seen her as a mare. She would have noticed otherwise. Of course he loved her but it had never been the depraved passion she had for him.

“How did you know about... him?” Twilight asked. She still couldn’t believe that she had messed up somehow. Had it been that one time when she hugged Shining longer than necessary at his wedding? How could she have been so stupid?

“I’m the Princess of Love.” Cadance smiled. “You can’t hope to hide this stuff from me. Truth be told, I knew Shining had been more to you than just a brother since you were a filly. I thought it was just a teenage crush that would clear up by itself. I thought that when you grow up, you’ll find yourself a nice stallion and forget about the feelings to your brother. I was wrong. I was talking with your friends the other day and they told me everything about your failed relationships with other ponies.”

“Rarity.” Twilight scowled. “I’m fine with my personal life as it is now. There’s no need to worry about it.”

“When was last time you had sex with a pony, Twilight?” Cadance asked, her tone serious.

“Does it really matter?” Twilight turned her eyes to the floor, frowning. Being a virgin is not the end of the world.

“When was last time you kissed somepony then?”

Twilight didn’t answer, continuing to stare pass Cadance. Though she’d never kissed on the lips, she had stolen enough kisses on the cheek from Shining to be happy about it. She doubted this answer would please Cadance, though.

“Oh, my.” Cadance sighed. “Everything is even worse than I expected. I shouldn’t have dragged on with it for so long. I should have helped you much earlier. I’m sorry for all those days and nights you felt broken and alone because of my hesitation. I’m really sorry, Twilight.”

“But you don’t have to be sorry. You can’t help me. Nopony can help me.” The familiar bitterness returned to Twilight’s throat. “He will never love me the same way I do. And even if he did... I just can’t. I have my responsibilities. Even if it’s nothing to you, it is not nothing to everypony else. It will be a raging scandal. A crushing blow to reputations of all ponies I know and love.”

“I tell you what, Twilight, we all have a skeleton in the cupboard. Celestia, Shining, your friends, me, everypony. The secret here is to not let it out in public.” Cadance gave Twilight a wink. “That’s the first lesson Celestia should have taught you when you became a princess. You are right, it would be a scandal. That’s why we’ll make all the preparations necessary so that nopony will ever know about it. Consider it your princess training. Saving your appearance is a part of your job. And believe me, ponies will spread all kinds of dirty rumors about you anyway, not even a quarter of them true. Your role here is to be strong, to not let common folk subdue you to a trembling mess, fearing to take a step.”

“How can you be so confident of this?” Twilight’s hoarse voice whispered. “Even just by talking to me about this your reputation is at great risk.”

Cadance laughed, a ringing clear sound that filled Twilight with confusion. “Oh, Twilight, you’re such a little naive thing.” Cadance reached down to couple Twilight’s cheeks in her hooves, kneading them lovingly. “As I said earlier it’s because we all have a skeleton in our cupboard. Me? I have too many already stuffed there for another one to make any difference. If ponies knew everything that goes on in my and Shining’s bedroom, The Crystal Empire would have fallen apart long ago.”

“What do you mean?” Twilight asked puzzlingly.

“It’s a story for another time and I promise you I’ll tell you everything you want, but not before we take care of your problem here first. Right now, all I can tell you is that it’s not the first time Shiny and I share our bed with somepony else. Or for that matter, much more... exotic creatures. So your presence won’t scare him away.” Cadance paused, laughing, then stopped and cringed slightly. “Well, at least not as far away as you might think. I won’t lie, I’ve never noticed him having his eyes on your flanks long enough to make out any details. But we can fix that quickly. You’re one sexy mare, Twilight. And I’ve been training Shining long enough to have him tell a gem from stone. He learns fast.”

Twilight’s jaw fell agape. She always thought herself to be a pervert and couldn’t even imagine that somepony else could beat her in that. And of all ponies, her own brother and her friend plus former foalsitter? Two ponies she had known her whole life? Perhaps, she was even less experienced in love matters than she could think of. Bookworm or not, Twilight wasn’t stupid and understood that books hardly scraped the surface of how love really works but still she wasn’t able to hide her bewilderment. “You and my brother? With whom?”

“Mostly servants,” Cadance said nonchalantly. “It’s just sex really. Nothing more. It allows to free oneself of any residue sex energy and guarantees that my husband will never have a mere thought of looking at another mare behind my back. And if he would be foolish enough to look at another mare, he knows that he would be left without his head and another important parts of his body.” Cadance paused. “Except you. You’re not another mare. You’re my little Twily. You are family. I hope I shouldn’t remind you about it ever again. Tell me you understand this.”

“I am family,” Twilight mumbled under her breath, sneezing her tears in.

“What does it mean, Twilight?” Cadance locked Twilight with a stare.

“That you will be always by my side and help me no matter what.”

“Good. I’m glad that we got over it.” Cadance said as she pulled Twilight to her chest and hugged tightly. “Unfortunately it also means that I can’t force you to do things. You have to make this decision yourself. Shining and I will stay at your castle a few days before we return to the Crystal Empire. I will be waiting you in our chamber tonight. Don’t worry about anything. Nopony will ever know about this whole ordeal and we can go about it as slowly as you’re comfortable with. Even Shining won’t know a thing before you get more or less used to being close to him. Promise me that you will at least think of my proposal.”

“I will,” Twilight lied. There had been times when the thought had crossed her mind to just let it all out to Shining, to sink into his chest and finally say how much she really loved him. But that time had long gone. She was no longer a little filly to allow herself such silliness. Cadance was right. She wasn’t just another mare. She was family. She was his own sister. Ponies would forget fast a petty flirt with a maiden. But a romance with a sister? She could put herself at risk if she really wanted to but not the ponies who relied on her. She would never forgive herself if Shining or Celestia had serious problems because of her selfishness. It would be much better if the things stood the way they did, without that depraved love of hers.

“I hope you’ll make the right decision,” Cadance said. “But whatever you decide, I will always support you no matter what.” Cadance extended her hoof and helped Twilight from bed. “And what has Celestia taught you? Definitely not how to be a princess. Look at yourself, got messy like a little filly.” She wiped away Twilight’s dried tears. “Here, now it’s much better. Don’t forget to remind me that after we deal with this problem of yours I have to teach you how to behave like a princess. Perhaps you don’t have to be strong all the time, nopony can, but you do have to look like that. Now go on and show them how strong you are.”

Twilight did as she was told and left all her worries behind the door to her room. Almost all of them, anyway. Enough to look as happy a princess as it was expected.

As the princesses trotted into the main hall, they saw Starlight appear around the corner. The mare had been seemingly waiting for them after Twilight’s boisterous exit. She walked up to the princesses, falling into a trot beside them. “You really scared me there,” Starlight said. “I thought you’d finally broken down under all this stress.”

“I’m fine now.” Twilight assumed a smile. She didn’t really feel like that but Cadance was right. She couldn’t let ponies see her sulking around and ask questions about what had happened.

“Are you sure? Maybe I can help you somehow? I can greet the important guests if you want me to.”

“Thank you, Starlight, but I’d better do it myself.”

“Well,” Starlight stretched the word awkwardly as if somehow knowing that Twilight was faking her cheerfulness. “I’ll then go check on Pinkie and see if she didn’t kill somepony accidentally.”

“Thank you,” Twilight said sincerely. One thing she loved about Starlight the most was that the mare never pushed the matter. Pushing was the last thing Twilight needed right now. Her head was still buzzing with confusion and Twilight doubted she could ever sort it out without sleeping through it first. Her only mission for today was to get through it and see what’d happen next.

“See you later, then.” Starlight made to turn around but Cadance stopped her.

“Actually, you can help me instead,” Cadance said, moving closer to Starlight. “Is it ok with you?”

“Princess Cadance?” Starlight startled back, seemingly completely unprepared to talk to a princess who wasn’t her closest friend. “Of course, I’ll help. W-what do you want me to do?” She stuttered.

Cadance put on a sorrowful countenance. “It’s something personal and Twilight told me that you’re good at keeping secrets.”

Starlight gulped down and nodded.

“Well, the thing is... I recently noticed that my husband started to look at other mares. Perhaps it’s just my paranoia but I want to be sure that he is still faithful to me. I want you to test him.”

“Test him?” Starlight’s eyes narrowed with confusion.

“Yes. Talk to him. Flirt. Use your feminine charm. I’m sure I’m not the one to tell you how it’s done. I’ve seen enough gentlecolts pursuing you with their eyes today. You’re quite a popular mare indeed.”

“I’m not sure we’re talking about the same pony...” Starlight’s eyes wandered around, looking for escape. “I’m not really that... social.”

Cadance smiled gently. She stretched her hoof to Starlight’s chest where her heart was. “You just have to believe in yourself.”

Starlight slowly turned her head to Twilight, screaming silently for help but Twilight just shrugged. Any other day she would have helped her student without a second thought but right now she definitely didn’t feel like making eye contact with Cadance, let alone arguing with her. Whatever plans the Princess of Love had for Starlight, she would have to go through them without her support.

“Perhaps I can do it but...” Starlight began to give up under Cadance’s pleading expression. “What if he actually falls for it? I mean, of course he will never do.” Starlight wiped the sweat on her forehead away. “I’m sure Shining Armor loves you and only you, Princess.”

Cadance laughed softly. “Then it wouldn’t matter, would it? You can do whatever you please with him then. The Princess of Love hardly deserves a stallion who can’t keep his prick in his sheath. What’d you say?”

“Well, y-yeees.” Twilight, please save me. Twilight could literally read Starlight’s mind. Somehow her student had managed to send an electromagic wave straight into her brain. She sure was a very talented unicorn.

“You’ll be fine,” Twilight said. “Cadance is the only pony my brother loves. He’ll never cheat on her. Just drink a few cocktails with him and that’ll be it. Imagine it’s your homework on how to make friends.”

“When you put it this way, it sounds almost innocent.” Starlight let out a puff of air, getting herself together. “Just a new friend. I can make it.”

“Thank you so much,” Cadance said, giving Starlight a brief hug. “I’ll be awaiting your report on how everything has gone tomorrow.”

“Report?” Starlight giggled, giving Twilight a knowing look. “That is a homework friendship assignment. Well, I guess I’ll be going then.” She returned around with stiffness in every limb and ran away.

“I’m afraid I have my business as well,” Cadance said as they entered the hall. She turned Twilight’s attention to the pair of nobles who backed away as soon as they saw the princesses, the same fear in their eyes as the one Twilight had left them with when she had been running through them to her room. “I think you have some work to do too. I was trying to calm them but it’s better if you do so yourself and apologize. Your behavior was indeed very inappropriate.”

“You’re right. See you later then.” Twilight wanted to hug Cadance goodbye but couldn’t bring herself to do that. She doubted she would be able to ever see Cadance the same way she’d seen her before. No matter how encouraging her former foalsitter’s words might be, she still felt herself a traitor while standing beside her. However, Twilight hadn’t the last say in that matter as Cadance pulled her close to her chest and hugged tightly.

“Chin up, Twilight. Remember what I said.” And Cadance was gone.

Twilight stood unmoving for a few minutes, then took a deep breath. Well, time to fix your mistakes before Celestia hoofs you out, Twilight. She slowly approached the pair of ponies to make her amends. Contrary to her fears, the two ponies turned out to be quite nice and accepted her apologies without complaint and helped her to convince the rest of the crowd that Twilight wasn’t some sort of a crazy pony but merely a fledgling princess who had stressed out under the pressure. She also successfully managed to evade Shining while doing so. It wasn’t that easy and soon she found herself jumping from one conversation to another, from a mayor of an Equestrian town to a chief of a most distant village, all the while awkwardly excusing herself and promising to visit every of those places. Of course, she couldn’t run away from her brother forever and soon was cornered with no other choice but to face him. He looked as if he was trying to run away from somepony too.

“Hi, sis. Do you want the latest news?” He laughed as he approached her. “I think your student is trying to seduce me.” Seeing Twilight’s complete lack of reaction, he added. “Well, it doesn’t sound funny now but you should have seen that. I don’t mean anything rude really. Starlight’s a cool pony and all that but where in Tartarus did she get that idea to hit on me? She sure didn’t forget I’m married, did she?”

Twilight kept silent and moved on to welcome the sheik of Saddle Arabia who had just entered her castle with a flock of retinues and a herd of his wives. And though the etiquette demanded that it was enough to address only the sheik, she took her time to approach every pony of his escort individually and shook their hooves.

“I’m starting to think that you’re deliberately ignoring me, little sis,” Shining said, dragging on behind her.

“Well, maybe,” Twilight said half-heartedly, turning her eyes away from him to the next guest.

“Is it because you’re still angry at me after beating Blueblood? You have nothing to worry about really. I’ve already settled everything with Celestia and made sure that you have nothing to do with it.”

“It’s not that.” Of course it wasn’t. How could she be angry at him about such nonsense, especially if he’d done that for her? It was one of the reasons she loved him so much. He would do anything for her before even realizing in how much trouble he might be because of that.

“Then what?” Shining doggidly followed Twilight, unceremoniously ignoring ponies who were trying to stir him into their conversation. “It can’t be that you’re still sulking over my missing your previous birthday, can it? It was a very important mission that demanded I prepare the defensive spell in time. Well, you already know the details.”

“It’s not because of that either!” Twilight fumed, partly because of her brother’s persistence but mostly because she knew that the only problem here was her and her alone, and that she would never have the guts to admit it to him.

Shining made his way through a crowd of nobles to stand before Twilight. He looked her in the eyes, concern written on his face. “Twilight, you know you can trust me. Say what is bothering you. I’m sure I can help you with it.”

“Why is it so stuffy here?” A tear almost escaped Twilight’s eye but she stopped it in time. “Sorry but I need some fresh air. If you excuse me.” She shook hooves with some gentry and hurried away to the solitude of the balcony where nopony could notice her stinging eyes.

Once at the place, Twilight leaned against the balcony rail and watched pegasi chase clouds in the distance. The scene was somewhat soothing.

“Twilight, stop running from me.”

Twilight said nothing and continued staring into the distance.

“Twilight, don’t be a spoiled filly. You know I’m not going anywhere until you talk to me.” Shining put a hoof on her back and began to caress it slowly while rubbing his side against hers. There had never been a moment in her life when she didn’t feel better after her brother’s affection, even during the most severe depressions when she was a foal. Now? Now she felt as sick and broken as never before.

She brushed her brother’s hoof away and took a step back. “Just leave me alone!” Twilight boomed, her inflection commanding. A near replica of Royal Canterlot Voice.

Twilight let out a desperate sigh. She would never have thought that she would raise her voice to her brother. But it hurt so much being so close to him and unable to share her feelings with him. At least it helped get some of her anger and frustration out. Though it didn’t last long. Soon a new, much stronger void replaced the previous spot in her heart. “Please, just leave me alone,” she whispered.

“Fine.” Shining placed his hoof back on the ground and yawned. “If you insist. I get that you’re not in the mood to speak to your big bro.” Her sight on the clouds, Twilight heard Shining beat the dust out of his jacket. “Then, as The Prince of The Crystal Empire, I demand a conversation with you, Princess Twilight Sparkle. Our nations do not do as well as desired and we have serious matters to discuss.”

“What?” Twilight frowned. “If it’s another game of yours, I’m not in the mood for it either.”

“Watch your tongue, Princess.” Shining said extravagantly. “The matters of the Empire is not a mere game. Our nations have already had enough of differences and disagreements. And if you continue to disrespect the official representative of The Crystal Empire by having your head turned away to the clouds, I’m afraid I have no other choice but to declare war on you and your ponies.”

Twilight couldn’t hold back a snicker at the absurdity of her brother’s proclamation.

“Do not underestimate me, Princess.” Shining puffed the air from his lips for a dramatic effect. “I’m going to abduct you and have my best torturers tickle you until you agree to speak to me properly.”

It took Twilight an effort to keep a smile from blooming on her face as she tried to imagine that. She shook her head exaggeratedly.

“You don’t believe me?” Twilight turned just in time to see Shining’s sly grin. “I will begin a war without a second thought for you, Twilight. You and Cadance are the most important ponies in my life. I’m willing to do whatever it takes to have you both by my side.”

Twilight continued to keep silent. She knew it was just a joke but something inside her told her that some part of her brother’s proclamation might be quite serious. She wondered if her brother was really ready to sacrifice the lives of innocent ponies just to get her attention. She stared at Shining’s face, his broad cheekbones, his smiling lips. Everything in her brother was perfect. There was no need to get somepony hurt, that was for sure. Her soul and heart had already long ago belonged to him. All she needed right now was a little time to sort out her thoughts and feelings. It hurt her that her brother couldn’t understand that.

“So it’s war then, Princess Twilight Sparkle.” Shining Armor watched Twilight’s pursed lips with expectation. “Your silence left me no choice.”

Twilight’s legs abandoned the crystal floor under her and she felt suspended. A pink aura surrounded her whole body and moved her sprawled form on Shining’s back, her forelegs dropping over her brother’s right side, her hind legs over the left.

“Shining, what are you doing? Put me down right now!” Twilight cried, confusion and anger fighting over her emotions.

Instead of the answer, Twilight was met with a bright light emanating from Shining’s horn. The world around her collapsed into a jumble of colors and she lost any notion of space. She wanted to scream but a sudden need of sleep overwhelmed her and she passed out, her head falling over on her brother’s side.

Twilight opened her eyes slowly, an echo of the bright explosion that seemed to have happened just a moment ago buzzing in her head. For a while, she was doing nothing but staring at the grass swaying before her eyes, wondering how in the hell it managed to have grown through the crystal floor of her castle. Then, after squinting, she discovered that there was no actual floor nor any crystals but a dark blanket of soil spreading in all directions. She risked to lift her dizzy head up and was immediately met with bright greetings of the sun that only affirmed Twilight’s theory of her not being in the castle anymore.

A warm wind played with Twilight’s mane as she tried her best to shuffle her hooves, attempting to take a step, but to no avail. Her hooves just spun around in the air, not reaching the ground. She tried faster, flailing her hooves around until she suddenly punched something soft under her. It felt like a pony but it wasn’t her body. She glanced under her belly and discovered a white fur of a pony she was sprawled on. She reflected on the last events and, after a moment of deduction, concluded that she was still lying on her brother’s back. What had really happened she couldn’t determine yet. She needed more information.

Joyful cries diverted Twilight attention from examining her brother’s back and she turned her head toward the direction of the sounds. A long line of ponies, many with their foals, moved through a series of turnstiles, all chatting excitedly. A short glance at the beginning of the line revealed a set of buildings all too familiar to Twilight. Wide bright fabric ran along the walls and up bastions, stretching across the top and serving as a roof cover, numerous balloons adoring every inch of it. And further in the distance... Were it waterslides? Twilight couldn’t believe her eyes. There was no amusement park here in Ponyville. She moved her gaze further. A Ferris wheel? It certainly looked like one. The biggest one she’d ever seen, ever ridden...

That just didn’t make any sense. Twilight could swear this park looked exactly the same as the amusement park she’d visited so many times with her family back in Canterlot. No, it was the amusement park she was thinking of. Twilight knew it too well to mistake it for something else. Best moments of her foalhood she’d spent inside those dazzling walls, best moments during which she and her brother were especially close.

“How...?” Twilight stopped abruptly as the realization dawned upon her. Those bright lights she had seen and the dizziness she currently experienced must have been the result of Shining’s spell that had teleported both of them from Ponyville all the way to Canterlot’s Amusement Park. Twilight jumped off Shining’s back as the sudden shock of the realization shot through her. She hurried around to face her brother.

“Are you crazy?” Twilight looked up at Shining, her heart beating hard in her chest. Even teleporting one pony across such a distance was considered especially risky. It demanded a lot of the caster’s energy and concentration and any mistake could reflect badly on the caster’s horn with a probability of inability to use magic anymore. In worst-case scenario it meant death.

Shining Armor’s resolve didn’t waver under Twilight’s penetrating stare and he held his ground firmly like a tree taking its root. “I pledged that if you weren’t going to talk to me, I was to kidnap you and hold you hostage until you changed your mind. You should have taken your big brother more serious.” He chuckled.

Twilight ignored her brother’s foalish behavior. “How do you feel? Are you alright? We need to go to a hospital and have your horn checked if there are any fractures. It might be something serious.” She watched Shining with both deep worry and anger at how reckless he sometimes might be.

“I’m fine,” Shining Armor said, rubbing his horn, its tip blackened. “Just got overheated. It’ll go soon. Gotten much worse while serving in the Royal Guard.” He managed a broad smile. “But I’m afraid we’ll have to take a train on our way back to Ponyville. Not sure if I can repeat this trick one more time today. Well, any trick for that matter.” He pointed at a thin thread of smoke curling up from his horn.

“Are you sure it doesn’t hurt?” Twilight lit her horn and guided her magic to coil around her brother’s horn, probing it carefully to make sure that it had no damage. She wasn’t an expert at medicine magic but knew more than one thing on how to perform first aid if a situation arose. Having not found anything serious, she let go of Shining’s horn and took a deep breath of relief. Her brother had always managed to get away with his mischief since they were foals, the thing that she could never contest him in and when she dared to try, she would always end up before their parents, punished.

“I swear I’m fine,” Shining said, his horn beginning to slowly return to its normal white shade. “You know I would never hide anything from you, little sis.” He put a hoof on Twilight’s head and ruffled her mane. “Now, come on, we don’t have that much time before Celestia realizes that we are gone and sends a rescue team for us. Have you ever seen their stiff faces?” Shining laughed. “Those guys don’t know how to hang out at all.”

“Celestia?” Twilight remembered with a shock that she was supposed to play the pivotal role in today’s gala. Ponies from all over Equestria had come their way to meet with her. And now, she was gone without a word of farewell or explanation. “We need to return!” Panic began to rise in Twilight’s voice. “I have to be back in my castle before it’s too late. Celestia will kill me!”

“No. She will kill me,” Shining amended. “Remember, I am the one who abducted you. You’re just a victim here. And I am your torturer. Speaking of which...”

Before Twilight could react Shining leaped forward, wrapping his hooves over her shoulders in a big hug, and pulled back, plunging his body into the soft grass. Twilight didn’t have another choice but to follow after him as her brother’s fall carried her onto his chest, their faces mere inches from one another.

Twilight lifted the soiled skirt of her dress and made to protest but found herself laughing as Shining dived under her and started to tickle her legs and upper body, his lips flat against the fluff of her chest, puffing flows of warm air onto it.

“Stop it,” Twilight somehow managed between giggles. She tried to get up but failed miserably. “You can’t just—” She broke off with a burst of wild laughter as Shining began to tickle the frogs of her hooves, neutralizing her completely. She was at the mercy of her brother and he knew it. “Stop it, Shiny. Ponies would think—”

“What would they think?” Shining lifted his head up from the business of tickling his sister’s soft chest with his breath. “We are just brother and sister. We often did it when we were foals and you never minded it.”

“But we are not foals anymore.” There was a trace of grief in Twilight’s voice. “And I have responsibilities. Important responsibilities. Celestia and the whole of Equestria count on me.

“It’s nowhere near as important as my little sister’s birthday. And I will not allow those pompous ponies to ruin it, no matter what plans Celestia might have in store for you.”

“You can’t just pin me down here and hope that I give up everything for a day of fun with you,” Twilight protested, using a moment’s respite from the tickling to catch her breath.

“You better not dare me, Twily!” He smiled and dived under her again, this time tickling all Twilight’s weak spots at once, down from her hooves and all the way up her spine and neck, his moves fast and precise.

Twilight burst into another fit of laughter, more powerful than ever before. “It’s not fair! It’s not fair!”

“I can do it all day, little sis. All the day through until you give up and agree to spend time with me.”

“I give up! I give up!” Twilight couldn’t take it anymore. And who was she lying to? She couldn’t live without her brother. No matter how hard she tried to convince herself otherwise. Things just didn’t work that way. He was as much a part of her life as her heart was a part of her body. She couldn’t just remove it and pretend that everything was fine.

They lay still for a long while, the wind whistling a soft melody to them, the grass swaying around them gently. Twilight snuggled up to her brother closely, feeling his warmth, holding him tight around her hooves as if afraid that he might vanish if she weakened her grip. As if it might be just a sweet dream. The last time they snuggled together in the grass had been when she still went to the School for Gifted Unicorns, way back before he’d moved on to live with Cadance. She still remembered his touch, his strong yet gentle embrace as if it were yesterday. She could never hope to relive it again. Until this day... Here she was, her dream alive and overwhelming her being.

“Thank you,” she whispered.

“It’s too early to thank me,” Shining said, his hoof brushing the small of Twilight’s back. “Wait till you see all the stuff I’ve planned for us. We are going to visit every amusement ride, and this time I’m going to win that Teddy Bear you wanted so badly.” He flexed his right foreleg and thick muscles began dancing on it. “I’ve been preparing, you know.” He laughed.

He still remembers. Twilight shook her head unbelievably, a smile escaping her lips, her embrace tighter.

“You smell good,” she said. The realization that she’d stepped onto thin ice came a moment later. She had promised herself that she wouldn’t allow her perverted obsessions to stay in the way between her and her brother. He didn’t deserve to be a victim of her egoistic desires.

“Well, thanks.” Shining’s cheeks blushed slightly, just enough red in them to be noticed. “Cadance picked out a deodorant for me. She’s quite an expert at them.”

A long moment of awkward silence followed.

Twilight was first to become uncomfortable enough as to decide to get up from the grass and offer to head off for the Amusement Park.

“Two adult tickets please.” Shining Armor took out a pouch of bits from his jacket.

He pulled Twilight to himself and they walked through the gates of the park together, his hoof hovering over her protectively, separating her from the dense crowd stamping in and out of the park, ready to deflect anypony who didn’t pay enough attention to where they were going and had enough stupidity in them as to run into his little sister.

After jostling the last pack of ponies the siblings squeezed themselves out of the thin neck of the turnstiles and now stood before the vastness of the park, any of the numerous rides theirs to claim. The sun shone hotly in the cloudless sky and without any discussion or arguing it was decided that the water rides would be the perfect place to start.

“I’m so glad we made it to the outdoors,” Shining said, stripping himself off his jacket as the siblings approached the park’s storeroom. He tucked his clothes neatly away into a storage locker and drew a big breath of relief after his body became free of its confines. Twilight remembered that Shining never really loved wearing a uniform and always thought it to be too gaudy and unnecessary, and always strived to be as close to the common folk as possible. He loved to say that a pony who has nothing to hide has no need for any clothing and that no dress can compete with the diverse coats that nature has given to ponykind.

Twilight couldn’t agree more on both of those statements as she devoured her brother’s exposed body with her eyes. His smooth white fur, his broad muscular chest, his strong forelegs, all of this made her appreciate the expanse of her dress that so adeptly hid any secrets that her rear part was so eager to give out to the world. She could still control herself but the mere thought that she might snap at any moment and that ponies might find out the real degree of her excitement from a whole day with her brother sent a shiver to race down her spine. She dropped down on her rump and clutched at her dress with both of her hooves, afraid that it might somehow slide off her as if it were a life jacket and she was about to go out in the middle of a tsunami.

Shining Armor gave Twilight a quizzical look. “What’s up, Twily? Are you going to be swimming in a dress?” A smile began to stretch across his face but it quickly turned into a thin line as Twilight returned him a nod and he realized that she was utterly serious.

“C’mon, Twilight. Don’t be ridiculous.” Shining shook his head exasperatedly. “You’re not at the gala. Nopony will make a scene if they catch a glance of your naked ass.”

They might. Twilight gritted her teeth in frustration. Why did she have to be so perverted? Her brother gave her one of the best days in her life and here she was, ready to ruin everything simply because she saw in him a piece of meat to satisfy the itch between her hind legs. She hated herself so much for that.

“What about a swimsuit then?” Shining scratched his chin wistfully. “You can borrow one at the reception desk. I heard they even have ones with a skirt that’s got frills at the edges. Is it fancy enough to satisfy your Majesty buttocks’ refined taste?” he asked playfully.

“Swimsuit?” Twilight rolled the word in her head. Somehow the image of her rump in a tight spandex material seemed even more unsettling than the thought of being naked but at least a skirt should conceal the details of her excitement pretty convincingly. It was better than nothing and she couldn’t sit out the whole day here. Shining might assume that she simply decided to sabotage the tryst because she didn’t want to hang out with him anymore. Twilight couldn’t tolerate such a possibility and calculated that the risks of being busted were so small that they could be labeled as insignificant. “Swimsuit should suffice,” she said, then got up from the floor and made for the door, her brother following her.

The siblings returned to the locker room after Twilight had looked thoroughly through the whole wardrobe in search of a swimsuit with the appropriate skirt length. Unfortunately, as it turned out, the design of swimsuit wasn’t created as a means of hiding the arousal of horny mares. Twilight swore to address this problem with Rarity when she returned home. As for now, she carried a blue swimsuit with a skirt so short it could barely cover her buttcheecks. If anything, the ‘skirt’ only helped in laying ponies eyes upon her rear end and the spandex would serve to punctuate the contour of her vulva should it swell with arousal.

Stupid swimsuit. Twilight began to regret her stubbornness regarding the dress and should have just stripped it off when she got a chance. She briefly considered to throw the useless piece of cloth away but thought better of it. Shining had been waiting so long for her while she tried to choose the right thing. And he had already paid for it. Twilight couldn’t bring herself to tell him that everything had been for naught.

As things stood, she had no other choice but to try to keep her aroused reproductive organs at bay. She had to throw any thought of her brother as a sexual object away from her head and under no circumstances take a gander at his perky ass and a pair of plump big balls that she had for so long craved for. You hear me, Twilight? Don’t look at your brother’s ass! Twilight drew a deep breath. Then another. And another. Okay. I can do it.

Twilight eased herself into a swimming suit and spun around, showing off her feminine curves to Shining.

“You look cute,” Shining Armor said, smiling.

“Thanks. Now let’s go have some fun!” Twilight bumped her flank against her brother’s and dashed off toward the outside.

The sun’s warm beams brushed Twilight’s back as she hurried along the stairs of a first water slide to take the descent first. One step ahead before Shining, she jumped on the top platform and ducked into the pipe of the slide. The water carried Twilight along the twisted turns of the slide, splashing against her face, and before long she found herself crying as she flew out of the pipe into the air, the gravity doing the rest to hurl her down into the pool below. Swimming in the warm water, she watched Shining bolt out beside her into the pool. Her already wet mane had become even wetter after her brother’s impact against the water surface and she began to splash water at his face to take her revenge. She regretted about it quickly as Shining didn’t waste time to answer with a water volley of his own, twice as big as Twilight’s.

In such a joyful competition the siblings spent the best part of the next two hours, riding down every water slide the park had to offer. They ended up lying on the sunbeds by the pool, exhausted and laughing, and decided that their next stop would be horseshoe-throwing, a calmer activity with more opportunity for teamwork. They pitted against another four pairs and were beaten into second by a tall grey stallion unicorn and a yellow pegasus mare in a wonderbolt uniform. Twilight shook hooves with the mare and waited while Shining was chatting excitedly with the stallion who was swinging his hooves wildly, highlighting the major points in the story he was telling. By the scraps of their conversation, it was clear that the stallion served in the Royal Guard and was a good friend with Shining. Eventually, Twilight got tired of waiting and butted in to remind her brother that he still had his little sister to entertain at her birthday. Shining rubbed the back of his head apologetically, blushing slightly. He shook hooves with his old comrade and promised Twilight to make up for every minute he’d missed.

His words weren’t empty and soon her brother reformed himself by winning the first place in High Striker competition, sending the puck to almost break through the bell. Twilight squealed with excitement as the operator levitated a huge Teddy Bear on her back. She had had her eyes on the toy since her first visit to this place when she was a filly.

The siblings’ next stop was at the Photo Booth. Twilight hugged her brother tightly as they stepped in and pressed her cheek against Shining’s, smiling, her Teddy Bear squeezed between them. A light blinked and the moment was stored on the photo paper. They put on serious faces then, imitating business ponies. Twilight crossed her hooves before her and Shining stretched his foreleg out in accusation, their eyes narrowed. Another flash of light. Twilight stuck her tongue out and placed her hooves above her head like two long rabbit ears. She grimaced as Shining crossed his brows, his lips pouting. Another flash.

The sun began to lose its warmth by the time the siblings entered House of Horrors. They stepped into the train and sat down on their places next to each other. An evil laughter began to play and the train moved. After the first turn a skeleton dropped down from the floor and started moving its bony limbs attached to the strings above chaotically. It wasn’t scary but Twilight pressed herself against her brother nonetheless, pretending to be afraid. Shining smiled and wrapped a hoof around her tenderly, moving the skeleton with his other hoof aside as the train passed by it. Even when their journey had ended, Twilight was still snuggling to her brother tightly, blaming everything on the ‘horrors’ behind them.

The Ferris wheel was next on their way around the park. From the highest point Twilight could see Celestia’s castle and even the windows to the room she had been studying magic in. She squinted her eyes and made out a tiny brown spot far far away. Their home. Twilight sighed, remembering old days with her brother living there. Life had been so much simpler back then. Their relations had been so much simpler...

By the evening Twilight’s belly began to grumble and the siblings decided to walk around the Gyro Tower to cut their way straight to the cafe Amorous Harp standing by the shore of the lake. Once inside, they ordered daffodil sandwiches, chamomile and peach salad, and two Manehattans to toast Twilight’s birthday with.

“For the best sister of the universe.” Shining raised his glass and clinked it against Twilight’s.

“And what about my other versions in the multiverse?” Twilight grinned, swirling the remnants of the orange liquid in her glass.

“I doubt they have such a cool brother. So who cares?” Shining laughed and Twilight smacked him in a shoulder playfully.

“It’s the best birthday I’ve ever had,” Twilight’s jab had turned into brushing motions along her brother’s shoulder. Somehow she felt lightheaded though she knew the drink had nothing to do with that. It was nothing compared to the whirlwind of emotions a day with her brother had brought down upon her. “I don’t even know how to make this any better.” A dirty thought flashed across the back of Twilight’s mind but she put it down before it could blossom into something vivid.

“Well, I have an idea.” Shining gripped her hoof with his own hooves gently and got up from the table, rounding on Twilight. He pulled her from her seat and led away from the dining zone to a spacious area in the center of the hall. He gave a whistle and the musicians on the stage shifted, turning a lighthearted gibberish of their instruments into a steady slow rhythm of the waltz.

“I hope you still remember how to dance, little sis.” Shining’s smirk took up half of his face. “Don’t want us to be ashamed before all of these ponies.”

“Oh, you wish, big brother. I was the second best in Celestia’s dancing classes.” Twilight grinned, standing up on her hind legs while using her brother’s shoulders for support.

Shining followed her, rearing up and wrapping a hoof around Twilight’s back.

Twilight’s world spun as her and Shining’s hooves moved around the dance floor in intricate patterns and mutual rhythm. It didn’t take long before other ponies began to congregate around them in pairs, inspired by the sibling’s bold moves and fiery spirit.

The speed of their dance increased and Twilight felt her thoughts begin to scramble in the swirl of colors around her, the movement of her hooves more reflex than conscious. She closed her eyes, letting Shining lead her. Everything felt like in a dream and she would have perhaps even convinced herself that there was no way she was experiencing all of that for real if not for the warmth of her brother’s body surrounding her. In her dreams, even though he had been much closer to her, so close as her depraved imagination allowed, she could never actually experience him, feel how it would be to have their bodies touch one another.

Twilight couldn’t tell the moment when her lips puckered and her neck stretched out forward in hopes to overcome the last inches that separated her and her brother’s faces.

“What are you doing, sis?” Shining’s words were like a bucket of cold water thrown in her face. She opened her eyes instantly as her brain awoke from its slumber to take control of every and each muscle she could possibly possess. Failing at controlling everything at once, Twilight set her legs stumbling. She jumped away from her brother and smashed into the pair behind them, sending the three of them onto the floor.

Shining hurried to them with apologies and helped Twilight find her wobbling legs. He flung Twilight’s foreleg over his back and led the way back to their table, setting her on the chair carefully.

“Are you okay, Twily?” Shining’s voice sounded nervous.

Twilight put her hooves to her eyes and rubbed them in circles, wincing. “I need rest. That cocktail was too much for me.” The first part was true. Twilight did feel tired. Perhaps the second part was true as well. She couldn’t find any other explanation for the stupidity of her actions. What had she been thinking? Had she even been thinking? She had almost ruined the most perfect day in her entire life. She would never have forgiven herself for that.

Shining tried to rekindle their conversation as they made their way toward the train station. After the third attempt, with Twilight still staring silently at the ground before her, he gave up and continued to walk beside her without a further word.

In the train, Twilight closed her eyes and put her head on her brother’s shoulder, pretending to be asleep. She couldn’t fall asleep of course. Her head was buzzing with a thousand thoughts, her mind trying to replay every moment of her and Shining’s day together. After reaching the end, the point when she had almost set everything toppling down, she would rewind the tape in her head to start watching the footage over again.

The moon had taken its rightful place in the sky and Twilight’s castle lay in shadows by the time the siblings got back there. Twilight cringed as she pushed the doors open, expecting to see nothing less than a calamity after she had left her castle so unceremoniously. What she saw in there shocked her even more. Everything was clean and set back to their proper places. The whole castle looked like as if there had never been a gala in the first place. The only thing that was off was a chair in the center of the hall. Cadance was sitting on it, sipping wine from a glass in her hoof.

“You have good friends, Twilight,” Cadance said, yawning. “Didn’t leave this place until they made your crystal floors shine brighter than... well, crystals. Walls too.” She pointed to the far end. “Somepony spewed all over it when leaving your gala.”

Somepony’s vomit was the last worry on Twilight’s mind. “How are they? Have they been worrying about my sudden disappearance? And what of Celestia? Has she revoked my princess status yet?”

A laugh escaped Cadance. “You have nothing to worry about, Twilight. You’re not going to fall from Celestia’s favor because of such a trifle. You’re not the first one to run away with somepony from a boring party.” Her eyes settled on Shining, her grin widening. “As for your friends, they were about to run off scouring the whole Equestria the moment you disappeared. It took me some effort to convince them that you were perfectly fine.”

Twilight let out a sigh of relief. It was good knowing that nopony had to be worried because of her. Though quite how Cadance had figured out that Shining had been going to abduct her and teleport miles away, Twilight didn’t know. Was she the one who had given him the idea? Or was she simply reading her husband like an open book? In either way, Twilight was grateful to Cadance for handling her gala while she was having fun in another city.

“Thank you both for everything,” Twilight said. “But I’d better go to my room now. It’s been a very exhausting day.” She made to walk off.

“Good night, Twily,” Shining said behind her.

Twilight turned around and smiled. “Good night, BBBFF.” And she was gone.

Twilight tossed in her bed, attempting to hide from the image of her brother that was pursuing her thoughts with relentless ferocity. Even though he wasn’t with her now, she could still smell his scent on her fur. Even though her eyes were closed tight, she could still see his face etched onto the back of her eyelids. Even though the room lay in complete silence, his strong yet kind voice still rang inside of her head. Even though he wasn’t there to share his warmth, her body burned in fever, the heat between her thighs boiling away in the form of hot juices trickling down her hind legs.

Twilight threw herself to the other side of the bed and pulled the nightstand open. She took the replica of her brother’s cock and pushed it between her thighs to drive the heat away as she had done many nights before. It didn’t work now. The toy felt cold and crude and gross and Twilight loathed it with all her heart – a shallow copy of her brother’s body. She needed to see him. Real him. Just one glance at her brother would give her more to work with than a lifespan with the most accurate replica in the world. She threw the dildo back into the nightstand. Just one glance. Twilight assured herself. Nothing more. One glance would be enough to clop myself to sleep.

Casting her bed covers away, Twilight jumped onto the floor and hurried away to the hall. The darkness enveloped her the moment she left her room, keeping hold of her and making her heart race as she crept along the crystal corridor toward the chamber where Shining and Cadance stayed for the night. She didn’t dare light her horn to illuminate her path and instead felt the walls along the way with her hooves. It made her feel like a thief who had broken into another pony’s house to steal from them. The fact that it was her own home, along with the familiarity of its turns and twists didn’t do much to convince her otherwise.

Finally, the darkness gave way and Twilight saw a blue light shimmering around the entrance to the corridor that led to her brother’s bedroom. Twilight trudged along the blue aura with difficulty as if slogging through a swamp until she finally reached the end of the corridor and was mere steps away from her destination. She recognized the spell and remembered that she had been using a similar one to keep ponies away from her room while clopping. Unlike her version that blocked everything and everypony, Cadance’s spell was more intricate, scanning a pony’s body while they tried to walk through it and stopping them if they failed authorization. Cadance hadn’t been joking and had done everything possible to keep Twilight’s visit a secret. Twilight frowned at the thought, wondering whether Cadance was ready to go through all this trouble for a slim chance of her turning up here, or was her former foalsitter so confident in her prediction as to be sure that Twilight accepted her offer. In that case, Cadance was wrong. Twilight’s desires might have brought her to her brother’s door but that was it. She would never in her life cross it.

The door stood before Twilight, ajar with a slim beam of light emanating from the crack like a path to heaven, amplified ten folds by the darkness surrounding her. An indistinct chatter flowed from the room, beckoning Twilight to take a step closer. Her legs trembling, Twilight inclined forward and placed her eye against the crack.

Twilight gasped as her eyes adjusted to the bright light and the whole picture of what was going on in the room unrolled before her. Her brother was mounting Cadance, thrusting his hips back and forth with a relentless force. His hooves were wrapped around her back and barrel as his teeth nipped at her nape aggressively. The noise Twilight had taken for a chatter were ecstatic moans mixed with a wet sound of flesh slapping against flesh. Twilight’s legs gave up and she slid down onto the floor. She stuffed a hoof between her damp thighs.

Every idea on how sex might work that Twilight had derived from books and magazines withered away as she watched the carnal passion unfolding before her. Nothing could have prepared her to this. Twilight stared at her brother fucking his wife, mesmerized, her hoof rubbing her pussy relentlessly. Never in her life had Twilight’s attention been focused on a subject so unreservedly, not even during the most important of Celestia’s lessons. Despite the impossible speed of their fucking, Twilight was able to make out her brother’s cock sliding from the opening of Cadance’s pussy, the underside of his shaft brushing her feverishly winking clit. He pulled away briefly until only the head of his cock remained squeezed tightly by his wife’s dripping snatch only for his cock to be slammed back into the depths of her tunnel, making Cadance squeal with desire for more.

Oh, how she wished to be in Cadance’s place. Be the one who was begging for her brother’s cock to be rammed into her. Twilight pressed a hoof against her pussy harder and flicked her clit up. It didn’t take long before she began to do what she had mastered to perfection over all those years – imagine her being in her brother’s wife’s place.

“So, how was your day out with Twilight?” Cadance managed through a moan. On the other side of the door, Twilight was being too occupied trying to conceal her own moans as to pay the budding discussion any real attention.

“It wasn’t that bad,” Shining hissed through gritted teeth as he pushed into Cadance, a wet squelching sound almost swallowing his words. “But I think she’s still somewhat angry at me. Though I don’t understand what I’ve done wrong.” Another powerful thrust driving Cadance’s face into the cushion.

“Give her time.” Cadance bit her lip but a moan nonetheless escaped her. “I’m sure she’s thinking about how to mend up your relationships right now.”

“I hope she does. I’ve run out of ideas on how to approach her. I wish she just told me what’s gnawing at her heart.” A dull sound ran through the room as Shining’s hoof slapped Cadance’s flank unceremoniously.

“And what about that Starlight pony?” Cadance muttered, her head buried in the pillow. “I saw you two drinking a cocktail together. Did you like her?”

“Why would I? She has nothing to offer me that you don’t have, honey.”

“Sure.” Cadance moaned into the pillow as her winking clit brushed against the flat tip of Shining’s cock. “And now the truth, dear.”

“Well, it was very cute watching her try to seduce me. She was very cute.”

“But you didn’t give her any attention, right?” Cadance’s horn glowed and she fumbled her husband’s balls with her magic.

“Of course not. You’re the only mare who holds all my attention, honey.” Shining thrust his hips into Cadance’s spasming pussy with a ferocity to emphasize his point.

“Good.” Cadance’s clit winked once again and more of her juices began to trickle down her thighs.

“Cadance... I think I’m about to cum.” Shining’s breath became rapid as the rhythm of his pumping increased.

“Just make sure to pull out. I am in season.”

“Are you sure you don’t want another foal?” A hint of sadness spoiled Shining’s blissful expression.

“Don’t even start on that. It took me a whole day to find a pony oblivious enough as to agree to foalsit Flurry Heart while we’re away here.” Cadance bit her lip and moaned in delight before continuing. “I don’t have another twenty-four hours in my day for another foal.”

Shining didn’t answer and instead drove himself into his wife to the hilt with a guttural groan, then drew back and pulled his cock out of his wife completely. The head of his cock flared and a gush of thick cum burst out from it, landing on Cadance’s back, flanks, and tail, painting her body in snow-white.

After a moment of post-orgasm panting, Shining wiped the sweat off his forehead and said, “I wouldn’t mind having another foal though. A colt. Playing hoofball with him. Watching wrestling together. Perhaps one day he would follow family tradition and join the military. Like me and my father and his father.”

Cadance climbed off the bed and kissed Shining on the lips. “Maybe when Flurry’s grown up I might think about it.”

Shining looked at his wife gloomily, sighing.

“Don’t be sad, dear,” Cadance said, a smile forming on her face. “I know how to lighten your mood up. Because you were a good boy today, I have a present for you. But it’s a surprise.”

Cadance drew out a blindfold and waved it before her husband. She propped Shining upright against the bed’s headboard and put the blindfold on him.

“Cadance, you know I don’t like surprises that much,” Shining complained.

Cadance rolled her eyes. “Fine, I can tell you, I guess. I was talking to Starlight and she confessed to me that she finds you very attractive. So I decided that it wouldn’t hurt if she joined us today for a little bit of fun.”

“Wow, really?” Shining reached out to take off his blindfold but Cadance stopped him.

“Really. But you are to keep this. As you might have noticed, Starlight is a very shy pony when it comes to the opposite sex and she has never lain with a stallion before. She is very, very self-conscious about herself. It was her wish to have you wear a blindfold.”

“Well, it’s kinkier than usual but I hardly can say no to a good threesome, can I? Is she waiting behind the door? I’m sure I heard a wet sloppy noise coming from there. I guess she started the fun even before hitting the bed.” A laugh escaped Shining.

It was only when Cadance opened the door with her magic did Twilight’s mind catch up with the conversation that had just happened. She began to spin her head around rapidly, expecting the condemning eyes of Starlight staring down on her sprawled form but there was nopony behind her but the thick darkness.

Twilight jumped back in shock as a hoof grabbed her foreleg. She turned around and sighed with relief. It was just Cadance. The Princess of Love had already known everything about her. Of course, she would never invite both her and Starlight at the same time after having sworn it to be a secret between them.

Cadance helped Twilight to her hooves, trying her best to ignore a viscous puddle of Twilight’s juices spreading across the floor that she had accidentally stepped on. She tugged Twilight to get her inside but Twilight pulled back hard. “Are you going to come in, Starlight?” Cadance asked.

Twilight wanted to say ‘No, I’m not’ but shoved a hoof into her mouth just in time to prevent herself from spilling the words out and allowing her brother to recognize her by her voice. Even while horny as hell, hornier than she’d ever been in her entire life, the fear helped the gears in her head keep going. Was she really going to sacrifice everything she had and loved for a mere night of carnal pleasure? No, she wasn’t. She was Twilight Sparkle. The representative of magic. Celestia’s personal student and a Princess of Equestria. Not a wanton slut from the slums who could not control herself. She shuffled her hooves around and started to her room, her eyes seeing off Shining’s sitting form. She’d promised herself just one peak and had more than enough of them for the rest of her life.

“Is something wrong, Starlight?” Shining asked, stretching on the bed. “Don’t be afraid of me after you’ve already come all the way here. I won’t bite.” He laughed. “If you don’t want me to.”

Terror seized Twilight as the realization dawned upon her. If she did nothing and just ran away her brother would go after Starlight, real Starlight, and ask what had gone wrong. Starlight would say she had no idea what he was talking about and take it as an affront to her honor. And this would be the least of Twilight’s worries. Then her brother would deduce that it should be another pony who’d been there and the only pony he would be able to choose from would be her! Twilight Sparkle. His own sister, stalking his bedroom at night to watch him have sex with his wife. He would think of her as a crazy freak and never talk to her again. Twilight’s teeth chattered. The only way out of this situation was to continue to play Starlight. Hesitantly, Twilight turned around and allowed Cadance to lead her into the room.

Twilight was making every step with tentative care as if afraid that her brother could recognize her by the sound of her hoofsteps and be scared away. She approached him like the most precious treasure in the world. And what the gems that treasure held! Twilight’s eyes were fixed on her brother’s massive balls, taking in every little spot and crease. Even his cock, though spent, was a scene to behold, lying on her brother’s belly, twitching slightly, eager to be raised to its glory once again. Twilight’s pussy spasmed, forcing her clit to peek from her labia, declaring to the world how hungry she was for her brother’s thick cock. As if a hungry look in her eyes wasn’t enough.

“His face is a little bit higher,” Cadance said, smiling. “Why not get to know each other better before jumping on him?”

Twilight’s cheeks flushed with crimson. Even though her subconscious tried to avoid any eye contact with Shining, it was time to let those fears go after she had gone so far. If she was going to have sex with him, it would be with her brother, not a faceless piece of meat looking like him.

Taking a deep sigh, she let her eyes travel along her brother’s body, up his belly, his chest, all the way up until she met... Twilight almost forgot that her brother’s eyes were hidden under the blindfold. Of course, they were. And what they were seeing through it was another mare, not his own perverted sister. A sudden impulse made Twilight want to rip off that piece of fabric that separated them. She made a mental attempt to move her hoof but her body didn’t listen to her. An image of what those eyes would reveal to her after she had pulled off that blindfold paralyzed her every muscle. His smile is enough. It is more than I have ever had.

Twilight sat down on the edge of the bed, her every limb trembling. It took help from Cadance to have Twilight straddle Shining’s lap. She gasped as her sensitive lips brushed against the medial ring of her brother’s cock that was now squeezed between her tits and his abdomen. She pressed her hind legs around her brother’s sides tightly and couldn’t help but fidget as her brother’s cock continued to stiffen under her, now rubbing against her winking clit. She didn’t have the strength to keep her back straight and fell down on her brother’s chest, their faces mere inches away from each other, their hot breaths intertwining.

“Well, what are you waiting for? Kiss him,” Cadance said from nearby, her tone reminding Twilight of the instructions Celestia would issue when she needed her students’ special attention.

Taking a deep breath, Twilight nodded to herself. That was it. Her first real kiss. With a real pony. No, she amended herself. With her brother. And this time she wasn’t going to flinch away. Her heart pounding in her chest like a drum, Twilight puckered her lips and forced her head forward, surmounting the last inch that separated her and her brother. As their lips met, a jolt of realization hit her chest. She didn’t know how to kiss! She desperately tried to remember everything, something she’d read about the matter in the books but nothing coherent came out of this. She moved her lips awkwardly like a fish suddenly plucked from the water, her eyes wide with panic. That was when her brother’s strong tongue pushed its way through her teeth and she closed her eyes tight as Shining began to caress and explore her mouth. His lips pushed against hers like a silky soft brush, his teeth grazing against her gently.

When Twilight thought that the moment of their union couldn’t feel even better, her brother grabbed her asscheeks tightly and began to massage them in circles while still caressing the insides of Twilight’s mouth. Twilight melted away in her brother’s embrace completely and gave up any initiative she had, letting him explore her body in fullness. His hips moved back and forth, rubbing his cock between her tits and brushing the bottom of her vulva, soaking his length in her juices. He dared slide his right hoof deeper between Twilight’s asscheeks and, after she didn’t give any sign of objection, he fondled her puffy butthole with the tip of his hoof.

Shining’s other hoof began its slow journey up Twilight’s slim body, exploring her feminine curves, sliding up her supple ass to her lower back, almost touching her wings... Twilight’s eyes opened wide with shock and she would have jumped from her brother to another side of the room if not for another hoof that stopped Shining’s advance.

“I think it’s enough for now,” Cadance said. “Don’t want our guest to hyperventilate here. Look at her, I think she forgot how to breathe.”

It was true. Now that Cadance had mentioned it, Twilight lifted her lips from Shining’s and began to rapidly pump the air back in her body, shaking with both fear and excitement after everything that had just happened.

It took Twilight some time to realize that something in Shining’s expression was off, his forehead creasing in confusion. Cadance had noticed it too.

“Is something wrong, dear?” The Princess of Love asked.

“No, nothing,” Shining said, his confused voice at odds with a composed demeanor he tried to put on. “It’s just... It’s just that she smells like... Twilight.”

Twilight heart skipped a beat and she hurried to cover her face with her hooves as if expecting the whole world crumbling down upon her.

“Of course she does,” Cadance said calmly. “You see, Starlight really suffers because of her past and is in need of a worth pony to look up to. Like Twilight. She’s trying to simulate her in every detail and of course it’s no wonder she would go as far as to use a perfume to imitate Twilight’s scent. In fact, her biggest request when we were talking about the night was to have you call her Twilight while fucking her.”

Twilight and Shining’s mouths fell agape in unison.

“What?” Shining sounded outraged. “You can’t be serious.”

“Is something wrong with that, dear?” Cadance’s grin broadened. “You were already thinking about your sister while kissing our guest here. Nothing really changes. Your head was already full of your sister’s scent. The memories of you and her at the time of your foalhood were bubbling up at the back of your mind and you imagined your sister was the one whose ass you fondled with your hooves.”

“I didn’t!” Shining protested. “It’s just... It was all too fast. Perhaps a thought crossed my mind once but it was just in the heat of a moment. I would never touch my little Twily that way in real life.”

Twilight’s heart sank at her brother’s words. Though what had she even hoped for? There was nothing new in those words, really. She had already known everything about her brother’s feelings to her for her entire life.

“Oh, don’t make me punish you, dear.” Cadance shook her head, her eyes narrowing. “You know very well I can’t stand lies in my bed. If you want, we will put an end to this little game in an instant. But first, I need to hear your sincere answer to my question. Don’t try lying. You know I read you like an open book when you try to hide something from me in bed.”

“Fine,” Shining said, puffing the air out of his mouth, the right corner of his lip curling up, indicating his irritation. “Whatever.”

“So my question is,” Cadance became slowly. “Have you ever in your life thought of the delicious curves of your sister’s purple plump ass? All the while imagining how good your cock would fit inside her warm welcoming embrace after you have mounted her. How loud she would cry your name, begging for you to thrust your cock deeper and deeper into her, proving your sister how much you really love her.”

Twilight felt Shining’s cock stiffen under her, his shaft throbbing, rubbing against the opening to her pussy with a renewed force. She herself also could tell that her clit quickened its winking, begging for the cock Cadance had just mentioned.

Shining’s cheeks glowed with red as he opened his mouth to speak. Then closed it. Then opened and closed again. Until at last, he gathered enough courage to speak his mind.

“Maybe it’s been a few times. Well, maybe more than a few times...” He let out a defeated sigh. “Fine, you won. I will be playing your game. But don’t either of you think that I really want to fuck my little sister. And it will be better if we all forgive everything about this night after it’s finished. My little Twily is too naive and pure to even imagine the scope of this depravity. She is to know nothing about it. That’s my condition.”

“Of course, nopony but us three here will ever know about this night,” Cadance said, both grinning like a mad genius and seeming to be offended at the same time. “Keeping things private was the first thing I taught our guest here. She of all ponies has the fewest reasons to blurt anything out.”

Cadance tousled Twilight’s mane playfully like she had done many times when she’d been foalsitting her and favored Twilight with a warm smile. Twilight smiled back, glowing with happiness. Her brother had been thinking of her! Not just as a sister but a mare. A mare he was thinking to have sex with. Even if it had been just a handful of times at the back of his mind.

Twilight couldn’t remember when she felt so happy in her life. Even when graduating from Celestia’s school for gifted unicorns she had been feeling a bit sad because of the separation with her mentor. But this? What Twilight felt right now was the definition of the word ‘happiness’ according to any dictionary. Every fiber in her body was filling with boundless energy. The night itself seemed to fade away and let light be shed on her head, every her doubt gone. She knew what she had to do. Never in her life had she been so sure in her decision as she was right now. She was going to make him regret. Make him curse himself for every chance to fuck her he had missed. She was going to make him be the one begging for her.

Twilight jumped off her brother’s lap and slid back until her rump lay inches away from the edge of the bed and her muzzle inches away from her brother’s throbbing erection. She took Shining’s cock in her hooves and rubbed it against her cheek tenderly. The sensation of having her brother’s stallionhood brushing against her face was even better than she had dreamed of. Even the replica she had painstakingly crafted paled in comparison. Though something felt a little bit off as she continued to probe Shining’s cock. The medial ring was half an inch higher than she was used to knowing! Had she messed up the proportions of the replica or had Shining grown up since her last measurements? Twilight horn glowed and a purple aura enveloped the entirety of her brother’s length, exploring every inch of it. He had grown up. Twilight made a mental note to update her equations and prepared for deep research of her brother’s body.

She stuck her tongue out and probed Shining’s pee hole, gently swirling her tongue around the tip. A sour-sweet tang of Cadance’s juices washed over her taste buds, rivaling with her brother’s more pungent musk. She found herself liking the mix. Cadance’s aroma was somewhat softer and sweeter than her own lavender flavor and she imagined her brother’s cock slathered in a thick candy syrup while giving him a long lick over the glans.

Shining’s cock made a throb, letting out a droplet of cum left from his previous orgasm. Twilight lapped up Shining’s gift eagerly, savoring her brother’s real taste for the first time in her life. He tasted just as good as she had imagined, his viral odor making her crave for more. She clenched her hind legs subconsciously, her clit winking, as she finally sent her brother’s nectar down her throat.

She enveloped her brother’s cock with her hooves and began to stroke the length as her tongue explored more and more of Shining’s wide flare. Her ears lifted up excitedly as she heard a first moan escape her brother’s lips. Her brother was feeling good because of her! Twilight could barely hold back the thrill rising up inside her and pushed her muzzle into her brother’s scrotum to muffle the squeak of excitement. She rubbed herself against each of her brother’s plump balls happily, took a deep breath of his scent and began to slowly trail her tongue all the way upwards, slobbering excessively and adding her saliva to the mix of her and Cadance’s juices. Slick as her brother’s cock already was, Twilight’s countless lessons had taught her that it was crucial to make the cock as slippery as possible for what she was about to perform.

“You are very good at sucking your brother’s cock, Twilight,” Cadance said, her hoof sliding down between her hind legs, emphasizing her point. “Very good.” The Princess of Love’s face contorted with pleasure as she began to rub her pussy.

A smirk spread across Twilight’s face as she eased her brother’s cock into her mouth and began to suck on it tenderly, her tongue swirling around the circumference of his glans. Oh, I’m just getting started.

How many times had she imagined this situation before her, producing it in her mind with the help of the dildo she had specifically made to practice with? Twilight had lost count long ago. All of those long nights, the exhaustive training of her throat she had almost given up once. It seemed like her whole life converged to this very moment. It was her chance to show her brother that she was ready to do anything for him. Show him that her love to him was infinite, having neither a limit nor a base.

Twilight closed her eyes and relaxed every muscle she had, getting into the meditation she had taught herself while practicing on the replica of Shining’s cock. The inner working of her body slowed and her breaths became spare, just enough to support the vital organs while putting the rest to dormancy.

Twilight put her hooves down on the bed by either side of Shining’s hips, holding her brother’s cock by the tip with only her mouth. She pushed her head slightly down, massaging the entrance to her throat with the cock’s glans and pressing it further but not quite gulping the tip down yet. A few more bobs over her brother’s cock and with a big final breath, she plunged in.

Neither Cadance nor Shining was prepared for what happened next. The tip of Shining’s cock plopped into Twilight’s throat without delay and the force with which Twilight threw herself on him carried her all the way down until her muzzle landed on the fluff of Shining’s groin. Twilight made a gurgling sound as she tried to make herself comfortable between her brothers’ hind legs. A stream of saliva was leaking from her outstretched mouth, dripping off on her brother’s balls. Twilight’s neck bulged outward just enough for her brother’s cock to be completely enveloped in the velvet warmness of her tight throat. He fit her perfectly and she basked in the sensation of having every corner of her throat filled and stretched with her brother’s thick cock. They were now connected not just by blood and memories, but as entirely as two ponies loving each other possibly could.

“Starlight...” Shining uttered through gritted teeth, his hooves wrapped in the bed sheets, clenching them in two tight knots. “Fuck it. Twily, you are incredible.”

Twilight smiled around her brother’s cock. She knew he would love it. And it was only the beginning.

It took Shining a while to come back to his senses after an incredible wave of sensations that had surged through him in a mere moment. His breathing returned to a steady rhythm and he finally let go of the bed sheets to fumble around his groin with his hooves. Obviously not finding his cock, he brushed Twilight’s inflated cheeks. He continued to trail his hooves up her head as if unable to believe that somepony could swallow down a cock so expertly. He touched her horn and petted her head. It wasn’t some trick. It was a real pony. And she was still there. Her lips were brushing his balls while his cock was buried deep inside her throat.

“Honey, are you sure she’s never had a stallion before?” Each of Shining’s words left his mouth as a moan, his hoof continuing to pet Twilight’s head affectionately.

“I’m quite sure, dear,” Cadance said, her eyes wide, a hoof between her hind legs now rubbing against her wet slit with incredible speed. “It seems she’s been training a lot.”

Despite the enormous girth of her brother’s cock, Twilight’s cocky smile grew even so. She decided that it was the perfect time to show off her real talents.

She lifted her head off Shining’s cock until only the tip remained tucked snugly around the entrance to her throat. She then dived back in, gobbling up her brother’s entire length in one go, her throat stretching and tightening at once to massage him. A gurgling sound escaped her lips as she reached his groin, more wet squelches following as she raised her head, releasing most of her brother’s cock only to dive in again a moment later. She found a steady rhythm of fucking her brother’s cock with her throat and just enjoyed the feeling of his great girth inside of her, filling and stretching her. Trickles of drool flowed from her mouth as his virile scent overwhelmed her senses.

Shining’s hooves wrapped around Twilight’s head firmly as he tried to follow the rapid bobbing of her head. “Twily, I’m cumming!” A guttural sound escaped him. “Drink it all down.”

Twilight’d never heard her brother sound so savagely like this before. With some force, he shoved her head along his cock all the way back down to his crotch, holding her in place there. Shining’s cock gave out the last powerful twitch inside of her and his tip flared, extending Twilight’s neck outward to its limit. A gush of thick hot cum rushed into her stomach.

Twilight had been ready for this moment almost her entire life and let her throat milk her brother’s cock completely, gulping his gift down her gullet. What she wasn’t ready for was the sheer intensity of her brother’s orgasm. Twilight began to doubt her ability to handle her brother properly after the fourth jet of cum hit the back of her overflowed throat with the same ferocity as the first three squirts, if not even stronger. The fifth and sixth sprays of his thick cum splashing inside her only confirmed her fear. She couldn’t keep up with the enormous amount of passion her brother was offering her. Her throat and nasal canal were stuffed to the brim quickly and though she tried to slurp everything down, more and more of her brother’s cum was leaking out of her nose and the corners of her mouth, mixing with her saliva and bubbling down her chin.

At one point there was so much cum flooding her that for a moment Twilight thought she might drown in it. The last of the oxygen in her lungs was gone and Twilight’s primal instincts kicked in, crying at her to take out the foreign object from her throat right now. She lit her horn purple to cast herself away from her brother’s tight grip on her head but he let go of her just in time and Twilight lifted herself up, expelling all her brother’s length from her mouth in one pull. Shining’s cock sprang up and the last gush of his thick cum drew an arc in the air before landing on Twilight’s cheeks, horn, and splashing down her mane.

Twilight gulped in a lungful of air through her burning lungs and began to wheeze, coughing her brother’s cum out of her overstuffed nose and throat, milky tears running down her cheeks.

“Fuck. That was the best head in my entire life,” Shining announced blissfully, his head thrown back in ecstasy. He stretched his limbs and smiled. “I love you so much, sis.”

Twilight reached up with a hoof and wiped away a tear, this time the one of happiness. “I love you too, BBBFF.” She shut her mouth with both hooves, wincing, but it was too late.

The longest moment in Twilight’s life followed. Both she and Shining armor sat entirely still, forgetting to breathe.

“I guess, there’s no point in games anymore.” Cadance pulled a soaked hoof from between her hind legs and stretched it out to her husband’s face, lifting up his blindfold.

Shining’s eyes went wide in shock the moment they got their freedom. “Twilight? Is it really you?” It was definitely her. It was his little sister. With his cum dripping off her nose and chin.

“I’m sorry. I’m so sorry.” Twilight closed her eyes and threw herself at her brother’s chest, wrapping her hooves around him tightly. “Please don’t hate me. Please don’t hate me.” She began to mutter, her stuffed with cum nose making it ever more incoherent.

If it was the last moment with her brother she would ever have, she wanted to prolong it as much as possible, feel the warmth of his body against her, remember his heartbeat, his scent. Twilight squeezed her forelegs around Shining with a renewed force, awaiting a push that would drive her away but instead she felt her brother’s hooves settle tenderly on her back.

“Don’t be silly, Twilight. I will never hate you.” He hugged her back, more tightly than he had ever before. “I love you. I will always love you.”

“So cute,” Cadance said. She put her hooves together before her chest and clapped them lovingly. “Twilight, I told you that you had nothing to worry about.”

A snarl showed on Shining’s face as he turned to face his wife. “Cadance, this time your games have gone too far. If you were thinking that after bringing Twilight here I’ll let it go, then you don’t know me at all.”

Cadance opened her mouth to speak but Twilight broke in with a cry. “Cadance has nothing to do with this! I came here by myself. You were always more to me than just a brother. I’ve been fantasizing about you and me having sex since I discovered what masturbation was. You are the only pony that kindles fire in my heart and loins. You are my special pony I can’t stop thinking about. You are my world and there’s no place for me to live without you.”

Cadance had been right. It felt good letting out all that weight that had for so long tore her heart apart. No matter what her brother’s answer would be, it felt good.

“I didn’t know...” Shining muttered. “I’m sorry that I’ve never noticed your feelings. I was a really bad brother, wasn’t I? But I’m going to make up for it. I promise you.” Shining placed a hoof under her sister’s chin. He lifted her head up and looked her in the eyes. “Will you have sex with me, Twily?”

“Do you really mean it?” Twilight could barely keep herself from exploding into tears. She had been dreaming about those simple words for so many years. Everything around her felt surreal and it was only because of her brother’s warmth that encircled her, that she could tell this time it wasn’t a dream.

Instead of answering, Shining Armor grabbed Twilight’s ass with his hooves and with a little help of his magic moved her backward and upward until her dripping pussy was lined up with the tip of his throbbing erection.

Twilight let out a whimper of pleasure as her lower lips parted to swallow her brother’s cock down her spasming tunnel, the sensation somewhat familiar and yet thousands times brighter than the piece of silicone she had been forced to substitute her brother’s cock with for so long. Familiar with Shining’s contour, Twilight’s pussy tightened around her brother’s cock perfectly, feeling his every vein as the shaft slid deeper inside of her.

“Congratulations, Twilight!” Cadance said beside the pair, watching the place of their connection closely. “You’re officially not a virgin anymore.”

Shining body's stiffened as he heard her wife’s voice, having seemingly forgotten that she was there. “Honey, I hope you’re not—”

“Relax,” Cadance said, poking her husband’s nose playfully. “I don’t envy. Almost. You can fuck Twilight as much as you want. Though it doesn’t mean I allow you to neglect me.”

Cadance lifted her flanks off the bed and, leaving a trail of her juices dripping on the bed, turned around to place her pink plump ass on her husband’s face. She made Shining lie on his back and aimed her sopping slit right down under his eager tongue, fixing his head in place with her hind legs and leaning against his chest with her forelegs for a better balance. “You better have your tongue ready, dear,” She said and pushed her asscheeks down, completely muffling any objections he could have had.

“Cadance, your Cutie Mark. It glows!” Twilight managed through a moan, her lips curling in bewilderment. Below her, her brother thrust his hips hard into her, spreading her pussy with his generous girth while licking his wife’s lips and clit hungrily.

Cadance looked down the crystal heart etched onto her flanks that were now gleaming brightly. “Ah. That?” She let out a moan as Shining forced his tongue into her slit and began to explore it thoroughly, a rivulet of Cadance’s juices trickling down his chin. “They always do this when I bring together two ponies who love each other. Though it’s the first time one of those ponies happens to be my husband and another one his little sister.” A grin showed on her face.

Twilight inclined forward and hugged Cadance with gratitude. She would never forget what Cadance had done for her. “Thank you,” she whispered.

“Don’t bother yourself with that.” Cadance returned the hug, wrapping her hooves around Twilight tenderly. “Shining has already always loved you. All I’ve done is give a little prod.” Cadance smiled, winking.

Twilight smiled back. With Shining’s hooves sunk into the flesh of her ass, she lifted herself from him slightly and then fell back onto his groin, feeling the entirety of him inside her once again and finding a perfect rhythm to riding her brother’s cock.

Meanwhile, Cadance’s face contorted in orgasm as her pussy contracted around Shining’s tongue, and all the pressure that had for so long been compressed inside of her flowed out, her viscous juices flooding her husband’s mouth. Shining hurried to gulp everything down while still remembering to suck on Cadance’s winking clit tenderly.

After Cadance’s orgasmic twitches subsided, she climbed off Shining’s face on her still trembling legs and patted her husband’s head. “Good boy,” she cooed. “Now be a good brother and make your sister cum as much as you have me.”

Cadance lay down on her belly and slid closer to the place where Twilight and Shining were connected. She stuck out her tongue and whipped the base of Shining’s cock with it, swirling around Twilight’s clit every time she descended on her brother’s groin. With a squelch sound, a spurt of Twilight’s juices escaped through the tiny gaps between her pussy and her brother’s cock and landed on Cadance’s waiting tongue. The Princess of Love licked her lips lustfully, swallowed down and continued to stroke the base of Shining’s cock with her tongue.

It proved too much for Shining and he squeezed his eyes, groaning. “I’m cumming, Twily. Get up off me or you might get pregnant.” He managed through a moan.

Twilight moved her hips even faster, slamming herself against her brother and kissing his groin with her pussy lips affectionately. She could feel the heat inside her was about to burst. “I know I might and I want it. I want your foal inside of me,” she muttered with her head full of pleasure, her pussy contracting around her brother’s cock greedily. “Please, Shining, you’ll make me the happiest mare in the world—”

Twilight broke off with a gasp as an orgasm hit her. She squeezed her brother’s cock with all the force she had, intending to milk his precious cum inside her.

“Fuck! I love you so much, Twily.” Shining groaned animalistically and thrust his hips upward into his sister’s depths with all the force he had, hitting her cervix and plugging it, making sure that none of his cum could escape from her. His flare widened and a gush of his hot cum rushed into Twilight’s womb, filling it to the brim.

The siblings panted in unison, their eyes fixed on one another. Neither of them wanted to break their deep bond. Alas, nothing lasts forever and Shining’s spent cock began to deflate and slide out of her. Twilight let out a little whine as she felt the emptiness inside of her return once more. Though this time everything was different. Even after her brother’s cock plopped out of her completely, she could still feel his warmth deep inside her, his seed rushing to her ovaries to fertilize her. At that moment Twilight knew that she would never ever have to feel lonely again.

“Thank you, Shiny,” Twilight whispered, rubbing her belly tenderly. “I promise I’ll raise the foal so that you will be proud of him.”

“Him?” Shining asked, puzzled.

“Somehow I know it’ll be a colt.”

A ringing sound ran through the room, turning Twilight’s attention to the clock on the wall. It was already midnight. Her birthday had just passed. When Celestia had asked her to throw a birthday gala, Twilight had known that many things could have happened during that day. But she could never have imagined that her life might have changed so drastically in one day. However, it was time to return to her routine. After a good night of sleep, the world, as she knew it, would still continue to drag along its mundane path, regarding the fundamental changes of her life as nothing but another grain of sand in the unending desert. Everypony expected her to behave as if nothing had happened. Pinkie Pie was still waiting for her to throw a real birthday party in her circle of friends. And she still definitely had her responsibilities as The Princess of Friendship. Cadance had provided her with enough material to work with for months ahead.

Twilight made to get off the bed but her right hoof got caught in Shining’s grip and her left hoof in Cadance’s. “Stay,” they said together.

Twilight stayed. The lights were shut off and the three ponies fell asleep, cuddling up against each other.

Tomorrow’s world might wait. Right now she was with her brother and her best friend, and that were the only things that mattered.
