Part of Twilight’s job, besides spreading friendship and preserving harmony, was satisfying her rabid curiosity. Sadly for her, most of her ideas were haphazard, rabid and wild, unfit to be brought up in a study at all. Sadly for everyone else, though, she studied them anyway.

Now, she was slaving over books, as she normally did, tiredly flipping through pages in an attempt to fill the void her last adventure had left in her. She was searching for a spell that did anything interesting, really. Nothing too complex, and one that wrapped itself up nicely. But, she’d been sitting here, reading without much to show for it.

She sat back and placed her front hooves behind her, allowing Starlight some leeway. She didn’t want to choke the poor mare. Starlight pulled back slowly and released Twilight’s cock from her mouth with a small pop. It was covered in her saliva now, and a steady stream of pre was steadily flowing from the tip.

“T-that was amazing…” Her body shook as she struggled to regain her breath. Twilight smiled. Seeing her student lust over something only she could provide her pleased her greatly. “Can we c-continue?” Twilight pressed a hoof to her slick shaft, stringing some saliva along when she brought it back.

Twilight stood up on her hooves, now looking down at her student. Starlight’s eyes couldn’t stop following her meaty cock dangling between her legs. She scrambled around, pushing her face into the floor and jutting her flank up at Twilight. Her tail swished from side to side excitedly until she pulled it out of the way entirely, revealing her plump cunt completely. Twilight looked down at her before nudging her winking clit with a hoof.

“Wow, Starly. You’re basically drooling.” She pulled her lips apart, a slow dribble of her juices as they crawled down her legs. The wet pink closed and contracted, little strings of her marecum sticking to the walls. Twilight lined herself up properly and prodded her insides gently. “Does this excite you that much?”

“Y-Yes…” She could barely hold herself back, almost thrusting herself back just to give herself pleasure. Twilight chuckled a bit, teasing her even more. She placed her shaft against her clit and rubbed it up and down. She could tell it drove Starlight crazy. She shook and shuddered under Twilight, whimpers of disappointment escaping her every time Twilight thrust. “Please, Twi. I-I want this so bad.”

“Well now,” she pulled back and began prodding her asshole. Her tail tickled her tip, and her clit winked in excitement. “That’s not how you should ask for something, now is it?”

“Twilight, I—” she breathed hard and she tried to keep herself in check. “Please, I can’t wait this long.” Twilight rubbed her hoof against her clit slowly, soaking her hoof in her juices and watching them stream down her thighs. She licked her hoof, tasting the salty wetness on it.

“Let’s see…” Starlight’s pussy swallowed the head, and Starlight herself let out a quiet sound of satisfaction. Her insides hungrily grabbed for more, but Twilight stayed as she was. “If you cum first, you have to do one thing for me, and if I come first, I’ll do any one thing for you.”

“Y-Yes!” She said without hesitation. “I’ll do anything to have this in me, now!”

She lined herself back up and thrust forward slowly, pulling a shriek from Starlight’s lips, and filling her entire cunt with meat. She bit down to keep herself from yelling out again. Twilight was sure she was going to, anyway.

She started slowly, pulling out nearly fully before stuffing her again. Every ram squelched her insides, getting into a good rhythm and scratching the itch for dick her womb desired. Her juices were dripping to the floor now, making small pools on the ground.

“You’re already this wet,” said Twilight, pushing her girth in fully. “Are you sure you haven’t cum already?”

“No! I-I didn’t, I swear!” Twilight pulled out completely, letting Starlight dribble out onto the floor before turning her onto her back. Her face was plastered with red, and she was breathing hard. “Please don’t stop… keep going.”

“No one said anything about stopping, now did they?” She lined herself up with Starlight and stuffed her again. Starlight gasped, quieter than before. Her cock mingled with her womb, rubbing against it and sending pleasure pulsating up her body. “I don’t think I could stop myself, now.”

After switching positions, Twilight became more feral, animalistic. Her long thrusts were replaced with quick pumps that all but attacked Starlight’s womb. It shuddered under the constant barrage of cock slamming against it, and Starlight followed suit. She devolved from being a mare to a mess, only working to bring the dick inside of her closer to orgasm.

And with every plunge, Twilight got closer and closer. Starlight’s womb was sucking against her tip, giving her a slight bit of resistance as she tried to pull out. Twilight looked down at her student, her mind almost completely taken over by the thought of cock and knew that this was truly a perfect pussy.

Twilight’s balls clenched, she pushed in one last time before lathering her womb with a thick, hot, and creamy sauce. The cum covered her shaft on the way out and escaped with a quiet bubbling sound. It dribbled down both Starlight and Twilight’s legs. She pulled out and slapped her cock on top of Starlight’s chest, shooting that last few globs of cum right onto her face. From what Twilight could see, she was lost to ecstasy long before Twilight thought of getting off of her.

“Looks like you had a good time, hm?” said Twilight. Starlight’s leg twitched, her tongue lolled out of her mouth and she was breathing heavily. She nodded, blushing and covering her face with her hooves. “Well, it’s not over. You owe me a favor, now.” Twilight sat back and poked a hoof into the cum that had lined her tip and licked it off. Starlight needed no more instruction, crawling over and beginning to clean up the mess. “Thanks, Starlight. Nothing gets the juices flowing like a good distraction.Now, it’s back to work?”

The morning was almost normal for Twilight.

She woke up, normally, as always, with her hair frazzled and her coat frizzy. She would need to brush those later. She was under her cover, warm, despite the cold in her room. Best of all, she was snuggling her best friend, Smarty Pants closely in her arms.

The “almost” part came in when she opened her eyes.

“Good Morning.” Twilight could understand things it would take a full-grown mare years to do, and cast spells that scholars could only scratch their head at, all as a foal. Still, she couldn’t fully wrap her head around why there was another her.

Older Twilight could, though. She waved her hoof at the bewildered foal before her, who was technically herself. The magic that led to this moment was complicated, with layer upon layer of complex enchantments over each other, but with a bit more time, Twilight suspected that even her younger self could practice it.

“I… I-I, what?” Twily stumbled over her words, but Twilight simply smiled back. “What kind of magic is this? Is this real?” She reached out and touched Twilight’s face.

“I’m really here, yes,” said Twilight, running her hoof through Twily’s mane. The situation was surreal for Twilight. Twily cowered at her touch, but eventually softened up. “I’m here for a specific purpose.”

“Why are you here?” she asked. “How are you here? This is definitely going to require study.”

“I can do magic the likes of which you’ve never even dreamed of,” said Twilight. Twily’s eyes sparkled magnificently, easily caught like a swindler glimpsing at a bit. “And I’ve studied all of it for a long time. So, I’m going to teach you what I can so you can be even better.” Twily nodded wildly.

“Teach me, please! I want to go back in time!” Twily bounced on her bed, almost jumping onto her older self. Twilight chuckled and backed up.

“Well first, you need to promise me something.” Twilight used her magic to quietly turn the lock on her door. “You can’t tell anypony what I’ve given you. It might ruin the future if you do.” Watching her younger self cling to every word she said was astonishing, not to mention arousing. She bit her lip a bit to keep herself under control. She couldn’t spoil the surprise just yet.

“I won’t tell anypony, I promise!” Twilight nodded and pulled the covers off of Twily. It was so sudden that she shivered. Her tail swished over her crotch, trying to preserve modesty. “H-hey! It’s cold in here, and I’m not wearing anything.”

“We need to be in the proper position to do this properly.” Twilight backed up and lead Twily to step onto the cold floor. Her hooves clicked against the cold wood, and she shivered from the coolness of the room. Still, she wasn’t very concerned about how cold the room was when all she could see was a large, purple, fleshy stick in her way. She looked up at Twilight, the mare nearly poking her in the face with it.

“What’s this?”

“This is an external knowledge converter, one that I’ve designed myself.” She took her hoof and hoisted it into the air. She could feel the blood rushing to the tip, causing the whole thing to shiver in anticipation. She glanced down at Twily, lust building in her eyes. “But that gets cumbersome, so I call it a dick.”

“A… dick?” She raised a hoof and poked at it, causing it to jump at her touch. “Well, what does it do?”

“It takes some time to get used to, so for now, you should heat it up. It is pretty cold in here, after all.” Twilight pushed it into Twily’s face once again, pressing it against her cheek. Despite the cold of the room around them, Twily was pretty warm. “Go on. It’s friendly.”

“Um… okay.” Twily pressed her hooves against the shaft, attempting to hug it. It turned out to be an awkward caress, one that made Twilight chuckle. Twily blushed, embarrassed at her lack of knowledge, and adjusted her position. “Is this right?”

“You’ve got the right idea.” Twilight took Twily’s hooves in her own and placed one on the side. “One here… and one here.” She placed her other hoof on her balls. “To warm it up, you want to rub them, okay?” Twily looked a bit confused, but she followed directions, slowly massaging her. It was slow and gentle, her tiny hooves so different from Starlight’s large ones. It was different, but not necessarily bad.

Twilight placed a hoof against Twily’s head and pushed her closer. Twily tried to look away, but Twilight snaked her tip back towards her mouth. She grinned a bit, prodding Twily’s mouth, trying to break past her defenses.

“You know, Twily, it gets warmer if you put in in your mouth.” Twily looked up, confused. “As long as you don’t bite down, it’ll get warmer.”

“In my mouth?” she asked, eyeing the throbbing meat cautiously. It was big, after all. “I don’t know if it’ll fit in there.”

“We won’t know if we don’t try, now will we?” Twily opened her mouth reluctantly, but that was all Twilight needed. She stepped forward, quickly barged into her mouth and stretching her cheeks. She tried to breathe, but all she could take in was the cock. Twily’s wet squelching throat sucked her in further and further. Twily shuddered from the foreign object entering her, and her horn was sparkling with magic. Twilight pushed Twily’s head back, forcing the last of her cock down into her. “Does it taste good? My dick thinks your insides are nice and warm.

Twily looked up, her horn sparkling with magic uncontrollably. She couldn’t breathe, and she began tearing up. She looked up at her older self, wondering what she was trying to do. She couldn’t even bite down like Twilight told her not to. There was just too much there.

Twilight violently pulled out, suddenly returning her ability to breath. She lurched forward and gasped for air. She couldn’t think of anything, much less try to run. Whatever she became in the future, she didn’t want any part of. But, before she could turn away, Twilight rammed her dick back in, somehow going even further this time.

“Don’t worry, Twily,” she said, smirking. “It’ll all feel good soon.” She couldn’t put up any protest as Twilight slammed her hips into her, filling her over and over, molding a path through her with her dick on the frontier. Her balls slapped against her neck loudly, combining with the whines and groans Twily barely managed to get out.

Twily’s magic began sparking and sizzling as her body tried to stop what was happening, but even it was powerless when compared to Twilight. All the small sparks did was make her want to go harder, faster, and even stronger. She put her hooves on Twily’s mane, making sure she got the full length of her cock.

“Mmm! Mff…” Twily struggled to do anything but let her body be violated. Her tongue involuntarily licked and slurped on her shaft like the world’s largest popsicle was being force-fed to her.

And that popsicle started melting inside her. Without warning, large drops of cum slammed against her throat and landed in her stomach. Every time Twily thought it was over, another glob came down. It was only a few moments, but to Twily, it was a lifetime before Twilight pulled out. Twily had no choice but to swallow what she’d been fed, and double over.

“You did great, Twily.” Twilight patted her head gently. Twily didn’t respond. She had too many things moving through her mind at once. She couldn’t voice anything, she was so shocked. Twilight looked at her dick, not taking a break for a second as it stood strong and straight. She smirked, petting the wet schlong. “Are you ready for the next step?”

Twily froze. She looked at Twilight and turned around, trying to make her way to the door, Twilight caught her in her magic, pulling her back towards her. She shook her head and placed a hoof on Twily’s flank before rearing it back and spanking the foal. Coupled with her lack of breath and the pain in her throat, the tears that had begun to dry began to run again. Twilight smacked and smacked and smacked until Twily stopped squirming. Her ass had turned a healthy red before she stopped.

“It’s not polite to leave when someone is offering you a gift,” said Twilight. Twily sobbed quietly, not offering a reply. “You wouldn’t like it if a friend left you alone, would you?”

“I want… want my mommy,” cried Twily, quietly. Twilight giggled a bit and leaned down to her ear.

“I can be your mommy if you want.” She lifted Twily’s tail with her magic. And poked the foal’s clit. She couldn’t even get wet yet. Sad. “I’ll hug you, and love you, and I’ll give you what you want.” Her tip poked softly against the foal’s asshole, threatening to puncture it next. “But, if you don’t listen, they’ll be consequences.” Twilight bounced her tip against it, coming close to poking through with each jab. “So, tell me. Do you want mommy inside?”

“I-I…” she couldn’t even form a coherent sentence anymore. Twily’s tears and drool mixed to form a pool on the ground. She was still short on breath, and her flank was aching from her beating. Against everything she knew she wanted, when she opened her mouth, she did not protest. “I do…”

“Hm?” Twilight might as well have already been inside. Her head was almost fully inside. She was teasing herself now, egging herself to get on with it. But, she couldn’t without breaking down the last bit of resistance standing in her way. She needed this approval more than the pleasure.

“P-Please, put it in,” she stuttered over her words, her whole body seemingly trying to stop it. “I w-want mommy inside.”

Twilight wasted no time breaking into Twily’s asshole. It was hard. Even for how small she was, the hole was tight beyond belief. She’d barely fit her whole girth in there before her balls were already yearning to cum.

“Good girl,” said Twilight, rubbing Twily’s ass. Poking out from her stomach was a small bulge, proving just how massive she was in comparison. It brought a smile to her face. Twily, on the other hand, gasped at Twilight’s attack. She was short of breath, even though she could breathe. Her back felt like it was a thrust away from being snapped in two, and her stomach felt like it was completely full after a meal. That last feeling didn’t last long, as Twilight pulled out completely with as much trouble as she had before.

Twily’s legs wobbled and gave under her. Twilight watched as the foal burst into tears again. Her entire backside was aching now, and the pain ached all over her body. She picked the foal with her magic, turning her on her back. She covered her face with her hooves, trying to hide however well she could. Twilight leaned down again, and Twily flinched, trying to curl up in a small ball, but couldn’t stop Twilight from planting a kiss on her cheek.

“Do you hate me?” whispered Twilight right near the filly’s ear. Almost immediately, Twily shook her head. Twilight knew she was lying, only doing what she wanted her to, but she still took it at face value. “I think it’s time for me to keep my side of the bargain.”

“Huh?” Twily moved her hoof enough to see Twilight begin casting a spell. She flinched at first, but the aura that surrounded her was warm and inviting. Or, it was at first. Afterward, it became an intense itch that moved from her head to her crotch. Her body began to shake and shudder even harder. “I’m gonna p-pee...” She clenched her legs together as her entire body broke down into pleasure. The bed of nails she was sleeping on turned to clouds.

“Oh?” Twilight reached down and caressed Twily’s clit. Flowing from her was a small trickle of wetness. “So quickly. You’re pretty horny for your first time.”

“What happened?” asked Twily. Twilight smiled.

“You came.” She answered. Her dick poked around her asshole a little more, pushing almost hallway through proved without resistance. Twily flinched, but she didn’t burst into tears like before. In fact, her body did a complete 180! It wanted this. Twily had little time to question it as Twilight stuffed her ass full again. “And now, I’m gonna make you cum again.”

She pulled out a bit, doing short, calm pumps. No reason to break the filly’s back. She was small, after all. Twily had latched onto Twilight, pushing every bit of her cock into herself, and drooling as she did. Every thrust shook her, but she didn’t feel pain. Everything burned with happiness. She didn’t get very far along before a burning started up in her crotch again.

“Mommy, i-it’s coming again!” Twilight shoved herself in, quicker and quicker each time, getting herself in the mood to cum as well. Twily clenched her body as she came again. This time, though, she wasn’t alone.

Thick beads of cum oozed from her tip, quickly overflowing out and bursting onto the floor, Twily’s stomach, and Twilight’s balls. With every pump of cum into her ass, Twily let out a whimper of moan, only making Twilight want to dump more and more into her. She did stop, eventually, after she’d spill far too much cum all over the floor and her insides. When she pulled out, some even leaked out and joined the rest.

The two sat, both panting hard, on Twily’s bedroom floor. Twilight was sure that she’d never cum that hard before, not even for Starlight. She looked down with a smile. Maybe she was just a narcissist. She got up, wobbling slightly. There was only one place she’d left untouched.

“Mommy…” Twily moved her hooves to her clit and touched it, causing her entire body to flinch. She was still leaking juices steadily, and when she pulled her small lips apart, the pink beyond looked wet and cushiony, though she couldn’t see too far. She needed to fix that. “T-This still feels weird.”

“Don’t worry, Twily.” Twilight lifted her dick in her hoof again, already completely ready to go. “Mommy’s dick is right here.”
Twily watched intently as Twilight poked and prodded her pussy, the cum from their previous encounter still sticking against Twily’s lips. She moaned lowly, barely containing her new libido as she waited for Twilight to give her what she wanted. The tip barely pushed past her lips before the air was filled with a loud squelching sound. It was impossibly tight, even more so than her ass. With each inch she managed to jam in there, Twily huffed and moaned more. Finally, she hit her womb, but there were still a few inches left. She tried to pull out, but Twily kept her in place this time.

“Wait… I’m—” She convulsed again, this time with Twilight’s cock blocking the way. The cum had to fight its way out.

“Don’t worry, Twily.” She pulled out what she could and thrust in slowly. “Mommy’s gonna make it feel really good.” She pumped her, deeper and deeper against her womb, trying to break past it. Her body told her no, but Twily wanted that more than anything. She wanted Twilight to fit all of her meat inside. Twilight cast a spell again, this time wrapping herself in it, and reared back enough to ram herself all the way in. As she looked down, Twilight saw her balls slap Twily’s ass.

“M-Mommy is… she’s inside…” Twily moved her hooves to her clit and touched it slightly. She’d stopped counting how many times she’d come since, but this felt like the perfect one. Her body buzzed and her skin prickled, but everything was laid bare. She came hard, the marecum mixing with the mess on the floor. “Spill it in me, mommy!”

Twilight pulled back and slammed in again, the wet squelching turning to music as she pounded her pussy. Over and over, without stopping, her dick paved the way, exposing all of Twily’s hidden desires. She wanted to be stuffed to the brim, she wanted all control to be taken from her, then shoved back in with a thick cock. And, with each thrust, she wanted cum to fill all of her holes at once. She wanted it more than to breath.

Twilight plunged deep inside and shot cum so hard, Twily filled up. Twilight pulled Twily’s back off the floor and leaned in, making sure her cum reached as deep as it could as fast as she wanted. When it bubbled out, it shot forward and hit her face and stomach, sending thick lined of cum all over her body.

“Hnng... Ah!” Twilight grunted and sputtered as she emptied her balls in herself. Everything led up to this moment, where her body shook and sputtered, she knew that nothing would be able to top this moment. She knew she’d said it before, but she didn’t expect for this trip to change that…

This was the perfect pussy.

She pulled out reluctantly, her dick finally going flaccid for the day. She fell on her butt and gasped for air. Twily sat on the floor, surrounded in the fluids of a full day’s work. Her body jumped and twitched every few seconds, and her clit winked, but she looked more or less satisfied. She wrapped the room in magic and returned it to the way it was before they began. All the cum was cleaned up and the musk that hung in the air was replaced with a clean breeze.

Twilight got up and walked over to the filly. She was clean, but her body hadn’t forgotten what happened. She helped Twily get to her hooves. Although she was wobbly, she seemed to be alright.

“Was it fun?” asked Twilight with a smile. Twily’s face was plastered with red, but she nodded. “I suppose that means you’re happy. And mommy is happy when you’re happy.” Twily looked up at Twilight.

“Are you going back to the future?” Twilight nodded her head.

“But, I will be back soon.” Twilight cast a spell at the air opening a small portal in the girl’s room. “Make sure to be a good girl while I’m gone, okay?” Twily nodded, excitedly swishing her tail back and forth. When the portal closed, the room returned back to normal. She sighed a bit but quickly cheered up. She knew she wouldn’t be gone for long.

“At least it’s not cold anymore!” she said, skipping out of her room to return to her normal day.

The night had fallen, and Twily sat in bed. All the lights were out, and her parents were off to bed. The room was cold, again, and Mr. Smarty Pants was here for comfort. Twily watched the moon slowly rise outside of her room window.

She couldn’t focus on anything, though. She was sweating and fidgeted in bed. Her hooves poked her clit, sending more and more levels of pleasure throughout her. She moaned a bit as her marecum started dribbling out. She took her hoof back, licking the sticky sweet juice off before going back down.

“M-Mommy…” she whimpered. This was fine, but nothing even came close to that time. She bit her lip, trying to keep quiet. Even though she knew she shouldn’t, she couldn’t resist. The cum trickled down, warming her thighs. “Ah… m-mommy put it in…”

“Hm…” Her covers we yanked off, and her act was revealed. She tried to hide with her tail, but it was too late. Twilight was already looking down at her. “What do we have here?”

“Mommy!” She tried to jump up, but Twilight kept her down. Twily couldn’t see much behind her as she was laying on her stomach, but she definitely felt the hoof prod her. She shivered at the familiar touch. “Y-You’re back.”

“And I came back to you doing this.” She rubbed her hoof, taking Twily’s words and turning them into long, muffled moans. “You’re so wet, aren’t you? You’re naughty.” Twily pushed her but up and backed up To Twilight.

“Then p-please punish me, mommy.” She started rubbing her pussy against Twilight. “Put your dick inside!” Twilight smiled lustfully down. Somewhere inside of her, she wondered if turning her younger self into a slut, craving for her next dicking was a good or intelligent thing to do.

But those thoughts go to rest when she stuffs her full.

Twilight leaned forward and whispered in her ear.

“Naughty girl.”
