"So, are you ready to go honey?" Prince Shining Armor asked, looking over to his wife and the Princess of Love Cadence as they stood in the foyer of the Crystal Palace, their home and castle, on a beautiful Spring day. They'd been planning this event for a number of months, from calling the Los Pegasus couples' resort they'd chosen, to arranging for Cadence's friend Fleur-de-Lis and her husband Fancy Pants to come along for their own early anniversary celebration, to arranging for only the best, most trusted foalsitter to watch their little filly, Princess Flurry Heart.

"Yes honey, I'm ready. All the luggage has already been sent ahead to the rooms at the couples' retreat we've reserved, and the foalsitter for Flurry Heart should be here any minute. All that's left is for Fleur-de-Lis and Fancy Pants to arrive, a train ride, then for us to enjoy a nice quiet weekend alone..." Cadence said, more than a little sensuality in her tone, before as if on cue there was a knock on the door. "That's probably them now, matter of fact."

Instead of the two ponies they were expecting, there was a younger-looking crystal-pony mare with a courier saddlebag bulging with mail. "Letter for your Highnesses." she said, giving a short bow and hoofing over the letter, before galloping off to deliver the rest of her mail, barely avoiding hitting a pillar on her way out.

Looking at the mail, Cadence grimaced. "It's from Love Bundle, our foalsitter. This can't be good." she said, opening the envelope and pulling out the letter. After a short while of reading, Cadence let the letter fall to the ground, sighing. "Her father is sick in the hospital and she won't be able to make it. Horseshoes..." Cadence cursed, scuffing a hoof on the floor.

"Hey, it's OK honey. We can see if somepony else can watch Flurry. We still have three hours before the train arrives." Shining comforted, rubbing softly between his wife's wings and feeling her relax some, "We'll make this work, I promise. After all, she can't be the only foalsitter available, right?"

Nearly three hours later, with their guests and accompaniment for the trip, Fancy Pants and Fleur-de-Lis, having already long ago arrived and now waiting, Shining and Cadence still hadn't found a foalsitter. "I can't BELIEVE that nopony is available!" Shining half-shouted in frustration, with Cadence meanwhile out of the room and tending to Flurry, "If we can't find somepony to watch Flurry, we may have to cancel...and I know Cadence has been looking forward to this for months, ever since I told her where we were going for our anniversary."

"Well it is mating season, meaning most ponies are 'tending to it' with their partners and need a foalsitter to watch the kids in the meanwhile. Are you sure there's nopony you can call on? Your staff? No friends, or anypony close to the family that you can trust?" Fancy Pants asked, with Fleur meanwhile having her side pressed to his and nuzzling into his neck, being very physical with him.

The reason why was quite clear to both stallions: like most mares during this time of year, Fleur was in her powerful Spring estrus, her instinctive need to be close to her stallion and sexual desires both very high. The pheromones she was putting out also had both Shining's and Fancy's penises unsheathed and at half-mast, though both seemed to understand it was an involuntary reaction to being so close to the fertile, and rather beautiful, young mare and neither took offense.

"Oh, I 'ope zat vee can go. I vish very much to see if zee cloud beds at our 'otel are as soft as I 'ave 'eard zey are. Tu agree, oui? I know you do, mon beau cher Fancy." Fleur practically purred in her Prench accent, earning a throb from both stallions' members at the unmistakably sexy undertones and implications that statement contained.

"Don't worry, I'll figure this out." Shining said back, before his eyes widened, a smile coming to his face. "I've got it! Sunburst, of course! How could I not have thought of him sooner! He's Flurry's crystaller, somepony who has officially dedicated himself to teaching and protecting her! I'm sure he'll be more than willing to watch her." Shining said and, with that, quickly summoned a quill and some parchment, writing 'Dearest Sunburst' at the top.

"I...I came as...fast as I could. Your Highness...I...received word...you needed me to..." Sunburst gasped out as he practically burst through the palace doors, wiping his sweaty gambroge-orange forehead with a cream-white hoof and lower leg, his two-toned vermilion mane, tail, and beard looking slightly windswept and frazzled. Clearly out of breath from the long gallop from his residence that was a short distance from the palace, and as he was gasping for air, he paused his speech and his nostrils flared as his sensitive muzzle picked up an almost sweet, musky scent, each gasp bringing more and more of that very nice scent into his nose. The instinctively-calling scent, he knew, of a fertile mare in full estrus only mere hours away from ovulating, her scent begging him, a stallion, to breed her and claim her womb for his foal; to fill her with his seed now, before it was too late and another stallion claimed her womb for their own foal.

As he looked over at the source of the scent—a rather beautiful white-coated mare he knew as Fleur-de-Lis—Sunburst saw that her pale-pink tail was flagged over her back, as was to be expected of a fertile mare wanting to keep her nethers cool and to 'show off the goods' instinctively, indeed doing just that and giving Sun a full view of Fleur's swollen pussy. Her usually light-pink vulva was a much deeper magenta instead, the white hair around it coated in her yellowish lubrication.

As Sun watched intently, as if in slow motion, a small drip slowly fell off of her clit as it winked, dripping onto a small sectional carpet along the foyer's mostly crystal flooring to join the small puddle already there. Already he felt his penis unsheathing, his flare poking out just as were those of the other two stallions in the room."...um...to watch Flurry?" Sun forced out between breaths and at the sight he'd just seen, getting a nod from Shining as he struggled to tear his eyes from Fleur's puffy pussy and only just succeeded to look at Shining approaching him.

"Yes. If you can, we need you to watch Flurry Heart for the weekend and we'll be back by Monday afternoon. You're our last resort." Shining said, nodding, "I think I should let you know that, given it's the Spring mating season, most of the interior castle guards and all of the castle staff have been dismissed to spend it with their partners, though there will be a small group of un-mated guards who volunteered to remain here to guard the castle and especially you two. I expect you to take care of her as though she were your own daughter, and..." Shining said, but Sunset drifted out as he felt his eyes drifting to Fleur again, seeing her pressed up close to Fancy again, with him sporting a full erection now as she softly nipped his withers or kissed him on his cheek, constantly grinding her side to his.

"...and if anything happens to her..." Shining said in a firm tone, glaring at Sun, while the harsh tone also drew his attention back to Shining and off of the mare in heat having verbal, and just short of actual, sex with Fancy; to make his hanging threat clear. "...understand?"

"Y-Yes, um, Prince Shining Armor. I'll watch her and protect her with my life." Sun said, giving a small bow.

"Good." Shining said, his grave expression and tone now once more lighthearted, "Now, you'll have full access to the castle, save for my and Cadence's personal bedchambers, and the guards will be informed of such..." Shining paused and glanced over to Candace, who had returned carrying the younger filly Flurry Heart on her back. Shining quickly cast a spell to hide his erection upon seeing them enter, not wanting his daughter to see him in such a state, Fancy doing the same out of common respect and decency. Sun's was hidden by his cape.

Seeing the adorable foal with a big smile on her face always caused butterflies in Sun's heart. "...and speaking of the guards, they will also be instructed to serve your and Flurry's wishes as though they were mine," Shining said, "Also, I'll be giving you our usual foalsitter's rate...plus a bonus for going out of your way to do this for us."

"Sir, I'm only too happy to watch her. I swore my life to teach and protect Flurry at her Crystalling years ago and I would love to have some alone time with the little gal." Sun said, smiling at the sight of Flurry, his virtual daughter, now standing next to her mother as he trotted over and gave Flurry a soft kiss on the cheek, getting a nuzzle from her in return; "It's my honor that you trust me so much to watch your daughter."

"Great job Shiny, you found someone to watch her. I knew you could do it, my big, handsome stallion. My hero." Cadence said, giving Shining a nuzzle on his neck, getting a shudder from him given the increased sensitivity that his arousal from Fleur's pheromones caused him, causing his invisible erection to twitch beneath him. He knew what she was likely insinuating, his boosted libido from Fleur's heat likely to promise a fun weekend for them as well, especially if she went into her own heat, which would be happening any day. "I'll just have to be sure to properly reward my hero tonight..."

"Right, so, thanks again so much for doing this Sunburst, you're our hero. Again, we'll be back Monday afternoon and I'll pay you then." Shining said and, with a wave of the hoof and a final kiss from Cadence and him to Flurry, he led the quartet of ponies out of the front door. The last thing Sunburst's eyes were drawn to was the reflection of the sun off of Fleur's wetness as her clit winked one last time, then the door closed, leaving Sunburst more than horny. Fully erect and with a mare's pheromones rolling through him, Sun was thankful that his blue cape kept his undercarriage hidden from view, lest Flurry Heart may have seen something she shouldn’t have.

"So, what do ya wanna do now, Sunny?" Flurry asked with a big smile, hugging Sun's forehoof and nuzzling into it. She'd always liked Sun, viewing him as basically a big brother to play with, and loving and trusting him as such too. They constantly played out in the yard and around the castle when he was there, though more often Sun taught her how to slowly gain control over her powerful Alicorn magic, even if she still had small, and some not so small, outbursts here and there.

I want to find a mare and rut her. Sun thought, but instead smiled down at the little filly, knowing she couldn't understand his plight. "Well, we could go to the study and I could read you your favorite story, how's that sound?" Sun asked, getting a huge smile from Flurry as her very-light-magenta wings unfurled and flapped once in excitement. Her tightly-curled three-toned mane of cerise, violet, and arctic blue almost vibrated as she started bouncing a bit in place, excited that her playmate was here to spend time with her.

"Yes please!" Flurry asked in her little filly voice, making Sun smile at that, feeling his heart thumping at how adorable he found her.

"Alright, let's go." Sun said, levitating Flurry up on his back and getting a quiet 'wee!' from her as he did, before moving at a quick trot to the study, earning a quiet squeal of joy from Flurry as he gave her a pony ride.

"Aaaaw, but I don't want to go to bed yet Sunny! I wanna play with you more!" Flurry whimpered as she lay in her 'big-girl' bed, looking up at Sun and pouting, her big opal-blue eyes looking much like a begging puppy's would.

The room was colored primarily in alternating stripes of light arctic blue and light cyan, decorated with thin trees with opal trunks and branches and topped with cobalt blue leaves, clouds of a light grayish-blue, and stars of light cerulean blue-grey. On one wall was a large window with an almost crown-like shape made with its white muntin and mullion, a large pink heart in the middle with blue diamonds on either side, while another window was on another wall near her bed. This window looked almost like a bloomed flower with rounded petals, in its center another large pink heart, small diamonds surrounding the outer edges at what would be the twelve, two, four, six, eight, and ten hour marks if it were a clock, as well as one directly above the heart in the center. Crystaline pillars made of the same pink, purple, and blue-segmented crystals as the floors helped support the ceiling of the room, her bed's base made of the same crystal as the pillars but the mattress instead being made of a white cloud, with the pillow being enchanted as to stay atop the nearly weightless substance. Finally, in the corner near the bed, was Flurry's toy chest and bureau, various toys scattered about it as it remained open from Flurry and Sun's earlier playing session.

"But we already read 'The Princess and the Mirror Pond' twice, then you ate a nice dinner made by the very nice guard Gleaming Spear, then we played outside until it got dark, then we played with your toys for a couple of hours! Now you need to go to sleep so you'll have the energy to play more tomorrow." Sunburst explained, even still seeing Flurry pout, before getting an idea. "Tell you what: if you go to sleep now, I'll personally make you your favorite chocolate-chip pancakes tomorrow."

That seemed to get Flurry's attention, Sun noticing her tail swishing under the covers as she nodded enthusiastically. Soon she shifted a bit to get comfortable and closed her eyes, Sun smiling and kissing her on the forehead. "Goodnight, my precious little filly," he said, before then leaving the room with the door cracked just a bit like how Flurry always wanted.

Now that Flurry was asleep, Sunburst ventured to the main foyer which was only a brief trot from his personal bedchamber, the room given to him upon becoming Flurry's crystaller, and seeing that a lone guard stood watch over the front door. "Hey, Crystalline Bulwark, would you do me a favor and bring a pot of ginseng tea up to my room? I'm going to be reading and that brew always helps me concentrate." Sun asked, getting a nod and small salute from the stallion as he then left towards the castle kitchen to brew the tea. Sunburst looked around the now empty foyer, making sure he was alone, before walking to the rug where Fleur had been standing before. Sun knew he wouldn't have but a couple of minutes until the guard returned, so he had to make this quick. Wanting a little 'help' with what he intended to come, Sunburst lifted and carefully folded the small area rug, before moving one from another area to replace it.

Taking his prize to his room, Sun was pleasantly surprised to find that the tea he'd requested was already there on his desk. He placed the rug down and unfolded it on the floor of his own room, feeling his sheath swelling already at just the thought how naughty what he was doing was; how naughty getting off to the scent of another stallion's marefriend's estrus was. His lust from earlier was not forgotten and, as he stuck his nose into that spot where Fleur's fertility-telling fluids had puddled and took a deep sniff, he instantly felt his sheath stirring in reaction to the pheromones of an in-heat mare.

Sun's mind fogged with newly-invigorated lust as he buried his muzzle into the rug, sniffing deep again, feeling his member growing harder with each deep sniff to prepare to breed the fertile mare. Soon he stood there with a full erection, still sniffing deep, before lifting the rug again with his magic and bringing it over to his bed. Placing it on the pillow beside him as he lay on his back with his hind legs spread-eagle, his lower-than-average-sized, seven-inch erection was on full display.

<Sun held Fleur close to him, rubbing his hoof softly against her swollen, needing slit, teasing her as he worked her up more while she used her magic to rub his hard-on back in kind.>

"Mmm, you want it don't you Fleur?" Sun whispered as he lit his own horn and started to slowly rub his fully pink member with his magic, feeling it twitching with each rub. He took another deep sniff of her fertile scent, letting it fuel his fantasy.

<Fleur suddenly stood and climbed atop him, grinding her slit against the top of his member as she bent it backwards slightly with each motion, moaning as she did.>

"Mmm, yeah, show your stallion how much you need him..." Sunburst moaned as he kept rubbing, the sensations getting more intense as well as the throbs coming from his stallionhood. "Yeah Fleur...just like that..." His hips were now meeting a steady, instinctive pace of thrusting into the warm, gently tingling magic surrounding his whole member.

<Fleur had now mounted Sunburst griffin-style* as he lay on the bed, her hooves resting on his chest for balance. She started rubbing her lower lips and clit with his cockhead, teasing him further as he prodded her only enough to spread her estrus-swollen lips slightly before pulling back, leaving both whimpering and trembling in need.>

"Come on you naughty mare, do it already...take…my virginity..." Sun mumbled, his eyes sealed at the sensations of teasing his flare in reality as she was in his fantasy. The musky-earthy scent of Fleur still in his muzzle, Sunburst upped his actions more, stroking himself much more firmly as pre-cum started dribbling from his tip, his hips started to shift up with each downward stroke, his back hooves starting to kick and dig into the mattress in the intensity.

<Fleur finally let Sun penetrate her, letting him feel her tight, warm innards surrounding the flare of his stallionhood inside her, the rest swiftly following as he filled her up with himself, spreading her needing passage as he'd never felt before.>

"B-Buck you're tight..." Sun whimpered as he squeezed himself tight with his magic, doing his best to mimic a marehood's sensations from how he was told it would feel from his more experienced friends. He was still a virgin, always focused on studying and his hobbies more than mares. Now, however, his thoughts were consumed by at least one mare, his body and mind working together to relieve himself. As he flipped himself over so he was on his hooves now, his fantasy changed to follow suit.

<Sun flipped Fleur over so he was on top now as she stood in the natural pony breeding position with him mounted on her back, starting to thrust into her now, bucking into her hard as he claimed her as his. Fleur could only tremble beneath his mighty, hilting humps, feeling his forehooves roughly gripping her sides tightly as he plunged his huge twelve inch cock into her welcoming, fertile depths...>

After only a minute or so of very quickly stroking himself, Sunburst felt his flare starting to grow, swelling to triple what it usually was, and grew even more sensitive, with him knowing he was close if he was flaring like this. He kept his hips rocking sharply now into his magic's squeezing sensations, everything coming to a climax. He felt the tightness in his pelvis growing, his need to cum escalating as his pulses of pre grew bigger as he continued to flare...

<Sun's thrusts into Fluer started to become erratic as he plowed her needing passage harder, making his whole body tingle at him forcing himself so deep inside her. At long last, he felt himself hilt her once more as he started to flare, spreading her deepest depths so wide as he grew even thicker inside her inmost sanctuary. "Sunny..." he heard her moan...but it was in Flurry Heart's voice, confusing him greatly...>

"Sunny...Sunny! I need to go potty!" Flurry called out in reality, knocking a hoof hard on Sunburst's chamber door after getting up at her bladder's insistence, but all she could hear from within was him quietly whinnying, moaning, and whickering, whispering something about something being 'tight' and somepony being 'naughty'. "I-I promise I'm not being naughty! I just really need your help going potty..."

"Oh Fleur..." Sunburst moaned out meanwhile inside his bedchamber, his magic still stroking, completely oblivious to his door opening now. After all, his pace was furious, his spell stroking his rapidly-throbbing member, his flare fully swelling as his fantasy also met its climax.

<"Oh Sun. J'aime ton grand bitte très, très beaucoup! C'est plus grand que même Fancy's!"** Fleur cried out in Prench, her body quivering, before she cried out, 'Mon cher Celestia, OUI! Me faire foutre! Imprègne-moi de ta pouliche!'*** As her body stiffened beneath him, Sun humped like a feral stallion into her, feeling her warmth squeezing and squeezing rhythmically around him, her mouth wide, before calling out, again in Flurry's voice, "SUNNY, I NEED TO GO POTTY—">

"—REALLY BADLY!" Flurry finished as she finally couldn't hold it anymore, pushing open the door fully and seeing Sun...doing something with what his magic on what her daddy told her was called a stallion's or colt's 'willy', seeing his face flushed red, his eyes closed, and his magic's light yellow aura moving up and down in the form of two rings along the long, pole-like pink-skinned thing. She also noticed, past his flank being high in the air as his hips jerked forwards rapidly, was that his muzzle was...oddly buried in an area rug she'd seen in the entrance hall.

Flurry had seen the tip her father's 'pee-pee' a few times when she'd walked on him peeing, but never really paid it any more mind than she would his horn or his hoof...but now, with Sun's looking all swollen and huge like this, she found herself more than curious, as though something deep within her was calling her towards it. "What's...that?" Flurry asked, her urge to pee forgotten for the moment as the all-consuming force of a foal's curiosity overtook her and she approached a few steps, "Doesn't it...hurt...being all swelled up big like that?"

As Sun opened his eyes, knocked back into reality by the questions, he looked with wide eyes at the young royal filly who was so blatantly staring at his fully-flared penis while doing the squirming dance of a small pink filly who really had to pee, a mix of fear, shock, embarrassment, and overwhelming arousal rushing through him. Unsure what to do now, he did what he deemed best: ignoring that anything was out of the ordinary. "S-so you need to go to the toilet?" Sun asked, his voice quivering from the pre-orgasmic hormones still rolling through his blood, his still-flared cock flexing angrily, smacking his underbarrel and spurting precum in demand of its denied release, smearing where the thick club-like flare hit with his profuse pre-cum.

"Oh...yeah..." Flurry said, gently shaking her head to try to get that weird musky smell out of her muzzle – the scent that smelled distinctly like Sunburst's own unique scent, but had another, muskier undertone that she kind-of really liked in some inexplicable, unexplainable way to her little filly mind – her need to pee now rushed back to the forefront of her thoughts, "...but, um...what is that?" she asked again insistently, pointing at his penis.

"It's...um..." Sun stammered, sweating now, not knowing what to say. She was so young still to be learning about sex, yet it was his fault that she even saw what she did! "...it's, um...grown-up stuff! Yeah, for adult ponies only!" Sun thought of on a complete whim.

Flurry huffed, her lower lip turning up into a pout. "That's what mommy and daddy said too when I saw him laying on top of her while they were kissing with their tongues last week!" Flurry said, before shaking her head," Fine. I still really need to go potty and really need you to make sure I don't fall in!"

Sun couldn't help but feel a bit disturbed as Flurry said that, as well as more than a bit of relief going through him as she finally dropped talking about his erection, basically telling him she'd seen Shining being intimate with Cadence. With him knowing that Flurry was much too big to fall down the fairly small toilet opening, he knew her fear was pointless, but also knew that foals didn't often look at things logically. He also knew it was likely more about her insecurity of being alone in the bathroom, rather than an actual need for him to actually help her or keep her from falling in. After all, with such proportionately big wings, she could easily keep her balance just by expanding them out fully! "Sure, let's go." Sun said, his member still fully, uncomfortably erect as he got off of the bed, swaying stiffly between his legs as he stood.

"So, why's your willy all big like that?" Flurry asked, getting a quiet exasperated groan from Sun, "I know I hit my hoof once and it got all swollen, and it reaaalllyyy hurt! Does that hurt? Why were you using your magic on it while smelling a carpet?! That’s so silly, Sunny!"

Sun apparently had forgotten how persistent a curious foal could be! "I told you, grown-up things! Your mommy or daddy will tell you when you get older." Sun insisted, "Now come on, we're here. Go pee so you can go back to sleep." <...and I can finally get some relief.> Sun mentally added.

A restroom, one of the multiple sprinkled around the palace, was only a short trot from Flurry and Sunburst's room and they arrived within a minute of leaving his room. Flurry flew with her still disproportionately large wings while Sun walked in an awkward, stiff gait, happy that at least there was no guards around to see his rock-hard stallionhood unsheathed and oozing pre-cum as he was escorting Flurry to the bathroom. His hard-on still insisted to stay hard and fully flared as Fleur's fertility-telling pheromones continued wracking his body with the lust to seed that mare, unwilling to go down until he'd cum...but he didn't want Flurry asking even more questions if he were to squirt his seed!

Flurry, meanwhile, took a squat over the toilet hole in the floor, which was basically a moderately-sized hole that both mares and stallions alike would stand or squat over and do their business in, then a specially-placed magical portal would teleport the waste to a distant, uninhabited wild area where it would no longer be a concern. Sun was unintentionally behind her as she flagged her tail to the side to get it out of the way, squatted, then let her bladder go. Sun watched as his beyond-aroused mind was locked on her exposed fillyhood more than her stream, unable to tear himself away from the sight. He consciously knew how wrong it was to be watching her, a young royal foal, at her most vulnerable time, but couldn't stop himself, his instincts having full reign.

Flurry soon finished peeing, Sun's erection now at full hardness again despite it going down a little on the walk to the bathroom, and was only throbbed that much harder when he saw Flurry winking her fillyhood to get the last few drops off of her, making his member slap hard against his underbarrel again at the unintended erotic display of her, her unintentionally inviting him to breed her. After she completely finished, Sun's face was glowing a bright red as he finally tore his gaze away from her private areas...yet while he knew he should feel shame for peeping at a filly at her most vulnerable time, instead all he felt was beyond aroused again. "Alright, could you wipe me now please?" Flurry asked, nodding towards the toilet paper.

Instead of taking it in his magic like he may have in a more coherent state of mind, or having her clean herself with her own hoof or even using her own magic, Sun instead nodded as he unrolled some of the toilet paper loosely around his hoof a few times, making sure it wouldn't soak through, before seeing Flurry keep her tail flagged up for him to clean her. He couldn't help but have a bit of an internal debate of if he should be touching her there in his state of mind, but eventually he reasoned that she'd asked him to, and it was simply him cleaning her and nothing more.

Looking to see where he was putting his hoof, Sun wiped over Flurry’s fillyhood, feeling the warm, supple, virgin lips of her young vulva through even the thick tissue, feeling them spreading slightly as he wiped upwards. Unintentionally, or perhaps subconsciously, he moved his hoof so the tissue fell off, leaving his bare hoof touching her cleaned nether region, rubbing her filly petals directly. He continued 'wiping' more than strictly necessary, his animal mind savoring the warm, soft feeling of a female's nethers, regardless of her age.

As Flurry started to feel a weird sensation starting in her lower belly, feeling something warm and somewhat hard sliding between her lower lips, she realized Sun had been wiping her for an awful long time...and she realized she didn't feel any toilet paper on his hoof. The warm feeling grew, and grew...until she felt the sensation of her fillyhood doing that thing she always does to get the last few drips of pee out of her, but against his hoof. Thinking nothing of him touching her like that, thinking it was only an accident that the toilet paper fell off, Flurry simply giggled a bit.

"You're so silly Sunny! You don't have to use your hoof to clean me, just use magic like Daddy always does!" she giggled, stepping forward and breaking contact with his hoof, leaving just a bit of her clear sexual fluid on his hoof that the rubbing had generated. Just like that it was over, but still her body's warmth lingered on his hoof, him looking down at the soiled tissue on the floor. Flurry meanwhile dropped her tail as she closed her legs, turning around to look at him again, seeing him simply staring at the tissue. "Um... that goes in the potty too silly Sun!" she said, using her own magic to lift the toilet paper from the floor and drop it into the portal, before giving a yawn. "Your hoof touched me down there so c'mon, clean your hoof so we can go to bed."

Sun dumbly nodded, rinsing his hooves in the sink, before guiding Flurry back to her bed, the whole time having been blue-balled. The unpleasant tingling in his pelvis made him wonder if this is similar to what mares feel during estrus, to be so desperately wanting a stallion to mount them. "O-Ok...I'm gonna go to sleep now." Sun said, barely preventing himself from wrapping his magic around his penis and pumping until he finally had his release right then and there.

"Goodnight Sunny. You're the best!" Flurry said with a smile, getting comfortable under her covers, before finally she turned over and curled up in the fetal position, softly, happily sighing.

Sun smiled himself as he saw the cute display, before turning to leave...

"Sun, could you stay with me until I fall asleep?" Flurry suddenly asked, turning back over to look at him with pleading eyes.

<So close yet so far away…> "Of course I can dear."

Another twenty minutes of pure, nearly agonizing erectile hell, Sun eventually made it back to his room after he was sure that Flurry finally fell asleep, the promise of finally cumming making him move in an awkward canter all the way to his room. Finally, after triple-checking that he locked the door, Sun dove onto his bed, with the whole room smelling like a fertile mare, and his mind simply couldn't take it anymore. Sun lit his horn and summoned the two rings of magic around his member, not caring at all about rhythm or endurance; he needed to cum, now!

Sure enough, within a matter of seconds, Sun's hips were bucking at a frantic, feral pace, all care thrown to the wind now as his nose was rammed into the fertile-mare-scented carpet again, his flare fully swollen once more and his dick throbbing in desperation. Suddenly, his fantasy took a change for the strange when the mare beneath him suddenly changed form...

<Yes, Sunny, YEEEESSSSS~> Flurry Heart cried out in her own orgasm as Sun still pounded into her, Sun feeling her squeezing him inside of her young filly pussy almost crushingly tight, but it hurt so good.

"FLURRY HEART!" Sun heard himself scream to the heavens in reality as he finally found his long-needed orgasm, his stallionhood jerking rapidly as its long-stored load gushed out in massive spurts, painting his covers, the rug, and his underbelly all in his excessive off-white stallion-batter. His hips humped rapidly as he just came and came, pure euphoria washing though him as the previously nearly intolerable tenseness relaxed, the near-stinging in his pelvis replaced by blissful, rhythmic contractions of pleasure and relief.

Finally, Sun collapsed into his own large puddle of jizz on the bed, feeling so utterly relieved as he finally got his long-teased climax...and what a climax it was! Judging by the puddle beneath him, he guessed he had to have put out at least half a liter...and that's not counting how wonderful putting that much out had felt! "W-whoa..." Sun mumbled to himself, rocking his hips slowly into his magic to coax out the final, vestigial remains of the most massive pleasure he'd felt in a long time as his shaft softened.

Now feeling utterly contented, if quite messy, Sun lit his horn and rolled the heat-scented rug up, tucking it in a nice neat magical envelope for later use, preventing its scent from escaping...until he then dropped his levitation spell…

...then he realized something.

"Oh Celestia...I said Flurry's name when I...and fantasized that I was with...with her!"

"I'm gonna get you!" Sunburst half-shouted playfully as he and the named filly were out in the gardens of the Crystal Palace the next day's afternoon, with him chasing Flurry around a moderately-sized grass field used mostly for grazing or harvesting for the castle chef's recipes. Now, however, it was a filly and stallion's playground, Flurry squealing out happily as Sun chased her around, him intentionally not going full speed and giving the little filly a chance to get away. It had rained recently, leaving the ground soft, but Sun wasn't too worried about Flurry sinking into the softer earth at all. After all, even in the unlikely case she did, she could flap her wings or either could use their magic to get her out.

"Aaaah, no, the shadow monster is after me!" Flurry squealed out again in delight as she ran at a full gallop, her little legs like a blur at the speed she was moving. Sun, however, could only watch as suddenly one of those hooves tripped over a large rock, Flurry losing her balance while going at such a speed and falling before he could light his horn to catch her. He watched as she rolled forwards, her wings springing out on instinct as she tried to regain balance, but instead they only got muddy along with the rest of her body as she rolled head over hooves into a large mud puddle.

"FLURRY!" Sun called out in a near panic, now worried to move her in case she'd broken something, most worried about her wings getting hurt, or worse, broken, or possibly even her getting a concussion or other injury. As Flurry quickly looked up at him calmly, her eyes wide and a big smile on her face as she stood up without any seeming pain or problems, he felt a rush of relief go through him that she was clearly unharmed.

"Wee, that was fun! I wanna do that again!" Flurry called out, and as she stood, Sun could see that the once pink filly was now almost completely dark brown, coated in the nearly-black, fertile soil from wingtip to hoof, her tail and mane not escaping their filthy fate either.

Sunburst, despite being relieved that Flurry was unharmed, was now faced a new problem: the little alicorn filly was now coated in thick silty soil, her wings, mane and tail included, and Sun knew that it was going to be a nightmare to clean off. "Well I really hope you don't do that again! You scared me so badly I'm surprised my mane and coat didn't turn white!" Sun joked, getting a reciprocating giggle from Flurry as he scooped the filthy filly up in his magic, containing the mess to a yellow-colored magic bubble as he took her inside.

"Aaaw, but that was fun!" Flurry said, pouting a bit, though all Sun could really see of her was her beautiful blue eyes – her father Shining Armor's eyes, Sun noted – and patches of her pale pink coat or a few unaffected strands of her mane. As he carried her into the nearest bathing room, Sun nodded to a couple of guards on the way, both chuckling and shaking their heads slightly at the muddy little filly in Sun's magical grasp, causing her pout to deepen.

Soon making it to the bathroom, Sun popped his magical bubble and Flurry was placed gently on her hooves on the smooth crystal floor, before Sun turned the tap on and grabbed a nearby removable showerhead in his magic instead of the filly. After letting the water warm some, Sun then turned the stream onto Flurry, getting the bulk of the muck off of her, with her meanwhile squirming a bit at the pleasant feelings of the warm water and massaging showerhead on her body. "Sunny...I always take a bath, not a shower!" Flurry protested, getting a small smile from Sun.

"Well, it wouldn't make much sense for me to try to clean you in a bath full of muddy water, would it?" Sunburst asked, continuing to spray Flurry's still-erect wings now, earning a gentle shudder from her as he cleaned those very sensitive limbs, turning the pressure of the water down appropriately; "I need to get most of it off of you with this, then you can go into the bath."

Flurry nodded but, despite her fussing, she actually very much enjoyed the warm water washing over her and the massaging showerhead relaxing her muscles, with Sun's hoof occasionally coming in to loosen a stubborn spot of filth in her mane or tail that the stream alone couldn't get. Her wings relaxed, the longer wings' tips now resting on the floor, until Sun positioned the stream to wash over her croup. On reflex to the sensations there, Flurry's now-clean tail started to flag a bit, with Sun taking that opportunity to spray under her tail and get any mud that had gotten there off. Her wings shot back up and her tail flagged the rest of the way, her rump facing Sun and giving him an unobstructed view of her vulva and ponut, both of which were a few shades of pink darker than her coat.

Slightly embarrassed at the brief glance of her privates and feeling a light blush on his face, Sun looked away, before nudging Flurry softly. "C'mon, let's get the bath running." Sun said, Flurry smiling at the thought of soaking in a warm bath. Shortly after, Sun and Flurry stood at the large communal bathtub, easily able to comfortably fit four or more ponies at once, raised crystal around the tub's sides acting as seats. Soon the tub was full enough with warm water, with Sun placing Flurry on on the ground of the tub, submerging her whole body when she stood, but also leaving her head well above the waterline he'd filled it too. Her tail floated on the water, as did her mane, its usually tight curls loosened by the warmth and making a cascade of colors across the top of the water.

"Alright, now..." Sun said, grabbing a bottle of mane and coat shampoo from a nearby shelf, "...let's get you clean."

"Wait..." Flurry said, clearly looking displeased and possibly mildly distressed, "...could you come in the tub with me? Daddy always is in the tub with me when he gives me a bath..."

"Flurry...I don't know if that's such a good idea..." Sun said, memories of the previous night coming back to him – of him calling out Flurry's name in his moment of climax while he'd cum, his mind's eye seeing her beneath him as his thick member disappeared inside of her tight little fillyhood – and he worried that being so close to her would again rouse such feelings. "I really don't think I should."

"Aw, c'mon, why not?" Flurry asked with the small whine she always used when she wasn't being given something she wanted, looking up at Sun with wide, pleading eyes, her muzzle in a pout. Sun felt his heart pound in his chest at the begging expression from the little Princess, gulping, before finally nodding his head to alleviate some of the sheer cuteness of the pleading being directed at him.

Sun knew from his dabbling in pony psychology that this, like when she'd needed him to help her go to the bathroom the previous night – and unintentionally blue-balling him for at least thirty minutes while he'd done that and then waited at her bedside until she went to sleep – stemmed from the instinctive herd mentality of a foal never leaving its mother's side for fear of being snatched up by a predator. Sun now realized that Flurry's instinctive insecurity and fear to be alone for any amount of time was rather strong, and also knew that denying staying close to her could possibly make the trait worse and possibly pass into adolescence or even adulthood instead of it eventually phasing away when she grew to be a young mare like it does with most ponies.

"Fine, fine, I guess I can..." was all that Sun could get out before he was interrupted with a loud, excited squee and loud splashes coming from the tub, Flurry's wings flapping in her excitement and getting water everywhere. "...OK, OK, STOP FLAPPING PLEASE! You're getting water all over!" Sun said as he then stepped into the water, with it only coming up to the top of his legs, the pleasant warmth on his sexually sensitive chest, as well as his sheath and balls, making him softly shudder at the sensation. "Right, now let's get you clean.

The bath was a pretty standard affair, with Sun first using his magic and some mane and tail shampoo and conditioner to clean the silt out of Flurry's mane, getting the fine particles out of her mane with the help of a fine-toothed hairbrush and washcloth. As he pet a hoof through her mane to make sure he'd cleaned it completely, he felt just how silky-soft it was, the conditioner clearly working wonders. He then moved down to wash her crest and withers, using the same brush to clean her coat, all the while feeling Flurry nuzzling against his chest, unintentionally activating the erogenous zone. Trying his best to ignore the sexually pleasant sensations, and enjoying the innocent affection nonetheless, he washed her front legs and hooves, before he then moved down to her sides and cleaned them. As he noticed her wings were still quite dirty, Sun grabbed a bottle of a second type of shampoo specially designed for cleansing a Pegasus' delicate wings and feathers, before applying it liberally to both hooves.

Knowing how sensitive a Pegasus's wings are, and knowing it likely transitioned over to alicorns as well, Sun kept his motions gentle, opting to use his hooves instead of his magic to prevent being too rough. "Is this OK Flurry? I'm not being too rough?" Sun asked, getting a shake of the head from Flurry, showing he wasn't.

"No...it actually always feels really good when somepony cleans my wings...please keep going, I like it." Flurry said, her eyes lidding at pleasant, gentle tingling sensations rolling through her wings and upper back as Sun cleaned her wings, her breath increasing as her wings remained stiffened, like they always did during bath time. Sun meanwhile knew through his reading that wings on a Pegasus were highly sensitive to help detect air drafts and thermals, but were also an erogenous zone, with him knowing that Pegasus foals only let their parents care for their wings, or that couples generally only allowed their mates to clean or preen their wings if they didn't do it themselves. He knew this was different, that Flurry was merely a foal in need of cleaning and he was the only one who could, and so merely continued. He meanwhile noticed now that a number of feathers were out of place or broken from her earlier tumble, knowing she'd need to be preened later.

With her wings now clean, her feathers back to their purple and light-pink gradient instead of the black-brown of mud, Sun knew there were a few last...intimate places that needed cleaning, though he was very hesitant to do it given his previous night's fantasy. Looking her over and brushing his hooves along her whole wet, warm body, making sure it was clean and only being greeted by a healthy, beautiful silken coat and an increase in Flurry's breathing bordering on panting, Sun knew her whole body was clean besides the last places and her back legs and hooves.

"OK Flurry, now I need to clean your back legs." Sun said, watching as the foal nodded and turned her rump to him, lifting a back leg for him to reach. After cleaning her legs, Sun then moved the washcloth and comb up to her stifles, cleaning softly over her pale-pink blank flank where a cutie mark would one day be, noticing once more that Flurry’s rump was well rounded, as being a royal foal gave her a diet full of healthy foods, giving his hooves something substantial to clean. As he cleaned that sexually sensitive area, he then realized her tail was flagging up, his sheath soon starting to swell in reaction to all of the stimulus so far. He continued on though, too entranced to stop now as he started cleaning her croup, the touch on that area making her tail flag the rest of the way on reflex, though leaving her limp, wet tail blocking his sight of the treasure beneath.

"O-Ok...now I need to clean...under your tail." Sun said to her, his voice stammering at the highly sensual situation he found himself in, with Flurry oblivious to how erotic this all was to him. Seeing Flurry nod and move her tail to the side now, leaving her young, nubile folds revealed to him completely, Sun felt himself start to slide from his sheath as he caught a scent of the filly's arousal. That sweet, distinctly feminine scent told him that he'd been unintentionally teasing her sexually while cleaning her, her body reacting to his innocent touches as though he were a lover.

"That's OK, you can clean me there." Flurry said, smiling. She always loved when her daddy cleaned her under her tail. It always felt really good.

Getting a better look now than before, Sun saw that nestled between those chubby flanks was her small, swollen, glistening, light-pink labia just a few shades darker than her coat, lightly-wrinkled between her anus and the start of it. Its bottom portion gently curving upwards, with that area hiding the little pink pearl within that occasionally peaked out in Flurry's aroused state. Above it was Flurry's ponut and dock, the prior the same color as her vulva and the latter the same color as her coat. Each time she winked, Sun felt his erection throb, now fully hardened at the sights and scents Flurry was giving him. Being sexually repressed, his lust finally had found an output unintended by him, it would seem...in the form of an adorable little filly that he truly cared about deeply.

Sun bit his lower lip as he looked at Flurry's ponut and winking pussy, then to the washcloth. Wanting to act casual despite the fact that he had a boner bobbing between his hind legs, only inches from touching her, he started to clean her inner stifles first, then moving on to her dock and anus, being very careful and feeling that all were very plush and warm. Finally, he moved on to her small fillyhood, seeing it was slightly swollen in her state, each wink her tiny heart-shaped, light-pink clit made making his member want to flex hard and smack his undercarriage, but he barely restrained himself.

He then rubbed over that glistening mound, not sure how much of its wetness was bath water and how much was Flurry's feminine arousal, Sun hearing Flurry give out a soft gasp...as he felt her pussy wink against his hoof, then again each time his hoof brushed over its cleft. "S-Sunny, you touching there makes my head f-feel funny..." Flurry said, feeling the same kind of tingling pleasure she had when Sun cleaned her wings, but more intensely and between her legs instead of along her back and wings; like her father cleaned her down there, but Sun just kept rubbing.

"Sorry Flurry...I'm just..." Sun replied, though he didn't know how to explain why he was doing what he was. Her vulva was already clean and he knew it, but he couldn't help but keep rubbing her winking fillyhood, that sensation of her pussy twitching against his hoof and the scent of feminine arousal calling to his deepest animal mind; telling him that this mare was ready to be bred. "I should stop."

"No, It's OK Sunny...that feels really good. You can keep going." Flurry said, shifting her hips against his rubs. Her daddy had never rubbed her down there this much before, and it was starting to feel really nice.

Unable to hold it back anymore as Flurry basically asked him to rub her pussy, Sun's penis flexed hard, smacking against his underbarrel with an quite audible smack.

"S-Sun, what was that?" Flurry asked, startled at the sudden sound as she looked back the stallion over her back. Sun's face was meanwhile as red as his mane as she looked back between his legs at the rather obvious penis standing tall and proud between his legs, "Oh, your thingy came out again? Why? Doesn't it hurt when it gets all swelled up like that? Let me see if you're OK." Flurry said, and before Sun could do anything, Flurry had stood. To his arousal and horror both, she grabbed his erection in both hooves.

Sun gave a quiet, involuntary breeding whinny as his hips shoved forward hard, nearly knocking Flurry down with the force of his thrust. He felt like he hadn't released in a week despite having a massive climax the previous night, his flare oozing precum like he'd been abstinent his whole life. "F-Fl-aah-F-Flurry!" Sun stammered out, gritting his teeth, unable to do much else at the erotic pleasure rolling through him now even with that simple touch.

"What's this clear goo stuff coming out of the top? Why is it twitching?" Flurry asked, gently rubbing up and down now, never having been able to touch her daddy's penis like this before. Sun meanwhile was becoming overwhelmed at the situation. Before he completely lost his mind to lust, Sun's last shred of decency made him light his horn and gently grab Flurry's hooves, pulling them from his oozing penis. Instantly, she looked upset and tears started to form in her eyes. "I'm sorry Sunny! W-was I hurting you?" she asked, looking up at him with heartbreaking, massive eyes.

"No, no, it's nothing like that." Sun said, shaking his head softly, before walking over to her and nuzzling behind her ear, "It's just...this kind of stuff is something only adult ponies should be doing, not a little filly and a stallion." Sun tried to explain, knowing that unwanted sexual contact, though especially with a foal, was not only amoral but also highly illegal, with those responsible facing heavy dungeon time. Sun only hoped Flurry wouldn't tell anypony of what had happened in the tub, not knowing if it was OK with her despite her asking him to continue.

"But, the look on your face...it looked like it really hurt." Flurry asked, still nearly crying.

"No, I promise, it didn't hurt. It..." Sun said, biting his lip, before sighing, "...it felt kind-of like how I'd imagine you having your wings or...fillyhood...touched feels."

"My fillyhood? Oh! You mean my princess parts?" Flurry asked, the gears in her head turning now as she softly touched her vulva, "But...if it feels good for you like you rubbing me down here felt for me, why'd you make me stop?"

At that, Sun drew a blank. Why had he made her stop when it felt so good? "Because only stallions and mares are supposed to do this." Sun said resolutely and, before she could protest, he took Flurry out of the tub, climbed out himself, and had her wrapped in a big fluffy pink towel the same color as her coat within seconds.

"Well, I'm sure your mommy or daddy will tell you all about it later, but you're too young for now. Now, let's get you dried off so we can go have dinner. I smelled soup on the way in, so one of the guards must have started dinner." Sun said as he then dried Flurry and himself as completely as he could with the towels in his magic, focusing mostly on her mane and tail, before removing it. As he took the towel away, Sun felt his heart throb in his chest. Flurry was now very fluffy after her bath, her usually poofy mane and tail half as much larger, her coat having small tufts of fur poofing up, and her chest's tuft looking especially plush. Sun had never seen her like this before, barely restraining himself from giving an audible 'aaaaw’' at the sight.

As though on cue to the mention of food, Flurry's stomach growled loudly, making her chuckle a bit. "Yeah, I could eat for sure." she said, and it was then as though the past half-hour was forgotten. Sun's erection faded before he slipped back into his sheath, Flurry's aroused scent also fading away as her own arousal dropped, before finally they were back to normal and ready to leave the bathroom and go eat.

"I swear, Gleaming Spear should have gotten a cutie mark in cooking instead of security. That minestrone soup was perfect!" Sunburst said, patting his content belly, now filled with soup, salad, and fresh bread. All the ingredients were fresh from the castle's own gardens, and the bread from the castle bakery. The few castle guards, including Gleaming, ate quickly before returning to guard duties, now leaving Sun and Flurry alone in the grand dining room.

"Mmhm, he always cooks when the royal chef is sick or otherwise away." Flurry explained, taking a bite of the cookies that the royal bakers had made that morning before heading home to spend time with their mares. "You should try his hayburgers!" Flurry's expression suddenly took on a considerative expression as she chewed, clearly thinking about something hard.

"Bit for your thoughts?" Sunburst asked as he saw her expression, hoping it wasn't something serious...and also hoping it wasn't about earlier either.

"Well, it's just...last night when I came in to get your help going potty, you kept saying 'naughty'. Were...were you talking about me?" Flurry asked, her expression of one of hurt.

Sun felt his heart melting at the sight of Flurry being sad, and knowing he was the cause of it made his heart twist. "No, no Flurry!" Sun said reassuringly, reaching a hoof over to lay it over Flurry's much smaller hoof, looking directly into her crystal-blue eyes brimming with unspent tears, "No, I was just...having a make-believe time with myself and...making myself feel nice." Sun said, hoping that explanation would suffice.

"But...who was being naughty? And why were you rubbing your… your thingy while calling somepony naughty?" Flurry pressed, Sun once more getting that 'this is wrong' feeling in the pit of his stomach as memories of his rutting Fleur, then Flurry, came back to mind, his sheath starting to swell again.

"Please tell me? Pleeeease?" Flurry asked, her wide eyes still welling with tears, her lower lip pouting, and Sun could swear he could hear quiet little whimpers coming from her.

"Well..." Sun started, going to try to divert her curiosity again, but he knew that him derailing the topic wouldn't last forever. This foal was far too curious and insistent to simply take 'no' for an answer, taking her stubbornness from her father too no doubt, just like his eye color...and persuasion skills.

"...OK, I'll tell you why I was touching my willy with my magic."

<Wait, what?! I didn't mean to say that aloud!> Sun thought as he'd realized what he'd unintentionally said, his mind now a chaotic flurry of shame, guilt, and dread of what may come of him telling her...but also major arousal. He was going to tell a foal the ins and outs of breeding. He thought about how he was going to let her know just why he was rubbing his penis, why it was swelling so big...and what he was about to do when she walked in on him. He was going to tell her how good masturbation felt and why him touching her pussy had felt so good, how foals were made...and maybe even how to pleasure herself...and how to pleasure him, her small hooves rubbing along his—

<Stop! What!? She's just a little foal! She's too young to learn about, let alone have, sex! Too Innocent, and probably even too small to even fit me!> Sun's rational mind argued, fighting his urge to become erect right now and finish what the time in the bath with Flurry had started.

<She's going to be going into her first heat soon. Don't you want her to be prepared for what that's going to entail? Plus, she asked you to keep rubbing her!>

<Well no, but...but teaching her that is Shining and Cadence's job! They're her parents, not me!>

<You're her Crystaller, which is like a second dad. You're as responsible for her upbringing, teaching, and safety as her parents! Shining and Cadence basically made you one of the family that day! Don't you want her to be able to handle her sexual urges in a healthy way, instead of just jumping at any colt or stallion during her first heat just to relieve her breeding urges and possibly getting pregnant by him? Isn't it better to learn these things when she's barren still? When it's safe, and with somepony she can trust?>

<But...>

<Just telling her isn't anything bad. Just tell her about estrus, sex, how to pleasure herself...how to pleasure her stallion...watch her rub her little fillyhoo—>

Sun shook his head hard to break that train of thought in his internal debate, shutting it down before he once more exposed his penis to Flurry.

"Yay, I knew you'd agree!" Flurry cried out happily, virtually beaming with her excitement at Sun having given in, "Now, why were you touching your pee-pee, and why'd it get all hard when you were in the bathtub with me? Why did I feel all funny and nice when you touched my wings and princess parts? Why—"

Sun held up his hoof to silence the overexcited filly, noticing that her wings had sprung up in that excitement, now flapping softly. "OK, OK, I'll tell you." Sun said, getting an instant nod from Flurry, her still ultra-poofy mane bouncing with her rapid nods. Looking around, seeing they were still alone, Sun quickly cleaned the dishes with his magic then teleported them to their cabinet, doing the same with the goldware. He then lifted Flurry and gently placed her on his back, feeling a certain dampness soaking his coat around where her crotch was...but simply chalked it up to her still being wet from the bath. Certainly she wasn't...

"Come on, let's go to my room. I'll tell you there." Sun said, feeling Flurry nodding more, before he then gave her a pony-back ride to his room to tell her exactly what she'd asked to learn while he could swear she was grinding her fillyhood on his back the whole way. With no details spared.

"OK..." Sunburst said as he and Flurry Heart, whom he was watching for the weekend, sat on his bed, "So what did you want to know first? What do you know already?" Sun was still having an internal debate over agreeing to tell Flurry about the basics of the birds and the bees at her request, though he was so aroused right then that his rational mind and morals were battling with his instincts. One part was debating she was too young to know it, but another rationalized it to himself as simply teaching her to be ready for what to expect in her first estrus; that he didn’t want her to simply get pregnant by some random colt or stallion without knowing the risks, and that was at least partially true. He really did love her, and wouldn't want something like that to happen to her.

“Well, I don’t really know much. All I know is that I have ‘tee-tees’ and ‘princess parts’, and that my wings feel really good when they’re rubbed...and so do my princess parts and tee-tees too. I also know that colts and stallions have a ‘pee pee’ and use it to pee with, but yours got all hard and stuff too! Stallions also have ball things behind where their pee-pee comes out of. Then my princess parts moved all funny and...you said you liked it when I touched your pee-pee...” Flurry said, looking at Sun, relaying all she’d gathered from their earlier time together in the bathroom.

“Well, yes, that’s correct. The reason why it feels good for them to be touched is because your vulva and my penis...they’re used for more than just going potty.” Sun said, watching her eyes widening in surprise at the new concept, “In fact, they’re used for something that can be really fun and…” Sun paused, before telling her their real purpose, “...but that fun thing will make foals too if the conditions are right."

"Foals?" Flurry asked, looking more intrigued now.

"Yes, they can make foals, but more importantly they will only make you and a stallion you’re with feel really good if the conditions aren't right, which they're not right now for you.”

That sure piqued Flurry’s interest. “Even better than I was feeling in the tub? That felt really good when my princess parts were doing that moving thing, and when you touched them!” she asked, remembering the nice tingles that went through her when he’d cleaned her, and previously when the toilet paper had slipped from his hoof and he’d rubbed her directly. How she felt like she wanted to do that moving thing with her filly parts; that she wanted Sun to see her doing that for some reason.

“Well it can feel really good, if the two ponies do it right.” Sun said, wondering how to go about this, though his scientific mind quickly defaulted to anatomical. “Well…” Sun started, “...with the mare reproductive tract, the outermost part of a mare's anatomy is called the 'vulva', or ‘labia majora’. Past that is the ‘labia minora’ and ‘clitoris’, and deeper still is the entrance to the ‘vaginal canal’...” Sun explained clinically, as though teaching a class, oblivious to the confused look on Flurry’s face, “...then deeper still is the ‘cervix’, which leads to the ‘uterus’, ‘Fallopian tubes’, and ‘ovaries’ which produce 'ova'.”

Proceeding right on, Sun continued: “Then for the stallions’ tract, there’s the protective sheath, or ‘prepuce’, and inside that is the ‘penis’. The main components of the penis are the 'glans', then beneath the 'glans' is the 'shaft' of the penis. Finally, in the center of the shaft is the 'medial ring', a hard, highly sensitive ring of cartilage. Beneath the penis are two ‘testicles’, or 'testes', which produce 'sperm', contained within the ‘scrotal sack’, and inside the stallion’s pelvis are a number of accessory glands used to produce ‘semen’.”

Flurry, however, was completely confused. “...Huh?” she asked bluntly, not understanding all the weird words that Sun was using, “What’s a ‘pee-nus’? Do you mean your pee-pee?”

Clearly seeing that an adult explanation wouldn’t work in this situation, Sun decided to take a more practical approach. Getting so he was between Flurry’s legs, leaning over her slightly, Sun placed a hoof softly on her vulva. “These are your princess parts, or you can just call it your fillyhood or vulva,” Sun started, before moving up to the small cleft in her vulva, where her clit was, “and in here, there’s a little button, called your ’clitoris’ or ‘clit’, that can feel really good to have rubbed. This is what was coming out earlier when your fillyhood was moving. Then there's more stuff past it, but we'll get to that.”

As Flurry noticed that Sun’s willy had come out again, she nodded towards it. “What about that? I know you have a pee-pee, but that’s all that other stuff called?”

Sun nodded, giving a small stroke along his less-than-average-sized shaft, feeling his erection twitch at the filly’s observation of such a lewd act. “Yes, this is called my pee-pee, or willy, or stallionhood, though it’s scientifically called a penis,” Sun explained, before shuddering as he moved his hoof down his shaft to his medial ring, “This part especially feels really nice when touched, and you can just call it my pee-pee’s ring.” Sun got a giggle for that, Flurry thinking about his willy wearing a ring like her mommy and daddy sometimes did their wedding rings on their horns.

Finally, Sun used his magic to surround his sack and balls, giving a quiet ‘mmph’ at the sensation of his tingly magic on the sensitive orbs as he rose them for Flurry to see easier, “Finally, these you can just call my balls, though they’re also called testes. They’re REALLY sensitive to being squished though. Ponies have to be really careful with this part of a stallion, his balls especially, or they can really hurt him badly.”

Flurry’s eyes went wide at that, just the thought of hurting Sun, her best friend, making her sympathetically wince. “Oh...well I’d never want to hurt you…” Flurry said, almost afraid to even think about touching him there again.

“Well, you won’t hurt a stallion if you only gently rub or touch, just if you’re really rough and really try to hurt him. As long as you’re really careful, it will only feel good for him.” Sun comforted, seeing Flurry’s tension reduce at that.

“Oh, OK. Wow, here you have all this cool ‘pee-nis and balls’ stuff, and all I have is this boring fillyhood.” Flurry said, giving her nethers a prod and shivering at the tingle it sent through her, her small pink clit winking once in reaction. For some reason, whenever Sun had his stallionhood all big like this, Flurry couldn’t help but feel her parts getting a little more moist and sensitive, it feeling really good to touch herself down there while smelling Sun’s scent; his musky, stallion-y scent mixed with his distinct odor that only he smelled like. Something she really liked about him.

“Your princess parts…” Sun started, looking slightly indignant that Flurry would say such a thing about such a beautiful part of herself, “...are not boring. They’re beautiful, just like the filly they’re a part of.” He watched Flurry rubbing her fillyhood experimentally for a while, her large wings erect at the sensations. Feeling his penis somehow growing even harder at such a sight, he noticed that a small squirt of fluids came from her suddenly, seeing her panting and tensing up, her clit winking rapidly as her hoof delicately rubbed above its hood. As it only lasted a few moments he knew it wasn’t likely a full orgasm, but perhaps a mini-orgasm.

“I-I’m sorry!” Flurry suddenly exclaimed, even as she was recovering from that intense burst of sensations she’d just felt and noticing the wetness on her hooves and Sun’s bed, catching Sun completely off guard. As he looked up from her hoof and pussy to her face, he noticed her eyes glistening with unspent tears, ”I didn’t mean to pee! I just...it just...it felt really good to rub there, and, and…!”

Sun, before he’d even realized it, had grabbed Flurry in his hooves and hugged her tight to him, softly hugging her to his chest and shushing her soothingly, gently rocking her until she calmed down. “It’s OK Flurry, you didn’t do anything wrong, and it's not pee. It's actually really lovely I got to see that!” Sun said after he’d laid her onto her back on his bed again, smiling to show her that everything was OK and that he wasn’t mad at all, “When a filly squirts like that, it just means she’s feeling really good in her fillyhood! Plus, that thing you were doing with your fillyhood, that winking your special button did...stallions really like watching when that part comes out too. I know I do.”

“So...you like when my princess parts...move?” Flurry asked, getting a nod from Sun.

“I really do. It looks really nice to me, and makes your princess parts look even more pretty than they already do.” Sun said, earning a heavy blush from Flurry as she looked away shyly even despite everything.

“Why did it feel like my lower tummy was getting all tight and...squeeze-y when I rubbed my princess parts? It felt really good, and then that...stuff came out!” Flurry asked, even still feeling the aftershocks of her first mini-orgasm tingling in her. “I never felt that part of my belly move before now…”

Sun smiled and nodded. “Yeah, that’s your ‘vagina’, which is where your fillyhood opens into. That's where a stallion puts his pee-pee and it feels really good for both. From what I know, it really likes to be opened up and to squeeze on a stallionhood.”

New worlds were opening for Flurry. “Does it feel even better than...what just happened?” Flurry wondered, looking in wonder now at her lower belly, now knowing that beneath that innocent curve was her ‘vagina’.

“It...can. If you want, I could make you feel good, even without my penis.” Sun offered, and the second he did, he wondered why he had. He’d just propositioned getting a filly off!

Flurry, without a thought, spread her legs wider and left her whole little fillyhood on display to Sun, making his breath catch in his throat at the beautiful sight of her so openly presenting to him. “I think…” Flurry said, before her lips then winked open and clit peeked out, making a tingle go down Sun’s spine at the sight, “...yay, I did it! I did the thingy you said you really liked!”

Sun, seeing Flurry wink at him of her own volition, felt his cock flex and slap his underbelly, bringing Flurry’s attention to it again. "You can touch me down there again. I really like it." Flurry said, spreading her back legs a bit more. Permission given, Sun placed his hoof at Flurry’s small slit, which was swollen with her desire, finding it was slippery with her normal, slightly yellow lubrication, as well as a smaller bit of white; the latter was most likely her filly-cum, proving that she’d had at least a small orgasm to her own hoof. Raising his hoof to his nose, he sniffed deep, smelling the scent of a very aroused little filly; more specifically, his little Flurry was horny.

“I...really like it when you do that with your cute little filly-nub,” Sun said, his tone becoming more husky as his own arousal grew and Flurry’s pheromones started to cloud his mind. Without another thought, Sun started to rub his hoof over Flurry’s fillyhood, earning a gasp and an upward shift of the hips to grind her foalhood into his hoof. He felt her clit winking steadily as he gently rubbed the edge of his hoof between her pussy-lips, feeling her pushing up into him, her hips instinctively grinding along their source of pleasure. Sun was only too eager to show the eager little filly just what sex felt like.

Flurry, meanwhile, was in awe at how different Sun’s hoof felt than her own, so much bigger and able to touch every part of her little mound at once. However, all too soon, the sensations ended as Sun removed his hoof from her parts again, giving it another shameless sniff as he took in the filly’s musk once more. That scent, combined with the scent of Fleur’s passive estrus scent still permeating his room, only served to drive Sun’s lust that much higher.

“Why’d you stop…?” Flurry asked with a bit of a whine, having very much been enjoying the sensations of Sun rubbing over her, before she noticed Sun was still sitting, his stallionhood facing her.

“OK, your turn to make me feel good now.” Sun said simply, leaning against the headboard as he shifted to a partial-lying position, allowing his stifles to open wide and leave his whole package to the filly’s disposal. “Do whatever you want to my penis, but remember to be gentle...and no biting. I’ll let you know if you need to stop. Do a good job and I’ll give you a surprise.”

Flurry nodded and stood, approaching that large, somewhat intimidating ‘stallionhood’ from Sun’s right side now, getting a profile of the member. Tentatively, she placed one of her small hooves on it near the middle, near that ring-thing Sun had mentioned before. Immediately Sun responded, giving a quiet moan as his hips shifted upwards, his member jerking a bit. “I’m sorry!” Flurry yelped, jumping away and nearly looking in tears again, “I didn’t mean to hurt you!”

Once more Sun reached over and placed a hoof on her shoulder, rubbing soothingly. “It’s OK Flurry, it didn't hurt me at all,” Sun comforted, smiling at her, “In fact, it felt pretty good! It’s like...it’s like how my hoof probably felt on your foalhood. Tingly and nice, right?”

“Tingly and nice…” Flurry parroted, nodding, before gaining the courage and now rubbing his member again between her two hooves, then again, wanting to make Sun feel as good as he’d made her feel earlier.

Sun, meanwhile, was restraining himself from outright thrusting as hard as he could into the filly’s hooves, feeling a pleasure that his own magic or hooves couldn’t bring and making this feel way better than anything he’d ever felt before. His member was rapidly throbbing now with each stroke, pulses of his precum painting his underbarrel as they spurted out.

“What’s this?” Flurry asked, now only pumping with one hoof and holding up another, shining with his precum.

“That’s...something stallions make when they’re feeling really good, just like how you make juices too when you’re feeling really good.” Sun explained, getting a nod from Flurry, as well as seeing her smile.

“I’m...making you feel good,” Flurry said with a smile, beaming at the idea of making Sun feel pleasure, redoubling her efforts and feeling him continuing to pulse between her hooves. Suddenly, Flurry started licking along his flare on a curious impulse, tasting his pre, and finding she rather liked the taste of the lightly musky, if slippery, substance. Sun was meanwhile savoring the feeling of her small, warm tongue licking over its head. She tried to put more into her mouth, but had to suffice with only half of her mouth covering his flared head, her mouth too small to allow anymore in.

After a while of this, Sun gently removed Flurry’s hooves from his member as the sensations were starting to overwhelm him and his flare was starting to grow even more, knowing he’d cum soon if he didn’t stop her. “OK, you did great! You made me feel really good,” Sun said, getting another smile from Flurry, “I know of another way I could make you feel even better.”

“OK!” Flurry said, nodding, “What is it?”

Sun couldn’t help but feel another pang of guilt as she said that, unable to help but feel as though he were manipulating this filly for his own carnal desires. “Flurry, you don’t have to do any of this. You know that, right? I’m not making you do it.” Sun said, wanting to test the grounds a bit, to see if Flurry was simply following the orders of her guardian rather than doing something she chose to do.

“I know. I really like this though!” Flurry replied, still smiling, “It makes me feel really good, and I like making you feel good too and...I...I like you a lot.”

Feeling at least a small bit of moral relief that he wasn’t forcing this, Sun nodded. “OK,” Sun said, rolling over so his stallionhood pressed into the cloud mattress, his eyes looking into her eyes before then focusing on the two small slightly-darker-pink nubs that were her teats poking up from her lighter-pink fur, getting an idea, “Roll over onto your back like I was, then I’m gonna make you feel really, really good for your reward.”

Flurry nodded, doing just that and clenched her eyes shut. She entirely trusted Sun, and she’d liked everything so far. If she could feel even better, she saw no reason not to let him do whatever it took to do make her happy.

"Ready to feel good?" Sun asked shortly after Flurry got comfortable, getting a nod from Flurry. With both now in position, and her consent given, Sun first gave one of her small nipples a soft lick, getting a quiet, muffled gasp from her, followed by a giggle. Meanwhile his hoof made its way to her pussy again, slowly moving his hoof's edge up and down her slit, the simple but steady movement making her squirm as he rubbed it between her elastic lips.

Sun was rewarded with a shudder as Flurry tensed up more, her pleasure spiking higher at the lovely sensations of Sun’s tongue along her sensitive teats, giggling at the tickling sensations at first, her arousal already high from the earlier rubbing and his pheromones running through her. It wasn’t long before the sensations grew from tickles into...something more nice feeling.“T-That tickles Sunny…” Flurry said, but instead of just laughing, she gave a quiet moan.

Sun stopped licking, looking up to her face, and only saw lidded eyes watching him lick her and the expression of a very pleased filly. “Did you want me to stop?” Sun asked, but instead of getting a verbal answer, Flurry simply pushed her hips back into his rubbing hoof, her cute little clit giving an eager wink. So he continued.

“D-don't stop! T-tingles!” Flurry managed to sputter out after a while of Sun licking and rubbing her, her voice drunk on pleasure. Sure, it had felt nice earlier when she was rubbing herself and got those little tingles, but this blew that right out of the sky. She felt something big building up in her, grinding harder against his hoof on instinct as she felt the tension rising.

"S-Sun...something's...nice feeling...getting bigger!" Flurry whimpered, grinding back more eagerly, Sun now focusing on her clit's cleft more and getting her to frequently wink now.

That announcement only encouraged Sun on, making him increase the tempo of his movements, instinctively working to make his young mare ready for him. Ready to be bred by him. Sun looked up at Flurry’s face briefly as his hoof kept working on her slit, seeing her virtually glowing with pleasure, her lips pursed and eyes squeezed shut, clearly enjoying the feeling quite a lot if the quiet little whimpers were anything to go by.

He continued rubbing her, now constantly winking clit rapidly with his hoof-tip, his tongue trailing between the small valley between her teats before capturing the other nipple. He suckled on it for a while, separating with a loud 'pop' of breaking suction as he pulled off of one. Sun felt the semi-firm nipples quickly harden as he slathered them with his warm tongue, savoring the feeling of them getting hard because of his ministrations.

He enjoyed the taste of her salty sweat, the floral scent of the lavender shampoo, and of course the sweet ambrosia of her own unique tasting filly-fluids that had drizzled down from her pussy earlier, the little taste only making him want more. He felt the small ring of bumps of her areola raised around her nipple, feeling their texture under his tongue as he ringed it, making his dick flex hard at the feelings.

He paused his licking to simply savor the sight of Flurry’s teats in the light of the dying day, Sun looking at the small teats, seeing the deep-pink nipples standing tall from the much lighter, saliva-matted pale-pink fur around them, seeing them protruding from the much smaller fatty deposits of her teats themselves. He used his other hoof to feel it in its entirety against the frog of his hoof. He only moaned as he thought of how much bigger they’d grow when she’d hit puberty and get pregnant, a healthy set of mammaries to feed her future foals with. Sun felt a hint of jealous of those unborn foals, getting to suckle on the matured teats of this mare.

When Sun resumed suckling her nipples and his hoof kept rubbing that magical spot on her fillyhood, Flurry felt her pleasure spike exponentially, half-screaming out her ecstasy as she started to tremble now as he continued to rub her convulsing clit. Sun licked over her teats for a while more, before he trailed downwards to give a long and deep lick around and inside her folds, just to sample the taste of an aroused foal, earning a wink of her clit into his mouth.

After getting a small taste, Sunburst returned back to her teats. Intense surges of pleasure joined the constant tingling throughout her each time his tongue hit found a nipple or her clit winked, making her tense up as he rubbed her two most sensitive spots at once, that tension in her belly building as muscles she'd never used before that day squeezed within her.

"S-SUNNY...I'M...IT'S...!" Flurry cried out as she involuntarily bucked her hips hard against Sun’s hoof and her hips arched completely off the bed, her newly-discovered muscles trying to pull its pleasurer deeper into her as she came. She started repeatedly grinding him against her swollen lips while she whimpered through her first full-strength orgasm, heavenly pleasure overwhelming her as she tensed.

Her whole body virtually convulsed as Flurry's passage's muscles repeatedly clenched down on themselves, her juices splashing against Sun's hoof. Her very thick, slightly-yellow filly-cum came out like a waterfall, squirting against Sun's hoof and some even getting onto his coat, sticking to it or dripping off thickly to the bed below.

Sun was meanwhile enjoying the feeling of Flurry's harder-than-ever nipples in his mouth as she came, grazing his tongue over the hardened aureola. As he heard Flurry cry out and grind harder against his rubbing hoof though, squirming and convulsing in her throes of orgasm, he moved his licking to her squirting pussy and looked up at her face, seeing in her expression the absolute pleasure that he was bringing her.

When she eventually calmed down, her orgasm finally waning even as he continued to softly rub circles over her clit with his tongue-tip, he gathered her fluids up onto his tongue, savoring the sweet flavor of the little mare's release, before swallowing. “You taste wonderful, my dear,” he said as she gave a puzzled look at his actions, but she simply couldn’t care what he did when she felt this good.

“Mmm, that...that was…what was that?” Flurry mumbled as she recovered, unable to even describe what she’d just felt. She was just feeling so utterly relaxed now, her little ‘filly-button’ still occasionally twitching in the aftershocks and her inside parts squeezing and twinging sometimes as well, all the tension and need from before gone now.

“That was called your orgasm, my dear, or ‘cumming’. That’s what happens if something touches a mare down there enough,” Sun explained, “Felt good, didn’t it?”

Flurry nodded and, while she was relaxing after her first, seemingly very intense, orgasm, Sun now knew Flurry was ready for him, her insides well-lubed now thanks to his efforts. After letting her rest for a while, he rolled over so he could stand up, his member hanging stiffly beneath him. “Alright,” Sun started, looking to Flurry, “now onto the main game. We’re gonna put my pee-pee inside your fillyhood, and it’s gonna feel even better than what you just felt, for both of us. Could you to lay on your back on the bed for me?” Sun asked, feeling like he was ready to explode without stimulation now, the scent and taste of an aroused filly still coating his muzzle and on his tongue.

“But…” Flurry said, looking at the comparatively huge phallus, feeling nervous. “...it looks way too huge!”

“No, trust me, I’ll make this work,” Sun said, feeling a small sense of pride at hearing his amazingly average penis called big, smiling softly. He knew a few spells that could definitely help with this, after all. Sun then climbed over the little filly, mounting her, and trying his best to keep most of his weight off of her. He moved her so that her croup was on the edge of his bed, his warm, hard stallionhood resting along her chest and belly as she laid on her back still.

Flurry glanced down...and noticed the huge thing’s tip was almost to her lower chest! “Um...S-Sunny...I don’t think it’s gonna fit…” Flurry whimpered, clearly intimidated at its sheer size compared to her, “I don’t know if my princess parts can...”

“It’ll be OK, I promise,” Sun cooed, feeling the underside of his stallionhood grinding against Flurry’ small, nearly hot fillyhood, loving the sensation of his first penile contact with a female’s sex. “It’ll be juuuust fine.” While he ground against her, he could feel himself sliding along her slick fur, between her still wet teats, feeling their hard nipples scraping against his member’s underside, her super-soft fur ticking and stimulating him in ways he’d never been before. He was mindlessly humping at this point, submitting to the sensations and the scent of an aroused mare fueling him on.

Flurry, meanwhile, wasn’t enjoying the grinding quite as much as Sun was. She was slightly struggling for breath as he weighed down on her despite most of his weight being kept off of her, but even still the tingling sensation of him sliding over and between her teats and clit hood was something she very much enjoyed, enjoying even more when her little pink clit would wink out and be grazed by his willy’s sliding. It felt nice, but she hoped it could change a bit to feel nicer for her too. “Sun…” Flurry forced out, “...you’re...squishing me…”

Immediately Sun dismounted her despite his instincts demanding the opposite, his forehooves clopping on the crystal floor as he stood on all fours now. So caught up in his breeding haze he had been that he hadn’t even considered Flurry’s comfort, realizing he’d indeed been forcing her down into the cloud mattress unintentionally hard. “I’m sorry, are you OK?” Sun asked the panting Flurry, unsure if that was because she was enjoying the grinding...or couldn’t breathe before.

“I’m...OK.” Flurry assured after catching her breath, her head swimming at the sensations still tingling in her nethers, “That felt really nice, your pee-pee against my fillyhood and tee-tees, but is there a way we can do that without you pushing me down like that?”

Sun considered the question, then nodded, climbing on the bed and laying on his back beside Flurry, with his member sticking straight up like a pole. “Flurry, I want you to come and sit on top of me. Then, you move your hips so your fillyhood moves along my pee-pee.”

Flurry nodded without question, doing as asked and climbing atop him, with Sun guiding her so she was straddling her legs so his member was between them, her forehooves resting on his chest for balance. “Good, now just start moving your hips like I was.” Sun said simply, getting a nod, and Flurry then started grinding her hips on instinct.

Flurry gasped at how different this felt, being on top adding a whole new perspective and sensation. She started sloppy, unsteady, and even would have fallen off of Sun more than once if he wasn’t carefully supporting her with his hooves. She loved when her little bump would rub against his member, each wink sending a snake of pleasure slithering up her spine, a heat starting in her belly. Deep down, Flurry wanted something...more. “Sun...my tummy’s feeling really warm…” Flurry mumbled out, meeting her eyes with Sun’s as he looked down to her, his expression one of mild bliss.

“That just means you’re really aroused, my beautiful little filly,” Sun said, seeing Flurry’s cheeks’ blush deepen even more from the compliment, “It means you’re ready for me to go inside you.”

“O-Ok…” Flurry said, feeling Sun’s hooves guiding her so she was mostly standing on her hind hooves now, squatting with his flare pressed to her virgin petals, his hooves wrapped around her hips and croup as he was now poised to enter the little filly’s virgin passage.

NOTE: This chapter was partially written by the commissioner themselves. Some of the content, therefore, is not written by me, and some of the fetishes in this chapter are also not shared by me.

“Are you ready? I'm gonna be using a spell to get rid of any pain this would normally cause so all you'll feel is some pressure and the good feelings. Is that OK?” Sun asked as his flare was pressed tightly to Flurry’s comparatively tiny vulva, his hooves around her hips and croup, keeping her steady as she was mounted on him as he lay on his back.

Flurry nodded and Sun then lit his horn, carefully focused on Flurry’s lower belly, before casting a pain-numbing spell as well as an elasticity spell. He knew a mare’s vagina was designed to stretch, but even with his smaller penis size, he knew she’d likely need help taking him. The pain spell meanwhile was designed to eliminate all pain for a long while, but didn't block other stimulation like pressure or pleasure. He wanted to do whatever possible to cause her the least harm, not wanting this to hurt her as some deflorations would.

“OK, it's done. Here we go.” Sun said after seeing Flurry nod, nodding himself. Suddenly, Sun pulled down on her hips while thrusting upwards, entering the little filly and both losing both their virginity at the same time—

—or would have. Instead, nothing had happened. Sun pulled down and pushed up again, only getting a little squeak and wink of the clit from Flurry, but couldn't get more than half an inch into her, even with the added magical elasticity. She was simply too tight!

“Ok, I'm gonna need to be a little rougher so I can get inside you. Just ask me to stop if you need me to stop.” Sun said, Flurry nodding her consent. Sun then pulled down and pushed forward harder, and harder, until finally he forced himself about two more inches into her ultra-tight and tiny, but very well-lubed, passage at once.

Flurry cried out at the pressure and stretching of being penetrated her first time, feeling a sudden uncomfortable, intense spreading inside of her lower belly. She felt like something inside of her tore when Sun pulled down on her like that, a strange, though not painful, spreading sensation radiating through her after it did. "W-what was…” Flurry exclaimed in panic, trying to get away from the weird, uncomfortable feelings on reflex by trying to pull her hips away, but Sun held her still. Instead of trying to get away for more than a few seconds, she quickly started grinding against him instead to sneak another partial inch into her as another instinct kicked in. One that told her that this was a good thing despite the weirdness, to bear with it and she would be OK. So she did just that.

Sun was meanwhile in ecstasy at the extremely tight warmth and wetness surrounding his stallionhood for the first time, pulses of strong sensation going through him with each squeeze of her extremely tight passage spasming on him, her body struggling to adjust to the substantial girth spreading her immature passage so sharply. Sun knew now that his magic or hooves could never compare to the real thing. A real mare, regardless of her age, was wrapped around his shaft, clenching and squeezing. So very warm…

“Sunny...this feels...so…weird!”

As Sun heard her, he was knocked out of his reverie. He looked up to see her strange expression. “Shh...shh, it’s OK. It’ll feel less...weird soon, I promise,” Sun said with utmost sincerity as he brought a comforting hoof to her cheek and caressed it, with her rubbing back into it in kind.

Flurry, meanwhile, still felt that strange spreading in her filly place. “Why...why did it…?” Flurry asked, her tone one of confusion.

“It always hurts the first time, especially given how...big my pee-pee is compared to your fillyhood, but it didn't because of my spell. You only feel the pressure and stretching of your insides opening like this for the first time, and it will never hurt again when any stallion or colt puts his stallionhood in you. It only would have hurt the first time, I promise.” Sun tried to explain, getting a nod from her.

“OK.”

Even still, despite feeling bad for having to make her uncomfortable at all despite knowing it would be way worse without the numbing, Sun stayed stark still as he felt her insides seemingly form-fit and gently ripple over his length, not wanting to make it worse. Meanwhile, a small inner ring just past her entrance was squeezing him with each spasm, as though it were tightly masturbating him inside of her. He saw a thick bulge inside of Flurry and noticed how it was very visible through her lower belly, realizing later that his member was so large inside of her that it was causing a significant stretching in her, his stallion-sized girth causing her filly-sized belly to slightly distend to accommodate it instead of the much smaller member of a colt her age.

Sun meanwhile glanced downwards and noticed a small trail of tinted-red fluids leak out of her tight passage and onto his pelvis, knowing it was the virgin blood of her now torn hymen, wincing at the sight of it. Despite all of that, It felt so…right to Sun though, to share this with Flurry. To share their first time together, and him to spare her the pain of being deflowered.

Flurry, meanwhile, felt the discomfort start to reduce the longer Sun stayed in her, her insides finally starting to adjust to their much larger partner, the elasticity spell helping immensely. Eventually Flurry’s discomfort faded, the feelings in her fillyhood morphing into the same feeling as when he’d touched her vulva and rubbed it earlier, but...so much better now. The spreading of her insides with his stallionhood was...it just felt so…”Your pee-pee feels really good Sunny…” Flurry cooed with her eyes glued shut, “It’s all big and makes my insides all stretchy...and tingly…and it’s all hard...and...and...it was really weird feeling at first but now it...feels...really nice...? How are you so...inside me?"

Sun simply laid there and let out a massive exhale as he enjoyed the tight insides of his first little filly. "Mmhm. It feels like your fillyhood is hugging me, but on my stallionhood..." Sun replied, and squeezing him she was. Her insides were like a vice, with him unsure he could pull out even if he wanted to until she loosened up some more. Testing the waters, he tried to flex his member, but it was as if her insides locked him in her.

“So, you’re OK now?” Sun asked, seeing Flurry’s uncomfortable expression change into one of pleasure, her hips starting to grind harder against him even with him embedded almost to the medial ring in her.

“It...it feels...I feel all warm and tingly inside now…” Flurry said, feeling an almost burning-like sensation in her tummy, just above where Sun’s flare was. It was kind-of unpleasant, but being stretched by Sun like she was seemed to make it all seem OK. Like this was exactly what was supposed to happen when she felt that itchy-burning feeling.

Sun meanwhile realized that her pussy had gotten a bit warmer around his shaft, her fluids more thick and profuse, but he attributed that to her growing arousal. “Mmm, I’m glad your insides are happy now…” Sun said huskily, his hooves releasing her hips and now softly rubbing up and down her flanks* beneath her fully-erected wings, from just under her wings’ downy under-feathers to her stifles where her cutie mark would be eventually, feeling her squirm at the sensations.

After rubbing her sides for a while, Sun’s hoof moved to Flurry’s belly, gently rubbing that bulge he made in her, able to identify each bump and ridge of his comparatively-massive shaft through her nearly-taut skin. Sun also noticed that with every twitch his stallionhood made inside her, he could clearly see her two tiny teats bounce in correspondence. Reaching up for a quick fondle, he noticed how they were still hard against his frog, before pulling away and resting his hooves on her for balance.

Flurry’s breathing increased to a slow panting, her grinds growing more insistent, and not a sign of pain on her face as she started to quietly whimper in need; a need she didn’t know a cure for. “Sun...I need…something...” Flurry mumbled, her hips still shifting, the feeling of his pee-pee inside of her, just jiggling around inside of her, a really nice feeling to her. But she needed something else. “More...something...more?” Flurry more asked than requested, as though she didn’t even know what she wanted anymore.

Upon hearing this, Sun nodded, seeing her closed eyes and blissful expression, knowing that she was feeling really good inside as she ground her soaked crotch all over his medial ring. Her small pink pleasure pearl peeked out against it all the while, turning him on that much more. “OK, now I’m gonna pull it out…” Sun said, getting a whimper from Flurry.

“No...but...but…” Flurry fumbled with her words, not knowing why, but knowing deep down that she really, really wanted Sun’s willy to stay right where it was, deep inside her.

“Shh, don’t worry, I’ll put it right back in, I promise.” Sun said, earning another displeased whimper from her as she kept trying to grind even as he softly grabbed her in his magic and started to lift her from his stallionhood, with her all the while trying to push back down and grip at his barrel with all her might.

“Please Sun...I...I need it…” Flurry whined, feeling as though each millimeter he slid from her was a little part of her he was taking away; as though it was something vital to her existence that he was sliding out of her now-soaked inner walls.

“It’s OK...I promise...I’ll p-put it right back.” Sun said as suddenly the scent of fertile mare grew stronger in the room, only adding that much more to his lust. He didn’t know why the passive scent was now growing so much stronger since the rug containing Fleur-de-Lis’s fertile estrus scent was locked away in his closet in a magic force-field, but in his altered state of mind he simply couldn’t care, only thankful for it making the sliding of his member against Flurry’s nearly-hot vaginal walls feel so much better.

Suddenly, Flurry cried out in pleasure as Sun, as promised, started to lower her and push his comparatively-massive willy back inside her slowly. She felt each inch, bump, and texture of his member being introduced back into her, the warm hardness she felt that her whole life depended on stretching her open again. “Ooooh Sun…” she cooed, her whole body tense, but a good kind of tense, her inside place where Sun was especially feeling tight. “...you’re...it’s…”

“Y-yeah, it feels good for me too...you’re really warm and tight inside. J-just what a s-stallion’s pee-pee loves.” Sun said, meanwhile meeting his medial ring to the outside of her vulva again, feeling her shudder atop him as another wink pressed her pleasure button to his ring again. A quiet, adorable whimper of pure joy coming from her, along with a small squirt of her filly juice adding to the puddle surrounding his rump on the bed.

Sun smiled as he felt her insides growing tight and rippling around his dick again in the telling sensations of his mare’s orgasm, feeling her winking constantly and trembling as she came again on just the second thrust. “S-SUNNY!” Flurry cried out in an impassioned tone, her hips grinding against his medial ring as her instincts took over, her insides doing their best to milk him of his life-giving sperm.

Sun, meanwhile, was fighting hard to hold off his own orgasm as Flurry’s passage rippled hard from his member’s ring to tip, feeling – and watching through that large bulge he made in her growing even bigger – as he started to flare up, feeling her already crushingly-tight passage growing almost painfully so around his flare, feeling as her forceful squirts of filly-cum dripped down over his testicles. He also felt as his flare somehow went even deeper into her, feeling a tight, puckered ring against his flare; meeting a wall of sorts. Sun knew now that he’d finally met her canal’s very end; her cervix.

“S-SUUUUUUUUUN~!” Flurry cried out as she felt that growing feeling in her, feeling as his flare pushed against something super-duper deep inside of her, it only driving the intense tingling feelings already wracking her to become even more so. Her whole body convulsed as she collapsed onto Sun’s chest, her front legs giving out from the sheer pleasure, and a complete downpour of thick, slightly yellow foal-cream absolutely covered his entire pelvis as a result of her sheer pleasure. With every slight movement, extremely wet, loud squishing sounds echoed throughout the bedroom as a result of their intense pleasure and Flurry’s instinctive grinding. At this point, her back legs were only being supported by Sunburst’s shaft, which was completely bottomed out against her tiny cervix.

Sun, meanwhile, knew he’d cum soon if he didn’t do something, so with his last bit of sentience, he cast a spell on his flared member, blocking out some of the sensations of her rhythmic inner flexing and calming his throbs, his orgasm receding again. Sun, after all, wanted Flurry’s first time to be unforgettable, as well as his own. For now though, he waited for Flurry to calm down from her high, feeling her inner squeezes slowing down as well as her trembles, her breathing starting to resume a more normal pace as opposed to the ragged gasps she took in while her orgasm dominated her.

After thirty seconds of the best feeling she’d ever felt before, even better than what she’d felt with Sun’s hoof rubbing her down there, Flurry finally felt all tension leave her body, a limp puddle of pleasured filly now panting atop Sun, the source of those wondrous sensations she’d just felt. Sun watched as the tiny pink filly squinted while she opened her clenched eyes. “W-wha...wazzat?” Flurry mumbled out, her muzzle buried in Sun’s chest fluff, only her barely-opened eyes meeting his being visible, “W-why do you...your pee-pee top...s-so biiiig…?”

“T-that’s…” Sun replied in a deeper-than-average, husky tone, feeling as though he had just cum despite holding it off, his head still feeling light as air, his flare still like a rock inside of her, “...that’s what happens when a s-stallion’s feeling r-really good from a m-mare’s insides and is ready to c-cum...their f-flare gets all big to keep it all inside.”

“C-cum? Keep 'it’ inside? You mean their pee-pee?” Flurry asked, clearly confused. Sun had never used that term before, after all.

“It’s...it’s another way of saying ‘orgasm’, which is what you just felt. The really good tingly feelings when your insides squeeze down without you doing it.” Sun said, getting a slow, dazed nod from Flurry, who was indeed still feeling the after-effects of said orgasm. “When stallions get their orgasm, they get all big like that and...well…” Sun said, “...well, they squirt what makes the foal inside the mare. I’ll get my orgasm soon too, and you can see then.”

“Oh...OK…” Flurry mumbled out, sure she’d agree to almost anything at this point with how good she felt. Sun still felt all big and deep inside of her, his thick flare putting extreme pressure against something really far in her. Flurry felt him deep inside her belly, making it puff out and appear all big and nice feeling, while making the feelings inside her head tell her this was so good, so right; to make him keep going in and out and in and out. “...you can...keep doing that slide-y thing in my p-princess parts…p-please?” Flurry asked, no small amount of desperation in her tone as she still felt her insides squeezing and squeezing on the hardness embedded in them, as though trying to make it do…something. Something that she didn’t know what it was, just that her inside parts needed it.

Sun thought for a moment, before gently pulling up on her and sliding himself out, with her meanwhile trying to force herself against his superior strength, trying to keep that hard, warm, big thing inside her as that little kinda-voice inside her head told her to do. “Sunny...please...I...I need that…” Flurry mumbled out, but Sun was stronger than her, and she gave a displeased whimper when his thick flare was forcefully pulled from her with a loud pop from breaking suction, leaving her inside parts feeling utterly and uncomfortably empty, “...please...pretty please...put it back!” she said emotionally, fighting back tears from the multitude of emotions currently swirling through her mind and a deep discontented feeling that she knew that only him putting it back in would fix.

After he pulled out, Sun glanced back and noticed that his thick pink member bobbing beneath him, fully flared, now had a noticeable yellow hue to it, still completely covered in Flurry’s orgasmic fluids. So covered in fact, he would think that was his member’s normal color if he didn't know otherwise, the thought alone nearly making him cum all on its own; how he’d pleased her so much to make her gush all over his phallus like that, and so much too. How she'd marked him as hers.

“Please...please Sunny…” Flurry begged Sun, her hips trying to push back against something, anything, her clit winking rapidly and making her fluids drool out more as the burning, uncomfortable empty feeling grew every second he was outside of her. Sun thought it was almost like she was in a full-blown estrus from the desperation in her tone, how swollen and red her fillyhood was, and how thick her fluids were, but he knew she was way too young to be in heat. Surely it just wasn’t possible for a filly to go into heat at her age, so he simply dismissed it as her just being really excited and intense for her first time.

“It’s OK, I promise I will. I just wanna try putting it in you in a different way now.” Sun said, only getting a small whimper from the sexually-desperate little filly. Using his magic, Sun positioned Flurry so that her chest pressed to the cloud mattress, her forehooves folded comfortably under her chest, and her cheek pressed to the cloud with her muzzle's side flat against it. Her rump meanwhile was high in the air, her messy and soaked tail flagged over her back and to the side to the much larger stallion behind her on instinct, the now very unpleasant hot and burning-tingling sensation in her belly and vulva making her clit wink rapidly. “You’re so beautiful down here Flurry…” Sun said, only getting another wink from her, her hips slowly swaying as her cheeks turned a bright red.

“P-please Sun...I need it...your big-end thingy all the way in me to my back thing…” Flurry said, her voice deep and sensual, a tone she’d never used before but that felt so right to use now, “I want your...your pee-nis all the way inside my belly...please...”

At such a lascivious offer, Sun lost control of himself and instantly mounted the little filly, earning a surprised yelp from her as his underbarrel suddenly ground against her croup, sending a strong shock of pleasure up her spine. “Y-YESSSSS!” Flurry shouted out in a half moan, half whinny, her hips pushing back, desperately trying to find its instinctive mate in the form of Sun’s penis.

“F-Flurry…” Sun grunted in some frustration as her hips were swaying rapidly, up and down and to the sides as he was trying to line up to penetrate her again. His glans tapped randomly against her backside and between her teats, or even sliding over her back and along her croup, smearing it all with his pre-cum and her fluids but achieving nothing but frustrating them both more. Finally, with a frustrated grunt after some seconds of this, on some deeply-rooted instinct, Sun reached back, stretching his neck a bit downwards to reach Flurry's head. He then suddenly bit down on her upturned ear.

Flurry gave a quiet, involuntary whimper and stopped moving instantly as that instinctive sign to stay still from a dominant pony was obeyed by her over-enthusiastic body, that slight pressure sending a message to her brain to stop trying so hard and just let what she so desired happen. To let her stallion do what he needed to do in order to get back inside her body.

As Flurry stayed still now, even though her tail, which was wet with her filly-juices, was still impatiently flicking his side, Sun concentrated and let his instincts guide him now that he wasn't actively being rushed or sabotaged by his over-eager filly. Finally, now that he had a moment to concentrate, his first few taps missed again, even with Flurry trying to help by gently shifting her hips towards his flare’s taps on reflex, but soon enough he felt a certain wet warmth give to his next tap more than her plush rump, that sensation making them both gasp. He'd found it again. He'd found her winking, drippy, extremely tight entrance.

Instantly, without the will to restrain himself anymore, Sun’s haunches lurched forwards, but once more Flurry’s tightness foiled his first thrust. He tried twice more, but her whole body only slid forwards at the force, her chest grinding against the bed as she groaned in pleasure at the sensations. “P-please...i-in me…” she whispered, cute desperation in her high-pitched voice, and that was all it took. Lighting his horn, and knowing she'd likely be alright with it if she were in her right mind, Sun gently pressed Flurry to the bed with his magic, bit the mattress as though it were a mare’s crest, and RAMMED his hips forwards into her depths.

Flurry yelped and squeezed her eyes shut tight when Sun’s still-swollen flare was forced inside of her, a less intense pressure than before welling up inside her, her immature muscles again being pried apart so suddenly by something much too big for them. While it was less intense than before, a definite stretching sensation was noticeable at first to the small filly, but now that feeling merged into a mix of weird and tingly, before it then fully faded into that wonderful tingling again much faster than before. Her wings were now fully outstretched against Sun’s sides and flapping stiffly at the sensations, her feathers gave Sunburst a light tickle,stimulating him that much more alongside her ultra-tight muscles clamping down on their partner in pleasure again in a welcoming hug.

“S-SSSSunnyyyyy~” Flurry hissed out as that 'this is right’ sensation flushed through her, her mind telling her that this was exactly what she needed; that this was the best thing ever and how she still desired more, but something else needed to happen to make her totally satisfied. She let out a quiet squeak as her hips started shifting as Sun stayed still inside of her for a few moments, him not daring to move with the vice-like grip her princess parts were putting on his stallionhood as she rippled her muscles along his penis in the same motions as before.

Sun remained still, savoring the less intense milking motion of Flurry's insides - much less than Flurry's orgasm, but still felt wonderful to him. After letting his mare adjust again, Sun started to slowly shift his hips against her, his magic still holding her down gently so she wouldn’t slide again, and felt the extremely pleasurable sensations of her unbelievably tight, ribbed fillyhood rubbing along his shaft as he pulled out. He felt her hips pushing back desperately despite his magic holding her to try and keep it inside her, feeling her winking constantly as her ultra-thick fluids drooled down his balls, sticking to them or accumulating between them on the mattress in a puddle of precum, filly-cum and feminine liquid lust. Her small, pink, winking clit was now stained to be nearly yellow, her thick cum sticking to it with a thick string hanging off, swinging back and forth with each rough hump.

Flurry let out a quiet ‘eep’ as Sun pushed in hard again, defying her tightness with his forceful thrusts, a loud, wet schlick sounding out as that large dollop of Flurry’s and Sun’s accumulated fluids was then forced out and onto the already-soaked mattress. She continued to make an assortment of quiet ‘eep’s, moans, or even quiet whinnies as Sun started a slow, hard-fought rhythm, getting deeper and deeper with each thrust, before finally bottoming out against her cervix again, feeling it shifting back a bit as though to kiss his flare.

Despite the amount of pressure from him hitting her end like that again, Flurry felt his part so deep inside of her tummy that it felt like his thick top part was hitting her belly button, sending another spike of pleasureable pressure through her each time he hit it. “S-Sun...what’s…” Flurry practically cooed out, the 'tickling’ feeling flooding through her full force each time he hit so deep in her like that; like he was supposed to be that far inside her.

“That’s...your...cervi—ohhh Celestia…I’m at your cerv—c-cervix.” Sun forced out as his lust-addled mind finally let him realize that – that he was at the absolute depths of Flurry’s immature passage – barely able to given the sheer pleasure Flurry’s squirming and squeezing caused him. With sweat pouring down his forehead, Sunburst lost any semblance of sentience, running entirely on the instinct to breed now. His feral thrusts grew that much more rapid and rough as he heard the cries of pleasure coming out of Flurry – from his broodmare – in quiet ‘ah’s, him feeling her milking him so wonderfully inside. Feeling like he was breeding his young mare just the way he was supposed to be, getting ready to fill her young, and thus undoubtedly infertile, womb with his hot, virile cum soon.

“W-what…is...my…‘c-cerkicks’?” Flurry asked, a foal’s curiosity showing even now in the middle of the intense sensations of her first breeding.

“I-it’s...a...I'm...all the way...i-inside you…” Sun barely stuttered out, not worrying about the mispronunciation, too enamored by the intense tingles rocking up and down his spine to think about much of anything besides keeping his hips pounding into the little filly princess. “As f-far...as...your...princess parts can...go...” As he said that, as though those words made something click in his animal mind, he made his flat flare mash up against her deepest depths, forcing harder against that ultimately tight ring; the final barrier to her womb."...well, almost."

Sun kept rutting Flurry as hard as he would into a fully-grown mare, his magic holding her steady so she wasn’t constantly sliding forwards with the force and her not protesting being held down at all, too focused on the pleasure he was bringing her. Flurry felt as his penis lit up her inside place with each thrust, intense surges of stronger pressure and pleasure going through her when his flare’s pointed bottom portion rubbed perfectly into a special part of her insides.

Sun ramped his thrusts even harder as his horn lit, his magical force rolling down Flurry’s chest then belly, seeking ever lower. As it swiftly reached its destination, Flurry let out a surprised, and rather adorable, shriek as the sensations coming from her nethers suddenly doubled. That tingling sensation of magic encapsulated her tiny little nipples and clit, making the latter start bulging in and out of its hood that much more at the stimulation, practically touching Sunburst’s testicles, and it would have if he was able to fit himself inside fully. As his magic started playing with and pinching the nipples of her small, foal-sized teats and her clit, Flurry’s legs were fully trembling now, more so than before, her whole body nearly vibrating beneath the rutting stallion above her.

“S-Suuuun~...” Flurry moaned out, her head thrashing on the mattress, everything coming to a climax now. She wished she could wrap her legs and wings around her stallion’s croup and keep him deep inside of her, even if she didn’t know why. The feeling of her insides growing that much tighter, that sense of waning control slowly morphing into that powerful sensation of before, was coming again. “...S-Sun...I’m…I…T-TINGLES!!!”

As Sun heard Flurry say that, he felt her insides instantly growing tighter and starting their powerful, rhythmic inner flexing in her third orgasm as he started to flare, earning a pained groan from him at the further tightness that caused. She meanwhile looked down between her forelegs to see her belly bulging even more obscenely, practically able to make out every feature of his member inside her, almost perfectly outlined in her tight body. From her view, it looked as if he was about to go right into her stomach!

“So...so...d-deep a-and t-tight…” Sun muttered, but his instincts weren’t satisfied. He wanted to go deeper still; he wanted to get his medial ring in at least. Starting to somehow ram even harder into Flurry, he felt his swollen flare slamming against her cervix hard, their position allowing him to basically piledrive down into her. The little ring was utterly impenetrable at first, but from the constant barrage and by some other factor, it eventually loosened, before finally Sun’s next thrust made his thicker medial ring slide into the near-infernal insides of the filly...and his flare going into her womb itself.

Flurry felt the pressure of Sun going even deeper into her, delirious with the intense pleasure of him going so deep, her eyes rolling back in her head as she helplessly rocked her hips against him while his stallionhood slammed into the back of her womb. **Sunburst felt the complete texture of her insides change as he now was past a barrier that squeezed him beyond her outside vulva. It was almost as if his member’s head was squeezed into a smaller shape due to the sheer size difference and tightness of her womb’s entrance. As he continued to rock his hips with complete bliss, his member was pressed extremely close to Flurry Heart’s bladder, with only a small bit of fleshy walls separating the two caverns unknowningly. As Sunburst rocked his hips inside the tightest thing he had ever experienced, Flurry took a measure of extreme realization as she felt the need to go potty instantly.

“Um…um... Sunburst?” Flurry asked, knowing the emergency she was now feeling in her nethers. Not receiving a reply, she opened her eyes and glanced upwards at Sunburst to tell him of the dire situation she was now coming to. Looking at the stallion currently rutting her, she saw him hunched over her small body with his eyes completely glued shut.

“S-Sunny…I…I..need...to...go potty…now!” Flurry exclaimed towards the stallion. Still in a mind of his own rutting the hottest and tightest thing of his life, Sunburst completely ignored Flurry’s request and kept rutting her senselessly. In a last ditch effort to not go potty all over the bed, she tried her best to squeeze her back legs together to hold it in, but that measure proved to work against her as Sunburst stallionhood rocketed against her now tighter hole, his next thrust pressing directly into her bladder. Unable to hold it any longer, Flurry was in borderline tears as she couldn’t hold it any longer and let out a stream of light yellow and clear pee, combined with the thick juices of her filly-cum.

Feeling more wetness surround his member than a normal orgasm would cause, Sunburst glanced downwards to see the constant stream coming out of his foal with each out-thrust, thinking it was only her filly-cum. A mix of shame and fear for the consequences rolled through her meanwhile, and she was about to say something, when the tingles started to completely take control of her body, causing her to completely forget the naughty act of wetting the bed, herself, and on Sun as her eyes rolled back inside her head. **

Flurry’s orgasm raged on even through the embarrassment, though she couldn’t really care with how good she was feeling. Her body was tingling all over, every inch of her electrified like that one time she’d accidentally flown into a storm-cloud, but not painful at all like that had been, instead making her feel like her whole life had led up to this; that this was what she was supposed to do. That she was supposed to be bred by her stallion.

Sun, meanwhile, could hold off no longer – the feeling of Flurry’s walls contracting around his shaft and medial ring, her womb itself hot around his swollen flare as it pulsed huge gobs of precum into her, and finally her cervix squeezing just beneath his flare nearly tight enough to cut off circulation – finally tipped him over the edge. Sun gave a very dominant breeding whinny as that tension in his pelvis snapped, his hips lurching forwards a final time.

Flurry felt a wet warmth slowly pooling inside of her tummy now, making that warm feeling grow with each of Sun’s member’s strong twitches along what felt like her entire lower belly. It was...nice. It felt comforting, like he was giving her insides a hug on a cold winter’s day. It felt...right. With each pulse from his flare shooting into her, Flurry felt the itchy-burning sensation that had been growing since he’d first put it in her growing less and less intense, until finally, it was gone entirely. She was puzzled, but instead was so caught up in the satisfaction and feelings of her waning orgasm, of the warm semen inside what she didn’t know was her womb, all being all locked inside by Sun’s massive flare as he even still impotently tried to thrust his hips against hers.

Sun, meanwhile, felt as the first burst of his foal-cream gushed from him, chomping down on the mattress hard as he could as he completely lost control of himself. He felt himself humping even still despite his penis not being able to move at all due to the diamond-crushing tightness of her womb and cervix, his instincts urging him to stay as deep as possible. Flurry reflexively milked him dry, each squirt after squirt of thick, virile cum unloading directly into her womb and surrounding his flare in its thick warmth, Sun finding it felt at least a hundred times as good as when he squirted into the air when he stroked himself; the feeling of something wet, warm, and alive squeezing around his shaft as he came was something he’d never imagined would feel so good.

After a number of seconds of feeling Sun pulse-pulse-pulsing inside her, Flurry’s belly began to expand as more and more semen was forced into her uterus, his flare acting as the mating plug it was as it allowed nothing to escape. Flurry started to feel slightly queasy as she was filled more and more, her swelling womb pushing up against her stomach. Her tiny inside space was barely able to fit it all, but still Sun came more and more into her insides, his magic holding her in place so she could take it all.

Finally, when her lower belly looked like it had a small grapefruit in it, Sun finally stopped humping against her as his orgasm faded and ejaculation tapered then stopped, leaving only an exhausted, drained, and extremely satisfied and relieved stallion and filly in its wake. He still felt her vice-like pussy, cervix, and womb around him, working in its instinctive way to draw his seed deeper inside of her; the minor upwards contractions along her entire tract from base to flare working to draw his sperm into her oviducts to meet any waiting eggs...which surely didn’t exist given her age, and the fact that she wasn’t even close to the age where she would hit her first heat.

His orgasm finished, Sun went to dismount Flurry...only to drag her along with him, causing her to yelp. “Sun! That feels so weird!” Flurry whimpered, getting a soothing kiss on her neck.

“I’m sorry...it’s not supposed to be stuck like this. I think you’re just too tight still! Try to relax.” Sun said, the tightness and mild milking sensations on his post-coitis boner getting to be somewhat unpleasant.

Flurry’s head was still all fuzzy from that extremely powerful release she’d had and the instinctively soothing warmth and feeling of his cum inside her, but did her best to try to relax her muscles 'down there', trying to find the right muscles to control. When he tried to pull out again while holding her in place with magic as he felt her muscles loosen slightly, Sun only earned another quiet whimper and yelp from her. He was well and truly stuck inside of her, he now realized, her cervix having basically sealed his swollen flare into her cum-filled womb.

“I...I guess we’ll just have to wait for me to get soft again.” Sun said, with some dismay, rolling so he was now spooning with Flurry as he laid on his side, still trapped inside her.*** As he laid there, trapped by the penis within the little filly, Sun started to feel some regret for what he’d done as the realization kicked in. “I’m so sorry for doing this this to you Flurry...I just...I…” Sun stammered, unable to come up with an explanation.

Sun’s mumbling was interrupted as he felt Flurry’s wing drape over his side in the manner of hug, hearing a contented sigh from her. “Sunny, I don’t know why you’re so sad. That felt really good except for feeling a bit weird too, and now my insides feel all warm and squishy with your boy-stuff! It's so cool!” Flurry said, bringing a hoof up to a quite large bulge swelling out from her midsection, making her appear to be a few months pregnant with a foal.

Knowing there would likely be no consequences to this provided Flurry didn’t tell anypony about what they’d done, Sun sighed. “Alright, but you have to listen to me sweetie. You can’t, under any circumstances, tell anypony about this game, OK Flurry?” Sun said, feeling Flurry squirming against him, her back grinding against his underbarrel as her clit winked a few final times, practically kissing his testes.

“But...but why not?” Flurry asked, clearly confused, “It was a really fun game! I wonder if Daddy would want to play it with me!”

Sun’s eyes widened and his penis twitched inside of her at the thought of Shining Armor mounted up on his daughter, humping away with that massive black shaft - easily double the size of his own - that Sun had seen earlier, the very same one he’d used to conceive her with; that thought started to make his shaft swell up again. “No! I mean...I don’t think you should play it with your daddy. You should only do it with somepony you love.”

“But I DO love my daddy!” Flurry whined, somewhat upset Sun would even suggest she didn’t love her dad!

“No, I didn’t mean you didn’t love him, it’s just…” Sun said, his post-orgasm mindset making thinking hard. Sunburst then let out a long sigh, unsure how to explain it. “It’s just...you should never do this with your family, or somepony you don’t love. It’s...it’s something special you should only share with somepony really special to you. Somepony you really love.”

“Well, I love you Sunny...so is that why we did this? Because you...love me?” Flurry asked, unaware of the depth of her question.

Sun simply laid there, hilted to just past the medial ring in the foal, thinking. He’d been with Flurry ever since the day she was born, and since then, he’d been by her side, changing her diapers, protecting her from her own involuntary magical surges and teaching her to control them...slowly getting closer and closer to her in a way that went beyond adoptive daughter and guardian. “I...I don’t know. I love you, but...I don’t know what kind of love it is.” Sun tried to explain, unable to tell his true feelings.

Finally, some minutes after he’d cum, Sun felt his flare and shaft had finally deflated enough to slide from Flurry’s cervix and into her very wet and sticky passage, before he pulled out with a wet, loud pop from the breaking suction and a grunt from Flurry. Sun was wracked with guilt now as he still lay there, feeling like the lowest of low as to have taken advantage of an innocent foal like this. He opened his mouth to apologize again as Flurry stood on wobbly legs and walked towards him in an awkward gait, huge spurts of his nearly ludicrous amount of cum virtually gushing from her abused and reddened foalhood with each bowed step – all unsurprising given just how rough he’d been with the delicate filly – but was interrupted when he felt Flurry’s wet, bright-pink lips pressed to his.

Utterly surprised at Flurry giving him an inexperienced kiss, Sun was simply stark still at the sensation, feeling Flurry’s tongue licking his lip once before she pulled away a moment later. “Mommy and Daddy kiss like this all the time, because they really love each other. I love you too Sunny, a lot.” Flurry said with utmost sincerity, an earnest love that even Sun couldn’t deny was real, “You always help me when my magic gets all weird, you tell me how to make it get not weird, and...and you’re always playing with me and…and I really liked what we just did. It made me feel...special, like you always make me feel...and...” Flurry said, but was cut off as Sun pressed his own lips to hers again, interrupting her.

They shared the kiss for a short while this time, both amateurishly making out as their tongues danced across each other’s lips, licking each other’s teeth and pressing into each other in a firm embrace, until Sun finally broke it as he heard Flurry’s stomach grumble, clearly telling him she was hungry. “Come on, let’s go clean up. We can...we can think about this more later, after dinner.” Sun said, getting a nod from the filly. Glancing from the doorway into the room they just occupied, Sunburst let out a small chuckle as he saw the mess that remained on Flurry’s mattress. A very obvious puddle of fluids were soaked into the cloud that no doubt contained copious amounts of sweat, tears, semen, pee, and foal-juice. It smelled like concentrated sex. The room smelled amazing to the stallion.

As he walked into the hallway of the castle alongside the little filly as they headed towards the nearest bathroom, with him carrying the exhausted and cum-draining filly on his back, Sun saw a family photo of Shining Armor, Cadence, and Flurry Heart hanging on the wall and couldn’t help but sigh. He knew Shining and Cadence would find out eventually, in some way, that he'd fucked their little filly, and could only hope they didn’t vaporize him on the spot. For now though, Sun would live whatever of his life was left, and that started with a bath for Flurry and himself.

Meanwhile, a guard was writing a letter to Shining Armor and Cadence, detailing what he'd just seen happening to the Princess. Before long, it disappeared in a flash of magic, arriving at its destination shortly after.
