Flutterdomme and Twinky Twi

Things had suddenly gotten a whole lot more lively for cute little Twilight. Just having Fluttershy around, constantly teasing and provoking him, was enough to keep him and his monstrous stud-cock constantly on edge... but through Aloe, Lotus and Rarity into the mix and you had a real mess of hormones running through his mind! He just didn't even know where to begin looking.

But he started by staring at Aloe and Lotus. After all... They presented a lot to stare at. Like most of the lesbian mares in this village, both the Spa Ponies were perfectly-stacked breeding stock, equine girls with a pair of stupidly-huge blue and pink breasts a-piece, each girl's rack so big as to rest on their bellies, floppy, neon nipples swinging down past their waists. Their shirts needed to be large enough for ten girls over to hold all that breast-flesh in, but hold it in they did. Maybe not really preserving any modesty in the process - not so long as their meaty hooters strained recklessly at the strained-thin fabric, or as long as their huge, teacup-sized nipples made throbbing erections under the fabric - but it was certainly better than nothing.

Of course, when they started playing with his cock, he just about had a stroke. Fluttershy was distracted with something or other, and Aloe took the opportunity to wrap her fingers around Twilight's pole and give it a few experimental jerks... rather than looking shy or anything she seemed to have much the same attitude as Fluttershy did: callously cruel about using it to her own ends, delighting in making the sissy attached to it squirm and writhe.

"Oh, such a fine specimen!" she said breathlessly in her thick accent, before handing it over to Lotus, who gave it a few pumps as well for well good measure. They rounded the display out by trapping Twilight between four of the meatiest tits he'd ever been in proximity to, jiggling and making kissy-faces at him as they rubbed acres of soft breast-flesh up and down, up and down, making him want to spurt already, and spurt in high quantities. The only thing saving him from this torture was when Fluttershy gave his leash a tug, freeing him from their marshmallow-y hell.

Which, of course, brought the little tyke over to Rarity! Rarity... A real idol among Ponyville, a clear-cut city girl who hardly seemed at home in the sedentary pedestrian life of this backwater village at all. She always seemed eager to move onto the next big thing, hardly sparing a thought for anything other than fashion and business... which made her look extra beautiful reclining.

At the moment, she stretched her flawless ivory body out along one of the many marble couches open to guests, idly thumbing through a popular local periodical about Family Planning. The massively-proportioned mare was deeply engrossed in an article on promoting fertility and ways to ensure your man stallion's seed will take root... Of course, Rarity had never actually dated a single stallion in her life, but it was certainly a fertile ground for her imagination. Perhaps she could arrange a little cock-growth spell for Fluttershy so the girly Pegasus could be trapped into making Rarity's womb balloon with some amount of young... Five or six or seven seemed like it would weigh her down and make her gravid enough to truly satisfy her. She did so often think about how pleasurable being impregnated and being pregnant would feel, after all. And goodness but she had the figure for it: massive heaving tits, childbearing hips so large she only went through specially-modified doorways... Certainly, her personality wasn't the best for raising children, but that's what her dear Fluttershy was for, mm?

Which was why she wiggled her enormous behind as Fluttershy approached, giving the yellow Pegasus something enticing to feast her eyes on... and not having the faintest idea she was giving a certain colt an eyeful to boot in the process. "Lalala... Fluttershy, darling, have you ever thought we could use a few more little children running about Ponyville...?" she murmured idly as she studied a very mesmerizing picture in the magazine of an enormously-pregnant mare.

Of course dear Fluttershy knew Rarity’s obscene, depraved desires to carry a foal within her belly perfectly well! Gosh, it almost seemed absurd for a mare that was as lesbian as it got, who had never even touched or seen a stallion’s cock in her whole life, but Ponyville accepted such things as natural. With being a mare, certain… motherly urges just happened from time to time.

Naturally, Fluttershy knew perfectly well she’d just brought a massive, throbbing cock with enough breeding power to knock up all of Ponyville in one or two cumshots closer and closer to Rarity’s womb, but it didn’t matter. Twilight’s dick was surely restrained by the straining, tight belt wrapped around his cock, and there was no chance anything of this could possibly go wrong! Besides, she knew well how Rarity had looked into spells that might give a mare a stallionhood, at least for a while, but nothing had come of that yet.

She happily, cheerfully clippety-clopped up to Rarity and lovingly leaned into her, giving her a gentle, deep kiss. “H-hiya, Rarity! Would you mind to uhm… maybe close your eyes? I got a little present, you just need to follow along…”

The seamstress grinned widely, and happily closed her eyes. “Gosh, a present? It’s almost our anniversary, isn’t it? You shouldn’t have, darling…!” she cooed softly, while Fluttershy guided her up from her seat. What followed were a few minutes of intimate, loving frenching and snuggling, their massive tits squishing against each other while the two girls made out, and gave poor, twinky Twilight the show of his life. “Now, hold still for a moment. And no peeking, I will be back in just a bit…!”

Rarity obediently kept her eyes shut, hearing nothing but a muffled yelp coming from a voice she didn’t recognize. Sounded like… a little filly? Odd. She was blissfully oblivious to her surroundings, even as Fluttershy guided her through the room, and then to the knees. “Dohoho… Flutters, this isn’t some clever trick to make me go down on you, is it?” Rarity joked, and puckered her plump, curvy lips, which were just made to be wrapped around the towering girth of Twilight’s cock. Speaking of… Rarity still had no idea just what was there right in front of her! Fluttershy gave her a nudge. “Now, keep your eyes closed and reach out for it, see if you can… uhm… guess what it is! I know you always wanted to um…” she went silent.

A moment later Rarity’s dainty fingers wrapped around Twilight’s overpowering, veiny girth, both of her hands unable to fully wrap around the entire thing at once. Her white, pristine hands and the sky-blue of her nail polish provided a stark contrast to the dark purple of the towering mass of dickflesh. “Uhm… Fluttershy, I have no idea what this might be… it’s not your leg, is it?” she said while her hands slowly roamed the surface, squeezing and stroking the virile beast with natural skill without even knowing what it was. She reached the flare, gave it a squeeze. “This almost feels like… Psh… as if…” she snickered, then her hands wandered further down, passed the belt and explored the humongous, swollen jizztanks that churned with endless, stupidly virile gallons of the thickest cum Equestria had ever seen. She hesitated, squeezed and groped them, then hefted one with great trouble. So heavy. “I almost thought those might be your tits, they’re almost as big, but…” She licked her lips. The heady scent of cock was flooding her nostrils, barely suppressed by the flowery aroma of the spa and the steaming hot water. Her hands were once again just below the flare, wrapping around it. Rarity licked her lips.

“Gosh… t-this can’t be… it’s so much bigger than…” she said, pumping it up and down with slow, careful strokes. She was panting slowly, steadily, leaning in closer to the virile beast to take another whiff of its scent.

“It has to be…” Rarity mumbled almost drunkenly, and her eyes finally shot open. “C - COCK…!” she gasped, almost moaned, her pretty pupils turning into pinpricks as she was face-to-flare, inches separating her from a gigantic beast of a cock that towered even above her head. For one moment she was in pure cock-shock mode, gawking at it like a deer struck by headlight, and then her instincts took over. Her womb was burning with a need which she’d never felt this strongly before, and all the way from the heated face, puffy, stiff nipples, the hiked tail and the juices dripping down her thighs, her body signaled nothing but a wanton need to breed.

Drool dripping down her chin, the seamstress got up and jumped his cock with the greed of a starving madmare. Twi had been lying on his back, with Fluttershy on his face, and his massive, musky package on open display. Even with his size, Rarity’s greed made it work. Just barely managing to take the first feet of his cock into her, but greedily pumping her hips to force more, more and MORE of his godly, fat cock into her, even if she broke his pelvis in the process. Or her own cervix.

After all, she was just enjoying her present, right? It wasn’t like she was going to let him breed her or anything!

Fluttershy sitting on Twilight's face was, of course, the reason he hadn't made a single peep or protest the whole time: not much of anything could escape the combined mass of Fluttershy's thighs and ass, especially not a sissy twink's tiny little voice. The sight of it all was almost too obscene to believe...

Almost! After all, Rarity had the proof right in front of her. In this position, all she could really see of Twilight's upper body was his torso: that cute, soft little chest, shaded a lovely lavender to contrast the endless expanse of yellow wrapped all about him. The colt's chest was rising and falling like he'd just run a marathon, despite not moving an inch. It fluttered prettily as he sucked in what Rarity could only assume must be air utterly drenched in Fluttershy's pheromones. What else could explain this hard, hard cock?

Fluttershy had parked her rear entirely on his head, masses and masses of cushion-y, wobbly butt-flesh encasing him entirely, spilling out multiple feet along the marble floor on either side, keeping him from even turning his neck. He'd be stuck permanently nose and tongue-deep in the thick-lipped pussy drenching his face in juices... Rarity couldn't even see his arms, most likely because they were hard at work under her thigh and ass-flesh, struggling - and failing - to keep it all under control.

Poor little mite. Hooked up to a drip-feed of Fluttershy's fertile pussy-smell. Rarity knew the perils of that better than anyone... the brainwashing musk that put you in the pits of pleasure with so much as a single whiff. How many times had she told Fluttershy that they simply couldn't have sex tonight, that her work simply just took total precedence... only to change her tune and become a panting, whipped, collared pony the second Flutters put her nose up between her thighs? Rather too many to count.

And now this boy was getting a double-helping of it? No wonder that black-and-purple monster rod nearly poking the ceiling looked ready to burst! Even the thick, meaty flesh of his horse cock couldn't hide the veins throbbing and bulging beneath the surface, or the way his cum-pipe added the thickness of a whole other cock to the underside. And his nuts! They didn't just reach his knees, they went far past them... Even squatting a little bit would make those beach ball testicles into a comfortable seat for the cutie's dainty bottom. When that machine of a dick got to work, muscles like a dragon's would force that potent fire hose he called his urethra into action, making enough goop to flood every Jacuzzi in this entire spa... if not the whole spa itself!

"Here I go, darling!" moaned Rarity, one hand bracing herself and the other between her legs, fingers spreading her pussy as open as they could, basically pinning her meaty cunt-lips to her thighs. Fluttershy enthusiastically cheered her on as she worked down the shaft, while the Spa Ponies busied themselves with one giant nut each. Normally they'd have supplied a throat each to wrap around each of his seed-pods, but Twilight's ballsack defied such efforts. All the girls were able to do was wrap their middles around the balls and hug them, giving them some paizuri action coupled with plenty of loving licks. Every few seconds Twilight's cock throbbed or the pretty femboy gasped... and the churning contractions in his balls as the oceans of cums they contained shifted were often enough to almost throw the squealing neon-coloured attendants off! But they clung tightly, keeping their grip as best they could, marvelling at the superhuman fertility Twilight possessed.

"He's a monster..."

"How can anyone have such big balls?"

Fluttershy just smirked, rolling her hips on Twilight's face, mewling as he tongued her pussy attentively. That's right, she thought. Everyone else will be just as shocked as you two when they see him~

Rarity and Fluttershy got to work enjoying Twilight together. Rarity planted her hands on his chest at first, moving her hips up and down, but soon she transferred over to holding hands with Fluttershy, the two ponies mashing breasts and mouths together as they both got off using the same boy as their toy. Of course, Fluttershy was the one keeping most of the kissing going... She only had a tongue on her clit so she kept a level head... Meanwhile, Rarity's torso was now approximately 50% penis and 50% organs, giving her rather a lot to handle and consider. In the end she just mechanically worked her hips up and down, spasming, drooling, tongue fucking back at Fluttershy's when she wasn't just drooling idiotically all over her ivory giga-breasts, baby-feeders bursting with eagerness to begin nursing the dozens of brats Twilight was going to pump into her.

And it changed her tune nicely. Where Rarity had previously only toyed with the idea of getting stuffed with foals, now she wholeheartedly embraced it like the most eager of sex-sleeves.

"Uuuuuu~! Pregnant! I'm gonna have foals! My business... Mmmn, my livelihood~! I'll set them aside as long as I need to! I've found something ever so much more important, dahling!!"

The Spa Ponies could only watch as Rarity's enormous ass rushed up and down the length of Twilight's cock, pussy holding him in a vice grip, constantly gushing Rarity's fluids around the pole, the unicorn cumming again and again... until, finally, the callipygian wonder slammed her butt down full-force on Twilight's tiny hips, ripples of wobbling butt-flesh travelling up her hips as she trembled herself silly, finally feeling the onset of Twilight's orgasm and his seed rushing up his cock. She arched her back, howled out through the tangle of her saliva where it mixed with Fluttershy's... and went just about blind with pleasure at the feeling of Twilight's cum jetting up into her womb. Rarity couldn't move, she couldn't do anything, she whited out as pulse after pulse of cum roared up into her, thoroughly churned by the Spa Ponies and now needing somewhere to go!

Twilight wriggled his legs in turn, mewling, thrusting, faintly aware he was impregnating this pony, wanting to impregnate her... marvelling at the fact his first time in Ponyville wasn't just a 5P gangbang on his cock but also mindless, animalistic impregnation sex... It lit a fire under him, making him cum so much Rarity just about popped off from the geyser, her belly swelling and swelling until she tipped over forwards... Twilight knew being a sissy cum-god was the life for him, he knew Fluttershy calling the shots and doing what he'd never had the 'balls' to - creampie everything in sight, that is - was perfect. Rarity had more than capably proven that right here and now~

As Twilight’s monstrous nuts tensed up and he finally released those terrifying amounts of womb-flooding, mare-bloating jizz, Rarity’s eyes rolled back until her pupils were barely visible. She was drooling, panting, cursing, and moaning incoherently, each mighty throb of Twilight’s cock sending her into another, earth-shatteringly intense orgasm. Foam formed at her mouth, dripping down onto her massive, heaving tits as she hyperventilated faster than ever, as if the pretty, prim seamstress was on the verge of having her brain short-circuited by the femboy’s big, dumb and oh so alluring cock.

Just for a moment, Fluttershy wondered if she’d maybe, just maybe taken it a little bit too far… Gosh, just look at the poor girl~! The once so slim, white belly was bloating fuller, swelling up with bucket loads of slimy, virile jizz in hunt of her eggs, while the tears of pleasure and her own spit gushing, streaming down her face ruined what little was left of her make-up at this point. A few moments later, it truly became too much to handle. She sagged forwards, the weight of her bloated, swollen womb dragging her down, and then slowly rolled off Twilight to the side. His hole-gaping cock popped free as Rarity hit the floor like a ragdoll. A blissfully drooling, panting, and utterly pregnant bombshell of a ragdoll. The sissy-cumpump’s filly-breeding geyser of a horsecock once again towered in the middle of the room and dumped massive, rope-like jizzblasts all across the floor, the wall, the ceiling, while three pairs of eyes stared at it with awe, fear, and lust.

After all, Rarity had just been the first. Twilight had much, much more to give than those few pints that had been required to utterly flood the stacked seamstress’ womb. As long as there were three, fertile wombs waiting to be bred, maybe he would just keep going, and going, and going, until the entire spa was drenched in an inch thick layer of his seed, showcasing the sissy’s virility.

Rarity had passed out, Aloe was ready to take her place. Before he’d even blasted more than five ropes of seed through the room, a pair of pink, swaying hips positioned to take his cock reverse-cowgirl style, a pair of azure hands helped her line up, and then she was already greedily, roughly slamming her behind up and down Twilight’s cock, assflesh rippling and bouncing every single time she descended. She didn’t last long. The godcocked sissy was releasing far, far too much for her, having to work against the womb-flooding pressure of his obscene cumshot while riding his dick, but it hardly mattered. She’d taken him halfway at best, but the first, massive rope of seed had already been enough to impregnate her with half a dozen of Twilight’s brats, and as the pressure finally became too much to handle, she yanked herself off with a giddy, dumb grin on her lips, and her very sister was happily taking her place to receive her own wombful of foals.

The plump, drooling lips of her cunt parted, his cum gushed into her, and then she was already getting a full, proper taste of the same fate her sister had experienced. “F-fuck, I never knew dick could feel so go~od!” was all Lotus could pant while she impaled herself upon his cock over, and over, and over. Three pretty girls, all three of them had been dead-set they would never even consider sex with a stallion, and here they were, letting an adorable, crossdressing twink breed them while drooling over his cock. Azure hips swayed, slammed, rippled, until she too drooled and quivered, struggled with the growing heft of her cum-swollen belly, and finally yanked herself free from his cock.

Of course, Twilight hadn't been able to see any of this at all...not with Fluttershy’s ass eclipsing his face the whole time.

That is, until it wasn’t anymore.

Fluttershy released his face, the femcolt’s muzzle drenched with her feminine, motherly pheromones, not too different from how all four, fertile girls reeked of the masculine, studly nutstench that stood in contrast to his lithe, twinky body. He blinked slowly, catching his breath while lifting his head from the bench. Left to him, the bloated, passed-out seamstress. To the other side, the spa sisters, panting and recovering, each one sporting a swollen belly big enough to make them look like nine months pregnant! In front of him… Oh dear.

In front of him towered the stacked, gorgeous pegasus girl with a stern, yet slightly amused glare on her face, pinning him down with her eyes. Twilight let out a girlish eep as she climbed onto the table, but before he could make any attempt at scrambling backwards away from this hungry, domineering succubus, she was already squatting over his legs, and her hand tightly grabbed his still pulsing, cum-pumping breeding pole.

“Oh dear, you’re not gonna run away from me, are you?” she taunted him, her fingers digging into the cumstud’s stiff dick as she jerked it up and down, blasting her tits with spurt after spurt of wasted seed. It was outright comical to see such this beast of a homewrecker attached to such a faggy, squirming sissy, who could probably pass for a mare if it weren’t for that pulsing, thick dong making itself known whenever it was the least convenient! “Huff…! You’d think such a cock should be attached to a stallion, but all you are is a pathetic, big-dicked twink who couldn’t dominate a mare if his life depended on it,” she taunted, “Isn’t that right? But don’t you worry, Fluttermom will make sure that this big, dumb cock will bless Every. Single. Mare. in all of Ponyville with the wombful of foals she truly deserves.”

Throughout all this, Twilight was still gushing his vile, nasty jizz like the cumfaucet he was. All these riding, claiming his dick in rapid succession had pushed him over the edge again and again… He wasn’t sure if he could handle another one, least of all Fluttershy, but his fat, twitching sissy horse cock signaled approval no matter what.

The stacked matron of an amazon grabbed Twilight’s legs, and bent them up towards his chest, almost as if she was planning to peg his bubbly, nerdy ass rather than taking his cock! He mewled. Spine bending, legs aching, and his fat stallionhood was perfectly positioned for Fluttershy to ride, ride, and RIDE him until he’d barely be capable of walking. He felt his flare pulse and twitch against her belly, just above his womb, and she slowly stood up and positioned herself above his cock.

“Isn’t that right, Twinklight? This dick belongs to me,” she taunted him, and finally impaled herself on his cock.

Fluttershy... had taken over Twilight's life. This wasn't like with Princess Celestia, who had pounced on him for lazy shags about the castle whenever she felt bored or listless, this was more like fanaticism. A wild and untamed fervour gripped the pegasus whenever she laid eyes on that proportions-defying breeding rod, the cock that surpassed being merely a "third leg" and was more like a "second existence."

This was like the beginnings of a twisted religious order, one in which Twilight wasn't the ruler, but the support for their object of worship. He was the plinth upon which the Holy Cock rested - or the frame about its painting - and Pope Fluttershy The First seemed intent on calling together a great congregation to worship. He could already tell this was only the beginning... whereas he'd have been content being a quiet, cute little bookhorse cooped up in his library all day, only acknowledging that godlike cock whenever he inevitably tripped over it or flopped onto it, Twilight knew Fluttershy wouldn't be content until she'd gathered hordes of female admirers into the fold of this new order. A communion that began with every pair of panties hitting the floor, and in which the gospel was accepted on one's back with spread legs and open arms.

He didn't need to be convinced she'd pull it off, either. One look in Fluttershy's eyes told him every word of her prophecy wasn't just likely, it was inevitable.

Fluttershy had remained perched atop the mast of Twilight's cock for some time now... Lovely pink tail swishing back and forth with barely-contained excitement. She crouched, posed in an obscene squat that spread her hooves far apart, drooling lower lips just ever so slightly low enough to wrap around the head of Twilight's violently-throbbing cockhead, making obscene squishes and slurps when either of them moved. Her pussy felt so tight and hot and slippery it drove Twilight crazy, making him whimper and buck his hips... but whenever the little cutie got too wild, Fluttershy was always there to lay a few soft fingers on his hyperventilating chest and sweetly pin him right the fuck back down. She usually followed it up with a few sways of her awesome hips, too, that thirsty slit contracting suffocatingly tight every time Fluttershy's heart thumped in her chest.

And with the excitement she'd built up over the last hour or so, it was definitely thumping now. She was as worked up as he was. It was really no wonder Fluttershy had so utterly come around to the idea of being the emissary of a new age of Ponyville sexual hedonism.

"Well?" she asked, keeping her voice as level as her hormones allowed her to. "How does it feel, Spunklight~? Does it just make you soooo horny knowing the entire next generation of Ponyville, every colt and filly in sight, will be mothered by any number of mares from the village, hundreds of them... but every last one of those absolute cuties will all have the same father? We'll have to, mmmph... rename this place Twilight Town."

She bucked her hips, sliding down a few more inches. She shifted her grip to the side of table, allowing her to get a nice up-and-down rhythm going on his cock that got her adjusted to its size. She was the wettest she'd ever been, but this was the biggest his cock had ever been, too. It had just bred through three pussies in one go and was now being offered a fourth. It made Fluttershy's head spin thinking how much bigger he'd really get with a proper pussy-diet instated. A training regime in which the equipment was big tits and fat asses, all on absurdly decadent female bodies. Mmmm~

"You. Twilight fucking Sparkle and his behemoth, ankle-slapping donkey-dick. Even if they don't outright plan to have your foals, they've all still got fertile eggs bouncing around in their wombs! It's inevitable they'll come contact with your sperm. Any mare bathing in the spa for the next month will probably get knocked up from the sheer residue! Mayor Mare will have to declare this place off-limits till they get it all cleaned up... If we tell them, that is~ Maybe Aloe and Lotus will keep their mouths shut for a few months if we ask them nicely, mm? Hee hee hee..."

Fluttershy leaned over Twilight, keeping her body raised in that depraved squatting position, but planting her hands on either side of his head long enough to dive in for a ravishing kiss. It was hard to believe Ponyville's shyest, most introverted girl had become so forward as to thrust her tongue into Twilight's mouth so perversely... But modesty simply wasn't possible with bodies like theirs. When your sexual compatibility with your partner was so perfect it made "100%" just sound like a number... when both your endowments weren't just the biggest of anypony anywhere, but in a constant rush to continue getting bigger, lewder, fuller and outdo each other even more... Suddenly something like thrusting your tongue into a boy-twink's mouth, releasing huge, torrid, lusty moans down his throat while bouncing on his cock, didn't seem so weird at all anymore. "Mmmph... L - looking at you... makes me so horny, Twi-Twi."

She kissed him again, and this time he enthusiastically leaned back into it, releasing another ocean of cum inside of her - soaking Flutter's insides in his essence in the process, making her pussy even hotter, stretchier and more fuckable for his cock and his alone. "You're just... Mmmhh... soooo perfect, just like another cute little animal that needs taking care of."

"Ahhh~ ♥ But you're sweeter than any bunny or birdy... and you've got this obscene thing that won't stop growing... It just keeps getting bigger and bigger inside me... Ahh, I'm seriously drooling..."

She really was. Fluttershy looked down at her slender, sweet pony-toy spellbound, eyes flooded with love hearts, tongue hanging out limply, fingers on her cheek... just completely smitten! It was a look of pure love...

"I need to get it under control, heehee~ Before it seriously causes a problem for meeeee... Mmmm!"

Fluttershy was on the move again, picking up her pace, mounting up on Twilight. His dick bulged so fat her whole insides felt wrapped tight as a drum around him... If this kept up she was seriously going to lose her mind to this dick. So with Twilight on his back, and Fluttershy poised over him in that naughty squat, she took command of the situation in the simplest way possible: she grasped her little beau's ankles, lifted his legs up to either side, and then folded him back onto his chest. The motion exposed his cock nicely, massive ballsack thumping onto the slab as his legs went up, his cock rising up and away from his body... and putting Fluttershy where she needed to be so she could be the one doing the fucking. She started swinging her hips down on him, thrusting her pussy down the pinned pony's immobile cock, keeping him trapped by her lusts. His cock, of course, was still huger than ever, but every slither down the cutie's rod made him that little bit more of her mewling bitch, got him that little bit more under Fluttershy's control. It took its toll on her, too, leaving her constantly shaking, constantly cumming... but she just grit her teeth and fucked through it, looking amazing all the while.

"Mm! There we go... Get nice and comfy under mommy... You're going to be getting - heehee - a lot of this sort of thing in future! Together, we're going to make this town into your personal breeding ground. This dick - that can flood this whole spa, Aloe, Lotus and Rarity, like it's nothing... just a 'few' endless, titanic cumshots... it deserves that much worship~ It should get to fill every womb it wants!"

And then, just as Fluttershy seemed totally possessed by the need to screw herself silly on Twilight's medial-ringed python, a little bit of that shy girl bubbled to the surface: Fluttershy suddenly slapped her hand to her cheek with a cry of exclamation, an "Oh!" that saw her eyes light up with a sudden understanding.

"Oh! But... Oh, how could I forget... I've been so silly, haven't I~? Excuse me, dear..."

"Mmm... I just realized... I can't exactly head that movement up if my words ring hollow, now can I? It would seem weird if everyone was carrying a foal-stuffed womb but Fluttershy herself, right~?"

Fluttershy made up her mind, knowing exactly what she wanted out of this, and moving to get it. "Good thing for cute little Twinklight... Mommy's absolutely stuffed fit to burst with eggs right now... Just waiting for even a single drop of stud-sperm to breed me higher than a kite, mmm~?"

"So now I think I'll take my dick... and knock myself up with it."

And that was it for Fluttershy the maiden. Now only Fluttershy the broodmare remained, her overdeveloped body finally getting to put its fantastic, dream-like, broodmare curves to excellent use. Every movement she took in that heated breeding trance felt intended to drain Twilight to the last drop, milking that cumpump, driving him deeper inside mommy's welcoming embrace, inviting him to be swallowed up in warmth and left drained beyond exhaustion. He was moving under her now, when she wasn't pinning him, as smitten with his love as she was with him, thrusting up into her, moans turning to howls... He'd already bred three wombs and now he wanted number four.

And he got it.

Fluttershy and Twilight only had to move together for a few more minutes before the floodgates broke, swallowing up both of them in the mindlessness of a carnal animal rut. She slammed her hips down on his butt, locking them tightly together. He froze in place, unable to move even a muscle. The massive meaty cock rammed up inside Twilight throbbed... throbbed... throbbed... and then unloaded. The tides of seed kept backed up in Twilight's bloated balls had been going berserk ever since Fluttershy had promised him her eggs, totally overwhelmed by an all-consuming need to procreate with this perfect female specimen, rushing up into his shaft, bloating the already enormous length even further! Fluttershy's ass shook, all her immense curves trembling as she started cumming. She kept her iron grip on Twilight's ankles, but her head shot back and she moaned like a whore, unable to believe how much cum this cute little twink was pumping into her. It just kept going, shooting out hot gushes beyond number, more than the other three mares had got put together. Fluttershy's voice came and went, sometimes she howled, other times she just choked, clinging to Twilight for dear life as Twilight put enough cum in her to repopulate Ponyville a hundred thousand times over.

Goosh~ Sploosh! Fluttershy's already-enormous middle grew more and more, not just dropping her cum-bloated belly directly onto Twilight but also putting her breasts up and weighing down on her thighs. She kept on growing, unable to believe how big she was getting, and knowing somehow she wasn't even half-done being flooded. She started cumming all over again, babbling incoherently about the glory of this member... and Twilight's balls just seemed to be getting bigger. Those humongous nuts had produced enough cum to fill a couple of jacuzzis and they'd gotten bigger.

Twilight kept cumming, his orgasm passing its first minute of brain-melting, dick-pleasing pleasure. He was the one ahegaoing like a sissy bimbo this time, the pleasure of a cumpump writ large on his face. All he could feel was his cock and those massive balls forcing jizz up through it, and they felt amazing.

Bloop. After what felt like forever, both ponies felt their superhuman sexual antics coming to a final close... the moment where their senses returned to them and they actually began to be able to process thoughts again. They both heard the geyser being pumped into Fluttershy start to subside, the churning froth settling down to a few popping bubbles. It almost went without saying that Fluttershy's belly had buried Twilight, her womb containing almost the entirety of his orgasm and now spilling off the table on either side... nearly touching the floor. Her breasts, too, had doubled in size... which meant in her current arched position her nipples nearly brushed the ceiling. That might prove inconvenient later, but in her current state she genuinely didn't care if they didn't subside back to their original sizes... After all, she was a broodmare, and she seriously doubted Twilight had been so 'thoughtful' as to put just one foal in her. A body like hers had room for dozens and his mind had probably been spinning with exactly the thought of giving her those dozens. Hers certainly had when she felt that cream pumping into her.

Fluttershy rubbed her belly, able to feel her super-engorged womb trembling and quaking with sperm just below the surface now. Just sinking her finger into her flesh even an inch let her stimulate her bloated womb directly, almost getting her cumming all over again. And this part probably was permanent. Once she was fully pregnant and ready to pop, she might be even bigger than she was now. She might feel like even more of a sexy, maternal goddess.

"Mmmhh... My cock. Mine. Fluttershy's."

Twilight blushed as she freed him from beneath her tummy. She gave him another kiss, one he warmly returned. "Y - Yours."

She snuggled him, pulling him onto the trifecta of her breasts and belly, wrapping both arms around him and giving the colt a squeeze. "Mine!"
