Shortly after his arrival in Ponyville, a hyper-endowed Twilight Sparkle finds his peaceful country life disrupted by a needy, pervy Fluttershy

Previously, the prodigiously-endowed Fluttershy would have been right to assume she was Ponyville's girliest, most submissive resident. But the arrival of Twilight Sparkle, with his wide womanly hips and soft-spoken ways, has thrown her whole world into chaos. Now, faced with a stallion even sissier than her good self, Fluttershy decides he needs some cock management. For the first time ever, she decides to take charge.

---

The goal with this story was to write something where a hyper-endowed, hypersexual male character (the type who'd normally have a massive harem and be an ultra-dom) instead has all that handed to him by a hardworking play partner. Fluttershy is his dominant, but she's still in awe of his incredible cock and fertility, and she can't help but deliver him other girls to play around with as the story unfolds.

Fluttershy Trains Her Pet

Another peaceful day in Ponyville. As much as Twilight Sparkle had adored Canterlot's large libraries and the company of their nation's wise rulers, Celestia and Luna, he had to admit quiet country life had plenty of its own charms as well. The calm, the quiet, the sweet and friendly ponies... he adored it all.

Best of all, however, was the extra room country life afforded to ponies of hyper-endowed proportions. Back in the castle, even transporting his ginormous member from one room to another had always been an ordeal: "big dick problems" generally extended to not being able to fit inside a girl more than they did accidentally knocking a wall down or tripping someone up. And he could forget about ever ejaculating inside a mare... unless he wanted her swollen, cumflated middle to demolish a city block or two. Out here, he didn't have to worry about any of that!

He could even make his trip over to Fluttershy's by walking through the town's streets if he wanted, assuming there weren't too many people about. Normally he'd have teleported, but he decided a nice stroll would be lovely today. So, with a magic charm to lift all those feet of flaccid, wobbling cock against his smooth, soft chest where he could keep it from swinging around too much, he headed out the door.

A few minutes later, the tiny colt was knocking on Fluttershy's door, wondering just what she'd called him over for today.

Fluttershy's cozy cottage had been specifically adjusted just to make room for the extraordinary amount of wobbling, heaving titflesh the shy, lovely mare possessed. With most of her body mass located within her bouncing, swaying and wonderfully soft bosom, her doors were a good bit wider just to make leaving and entering less of a hassle for her!

When Twilight knocked, he soon heard the creaking and clattering of furniture as those wonderfully soft curves began the precarious process of transporting themselves across the room to reach the door, and open it. Fluttershy stood before him, in all her abundance, with only a few askew paintings and wobbling vases remaining behind to identify her passage.

The sight of a tall, hyper-stacked - with a bright, happy smile on her mouth - beamed down on the innocent, boyish colt! And she was as sweet as she was gorgeous! Ever since Twilight had come to Ponyville, the two had become fast friends... actually, Twilight had been here just yesterday to share tea with her. Therefore, there was no reason to be nervous around her.

... And yet, Twilight still felt a tingling sensation in his gut, as if the pretty, cow-titted mare had... something planned, whatever it was.

"G-Good morning, Twilight!" she said softly. Before he could even respond, she leaned down to give him a very, very close hug, her massive bust squishing into him. It didn't stop there either. Fluttershy, arms wrapped around him, simply lifted the studly colt high into the air and pressed her lips against his. He felt her tongue for a moment or two. Just a short, friendly, utterly platonic kiss that lasted... a few seconds longer than it should, before she finally set him down, a bridge of spit connecting his mouth to her soft, pillowy lips. "I'm so glad you're here! Is there anything you'd like Mommy Fluttershy to do for you? Just sit down~ You must be... very tense and exhausted as the only stallion in such a big village of mares!"

She was right about that. An exclusively female community like Ponyville opening its doors to a single, solitary stallion... you bet Twilight was tense! Although... exhausted? He wasn't quite sure what Fluttershy meant by that part just yet. Was the pinkette bombshell with the ridiculously abundant curves hinting he might be put through his paces soon? He couldn't imagine what the 100-odd fillies and mares could possibly come up with to leave him tired, panting and worn out.

Well... He supposed a few of them had shared totally platonic Ponyville kisses with him, like the one Fluttershy was giving him now. He only gave the briefest squeak of protest before he melted in the warmth of his caretaker's embrace, immediately feeling so good and relaxed he wondered why he would ever have had a problem with it in the first place. Who wouldn't want to be wrapped up in Fluttershy's arms, clinging to her with his body sandwiched between her melons, his open mouth mashed against hers while their tongues busily worked together in the middle?

When Fluttershy set Twilight down, he still looked rather dazed and overwhelmed. The big-hipped bimboi slumped backwards, drooling from the spellbinding kiss, partially aware his monstrous member had stiffened up enough to snake along and over the floorboards somewhat. The bright-eyed cutie had come dressed somewhat formally in a dress shirt, bowtie, and a magically-enhanced pair of booty shorts that must be made of the most magical material known to panties for their seemingly-infinite capacity to stretch and bulge to keep him wrapped up no matter how hard he got. The effect ended up looking rather like a condom fitted to his veiny, throbbing member.

"Mmh... Mm... Well... Of course I'll sit~ Tea, please! And... Maybe a massage! My shoulders are a little stiff..."

Who knew just what the dominant, towering bombshell of a Sun Goddess had planned, sending Twilight off to the cozy little town consisting entirely of mares, each prettier, bustier and more fertile than the one before?

Well... Surely her plans were nothing short of platonic!

After all, even though Celestia wore nothing but the most cockteasing, deep-cut outfits whenever she was around the monstercocked colt, her love for him was gentle and maternal, a mare who loved all of her ponies equally! To think all of this was anything but pure coincidence was almost treason, really.

With Twilight still standing dumb-struck in the doorway, Fluttershy just let out a little, amused giggle, and decided to just take him to his seat! With how small and cute he was, there was no way she could possibly resist the temptation of picking him up and carrying him like a child, even if it meant that she'd have his massive, fabric-bulging fuckpole grinding against her wobbling titties! Especially if it meant that. If he was any more socially aware, he probably would've noticed how Fluttershy 'accidentally' placed a hand at the base of his shaft, remarking "Oh yes, you seem awfully... stiff."

Twilight let out a cute little "Oof!" as Fluttershy plopped him in a mare-sized armchair... meaning it was far, far larger than he was used to it. Even with his considerably fat, bubbly butt he still only filled about a third or so of the seat.

"Just wait right here, little man, I'll be right back with some refreshments!"

And with that comment, Fluttershy turned and bustled - deftly at that - out of the room, to go prepare some refreshments for them.

And Twilight found he was left with a very, very big problem. This was usually the part of his stay where he'd take a leisurely glance around Fluttershy's home, admiring the furnishings, but... well! That impromptu snuggling session in her arms had left him positively priapic, his member fucking deep into those shorts like they’d bought it dinner! He blushed hotly as he stared it, remarking to himself how well it obscured the rest of the room from his vision!

Most stallions, despite being hulking, hung, mega-stud stallions didn't have as much member to deal with as petite Twilight did. Not just as thick around as a milk bucket, it could also get long enough on a good day to poke up past his face... even further if he was having a really intense session with his favourite erotica. Now he stared at it in blatant cock-shock, never getting used to the size no matter how many times he saw it. He wrapped his hands around the bulge, trying to point it downwards so it wouldn't be thrusting lewdly straight at Floots when she came back. In the end, he simply folded his hands on his lap, trying to press it down, and act natural.

It was tough having manners as good as Twilight's. Most stallions, after all, in his situation would have just ripped their clothes off the second they got stiff and gone to town on a big, horny, lewd-bodied mare like Fluttershy... but he had built his reputation on being a scholar with dignity and poise! He didn't want to abandon that no matter how hard and throbbing his monstrously huge twink-cock got!

Speaking of which, Fluttershy still wasn't back, giving him some time to work on his appearance. Being dropped down so suddenly also left Fluttershy responsible for the colt's mane tumbling down over his eyes, so with the cock situation mostly resolved he was soon fussing and fawning with his incredible hairstyle. He showed almost as much vanity as their friend Rarity!

Finally settled, Twilight sighed happily, easing back into his seat. He pushed his thick-rimmed glasses back up his nose, tossed his butt-length hair back, and waited for Fluttershy.

Meanwhile, Fluttershy was still hard at work in the kitchen. She distracted Twilight from his private little grooming session with cheery conversation, keeping the talking going all the while as she busied about in the kitchen. He replied back with a sunny smile, chatting about this and that, just delighting in the sound of Fluttershy's voice, not thinking about much beyond how much fun he was having spending time with her.

Just the way she wanted it.

As it turned out, Fluttershy had a very good reason for wanting to distract Twilight... And this was because the tea she was about to ease down the thirsty little stallion’s gullet wasn’t just any regular tea.

No, the stacked mare had added just a tiny little bit of a virility-enhancing herb to the mix, one to positively ensure Twilight's nuts would be overflowing with thick, slimy and mare-breeding nut sludge given a few minutes.

It wasn’t a careful or sensible decision, but Fluttershy was far too shy and naive to know that. After all, how could she possibly know the risks involved with feeding such drugs to an already stupidly-virile, gigacocked colt? Short of a lengthy stay in Canterlot Library and an exhaustive record of Twilight’s physical condition, there was no possible way Fluttershy could ever have known this sort of masculinity-enhancing herb could backfire when used on someone like Twilight, resulting in such an over-production of hormones and sticky, lewd sex fluids that someone like Twilight would be left feeling intense, throbbing in his massive, swollen blue balls...

Until he was drained. A lot.

Well. Either she hadn’t obtained those records... or this was exactly what she was planning to have happen. Who knew?

A minute later, Fluttershy returned. She handed Twilight his tea, watching him studiously as she did so.

She cooed. "I added a little milk... I hope you like it," she said softly, and pecked his cheek. Rather than taking her place behind him to massage his shoulders, though, Fluttershy gave him a moment to start drinking, and then knelt down right in front of him with an almost greedy little grin on her muzzle! She stared at the way his massive cock bulged his pants, and put up the disapproving, dismissive look of a mother. "Really, Twilight?" she huffed softly, "Can't you keep that big, stupid, smelly dick of yours in check for a few minutes? I-It's not nice to get a stiffy while hugging mares, you know?" He was barely hard yet, and Fluttershy's nipples were visibly stiffening through the fabric of her sweater. She was one to talk.

"A - Ah? I'll... I'll have you know it's purely a perfectly-ordinary biological reaction to the opposite sex!" huffed the embarrassed nerd, looking around his shaft to see her. He rested his elbows on it as he sipped his tea.

"Oh... This is divine~" cooed the little colt, his hooves kicking. "So sweeeet!"

Then he saw Fluttershy kneeling before him, and dragged his eyes back to her body. Her amazing, plump, perfectly-proportioned body, holding up and supporting that hyper-sized rack. "G-Guhh... Umm... As I was saying, it's perfectly natural and healthy... Ponies go into heat all the time, I'm no different!"

Of course, while it might be a clinical issue to discuss in other settings, openly discussing his arousal with Fluttershy suddenly seemed very perverse. Twilight blushed, burying his face in his tea and taking a few more frantic sips to calm his nerves. And that herb Fluttershy had spent the morning mashing up, the herb so cleverly disguised in the little brainiac's tea, began to pour into his body, making its way through his system, rushing down to the spot between his legs and beginning to put his balls in an iron grip... Twilight wouldn't feel it just yet, but Fluttershy could already see the telltale signs it was working: his breath coming faster, his pupils dilating, his nuts sloshing and churning and quaking... In a few minutes, Twilight was going to be making enough sperm to impregnate all of Equestria, let alone one little Fluttershy.

No matter how often he saw her perfect, curvy form, he'd probably never get used just how tall she was... Not as tall as Princess Celestia, but even while kneeling Fluttershy was still towering over the boyish colt! She had that hungry smile on her motherly, pretty face while she eyed him up, licking her lips while waiting for the brew to take effect. She didn't have to wait very long, but... as she waited, it became more and more clear that he might not be the first one to lose control.

Fluttershy's gaze drifted from his face lower, and lower, until her stare was blatantly locked to his big, fat cock. H - huff. Such a cute nerd, with a cock fatter than... way, WAY fatter than anything the two or three next biggest stallions in all of Equestria were packing together. Fluttershy's tongue slid over her soft, squishy lips. "Nf... D - don't be silly, Twilight," she said, "Ponies don't just... 'go into heat' all the time!" She huffed a little, cheeks flushing with growing lust. "I - it's not like all it would take for you to go into h - heat.. I mean, into rut is a small little hug!" Fluttershy licked her lips again, her mouth stayed open as she gawked.

Just a few moments or minutes had passed since she'd taken her place in front of him, and the stacked pegasus was already leaning far, far forward, her pretty mouth wide open, and now just one or two inches away from his big, dumb, fat, mouthwatering cock! He could feel the warmth of Shy's breath washing over it. Almost as if the mere presence of his massive, fat dick was enough to make the fat-titted, motherly pegasus go into heat.

"But I guess if you really can't keep it down around Mommy Fluttershy..." she said, licking her lips, "Then I'll just have to make it go down, isn't that right? No, I HAVE to make sure this won't happen again! What would Princess Celestia think if you popped such a big, fat stiffy around her, Twilight?" she cooed. Wait, was she... Oh yes, she was. She had grabbed the lower rim of her sweater and pulled it over her head, laying bare her massive, perfect cow-tits, which were now just barely hidden by a lacy bra which struggled to even contain her nipples. Mountains of boycock swallowing titflesh, each breast so big a curled up Twilight could comfortably fit into it!

One moment later, and Fluttershy's immense, wobbling tits were grinding right against the overpowering, pulsing bulge of his musky breeding pole! No matter how big he has at this point, as long as he wasn't fully hard, Flutter's gigantic rack was still enough to fully take that twitching bulge into her cleavage! Spit was dripping down Fluttershy's chin, tiny little hearts had showed up in her pupils, and he could only watch those nostrils flare up again and again as she took in the scent of his musk. "Nff... Now, be a good colt, and whip out your big, fat cock." she whispered hotly, "There's no way I can let you walk home with this thing, it just wouldn't be decent... And I guess I'll just have to drain you now, until you've learned your lesson!"

Twilight was already losing his mind even before the drug kicked in! A teasing, overbearing Fluttershy threatening in a low, sultry voice to use her big tits on him to make him cum? That was like pure arousal injected directly into his dick. He couldn't think of something hotter if he tried, and, given the size of Twilight's brain, that was saying something.

"Guh... Guh... Mmmm!" He squeaked as Fluttershy took her tits, by far the biggest of any filly in Ponyville, and engulfed the armchair he was sitting on! Breast flesh sank into the cushion on either side of him, weighed down on both the arms until they started to creak and groan like they might break... and went halfway up the back support! Her tits weren't just big enough to smother Twilight, she'd smother the entire armchair he sat in, too!

He'd had an impression of how good this would feel during their hug - feeling Fluttershy's sweater-puppies mashed against his shaft and all - but now that thick, coarse garment was gone and the filly pressed her big yellow tits directly against him, he was in heaven. He started thrusting, mouth open, eyes hooded, little purple chest fluttering under his dress shirt. It was all too much for cute little Twilight... Even the most chaste of colts would have tossed aside their clothes immediately for a taste of her, let alone a pervert like Twilight who'd been drooling over Fluttershy for some time. He obeyed Mommy Fluttershy, and he obeyed her very fast.

"Y - Yes Fluttershy!" he squeaked, looking up into those adoring, heart-studded eyes... figuring his own were probably doing the same at the moment, his pouty lips pursed in a sweet "Ooh~" of joyful submission.

He wriggled and squirmed in his seat, trying to figure out how to shed the stretchy shorts wrapped around him like a condom... and mostly just ended up working and grinding himself against the supreme softness of Mommy's chest. "Ghh... Mmm!"

The tip of his shorts began to balloon... not from Twilight's orgasm but from sheer precum alone, gallons of the stuff gushing into and inflating the garment. Fluttershy felt it growing between her breasts of course, all those magical spells trying to keep Twilight's clothes together... but there was really a limit to how much arousal they could handle. As Twilight curled his toes and mewled sweet praise for mommy in mindless joy, his cock throbbed up another whole foot in length and the shorts finally gave up the ghost. What started as a network of crisscrossing tears revealing the purple and black flesh underneath suddenly all came together at once, shredding the durable garment clean off of him and dumping all that delicious cum he'd made directly on her tits.

Free of the restriction, able to feel her directly now, Twilight redoubled his efforts, sinking his fat cock into Fluttershy's melons directly, working his big hips to fuck the hell out of that bottomless chasm of breasts.

No matter how much taller, stronger, and bigger Fluttershy was, with tits massive enough to easily pin him down, it would have to be seen if she could keep the monstercocked stud of a colt down at this point! Especially with his already massive, near-bottomless jizztanks, each of which packed more than enough jizz to keep pumping, pumping and PUMPING out endless spurts of slimy breeding spunk for hours, if not days upon days, as long as he was given enough fat-titted, horny breeding fillies who wanted nothing more than his ungodly virile monster of a cock.

And that was how virile he'd been without any sort of additional 'help'. Without any herbs, without a dash of Fluttershy's very own milk in his tea, and without her massive, bouncing tits in front of his face! If the cow-titted pegasus had ANY idea of just how fucking virile Twilight was at this given moment, the shock alone would probably be enough to send her into a coma. Luckily, she didn't, and even if she did, all she had eyes for was his big, fat fucking breeding pole poking out from between her cleavage!

The thought that a single stallion could even be HUNG enough that his cock didn't instantly and completely get swallowing in the marshmallow-hell of Fluttershy's motherly, cockteasing cowtits was nothing short of staggering for the plump-lipped, naive and cock-addled pegasus broodmommy! "A-ah~! S-such a good boy... S-so fucking HUNG..." she panted, drooled, and greedily attempted to wrap her lips around his daunting flare, only for a single, powerful twitch of his cock to completely overflow her mouth with his thick, virile prejizz, a single drip containing more sperm than any other stallion's full orgasm. It was far too much for the cowtitted mare to handle, spurting, dripping from the corners of Fluttershy's mouth as her pupils turned into shocked pinpricks, and she pulled back to swallow.

"Hffr... S - so much..." she panted, her voice swaying between praise and utter shock, even worry. "G - good boy! M - Mommy will turn you into a true, proper stud..." she panted softly. And that was when the herbs she'd mixed into his tea really began to kick in. Poor Twilight's gigantic, monstrously oversized seed pods, each one as fat as a watermelon or bigger, began to tense up and hurt. Those overly productive, churning cum-factories were suddenly kicking into overdrive, giving him the worst blue balls he'd ever had in his whole life, each massive cumtank seeming to grow a good two inches thicker in girth.

It was starting to seem doubtful that other stallions even needed to exist anymore. All those barrel-chested hunks Fluttershy had spent so much time drooling over completely and utterly paled in comparison to what this dorky, goofy, long-haired, wide-hipped sissy was packing between his legs. It was like some cruel joke... as if he had enough masculinity in him for a thousand other stallions, but it had all ended up jammed into that mare-taming cock.

This was the first cock ever that wasn't instantly overwhelmed by Fluttershy's boobs. This was a majestic, masterful god-cock that made even her obscene rack quake with each gush of cum up the shaft, each splatter of his hot fucking goo all over the ceiling.

And he was getting bigger, too... Her herbs had really done a number on Twilight, his already-excessively magical Unicorn body taking the incredible energies rushing into him and knowing exactly what to do with them. His dick, already poking from between her tits to bare the musky, black, flared tip to her shocked eyes, bloated even more masculine, more powerful, forcing the tight compression chamber that was her cleavage open, spreading her tits to make more room for dick. Twilight's nuts, already enormous, expanded with a gushing sound like a raging river, bloated seed pods swelling more by the second, overflowing his own lap and stretching out across the armchair seat. He yowled and howled, clenching his ass as he struggled with that heady mixture of pain and pleasure, feeling trillions and trillions of new sperm rushing into his sack, bloating it, inflating it, swelling what had once been a deliciously fat little nutsack into something more like a beanbag. Twilight's nuts filled his lap now, still trapped under Fluttershy's equally oversized bust. Each of their bodies was so ridiculously hypersexual as to be unbelievable... You could search all of Equestria and possibly never find a more indecently-developed pair~

He needed to cum. So he did, of course.

Twilight arched his back, eyes bulging, tongue stretched out, his hands clutching Fluttershy's tits in a deathgrip as he felt something like trying to force a dozen bowling balls worth of sperm up his cock all at once and not coping with it one bit... and then the pumps started. Glorious gushes, each releasing volcanic blasts of semen from Twilight's enormous balls, taking those sloshing contents and liberally dousing the room, and Fluttershy with it.

On a good day, most stallions could manage around 7 hard pumps that shot maybe six inches or so... Twilight wasn't limited to such limp-dicked numbers by any measure. He continued to moan and buck his hips as he splattered the ceiling and Fluttershy's tits over and over, dumping the contents of his bloated ballsack on her face and in her hair. It took a full 40 pumps before that titanic shaft stopped twitching, before Twilight was finally done cumming.

She’d really done a number on poor little Twilight. Really, who ever could have guessed that the full-figured, softly-formed pegasus had even a single dominant bone in her whole body? Who could have guessed she had the strength to not just reach out and take a male for herself, but also enter into a clean, clear mistress/slave relationship with one! Somehow, in a single day she'd gone from Twilight's friendly neighbour to his dominatrix and his owner, having that slutty little boytoy eating out of her hand like he'd wanted this all along.

Still... Whether it reflected on her as a surprise domme, or him as the sissiest, girliest, twinkiest little piece of ass in all of Equestria was up for debate! Maybe he was the one to blame for being such a sweet little sub that even other subs wanted to dominate him. That seemed the most likely explanation~

From there, the pair’s play only progressed. Costume play seemed like the obvious next step, with Fluttershy having a simply darling outfit she wanted him to appear in.

Twilight Sparkle was surprised at how much enthusiasm he had for the idea. But crossdressing in gorgeous girl’s clothes really made so much sense when one really looked at it objectively. His big fat ass, thick thighs and wide hips cried out for that sort of treatment, and Fluttershy knew this better than anyone. Soon, he would as well.

The next time Twilight was over, Fluttershy was quick to thrust a package into his hands and hustle him upstairs, both ponies all-too-eager to get the fun underway. Twilight hurried to change, taking the stairs two at a time, and quickly sequestered himself in the bedroom before laying the clothes out on the bed to examine them. And of course he fought with one of the hardest, most raging boners of his adorable little life as he did so.

A pretty black-and-pink skirt. Black stockings that looked much too tight for his fat thighs, panties to pinch his huge fat butt, a little top and a tight, tight collar... He squealed in delight to look at them all, practically cumming right there on the spot. He’d never dressed so quickly, or with so much care. Every rustle of silk around him seemed magnified a thousand times, whether it was the sound or the feel of it sliding along his meaty, womanly curves.

And when Twilight was dressed... ooh! The sensation of all those silky, girly clothes wrapped around him...! It was too much! The cute little pony popped a colossal, throbbing erection fit to flood Ponyville with cum.

And that was how Flutters found him: kneeling on the bedroom floor, hyperventilating, multiple feet of cock pointing straight up in the air, bursting out of that flimsy pair of silk lingerie panties, engorged and masculine and leaking buckets of cum from the tip... all while a confused Twilight stared at it in awe, fluttering his hands up and down the shaft as if not sure whether to jack it off or try to pat it back down.

"H - Help!" he whined in that sweet little falsetto.

As the absurdly stacked pegasus-domme 'caught' him, all she could do was frown. "Really, Twi? I just drained you twice this morning, you can't possible be..." Fluttershy let out a huff as his masculine beast of a cock merely responded with a greedy throb, cum continuing to gush from his flare. She flicked her dainty fingers against his massive cockhead, his jizz instantly clinging to her fingers. Shy didn't seem to mind, diligently licking them clean, before finally getting to her knees right in front of him, his monstrous cock throbbing right in front of her muzzle.

"Huff... Such a big, fat, smelly, insatiable dick..." she mumbled, and threw him a glare. "You should be ashamed of yourself, Twi! Constantly getting hard, flaunting your stupid, fat cock and swaying it in front of my face to make me suck you off... I shouldn't have expected anything else from a colt! I'm very happy with my girlfriend, you know, and your big, dumb dick won't change that!" Fluttershy berated him, but of course, the fat-dicked twink had done no such thing! If anything Fluttershy was the one who constantly, subconsciously or not, swayed her fertile thighs and hips in front of his face, pulled him into titsmothering hugs, or whose hands constantly roamed his groin whenever she had the chance.

Fluttershy's hands were at his swollen nutsack, hefting each monstrous, overflowing ball individually. Just... how was this even possible? He felt even more full than last time... The pegasus let out yet another, annoyed huff. "But oh well, I warned you!" she cooed, a smirk growing, as she pulled something like a belt or collar from her wobbling cleavage. "And I just can't have my Twisissy stumbling around Ponyville like this, so I guess I'll have to take you with me on my spa trip with Rarity where I can keep a close eye on you! But first..." Her grin was almost voracious by now, malicious and greedy. The belt was wrapped around the base of his monstrous cock, and then tightened and tightened, until even the flow of slimy jizz from his cock reduced to a trickle. "Much, much better, isn't it?" she taunted him. "I guess your dick won't be an issue for today, if you play nice I might take it off in the evening~!"

A leash, once intended for the collar around his neck, was attached to his cockring, and Fluttershy rose to her hooves. She tugged at the leash, making her big-dicked boytoy’s cock twitch painfully, while his blue-balled, denied nuts churned in protest. "Now get up. I have to get going, and you're coming with me... Hope you enjoy the mares staring at your big, dumb dick! If you just can't keep it down, then everyone staring and laughing is just the punishment you deserve, isn't that right?" Fluttershy hummed, and was on her way. A minute later, they'd left her home, and were on their way through Ponyville, still dragging her fat-dicked boytoy along with a leash painfully constricted around his cock.

And that was how Fluttershy and Twilight had their first "date." A date in which little Twilight was dressed in a truly humiliating, embarrassing outfit and paraded up and down the streets of Ponyville for all the mares and fillies to gawk at to their heart's content... where each step of his silky hooves down the path required a monumental effort and force of will.

His head felt so foggy, so messed up, as he struggled to concentrate on even something as simple as walking. Now, a brainiac Twilight might be under ordinary circumstances, but this preppy schoolgirl-style outfit made too much of a tasty morsel out of him. It appealed far, far too much to his naughty fantasies of his enormous-cocked, yet otherwise svelte, body becoming a plaything for much larger, more powerful mares. Combined with the stares of all the busty beauties flanking him and Fluttershy on either side of the street and he had the fattest, thickest, hardest erection of his life.

That battering-ram of a horse-dick spoke all too eagerly about how much Twilight enjoyed all this, proudly rising up out of his thong - the flimsy garment reduced to little more than a few straps straining across the length of his huge, dark nutsack - to jab ominously directly up into the sunlight, practically passing the top of his head. Every few steps it throbbed violently, like a volcanic eruption was about to burst forth, but Fluttershy always took care of that with a rather twisted tug on the leash that pulled him dick-first along behind her. A few times he stumbled enough that he fell forwards... but every time this just ended up with him buried face-first in her ass, and his dick either trapped between her thighs or under her armpits. Fluttershy really had a good handle on this little minx now.

A few of Ponyville's finer girls stopped and gawked, of course, chattering away just out of earshot. Phrases like "Ugh, she's lucky," or "I want to tie him up, too..." or "I wonder if she'd sell me a few pints..." reached his ears, further adding to his shame, his embarrassment, and most of all his need to get that big cock ejaculating thick and full.

It was 'just' a lovely little village full of lesbians, and yet every single of these pretty, fat-titted mares looked like straight out of one of Twilight's many, perverted daydreams! It was quite staggering for the twinky unicorn to see so many gorgeous amazon-bimbos gathered in one place, even the smaller ones towering a good feet above him. So far he hadn't seen a single girl with tits smaller than her own head...

Their stares followed him, glued to his monstercock. Some gawked, some drooled, a few grinned with voracious, hungry looks that promised pelvis-shattering breeding sessions, and a few bouncy lesbians stared at his painfully hard breeding pole with dumbfounded looks suggesting that this truly was the first time they ever saw a cock. They reached the Ponyville Spa, the doors closed behind them.

Fluttershy made her way to the empty counter and rung a bell, dragging her big-dicked boytoy along by his cockleash. "Just one second~!" a voice called out, and a few moments later the two gorgeous spa sisters, Aloe and Lotus, stepped into the room. They were coming from the spa area, and it showed. Each sister wore nothing more than soaked, almost translucent t-shirt pulled over her massive, wet tits, and a matching thong. "Ohh, good morning, Miss Fluttershy! Miss Rarity is already waiting for you..." Her gaze fell upon Twilight, and she couldn't help but bite her lip. Oh dear. Both bodacious, busty bimbos did their best to remain professional.

"Ah... Miss Fluttershy, I hate to have to say this, but... This is a 'Girls Only' Spa...!" She pointed at a sign above the spa area, which stated "Topless Area --- Mares only!". "I-I am sorry, but we can't allow your little friend to come in," she added quickly. But Twilight's busty mistress merely let out a friendly, bright giggle. "Oh, don't you worry... I have him perfectly under control, see?" She pulled him up front against her cleavage, his massive cock bobbing between the two girls. They stepped around the counter to take a closer look at what Fluttershy was showing them. "Ohhh... A belt and a leash? That's very clever, Miss Fluttershy..." the two girls marveled, their hands roaming his beast of a cock in a perfectly symmetric pattern.

The pegasus smiled. "As long as he's wearing it, there's no way for him to threaten any mare with his slimy, pungent stallion cum," she cooed happily, "We wouldn't want anyone to get pregnant, after all," she said.

The girls nodded.

Of course not. Flutters giggled "Besides... He's barely a stallion! If it weren't for that dumb, smelly cock, he'd be so much of a sissy you'd mistake him for a girl! Isn't that right, Twilight?" she taunted, "You won't cause any trouble with your big, fat cock, right~?"

Once all of that was settled, the both were finally passing through the curtain which separated the entrance from the spa area, and approached Rarity!

Fluttershy Mates Her Pet

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!"
