> The Morning
> --------------------------------------------------------------------------

        Equestria’s most famous DJ slowly began to sit up in her bed, the motion accompanied by a loud groan from the DJ’s own mouth. Vinyl Scratch didn’t like waking up on the best of days, and yet something about today felt more difficult than all the others that had preceded it. As if there was some great force, or a literal weight that was holding her down onto the bed. Finally in an upright position, the pony gave a snort, shaking her head. Everything was odd about this morning, everything felt off to Vinyl. The memories of last night were a blur, and even now her mind was in a haze. Questions darted in and out of her mental scape. Why did she feel so heavy? What was this...slimey, grimey sensation? Most of all, what was that smell!? 
        The large mare just huffed, swinging her legs out to the side of the bed, before beginning to move into a standing position. Vinyl’s hooves echo’d loudly through the room when they met the carpet, that also confusing Vinyl, but she just shrugged and made the effort of getting up on two legs. Even this took some effort on her part, and when she was finally standing, the mare just huffed. Now on two hooves, Vinyl began to stretch herself out with a loud groan, feeling the weight of lifting her arms. Vinyl smelled an odor began to gain strength as her arm raised, before she looked at her pits. What was staring back at her were large tufts of dark blue, matted with sweat. The large mare blinked a few times, the oddness of it trying to register in her head, before she just shrugged and let her arms drop to her side.
        Vinyl’s arms collided with her sides much sooner than she expected, letting out a wet slapping sound to echo throughout the room. She stood there, silent for a few seconds, a frown on her face. What in the world was off about this morning? She couldn’t place it, but the mare knew that something was different than all the other mornings! Vinyl began to think of it more in depth, reaching up to tap her chin, unable to notice as both her chin and it’s accompanying twin jiggled and wobbled with each and every pat, her face scrunching up in thought, before a suddenly booming noise broke her concentration. It was her stomach, growling out.
        Two hands went down and rested on her stomach as if to sooth it, Vinyl looking down for the first time. What stared back at her was not only two breasts, fattened to the size of small sand bags, rested on top of her gut and barely contained by a stretched out tube top, her nipples outright tenting the fabric, but also a beast of a gut, large and expansive, with a deep belly button. This was no pot belly, this was a full on beer gut, which jiggled and grumbled, a steady stream of drool making it’s way down the front. Vinyl smiled a bit to herself, maybe she was just hungry?
        Making her way out of the room at a slow pace, every step needing to be a sashay for the best walking, Vinyl made her way into the kitchen of her home. The hefty mare marched her way right up to the fridge, before yanking the door open to gaze in. The sight that rested before her made her frown. It was all protean bars and slim fast and utter nonsense food! She furrowed her brow, beginning to curse whoever she had stocking this fridge, before a sight towards the back caught her eye, and brought a grin upon her lips. A large cake waited for her, tucked neatly away and hidden, but now it was in her sights. Without another moment of hesitation, Vinyl reached within and plucked out the cake, snickering to herself as she made her way back over to the counter of her kitchen, sitting on one of the stools and setting the cake upon the counter.
        There was a loud groaning sound, before suddenly Vinyl yelped, the old wooden stool shattering under her butt, and scattering around, the large mare landing onto her rump with a thud. Vinyl grumbled slightly, glaring at the chair and rubbing her slightly bruised derriere, before she went through the effort of getting back onto her hooves. Kicking away the splitters of the old stool, Vinyl tugged two stools together, before sitting her rear down. The mare released a pleased sigh, one stool for each cheek. The adipose oozed over the sides of the stools, her fat ass and hips much more grandiose than the average pony, thighs wrapped in layers of meat, yet Vinyl didn’t care. Her stomach growled, eyes zeroing in on the cake before her, as she began to drool even more heavily.
        The decadent DJ dove into the delicious dessert, not even caring for silverware or table manners. She knew only one thing, that she hungered, and this was the key to sating that hunger. The mighty mare tore into the cake with her hands, shoving large handfuls into her awaiting gullet, getting frosting and cake bread all onto not only her front and chest, but also onto the counter. Vinyl Scratch made short work of the cake, before leaning back and giving her gut a happy pat. There was a rumble, before she suddenly grunted, and out of her ass, she unleashed a torrent of hot, rushing, dark blue gas, the colorful toxins blooming from her rear and racing over the floor, those fat ass cheeks slapping together. Vinyl Scratch released a sound of content, before her phone began to vibrant in her cleavage. The mare huffed, before plucking it out to see who had disturbed her morning routine. 
        The lock screen of the phone was Vinyl Scratch, lithe as a twig, well groomed and maintained despite being a party gal, hugging onto an equally thin Octavia Melody, even more refined than Vinyl! Vinyl blinked a few times, finding it quite odd, before opening her phone. What greeted her then, was a text message and a picture. It was a picture of Vinyl, but she was an utter lardball. Fat enough to begin scraping at the category of obese, stuffed into a tube top and some hot pants, covered in sweat, tufts of blue hair poking out from under her arms and out of her waistband, a mighty bulge in her crotch that was not there before. Vinyl grinned at the sight, slowly licking her lips at the vastly improved image. First, she glanced to the sender. It was Pinkie Pie, of all Ponies….then, she scrolled down to read the text.
        “You’re welcome for the makeover. New party tonight, bring Octavia for some real fun!” Vinyl found herself grinning wider and wider as she read those words, the delight of last night’s party becoming more and more clear in her mind. She idly licked at her sausage fingers, while grinning to herself. Oh yeah, tonight was going to be one hell of a party.
        

> The Night Before
> --------------------------------------------------------------------------

        A Pinkie Pie party was somewhat of a legendary event in the small, not so sleepy town of Ponyville. Not only was it the pony’s special, unique talent, but it was a talent that she had been shaping, refining, and cultivating ever since she was a small filly. So, when in Ponyville, invites went out, you can bet your rump that anypony who got one would set anything that night aside to consider going to such a rockin event. It was just how things went in these parts, and it was on this most auspicious night that Pinkie Pie intended to use it to her full advantage. 
        One mare who had received one of Pinkie’s invitations today was Vinyl Scratch, better known by her stage name as DJ Pon-3, and honestly, she felt more than a little excited over the prospect. To many ponies, a Pinkie Pie party was just a chance to cut loose, have some fun for a night, not give two bucks about the next day. For a pony like Vinyl, it was a chance to show off her stuff. Pinkie might have been Ponyville’s greatest party thrower, but that didn’t mean she was the only party pony. Everypony had a reason to throw a party sometime, and for Vinyl, if she made a good enough impression at a Pinkie Pie party, those would be the ponies who hired her on to play at their stuff too. Had to make that dollar dollar.
        The area around Sugarcube Corner was packed to the brim, ponies chatting and waiting, gazing at the building itself. Mr. and Mrs. Cake were out of town, so Pinkie Pie had the place all to herself for her party needs. The windows were covered, and the door was shut up tightly, yet they could still hear sounds going on within. Whatever last minute prep work Pinkie Pie was doing, she couldn’t let any of the outsiders see. Vinyl Scratch just snickered slightly to herself, shaking her head and pushing her cart of musical equipment towards the back entrance. Maybe Pinkie Pie was just waiting on her?
        The backdoors to Sugarcube Corner were pushed open before Vinyl’s cart, and instantly the mare was hit with a semi truck of different sensations. The very first and most evident of the feelings was how damn hot it was inside the building. Vinyl felt like she’d start sweating any second now! She just shook her head, giving a small huff. Maybe Pinkie was waiting to turn on the AC or something? Yet, that was hardly the only thing amiss. There was some type of fog that coated the floor of Sugarcube Corner, a thick pink smog up to Vinyl’s ankles. She stared down at it, her nose scrunching up at the strange, sheer stench to it. It was sweet, but too sweet. Like when something got overly ripe, or when someone poured in way too much sugar, not even addressing the underlying foulness to it. 
        Beyond those things, the sight that Vinyl saw was something else altogether. The kitchen area was a total mess. Pots and pans and placed tosses about, covered in the debris of food preparation and probably consumption as well. The more Vinyl looked, the more of a mess it appeared to be, as if Pinkie Pie had abandoned all care while making the food, resulting in a total mess. Vinyl knew that Pinkie Pie was a carefree spirit, but this seemed to be more than her typical ridiculousness! Suddenly, Vinyl’s ears perked up high on her head, as she heard a loud thumping coming towards the kitchen. It sounded...like hoof steps. Her eyes flicked towards the door. Those footsteps sounded a hell of a lot heavier than Pinkie Pie’s typical bouncing.
        The figure, no, the visage that entered in through the doorway made Vinyl’s mouth outright drop at the sight of it. Sure, the hide and mane were both Pinkie Pie’s signature pink coloration, yet at the same time, the DJ was finding it difficult to accept that the mare in front of her was Pinkie Pie. The Pinkie Pie she knew was a little tubby from all the parties she liked attending, sure, but the mare in front of her was more like a pig than a pony. Body covered in fat, face rounded out to posses rosy cheeks and a jiggly double chin. Tits that had given up their perkiness in preference to being spheres of fat to rest on that gut, and what a gut it was. It was large enough that Vinyl was sure a colt or filly could fit inside of the saggy dome, hanging over her crotch. Those hips, Vinyl was pretty sure that Pinkie Pie had to waddle everywhere now, and that if she set a wine glass on that ass, it’d stay upright.
        The weight wasn’t the only thing to shift, either! Vinyl spotted the little things now, eyes looking up and down Pinkie Pie’s frame. The mare’s entire frame was covered in a thin sheen of shimmering sweat, more like a slime really, slowly dripping and puddling below her. Her face, chest, and hands were covered in the crumbs of past meals. Peeking out from not only under her arms, but rising up to her belly button, was thick, coarse pinkie pie mane colored fluff, which Pinkie idly scratched at, her body barely contained in a messy tank top and a pair of booty shorts, stretched over her ass. The mare even had a sort of aroma around her, a thick, heady musk that seemed to overpower the smog, Vinyl’s nose scrunching even more.  Yet, that wasn’t even the biggest change of all. No, the biggest change was, without a doubt the source of the musk, the mighty package stuffed into the front of Pinkie Pie’s booty shorts. It looked to be about the size of Vinyl’s damn head, still flaccid yet compacted like that.
“Pinkie Pie...what the fu-” Vinyl began to question, before Pinkie Pie just made her way forward with surprising speed, and shoved a cupcake into Vinyl’s mouth. The DJ yelped, an explosion of flavors filling her mouth. Pinkie Pie held a single finger over Vinyl’s mouth, forcing the mare to slowly chew the cupcake, savoring the frosting, the cake, and the sudden creamy center, and swallow, before giving a small groan, her eyes lidded. What in the world had Pinkie put into that cupcake!? The Pink mare just giggled innocently.
“It’s Pinkie Prick now, on account of my brand new appendage…” Pinkie giggled a bit, leaning onto Vinyl, her sweaty form oozing slightly onto the other mare, staining the clothes Vinyl had picked out just for the party. “It was good, wasn’t it?” Pinkie Prick teased, the other mare just giving a few slow nods, softly groaning, mind reeling at what the hell she’d just eaten. “Good. I already have a DJ booth set up for ya, tracks and everything, with a BIG plate of cupcakes set up just for you. Just go out there, play, and eat your cupcakes.” Pinkie Prick smiled, swatting Vinyl on the ass. The other pony nodded, before walking out of the kitchen and to the new DJ booth Pinkie Prick had set up for her.
Vinyl flopped into the chair, her horn lighting up to start playing the music, laying down the beats, while her hands reached out for the platter of cupcakes. Part of her mind feebly tried to resist, looking over the rest of the room. There was so much food, tables utterly stacked to the brim with sweets and pastries and other confections of fattening goodness. How had Pinkie gotten that dick, what was in the cupcakes, what was this party really about!? The second Vinyl bit into the second cupcake, all those thoughts flew away. She simply leaned back, giggling idly to herself, savoring the fantastic baking ability of the party mare in her mouth. It made her whole body tingle, a warmth filling not only her stomach, but her crotch as well. It made Vinyl simply crave more of the treats, so naturally, she reached for another...and another.
The doors to the party opened up, ponies walking in and instantly noticed the things that Vinyl herself had noticed. The sheer heat of the room, the smog that occupied the floor entirely, the mountains of food piled up on the far tables. Had it been any other pony, chances are they would have simply turned and left. Yet, this wasn’t just any other pony. This was Pinkie Pie, after all! That thought in of itself put minds at rest, but those who could shake off that, found their worries being pounded away by each and every pound of the bass in their ears. This was a party, after all, and things like this only happened at parties.
So, the crowd dispersed into the room. Some danced, some spoke in groups, some stood by the walls as wall flowers, but no matter who they were, every last one of them ate. Not just a simple snack, a simple pastry. As was shown with Vinyl, who was eating cupcake after cupcake, not caring how the crumbs and frosting stained her mouth, bits of it collapsing onto her chest, some staining her hands, they just couldn’t stop with one. They only had one thought towards the food, and that was more. By the time Pinkie Prick revealed herself, the entire party was under her spell. All eyes turned, the beats pounding in their head, and with the beats, they found new thoughts. How desirable Pinkie looked, how carefree and gorgeous. She was a truly natural mare! No, she was more than a mare. So much better than a mare, or a stallion! An utter shestud.
Pinkie Prick smiled, beginning to sashay her way through the party, each step making her form jiggle, her ass quaking and wobbling, gut shuddering softly. The front of her hot pants gave out a loud groan, the meat of her dick starting to slowly harden, thicken, pressing out against the fabric. On her walk, her stomach gave a loud gurgle, before the shestud suddenly unleashed a pink miasma from her ass, the gas rushing out, cheeks slapping together as the shestud unloaded. Her face was one of total content, the cloud rising up behind her, all eyes watching, glazed over and filled with desire. When it finally ended, Pinkie Pie just giggled, and returned on her trip to the DJ booth.
“Heya Scratchy, liking the party?” Pinkie Prick asked, walking around the DJ booth and leaning against one of the speakers. Vinyl blinked a few times, looking up from her cupcakes. Her mouth was covered in frosting, hands and chest covered in crumbs. Pinkie Prick smiled softly, while Vinyl just grinned and gave a nod. “Better question...Are you liking the new me?” Pinkie Prick asked, pushing down her booty shorts. Her cock utterly flopped out, free of it’s confines and bobbing in the air. It was at least two feet long, balls as large as grapefruits, bobbing there in front of Vinyl, letting her musk wash out over the mare.
“Oh...Ohhh yeah….” Vinyl grinned dreamily up at the shestud, who simply giggled softly, idly rubbing her dick.
“Do you wanna be like me, Scratchy? Big, sexy, powerful? A total shestud? A cock in your very name, totally gay for dick and ass?” Pinkie Prick grinned, the beats of the song beginning to shift to a more bubbly tone. Lyrics filling the air, sung by Pinkie Pie herself, rather lewd in nature, yet impossible not to dance to.
“Y-Yeah, definitely! Who needs Vinyl Scratch? make me Vinyl Shaft!” Vinyl grinned, looking up at Pinkie Prick eagerly. The shestud chuckled, before tearing off her booty shorts, and tossing that sweat stained garment into the crowd. 
“You got it…” Pinkie Prick said, before turning around and sitting her fat ass on the unicorn’s face, feeling the cheeks part, that muzzle getting shoved between them along with Vinyl’s horn, moving to be right up against her donut thick pucker. The shestud gave no warning, before beginning to unleash another blast of her thick, powerful smog, washing out over the DJ and filling her senses, while Pinkie Prick just settling her head in her hands, snickering. It was gonna be a long, fun night.

> Octavia's Wild Night
> --------------------------------------------------------------------------

        Octavia stepped away from the train that had just arrived from Canterlot, letting out a rather relieved sigh, before taking a nice, deep breath of the Ponyville air. Typically, the air of Ponyville was fresh, clean, the kind of air that one could only get out here in the country! Yet, Octavia took in that breath, before suddenly coughing and gagging, taking in a powerful, foul scent. The cellist shook her head, before glancing around the train station. Had somepony forgotten to empty out an ever flowing trash bin? No. The sight that Octavia’s eyes rested on was much...much worse.
        It was a pony, like any other pony, Octavia had seen her sometimes around Ponyville, believed her name was Lemon Heart, but she was different. Changed from when Octavia last saw her. The Lemon Heart of the past had been a thin, sweet mare. The mare who Octavia stared at now was what some ponies would call a beast. She was large, bulbously fat, really. A body completely covered in flab, an ass as big as a bench, a gut which wobbled with every movement. Face, wrapped in blubber all around. More so than that, though, she was utterly vile. Sweat caked her form, specifically where the fat folded or creased, while under her pits and from her crotch, gnarled hair the color of her mane grew out in thick patches. An odor permeated the air around her, and her crotch...Octavia retched slightly in her own mouth, at the sheer girth barely contained by the mare’s pants.
        “What’re you looking at, twig?” Lemon Heart snorted, turning her fat, flabby face to look at Octavia. Octavia blushed and sputtered, before her eyes drifted down, and widened in shock at what she saw. Another mare was on her knees, seemingly dazed, while a thick cloud of flatulence loomed around her. Lemon Heart grunted, before suddenly releasing a loud trumpet report, and spraying more thick, yellow colored gas out of her rear, washing over the mare, who could simply groan and shiver, her eyes flicking with something. Seemingly...desire.
        “N-Nothing! I’ll just be on my way!” Octavia said, giving a small bow of her head, before picking up her cello case and turning, hurrying away from the vile sight of the other mare and her victim, stepping away from the train station and getting into Ponyville proper. Maybe she should alert somepony about this, like the guards? Yet, the moment Octavia got into Ponyville proper, she could tell something was off. A quick glance around confirmed her suspicions, sending shivers down her spine. Lemon Heart back at the train station, she wasn’t the only warped mare! They were all around Ponyville, each one as bad as Lemon Heart had been! Large, fat, crude and with those bulges in their trousers. The only ponies they seemed to have any decency for, were other mares like themselves. Octavia swallowed down a lump which had formed in her throat. What was going on in her town? She had to get home. Maybe Vinyl had some idea.
        The walk home felt like it lasted forever, Octavia constantly looking over her shoulder, staying at the ready. Whatever possessed the mares who had been changed, whatever drove them, Octavia didn’t want to find out. She’d hate to be subjected to any of those beasts. They were so vile, it was absolutely repulsive! Maybe she’d have to get in contact with Twilight, and her lot? Try and convince them to do something, possibly fix the mares who’d fallen under the thrall of this unknown force! Octavia simply refused to accept the thought that this was natural, by any stretch of the imagination. Ponies simply didn’t change so drastically over such a short amount of time, and especially not in such a horrid manner.
        The door to her and Vinyl’s shared cottage swung open, and Octavia stepped in. Vinyl might not have been the most cautious mare in Equestria, but there was no way that she’d have fallen into such a trap as the rest of the mares did. Octavia took a few slow steps inside, listening carefully. There was no loud reverberations of bass shaking the house, so either Vinyl was asleep, or she was away someplace else. Octavia stepped forward, setting down her cello against the entrance hallway wall, before walking into their kitchen. 
        “Ugh, Vinyl, what in the name of Celestia…” Octavia frowned, staring at the mess that’d been left on the counter top. It looked to be, judging by the debris, what had once been a cake. The mare had left her plate out, and seemingly had eaten the entire thing! Octavia was not living with a slob. Octavia just sighed, before making note of something on the counter. A note, left over by Vinyl. Octavia blinked, before reaching out and grasping the note, plucking it up into her hands to read it.
        “Tavi, Pinkie is hosting a party at Sugarcube Corner, and I’d love if you could come. I’ll be busy setting up there, so you probably missed me. Sorry I couldn’t be there to welcome you home. See ya at the party!” Octavia read allowed, the note written in Vinyl’s typically messy handwriting. The cellist frowned, looking the note over before setting it down. Well, she could actually use this to her advantage. Knock out two birds with one stone, as it were. See how Vinyl was actually doing, and beyond that, get to Pinkie Pie, and by extension, the rest of her friends to get to the bottom of the oddness that was happening around town!
The walk to Sugarcube Corner was filled with just as much tension as the walk to Octavia’s own home had been, if not more so considering that she was heading into enemy territory. The air itself had been befouled by the behemoths that now walked the streets, moving with confidence and superiority. Octavia avoided them, keeping a close eye on the moving mare mountains, a frown firmly placed on her lips. This was not good, not good at all. Had this come in from another town, or was it a Ponyville born problem? Considering the track record of the sleepy town, Octavia didn’t doubt the latter. The former was much scarier.
Octavia saw Sugarcube Corner in the distance, ponies of all shapes and sizes going in. Even from here, she spotted them, Twilight and the rest of her friends, besides Pinkie Pie. Octavia felt a breath of relief. They seemed perfectly fine and normal, so there was still hope! Octavia just had to get to them, and see if they had a plan. At the door to the party, though, Octavia was stopped by one of the large mares. She was thankful that it wasn’t somepony she knew, but the fact that they were here at all was enough to be unnerving.
“Octavia, right? Yeah. Vinyl said that you’re supposed to go in through the back and meet ‘er.” The mare nodded, gesturing with a grubby thumb back towards the side of the building. Octavia frowned, looking past the door into the party, before sighing. She couldn’t see anything important from this point anyway, and there was no reason to argue with the other mare. She wasn’t barring Octavia’s progress, just saying she had to take a different route into the party. The mare just gave a single nod, before turning and beginning to walk around the side route towards the back entrance.
Octavia opened the back door slowly, before suddenly freezing in place, eyes growing wide with horror at the sight of what awaited her in the kitchen. It was Vinyl Scratch, yes, but it was not her Scratchie, not in the least. This mare was large, jiggling with fat and oozing out sweat, a thick aroma around her, the same tufts of hair as the others, and that bulge in her pants, just twitching there. Octavia took a few steps back, before Vinyl gripped her with her magic and tugged her in, closing the door behind her.
“Tavi, babe! So good to see you, back from Canterlot!” Vinyl grinned, dragging the cellist right up onto her gut, hugging the mare. Octavia gagged, pushing against the blubbery mare, trying to ignore the thick stench, or the greasy feeling of Vinyl’s body against her own, seeping into her clothes, befouling her. 
“V-Vinyl! What in the world happened to you!? What is going on around this town?!” Octavia asked, still struggling in the oddly powerful grasp of the fattened mare, who just grinned a bit. Vinyl didn’t say a word, instead she kept a hold of Octavia, and turned her around so that her back was pressed against Vinyl’s front, and turned them both to face deeper into the room. Octavia’s blood ran cold, as she saw the host of the party itself, Pinkie Pie, standing there in the doorway, just as massive and slovenly as the rest of the mares, if not worse off. Pinkie Pie giggled a bit, walking up to Octavia.
“So, ya wanna know what happened to this town…? Why, simple, silly! I’m going around and turning all you goofy, plain, boring mares into sexy she studs! Giving confidence boosts all around!” Pinkie Pie beamed, a grin on her face. 
“H-How can you do this!? This is wrong! The rest of your friends, they’ll put a stop to this!” Octavia declared, struggling against Vinyl’s hold, unable to slip from those flabby arms. Pinkie Pie just smirked, good and wide while looking at Octavia.
“Why...My friends are out there right now, enjoying their brand new dicks! Now, just sit back and relax, Octavia...Me and Vinyl are going to help you fit riiiight in…” Pinkie Pie smirked, winking to Vinyl. Vinyl sat down, tugging Octavia along with her, so that she was lowered. Pinkie Pie didn’t waste a moment, dropping her pants, letting that long, thick member flop out. Octavia’s eyes widened in horror, wondering if that was what she was going to be subjected to, beginning to shudder and tug against Vinyl.
Pinkie Pie just giggled, before turning around. Octavia stared at the ass which loomed over her, the pink full moon exuding a strong musk outwards. Already, Octavia could hear Vinyl behind her, taking in heavy breaths into her nose before groaning with sheer delight. It was obvious that the DJ was already completely enthralled to the pink derriere and all that it represented. Slovenly nature, obese forms, bulging cocks, and just general superiority! Octavia struggled in Vinyl’s pudgy grip, surprised at the strength which the unicorn now possessed. It was as if the ponies afflicted by this were hardly even ponies anymore, but something completely different altogether.
“Vinyl, let go of me this instant! I’m sure that the princesses can still fix this, fix all of you back to your normal selves! You cannot possibly enjoy being such a filthy, vile slob!” Octavia declared, tugging against those flabby arms once more. Vinyl only released a deep, husky chuckle befitting of her new, surplus form. 
“But Tavi, it feels sooo good! Letting go of all those dumb, silly rules that don’t mean anything, giving in to the stuff that feels good. To be a hot, confident She-stud instead of some flighty mare… Mmmm, I can’t wait till you get rid of that lame cunt and have a real dick. A nice, fat ass to fuck...mmf.” Vinyl groaned softly, Octavia feeling a pressure pushing against her rump, Vinyl becoming aroused by the mere ideas of which she spoke. 
Octavia opened her mouth to refute the words which Vinyl spoke, but the chance was stolen away from her. Vinyl shoved Octavia’s head forward, plunging her between those two fat cheeks, the layer of slime that covered the ass helping to lube the way and drive Octavia in deeper. The cellist tried to push back, tried to resist, but even Vinyl’s magic seemed stronger than before, pushing Octavia until she was placed right up against Pinkie’s doughnut of a pucker, the seeming source of most of Pinkie’s rump musk.
“Finally, I thought you two were gonna gab on forever! Ya goofs... Now than, Shafty, let’s get to fixing up your mare into something even better! Cocktavia, here we come!!” Pinkie Pie giggled, before her stomach gave a loud gurgle. Without another word, her ass began to unleash a rush of her toxic pink gas, all of it blowing directly into Octavia’s face. That which rushed past, Vinyl happily inhaled, but the majority was all meant for Octavia. Octavia clamped her mouth, nose, even her eyes shut, intending to resist the foul corruption for as long as she could. Surely, she, a Melody, could outlast these two slobs?
At first, Octavia thought that her plan might actually work, too. She was a hardy earth pony, after all, and natural endurance in all things was one of their perks. That is, until a pair of thick hands ripped off the blouse which she was wearing, and began to fondle at Octavia’s breasts. The cellist released a sudden gasp at the feeling, and it was at that time that the pink gas seemed to take it’s chance. Rushing inside of Octavia’s mouth, the mare coughed and sputtered, but already the foulness was within her. Octavia’s whole entire body felt numb, betraying her, as Pinkie was able to add only more and more.
Vinyl’s attentions didn’t stop, either. The slovenly DJ’s hands kept rubbing and groping Octavia’s breasts, her horn lighting up and tugging down both of their lower body garments, her eyes filled with desire. She knew exactly what she wanted her beloved to become, a sexy, confident, powerful she-stud like herself. Her throbbing cock easily slid up between Octavia’s rump cheeks, the fat DJ grinding without a care, further distracting Octavia from the efforts she was putting forth to try and ignore the advances of Pinkie or her gas.
Thanks to Vinyl’s efforts diverting Octavia’s attention, distracting her with the hands on her breasts and the cock teasing inside of her ass, the cellist failed to notice as her body shuddered, a heat growing and beginning to spread out from her and out to her entire being. The first, and most obvious change, was the steady collection of adipose on her form. At first, it was simply focused on Octavia’s stomach, turning what was once as flat as a board into a good and proper pot belly, with no intentions of stopping there either it seemed. Her selvet, lithe frame was becoming properly buried in a layer of flub, her breasts thickening, ass plumping, and as much as Octavia attempted to resist, to deny the changes, she couldn’t deny one simply fact. It felt good.
Weight was hardly the only thing changing about the cellist, either. The heat in her frame raised, slowly producing a steady sweat to ooze from herself, a slight layer of slime covering her fattening form just like the pair of slobs which held her captive. Her body gurgled, the internals themself seeming to change. Even her saliva glands kicked into overdrive, slowly starting to ooze over her plumped lips. Her mind, during this time, was utterly assaulted by images and urges that were strangers. The desire for dick, for ass, to show off her superiority! To rub her slovenly nature in others faces. Octavia groaned, trying to cast the ideas out, but they only came on heavier.
It eventually all came to a head, as a fire seemed to burst in Octavia’s loins, the mare moaning loudly at the sudden sensations she was filled with. Her clit grew, at first engorged, before beginning to swell more and more, thickening, plumping, changing shape into something much more proper. Her ovaries within shifted, and before long, a pair of hefty testies dropped from Octavia’s slit, the area around there shifting, changing into a truly proper, seamless cock and balls, throbbing shamelessly in the air. Within moments, Octavia was experiencing her first orgasm. It was a truly undeniable sensation...Being a shestud felt good.
Pinkie Pie stepped forward, Octavia’s head popping free with a gross, wet shlick in the air. The party mare turned around, and grinned wide at the sight in front of her. The old Octavia was totally gone. The area around her muzzle was stained pink from the gas, but Pinkie Pie knew that soon it’d be replaced with food, a steady stream of drool exiting over her plump lips. Her face had rounded out, becoming chuberic, jiggling slightly from each breath, chin engulfed with flub. Shoulders and arms had thickened considerably, dexterous fingers now more like sausages, thick tufts of black right in her armpits. Her tits were bags of fat, resting on top of her hefty, double rolled gut which filled her lap, a forest of black rising over her gut to the belly button. A layer of slimey sweat covered her frame, and already she was ripping ass around Vinyl’s dick, the other slob shuddering in delight, hands eager groping the new Octavia, from her seat filling ass, to jiggling those love handles, the tree trunk sizes thighs, whatever she could get her hands upon. These two had a lot to enjoy together.
“So, how you feeling, fat ass?” Pinkie Pie asked, wiggling her eyebrows. Octavia looked up at her, furrowing her eyebrows, opening her mouth...before releasing a loud, thundering belch, her entire frame shuddering and jiggling, before she grinned, slapping her gut.
“I feel bloody fantastic, you fat twat.”
