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.
