(Various M and F to Pokemon)

“Vince, you sure about this?” Rianna looked to the small pill in her hand. It reminded her a little of Tylenol, except flattened into a circle. Half was white, half was red, and there was a thin black stripe down the middle. A small ‘108’ was etched into the surface in blue.

It wasn’t that she didn’t trust him. Actually, it was the opposite—she knew him so well that she trusted he was leading her into a mistake. Of course, given that the last few mistakes he’d taken her on had been the best nights of her life, he got a pass.

“Trust me, the guy who got us in here promised that this would be a night unlike any other. Completely life-changing.” Vince smirked. His own tab had a ‘59’ marked on it, which was a little weird. He’d have expected any tabs to share the same dosage… But maybe this was some kind of serialization, to make sure everyone at the club got their own special trip to party town.

The weirdest part was how familiar the design was. He could swear he’d seen something like it before, but couldn’t quite place where. He looked to it curiously, but then a loud ding filled the air, along with another sense of déjà vu.

A series of notes had played that reminded him of childhood car rides, like an old game or something. He thought about mentioning it to Rianna, but then realized that she’d just laugh at him for being sentimental and old—even though he was just six years older than her. It wasn’t his fault she had a thing for trying to teach old dogs new tricks.

A tinny voice crackled over the speakers. “Ravers on the floor, who’s ready to make some noise! Drop and roll with me!” Mercifully, the music that followed was crystal clear. Vince hated mixing fun with static, it never led to a good trip.

He pressed the tab on his tongue, feeling it fizz away in seconds. There was a strange spice to it, almost like a cinnamon. His throat burned a little, in a good way. He’d let that heat roll him through the night. A smile broke across his face and he grabbed Rianna’s hips. “Ready for a good time?”

Rianna’s tab was a lot more… drooly. It was a lot like some saliva gum she’d had on a dare, the kind that had made her mouth water out of control. She gulped down a mouthful of the stuff, surprised at just how… Normal it all was. There wasn’t really much of a taste or an aftertaste to it, just that tingly mouth-watering that told her she was in for a wild ride.

Neither of them had any way of knowing that they were tasting, were feeling, something very different from each other; nor would they get a chance to tell each other. But both would find out very, very soon.

The music carried them into the night, and neither noticed the first symptoms. Of course, even if they had, it would be much too late to do anything about it. In a way, it was almost merciful. The flashing lights covered the fact that the ravers’ skins were shifting in hue, and the strobe kept them from focusing on each other’s faces.

Rianna’s olive skin was lightening, taking in a pinkish sheen that positively glowed when it was lit up. Her bare midriff, normally a bit paler than the rest of her, was getting whiter still. Cream-colored stripes tingled along her body, tickling her and guiding her dance.

Vince watched her move, panting like a mad dog. He couldn’t help it, there was so much of that heat in his gut. All the hairs on his chest were standing on end, and it felt like they were puffing out his shirt. That same tingle came across his beard and collar, warm and itchy. Little did he know, his beard was taking on a tan shade, while his chest was covered in dark fur.

“All right, I’m having fun!” Rianna shouted, laughing. “But I thought this was thuppothed tuh bwuh thpethull!” Her tongue flopped from past her lips as she spoke. She couldn’t help it, it was like it belonged hanging past her chin.

Vince laughed with heartfelt roar, sticking his own tongue out and shaking his head from side to side. His ears felt like they were stretching and flopping slightly with the motion, and it made him smile wider. “Hell yeah!” He grinned, running his hands along the sides of his head, finding much more hair than he was used to.

Before he could focus too much on that, he bumped into the girl behind him. She grunted, but barely budged—probably because she was so heavy that most of her body was threatening to spill past her skimpy outfit. Which was weird, because Vince could have sworn that a smoking blonde was right behind him. Not that he would ever look

“Hey, sorry!” He called out, focusing more on his date and how hilarious she looked sticking her tongue out like she was at some kind of metal show. She wasn’t the only one, some dude was really flipping, waving his tongue around so much that it actually wrapped around his neck like a scarf.

“Lax!” The chubby girl called back. The music drowned out her cry, and the pop of her jeans surrendering the fight. A blue-and-cream-furred gut spilled out into the open, making her stagger and wobble her arms out at her sides.

Rianna would be looking at the swollen girl, except she was focused more on the strange sight of the guy beside her. He wasn’t exactly strapping before, but now he looked a lot softer. She had sworn that he’d had longer curly hair, but now it was done almost like some kind of Viking girl’s. Also there was the fact that his hips were practically bulging out of his jeans.

“Woo-oo-oo! “ He half-shouted, half-bleated. It was in time with the music though, so Rianna set it from her mind and went back to dancing with her partner. By now she barely noticed that she was slobbering all over her top, she’d gotten so used to moving with her tongue out.

Some of the other couples were a bit more observant.

Two girls had gone from kissing to inspecting their new overbites, brows furrowed in confusion. One of them couldn’t keep her arms from her sides, a purplish wing connecting them beneath her fingers, which were posed like pincers. The other hunched forward, her backpack bulging as a budding flower threatened to push it off of her body.

One young woman tried desperately to calm down her hopping boyfriend, who couldn’t seem to stop himself from hopping up and down eagerly. His ears flopped with each jump, now tipped with fuzzy cream pom-poms, and a similar fluff coated his wrists and ankles. She didn’t quite get as far as touching him, but her cupped hands tugged at his piercings each time she got close, a mite of magnetism drawing them together.

On the floor, two young men who’d started to do ‘the worm’ had found themselves unable to rise. One of them was getting rounder, white blubber slapping against the floor with each push of his increasingly finlike hands. The other was growing thinner, stretching wider as his hoodie was pushed from his head by a growing purple hood.

Vince looked to Rianna excitedly, unable to keep his backside from wiggling. A heavy, long tail poked from his waistband and he barked out an excited. “You know what, I give this place a nine!” The last word came out louder than he’d intended, and also wasn’t the ‘eleven’ he’d thought he was going to say.

He paused, raising his hands up to his neck. “Elevuhnine! Arcleven. Elvuhnine, nine!” Weird. He’d always been well-spoken when high—as far as he could remember. It must have meant these doses were really worth it.

Rianna watched him with growing interest. She had no idea why, but today he was way hotter than usual. Just hearing him call out like that… She pressed her chest against his, absently noticing how good his fuzzy chest felt against her pudgy belly. The fact that she’d been skinny minutes ago didn’t cross her mind in the slightest. Instead, she was completely fixated on wanting to know how he tasted.

She mashed her lips against his, eyes rolling in her head as his strong arms encircled her waist. Her tongue bulged, stretching his lips and wetly sliding down his throat. She couldn’t help herself. It was the most intense need of her life, one that was so vivid that she didn’t even notice the sensation of her backside stretching out into a tail.

Vince was taken aback—not just by his girlfriend’s drooly assault, but by how little he was bothered by practically swallowing her swollen tongue. Some small part of him insisted that he pay attention to something about that. But that part wasn’t getting mouthfucked by his girl of his dreams.

“Mwuhkuhnhyynn,” he slurred around her tongue, feeling that heat building in his chest again. He tried to hug her tighter, but his arms weren’t as flexible as they should have been. Neither were his legs, for that matter. All it took was one bump from the swelling girl behind him to send him falling forward, landing onto his newly-plus-sized girlfriend’s body.

“SNORRrry!” The fattening stranger rumbled, finding herself soon distracted by her date’s wooly body as he pressed himself against her, nuzzling her bulging, fuzzy belly.

The heat in Vince’s chest kept growing, and with a sputtering cough he released some of it out. A faint trail of steam slipped from the space between his lips and Rianna’s, and she instinctively pulled her head back in surprise.

It wasn’t that it hurt, her tongue was much too drooly for that. The steam was just a surprise, and enough to make her withdraw her massive, prehensile tongue from deep within her boyfriend’s throat. A small sputter of fire burst past his lips a second after her tongue was free, and she yelped in surprise. “Lick!”

Vince didn’t need to be told twice. He darted his head in towards her shoulder, licking her throat with a tongue that was increasingly rough. It wasn’t much different than a dog’s tongue, except for the heat that was pouring from his mouth. He nipped at her throat, purring out a rumbling “Arc.”

By now Rianna was sure that something was wrong, but she just couldn’t find the words for it. She could feel her arms and legs shortening into her body, turning her form a lithe and slinky party girl into some pudgy, dumpy creature. She tried to call out to Vince again, but could only shout out a “Tung!”

Vince took the hint again, cupping Rianna’s tongue in his hands. It was so long, the wet and drooly thing was basically like a body pillow. For some reason, he loved it. His fingers twitched beneath her changed tongue, and he didn’t notice them shorten into the bulging digits of a paw. Instead, he was much too busy playing his tongue against hers, even rolling his neck into every lick like a dog with its favorite toy.

Funnily enough, they weren’t the only ones on the floor engaging in tongueplay. The man whose tongue had stretched into a scarf was now distinctly froglike, and pressed tightly against what looked like a pink-and-black man-sized teddy bear. The creature had once been his date, which explained how passionately the two of them were kissing… Or doing as best they could, given the tongue in the way.

The surrounding onlookers didn’t share the two’s enthusiasm, and were doing their best to edge away from the duo. One of the nearby men found it easy to literally take wing, beating his new feathers to launch himself into the sky—only to get tangled in his old clothes and drop atop a whale of a girl. Another girl found herself similarly aquatic, her neck stretched far from the shell that now weighed her turtle-like body down. She flapped her new fins in a panic, even as a horn pressed its way out from between her eyes.

A couple that had been gym rats were now reptilian-like animals, covered in scales. What had been the man of the house was now sporting blue scales and what looked like distinct bulging breasts; while his lovely lady was now on all fours, spiky and purple. She aggressively stood between her man and another girl who’d been ogling him. This intruder’s body was cloaked in shadow, though her doll-like silhouette was as visible as her long, heavy tongue and her lust-addled red eyes.

Vince caught sight of this through his peripheral vision and froze. Those… They were Pokemon! “Arcy NINE!” What was meant to be an expletive instead burst from his face with enough force to give him a fuzzy snout, and he splattered his Lickitung girlfriend’s face with drool.

The speaker crackled to life once more. “It seems most of you have noticed how tonight’s going to go… And others are already having fun. So let’s crank it up to eleven, you crazy monsters, you.”

The building’s sprinkler system chugged as it poured a new chemical onto the writhing mass of humanity. It was crisp like alcohol, cool on the skin and evaporating in instants—along with everything the occupants had brought with themselves. Clothes, shoes, purses, wallets… No trace of their old lives remained, exposing a room full of Pokemon.

At the same time, they each found themselves losing more and more of their inhibitions. As the liquid evaporated, it left an odor in the air that affected every last one of them, even those without noses. Cheeks flushed where possible, anyone who had a heart found it racing.

The Greninja and Bewear continued to passionately kiss, bumping into the awkward threesome of a Nidorino, Gengar, and Nidoqueen between them. A Lopunny mashed his Magnemite girlfriend against his feminine chest, tingling from the static she gave off. The swollen Snorlax similarly smothered her wooly Wooloo.

What had been Vince and Rianna didn’t care about any of that, they were too focused on each other. He pinned her beneath his Arcanine body, beaming at the addled look on her derpy face. Then she shoved her tongue into his mouth, and he succumbed to the addiction of her smooth, blubbery body. She didn’t last much longer, melting away beneath his warmth and the heat of his fur.

Would it last for the night? The day after? The rest of their lives? They didn’t know, and they were much beyond having the capacity to care.
