Kimma, Abby, and Erin were as close as friends could be. They were friends in high school, lived in the same suite in college, and now lived together in a small yet comfortable house. Thanks to this time with one another, they had done practically everything together—except transform.

Kimma was more than a little disappointed in that, having meant to try some TransFun and—in the company’s own words—experiment with a little change in their life. But Abby and Erin, ever conservative, had refused to let her buy a serum until they’d paid off their house in full.

Seeing as how transformation could lead to property damage, it was a smart and sensible decision. But it was also a torturous time for Kimma, who had to sit by and hear all of the stories her coworkers had of how much better life was with an occasional transformation.

The girl almost broke down when a TransFun shop opened in their local mall, and she would have changed into an animal without her friends knowing were it not for one fateful blog post, a testimonial as to how brilliantly TransFun could be used as a prank.

To Kimma, this was a perfect idea. She’d transform her roommates into animals with an extra dose of instincts, and then take a serum herself to join them on a night of wild fun. That very day, she bought a three-pack dose of poodle serum, and had smuggled it into her house at night.

But the girl had yet to use it, saving the serums for a very special day, one that had just arrived. After all, Abby and Erin had made a good deal of sense in agreeing to hold off on even thinking of TransFun before the house was truly theirs.

And now, on a beautiful and warm summer day, Kimma’s chance had come. The brunette beamed to herself, her dark eyes twinkling with mischief as she looked down at the plates before her. She’d offered to prepare some of her favorite beef stew, knowing full well the flavors would help mask the taste of TransFun.

Of course Abby and Erin agreed, suspecting nothing was awry. They had no need to: Kimma had been with them all day and would have no time to head down to the store in the mall. As far as the two girls knew, Kimma was just as excited about having a house to own as they were.

That said, Abby and Erin had also been keeping something from Kimma. They’d been secreting to the TransFun store in their free time, wondering what they should transform into for the first time. They’d listened to Kimma’s complaints and had been planning to surprise her. After all, she’d been so understanding about waiting to change that Abby and Erin couldn’t resist getting a transformation serum to please her.

Still, that was for tomorrow. For tonight... The girls looked on appreciatively as Kimma brought out three bowls of beef stew, a huge smile on her face. Stem gently curled from above the bowls' contents, and the both Abby and Erin's stomachs rumbled with hunger.

“Ta-da!” Kimma grinned, setting a bowl on their glass table, one for each of her friends. “I know this meal might seem a little special, but that's because this is a special occasion.”

Abby nodded contentedly, her blond locks swaying as she gazed further at the feast before her. “This looks professionally made, Kimma!” She squeaked happily.

Erin nodded as well, a smile as she regarded her fellow brunette. “Really, thank you very much for this.” She smiled and picked up her spoon, blowing on the liquid to cool it before drinking.

Kimma chuckled despite herself, wondering if her friends would be so appreciative when they were on all fours. Of course, if the serums worked then there wouldn't be too much of a problem. She'd just take her own dose and enjoy them in a night of doggy fun, as the box promised.

“Oh my God... This is probably the best stew I've had!” Abby groaned, hungrily devouring the contents. A slight flush appeared on her face as she started to eat, her hunger spurring her to eat faster.

“Did you add something to it?” Erin asked between bites, finding herself enraptured with the meal as well. There was a subtle hint of something she'd never tasted before; something that was oddly pleasing to her taste buds.

Kimma laughed to herself at that. If only her friends knew what she'd added! She managed to keep herself from unveiling her secret though, instead simply waiting for them to consume enough TransFun to transform.

“It's a family recipe.” She lied, a mischievous smile playing its way along her lips.

“Well, tell your family that it's delicious.” Abby beamed, shaking her head to toss out her light hair behind herself. But as she did, her ears moved as well. Kimma watched with excitement as her friend's ears grew long and floppy, just like the poodle that she'd become.

The brunette girl kept her poker face on as she sent a sidelong glance at Erin, chuckling as the girl's nose started to darken on her face. It grew wet and moist, its tip pressing back into a doggy button nose.

If either of the girls noticed the changes they didn't say, instead eating a little louder and sloppier as they grew canine appetites.

Kimma's heart raced at the sight of her friends beginning to change. This was really happening; her plan was working! She smiled and lowered her gaze as to not betray herself, only to have her eyes widen a moment later as she caught sight of Erin's skirt.

There was something entirely off-putting about the bulge that was forming in Erin's lap, and as Kimma watched it only grew larger.

“Oh my God, have I told you how much I love this stew?” Erin chuckled happily, feeling her body transform but not registering it. All she knew was that her meal was making her strangely horny, her groin hot.

Little did she know that the source of this change was a penis slowly slipping from between her folds. A pair of balls followed it, her labia sealing around them as though she'd never been female to begin with.

“Um. I can see that you do.” Kimma said nervously, staring at her friend's scrotum as it began to swell, a thin layer of fur covering it. She gulped hard, her worst fears confirmed as a long and red cock poked up from Erin's skirt, lifting the fabric with ease.

The girl began to panic at that. Erin would probably willing to accept transformation in her life—but not if her first change was into an animal of the opposite gender! What had caused this?

Kimma wracked her brain for answers, her face paling as she came to realize what had happened. That three-pack of serums that she'd picked up must have been for a little more 'doggy fun' than she'd anticipated! No wonder she'd gotten a sly look from the cashier!

Thankfully, Erin didn't notice. Instead, the girl found herself more and more aroused by the meal, devouring it in loud and sloppy slurps. She groaned happily and took bigger and bigger spoonfulls, eating with gusto.

Kimma breathed a sigh of relief, only to yelp aloud at the realization that her other friend was still transforming. What if Abby—

Her worried thoughts vanished once she caught sight of her blond friend. The girl was similarly devouring her meal, taking large and famished bites of it as though she hadn't eaten in years.

“Mnn! Kimma! This is really good!” Abby beamed happily at her friend, unknowingly exposing a set of lengthening canines. She then slurped some of the soup around her lips, similarly revealing a long and doggy tongue.

“Um... Yeah.” Kimma said unsuredly, wondering if her friends had noticed the changes and were just taking the piss. But Abby then kept eating, practically shoving her face in the bowl with how close her lips were to the stew.

Then the unthinkable happened. Abby's own nose began to darken, and as it flattened out on her face a new bouquet of scents slipped into her nostrils. She could smell every spice in the stew, the delectable meat. But before long, another meat wafted its scent towards her nostrils.

The blond blinked even as her hair began to brighten to a snowy white, her nostrils twitching as she searched for the source of this intoxicating smell. Her eyes widened as she caught sight of Erin's cock, and she opened her mouth as if to speak.

Kimma winced, realizing her charade was up. Abby had realized the changes that were happening to them, and she and Erin were going to somehow get some canine vengeance on their transformer.

But Abby surprised her by dunking her head into her stew instead of alerting Erin. Unattended, her spoon clattered to the ground as Abby began to loudly slurp at the delectable meal, her lips darkening just as her nose had.

She didn't know why she did it—she only knew that Erin smelled really, really, really good. So good that she had to distract herself by diving into her meal, to keep her mind off of anything but Erin plunging herself into Abby's wet and waiting folds.

Abby flushed more as she loudly slurped at her food, her manner as bestial as her thoughts. Her hands slipped to her crotch and the girl began to rub at herself lecherously, a lusty grin on her lips.

Kimma stared at this in slack-mouthed shock, her spoon clattering to her bowl as her fingers went numb. The sound was enough to snap Erin's attention up to her, and the increasingly doggy girl sniffed at the air with her canine nose.

“Sarrrmnthing wrrrong?” Erin half-growled, her head cocking to the side as she asked the question. She arched one of her brown eyebrows, unintentionally causing it to thicken and sprout coarse black hairs.

“No?” Kimma asked quizzically. How in the nine layers of hell did Erin not realize what was happening? This TransFun serum was really good! She stared on in shock as Erin nodded happily, looking back down to her bowl to resume her canine consumption.

Then the brunette stopped, her nose twitching as she sniffed at the air. Her brown locks curled slightly as she picked up some incredibly wonderful smell, a smell that made her cock hard and her balls clench. But where could it be coming from?

As delectable as the soup was, it provided no such stimulation. And it couldn't possibly come from Kimma. That left Abby... Erin began to drool as she looked at her friend sloppily slurping the stew.

Her cock leaked a few droplets of pre-cum and she stared harder, her hips wriggling as she thrust into the air, imagining that she was spearing Abby's sopping wet cunt. It was a good image, and she—

If Kimma thought that she couldn't be more surprised by tonight's events, she was sorely mistaken. Erin looked just as lusty as Abby—if not more so! The girl was practically fucking the air, and the desire in her eyes was something that Kimma wasn't to keen on seeing reach fruition.

She swallowed nervously, wondering what would have happened to her if she'd drank a poodle potion. It would probably make her into a male dog too, letting her and Erin pound away at Abby... And as enticing as the offer was, it was a little extreme for her.

And it was certainly too extreme for Erin! Kimma watched as her friend slobbered into her bowl, the girl's nose and jaw beginning to stretch from her face into a pointed canine muzzle. She had to stop this!

“Hey!” Kimma shouted, pointing at Erin. “Finish your food first, you bad dog!” It was a stretch, but if Erin really had been loaded with a set of canine instincts, then this was the best way to get her under control.

Erin blinked and shook her head as common sense returned to her. She had to finish her soup, what was she thinking? She too plunged her head into the stew, her tongue extending from her mouth to better slurp the meat into her growing muzzle.

Abby, on the other hand, was whimpering with need, her toes clenching as they bulged out; her soles growing plump and lush paw pads. She was into bad dogs—or rather, she was into bad dogs forcing themselves into her. She kicked her sandals free of her paws as she continued to eat, the chair no longer feeling comfortable.

The blond growled lowly under her breath, then moved to squatting on her chair, letting loose a breath of relief. She smiled happily at the comfier feeling, a proper canine posture for a proper bitch. And she did ever so want to be Erin's bitch...

“Hey! No fucking!”

Kimma's voice intruded on Abby's thoughts, and she drooped her long ears to the sides of her head, feeling a thick coat of fur whelm over them. What? She was a bad girl? No, Abby wanted to be a good girl!

Abby plunged her face back into her bowl once more, her cheeks heating up with both a blush and the growth of fur alike. She whimpered and felt her spine lengthen from her backside, as if to form a tail so she could droop it abashedly.

The instigator and now wayward guardian Kimma nodded to herself, a nervous smile on her face. She just needed to somehow bide her time until they were both dogs. Dogs weren't that hard to command, right? She would just somehow get her friends into different rooms and lock them up; that would solve things.

Of course, Kimma had never had a dog—or even trained one. The closest she'd been to training a canine was watching the Air Bud movies, so she could be forgiven in thinking that all dogs were as tame.

So while it would come as no surprise to anyone with experience in training dogs, it came as a great shock to Kimma as Erin pounced her way to Abby, covering the girl in long and slobbery kisses.

Kimma froze in shock, a confused “Wha” escaping her mouth as the two girls' faces grew thick coats of curly fur.

Erin didn't care if she was a bad dog; she wanted to fuck Abby too badly! Her cock was so hard, she needed to slam in into Abby's lusty cunt and stir her to heights of pleasure she'd never experienced!

As if it was echoing her stiff cock, her spine extended from her body, a thick and black poof of for marking the tip of her new tail. She wagged it frantically, trying to spread as much of her scent through the air to convince Abby to be hers.

Abby tried to lean away from the kisses, her tail pert as she whimpered. She didn't want to be a bad girl, but what could possibly be bad about being with Erin? Her mind began to cloud over, and before the girl knew what she was doing, she leaped from the chair to the floor, her ass held high as she knelt down on all fours. The girl whined loudly, her tail moving to the left to expose her sopping wet pussy to Erin.

The dark poodle needed no further invitation, jumping upon Abby's backside and hilting herself within her friend on the first try. It was good; too good! Her tongue lolled from her mouth as Abby's snatch gripped her cock in a tight and warm suck, rewarding her for every thrust.

The sound of wet fucking filled the air as the girls reverted from a bipedal to a quadrupedal stance, and they were soon loudly panting, tails waggling madly as fur covered the rest of their skin.

Kimma watched and heard all of this with shock and disgust alike, her eyes wide with horror. She'd never meant for tonight to end like this! What the hell was going on, why were her friends having sex now; didn't she tell them not to?

“B-bad dogs! No fucking, please stop!” Kimma tried, her face as red as a tomato.

The two poodles didn't heed the strange sounds coming from the human's mouth. They were a pair of lusty animals, and right now all they wanted to do was fuck and fuck and fuck some more!

Erin pounded at Abby's pussy, driving herself harder and harder into her bitch. She wanted—needed the girl to howl with release, to clench around her cock and loudly declare herself Erin's mate!

As though she was reading Erin's mind, Abby howled, her folds gripping Erin's thick member as a wave of climax rushed over her, making her spill over Erin's member. She clenched her vaginal muscles tighter, eagerly awaiting Erin's release.

The white poodle didn't need to wait for long. Erin came with a loud howl a moment later, her cock inflating to a huge knot as she felt the undeniable ecstasy of release. She spurted wave after wave of cum into her friend's pussy, marking her as her bitch forever.

Spent, the two dogs began to shrink into their clothing, diminishing to a proper size for a pair of horny dogs. Kimma watched all of this with growing shock, shakily standing to pick up the dogs and get them in their own beds.

At least, that was the plan—but the two animals were connected by Erin's cock. Kimma squeaked with disgust as she felt some of their fluids spill onto her arm, and she settled for placing them on Erin's bed.

With that, Kimma took three showers and flopped into her own bed, still feeling unclean despite the fact that her arms were raw and red from the scrubbing. She could only hope that her friends would forgive her come morning.

In that, she was to be sorely disappointed. Erin and Abby woke up in each other's arms the next morning, their eyes widening as they remembered what they'd done the last night. Soundless screams escaped their lips and the two hurriedly looked away from one another, unable to make eye contact.

It was Abby who broke the silence with two simple words. “That. Bitch.” She quivered as the second word left her lips, still remembering how much she wanted to be a lusty and drooling dog.

Erin, normally the rational one, found herself agreeing with her friend. “So... What do we do now? We can't well give her that TransFun we'd planned; that would be rewarding bad behavior.”

“It would be.” Abby nodded with agreement. “Unless if we were to give her a taste of her own medicine. What if we had that cunt grow a cock?”

Erin's eyes widened and she mouthed wordlessly. Abby was normally so innocent; this must have been the result of some of the leftover hormones from last night! And speaking of hormones, she found herself all too willing to agree to the idea.

“Only if she fucks us.” Erin said slowly, a grin spreading on her face. Last night was good as a man, but she wanted—needed—to be a female animal; to be claimed by a strong and furry male!

“So... We're doing this for sure, right?” Abby's eyes twinkled dangerously, and her smile only widened as she saw a similar sparkle in Erin's eyes.

“Of course. I have needs too, you know.”

And so it was that the two found themselves with a set of TransFun serums and a breakfast to make. Thankfully Kimma liked to sleep in, even after what had happened last night.

Still, the girls didn't want to take any chances, making a quick cereal for breakfast.

“Mine first.” Abby smiled, pouring her special serum into Kimma's meal. She didn't want to have second thoughts about this, and so she found herself emptying a tiger serum into the girl's bowl.

It was just in time too, as Kimma tiredly made her way downstairs, clad in only a t-shirt. The girl rubbed at her eyes tiredly, hoping that Abby and Erin didn't remember last night. To her surprise, they were both smiling happily at her.

Kimma found the sparks of hope blooming in her chest, and she looked at her friends with a smile. “H-hey guys. I hope you liked dinner last night.”

It was an indelicate statement that would have undoubtedly send Abby and Erin over the edge had they remembered. But the two girls simply smiled back at their friend, a twinkle in their eyes as they looked at the brunette.

“Oh, we loved it! We can't really remember what happened after, but we wanted to reward you with a bowl of your favorite Captain Crunch!” Erin gave Kimma an Oscar-worthy smile, sliding the bowl over to her.

“Aw, thanks guys!” Kimma breathed a sigh of relief. She grinned and took a spoonful of the cereal into her mouth, crunching on it happily. “Mn, it's fresh, too.” She moaned with delight.

Abby watched with interest as her friend dug into the cereal, her cheeks beginning to grow a thick coat of white fur. Kimma gave no sign of noticing, instead stretching her back and yawning as her body began to bulk up, growing thick and masculine muscle.

Satisfied, Abby turned to the counter top to take her own serum, quaffing the vial in a hurry. The leftover hormones coursing through her body demanded she be mated with Kimma. Abby so desperately needed a thick and tiger-y shaft to fill her pussy, to rake her folds with its engorged spines.

Erin took a step back from her friend as her friend transformed, watching with interest. This time, revenge certainly was a dish best served cold! The thought gave her an idea of how to dose Kimma with her own serum, and Erin found herself eagerly awaiting her own revenge.

But for now, this was all Abby's dance. The blond pushed her hair back and sat on the counter, spreading her legs as she started to get hornier and hornier. These serums worked wonders on her! She moaned lustily and fixed her gaze upon Kimma. “See something you like?”

Her tailbone started to lengthen as she spoke, and the girl slipped her shorts off to reveal she was wearing nothing underneath them. Free to grow, her tail snaked out, growing thick orange-and-black striped fur along itself.

Kimma opened her mouth to ask why Abby was acting so weird, only for a cramping sensation to assault her pussy. She whimpered in sensation as she slowly began to develop a penis, her pussy surrounding it and becoming a thick and furry sheath.

Then she had her first erection, a sensation entirely brought on by the sight of Abby's wet pussy. Kimma whimpered happily as her cock bulged, thick and keratinized spines emerging from its length. She stroked at it gently, a coo escaping her whiskered lips.

“You want to be a good kitty?” Abby asked, gently intruding on Kimma's thoughts.

The tiger-to-be nodded. “Nnhh... Yes...” Kimma moaned, lapping up the remnants of milk from her bowl with a tongue which grew coarser and furrier by the second. Finished with her meal, she whimpered happily and padded up to Abby.

“Then what are you waiting for?” Abby breathed, her tail swaying behind herself even as her pussy began to puff, plumping to a rich and feline form.

Kimma responded with a low and husky growl, eagerly plunging her head into her friend's folds, lapping eagerly away at her sweet nectar.

Abby moaned loudly at the sensation of her friend's rough tongue, stimulating her feline form to leak more and more onto Kimma's furry face. She whimpered with delight, her ears drawing to the top of her head as Kimma continued her indelicate ministrations.

“S-such a good kitty!” Abby's voice seemed impossibly loud to her own ears, and she found her hands wandering to the top of her head, feeling her ears as they rounded and grew lush fur.

That was the breaking point for Abby, and she pushed Kimma back, relishing the confused mewl that escaped her friend's lips. Abby dropped to all fours, stalking her friend like a predator. “I can't possibly let myself be the only one to be prrleasurred.” She purred happily, rolling to her back and slipping beneath Kimma to lap at her cock.

Kimma's eyes widened dramatically and she filled the air with a low and rumbling moan, thick muscles toning her chest even more as fur grew to cover her form. She dropped to all fours as well, needing to lick Abby's pussy, to tend to it in thanks for Abby's own delicate tongue-play.

Abby whimpered with delight, a loud gasp escaping her mouth as her nose and jaw stretched away from her face into a muzzle. The tip of her nose flattened out as her muzzle grew, and Abby trembled with delight at the feeling of having a muzzle once more. She might actually be addicted to TransFun...

The thought sent a rush of adrenaline through her body, and Abby took Kimma's feline cock into her lips once more, delicately sucking at its spined exterior. She couldn't wait for Kimma to bury it within her folds; she was already dripping with the thought of her friend entering herself!

Kimma was similarly aroused, low rumbles escaping her throat as she sent her long tongue questing along Abby's thick folds, savoring the flavor of her lusty honey. Kimma loved this; loved every contented sound her mate was making beneath her!

The only thing Kimma didn't love about this was how her shoulders and hips were beginning to cramp from this pose. She wanted to be able to service Abby without any discomfort, wanted—

A loud set of pops heralded her salvation, and Kimma found her face thrust deeply within Abby's folds, her lips pressed firmly against her pussy's pussy. The tiger rumbled with delight, pulling back so she could bathe Abby with licks once more. But much to her surprise, the transformation had other ideas.

Her lips remained where they were, even though Kimma's head had moved. It took her lust-afflicted brain a second to realize that she now had a muzzle, and she promptly purred with delight, nuzzling her furry whiskers against Abby's crotch.

“Srrruch a grrrood kitterrrr!” Abby growled, her vocal chords twisting and changing even as she felt pleasure course its way all along her body. She wanted the tingling electricity of ecstasy to fill her form, to make her expand with change!

In that she wasn't let down, her thin frame growing larger and larger with every lick of Kimma's. Lithe feline muscles covered her arms and legs, and her chest heaved with every breath the satisfied girl took.

She moaned with pleasure, flexing her fingers as they bulged with change; her nails lengthening to form claws. She danced these along her tank top, tearing it and her bra free at the same time.

Of course she also cut herself in the process, but that hardly mattered to the girl. Her changes were rendering the scratches moot as well, her hide thickening and fur covering the scratches as though the cuts had never been there in the first place.

Kimma rumbled with approval as her mate's thighs thickened, growing lush fur that tickled Kimma's muzzle as she nuzzled deeper into Abby's groin. The girl growled contentedly, her tail sweeping from side to side with pleasure as she felt her own body grow a matching coat of fur.

A matching coat of fur! She was going to be Abby's mate; Abby's match! The tiger growled lowly, wishing so desperately that she could penetrate Abby's pussy instead of her mouth.

To her surprise and delight, Abby replied with a contented growl of her own, the tigress popping Kimma's cock from her mouth and rolling to all fours, waggling her hips enticingly.

Kimma's licking had been so good, so perfect! And if licks alone had been this good, Abby could hardly imagine how good the real deal would be. Abby felt her palms and soles plum up with lush and rich pads as she quavered with pleasure, sheer sensation overwhelming her other senses.

Kimma growled happily and hopped behind her tigress, her cock pressing at Abby's wet entrance. Then, with a play of her hips and a growl of pleasure, she plunged herself into Abby, eliciting a yowl from the girl.

Abby was overcome with pain and pleasure alike, feeling the thick barbs along Kimma's cock raking her folds, and she felt herself drip with honey, sweet nectar making the passage of Kimma's cock even easier for the tiger.

Of course, Kimma responded to this with a growl of gusto, redoubling her efforts to thrust deep within the tigress. She loved this! It was so insanely pleasurable; she couldn't believe how good it was to fuck Abby!

The tiger growled under her breath, beaming as Abby bucked beneath her, rolling her hips back against Kimma's. Abby was as talented a lover as she was a passionate one, and she was making this more than heavenly.

Abby felt the same about Kimma, rumbling purrs contentedly slipping from her throat as Kimma continued to thrust into her; to please her. She loved every minute of this, grunting as her body expanded from its normal size to that of a massive tigress.

She could feel the same from Kimma; feel her tiger's weight growing heavier and heavier on her back. A small part of Abby's brain curiously wondered what would happen to Kimma's shirt, surely stretched to the point of breaking.

Kimma was wondering the same, grunting with discomfort at how tight the shirt was against her body; how it was pressing down against her furry body so tightly that she could barely bear it.

Then, with a loud tearing of threads, the seams of her shirt finally split. It was the sweetest relief to the tiger, and she groaned happily with delight. The feeling of relieved pressure swept through her body, and she grunted as a tail squirted its way from her backside, sprouting to its full length in less than a second. She put it to good use, curling it around Abby's tail and making her tigress yowl with pleasure.

Abby groaned, so glad that she's taken the first round with Kimma. Her body was still so lusty from the night before, and this was the sweetest relief. She whimpered happily, letting her thick tail sweep from side to side, held tightly by Kimma's own.

Sure, she felt a little bit bad for taking advantage of her friend like this—but this was miles apart from what Kimma had done to them last night! She whimpered happily and wriggled her backside against Kimma, spurring their changes to completion.

Both Abby and Kimma grunted as their arms and legs expanded, bulky muscle covering their limbs, making them lithe, powerful, and above all, virile. Fully transformed, the pair of tigers howled as simultaneous orgasms broke across them.

Spent, the two fell to the ground, tiredly having a quick catnap as they regressed to human form. They didn't so much as notice the change back, and Abby found herself drifting awake to find Erin smirking down at her.

“Have fun?” She whispered, extending a hand to her friend.

“You've no idea.” Abby gratefully accepted the help, grunting as she stood up. Her hips were sorer than she could ever remember, and she had to wobble her way back to her room.

Meanwhile, Erin took the time to prepare her own revenge, spiking a pair of beers with bunny serum. Tempting as it had been to make Kimma into a dog as fitting payback, Erin always had been curious to see for herself what it meant to 'go at it like rabbits'.

Thankfully Kimma was a sound sleeper—even more so after the rough sex she'd just had. She slept through Abby getting dressed and Erin preparing her drinks, only waking up when Erin loudly cleared her throat.

“Nnh... What.. What happened?” Kimma asked, her first words as a human.

“Hm? I think you were sleeping.” Erin chuckled. “Having one hell of a dream too.”

“Mn? Oh, makes sense.” Kimma yawned, blushing quietly. “Thirsty.” She moaned.

Erin seized her opportunity, extending a glass of TransFun-dosed beer to her addled friend. “Well then, I'd say you could use a drink!”

Kimma took it gratefully, sipping the cool contents only for her eyes to widen a moment later. “Is this beer?” She asked curiously.

“Yes...” Erin said unsuredly, wondering if she'd acted too rashly.

“Good.” Kimma said, downing it and yawning. “'Mn get clothes on.” She moaned tiredly, stretching herself out as she walked into her room.

Erin watched her go with a smile on her face, only to yelp as Abby glared at her. “What?” Erin asked, her heart hammering. Despite not being a tigress any more, Abby had maintained an impressively intimidating look.

“That wasn't exactly subtle.” Abby growled lowly.

“Y-yeah? Well, it's my prank! I choose how I run it!” Erin gulped nervously, looking to her own TransFun-dosed beer. “Besides that, it worked, didn't it?”

Abby nodded slowly, then shook her head out, clearing the leftover tigress from her head. “Mhmm. Sorry about that.” She scratched the back of her neck idly. “I think there was still some jungle cat in me.”

“I'll say!” Erin laughed, hugging her friend with relief. It was the first time they'd gotten this close since being dogs, and the two girls felt their cheeks redden at the proximity.

“You'll say what?” Kimma's voice intruded on their moment.

Erin and Abby spun to find Kimma in a pair of jogging shorts and another unkempt t-shirt—and also a pair of long and fluffy white bunny ears. “Hey, anyone seen my shirt?” Kimma continued, yawning loudly. As she yawned her ears twitched tiredly, and her friend shad to hold back their laughter.

“Um... I think it's in the kitchen? I don't know what happened to it, it's like a dog got at it or something.” Erin said quickly, a lie she'd prepared when Kimma was balls-deep in Abby.

“Oh. Oh!” Kimma blushed. Her spare sleeping shirt must have gotten damaged last night somehow; how could she forget? She hurriedly ran to the kitchen to pick up her shirt.

Erin followed her with a smile, drinking in the sight of Kimma bending over and exposing a wriggling and fluffy cotton tail. Erin's heart started to race, and she licked her lips with anticipation.

And she wasn't the only one to feel aroused. Kimma felt her groin tingle as her folds fused, her clit lengthening into a cock. She moaned loudly and began to touch herself, a rabbit's libido establishing itself in her loins.

Kimma trembled with sensation, dropping the shirt as she began to stroke at herself with both hands, rubbing them all along her shaft. It was an oddly familiar sensation, and Kimma moaned happily as she started to remember her dream, of burying her cock within her mate.

It was at this point that Erin realized she'd forgotten to take her own dose of TransFun, and she hurriedly drank from her own beer. She had to transform too; it wouldn't be much fun if there was a tiny bunny trying to spear her pussy!

The thought sent a rush of heat to her loins, and Erin blushed as thick whiskers sprouted from her cheeks, lengthening to form a proper set of rabbit's whiskers. She squeaked gently as she pet them, feeling the soft hairs beneath her fingers.

The sound was enough to remind Kimma that there were others in the house, and her head snapped up to stare at Erin with wide eyes. However, instead of feeling embarrassed for feeling herself up, she only found an immense attraction blooming in her heart.

How had she not seen it before? Erin was the one! Erin was her mate! Erin was her fucktoy, her object of pleasure who she'd plunge herself into and fuck for hours and hours and hours and...

As Kimma's thoughts devolved into those of a lust-drunk rabbit, her eyes began to glaze over. Abby recognized that look, having sported it herself twice within the past day and a half.

She hurriedly pounced on Kimma, restraining the girl before she could leap at Erin. After all, Erin was barely changed!

Erin smiled thankfully at Abby, revealing a pair of large buck teeth. She was such a good friend, but... But she was nothing like Kimma! Kimma was so sexy like that, wriggling at Abby's hands, trying to spear Erin's bunny cunny... Erin needed Kimma to claim her!

Abby yelped in surprise as Erin bounded forward, and before she could restrain her friend the girl had pressed her lips hard against Kimma's.

Pleasure filled the pair of transforming girls, and they moaned into each other's mouths as they felt an insane rush of attraction to one another. Kimma especially felt naughty, her hips wriggling as she started to buck within her pants, a lusty moan escaping her lips.

Erin blushed at the sound, her own ears beginning to lengthen and draw up her head. As they transformed they sprouted lush brown fur, and Erin blushed as the fur started to sweep across her face.

Unfortunately for the would-be-lovers, they soon ran into a new problem: Kimma started to shrink, her body dwindling by the second. She looked up with wide eyes at Erin as she dipped within the collar of her voluminous clothing, finding herself unable to satisfy her mate.

The sight tugged at Erin's heartstrings as much as it did her lust, and she scrambled free of Abby's grasp, grabbing her shrinking friend with one hand and tugging down her skirt with the other. Then she shoved Kimma's face into her cunt, moaning loudly as the bunny instinctively began to lap at her folds.

“Yes, yes!” Erin moaned lustily, her legs thumping as she rolled onto her back, her eyes glazing over with pleasure. Kimma was lapping away at her like there was a carrot buried within her pussy, and Erin loved every minute of it!

Then her own body began to shrink, and Erin squirmed with delight as her hold on Kimma became a lusty embrace. She squirmed and squeaked with delight, feeling her shirt billow over herself like it was a thick blanket. This was way better than when she was a poodle!

Before she knew what she was doing, Erin was on all fours, wriggling around to reveal her backside to her mate. Kimma naturally seized her opportunity, pounding away at Erin's pussy.

Abby chuckled at the sight of her friends, lost to lust. She pulled up a chair and sat down, enjoying the view. Revenge, served cold for a dish served hot. It was almost poetic, and the girl laughed again, fanning at herself.

Despite the fact that she was human, she was enjoying this as much as if she was a rabbit. The girl saw a beer in her peripheral vision and gratefully drank deep of its cool contents, feeling a nice rush of relief spread through her body.

Both Erin's and Kimma's faces were pushing out into small and stubby bunny muzzles, and they squeaked contentedly as their eyes slid to the sides of their head in a perfect prey-vision.

Abby watched this with growing interest, her right leg beginning to thump at the ground as her arousal compounded, a tremendous lust filling her body. The girl kept staring in delight, her hands brushing between her legs as her right leg became that of a rabbit.

Her left leg soon followed suit, her hips widening to accommodate the rabbit's stance which she was using to sit on her chair, huffing quietly with pleasure at the sight of Erin and Kimma rounding out into rabbits, of them going at it like rabbits!

Her hands grew soft and lush paw pads, velvety flesh coming in along her palms. The girl used these to sate her growing lust, but it was nowhere near enough to leave her content! She wanted—needed more!

The girl's nose shrank on her face, dwindling to that of a bunny. She sniffed at the air, drinking deep of her friends' lust, of the rich scent of their fucking! She needed to be a part of their lovemaking, needed to shove her face in Erin's folds as Kimma smalled into her from behind!

Whiskers sprouted along her face, and the girl found herself shrinking in her clothes, able to hop free of their fabric confines—and hop to join her friends! She bounded out towards them with a smile on her furry cheeks, eager to join in on the fun.

The white and brown rabbit turned in surprise at the sight of Abby transforming into a beautiful black rabbit, but that surprise lasted for only a moment, soon giving birth to renewed lust.

Indeed, as a fluffy tail burst from Abby's backside, Kimma bounded over to her to fuck her too, to make her feel as contented as Erin was! Naturally Erin protested at this—though only for a moment, as she realized Abby was more than eager to taste her dripping folds.

The trio continued in every position imaginable and then some, using their bunny bodies to the fullest and cumming more times than they could count. It was as pleasurable as it was tiring, and the girls loved every second of it.

A few hours later, the three girls transformed back in a tangled and sticky heap of limbs on the ground. Kimma started to recall how her morning—and then her afternoon—had been spent, and she groaned tiredly.

“So... No more TransFun?” She asked. “We're not going to do this again to each other? Prank war: truce?”

Abby and Erin looked at each other mischievously. In truth, today was the most fun they'd had in their lives. And last night wasn't bad, either! And that threesome... Their hearts pounded in unison with the thought of having another round as a trio.

“Of course not.” Abby cooed, trailing her fingers along Kimma's chest. She looked up to Erin and winked conspiratorially.

“We promise.” Erin agreed, hugging Kimma's naked body a little closer to her own, her fingers crossed.
