Finally, it was weekend. When Slick arrived home after work, he looked almost haggard. After only a few hours spent relaxing and having a good meal - and of course, the all-important shower, almost a ritual to wash the work off his body - he looked about ten years younger. Felt like it, too. Now, it was time to have _fun,_at least until the next workweek reared its ugly head. The rabbit had bought some new games just the other day, and there was no better way to enjoy those than with a friend.

He called up Luka, a long-time friend. He left work a few hours later than Slick, and still sounded exhausted when he picked up the phone, but perked up in no time flat when he heard Slick's plan: a whole night indoors, gaming, with takeout food. And of course, being that the two were occasional lovers, perhaps some loving too. Either way, he didn't hesitate to say yes before hopping in the shower and getting ready for their "date" - all the exhaustion of working all week gone with the water.

The evening went as planned, after he arrived. Of course, if nothing else had happened, there wouldn't be a story being told. Indeed, eventually things took a turn.

Slick and Luka had been hanging out for a while when they discovered it. An old can of Pussy-branded energy drink that'd rolled under the rabbit's couch at some point. Luka's controller fell and slid just under the seating, and when he stuck his hand in to fish it out, he caught not only the controller but the can, to his amusement.

It didn't even seem to be the actual brand, but rather a cheap knockoff, and Slick couldn't quite remember when he'd actually gotten it, and on top of that, it was dusty enough to set the both of them off sneezing when Luka wiped it clean. At first, he simply sat it aside as the two continued gaming and talking, simply enjoying themselves for the weekend.

"I didn't know you liked pussy that much," Luka eventually quipped.

"Har. I bet you're the first person to ever make that joke," Slick shot back, feigning a frown. Not that anything could really get him down when hanging out with a friend after work.

But every time either the rabbit or the German shepherd happened to see it again, it somehow got more amusing, inspiring all kinds of more or less juvenile jokes about pussies between the two, until they were both practically doubled over laughing, perhaps more at how bad the jokes were rather than the jokes themselves. Maybe some part of it was the relief the weekend always brought with it, too..

"O-okay, okay. So, how about, whoever loses this next match has to drink it?" Luka suggested, his voice a little wheezy from their previous exchange.

"God, no, it's probably radioactive by now. It might even be from the previous_tenant," Slick replied. The previous resident of his apartment _had left the couch there, though more because he hadn't wanted to deal with carrying it out. "And there's no expiration date at all!"

"I didn't know you were that gay," Luca giggled, his tail lashing back and forth. "There's nothing wrong with some older pussy. You cradle robber."

They were right back to laughing about it, without even knowing what exactly they found so funny. It was just one of those things that only got funnier with repetition. Eventually, Slick decided to search the internet for if energy drinks _could_even turn toxic when the dog kept insisting that one of them was to drink it.

The answer to that seemed to be no. It might go flat, and _eventually_undrinkable, but as long as the can wasn't visibly corroded or pierced, it should at least be safe.

"Bro, just drink it," Luka giggled. "You know you're gonna lose anyway."

Well, _those_were fighting words, and the drink seemed like it wouldn't kill them, so Slick grabbed his controller, got in the game, and...

...promptly lost.

"Oh, come on!" he exclaimed. "How long have you been practicing this?"

"Well, I've played it once or twice before, maybe," Luka answered. He'd had _this_game for a while and could still remember all the combos that the rabbit hadn't even read up on yet, so it was an easy win. Not that he was about to point that out and be forced to drink the ancient energy drink. "You lost, though, so fair's fair. Drink up. Or should I say... eat out?"

His grin was wide, toothy, and Slick might've also used the term "shit-eating", but he was right, regardless of any technicalities. Well, that, and the dog was just too charming to really be angry at, with how his tail threatened to knock over their bowl of snacks as he got more and more excited.

"Fine," Slick sighed. He ran some water over the can of "pussy" to wash the rest of the dust off. It didn't look corroded or in any way unsafe, so he opened it. No sound of escaping carbonation, great. Totally flat. He lowered his nose towards the can's mouth and sniffed. It... didn't really smell like much of anything. The slightest tang, that he felt like could be the smell of a very excited woman, but maybe a little more sugary.

"Drink! Drink! Drink!" Luka chanted, urging his friend on.

With a roll of his eyes, Slick brought the can to his lips and tilted the contents into his mouth. It tasted almost... salty. There was some sugar, and a bit of a faint citrus tang, but other than that, nothing much. Certainly nothing bad. If he closed his eyes he could almost imagine himself eating out some attractive woman who was gushing like crazy, and so the drink went down easily.

"Well, that wasn't so bad," he said. "Just... kinda old. I prefer them closer to my own age-" he grinned, and then went quiet as he felt a sudden flush of heat in his stomach. It didn't feel unpleasant, but he still doubled over in surprise as that warmth - now tinging as it radiated from his belly and out towards his groin and chest - grew and grew, until he had to lay down, panting.

This wasn't what energy drinks were supposed to do at all. Luka looked at him with sudden concern.

"Think I should call an ambulance?" he asked, with that concerned canine whine to his voice.

"Nnf, no, I don't think it's... actually it feels kinda good," Slick groaned in response.

When the rabbit suddenly clutched at his chest, Luka initially nearly panicked, thinking he was having a heart attack - but no, soon Slick was moaning, and not as much clutching as he was massaging his chest... which was swelling. The dog's mouth gaped open as he watched his friend grow undeniable breasts. _Sizable_ones. His nipples swelled too into something much more feminine, immediately stiff and perky as his chest grew.

"Jeez, what's... what's happening," the rabbit groaned. "It feels... am I growing..."

Luka couldn't quite find his voice. The display was absolutely transfixing, and those hefty boobs bounced so enticingly as Slick squirmed and thrashed. Enough so that he could feel his sheath getting awful tight watching it. Then, Slick gave another moan, a far more high-pitched one this time. Even his voice was changing, much of his masculine definition seemingly melting away.

One absurd thought came to Luka's mind. If he was to accept that the "energy drink" was doing this, shouldn't Slick also be growing a...

He glanced between his friend's legs, only to realize that his sheath seemed to be deflating and shrinking. He was growing a pussy, wasn't he? Yes, he was._Luka _stared with growing lust drowning out his concerns, reaching to caress between Slick's legs, feeling his genitals shift and change. It felt immensely erotic.

Slick himself, meanwhile, was paralyzed by a deluge of pleasurable sensations. His tits - which he still could barely believe he had, even though he was frenziedly rubbing and massaging them - felt so heavy and looked so incredibly sexy. Each time he squeezed them, he moaned reflexively as a jolt of pleasure shot through him, sounding more like a girl each time. That wasn't all, either. He could feel a sense of heat between his legs, too, accompanied by an odd feeling of emptiness and a sensation of his insides coiling up.

"W-wh-" he stuttered, feeling Luka's fingers press against that increasingly heated spot. He couldn't see past his enormous breasts but on some level he knew exactly_what was happening, although he couldn't _believe it before he felt the dog's digits suddenly slip into him. He clenched around them, crying out with shameless lust as a gush of feminine wetness spilled from his body the moment his new slit opened up, already excited, puffy, and swollen.

"God, that's hot as fuck," Luka huffed, next to him, pushing his fingers deeper into his friend's body and marvelling at just how wet and tight he felt. By now he was fully hard too, his canine shaft rock-hard and ready to take advantage of the situation.

Normally, he wouldn't have, but there was just something about Slick's scent that was getting to him in a big way. Some indescribable tangy fragrance that made his heart pound twice as fast, made his cock throb, and more than anything, was drowning his mind in fantasies of just mounting his helpless, sexy friend. Like he - or she - was going into... oh, damn.

"Mrh- I need you," Slick groaned. She was feeling it too, only a hundred times more intense than her scent could ever signal. The feeling of emptiness only grew and grew, and when she managed to open her tear-filled eyes, her gaze landed directly on Luka's cock. She instantly knew that she needed it, probably more than she'd ever needed anything before. Like it was the only thing that could soothe the infuriating, burning need inside her. All thoughts of consequences were gone as her mind basically went blank with roaring desire.

Slick spread her legs wide. It felt like the right thing to do, somehow. To her delight, Luka immediately scrambled onto the couch and positioned himself between her thighs. He was only barely more in control than Slick, and certainly not enough so to resist his friend's primal display of lust. Not with her scent filling his nostrils and mind, consuming any attempt at rational thought. He hadn't even settled before he was already humping wildly, the primitive part of his canine brain in full control and only aware that there was a beautiful, needy bitch beneath him, ready to be bred.

A few more desperate thrusts later, he sunk into Slick's new, soaked pussy. The both of them groaned in unison in the throes of helpless passion and lust, Slick at the _beautiful_sensation of a thick, firm shaft finally scratching that itch inside her, and Luka in turn at just how tightly Slick's inner muscles clenched around him, almost burning hot as they massaged his cock eagerly.

That wasn't the end of the changes, though Luka could only barely consider what was happening when he saw a second set of curvy breasts begin to swell beneath Slick's first, bouncing pair. He saw something white begin to trickle from the first as his feverish thrusts rocked her changing body back and forth.

Something inside him told him to drink it. Another part screamed that it was a bad idea, but was entirely drowned out by how good his cock was feeling. He, lost in the moment, leaned down and wrapped his lips around one of Slick's inviting, swollen nipples, and began to suckle. The flavor was... comforting, somehow. Sweet, warm, and incredibly erotic, quickly filling his mouth even as Slick thrashed in mindless, squealing pleasure at the sensation in turn. He swallowed eagerly, settling into a lusty rhythm, even reaching to actively _milk_his friend for more, switching from one breast to the other to relieve the pressure she surely was feeling.

As he did, his cock seemed to grow even bigger and harder inside Slick's tight, clutching tunnel. Massively bigger, as if every drop of sweet milk went right into his shaft. Thinking, of course, grew even harder with his erection drawing more blood from his already weakened mind. The dog was barely aware at all that he'd gotten so big that his sheer girth was forcing Slick's hips to grow wider. Luckily, whatever he'd drunk had left him soft and malleable enough that it didn't hurt in the slightest, even as his bones creaked.

It wasn't only his cock that was growing. With every gulp, his balls grew too, and he didn't even notice them growing big enough to rest against the sofa as he rutted. The only thing he knew was that he needed to cum, and it wasn't as if his newly transformed friend was going to protest. With a triumphant, lusty howl, he thrust inside Slick and came like a firehose. His eyes rolled back in their sockets with how massive that climax was. There was some faint realization that it wasn't normal, feeling the backwash of cum soak his sheath, but it felt far too good to care. It went on and on, the dog pumping out what felt like gallons of his hot, sticky seed while drooling onto Slick's massive tits.

Slick, for her part, was somewhere very far away. She was cumming, alright - her body was fiercely_milking Luka's twitching, throbbing cock - but it was so intense that she was on the verge of going unconscious, the pressure and purposeful jets of cum erupting into her new womb to soothe her heat robbing her of all control. The sheer _satisfaction of her body receiving what it craved was enough to make her feel like she was floating, everything but those beautiful orgasmic spasms muted and dull to her sense. Her passionate and shameless screams and squeals joy echoed somewhere far in the distance, and her own wetness gushing and squirting - coating the sofa with her feminine juices - was barely noticeable at all. Nor was the fact that she might get pregnant. She didn't even know, or care, if she could.

Finally, though, even their transformation-fuelled lust died down. Luka slumped down on top of Slick, using her humongous breasts as a makeshift pillow, while the latter was still trembling with afterglow.

"Jeez... what... w-hat even happened?" she finally managed to moan, slowly descending back to earth from the carnal, sexual heaven she'd spent what felt like minutes in. Suddenly, she was rather self-aware of how it felt like she was laying in a warm puddle of their mixed fluids, and when she tried to move, her four breasts all wobbled on her chest.

She couldn't quite deny that they - and she, and her thrumming pussy - all felt fantastic, but the fact that she was apparently a woman, and a very busty one at that, was cause for some concern. She squirmed out from underneath Luka, shivering when his knotted shaft popped free. The dog was nearly passed out, just like she had been, and the couch was soaked in his cum. His sack also looked so big that Slick had to imagine Luka would struggle to walk, at least at any decent speed.

Then again, she was rather top-heavy herself. Not to an impossible degree, but she could already feel the strain on her back. That would start hurting eventually.

Slick left a trail of cum behind herself as she walked. Just how much had Luka pumped into her, and was there a risk getting preg-

Ngh. Her groin was starting to feel warm again. How much more could she possibly transform? Slick rushed back to Luka to wake him up, only to be struck by a heavy scent in the air just like his friend had been, earlier. Why had she never noticed just how manly the dog smelled? There was a beautiful muskiness to his scent, a potency that only grew with the way it mingled with the smell of sex already lingering in the air.

No, no, no. Get a hold of yourself. We need to go and... and...

An almost electrifying jolt from her clit made Slick gasp, and she inhaled a good lungful of her friend's scent. Immediately her mind grew cloudier again, a dazed sensation asserting itself. The worries about their apparently ongoing changes seemed a lot more distant all of a sudden, though not so much that Slick was under its spell yet. She would be if she didn't put some distance between Luka and herself, though.

Yet just as she was about to wrest back control of her sluggish limbs, she noticed something strange. Despite the enormous bitch-breaker still bobbing where it jutted from Luka's crotch, his chest was looking softer and softer with each breath, as if his decent amount of muscle was melting away into fat. Not only softer; curvier and distinctly more alluring. Feminine. No doubt about it, Luka was going to grow tits too. The sight distracted Slick just enough that he took another breath, and immediately clutched at her head as the fogginess grew, along with that stiffness in her own crotch. Her hand dove down between her legs to feel what was happening, and she found her clit a little larger and harder than she'd have expected it to be. Not only that; her eager pussy was practically dripping again, with more than just Luka's cum.

In fact, wouldn't rubbing herself to a quick orgasm only make sense? After all, why not _enjoy_having a pussy while it lasted, her tainted reasoning went, trying to somehow rationalize how horny she was getting all over again.

Mm. Luka sure looks sexy too... poor thing probably needs another orgasm or two.

Her hands were already moving before her rational mind could react. She found herself fondling Luka's chest, kneading the soft mounds as if encouraging them to grow even bigger. Sure enough, the dog's nipples were growing damp with milk too. Whatever had been in the drink was clearly contagious, but that only made it more _fun,_didn't it? Slick giggled to herself. Luka moaned, stirred back into the waking world by intense pleasure.

That was when Slick got an idea that she didn't really think through; despite her best efforts, her thoughts felt like wading through molasses. Since her clit was already hard and swollen... Luka's cock had grown a lot after he drank her milk, hadn't it? So, if she did that too, she might get her cock back. Even if she kept the tits and pussy, which she almost hoped she would. They were just too fun to get rid of, even if it was unusual.

Sure enough, she wrapped her lips around Luka's teat. The dog protested only briefly before his whimpers turned into needy moans. It seemed his nipples were just as sensitive as Slick's own. He wasn't lactating a lot, at least not yet, so the rabbit had to work for it, suckling on her friend's nipple like a hungry puppy while massaging the burgeoning breast in slow, loving, kneading motions. Soon enough, her mouth was full of it. It tasted a little like the "energy drink" had, only sweeter and fuller somehow. Finally, Slick swallowed. Immediately, the transformations began again, rushing over her like a drug-fuelled high, and sure enough, her clit in particular throbbed. It began to swell - and Slick humped against Luka's leg as it did, enjoying the feeling - but there a was a strange twinge to it too. Like... a hard nub just above the clit, one that was also growing and swelling with arousal.

Oh. Slick giggled again. She was growing two cocks. Of course! But two cocks only meant twice the fun, didn't it? And combined with all her new attributes, it was like a hundred times the fun.

"We... nnf, we really shouldn't... do this," Luka panted, though his feeble attempts to dislodge his busty friend from his breasts was half-hearted at best. Token resistance because he couldn't quite accept that he desperately wanted whatever would happen next.

That _whatever,_for him, was the same tingly feeling of heat and dampness under his balls that Slick had felt, only his cock wasn't shrinking. It didn't take much thinking to guess what was happening, which was good, because Luka's thoughts were just as fuzzy and hard to pin down as Slick's. He was growing a pussy.

"I'm... I think I'm growing a pussy," he huffed, repeating that thought. Immediately, Slick's hand dove between his legs to feel it happen, and Luka let out a loud, stuttering moan at just how sensitive his new, oversexualized body had gotten. His breasts felt so wonderful, and more were growing in. Six bright, glowing spots of pleasure centered around his canine nipples.

"Mm-hm. Yes, you are," Slick giggled, her fingers dancing over the increasingly puffy mound under Luka's balls, probing against where she could feel the petals and entrance forming. "Just relax and enjoy it. Let it happen."

Sure enough, a moment later he felt what Slick had felt earlier that day. The wet and tingly sensation between his legs, which only lasted for a second or two before his new slit yawned open, and then a burning need somewhere in his lower belly. He was distracted by just how weird the rabbit's fingers sliding _into_him felt, but at the same time, his back arched with pleasure at how _good_it felt, too. He clenched with muscles he didn't even know he had, rocking back against Slick's probing digits. From the first moment, he was wet enough that Slick could effortlessly plunge four fingers into his clutching, dripping hole.

Just like Slick, he went into heat almost immediately, and before he knew it, he was breathlessly begging the rabbit to fuck him. It was only natural, even if his transformation was not. The words came instinctively, slurring as they left his trembling lips, but no matter how badly he needed it, Slick wasn't in a hurry.

After all, Luka wasn't exactly going anywhere. Oh, sure, she ached to rut the dog in turn, and to give him his own first experience of getting properly creampied, but she wanted to admire his changing body for just a little longer... and she could feel something still stirring in her own groin, too. A pair of exploratory fingers revealed that she was regrowing her balls, with a soft fuzzy sack slowly forming just between her cocks and sopping wet folds. Only this one seemed to be growing much bigger than her natural one had been, and she could feel four orbs in there, the size of ripe plums.

Somehow, the thought of being almost immobile because of how well-endowed she was only excited her further. Being a needy, always-horny sex object, for others to rut and ride was intoxicating, as much as it'd have been terrifying if Slick's mind hadn't been so altered, too. In fact, rather than worrying, she moaned as she felt her balls get big enough to touch the floor while she squatted, fingering Luka idly and watching his breasts grow until all six were the size of small melons.

When it finally seemed that no more changes were going to occur, Slick moved on top of her writhing, canine friend, with a lusty grin on her face. At first, she'd only been planning to fuck his new pussy, but she did have two cocks, and the both of them really seemed to want some attention, so it'd be a shame to leave his plump ass untouched, wouldn't it?

She rubbed some of the juices, milk, and cum onto her shafts and nudged one against Luka's drooling netherlips, and the other against his tight little pucker. It was absurd, in a way, but at that point, nothing really made sense anymore except their surging fuck-lust. Simply doing what their changed bodies were meant_to do, what they were practically _made for.

The two of them surrendered to the pleasure, fully. Everything just felt far too good to worry about, even though they'd struggle to continue on with everyday life in their obscenely oversexualized, transformed bodies. Lubricated by her constant stream of precum - not to mention Luka's dribbling juices - Slick had no issues penetrating both of his holes at once. The contrast was intoxicating; the full-shaft massage of his needy cunt combined with the tighter squeeze of his pucker. The rabbit and dog moaned in unison, their heaving breasts squishing together and only fuelling the fires of lust as milk smeared over them both.

Luka, in the heat of the moment, got another idea. Not something he would've considered doing normally, maybe. But the way his cock naturally reached between his breasts, he couldn't help but squeeze them all around it, letting Slick's thrusts rock his hips so he was effectively giving his massive cock a boobjob. And it looked so delicious where the pointed tip emerged between the uppermost pair, squirting copious amounts of watery precum over his chest and neck, almost reaching his muzzle.

It was so tantalizingly close. If he just craned his neck a little, he could... mmh._Sure enough, he could _easily reach his throbbing meat, and wrapped his lips around it hungrily, sucking on as much of that tasty, firm manhood as he could, moaning when his precum splattered all over his tongue. It tasted so _very_good, the sexual tang of it soaking into his tastebuds and setting his senses alight with excitement.

There was just something so incredibly hedonistic about it, shameless burning lust to worship every inch of his sexy new body, and Slick's too. Luka wanted to lose himself in the depths of nearly mindless pleasure and never leave them.

By now, Slick's back and hips were aching, but the blissful heat and wetness of Luka's body kept her going. It was almost too much - no, it was too much. It was like the dog's changed body was sucking on her, so desperately eager to receive her cum in both of his holes. Slick's balls would be happy to provide. She felt so full that she could almost imagine the cum sloshing around in her massive, heavy sack as she thrust, her thoughts consumed and burned away by the desire to just cum. Over and over again. She knew, somehow, that she would never run out of cum to share, nor milk, and as long as she was rutting into someone else, she didn't care either.

They were _coated_in a mess of sexual fluids. Juices, precum, spent cum dribbling out of Slick's pussy, not to mention the milk soaking their fur. It was so filthy, and yet somehow exactly right. The air was heavy with the scent of their mating, too, and filled with their shared moans of ecstasy.

Both Slick and Luka knew, somehow, that they'd only get slower and slower each time they came. They'd both felt it already, that sweet dissolute feeling of their thoughts practically squirting out as they'd cum before. It was so liberating. A shivering surrender to mindless bliss where no thoughts remained at all except the desire to rut and be rutted. Maybe there was a chance to stop just as her balls started tightening up, leaving her mental landscape even emptier bar for fantasies of cocks, pussies, asses, and massive milky breasts. Maybe. But if there was, she didn't have the willpower to do it.

So, Slick did the only thing she could do, and came. The first spasm of her cock flooded Luka's body with thick, warm cum. All previous orgasms she'd felt paled in comparison to it. This was the full experience, both of her cocks climaxing at once and pumping out what must've been at least ten times an average ejaculation, if not twenty. It was intense enough that she could feel her consciousness slipping away.

The immense heat and fullness Luka felt made him moan, too, though with his cock stretching his lips wide, not much of that needy moan was audible. There was such a deep sense of satisfaction accompanying every throb of Slick's cock, a warmth surging inside him and flooding both his bowels and his womb. He clenched as hard as he could around Slick's cocks, lovingly trying to prolong her orgasm as long as possible so he could, in turn, wallow in the sensation of her seed erupting into him. Only moments later, he reached his own peak, even if with all the pleasure dialled up so high, he didn't really know it was happening before the first rope of creamy cum splattered against the back of his throat.

Luka didn't really have a choice but to swallow with the sheer amount of his own cum shooting down his throat, but he wouldn't have chosen differently anyway. Between the pleasure and the wonderful taste of cum, he didn't even realize he'd stopped breathing to indulge in it before his vision started to dim. At that point, he reluctantly let go, gasping for air as the next few spurts of cum landed wetly onto his face instead.

That was how their day ended. Transformed as they both were, their orgasms were strong enough to make them both pass out, and so they did, collapsing into a pile of mixed fluids. That was also where they'd remain for the longest time, given how difficult moving around was getting with their oversized attributes. Where would they have gone, anyway? What more existed than the ecstasy of constant mating?

For Slick and Luka, certainly not much. Though once they did wake up, they'd certainly call some friends over, assuming either of them retained enough smarts to come up with a convincing reason. There only thing better than two extremely endowed herms was, after all, an entire orgy of them!
