#91 of Transformation Stories

Let's shift gears back to the transformation fans for a little bit, shall we?

In this story for our old friend Simpleness, we revisit Fred, a wolf who has a bad habit of turning his party guests into lust-driven members of a slowly growing pack of females. Though he's already happy with his relationship with Jesse, he's ready to feed a few more muzzles, and the first of his targets is Justin, a feline with a bullish attitude and a pompous flair that makes him the perfect person to take down a peg.

Tipsy and looking for a craft beer, Justin follows Fred inside at an evening barbecue, only to be tricked into drinking something much stronger than the average ale. The changes are almost immediate, and before long, Justin is writhing on the floor, cursing Fred's name while begging for his new womb to be filled with pups...

Vulpines mated for life, but when it came to lupines, one lover wasn't always enough to keep them satisfied.

Fred wasn't dissatisfied with his love life whatsoever; rather, it would have been more accurate to say that he was terribly greedy, to the point that his better judgment was taking a backseat to his desires as the evening sun began setting on another successful barbecue at his house.

"Hey, Fred? You got anything stronger than the piss water?" one of his buddies had been overserved, but that was no excuse to complain about the choice of beer, when it was free to drink. "I could go for a step up from this if you've got anything...y'know..._special_on tap in the kitchen?"

A known beer snob and a feline that wasn't afraid to flaunt his promiscuity around the party, Justin stuck out in the sunlight with a coat of fur that was blacker than the pits of his eyes, but they might have looked that much darker, thanks to the presence of such lively bands of green around them. On a spring evening that felt more like summer, a white t-shirt and cargo shorts gave him quite the lackadaisical appearance, betraying the rest of his snobby stereotype, but to say that everyone at the party was tired of his pointless criticisms would have been something of an understatement.

He had no idea what he was in for when Fred took a step away from the grill and patted him on the shoulder. "As a matter of fact, I've got something sitting out on the counter right now! I was gonna go open it myself, but you've probably got a better palette for it...don't go telling the others about it, all right?"

Tipsy enough that he didn't bother questioning Fred's motives, Justin smiled and walked slowly into the house, wanting to hide any evidence of a stumble in his step. "You always were the kinda guy to have something crazy stashed away," the feline claimed. "Can't wait to see what it is!"

"I'm sure you'll love it," Fred called after him, immediately taking notice of the stumble and shaking his head. "Hey, can someone take over for me, here? I've gotta go check on something."

There was a line of people eager to stand at the grill so they could prove their cooking skills to the crowd; Fred was just finished saying the words when the spatula left his paw and he shrugged off his apron, knowing how quickly Justin would have popped the top on the dark bottle.

If the feline were foolish enough to approach the drink like a true craft beer aficionado, he never would have guessed what the contents really were, as a smell of lightly roasted vanilla flooded his nostrils. "Gotta have some sweeter malts in there...I could just sit here and sniff this all day!" he was giddy as he poured the thick liquid into a pint glass, watching a halo of tan form at the edges as the mysterious fluid drew closer to the top rim.

He was putting the first sip to his lips as Fred stepped inside and grabbed himself another common beer from the fridge, unconcerned with trying to keep up with Justin's tastes. "It's a lot better if you drink it, you know," he teased, having caught Justin's words as he stepped inside. "But what do I know? You're the local craft expert, after all..."

Rolling his eyes as the first gulp of carbonated liquid poured over his tongue, Justin went through all of the steps as he tossed the drink from the left side of his mouth to the right, and even allowed it to sit on the back of his tongue before he swallowed; it was even sweeter than the aroma would suggest, to the point that it almost turned the feline off.

"This almost tastes like alcoholic syrup," he oversimplified the drink in his paw once again, this time insulting Fred in a way that was more than a complaint about the free stuff. That particular bottle came to the wolf at a very high price, and as he stared expectantly at Justin, the feline realized his faux pas and took another sip. "Uh, a...although, it does get _better_with every sip, so there's that!"

"Have another gulp or two," Fred suggested. "I think once you get about halfway down your glass, you'll really start to appreciate the deeper complexities of that particular drink...I'm sure someone with your discerning tastes won't have any problem figuring out what I mean."

Justin was being manipulated with such ease that Fred could have been tugging the cat on a string and he wouldn't have been any wiser to it. "If you say so, dude. I feel like you could drink this with a slice of cake and it would pair up just fine!"

Fred rolled his eyes. "I can never tell if you're complimenting a beer or tearing it down, the way you try to describe these things..."

"I mean, I can see why someone else might enjoy this. I'm not sure if it's for me, though," Justin claimed, though he was still taking sips of it as he went along. "Honestly, I think I might be allergic to it. It's giving me a bit of a tingle in my lips..."

It was hard for Fred to hide his excitement at that, but he didn't want to seem like he was celebrating something that could actually be quite terrible for his friend. "There's nothing in there that you should be allergic to, dude. I wouldn't have offered it to you otherwise!"

"If you say so," Justin groaned. Despite his ongoing complaints, he took another swig from the glass as he warmed up to the flavor, and that was already more than enough to seal the deal. "Feels like maybe I'd need to have a second glass to really _appreciate_the complexities of it."

"Trust me, one glass is more than enough," Fred warned him. "If you don't like your lips tingling, you'll definitely want to stop there."

Fred knew that it didn't matter if Justin decided to carry on with it or not: the change was already in motion, though a tipsy feline would be slow to pick up on that as he made his way past the halfway point of the glass. "No wounded soldiers though, right? I at least have to finish this one!"

"You don't really have to," Fred suggested. "I think you just like getting drunk on whatever people are willing to hand over, while complaining that you've had something better. It's kind of a lousy trait."

Offering a wink to Justin, but knowing that wouldn't be enough to soothe him, Fred was prepared for the feline to get in his face. "Oh, come on! I'm not that bad about it!" he argued, though he immediately questioned how much he'd had to drink that night when he found himself looking up to meet with Fred's gaze. "Uhm...dude? Did you get taller or something? I was pretty sure we were fully grown adults."

Gazing down and checking to see if Fred had boots or lifters on, Justin caught sight of his calves getting slimmer, and his thighs following proportion in such a rapid fashion that he couldn't hide his panic. "No, I'm still the same height as I ever was," Fred murmured. "Perhaps you're already so old that you've started shrinking."

"Very funny," Justin's eyes rolled this time as he gave Fred a solid poke in the middle of the chest, but something about the gesture didn't carry the same kind of weight that it used to, as his digit felt smaller and thinner than it was a moment ago. "Did...did you put some kind of flesh eating stuff in that beer, dude?"

"You still think that was a beer you just drank? That tells me all I need to know about your sophisticated palette," Fred mocked his slowly shrinking friend, just in time for his diminishing height to settle. "Though, I'm sure you'll find you have a new taste for other things before too long, if the potion did what it was supposed to do."

" Potion?!" Justin was furious, but every bit of rage that he felt was stoking a different fire within, as his body continued to shift. Rather than shrinking down any further or slimming at the ends of his limbs, he felt his center of gravity shift as he went to throw a punch, and just that easily, he fell forward into Fred's arms, losing his balance in the middle of such a simple act. "What...what the hell was that, some kind of date rape drug?"

"Nothing of the sort," Fred assured him. "You're tipsy...and you're also getting some nice, wide hips, just like I hoped you would. Makes throwing a punch the way you normally would a bit more difficult!"

Twitching fingers and eager claws wanted to dig in to Fred's neck, but Justin was struggling to do anything beyond stroking the nape with a delicate touch, as if someone else was holding his paw on a string and toying with it. "Mind explaining why I'm fondling your shoulder instead of ripping out your spine, then?"

"Just the normal side effects of drinking my favorite beer," Fred used the false title once more to tease Justin, who was still uneasy on his paws. "Uncontrollable lust for the first 24 hours, post consumption. I did try to warn you about going through it too quickly, didn't I?"

"Would that have made any difference?"

Fred snickered. "No, probably not. I do appreciate you testing out this newest batch of the formula for me, though. Looks like it works even faster than the original stuff!"

The recipe for a famous chemical cocktail, known as the "Heated Wolfess," was always being improved. It was just a little bit at a time, and Fred didn't dare to give out the name of his supplier, but he always kept a few bottles of the stuff on hand to make sure that his pack would continue to grow, even when he didn't have willing vectors for the role of a new bitch.

Justin wasn't the type to go willingly, at first, but the effects of the potion were every bit as quick to act as they were far to reach. He didn't want to accept the burning fires of lust that were rising up from the pit of his crotch, but they were getting worse by the second, even as he could feel something between his legs starting to shift. His widening hips, narrowing torso and softening chest were all obvious clues to what was happening to him, but when they all took place at the same time, the black-furred feline couldn't help being overwhelmed, until he spilled over to the floor, tripping over his dizzied legs and nearly falling out of his jeans.

His backside was just large enough to keep them from falling all the way down, but when he landed, he expected to feel a few things twisted up in the front...but they'd become so small and retracted that there was no danger of them being injured that way. "Okay...you are so in for it when I can stand upright again..."

Fred wasn't expecting the potion to have such a nauseating effect on Justin, but the process happening in such a rapid fashion was setting the poor feline's body against itself, even as the last of his cat-like features hardened. A short, stout muzzle was growing longer as it rested against the cool tiles of the kitchen, and the rough, spiky tongue that he was used to had grown wide and soft, hardly fitting in his own mouth anymore.

Shifting eyes gazed up at the one responsible for all the trouble, but there was no way for Justin to feel anger; he was too far gone with forced arousal, and he was running out of steam to fight at as he explored the shifting flesh of his cock as it continued easing further back.

"Sorry, but you're gonna have to be on the bottom for your first round. It's only fair to the others," Fred claimed, setting a standard for a pack that didn't quite exist yet. "Besides, I'm sure you'll come to appreciate being on bottom, once you finish taking a proper shape...though I do like what I'm seeing so far."

Curvier and bustier than any other female he'd ever been with before, Justin was closer to a Justine at that point, and it was only getting worse as feline digits thickened up with canine strength around the tip of a member; that tip was all that remained, and under the excess skin left behind, a clit began forming, with a hood holding shape over the top of it.

Justin couldn't point to the exact moment that his full, heavy orbs finally disappeared up inside of his body, but when he reached just behind the tiny nub that was left of his dick, there was only the a growing part of soft, delicate flesh, so tender that he couldn't possibly mistake its place and purpose.

She knew there was no going back now, but her frustration at that fact was completely overridden by the flickering, agitated sway of a tufty, lupine tail. "If you like looking at it so much," she whispered, as she rolled over onto her hands and knees, "Why don't you come give it a closer inspection? You'd better make sure everything took...don't be afraid to feel it, if you're worried."

To some, that would have been a bit too welcoming of a statement, but Fred took it at face value, seeing the complete shift from the vertical slits of a feline eye had given way to bright, yellow orbs of lupine gold. "And here I thought you might try and rip my face off if I got too close," Fred murmured, stepping past Justine and leaving her to whimper, at least, until he closed the door to the kitchen and locked it for a moment. The blinds were turned, leaving the setting sun out of the equation and forcing Justine's senses to heighten at the moment of truth, so that no part of the new experience would be missed.

Fred had no idea what it was like to experience the ways of physical love as a woman, but he wanted Justine to learn of them as quickly as possible, as the sway of her tail spread the delightful aroma of her heat around the kitchen.

"Not saying I won't do that later," she cautioned him, "But right now, I honestly don't think I can move without fingering myself, and since I'd have no idea what I was doing...c-could you please just hurry up and fuck me already?"

From thin, untouched folds, arousal was already starting to ease down Justine's virgin petals, leaving them with a glisten of lust that was just barely visible in the low light of the kitchen. She'd struggle with the first pass no matter how desperate she was, but there was plenty of time for more of her natural moisture to build as Fred took his time easing out of his jeans, wanting to give Justine a good, long look at his cock as it emerged from the warm and comfortable depths of his sheath.

Licking her lips before she even knew how wonderful it would feel inside of her, Justine looked back obediently at the pulsing flesh of marbled red and pink, her backside swaying and her claws scraping the floor as she watched him kneel behind her with an intentionally sloth-like gait. "Even I wasn't expecting the potion to work quite so fast," Fred explained, as he gripped Justine's backside and held her steady; even that simple touch was enough to leave her gasping. "I didn't want to go at such a perfect specimen until I was ready...I'm sure you understand."

"Doesn't matter if you were r-ready or not," Justine argued, her fangs gritting as she began pumping back at Fred's member, even before it was remotely close to guiding inside of her. "This is your fault, so hurry it up already!"

A rapid transformation and insatiable lust were all common side effects of drinking a "Heated Wolfess" potion, but Justine was exhibiting even greater symptoms than what Fred was used to, and her claws were making quite the pattern on his kitchen floor, as her tail tried looping around his hips.

Seeing such desperation left his cock to drool a hint of warm, slick precum into the part of her labia, as his tapered tip eased them open and left her to suck in a gasp of tense excitement. "Relax...breathe as it goes in," he warned her immediately, knowing that he'd lose himself in the moment as soon as he felt her warmth against his rod; keeping control as long as he had felt like a crowning achievement.

He knew that Justine wouldn't have the self-control to keep from ruining herself, so his claws dug in tight against her tender flesh and held her in place, even as her knees trembled and her thighs quivered with each inch of the male that she took. "Bout...f-fucking time," she whimpered, trying to sound ferocious and aggressive at her most vulnerable moment, but as she was deflowered in the kitchen, she cried out with such a blend of mild pain and overwhelming pleasure that she knew the party could hear every ounce of both sensations. "Fred...d-damn...you're too f-fucking big! _Nnngh..._g-give me more, you fucking jerk!"

Knowing that she couldn't reconcile her need for his entire member with her own limitations, Justine had no choice but to let him guide his length into her eager cunt with a slow and easy pace, to start. It was proper form for the canine pair, as his arms draped down over her slender tummy and kept her close, but the effects of the potion didn't always stay with the one who consumed it.

Just as Fred feared, he was consumed by it, to a lesser extent: the first minute would be the only gentle thrusts that Justine would ever know.

"W...Wait, Fred! Not so hard!" she tried to plead with him as her body did all that it could to adapt, but there was no keeping up with the sudden weight and depth of his pounding hips. "Fuck! Fuck, that's too much!"

Any semblance of control that either one of the beasts had was lost to the lustful air that consumed them; there was no turning back for Fred, who dug his claws in anew and held Justine still for him as his cock pummeled the deepest reaches of her womanhood and spread it wide around his heavy, tapered length. Mingled cries for mercy and more danced together until they faded into a whimper of passion, leaving Justine to pant rapidly, having no choice but to yield to her lover like the bitch that she was.

She knew how much it would hurt when his knot began spreading at her tender folds, but even then, she could only quiver with delight and hold still for the tie that she knew was coming...even when her womb was completely flooded with his cum, forcing excess to spill down to the floor in a heated pool, she didn't fight back any longer.

Beyond pain and even beyond pleasure, there was a relief to feeling his seed across her inner muscles, teasing them with the possibility of a permanent departure from the frustration of her heat.

The stronger formula, however, had other plans for her...
