Transformation Turnabout

Author: FangsScalesSkin

By the time the door to the room opened, Charlie had worn out her voice from shouting and had given up on tugging against the restraints holding her to the operating table.

"Oh good! You're awake!" The far-too-cheery voice was accompanied by the approach of a bizarrely-dressed figure in a white labcoat, goggles and a medical mask, and oversized black rubber gloves.

"Who the fuck - let me go, you little freak!" Whoever the fuck they were, they'd drugged and kidnapped and stripped her. Whatever came next could only get worse.

"I couldn't possibly do that, I'm afraid. It took far too long to secure a suitable test subject!" They walked across the room sounding totally unperturbed by Charlie's distress. She strained to see them out of the corner of her eye. They were pottering around at a desk covered in various flasks and beakers. She had no idea what any of them might contain, and she didn't want to.

"Test subject - no, no, no, no, I didn't agree to any of this, fuck you," Charlie rasped. There was an alarming gap in her memory, but she didn't have a chance to examine it any closer before the figure picked up a particular beaker of liquid and started to approach her.

"No, you didn't. But you'll help me all the same," the person tittered, and held the glass container up to the light. It caught the toxic-looking bright green fluid inside of it. There were bubbles rising to the surface.

There was no way Charlie was drinking that. She thrashed in her restraints to try to break free, but the heavy leather around her wrists and ankles and neck held. She screamed and cursed, but there was no reaction from the labcoat-clad freak except for a theatrical sigh.

They got closer, and she spat at them. It landed on their medical mask and dripped off.

"Now, there's no reason for that. This won't be so bad, I promise." The creep brought the beaker closer to her face. It let off an overpowering smell of crushed pine and herbs.

"Creep! FUCK OFF!" She shut her mouth as tight as possible after cursing them out as loudly as she could.

The weirdo winced, then sighed theatrically. "Honestly, you would think I were trying to poison you the way you're carrying on, not expand the boundaries of medical science."

They reached a rubber gauntlet clad hand towards Charlie's face. The reek of rubber filled her nostrils as they pinched her nose shut. Then held on.

Charlie held her breath as long as she could. She jerked her head from side to side, but the kidnapper's grip didn't falter.

She tried not to panic. That would only use up her oxygen sooner. She tried.

But either way, she ran out.

She gasped for breath, nearly choking when most of the contents of the beaker were poured into her mouth immediately after.

It burned like menthol. Charlie spat out as much as she could, but still ended up swallowing some. The taste wasn't horrible. Waiting to find out what it did was.

The liquid slid coldly down her throat, a line of chill following it and then spreading to her extremities.

Oh god, was she going to die? Was this what it felt like? She was going to die, wasn't she?

The chill settled in.

Then all her nerves ignited, like a match thrown into whiskey.

It burned and burned, too hot after the cold, but not quite pain.

Charlie pulled on her restraints, trying to escape the feeling, panting as she overheated. Every movement ached, but as the seconds passed it turned from discomfort to the sweet ache after exercise, after growth.

She strained to look down at herself, eyes bleary with tears and sweat. Her limbs were swelling and shifting. She didn't know what the hell was going on. It felt real, but it couldn't be real.

The burning intensified again, cresting as hair burst out of every inch of her skin. No, not hair. Fur. She was growing fur.

Thrashing like she could escape further changes, she felt her face pulled and warped into a snout, spitting out teeth as newer, sharper ones grew in.

"How interesting." The voice came from the side.

She had forgotten them. The one responsible for all this. Charlie snapped her jaws in their direction, claws on her lengthened hands and feet ready to swipe at them if she could only get free. Her heart pounded in her chest, strength coursing through her altered musculature as she strained against her restraints once more and this time heard the straps and fittings creek.

The thought of tearing her captor limb from limb for daring to restrain her was motivation to strain harder, but got lost when a further wave of heat coursed through her, down her spine in an ecstatic arch of her back that resolved into a tail. Then another wave, again down her spine. It settled between her legs, her heart still pounding but now in time with the aroused throbbing of her cunt. Prickles of heat bloomed in several spots down her chest that begged to be touched.

Charlie was still panting, still straining, still angry, but more and more, as her cunt throbbed and body brushed against the examination table, she was horny.

A final massive tug and her restraints gave way. Charlie leapt from the table, revelling in her own strength.

"Oh, that, that wasn't supposed to happen." The extremely fake scientist started backing away, expression hidden but voice sounding worried. They were backing towards the door.

"No, you don't," Charlie growled. She crowded them into a corner, the smell of fear escaping them no matter how they kept their spine straight. But fear wasn't the only thing she could smell off of them. Drool started to gather in the corner of her mouth.

"I'm sure we can come to some sort of - mutually acceptable agreement!" They held their hands up.

Charlie snarled. "Shut up and fuck me, then I'll decide what to do with you."

With a swipe of her claws, she shredded the front of their trousers, exposing them.

A fleshy looking lump fell out, bouncing across the floor. Charlie turned to stare at it, nonplussed. A packer.

"Whoops!" The dubious doctor giggled nervously. "I haven't exactly - come equipped - so if you'll let me go fetch a more suitable prosthetic...!"

"Nope. I'm not waiting. Figure it out." She was too horny for that.

Besides, if they were lying, she wouldn't get fucked or potentially turned back.

"Aha. Hmm. Give me a moment, please!" Whatever their deal was, they reeked as much of arousal as they still did of fear. They were into this.

The possibility that Charlie got turned into a big dog creature for them to get their kicks pissed her off. She growled again.

They flinched, then waved a hand placatingly. "I have it! Lie or sit back on the table, if you please."

"If you try to run off, I'll catch you." Her patience straining, Charlie considered tearing the mask off their face and shoving their nose in her crotch.

"No need." They grabbed a plastic bottle of clear liquid and pointed at the table. "Sit back on the table, please."

Charlie wrinkled her snout at them for daring to act in control of the situation again, but sat back and spread her legs. The cold air of the laboratory on her soaked slit made her gasp.

Pulling the rubber glove on their left hand all the way back to their elbow, the mad scientist or whatever they were stepped up to the table. "I probably don't even need the lubricant, actually, considering how wet you are."

They sounded too smug. It was almost a buzz kill.

"What, are you a fake gynaecologist as well as a fake scientist? Fistfuck me already before I decide I'm more pissed off than I am horny." Charlie growled at them, aware that drool was dripping from the side of her mouth but not caring.

"I have a real PhD," the real fake scientist muttered, pushing Charlie's legs apart more and rubbing their gloved fingers over her slit, slicking up their fingers and thumbing at Charlie's swollen, oversized clit. Charlie honestly didn't give a damn what they said so long as they didn't stop touching.

But she needed MORE. She needed to be fucked. The way she was now, a fist would be as good as any cock. Maybe better.

"Your other hand, in my snatch, now."

They didn't argue. Two fingers got put in her cunt. She could feel them making annoyingly gentle beckoning motions.

"I said hand. Not fingers. Fuck me. With. Your. Hand," Charlie ground out. Between the sharp teeth and how maddeningly horny she was, she didn't even sound like herself. But she didn't care.

"Patience, patience. Despite what you may believe, I do not want to hurt you."

They pulled out their hand and put it back with three fingers, starting to thrust in and out.

It still wasn't enough.

"Yeah, doc, I totally believe that after you force-fed me mystery liquid," Charlie said, as sarcastically as she could with three fingers in her cunt. Which was very sarcastic. "Stop messing around and fist me."

"If you want me to go right in with no warm-up, by all means."

"Get on with it!"

It was a shame this nerd didn't have a flesh-and-blood cock so she could shut their snooty commentary up by hopping on it. Then riding it until their hips turned to dust.

"If you say so." They shrugged and pulled their fingers out, made way too much of a show of pulling the gloves all the way back to their elbows, then grabbed her thigh with one hand. The other hand paused at the entrance of Charlie's dripping, swollen cunt. Charlie was about to bark at them again to get on with it when they slid their whole hand right inside.

Finally, the stretch was enough. She felt full. And it was so good. This was what she NEEDED.

"You really didn't need any stretching out," the researcher said. "Perhaps I should be taking notes."

"Just! Shut up! Fuck me already!" Why did her kidnapper have to be a yapper?!

They chuckled.

"As you wish."

Cornball ass. Before Charlie could bark at them again, they thrust their hand deeper. Then pulled it back. Then thrust in again. That felt... Wow. Her eyes crossed.

"Holy fuck. Do that again."

Her whole body shuddered when they complied. So, so full. So good. So hot. She was drooling again, but this time out of pleasure.

The doctor or whatever they were, it didn't matter so long as they kept fistfucking her. They'd stopped rubbing her clit. Couldn't do both at once. Which was annoying, but whatever. She pawed at herself instead, careful with her claws.

Charlie craned her head to get a better look. Damn, their whole hand was in her up to the wrist. That looked crazy. It was crazy hot, too. With the paw not rubbing her clit, she groped her chest while she watched, absently noting that the tender spots she wanted to touch earlier had swelled into full-on extra tits. Yeah, sure, why not. She'd been turned into a big wolf dog woman thing in some weird experiment and now the culprit was thrusting their whole hand in and out of her cunt. What were a few extra tits added to that. They were super sensitive, too. Almost too much.

Charlie rubbed her clit and her tits, working herself up to her peak. Her cunt squeezed around the hand being worked in and out of her. She was throbbing, deep ripples of pleasure following each thrust in.

She'd been turned into something weird and Charlie was going to make sure she got turned back. But right now her body felt so good.

Drool dripped from the end of her large tongue while she panted and rubbed her clit faster.

Yes. Yes. She was getting there. Yes.

No.

The thrusting was slowing down. Stopping.

Charlie snarled. How dare they!

"Sorry!! Sorry! Swapping hands, my arm is getting tired. Please don't eat me."

There was actual fear in the voice coming from behind the medical mask. Charlie felt bad. She wasn't snappish like that usually. Another reason to get turned back.

Even if making the person responsible scared was kind of hot.

Or was she just so horny she thought that?

She abandoned any more self reflection as soon as the other hand slid into her, cool enough to make her flinch. The difference in temperature made it feel somehow bigger. A big, amazing intrusion inside her.

The doctor was panting with effort. The sound made it all the better. There was something so hot about someone who acted all confident and in control earlier panting and sweating in effort, the brief sharp tang of their fear mixing with the smell of arousal underneath. Charlie want to rip the remains of that composure away with the medical mask. Maybe she should haul them down to suck on her clit after all...

The ripples of pleasure spread through her again. Her hips pushed against the next thrusts, driving them into her harder. She shook, tail thumping the table behind her.

This was it. This was fucking it. Oh god.

It felt so good.

Her back arched and her body tensed all at once, clenching down hard on the arm almost up to the elbow inside her. A howl rose from her throat, louder as her orgasm crested.

For a few moments she had no idea where she was. Nothing but her climax mattered.

She came down from it and gradually remembered the situation she was in. The weird experiment. And whose arm was inside her.

Fucking awkward.

She still felt good but it was definitely awkward.

"You seem to have enjoyed that. Now if you'll excuse me, I have some notes to take." They pulled their arm free and turned around to go wash their gloved hands off in a sink in the corner of the room. Then removed their gloves and picked up a clipboard and pen like Charlie wasn't even there.

"Um, what?? You still need to turn me back, you prick."

"The serum should wear off in about, oh... Three to six hours, if my calculations are correct. You're free to go, but if you do so before it wears off, you'll attract some attention. Your choice." They had turned their head to speak to her, then turned right back to their notes.

"Excuse me?! I don't even know where I am!"

"Your phone is on top of your clothes over on the cupboard over there." They pointed in the direction without looking up. "You surely have some kind of maps app, it can't be too hard to figure it out from there."

Charlie took back every doubt she had about wanting to scare them. They deserved it.

She could menace them some more, but she had a more fun idea. She glanced around the room, then found what she was looking for. The flask still a third full with the green stuff they made her drink.

The researcher was so engrossed in their note taking they didn't notice her picking it up, or that she had stepped right in front of them. Not until Charlie's clawed fingers grabbed hold of their face.

"What do you think you - guggbbh!"

Charlie's thumb wedged their mouth open and she quickly slid the top of flask between their teeth, tilting the flask until the contents poured into their mouth.

"Guhh. Whhuh," they spluttered. They swallowed the liquid. Didn't even try to spit it out.

With the flask empty, Charlie placed it to the side. The researcher grabbed it and placed it in a more secure spot.

"Do you know what you just did? I needed to run more tests on what was left in the flask! You're lucky I wrote down the formula!" Their irritation was cut short by shuddering and clutching at themself, stumbling back, and then sitting on the ground. "Oh, that... That burns. Too hot."

They tugged at the collar of their turtleneck sweater and wiped sweat from their brow.

"I should... Take off these clothes."

Charlie watched in fascination as they fumbled to take off their lab coat. They were too slow, limbs going abruptly rigid like every muscle was locked in place. Then their arms and legs bulged, seams ripping in places. Dark hair showed through the tears.

"My lab coat," they moaned weakly, collapsing back onto the floor as their muscles went slack again. Talk about priorities.

The doctor's nails popped off and claws grew in their place as they scrabbled at the ground. The cords holding their medical mask in place snapped as their face stretched out, pulled into a short half bestial muzzle. They didn't look like Charlie. Maybe because of the half dose?

She nearly didn't notice the next thing at first. The glistening pinkish nub that poked out from the ripped front of their pants. It was getting bigger. And bigger. Drooling, Charlie watched their cock grow and swell up, narrow at the tip and then swollen and bulbous at the base.

The transformed doctor pushed themself up to a seated position and wrapped a hand around their cock, muzzle open in surprise.

"Fuck, it must've... Reacted with the T in my system or something." They sounded completely in awe. "I'm so horny all of a sudden. Is that why?"

"Actually, it's because you accidentally made a super powerful aphrodisiac part of your wolfman potion or whatever it is." Charlie leaned over and pulled their hand away from their monster cock, despite their protests. "By which I mean I'm still fucking horny so you better let me ride that thing instead of jerking yourself off like a chump."

They turned an unreadable expression towards her, the goggles still over their eyes despite the changed shape of their face.

"Weren't you leaving? Now that you finished trying to... Trying to sabotage my experiment."

"Sabotage?" Charlie rolled her eyes. "Haven't you ever heard of getting a taste of your own medicine?"

She crouched down over the tip of their cock, not missing the way their nose twitched and breath sped up as she held her dripping cunt open with two fingers.

"But you know what, I decided I'm gonna stick around. Ride this out until I change back. Don't tell me you're able to resist this. I know how horny you are right now."

Charlie was still plenty turned on, but not desperately, insanely turned on like earlier. She had the upper hand.

"Yes, yes, I mean... No, I..." They struggled for words, their clawed hands running back through their hair for a moment. Then they grabbed at Charlie's hips and tried to pull her down onto their cock. Tried to. Because Charlie was stronger like this. And she used her strength to stay crouched exactly where she was, grinning at the researcher.

They growled at her. "Stop that. Get down here already."

"I dunno, I think you should say please first instead of just trying to grab me." This was fun. Seeing this snooty scientist lose their cool was far too fun.

"Would you stop - teasing! I feel like - like - like I'm going to lose brain cells if I don't fuck something right now."

"Woooow, you really need to learn some manners," Charlie said, standing up and breaking the hold they had on her hips.

The researcher tried to grab at her again, scrambling back to their feet. They seemed to have forgotten they could jerk off about it. Maybe they were already losing brain cells.

"Get back here!" They grabbed her wrist.

"Rude, much?" Charlie pulled her wrist free. "If you want to fuck me you better be more polite about it." Honestly, she really did want their dick, but toying with them was too entertaining to pass up. And if anything, she was being too nice. They kidnapped her and made her drink weird potions and everything.

"Shit - I mean, I'm sorry? Please?" The words were edged with a whine, and Charlie watched drool gather at the corners of their mouth. Was that what she looked like earlier?

Freaky. But the hot kind of freaky.

"Let me fuck you. Please." Their breathing was harsh, their dick bobbing erect between their thighs.

Yeah, alright. If Charlie drew it out too much they might remember they could just jack off. And she was still really horny, too. Not as much as earlier. But too much to keep teasing.

"Wow, you are desperate, huh? Good enough." Charlie turned around, got down on her hands and knees and looked back at them. "Come get it."

With an animalistic growl, they were on her, pressing in close against her back. Her heart sped up and she swore she felt herself get wetter. The point of the researcher's cock slid between her legs as they tried to line up and missed in their eagerness. Before they could get some idea about being lazy and fucking her thighs, Charlie took hold of the tip and lined it up with her slit. It slid in with no effort, their hips pressing closer while Charlie slid her knees apart more to give better access.

She felt the shaft filling her up and the widest part of the knot just inside her entrance, stretching her and almost sliding out when the doctor's hips twitched any amount backwards. She wanted to hold on, keep it there exactly where she needed it. If it slipped out she was going to lose her mind. She shoved herself back on it, letting out a groan.

The doctor thrust in and out in a frantic rhythm, panting and growling. Charlie felt their drool drip down on her back and their claws at her sides, digging in hard enough only her fur stopped her getting hurt.

This was it. Getting fucked down on all fours like nothing more than an animal. She couldn't remember if this was something she always liked. Maybe what she'd been turned into was influencing her. She'd untangle it later. Right now she was getting fucked hard.

"C'mon, harder," Charlie teased, getting a snarl in response.

She could take it, too. The doctor's hips slapped against her ass with every thrust into her. Their knot stretched her out every time they hilted and left her feeling empty every time they pulled back. Charlie met each thrust eagerly.

The most warning she got that they were close was a wordless growl, the thrusts into her getting annoyingly erratic. They hilted again and Charlie felt their knot swell up inside her, locking her in place. It was absurdly hot. With how stretched she was earlier, there wasn't the discomfort she half expected. It just felt good.

But there was something missing.

"Did you, uh, did you cum? I didn't feel you, like, squirting inside me." Whatever the answer, she was pushing and pulling back and forth against the length inside her, the knot dragging pleasurably against the walls of her hole. She rubbed her clit and felt her own climax getting close.

The scientist let out a groan, leaning on top of her.

"Squirting...?" They sounded dazed. There was a long pause before they continued. "Oh, you mean... Ejaculation. You seem to have forgotten that I don't have any testes to speak of."

Charlie couldn't be bothered to mention that they grew a big werewolf dick, so balls weren't a crazy idea. She was too busy. The position wasn't totally working for her now the scientist had stopped thrusting. So she pushed back and toppled them over onto the ground so she was sitting on their dick instead then started rocking back and forth on top of it.

"That manoeuvre was entirely uncalled for..." They grumbled, but Charlie's movements got an occasional gasp out of them. "Once that swelling goes down, I need to record my," they gasped and then continued, "record my observations about this entire episode."

Her back was to them, so Charlie just ignored the rest of their rambling about the experiment and rubbed her way to coming. Her limbs trembled and she moaned as pleasure shivered through her. Even if it wasn't as dramatic as the previous one, it made her toes curl and her tail thump behind her.

Damn, that felt good. It was so easy to let loose like this.

She could go again. And again.

What did they say? Three to six hours?

"I think your observations can wait for another, say, three to six hours. While we fuck some more."

"What? I can't wait that long to make my notes. Are you mad?" They sounded annoyed, but she felt their cock twitch inside her.

Charlie rocked back and forth on the scientist's still swollen knot, extremely pleased when she heard a low moan out of them. She smirked to herself.

"Nope. I think you can, actually. Least you can do to make up for, oh, I don't know, kidnapping me. Face it, you're getting horny again already."

When Charlie followed her words by bouncing on their dick and didn't get any further smartass answers, only harsh breathing and clawed hands grasping her hips, she knew she had won.
