"What is this test they've got scheduled?"

"I don't know. After all those failures, someone higher up got an idea they wanted to try out."

Mewtwo walked along behind the scientists as they chattered. A frown rolled across the Pokémon's face under the mask. Not that either of the humans would see it. Strange that they make all these noises with their mouths. Yet demand I talk to them mind to mind, only to silence me with this helmet. Their head rolled slightly and they pushed. The helmet did its job by absorbing the energy and redirecting it down through the rest of the suit. Strange that they didn't have the full suit on today. Plates along their back, some on their arms, but that was it.

Down sterile halls and into a room. One of the lab techs went to mess about with some of the equipment while the other turned to face Mewtwo. "Come here," a hand gesture, "knees here." He gestured towards a strange bench. Mewtwo had seen more than their fair share of examination tables, but this was different. Pads slung low, spread out, a long and narrow segment, straps, and braces. Mewtwo did as asked, pressing knees into the pads. The tech uttered, "Good," before moving around. Wrapping thick, padded straps around their thigh, calves, and even ankles. "Lean forward." Again, Mewtwo did as requested. Laying down on that narrow segment. Feeling rather strange as the sections against their thighs shifted a little, spread, and locked into place.

"Wonderful. Now just relax and place your hands here." Padded grips and armrests. Mewtwo laid their arms there and watched as more straps were fed into more buckles and tightened. "Tail up or to the side?"

A distracted, "Side, they've got a sleeve for it here." The techs swapped. One retrieving the strange sleeve, while the other began to plug hoses and cables into the helmet. "Keep your mind clear. We don't want a feedback into the system right now."

"My mind is nothing but clear right now." The voice, Mewtwo's voice, echoed through the helmet before being translated into a digital noise through a speaker.

That got a laugh. "What, not nervous for your first time in bondage? Not going to ask about a safe word or anything like that?" Hands on their tail made Mewtwo want to turn and look, but something clanged against the helmet. Limiting just how much they could look.

"This is serious science here, you know. We have to see what it's capable of."

A dismissive, "Yeah yeah. Crush tanks, pull helicopters from the sky with its mind, fighting other Pokémon, and kinky sex games. The uses are endless really." Pressure on their tail, the sleeve covered most of it and got laced up. Another strap made Mewtwo lift and curl their tail, swinging it off to the side. "Okay, everything is secured. Nothing seems to be pinching." A light tap to the helmet, "Any discomfort?"

"I am rarely comfortable, but nothing is actively discomforting."

A sighed, "Verbose, huh? Boys upstairs have really been feeding it lots of schooling, huh?"

Its mind is incredible. The amount of storage and processing? We haven't begun to calculate what it's capable of. Watch." A button press and the helmets screen lit up for a second, images flashing too fast for a human mind to comprehend.

"What was that?"

The answer, if there was one, was drown out by the sound of Mewtwo's heart pounding. New ideas, concepts, and instructions flooded their mind in a flash. Every image, each symbol carefully crafted to trigger programming that had been fed into the Pokémon's mind since its creations. Instructions, detailed ones, on what the scientists wanted. That thunderous beat spread out, rippling through the Pokémon's body. Short fur bristled and shivered as the commands rolled down it... Her body.

A new idea, the concept of Gender. Breasts, vagina, ovaries, womb, bone structure, and more. The Pokémon's once flat chest began to swell. Pectoral muscles growing softer, more plush and larger. Nipples rose under the fur to just start to peek out. Fatty tissue, created out of the aether by the power of the Pokémon's psychic will, collected within her chest. "Unnghh," came a little gasp under the helmet.

It wasn't just breasts. Hips began to reshape as well. Growing rounder, thicker, and more feminine. Thighs thickened as well in turn. Reaching some ideal programmed in by someone in another lab.

Then came the strangest feeling of all. A low, burning churn in her core. New organs began to grow and shift. Where there had been a simple hole for taking care of biological wastes, now muscles began to twist and grow. Spiraling into a tunnel within her depths. Feeding up to a new sphincter, her cervix. The whole itself reshaped and grew. Splitting off into an anus and separate vagina. Nerves sparked to life. Little jolts of tingling, pain, pleasure, hot, and cold as they sprang into being and began to communicate with the greater whole.

A whistle. A click of a stopwatch. "Time to gender completion. Thirty-two seconds."

"You sure it's complete?"

The squeak of a chair, "The computer seems to think so, and..." footsteps. A lab coat came into the periphery of her vision. She felt a hand on her new, rounder rear, under her thicker tail base. Fingers spreading open her freshly formed genitals. The cold chill of metal made her jump against the bonds as a lubricated tool slid into her still quivering vagina. "Looks all good in here. Cervical entry, vagina walls, and..." Fingers dipped to circle an area at the forefront of her new hole. Pleasure, something she hadn't felt before, shot up her spine and made her thrash again. "There's the clitoris."

More steps, "Huh, so that's where it is." Fingers joined the ones already back there. Playing up and down against her new bundle of nerves. Mewtwo shuddered, hunched, and pulled at the straps as new sensations raced up and down her spine. Rattled around her pussy, making new muscles quiver as arousal began to build in her. A sensation that was alien, yet somehow also familiar. She knew the science and information behind it. All that had been fed into her, but she'd never had a concept of gender for herself until now. Not until she could feel how it affected her physically. Now she could conceptualize it more fully with each passing moment.

"Fuck, look how wet she's getting." Thoughts, not hers, intruded in on her, followed by a rush of foreign excitement. it took her a moment to realize the thoughts were coming from the tech behind her. Another beat before she traced them back. Skin to skin contact, bypassing the helmet's blockers. His flesh touching bundles of fresh, raw nerves that were only getting more sensitive by the moment. "Wonder if I can make her squirt." The thoughts had a devious, devilish tone to them.

Smug, eager excitement crashed against her as the fingers dove deeper. A second hand came into the mix. Two fingers pressed deep, hooked, and pressed against something inside her. The others rubbed and drummed over her clit. Mewtwo arched, letting out gasping, panting cries as feeling she couldn't describe began to crash through her. Those fingers searched out and found spots within her that made lights flash and explode behind her eyes. "She's a bit loud, isn't she? Cut the vocoder." The synthetic, digitized voice went silent, leaving only the muffled noises from behind the helmet. "Good, much better. Now..." Fingers hooked and pressed mercilessly. She thrashed against the bonds, metal and synthetic fabric creaked and stretched, but held. She felt something new inside her. A tightness that grew hotter and more compact with each stroke. It felt like an explosion going off in slow motion. The collapse of her self towards the center of that. Getting compacted tighter and tighter before the inevitable release.

For a moment, she was sure she'd gone blind. Her vision went wide and a roaring filled her senses. Fur bristled and legs tried to kick, toes curling. Mewtwo might have snarled, could have called out, but she couldn't be sure. Somewhere in the near distance a call of, "Wow, look at that! She's a real squinter isn't she!" accompanied smug satisfaction, passed through the invading fingers. Pressing against her shuddering walls and conducting up through her spine to her core.

"The fuck?! Aw, it got on my shoes. Really? Get your fingers out of her." A mutter of complaint, but the hands pulled back. Not before the tech delivered a firm smack to her rear. The pain giving her something to focus on in that sea of pleasure. Mewtwo clung to that and panted. Every fiber of her being humming with things she didn't know could have existed until mere moments ago.

"Yeah yeah, what's up first?" The fingerer muttered as he wiped his hands off on her hips and walked to his companion.

A click of a tongue, a mutter, "The boys want to run ghost types first. They suggest it will make her more compliant. Theorizing that the type advantage might do something to her." Chair creaked and a low hum as the tech called a couple Pokéballs to the system. "Looks like... Gengar and Haunter up first."

Chuckling, "Two at once? Poor thing is gonna be mindless before they're done." The click of Pokéballs being retrieved. She rolled her head, spotting the two techs at the edge of her vision. Both sitting by some computer consoles. Clipboards at the ready, each holding a Pokéball, and just past them? A bank of monitors with readouts, displays, graphs, and camera feeds. Feeds that showed her, bound and exposed, from multiple angles.

"Might as well use both them at once. They give me the creeps. We can go one on one after that. Ready? Recording? Okay, Subject Mewtwo. Stress test Zero-One beginning in: three, two, one."

Twin flash of light, this time from the spheres they held. Blinding light swirled and grew into the dark purple forms of a Gengar and Haunter. "Alright boys, your time to shine. Have at it." The Pokémon looked from the techs, over to Mewtwo, then at each other. Wicked grins forming on their faces as they began to shake hands at each other. A disappointed noise from Gengar, a cackle from Haunter. Again, this time Gengar cackled and Haunter fumed. Third time, same result, Gengar shaking its fist at the other ghost before thudding over. Thick frame swaying with a swagger. Fingers tapped against the armor, down to her bare skin. Flesh crawled against the strange, tingling chill that came off the touch. She squirmed and that only made Gengar cackle. A deep noise that sent shivers up her spine and made her fur stand on end.

Whatever disagreement they had, it didn't slow either male. While Gengar was taking his time moving down her body, Haunter went right for her face. Floating hands grabbed the helmet and pulled his floating form towards her face. A strange scent filled her nose. Earthy, damp, and chilly, a very strange sensation that made her muzzle wrinkle. Then something bumped her mouth, unseen but felt. She tried to pull her head away, but between the straps and the grip on the helm, she couldn't turn her head far. Another bump to her nose, something told her to keep her mouth shut. Lips curled and she growled, the noise sharp and feline as she voiced her displeasure.

"Haunter!" came the complaint.

A laughing, "Gen... Gar," before the creature moved behind her. She could see the monitor out of the corner of her eye. Watched as he grabbed her haunches and leaned forward. That grip biting cold, breath washing over her. Out came his tongue, rolling out of a massive, grinning mouth. He licked his lips then let it leap up and slap against her tender folds. Saliva coated her backside as he licked, spreading ectoplasmic spit across her. Nerves spiked and sparked, going haywire the instant his tongue swept over them. Mewtwo jolted and cried out in alarm.

That's what Haunter had been waiting for. He'd asked his companion to help and Gengar was more than happy. As her mouth flew open, he pressed forward. Unseen, phantasmagorical phallus dove right across her lips and fangs. Mewtwo reacted out of instinct, trying to clamp her teeth back down, shove him with her tongue, something, anything! But the moment her tongue touched his ghostly flesh, that tingling spread across her senses. Muscles relaxed and went strangely numb. "Haaaaunter," he sighed out. "That's it, you psychic slut. Tastes good doesn't it?" the ghostly thoughts flitted across her senses. Like a voice down a dark hallway. "Wonder how much she can take," came a breath before that invisible presence pressed deeper. Across the back of her tongue, to her throat, then down. Mewtwo gagged, or tried to. All that came out was a choking noise as her muscles began to betray her. Refusing to clench and push out the invader.

"HaUauanter!"came the pleased sigh. "That's it, right to the fucking balls!" Unseen hips rocked, jabbing that ghostly cock down her gullet.

Another slow lick from Gengar. "Fuck, she tastes so good." His tongue swept around her pussy then inside. "Brand fucking new too, I can't wait to just ruin this cunt." Raw desire and anticipation pressed against her as the tongue dove so deep. Pressing against her cervix, threatening to shove through the tight muscle. Gengar laughed again, the sound echoing into the room and shaking her to the core. All while his tongue sloppily dove in and out of her body, lapping at her walls. That same numbing sensation spread through her. Cool, deadening, yet at the same time, it somehow enhanced what she was feeling. She could feel each flex of his tongue, every single taste bud as they rasped against her walls.

"Mmmphh, ggnnnk!" was all she could do. Choking on the ghostly cock in her throat. Her body heaved, threatened a cough that never made it out, and she felt her eyes roll in her head.

"Hahahahaunter," Haunter cackled. "Love the noise of a slut choking on my dick. Beg she's making the best face right now."

"Gegegegengar,” came the shuddering laugh."You think that's good, wonder how she'll react to me." The tongue slurped back and the larger male stood up. Something that was blunt, both hot and cold, pressed against her licked slit. A beat of pressure, a moment of grinding. Then he shoved his cock into her. Walls spread open around an invisible length. Lights flashed and popped behind her eyes as Mewtwo whined and arched. Blunt tip slammed against cervix and ground there.

Relief as Haunter pulled back just enough for an explosive cough to burst from her, mixing with the gasp of pleasure and pain at the sudden and deep penetration. "Gengaaar," he breathed out. "Nothing like fucking a virgin. Though doubt the killjoys will let me take long, so..."

There was a deep pulling sensation in her core as he drew back. Insides quivered around a cock none could see before he slammed back in. Hammering into her untested depths. Hands closed on her hips as the Pokémon behind her grunted and began to throw himself into her. His phantasmal mass crashed off her backside, driving her forward into the Haunter. Who gladly held her head and rocked his hips forward. Driving himself deep into her gullet with each impact, then drawing away as the Gengar wrenched her backwards.

"By the... Did we have to get the largest Gengar in stock? Look at how much he's stretching her out. I swear, I can see his cock in her gut."

A pen scratched on the paper, "I'm more curious that we can't see his penis. Most have a slit, sheath, or something. Does this mean he's just always out and letting it swing around?"

Their discussion faded to the back of her mind as Mewtwo grabbed at the armrests. Her world faded into sensations and colors. The deep purple of Haunter groin peeking through her helmet. Steady impact of balls off her chin. Within a few thrusts, her throat was starting to sting, then tingle as precum poured down her throat. A similar situation at her rear. Inner muscles quivering. Flashing from hot to cold, numb to tingling and burning, as ghostly precum filled her. Starting to spill out as the thrusts rained down faster, harder.

"Haaaaunter," came the growl."Gonna cum!" Ghostly hands wrapped under her chin and grabbed the top of her head. Haunter rocked back until just his tip was inside her mouth. She could feel his tip swell, throb, and then the indescribable taste of ectoplasmic spunk filled her mouth. "Swallow it," Mewtwo felt it start to fill her cheeks, threatening to spill over her lips and rush down her throat. "_ SWALLOW! " hands shook her head and the psychic couldn't help but do as ordered. Her mind starting to fracture already. _"That's a good slut," came the breathless sigh as she gulped down the mouthful. Feeling that numbing heat start to spread over her throat, down her stomach, and out from her.

No that she would get relief. "Geeeengar!"he sighed. "Bet that was good. Fuck she's gonna milk me dry back here!" Fast, shallow thrusts hammered his cock so deep inside her. Each battering ram threatened to drive the breath from her already empty lungs. Mewtwo's eyes rolled back in her head as the type advantage worked against her. What might have been a merely average rut was pushing her into one orgasm after another. Already worked up by human fingers, she was twitching and groaning. Gurgling around the cock in her mouth as the brutish length pounded her. Followed by a, "FUCK YEAH, TAKE IT ALL!" as the large ghost slammed into her. His balls leaping as he pumped that phantom seed deep into her. Blasting her cervix, weakening it, and soon overflowing her. Thick, purplish seed drooling down her white thighs and plopping onto the ground.

A whistle, "Well, that's good. How's her stats looking?" Followed by a click, a flash, and the relief as the ghosts were pulled back. Leaving the Pokémon slumping into the bench and shivering. Her eyes rolled back, cum dripping from her chin, down the helmet, and onto the floor.

"Judging from the readouts? I'd have to say well fucked. Certainly going to be compliant for a little bit. Wipe her down and get ready for the next one."

The tech grumbled, but moved around her with a damp cloth. Mewtwo barely twitched, but did let out a groan of protest as some room temperature water was shot into her trembling pussy. Flushing out the Gengar's load and leaving her feeling strangely empty. The numbing remained, cycling back and forth between that tingle and a low warmth that circled and paced within her. The cloth wasn't much better. Wiping her down, leaving her fur matted and damp. Uncomfortable to say the least.

"Alright, think she's ready for next."

Chair creaked, "And next is... Eenie meenie, minnie, this one."

Her head rolled, watching as the tech grabbed a ball from a lineup. There was a flash, a whirl, and an oppressive warmth. "Ruffff," the Arcanine shook out and stretched,. Looking from one tech to the other before spotting her. Mewtwo could only hold on as the bench shifted, repositioning her slightly. Hiking her rear just as the Arcanine rushed in, eager tongue lapping at her exposed pussy.

That made her squeak and jump, the techs laughed. "He's eager isn't he?"

Mewtwo felt something else inside her. The change from null to female had loosened her form a little. After the rapid, heavy assault from the ghost types further breaking her barriers and weakening her mind? She felt the Arcanine's presence at her. Each lick transmitted more thoughts and emotions into her. Primal, raw, simple, his thoughts were focused on one thing. "Smells good. Smells needy. Female, gonna mount, gonna breed!"

Her body resonated and her weakened will couldn't stop it. The tail sleeve slipped, restrained adjusted automatically, and her body arched. Haunches adjusting from bipedal to something more quadrupedal. Her tail grew thinner, then fur erupted from it into something bushy. Hints of orange and stripes sprouted along her backside. Worse, her pussy changed. The sleek lips ballooned outwards, growing into a thick, dark spade. Heavily swollen and burning with a fire that threatened to consume her. Mewtwo writhed on the bench, trying to thrash. Where the armor touched her, where it suppressed her powers, the changes refused to go. While her upper half remained herself, her lower became decided more like him.

That was something he was all too eager to experience.

With a mere, "Boof," the fire dog launched himself on top of her. Weight came down on her body with a crushing force. Driving the breath from her lungs as his chest crashed off her spine. Heavy paws curled about her waist and jerked back, nails raising welts that made her cry out. Thankfully her hips stopped him, gave him purchase. He pulled himself higher on top of her. She caught sight of one of the camera monitors. Watching with growing fear at the heavy balls and plush sheath that swung between his legs. “Where? Where? Where?”

Frantic, shallow thrusts rained down on her. She felt his cock jab and poke. Exploring her backside, planting little stabs here and there. Thing, searing hot precum sprayed on haunch and thigh. Marking her with his heavy scent as he sought out his target. "Hold on, didn't account for this... Let me just," one of the techs muttered and she felt the bench shift. Pushing her just so, forcing her legs to spread a little further, supporting her as the Arcanine's weight bore her down.

Chiseled tip kissed swollen spade. She felt her breath catch in her throat as he slipped forward a fraction of an inch. Spreading that Y of flesh open. “HERE!”

He slammed in with enough force and vigor to drive the breath from her lungs. Heavy pawns threatened to wrench her from the restraints as he drove himself forward. Not stopping until his bunched up sheath smashed against her spade. Wrecking balls crashed off her thighs and belly.

There was no wait, no hesitation. No sooner had his body touched hers than he was moving. Fast didn't begin to describe it. His hips were almost a blur as they mashed against hers over and over. The male barely moved his body, hardly an inch slid in and out. It was a relief after the Gengar. No full length slams. Leaving her nearly empty before hammering everything back in. He wasn't nearly as thick either. Slender, sleek cock sliding in and out as it spat the searing preseed. The only aggravation was the mental press of "Breed!" being hammered into her with each impact was wearing at her weakened will. Churning a body against a mind that was growing more and more compliant.

Hot breath blasted her neck. Thick drool starting to drip onto her shoulder. He hooked his chin against her and tried to pull himself that much higher onto her bound form. Feet danced and kicked. Claws hooking at her thigh, drawing welts with each slip. She cried out, gasped, and found her hips rocking themselves back into him.

His foot found purchase on her calf and the male climbed higher. Getting that fraction of an inch deeper into her. The mental chant of, "BreedBreedBreed!" battered against her senses. Hitting with the same beat of his hips off hers. Pounding into her core, rocking her and the bench under her. Slick, wet sounds of rutting began to fill the air. Punctuated by sharp calls as his claws or teeth found purchase.

"Listen to her moan. Sounds like she's absolutely loving it. Wouldn't have thought the boys upstairs could have designed such a whore."

Something inside Mewtwo sparked, a little resistance. She clenched her jaws and hissed as the Arcanine continued to rut her. The noise came out sputtering and spitting. Jarred loose with every thrust. At least his cock wasn't that large. She felt some relief there.

Until she noticed how it began to grow. Unnoticed at first. That burning, slender length hammered at her depths. Slipping and sliding through slick walls. Then there was a little more drag. A bit more stretch as he pulled in and out. Her body responded against her will. Growing warmer, welcoming the male deeper. That made him speed up all the more. Hips a blur as they hammered her half-changed form.

The pressure grew more with each passing moment. It wasn't long before she started to feel something else. A strange lump within her newly formed spade. Making the slick, swollen flesh squelch and drip as his hips battered hers. Then the was a steady pulse, a push, against her repositioned clit. Pleasure began to rise and spark again, signaling her altered form to release eggs. Telling it signals that her mind couldn't fully process.

A sharp jab deep in her core. His tip stabbed against her cervix on one good thrust. The Arcanine grunted over her, drool dripping onto her shoulder. Heavy jaws snapped and the male's paws wrenched at her tighter, trying to stuff even an iota more of his spire into her, despite having run out of length.

That tightness at her spade grew more, his knot stretching her flesh wider and wider. Engorging himself within her walls and availing himself of her pleasures. Her hissing resistance turned into a yowling cry as the stretching became too much for her first time. Feet kicked and she thrashed. He snarled, jaws clamping onto her shoulder and wrenching her back again. Scrabbling with the suddenly feisty female under him, not knowing she couldn't go anywhere.

Her world went white again. Lights flashing as pleasure and pain surged up her core. Pain from how large his knot was, how greatly his shaft stretched her, and the way his tip punched through her weakened cervix and nestled in there. Pleasure from the way his knot ground and rumbled against her clit.

Another wrench. A tug. Claws dug into her thighs and fangs threatened to rip into her shoulder. Mewtwo's eyes rolled weakly in her head as she felt it. The flamethrower burst of the fire dog's seed. Thin and watery, burning it's way into her core. Each twitch of his balls met with a pulse of his engorged length. Painting her insides with jet after jet of boiling hot cum that her body could barely withstand.

Surprised, "Oh shit, we forgot about his knot!" Hurried footsteps. Fingers against her bloated spade. She jumped at the feel of it, her flesh tender and sensitive in ways she couldn't have imagined. Even that was enough to set her off, making her peak again as the technicians probed her. "Too late now," the voice was resigned, but not disappointed. "How long does it last usually?"

While the humans spoke, the Arcanine relaxed over her. Tongue hanging out as he drooled over her shoulder. Leaving her wet as he panted, the heat of his body oppressive on top of her. The clack of keys, shuffling of paper, and the Arcanine grunted. Weight sliding off her. Her head wrenched back and jaws tensed. Hissing as the male turned around, his cock twisting inside her. Grinding the tip around her abused cervix, mashing her clit with that twitching knot. "Should be about a half hour or so, according to this." Paper rattled as one tech waved.

The Arcanine wagged his tail as the other tech scratched his head. "Well, should be safe here then. Lunch?"

"Fuck it, why not?"

She slumped against the rig as the techs wandered off, discussing food. The Arcanine stood stock still behind her. Tail waving. Balls pulsing against the base of her tail as he continued to fill her. His knot's devilish drumming kept her racing up the mountain to her peak, cresting it with a gut-clench and shuddering grunt. Only to have her body tumble down the valley and begin the climb again. There wasn't energy left to think. After the ghostly assault on her senses, she'd been left weakened. Pliable. Now this mutt wasn't allowing her any peace. He would constantly shift and shuffle. Pulling at her body and making her cry out. Then he'd rock back and settle, mashing her poor clit with that knot of his. Head hung and body shuddered. Feeling his seed pooling in that new womb of hers.

How could this get worse?

---

"Subject: Mewtwo. Ghost type semen collected from a Gengar has been applied and subject seems compliant. Beginning stress test Zero-Two. Three, two, one."

It was the next day. After the Arcanine had softened enough to slip out, he'd decided to mount her again. Getting a second round in before the techs came back. After which they'd decided to call it a day, sedate her, and put her back in the tank. Now here she was again. They'd injected some of the Gengar's seed right into her mask, forcing her to swallow it or choke. It had the effect they'd wanted, leaving her dazed, staggering. They'd had to help her into the lab and onto the bench. Laughing and calling her 'White girl wasted' the whole way.

So here she was, strapped back down and waiting. Head rolling as that ghostly cum roiled and churned in her gut. A snap, flash of light, and a form sprung from the ball behind her. She rolled her head and watched the cameras as an equine form strode up. Flaming mane rippling in its own breeze. "A Rapidash, really? They're putting her through the paces, huh?"

"Oh just wait to see what's on the schedule today. They'd annoyed after yesterday and doubled down."

Muzzle lifted and bumped her backside, nostrils flaring as the stallion snorted. No sooner did his muzzle touch her rear than Mewtwo jumped. It was like a spark jumped from him to her. Sparking a change that coursed through her faster than one could blink. The mechanical bench groaned and adjusted, reacting as quick as it could. Altering how it held onto her legs as they grew longer, more equine. Moving over her hips as the haunches rounded out and hip bones ground. The tail sleeve was gone today. Not that it mattered as her tail shortened and hairs burst into flame. Her pussy and body changed again. Adapting to the male behind her faster than she could think. Those deep purple lips grew lighter creamy in color. Inner walls flushed a fiery red as a new heat flashed though her. Hotter than even the Arcanine form had been. She felt a tremble in her core, an off flex. Saw how her newly shaped lips flexed and pulled, clit rolling out in an equine wink.

The stallion snorted in surprise leaned in, and breathed her scent again. She felt curiosity as his muzzle bumped her. Body reacting with another wink, adding a gush of fluid this time. Which made the stallion dip his head, then lift it, lips flaring out as he breathed.

"Ah fuckin... All over the floor!"

"Maintenance will get it. Go get a mop if it bothers you."

Sparks of flame burst from the stallions nostrils as he snorted. Out of the corner of her eye, she could see the camera view. Watching as his manhood dropped from his sheath. Began to swing as it firmed up, lifting higher and higher until it hit his belly. Worry surged up Mewtwo's spine. That must be longer than my arm, can't tell how thick either.

Another snort, a flurry of embers rained off her backside. The somewhat fireproofed flesh withstood, feeling warm but little else. Muscles shuddered and she tried to buck and kick. The restraints held tight as the stallion snorted again. Then reared, prancing on hinds for a breath before his chest slammed into her haunch. She breathed out a grunt and watched with mounting worry as the male drug himself up her rear. Forelegs fumbling at her sides, trying to grip as the Arcanine had. All while his hooves sparked and danced off the tiled floor.

Pressure as his tip found her entrance. A wink flexed her flesh over his. Spreading the walls against the tip, feeling how the flare nestled a touch deeper. He grunted at her, hunching over her body. Powerful, flat teeth clamped onto her shoulder and pinched hard enough to make her cry out and flinch. The stallion hunched and drove himself into her.

Even with her larger form, that first thrust was enough to drive the breath from her lungs. Mewtwo grabbed at the armrests, pulled, tried to kick. _ "Breed." _ the presence grunted over her. Drawing back as his cock shuddered inside her. Tight, barely prepared walls trembled against his might. A loud, wet schlorp sounding in the lab before he slammed in again. The pressure of his cock driving into her made an even more lewd noise, a thick, wet noise as he pounded himself in.

There was some luck with her though. Either the scientists didn't know, or hadn't accounted for it. Rapidash, like many Pokémon of his type, weren't made for marathon ruts. He managed to get in one, two, three thrusts. Each one hard enough to rock the female under him, threatening to overturn the bench she was bound to. She felt him trembled over her. That bulbous tip of his cock swelled, flaring against her insides. Then a fourth and final thrust.

The Arcanine's seed had been hot. Thin, blazing seed that pumped into her continuously for the entire time they'd been tied together. It had left her feeling warm, almost feverish, for hours after.

Somehow, the Rapidash's semen was even hotter. Thick, molten magma that blasted her walls. Plastering her with heavy, thick spunk that quickly filled her to overflowing. Stomach bulging against the restrains, getting compressed. His cum fought against the thickness of his flare before leaking out around it. Her thighs shook as the male took a couple shallow, grinding thrusts. All before softening within seconds and sliding off her.

His cock came free with a thick, wet plorp. Her thighs shook and tried to clench as she felt the sudden vacancy, followed immediately by a small torrent of his cum pouring out of her body. Dripping onto the floor in heavy, clinging strands. The stallion slipped back, but kept his head on her haunch. Panting heavily, eyeing the technicians.

"Huh, thought he'd last longer."

A dismissive, "Told you. Now go get the mop, I'll put him away."

She had a moment of reprieve. Body slowly sinking back towards her natural, or rather, engineered, form. Insides quivering as that melting heat stained her insides. Leaving her trembling and sweating as the technicians cleaned her and the floor up. Scooping almost as much as mopping.

The moment wouldn't last though. "Next subject. Hey, look at that one. Guess they're really trying to test her out, huh?"

She was breathing hard, trying to regain control of her mind and body when they released the next male. A familiar flash, whine of the poke ball, and then a thundering step. A gray mass moved in front of the camera, almost blocking the view. What felt like a heavy hand fell onto her haunch and her body reacted. Tail all but vanishing. Her hide became thick and gray, yet somehow still sensitive as the touch wandered. "Rhy... " came he low rumble in a voice that shook her to the core. "What do we have here, freshly fucked just for me?" The rhydon moved up behind her, rubbing the tip of his semi-hard cock against her body. "They shouldn't have…"

Mewtwo's body was still adjusting when he pushed in. That half-hard cock easily as thick as Rapidash's had been. Her cum-coated insides clenched, squelching wetly as he pushed deeper. Rocking his hips ever so slightly as his flesh pulsed. Growing harder and harder within her withe each moment as her body scrambled to adapt. Yet even her abilities told her that this male was big, larger than most of his species.

"Urrrgaa," she couldn't help but groan as heavy hands fell to her hips. The Rhydon rocked his hips back, then slammed forward. "UGH!" Mewtwo barked and threw her head back. Hard, deep thrusts came down on her rear. Starting slow, then picking up force, speed, and ferocity. "UGH! ARRGH! UGGGN!" Her breath was knocked out of her body. It was like trying to withstand an avalanche.

Then there was the shape of him. A spiral tip drilled into her core. Winglets on the side of his cock rubbed and ground against her insides. Balls the size of boulders crashed off her thighs and body. All while his hands fumbled and felt over her hips and sides. One even going so far as to dip below her to play with her clit. "Rhydon…" came the pleased sigh. "I fucking love those noises you're making, Sweetheart. Gonna make me cum if you keep that up."

Some rebellious part of her clamped her mouth shut. Hisses blasting from clenched teeth. "Don..." he rumbled "That's not very nice is it?" The next thrust coming with enough strength behind it, she heard something snap. Her entire body rocked forward, shook, and nearly fell to the ground. The tip of that cock pounded her cervix, pried at it, and she couldn't help but cry out. "Rhyhyhydon," he smugly rumbled. "There was that too hard?"

An alarmed, "He broke the bench!"

"Do you want to stop him?"

Hesitant, then a, "No, but someone's gonna be pissed about it."

A laughed, "Let'em, it was their idea. Where did we get this one anyway?"

“Some trainer had it around Route 7. The guys got it there.”

Mewtwo knew. While the humans were chattering, she felt the Rhydon's presence pushing at her. With each grunt, he filled her in."Always loved fucking fire types. Had gotten my claws on this Rapidash mare. Got to her just after a stallion had her. She was still hot and dripping, just like you. Mmm, I can feel a stud's gift inside you." He slammed his hips against her, and ground. "Thick, warm, feels like it's gonna burn my cock off. They might buck and struggle a little, but once I start working them. Once I start doing this..." a thick nail played with her clit and made Mewtwo squirm and jerk. "Isn't long until they're begging for more."

He was skilled, he was good at this. Even her limited experience told her that much. Though Mewtwo hadn't had much beyond the two ghost types, and the more animalistic fire types. She felt her pleasure building. The Rapidash had barely even stoked her fires. Now here she was, trembling and pressing, body working off instinct and the male's unspoken desires. A deep, empathic ability of hers reading him and responding faster and quicker than her added brain could think.

She squealed as she came around him. Trembling and shaking, thighs quivering as juices squirted around his cock. "That's a good girl." He leaned forward, one hand curled around her waist, the other moving up to grab her breast. "That's one. Wonder how many we can get up to." His tongue brushed her neck and swept under the helmet as he rocked. Only her transformed haunches kept her up. "I can go for a while..." came the casual threat. He shoved forward and ground, his tip drilling through her cervix. Making her insides clench and shudder, calling out again.

She lost count after six.

"Rh...rhydon!" Hands grabbed at her hips and wrenched her back. Another deep slam, his tip easily drilling past her cervix and into her womb. The first shot hit her like a glob of concrete. Thick, almost gritty as it slammed into her poor womb. Making her stomach bulge with the first shot alone. Then came the unexpected as he pulled back. Wrenching his cock out of her body and stroking it. Her head lifted weakly. Armor knocked off, helmet askew, but helpless on the floor, laying on her side. The male stroked himself and coaxed out shot after shot of thick cum. Painting her belly, breasts, and thighs with his essence.

"Rhy," he breathed. "Not my best showing, but they were starting to look impatient."

On cue, "Finally! That was almost two fucking hours. Look at his face, the smug bastard is proud of it too."

"Rhy," he smirked. "I did hurry it along. Can sometimes go all day." He watched as the techs got his Pokéball. "No hard feelings, it's all part of the gig. You ever get out, release me and I'll give them a taste, hey?" A look, "That one is kinda cu…"

Then he can as gone in a flash and she fell back to the floor. Body shaking as it slowly reverted. That heavy cum refusing to shift as she slimmed back down.

Grumbling, "That threw all the testing schedule off. Not to mention the damage to the equipment."

A pause, "Well, push it forward. Get the next one. Don't bother to clean her up. If they complain, we just retest.

Next one will keep her calm, or should. Then we do two again right after."

The tech looked at his partner, "Fine, whatever. Next is... This one."

"Hold up, the ones given trouble in the past. Gotta hit him with a bit of this." The tech handed over a bottle. The first one took it, stuck it against the Pokéball, sprayed, and waited a moment before hitting the release.

A Scyther appeared in a flash of light. The insect looked from her to the Techs, and back. The male looked powerful, muscles sliding under fur and chitin. The bladed arms looked sharp, dangerous. And between his legs? A throbbing cock, deep red, bulbous tip, and sharply pointed ridges along the underside. As she watched, the flesh throbbed, pulsed. His nose twitched and the Scyther shuddered.

Then advanced on her. Blades scratched at the tiles as he leaned over her body. "Scyther..." he growled as he touched, pushing her down with his body. "... Can't help it, the pheromones...barely think... I..." the thoughts were sharp, fragmented, and laced with chemically induced lust.

His cock dove into her as the male growled. Blades scraped off tile as he drove himself into her. Mewtwo jumped, yowling as the insect cock drove into her. A body, still trembling and recovering from being rutted and made to climax over and over. Now it bore down on another male that her very nature was weak against. He buried half his length with the first push.

Lights flashed before her eyes as he pulled back. Those ridges dug into her insides and grasped back. She gasped, might have thrown her head back, fought to stay conscious. A rush of cum and fluids ran down her thighs as his length drew back. Scooped out by the ridges. He growled dangerously, lunged, and caught her neck with his teeth. The male pushed in again. Burying himself to the root this time. His tip smacked her cervix. It would had glanced off, but her muscle was battered, broken, the barrier destroyed enough to let him inside. A breath of pressure, a pinch, and his tip surged into her. Sliding deeper than she would have thought, driving the breath from her.

A shiver. A growl. The deep, primal snarl of "Another male has had her," pressed against her senses. All while his hips ground into hers. Furiously mashing his groin against her, hips flexing madly. Muscles quivering with chemically induced need.

Then something that made her eyes widen in shock and surprise. His bulbous tip twitched inside her, then felt like it opened up. The Scyther buried his nose against her neck and growled. His teeth scraped her neck as his hips kept rolling. In her current state, she couldn't begin to imagine what it looked like or what it was doing, but she could feel it. It flexed and curled, brushing the front of her womb. Her stomach pushed out as he rolled his hips then pulled back. Ridges scraping her like a fleshy saw. Ridges like teeth hooking and grinding, sending stimulating waves through her aching body that had her eyes roll back. The tip pulled at her cervix then popped out.

Next thrust, pushing so deep into her. Tip opened again and scraped at her insides. However, this time when he pulled out, there was another gush. Thick, heavy globs of Rhydon spunk forced out of her. Scooped out of her womb, escorted down his shaft by the flexing, rolling ridges, and expelled by his retreat. Another thrust, his cock stretched! Tip punched through her ruined cervix and scraped the back wall of her womb.

Within a few thrusts, the scraping and grinding set her off again. Mewtwo's eyes rolled back until only the whites of her eyes were visible. She moaned, or she thought she did. Perhaps it was just the defeated groan of air being wrenched from her lungs. She didn't know, couldn't know. Her world devolved into sharp, almost painful, pleasure.

Bladed forelimbs smacked off her hips and body. The flat of the natural weapons cracking off her hide before hooking with expert precision. It scratched like the Arcanine's claws, but held on. Forcing her around until her belly was flat on the floor. Breasts mashing into the icy tile, face getting pressed down as he forced her hips up. Legs splayed out limply from either side.

Pencil on paper, "So, do you think that she's run out of the energy to change, or do you think it has to do with the type advantage?"

Fingers appeared at the edges of her vision. The tech pulled her helmet off, "I'm not sure, but look at that face! That's about the definition of fucked senseless isn't it?"

Mewtwo would have hated to admit it, but he was right. Her mind was a whirl of static. Psychic powers shorted out and fed into a feedback loop that had her in a daze. The Scyther's raw lust pressed against her. Crushing any and all thought. While his cock stimulated her body in ways that it wasn't designed for. The pattern of thrust, scrape, and scoop doing things to her that she couldn't fathom. Thick fingers scraped against the floor, trying to find some sort of purchase. Or were they simply looking for something to grab? She didn't know, she wasn't even sure if she was in control.

A snarl, a flash, and a yelped, "Fucker almost cut me!"

The other tech chuckled, "You're the one that dosed him up. He's in full protective rut mode. See the posture? He's saying that she's his and back off." Chair creaked, "You know, I'd heard that a male Scyther has ways to remove a rival's semen from a female. Never imagined it'd be like that."

Hips crashed off hers as the bug type worked. It felt like he was trying to hollow her out. The cleaner she got, the more frantic his thrusts became. He pinned her to the floor with his weight. Pressing her down with a growl before his mouth found her neck again. Teeth biting and pulling as the primal chant of, "_ Mine, _" droned against her. If it went too long, pressed too hard, it might very well condition her to believe she was merely his.

Did she climax? She really couldn't tell. Her body was leaping between icy, on fire, and charged with energy. It'd clench and shudder in one moment, then spike with other sensations the next. Thankfully the spray the techs used took some of his self-control away. If he'd been in charge of his facilities, he might have pressed that advantage. As it was, it was only a few moments more before he pressed against her. Burying a snarl into her neck as his claws dug into the tile. Teeth dug in and he snarled. Cock spearing as deep as she could take it. His hips shuddered, lifted, and then he hunched. Ridges giving one last flare, trying to seal her abused body around him. Then she felt the pulse as it raced up his length. Spurs pressed out one by one, digging that much deeper, before the tip flexed and planted his first shot right into her womb.

Panting growls died into a low, purring snarl. The male slumped against her, as spent as she was. His cock giving her everything he had, making her belly swell ever so slightly. Thick, heavy cum staining her thighs and dripping under her belly.

Then, with a flash and whir, he was gone. "Get the mop. I'll get her up and settled on something." A sigh, "You'll probably have to get some of the stronger cleaners for that Rhydon."

Followed by a grumbled, "Why do I always have to get the mop?"

"Consider it a ten minute break. Cameras off, get a snack, and come back."

Her head rolled as the cameras clicked off with a series of chimes. While one tech went 'to get the mop' and take a break, the other picked her up. "Look at you, absolute mess. Good thing we've got a spare bench, but it's not near as fancy." The spare bench was little more than a long, padded surface with some adjustable legs. As the tech laid her on it, belly down, he looked towards the door. "Gonna take a few minutes to get back here..." Her head rolled, mouth open as she tried to steady her breathing. Her mind was still scrambled. The fucking and the lingering insect cum was shorting her out. "Watching you get hammered got me all worked up," he breathed and unzipped his pants.

Out came a rather plain cock. Uncut, average for a human, and throbbing. Her nose twitched as he leaned forward. One hand came to rest on her head, "Too out of if, I guess," he chuckled and smacked his cock off her face. "Doesn't matter too much, I find." He sighed with delight as he pushed his tip into her mouth. Mewtwo groaned, tongue rolling to push at him. He took that invitation and pressed past her tongue, fangs framing his length as he sighed, "There we go. Just gonna make this quick."

He wasn't nearly as long as Haunter, and she hadn't had any other males in her mouth. The tech held onto her head and casually began to rock his hips. Grinding his length against her tongue. Letting the foreskin pull back and glide over her tongue as it arched and rolled. "There you go," came the breathy moan. One hand reaching down under her to cup her breast. "That's a good slutmon." His fingers were rough, awkward. Groping and pinching her flesh. Fingers squeezing her teat hard and bringing it to sharp points before rolling it between his fingers. She might have moaned, perhaps even whimpered, but he didn't seem to care.

Hips rocked smoothly against her face as the human knelt before her. "That's it, suck on me like you know you want to." The hand on her breast moved and slapped the swaying mound. She grunted under him, muzzle wrinkling. Her eyes rolled and just managed to focus on him a little. Watching past that cheap shirt and open coat. Thrusts came faster, more and more shallow. Precum spilling over her tongue

It was only a moment before, "Here it goes!" as he pulled back. The hand on her head moved to her mouth. Thumb hooking into her cheek and wrenching her head up. Mewtwo tried to snarl, but the noise only came out as a useless sigh, tongue dropping from her mouth and rolling against his finger. He grabbed his cock and stroked it. "That's it, give me that eager face!" A few strokes and he was done. Cum leaping from his tip, raining down on her face and the mouth he held open. She tasted salty cum spread over her tongue and had to close her eyes. "Fuuuuucking hell," he breathed and shook his cock. Smacking it off her face to get the last out. "I needed that. What a good kitty cat you are."

One last smack of flesh on her face then he stood up. Cleaning himself with a cloth. After he tucked his cock away, he took the same cloth and began to wipe her clean. Which is what he was doing when his coworker walked back in with drinks, some smacks, and the mop.

Their cleanup and chatter gave her some time to recover. Not much, she could feel her powers jangling uselessly around inside her head. Pinging off her nerves and senses, still scrambled by the bug. It did give her time to think though. Explore the new power she'd been using the last couple days. That strange shape shifting ability. Keeping a hand low, she looked at it and focused. Drawing her willpower to it. As she thought and pressed her will, she could feel her body twitch. Flesh start to rearrange as she willed. Fingers growing thicker, gray, heavy, like the Rhydon's digits.

"Okay, about as good as we'll get." She moved her hand and reverted it. Rolling her head as if still bug-drunk as the techs returned to the desk. "Wanna get the last two at once?"

Confusion, "Why two at once?"

Snacks crunched as he popped something into his mouth, "Well, I figure either we'll get to wrap it up early, or and this could go into the notes. We can see if she might turn into a hybrid, half and half, or if she's got a limited amount of times she can alter herself per rest."

"Eh, good enough for me. Here, give her a spray of this."

The face-fucker caught a spray bottle, "Ah yeah, Heateon spray."

"Not what it... Know what, never mind. Just give her a spray."

While one got the balls, the other gave her rear a couple sprays. Then smirked down at her and gave her a shot across the face. Mewtwo winced, hissed, and the scent of something else flooded her senses. Nothing she could readily recognize, but it was probably some sort of pheromone.

Twin flashes, nothing unusual, she was getting used to them deploying Pokémon. This time, however, she was in for a little bit of a surprise. Two Pokémon. One bright yellow and the other a cooler blue. A Jolteon and Vaporeon sniffed and looked around before padding at her. Her head rolled as both made a beeline for her backside. Cold noses and warm tongues probed at her, followed by a zapping snarl and snap of jaws. The Vaporeon let a growl bubble up, but backed away as the Jolteon immediately started to lick her pussy. Mewtwo groaned, her hips arching, twitching as each lick sent shudders through her overworked slit. Worse was the strange tingle that began to build with each lap. Not pleasure, more like static charge.

Her fur began to stand on end as the charge steadily built. Then release with a small pop that made her jerk and gasp. Electricity leaping from her to the departing tongue. Arcing from damp lips and swollen clit to eager maw. Which made the male behind her churr and chitter happily. Giving her rear a bite before lurching to his feet and mounting.

The Vaporeon was far from idle. It wandered around in front of her and began to sniff. Her head rolled and she spied its... Slit? Fleshy slit swelling, then opening to expel a tapered cock and balls. Thick, swollen and growing heavier, swaying under its body. Balls churning and full, ready for a rut it had been denied by the fellow eeveelution.

Except it hadn't been fully denied.

This had to be what Face Fucker had been hoping for. As the Jolteon drew himself on top of her, the Vaporeon reared from the other side. Forelimbs grabbing at her shoulders and armpits as the other male grappled her hips.

"Little short, lowering the bench." The tech nudged a lever and the bench dropped a couple inches. The two Pokémon males growled and grumbled, but pulled themselves higher into her. Nails scratched and scrabbled at hips and ribs. She growled, the noise weak and wobbly. Neither male cared as they rocked their hips against her. Claws dug and hunched. The Jolteon pressed tighter, cock sliding against her backside, precum spitting over her fur, all while growls sparked and snapped against her. Up front, the Vaporeon was in a similar boat, but seemed to have more restraint. Taking his thrusts slower, grinding up and forward. Tapered cock sliding over chin and cheek as she rolled her head away.

Chiseled cock glanced off her outer lips. As the Jolteon scraped past her, his precum sparked and shocked her. The psychic type gasped at the popping, sharp sensation. Which was more than enough for the Vaporeon to strike. His cock twitched as it probed her face. Then it flexed on its own, thin tip slipping across her lips, into her mouth, and finding solace there. The watery male growled and pulled sharply, driving his groin into her face and burying his cock there. Mewtwo wrenched and tried to pull back, but he had too good of a hold on her. Hips mashing hard and fast against her muzzle. Cock sliding across her lips, past her tongue, and right into her throat. A low, primal growl slipped from his maw as he surged over her. Hips mashing her face hard and fast, balls clapping off her chin.

Not to be outdone, the Jolteon found his purchase a second later. Tip slid across her lips, just caught at her abused entrance, and pushed in. Precum shot against her insides, leaving a sizzling, tingling where it stained her insides. Hips crashed off hers as the male pulled himself as deep as he could go. Sheath pressed tight to her body as he began to rock his hips hard and fast.

Her experience with the Arcanine had prepared her for the incredibly rapid, shallow thrusts. Though it hardly prepared her for having her face and throat stuffed with a cock. Her hand came up and braced against the Vaporeon, arm trembling as she tried to gather the strength to push him off. That only seemed to encourage him. A snarl bubbled up and he redoubled his efforts. Cock plunging down her throat and leaving her nearly gagging with each push. She expected his precum to be thin and watery, and it was. At first at least, but then it seemed to grow thicker after even a second of lingering in her mouth or throat. It coated and clung, forcing her to swallow or choke on it.

Likewise, behind her Jolteon was having the time of his life. Not as fast or as strong as Arcanine. The constant zapping and sparking as their bodies met and pulled apart was starting to stimulate her in new and strange ways. Her body clenched, shuddered, and soaked his length. Letting him slide faster, building up charge like a sexual dynamo. Each thrust was met with a tingle as he impacted her, a buzzing, and then a sharp electric pop as he pulled away and arced off her. Toes flexed and curled, the psychic's eyes rolling around as she grunted under the males.

As with the Arcanine, neither were made to last long. It was mere moments before she felt the Jolteon's knot start to grow. Popping against her body as it grew larger and heavier. Stretching a pussy that, unlike the spade she wore for the fire type, wasn't wholly made to grasp him. Yet still, she could feel it start to catch as he dug deeper.

Though worryingly was the Vaporeon's knot. Her eyes widened as it began to push and roll. Like his precum, it sloshed and rolled a little. Then began firmer and firmer with each moment. Becoming almost gel-like, then hardening. Paws pulled at her shoulders and chest, hooked and wrenched at her body. His knot slid past her lips and jaws. Drawing out panicked gagging noises from Mewtwo. She jerked her head and tried to pull away again. Only to receive a harder thrust. Knot grinding at her lips, forcing her jaws to stretch wider and wider. She felt hot tears gathering at the corner of her eyes as his knot forced her mouth to stretch further than it ever had before.

With a wet, sticky pop , his hips crashed off her face. Nose buried into his slit as the male hammered. Knotted length continuing to stretch her jaws wider, bulge her throat around his length as it pressed deeper. She could feel his shaft pulse and slither. Making her throat flex as it slid back and forth inside her gullet. All while his balls began to tighten, pulse, then unleash a tsunami of water-type spunk right down her gullet and into her gut.

Jolteon wasn't far off. His hips crashing off hers, making her peak and tremble as electricity popped and crackled off clit and radiated against her g-spot as he hammered her. That knot managed to catch and hold inside her pussy. Not as tight as a spade, but he didn't care. Teeth found a spot to bite near her spine. The male arching as he snarled. Tip pushed through her cervix before planting the thunderous seed deep in her. Making her entire body light up as he set off a charge against every nerve within her.

Pulse after pulse, throb after heave, the pair began to fill her mouth and pussy. Electricity arcing off where he met her, and where her body met the bench. Stomach bulging, sagging, as more of the thick, heavy seed filled her belly.

"Well, look at that." Face fucker laughed and walked around her. He reached down and felt her cheeks, "Yeah, he's knotted right in there. Wonder if it feels better than a bitch." Even without him squeezing her cheeks, she knew she had to look quite the sight. Every pulse of the knot made her cheeks bulge, jaw lower, and fangs hook behind that bulge. Each throb made her throat swell before the shot added to her already sloshing, churning stomach.

The Vaporeon grunted something and slid off her. Twisting around, making her jaws flex and distend as he turned. Not stopping until his balls rested on the bridge of her nose. Filing her vision as they twitched, adding one shot after another right down her throat.

"Probably a good time to do paperwork. Let the boys finish up, we log all this, and tada. How's she looking?"

Her eyes rolled back as the tech moved the male's tail. "Oh she's properly out of it." The fluke came down and smacked off her head. Mewtwo made a face, righting her eyes to watch as the human walked away. Insides still quivering as the Jolteon twisted as well. His charged semen tingling and tickling her insides. If they were any thing like the Arcanine, this was a half-hour wait. Plenty of time to recover.

"PHfraaaaa!" Mewtwo gasped as the Vaporeon slipped out. Head low and body heavy as the thick, heavy cum started to drip from her mouth. Hanging in heavy strands as she gasped.

That was enough to draw Frank's attention. "Ah good, she's free."

Mark sighed, "Wonder if we should have gotten the males away while they were still tied."

A pause and hum, "Would they still be up and swollen once they're out again? Does the ball pause them or do you think that…"

_ "ENOUGH." _

The telepathic voice froze both techs as Mewtwo lifted up. Her willpower crashed down on them and pinned their minds, freezing their bodies in place. "I have had enough of this!" the mental voice rang out as the genetically engineered psychic rose. Jolteon falling out with a yelp and scampering away. Her eyes glowed with a fury as she arched her head and rolled her neck.

Pushing her will down on herself, she began to reshape her body. Breasts shrank and retreated, forming into toned pectoral muscles. Cum boiled off her pelt and away from her form, turned into raw energy as she turned herself into a male. "You have taught me what you think of females. Where you believe they belong in the cycle of things. So I think I will adopt a male form for what comes next." The voice deepened as his body changed and reshaped itself.

Mewtwo held out a hand and pointed it at Frank, "You sought pleasure from my female form. So perhaps I should start with you." A twitch of his fingers blew the lab tech's clothes off. "We shall start simply, shall we not? Breasts, hips, and genitals." Matter was matter, genetics were simply code, and they had taught Mewtwo how to alter that with his own mind. Frank could barely gasp as his body twisted and changed under the Pokémon's willpower. Breasts all but erupting from his chest, hips widening, and penis shrinking away into a new vagina within seconds. "Now you," he looked at Mark, "bring out the Rhydon from earlier. I wish to conduct some tests of my own."

Panic rose in Frank's eyes as Mewtwo pointed at the ruined bench. Metal twisted and reshaped itself, "Come here." Her body shuffled, muscles and limbs moving as Mewtwo imposed his will. "Knees here." Straps and metal moved, securing the tech down. "That's a good slut. Start recording. Stress tests, mark two, trial zero one. "
