Dr.K and Mei become lab partners

Summary:

After heroes destroyed Dr.Ks facility, he was forced to U.A labs, decoding a quirk-erasure serum or face life in prison for his crimes. Dr.K regrets it after he realizes he will be spending time in the Department of Support with a sorry excuse of a chemical lab and the person watching over him doesn't even understand basic boundaries or personal space… Mei Hatsume!

Leading to very scandalous interactions…

Notes:

Oh boy... odd pairing I know, but I couldn't get the idea out of my head

Chapter Text

Dr.K had only been in this lab for 30 minutes and was already regretting it.

Mei Hatsume pressed against him before shoving another one of her 'babies' in his face. "You’ll love this one! It's a specialized grappling hook I made but it's currently just a prototype!”

Dr.K sighed, one of a dozen sighs he's already made.

Oh yes he sighed. With the feeling of every cell in his body coiling into itself. The cobbled-together transfurred serum he had been fiddling with unceremoniously dropped from his hands once his sensitive ears picked up that all too familiar voice he had been hearing for the past… half hour!

“Mei,” Dr.K acknowledged her presence. Not unlike how a child would acknowledge a dentist moments before having their mouth drilled into. “You don't have to show me every invention you've ever made. I understand you are intelligent.”

“I'm not done showing you but okay.” The chipper girl smiled. Her distinguishable reticle eyes locked onto his red ones that were behind the gas mask. “The top heroes put you under my watch. So I have to ‘watch’ what you do. So what are you doing? Something unnefarious I hope.”

‘Go away’ Dr.K narrowly skirted from blurting out as he shook his head.

“I'm seeing how the quirk eraser dart reacts to transfurmation cells.” He half spoke, half sighed. His displeasure went largely unnoticed by Mei.

Placing it under the microscope. He trained that skill of being able to recognize whatever manner of complex chemical bonds that required his equally complex intellect. Dr.Ks encyclopedic memory of his utensils saved him the trouble of trial and error when it came to ideas like this.

If only he was able to shave off the time he’d have to spend listening to-

“So how are they reacting?”

“They aren't…”

“Is that good?”

“Not exactly.”

“What are you waiting for?”

He felt his red eye twitch in irritation “A reaction.”

“You aren’t gonna say more than two words huh?”

The genius annoyed hybrid dismissively turned the knobs on the microscope to get a closer look, his large white feline-like ears swiveling towards her then going back down beside his head. “No talking, please.”

“Sorry, sorry,” Mei’s lively attitude didn’t miss a beat. “I know how much you science guys love your peace and quiet, funny how our stations are right beside each other. My stations the loudest here!”

“Hm.” K wordlessly grunted as he allowed himself to go back to his work. He was impressed that the transfurmation cells he had access to were still functional enough to try and absorb the quirk eraser serum. Maybe if he added more it would fully absorb-

“Say, I made an invention that sees how dense someone's neurons are. Can I test it on you?”

The hybrids expression soured, if his annoyance could even get worse. “In a bit. Im busy”

“It took a day to build!” She said while sliding her computer closer to them both, she was pressed up against him feeling her large breasts press against him, he nudged her away in annoyance. “I lied, it actually took a few hours!”

“Riveting. Move, personal space Mei.” K grumbled.

Mei did what she was told, moving an inch away or so. Though her spiel continued regardless of whether or not she acknowledged his disinterest, her fingers typing away.

“Honestly Dr.K I want to know what your mind sees, the heroes want you in here for some reason. Even though they destroyed the facility you were in. You must've been doing something terrible for that to happen.” Mei narrowed her eyes at him as he continued to jot down chemicals reactions. “I bet they either said you could rot in jail or be with me in the Department of Support! And you're our first and only bioengineer scientist!”

For once, Dr.K found himself pining for Shota Aizawa’s impeccable ability to completely dissociate from reality and fall unconscious in seconds, however the hell he managed to pull that off. He was special that way. Hypersomnia or narcolepsy perhaps?

Her bubbly voice pulled him out of that thought. “But fine both you and the heroes won't tell me so ill stop asking about it,” She said in defeat. Dr.K mentally sighed in relief. ‘Thank every higher power.’ and went back to jotting notes. “So… why do you have that gas mask on?”

Dr.K’s better judgment begged him not to dignify that with a response for the sake of preserving what little was left of his peace of mind. It was times like this he wished he didn't have an IQ of 180… ignorance would be bliss right now. But he opened his mouth anyways

“My sense of smell was heightened after-” Dr.K started.

That was the inch.

He didn't even get to finish his sentence as Mei took her mile, and practically tore his mask away from his white furred face. “Wait! I can add some modifications to this!”

Feeling the air hit his fur, a feeling he hadn't felt in forever, he growled and went to snag it back, claws unsheathed. “Hatsume, give it back! You-” Autonomously without thinking, he breathed through his nose… and immediately regretted it. Recoiling. He could smell everything in the room, intense industrial chemicals, soldering fumes, burning metal and the one that was the most intense MEI! Her scent and body odor was overwhelming.

Slamming his paw over his snout he started breathing through his mouth “Jesus Hatsume, you should practice better hygiene!”

“What? I shower once every week, plus it can't be that bad.” Mei mused, chuckling to herself as she applied different software and hardware to his specialized gas mask in record time before throwing it back to him.

He immediately put it back on and breathed a sigh of relief as it hissed from pressure, he then narrowed his red eyes at her. “If you do that again, I will… destroy everything you have ever worked on”

Mei didn't take his threat seriously, smirking. “What? Don't lie, you probably enjoy how I smell, you're a fluffy dog right!? A good lab boy! How could you not?” She pointed a finger at him teasingly.

“How insulting…” Dr.K quickly turned his head from Mei at the slightest sense of heat rising to his fluffy cheeks before going back to his work.

Despite his valiant effort at keeping responses terse enough to kill the discussion completely, Mei was undaunted.

“So what about your ears?” Dr.K sighed and gave up doing tests on the serum, dropping his equipment in despair. Given how her own ears conveniently didn’t hear his simple order from earlier to hush, he didn't think repeating himself would do anything different. He'd be justifying the definition of insanity if he tried. “Hightened senses include your ears right. You don't seem to need earmuffs!”

K rolled his red eyes pensively. For someone who reported directly to the upper brass of heroes and was actually smart, Mei showed a remarkable amount of obliviousness. “Yes Mei, that includes my ears, it includes everything. Once I transferred I gained what you all call a quirk. My senses are so heightened that it's distracting to do normal tasks without my mask. I also have a sort of 6th sense, I call it precognition… Does that answer your question?”

To his surprise, Mei nodded and went silent. Thanking whatever god was still out there again he leaned forward to run more tests… for a solid 2 seconds, “That does answer my question but now I want to know what happened after they brought you here?”

He scoffed and leaned back in the chair, giving up on continuing his work. “Why would you want to know that?”

Unfettered, Mei rested her head on her arm while she pestered him. “Well if we're going to be working with each other then there are no secrets. Plus I have to watch you now, so I want to know why.”

Deciding saying no wouldn't work he gave in. “Fine.” Dr.K started reciting what happened, He remembered every detail with his photographic memory. While leaning forward to at least attempt to continue his work.

Detective Naomasa Tsukauchi sat in front of Dr.K. With Aizawa beside him, glaring daggers into the hybrid. His hands cuffed to the table. “You call yourself… Dr.K? You have been Extradited to Musutafu and are currently charged with unethical experimentation, kidnapping, and reckless endangerment. No identity, no background, no former family. And because of your fur… no finger print. Blood samples also turned up nothing. Yet you are the best bioengineering scientist that we've ever seen. After raiding your facility, you've done thousands of tests with years of research that could've went to saving lives? Yet went towards this pale virus that didn't exist, and all the unethical experiments.”

The scientist glared at them, not giving them an answer. His years of work was going to be taken by others and plagiarized. Disgusting…

“Not talking? Fine, we'll skip that and just ask you this.” Suddenly he placed what looked to be some sort of modern dart on the table in-between his hands. “Once shot at someone it erases their quirk, we need an antidote, this is the only one we have that was a dud.”

Hmming Dr.K took the Dart studying the bright red device. “Hmm, a needle tip designed to inject the drug directly into the target's bloodstream. Standard…” After inspecting it for a few more seconds he placed it back down. “I have no idea what this is. But fine, I'll need a lab to test this and figure this out, but what's in it for me? I'm not very enthusiastic about doing this after you all destroyed my life's work.”

Naomasa raised an eyebrow and scowled. “Whats in it for you is that you won't spend life in a cell and we drop the charges. But keep in mind you will be under constant surveillance and there are at least 40 heroes in the building you are going to be in. So you better not try anything”

Dr.K leaned back, Looking up at the bright light that illuminated the room, he felt naked without his mask but oddly enough he hasn't been able to use his heightened senses, since that guy with bloodshot eyes walked into the room. “Look I don't need the details, I'll do whatever you want me to do. But just where will I be”

That's when the other male spoke up. “U.A high.”
—--

Dr.K impressed himself a feat that occurred far less frequently than one would think. By the time he finished his story, he realized he was all but finished with his notes. Interesting, if not remarkably concerning.

Not as concerning as the realization that Mei was now talking right through his ears, chattering away and unable to tell that her “listener” had tuned her out the entire time. At least now, he learned that he could tune her out.

“You know those are some very serious charges But I have faith that you'll find out the chemical in the dart and get them dropped.” Not unlike a prying sibling, Mei still kept on the topic. “Maybe even become a hero someday. Oh! I need to get your measurements and analyze your physical build and movement patterns for creating and testing new babys!”

“Measurements?” Dr.K started with a raised eyebrow under his mask, he didn’t like a lot of things. He most certainly didn’t like the sudden tease mingling in her voice.

She was faster than his fight or flight response as he felt his fur puff up instinctively, a defensive mechanism. While her hands felt up the muscles underneath his lab coat. Mei's palms slid boldly over his broad shoulders, squeezing the taut biceps that strained against his sleeves like she was appraising a prime cut of meat at the market. "Whoa, these are solid! You're built like a tank under all that fluff, bet you could bench-press almost 200 no problem!"

Dr. K froze, his red eyes widening behind the gas mask as her body pressed flush against his side . Her full, D cup breasts squished warmly against his shoulder, the thin fabric of her grease-stained tank top doing nothing to hide the soft give of them. He could feel every curve molding to him, her nipples hardening just enough from the friction to poke teasingly through the material. Heat flooded his furry cheeks and so did something else that was lower, much lower… his traitorous body reacted. ‘No, no, no,’ his brain screamed, but his cock had other ideas, twitching to life in his lab pants, thickening against the confines of his boxers.

"P-personal space Hatsume!" he growled lustfully through gritted teeth, trying to shrug her off without spilling his notes. But Mei was relentless, her hands roaming lower now, tracing the ridges of his abs through his shirt and lab coat, fingers dipping dangerously close to his waistband. Her scent that overwhelming mix of soap, sweat, machine oil, and something sweetly feminine assaulted his heightened senses through the mask's filters with her being so close, making his head spin and his dick throb harder.

Mei paused, her reticle eyes flicking downward as she felt the shift against her thigh. A mischievous grin split her face, wide and wicked. "Oho? What's this? Dr. Fluffy's got his own chemical experiment going on down there!" She didn't pull away instead, she invaded further, her hip grinding playfully against his growing bulge. One hand abandoned his chest to boldly cup the outline of his erection through the fabric, squeezing with inventor-like curiosity As her other hand pulled off his gas mask, throwing it behind her carelessly, making his mind nearly go blank from all the sensations and overload. "Damn, it's huge! And getting harder by the second. You do like how I smell, don't you? Admit it, my scent's got your tail wagging!"

Dr. K's ears flattened against his skull, he drooled as his cock strained fully erect now, a solid seven inches of throbbing heat tenting his pants obscenely. Precum beaded at the tip, soaking through in a dark spot. "H-Hatsume, you!-” His words choked off into a strangled yelp as she gave it a firm, experimental stroke, her thumb circling the head through the cloth making him shudder in pleasure. His claws scraped the chair as he growled.

"Aww, don't be shy! Science demands data right!" Mei giggled, her free hand yanking at his belt buckle with the same efficiency she used on her gadgets. The leather snapped free, zipper rasping down in a heartbeat. Before he could even think to lunge away, she hooked her fingers into his waistband and yanked lab pants and boxers pooling at his ankles in one swift, unceremonious tug. His cock sprang free, bobbing heavily in the lab air: thick, veined, flushed deep pink at the tip, with a slight upward curve and a glistening pearl of precum dripping from the slit. His heavy balls hung full and fuzzy below, white fluffy fur framing the whole package like some erotic beast-man fantasy, he didn't smell half bad either, she gently fondled his furry orbs. And without his gas mask Dr.Ks expressions were adorable. “You're blushing. And I just wonder how pent up you are.”

Dr. K slammed his paws over his lap attempting to cover himself, his face burning hotter than a soldering iron without his gas mask. "H-hatsume?! this is a lab… not a strip club!" But his voice cracked, hips bucking involuntarily as the cool air teased his exposed length, making it twitch and leak more as his hyper sensitive body reacted to every little touch.

Mei leaned in even closer, her breasts heaving against him as she stared at his dick like it was her latest prototype. “Look at that girth, perfect for testing friction coefficients. Bet it'd feel amazing in a custom sleeve I could whip up… But i'll gladly test it first, you always need a controlled variable right!" Her fingers danced teasingly along his inner thigh, inching closer to his twitching shaft as he huffed, eyes rolling back. "C'mon, Dr. K, let me measure it properly. Pretty please? For science?"

“I- Mei…” He was done for. Utterly and scientifically screwed in more ways then he could count… and at this point he didn't want to fight her advances.
