Molded by Miruko(Deku/Uraraka Bunnygirl TfTg)

"NO NO NO! YOUR TEAMWORK'S SLOPPY AND YOU CAN'T KEEP PACE WITH ME! UGH THIS IS WHY I HATE HAVING TO LOOK AFTER UNTRAINED KITS!"

Deku was gasping for breath, Uraraka in even worse shape as the two heroes in training felt like they had just been wrung dry of all their energy after having to keep pace with one of the Hero Association's most physical fighters. Miruko was largely unimpressed with their performance, surprised that they got this tired after just five hours of physical training. Why did the association insist on sending these half finished hasbeens her way? She made it very clear she preferred to work alone. Hell Hawks never had to deal with the brats so why did she? She was in the top ten after all for popularity, though some of her popularity was... Well Mount Lady and Midnight might like their perverts, but it was nice to have being a hero as a backup in case she had to leave any awkward confrontations. She'd just work these two kiddies until they said uncle and she could go back to doing what she did best; kicking ass. Alone.

Deku could already tell that that was on the hero's mind, her trademark impatient heel stamp faster than the gossip columns said, some of the pavement actually cracking as she looked vaguely annoyed to even be there. This was bad. Neither he nor Uraraka could afford to fail this internship. Okay that wasn't true, they were pretty solid in their class rankings and had the leeway to fail, but that kind of thinking would never get you to number one! Plus he would feel terribly embarrassed to report to All Might about such a blatant failure on his part. He'd feel Mirio's eyes for the rest of the month. Uraraka for her part had hung in admirably, all of her training paying off, but she was at the end of her rope, so tired that her nausea issue had returned, breathless and dizzy leaving Deku the only one able to talk their way out of this. Thankfully he had a plan.

While it wasn't much, his extensive notes on every hero working included personality charts and descriptors, and Miruko despite her brash, confident charge towards anything in her way, was sweeter than she let on. She was especially susceptible to praise as long as it was about her abilities. Mentioning her body usually was followed up by either her hopping away or a supersonic kick to the solar plexus that'd leave you struggling for air for a solid minute, so that was to be avoided at all costs. Even though All Might was his number one, it was okay to bend the truth a little here surely. After all he did admire all the other heroes in their own way, he'd just have to channel that.

"You're right! That's why we wanted to learn from the very best! Isn't that right Ochako?"

Miruko's impatient stamping paused, her ears quivering like tv antennas in the wind as her annoyed look softened slightly. Ochako quickly nodded along, catching up on her breathing as she gasped out, "Y-Yeah! I always HFF wanted to HFF be just like HFF you..." She beamed her best innocent smile, understanding what Deku was doing and laying on the flattery thick.

"No other hero is as powerful or successful as you. You're so strong! And you always look-"

Deku flashed her a no go signal, Ochako quickly adjusting on the fly, "gallant when you stop crime! Your quirk is just too amazing for us to keep up, b-but we still want to do our best!"

A slight blush crept up Miruko's cheeks, the corners of her lips twitching up into a half smile.

"Most powerful eh? I'm glad some people appreciate my work. Yeah I am pretty awesome aren't I? Even more awesome than All Might?"

She directed that question at Deku, Ochako's eyes drilling a hole in the back of his head as he swallowed his pride as a lifelong fan of the hero.

"D-Definitely! That's why we chose you! So we could get closer to our idol!"

That wasn't true at all, but Deku was banking on the fact that Miruko probably didn't remember much of her internship process and how the third round ones were randomly decided. And the smug smirk on her face seemed to confirm all he needed.

"Well I mean I don't like to brag but I was almost on pace with All Might for a few years and I'm always the first one in the thick of it when anything crazy happens in my zone. Hmm, you two might be kits, but I might be able to help you both mature a bit quicker. Uh, you did want to be like me right? Cause I never meant to use..."

She mumbled something to herself, sounding almost like Deku when he got in a trance, her small tail bristling as a hand stroked the fur, her other grabbing both her ears in a manner that looked suggestive, though Deku had no idea what she could be talking about. Still, both him and Uraraka were finally seeing some hope of passing, so they gladly nodded.

"Of course we want to be like you senpai!"

"You're the greatest!"

"The most graceful!"

"And you have such um... greatness about you!"

Deku clearly wasn't good at improv, but it didn't matter, Miruko coming to a decision as she analyzed the two's body languages, seeing that telltale awkwardness of two people not admitting their feelings as they stood just a tad apart, and they seemed so eager to improve too. Well, if they wanted it...

"Alright you runts, get ready for bunny boot camp! This'll only take a few minutes, but you should both come out of it brand new!"

The last thing either student expected was for Miruko to yank at her bunny manifestations, her ears popping off, another pair popping out as the same happened with her tail, a large plug like attachment on the end of it throbbing as she moaned, the painful looking process sounding like it felt a whole lot better than it looked. It was in this stunned state that she slammed her bunny ears onto Deku, smiling as his "training" began.

At first all Deku felt was pain, intense, unthinkable pain as the bases of the bunny ears melded to his scalp before drilling in, turning like nails as they pierced his skull and stabbed into his brain with a series of loud, revolting crunches.

"Deku?! What did you do to him?!"

Ochako was obviously concerned seeing her close friend suddenly collapse to the ground in pain, screaming as his hair twisted around them, looking fuller the more it bounced around as he tugged at them. Miruko didn't seem all that worried, all things considered.

"Oh he's just being a wimp. It's only painful for the first twenty seconds but once they stab into your pleasure centers that's when the fun really-"

"OHHHH~!"

As if on cue, his screams went from pain to pleasure, drool pooling down his chin as a thick blush colored his cheeks, the tight spandex of his outfit showing off how much he was enjoying it as Ochako's protests paused at the sight of his dick. It was bigger than she imagined it would be, her focus lost as Miruko slipped behind her, her spare tail throbbing as she grabbed the exhausted hero, consoling her as she squirmed.

"Enjoying the show he's putting on? I figured you two had a thing going on. Thankfully you have less I need to change so this should be quick and painless. Though you better change quick if you want to have some fun with uh, whatever green haired kid's name was."

With that out of the way, Miruko slammed the tail plug straight between Ochako's cheeks, her eyes widening with surprise and lust as the inside nib probed her deep, her cries resolving to forlorn moans as her body trembled with the advent of change.

Deku had lost track of himself at the first press into his skull, his body erupting in ecstasy beyond anything he had ever experienced, his thrashing about only turning him on more as it felt like every pore was contracting and buzzing with energy. Sweat pooled down every crevice, making his thrashing more lubricated in the suit, heat building as hairs fizzled and plucked themselves off. A luxurious softness encompassed his whole body quickly, the top few well worn layers shed leaving the new skin smoother, softer and sensitive to the most minute shifts. To put it another way, every touch felt suggestive, his latex suit's tight clutch on his body like a group of lovers teasing him as his moans came out higher than he expected.

It felt like he was melting, something in his throat liquifying, his moans dribbling out as a feminine coo while his body felt like it was shrinking. It was like vertigo, only he wasn't staring off the top of a roof, but thrashing on the ground, watching as buildings and trees seemed to recede subtly, his eyes burning as tears poured down their growing size, lashes tangling together as they grew thicker and longer and paired beautifully with his now plucked eyebrows. He tried to release energy to cool down, grunting as his shoulders blasted clean off, his powers running amuck as half his back became exposed, followed by his thighs and ass as the muscles spasmed uncontrollably. Deku felt his body, realizing stupidly that his gloves were still on, yet the press of his fingers felt like they were wrapped in jello, a layer of mushy something surrounding the more solid, slender innards that should have been pressing against his body. He was so confused by this development that he clasped his fingers together, trying to figure out just what this feeling was, gasping as an inadvertently tight grip sent the flab flowing upwards, squirming past his arms and jabbing into the gaps of muscle sitting right behind his nipples.

Uraraka was faring no better, tumbling through the air as her quirk kept her suspended, her thrashing looking like an impossible acrobatic feat as the butt plug swelled inside her asshole. It throbbed, pleasuring her in ways she hadn't breached past consideration, her face red with shame as her panties grew damper by the second. Worse, the tail had torn through her suit, leaving her thighs half exposed and panties tattered at the top. Every throb brought her tumbling faster, her ass cheeks swelling against it, feeling like her engorged clit as something sinewy and rough groped the sensitive fat in her ass. With a feel she realized what it was, her probing fingers denting less and less in the plush perk of her rear, finding a dense layer of muscle forming swaddled in plush fat. Of course she had been working out a lot more recently, but this was a whole other plateau of strength, intoxicatingly powerful as her own muscle smacked and jostled her ass to her increasing delight.

Despite the consistent pleasure coursing through her, nothing could have prepared her for the upwards slam of the tail, her insides thoroughly stirred as she squealed, the muscle parting as the tail melted into the base of her spine, sensory organs blaring to life as the sudden increase in pleasure made her slam her crotch against the air, a hand desperately chasing it through her aerial twirls so she'd have something to grind against as her thighs grew slick with cum. It was like a rusty lever being yanked into an on position, each notch of spine it brushed past raising the ecstasy until the world was a dizzy blur, Ochako not caring once her fingers found her slit, her full hand thrusting against her crotch as the bunny tail finished its winched climb into her spine. It was overwhelming, ecstatic, and multifaceted, her orgasms giving her abs years of training as they flexed and spasmed, looking smooth and plush over the steely strength climbing steadily towards her breasts.

Speaking of breasts Deku was getting a firsthand experience with them, screaming as his nipples were tweaked by latex, swelling against it as the flattening jelly feel of feminization traveled up his arms. None of his muscle was sacrificed, just compressed harder than diamond, his sleek arms slender now and cupped gently by his separated sleeves, the one size fits all design from Mei keeping them form fitting as he rolled over, rubbing his groin against the ground needily, his rising breasts making his usual inhibitions sputter out as the need was too strong, his horniness ever growing. The ears were messing with his brain, egging him on as the breast fixation he usually worked hard to stifle was brought to the forefront, his eyes glued on his own rising chest, the pleasure instantaneous as a hand awkwardly grabbed one of the rising b cups.

"OHHHHHHHH~!"

The shock of pleasure sent his cheeks crumbling, softened down to smooth contours that made his freckled blush all the cuter, his pursed lips swelling as his other hand joined in, probing a nipple before pinching it, the maneuver sending him rolling as he felt his cock tighten, one unsatisfying orgasm spilling down his thighs as he mewled in delight.

"OHH YESSSS! AHH AHH AHHHHH~!"

It was all so wrong and alien, yet it felt too good, Deku's chin snapping as he bellowed with lustful abandon, hyperventilating between squeals as his tummy tightened, pressure rising as his sides began to creak. Somehow he hadn't put two and two together yet, on what he was turning into, Miruko's bunny quirk infecting him as it mixed intimately with his One For All, her quirk and her genome boiling through him as his sides collapsed into sexiness, all that muscle and fat erupting into two massive breasts that swallowed his hands in an instant. That was enough to shock him out of his pleasured stupor, even as he came, moaning as each tweak drove his masculine stores out in a flurry from his cock.

True to her words, Ochako's changes were happening much faster, the near immediate acceptance and her own fevered fingering aiding the strength filling her, threading into her thighs, defining her abs more as her figure cinched in just a tad extra, her breasts getting a slight boost as her thoughts gravitated towards Deku. Just like the muscle bubbling up under her skin, her true feelings and crush was coming out into the light, no longer able to be denied or deferred, her fingers not feeling half as good as she imagined his cock would. Oh god she was so horny, and so strong. She felt like she could crush a person between her thighs, yet she knew Deku would be able to handle her. Mmm god she could just imagine him handling her already...

Her reluctance and worries pooled into two separate spots on her skull, her only mental roadblocks being crowded out with thoughts of sex and the confidence to not even consider failure as an option. Pressure was building, like a migraine that gave only pleasure as pops rolled through the top of her skull, her ears flexing as her brain's thought of ears felt like there should be more than just one set, her temples throbbing as she felt she had to- h-had to-

CHSLRRP

"KYAAAAAA~!"

The bunny ears erupted out, brown and sensitive, a perfect match to her hair as they stiffened, the cool air fondling them as if they were two large, erect nipples. The world was a dizzying blur, her floating quirk leaving her spinning as she finished fingering herself, the head rush that came with slowing down letting her mind further free itself from worries as it all boiled down to a simple question. Did she want it? Yes. Then what was she worried about. Besides she didn't even worry that Deku wouldn't find the new her sexy. Now where-

"GAAAHHH~ N-NOOO N-HAAAWT MY-"

Ooh, it sounded like Deku was having fun already. Surely there was room for one more.

Deku could no longer look down. Not effectively at least, his bosom blocking all attempts to see what was happening to his lower half. He had to go by feel and what he felt was hard to handle, much less resist. It was like something was nagging at his balls, plucking at them as they squeezed tighter and tighter, his cock never this hard or this raw as it flicked into the well defined push of his svelte waist. Feeling it his waist was still firm, but plush, that strength hiding behind unbelievably smooth skin, his fingers dancing along the the curves of his body. A manic smile played at the edges of his lips, a small voice insisting how good this was, how strong he was becoming. So what if he lost his masculinity, he'd definitely be able to go 100% after this was, w-was-

"NOOO~! I D-DON'T WANNA BE A- NNGH s-sexy OHH~ thick..."

SCHLICK

"OHHH GAAAWWWWD~!"

The pulling turned into a yank, Deku's thighs clenching together as he felt something worm its way in under his cock, the thick sludge pooling down feeling thinner as it rushed out, his will teetering as the worm found a new nest after burrowing deep into his left side, estrogen pouring into his thighs. It flowed like hot magma, thickening wherever it pooled and cooled, his ass waving in the air as his left cheek wobbled out to a round, curvy bun. His thigh was similarly affected, bloating out, caressing his cock as he begged for it to stop, moaning harder as his remaining ball tensed and sucked inside with a moist sounding SPLLSH.

"GAAAAHHH~ N-NOOO N-HAAAWT MY-"

"Mmm~ Deku?"

It was a brief distraction, Deku's eyes lidded as he looked over, gasping as he felt his jewel stab deeper inside.

"O-Ochako heeelp m-EEEE~!"

He was shocked at her appearance, the aroused bunnygirl stripped naked as she sauntered over to him, eyes brimming with lust. His tense muscles relaxed as fat evened out his curves, one final shocked squeak erupting in time with his bushy bunny tail.

Ochako felt bad for him, seeing him clearly struggling with that thing between his legs when it should be between hers, though the more she looked at his soft form, the more her mind told her that this was right, that she liked him smooth and sleek and... girly. Why was he even fighting it? They both said they wanted to be like Miruko, and god did it feel amazing to be like her. Even his ears showed he wasn't accepting it yet, a bit of green only coloring the very bottoms, his trembling features cute, but not cute enough. Seeing him so helpless just made her confidence push her to him, whispering an affirming, "Don't worry Deku I'll help you out" that came out more threatening than she had envisioned. Not that it mattered, the horny hero putty in her hands as she floated down atop his cock, flicking it free from his spandex before squeezing it inside her muscled pussy.

"AHHH GAAAWWWD OCHAKO STAAAAWWWP~!"

She giggled, drooling herself as their tits slammed together, green creeping up the tips of his white furred ears.

"Shhh, stop fighting it. Didn't you want to be number one? Together with your number one?"

She rode him hard, slamming her hips down, each thrust pushing his cock in a bit as she felt the balless shaft swell and cough out vaginal fluids. His gaze was getting duller, glassy eyed as it only reflected her o face back to her, Deku's hair spilling down further into softer tangles. It was like they were made for each other, their curves overlapping, their bodies coiling tighter as the feel of their muscles bouncing when the fucking grew especially hard made it impossible to resist, Deku's cock giving a final retreat as their thighs wrapped together, forcing it down into a slit. She had said the words that gave that final mental push needed, his thoughts of All Might and being number one still there, but balanced with her partner, her lover, her other half, Izumiko moaning as her cock popped into an engorged clit.

Miruko let the two use up all their spare energy as they went at it, nodding approvingly at their vastly improved teamwork as the two lovers were quick to respond to even the slightest of cues from the other. Apparently the dna absorption of One For All was a bit too powerful, Miruko surprised when Ochako tore off Izumiko's clothes to reveal green fur in the shape of a cute outfit. Either way from how long they were going at it she knew their stamina must have improved greatly so mission accomplished. She just hoped she wouldn't have to pull them apart if she wanted to continue their training, though it seemed likely.

Actually wait, how the hell would she explain this when they returned to school? Eh who cared. They were clearly better and with their looks they'd have no issue gaining a creep army to fawn over them. Everything she did was right as far as she was concerned and it'd be a problem for future Miruko. Now could she use active crimes as an excuse to dip out of an association hearing...

-----------------

Inside Deku the past fragments of One For All were arguing over what to do.

"Can't we purge this stupid bunny crap from our system?"

"Perhaps it could be a trap since All For One is on the prowl for our quirk."

"Well I think we should- NNGH o-ohh~..."

The internal debate from past users paused when they noticed Nana Shimura, the one female inheritor's hero outfit glow green before shifting into a tight black bunny girl costume, her size diminishing as all lost muscle migrated towards her breasts.

"How can this- M-My danger detector is g-OHH~ing o-awwf~"

"What's happening to UNGH ahhh no noohhh yesss~!"

Cocks popped into pussies as the past successors succumbed to the bunny girl quirk, mixing with their own as Deku now contained the horniness and experience of eight past users. It didn't matter how muscled or bulky they were, all were compressed into thin little girls, each clad in black latex as the ones who changed first hopped on the remnants still defying the merging. A new plan was soon agreed upon to take care of All For One, well as soon as nine generations of pent up lust could be exhausted as Izumiko realized she might as well be live bait even if her girlfriend didn't like her phrasing it like that. But there wasn't any worry. The only question was how long would it take All For One to start turning into a horny bunnygirl like them before he lost all ambition.

Of course there was one teeny little problem to consider on if with his quirk he would create a bunnygirl virus that'd turn all of humanity into muscled nymphos, but they kept that possibility quiet. After all, didn't that just sound like an amazing time?
