#1 In Your Heart (Bakugou To Nana Shimura TG)

I'll just warn some minor spoilers for MHA vaguely since this takes place a bit after the epilogue when they're all in their mid 20's

"GAHHH AHHH GOD MY AAAAAAARM!"

Bakugou looked on confused, Deku aghast at the mangled sight of the villain who had just seemingly self-destructed in front of them.

"You okay Midoriya?"

"I don't think I'm the one in trouble here."

"You're the one who got hit by some weird beam before uh... this."

As far as they were aware, some weirdo had jumped out, proudly called himself "The Taker" and blasted Deku who was doing a ride along inside their mech suit. It'd cost a shit ton out of Bakugou's pocket so he was happy at least that Deku seemed fine, but it had been an utterly bizarre moment. No sooner had he rattled off about "Being the second coming of the demon lord" that he tried to seemingly show off only for his whole arm and shoulder to suddenly break apart to all three's shock.

"You know he kind of reminds me of you back when- Blegh!"

Bakugou quickly regretted leaning over, some kind of artery opening during the failed villain's squirming as a jet of blood shot right into his open mouth, the shock making him swallow while Deku rushed to give first aid. He didn't want to make too big a deal out of his own stupidity, especially since this was supposed to be Deku's return to the front lines, and it helped that it wasn't bitter or anything just a bit coppery with a weird tang of sweetness to it as a small shiver ran down his body.

"Nooo l-losing power. Why am... I..."

Neither were shocked to see him gradually losing consciousness, Deku mumbling about anemia and medical stuff while Bakugou pretended to know what he was saying, feeling weirdly fidgety the longer he stared at Deku as he rambled on about first aid. Maybe it was just gratifying to be side to side with his bestie, have him so close, the dork still just as jacked as before…

He shook his head, the intrusive thought making him blush, his cheeks feeling hot. It was subtle but the heat of his blush was beginning to de-wrinkle the anger folds around his eyes, the loud thudding of his heart drowning out more of Deku's speech as he felt enamored watching Deku care so much for a villain, looking so dreamy...

Okay something was weird here, Bakugou breathing deeply, catching a whiff of Deku's sweat as the shivers worsened, a slight twitch between his thighs making him go wide-eyed as he shifted awkwardly. Shit why was he feeling so bothered by Deku? It was almost like he w-was- No that'd be fucking stupid!

The collapsed villain was in no state to explain any of this, a series of bad miscalculations leading to a one in a million oddity. The Taker's ability was to steal people's quirks, and such a busted ability had made him overconfident. He didn't just want to debut, he wanted to make a statement and what better way than to steal from the honorary top hero? While Midoriya's One For All had all but burnt away, the embers still had ashes, the most resilient and stubborn of the past successors laying dormant inside Deku's genes and rudely ripped out and shaken awake by the steal.

Unluckily for him, the AFO wannabe had wanted to show off his super strength, his reedy body unable to handle even a percentage of the stored energy and as the pain ripped through his panicking nervous system, two things had happened. One: An intense inner scream to get it out get it out and Two: DNA flying out and entering Bakugou's mouth, the stolen quirk still following the rules as it faded from his body, the burnt ashes sparking inside his body as nitroglycerin rekindled the ashes into a flame. And after years of being stuck not even in the passenger seat but the trunk, said flame was ready to turn into a mighty inferno as Bakugou's body became damp and sweaty the longer he stared at Deku Deku Deeeekuuuu~

"On-site first-aid has been done so he should be fine once the medical- Eh Bakugou? I-I mean Murder God Dynamight are you okay?"

Shit he was making Deku worry now, all sorts of weird spasms rolling through his muscles as his skin felt tight, each beat of his heart making his body tremble as chilly tingles ran over the bevy of burn microscars all across his body. He felt weak, his body clammy as Deku looked him up and down, Bakugou feeling embarrassed as he clenched his legs shut to avoid any unwanted surprises from peeking out his latex.

"J-Juhhst a bit light h-headed I- NGGGGAAAAH~!"

It felt like something had just stabbed into his guts, the visceral grunt masking the moan that followed as his pants felt tight. A thin gap had just pried between his hips, the bones jutting awkwardly as he stumbled to the ground. He tried to keep himself upright, but it was like every muscle had fallen half asleep on his body, the world spinning as he thudded to the ground.

Now Deku was over him, the position making his mind race, feeling like he'd just been pushed down roughly by such a sweet, heroic- Shit shit shit his cock was really getting hard to keep hidden between his thighs, all these flashes of want sparking over his skin as flecks of another quirk slowly spread throughout his biology, crumbs of scar tissue jerking upwards before crumbling off, his roughened exterior starting to smooth over in more ways than one, but his interior was where the real changes were starting.

"Don't worry I already called medical they're only a minute-"

"No! Just g-get me back home. Please."

Even if Bakugou had chilled out relative to his high school days, being asked like that was still so out of character it stunned Deku for a moment. God he looked cute with his mouth open like tha- Bakugou's brow flexed as if he could squash the horny thighs like his legs were trying down below, Deku letting him lean on him as he waited for medical to arrive before pulling him into his arms.

"Wh-What're you-"

"Just hold tight, we'll be at your place in a few minutes."

It was taking a lot not to swoon as he was lifted up, Bakugou half-worried his sweat would explode right then and there as a feeling like butterflies spread not in his stomach, but his balls. His gonads were brimming with estrogen, his endocrine system going haywire as muscle churned inside, feeling like cream thickening to butter.

It's been ages since someone tried to princess carry me. Ohh~ what a gentleman, wouldn't you agree?

The voice rang loud and clear. rumbling over his body as he gasped, his skin feeling more like sausage wrapping as muscle broke down and reformed internally at impossible rates. Great now he was hearing voices in his head on top of feeling like he was gonna burst any-

Hey I'm not just some silly voice. I'm really here! And here to stay. I don't know why One For All's going out of control like this, buuuut I'd like to try to make this less of a takeover and more a… sexy compromise.

"What the hell are you talking about?!"

Deku was glad he was mid arc in a jump, fumbling a bit but the landing controls fixed any awkwardness in form.

"I didn't say anything. Are you sure you don't want me to take you to a hospital?"

Both voices shouted yes though he doubted it was convincing, his heart swooning a little at how nice Deku was being, so eager to listen and do what people want-

S-Stop messing with my head!

It felt weird to think it, the mature giggles in response ticking him off more with that air of “I know something you don't” condescension.

Oh it's not that I know something you don't. I just can feel what you're really feeling. Your precious 'Deku' is taking up a lot of real estate in here. And I can see why, saving you like a knight in shining armor. Mmm~ no wonder you're all fidgety.

Bakugou groaned, thankful Deku wasn't looking down as his cock slid up, stretching his suit noticeably but then again, so was the rest of his body.

The churning was getting faster, the roots of his hair darkening as they slid out his throbbing forehead. His head seemed to be the one thing that wasn't trying to grow, his frustration creases smoothening over, a feverish gleam building in his eyes as despite the feeling of being overstuffed, he felt giddy to be in Deku's arms, to have him carrying him like a pincehhss~

Stahhhp! I-I'm not into Deku l-like nngh...

It felt like serotonin and adrenaline were rummaging through his brain, his breathing growing more erratic as the lines of his musculature were deepening, more meat hugged tightly as muscle poked under his nipples, more of a new quirk pooling under as Float tugged on his inert flesh, nerves swirling up and up as they perked tightly over widening areolas. Beyond how good it felt, the worst part was how easily Bakugou kept imagining Deku's strong hands pulling them, teasing them. Making him his-

"NNGH MMM Hahh haah..."

It had proven too much, the fantasy, the feeling of his skin softening to tender creaminess while muscles buzzed and grew underneath, and his nipples being tweaked from inside had driven him over the edge as his latex pants grew slick with cum, his hips shaking themselves even wider. Thankfully the sound of wind whipping past hid the noise of his hips spreading an inch apart, though it'd only be a matter of time till Deku noticed. He was so attentive like that.

Oh really? ‘Cause the more I look through your thoughts, the more I feel something stronger than just friendship here.

A slideshow of moments ran through his consciousness, each one of Deku saving him, helping him, tender moments that with every flash made his nipples throb as slivers of fat began to arc them into beestings. And despite his groans and struggles to deny it, each one was getting him hard again, thinking of Deku working him up as the voice in his head giggled knowingly.

I mean I don't see any girlfriend, and half your salary went towards getting his suit, all so you could both be together again. So romantic.

It felt like his heart was gonna burst, each beat struggling through denser muscle as his skin stretched, hairs popping out his fully smoothened skin shook off the last of its burn scars, a different kind of texture outlining it as his abs gained another set, the throbs gradually chiseling out lines from his toned physique into something even more bluntly muscular, the buzz making his skin feel like it was vibrating from his cock to his swollen nips.

"N-No! That's nahhht NNNGH!"

"Don't worry, we're almost there."

Bakugou groaned at hearing Deku's voice, another wad splashing through his skintight pants as his elastic top gradually slid up his waist, everything looking a size too small as his hero boots scrunched against his toes. And no matter how hard he wanted to deny it, his thoughts were still clouded with Deku, feeling like he could just melt if only Deku was into him too...

But that's where I come in! Isn't this convenient? Here you were one half of a hopeless romance, just settling for spending more time with him, but now we can shoot for something deeper...

Another surge of adrenaline, Bakugou struggling not to squeal as his spine slightly bent, the whole thing being squeezed by a cage of muscle, the sections easing it upwards as the vertebrae subtly lengthened.

No this i-isn't...

He could feel it, something shifting below his navel, a groan rasping out as Deku's grip shifted to be more caring. It felt good, more flashes of Deku getting him heated as his panted breaths climbed, the swan like muscle of his neck thickening inwards as it squeezed his Adam's Apple, his lips squirming from his usual frown to a more neutral squiggle. It was like a tightness in his cheeks, urging him to smirk, his lips trembling as their cracked edges smoothened to a lush pink.

"We're here."

Bakugou was jostled out of his inner boiling horniness by the landing Deku easing him back to his feet only for Bakugou to slouch forwards as his scrunched feet fumbled awkwardly in their too tiny boots, even the muscles in his cock getting thicker as it felt like each throb was making it tease itself.

"Here I'll help you ins- Um..."

Deku decided not to say anything, sure it had to be due to the wind that left Bakugou in such an odd state. It was almost like seeing an adult in teen clothes, his belly button exposed and gleaming, calves slipping out of pants so tight they looked more like leggings. Also had he always been so jacked? And tall... No that didn't make any sense and besides if anyone was going to be feeling weird it'd be him and not Bakugou. But maybe he should stay the night since he seemed really-

"H-ehhhhhlp me inside. N-Need you NNGH!"

Saying he needed Deku sent the changes into overdrive, his heart thumping like his quirk was trying to blow it up,  more muscle packing on as his balls burrowed against his groin. His sweat soaked hair was darkening further at the roots, spilling down his cheeks and tickling the nape of his neck, a sensation that quickly shifted to images of Deku nuzzling her in bed.

"Haaaaah~ ahh ahhh~!"

He couldn't help the groans, relying more and more on Deku's weight as leaning grew awkward, his spine adding another inch as the internal muscle continued to build. The soles of his boots were reaching their limits, glue peeling off, strings plinking in two with each step as his toes squirmed and peeked out the flopping remnants of his costume. Fuck it was so tight, and he felt sooo much stronger...

He's so gentle and attentive. Mmm~ I knew he'd be a good match. I love a dashing hero and so do you.

He didn't even deny it, the moment of Deku rescuing him from that weird slime thing replaying with every needy throb of his cock, his tongue moistening lips plumping as the edges curled slightly up.

That's it. You want your hero to notice you, don't you? And you know what he likes. Can't blame him, I love a nice meaty pair of pecs too, but these... Well they're barely even beestings. Mosquito bites?

His nipples throbbed, tears leaking out the corners of his eyes as the sockets warped, his lashes growing as they started to slant. She was right, Deku always at his most flustered when Ochaco or Mei had their tits half shoved in his face, Momo's hero outfit also an eyesore. And all he had were these sensitive, but utterly pitiful lumps barely pressing against his tank top.

All you gotta do is ask. Mmm~ it's been so long since I've been able to vent these feelings. Being the only girl stuck amongst so many adorable boys and no way to let loose. And he's right next to you. Doesn't he look so cute? Don't you wanna surprise him? Make him yours?

There was a bit more of a pop as his chin rounded, a dark beauty mark burning onto his skin as his nipples swelled, the muscle bulging into a firm base that was begging for some heft. All the while his body continued to grow, boots popping as his feet burst through the lining, muscle massaging his arches wider as they gained a dainty appeal all while still being packed with muscle. They were almost at his bedroom, Deku talking like a worried mom to their child about soup and water and plenty of rest, his nerdy caring yapping likely to stop as he teetered near his bed. Deku didn't have any reason to stay. Deku was going to leave. He needed him so badly s-soooo~!

"Y-Yessss~ I waaaant it I- AH H-AHHHHHN~! DEHHHHHKUUUU~!"

Bakugou stumbled forwards, collapsing onto his bed face first as he screamed, Deku stunned as his friend suddenly moaned his name, his voice cracking upwards though that wasn't the only thing-

CRACK CRUNCH POP

Nakugou gasped as the breath was squeezed out, hands clenched around his navel as ribcage shifted, muscle condensing as his whole core squeezed itself desperately as if desperate to be huggable. Despite the shift and squeeze, Bakugou's frame was somehow growing, lengths of spine curving with a noise like a chain of firecrackers going off, his latex hero shirt more like a crop top as it revealed ab after ab of bulging muscle, steely yet pliable as his body wriggled, tears forming in his bottoms as his hips unclenched another inch wider.

Hmmgh~ ahh f-feels good to be gehhtting so physical ahhfter so long. Nngh ready to be Deku's type?

"YES YES YESSSSSSSS~!"

He pulled up the struggling crop top, exposing his pink nips to the cool air as they built into more obvious cones. The churning inside hastened, muscle squirming together, each breath in sinking his muscled core curvier as weaker stuff was squeezed and siphoned upwards. All of it exploded under his nipples, Nakugou squealing as ropes of masculinity lubed up his bulging thighs, Deku's eyes bulging wider as his friend's exposed chest became jigglier by the second.

Each surge in cup size pulled the sides of his smile higher, luscious lips moaning, a strong, sharp nose topping elegant eyes as Nankugou's hair burst out in  waves of darkening black, the pleasure unstoppable as the two voices both swooned at the sight of a clear tent in Deku's super suit.

"Oooh~ liiiike what you s-HEEE~?!"

Fatty pops burst and jiggled, Nankugou bucking as the extreme convulsions worked his core into a steely array of strength, his stomach rising as his spine crunched upwards to better show off the growing lumps of fat. Their tits seemed to be the only refuge for anything soft, half a foot of bulk adding to his frame, his shoulders actually spreading wider even as they sloped downwards, squirming needily as their tits began to bounce nicely with every orgasmic pop.

Deku hastily covered his rather obvious stiffy, his mind utterly stumped at how to react to any of this. Bakugou was moaning his name, growing tits and turning more familiar by the second as their legs kicked, dangling off the bed as each snap of her back gave her more to palm and squeeze as Deku mumbled out an utterly baffled, "N-Nana, is that you?"

"Oh? Ooh that sounds r-HII IIIIIGHT~ AHHH C-CAHHHN'T REALLY TAHHHHLK R-HIIIIIIIIIGH~!"

They were perfect to cup with their hands now, fingers stretching as muscle wormed its way into their palms, tris and bis tripling in size as they massaged their tits in a showy way, both eager to keep the attention of their scaroused audience.

Bliss was an understatement, their legs threatening to break the bed with the power of their pleasured bucks, their tits growing as swollen as any muscle on their body, plumpening into two jiggly mounds of their combined lust. Their features squeezed tight as they gave one shrill groan, hugging themself as they tensed their core, straining every last bit of fat to burst upwards as the near topless girl collapsed, massive e cups still firm despite their girth from how toned the rest of her body was, Nankuga giving Deku a cheery grin.

"Aww no need to hide it Deku, we're both ahhh~ eager to see it."

Nankuga was getting quite the show, turned on by her lagging bottom half while she played with her tits, Bakugou's merging memories giving her plenty of material to get excited by as multiple group shower days with all sorts of hunky boys mixed into her usual perversions. Having a pure flustered hunk squirming made it all the better, the edges for where the two inside began and ended blurring more and more.

"Nngh it's a shame you ahhhren't into boooys cause this th-heeng feels so sooo goood~!"

Normally she wouldn't be quite this forward sexually but as Nankuga's brain throbbed it was gaining that brash forwardness that defined Bakugou. Similarly, their legs were twitching, cum dribbling out the various tears as her hips crunched out another inch, then a second, Nankua groaning as their cock popped free from the torn latex, their former hero suit shredded apart which was a testament to their new girth given how much stress testing Mei had worked in.

Deku meanwhile had that adorable stunned look like a deer in headlights, his gaze clearly trying to avoid the throbbing cock stuck between two concrete slabs of thighs angled together. Yeah this wasn't gonna fly, but she was sure gonna make it float.

Hey Bakugou are ya ready to listen to all those annoying peeps and fuck yourself?

Nngh y-yeah screw it. I-If he asks I was coerced and this wasn't what I wanted but... DEEEEKUUU~!

Their two voices became one as Nanua used her ability remotely, dragging a spare black all size bodysuit from Bakugou's closet, one of those basic underlayers made for winter weather and also the only thing that'd fit as it fluttered towards her, Nanua giving her cock a fond fondle as it throbbed out cum.

"I'll juhhhst be ahhhnother MMPH m-ohhhment Dekuuu OOH OH YESSSSS~!"

There wasn't much thought needed, Nana spreading her quirk into her balls and cock, giving it a simple command to float up and in, forgetting about OFA's condensing power as she was suddenly fucked.

Anything masculine was quickly drilling into their spread open hips, their balls burrowing into dense, tight muscle, their cock erupting as every drop of testosterone was desperately ejected, squeezed out as their entire sack sank and split apart from a quirk on overdrive.

"HYAAAAAAAA~!"

Much like the fat that had exploded into breasts, her sunken testes sparked and burst as they channeled into ovaries, an estrogen bomb rippling through their lower half as fat squeezed past muscle to internally spank their shifting ass. Cum sputtered out as the last of their unwanted seed was expelled, clear, slippery squirts following as their cock squashed into their innards, shifting and pushing into the hollow gap that had punched apart their pelvis repeatedly, Nana's eyes rolling upwards as she felt her first good fuck in ages, Bakugou's cherry popping as the two in one both squealed and thrashed to the overwhelming fucking.

The thick muscle made it thrust like a jackhammer into their forming snatch, pounding and pounding as their ass bloated with each shuddering smack against their bed, the legs of it giving out halfway as thighs bloated to thick, melon crushing girth. It was all muscle, soft and bloated, but steely if you pressed it and god was their half sunken cock pressing as hard as possible. In and in they urged it, squeezing their thighs, the two united with one desire for a hero to ravish them as the muscle shuddered throughout their entire shaft. Each inch made her smile widen into a beaming grin, a manic sign of pure joy as her soft cheeks stretched. Eventually there was barely any left, Nana squeezing her core, a shuddering, blistering pop rocketing the rest inside as it spread open into a glistening slit as she came and came till her voice was hoarse from screaming Deku's name, her pearly whites twinkling on a joyous face as if made to give the biggest, brightest smile possible, no hint of her former grumpiness left.

 "Hff hff ohhh~ fuck that was intense. But I'm still so needy. Won't some brave hero save me?"

Her wide smirk didn't falter as she floated herself up, not done getting in the mood as she slipped into the black bodysuit, but it wasn't complete, the yellow boots half-stretched and soleless giving her an idea as she gestured towards the bathroom. Yellow plastic gloves completed the look as she slowly pulled them on, making sure to show off every new curve to a Deku whose hands were hung lifelessly to his sides, clearly unable to think at this point though it let her see just how hung her soon to be savior was as she floated down towards him, ready to have some fun.

Feeling her pull him down woke him from his stupor, Deku blushing as he was nearly muffled by her breasts as he tried to make any rational sense of this.

"W-Wait Nana how did you do this? What happened to Bakug-OHHH~ Ah w-wait a-"

Given Bakugou had helped so much with funding it, that meant he knew just which buttons to press to free Deku from his bottoms, shrugging at the questions.

"I don't know, but neither of us are complaining. Don't worry it's still me in here, it's just more of me, now hero won't you save-"

"B-B-But I don't understand how you could- Unless there were elements of my quirk left that were taken and..."

She did think it was adorable when he got all analytical about things, and she'd admired his heroic spirit ever since he had even told her off for wanting to save anyone he could. The two of her both felt saved by him but now they wanted something a bit more rough and holy shit he was still stammering out hypotheticals even with her all but ready to fuck-

"Okay listen hero! I worked hard to get you that stupid suit so you could go back to the front lines and it wasn't cheap! You owe me and I know you don't have anything else going on so you better show some fucking gratitude and some fucking!"

It at least eased Deku's worries to see Bakugou's personality leap back out. It was also distressing how arousing it was to have an over six foot tall woman like Nana yelling how much she wanted him and his love life had been pretty dry since his teaching track separated him from the rest of his class... 

"Erm, I can see you've been calling for help? I think I'll have to use all my might to... save you?"

Nana grinned even wider, reaching up to clap as her muscles tore through the bodysuit, even the ultra stretch not quite enough for her muscle arms.

"Ohhh~ my hero! Now please, rescue my maiden h-EAAAAR ARRRRT~!"

The bed was just a start. By the time the two were done, even the floors might be broken as the two gave their all in love.
