“Now shonen when we first met, you told me your Quirk was useless! How could you say that?! I saw your strength and speed! You yanked that boy with the explosive Quirk right out of the slime! I even saw you take a hit and not flinch! How could you call that a useless Quirk?” Toshinori asked his brand-new apprentice and future successor. Izuku still couldn’t believe this skeleton of a man was All Might. It might have only been three years since his injury, but that was more than enough to visibly sap the life from him.

“That wasn’t my Quirk.” Izuku answered flatly.

“…Come again?” Toshinori looked at him weirdly, “Was that just peak human physicality?”

“Yup. Or I guess you could call them my Quirk adaptations.” Izuku responded, his face deadpan.

“…Young Midoriya, what is your Quirk?” All Might deadpanned back.

“My Quirk… Well, let’s put it like this. If your role in life was determined by your Quirk… I’d be doomed to be a porn star.”

“…What?” The feeling of incredulity was so strong that he didn’t even have it in him to cough out blood in his shock.

“Yeah! My Quirk is Incubus. I’m basically a sex demon!” Izuku’s voice raised as his frustration started to pour out.

“…What?”

“It’s super distracting! I can’t go five feet next to a pretty girl without knowing her every dirty kink!” He started to build up a full head of steam with his rant. “I instantly know the best ways to seduce women and every single thing I can do to drive them wild!”

“…” Toshinori tried to open his mouth to respond, but he may as well have not even been there.

“Plus, I’m horny all damn day! Literally all damn day! I’m fucking horny now! I’ve been pitching a tent since I got a live view of Mt. Lady’s ass during her debut!” Izuku was not stopping, “I mean sure, I like sex as much as any teenager! But holy shit, it’s like I can’t focus on anything without it!”

“I…”

“I can’t even use my tentacles to rescue people!” He exploded, waving his arms with his face red from exertion, “They’re shaped like dicks! Why are they shaped like dicks?!” He showed them off, and they indeed looked like gigantic, prehensile penises straight out of a tentacle hentai. “I can’t rescue people with dick tentacles! That’s a lawsuit waiting to happen!” He panted, huffing from rage-xertion as he finally stopped ranting.

“I…I have zero words.” Toshinori half wanted to laugh, and half wanted to just smack his successor for complaining, “Are there any benefits?”

Izuku sighed, “Yeah, I suppose. Obviously I’m in peak health, and I wasn’t kidding when I said it was ‘Incubus.’ I get stronger from sex. Not by that much though. I don’t think it’s via stealing life force or anything like that, but it definitely happens.”

Toshinori chopped him on the head lightly and admonished him as the boy rubbed his head, “You, young man, are missing the forest for the trees. You’re looking at your Quirk from the wrong angle. Most Heroes would probably do some very questionable things to acquire the kind of physicality you get essentially for free just by doing something most guys your age are already obsessed with.”

Izuku sighed and slumped a bit, “I know. Honestly, I wouldn’t mind it so much if it wasn’t a constant thing. If I go more than a day or two without doing it, I can’t even look at an attractive girl without it acting up.” He grimaced, “Plus, it only activated when I hit puberty. Until then we thought I was Quirkless.” Toshinori grimaced at that knowledge, “They were all such cruel assholes that I absolutely refuse to do anything with anyone from my school. Which makes things really difficult when several of them are objectively attractive. Which means my pheromones also affect them and cause a feedback loop where I can smell how horny they are, which just gets me going even more. Going the entire school day with a stiffie is uncomfortable.”

“Okay, maybe I was underselling the issue a bit.” Toshinori admitted. He shook his head, “Any way to distract it?”

“Not really? I tried working out and stuff,” Izuku admitted, “But Quirks like these usually start going haywire if you try to ignore them. I tried going a week without doing it and my pheromones got so strong that even my mom started getting affected. I had to get the hell out before…” He slumped.

Toshinori cringed, “Okay, I’ll make sure to schedule in regular…ahem…breaks… while I’m writing your timetable.”

Izuku snorted, “Appreciated.” He said dryly.

“Well, I’ll go ahead and get started.” Toshinori told him, “Meet me at Dagobah Beach in three days at, say, six in the morning.”

“The dump?” Izuku asked, his brows furrowing.

“It won’t be a dump for long.” With those last words, Toshinori departed, wondering how One For All would affect Izuku’s original Quirk.

-]|[-

“I’m cleaning all of this?!” Izuku asked incredulously as he looked around, “Holy shit…” He muttered in English, getting a laugh out of his new mentor.

“That’s right! We’ve got several good miles of beach that have been turned into a travesty!” Toshinori grinned, “Too many people, no, too many Heroes have forgotten what heroism is all about. This polluted eyesore has stood for far too many years from the illegal dumping, and it’s clear the city won’t do anything about it. We’re not just going to train you. You’ll be performing this community service too!”

“Hmm…” Izuku hummed as he slowly spun in a circle, “Question. What about actual training? Like, fight training?”

“We’ll handle that once the beach is clear and I know you’re ready to inherit One For All.” Toshinori replied, sitting on a rusted and pillaged husk of a car. He was almost tempted to save this thing. It was a classic! How the heck did an American classic end up on a Japanese beach several centuries after it was made?

“Uhhh…” Izuku wondered if he should say anything but decided to go ahead. He didn’t think Toshinori was the type to change his mind if questioned, “No offense All Might, but isn’t that kind of dumb?”

Toshinori crossed his arms, “Fighting with and without it will be very different.” He told his successor, “Yeah, you can learn the basics before it, but several impossibilities become possible with One For All.”

“That actually wasn’t what I was getting at, but good to know.” Izuku replied, “If you give me One For All, then it stands to reason that you’ll lose it, right?”

“Figured that out, huh?” Toshinori grinned, glad to know there was a brain there too, “It will be gradual, but yes.”

“And how long do you think it’ll take me to clear this out and be ready?” Izuku asked.

“A year, max, unless you’re lazy.” Toshinori replied.

Izuku grimaced, “Yeah, no, really bad idea.” He told Toshinori, “I’m just about to start high school in a few months! That means that it’ll be three years before I can even get into U.A. And another few years before I graduate and can legally be a Hero. Do you really think you’d last that long without the actual Quirk?”

“Shit.” Toshinori joined his successor in grimacing, “No, you’re right. I didn’t think that through.” He looked at his hand, before making a fist, “My injury has been… fairly consistent in sapping my strength over the past two years. But if I lose One For All, it’ll definitely vanish faster. By the time you’re close to graduating high school, I believe I’ll be down to three hours per day, assuming no further complications.” He sighed, wishing he had been just that bit smarter in his fight with All For One two years back. His hotheadedness from his early years had bitten him on the ass at the worst moment. He thought he’d be better… but all that bastard had needed to do was taunt Nana and he had flipped his lid. “I won’t make it to your official debut regardless. I’ll have to retire before then.”

“Then I think the best thing to do would be to have this be my high school project.” Izuku said, “I can clear out an inner area that we can use to spar and so you can teach me, and I’ll work my way outwards. We can spend the last couple of months before I graduate high school working on One For All.”

“Good plan.” Toshinori gave him the thumbs up, “I’ll make the adjustments.” He took back the notebook he had given the boy, only slightly irritated that he hadn’t thought of any of this himself. “In the meantime,” He grinned, “Get to work, shōnen!”

“Yes sir!” Izuku yelled before leaping into action.

Toshinori laughed as shadowed his young protégé, making sure that he knew the proper lifting techniques and that he understood his own limits. He’d leave him alone once he was sure Izuku wouldn’t accidentally hurt himself, but that would probably take a while as he acclimated to actually using his muscles and body in unfamiliar ways.

The time passed quickly, with Izuku making excellent progress for just the first day. Finally, Toshinori called time, “Alright, we’re done for the day!”

“Really?” Izuku straightened up from where he had been reaching for a long pipe, “There’s still daylight. I don’t feel so tired yet. I feel like I can keep going.”

“Yes, but there will be more to this training than just lifting junk or sparring every day.” He bulked up into All Might, “After all!” He boomed, “You have your Quirk to exercise too!”

“E-Eh?!” Izuku looked bewildered.

All Might put on his cheesiest smile and gave his protégé a thumbs-up, “Go lay some pipe, young Midoriya!”

He wished he had a camera for Izuku’s spectacular spittake.

-]|[-

Izuku breathed deeply, a smile on his face that would take quite some doing to remove. He was here. He had done it! U.A. was sitting pristinely in front of him!

Several years had passed since he had met his mentor, and he was a completely different person than he had been even back then, and completely unrecognizable from the beaten-down and bullied kid he’d been before Incubus had awakened. He’d always thought he’d be fairly short, since both of his parents (or rather, his mom and his sperm donor) were short themselves… but apparently his grandpa on his mom’s side (who he unfortunately never had a chance to meet) was a giant and he inherited some of his height after a huge growth spurt. He wasn’t nearly as tall as All Might, but that man made giants seem small. Still, 185cm was very respectable! His body was muscled and lean, being more of a swimmer’s build than All Might’s body-builder type. And right now, after all the time and effort he put into his training (and all the improvements to his mental state that only regular sex with beautiful ladies could induce), he stood with confidence. He felt ready for anything U.A. could throw at him!

There was just one problem.

The second he laid eyes on the first girl on campus (a beautiful and bubbly periwinkle-haired woman stretching U.A.’s uniform to the breaking point) he realized that he could currently substitute a glass cutter with his dick. ‘Ugh, this was such a bad idea.’

For the first time in years, Izuku had gone more than a week without sex. Hell, he’d gone several without sex. Upon taking One For All, he and All Might had spent so much time sparring and getting him used to his Quirk that Izuku had actually been too exhausted for his Quirk to do much of anything. Izuku had even tested out of his final year of high school a few months early just to have the most amount of time possible with All Might while he still had the strength to teach what only he could.

And now Izuku was definitely regretting it and hoping beyond hope he’d be able to focus long enough to just take the damn test. Of course, his musing was cut off by the explosive asshat he’d been dealing with for over a decade, “Out of the way, Deku!” Bakugō snarled, actually shoving him as he passed. Ever since he had saved the asshole, he’d been insufferable.

Izuku had definitely not been paying attention and had tripped when he’d gotten shoved. He threw out a hand to catch himself but apparently needn’t have bothered.

“Gotcha!” He froze in midair, simply floating there for a moment.

“Woah! This is cool!” He got spun around and then laid eyes on her for the first time. His pupils dilated and he could feel his Quirk acting like a caged beast inside of him, wanting to be let out.

The girl was absolutely gorgeous, but she was also as cute as a button. She had brown hair which reached down to her back, chocolate eyes, and literal blush marks on her cheeks. Blushing which was getting darker as they both looked at one another. “S-Sorry!” She put him on the floor and stuttered as she apologized, “I used my Quirk on you without permission.” Oh gosh, she was adorable.

Izuku wanted her like he had wanted no one else he’d ever met. He put on his best roguish grin, “No worries! You saved me a faceplant!”

“Yeah, what the heck was wrong with that jerk, Deku-kun?” She asked him and blanched as his expression dimmed, and he visibly went ‘calculating face’ on her. “O-Oh, was that not right? That’s what the jerk called you.”

“Ah!” Right. She couldn’t have known his name. He never gave it to her. “Midoriya Izuku.” He replied, giving her a smile.

‘Phew! Almost made a bad impression!’ She thought in relief, not knowing why she was so immediately interested in this boy with such fluffy green hair. “Uraraka Ochako!” She greeted him cheerfully, “And sorry about that! What is that guy’s problem, and why did he call you ‘Deku?’”

“He’s pissed he peaked in elementary.” Izuku informed her helpfully, “His personality is a sewer.”

“Yuck.” Ochako wrinkled her nose.

“Yeah, and my Quirk was one of those late bloomer types, so we all thought I was Quirkless when we were young. He made up an ‘alternative reading’ for my name’s kanji to say I was useless like one of those wooden dolls.”

“Wow, what a fucking asshole!” And Izuku’s image of her as a pure angel died an amusing death. “I hope he fails!”

“Mood.” Izuku quipped, “Though I doubt it. He’s actually pretty good with his Quirk and is quick on his feet.”

“Drat.” She beamed at him, “Well, hopefully if he passes we won’t have to deal with him, right?”

“Damn straight!” Izuku laughed. “Shall we?”

“Mm!” Ochako nodded, and they walked towards the building, “Honestly, I don’t get it. It’s not even creative! I actually thought it was some weird way to say ‘Dekiru.’ You know… ‘you can do it!’” She punched the air lightly. “I thought it was cute.”

“Huh…” Izuku froze a step, “Never thought about it like that. Almost like a Copernican revolution…” He muttered before continuing on.

“…Co…pe?” She looked befuddled.

Izuku laughed, “Well, I’m certainly not picking it as my Hero name or anything, but I guess I don’t mind you calling me that.” He grinned a little, “Not like anyone other than him calls me that anymore.”

She looked excited for a moment, before her face fell. “I don’t know… Feels kind of wrong to use a mean name like that as a nickname, even if you don’t mind.”

“You could always pick something else then.” He winked at her, “Maybe Dekun if you like it?”

She beamed at him.

…

Izuku got off the bus as he arrived at his designated test site, taking a deep breath of the fresh and clean air of U.A.’s campus. All around, the examinees were chatting confidently, though with his experience, he was well aware that it was more than a bit of bravado. Everyone here was nervous even if they were trying not to show it.

His eyes widened and he smiled as he caught sight of a familiar figure. It was Ochako! She looked to be one of the more nervous ones of the bunch, so he started walking over to her.

“That girl seems to be doing some kind of meditation.” Someone behind him said before grabbing his shoulder, “Why are you here?” It was the same dickbag from the auditorium who had tried to admonish him for ‘not taking things seriously.’ He had an intense glare on his face. “Hoping to interfere?”

Izuku had long since stopped taking any shit from his classmates. He wasn’t going to take it from a stranger. “Why don’t you mind your own damn business.” He glared back, whipping the boy’s hand off his shoulder. “And stop taking out your own damn nervousness on everyone else.” He walked away as the boy gawked at him. “Hey Ochako.” He smiled at her.

She blushed prettily as she turned around and saw him. “Oh, you’re here!” She said excitedly. “It must be fate!” She declared adorably and behind them, the intense boy flushed as he realized his mistake.

“You ready for this?” He asked.

“I- uhh, I’m a little nervous.” She admitted bashfully.

“Well, don’t be!” He told her. “With an amazing Quirk like yours, you’ve got this in the bag!” Izuku held up a fist in front of him.

Ochako beamed at him once more, “You know what? Yeah! We’ve fucking got this!” Again, the words and the cuteness almost gave Izuku whiplash. She fist bumped him.

Izuku chuckled, “Want a head start on the action?” He eyed her slyly, “Then just remember. There are no countdowns in real life.” He leaned in as her eyes widened, “And if you want a lift, just hop on. I’m super fast.”

She blushed bright red but nodded shyly, not sure why she felt like she had known him for so long.

“AND START!” Present Mic was nowhere to be found, and yet his voice hit all seven testing areas at once.

Ochako’s eyes widened as Izuku bent his knees and offered her a piggy-back. She leapt on, her face getting even redder as she felt all of his tight muscles. And then he became covered in green electricity and Ochako’s world exploded. She moaned and ground into his back, feeling like she had just spent the last hour edging herself. She didn’t get a chance to say anything as the world blurred. “Oh, holy fuck!” She yelled as she learned ‘super fast’ was actually ‘holy shit wtf!’

He came to a stop inside a whole squad of two-pointers. The robots even took a moment to detect them. “Gravity!” Izuku yelled.

“Right!” Ochako valiantly tried to force down the intense feeling of lust his lightning had generated in her. She slapped her hand onto the two-pointer. Izuku then leapt around, dashing to and fro as she slapped bot after bot and caused them to lift into the sky. Izuku then put her on the ground (much to her relief as the feeling of impending orgasm dimmed considerably) and leapt up at one of the hopelessly flailing bots.

He palmed it with one hand, “Time for a fastball special!” He cackled gleefully as he chucked it across the entire city. The blue-haired boy had been about to kick a three-pointer when Izuku’s fastball smashed into it, shattering it into a thousand pieces. Said pieces continued onward, shredding three-pointer after three-pointer and stealing all the points he had been about to collect.

Ochako had meanwhile decided the nine remaining bots were high enough and tapped her fingers together. They dropped like stones, crashing to the ground and shattering.

“Nice job, Ochako!” He grinned at her as he landed. “Great teamwork!” He did not mention her little… incident. ‘Holy shit, what did One For All do?!’

Ochako was glad he didn’t mention it, because she wanted to die. She had dry-humped his back while moaning lewdly! Where was a convenient hole for her to crawl into!? “Y-Yeah! We’re a great team!” She said peppily, though her tone was a bit forced.

‘Better give her some time to cool down!’ Izuku thought to himself. “Well, good luck, Ochako! I better see you at U.A. in a month!” He declared before he was gone in a flash of lightning.

Ochako was both sad and very happy to see him go. She didn’t need this distraction right now. She clapped her cheeks to float and kicked off a downed two-pointer towards a squad of three-pointers.

Izuku grinned as he moved through the city, unable to believe how good it felt to use One For All. He couldn’t manage more than ten percent of the Quirk even with all of his training, but he had very quickly noticed that his ten percent was more like All Might’s forty percent. They had no idea what the hell was going on there, and All Might had decided to get them both tickets to the upcoming I-Expo! Apparently David Shield would be there! He was so excited!

He smirked as he came across a one-pointer. He hopped onto its back, grabbed its gatling-gun arm, forcibly maneuvered it, and then squeezed the conveniently-placed trigger. The gun immediately went out of control, shredding other villain bots around him. His eyes widened, ‘How the hell does U.A. keep these things safe?!’ He asked himself incredulously. If he had the time to actually examine them, he would realize these things actually had two types of ammo. Without interference from students doing exactly what he did, they fired relatively harmless rubber balls.

With his targets eliminated, Izuku punched down and destroyed the bot. He leapt off and then ran up the side of a building to get a bird’s eye view of the city. He saw a student who looked like they were about to get overwhelmed by a group of two-pointers and moved like lightning towards them. “I’ve got ya!” He declared, a smile on his face. The young woman blushed as he tore the robots apart and then helped her to her feet. She didn’t get a chance to thank him before he was gone again.

The test continued apace, and throughout the test, the proctors watched with pride.

…

“So how do we grade their little tag team?” A sensuous voice asked with an eager grin on her face.

A squeaky voice belonging to a creature that might have been a mouse, a dog, or a bear laughed, “They were essentially complete strangers-” He had already checked both their profiles to confirm, though the footage he’d watched of everyone coming in had already told him as much. “-before the exam, so to see such good teamwork already is a delight. Two points for each two-pointer to both. One three-pointer for Uraraka Ochako.”

“Excellent! I can already tell those two will be cute!” The sensuous voice declared. ‘Especially with how she reacted to that lightning. How entertaining!’

‘That’s the way, kid.’ Toshinori grinned up at the screens.

Another person spoke up, “Such a wide battlefield and the time limit brings out the best in them.”

Another picked up from where he left off, “Those who can assess a situation in moments; Information Gatherers.” An image of a tall prospect with what looked like wings and other appendages stood on top of a building. It changed to a young woman with vines for hair that was strung up and swinging from lampposts. Izuku appeared again, racing up a building to take in the city.

A ‘manly’ voice continued, “Those who will never be late to the party; Mobility Experts!” A video of the intense boy with glasses crashing through a three-pointer with a kick appeared, followed by one of Izuku blitzing to save a young girl.

“Those who can cope with any situation; Decision Makers!” The blonde kid was flamboyantly blasting through three three-pointers with his navel laser. It switched to a girl with a really long tongue grabbing a lighter one-pointer and using it as a bludgeon. Another switch showed a very tall fawn-haired girl panicking as she was surrounded by three pointers. They all blasted her… only for their attacks to slip right through her and damage one another. The giant girl vanished, replaced by an impishly-smiling version of her several feet away that was normal-sized and blowing the destroyed three-pointers a mocking kiss.

The woman with the sensuous voice returned, “And of course… combat experts. The natural born warriors.” An explosion engulfed the screen before clearing, revealing Bakugo Katsuki standing amongst the shredded husks of half a dozen enemy bots. It then switched to Izuku again, passing through a squadron like the Shinigami was possessing him.

“The abilities needed to preserve peace in our cities are judged by the points they earn.” The squeaky voice said.

“Quite a crop we have this year, huh?” The female said, followed by the sound of her licking her lips.

“Nah, no way to tell yet.” Toshinori finally spoke, “This should tell us more…” he flipped open the protective casing of a button labeled ‘Yaruki Switch,’ and firmly pressed it. Immediately, pandemonium started erupting on the screens as the titanic final villain appeared. It was a behemoth taller than most of the buildings and was capable of casually pushing them over. Dozens of student prospects simply started turning tail and running as the city broke around it, passing by their fallen examinees who weren’t quite able to get away with barely a glance in their direction.

“People show their true colors when they face that thing.” One of the males replied to him.

The One For All wielder’s grin hadn’t vanished from watching his pupil, and likely wouldn’t for several hours too, “Let’s see what they’re really made of.”

…

“Holy cow, that’s big!” Izuku gaped at the giant robot. “And-” He frowned, watching as it went absolutely wild. “Someone’s going to get hurt.” He said as examinees raced past him without so much as looking to see if anyone needed help. “Again, how the hell does U.A. keep the examinees safe with it raining concrete?!”

And like he was a prophet, he heard a familiar voice. “H-Help!”

Izuku zeroed in on Ochako. She was on the ground, face visibly in pain. Fallen concrete covered her legs, and she tried to reach back to try to float it all off of her. She couldn’t reach; her body was trapped in such a way that she could only get a few fingertips on it.

Every cell in Izuku’s body shifted to attack mode. He surged forward, appearing in front of the behemoth’s faceplate with his fist cocked back. “SMAAAAASHHHH!!!” He roared, punching so hard the zero-pointer’s face indented back roughly two meters. Explosions started to ring out as it fell back. The shockwave ripped the concrete below right off Ochako. As then Izuku began to fall, ‘Shit!’ He thought as he felt his legs and his arms. ‘I went overboard!’ It hadn’t been by much. Probably only twenty-percent, but that was double what he was used to. He could feel muscle tears and hairline fractures all over. He was going to have a tough time landing like this.

He looked down and his eyes locked with Ochako’s. She must have seen that something was wrong because she scrambled and climbed on top of a gigantic missile pod from one of the three-pointers. It floated up and she met him mid-fall, basically high-fiving his good hand. Their fingers laced together. “I’ve got you!” She gasped out as he managed to swing himself onto the missile pod.

“T-thanks.” He grunted in pain as he settled atop it. The head slowly sank before touching down.

Ochako tapped her fingers together, “R-Release.” She managed to get out, before her cheeks bulged. She clapped her hands to her mouth, but it was too late. She puked all over the side of the pod.

‘Must be her Quirk’s downside.’ Izuku thought, grimacing atop the pod. “You okay?”

She gave him an exhausted smile. “T-Thank you… for coming back for me.”

“Of course.” He smiled at her. “And thanks for saving me back.” She beamed at him as Present Mic announced the end of the exam.

Soon, Recovery Girl came by, “Dearie me, what happened, young man?” She asked him.

Izuku grimaced, “Wasn’t thinking and used more of my Quirk than I was used to.”

Ochako blinked, “…Wait, more than you were used to?” Her eyes went wide, “Does that mean it can go even higher?”

Izuku smiled sheepishly at her, “Yeah, uh, that was just twenty percent. I was using max ten during the exam.” Ochako gaped at him owlishly.

“I see.” Recovery Girl mused, ‘So, that big lump finally passed it on, hmm?’ She extended her lips and granny-kissed Izuku, followed by Ochako.

“Oh!” Both of them glowed and their injuries vanished. “Oh, that feels so much better.” Ochako exclaimed as Izuku jumped off the pod. He smiled up at her and held out a hand. She blushed as she got off of it too and was helped to her feet. “Thank you, Dekun.” She mumbled as she gazed at him. Now that she didn’t have an exam to worry about passing, she was feeling acutely hot from the memory of his lightning. She just didn’t know why she was aching for him like this. She’d never reacted like this to anyone!

And Izuku could feel it. Could feel the building desire within her. It was causing his own to spiral. He smiled at her, “Want to grab something to eat to celebrate making it to U.A.? My treat.” He winked at her.

She flushed again, “Y-You don’t know that we passed.” She mumbled, looking away.

“Nah.” He said, “We kicked ass! We’re both in for sure!” He told her.

Her heart fluttered, both at his words and his smile. He was so confident he was pulling her up too. “Okay!” She said, putting some pep in her voice. “Let’s go get lunch!” She forced confidence into her smile.

The two walked away, uncaring about the murmurs that followed them from the other examinees.

-]|[-

As Izuku walked her home (and by home she meant the very tiny apartment that her dad had constructed about a year ago which they had a five-yen lease for. She loved her parents so much!), Ochako still couldn’t understand why she was aching for him so badly. She had never even been on a date before this! Not that boys (and a few girls) hadn’t tried, but she had just been so focused on doing her absolute best to become a Hero that she had never given anyone the time of day. She had actively skipped going to parties and such when invited just to help out with her parents’ construction business! She needed to be a Hero! She didn’t have time for boys! She barely had time for ‘me time!’

Maybe that was why? Maybe now that the exam was over, she was just allowing herself to relax a little bit? She had been planning on getting some… alone time with one of her toys when she got home, regardless of how she thought she did. She had even packed it for this trip from Mie…

And then Midoriya Izuku had stampeded his way into her thoughts with that handsome smile and stupid kindness and- She flushed again, looking down and concentrating on putting one foot in front of another, acutely aware of her fingers laced with his. ‘It’s not fair!’ She wailed mentally, ‘He even took me for mochi!’

“Everything okay, Ochako-chan?” Izuku asked, giving her that stupid, sexy smile that did stupid things to her heart again.

“Y-Yeah!” She said almost mechanically, “W-why wouldn’t they be?” He chuckled, giving her a look that was too knowing for her own good. Soon enough, she found herself in front of her door. It wasn’t much, but it was her mom and dad’s hard work that had built it! And inside was her vibrator, whose motor she was going to burn out as soon as she was alone. Her reward for all her hard work over the past months getting ready. “Thank you for walking me, Dekun.” She said, and, not knowing what had possessed her to be this freaking forward, she stood on her tip-toes to kiss his jawline.

“You’re wel-” Their lips met as he turned his head, knowing exactly what she had worked up the courage to do.

“Mhmph!” Ochako’s eyes bulged as her sweet peck turned into a liplock. Her arms went around his neck. ‘Stupid Ochako! Pull away!’ She instead deepened their kiss before feeling his tongue against her lips. She parted them to allow him entry, releasing a muffled moan against his lips. ‘He-he’s going to think I’m such a slut!’ She wailed mentally as his hands found her ass and gave her thick cheeks some experimental squeezes.

And then she was in the air, her legs around his waist. “Ochako…” He breathed into her ear, sending shivers down her spine. He nibbled on her earlobe as she shuddered. “Maybe we should take this inside?”

She nodded dumbly, sliding her backpack off her shoulders like it had offended her. She hurried to open the pocket that held her keys, which Izuku took and unlocked her door in smooth, quick motions. He stepped through into her domain, finding that it truly was tiny and sparsely furnished. There was a small chair, a bed, a kitchenette, and a bathroom. He closed the door, locking it behind him before sitting on the small but comfy chair.

“Dekun-” Ochako got out before his lips were on hers again. “Mmph!” She started to grind wantonly on his lap, desperate to put out the fire that had ignited between her legs.

“So pretty.” Izuku said as he pulled back, opening her warm jacket and flinging it onto a clothes hanger. “My Ochako…” His green eyes were glowing as he reached up to her button-up shirt and grabbed the lapels, before ripping it open.

“Ah!” She let out a squeak of shock as her frumpy bra was revealed to him. It wasn’t her fault! She hadn’t even thought she would need anything sexy today! The buttons of her shirt clattered around them. “Dekun!” She whined as he started suckling her nape, before slowly moving down and trailing kisses down her right breast. Her bra was in the way! She wanted his lips on her properly! She reached behind herself and found her shirt in the way! He hadn’t removed it completely! And then, he used her own shirt to bind her arms behind her. Her heart was pounding as he locked eyes with her.

“Bad girl.” He murmured, seizing her chin with his other hand.

Oh. He was taking total control, wasn’t he. Her pupils were tiny pinpricks as she panted atop him. “Dekun please…” She mewled.

“Patience, ‘Chako.” He murmured back, a somewhat evil smile on his face. “I want to unwrap my present myself.”

Ochako hadn’t even known that this would be so hot. She was totally at his mercy with her arms extended behind her. “I’m all yours, Dekun! Please!” She begged, her heart racing in excitement.  He smiled and his free hand found her skirt. He popped the buttons and the garment loosened immediately. Ochako touched her fingers to her hands and started to float up, desperate to have it removed. He slid it down her legs and tossed it on the floor, before freeing her hands to grab her hips, keeping her from floating away. She immediately touched her fingertips together to end her Quirk’s effects. But she didn’t try to take her shirt or bra off again.

“Good girl.” Oh, why did those words make her heart flutter like that? He traced a feather-light touch with one finger up her thigh and between her legs. “Oh, you’ve soaked this pantyhose, Ochako.” He teased as his middle finger found her pussy and traced a line up to her clit.

“Dekun!” She was almost sobbing for relief at this point. But he removed his hands from where they belonged, and she let out a keening whine. He grabbed her shirt and finished removing them, before popping her bra’s clasp open. The second he did so, her chest forced the front forward a few inches. She blushed, wondering if he would like how big they were. She had always been a bit… bigger than most of her classmates. She hoped they wouldn’t get in the way during Hero work…

He removed it from her body and flung it away. “So beautiful.” He said as he gazed upon her pink, puffy nipples. He reached up and started massaging her breasts. “So soft.” His lips found her right nipple while his fingers found her left.

“Ah!” She squeaked as he began to suck. They weren’t that sensitive in her experience, so she hoped that he would move between her legs soon.

He agreed. Her sensitivity wasn’t all that high. But with a mental smirk, he thought to himself, ‘Let’s fix that.’ His hands began to glow pink as he massaged her breasts.

“Ah!” Ochako’s eyes widened again as her breasts started to feel so good. He resumed nibbling and pinching on them, giving both of her boobs his love. ‘H-How is-’ She yelped as she felt her muscles start to tighten. ‘How is he doing this?!’ She wailed as she felt pleasure start to build inside her. ‘I’ve never- not with my boobs- Oh my gawd!’ Her world dissolved into pleasure as she rocked on his lap. Her entire body quivered as she came. When it ended, she panted, sagging against him. ‘He-He made me cum with just my boobs! Oh Ochako, you stupid idiot! What have you gotten yourself into?’

He stood, carrying her from their seat to her mattress. He started kissing his way down from her breasts, then her belly, and then his hands seized the waistband of her pantyhose and her underwear. And then with one smooth motion, he peeled her soaked undergarments off of her. Ochako’s legs were stuck in the air as he got them off her and tossed them aside.

And then Ochako came to the conscious realization that she was completely naked in front of a boy. She hid her privates with her hands, a massive blush engulfing her face. ‘Oh no! All my hair!’ She was so embarrassed!

Izuku smiled knowingly at her, kissing her hands and parting them to expose her. “Don’t like the hair?” She mewled in embarrassment, pressing her palms to her face. She hadn’t even trimmed! “How about a magic trick?” He asked, his smirk widening as he grabbed her legs and positioned them into the air. She looked through her fingers quizzically, before he pressed a glowing palm between her legs. She had a strange feeling and then he pulled his hand away.

Her jaw dropped. “Oh my gosh!” Not a single hair remained anywhere on her privates! She looked like she had gotten a Brazilian with no pain at all! “What even is your Quirk, Dekun?!”

He chuckled, “I think that’s a question for later, don’t you think?” He teased, before sticking out his tongue. And Ochako’s face reddened as more and more tongue escaped his lips, until about six inches hung out. Before she could even react as it snaked back within his mouth, he dipped forward and placed a kiss on her lower lips.

“Oh!” Ochako’s heart fluttered as he placed a few gentle kisses on her, before lightly tracing her labia with his tongue. He pressed forward, sucking slightly on her engorged lips. Then his tongue traced upwards and began to vibrate directly on her clit. “OH!” She grasped handfuls of her comforter as he began to suckle on her clit. “Yes! No!” She mewled as she felt him pull away but then felt his long tongue slide inside her. “Oh, oh fuck!” She gasped out as his tongue found her g-spot with unerring accuracy and started vibrating. “FUCK!” She squealed, squeezing her legs around his head. His hands slid up her body and found her nipples. Emerald lightning began to crackle on his fingertips as he pinched her puffy peaks. “DEKUN!” She screamed, raising her hips off the bed and squirting all over him. A stream of fluid that lasted three seconds covered both of them.

She collapsed back onto the mattress, twitching. “So tasty.” He pulled his tongue out of her pussy and licked her clean. He smirked as she stared at the ceiling with glazed over eyes and prepared his next spell. His fingertip had a deep purple glow over it as he pressed it to her asshole.

Her eyes went wide, “D-Dekun!” She yelped as she felt energy flood her insides. She shuddered at the feeling before it went away, leaving her oddly empty. He gazed upon her cute, freshly bleached asshole eagerly. “Wh-what did you-” Her eyes widened and she let out a scream as he wriggled his tongue slowly into her ass. “No!” She mewled, “Th-that’s dirty!” And wasn’t it supposed to be painful with no prep!? What the heck was going on?!

Izuku paid her no mind as he continued eating her ass. She tried to push him away, but he grabbed her hands and forced them flat to the mattress. And Ochako, to her disbelief, began moaning. It felt good. Why did it feel good?! This should have been disgusting, but it was turning her on almost as much as her pussy had! ‘Oh my gawd, I’m going to cum! He’s going to make me cum from my ass!’ Her hips rocked as he let go of her hands again and grasped her thighs instead. She should have been pushing him away, but it just felt so good! Her fingers found her clit and began to rub. “Dekun! Dekun!” She chanted as she began to tremble. “DEKUN!” She screamed as she came again, her backdoor trying to crush his tongue as her entire body clenched.

She was dead to the world for a few moments as she came down from her high. She was just gazing blankly at the ceiling. Izuku grinned as he pressed a finger a few inches below her belly button. The site began to glow, before an intricate heart-like tattoo formed there, glowing bright pink. He began to strip as well, finally removing his own clothes.

She finally came to as he undid his belt. “W-Wasn’t that… nasty?” She asked hesitantly. She hadn’t ever been brave enough to experiment with anal. She had heard it felt good, but she hadn’t even wanted to even try it when she read about all the prep work it normally took. “Y-your tongue was in…” She blushed, unable to even finish her sentence.

“That’s what the spell was for.” He grinned smugly at her. “Completely cleans you out and lubes you up. It’s actually pretty tasty.”

“Oh,” she said dumbly, unable to take her eyes off his chest. Because of her squirting, he was all wet. And as she watched a bead of her cum trail down his abs, her eyes locked onto his crotch as he dropped his pants. ‘I’m going to die.’ She said dumbly, her pupils like pinpricks as she stared at the monster between his legs. ‘I-it can’t fit!’ She wailed dumbly as he settled between her legs and allowed his cock to slap down onto her belly. It completely covered her belly button with room to spare.

“You ready, ‘Chako?” He asked her, grinning at the utterly scaroused look on her face.

“No!” She yelled while nodding rapidly. “It won’t fit!”

Izuku chuckled as he jerked himself a few times, his dick getting wetter and slipperier as he used another of his spells. He then began to thrust, using his thumb to press himself down so he would rub along her clit. “It’ll fit, Ochako.” He promised her. Her womb tattoo glowed as he drew his hips back farther and placed the head against her puffy lips. They spread apart as he pushed, engulfing his head, her tunnel already squeezing down on him.

He bent her legs back so that her ankles were around her ears and then pushed all the way in with a wet CLAP. “AHHHH!” Ochako squealed as he pressed his hips against hers. Her stomach was distended upwards. There was no pain. How the hell was there no pain?! He had a club for a cock! But she could only feel pleasure as she stretched to the brink to accommodate him.

He kissed her, muffling her pleasured moans. She was just so tight around him. The tightest he’d ever had! He pulled back to whisper in her ear, “I told you it would fit, Ochako.”

“Dekun.” She whimpered, “Fuck me!” She begged. “I want more! Give me your cock, Dekun!”

Izuku pulled his hips back until just the tip of his cock remained in her needy, grasping pussy before slamming down once more. “Is that what you want, ‘Chako?”

“YES!” She wailed, “Make me yours!”

And so he did, pulling back halfway and then descending with a wet clap, again and again.

PLAP PLAP PLAP PLAP

He set a hard pace with his mating press, giving it to her as hard as she could take. Her asshole started to wink open as he drove himself into her again and again. Even without doing any fun things like raising her sensitivity, she was just so responsive. But he wanted more. He wanted her squealing and begging. Her womb tattoo glowed again and she screamed, desperately hugging him and scratching his back as her pleasure started to build even more rapidly. It took her less than twenty seconds before she came explosively once more.

He let out a moan of his own as her pussy did its level best to crush his cock. Finally, she relaxed and fell limp, but he showed no mercy. He pulled back a bit so as to give her body a break with some regular missionary and resumed his furious pace, driving deep into her depths again and again. And as he felt his first orgasm start to come, he smirked. “I’m close, Ochako.” He whispered in her ear. “And I’m going to dump it all into your pussy.”

Her eyes widened as she realized he wasn’t wearing a condom. “N-No! Not inside!” She mewled, knowing that even with her Quirk, she could do nothing to stop him. And worse… her pregnant-sex kink reared its ugly head. “I-I’ll get p-pregnant!” Her breath hitched at the word.

“You sure?” He teased her, “Wouldn’t it be so nice to hop on my cock with a big, swollen belly?”

“Fuck!” She squealed as he continued to pound her. “N-No! I-I want to be a Hero!” She protested weakly. “I c-can’t be a mommy!”

“Oh, but you’d look so sexy pregnant, Ochako~” Izuku smirked, “I can’t wait to taste your breast milk.”

“P-Please!” Ochako wailed.

“Please what?” He asked as he sped up, the end close, “If I stop now, neither of us get to cum. I’m so close, ‘Chako.”

“Pleasepleaseplease!” Ochako wrapped her arms around his neck and her legs around his waist.

Their lips met in a desperate kiss as Izuku pressed his cock as deep as it would go in her. In a moment, her womb was flooded with his semen. He groaned as weeks’ worth of his semen was dumped into his needy lover. He came so hard that some of it started to spurt out of her pussy. Enough that other guys would have called it a whole orgasm.

And with his Quirk working overtime, Ochako experienced every drop of it entering her and sending lightning through her body. “AHHHHHHHH!!!!” She screamed into his lips as she had the biggest orgasm of her life. She clung to Izuku so hard that she lifted herself off the mattress, grinding her pelvis into his. Her entire body was spasming from the sensory overload. Pleasure flooded her so hard and for so long that she whited out.

Izuku panted atop her as she fell limp onto the mattress below. Every once in a while, she twitched as an aftershock hit her. ‘Okay, while I really shouldn’t have gone so long without, that was so fucking worth it.’ Only problem was he was still as hard as a rock. And she was out of it. The lights were on, but no one was home.

He started gently kissing Ochako, whispering sweet nothings in her ear as he coaxed her back to life. When she finally came too, she began to shake, “Oh god, y-you really cam-”

“Don’t worry.” He chuckled as he pulled back, tapping her swollen belly and directing her attention to her new womb tattoo for the first time.

“What is that?!” She yelped, looking at it with shock.

“This little baby acts as birth control… among other things.” He smiled down at her, “We won’t have any accidents, Ochako. I wouldn’t do that to you.”

Ochako stared at Izuku with shock, and then with relief. “Oh thank fuck.” She closed her eyes, “T-that was so fucking hot but once it stopped…”

“I knew it would get you going like nothing else.” He murmured to her, kissing her gently.

“What, is your freaking Quirk hentai logic or something?” She asked between sweet kisses.

“Or something.” He smirked and slipped inside her once more.

She yelped, “Y-You’re still hard?!”

“Oh ‘Chako.” He chuckled and whispered into her ear, “I haven’t even started.”

And from then on, Ochako’s world devolved into mind-numbing pleasure. He took her again, and again, and again. Missionary again. Cowgirl. Against the wall. She even used her Quirk so they could fuck on the ceiling. The only times they stopped was for drinks so that she wouldn’t get dehydrated too badly. Despite knowing she should have been raw from it all, Ochako took his massive cock again and again like a good little girl. Day dimmed and night fell as they made love again and again.

But even this insane, impossible stamina started to run out. Ochako was exhausted. Every time he came in her, she came like she had never come before. Her muscles were sore and now, she was laying face-down on her bed. “Dekun…” She moaned tiredly as he mounted her from behind, his thighs around hers. “I-” Her eyes widened as she felt him squeeze her ass and spread her cheeks, “!” She let out a squeal as she felt his massive rod start to pierce her ass this time. She grunted and clenched her sheets as her asshole was slowly spread out. “Fuck, fuck, fuck!” She chanted as he bottomed out. “My ass! You broke my ass!” She slurred out through the dizzying pleasure.

“You’re doing so good, ‘Chako.” He whispered in her ear. “One last one. I promise.” He said as he nibbled on her earlobe. “My good girl. You love it in your ass, don’t you?”

“Yes! I love it, Dekun! I love your dick! I love you!” She barely knew what she was saying at this point.

He chuckled, “Love you too, ‘Chako, and I’m going to prove it every chance I get. You’re mine.”

“Yours!” She wailed in agreement.

Unbeknownst to Izuku, her womb tattoo pulsed before evolving. More details appeared around the heart, like little wings. He pulled back and held her cheeks as her asshole gaped for him. Izuku pressed forward and speared her depths again. He reached underneath her and started to play with her clit, the barest hint of One For All’s lightning surging through them. He turned down her sensitivity too, wanting to enjoy what he knew would be the last round. He pounded her hard, again and again as she slurred declarations of love at him. Finally, he felt himself clench, unloading himself deep into Ochako’s tightest hole.

SPISHHHHH

Again, Ochako squirted all over her mattress. Her womb tattoo glowed brightly. When she fell limp, Izuku immediately noticed she was out cold. He gently pulled his cock from her ass, frowning in confusion. He had ‘exercised’ his Quirk often enough to know how it felt. He took energy from each woman he had sex with. It was a small amount per woman, but enough that he was far past peak human even before he took One For All. The girls also got something out of it: enough energy and stamina to survive more than one or two rounds with him. He was pretty sure it wasn’t something altruistic, but merely something to not leave him more frustrated than he started. Quite literally, girls who had sex with him got a bit stronger and healthier. He knew that intuitively but had never actually felt a drain before.

For the first time, he had felt her take energy from him in return. And not a small amount either. How the hell had that happened? His confusion worsened when he got up and realized he was still hard and ready to go. He willed the erection away before gazing at Ochako. She was still facedown on the bed with her hips just slightly raised. Sperm leaked from both of her holes. Smiling fondly, he cast a few more spells. All traces of their activities vanished except for their nudity. He didn’t know anyone who cared to sleep in a puddle of mixed cum.

Even the sheets dried themselves! 

He flipped her so that she was on her back and his eyes bulged. ‘What the hell?!’ He gazed at her evolved womb tattoo, ‘I’ve never seen that before! What the hell happened to my Quirk?!’ Frustrated that he wouldn’t get any answers, Izuku went to the bathroom to relieve himself. When he exited, he did something he had never done before. He got into bed with the day’s lover and pulled her into his chest, the big spoon to her little spoon. Ochako’s hand found his and laced their fingers together. He felt an upswell of affection for her as he placed a gentle kiss on her cheek. “Sweet dreams, ‘Chako.” He murmured before extending a tentacle and hitting the light switch.

He knew he wouldn’t get much sleep. After taking One For All, he had slowly started needing less and less of it. But a couple hours with this sexy little beauty in his arms was more than fine. It would give him plenty of time to try to figure out what the hell was so different about his time with Ochako and every other girl he had ever dicked down.

-]|[-

Ochako awoke all at once, startling. Her eyes opened and closed a few times, before she let out a low groan. “What a dream…” She mumbled.

“Was it a good dream at least?” Izuku teased her from behind.

“EEP!” She threw herself in the air, spun around, and landed right back where she was uselessly. She gaped at him. “…It wasn’t a dream?!” She slapped her hands to her face and floated off into oblivion. “EEEEEEEEE!!!!!!!”

Izuku chuckled and grabbed her leg, “Come back to earth, my lovely Ochako.” If anything, her face went even redder as he pulled her back to him. It took her several minutes to calm down and when she looked at him, he smiled gently and brushed her bangs away. “You have questions.” She nodded silently, both fists held in front of her face. “Ask away.”

“WHAT IS YOUR QUIRK?!” She exploded. “In the exam you were all POW and BAM and were WRECKING everything but but-”

He chuckled fondly. “My Quirk’s name is Incubus.”

Her eyes went super wide, “You mean the sex demon?!” She asked, aghast.

“Was really the only thing that fit.” He shrugged, “And before you ask, no, my Quirk can’t generate. Only amplify. If you didn’t like me at all, then none of yesterday would have happened.”

She took a deep breath as she mulled that over. “O-Okay. B-But how does that translate to punching out skyscraper murder bots?!”

Izuku laughed and she pouted at him. “So, basically, everything about my Quirk has to do with sex. I have ‘spells,’ for lack of a better word, like that little temporary tattoo-” She sighed in relief at the word ‘temporary.’ She was fairly certain if her parents ever saw it they would kill her. “as well as passive benefits to ensure my partners have the best nights of their lives. The tattoo doesn’t just prevent pregnancy; it even destroys any STDs if any are present.” Her eyes widened at that insane benefit. Disease-free guarantee! “Plus, I even give my partners some of my own energy and stamina so that I don’t… well… break them. So it’s literally a workout that makes them a bit stronger than they were before.”

Oh. So that was how she hadn’t died last night.

“In return, I do feed on my partner’s energy. Nothing harmful. If anything, the actual sex generates energy of some sort which I absorb. Not really too sure on the mechanics of it, but I collect and stockpile it, enhancing every part of my body.” He could almost visibly see the equations flying around her head.

“…How many girls have you been with, Dekun?!” She finally blurted.

“Yeah, that’s the downside.” Izuku smiled sardonically, “I literally need sex because of my Quirk. Like I need food. Not quite as often as that, but if I go too long without… well, let’s say I only let myself go without once.” Not counting this latest stint. Thank fuck for One For All induced exhaustion. He needed all the practice with it he could get before… He mentally shook his head. “So yeah, I’ve been with hundreds of girls since it first woke up when I was fourteen.” He had, in fact, lost his virginity on doctor’s orders to a nurse.

She gaped at him. “B-but why not stick to one partner?!” She yelled, wondering if she had entirely misread him and he was actually scum.

His expression fell, “Because until I was fourteen, I was Quirkless.” He snarled the word, looking away. “And every fucking person in my elementary and middle schools never let me forget it.” Her jaw dropped as she remembered what he had told her about the name ‘Deku.’ He continued, “Do you have any idea how much it hurt to have a girl in the class next door confess to me one day, set up a date, and then show up with her friends to laugh and throw eggs at me?”

“LET ME AT EM!” She snarled, trying to jump to her feet. He snagged her again, smiling fondly. “THOSE FUCKING BITCHES!” She struggled, but his superior strength won out in the end, and she was left panting. “How could they, Izuku?”

“Dekun.” He corrected her, pecking her on the cheek. She almost started to cry. She gave him a hug and began to cuddle with him. He chuckled slightly, “So yeah, forget the girls in my school. I wouldn’t touch a girl in my district with a ten-foot pole. So I always went elsewhere, using some of my Quirk’s magic to make me look a bit older and to get me into clubs.” He shrugged, “Was always just sex. Made sure to treat the girls right, but they were always aware that was all it was. Especially once I started to really train for U.A.” He chuckled lightly again, pecking her on the cheek once more. “It was very rare for me to even encounter the same girl twice, though when I did it always led to repeats… It feels nice to wake up with my girl for once.”

“Dekun…” Her face was burning. She looked at him hesitantly, “…You don’t think I’m a slut?”

He frowned at her, “‘Chako, my Quirk literally gives me every advantage in the world for seduction. I knew the second I saw you that you’d love anal, even if you had no idea.” Her face somehow got even hotter. “You were a virgin before me. How the hell can you be a slut?” He smirked slightly and reached down. She squealed as he palmed her pussy with One For All’s lightning crackling along his fingers. “Unless, of course, you mean my slut. Do you want to be my slut, Ochako?”

“Dekun!” She mewled, beginning to pant. “D-Didn’t you get enough?”

“Of you?” He purred in her ear as his fingers slipped inside her and started massaging her g-spot. “Never.” He kissed her deep, and she rolled atop him, grabbing his dick and aiming. She came instantly as he slipped inside her.

-]|[-

The next week was spent in full lovey-dovey mode. Ochako’s parents had set up that weird lease at the building they’d constructed for one purpose only: So that Ochako could live in Musutafu for a time and get to know the city in anticipation of her admission to U.A. She had even put the apartment down as her address for U.A. to send her admission letter to, though if she succeeded, she’d certainly be going home to Mie for a few days to celebrate with her hardworking family.

So Izuku did his duty and showed his new girlfriend around the city every chance he got. The first place he took her to was the beach, showing and aweing her with all the hard work he had done to get it clean.

He only wished it was warmer. No one wanted to fuck on a cold beach.

Izuku even brought her home to meet his mom! The petite woman was just so happy to see him with an actual girlfriend. She and Ochako hit it off immediately and he was fairly certain his mom was already designing the wedding dress. Ochako slept in his bed more often than she slept in hers. (Thankfully for his mom’s sanity, she had long-since made sure his room was soundproofed for this eventuality.)

And with the two of them going at it like bunnies every chance they got, Izuku got a chance to see something he had never seen before from his Quirk. Her draining his energy (not even a percent of a percent of One For All, but still a lot of energy for a regular human) every time she drained his balls started to add up. She got noticeably healthier. Her stamina improved. Her capacity with her Quirk improved. Her physical prowess improved. She looked the same as always; his thicc, slightly squishy, beautiful Ochako… but she was just becoming a better version of herself. And it hadn’t even been a week!

The both of them were dumbfounded. The morning he’d woken up with her in his arms for the first time, he invited her to exercise with him. It was a simple run to start things off. He ended up having to redesign his route to take her back home when he noticed her getting tired so he could finish his usual reps. On the third day, she ran two laps compared to the one she had on the first day. She was almost upset about it. “How the fuck is you fucking me better training than actual training?!”

“Are you complaining?” He laughed, hugging her from behind. She devolved into giggles.

And then, on the seventh day after the Entrance Exams, Izuku and Ochako were cuddling on his couch and watching TV when Inko came in screaming. “IZUKU! IT’S HERE!” She practically crawled into the living room.

“My U.A. letter?” Izuku jumped up in excitement.

“Oooh, maybe mine is waiting at home!” Ochako gasped.

“Yes!” Inko smiled at them, “But it looks like yours is here too, Ochako-chan!”

The two late teens looked at the two letters in Inko’s hand. They simultaneously tilted their heads to the side, “…How the fuck?” They asked at the same time.

She took hers and looked at it weirdly. “It really is mine! How did…”

“Nezu.” Izuku almost went cross-eyed. How smart was that tiger quoll? Was he in their walls?! Had he seen Izuku piping Ochako every night?!

“Let’s not worry! Open them! Open them! I’m so excited for you two! I might faint!” Inko exclaimed.

“Please don’t, Mamadoriya.” Ochako pleaded with her.

“You first, ‘Chako.” Izuku pecked her on the cheek.

She breathed deeply before opening it. A small medallion-looking thingy fell onto the coffee table and projected something in front of them. “Am I a mouse, a dog, or a bear?” The mammal of indeterminate species asked, “All you need to know is that I’m the principal!” He smiled, “And I am here to welcome you, Uraraka Ochako, to U.A. University!”

“YES!” Three voices squealed, throwing their fists into the air.

“Yes, yes, congratulations, Uraraka-san! You scored well on the general education exam with an eighty-three.”

“That’s barely passing!” Ochako yelped, her soul almost leaving her body.

“You cut it a bit close but succeeded all the same! And your Heroics Exam went well too! With your partnership with Midoriya Izuku, you scored twenty-three whole points within the first ten seconds! Many of our applicants couldn’t manage that many in ten minutes! With thirty-nine villain points, your entry is guaranteed! But there’s more! You also worked hard to help people in danger, something most of us teachers find even more important! Take an extra forty-five Hero points too! Eighty-four total points earns you second place out of the entire class! Stand proud, Uraraka Ochako, and welcome to your Hero Academia!”

“SECOND PLACE?!” Ochako screamed in disbelief.

“THAT’S MY GIRL!” Izuku picked her up and twirled her around.

“I’m so happy!” Inko added, tearing up. “And proud!”

“Thanks, Mamadoriya!” Ochako beamed at her before grabbing Izuku for a quick kiss. “Come on, Dekun! Open yours! Open yours!” She slapped his shoulder repeatedly.

“Alright, alright!” Izuku laughed as he put her down. He tore his envelope open. “All Might?!”

“Booyah!” The big man laughed as he flexed on ‘camera.’ “Been a while, young man!” Inko and Ochako blinked, looking at Izuku with confusion. “Why am I here, you ask? You’re looking at U.A.’s newest teacher!”

“WE’RE GOING TO LEARN FROM ALL MIGHT?!” Ochako squealed in shocked joy.

Izuku grimaced slightly, though he hid it well. He knew full well that wasn’t going to be quite as she expected it.

“So now let’s get to the good stuff! A ninety-eight percent on the general education exam! Well done, my boy!”

What the hell had he gotten wrong?! Ochako and Inko cheered and hugged him, drawing a smile to his face.

“Yes, congratulations! But where you did well on the general exam, you knocked the Heroics exam right out of the park! Ninety-one whole villain points! You beat the next highest by double digits, young man! But U.A. isn’t some B-Tier University that idolizes blind violence! We’re a HERO UNIVERSITY! And that means that saving people counts just as much as how well you can wreck a robot! And that means U.A. has a new record holder! You got the maximum number of Hero points possible! A full eighty! And that leaves you with a total of a hundred-and-seventy-one points! Endeavor’s old record is currently crying in the fetal position!”

“YOU MORE THAN DOUBLED MY SCORE!” Ochako screamed in shock.

Izuku sat numb. He had beaten Endeavor’s record?! HOW?! That record had stood for over twenty-five years!

“I’M SO PROUD!” Inko wailed, hugging him tight. “Gosh, I can’t believe it! After everything…”

Izuku hugged his mom tight. “It’s okay.”

“It’s NOT!” Inko looked at him tearfully, “I… I let my despair rule me for so long. I-I couldn’t even comfort you when…”

“Mom.” Izuku kissed her brow. “You were the only one in my corner. The only reason I stayed sane until my Quirk came in. Don’t do this.”

She cried, hugging him tight.

Ochako joined in on the hug, “Congrats, Dekun.”

“You too, ‘Chako.” He gave her a sweet kiss.

“I’m going to call my parents and let them know I made it.” She said, before grabbing her phone and running out.

“And I’ll start making katsudon!” Inko said, fire in her eyes.

Izuku grinned, “I’ll join you. I’ll make my Mochi some mochi.”

“AH! AH! AH!” Ochako cried as they had their real celebration. “Dekun, I love youuuuuu!”

“I love you too, Ochako!” Izuku let out a groan as he held her hips tightly, driving his cock as deep into his lover as it would go. He felt his sperm welling up, ready to flood her womb for the tenth time that night. But something was different. As always, he had felt that small drain every prior time that night. But this time, it seemed stronger than usual. Something closing in on a small percentage of a percent of One For All.

“S-Something is coming!” She got out, and they both could feel it. Something was different.

He started rocking faster, making his girlfriend squeal louder as he lifted her hips up. Her womb tattoo was fully visible (and, to his disbelief and her ire, it had stopped going away even as soon as their second sex marathon) and it caught his eyes as it began to glow. He felt possessed as he continued to pound her, unable to stop even as the tattoo began to evolve before his eyes. Something that surely would have distracted him on a normal day. A swirl appeared in the center of the heart, and starbursts started appearing around the ‘wings.’

Izuku groaned, spilling into her. She clenched even harder than usual around him, his sheets grasped so tight that she tore them as she shook in place. Her eyes rolled into the back of her head and then a pink glow blasted away from her.

Instantly, every single item in his room, the bed and them included, began to float upwards. “WOAH!” Izuku yelped as he started to fly. “Ochako! Ochako!” He yelled, but she was out of it. He didn’t want to, but he began to lightly smack her cheek. “Ochako! Wake up, sweetheart!”

“Whuh?!” She shook her head as the lights came back on behind her eyes. “What?!”

“Look!” Izuku waved around them.

She looked around with wide eyes. “What the fuck!? How did my Quirk-” She shook her head and pressed her hands together, “Release!” Nothing happened. “Release! RELEASE!” She panicked as nothing continued to happen and she looked at her fingertips in betrayal. “My fingerpads! They’re gone!” She screamed shrilly as she started to hyperventilate. “WHAT HAPPENED?!”

“Calm down, Chako.” Izuku ordered. “You did this. I saw it! Your Quirk isn’t gone. Concentrate and bring everything down.”

Ochako slowed her breathing and took a few deep breaths, before closing her eyes. Her Quirk felt… felt more tangible than it ever had before. She concentrated on the feeling, more powerful than it had ever been. And she could feel everything. Including, to her eternal embarrassment, Inko panicking in another room. In moments, everything floated gently down before she disengaged her Quirk from the objects. When she was done, she panted. “What… the fuck…” She gasped for breath.

Izuku let out a confused chuckle. “I…” he made a face. And then he held his hand out. A green glow appeared on his fingertips, and his clock began to float upwards.

The two stared at it in complete disbelief. “Did-” Ochako started to say, “Did your Quirk evolve mine?!”

He laughed a little hysterically. “And then copy it!”

“WHAT THE FUCK?!” They both screamed.

And then Inko was hammering on his door. “Izuku! Ochako!” They heard her muffled voice.

The two quickly put on bathrobes and opened the door to apologize profusely to the harried woman.

“ALL MIGHT!” Izuku yelled as he and Ochako raced onto the beach where he agreed to meet his mentor the next morning, neither looking like they had gotten a wink of sleep.

“Where?!” Ochako gasped, looking around.

Toshinori, in his skinny form, coughed out some blood. What was his successor doing?!

“All Might! Quirk! Copy! Evolve!” Izuku couldn’t even speak.

“Dekun, who is this guy and why are you calling him All Might?” Ochako asked in total confusion.

“I-I’m not sure?” Toshinori tossed her a hesitant smile, “Did the young man hit his-”

“Shut it!” Izuku yelled, “All Might, my Quirk freaking evolved hers and then copied it! Look!” He held out his hand and a tube of light crashed on the beach for an instant and flattened it, before the sand, looking solid if crumbly, then rose up in a sheet.

All Might stared at the sight with his mouth moving soundlessly. Ochako still looked completely confused. After a moment, he pinched the bridge of his nose. “Okay, first of all, this is a bit earlier than I’d like, but…” He looked at Ochako, “I AM HERE!” He bulked up.

“ALL MIGHT?!” Ochako’s jaw dropped. “WHAT THE FUCK?!”

“I hope you’re having a good morning, young Uraraka!” All Might shot her his signature smile. She continued to gape, not saying a word. “Excellent!” He turned to Izuku, “And second of all, my young protégé…” All Might’s grin became a wee bit malicious. “CaN i bE a HeRo WItH a UsELeSs QuIrK?” He playfully ribbed his successor. Izuku’s face flamed red and he hid behind his hands. “AHAHAHA! Don’t worry, Midoriya-shōnen! I know just what to do here!” And with that, he vanished in a burst of speed.

“Izuku.” Ochako said after a moment, smiling pleasantly at her boyfriend. “Explain.”

Izuku knew true fear.

Two weeks later (and after some time apart, as Ochako went back to Mie as promised to celebrate with her family) Izuku, Inko, and Ochako were sitting down for what Izuku knew would be one of the most important broadcasts of their lives. “What’s this about, Dekun?” Ochako asked.

“We’re live!” The host, “And I have a very special guest here with me! Give it up, ladies and gentlemen, for ALL MIGHT!”

“Ahahaha, good to be here!” Toshinori blurred onto the stage in full costume before taking a seat on the sofa.

“Good to see our number one in the flesh!” The excited host belted out, “How long has it been since you first suited up?”

“Ahaha, you’re going to make me feel old with questions like that!” Toshinori smiled over at her, but the eagle-eyed among them saw something different in that smile. “Well, older, at any rate.” Silence. The entire audience had stopped clapping and now were looking at each other in confusion. “It’s been over thirty years since I first suited up. Closer to forty now, actually. I can’t believe it’s been that long.” The woman began to shake slightly as she realized what might be happening on her show. “And all those years ago, I set out with a goal in mind. I set out to create a society where a teenager didn’t have to leave his house with a metal bat just to go to school.”

The most intelligent in the room began to silently cry. Onlookers did as well as even through the TV, they could see just how tired the Symbol of Peace looked.

“I set out to create a society where even a bystander could offer a hand to a stranger without worrying that it was just a trap to steal the clothes off their back, or worse.” Toshinori continued, “I set out to create a world where evildoers had to think twice before committing their vile acts. And for a large part, I think I succeeded.” He smiled softly, “Even if I always think back and wonder if I could have done better. I’m not perfect and I never was, no matter how much I wished I could be. I made more than my fair share of mistakes.”

“All Might…” The talk show host forgot all her lines and prepared questions. “W-What are you saying?”

He chuckled lightly, “More than six years ago now, I fought a villain. It was a fight we kept out of the public’s eye.” He said softly. “The most memorable villain of my life. Years and years of fighting the worst of the worst made me forget just how bad the worst could truly be.” He put a hand on his side, “And unfortunately, even in victory, he left me a parting gift.” He began to steam, shocking the host and the audience. “One that has been slowly sapping my strength for some time. I’m not the same All Might I once was. So it’s time.” He said, and then he let go, revealing his skeletal self to the world.

Not a soul moved and not a sound was made as the exhausted, gnarled-looking man raised a finger and pointed it at the camera. “Next.” He smiled. It was an ugly thing. Not at all like the smiles he’d worn as the number one Hero. And yet people began to sob all the same. “Next…is your turn.” That simple sentence had said more than any number of explanations or analysts possibly could. 

Silent tears ran down Izuku’s cheeks as he clenched his fists in his lap. Next to him on either side, his mom and lover were sobbing as well.

“My successor is out there!” Toshinori declared as he let his hand drop. “One of you. You don’t know if they’re a man or woman… or perhaps even neither or both.” He chuckled slightly. “They’re not ready yet… but they’re out there. And one day, they will stand up tall and declare that they are here.” Toshinori sat back as he dropped his bombshell.

“Izuku…” Ochako whispered, gripping his hand tightly. He closed his eyes tightly, the tears continuing to fall.

It took several minutes for the crowd to stop crying and screaming their farewell to the greatest Hero to ever live. Toshinori let them have it as he rested, before holding up his hand. “I’ll leave you with one last announcement. Today might be my final day as a field Hero, but I do not intend to disappear or go quietly into that good night.” He grinned again, “To all the young men and women of the nation ready to try to fill my shoes… I’ll see you at U.A. as the teacher of Heroics 101.”

The crowd erupted into raucous cheers.

Izuku and Ochako walked hand-in-hand towards their destiny. With her Quirk having evolved and his own giving him quite the surprise, they were back in hardcore training mode. For the entirety of their break (other than Ochako going home here and there) the two had practiced from before sunrise to near sunset, taking breaks only to eat, sleep, and make love. Her evolved Quirk was both harder and easier to use and they needed the practice. Easier because she no longer had to touch something to use her Quirk anymore.

Harder because they had accidently turned a steel trash receptacle into a pancake.

And then shot it into orbit.

Yeah, they needed to be careful with their new powers over the fundamental force.

Their vacation time had passed frustratingly quickly, and soon enough it was time. They stared at the door of class 1-A and turned, smiling at one another. “Ready, Dekun?”

“Ready, Mochi.” Izuku winked at her, earning a small, pleased blush.

“Hopefully Bakucunt isn’t here.” Ochako said as she held a hand out for the door.

“Or that blue guy with the stick up his ass.” Izuku agreed as she opened it and they stepped inside.

And then both of them stopped and looked around. Izuku first felt incredulity and then a frustrating amount of hunger as he took in all eighteen other students and came to a fundamental realization about reality.

Every single other member of their class was a woman, and every single one of them was unreasonably attractive.

Ochako could almost feel her boyfriend’s lust aura intensify. She smirked slightly and licked her lips.

AND DONE!

Hope you guys enjoyed! Now, very obviously, this is a smut fic. That’s the whole fucking point. LOL Hope it was enjoyable at least!

But the focus won’t be on just smut but also fluff and some sprinkling of comedy. Hope I succeeded in all facets! I cracked up at more than one of the jokes. There will obviously be combat. It’s MHfuckingA. But it won’t be a hard focus. I’m sure everyone here can already picture in their minds’ eyes what will happen when Shigaraki decided to be a bitch. LOL

Yup, the entirety of 1-A consists of Izuku and (some of) his future ladies. All of canon 1-A and of 1-B is present, plus a few MHAified crossover ladies. You’ll find out his full class list next chapter if/when it gets written.
