You probably should have just said no.
Though it was so incredibly hard to deny Izuku of anything, it wasn’t impossible. Difficult beyond belief, but not impossible. You only had yourself to blame, really, when you agreed to his request. You even had a few days to back out, but a part of you just couldn’t get yourself to let him down.
But really, you wished you didn’t sign up to pretend to be Izuku’s partner when all you wanted was for it to be real.
“Are you ready?”
No, you weren’t, but you couldn’t exactly tell Izuku the truth as you stood outside his family home, second away from attempting to convince everyone that you were dating. The very thought made you flush.
“Wait, hold on,” You hesitated, grabbing his arm gently to stop him from opening the doorway. He followed your direction immediately, checking you once over to make sure you were alright. Just another reason why you were hopelessly in love with your friend—he was just so good. “Do you remember the backstory?”
“Yeah, do you? I wrote it all down if you need to review.” He nodded, and the fact that he had taken notes on your fake relationship made a grin form on your lips.
“No, I’m good. It’s just…” You trailed off, dropping your gaze from him in an effort to make the heat in your cheeks disappear. “Will your mom be suspicious if we aren’t physically affectionate? We never really talked about that.”
From the corner of your eye, you watched the color rise up Izuku’s neck and take over his features.
“I don’t think so? W-we could hold hands, but only if you want!” He hurried to ensure you were comfortable, just like he had from the moment his plan was brought up. He was just as nervous as you were, only you were doing a better job at hiding it.
Barely.
“Okay, yeah.” You agreed, sliding the hand that was holding his arm down until it wrapped around his own. You could feel the raised skin from his scars under the pads of your fingers. Subconsciously, you brushed your thumb over the worst of the damage on the back of his hand.
“S-sorry about my scars. I know they’re weird.” He apologized, not able to look at you. Frowning, you squeezed his hand once in silent reprimand. He had led you to the front door and was seconds away from letting you into his childhood home, but you couldn’t let him continue on thinking you thought his scars were weird.
“They’re not.” You murmured as he pushed the door open, sounds and smells of dinner cooking alongside lively conversation washed over the two of you and almost drowned out your words. “I don’t think so, at least.”
True to his nature, Izuku flushed at your words, but was kept from responding as none other than the Inko Midoriya raced towards the sound of the front door opening to sweep her son up into a massive hug. Izuku didn’t let go of your hand as he hugged his mother back, an action you both didn’t miss and felt incredibly endeared by.
“Mom,” Izuku started, gesturing towards you with his free hand when he finally let his mother go. “This is—”
“I know who this is.” Inko interrupted, pulling you into a hug just as tight as the one meant for your son. Instantly, you felt a wave of guilt for lying to this woman about the truth of your relationship with her son. Izuku hadn’t said anything about it, but you knew that you’d have to fake break up after the dinner. You couldn’t exactly fake date forever. “You’ve talked about them for weeks! I’m so glad to finally meet you, dear. I’ve been begging Izuku to bring you over.”
“Mom,”
“I’m glad I could make it,” Overtop Izuku’s whine, you managed to force the words out despite how flustered you were at discovering Izuku—apparently—talked about you to his mother. So much so, that she had been asking about meeting you.
You were so screwed.
“The food’s almost ready. Everyone is in the other room.” Inko started herding you and Izuku towards the sound of chattering. He kept his hand clasped around yours, even as his mother nudged him around, but you couldn’t help but realize that he was doing everything in his power to avoid looking directly at you.
Was he embarrassed? The whole point of the evening was to pretend that the two of you were dating to get his mother to give him some space on the matter, so why would he care that she believed your ruse?
“Go socialize, you two!” Inko gave you one final push into the sitting room, already dotted with Izuku’s various aunties and other relatives. You hadn’t expected to recognize anyone, which is why you were totally surprised when you met a set of very familiar red eyes.
“No shit. You actually went through with it.”
“Kacchan!” Izuku’s panicked voice filled the silence left by Bakugou’s crude and cryptic comment. All of the aunties in the room paused to glare at him, and Bakugou’s mother cuffed the back of his head in reprimand.
This was bad. Bakugou was the only one who knew about your crush on Izuku. It wasn’t that you had told him, but more so that he confronted you about your feelings one sparring session and you panicked too fast to deny it. Since he was the only one who knew, you had thought it was safe to mention your fake dating plan to him.
Now, you were certain you were going to regret it.
“What are you doing here?” You asked, though you knew that the Bakugous and Mrs. Midoriya had been friends since the boys were in preschool. You just didn’t know why he had to be there. If it had been a different situation, you would have laughed at the sight of Bakugou sitting on Mrs. Midoriya’s small couch with neighborhood aunties surrounding him on all sides. But he was grinning far too smugly for you to consider the possibility that he would keep your secret.
“I was invited,” Bakugou shrugged nonchalantly, then dropped his attention down to your hand wrapped around Izuku’s, and you just knew he was going to make some teasing comment. It was bad enough he taunted you in private over your crush on damn Deku, but you knew you were in serious trouble in front of a crowd. “What are you doing here?”
You grit your teeth at the smug asshole, face burning so incredibly bright red. From the corner of your eye, you knew Izuku was in a similar state.
“I’m Izuku’s date,” You explained what he already knew. It was hard enough to pretend to date Izuku to begin with, but now to do it all with Bakugou watching?
“Yeah, my date.” Izuku nodded. From the expression on his face, you knew he was thinking something similar to you. He was even closer to Bakugou than you were.
Bakugou smirked, but after a moment’s hesitation, he shrugged and went back to whatever conversation he had previously been in before your arrival. As he dropped the topic, you let out a breath you had been holding in due to nerves.
“That was close,” You murmured in Izuku’s ear as he led you across the room to an empty seat.
“Sorry,” He whispered back, close enough that you felt his breath brush against the shell of your ear. Shivering, you glanced at him out of the corner of your eye. “I kinda forgot that Kacchan would be here.”
“That’s alright,” You assured him, even though the way your heart was pounding in your chest was absolutely not alright. “I think he’s playing along for now.”
A truce, it would seem.
You should have known you couldn’t trust Bakugou when it came to matters of teasing Izuku.
At the dinner table, you sat beside Izuku, his hand still diligently holding yours. Of course, Bakugou had seated himself across from Izuku, shooting the two of you knowing, taunting looks as you ate. It was hard to answer Mrs. Midoriya’s questions about yourself or follow the conversations around the table when you were just waiting for Bakugou to start something.
“How long have you been together, again?” Inko asked politely as she served more of the food she had made onto your plate. You smiled graciously at her, trying to remember the story you and Izuku had created.
“A month.” You felt so guilty for lying, but Izuku had asked you for a favor and you’d agreed.
Though, it felt less and less like a fake date when Izuku refused to let go of your hand for a moment. Under the table, your fingers were threaded together and resting in your lap.
“Uh huh. And how’d you get together?” Bakugou cut in, shit-eating grin on his face as he leaned forward, interested in the conversation about your relationship.
“Katsuki, you’re being rude.” His mother chastised, but you felt a sudden need to rise to Bakugou’s challenge. If you were going to fake date Izuku, then you were going to do it right.
“Izuku just asked me when we were hanging out one day.” You countered with a newfound bravery. It wasn’t exactly a lie—you had been hanging out with Izuku when he asked you to be his date, only with the caveat that it was fake. Bakugou grinned at you playing into his game, leaning forward on his elbows.
“Yeah, Kacchan, you know.” Izuku stammered to back you up, and you smiled softly at him, brushing your thumb over his scarred knuckles once more under the table.
“What did he say, exactly?” Bakugou pushed for details, smirking.
“Why do you want to know?” Your face scrunched in confusion. It seemed more like he genuinely wanted to know instead of just teasing the two of you.
“Curious,” Bakugou shrugged, though his attention suddenly was fixed on Izuku, who was flushed bright red. “What’d ya say, Deku? Anything dramatic when ya asked ‘em out?”
You turned to face Izuku with a confused frown. It seemed like Bakugou was having a separate conversation with Izuku right in front of you.
“Oh, leave them alone, Katsuki!” Mrs. Bakugou ordered, and you realized exactly who he got his temper from. Scowling, Bakugou turned his focus from you and Izuku to argue with his mother. Despite your confusion, you managed to steal a glimpse at Izuku and found him blushing red and pushing food around his plate as if he was deep in thought.
Your secret was safe, for now.
Somehow, you made it through dinner without further comments from Bakugou, and before you knew it, Izuku was walking you home.
“I think it went well.” You hummed, breaking the tense silence that had fallen over the two of you the moment his front door shut. His hand had slipped from yours once the night was over, and with it went any disbelief about what the night had been about. “I’m sorry that I probably won’t get to see your mother again.”
You really were upset about it. Inko had been an absolute delight, and you knew exactly where Izuku had gotten all his sweetness from. But at the mention of your inevitable fake breakup, Izuku tensed from beside you, pausing on the sidewalk outside his building.
“About that…” Izuku muttered, trailing off in nerves. You frowned at him in curiosity, having to fight the newly developed urge to hold his hand. How were you supposed to go back to normal after a night of pretending everything you wanted was real? “I, uh, actually meant for this to be real.”
“What?” Your mind went blank as you tried to process what he said. It wasn’t out of character for him to suddenly drop information on you out of nowhere, but never had it been something so serious as his possible feelings for you.
“When I asked you to be my date tonight.” He clarified, voice wavering. “I meant for real.”
You blinked slowly at him, barely able to keep your jaw from dropping in shock. How hadn’t you realized? When he asked you, you had just assumed he meant fake dating, and he had never corrected you. But to know that he meant it as a real, actual date? You couldn’t believe it.
“Why did you let me think you meant to pretend?” Shock was the only emotion evident on your face as you watched Izuku’s face flush at your admonishment.
“Because I didn’t want to push my luck! Plus I thought it might have been your way of letting me down easy. But Kacchan kept teasing, and I thought maybe he knew something I didn’t. And I don’t know, I’m really nervous right now. Please say something. Anything, really—”
“Izuku Midoriya.” You interrupted his rambling with a call of his full name, and it works a little too well, getting him to stop talking at the cost of making him go pale and freeze with wide eyes.
“Oh no.”
“You’re adorable.” Recovering from your shock, you grinned, reaching out to wrap your hand around his like you wanted to from the start. Holding his between both of your own, you made sure to brush your thumbs over his scars he had said thought made him weird earlier in the evening.
“Oh?”
“Ask me again.” You encouraged him, a smile gracing your lips as you watched every expression that washed over his features.
“What?” Ever oblivious to matters of the heart, his face twisted in confusion. “But the dinner is over already.”
“Izuku.” You tugged on his hand, bringing him half a step closer to you. “Ask me again.”
It seemed to dawn on him what you meant, and a blush bloomed across his face while he gathered his courage.
“Will you be my date to my mom’s holiday dinner party?”
“Of course I will.” You giggled, knowing it was a little ridiculous that you were making him ask you again but unable to go without setting things right. You had been too oblivious to know what he meant before, but now you could fix it.
“Really?” He asked, eyes wide, as if you weren’t holding his hand between your own.
“If you want me to.” You shrugged, feigning nonchalance.
“Yeah.” Izuku nodded quickly, clearly excited. “Yeah, I really do. For real, this time.”
You laughed, rolling your eyes playfully at his teasing jab. You were probably never going to be able to live down your misunderstanding.
You tugged his hand once more until he was so close you had to tilt your chin up to face him. With your sudden proximity, his teasing tone vanished, replaced by one of thinly veiled nervousness. A sweetheart.
“Do you kiss on the first date?” You asked, voice innocent despite the question. Izuku’s face went red, and you could have sworn you heard him audibly swallow.
“I’m trying very hard to be cool about this, but I can’t lie to you. I’ve never been on a first date.”
Oh, now that you knew he wanted you, you were going to eat him alive.
“Do you want to kiss on the first date?” Rephrasing your question, you tilted your head slightly to the side to watch his reaction.
“Yeah.”
Gently, you set a hand on his cheek to guide his face closer to yours, taking the lead to press your lips against his in a short, sweet kiss. His lips were slightly chapped from the cold and how often he chewed on them, but you enjoyed the way he burned against you all the same.
“Did the nerd finally ask you for real?”
At the sound of Bakugou’s voice, you jerked away from Izuku. With the adrenaline of Izuku’s confession, and then your kiss, you had forgotten you were only standing outside the building he lived in. It was a miracle that only Bakugou had caught you.
“Kacchan! I didn’t see you there!” Izuku, as red as ever, greeted your mutual friend with a renewed energy he hadn’t possessed when he’d been taunted with your fake date. Now that you had cleared the air about your intentions, his confidence had come back.
And apparently ruined all of Bakugou’s fun.
“I was just leaving.” The blond rolled his eyes, shoving past the two of you with a frown and his hands shoved deep in his pockets. Watching him disappear down the sidewalk, you narrowed your eyes suspiciously at him.
“Did he know this whole time?” You asked Izuku. You knew you had confided in Bakugou about how you felt, and if Izuku had done the same, then he had known the entire time and could have cleared the air.
“I… think so.”
“Oh, I’m going to kill him.”
if it’s not painfully obvious, this isn’t proofread
also i feel like i could have done so much better
Bakugo is perfect for cuddling. Why? Cause he’s big and he’s warm.
I don’t mean just big cause he’s tall, I mean muscle, he’s a pro-hero after all, he’s gotta stay fit. So it wasn’t unusual for you to see his biceps practically ripping every atom of his compression shirt when he’d go out to the gym.
Despite coming back all sweaty the first thing he likes to do is lay on you and now convince you his germs have passed onto you so he has an excuse to shower with you. From there you guys find your way to your shared bed and cuddle. His muscles caging you in, his large calloused hands wrapped around your figure, and he couldn’t be happier. He keeps you warm too, thanks to his quirk his body is always warm/hot. (Thanks to this he also usually walks around shirtless.)
So it’s not uncommon for him to place his hands under your shirt, resting them gently along your sides as he uses just the right amount of heat to warm up his hands a bit. Usually he does it when you have cramps, he’ll have you lay your back to his chest and keep his hands on your lower abdomen while you rest. Such a good boyfriend.
“Cmere”
There’s no point in him saying that when he’s already got you thrown over his shoulder, taking you off the couch as if you weren’t peacefully reading.
“Kats-“ you can’t help but giggle, seeing he’s in one of his lovesick moods.
He gently places you on the bed before climbing on top of you, his head resting on your chest gently as you find your hand in his.
You smile seeing him find relaxation in your touch.
“I love you katsuki.”
His hand warms up a bit and you can see his ears turn a little pink.
—
“I love you too.”
pretty sure shigaraki tomura would be absolutely fucking floored by how much you being kind turns him on
like he’s watching you talk to spinner about video games, and you’re bouncing in your seat with excitement, and he doesn’t understand this strange buzzing in his chest.
when you let toga have some of your blood, no questions asked, or talk with twice when he’s lonely, the warm buzzing just gets stronger and stronger until he’s hiding himself in his room, jerking down his pants and pulling his cock out, barely holding back the whimper locked in his throat
it’d feel so much better if it were your hands. what would you do if you knew he was in here stroking himself like this, dick jumping in his palm, pre-cum beading at the tip?
he groans. would you offer to help? his breath catches as he thinks about you on your knees, those kind eyes locked on him. would you want to taste him? he’d want to taste you. he’d want your pretty pussy dangling right over his face. fuck, he knows you'd smell so fucking good -
you bang on the door. “tomu, what do you want for dinner?”
yeah, you’re going to be a problem for him

Plap plap plap -
"Oh god, Kats..."
It should be fucking illegal for walls to be this thin, Kirishima thinks, staring up at his ceiling, willing his dick to soften. This is the fifth night in a row that he’s heard your guts getting rearranged by his best friend, and it’s starting to take a toll on the pro hero.
“Yeah, baby? Too much for ya?”
A soft groan emits from Kirishima’s throat at the high-pitched whine you make in response.
It’s not gentlemanly of him at all, but he pictures how gorgeous your face must look right now, mouth hanging open, eyes rolled up in your head—
"Not enough," he hears you shoot back.
He slams the pillow over his face and rolls onto his belly, rutting his dick across the mattress in one long drag.
Fuck.
When he first heard you two have sex, he really tried to do the respectable thing and not listen, he swears. When noise-canceling headphones didn't cut it, he went on long walks the minute you and Bakugou disappeared behind closed doors. It’s made for some very awkward late-night convenience store runs.
He lifts the pillow from his face. No noises sound from next door. He sighs. Time to address the raging cockstand in his pants, then.
The fantasy he conjures is familiar, well-worn. He starts in the middle this time, at the part where you’re already gagging on his dick, eyes welling with tears as be bullies his cock down your throat.
Kirishima grabs the lube from his nightstand and coats his palm. His hips buck into his hand as he works himself up and down, idly wondering how much of him you'd be able to take. He hates it, but the thought of your face scrunching up as you struggle to fit him all the way in shreds his sanity to ribbons.
"Kiri?" your voice sounds through the door while his hand is mid-stroke on his cock.
It’s like he summoned you.
"Yeah?" Even that minor syllable sounds like he’s fucking drugged.
"Can I come in please?"
His eyes bug out of his head. Are you fucking serious?
"Just a minute!" he shouts, shucking up his sweatpants and toweling off the mess between his thighs.
He hears Bakugou’s voice next. "Just let us in, idiot, she’s gotta ask you something."
Shit.
Shit shit shit shit—
He’s gonna die tonight. You’re probably outside thinking he’s a digusting pervert, in here fucking jerking off to you—what was he thinking?
Apparently not even the panic can make his dick cooperate though. He tucks it into the waistband of his pants and prays for a swift end.
When he opens the door, he expects to dodge a punch. But you’re standing there in a see-through red teddy, and all semblance of thought goes out the window.
“Did you finally hear me this time, Kiri?”
Huh?
He’s pretty sure he just splutters. Bakugou barks out a laugh behind you. "Told you this dummy was in denial, pretty girl."
His brain stumbles. "You wanted me to hear?"
You let out a husky giggle that goes straight to his groin. If possible, he gets harder.
"I like how you watch me, Kiri," you admit, eyes darting to his lips. His mouth goes dry. "I keep thinking about how you’d touch me."
He balls his hands into fists at his side to keep from hauling you onto his bed. "This is something you two have talked about?"
Bakugou has the audacity to look annoyed. "Doesn’t take a fuckin’ genius to figure it out. You’re always starin’ at her. Besides," he runs a hand straight down your back; you shiver and lean back into him. "Can’t deny this sweet thing much."
The good thing about being a pro hero is that you learn to adapt to situations quickly. Kirishima's brain is spinning with this new information, but he’s reacting before he realizes it, hand reaching out for your waist.
Your nipples tighten—he wants his tongue on them, sucking through the lace. He looks to Bakugou, but the man’s just sauntering into the room, settling into the desk chair with his legs kicked out, gray sweatpants tented.
“Go on, then.” He palms his cock. “Make her feel good like you’ve been wanting.”
Kirishima doesn’t need to be told twice. He picks you up and arranges you both on the bed, your thighs draped over his hips. You’re soaking wet; he can feel the slick dripping from your pussy fall on his stomach.
He’s so hard it hurts.
You’re not much better off, whimpering and rutting in his lap like a bitch in heat.
"Touch me, Kiri, please," you say, nosing at his neck and sucking on his pulse point. "Need your big hands on me."
God, you even beg cute.
His hands span up your back, pressing your tits into his chest and capturing your lips in a searing kiss. You groan into his mouth, hands tangling in his hair, tugging at the strands.
"Wild little thing, aren’t you, baby?" Kirishima chuckles when you glare at him. "No judgment here, I fucking love it. Been listenin' to you long enough to have an idea of how you like it."
He looks over at Bakugou. "You just gonna watch?"
"Gotta make sure you do it right, Shitty-hair," he grits out, fist moving up and down. “Ya already need me to step in?”
Kirishima laughs under his breath. "Fuck you too, asshole." He cradles your face in one hand, tilting your lips up to his. "Come here, princess, let me see how hard I can make you cum, huh? Harder than he does?"
One breath against your clit and you’d probably scream for him right now. He can't help but puff out his chest a little at the thought.
Clothing comes off in a flurry. Every inch of skin exposed is a fucking godsend, more for him to touch, to caress.
When his cock bobs in between your bodies, he swears your mouth goes slack.
"Oh, Kiri," you breathe out, wrapping your hands around him. "You didn’t tell me you had such a pretty dick.” He chokes and rolls his hips into your fist. "You’re big, too. I don’t know if you’ll fit all the way."
He grunts. "Fuck baby, you can’t say shit like that to me, drives me fuckin’ crazy—"
The smile you give him is sinful. "I know." You shut him up by undulating your hips, sliding your pussy folds along the head of his cock.
"She's a little brat, Kiri, don't be afraid to put her in her place," Kirishima hears Bakugou say in the background. His voice is strained, husky. Both of you moan at the sound.
"Is that right, princess?" He nips at your mouth. "You think I'll give you whatever you want?"
You nod, the sweetest whine falling from your lips as he starts to inch his dick inside your quivering hole. You're so tight it's like your pussy can't decide if it wants to suck him in or spit it out.
"Stay fucking still," he growls, hold fast and hard on your hips. You squeal at his tone, gasping as he stretches you open, working the tip in and out.
Your hands scrabble at the sheets, his forearms, anything. He just holds you in place as your cunt gets sloppier and sloppier, lewd squelching noises filling the room.
"Kiri please just fuck me. Please, I've been thinking about it for weeks now—"
Bakugou kneels on the side of the mattress.
"You're mouthy tonight, baby. All because you're showing off for him?" He taps the side of your mouth. "Let's put that mouth to better use, yeah?"
If Kirishima wasn't about to bust his load, he sure as fuck is now, watching you greedily suck his best friend's dick as he works his into your sopping wet core.
When he finally bottoms out, the sound you make is pornographic, throat stuffed up with dick, humming out your pleasure...
"God that's so fucking hot, baby, look at you." He sets a rough, steady pace. Your tits bounce as your throat works to take Bakugou. Drool trickles down your chin; he wipes it away and squeezes your neck. It's driving him crazy, watching your tongue and lips work in tandem. "Takin' dick so well, there's a good girl."
Bakugou has a tight grip on the headboard, veins straining in his neck.
"Fuckin' hell, I'm close. Pinch her clit, Eiji, that'll make her cum quick. Get her there for me, let me see her fuckin' scream."
Kirishima rolls your bud between his fingers, and sure enough, your pussy starts clamping down on him. His rhythm gets erractic, wild. All he can think about is the sticky wet rush of slick between your legs, your channel milking his cock like you'd been waiting for weeks for it—
Bakugou slides out of your mouth with an obscene pop, spitting into his palm. "Dirty little slut, love getting used, don't ya?"
Kirishima keeps working your clit, dick jumping inside you. "There's our pretty girl, doing so well. Where do you want me to cum, honey? Can I cum here?"
He presses down on your tummy and pinches your clit at the same time. Slick gushes out of you.
"Cum in her, Kiri," he hears Bakugou bark out, hand speeding up. "I'll clean it up later, just wanna see you both cum with your dick in her."
It's embarassing, but that's really all he needs to hear before he's coming the hardest he ever has, cock twitching and pumping seed into you as Bakugou spends onto your tits.
Your own orgasm takes you over, bowing your back off the bed, mouth hanging open as incoherent babble falls from your lips. Kirishima fucks you through it, each small tremor of your subsequent orgasms like jolts of lightning.
He's pretty sure he knows the answer when he asks, "We get to do that again, right?"
You look at Bakugou, who just smirks. "Won't get rid of us that easily."

BY THE BOOK : MIDORIYA IZUKU X READER
SUMMARY: When your pro hero boyfriend comes home to find you studying, he suddenly takes a great interest in helping out. You find his methods... questionable. TAGS/WARNINGS: nsft, hysterical literature (reading out loud while sexually stimulated), pro hero deku, deku still has ofa, support tech grad student reader, slight intelligence kink, gn + afab reader, cunnilingus, established relationship, aged up characters, fluff (3k) NOTES: Hi guys! I have been in survival mode as of late and the writing has been slow going; my sincerest apologies for how long it’s taking me to burn down my @ficsforgaza backlog. But I finally had the time & energy on my hands this weekend to work on this one and I had such a blast!! I hope I’m not too rusty–and if I am, I hope you enjoy it as much as I loved writing it regardless lol. Love you and thank you always for your patience. Happy Holidays!!
Sometimes, you thought you could tell your boyfriend was near, even before you heard his key in the lock.
It was something to do with his power, you’d always suspected—as a support engineer unduly interested in other people’s capabilities, you’d spent hundreds of hours turning it over in your head. It was the unnatural immensity of other people’s powers, you thought, pulling and coiling just beneath the surface of Izuku’s skin. In close proximity, after prolonged use, its presence felt like a shiver up the back of your neck.
You felt the barest hint of it now, an unsettled feeling creeping into the marrow of your bones, and you sat up on the couch just as you heard the scratch of Izuku’s keys at the door.
One For All fit cleanly into Izuku’s own unwavering intensity somehow, like the last piece of his puzzle. Though one would certainly never think so looking at him as he spilled through the door, pink-cheeked from the cold, all bright eyes, sweetly angelic features, and a riot of wild green curls. He looked windswept from the biting winter breeze. He also looked too kind to be carrying the sort of power he did—too sweet and eager and lovely.
“Look what the wind blew in,” you grinned at him over the back of the couch, after assessing he was well. Your eyes tracked the sinuous movement of those broad shoulders as he yanked his mouthguard over his head, the flex and pull of his bicep as he hung it beside the door. He was moving without pause, no sign of injury or muscle strain , and his suit was intact. Ordinarily you didn’t mind if there was a bit of shredding about the abs as long as he came back to you whole and hale, but in the winter you didn’t like him wandering about risking the chance of frostbite.
Your heart fluttered when Izuku returned your smile with one of his own, so beautiful and bright, chasing away the cold he’d tracked in like a warm sliver of sun.
“Lots of small, easy fights today?” You guessed, judging from his intact suit but clear whiff of power about him.
Izuku scrubbed a hand through that riot of curls, exposing the reddened shell of a cold ear. “I only had to use blackwhip a couple of times,” he said as he shouldered the door closed behind him, the muscle of his thighs flexing enticingly as he stepped out of his boots.
You gestured at the pot of soup you’d left warming on the stove, and the veritable pile of crusty bread beside it. Warmth and carbs, exactly what you would have wanted if you were a pro hero fresh off a long day of patrolling in the snow.
Izuku’s eyes fixed on it with an obliging amount of interest, and he almost tripped over himself in the genkan in his haste to get to the kitchen. “I love you,” you heard him say, muffled through a mouthful of bread, heard the clatter of the silverware drawer and a bowl being placed on the counter.
You smiled and turned back to the book in your lap, a particularly dry, knotty text on robotic imitation learning that had had your eyes drifting closed for the better part of an hour. It was the last you’d need to get through for your Wearable Technologies graduate course, and something you were deeply interested in incorporating into your design practice. You could train a piece of equipment on how an individual pro hero moved and deployed their quirk, and use predictive modeling to deploy assistance functionalities within milliseconds if you got it right—such as immediate cooling in pro hero Shouto’s temperature vest the moment he ignited an arm.
The implementation was going to be so cool—but the theory was so mind numbing.
You felt the couch sink in beside your feet, and Izuku peered interestedly at the title in your lap.
“Introduction to Robotic Imitation Learning,” he echoed, and you could hear the note of excitement in his voice. You suppressed a fond smile, knowing he was already thinking through the same applications you had—he was just as much of a nerd as you were.
“Introduction to Snoozing and Napping,” you grumbled, turning back to your page. “There are only so many words on the Kalman filter framework a brain can handle before the human mind shuts itself down.”
Izuku hummed in interest around a spoonful of soup, propping himself up against your leg. The exterior of his suit was still cool from the outside, and he groaned with relief from the warmth of your skin, even as you hissed at the chill.
You knew he wanted you to go on, so you generalized for him. “It’s an algorithm used for robotic motion planning—you not only take measurements of the thing you want to model but you account for uncertainties to predict the probability that something is going to happen.”
Izuku nodded, taking another spoonful of soup, gesturing for you to go on.
You summoned up the willpower to explain joint probability distribution, pleased when Izuku easily managed to follow—he’d always been a quick study, especially of anything that could be employed in the service of heroics. You’d long thought if he hadn’t been gifted his quirk, he would be an insane support engineer.
He managed to finish his entire bowl of soup in the time it took you to explain, and housed another two slices of buttered bread with the sort of alacrity you’d only ever seen in pro heroes and professional athletes, making you smile while you spoke.
His spoon clinked softly against the edge of the bowl as he set them aside on the coffee table, and he hooked his chin over your knees as you finished explaining. In the setting sun from your windows he looked especially lovely, the kind, angular planes of his face brushed in gold, softening the spots of his freckles.
His eyes were especially bright, the way they always were when something in particular had caught his interest, and he smiled at you again over the tops of your knee caps.
“I admire how smart you are,” he told you, in the simple, straightforward way he always gave out compliments. It was like a shot to the heart every time, and you could feel your face warm with the praise even after years of receiving similar compliments.
You reflexively flapped a dismissive hand. “Not smart enough to have internalized it all! I have mostly been falling asleep to it,” you promised him.
He tilted his head, a green curl falling into his eyes. “I know you won’t have a problem when you’re awake.”
You shifted your legs with embarrassment, and a long fingered hand came up to cup the front of your thigh, as Izuku turned more fully towards you. You could feel the warm, hard planes of his chest against your shins, the line of his jumpsuit’s zipper pressing insistently just below your knee.
“Gotta try to impress you somehow,” you joked, your skin prickling as Izuku’s fingers absent-mindedly drew a pattern across your thigh. You could feel the heat of his hand through the thin material of the leggings you’d lounged around in all day, the chill finally chased away from his skin now that he’d come inside and warmed up.
“You do impress me,” he said in his soft, gentle tone. Which made your cheeks and nose burn hotter.
You knew you did, and the steady faith Izuku had in the people around him was one of your favorite things about him. It still made you feel like a middle schooler with a crush to think about, though, the intensity of your feelings too much for one body to handle.
“I will study hard to live up to your faith in me,” you promised, unable to help the goofy smile you knew you were giving him.
Izuku’s chin shifted against the tops of your knees, and he pressed his mouth to the knob of your left one, leaving a smiling kiss. “Tell me more?” he asked, fingers still sliding softly over your thigh.
“I’ll read it to you as I go, then,” you said, turning back to the brick of a tome, propping it up more firmly on your stomach as you adjusted yourself against the couch arm. Izuku’s eyes watched you over the top of the pages, that emerald gaze tracking your face closely.
“‘The algorithm works via a two-phase process: a prediction phase and an update phase’,” you began, trying to turn your attention away from Izuku and back to the text. “‘In the prediction phase, the Kalman filter produces estimates of the current state variables, including their uncertainties. Once the outcome of the next measurement (necessarily corrupted with some error, including random noise) is observed, these estimates are updated using a weighted average, with more weight given to estimates with greater certainty.’”
Izuku’s long fingers traced firmer lines across your thighs, almost like he was taking notes. He layered another kiss along the line of your knee, eyes glittering at you as you read.
“‘The algorithm is recursive,’” you continued, “‘It can operate in real time, using only the present input measurements and the state calculated previously and its uncertainty matrix; no additional past information is required.’”
You almost jumped as Izuku’s mouth trailed lower, into the space between your knees, leaving kisses along your inner thigh. His fingers gently pulled one thigh away to make space for him in between, and you cleared your throat, trying to return to the text at hand.
“‘Optimality of Kalman filtering assumes that errors have a normal–that is, Gaussian–distribution,’” you read on. “‘The following assumptions are made about random processes: Physical random phenomena may be thought of as due to primary random sources exciting dynamic systems. The primary sources are assumed to be independent gaussian random processes with zero mean; the dynamic systems will be linear.’”
Izuku let out a soft breath, insinuating himself further between your thighs. Your own breath came out a little uneven as he bent over you, mouth tracking dangerously towards the inseam of your leggings.
You paused, but Izuku fixed you with a look of his slightly-darkened eyes. “Please—keep reading,” he said, his tone a little lower than it had been a minute ago.
You swallowed in shocked understanding, skin tingling. You felt yourself nod, as Izuku’s fingers strayed to the waist of your pants, dipping below the band.
You let him slowly peel your leggings down, your underwear with them, adjusting as needed to make it easy for him, even as you tried to return your attention to your textbook.
“‘Regardless of Gaussianity, however, if the process and measurement covariances are known, then the Kalman filter is the best possible linear estimator in the minimum mean-square-error sense,’” you quoted, nearly squeaking when Izuku pressed his mouth to your hip, his curls tickling the skin of your belly. His hands gripped either side of your thighs, palms square and rough against your skin, and you tried not to shiver with the feeling.
“Um—‘Although there may be better nonlinear estimators’,” you said, then nearly jumped out of your skin when Izuku pressed his mouth to the core of you, only the strength of his grip stopping you from accidentally kicking him in surprise.
“Oh my g—uh! It—um—‘It is a common misconception perpetuated in the literature that the Kalman filter cannot be rigorously applied unless all noise processes are assumed to be Gaussian,’” you managed, before your cut off into a groan as Izuku layered a hot, sweet kiss over you, tongue dipping carefully between your folds. “Ah-–Izuku—”
Izuku petted a thumb gently over the top of your thigh to show he was listening, even as he swiped his tongue over you again, a long, firm stroke that had your thighs flexing in his hold. He laved over your clit, sucking ever so slightly, and your grip almost tore the edge of your textbooks as it tightened.
“Keep going,” he urged briefly, then did it again, punching a groan out of you.
“Extensions—oh—‘Extensions and generalizations of the method have also been developed, such as the extended Kalman filter and the unscented Kalman filter which work on nonlinear systems,’” you read on, voice shooting up nearly into a squeal when two of Izuku’s long, firm fingers pressed into you, as his mouth moved over you again.
“Ah! Oh my god—the—um, the basis—-” you said, breath growing short. Izuku’s fingers unerringly found the spot inside you that made you twist in his grip with the ease of long practice, and his jaw worked as he kissed you so shockingly filthily. You could feel something already starting to build up behind your navel, a fluttery lightness, an insatiable insistence on more.
“‘The basis a hidden Markov model—oh, fuck—such that the state space of the latent variables is continuous and all latent and observed variables have–ah!--Gaussian distributions,’’’ you recited, your voice tripping up further into a register that sounded more like begging than reading.
Izuku’s fingers worked you, long and thick and perfect inside you, as his tongue drew unrelenting circles around your clit. Stars seemed to spark in your vision, and your eyes squeezed shut, losing your place on the page as your hips flexed into his face. You felt suddenly very floaty and lightheaded, and not at all in a position to keep going.
Still, you tried to refocus your attention.
“‘K–Kalman filtering has been used successfully in—oh—multi-sensor fusion—ah, ah!--and distributed sensor networks–fuck, please, Izuku—to develop distributed or consensus Kalman f-filtering,’” you said, your tone nearly a cry.
Izuku groaned softly, sucking gently as his fingers curled inside you. It made your veins spark under your skin, your legs shaking in Izuku’s hands. You abandoned your grip on your book to seize the arm of the couch, clawing desperately at the fabric.
“Please, Izuku,” you cried, hips bucking towards his mouth.
The book tumbled off your stomach but you hardly noticed, gaze refocusing on the way his eyelashes fluttered as he licked you. His fingers played gently within you, a maddening press that was simultaneously too much and not enough, and his other hand came up to slide under your sweater, plucking gently at your nipple.
You lost yourself to the feeling—caught between the mind-melting curl of his fingers, the delicate suction of his mouth, and the careful pinch of your nipple. A delicious heat curled through you, waves of unbearable pleasure, and you could hear yourself babbling nonsense—garbled syllables of Izuku’s name, and every entreaty you could think of, a hundred thousands mores and oh pleases.
Izuku abandoned your nipple to pull you more firmly against him with a strong arm curled under your thigh, pressing you even harder into his mouth.
You muffled a scream in the sleeve of your sweater as he sucked you harder, tongue laving over you in loving strokes. Only his terrible strength held you down as you writhed beneath him, and then his fingers twisted in a way that had your vision whiting out—and you were suddenly thrown out over the edge of your pleasure.
Izuku licked you through it as you squirmed and begged and cried out his name, your climax seeming to last for eons.
You were panting hard when you finally slumped into the cushions of your couch, the ceiling seeming to swim in and out of focus before your eyes. When you gained enough control of your body again you looked down at Izuku, finding him watching you with a satisfied, almost shy curl to his mouth.
“You’re beautiful,” he told you, emerald gaze glittering with sincerity. “You’re so smart.”
Impossibly you felt your heart swell with even more love for him, and you seized his shoulder, dragging him up over you so you could kiss his mouth. The taste of yourself on him was embarrassing yet thrilling, and you petted a pleased hand through Izuku’s wild mess of curls as you kissed him.
“Well you are amazing,” you told him, swiping a thumb over his cheek fondly, smoothing over his freckles. A gorgeous watercolor of pink washed over his cheeks and nose at the proclamation, and you could hear his fingers flex in the cushion beside your head.
The sight of him flushed and waiting over you like another small something inside of you, like a pilot light, and you let your mouth pull into a wry grin.
“I hope you know I learned nothing though,” you said casually, your plan for your next steps already forming in your head. You let a hand trail carefully down Izuku’s flank, tracking towards his waist. “I think maybe I might need a few rounds for it to really sink in.”
Izuku’s ears went red against the green of his hair, and you felt your smile widen. “Maybe you could read it to me this time?” you asked, guiding him to roll under you, retrieving your book from the floor as you did so.
You settled yourself on the tops of Izuku’s thighs, feeling the hard press of him against your core, as you placed your textbook into his waiting hands.
Izuku’s answering smile was all the permission you needed. You directed him to start from the beginning of the chapter, and he did so in that soft, lilting tone of his you so loved. And then your fingers trailed up to the zipper at his collar.
It was time to return the favor—wholeheartedly.
