"How Do You Read So Many Books??" I Am Simply Trying To Avoid Reality, What Are You Doing

all i think about is sex and how i’m going to die

my kink is more subversive and avant-garde than yours. your kink could be easily understood with a few googlé searches but mine requires lengthy knowledge of classical and modern literature. and it’s more taboo as well.

never been normal about anything

Based off a twt reference trend 💥🧨

i get so annoyed when people extend a word incorrectly. what do you mean you had a "hugeeeee" burger. dont you mean a huuuuge burger? are you saying "huge-eeeeeeeee" out loud huh??? you start buzzing like a damn mosquito? well i fucking kill those. so watch out

oh my GAWD. obsessed with this.

let me ☆ ( ​prohero!katsuki x fem!prohero!reader ) — you underestimate how gentle katsuki can be, if you needed it | smut

( warnings. ) minors and ageless blogs dni ! fingering, praise, soft gentle sex iktr, reader is going thru tough times & katsuki takes care of you, timeskip!katsuki — 18+

You underestimate just how gentle Katsuki can be.

The instant your fingers click on the lock, Katsuki is already a step behind, his presence a looming force over you like an unshaken shadow. There must be something on your face; Katsuki frowns as he studies it intently, fingers ghosting over your arms, like he’s trying to read between lines that you haven’t even drawn in yet.

"Something happened." He doesn't phrase it as a question, sounding sure of himself. “What?”

"I'm safe," you swear to him, pulling your coat off. "No bruises or anything. See?"

He ignores your extended arms, pinning your gaze with his own. "What," Katsuki demands.

"Katsuki—” You sigh and attempt to push past him. He just rears back and keeps his eyes trained on your face searchingly. "Katsuki, I'm too tired to deal with this."

His brows dip downward further. "I can't help you if you don't tell me."

You falter, struggling to maintain this flimsy display of strength — he knows you too well for that.

He waits. Patient, gentle, like he’s so sure that he can carry this burden with you. You know he can. It’s that fact that makes you think, Of course not. Of course you could never be too tired of him. He never tires of me, too.

“I don't—” you say, looking away, “I don’t know if I can keep doing this anymore. Am I even doing anything right?”

There must be some other reason — Katsuki is evidently fumbling at the threads to tie it all together in his head, but as of the moment, that is all you’re feeling. You don’t know if you can keep doing this. Your limbs want to sag to the ground, knowing it has to prepare again to face the brunt of tomorrow — but you have to care for it, too, or else you’ll wake up dead. Katsuki doesn't deserve that, even if you’re falling apart.

"Everything is just so hard," you continue, the surge of emotions you'd been desperately keeping a tight leash on bursting at the seams; "None of it makes any sense. I don't know if I'm doing anything right."

Katsuki's frown eases. "C'mere."

The next breath you take comes out wet and shaky. The next step you take gravitates to him.

Katsuki pulls you to his chest as you sob. He buries his nose into your hair, rubbing shapes into the small of your back. It almost feels like he’s coaxing it out of you with every touch. You cry violently, lungs spasming, everything pouring out finally — and throughout it all, Katsuki doesn’t split away, even as your tears and snot leave a disgusting patch on his shoulder. If anything, he keeps you enveloped in his warmth, as if he can tell that it helps even without being told.

“N-nothing happened,” you sniffle, trembling, and Katsuki pushes off just enough to see your face; “But it was so overwhelming. I just — I dunno.”

“Baby,” Katsuki starts. You’ve never heard him speak so softly before, low and rough and embodying gentleness that you don't know if you deserve. “Let me take care of you tonight, yeah?”

That sounds good. God, you want him to do that so bad. But looking so weak in front of someone so remarkably strong like Katsuki is embarrassing. You're not some child needing to be told that you're doing good and everything will be all right — needing to be coddled because you had a bad day.

“I want to,” Katsuki says; you feel as though he can read your mind. "Let me."

"…okay." You nod, averting your gaze. "Please take care of me."

And so Katsuki helps you bathe, kisses your knuckles, pulls one of his shirts down that reaches to your mid-thigh, brushes your hair out of your eyes, feeds you dinner he's cooked, and kisses you again. All the while, it's silent. Peaceful. It should unnerve you that Katsuki hasn't spoken a single word since, but you revel in the comfort of hearing his measured breaths instead.

It’s like you can hear him think: You’ll be okay. So let me take care of you. Let me help you be okay.

You feel like you're melting out of your own body, sinking into the comforter's embrace on your shared bed, losing tension in Katsuki's scent and affection.

“Pretty,” Katsuki mumbles, his hand crawling down.

Then you go still when Katsuki watches your expression as he glides a finger in between your legs.

Your cheeks burn. "I — w-what—"

Katsuki hums, thoughtful. "You're already…"

Well, it happens that today is a day of many discoveries. It turns out, Katsuki's hands can be so soft as he works shampoo through your head, and you get horny seeing how attuned your boyfriend is to your needs.

Katsuki can be so gentle with his hands. Of course you’d been thinking of how gentle he can be elsewhere.

"You want me to?" Katsuki asks, slipping a hand under your shirt. His heated fingers caress your waist, his thumb rubbing circles that trickle hotness down elsewhere.

You aren't sure why you feel so shy. You've done worse with each other. "You don't have to. If you just feel like you have to—"

Katsuki lifts an impatient brow. "You think I wouldn't want to?"

You squirm, suddenly aware of the empty ache that is longing for Katsuki. "W-well—"

Katsuki kisses under your right ear before he tugs on your underwear and flings them off to the side. He pulls back to devour your lips in a kiss, swallowing your noise of surprise. Your hands find home in his hair and he thumbs on the source of your heat.

You jolt and choke on a moan as he increases the mind-numbing friction. "Let me take care of you," Katsuki says; "let me, say yes."

"Yes," you cry out in his mouth. You feel floaty with the surge of lust shuddering through your entire body. "Please."

When you break away, you see his pupils wholly overtaking his iris, not even a hint of red. Katsuki licks over his teeth as he stares like he hasn't already eaten dinner. Like he’s doing himself a favor. You wrap tentative fingers around his wrist to guide his hand to your cunt, twitching because it knows it's going to be filled so well with Katsuki here.

Katsuki would make it so good; you know it. You know it so well. He’d know how you want it — need it.

He groans as you feel yourself get wetter. "Baby, shit — you needed this, yeah?"

"Katsuki—"

"I know." Katsuki rubs on the sensitive bud of your clit, kissing your jaw. "I know. Relax, baby, relax for me. Make it feel good. Just like that. Yeah, fuck, like that."

You feel dizzy. Katsuki teases one finger in, watching your face with rapt attention. You're so wet that he slides in easily; he could slip in two more just like that. But Katsuki is focused on making you feel the sensations instead, taking it slow, one by one, leaving you a fluttering, whining putty under him.

Katsuki’s heavy breathing makes you tighten around him involuntarily. He curses, patience rescinded. "One more?"

"Yes, please please — more — ah—"

He curls his fingers, and you tremble and whine, white-knuckled, gripping him, trying to meld yourself into him. Katsuki echoes your sound in a rasp, "Mm. You hear yourself? Fuckin' gorgeous."

It should be embarrassing that you're close already, yet who can blame you with Katsuki overwhelming your senses with every inch of his body — all over and inside you? His fingers are hot, and you're burning up, a coil in your stomach begging to be released.

Your legs shake as your back arches. "Kats — Katsuki — ah, please, please. Please, I'm—"

Katsuki kisses you through all of it. "I know. I know, baby. Don’t gotta beg. I gotcha — give it to me."

You thought you'd already exhausted all your tears, but Katsuki whispering in your ear and coaxing an orgasm out of you so tenderly pulls heat into your eyes. You forget about the weight on your shoulders. Right now, you can only think of how you could fall and Katsuki would catch you. You cry as you break, pulse jumpstarting, and Katsuki takes care of you all over again.

thinking abt gym rat katsuki whos all tough and bad but hes SO FUCKING CLINGY LIKE 💔💔 he texts you “baby i just finished my work out im sooo sore i need a kiss” or if you’re also at the gym with him, he makes you pause your entire work out so he can hold onto you or watch you when hes doing his reps UGHHHHHHH

katsuki swears he's the toughest, most intimidating dude in the gym — all sharp glares and bulging muscles, sweat dripping down his abs as he absolutely thrives through his sets. everyone around him is too scared to even make eye contact.

but the second he's done? this man turns into the world's clingiest boyfriend.

if you’re not at the gym with him, you’re guaranteed to get a text like:

"baby i just finished my set im sooo sore"

"need a kiss or im gonna die"

like he wasn't the same man who was just benching insane weights with a terrifying scowl just minutes ago.

and if you're there with him? oh, forget about focusing. he’ll straight-up pause whatever you were doing just so he can latch onto you.

"oi, oi, stop that—" he grumbles, practically manhandling you away. "babe. babe. i'm dying. gimme a kiss. please. hurts so bad."

next thing you know, this big, sweaty man is hugging you like you’re his personal recovery method, arms wrapped tight around your waist with his face buried in your neck.

"katsuki, you literally just deadlifted 400 pounds—"

"yeah and now i’m weak as hell. baby, c'mon. fix me. kiss me."

and if you're doing your reps? ohhh no. he'll straight-up stop you. like, you're mid-set, doing squats or something, and suddenly he's behind you trying to get you to stop.

"baaabe... stop for a sec. needa hold you. missed you."

"katsuki, i’m in the middle of—"

"so? just like... five minutes. i'll spot you after, promise. just lemme have you right now."

and don’t even get started on when you’re using the treadmill or doing cardio. this man will plop himself on the bench in front of you, arms crossed, pouting like a child while he watches you. every few minutes he's like:

"babe. babe. you done yet?"

"katsuki, i have ten more minutes—"

"nooo... can't you like... cut it short or somethin'? wanna go home and cuddle."

and if you try to push through your workout without stopping? he gets dramatic.

"why’re you even workin' out so hard anyway?" he grumbles, draping himself over you between sets. "your body’s already perfect. s'no point when you’re already the hottest thing in this gym."

"oh my god, katsuki—"

"nah, nah, 'm serious. c’mon. just skip that and come home with me. my arms hurt. i need my girl."

the second you both step through your home, katsuki barely lets you put your gym bag down before he's on you.

his big, calloused hands grab your waist, pulling you flush against his still-sweaty, rock-hard body. his lips crash into yours — desperate, hungry — like he's been deprived of you for hours, not mere minutes.

"missed you," he mutters against your mouth, his voice thick with need. "fuckin' missed you the whole time. couldn’t even focus right."

"katsuki," you breathe, trying to catch up with his fervor. "we were literally just together."

"don’t care," he growls, hoisting you up effortlessly. your legs wrap around his waist on instinct, and he carries you toward the bedroom like you weigh nothing.

he's on you like a man starved — like he’s convinced the only thing that’ll mend his sore muscles and aching body is you. his mouth is back on your throat, kissing, biting, groaning against your skin as his hands roam your body like he’s trying to memorize every inch of you.

"fuck, baby," he growls, voice heavy with lust. "you’re so fuckin' pretty. prettiest girl in the whole goddamn world, y'know that?"

his rough, calloused fingers glide down your stomach, over the curve of your waist, his touch lingering. "look at you. my perfect fuckin' girl."

your head spins at his words, and when his mouth finds your chest, he bites down gently on your nipple, groaning at the way your back arches for him.

by the time he lays you down, he's already tugging at your gym shorts. "need you," he groans, his teeth scraping against your jaw. "need my girl. fuckin' hurtin' without you."

you can’t help but laugh breathlessly. "you're acting like you’re about to die—"

"'cause i am," he insists, yanking your shorts and underwear down in one swift motion. "s'posed to be recoverin', damn it. how'm i gonna do that without my girl takin' care of me?"

his gaze drops to your cunny, pupils filled with want. his hands squeeze your thighs as he spreads you open, his mouth watering at the sight of your slickness.

"goddamn," he swears, his voice cracked with need. "look at this perfect little pussy. drippin' f'me already. so fuckin' pretty down here too, baby."

then, his mouth is on you, hot, wet, and starving. his tongue flicks over your clit, drawing a shocked moan from your throat. his strong hands pin your thighs apart, keeping you helpless against his relentless attention.

"fuck, baby," he groans, voice muffled as he buries himself between your legs. "missed this. missed how you taste. god, you're perfect."

your back arches as his tongue moves with purpose, alternating between slow, deliberate licks and quick, needy sucks. he’s not just eating you out — he’s devouring you, like your pleasure is the only thing that'll bring him back to life. every time you squirm or try to pull away, his grip tightens.

his tongue drags up your slit, slow and deliberate, before he sucks your clit into his mouth hard enough to make you cry out.

"there it is," he groans, voice wrecked. "there’s my pretty girl’s voice. fuckin’ love how you sound for me, baby."

your fingers claw at his hair, but he doesn’t let up.

"taste so good, baby. fuck. can’t get enough of you," he’s moaning like he’s the one being pleasured, rutting his hips against the mattress as he devours you. "this sweet little pussy’s all mine, yeah? s'only ever gonna be mine."

"katsuki—" you gasp, already teetering on the edge.

his tongue flicks faster, his grip on your thighs bruising as he practically pulls you into his mouth. "yeah, baby, c'mon. cum f'me. wanna feel you drench my fuckin' face. wanna taste my pretty girl's cum so bad."

and when you finally came — gasping his name, legs trembling — he didn't stop. if anything, he gets more desperate, lapping up every bit of you like a man starved. "fuuuck, yeah—there's my girl. goddamn, baby, you cum so pretty f'me."

but even as you tremble, he doesn’t stop. his tongue keeps working you through your high, licking up every bit of you like he’s trying to consume you whole.

he's crawling up your body, kissing you breathless with your own taste on his tongue.

"gonna make you cum on my cock next, baby. then i'll be all better, swear it," he rasps, his voice strained with need. "ain't done worshippin' you yet. lemme take care of you, yeah?”

‎‧₊˚✧[ it's me, kia ! ]✧˚₊‧ ｡ﾟ•┈꒰ა ♡ ໒꒱┈• ｡ﾟ ‎‧₊˚✧[ more of katsuki ! ]✧˚₊‧

⋆˚࿔ kia's note ˚⋆ lmao sorry, exam season and shit, hope you guys enjoy clingy (and a lil ooc) katsuki<33 will work on the 4k special soon!!

i love it when you read multiple works from a writer and you start being able to pick out the things that stick with them. like the themes they keep thinking about, that can’t be satisfied with just one poem or novel or story. or the motifs they like to reuse and recycle throughout their works like an extradiagetic thread. it’s like drawing a map through a writer’s collection of all the things that keep them up at night

cam girl reader and her sweet friend who sheepishly agrees to sleep with her for ‘content’, but ends up fucking her so good that it starts to look a little too real on camera.

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.
