Work Text:
izuku truly hated his work schedule.
really, who on earth would want to work a nine-hour night shift? it only meant he would have to come home at the worse hours.
though, it paid well. which is why he stayed.
that did not mean that a certain blond would be able to get so used to it.
after many attempts at stabbing izuku at ungodly hours due to assuming he was a home invader for coming home so late, katsuki had taken a while to get used to his boyfriend's schedule.
and eventually, they both did. though it only brought another problem to the table.
see, izuku's schedule often meant that katsuki would be alone at night. and the blond hated it.
especially since the night was often the time he felt that he needed izuku most.
and yes, he tried to please himself during the many late nights, yet nothing quite worked as izuku would.
so, as the days went by, katsuki began to become sexually frustrated in the most obvious ways. he was louder. yes, somehow the fiery blond could get even louder.
izuku noticed this, the blond's obvious aggression due to his unspoken wants. katsuki hadn't spoken up on his problem, he often never did as he did not want to get in the way of izuku's work.
and so he only yelled more, complained about every little thing, and grumbled until he looked as if tears were daring to fall from his very eyes.
and it all broke izuku's heart.
his work was very cruel, and straining for both of them, he thought.
and so while izuku was on his way home from his late-night shift, he had an idea.
the green-haired male drove peacefully, slightly eager to get home. though, it was not far at all. so he hummed, speeding up the slightest bit, the road was pretty vacant due to how late it was.
in no time, izuku was home. he entered quietly, taking his shoes off and locking the door behind himself.
izuku silently padded to him and katsuki's room, pushing past the already cracked open door.
and there he was.
katsuki was sprawled out on the bed, clad in nothing but izuku's large button-up pajama shirt. the green-haired male smirked at the sight.
"kacchan," izuku whispered. though, the blond did not respond. he was asleep, obviously.
izuku silently approached the edge of the bed, kissing the blond on the cheek before climbing onto the bed. slowly and carefully.
he moved carefully, his hand now at katsuki's thinly clothed waist as he held the blond. "kacchan.." izuku whispered a bit more clearly, now with the intent to wake the precious blond from his sleep.
katsuki only hummed, shifting slightly yet never actually waking up. though, due to his movements, his neck was now exposed, revealing how bare it was. unmarked, showing how long it'd been...
and izuku couldn't help but feel bad.
though, he had the full intent of making up for it as he leaned down into katsuki's neck, leaving soft, feather-like kisses. katsuki stirred at this, his neck was so sensitive.
"ah-.." katsuki let out a soft, broken moan at this. izuku's breath hitched at this, his blood now rushing. the sound pushed izuku to go further, his movements now a bit rougher, faster.
izuku then slipped a hand between the blond's legs, feeling as katsuki flinched softly before opening his eyes.
"wha- fuck.." he breathed softly, his confusion immediately shifting to pleasure as izuku slipped his hand down further, softly grazing the blond's puffy clit.
izuku smirked softly, "i forget you're such a heavy sleeper." he chuckled, applying a bit more pressure this time.
katsuki gasped, squirming until he was laying flatly on his back. his legs were spread far, giving izuku full access as his pussy already throbbed intensely, slick drooling out lazily.
izuku only moved faster, circling the blond's clit until katsuki's chest began to rise and fall heavily, his hips bucking up into izuku's hand ever so slightly as he grew closer and closer.
though, izuku soon pulled away. katsuki whined, his sleepy eyes still half-lidded. "you're so wet... were you doing it without me?" izuku whispered, his hands sliding up to grip at katsuki's thighs, refusing to touch his eager clit.
"mhmm.." katsuki hummed, nodding his head slowly as he remained heavy with sleep. "oh," izuku said simply before his smirk widened, his eyes now dark with lust. "but i told you to wait, kacchan."
katsuki whined at this, nodding before speaking. "'m sorry... i needed to." he mumbled.
katsuki's apology seemed to have struck something in izuku, he was so soft, almost passive in such a sleepy state. it only made izuku feel more powerful, in control of the usually demanding blond. he wanted to go further until katsuki could only cry beneath him.
izuku hadn't responded, only swallowing the blond's lips into a heavy, tongue-filled kiss. katsuki could hardly gasp before he then felt two thick fingers immediately fill his cunt, thrusting harshly without hesitation. katsuki's moans were muffled by izuku, his tongue gliding along izuku’s.
soon, katsuki slipped his hands down to izuku's, attempting to get him to ease up as he'd been so rough. izuku furrowed his brows in response, pulling away from katsuki yet their lips were still mere inches apart.
"move your hand." izuku spoke sternly, his voice cutting through the thick air.
with a sharp gasp, the blond instinctively went limp, his hand falling only for izuku to grab them both with ease. his larger hand completely encased the blond's wrists, keeping them locked in place above his head.
"fuck-! i'm gonna cum..." katsuki moaned, legs trembling as he felt another finger be added. izuku then began circling his puffy, reddened clit with his thumb.
the blond's eyes immediately shot wide open, "haah... izuku!" he cried loudly as he finally came, his legs trembling, and his back arched deeply in an attempt to pull away from izuku.
though, he didn't stop.
"fuck-! izuku please.." katsuki begged, slowly becoming overstimulated. his chest rose and fell heavily as he squirmed around frantically, attempting to close his legs. though, he was stopped by izuku's larger body, forcing his legs apart.
izuku gazed down at katsuki, his skin a deep shade of pink, and his eyes looked as if a tear were about to spill from them at any moment.
he only went faster, harder. the blond's expression only spurring him on further as he now began to rut against the sheets, his dick bulging in his pants.
"ah! f-fuck.." katsuki cried out as his eyes began to roll beneath his lids, his legs shaking even harsher before his jaw went slack, his breaths frantic.
izuku continued, curling his fingers slightly upward with each smooth thrust until he felt a warm, heavy stream hit the palm of his hand, wetting both his pants and the sheets.
it was then that he slowed down, watching as katsuki squirted all over the sheets and his hand. "shit," he cursed softly at the obscene sight.
katsuki only cried, tears slipping from his now squeezed-shut eyes. the overstimulation hurt a bit at first, but now he felt so numb yet so... good.
he was so far gone that he hadn't even realized izuku had let him go. his eyes remained closed yet he continued to cry softly.
izuku watched it all, as katsuki came down from such a numbing high only to be racked by such intense emotion. he didn't hesitate on picking the blond up into a warm embrace.
katsuki returned the hug weakly, crying softly as he sat on izuku's lap. oh, how he missed this. "you did good, kacchan. so pretty..." izuku whispered soothing praises into the blond ear, rubbing soft circles into katsuki's back.
katsuki hummed as they sat there for a short while, allowing katsuki to calm down. soon, the blond gazed up at izuku, his eyes slightly lidded.
though, izuku could see the returning lust in those vermilion eyes. his hands fell to katsuki's plush thighs, his breath hitching before he leaned in for another kiss.
katsuki eagerly returned the kiss, his hands hastily reaching for the front of izuku's pants. his hands were clumsy as he messily fumbled with izuku's belt before it eventually became undone.
he then unzipped izuku's pants to reveal his aching cock. izuku groaned, nearly bucking his hips upward as katsuki's soft hand began to stroke him. as katsuki went, his fingers couldn't touch when wrapped around izuku's length.
"fuck," izuku hissed into the kiss before letting out a soft, shaky moan. katsuki felt an intense throb in his cunt at the sound of izuku's moan.
katsuki's hands were so soft, that he could easily get lost in the feeling of pleasure. his grip tightened, eventually pulling away from the kiss and allowing his head to fall onto katsuki's shoulder.
katsuki felt his face warm at this, listening to izuku's heavy breaths as they brushed along his neck. before long, katsuki felt himself being lost in the pleasure as well, his hips grinding against izuku's clothed thigh.
izuku inhaled sharply at this before he pulled away, picking katsuki up and pressing him against the bed. katsuki was a bit surprised by the sudden action before he felt the blunt head of izuku's cock at his cunt.
the larger male lifted katsuki with ease before hastily thrusting into him. katsuki cried out at this, there was always a slight stretch. it kind of hurt, but katsuki liked the pain.
they remained like that for a while before katsuki gave izuku the 'okay' to move. and without hesitation, izuku began to move his hips into the slick heat.
it took no time for katsuki's moans to fill the already thick air, his legs threatening to tremble yet were stopped by izuku's larger hands.
izuku groaned softly at the feeling before nearly bending the flexible blond in half. katsuki's thighs were pressed against his stomach as izuku thrusted into him harshly, using him solely for pleasure.
katsuki practically melted under izuku, still so sensitive from his previous orgasms. his words were nothing more than a mess of whiny mumbles as izuku manhandled him.
the green-haired male leaned in, taking katsuki's lips into yet another hot, rushed kiss before speeding his thrusts. izuku had grown so rough that the bed itself began to creak with every thrust.
they were both so lost in the pleasure before izuku eventually felt himself growing closer to his orgasm inside of katsuki.
their movements were a flurry of lustful touches, high-pitched moans until they both came. izuku pulled away from the blond's lips as he let out a deep, stifled groan as he finally released inside of the blond.
katsuki's eyes were fully lidded, his jaw falling slack at the feeling of izuku filling him so perfectly. his entire body buzzed with the feeling of yet another intense orgasm.
though they both soon came down from their highs as izuku pulled out, releasing katsuki as the blond sighed.
"i'm sleepy." katsuki whispered before looking to see that the sun began to rise. he groaned, turning away.
izuku only laughed softly, "sleep, kacchan. i'll clean up." he said, kissing the blond on the forehead. the blond immediately shook his head at this, "no, you've been working all night, then this.. you're probably exhausted. i'll help."
izuku thought about it all for a short moment before nodding with a hum, "alright." he said with a knowing glint in his eyes.
izuku then stood up, fixing his pants before walking over into their bathroom. katsuki attempted to follow him, rising from the bed before promptly falling onto the floor.
the blond let out a yelp at this. his legs had given out from beneath him, completely shaky.
"deku!" katsuki shouted, causing izuku to turn around quickly. the green-haired male then looked down at katsuki before grinning.
katsuki then squinted his eyes, "you knew my legs were weak!" he shouted. izuku then burst into a fit of laughter, his smile so wide that if katsuki weren't so pissed, he would likely find it cute.
"fine, i'm sorry. i'll help you up now." izuku said before picking the blond up with ease. katsuki grumbled at this, "this is all your damn fault! i hate you."
now, katsuki was nowhere near as soft as he was in his previously sleep-ridden state. the loud, demanding blond had returned. just as izuku liked.
"oh kacchan, i love you too."
