deku groans, dragging his stiff, creaking bones through the threshold of his and katsuki's shared apartment. he felt like his ever so sturdy legs would give out on him at any second. he stripped off his hero suit, flinging the pieces all across the living room couch, stumbling as he kicks off his boots. if he were any more aware of his surroundings, he'd notice the similarly haphazardly thrown black and red hero suit lying about the apartment too.
clad in nothing but his birthday suit, he walked down the hallway that lead to the bedroom. as he gripped the door handle, he felt the trickles of rut swim through his body. shit, when was the last time he and katsuki had fucked? he almost laughed at the thought, when was the last time he had the energy to even /think/ about fucking? he groaned, even if katsuki were home, they're both too tired to do shit about his rut anyway. he opened the door and was greeted with his mate spread out face down, star fish style on their bed. katsuki just as bare as izuku, and honestly the alpha might've laughed at the goofy position of his mate if he weren't so tired.
he noticed all the bruises and scratches that littered his mates body, and mustered up the energy to growl. izuku hated very little, in fact he rarely used the word hate at all. but god damn, seeing his mate in pain really made him fucking /hate/ villains. but even battered and bruised, and in one of the most unattractive positions possible, katsuki still managed to look gorgeous. he winced as he felt his cock throb, desperate for katsuki's warm hole. the alpha stalked towards the bed, resting a knee on the edge. he turned katsuki over, facing him towards the ceiling. crawling up the bed, he slotted himself between the omega's legs and took a deep breathe.
he had to get a grip, he was so tired he felt like he could fall asleep sitting up, but if he didn't get inside his mate soon his rut would hit full force and last for who knows how long. sitting back on his ankles, he reached a hand out and cupped katsuki’s face. he missed his mate, the alpha hadn't seen him in two whole days. he huffed as he scooted forward, using the arm that had been holding the omega to now brace himself against the bed. the other hand lining himself up with katsuki's cunt.
he pushed in slow, not wanting to wake the omega from his sleep. once finally sheathed, he groaned out a small /fuck/ in pleasure. damn, how could he ever forget how perfectly warm and tight his omega was? even on the brink of passing out, he still managed to rock his hips a few times, but had to stop not long after. he sighed, he really just wanted to fuck his mate, but just the thought of it made his body ache in disapproval. he situated himself and got comfortable, stretching his legs out and resting his head on the omegas shoulder. unintentionally stirring the omega out of sleep.
"mmm- long day deku?" the omega didn't bother to open his eyes, too tired to bother. deku nodded, nuzzling into his mates warmth. "mhmm, too long"
"take down any shitheads?"
deku chortled, his mate blunt as ever. "yeah, too many to count."
katsuki hummed, "yeah-" he cut himself out with a yawn, "me too" the omega blinked his eyes open, and sniffed the air. "hmm, rut?"
deku groaned, annoyed. "hate ruts, the worst" katsuki lightly nodded. "me too, fuckin' hate heats." katsuki threaded his fingers through deku's hair and rocked his hips. he shut his eyes, mumbling out a quiet "missed alpha's cock"
the alpha sighed, "such a tease." the omega laughed, airy and tired, "shut up and go to sleep, stupid alpha." the alpha smiled sleepily and pushed himself in deeper. "good night."
