Chapter Text
Keigo hated the spring. He despised it. It seems like an awfully strange thing to hate, most people enjoy seeing frost finally melt, flowers blooming in the fields and cute baby animals. But spring was just a giant hassle to him, a reminder of how he was different, how he was weak.
To put things simply Keigo is part Avian, although not as bird like as some other Aivians he still got some bird attributes thanks to his quirk. Like the wings, duh, perching on tall things, cherpping for food, obsessively preening himself and mating for life- he hasn't achieved that yet but he desperately wants to. But none of them is more of a pain in the ass then mating season.
His brain is programmed so that every spring since he was fifteen, he wants to find an appropriate mate, court said mate and then.. breed them.
So usually he spends the first few weeks whining about having no mate and then the last couple bed ridden. Usually from a deep depression or insane levels on neediness and horniness. It's truly embarrassing. He's a grown, relatively strong man completely debilitated by the need to mate.
Unsurprisingly being practically raised by a company isn't helpful in the scenario. The HPSC aren't known for being the nicest to their heros, so Keigo was never aloud to court a mate. What if the news got out? It would create too much attention on the wrong things and they can't have that. They don't want their heros looking like sex drived perverts either.
At first they thought something was wrong with Keigo. These 'heats' started in his mid teens so at first they didn't take them seriously. The Heros Commission thought it was some weird teen-age thing, plus with his early life it wouldn't be surprising for Keigo to be a little odd in the head. But once they did enough research on Avian type quirks they quickly understood the problem.
Most of Keigo's heats are spent locked in a dark, dingy room with barely enough things to create a nest. He spent the week jerking off, fucking his fist while sobbing. And it was starting to get to him.
Keigo groaned into the pillow. The air was hot and sticky and the humidity was thick like a blanket. The room was dark. Keigo had tried his hardest to block out light coming in from the windows, making sure nobody would ever see him like this. Keigo's 'personal heat room' was in some hidden part of the HPSC building. The walls were plastered that boring corporate white and the floor was the dirty stone that would usually be covered with fake wooden panels. It definitely wasn't the most appropriate room to spend spring in, but Keigo was used to spending his time down there. It was grimy but it felt like home to him.
In the centre of the room was his nest. It was a mattress with piles of pillows and blankets to make it cozy and as nest-like as he could create. The pillows consisted of the well worn down ones from his actual bed and whatever else he could find. There were some soft, fluffy ones and there were some uncomfortable decorative pillows he had taken from sofas around the office building. Keigo had arranged them into circular walls for the nest and pulled a large blanket over it all.
His aching cock twitched against his thigh painfully. He had been rock hard for hours and he felt like he was losing his mind. Pre-cum beaded down his shaft, leaking out his slit. It rubbed onto his thighs and sheets making him a hot and sticky mess. Keigo was covered in his own cum as he failed to make his erection go down like the desperate, pitiful man he is.
Keigo desperately wanted- needed a mate. He needed a warm, wet, hole to shove his cock into, to pound into until they both couldn't think, to breed and stuff with his thick cum. But he didn't have that mate. He had a half stuffed pillow he could hump and his fist he could fuck.
His wings caged around him as he curled up in shame. Shielding himself from peering eyes he felt staring into his back. Nobody was there, he knew that. But the feeling wouldn't go away. He let out a desperate almost broken groan as began humping one of the pillows in a futile attempt to release the ache from his angry red cock.
Keigo felt truly pathetic, he was a grown man, one of the top heros in the country - but he turned into such a mess just because he wanted to fuck. The shame clouding and distracting his mind made it impossible to cum. He couldn't focus on the feeling, or imagining someone was there with him. He tried to picture a mate to fuck but he couldn't think of anyone. His head ached and he wanted to cry. But his erection wouldn't go down. Keigo's eyes stung with tears as he frotted into the pillows trying to cum.
White ropes of hot cum spurted out his cock and onto the pillow and he just felt miserable. There was no feeling of relief or pleasure in it anymore. His golden blond hair stuck to his forehead, sticky with sweat. Keigo's whole body shook. His usually strong and hard arms were shaking like leaves. That was probably a sign to rest. Rolling to lay flat on the sex soiled sheets, he groaned.
Keigo's cock ached, it was hot and covered in cum but at least it had gone down now. He felt his eyes screw up and his face turn into a frown. He didn't fight the tears anymore, he just stared up at the blank ceiling and let them fall. His vision went blurry as he felt them slip down his cheeks.
Keigo cried himself to sleep, for the third night in a row.
It was only early in the mating season so he still had over a week left. When it was early spring Keigo could usually get away with working for a few days before being rendered completely useless. Which was great news to the HPSC, and not so great for Keigo. Technically he was a functional person, but his head always felt fuzzy, unsure. He was always listless when it came to actually working. And he could be easily distracted with anyone on the street who had 'mate potential'. So Keigo was never kept on patrol for long.
As Keigo got nearer and nearer to his mid twenties he was getting to an age where he almost physically needed a mate. He was used to loneliness. Soul crushing, heartbreaking, everlasting loneliness. It was apart of his job. But it was starting to effect his every day. Even outside of mating season.
It got really bad when he caught himself collecting bottle caps to potentially court the villain Dabi.
