Katsuki Bakugou Ao3 fics

illicit affairs by; Lokichoki

Summary:

Dynamight and Red Riot had a soft spot for each other since their time at UA, so it was no surprise how close they were, right?

Nobody- not even their spouses, knew how "close" they'd really become.

They were strong heroes, for sure, but in the end, they were weaker men.

They didn’t think it would end up like this at the start, really.

After Kirishima left their apartment to move in with his boyfriend, Bakugou would get calls at random times of the day because his old roommate still couldn’t do laundry to save his life. He would roll his eyes at the text, make a mental note to show up after patrol and arrive at the unwelcoming foyer of the redhead’s penthouse, always greeted with a sheepish smile.

Bakugou would lecture him to separate the whites from the colors, patiently demonstrating how it should be done each time. They’d had a few drinks before he was suddenly pushed out at a text from his friend’s fiance alerting him that he’d gotten off work and would be coming home. They’d exchange an awkward hug in the hallway, then Katsuki would be on his way.

When Cho moved in with Katsuki, the routine was similar. Eijirou would come over two or three nights a week while his girlfriend was on patrol and accept a home-cooked meal from his friend with a grin. He’d complain about the spice, and the blonde would scoff and shove him with an endearing smirk to match.

‘ Dude, how much chili powder did you put in this?’

‘As much as I want, idiot. I’m the one making the food, not you,’

‘Then let me make it! It’ll blow your mind, bro!’

‘And you’ll blow up my fucking kitchen, ‘bro’’

‘Come on, man! You love me,’

‘In your dreams, Ei’

That’s all it started as, honestly. Lingering touches and stolen stares between friends , the two of them terrified to cross the line into anything more.

But that- that was years ago. Now, Katsuki is married to a wonderful girl who loved him- a woman who was finally on his level- and now, Eijirou is married to a handsome man and strong, manly pro who- well, he was his husband, that’s for sure…

But now-

Now,  Eijirou is under Katsuki on his bed for the third time that day, chanting his name like a prayer while the blonde rolled his hips perfectly and thrust into him with a lustful grunt.

“Mmm, Kats… right there…” Kirishima moaned into Bakugou’s neck with hot breath, which was enough to drive him crazy. The blonde grabbed his hair forcefully and maneuvered his neck to look into his eyes. His breath was shaky as his movements slowed- painfully so- and the redhead couldn’t help but smile at the expression.
