Chapter Text
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 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.
“The fuck are you… smiling at?” Katsuki tried as he choked back moans, sighing with every thrust. "Shit, Eijirou" he hissed. Only he could make Eijirou feel like this- this good- he learned, and the feeling was undoubtedly mutual. The older man was sure that this is what heaven felt like.
“Ei, I’m gonna-” Before he could finish his thought- and his load- the phone next to Kirishima’s head vibrated from underneath the pillow. They both froze before Eijiro reached under the pillow to grab Katsuki’s phone and hand it to him. The movements came to a stop and he accepted the call after groaning in annoyance.
“What’s up, pretty girl?” He gasped, voice still gruff. Kirishima could hear Cho’s voice from the receiver and cringed. Her husband was still inside of him. “Oh, shit, I forgot about that. I’ll be there as soon as I can,” Kirishima frowned, as he noticed the sorry look in Bakugou’s eyes when they met, about to shift away before a firm hand was placed on his wrist. “Sorry again. Love you, too, sweet cheeks. Bye,” Katsuki threw the phone across the room as soon as he was sure he was off the call and stared down at his lover, his best friend, with a carnal grin.
“Now,” he started, garnet eyes glowing in the dimly lit room. Kirishima felt his chest bloom at the sight, lost in his own head. Even after all this time, he still blushes. “Where were we?”
...........
Katsuki couldn't help but admire Kirishima's selflessness, even as it intensified the turmoil within him. He grabbed the shirt from Eijirou's hand and dressed quickly, his mind preoccupied with conflicting emotions. They shared a lingering gaze before the blonde rushed over to him, giving into his inhibitions.
With a heavy sigh, Bakugou leaned in and pressed a tender kiss against Kirishima's forehead, a silent apology for the pain they both endured. "Thank you," he whispered, his voice filled with regret. "I'll make it up to you, somehow."
Eijirou nodded, his eyes filled with a mix of sadness and affection. "Just... take care, yeah? I'll be waiting."
