Katsuki jams the key into Izuku's apartment door, frustration only aided by the alcohol after fucking up unlocking a door eight times. Katsuki's legs give and the good-for-nothing piggy-backing nerd flops out of his grasp and into the floor head first.
'ah owww...'
Katsuki groans, rubbing at his temples. The blond slumps to sit in the open entrance of Izuku's apartment for who knows how long. Fuck, his head fuckin' hurts! Why the hell did he and the lightweight nerd even agree to show at Cheeks and Engine's engagement party? They're both on patrol early tomorrow morning. Speaking of... Katsuki glances over at Izuku, whose body is still daftly tangled in on itself in place of where the front door should be. He snorts.
'Fuckin' twat.'
Grabbing a leg, Katsuki drags Izuku's body out of the way for him to shut the door. Then he makes work of ridding himself and the nerd of shoes.
'C'mon, Deku. Into bed.'
The greenette mutters incoherent sounds, lashes fluttering around barely open eyes. Katsuki stares down at the man sprawled out on the floor with no care in the world about Katsuki's own well-being of having to take care of this precious fucking dork while being equally intoxicated. Every ounce of self restraint is going off in his head. He huffs out a breath, leaning down to pick Deku up by the waist.
'Kacchan...'
Katsuki pauses, looking down at wide green eyes staring up... in his general direction. 'What, nerd?'
Izuku just giggles back.
'UGH...' Katsuki continues his previous task of trying to lift Izuku off the floor, but his wobbly, intoxicatedly weak body cannot perform. 'Fuck. C'mon, Deku, you're not a dead weight. Help me out here-'
Heat. Warmth. Chapped lips. The sweet taste of sake mixed with some kind of spiced chapstick.
It ends as quickly as it started.
Katsuki drops Izuku, a head of curls hitting the floor again followed by another whine of pain. 'What the fuck Deku you just fucking kissed me what the fuck are you doing what the fuck!?'
The two have a... complicated relationship, at best. A relationship neither of them have cared to explore the parameters of. There are some things that are certain, though. A hero duo, on their way to opening a joint agency. Best friends, seen hanging out all the time outside of them seeing each other days-on-end at work. Katsuki's major pining dilemma for the past several years, a torture only very few friends have seen.
But, at what point will their careers not depend on each other being right there? At what point do best friends tire of seeing each other day in and day out? And, at what point does Katsuki's major nerd dilemma boil over?
Well, this is it. The best friend hero duo exploring the parameters of their relationship and the nerd dilemma boiling over.
Katsuki stares wide eyed down at Izuku, who's rolled onto his side with his eyes peacefully closed now. He reaches a hand up to his mouth, fingers wiping along his bottom lip that's still sizzling with heat and the lingering of spice. He would think he's completely sobered from that single moment alone if it weren't for his heart absolutely pounding in his ears.
'... Izuku...?'
Several seconds of silence pass before a hushed 'mhm' slips through Izuku's loose lip.
Katsuki seats himself next to the nerd, reaching his hand to poke him in the chest. Mustering all his strength to form words. 'Are... you awake?'
'Mhm...'
'What just happened? Did you mean to...'
'...'
'Izuku?'
The greenette sighs, rolling himself into a sitting position, glossy green eyes meeting red across the lightlessness of his own apartment. He giggles again, ducking his head down.
'What? Fucking hell Deku! What the fuck is so fucking funny right now?! Can ya fuckin' explain what just happened ya piece of-'
Izuku crawls over to crowd Katsuki's space, lightning crackling behind him as he presses his lips insistently against Katsuki's. There's a different kind of heat behind this as the greenette moves his lips against soft, stiff lips again and again. Katsuki finally kicks into gear and kisses back, hands caressing around freckled cheeks. Restraints gone. Passion meeting heat.
Izuku pulls back with a wet pop, breaths heavy and shallow as he meets glossy red eyes.
'Something that wouldn't have happened if we were sober...'
Katsuki sees green. And freckles. And more freckles. Even more freckles and... let's just keep it at it was a long, half-forgotten night for the "it's complicated" duo.
