"You gonna be stayin' up late tonight babe?" Soft terry cloth roughs through damp red hair as Eijirou pokes his head into the living room, voice no louder than the movie playing on the television and shirt discarded in the laundry bin after his post-workout shower. He finds Katsuki sprawled out on the couch, an arm hanging off of it and the other laying on his chest—his large Doberman Pinscher, Soto, is splayed along his legs with his snout resting on Kat's abdomen. They both look so comfortable and content that Eijirou can't bring himself to try to dislodge either of them from their resting place. Besides that, he can tell it's a bit of a quiet night.
Katsuki doesn't respond, doesn't actually look up, eyes still glued to the TV. It's with a fond smile that Eijirou clicks his tongue twice and Soto, being Katsuki's trained and registered hearing dog, lifts his head and noses at Kat's hand. It's his silent signal that there's some sort of noise Katsuki missed, usually being that someone is trying to get his attention. They've developed a system where Soto knows that if Eijirou clicks at him like that, he needs Kat's attention, and will react accordingly. Red eyes look down at Soto and then up at Eijirou before the blonde signs. 'Yeah what?'
'You going to be staying up late?' is what's signed back, movements just a little bit clumsier than Kat's own JSL. They've been practicing together, Eijirou and Katsuki, spending a while every day going through the motions when they're both not too busy for it. The blonde has been signing for a while longer, though, having picked up learning when his hearing had first started to go, ever and always the over-achiever.
"I'm rewatching All Might's mid-career movies," Kat explains out loud, gently rubbing behind one of Soto's ears. The dog wags his little tail nub happily, shifts his head, and goes right back to sleep. "I'll be in bed before midnight. Got twenty of this and the last movie to go."
Eijirou smiles, the softest most tender smile anyone could possibly muster, made infinitely sweeter on him. "Alright babe. I love you," and he signs as he speaks, making absolutely sure the love of his life knows exactly what he's saying. It isn't always necessary but they've both gotten into the beginnings of a habit, Japanese Sign Language accompanying their day-to-day conversations more and more often.
Katsuki returns the smile, and although it's not quite as heart-melting as Eijirou's it is just as full of love, showcased in his own way. 'Love you too dumbass.' His own rough and tumble way.
But the redhead decides he isn't done and ready to say goodnight and he instead walks over, leaning down to kiss Soto on the top of his doggy head, earning another lazy stub-wiggle and a lazier snuffle and lick. Laughing softly at the pup, all breath and no substance, Eijirou leans in to kiss Katsuki slowly, passionately, and deeply. It leaves the blonde just as breathless as his boyfriend's laugh had been by the time they part. Eijirou smirks against his lips, just a bit, that little show of arrogance Katsuki gets to see more than anyone, and pecks him with a final chaste kiss. "See ya soon~" he hums, loud enough that he knows the blonde can hear him, close enough that he's nearly sure he can feel the rumble of his voice. To seal the deal, now just being an insufferable tease, he winks as he stands before he slings his towel over his shoulder and saunters to the bedroom with enough cock and swagger to fill the entire apartment.
It's totally playing dirty. It's playing so dirty and Eijirou knows it just as well as Katsuki, but Katsuki doesn't make it through the next movie. He shuts things down ten minutes before the credits on the one he's already watching and heads into the bedroom for the night, unsubtly locking the dog out (but just for a while.) It's not fair and he knows that this time he's lost their little game. To be fair though, he'd been playing empty-handed against Eijirou's fully stacked deck.
