you always end up with your cheek pressed against the sheets.
no matter where it starts, or how slowly. there's something dug deep into that beastial side of his brain that's so terribly inclined for your attention, and the minute you're giving it, he's diving all in. like he's just waiting for it.
sometimes silently; on occasion, he'll follow you just about anywhere throughout the house, not making a peep, but lingering close enough that you can feel the heat of him seeping through your shirt. other times, he can't help but nudge the side of your head with his nose, maybe even nip your ear, even though your simply reading beside him on the couch or washing off veggies in the sink.
and you have to be careful, because the minute you run a hand across his shoulder the right way or reach up to idly fiddle with the ends of his soft ashen hair, he's on you.
crowding you into your space and smearing a messy kiss across the tender skin of your throat, hands big and wide and rough and coming up to cradle you everywhere, in all ways—the back of your head, the curve of your throat, the swell of your breast, the fat at your hips—as if he just has to. needing to be the one in charge, now that you've granted him the attention he wanted, refusing to let you slip away.
if he's not overtaken by his own lust, katsuki might even let you on your back for a while, panting against your naked skin and leaving tiny bites in his wake. and he'll snap his hips into yours with the kind of control any normal man might have and he'll kiss you until you're both swollen by it, a little messy with it, and he'll repress every shudder that threatens to turn him into something else whenever you gasp out his name.
but always, always—katsuki will fuck you from behind, eventually.
flip you over onto your stomach and hike your hips up into the air, spread your legs enough to accommodate him. you don't know if it's true—and later, when katsuki is a little more in his right mind and shy and embarrassed of his little heat, he won't explain himself—but it feels like he gets bigger, in some inhuman way; stretches longer, suddenly heavier as he wraps himself over your back, feels thicker and deeper inside your body than he did before.
he'll plant his hands beside your head, nuzzle into your cheek with a tortured sound from the pit of his chest, and rut into you like a fucking animal. and he doesn't stop when your knees start to shake or your hips threaten to fall flat to the bed; he'll only wrap an arm around your body to keep it close, to keep you from slipping away, and he'll carve himself inside of you until you're boneless and sure to be sore later.
(later, after he's finally let you take a shower—with his own body soap—and given you something to wear—his own t-shirt that you're not entirely sure is totally clean—he'll wrap up with you on the couch and refuse to acknowledge that side of him.
katsuki will shake his head and pointedly not look at you, but his frown will be obvious, where he's pressed it into your hair. "exaggeratin'."
"no, i'm serious," you can't help but grin, which only makes him press his mouth—and nose—into you a little harder. "nothing wrong with it, you just get a little...wild, is all. kind of...like a do—"
but you don't get to say anymore, because he bites at your cheeks until you squeal.)
