“Okay, who would win in a fight? All Might, or -”
“All Might. Obviously.”
“You didn’t even hear the second option!”
“Doesn’t matter.”
You send Katsuki a mild glare and he barely spares you a glance from his phone, only smirking when he sees your frustration. Your legs are strung across his lap, head laying on the pillows of your bed. Katuski’s eyes turn back to his phone screen, fingers occasionally scrolling. Normally you’d be fine with something like this - a bit of relaxation together, just enjoying each other’s company - but today you’ve decided you want a little something more.
“Fine,” you say, sitting yourself up a bit. A sly smile works its way across your lips. “Then what about you and me?”
Katsuki raises an eyebrow, then scoffs. “Sorry, sweetheart, but you’d lose in a second.”
“Oh, come on! I’m more powerful than I look.”
“Sure, whatever.”
“If you’re so sure that you’d win,” you start, and when Katsuki meets your eyes you make sure to bite your lip. You take note of his gaze flickering to your lips then back up to your eyes. “Then why don’t you show me?”
He pauses, eyebrows furrowing. “Do you want to fight… or fuck?”
“Your choice, babe,” you grin.
And then Katsuki is putting his phone on your bedside table and pushing your legs off of his lap only to settle in between them, arms holding him up by your head. His kiss is rough, needy, but you giggle onto his lips, slinging your arms around his neck. It’s not long before you’re in the middle of a full-blown make out, Katsuki’s hand sliding just under your shirt. His fingers are hot and you shiver into their touch, not missing his smirk against your lips.
He moves his mouth down to your neck, and you stretch to give him room. Your eyelids flutter as soft sighs leave your lips (which are now probably red from Katsuki), fingers tangled in his hair as he goes to work, leaving marks all over your throat.
You turn your head to the side right as his phone vibrates on your nightstand, and from what you can see, it’s a text from Kirishima. You’re about to ignore it until you fully register his lockscreen because holy shit that’s you.
“Wait, wait,” you say breathlessly, and Katsuki departs from your neck, sending you a confused (and mildly annoyed) stare. You reach for his phone, eyes glinting with a new goal.
Katsuki reaches it before you do.
You curse him in your mind as your head snaps back to him, and he’s just about fucking cradling his phone to his chest. Your smile is too wide as you look between him and the phone.
“Am I your lockscreen?” You ask, amusement evident in your voice.
“What? N-”
You tackle him before he can finish his denying sentence, hands immediately gripping for his phone. He lets out a yell as you clamber on top of him, somehow managing to overpower him and take the phone from his grip. You tap the home button, and the phone alights, showing none other than you.
It’s a relatively new picture, one you’d sent him a week or so back when you were hanging out with Mina in your room and he was out at the gym. It’s nothing fancy - the original picture is of both you and Mina, faces pressed together and grins wide, but Katsuki’s cropped the other girl out of the picture.
“Ha! I am!”
“You weren’t supposed to see that,” Katsuki grumbles, and your chest swells with warmth. You can’t contain your smile as you look down at him from your position on his hips, then lean down to press a kiss (much more innocent than the ones before) to his lips.
“How about I make you my lockscreen too?” You ask, climbing off of him to get your own phone. You’re sure you have a least one picture of Katsuki that isn’t terrifying.
“Whatever,” he says, but you don’t miss the smile in his voice.
