hickeys and bite marks

summary: Katsuki doesn't realize Izuku's gay until he sees him fooling around with Kirishima.
(and now he's jealous.)

warnings: (slight) lemon around halfway into the chapter

THIRD PERSON

Bakugo stares longingly at Izuku from his desk at the front of the classroom. It was blatantly obvious how Round Cheeks looked at him, trailing one hand softly down his arm and puckering her lips whenever he turned his gaze her way. Hell, as far as the class could tell, he liked her too.

Their conversation was barely audible from so far away in the bustling class, but as Izuku lifted to drape both his arms against her shoulders and lean his face in, suddenly the room went quiet. Uraraka blushed violently, but Izuku kept leaning in.

"So what you're telling me is that fruit loops overclass cheerios?" His voice was teasing and strangely alluring. "Look me in the eyes and say that again because you obviously haven't tried-"

Kirishima stalked to the front of the classroom suddenly and took one of Izuku's arms to pull him out of the classroom. Still facing Uraraka, he followed Kirishima with his eyes to the point where he was caught by the arm and dragged out, laughing a full, content and strangely confident, laugh.

Izuku's presence had filled the classroom, and suddenly, it was gone.

Izuku's lips met the underside of Kirishima's neck and trailed soft kisses back to his mouth, gulping down his heavy breaths. "Don't flirt in class like that." Kirishima growled as they separated for air.

"You gonna make me yours?" Izuku dove back into a heated kiss.

Kirishima paused for a second and squeezed his hips with hardened fingers. Izuku moaned and reached one of his scarred hands to balance himself on the bathroom stall's red doors. "No. I'm not outing either of us yet." It looked like it physically pained Kirishima to say it out loud.

Almost bored of the conversation already, Izuku made quick of unbuttoning the front of a dishevelled white shirt to continue licking at the skin there. Kirishima sucked a deep breath in, suppressing small whimpers. He grabbed the downside of Izuku's face and shoved them back together, biting on his lower lip. In turn, the boy thread his fingers in vibrant red hair he'd helped to re-dye just weeks ago.

Izuku yanked softly and got off of Kirishima's lap to straighten his own dress shirt, leaving Kirishima to look at him with need in his soft red eyes. Pawing at the lock, the stall was opened for Izuku to stare at himself in the mirror by one of the sinks. Kirishima left after him, buttons securely tied as he outstretched both arms to place beside Izuku's on either side of the sink, as if to trap him in, as he pressed his back flush to his.

Izuku smiled lazily as Kirishima dove to suck at the skin connecting Izuku's neck to a soft collar. "We're going to hell anyway." Izuku shrugged his shoulders ever so softly to push the other off.

Kirishima chuckled softly from the back of his throat, pulling Izuku in sideways for a short kiss: all messy lips. "Don't say that." He tried to pout. "We're heroes, Izu-kun."

As the redhead left the bathroom, Izuku looked back into the mirror, scowling as he made out a dark red mark where Kirishima was licking not too long ago. That motherfucker left a hickey. The ends of Kirishima's lips tilted upwards slightly from the hallway.

Kirishima walked back into class around ten minutes before the free period was to be over, marking the in-between of their math and hero history classes. He soon dove back into conversation with Jiro and Denki, and the class ignored his presence.
