Work Text:
Nagisa knocks on the door. He bounces on the balls of his feet, nervous, but the door opens before long.
“Nagisa,” Gakushuu greets, smiling, “Come in. The principal is in his study.”
Nagisa smiles, relieved. The principal was the only person he was really nervous about seeing.
“Thanks for having me,” he says, as he walks in and slips off his shoes, “I brought my books because I figured you’d want to study a bit.”
“You know me so well,” Gakushuu muses, then grabs his hand and interlaces their fingers to drag him upstairs, “We’ll start on maths first.”
Nagisa chuckles, endeared by his nerd of a boyfriend.
They make it to Gakushuu’s room, a kind of bland place, and he sets his books on the desk. He turns, planning on sitting on the floor like he expected to study, only he squeaks as arms wrap around his waist and he’s tugged into a firm lap.
“G-Gakushuu!” he stutters. Gakushuu smirks at him, head making itself comfortable on his shoulder. They’re both at his desk now.
“There’s always room on my lap for you,” he says, “No need to use the floor.”
Nagisa knows his face is red. He wills it down(and kind of fails) before opening his maths textbook. Gakushuu keeps his arms around his waist and they both start working.
An hour later, Nagisa feels like his head is about to explode.
”I’m done,” he mumbles, patting Gakushuu’s arm, “My brain is going to melt.”
Gakushuu makes a noise of disappointment but he does let him go, letting Nagisa get up and flop on his bed. Gakushuu watches him as he curls up over the covers before turning back to his work.
He’s bored about ten minutes later. Glancing to Nagisa again, he sees him absently playing with a loose string from his bed sheets.
Gakushuu stands up and walks over, crawling over top of him. Nagisa turns on his back and blinks in confusion.
Gakushuu stares at him for a moment, then leans down and locks their lips. Nagisa makes a surprised noise but cups his cheeks, tilting his head up to deepen it further.
Gakushuu uses one hand to hold himself up over Nagisa, the other moving to run over his side and down his waist, squeezing. Nagisa squeaks a little. Gakushuu always finds that noise so cute.
Nagisa’s hands move from his cheeks to his hair, nails scraping at his scalp lightly. Gakushuu grunts, and prods his tongue between his lips. Nagisa parts them, letting the muscle slide in.
He moans softly, and Gakushuu smirks into it, running his tongue all along the inside of his mouth, curling around Nagisa’s own tongue and sucking lightly.
“-I’m going to be making dinner-“
Gakushuu jerks back, falling off the bed. Nagisa wheezes, hands slapping over his ruby red face.
“Dad!” Gakushuu yells, “Knock before you enter!”
“Oh,” Gakuhou says, eyes flicking between them, “My bad, then. Keep it down though, would you? And use protection-“
“GET OUT!” Gakushuu screeches, “THAT’S NOT WHAT WE WERE DOING!”
Gakuhou smirks but shuts the door, not before chucking something at him. Gakushuu catches it and looks to see it’s a box of condoms. He throws it as hard as he can, and it slams against the door with a thunk.
Gakushuu turns to look at Nagisa. He’s still hiding behind his hands, and he can practically see the steam radiating from his face.
Sighing, Gakushuu stands up and slips into the bed again, this time simply wrapping his arms around Nagisa. The boy peeks through his fingers, looking at him.
“The principal is stupid,” Gakushuu mumbles, and presses his lips to his neck, “We’re just not going to talk about that.”
“Agreed,” Nagisa sighs, turning and wrapping his arms around him. Gakushuu hums in delight and nuzzles closer. He always likes cuddling with Nagisa, even if he won’t admit it aloud. Nagisa doesn’t need him to, though.
