A/N: Written for the prongsfoot-microfic July 5 prompt, 'Couple', over on tumblr.

"Oomph." Sirius is woken from his nap on the common room sofa by James dropping on top of him.

"Did you miss me?"

"I miss my ribs…." Sirius groans as James squirms to make all 12 stone of himself comfortable, but wraps his arms around him anyway and accepts his kiss as he finally settles. "How was detention?"

"Excruciatingly boring," James complains into his neck. "But it gave me a lot of time to think."

"Uh-oh." Sirius snorts and nibbles at his ear.

James gets up on his elbow to look down at him. "About you…."

With a devious grin, Sirius runs his hands down James's side and kisses his jaw. "About my… skills?"

"Oi!" Remus calls from the floor where he's battling Peter in a game of chess. "Take it upstairs."

James ignores him and brushes a stray lock of hair from Sirius's face. "Well, it was a rather long evening—but I wanted to ask you something."

"The answer is always 'yes'." Sirius smiles, cupping his arse and trying to steal another kiss.

"No, not that, you wanker. But do you wanna like… be together?"

"James, you are literally on top of me."

"No, I mean… do you wanna be a couple?"

Sirius pulls back and gives him a weird look, something between a squint and a frown. "Erm, James…. I don't know where you've been, but we sorta already are."

"We are?"

"Considering we've been snogging and shagging for four months, I'd say so, yeah."

"Ew, lads, too much information!" Peter covers his ears.

"Shut up, Wormtail, we're having a moment," Sirius says and turns back to James. "Are you telling me you've been running around shagging other people all this time?"

"What, no?! Have you?"

"Of course not."

"Well, good. So, we're a couple?"

"Yes, Prongs. We're a couple," he says with an air of someone indulging a child. Then he laughs and shakes his head. "I can't believe you didn't know that."

James punches his shoulder. "How was I supposed to know?"

"Oh, c'mon. Even Moony knows. Isn't that right, Moony?"

"I thought I told you to keep me out of this stuff," Remus says without taking his eyes off the chessboard. "But yes. Of course I know. The whole castle knows."

"See?"

"Honestly, James—it's a wonder you can even sit on a broom with such a thick head…" Peter says, wincing as Remus's Queen takes his Bishop.

Sirius almost knocks James to the floor in his haste to extract his wand from his robes and a second later, Peter's head has swollen to twice its usual size. Peter screams and clutches it, knocking over the chessboard as he springs up, pieces flying everywhere, but Sirius and James pay him no mind.

"Oi, stop snogging and set him right!" Remus says, trying to keep Peter from stumbling into the fireplace in his panic.

"No. He needs to be careful about whose boyfriend he insults." Sirius says, threading his fingers through James's hair and pulling him back down.

James's grin grows even wider, and the outside world is lost to them.
