It was over the Christmas holidays; Pete had gone home to visit his folks, but the other three had stayed at Hogwarts. Sirius would've rather have died than spend time with his parents (though he still worried about his little brother, of course). Remus was going through a rough part with his father, on more than just the werewolf thing. And James loved his parents. He was fine. He just wanted to beat Remus at his new Exploding Snap set, which was what he was trying to do right now. Sirius was watching them.
"Yeah you know, you're my friend, Moony," Sirius mused with his chin in his hand as he watched them play--Remus was winning, of course. "But I'd totally fuck you if you asked."
"What?" Remus looked up with a raised eyebrow. Sirius' cheeks heated up just then.
"...what?"
"You said you'd fuck him if he asked." James said helpfully. Both of them turned to stare at him, and he smirked evilly. What? He and Pete were waiting for them to get together already!
