"Well, I do. I want you." Sure, he wanted Moony and Prongs and Lily sometimes. A lot of the time, even. But he wasn't about to leave now. "Can't stop thinking about you, Peter," he said, slinging an arm around Pete's waist. It didn't even cross his mind that Peter might not want Sirius. That was just ridiculous. "I want you. I want to have sex with you," he said, in case it needed clarifying. "And I don't give a shit what anyone else thinks."
That last statement was probably the only thing he'd said that was influenced by the beer. "I need you." He leaned in to kiss Pete.
