His hands stroked along Remus' back, down his spine, until they reached his very delicious arse. He took one cheek into each hand and grabbed it, pushing their bodies into even closer contact, loving the way that his lover felt.
He had to come up to breathe, brushing his lips over Remus'. "Fuck me!" he whispered with a growing urgency. "Fuck me now, Remus." While there were no set rules in their love life, and they often switched positions, Sirius topped more often than not. But there were times when he liked to bottom, and this was one of those times.
