Sirius had never thought of himself as a particularly possessive bloke. After all, he had never felt that way about any of the birds he had snogged or briefly dated. Of course, that could be because a) most of the time they hung on his every word, and b) he obviously felt more for Remus than he ever had for any of then. When Remus said such things, it made his body thrum with excitement and happiness. He felt like he was unraveling as he lost himself to the sensations shooting through him. He became mindless as he fucked the other man from behind, his fingers curling into his skin, his breathing faltering as he nipped and kissed at whatever skin he could reach. He could feel himself losing control. The closer he got to the edge, the more erratic his movements became until he lost all sense of rhythm, pumping in and out of him hard and fast.
