Sirius slid his lips closer to Remus’s hips as Remus’s breath came in ragged gasps. The deeper Sirius took him, the harder he got, and the sensation of Remus’s cock thickening in Sirius’s throat was one of the sexiest fucking things he’d ever experienced. Sirius felt his own cock throbbing and leaking, rock hard between his legs, and he reached into his shorts to stroke himself as he worked Remus with his throat and tongue. He slid his other hand up the back of Remus’s thigh and squeezed his arse hungrily, remembering Remus’s promise to eat him out, and own his cock twitched in his hand at the thought.
