"Come on, mate, come for me, come on," Sirius muttered demandingly.
Sirius pulled hard, twisting his wrist as he went from base to tip and then swiped his thumb across the tip once more. Fumbling between their bodies, he wet his fingers and then pulled on Fabian's cock with both hands. "Let go, you know you want to. Just let go and come for me."
Another tug and then Sirius grinned against Fabian's flesh. Dirty talk had gotten such a fantastic response before so he decided to do it again. "Next time? I want to suck you off, feel all this," Sirius squeezed Fabian's cock, "inside my mouth, lick you and taste you. I bet you taste fucking divine. You want that? Your hands in my hair as I suck you into my mouth so deep? You fucking my mouth?"
