Usually Crowley's pet names seem either meaningless or mean-spirited, but not that one, not right now. Seeing Crowley's reaction to the bite is inspiring; he wants to see more of that, he wants to see if he can make Crowley feel as good as he did for Castiel. He doubts that's possible. Yet. He's going to try his hardest and learn as much as he can now. Obtuse he may be about some things, but he's a soldier, and he can learn the important things quickly.

He hums into the kiss and returns it eagerly, grateful both for it and for the assistance, not to mention the highly erotic experience of being guided on Crowley's cock by Crowley's own hand. He follows the instruction well, increasing his pace, and he makes a mental note to keep things increasing steadily at this pace. His goal is to send Crowley over the edge without needing any more help now. The idea is something he thinks he could be strangely proud of, and maybe Crowley would be proud of him too. He doesn't think that's necessary, but it's... nice.

He makes an executive decision and drags his fingernails down Crowley's back, pressing as hard as he thinks Crowley might enjoy.
