Castiel's pace is just this side of too slow for Crowley's taste, but then he rather likes the slow build that brings and the sense of denial that comes along with it. If Castiel doesn't pick up his pace eventually, Crowley will say something, but for now he's content to lies with Castiel and let the slow sensation roll over him.

Crowley is a demon, yes, and he has no problem using and abusing all sorts of people, but his fondness for Castiel does have some genuine roots to it. He finds the angel fascinating and downright beautiful and if he's honest, which he'll only ever be with himself, he enjoys Castiel's company in some strange way that he can't explain. He can't exactly stand his ridiculous friendship with the Winchesters, but no one is perfect and Castiel just left them to come here with Crowley. That has to count for something.

Castiel's kisses only drive all of this home. The angel is so genuine in everything, hence he must like whatever this is with Crowley in some way. His hand slides into Castiel's hair, not to tug at it quite yet, but just to scrape his nails gently against Castiel's scalp as he exhales a shaky breath.

"I told you you could find something better to do with your mouth." The words are half-murmured and lack most of their usual bite.
