"You make it easy," Castiel murmurs, voice breaking at the end as three fingers are pushed into him. He cants his hips on instinct, always greedy for more and never satisfied until he has Sam's entire length and girth inside of him. In theory he knows that it's smarter to take it slow right now, to make sure his body can even handle all of Sam properly. But in practice, patience is something he's always struggled with. "Sam, it feels so good..." And while honest, the fact that Castiel is talking is clearly a bit of a personal interpretation of Sam's command for Castiel to let himself be heard - because the fallen angel craves the praise, but has difficulty handling it at the same time, and is now trying to make sure there is none instead of allowing himself to bask in it.
