It's all too easy to hum contently again, chin barely tipping up towards Lucifer's fingers. At the very least, in a peculiar kind of way, he really can't help but find the petting comforting.

Dean can only appreciate the comment, not entirely sure how much he'd be expected to learn otherwise but willing to do what he can with what he has. Back to bobbing his head gently enough, Dean't can't take him down fully and instead keeps his tongue working, growing ever more used to the feel of Lucifer between his lips. Sucking lightly between occasional pulses of his head, Dean quickens his pace, focusing fully on Lucifer's cock.
