There's about half a minute in which there are nothing but deep, slow breaths coming from the angel, face tucked out of sight in the crook of Crowley's neck. He hadn't expected it to be quite so intense, all his desire suddenly focused on a single region of his body, one that hadn't existed mere moments before.

It feels so good, but it aches, too, like whatever he's experiencing is only the tip (ha) of the iceberg, and he needs more of it.

Eventually, he carefully lifts his upper half to look at Crowley, his eyes bright and his fluffy curls matted down with a bit of sweat. "Goodness," he breathes. "How do humans go about like this without exploding?" He feels Crowley beneath him and flushes. "How do you not explode? Especially in those trousers of yours."
