"Dean..." Castiel looks unsure. Dean's words start to break through his resolve and he's not entirely sure what to do with that, because he does want Dean and it's not just what he is that's making him want Dean so much.

He swallows. "I don't want to take advantage of you."

Where he'd had the strength to say no before, now he finds his skin calling for Dean to touch him. Every part of him is screaming for it and the heat pooling in his stomach is almost unbearable.

It keeps getting worse. No matter what, it keeps getting worse and he needs something, because it feels like he's dying.
