Crowley thinks the angel will need corrupting, and he's all prepared to show him all the depravity he's been witness to since he sold his soul. He has no idea what he's in for once he opens that door, but between the radio tower fucking, the bondage made from actual spider-webs while Castiel plays the spider, and the way Castiel yowls like a cat in heat loud enough to shatter all the glass in a fifteen mile radius, he's starting to wonder if he's out of his league. Crowley didn't raise himself to be a quitter, though, so he vows to find something that'll drive Castiel wild that neither of them have even imagined yet.
