Sell Your Body to the Night

This fic had me hooked from beginning to end, despite the excessive length. It could do with some editing to cut it down a bit, and some scenes seemed out of place (fisting and golden shower - didn't seem like the right build-up to either of these, more like they were thrown in just for the hell of it), though the golden shower made slightly more sense after more was revealed about Derek and where Stiles fit in his life. Other than those things, their relationship had a nice build-up, and I liked watching their struggle to keep things professional when clearly their feelings for each other were anything but.

What really hit me in the gut was finding out Stiles' reason for running away, then discovering that it was all for nothing because his dad hadn't died. All that hooking for nothing. Ugh, I felt his shock and helpless anger over that realization. That would cause some major mental and emotional trauma if I were in that situation. But hey, he did get Derek, so that's something.
