Eclipse (Sterek)

Stiles was completely sure, without a single strand of doubt that Derek hated him. But that seemingly wasn't the case as one night Derek couldn't resist the urge to mate Stiles. But now after that one night something is off about Stiles, as he's become more and more distant from the alpha and is unexplainably going through one hell of a change.

(Not related to I only want you, it's a different fanfic that I felt the urge to write).
