Summary: Fill for the
spnkink_meme prompt: Dean is fifteen. Sam is twenty. Sam's obsessed with fucking Dean. So he starts drugging Dean at night when John's hunting, then strips sleeping!Dean down, sometimes fucking his ass, sometimes fucking his face (forcing the come down the still-sleeping Dean's throat), sometimes both in one night. Then he cleans up every trace, so there's no way for him to be caught. Bonus: what he's doing is slowly driving Dean crazy, because he knows there's something wrong, but can't find any proof of it or anyone to suspect, and to Sam that just makes it all the more fun.
Chapter summary: It's somehow more and less frustrating now that he's had Dean.
