Teen Wolf AU: Derek and Stiles are supposed to go undercover as a couple. The only problem? They hate each other. Stiles thinks he has the pretending part down, but Derek clearly hasn’t. Cue lots of practice making eyes at each other, and practice kissing, which then leads to pretend making eyes at each other and pretend kissing on the job, which totally doesn’t lead to real making eyes at each other and pining and kissing. Nope, not a chance.
