This was short, hot, and fucking awesome.
Stiles is trying to make money to fix his jeep, so he gets the brilliant idea for he and Derek to have sex for money. Only, of course, Derek is totally in love with Stiles, doesn't want to fuck for money, but doesn't want anyone ELSE to fuck Stiles for money, and also wants to take whatever chance he has to be with Stiles.
Enter super hot sex scene that becomes more than they ever thought it would be, denial of feelings, a fight, and then finally, admitting of feelings, and love!
