Stiles runs away during his first heat, right into the waiting and ambiguously scary arms of the Alpha's nephew, Derek Hale. He doesn't have any choice except to submit, but along the way, he digs up a mystery that threatens his family and even the town's safety.

AU. Alphas are like royalty and are offered their choice of any age eighteen-and-up virgin Omega for each year's heat season, as a 'thank-you' to all they've done for their compounds throughout the year. Derek is an Alpha and...yeah, Stiles. Stiles is an Omega. And still a virgin. In every way. And he's just turned eighteen. This...is not his day.

The drug is called heatwave. It supposedly emulates werewolf heats on humans. And yes, Stiles is stupid enough to take it on a dare.
