Captured by the Game 1/9

Captured by the Game
Rating/warnings: NC-17 for dirty deeds glancingly described. Sam/Dean. Impure wish-fulfillment.
Summary: AU. Azazel has given his favorite son a task: worm his way into the confidence of a hunter. It sounds simple, but Dean Winchester just might be more than Sam can handle.
Thanks: giandujakiss and coffeeandink, for kicks in the pants above and beyond the call of beta; Mary Ellen Curtin and cathexys for beta.
ETA: Full story at the AO3 if you want to read the whole thing at once.

( Father gave him the assignment just after his twenty-second birthday. )
