I'm a big fan of AMTDI and/or sex pollen fic, but what I'm looking for here is Crowley forcing Dean and Cas to have sex. Perhaps he's holding Sam hostage or has some other chip that will force them to do his bidding. Dean is surprised but resigned, hey, he's done worse, right? And Cas is horrified, because it is his secret, deepest desire.

Bonus points if Sam is forced to watch, and/or Crowley is super bossy and tells them exactly what to do.

Is there anything like this out there? Anyone? Bueller?
