Rating: R (warnings for bloodplay and sexual content)
Word Count: 1,756
Summary: early-mid Season 6: Castiel needs a favor from Sam - namely, his blood. Surprisingly, Sam is not that bothered, but then again he's not quite himself these days. RoboSam/Cas (can we call this Robosassy? :D? OH MY GOD I CAN'T BELIEVE I WROTE SOMETHING THIS CREEPY)
He presses a knife, gleaming and pentagram-engraved, into Castiel's hand. "Now cut me."
