Currently thinking of Dean Smith and Sam Wesson fuckin' nasty in the bathroom, and Dean asks Sam "hey, uh... can you do something kinda out there for me?"
And Sam's willing to do just about anything if Dean will keep hitting his prostate like that so he says "whaddaya want?"
"Can you pretend I'm your brother?" is mumbled out, but Sam understands just fine, and it turns him on even more.
"Fuck, yeah. Fuck me so good, big brother, love your dick so much."
And Dean gasps out "Oh, fuck, Sammy. Baby brother," and bites the back of Sam's neck as he comes.
(and somewhere in Heaven, Zachariah is slamming his head against a wall at the realization that even without knowing it's incest, the damn Winchesters made it incest)
