Fic search: Wincest with dark!demon Dean
I hoping someone can help me find this fic.
I read it a long time ago, but I guess I forgot to bookmark it and it's been driving me crazy trying to find it.
Basically it was a pretty dark demon!dean/Sam fic. I don't remember the exact details, but it involved Dean finding Sam eight years (or something to that effect), after he went to hell. Only this time he's a demon. Sam is at first wary of him, but goes along with it.
Two scenes I remember:
1. Sam walks into Dean having sex with a girl and is horrified, when he realises that she's engaged.
2. Sam walks into Dean with a girl again, only this time she's tied up and he (Dean), makes the girl come in front of Sam. He uses the situation to manipulate Sam into having sex with him.
I'm pretty sure the fic ends with Sam and Dean being in a relationship, with Dean having a really dark, dominant role over Sam.
Sorry if this is too vague, but I'm really hoping that the details I've given rings a bell to anyone.
Thank you!
