Hi, I read this fanfic a couple of years ago and I'd very much love to read it again.
It starts off with Sam and Dean giving each other the silent treatment and Sam angsting over how he's going to repair the damage between them, when Dean no longer trusts him. Sam tells Dean he'll do anything to repent for his betrayal (I think with Ruby). Dean makes Sam his slave and it turns from punishment into something very sexual. I think that Dean gave Sam a collar and tells him if he takes it off, this punishment is all over. Their first time is Dean bending Sam over a desk. Please tell me if you recognize this? It had a happy ending I think. If you have a link, please share? Or you can email it to me:
