Looking for a fic where John finds Dean in a restroom after being gang raped by a group of bikers.
I read this fic a couple of years ago but I can't find it for the life of me. Basically, John and Dean are in a bar hanging out, planning a hunt. At some point, Dean has to go to the restroom and John waits for him but Dean never comes back.
John starts to get worried when he suddenly overhears a group of bikers laughing and jeering. It soon becomes clear that they're talking about having sex with Dean. One of them says that he prefers it when his "partners" cry and put up a fight, rather than silently taking it like Dean (or something along those lines). I don't remember what happens next, but at some point, John finds Dean in the restroom, curled on the floor and covered in blood, vomit, and piss. Dean is on the verge of passing out, but he tries to leave and tells John that he will never see him again if he wants. Dean thinks that John is disappointed and disgusted by what happened to him, but John is actually horrified. He doesn't want to see his son hurt and vows to protect him.
It was a somewhat short fic. I think it was called "The Devil Smiling with Delight" or something like that. Does anyone remember it? I've been searching for hours.
