Im looking for a fiction that starts with John, Sam, Dean and Bobby in a bar. Someone makes a bet that Dean can't get some girl's attentions if he dances. One of the group, Bobby I think says something like "Have you seen Dean dance? " Turns out that Dean is a really sexy dancer and gets the girl and John calls him a slut. A demon (Azazael?) who knew Mary becomes fascinated with Dean and everyone has to stay with him at all times so the demon doesn't steal him. It was a WIP , AU I think because Sam and John seem unaware that Dean can dance but Bobby knows so maybe John lives after IMTOD. It was good but left off at a cliffhanger. I'm hoping they finished it.
