Hey,

I remember reading this story where Sam was a hooker while he was at Stanford. Bobby found out and made Sam promise that he wouldn't do that anymore. Later, once Sam is back hunting with Dean something happens and Sam starts hooking again. Dean finds out and talks to Bobby about it and Bobby couldn't believe that Sam had broken his promise. I think it ends up as Wincest, but I'm not 100% sure. Unfortunately that's all I remember. Any help would be greatly appreciated!

Thanks!
