Hi people! 
This community? Is great!
Now there was this fic that I read not so while ago. From what I remember- Sam and Dean are sitting at some bar and in the end Sam hooks up with some guy. Next day Dean keep bugging Sam how its like to be with guy until Sam hmm shows him. And I think in the end there was this scene in the shower when Dean says that he don`t want to talk about it (wincest) but would like to keep doing it.
So anybody knows what I`m talking about? 
  
ETA: Found! Thanks!
