I saw this on tumblr:

and now I want a fic like that! So are there any fics out there in which Dean finds out Sam has cheated on him after he comes back from hell instead of the whole ruby/demon blood issues? Even if it doesn't replace the ruby/demon blood, I'd still want to read some cheating fic so long as it's while Dean is in hell? Please only happy endings? Sad endings are too... well, sad.

Thank you!
