Good morning...I was wondering if you guys could help me find a fic that I must have forgotten to save in my memories.

It is Wee!cest, and all I really remember is that Dean eventually comes to believe that Sam only started up the relationship with him because he wants John to find out. Sort of the ultimate "screw you". He flips, sends Sam packing, and then when Sam comes back to help him find their Dad, Sam confesses that he wasn't so careless because he wanted John to find out, but because he was so in love with Dean he couldn't see straight.

Any help you could give me finding this would be lovely! Thank you!
