Note from me: Today I reblogged a gifset about Sam & Dean falling in love, later finding out they're brothers. I wanted to read a fic about it, novel-length. Yes, please and thank you. I usually don't even read wincest fics, I'm all about the J2 love. But damn this sounded so promising.
Then the wonderful Jieve rec'ed me 'The Psychology of Genetic Sexual Attraction' and I started reading it just half an hour later - at the office. Screw responsibilities, I just had to read it. The summary promised me that the story would be exactly what I was asking for. And since I'm rec'ing you guys this fic it definitely is one great story!
