After reading what the author calls "the gayest explicit gen ever":
trusting who we are by
obstinatrix, I was reminded of a rec list I'd seen in the past year of what the poster called "extreme gen" for want of a better term. Basically fic that focuses on Sam and Dean's relationship as codependent and intimate and protective all those delicious things taken to the extreme - but it's Gen.
I'd love to track down that rec list - or any fics you think fit the bill.
