Ran across a reclist (http://prosodi.livejournal.com/174201.html) by prosodi on my friendsfriends, whose username I vaguely recognize from Hornblower fandom, of "not my kink but these Sherlock ficwriters make it work" stories - from G to NC-17 and many of them quite fascinating character-insights into John and Sherlock.

Copperbadge Sherlock fic! Brewster hath a happy.
