Hey! Some other good ones I know;http://www.gayspiralstories.comhttp://wesleybracken.tumblr.com
(Mostly Mind Control and Transformation)
Nifty is *the* online repository of gay erotica [just google 'nifty gay'] their sci-fi/fantasy has some decent stuff, though there's a lotta dross to search through, if you can specify what you're looking for I could reccommend a few?
The other I would say is metabods, a real gem of a site for all sorts of alt bara <3
