Most of the erotica I've posted is het, which is odd, since I ain't. However, I've written two fairly (in)decent yuri pieces.
Lulu Sutra: Lulu/Rikku. Lulu, underwhelmed by Rikku's louse of a boyfriend, offers to teach her what good sex should feel like. This one's got a little plot to set up the situation; the sex is in chapter 2.
Keraunophobia: Lulu/Rikku PWP. What happened that week Rikku camped out on the Thunder Plains trying to get over her fear of lightning?
