"Susan and Becky" by Jonathan Dzoba. This story is written in the format of letters from Susan, who is a teenager at an all-girls band camp, to her boyfriend. After a brief build-up in the first three letters, the final two letters describe the girl's sexual intimacy with her female roommate. I found the descriptions to be wonderfully erotic. The notion that the story is being told in letters to her boyfriend adds a bit of titillation to the story. What I don't understand is how somebody named Jonathan Dzoba could understand so thoroughly the emerging sexual feelings of a blossoming young woman. Excellent story.
