I am an amateur author that has been writing non-erotic stories for quite some time now, and have just recently experimented with erotica. Hopefully my experience in other genres has helped to improve the quality of my erotic stories.
I write character-driven stories, because my philosophy is that if you care about the characters you will enjoy the story much more. My stories are mainly light-hearted, and portray sex, even forbidden sex, in a positive light. My favorite fetish is incest, and this features prominently in almost all of my works. There are often very young characters involved. I usually set a minimum age of thirteen, but I may occasionally go lower if I need a character of a certain emotional maturity level.
