"Metari Nights" by Mary Anne Mohanraj (mohanraj@mills.edu). Shalini has been sold as a slave/courtesan into the House of Leata. Unlike most of the sex slaves on this newsgroup, Shalini longs to be free; and she theorizes that the best way to gain her freedom is by becoming an extremely adept courtesan. Her sexual skills lead her into the arms of a magician who gains for her a dangerous opportunity to break away from her slavery. You can read the rest of the story for yourself.
With its vague setting in the mideast or the orient, this story reads like a sexy tale from "1001 Arabian Nights." In an epilog the author states that this is a cannibalized extract from a novel-in-progress. In spite of some rough edges - and unexpectedly bad grammar and style in Chapter 8 - this is an excellent story that combines adventure and romance.
