1: A Fistful of Sand Book 1 by DoktorGostel Another classic I've read several times. Not only is the sex described really well, but the descriptions of the characters are superb, and the characters themselves are enjoyable. As with most of these stories, I'm not crazy about the main character, but the ladies are - *chef's kiss*
2: Mom Tries Belly Dancing by alwayswantedto The slow build-up and burn are why I've read this. Coupled with the forbidden subject matter, and this story haunts. Unfortunately, it falls a little flat near the end for some reason. I feel like adding the aunt took away from it for some reason.
3: Alan by Julian Coreto An oldie but a goodie. I enjoy the maledom factor with the girl who's given him a hard time. There's also the taboo teacher factor. The sex is a little less descriptive than I'd like, but I enjoy the development of the abilities and the mystery of the ring. I especially love the little episode with the British girl.
