I was cleaning out old files and came across an old favorite: Stuart Finkelstein's Blackmailing The Queen. It was posted here in 1999, but I read it long before I found SOL. https://storiesonline.net/s/33098/blackmailing-the-queen
Anyway, it was posted so long ago that many, if most of you, may not have found it. It is pure hetero sexual fantasy with some girl-bi thrown in. Fun story along with the sex.
Highly recommended.
