1: The Invention by Dark Paladin Awesome mind control story. It has one of the best threesome scene between the main character and two Christian sisters. I loved it. Very hot.
2: The Invention II: Touch of Lust by Dark Paladin Awesome sequel to The Invention. Although not complete, and I'm not sure if the author has abandoned it or not. Its been quite a while since the last chapter was posted, but still great.
4: Welcome to Summer Camp by Nick Scipio This is probably on everyone's favorite list, but I thought I'd add it to mine anyway. Book 2 was pretty awesome too, although the story seemed to be shifting focus from what I originally liked about it. Book 3 was so-so. The author is working on Summer Camp Book 4 now. But Book 1-Susan is an excellent read.
