7: The Grim Reaper by rlfj rlfj has written several great stories, including A Fresh Start and The Power (closest to my own work). This is the latest and as of yet still unfinished one, but they're all worth reading...
8: Growing Up A Master by MWTB Re-reading this, it's clear in hindsight how much it influenced The Master Downstairs. Well written and worth reading.
9: Jason's Power by E. Z. Riter Hypnosis, but effectively MC. A story that starts out on one birthday and ends on another. He's trying to do his best to help and not hurt people.
10: Lost Toys by Redsliver starts slow, but quickly improves. He tries to do things as best as he can, and the different female voices are great.
11: A Master's Ring by ElSol A long complex story, which has gone through several iterations. It's a powerful read and you'll remember the characters long after finishing it.
12: Masters by 0xy M0r0n Nicely written and ended up somewhere I didn't quite expect.
13: Mural by aroslav A three part longer story, the characters feel like real people even though they are in a pretty rare type of arrangement. They each struggle and fail and try again. Great long read with fantastic sex scenes throughout .
14: My Inheritance by E. Z. Riter I read this a long time ago, and rereading it now, I see a lot of parallels. Great story, responsible protagonist, quotes Acton. What else could you want?
15: My Journey - Book 1: Collars by Xalir Well written take in the super genius builds a harem genre. The ending is a bit too much of the "everyone betrays me" meme, but it comes back together in book 2.
16: Sensualist II by Paris Waterman Another author who's written a lot of different stories, but told with the same grace. This is the latest, but you should read anything written by them.
