I really enjoyed "Blackmailed Slaves for Life" though it was not finished and "Tri-Slave Tournament" though it's already been mentioned but it was a really good one. "The Facility" is pretty interesting as well, I enjoyed reading it.

And of course my own story I'm a little bit fond of though I'm kinda biased...(link in my signature :P).

There's some good stories out there other than what I mentioned just can't pull many names out of the top of my head.
