I have started to read some erotica books but am having a hard time finding what I am looking for. A few have been what I'm looking for but then most have not. I am looking for books dealing with masters and slaves but not on other planets or dealing with other species (I've seen several of those). I am also not looking for one that is constant humiliation and just torture. I don't necessarily mind reading those but it's not what I'm looking for, I'm looking for at least a relationship of some type (not necessarily love though)

I have read these and found the writing well-done and the stories to be what I really enjoyed if this helps:

Slave (Finding Anna) - Sherri Hayes (this just came out)
Comfort Food - Kitty Thomas
Tender Mercies - Kitty Thomas

Does anyone have any suggestions? .
