I've tried this before but it's never taken off for some reason or another. PM me if interested do not post here.
The basic premise is that a Queen (You) has gotten a new slave girl from another kingdom, I did have a princess in mind for this role as it would cause quite a stir, but this can be discussed and changed to something else.
This slave girl will be reluctant and stubborn and will need to be put in her place quite often. (Taking a reluctant sub role)
I wouldn't mind this being a furry rp, or a human only one depending on your preferences.
