The women in my story will have to adapt. With time she will grow accustom to her new situation. That doesn't mean she'll be happy about it. Her intellect won't deteriorate (at least not very much), and she will never reach a point where all her thoughts revolve around pleasing mistress. I'm thinking about having her eventually encounter another human who isn't enslaved, and speaks English. Which will bring back all the humiliation of being naked and on a leash, after she had become confortable with it.
