What Mistress Ayn said.

Most people who go into a femdom session aren't actually looking for a Mistress who dirty talks about how she's going to be such a good service top and make her sub so happy. I've had many requests in my long career and "talk about how you're just here to cater to my desires" is one I've never gotten. Nor would I take it! As far as I'm concerned that would be a sub session, which is not something I do. I'm a dominant, I like dominating, pleasing myself and pleasing my submissive are not actually remotely mutually exclusive.
