Could it be her way of trying to force the end of your encounters whatever the reason may be?
I thought that at first, but she reaches out every time she tours nearby so wtf mind game is that so then I shifted to
In my opinion if it's been brought up already it's either that she conditioned herself to act this way with men she has sex with or clients in particular, or because she is trying to be forceful about it and this has become a power game to her. Some people really validate themselves through seduction.
Which is what I think too, now. I think this is a geniune thing that she enjoys doing, maybe a kink that she doesn't or can't share with others. Keep in mind I had at least 4 or 5 mostly-vanilla sessions with her before she started doing that and she was right into it and came harder than ever before so I just chalked it up to that. I've had quite a few providers share their personal kinks with me and I'm mostly game with all of them or we just don't do them if I'm uncomfortable and it's never been an issue so I think this thing, whatever it is, is just something that she really wants to do and maybe my pushback it is also part of the appeal (a CNC variation or something).
IDK and, honestly, I don't much care either. I am go-with-the-flow on almost all fronts and expanding my sexual self is actually something I really enjoy about seeing providers, but I have a few lines in the sand and that's one of them, so now I'm in ghost-mode.
