I haven't come across any that do this. I've been let down with some sessions where the domme seemed to not want to do strapon play and claimed I wasn't properly prepared, despite doing it the same way every time and getting many compliments on how I did it after strapon play. Same scenario though... they basically start with a dildo not on a harness and then make that claim. It's only been two, both younger types.

This is probably the biggest dissapointment to me. I've had a newer domme who decided to whip me and use a spike rolling wheel device in a chopping manner on me and cause blood, but other than that, I've found dommes respect limits and don't introduce trickery.
