I have not been with both, just candy. I suggested a personal trainer scenario where she had been training me and just had to take me to a hotel for a "workout".
Outfit was perfect, and she got into character, saying things like "I wanted you to bend me over the machine" and stuff. So she does play the role you ask her.
She also got serious plus points for role playing in comms but still giving me all the information I needed and asked for.
