I’ve had a few sessions where the Domme has taken her top off unsolicited by me. It’s always a bit unexpected, but has always been fun. I think for me it would totally mess up the power dynamic if I said “I’ll take x punishment for you to do y reward”. But if you flipped it a bit though it could be quite fun. I love ballbusting sessions and I could see a scenario where the Domme says something like “if you can take 3 kicks without falling or making a noise, I’ll take my top off (or whatever reward). I’ve had Dommes do the reverse of this (the stick vs the carrot) so basically you did x wrong, so I’m giving you y punishment. Which has always felt a little forced to me tbh, so reversing it seems like it could be interesting.
