I’m always keen on interesting CBT shots, but it’s the expression on the ladies face that really makes this image. I like to think he has just moaned loudly and that’s her reaction to it. Half amused at his cries and half quizzical about the level of pain. She’s pondering does it really hurt or is he exaggerating? Should she should give it another twist to see if she can get an even better sound out of him?
This is from the Divine Bitches site. I’m afraid I don’t know the name of the lovely lady in the glasses. I found it on the Alternative Femdom tumblr.
