Clover clamps hurt a lot! Polina did NOT like her previous encounter with these vicious things. We decided she needed some more training, so we told her to clamp herself again. She started sobbing immediately. We had to lock her in the heavy custom stocks to prevent her from removing the clamps. Ballgagged, Polina would have to wait quite a while before she would be allowed to take off her clamps. She cried and cried. poor Polina!!
