Among SM lovers very well known despite the fact that it is oftenly explained wrong. It is often mentions the beating with instruments and that is not correct. The translation out of the English dictionary is: the beating of buttocks with bare hands. But you can also wear gloves of course.
Again, an illigal fact, but not in my studio mind you! On the contrary, I can enormously enjoy the sound my flat hand makes on your behind. I love those red slave buttocks.
Will you be on my lap and leave with the print of my hand as a souvenir?
