Mistress Ayn has a slave wearing a zentai full body suit. She has cut out a whole in the suit for his cock and balls to hang out, giving her a great target for beating. She uses a riding crop, small rubber flogger, and of course, her hands to beat the hell out of his cock and balls. The slave maintains an erection thru out the entire punishment, probably because of the fact that Mistress Ayn was sitting on his face the whole time.
