When the mistress took the young Betty to the gym for a workout, poor Betty was not prepared for such a surprise. She had probably expected to participate in the training and to do a lot of sweaty sports. But Bella had something completely different in mind. She decides to use the gym for her perverse fantasies. She wants to show it to Betty today and humiliate her. From whip blows, spanking, controlled orgasms, perverse masturbation, bondage to fitness equipment to self-realization to fitness equipment, nothing escapes Bella's perverse and diabolical spirit. She will surely let the pulse of her Betty shoot up!
