Why bother exercising when one can just work up a sweat beating on slaves? Varla enjoys getting her "slavercise." Here she decides to work out by using a slave's balls as a speed bag. She has just finished kicking his balls all over the room and they are big and swollen - practically melon sized. They make for a perfect speed bag. Varla has put on her MMA gloves for the occasion. The slave screams as she punches his balls over and over, causing them to swing back and forth to her amusement.
