As you can see, she really likes to mishandle these male parts, to tie them up, slap and punch them like crazy. As she brutal punches the nuts, she just laughs when the slave is in pain. She leads him by the ball leash through the room, force him to pull them up with the leash between his teeth and kicks them ruthless, regardless they hurt more when tied up. She even make him beg to kick him harder in the balls.At the end she makes it very clear that these balls are her balls and she can do with them what ever she wants.
