This guy was caught masturbating and this mistress wanted to teach him to know how to seduce girls instead of waxing his carrot. So she got him naked and she kicked him in the balls. She did it hard and repeatedly and she made sure he learned the lesson she wanted to teach him. She also used her hands to crush his balls and not just with kicks to the nuts.
This mistress likes to punish slaves for sport. She enjoys torturing them and is always looking for reasons to punish them. When she found this slave had not done what she had told him to do, she humiliated and tortured him using her pumps. She kicked him hard in the balls using her pumps before she used her bare feet to crush his balls. He was in pain but she did not care.
Madame Marissa wanted to make her slave feel some pain so she started with a balloon between her ass and his balls. It was not as painful and he did not complain. But what he did not know was that she was preparing him to be content before doing what she wanted. Once he had relaxed, she removed the balloon and she fell on his balls with her ass and he screamed in pain.
