Mistress Maryan did not want a slave who masturbated and that is why she had to punish this guy for doing it. He had to know she would not condone it so she used her jeans to facesit on him. He was in pain as the mistress crushed his head and his body. He tried to cry but she did not care about what he did. All she was interested in was to punish him and she did it.
Mistress Maryan was so disappointed and pissed at what her slave had done to the point that she had to do something crazy. It was something she had never done before in her life. The mistress made sure that the guy licked her dirty asshole until it was clean before she let him go and warned him never to repeat what he had done. He got the message loud and clear.
