Mistress Barbara felt like this guy needed to be punished so she did what she felt was the most appropriate way to deal with him. The guy was shocked to learn that the mistress was intending to facesit on him and to choke him. He cried and begged her not to do it but she laughed at him and she did it. She even went ahead to fart on him.
Mistress Barbara was disappointed in the kind of oral sex this guy gave her. She felt that she had to make him realize he was not as good at it as he thought he was. So she trampled him with her bare feet and he was lucky that that was the only thing she felt like doing to him. She let him go and improve his skills after that trampling.
