This guy was too timid according to mistress Vee and that had to be sorted out. The mistress chose to make the guy learn his lesson and do things her way. That is why she opted to facesit him and choke him in the process. He cried and tried to beg for mercy but she was not interested in listening to anything he had to say. He had to get the full dose of the punishment so that he stopped being timid.
