This mistress was pissed off by this guy and she did not want to let the guy think that he could mess with her and get away with it. So she had to punish him and she did so using her converse femdom. It was painful and it was humiliating but there was nothing he could have done about it other than to endure it and beg her for mercy.
Mistress Chayness wanted to trample her ex and she did it with her sneakers. She did it with her dirty converse sneakers and she had a great time at the expense of the guy. The guy cried and wished that the mistress had not done so but it was too late and he had to endure what she chose to do to him. There was no alternative for him and he had to understand that.
This mistress felt that the best way for her to do what she wanted was to make sure that she dominated as well as humiliated this loser who was her ex. She had tried to make him learn that she did not want anything to do with him but he did not seem to get the message so she had to do it in a way that he would never forget. That is why she chose to make him lick her sneakers and do other humiliating things.
