Mistress Anni has sexy feet and sexy legs. And she used both of them as bait to get this guy to do what she wanted. The mistress was bored and for lack of a better thing to do, she had a great time torturing the guy with her sexy legs before she left him high and dry. He thought she was interested in her but he was shocked she was just using him.
Mistress Anni likes decent people. When she realized that this guy was not, she felt obligated to do something about it. She had to be the one to teach him how to behave and how to do things. So the mistress used her sneakers to humiliate him and the guy learned his lesson in a humiliating way. He never tried that nonsense again as he knew he would be on the losing end.
