Lady Stefanie wanted to dominate this slave and she did it because she found out that he was reckless. She had to trample the shit out of him and she did this with her high heels so that it was more painful. He was tied down and she knew he would not try to fight back or piss her off. It was fun as she did whatever she wanted to him.
