When this mistress was misled by this loser, she had to torture and dominate this guy which she did without thinking twice about it. She hated being misled and that is why she had to do what she did. The mistress could not let the slave do what he had done to others so she trampled him with her sneakers and she made sure it was painful enough to be a deterrent.
Mistress Zephy knew how proud this guy was and she had to take his pride down a notch. She did it with her feet as she trampled him. She made fun of him as she trampled him and he nearly cried. He was, however, lucky that she did not choose to use her high heels to trample him and instead she used her bare feet. He would have been in even more pain.
