Princess McKenzie wanted to test her slave. She wanted to have a slave who was hardy. So she made him lie down and she used her bare feet to trample his head. When she was done with his head, she trampled his neck and his shoulders as well as the rest of his body. She watched out for how he took the pain and what he did before she let him go.
