Mistress BlackDiamoond always knew what to do to her slaves when she wanted them to do something for her. She wanted so extreme that this slave was afraid to do it. It was risky and he had never attempted something like it before. So she made him do it by trampling him using her high heels and making the actual thing loo worse than her trampling so that he could choose to go.
Vanessa loves to dance. She loves it so much that she wanted to try dancing on a different surface. She thought about it and realized she had never danced on a human body before. So she called her slave and made him lie down. She was wearing her shoes as she got on top of him and started dancing on him. It was painful to him but it was fun to her.
