Mistress Sandy's trampling skills were getting a bit rusty. So she was out to refresh her skills. So she got a slave and went about clinically trampling, punishing, humiliating and dominating him. She made sure that he was topless and then got on top of him with her high heels. When it got unbearable for him, she decided to trample him without heels. So she sat on him and then trampled on his neck and face until she was sure that she still had her skills.
