Madame Marissa had a nosy neighbor who needed to be dominated and punished. So she humiliated him with her high heel boots by hand trampling him and causing him to feel a lot of pain in the process. He was shocked that she could be so cruel but he had brought it on himself and she did not care about what he felt. He had to unlearn the nonsense he had learned.
Mistress Tiffany had a slave who she felt needed to be punished because he was not working as hard as he needed to. The mistress had given him time to change and do things the way he was expected to but he did not. So she had to step in and make him do things how they were meant to be done. She hand trampled him using her dirty gumboots and he learned his lesson.
Lady Sandy was shocked to see this guy projecting strength she could tell he did not have.
