Madame Marissa wanted to deal with this slave as early as she could so that he would stop being a nuisance to her. The mistress went ahead to crush him with her high heels and hand smother him. She did it while he was fairly new so that he would learn from early on that he had to be careful in what he did and what he said to her.
Madame Marissa was not pleased with what she had learned about her slave. She learned that he was a liar and a cheat, none of which was a good thing. She had to save him from himself and she used her boots to do it. She trampled his hands as well as his fingers and it was painful. He cried and promised never to lie or cheat again before she forgave him.
Madame Marissa wore her winter boots and she used them to crush the hands and fingers of her lazy slave. She was not happy with how he did his chores and she had to get him to change or send him away. She chose to give it one last try before chasing him away. She crushed his hands and especially his fingers. He cried and groaned in pain and she knew it had gotten to him. He changed.
