Madame Marissa forced her slave to lick her boots. He had to do it because he had not followed the instructions she had given him earlier. He had nodded his head and she thought he had understood her but it seems like he had not. So she made him lick her feet and her boots before she used the same boots to trample him and make him learn his lesson.
Miss Diana felt like punishing her slave and she did not need a reason to do it like other mistresses do with their slaves. She went and found her slave in the kitchen and she used her boots to trample him. She kicked him and brutally dominated and tortured him. She kicked him in the face and made sure he was in a lot of pain before she let him go.
