Madame Marissa trusted her slave to handle a crucial task for her but he disappointed her. She could not believe that he had lied to her that he was able to do it and that he had disappointed her that much. She had to teach him a lesson and she did cruelly. She used her sneakers to trample on him. She did not spare his face or even his balls.
Princess Serena knows how to humiliate a slave. But today she was doing it because she wanted to and not because he had messed up or pissed her. It had been long since she had done it and she missed it. So she wore her sneakers and used them to trample her slave and jump on his body. She stomped him for fun but was careful not to make it too painful.
