Madame Marissa is a cruel mistress and she loves it. She likes inflicting pain on her slaves and she does it for fun. She is one of the few mistresses who do not wait for slaves to mess up in order to punish them. She has a slave because she wants to have fun at his expense and today that meant trampling him and jumping on him and making him scream a bit.
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.
