Madame Marissa wanted to try slap fetish on her slave but since she was a fair mistress, she did not want to do it when he did not deserve the slaps. So she waited until he had messed with her before she slapped the shit out of him. The mistress enjoyed it and she forgot why she was doing it and went on slapping the guy until he peed his pants.
Madame Marissa is one of those mistresses who punish the part of the body she believes has made a mistake. When she learned what her slave had done, she blamed his hands. So she wore her boots and she used them to crush his hands. She crushed his hands and his fingers. She stomped on them and she jumped on them till he cried like a little baby and begged for mercy. She also slapped him.
