This mistress likes to trample and today she wanted to do it using her sneakers. She was punishing her slave and she wanted it to be as painful as it could be. She made her slave lie down and she used her sneakers to brutally crush him. She enjoyed the sound of him in pain and gave him a warning that there was more to come if he did not mend his ways.
Madame Marissa wanted to punish her slave for stealing her stuff. He had stolen small stuff but she wanted to show him that it was still not ok. So she used her sneakers to trample him as punishment. Besides trampling him and jumping on him, she also made him smell and lick her smelly shoes and sweaty socks. By the time she was done with him, she knew he would never steal again.
