Madame Marissa was tired of trampling her slaves indoors so she took one of her slaves outdoors and trampled him there. She did it in the open and did not seem bothered about who would see her. She just wanted to trample her slave and humiliate him and that is what she did out in the open. She trampled him using her muddy boots and by the time she was done, he was all brown from the mud.
Mistress Gaia and her friend wanted to test how much pain this guy could handle. They used their high heels to trample him as well as crush him to find out and they were impressed with the kind of pain he could handle. He did his best against the worst things they did to him and when he could not take it any more, they had nothing but respect for him.
