Madame Marissa realized that she had a slow slave. He was new and she was getting to know him better and she was not impressed with him at all. So she felt that the best thing for him to do was to trample and dominate him and she used her riding boots. He was in pain but he learned to change and be sharper than he was which pissed her.
Madame Marissa wanted to humiliate this loser but she wanted to make sure that it was a punishment that was worth it. So she tried boot punishment as she had never tried it before. The mistress used dirty and muddy boots to punish him. She made sure that he licked them until they were very clean before she let him go. He never wronged her again as he knew what she could do.
These mistresses did not like how their husbands liked to do things together in order to try to escape accountability. They wanted to tame them and turn them into obedient husbands. So they chose to punish them together. The mistresses used their boots to trample their naked husbands and made them feel pain they had never felt before. It was also humiliating as they were fully naked and could not do
These mistresses wanted to show this guy what the consequences for his actions were. The mistresses had caught him trying to steal from them and he had to face the consequences. He was shocked at what they did. The mistresses used their riding boots and whips to torture him after they had stripped him naked. He could not believe that those cruel things were happening to him but he could not blame anyone.
This mistress is petty and when someone does anything as small as even looking at her and she interprets it as being looked at in a funny manner, she gets pissed and she can torture that person badly. That is what she did to this guy for looking at her in a way she perceived to be funny. She then used her boots to torture him by riding him like a horse and stomping on him.
