Madame Marissa caught her boyfriend cheating and she did not like it. She had to make sure that he learned his lesson the hard way. The mistress had to make sure he would never even think about it let alone do it again. So she used her muddy shoes to trample, stomp as well as crush him. He was in the pain of his life and he regretted what he had done.
This loser needed to be punished for being negative. He was a negative influence and he liked to distract and also discourage people. She did not want such a person near her and she tortured him with her muddy shoes so that he learned a lesson and stopped that bad behavior. So she used muddy shoes to ballbust him and he cried and begged her to stop telling her he had learned his lesson.
Madame Marissa did not like how proud this girl was. She tried her best to avoid the girl but today their paths crossed and she could not stand how proud she was. The mistress had to punish her and take her pride down a notch. The mistress forced the girl to lick the soles of her muddy shoes. It was not optional and the girl for the first time got the humiliations he deserved.
Madame Marissa purposefully made her feet muddy. The mistress did this so that she could use her feet to dominate and to degrade her slave for messing up. Once her feet were sufficiently muddy, she summoned the slave and she forced him to lick her feet. He licked them as well as she wanted and within a few minutes, her feet were as clean as she wanted them to be.
