Lady Scarlet wanted to make this vile old man learn a lesson he would never forget. That is why she opted to use her muddy shoes to do it. The poor guy had thought that his age would be insurance against him being dominated. But the mistress did not care and instead she kicked him on the face and had him lick the muddy shoes until they were clean.
Lady Scarlet and her friends realized that they had been harboring a loudmouth and they had to punish him. He was their slave but he was also a loudmouth, something that the mistresses did not want to tolerate. So they punished him by making him endure trampling and humiliation using muddy feet. He cried and promised never to do it again and they believed him and gave him another chance.
Lady Scarlet noticed that her agent was not as enthusiastic in getting her gigs as he was to his other clients and she was so pissed off at him because she felt he was sabotaging her career.

Lady Scarlet wanted her muddy shoes to be licked clean by her slave because he was in charge of cleaning them but he had not done it.

Lady Scarlet and lady Selly did not like how this guy tried to make them conform to his standards yet he was merely their neighbor. They told him to mind his business but he did not seem like he wanted to. So the mistresses saw it fit to torture him a little and they used their muddy boots to do it. He had to lick them clean and he never bothered them again.
Lady Scarlet was dirt broke and she knew that if she showed any weakness, her landlord would chase him out of her house like a dog. So she told him that he had been looking at her suggestively and he had violated her. As he protested, she used her muddy shoes to scare him as he was made to lick them. Then she told him that as a result, she would not pay that month's rent. He did not object.
This business executive was used to taking things for granted and he did not treat customers the right way. But lady Scarlet was not one of them. She followed him back to his office and she used her muddy shoes to trample and dominate him. The mistress did this after she had stripped him naked. She also made sure that he licked her feet before she was done with him.
