Lady Soles had smelly feet and she wanted to use them to dominate this guy. He was her neighbor and he was a pain in the ass. That is why she needed him to be punished for the things that he did. So she had to do whatever was in her power to torture him and have him lick her stinky feet. She also crushed his balls a little before she was done with him.
When this mistress set out to pass a message, she chose to use her foot domination fetish to do it. She knew that she had to use that to make this guy not only get humiliated, but he also had to feel pain. That is why she trampled and crushed his balls and his dick before she asked him to lick her feet as well as suck her toes. He did it all.
