Mistress Sophie loves getting a foot lick and a foot rub. Today she was considerate to her foot slave as she did not want him to do that on rough feet. That is why she chose to make her slave do it on clean and well scrubbed feet. So she scrubbed them and when she was done doing it, she had him lick her feet, rub them and also suck her toes.
Mistress Sophie had smelly and dirty feet and she used them to dominate this guy. She felt that he needed to be taught a lesson and she made sure that he licked her feet. He tried to refuse but she made it clear that if he did, he would have himself to blame for whatever would happen to him. He never messed up again for fear of what she would do to him.
Mistress Sophie does not like being ignored and when this guy did it, he had to be punished. The mistress punished him cruelly for doing that and she ensured that he licked her feet as well as did other crazy things that he had never imagined she could make him do. When she had enough of it, she sent him away and he had no choice but to do as told.
Mistress SophieKnight wanted to set up her slave for domination and she had an easy time doing it as she was a pro. She teased her slave but acted as if she was doing it for herself. And when he looked, like she knew he would, she acted pissed and accused him of disrespect. She then punished him for what he had done and that is how she foot trampled and humiliated him for fun.
