Goddess Katrina had a business partner who was not reliable at all and she was fed up with him to the extent that she had to find a way to deal with him. That is why the mistress had to ensure that the poor guy learned his lesson and that he never messed up again. He was trampled and forced to lick her smelly feet and that did the trick.
Goddess Katrina had caught her slave checking her out and she felt that she could show him her hot ass for a little bit. She was in a naughty mood so she had him watch as she played with her ass and her pussy then she made him jerk off as she could not fuck him however horny she was. He was ok with jerking off to her instructions and it was a lot of fun.
Goddess Katrina was out to humiliate for fun. No one had messed with her and she was not angry or disappointed. All she wanted was to have fun with her feet and so she turned to this guy and she had him lick her feet and smell her socks. He was her foot slave for the day and when she had had her fun, she let him go and thanked him for the fun.
