When she comes home from a night of hanging out and drinking, she hates the way her feet smell. She calls her faithful slave to her and nods towards her feet. He immediately gets down on all fours to suck the tip of her shoe. She gives him permission to take her shoe off and suck the sweat and stink off the bottom of her nylons. She enjoyed watching him and feeling his tongue. When he finishes, he has to service her friend.
Kathi has always been the superior of those two sisters. She was also even stronger than Demi. So she made her younger sister obey and worship her. She forced her to give her money and she made her do disgusting and humiliating things like making her kiss her stinky smelly feet.
