Princess Kate is into slave humiliation and she likes using her feet to do it. She likes to do anything to her feet as long as her feet become dirty and smelly. With her feet in that state, she then makes her slave lick her feet. She sometimes shoves her feet into his mouth and makes him suck her toes. Luckily for him, today she was just interested in him smelling her shoes and feet.
When Sharon comes home from work, her feet are normally hurting from being on them all day. She takes off her shoes to reveal dirty socks to her slave. She makes her slave smell her sweaty shoes and puts her dirty socks on his face. She slowly takes her socks off and puts them in her slave's face. As soon as she has the strength, she tells her slave to lick and suck the cramps from her feet.
