This slave was being punished for not following instructions. The mistress made him lick her shoes and then smell her stinky socks and lick her sweaty socks and he had no option but to do as the mistress wanted
This hot blonde babe mistress Cathy teaches her slave how to behave as she forces him to lick off her boots and he does not do it right for her and she slaps his face over and over again until she leaves a bright red spot on his face. Once he learns his lesson she forces him to finish licking her high heel boots clean with his tongue until she is happy.
Cathy is a boss in her business. There are days where there is not much to do and she needs to spice up the office area to keep her motivated. Thankfully one of her co-workers is down with face trampling. In her black high heels Cathy is trampling over this woman's face making her lick the soles and then she takes off the heels and makes her sniff her slightly sweaty feet.
