Lady Cathy climbs on top of the restaurant's toilet and strip her dirty feet of her socks so they can air out. The coolness from the floor feels good against her bare feet. Her toes wiggle around since they were so scrunched in the heels that she was wearing. Now she would be happy if someone with a hot mouth could suck them.
Lady Cathy is in the bathroom rubbing her shoes all over the toilet when she commands you her shoe slave to worship her dirty shoes, she shoves her shoes in your face for you to smell and then begin licking her dirty soles clean humiliating you as she smiles at your suffering. This foot femdom wants her shoes licked clean and doesn't care if it hurts her slave at all.
Mistress Cathy took you into a toilet stall where she shows you her dirt covered bare feet - which you'll clean! She tells you that she already walked on this dirty toilet floor without shoes - who knows what's on this floor? And you'll know suck all that disgusting dirt of your mistresses' feet!
