Mistress Zora lets the slave lick clean the soles of her high heels. The reason is her spit, which runs over her soles. She doesn't want to see any spit or tongue marks there at the end. So the slave has a lot to do, because Mistress Zora keeps spitting and won't let him rest! Her spit runs over the soles of her shoes and drips onto the floor. Come on slave! Lick THAT clean too!
