Licking The Boots Clean

Ughh... these boot feet are indeed dirty! I dont like them to be dirty - good thing I have a slave here to munch them clean! I want him to gobble the soles of my boots and shine them with his tongue! Of course Im watching him closely - I need to be sure he does it well - and he is not allowed to stop until I tell him to stop! Look at this closely - maybe youll be the next one to clean my dirty boot soles!
