slave needs to put his mouth to good use... so we put hm to work as our shoe shine, polishing our shoes with his tongue. Using Mistress saliva to help shine and reprimanded for not being attentative. We want to see our reflection in our heels. By the way he deepthroats our heels we might be able to use his mouth in other ways! If he doesn't do a good enough job we will have to punish him.
