Justine has been walking around in her dungeon all day to try to get her feet gross and dirty for you. Now that they are black and disgusting, she couldn't possibly put them back into her fetish shoes! Nope, you are going to have to lick them clean for her. Don't worry, she will tell you exactly how to do it. You are going to have to scrub them with your mouth and you will not be free to go until she thinks you've done a good enough job. Don't you just love dirty, pretty things?
