After I had a slave humping My boots, they're all dirty! I can't go out in them like this!! You've been assigned the task of licking them clean. I won't let you forget what an honour this job is, to be put on your knees using that bitch mouth to remove all the dirt on them... let Me see how black your tongue is from all the filth from the soles... if you don't clean them properly a punishment will surely be due!
