Cathy's boots are very dirty. And that has to change soon! So she orders YOU to clean her boots again. Or course, with your tongue only! You have to to with the back of her soles and move on to the front. If you do a good job she will take off her boots eventually and you can lick her feet! But her feet are very dirty too! Even more than her boots... You can easily recognize the dirt on them! But this will make you really horny, won't it...!?
