Slipper Sniffer Training JOI

Back for another slipper cleaning session. This time I want you to be my human vacuum. You will lick and suck the filth out of these slippers until they are brand new. Good boys do as they are told and clean as I say. If you do a good job I have a treat for you. Leave my slippers sparkling and I will drain that throbbing slave cock with. Ready to serve me?
