I jut returned from a very good gym workout, my shoes, socks and feet are dirty and sweaty. But that’s what I own a slave for! I hold him on a tight leash as I use his tongue to clean the bottom of my running shoes first, then I make him clean my socks and feet too while I relax. I trained my slave to do whatever I say, even if it’s removing the dust from the bottom of my dirty running shoes.
