I walk my fat-ass slave on a leash to get him some much needed exercise. To showcase him his place in the pecking order I make him smooch my boots and spank his butt. All of the unexpected I have to pee so I think to myself why not piss in a cup and make him drink it? Hes certainly thirsty after all that exercise : My pee is dark and intense, I am sure he will enjoy it! I give him a few sips, walk him a bit more, some spanking, and then another sip until its all gone.
