I return from a lengthy run and the slave's waiting for me at the car. I sit down on the driver's seat and make him lick the dirty soles of my running shoes clean for starters. Then I take the first shoe off and immediately press it on his nose - followed by my sweat-soaked sock! After smelling the second stinky shoe and sock I order him to lick all the foot sweat off my feet! He's clearly disgusted, but he won't be allowed to stop until he licked every square inch of my sweaty feet!
