Slave Has To Smell My Sweat Odor

I make my slave take off my sneakers - I just finished a workout and my sweaty feet hurt - thats why he has to rubdown my stinky tired feet. Just what a loser is good for! But I wont make it too effortless for him - hell wear my sneaker on his face - with his nose sticking in it! He has to inhale my odor while he massages my feet and I get to unwind and love his humiliation!
