Foot Smelling During My Workout

Next lesson for my workout slave. He can carry the training bench on his chest while Im doing some crunches on it. Truly comfy as I can rest my sneakers on his face - but thats only the beginning. After a while I take off my footwear and order him to smell the stinky inwards of the footwear and my socked feet. In the end I also take off my socks and he can smell them and my sweaty nude feet.
