I was in the garden without footwear all afternoon and my feet are indeed filthy - covered with thick mess - so much you can see on the floor where I walked in. I sit down on the barstool and instruction my slave on his knees in front of me. I stick my feet out into his direction and shove them into his face instantaneously. I embark effortless by massaging them all over his face - before ordering him to lick them clean. Then he has to lie down on the floor so I can comfortably rest my feet on his face and rub the dirty soles over his tongue. Later I also stand on him and make him lick my feet. In the end you can see how spotlessly clean my feet got!
