Cleaning my dirty riding boots on his hands

Description: This slave's hands are going to suffer a lot today - not only am i going to trample them under the hard soles of my riding boots - but on top of that, the boots are really dirty and the dirt will act like sandpaper on his skin as i walk over his hands and grind my boots on them. he really struggles to deal with the pain my full body weight causes his fragile fingers and weak hands - and with the pain the dirt causes his skin - and the with the fear of his fingers actually being damaged for a long time by the hard boot soles. but for me it's a lot of fun ... i enjoy hearing his screams of pain and seeing the feat in his eyes. let's see how long it takes to get my boots nicely clean again!
