Slave's licking sand and dirt from My ankle boots mixed with My tasty spits

Description: I'm sitting in the chair and humiliating my pathetic slave-boy: i'm making him licking clean the sandy soles of my ankle boots with rough soles after a perfect date in the day before. he's licking and swallowing all the sand and dirt while i'm insulting him, telling him where i was been on the date in this shoes and spitting on then and on the floor making my slut lick it and swallow. when it starts bore to me i'm order him to lay down and i'm started wiping my shoes on his chest, face and tongue like on a rug while trampling him.
