Bratty sadistic twins Viola and Valeria return home after a walk in the city center and call the slave for his daily duty: They command him to lick the street dirt from Her boots! The slave of course must obey and starts methodicaly to lick the dirt from the soles, cleaning them from the street grime! They look at him satisfied and disgusted at the same time, laughing at him. They love to see this pathetic slave licking Their soles. They keep using his tongue as a doormat, until Their soles are perfecty clean!
