I want to humiliate my slave more; and my favourite game is to make my feet dirty from the ash of my cigarettes and him to lick them clean!! Of course he must obey and starts methodicaly to lick the soles, swallowing the ash and dirt! I look at him satisfied and disgusted at the same time, while rubbing my feet on his tongue and you will see that the ash is slowly removed from my soles.. The slave begs me to stop, but no mercy, I demand a perfect job so he must continue licking until my feet are almost cleaned!..
