Mistress BlackDiamoond was asked by her friend to humiliate a slave for her. She agreed and she went about it slowly as she did not have anything better to do. That is why the mistress got the loser to lick her bare feet after which he had to lick her shoes as well. She made him take a break and then she trampled him for her own fun in order to see how he reacted and how he begged her for mercy.
