Mistress BlackDiamoond and her friend knew that this loser was supposed to be punished. So they did it with their foot worship. The mistresses were clean but for the punishment to work, they ensured their feet were dirty. They used the dirty feet to dominate the loser and forced him to lick them until they were clean. The loser was shocked but he learned from what had been done to him and promised not to make the same mistake twice.
