This guy had an enemy who wanted him degraded and humiliated. So he paid the mistress to torture and humiliate him. Since the money was good, the mistress agreed and she had fun torturing and degrading him. He was turned into a foot slave, he was trampled and he was also teased and denied by the mistress. The slave had to lick her boots clean before she let him go. She had so much fun that she forgot why she was doing it.
