Goddess Harley wanted to humiliate her ex and that is exactly what she had him do. The mistress chose to make the guy lick her feet and she also had him jerk off as she watched. He was shocked by what she did but she had warned him that she did not want him to continue bothering her as they were no longer an item but he did not listen. So he had himself to blame.
Goddess Harley knows how to tease and deny and that is why she chose to degrade this loser. She did it for fun and by the time she was done with this loser, she had humiliated him and made him know that he was not what he had thought he was. He thought he was a lady magnet but he realized that that was far from the truth and he stopped having high expectations.
