Mistress Angelica and mistress Alice had a slave who was aloof and they did not like that about him. That is why they had to make sure that they taught him a lesson he had never been taught before. They turned him into a foot slave and he had to endure being trampled using high heels and licking their feet as well as their shoes. He knew what not to do after that.
Mistress Enola found out that this guy was forgetful and she did not like it because it meant she had to remind him all the time. The mistress was not prepared to do that so she used her dirty feet to punish him and make him realize that he had to change and he had to find a way to remember things so that he did not need to be reminded all the time.
When mistress Dana was upset with her boyfriend, she teased him. And as he looked at her big tits and her hot ass, all he had done to piss her off evaporated. But she had not forgotten. She waited until he was super turned on and she made him lick her dirty feet. When he was done, she denied him what he wanted which was to nail her. She told him to jerk off.
This mistress thought that this guy would be interesting but he ended up being boring and she could not imagine doing anything with him. So she had to show him what she did to people like him. The mistress made him lick her feet from the soles of her feet to sucking her toes. It was after that that she finally let him go and felt that he had learned his lesson.
