Mistress Suzy had an issue with her man and she needed to instill some discipline in him. She felt that she was getting a raw deal from him and that is why she did what she had to do to him. The mistress forced the poor guy to lick her ass and she went ahead to make him lick her feet, her shoes and to gag on her foot before she felt it was enough.
This loser needed to be put in his place and that is exactly what this mistress did. She did not want to let him think that he could get away with whatever he did and that he could go on thinking that he was the boss when he was not. That is why she chose to make him lick her dirty feet as she read a book. He could not do anything about it.
This slave needed to be foot gagged because of the nonsense he had been doing. Mistress Suzy had tolerated him enough and she felt that it was time to punish him and make him accountable for all that he had been doing. The mistress did not hesitate to punish him and she made sure that he was in pain as she foot gagged him. The punishment worked as intended.
