This guy thought that these mistresses were harmless and would not do anything to him. But he was wrong and the mistresses used their hard femdom fetish to punish him. He was forced to lick their asses and their pussies before they facesat him and they also peed on him. He was humiliated like never before and that is how he learned not to judge a book by its cover.
Mistress Jin did not have the patience of getting this slave to change. She had asked him to change and since he did not, she had to make him do it. She did not have the time to keep babysitting him to ensure he had changed. That is why she opted to make him lick her feet and then pee on him when he was done licking her feet. Thereafter, the mistress trampled him with her high heels.
