Mistress Wael was pissed at this guy and since she had tried to use other means to get to him and she could not, she felt that it was high time she changed tact and that is exactly what she did. She used her poo and pee to dominate the guy and he had no choice other than to change as he feared what she would do to him next.
Mistress Wael had an issue with her husband because he was not making her cum. She was disappointed and she felt that the best thing to do to him was to force him to eat her shit so that he learned his lesson and either learned to make her cum or at least be good at eating her ass or her pussy. He did his best to make him cum.
This guy was not only punished by being made to eat mistress Wael's shit. He was also made to lick her dirty and shitty asshole until it was clean. She had also peed on him because she felt that he deserved everything she did to him and even more. He was lucky she did not involve physical pain and just concentrated on humiliating and degrading him to the fullest extent.
Mistress Wael felt like she was not getting the truth from this guy and when she probed further, she realized that she was right. So she used her shit to punish the guy and to remedy the situation. She did not care what the guy felt and besides making him eat her poo, she also fucked him in the ass with her strapon. The guy regretted what happened to him.
