Lady Scarlet did not want this loud slave to waste her time and that is why she chose to punish him for his loudness. She chose to use her shit to do it and it was gross and cruel. He had to eat her poo and lick her asshole clean before she was done with him. He never forgot it but he also stopped being loud so as not to anger her.
Goddess Wu needed her chauffeur to be on time and when he was not, she had to punish him. She did so using her hot ass to be precise. The mistress not only gagged him, but she also had him eat her shit and lick her ass clean before she gave him a second chance. He now knew better than to piss her off so he kept time and did not disappoint her.
