Mistresses Amarena and Althea had warned their slave not to touch what didn't belong t him, yet curiosity won over caution. When they found out, their patience snapped. He had to realise that their orders were not suggestions. The violation of boundaries enraged them more than the act itself, and they planned to make him understand what he had done. Punishment would be the only language he could comprehend now, which drove them to pour piss on him and force him to eat their shit
Mistress Xenia and her friend mistress Amarena were dared by their co-worker, and they laughed at what he did because they knew that he didn't know what he was doing or who he was messing with. They ignored him and went about their business, but he did not stop bothering them so they had to act. The mistresses chose to make the poor guy eat their shit as well as drink their pee before letting him go.
Mistresses Amarena and Lith wanted information from this guy, but he was working with the competitors, who would not give it to them. They were super pissed because they wanted it urgently. They stood to lose a lot, as they were not going to sit back and watch what they had worked hard for going down the drain. They turned the guy into their human toilet and fed him poo for him to give them information.
