Lady Ayse and her friend had asked this slave to do some work for them but he did not do it as well as they had expected he would do it. So they had to punish him and they did it cruelly. The mistresses slapped the shit out of him and they made sure that he agreed to be their living ashtray. It was fun for them doing it to him.
Lady Ayse knows that when someone is scared of you, they will do all you ask them to do. And that is why she wanted to dominate this guy. She felt that words alone would not do it and that is why she opted to use her pee to do it. She turned the guy into a pee slave and he had no choice but to drink her urine and lick it too.
