Mistress Zephy needed her boyfriend to know that she would not let him cheat on her again. She had been quiet and he thought that she did not mind and that he could do it again. He also thought she had let it go. But she had not and she was planning what to do to him. She settled on peeing on him on the balcony to send a message and a warning.
Mistress Zephy was out to shut this guy up and that is why she opted to cruelly teach him a lesson. She had tried to talk to him but it did not seem to help and so she had to make sure that she humiliated him in a way that he would never forget. The mistress used her pee to send the message and that did the trick as it shut him up.
This guy was extremely thirsty when mistress Zephy found him. She did not have any water to help him quench his thirst. So she had to think fast and help him. She did this by making him drink her urine. It was the only liquid she could give him and she did not hesitate to do so. He drank it hungrily as he had no alternative. He even ate her pussy as thank you.
Mistress Zephy was deeply hurt by her friend because her friend had betrayed her. Her friend realized what she had done and begged the mistress for mercy but she did not want to give it. Instead, she turned her friend into a pee slave and she fed her pee. The friend had to drink all of it before the mistress felt that it was enough and she let her go.
