Lady Serena and her friend wanted to use the bathroom. They had drunk a lot but when they got to the house, their slave was in the toilet. He had a stomach upset so he was in there for a long time. The pressed mistresses tried their best to hold on to the pee but they lost the battle and had to pee on themselves. They were furious at the slave and waited to punish him.
Lady Serena felt like peeing and as fate would have it, her slave pissed her off when she was about to get up and go to pee. She chose to pee on him as punishment. It was a split-second decision and she implemented it. She enjoyed peeing on him and she surprised him with the pee punishment but he could do nothing about it and he learned never to piss her off.
