Mistress Rosella and her friend mistress Contessa had a checklist of things they wanted to do within the next 100 days. The next item on their list was pee fetish. So they rented a slave as they did not have one and had fun humiliating him. They used an improvised toilet to piss directly into his mouth and he drank all of it. He was lucky they did not use him for the next item on the list.
