Lady Serena and her friend are naughty and adventurous. They wanted to have a little fun. They chose pee fetish because they had never tried it before. These mistresses did not have a slave so they had no choice but to try the piss movie on their own. Wearing jeans, the mistresses, took a piss on themselves and fantasizes about how they would use that to humiliate and punish slaves and losers.
Lady Serena was shocked to learn that this guy had a thing for her pee. She tried to think about it but it did not make much sense to her. She chose to try it being an adventurous mistress so she went with the loser to his place and she peed on him. She actually enjoyed it but still wondered what was in it for him as he seemed to enjoy it more than he did. Probably it was being able to see her ass and pussy so close to him.
