Two Domiatrixes use him for Facesitting and as Piss Toilet

Princess Nikki and I will use my slave as our full toilet today. First, I will use his face for facesitting and make him lick my butthole. Of course my slave also needs to lick Princess Nikki´s butthole, until she is satisfied. She tells him that if he does not stick his tongue deep enough into her ass, that she will smother him without mercy... Now I really need to pee. I use a glass and fill it again and again with my delicious piss. My slave feels tormented, that I make him drink such big amounts of piss; especially because he knows that we want to use him for even more later on...
