Piss in slave's mouth before he fucks me

This is a mostly candid recording of facesitting and sex with Kitten. I ride his face while teasing and playing with his dick. As he is licking my pussy, I decide to piss a little bit into his mouth. I can tell he likes it because it makes his little dick get really hard, so I keep doing it. I leak pee into his mouth for about 3 minutes while he eats me out and takes it all. Eventually I need him to make me cum so I lie down and he crawls into his place between my legs. He licks me until I cum with piss all over his face. His eyes are so desperate. I let him fuck me while I tell him about all the waste he is going to consume from my body. He is going to eat both at the same time and live only to eat what I give him. He whimpers and screams into my boobs as I degrade him while he fucks me. He looks so small and weak compared to me! I go on to remind him that his dick is going to be replaced by a strap on someday, so I can feel something much bigger!
