Domination Overload with two young Mistresses

Me & my friend Miss Kirsch will use a human toilet together. We call him in and explain his duty to him: We will pee right into his mouth and want him to flush it all down. We tell him to stand up, so we can take a look at his hard dick. We mix teasing with dick slapping and even put cable ties around his erect cock. As soon as we can't hold it anymore, we tell him to lie down in the shower. I squat over his face and pee right into his mouth, while Miss Kirsch has her boot on his balls. He is already struggling a lot to drink my piss. This will be a lot of fun...but only for us!
