My slave will serve me & my friend with his tongue. First, he must lick our sweaty armpits. We make sure he is not missing a single drop of our holy sweat. Then mistress Anja Black helps me undressing. She takes of my Latex hotpants & reveals my sweaty butt. Now she is guiding my slave´s tongue, to make sure he licks thoroughly over my butt cheeks. Of course my slave has to lick my sweaty butthole as well. Then I present a double funnel to my friend. We can both piss at the same time and our urine will run together in the middle, so that our slave will drink both of our piss mixed together. We will now use him as our human piss toilet and he will taste the perverted piss mix of 2 Mistresses.
