I have invited 6 girlfriends to my party, and one slave to serve us however we choose. But it is a party, and champagne is a very accepted beverage. But for the slave we are not talking about the boring bottled one, No! We are talking about champagne directly from all our pussies.
So we gather around him, and the pee party start. We take turns in peeing in his mouth, and he have to use his tongue as our toilet paper when we are done! This should be an perfect evening of toilet slavery for my slave!
