First of all, take a real piss!

Oh, I got a pressure on my bladder! I think there's some champagne coming out of my pussy today. I'm just gonna find a position where you can watch me do it. And then I'm just gonna let it go... or rather, shoot it. It's liberating and awesome how the piss shoots out and it just doesn't stop. I picture you lying underneath it and me pissing all over you. A great thought! You could jerk off and I'd piss on your dick? Would you like that?
