You're in your position as requested, sitting on your knees with your head tilted back and mouth wide open while you look up at me. I tell you that you are to keep your mouth open with your jaw spread wide until I give you instructions otherwise. I slowly start to spit into your mouth, using you as a spitton. I tease you with my mouth, lips and tits until I have filled up your entire mouth with my drool and spit. You aren't allowed to swallow until the end, when I give you a countdown, and then you will feel all of my essence sliding down your throat until your belly is full of my spit.
