"Sweet and Sour Sauce" Is where The female takes a shit and rubs it all over her vagina, The male lays on his back mouth open while the female uses a vibrator to stimulates herself to allow her juices to mix through the shit and drip into the male's mouth. The Juice is the Sweet, The shit is the sour.
Jimmy: What happen in there?! You look sick!
