With one hand, hold the base of the penis firmly in an O shaped grip. With the other hand, use a circular motion starting about 1/3 of the way down the penis. Spiral your grip towards the top, giving extra attention to the head of the penis as your palm and fingers pass over it. When you're about to orgasm, get both hands just underneath the tip and use strong circular motions to try to "pop" your cork. Let the champagne fly!!!
