When a man is receiving oral sex from their boyfriend/girlfriend, they take their balls and put one on each side of the shaft so that it looks like a Cannon on rolling wheels.

This must be timed correctly so that when the pubic hair is completely burnt away the man orgasms down the others throat (Like a cannonball firing)
