The art of making a woman spontaneously combust from an amazing orgasm by laying her on her side and lifting her top leg straight up, penetrating her vagina at a constant but fast pace while you rub the clitoris with one hand, and finger the rectum with the other. It is a difficult task to get right as you may succumb to the uncoordinated failure of a similar multiple limb movement, the "tapping your head and rubbing your stomach" test. You may need to master this first before you move on to the mount everest of orgasms. Good luck.
