Your partner lies on his back, his legs straight out in front of him, a pillow under his head so he can watch the action. You straddle him with your head facing his feet. With your hands on the floor for support, you back up onto his penis. He holds your upper thighs or butt tightly while you thrust. You pick the angle and speed of the thrusting, so there’s plenty of opportunity to experiment and find your inside hot spot. Get a rhythm down — circle for a few times before you take an unexpected plunge. It gives you maximum control for an intense orgasm, but your guy gets to savor every sensation without working up much of a sweat. And he’ll love the total visual and tactile access to your backside.
