Erotic instructions: Bend over the side of the bed so your stomach and breasts are pressed against the mattress and your feet are on the floor, legs spread comfortably. As your guy penetrates you from behind, he lifts your legs from just above the knees, holds them apart and thrusts, reveals Lynn, 24.

Pleasure payoff: With your body angled slightly downward and your legs apart, he gets deep penetration. And since your gams are in his grip, he can thrust away with total abandon. Plus, he can easily view your sexy rear and watch himself move in and out of you -- an up close and personal pose guys pine for. So what's in it for you? You feel weightless with your legs lifted off the floor, as if you're floating, while your guy does all the work. And his penis is perfectly angled to stroke your G-spot, she adds.
