First find a chair with a sturdy back, have him sit facing forward. Straddle him with your feet on the floor, slowly lowering yourself onto his erection with your knees bent at a ninety-degree angle. Once he's fully penetrated you, begin to slowly rock back and forth.
He remains standing and lifts you up so that you can wrap your legs around his waist. From there he'll cup your buttock and slowly move to enter you, controlling the depth of penetration. For balance, have him stand near a bed or a wall. This position is great for women who like it when their partners are in control—and have some serious upper body strength.
