The Mermaid

Lie faceup at the edge of a bed, desk, or countertop. Place a pillow under your butt to get some elevation. Extend your legs straight up, keeping them close together. You can put your hands under the pillow to raise your pelvis even higher, use them to hold on to the counter or desk for leverage, or keep them free. Your partner then enters you while standing up; if the bed or desk is low, he can kneel on the floor. He can grip your feet for leverage, which will give him the extra stability he needs to thrust more deeply. Keeping your legs together means he feels fuller inside you, so you're creating lots of blissful friction and an incredibly tight fit. Give him a show and drive yourself wild by stimulating your clitoris while he's thrusting away.
