How it's done: Lie down at the edge of a bed, desk, or countertop. Extend your legs straight up, keeping them close together. You can put your hands under your butt to elevate your pelvis, use them to hold on to the counter or desk for leverage, or keep them free. Your partner then enters you while standing up (or if the bed or desk is low, kneeling on the floor). He can grip your feet for leverage, which will give him the extra stability he needs to thrust more deeply.

Why you'll love it: Keeping your legs together means he seems fuller inside you, so you're creating lots of feel-good friction and an incredibly tight fit. And you can easily use your hands for clitoral stimulation to drive yourself wild while he's thrusting away.
