The ins and outs...
You: lying on your back with legs outstretched and slightly open. Put a pillow under your bottom to make access easier and to allow deeper penetration.
Him: as if he was about to do press-ups over you, he supports himself on his arms and puts one hand on each side of your face. With your hands on his bum, encourage him to make figures of eight inside you.
Why is it so good? This angle of penetration enables your partner's penis to go very deep but it's the figure-of-eight movement that allows him to reach and stimulate your deepest, untouched parts. An added bonus is his penis rubbing against your clitoris, which is explosive!
A good time to try it: After a night on the dancefloor, when you're tired but still up for a tryst...
Tip: Get him to so variations on a figure-of-eight to give you different sensations. An eight on its side is the symbol of infinity...and you thought he was afraid of commitment!
