The double handjob is an extremely sexual position that lets you give oral pleasure to your partner while penetrating her with your penis. It is the best way for a guy to pleasure his partner because it gives him the greatest view possible of her big beautiful boobs. Unlike a handjob, where you can only penetrate up and down, in the double handjob you can go from behind to behind. This position will also make your girl scream loud when you are performing the handjob..
