Another great one from Nasstoys is this Mack Tuff Vibrating Power Pump. Powered by 2 AA batteries (sold separately so be sure to pick some up) this dick pump is fitted with a vibe that is capable of variable speeds to make pumping your meat a more joyful experience. As its primary function you can expect a bigger you in a short time as you use the ball pump to create vacuum pressure and make your johnson larger while you see it all through the clear general purpose polystyrene tube.
