The Jackmatic pump, by American manufacturer Nasstoys, is genuinely one of the best pumps we have seen for the price. With an eight inch long barrel and a special rubber seal at the base it's designed to be used one-handed; simply slip a bit of lube on, place over your penis, and squeeze the hand bulb to create a vacuum in the chamber. This will bring blood rushing to your penis, supercharging your erection to sizes and sensations you won't have felt before! When you've finished using the pump (we recommend for not more than 20 minutes at a time to start off with) you can slip a cock ring (not provided) over the base to keep your old chap standing to attention while you use him for more fun activities!
