It's no magic wand, but the Deep Suction by Spank will definitely conjure up a stupendously firm erection ready to go the distance. A user friendly design makes for a great experience for beginner to master pumpers, simply slide on into the firm plastic cylinder and squeeze the vertical finger grip pressure valve to activate inner suction.  Steady inner pressure draws blood to the penis while a soft silicone donut sleeve around the entrance cushions skin. That sleeve also helps create an airtight seal, by the way, something you definitely want when pumping.

Graduated measurements run up the side, so you'll be able to easily track progress with those as well as through the clear cylinder walls. Assembling easily and quickly and coming apart just as fast for through cleaning, this pump can be transported just about anywhere.

In firm plastic and soft silicone, the Deep Suction cleans easily using warm soapy water or a good toy care fluid/foam. If you'll be using a lube, please pick a favoritewater based version- avoid silicone lubes as they can break down the silicone donut sleeve.
