A device used to enlarge the penis. Pumping the handle will remove air to create a vacuum in the pump. This will only enlarge your penis temporarily. If used obsesivly it will stretch the skin on the penis but not lengthen it, your skin will sag off of your penis
Some guys like to use penis pumps in the bedroom
