The Power Pump is a penis enlargement pump and erectile dysfunction aid for men. Its simple but effective action enlarges the penis by creating a powerful vacuum inside a plastic cylinder into which the lubed up penis is already inserted. A one handed squeeze action on the pump quickly creates a powerful suction vacuum and immediately increases blood flow into the penis causing an erection. The vibrating bullet attached to the side of the cylinder provides stimulating pleasure, but we say it is the vacuum pump that does the job with this sex aid toy. Maintain the vacuum until you feel the penis has achieved the required level of erection then release the safety valve for quick relief of the vacuum pressure. If you loose your erection, repeat the vacuum process. Sustained use of penis pumps over a long-term period can improve the muscle tissue and penis size. The rubber skirt at the base of the cylinder is removable to enable easy cleaning of the cylinder. The pump detaches too. This is an inexpensive penis pump that works. Always use a quality sex lube such as ID Glide with this erection sex aid (see TurnMeOn Essentials). Free lube sample provided. Swift and discreet delivery.
