Penis pumps are the most advanced non-surgical erection enhancers on the market. The XLsucker is a plastic cylinder that fits over your penis and helps you achieve an erection or a larger erection through suction. As the air is sucked out of the cylinder, the vacuum pulls your penis into the cylinder, allowing more blood to flow into it. After removing the cylinder, the result is a temporarily larger penis and a more impressive erection. It is designed to add length and girth to the penis or to achieve and maintain an erection. The XLsucker creates a vacuum in the chamber that then draws blood into the penis, enlarging it. Pump users typically report an increase in their length or girth after regular use of the penis pump. To achieve the best effect, you should start slowly. Apply some lubricant to the base of the pump to ensure a good seal. Insert your penis (but not the testicles) into the cylinder, press the pump slowly, and watch your penis grow. Pay less than for other pumps with this easy-to-use one-step enhancement system. You will find that pumping also enhances intense sensations for masturbation or sex with a partner. Never pump to the point of pain. Pumping should be fun. - High-quality clear plastic casing with marked measurements. - Air release at the push of a button. - Convenient automatic electronic trigger. - Requires 4 AAA batteries (not included). - Made from TPE and ABS plastic.
