Enlarge your penis and simultaneously enjoy a great stimulation with this penis pump from the EasyToys collection. The pump makes sure the blood stays in your penis, so your penis will swell up and your erection will feel harder and last longer. Apply some water-based lubricant to your penis and to the opening of the pump and let your penis glide inside. Use the squeeze ball to create a vacuum inside the pump. There is a ruler on the side of the pump, so you can check your progress.
