The PSX10 pump has a transparent cylinder with a meter, ideal for checking how your penis is growing with each thrust. This pump is automatic, it has a button to start with a lighter pressure, another button to increase the pressure, and another to quickly release the pressure. You will only have to insert your penis into the cylinder and press the button you want to see how your penis widens and grows, both in length and thickness. When you think you've grown enough you can press the pressure release button for a very happy ending. You can combine your pump with the brand's sleeves (BO-084; BO-085; BO-087). But if that wasn't enough, we include a silicone penis ring to increase pleasure. To achieve the best results, these pumps use a vacuum system, which causes blood to concentrate in the penis, whether it is flaccid or erect. If the penis is flaccid, you will achieve a perfect erection through a tight and comfortable seal located at the end of the cylinder, at the junction of the penis and the pubis. You can clean it comfortably and safely by removing the rubber cylinder. Remember to properly clean your pump with a good toy cleaner and use your favorite water-based lube, visit NANAMI to find your favorite.
