Created by and for male pleasure, the Boost Pumps brand will help you achieve the erection you have always wanted and the relationships you deserve. Get more satisfying sex with Boost Pumps. Thanks to its wonderful characteristics, you will be able to achieve what you have always wanted, powerful, thick, strong erections and above all, pleasant without the need to go to surgery or pills. The PSX04 pump has a clear cylinder with a meter, ideal to check how your penis grows with each thrust. You will only have to insert the penis into the cylinder and press the knob to see how your penis widens and grows, both in length and in thickness. When you think you have grown up enough you can hit the pressure release button for a happiest ending. You can combine your pump with the brands vibrating accessory (BO-086) and with the sleeves (BO-084; BO-085; BO-087). But if that wasnt enough, we include a silicone penis ring to increase pleasure. To achieve the best results, these pumps use the vacuum system, which causes the blood to concentrate on 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 with the pubis. You can clean comfortably and safely by removing the cylinder from the rubber. Remember to properly clean your pump with a good toy cleaner (N-507) and use your favorite water-based lubricant (N-506) for a crazy, super wet night.
