Your pumping experience will be more luxurious than ever before with the Universal Pump Sleeve. This soft and incredibly comfortable 1.5-inch-long by 3-inch-wide donut cushions your penis with soft and stretchy TPR, a material that’s made to please. Pumping works by creating an airtight seal around the base of your penis and, using suction, increases pressure and blood flow to your penis. This results in immediate harder erections and, over time, encourages your manhood to expand in both length and girth. The Universal Pump Sleeve fits over the base of your pump’s cylinder to create a more enjoyable and relaxed pumping experience. Slip this wonderfully soft donut around the entry of your favorite penis enhancement pump for a pumping experience that’s more pleasurable than ever. Uncomfortably firm suction is a thing of the past with this pump sleeve! TPR material is used on toys ranging from masturbation sleeves to dildos because of its amazingly soft and realistic feel. Treat your cock to an extraordinarily smooth pumping session with our pump sleeves! The donuts are stretchy and durable enough to fit most pumps for added pleasure. They’re body-safe and flexible to suit your pumping needs. Enjoy your most comfortable and pleasurable pumping session yet with the versatile pump sleeve!
