The Smart Automatic Penis Pump & Masturbator Sleeve is built for men who want both performance training and intense pleasure in one discreet, powerful device. It works as a vacuum enlargement/exercise pump and a deep, textured stroker, so you can train harder erections and enjoy a tight, realistic sensation at the same time. Inside the clear cylinder sits a soft 4D magic sleeve that grips and strokes the shaft. As the electric pump builds negative pressure, blood is drawn into the penis, helping support firmer, fuller erections over time. When you’re ready for pure pleasure, you can use it as a masturbator and enjoy the snug tunnel and visual thrill of watching yourself grow inside the transparent chamber. The built‑in smart chip offers multiple exercise modes with automatic pumping and release cycles. Choose from different stages (pre‑use, adaptation, intensification) or switch to manual mode for full control of suction strength and timing. The sleeve is detachable and washable, and the ultra‑quiet motor keeps your sessions discreet. With interchangeable sleeve entrances (mouth, vagina, ass on compatible versions), USB charging, and a comfortable 61 mm inner diameter cylinder, this 2‑in‑1 toy doubles as a training tool and a powerful orgasm machine.

Apply lubricant to the bottom of the silicone or MAGIC sleeve and to the penis. Insert the penis and press the vacuum cylinder firmly against the pubic area to prevent air escape. Start Pumping Start the pump slowly. You will feel a stretching sensation as air is pulled out of the tube. Continue pumping/releasing until you find a comfortable pressure level. Exercise Cycle Keep pressure for a while, then release. During the break, massage the penis with the sleeve to enhance blood flow. Repeat the pump/hold/release cycle. In Smart Mode, set the exercise data first; the pump will then run the pumping and releasing cycle automatically. After Use Remove the vacuum cylinder. You may add a cock ring to help maintain erection if desired (do not use for more than 30 minutes). Clean detachable parts with warm water and mild soap or toy cleaner. NOTE: The head with buttons can't be washed with water. Transparent cylinder and sleeve are removeable & could be washed with toy cleaner / warm water.
