<p>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. <br> <br>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. <br> <br>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. <br> <br>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. <br> <br>FEATURES: <br>- 2‑in‑1 Penis Pump & Masturbator: Works as an electric penis enlargement pump and as a tight, textured stroker for powerful solo pleasure. <br>- Smart Training Modes + Manual Control: Front‑end intelligent technology with preset exercise modes and adjustable suction cycles, plus manual mode so you can control pumping and air release yourself. <br>- 4D Textured Magic Sleeve: Soft, high‑quality material with an internal 4D tunnel that simulates a real, deep “throat‑like” or canal sensation, increasing friction and arousal. <br>- Clear Cylinder with Magnifying Effect: Transparent tube lets you watch your growth and movement, with a magnifying effect to enhance visual stimulation and confidence. <br>- Comfortable Size & Fit: Approx. 61 mm inner diameter cylinder, designed to create a strong seal when used with lubricant and trimmed hair. <br>- Detachable & Easy to Clean: Cylinder and sleeve can be removed and washed after use. (Pump head: wipe only, not washable.) <br>- USB Rechargeable & Quiet Motor: Rechargeable via USB (power bank, charger, laptop) with low‑noise operation for discreet sessions. <br> <br>SIZE: <br>- Cylinder inner diameter: 61 mm <br>- Cylinder outer diameter: 65 mm <br>- Model without sleeve: Overall height: 305 mm, Insertable length: 220 mm <br>- Model with textured magic sleeve: Overall height: 320 mm, Insertable length: 235 mm <br>- Charging Time: 120 minutes <br>- Running Time: 110 minutes <br> <br>HOW TO USE <br> <br>Prep & Lube <br>Ensure the vacuum cylinder and body fit tightly; trim pubic hair if needed for a better seal.
