The Smart Automatic Penis Pump & 4D Masturbator is a 2‑in‑1 men’s toy that blends performance training with full‑on pleasure. Use it as an intelligent vacuum pump to help improve erection quality, then enjoy the tight, textured inner tunnel as a powerful masturbator. Inside the transparent cylinder sits a soft Magic Sleeve with a 4D textured canal that hugs the shaft and creates a deep, realistic stroking sensation. As the electric pump builds negative pressure, blood is drawn into the penis, helping promote firmer, fuller erections. The clear tube and magnifying effect make every session visually exciting as you watch yourself grow and thicken. A bright LED display shows real‑time pressure (kPa), time and mode, so you always know exactly how intense your workout is. Built‑in smart technology offers automatic pumping and releasing cycles with different training stages (pre‑use, adaptation, intensification), or you can switch to manual mode and control every pump and release yourself. The high‑quality Magic Sleeve comes in multiple entrance styles (mouth, vagina, ass on compatible versions), letting you choose the fantasy you want. The motor is ultra‑quiet and designed for anti‑air‑leakage, and the cylinder and sleeve are detachable and washable for easy cleaning. USB charging keeps it ready whenever you are. Whether you want to build confidence with regular training or just enjoy intense hands‑free pleasure, this smart 2‑in‑1 pump and masturbator is built to do both.

Designed to sit comfortably against the body and minimize air leakage. - Detachable & Easy to Clean: Cylinder and sleeve can be removed and washed after use.
