Pump things up with a digital pumping system! Compatible with many Size Matters cylinders for the penis, vulva, nipples, and more. This device features an electric pump and a sturdy silicone connection hose.

Two simple control buttons make pumping easy, allowing you to lose yourself in the moment. Just press the start/stop button to initiate and end the strong vacuum that builds up in the cylinder. Are you ready to play with your swollen body parts? With the quick release button, you can swiftly move on to the next chapter of the game.
