Sucking Penis Pump

Description

Size Matter Sucking Penis Pump by Size Matters is a higher-spec electric penis pump aimed at users who want real suction power, multiple modes, and full waterproofing. It stays a bit budget on the cylinder material, but makes up for it with strong features and flexible sizing at the base.

The main tube is a clear ABS plastic cylinder. ABS does not feel as premium as acrylic, but it is light and durable for everyday use. A black printed measurement scale runs down the length, and there is light texturing on the outside to help with grip, especially when the device or hands are wet. Internal space runs to about 7.7–7.75 inches in length with around a 2.1–2.2 inch inner diameter.

At the opening, the pump comes with two premium silicone sleeves. One has a 1″ diameter opening and the other a smaller 3/4″ diameter, both stretching to match the user’s girth for a snug fit. The softer silicone boosts comfort around the base and helps create a reliable suction seal. Water-based lube pairs best with these sleeves.

The motor unit drives suction at up to 4000 RPM and sits at the top of the cylinder. The control panel has four buttons in a square layout: the top left is the power button, the top right (lips icon) cycles through 3 automatic sucking modes, the bottom left (suction icon) cycles through 4 continuous suction levels, and the bottom right handles suction pause and pressure release with single presses.

Above the buttons is an easy-to-read display that shows pressure information and makes it easier to understand how intense a session is. The unit charges via a front USB port, taking about 2.5 hours for roughly 1 hour of runtime. All parts detach, so the motor and sleeves can be removed from the cylinder for cleaning.

This pump is rated IPX7 waterproof, which means it can be submerged in water for short periods, making shower and bath use possible. Overall, it fits users who want an automatic, waterproof pump with real control over modes and intensity, and who are fine with a cylinder that feels basic but works well in practice.
