What could make a sturdy, super-strong pump with automatic suction even better, you ask? Four levels of suction and fully waterproof design, obviously! Size Matters' Sucking Penis Pump has it all.

Included with your Pump's long, clear, cock-surrounding cylinder, you'll find two entrance sleeves in premium silicone. They'll maintain a magically airtight seal and feel great.

Up top, the removable power base controls three automatic (and easy-to-control) suction modes and four intensity levels. One button activates and pauses the pressure, while a set of two changes the pattern/intensity. Get in the tub or fill the cylinder with shower water to create your very own whirlpool of firming pleasure!

In silicone and ABS plastic, the Sucking Pump is phthalate-free and easy to clean and care for. Add slipperiness with any water-based lube you love. USB rechargeable, cord included. Waterproof.

*The Suction Pump Stroker is 11.6"/29.5cm long and 2.6"/6.6cm wide overall. It's 7.75"/19.7cm penetrable
