Two transparent acrylic cylinders attach directly to the nipples and draw them up with a steady, controlled suction — all from one easy-squeeze trigger handle you hold in your hand.
Independent on/off valves on each hose let you dial in exactly how much sensation each side receives, and a quick-release valve means you can ease off in a second.
The silicone hose detaches while the cylinders maintain their seal, so you and your spouse can move freely and stay in the moment.
