Give yourself a boost with this sucking penis pump! The clear, plastic case attaches to a powerful, sucking motor with an easy-to-read display! On the other end, you can attach either the 20mm or 25mm silicone sleeves and slip your shaft inside to get swollen from the suction and pressure! The display shows you the exact amount of pressure and is easy to control and use. Choose between 4 intensity levels and 3 suction modes that stiffen your willy and suck your rod intensely! Rated IPX7, it is waterproof and can be submerged underwater for up to 30 minutes! Enjoy it in the shower or bathtub for a unique, wet experience! Want to switch it up? You can use this tool to get hard and then swap out the sleeves provided for a realistic, textured sleeve and enjoy the sucking sensation as you stroke yourself! All the pieces are detachable so you can easily clean up. Simply remove the motor from the case and slip off the silicone sleeves. Wash with warm water and mild soap, then rinse, spray with a toy cleaner and pat dry. Grab your lube and rub it on your shaft and the entrance to the sleeve. Then start to slide your shaft inside the case. If there's any resistance, use some more lube to help it glide in. Turn the toy on and start to play with the settings. If it gets too intense, simply break the seal to release pressure or press the Suction Release button! Practice increasing the pressure 30 seconds at a time and then releasing it. Do this again and again before starting to play with different suction modes and intensities. Before you know it, you'll be hard, twitching, and ready to play with your partner or blow your load!
