OTOUCH INSCUP 4 Gen 2 Suction Tech Premium Male Masturbator

The INSCUP 4 is built for users who want more than basic vibration—combining controlled suction with adjustable manual clamping so you can fine-tune both pressure and fit during use. The tighter, more focused sensation comes from OTOUCH’s second-generation suction technology, which works with the clamping system to create a deeper, more natural rhythm that feels noticeably more immersive than single-function devices. Two controls. One experience. Seven suction modes handle the rhythm. Manual clamping adjustment handles the fit. Run them together or independently—the combination gives you a level of personalization most masturbators don’t offer. Seven vibration modes let you layer vibration on top of suction and clamping, or use it on its own. Seven patterns mean you’re not locked into one setting. Built for repeated use, the smooth silicone exterior stays comfortable during extended sessions. The removable TPE inner sleeve pulls out cleanly for rinsing—no awkward cleaning workarounds. Discreet by design, the magnetic privacy lock with key access means the device stays sealed until you open it. Ideal for shared living spaces or travel. Care Instructions The main unit is not waterproof do not rinse or submerge the outer body. Remove the TPE inner sleeve, rinse thoroughly, and allow all parts to dry completely before reassembly.
