You never know when you are going to get some action, so you better be ready when you get the call guys! Meet the Cocktrainer, the latest stamina-training masturbation device developed to prevent premature ejaculation and help you perform like a pro. The stroker includes a stretchy silicone cock ring that features a built-in motion sensor to monitor and count your strokes. The super tight masturbator will increase your endurance, prolong ejaculation, and ultimately extend the fun when its time for you to perform. Unlike ordinary cock rings and masturbators, the Cocktrainer features a hidden trainer to monitor your strokes and help motivate you. The easy to read LED screen displays a clear readout and the ring can be removed from the masturbator and slid on your cock to help maintain thick throbbing erections.
