JOCK Advanced Helmet Humper Gyrating&Vibrating Silicone Masturbator

• Two-Motor Stroker, Head and Shaft: Most strokers stimulate the shaft only. This one adds a gyrating chamber dedicated to the head of the penis, the densest nerve area on the body.
• Hands-Free Wear: A stretchy base ring holds the unit in place during use. No grip required.
• Adjustable Internal Pressure: A flexible inner ring along the shaft sleeve dials in tightness, expanding appeal across user preference.
• Premium Silicone Build: Phthalate-free silicone interior, ABS plastic shell. IPX5 splashproof. USB rechargeable, built-in lithium battery.

The Jock Advanced Helmet Humper Gyrating and Vibrating Silicone Stroker is a hands-free dual-motor stroker. The upper section gyrates a chamber around the head of the penis. The lower section vibrates a textured sleeve along the shaft. A stretchy silicone ring at the base anchors the unit during use.

In use, both motors run independently from side buttons, supporting head-only, shaft-only, or full-coverage stimulation. The internal ring along the shaft sleeve adjusts for variable pressure, broadening usability across grip preferences.
