Invisi-Rider Enhancer

Invisi-Rider Enhancer

Ships: Within 24hrs

$26.99

The principles behind penis sleeves is, in many cases, similar to that of cock rings; the sleeve pleasurably squeezes the penis, and forces it to retain large quantities of blood, enhancing both the duration and intensity of the erection. This is the case with the Invisi-Rider Enhancer, a bead-enhanced sleeve for your penis!

The Invisi-Rider is made of high-quality, unscented TPR, and measures 3.5" long by 1.5" in diameter. The Invisi-Rider is really more a penis extender than a penis extension per se, since it expands the diameter of the penis rather than the length. It features 3 stainless steel beads embedded in its material, adding an extra layer of pleasure, particularly for the user, while Invisi-Rider Enhancer’s soft ribbing supercharges sensations for the partner!

This thick, ridged penis sleeve is ideal to not only bring added pleasure to you and your partner, but to help you maintain a raging hard-on longer than you could have imagined, and help you and your partner achieve explosive orgasms! The Invisi-Ridge Enhancer is easy to clean and maintain, and will provide you with years of trustworthy service! Please note that colors may vary.

Soft and stretchy TPR
3 stainless steel embedded beads
Ridged for her pleasure
Helps maintain your erection for longer
