Description

Customize your fit with this tightening masturbator! This stretchy, soft, TPE tunnel sits inside of a plastic case and can be adjusted to get smaller or larger for your shaft size and preference.

We chose the Curve Toys Jock Vibrating Double Stroker - Black because it considers the user the way good design always does — quietly, completely. Jock is one of the few houses we trust to refine this category.

Sleeved in abs plastic, silicone, thermoplastic elastomer (tpe) — soft, body-safe, designed to be cleaned and stored properly so it lasts.

Inside, the texture is thought through — multi-function, multi-speed, multi-vibration patterns. The kind of considered detail that's only obvious in use.

Length — 4.7 inches. Insertable — 4.2 inches.

The Curve Toys Jock Vibrating Double Stroker is a customizable masturbator designed for personalized pleasure. Made by Eldorado, this rechargeable stroker features adjustable TPE tunnel expansion from 0.7 to 1.38 inches and multiple vibration patterns. It's ideal for solo use, offering a comfortable and adaptable experience for a wide range of users.

This Jock masturbator from Eldorado offers a uniquely adaptable experience with its innovative tightening mechanism. Unlike rigid strokers, its TPE tunnel expands from 0.7 to 1.38 inches, allowing you to dial in the perfect tightness. The dual-hole design provides two distinct entry experiences, catering to your preference for a snugger or slightly looser fit.

Common questions

How do I adjust the tightness of this stroker?

You can adjust the tightness by turning the ring around the plastic case. This action expands or contracts the internal TPE tunnel, allowing you to customize the diameter from 0.7 to 1.38 inches for your ideal fit.

What kind of lubricant should I use with this Jock stroker?

For the best and safest experience, use only water-based or silicone-based lubricants. Avoid oil-based lubricants as they can degrade the TPE material and affect the toy's integrity over time.

Is this masturbator easy to clean?

Yes, cleaning is straightforward. Rinse the stroker with mild soap and warm water after use, then allow it to air dry completely. Ensure both caps are on for dust-free storage.
