JOCK Vibrating Double Stroker

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. Choose between 6 different tightness settings by turning the ring around the case to larger or smaller. Inside the tunnel are textured nubs that add to the sensation! Enjoy using it with the cap on one side or take it off for a cum-thru tip! Each side has a slightly different-sized hole, so you can choose which side you'd like to enter depending on how tight of a squeeze you want!

Designed for maximum control and comfort, the JOCK Double Stroker uses a phthalate-free, body-safe soft TPE that feels incredibly plush against skin while still being resilient enough for repeated use. The non-slip outer case gives you a confident grip, so you can focus on the rhythm and pressure without slipping. Pair it with generous amounts of lube for a smoother, deeper glide—water-based or silicone lubes are best for long-lasting performance.

• Custom Tightness: six levels you adjust via the outer ring on the case for a fit that matches your shaft size and mood.
• Textured Tunnel: nubs along the tunnel amplify sensation and stimulation with every stroke.
• Two Hole Sizes: each end of the tunnel has a different entry size, letting you pick how tight or open you want the feel.
• Cum-Thru Tip: remove both end caps for easy cleaning and a cum-through finish for a different sensation and cleaner play.
• Soft TPE & Body-Safe: phthalate-free, super-soft, and stretchy for a comfortable, worry-free experience.
• Non-Slip Outer Case: secure grip so you can stroke with precision and confidence, even with generous lubrication.
• Easy Cleaning: rinse with mild soap and warm water, air-dry, then re-cap to keep dust and debris out.
• Lubricant Friendly: works best with water-based or silicone lubricants for a slick, long-lasting glide.

How it works and why it’s different

Unlike standard fixed-tension strokers, the JOCK Vibrating Double Stroker evolves with you. The outer ring lets you dial in the squeeze to perfectly suit your mood, from a gentle tease to a firmer grip that heightens pressure and friction. The dual-entry design gives you choice—enter from the tighter or the wider side depending on the level of resistance you crave. The cum-thru option adds a playful, open-ended finish and makes cleanup quicker after your session.
