The Undy Waved Hollow Penis Plug delivers precision urethral stimulation through its distinctive wavy texture while allowing fluid passage during extended wear sessions. This premium stainless steel device features graduated sizing from 8mm to 10mm diameter, creating controlled stretch alongside the textured ridges that massage your urethral walls with every movement.
Each ridge along the wavy shaft creates distinct pressure points as you insert this hollow plug, sending focused sensations directly through your most sensitive internal nerve endings. The graduated diameter starts narrow for comfortable entry, then widens to provide that satisfying stretch as you work deeper. Unlike solid plugs, the hollow core lets you maintain natural functions during extended wear while keeping that constant internal presence.
The integrated glans ring secures everything in place, preventing accidental slipping while adding visual appeal to your anatomy. Temperature play becomes incredibly intense with the steel construction—chill it for shocking contrast or warm it for soothing heat that radiates through your entire shaft. Every thrust, movement, or even walking creates subtle shifts that remind you exactly what's filling you.
Start with thorough cleaning of both yourself and the plug, then apply high-quality sterile lubricant generously. Insert slowly, allowing your body to adjust to each ridge as you progress deeper. The graduated sizing helps your urethra accommodate the increasing width naturally—never force or rush the process.
Once fully inserted, the glans ring should sit comfortably behind your head, holding everything securely in place. The hollow design means you can wear this for extended periods without removal for natural functions. Remove slowly when finished, cleaning thoroughly with antibacterial soap and allowing complete air drying before storage.
This plug works best for experienced urethral play enthusiasts who want extended wear capability combined with intense textural stimulation. The 8-10mm sizing suits most anatomies, though complete beginners should start with smaller diameter options first. Anyone interested in combining urethral play with other activities will appreciate the hollow design's practical advantages.
Avoid this if you have any urethral infections, recent piercings, or medical conditions affecting your urinary tract. The textured design creates more intense sensations than smooth plugs, so gauge your experience level honestly before committing to this advanced option.

While primarily a urethral device, The Undy's solid steel construction provides substantial weight that affects your entire genital area during wear. The mass creates downward pull that complements the internal sensations, making it popular among users who enjoy weighted accessories. This dual sensation profile bridges urethral and weight play categories.

Advanced users often combine urethral plugs with torso dolls for complete control scenarios. The secure positioning from the glans ring means vigorous activity with dolls won't dislodge this plug, while the internal stimulation adds another layer to extended play sessions. The combination creates comprehensive sensory overload.
The Undy completely redefined my expectations for hollow plugs. I've used plenty of straight designs, but those wavy ridges create completely different sensations—each one hits different nerve clusters as you insert. The 90mm length reaches deeper than most plugs I've tried, while that graduated 8-10mm sizing prevents the overwhelming stretch some wider options cause. What impressed me most was wearing it for over two hours during a session. The hollow core worked flawlessly, never creating blockages or discomfort. The steel construction adds serious weight that you feel with every step, and temperature play becomes addictive once you experience how long the metal holds heat or cold. Removal revealed just how much texture those waves provide—every ridge creates distinct pressure as it exits. This isn't a beginner's plug, but for experienced users wanting extended wear with serious internal stimulation, nothing matches it.
