What it is

The Undy Waved Hollow Penis Plug is a carefully engineered urethral toy built from medical-grade surgical steel. Its 105 mm length and 93 mm insertable depth suit intermediate to advanced users exploring urethral play. The waved, ribbed surface delivers intense nerve stimulation, while the hollow design enables fluid play for those ready to explore that dimension. Its flared safety disc prevents unwanted slippage, giving you confidence during use.

What sets this plug apart is the precision of its construction and its dual purpose—the waved texture provides powerful internal sensation, while the hollow channel opens new possibilities for experienced users.

How to use a penis plug

Start by washing the plug thoroughly with mild soap and warm water. Apply generous water-based lubricant to both the plug and your urethra. Relax, breathe steadily, and slowly guide the plug inward, pausing as needed to let your body adjust to the waved texture. Stop immediately if you feel sharp pain—discomfort means slow down or stop.

Once inserted, you can experiment with different positions to discover where the ribbed surface delivers maximum sensation. Experienced users explore the hollow design's potential through fluid play. Combine this plug with Penis Pouches for layered sensation and extended wear. Always clean thoroughly after use and store in the included bag.

Safety tip

Use plenty of water-based lubricant, insert slowly, and stop immediately if you experience sharp pain or difficulty—never force the plug, and clean it thoroughly before and after each use. Safety first. This information is general in nature only and is not medical or professional advice; it does not account for your individual circumstances. Discontinue use immediately if you experience pain, numbness, discolouration, irritation or discomfort, and seek advice from a qualified medical professional if you have a relevant health condition or if symptoms persist.

Care and storage

Clean the plug with mild soap and warm water or a specialized toy cleaner after every use. Dry it completely with a soft cloth before storing. Keep it in the included storage bag away from direct sunlight and extreme temperatures. Water-based lubricant is your only choice—oil and silicone lubes can damage the steel surface over time.

Mistress Athena's training notes

This plug has become essential in my control work. When I introduce it during a scene, my submissive's entire focus narrows to the sensations I'm orchestrating. The waved texture creates exquisite psychological tension—they're hyperaware of each ribbed section as it slides deeper. Their breathing changes, their composure fractures, and I watch them surrender to sensation they can't escape.

The hollow design gives me remarkable control over their experience. I can manipulate sensation, introduce temperature play, or demonstrate complete dominance through this single tool. Submissives who arrive believing they can maintain stoicism under any circumstance quickly learn otherwise. The plug's flared safety disc means I can leave them wearing it for extended periods, building psychological impact without physical risk.

What I've learned using this plug is that urethral play isn't primarily physical—it's psychological. The intimacy of controlling their most sensitive responses, the vulnerability they must surrender to my direction, the trust required when they cannot see or fully predict what comes next—these create profound power exchange. This plug delivers all of that.
