Knot-Knot Silicone Urethral Sounds Kit By Nanma

Urethral sounding can feel intimidating without graduated tools to build comfort gradually. This kit provides three progressively sized sounds with textured and smooth options, letting you explore internal sensation safely at your own pace.

What it is

The Nanma Knot-Knot Silicone Urethral Sounds Kit Set is a three-piece urethral sounding set designed for gradual exploration of internal urethral sensation. Each sound features a stopper handle that rests against the urethral opening, preventing deeper insertion and providing secure grip control. The kit includes smooth surfaces for effortless gliding and textured beaded patterns that create tactile feedback as you insert and manipulate each sound. Body-safe silicone construction ensures non-porous, hygienic internal play without bacterial growth risk after thorough cleaning.

Graduated sizing eliminates the need to buy sounds separately—you progress from five to seven inches as your comfort and experience grow across multiple sessions. The flexible yet firm material maintains structural stability while guiding insertion smoothly.

Key features

• Graduated progression: Three sizes allow comfortable adaptation across sessions rather than jumping to larger dimensions immediately.
• Dual textures: Smooth shafts glide with minimal resistance; beaded patterns create stronger tactile sensation feedback during insertion and movement.
• Stopper handles: Built-in safety feature prevents over-insertion while providing secure grip control throughout use.
• Body-safe material: Non-porous silicone resists bacterial growth and remains hygienic with proper cleaning after each session.
• Complete kit: All three sounds arrive together with storage pouch and instruction guide, eliminating separate purchases.

Specifications

• Dimensions: Three pieces measuring five inches, six inches, and seven inches in length with graduated shaft diameters for progressive exploration.
• Material: Body-safe silicone that is non-porous, hygienic, and compatible with water-based lubricants for internal urethral use.
• Operation: Manual insertion and manipulation; no power source required for complete hands-on control over insertion pace and depth.
• Safety design: Stopper handles rest against urethral opening to prevent over-insertion; fully waterproof construction allows thorough cleaning.
• Package contents: Three graduated urethral sounds with stopper handles, discreet storage pouch, and detailed instruction guide for safe exploration.

How to use a urethral sound

Apply generous water-based lubricant to both the urethral opening and the sound's shaft before insertion. Position the stopper handle against the urethral opening and insert the sound slowly using controlled movements. Allow time for the urethra to adjust to the sensation before moving deeper or attempting any motion. Explore gentle thrusting or rotation only after full insertion and complete adjustment. Withdraw slowly and carefully with continued lubrication to minimize friction. Clean thoroughly with warm water and mild soap immediately after use.

Progress through the three sounds across multiple sessions rather than rushing through all pieces at once. Many users combine urethral sounding with external stimulation or masturbation to create blended sensation that feels more intense than single-point play alone. Advanced practitioners explore extended insertion sessions where the sound remains inside the urethra while engaging in other activities, building psychological arousal alongside physical sensation. Experiment with slight rotation or gentle thrusting once fully acclimated to each sound's dimensions. Some discover textured sounds create stronger sensation feedback than smooth versions; others prefer smooth shafts' gliding sensation.

Care and storage

Rinse the sounds under warm running water with mild soap immediately after use, paying attention to the stopper handle and textured areas where lubricant accumulates. Pat dry completely with a clean towel and store in the provided pouch in a cool, dry location away from direct sunlight. Water-based lubricant is compatible with silicone; avoid silicone-based lubes that degrade the material over time.

Urethral sounding offers unique internal sensation that many find profoundly arousing once they overcome initial nervousness. Graduated kits like this one make exploration accessible by removing the pressure to commit to a single sound before understanding your preferences.

Mistress Athena's training notes

By Mistress Athena — professional dominant and kink educator, sole instructor behind BDSM Australia's library of training videos. Read her full bio →

I have incorporated the Nanma Knot-Knot kit into my dominant practice for several years, finding it exceptionally effective for building psychological control through internal sensation play. Beginning with the smallest sound during initial training sessions, I watch my submissive's breathing patterns and facial expressions as the sound enters the urethra for the first time. Their body's response to the stopper handle's resistance reveals whether they experience pleasure, discomfort, or the fascinating space between both sensations. I control insertion and withdrawal pace entirely, using their reactions to determine how deeply I can push their boundaries during each session.

Submissives often enter a profoundly vulnerable state during urethral sounding, their psychological defenses lowering as they surrender control of such an intimate, sensitive area to my direction. This heightened receptivity deepens their obedience through verbal commands and reinforcement. The textured sounds create stronger psychological impact than smooth ones because submissives must concentrate intensely on the sensations, deepening their focus on my voice and commands. Pausing the sound at various depths while delivering instructions or punishments creates anticipation and reinforces their submission.

I have developed advanced techniques combining the Nanma kit with cock rings and penis plugs to create multi-layered control over my submissives. Beginning with the smallest sound while wearing a cock ring, I observe how external restriction and internal stimulation create a psychological state where submissives become entirely focused on my commands, their resistance completely dissolved. Extended training sessions where the submissive maintains insertion while performing other tasks under my direction create constant internal sensation that keeps them in a heightened submission state throughout the entire experience.

My submissives progress through predictable psychological stages during extended sounding sessions: initial nervousness, deepening arousal, complete psychological surrender, and finally profound obedience where they accept any command without hesitation. I deliberately time my most important training objectives for the moment when their psychological defenses are completely dismantled. Requiring submissives to insert and withdraw the sounds themselves while I provide verbal commands and criticism forces their active participation in their own domination. Tracking their comfort levels across sessions allows gradual introduction of longer insertion times and deeper penetration as their submission deepens and psychological boundaries expand under my training.
