What it is

This comprehensive kit comprises five medical-grade silicone urethral sounds engineered for safe, progressive exploration. Each sound features a nail-shaped design that facilitates smooth insertion while maintaining structural integrity. Graduated sizing allows you to start small and advance at your own pace, building comfort and control with every use.

The kit is built for advanced users who understand the importance of precision and preparation. Medical-grade silicone ensures complete body compatibility and full sterilisation capability. See the full BDSM Australia range of Urethral Sounds to explore other options in this category.

How to use a urethral sound

Sterilise your chosen sound with medical-grade solution before every use. Apply generous water-based lubricant to both the sound and your urethral opening. Insert the smallest size slowly, allowing your body to relax. Breathe steadily and stop immediately if you experience sharp pain or discomfort.

As you gain experience, progress to larger sizes only when you feel ready. Never force insertion or rush progression. Combine sounds with Urethral Stretcher techniques once you have developed solid foundational skills. Always prioritise your comfort and listen to your body's signals throughout the experience.

Always use generous water-based lubricant, sterilise before and after each use with medical-grade solution, begin with the smallest size, and never force insertion or progress faster than your body allows. 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

After each session, wash thoroughly with warm soapy water, then sterilise using an autoclave or medical-grade high-temperature cleaning solution. Store all sounds in the provided case away from direct sunlight and extreme temperatures. Use only water-based lubricant to preserve silicone integrity. Check surfaces regularly for any signs of wear or damage before use.

Mistress Athena's training notes

This kit has become essential in my advanced protocols. The graduated sizing allows precise control over my submissives' sensory experiences, starting small and building intensity only as I decide. Medical-grade silicone provides an exceptional psychological tool—the clinical precision mirrors the power dynamic itself.

Observation is everything. I watch breathing patterns shift with each millimetre of insertion, noting how their mental state transforms from anticipation to surrender. The nail-shaped design offers smooth progression that feels inevitable, unstoppable. Combined with restraint, this kit becomes an instrument of absolute dominance.

Temperature play elevates the experience further. Warming or cooling each sound before insertion creates sensory unpredictability my submissives cannot control. Their vulnerability deepens with every exchange of sizes. The psychological surrender is what truly matters—the physical sensation merely amplifies it.

See this and similar tools in action across my 300+ training videos on the BDSM Australia channel.
