What it is

Tool Sound Black is a urethral sound built from high-grade platinum cure silicone for safe, precise internal stimulation. Its graduated diameter—starting at 0.51 cm and widening to 0.75 cm—allows controlled insertion and comfortable exploration. The textured grip gives you tactile feedback and command during use, while the flexible silicone conforms naturally to your body. This is a tool for experienced practitioners and those ready to explore deep sensory territories with intention and care.

What sets this sound apart is its engineering. Platinum cure silicone is non-porous, hypoallergenic, and heats quickly to body temperature, creating a seamless sensation. The 6.5-inch length provides sufficient reach without overwhelming. See the full BDSM Australia range of Penis Plugs to compare other urethral play options.

Key features

How to use a penis plug

Wash the sound thoroughly with antibacterial soap and warm water before use. Apply generous amounts of sterile, water-based lubricant to both the tip and your urethra. Begin insertion slowly, allowing the graduated diameter to guide you naturally. Never force; let gravity and steady pressure do the work. Breathe deeply and move at your own pace, exploring sensation without rushing.

Once inserted, you can experiment with subtle movements, temperature play, or pairing with external stimulation. Advanced users often combine urethral sounds with Electric Penis Pumps for intensified sensation. Always prioritize comfort and stop immediately if you experience sharp pain or discomfort.

Always use sterile, water-based lubricant generously; never force insertion; clean thoroughly with antibacterial soap or boil for sterilization before and after each use; do not share; stop immediately if you experience sharp pain. 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 Tool Sound Black with mild antibacterial soap and warm water after every use. For complete sterilization, boil for five minutes or soak in a 10% bleach solution. Rinse thoroughly and air-dry completely. Store in the provided bag away from direct sunlight and extreme heat. Use only water-based lubricants to preserve silicone integrity over time.

Mistress Athena's training notes

Tool Sound Black has become central to my dominance practice. The graduated diameter allows me to calibrate control precisely—I can read my submissive's tolerance through their breathing and muscle response. Insertion becomes a ritual of surrender, each millimeter a negotiation between my will and their vulnerability. The textured grip gives me tactile command; I feel exactly where the sound sits within them.

My submissives experience profound psychological shift when I introduce this tool. Anticipation precedes insertion—I describe each sensation before delivering it, building mental submission alongside physical exploration. Some require gentle coaxing; others respond to firmer direction. The sound becomes my extension into their most intimate territory, a conduit for complete power exchange.

Temperature play deepens the experience significantly. Cooling the sound before insertion creates exquisite contrast; warming it builds intensity. My dominance flows through this tool, and their surrender deepens with each careful movement. Aftercare is essential—this level of vulnerability demands reassurance and presence from me afterward.
