Mortal Coil Sound by BDStyle

Urethral play demands precision, control, and deep trust. The Mortal Coil Sound delivers all three—a medical-grade stainless steel sound engineered for experienced users who want intense, focused stimulation with every insertion.

What it is

Mortal Coil Sound is a precision urethral sound crafted from medical-grade stainless steel. Its 15 cm length and gradually increasing diameter create a controlled insertion experience designed for advanced users. The textured surface—featuring strategically placed ridges and balls—delivers intense sensory feedback with every movement. A 2.7 cm glans ring at the base provides additional stimulation and helps secure positioning during play.

This sound stands apart through its meticulous engineering: each ridge is placed to maximize sensation while maintaining safety for experienced practitioners. Unlike generic sounds, the Mortal Coil Sound demands skill and focus from its user, making it ideal for those who understand urethral anatomy and respect the sensitivity involved.

How to use a penis plug

Sterilize your hands and the sound thoroughly before beginning. Apply generous amounts of sterile, water-based lubricant to both the sound and your urethral opening. Position yourself comfortably and relax completely. Slowly guide the sound inward, allowing gravity and your own relaxation to aid insertion—never force it. Pause if you feel sharp pain; mild sensation is normal. Once fully inserted, the glans ring sits at your base, anchoring the sound in place.

Experiment with gentle movements, slight angles, and varying depths as your experience grows. Controlled breathing helps manage sensation and maintain focus. Some users combine sound play with external stimulation or incorporate it into broader sensation scenes. Always withdraw slowly and carefully, clean immediately afterward, and allow time for your urethra to return to normal.

Care and storage

Clean the Mortal Coil Sound immediately after use with mild antibacterial soap or specialized toy cleaner and warm water. For complete sterilization, boil for five minutes in clean water. Dry thoroughly with a lint-free cloth to prevent water spots on the stainless steel. Store in the provided protective case away from direct sunlight and extreme temperatures to maintain the finish.

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 →

The Mortal Coil Sound has become essential in my advanced training protocols. Its precision allows me to create moments of exquisite control—watching my submissives surrender to sensation as I guide the sound inward. The textured ridges deliver exactly the intensity I choose, making it a tool of psychological dominance as much as physical sensation. I observe their breathing shift, their vulnerability deepen, and their trust crystallize in real time.

My technique involves meticulous preparation: mental conditioning, relaxation protocols, and absolute focus on my submissive's state. Insertion becomes a ritual of power exchange where they relinquish control to my hands and my knowledge. The glans ring provides a visual anchor—a constant reminder of their submission. Each session teaches them the difference between pain and sensation, between resistance and surrender.

What makes this sound invaluable is its demand for skill. It cannot be rushed or improvised. My submissives understand that I've invested time in mastering this tool, and that knowledge itself becomes part of their psychological submission. Advanced play with the Mortal Coil Sound is never about the object—it's about the trust required to place oneself entirely in another's hands.
