What it is

Masters Series The Mortal Coil Sound is a precision urethral sound engineered for deep sensory exploration. Crafted from medical-grade stainless steel, it measures 6.63 inches overall with 5.13 inches of insertable length. The progressive swells create varying internal stimulation, while the integrated ring pull ensures safe control and retrieval during play. Smooth, polished surfaces and non-porous construction make insertion comfortable and sterilization straightforward.

What sets this sound apart is its thoughtful design for advanced users. The thru-hole feature enables enhanced sensation and easy cleaning, while stainless steel's natural temperature conductivity opens sensory play possibilities.

How to use a penis plug

Wash the sound thoroughly with antibacterial soap and warm water. Apply generous amounts of sterile water-based lubricant to the urethra and the sound itself. Insert slowly using steady, gentle pressure, allowing your body to adjust naturally to each stage. Pay close attention to your body's signals and stop immediately if you experience sharp pain or discomfort.

Advanced users can explore temperature variations by warming or cooling the sound before insertion. Experiment with different insertion depths to engage the progressive swells and create varied internal sensations. Combine with Penis Gags for layered sensory scenes. Movement should remain slow and controlled, with external stimulation introduced only when you feel fully comfortable and in control.

Always use sterile water-based lubricant, insert slowly and gently, and sterilize the sound by boiling or using a 10% bleach solution between uses; 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 thoroughly with antibacterial soap immediately after use. Sterilize by boiling for three to five minutes or soaking in a 10% bleach solution. Rinse completely under clean running water and dry with a lint-free cloth. Store in the provided protective pouch in a cool, dry place away from direct sunlight. Regular maintenance ensures safety and longevity.

Mistress Athena's training notes

Masters Series The Mortal Coil Sound has become an essential instrument in my practice. When introduced to a submissive, I watch their breath catch as awareness of vulnerability deepens. Control flows entirely through my hands—each millimeter of insertion, each pause, each subtle movement reminds them that their sensation exists only by my permission. The progressive swells amplify this dynamic, creating layers of stimulation I command completely.

Preparation is non-negotiable. My submissives learn to remain absolutely still, to surrender completely to the experience. The sound becomes a language of dominance, a way to push boundaries and deepen their understanding of submission. Some arrive trembling; others arrive eager. I calibrate their experience precisely, using the swells to take them to edges they did not know existed.

What distinguishes this sound is its precision. Stainless steel's weight and temperature conductivity create sensations beyond simple insertion. Advanced play incorporates temperature variation—warming the sound before introduction intensifies sensation dramatically. The thru-hole design proves invaluable during extended scenes, allowing me to maintain control while managing practical necessities. Aftercare remains essential; the intensity demands attention and reassurance afterward.
