Urethral sounding takes a particular kind of curiosity – and the Master Series Mortal Coil Sound is built to reward it. Shaped with progressive swells along a long, smooth stainless steel shaft, it delivers targeted internal stimulation that builds gradually as you go deeper.
The brushed stainless steel construction gives the Mortal Coil a satisfying weight and a silky-smooth surface that glides with ease. It also makes temperature play effortless: warm it under hot water for a gentle heat, or pop it in the refrigerator for a cool, contrasting sensation. Either way, the difference is immediate and intense.
Design details that make a difference
A thru-hole runs the full length of the shaft, and a ring pull is attached at the end for confident, controlled manipulation and easy retrieval. These aren’t just convenience features – they’re there for safety and peace of mind. The progressive swells mean you can work at your own pace, pausing wherever the sensation feels right.
