Masters Series The Mortal Coil Sound delivers progressively building sensations through its graduated ridge system and carefully engineered swells. Constructed from temperature-responsive brushed stainless steel with a thru-hole design, this sound transforms urethral play into an escalating journey for experienced practitioners.

What It Does

Each ridge along the shaft creates distinct pressure points that stimulate nerve endings throughout the urethral passage. The progressive design means sensations build gradually—starting gentle and becoming more pronounced with deeper insertion. The stainless steel construction conducts temperature changes instantly, whether you prefer the shocking contrast of cold metal or the soothing warmth of heated steel.

The thru-hole design adds another layer of stimulation. Fluid can pass through the opening, creating unique internal sensations during use and climax. This hollow construction also enables creative temperature play—run cold or warm water through the opening to intensify thermal sensations against sensitive internal tissues.

Technical Specs

  • 6.63 inches total length, 5.13 inches insertable depth
  • Brushed stainless steel construction with mirror finish
  • Maximum diameter of 0.49 inches at widest point
  • Progressive ridge design with graduated swells
  • Complete thru-hole for fluid passage and temperature play

How To Use It

Sterilize completely before each session—this means boiling water, alcohol wipes, or UV sterilization. Use only sterile surgical lubricant designed for urethral play. Regular personal lubricants can introduce bacteria into sensitive areas. Start with the tapered tip, allowing your body to adjust to each progressive swell before advancing further.

Insert slowly and listen to your body's responses. The graduated design means you can control exactly how much stimulation you receive. Remove gradually—never pull out quickly. The ridged surface needs time to exit safely. Clean thoroughly with antibacterial soap immediately after use.

Who It Suits

This sound requires previous experience with urethral play. Beginners should start with smaller, smooth sounds before progressing to ridged designs. The 0.49-inch maximum diameter suits users comfortable with intermediate sizing. If you've never inserted anything into your urethra, this isn't your starting point.

Perfect for temperature play enthusiasts and those seeking textured internal stimulation. Users with steady hands and patience will appreciate the precision required for safe use. Avoid if you have any urinary tract infections, recent catheter use, or urethral scarring.

Where It Fits in Our Range

Head Job Strokers

While most strokers focus on external penis stimulation, urethral sounds like The Mortal Coil provide internal stimulation that complements external play. Many users combine sounds with strokers for layered sensations—the internal pressure from the sound enhances external stimulation.

Expert Review from Our In-House Tester

I've tested dozens of urethral sounds, but The Mortal Coil's progressive ridge system creates something entirely different. The first ridge slides in easily, giving me confidence to continue. By the third ridge at about 3 inches deep, the sensations shift from interesting to genuinely arousing. The 0.49-inch maximum diameter provides serious filling without being overwhelming. Temperature play works brilliantly—I chilled it for 10 minutes and the cold metal created shockwaves of sensation with each ridge. The thru-hole design means you can actually cum through it, which creates unique contractions around the steel. Not for nervous beginners, but experienced users will find this delivers exactly what advanced urethral play should feel like.
