Chasm Stainless Steel Cum-Thru Insert features hollow construction that delivers concentrated urethral stimulation with maintained natural function through its open channel design. The surgical-grade stainless steel provides temperature responsiveness and complete sterilization capability, secured with a ball stopper for confident extended wear during intense sounding sessions.

What It Does

The hollow core creates a unique dual sensation where you feel both the internal pressure of insertion and the natural flow when you climax or urinate without removal. As you move, the steel shifts subtly inside your urethra, creating focused friction along nerve pathways that standard solid plugs miss entirely. The narrow 0.10-inch diameter concentrates sensation precisely where it matters most.

Temperature play enhances this insert completely—chill it in cold water for sharp contractions that make your dick hypersensitive, or warm it gently for relaxing pressure that lets you wear it longer. The stainless steel holds temperature exceptionally well, maintaining the sensation you choose throughout your session.

Technical Specs

  • Total length: 2.5 inches with 2 inches insertable
  • Diameter: 0.10 inches (2.54mm) precision bore
  • Material: Medical-grade stainless steel, fully sterilizable
  • Design: Hollow core with ball stopper safety feature
  • Care: Boilable, autoclavable, bleach-safe cleaning

How To Use It

Clean both yourself and the insert thoroughly, then use sterile lubricant specifically designed for urethral play. Insert slowly, letting your urethra adapt to the steel's presence—the ball stopper will prevent over-insertion automatically. The hollow design means you'll feel immediate internal pressure that's different from solid plugs, more like controlled expansion than simple stretching.

Once positioned, you can wear it during masturbation or leave it in place for extended sessions. The open channel lets you function normally when needed, while movement during arousal creates shifting sensations that build gradually. Remove slowly after play, cleaning immediately to maintain hygiene standards essential for urethral toys.

Who It Suits

Perfect for sounding enthusiasts who want functional versatility beyond basic stimulation. If you enjoy longer sessions or need the option to climax without removal, this hollow design solves practical concerns while intensifying sensations. The narrow diameter suits both newcomers to metal sounds and experienced players who prefer focused rather than stretched sensations.

Avoid if you have any urinary tract issues, infections, or haven't mastered basic sounding safety. This requires absolute cleanliness and understanding of proper insertion techniques. Not suitable for rough play or sharing between partners without complete sterilization.

Where It Fits in Our Range

E Stim Kits

While primarily a mechanical sound, the Chasm's conductive stainless steel makes it compatible with electrical play when used with appropriate e-stim units. The hollow design allows current flow while maintaining internal contact for unique electro-urethral experiences that solid plugs cannot deliver.

Ribbed Penis Plugs

Unlike textured plugs that rely on surface ridges, the Chasm creates sensation through internal pressure and hollow function. It bridges the gap between basic smooth sounds and complex ribbed designs, offering intensity without aggressive texturing that some find overwhelming during extended wear.

Expert Review from Our In-House Tester

The Chasm delivered sensations I hadn't experienced with solid sounds—there's this constant awareness of internal space that's both filling and open simultaneously. After warming it to body temperature, the 2-inch insertion felt completely natural within minutes. What struck me most was how the hollow design changed everything about climaxing; instead of removal being necessary, the open channel created this intense focused release that felt amplified by the steel's presence. The ball stopper provided reassurance during deeper exploration, letting me focus entirely on sensation rather than safety concerns. Temperature play worked exceptionally well—chilling it created sharp contrasts that made even light movement incredibly intense. The narrow diameter concentrated stimulation precisely without the overwhelming stretch of wider plugs.
