Urethral play demands precision, control, and absolute safety. Depth Charge Sound Black delivers all three—a medical-grade silicone sound with 13 graduated bumps that lets you explore intense sensation at your own pace, with confidence.
Depth Charge Sound Black is a urethral sound engineered for controlled, progressive exploration. Built from medical-grade silicone, it features a flexible shaft with 13 strategically placed bumps that deliver escalating stimulation to the sensitive nerve endings of the urethra. The graduated design lets you start shallow and move deeper as comfort and arousal allow. An ergonomic 3 cm handle gives you precise control over insertion depth and movement, making every sensation intentional.
What sets this sound apart is its balance of accessibility and intensity. The bumps aren't random—they're positioned to build sensation progressively, so beginners can explore at their own rhythm while experienced users can push further. See the full BDSM Australia range of Urethral Sounds for other options in this category.
Clean the sound thoroughly with warm water and mild soap before use. Apply generous amounts of water-based lubricant to the shaft and your urethra. Relax completely, breathe slowly, and gently guide the tip into the urethra. Use the handle to control insertion depth—start shallow and pause to adjust to the sensation before moving deeper.
Movement should be slow and deliberate. Experiment with gentle rocking motions to activate the bump textures, or try slight twists to vary stimulation. Pay attention to your body's responses and never force insertion. For those interested in progressive stretching, the Urethral Stretcher collection offers complementary tools designed to work alongside sounds. Always use water-based lubricant—silicone lubricant can degrade the material.
Wash with warm water and mild soap immediately after use. For deeper sterilisation, boil the sound for 3–5 minutes or use a dedicated toy steriliser. Store in the provided fabric pouch in a cool, dry place away from direct sunlight and heat. Never use silicone-based lubricants, as they can damage the material. Keep separate from other toys to prevent cross-contamination.
Urethral play is a skill that deepens with knowledge and patience. Understanding anatomy, proper technique, and safety protocols makes every session more rewarding. Read our detailed guide, How To Use A Urethral Dilator, for step-by-step instruction and expert safety advice.
Depth Charge Sound Black is my instrument of precision control. The graduated bumps allow me to calibrate sensation with exact intent—I build anticipation slowly, watching my submissive's responses shift as each bump passes deeper. Eye contact during insertion amplifies the psychological surrender; they're not just feeling the sound, they're feeling my dominance through it.
What I've observed is that this tool transforms power exchange into something visceral. Restraint amplifies the effect—when a submissive cannot move or touch themselves, the sound becomes everything. I use shallow insertion as a teasing technique, holding them at the edge of deeper sensation before deciding whether to advance. The flexibility of the silicone lets me adjust angles unexpectedly, keeping them off-balance.
Combining this sound with denial protocols creates profound psychological impact. A submissive denied orgasm while experiencing the Depth Charge's sensations enters a state of complete focus on my control. The bumps become a language between us—each one a small reminder of who holds power in the scene. Recovery and aftercare matter as much as the sensation itself; I always ensure they return to baseline safely.
