Instituted Cock Cage & Penis Plug Large

Chastity denial demands absolute control—but standard cages leave gaps in restraint. Instituted Cock Cage & Penis Plug Large combines lockable steel confinement with a deep urethral plug, giving you total command over a submissive's body and mind.

What it is

Instituted Cock Cage & Penis Plug Large is a high-performance steel chastity system engineered for experienced BDSM practitioners. The device pairs a lockable cage with a removable urethral plug, delivering dual-layer control that works on both physical and psychological levels. Crafted from 316L surgical-grade stainless steel, it's hypoallergenic, durable, and designed for extended wear. The six-ring open design balances breathability with comprehensive restraint, so a submissive remains aware of confinement without sacrificing comfort during longer sessions.

What sets this device apart is its integration of urethral play into the chastity experience. The 70mm plug transforms standard cage denial into deep sensory manipulation, intensifying psychological submission through constant, intimate awareness.

Every component is removable and adjustable, allowing you to scale intensity from teasing sessions to extended control scenarios.

How to use a male chastity

Clean the entire device thoroughly before use. Apply water-based lubricant generously to the urethral plug and cage interior. Insert the plug slowly into the urethra with steady, gentle pressure—never force it. Once positioned, carefully guide the cage around the penis and testicles, ensuring comfortable fit without pinching. Lock the cage securely if using the locking mechanism.

Start with shorter wear periods to allow your submissive to acclimate to the sensation. Gradually extend duration as their psychological tolerance builds. Monitor comfort levels closely, especially around the base and testicles. For advanced scenes, combine this cage with additional restraints like arm cuffs or collar work. Explore Electro Chastity Devices if you want to layer electrical stimulation into extended denial scenes. Always have a safety plan and maintain clear communication throughout wear.

Care and storage

Clean the cage and plug immediately after removal using medical-grade toy cleaner and warm water. Dry all components completely. For deep sterilisation, boil both pieces for 3–5 minutes or wipe with alcohol. Store in the provided bag away from direct sunlight and extreme temperatures. Inspect regularly for any signs of wear or damage before each use.

Mistress Athena's training notes

By Mistress Athena — professional dominant and kink educator, sole instructor behind BDSM Australia's library of training videos. Read her full bio →

This cage delivers exceptional psychological impact. Watching a submissive realise they've lost all control over their own body creates an immediate shift in power dynamics. The urethral plug amplifies that vulnerability—they become acutely aware of my dominance with every moment of wear. Cold steel against sensitive skin triggers visceral submission faster than almost any other tool.

My most effective approach is gradual conditioning. I begin with short sessions, building psychological tolerance before moving to extended wear. The removable plug allows me to adjust intensity based on individual response—some submissives respond to gentle, prolonged denial, while others require more aggressive control. By understanding these differences, I can tailor the experience to break through their resistance.

The six-ring design works brilliantly for long-term scenes. Breathability means submissives can wear this device for hours without physical breakdown, allowing their mental state to deepen. I've observed that the longer they're locked, the more readily they accept my commands. This cage becomes a tool for transformation, not just restraint.
