What it is

Diamond Strap Silicone Penis Gag is a professional-grade BDSM restraint engineered for advanced power exchange. Built from medical-grade silicone with a genuine leather adjustable strap, it delivers complete oral restriction while maintaining safe breathing capacity. The diamond-shaped opening forces minimal mouth movement, creating both psychological tension and physical submission. Its secure, customizable fit works across different head sizes, making it reliable for intense scenes where verbal control is non-negotiable.

What sets this gag apart is its precision design—the diamond opening isn't arbitrary. It restricts speech while allowing the submissive to feel exposed and vulnerable, deepening the psychological surrender.

How to use a bondage gags and bit

Start by adjusting the leather strap to a comfortable baseline fit. Position the diamond-shaped opening inside your submissive's mouth, ensuring the silicone sits naturally without forcing their jaw open. Secure the strap firmly behind their head—tight enough to prevent removal, but not so tight it restricts breathing. Establish clear non-verbal communication signals (hand signals or dropping an object) before the scene begins, and check their breathing capacity throughout.

During your scene, monitor their reactions closely. The gag works best when combined with sensory restriction—blindfolds, restraints, or impact play intensify the psychological effect. Experiment with strap tightness to dial in the level of control that matches your dynamic. Many dominants pair this gag with Complete Bondage Sets to create layered restriction and deeper submission. Always maintain constant awareness of your submissive's state, and never leave them unattended while gagged.

Safety TIP

Care and storage

Clean Diamond Strap Silicone Penis Gag thoroughly with mild antibacterial soap and warm water after each use. Rinse completely to remove all soap residue, then air dry on a clean towel away from direct heat or sunlight. Store the gag in its included storage bag in a cool, dry place. Inspect the silicone and leather strap before each scene for cracks, tears, or wear. Use only water-based lubricants; silicone-based products can degrade the material.

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 →

I've used this gag extensively in my training sessions, and it never fails to break resistance. The diamond shape is deliberately designed—it forces the submissive into pure vulnerability while allowing safe breathing. I watch their eyes widen as I secure the strap, understanding immediately that their voice is now mine to control. The psychological shift is profound and immediate.

My technique involves gradual restriction. I start with light strap pressure, then increase intensity based on their reactions and body language. Pairing this gag with other restraints creates a comprehensive sensory experience—blindfolds, cuffs, or rope work together to deepen submission. Each submissive responds differently; some crave aggressive control from the first moment, while others need gentle introduction to silence.

What I observe is exquisite: the subtle movements, desperate attempts at communication, the raw surrender that comes when speech is removed. This gag is particularly effective with submissives who struggle to relinquish verbal control. By stripping away their voice, I force them into pure physical and psychological submission. The transformation is always remarkable.
