Anal exploration requires trust, control, and the right tool. The Biird Anii Medium Size Borosilicate Glass Anal Plug delivers precision-engineered glass construction that makes insertion smooth, safe, and deeply satisfying for intermediate to advanced users.
The Biird Anii Medium Size Borosilicate Glass Anal Plug is a handcrafted glass toy engineered for advanced anal play. Its borosilicate glass construction is non-porous, hypoallergenic, and built to last. The smooth surface glides effortlessly with proper lubrication, while the transparent rainbow blue finish reveals every detail of the experience. Its ergonomic flared base ensures safe, controlled use.
What sets this plug apart is its dual capability for sensory play. The glass conducts temperature beautifully—warm it under hot water or cool it in the refrigerator to create intense thermal sensations. See the full BDSM Australia range of Glass Sex Toys to explore other borosilicate options for full-body sensory exploration.
Start by washing the plug thoroughly with warm water and specialized toy cleaner. Apply generous amounts of water-based lubricant to both the plug and your anus. Position the flared base outside your body, then use slow, steady pressure to guide the smooth glass inside. Let your body adjust to the sensation before moving deeper. Breathe slowly and relax into the experience.
Temperature play opens new dimensions of sensation. Warm the glass under hot running water or chill it in the refrigerator for 15 minutes before insertion. The thermal shift against sensitive tissue creates intense psychological and physical responses. Explore different positions to discover what feels right for your body. Incorporate Sex Games that build anticipation and control for deeper power exchange experiences.
Clean the plug immediately after use with warm water and toy cleaner, or run it through the dishwasher on a gentle cycle. For sterilization, boil the glass for 3–5 minutes or use a specialized glass toy sanitizer. Store it in the included vegan leather case to prevent dust accumulation and scratching. Keep it away from extreme temperature changes between uses.
Understanding your body and your boundaries makes every experience safer and more rewarding. Glass toys offer unique sensory possibilities that other materials cannot match. For deeper insight into pleasure, aging, and sexual exploration across all life stages, read Do Grannys Still Have Sex.
The Anii plug is exceptional for control work. When I introduce it to my submissives, the transparent glass lets me observe every micro-reaction—the slight tremor, the involuntary muscle contractions, the moment they surrender to sensation. Cold glass against sensitive skin creates an immediate visceral response that breaks through mental barriers faster than almost any other tool.
My most effective technique pairs slow, deliberate insertion with psychological manipulation. I describe exactly what will happen, building anticipation while holding complete control over depth, duration, and temperature. The transparency works powerfully in my favour—submissives know I'm watching every response, which deepens their sense of exposure and vulnerability.
Temperature variations keep them off-balance. Alternating between warm and cold glass creates unpredictable sensations that prevent adaptation. Advanced submissives who believe they can maintain composure crumble quickly under this precise, layered approach. The physical sensation combined with the knowledge that every reaction is being monitored and catalogued creates a profound psychological shift.
