What it is

California Exotics Expandable Silicone Inflatable Butt Plug is an advanced anal toy built around one core idea: you control the size. Made from medical-grade silicone with a phthalate-free PVC inflation system, it starts at 3 inches and expands gradually as you pump the included hand bulb. The flanged base keeps it stable, and the quick-release valve lets you deflate instantly if you need to. This level of precision sets it apart from fixed-size plugs—especially for users who want to explore their limits safely.

The engineering here matters. Every component is designed for hygiene and durability. See the full BDSM Australia range of Butt Plugs to compare styles and materials. What makes this one different is the inflation mechanism itself: it turns a moment of vulnerability into a moment of power, because you—not the toy—decide how far to go.

How to use a butt plug

Apply water-based lubricant generously to both the plug and your anus. Relax and breathe deeply as you slowly insert the uninflated plug. Once positioned comfortably, attach the pump hose and begin inflating in small increments. Pause between pumps to let your body adjust. Stop when you reach your desired fullness—there's no rush and no target size. If sensation becomes too intense, press the quick-release valve to deflate immediately.

During partnered play, communication is essential. Let your partner know your comfort level before starting, and establish a clear signal if you need deflation. Some users enjoy gradual expansion during foreplay; others prefer maximum inflation during climax. Pair this plug with Butt Tails for added visual or tactile sensation. Always prioritize your body's signals over any expectation of performance.

Use plenty of water-based lubricant, inflate slowly and listen to your body, and deflate immediately if you experience sharp pain or numbness. Safety first. This information is general in nature only and is not medical or professional advice; it does not account for your individual circumstances. Discontinue use immediately if you experience pain, numbness, discolouration, irritation or discomfort, and seek advice from a qualified medical professional if you have a relevant health condition or if symptoms persist.

Care and storage

Wash the plug and hose with mild antibacterial soap and warm water after every use. Rinse thoroughly and air-dry completely before storing in the provided bag. Avoid silicone-based lubricants, which can degrade the material. Check the silicone and valve regularly for cracks or wear. Store in a cool, dry place away from direct sunlight to preserve the silicone's integrity.

Mistress Athena's training notes

This device has become one of my most valued instruments for teaching submission. I watch carefully as I inflate it—observing how my submissive's breathing changes, how their muscles tense and release. The gradual expansion creates a profound surrender that rigid plugs simply cannot achieve. Control flows directly from my hands through the pump into their body, a tangible expression of power exchange.

Psychological training happens here in layers. The anticipation of expansion triggers vulnerability. The inability to predict the next pump stroke keeps them mentally present and focused entirely on my direction. My most disciplined submissives learn to welcome the sensation as proof of their obedience, transforming discomfort into devotion.

The quick-release valve serves a purpose beyond safety—it's a teaching tool. When I demonstrate that I can deflate instantly, my submissive understands that their wellbeing matters to me, that control is always paired with care. This builds the trust necessary for deeper scenes. The silicone's smooth surface and the hose system's precision make this plug ideal for extended wear during training sessions.
