Firefly - Ace I by NS Novelties

Anal play can feel intimidating or visually monotonous. The Firefly - Ace I transforms that experience with light-activated glow technology built into premium body-safe silicone, adding visual intrigue and psychological intensity to every moment.

What it is

The Firefly - Ace I is an anal plug engineered around a single bold idea: glow-in-the-dark technology that activates with light exposure, creating an ethereal visual effect during intimate moments. The plug itself is carved from premium body-safe silicone, hypoallergenic and non-porous, with a curved base that seats securely and comfortably. Its smooth surface glides easily and responds to touch, while the phosphorescent pigments embedded throughout the material produce that signature luminescent effect without batteries or electrical components.

What sets it apart is the marriage of psychological theatre and physical design. The glow transforms a private moment into something almost ritualistic—a visual anchor that heightens anticipation and sensory awareness. The size and shape work for both newcomers and experienced users. See the full BDSM Australia range of Butt Plugs to compare other options.

How to use a butt plug

Charge the plug's luminescent properties by exposing it to ambient light for several minutes before use. Apply generous amounts of water-based lubricant to both the plug and your anus. Begin insertion slowly, using the curved base as your guide. Relax and allow your body to adjust to the sensation. Once fully inserted, adjust positioning until you find maximum comfort and stimulation. The smooth silicone surface makes insertion straightforward and pleasurable.

Experiment with different lighting conditions to discover how the glow intensifies or fades, creating varied visual experiences. Wear the plug during foreplay, solo exploration, or combined with other activities. Low-light environments maximise the luminescent effect and heighten sensory engagement. Explore additional options like Butt Tails to expand your anal play repertoire. Always listen to your body and remove the plug if you experience pain or discomfort.

Care and storage

Wash the plug with mild antibacterial soap and warm water immediately after use. Dry it completely with a soft cloth before storing. Keep it in the provided storage bag away from direct sunlight for extended periods, as prolonged sun exposure may eventually fade the luminescent properties. Store in a cool, dry place away from extreme heat or cold. Inspect regularly for any signs of wear or damage.

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 →

The Firefly - Ace I has become an essential control instrument in my practice. Watching my submissives respond to the glowing effect creates a psychological intensity that far exceeds simple physical sensation. The luminescence transforms the experience into theatre—a visual anchor that deepens their submission and heightens their vulnerability. Each glow cycle becomes a moment of anticipation and surrender.

I employ this plug strategically during training scenes to demonstrate complete dominance. The light-activated glow allows me to create surprise moments—adjusting lighting to intensify or diminish the effect, keeping my submissive in a state of heightened awareness. Submissives often become transfixed by the glowing effect, which makes them more receptive to direction and more focused on my commands. The psychological impact is far more potent than the physical sensation alone.

The curved base ensures secure placement during extended wear, allowing me to focus entirely on mental control rather than worrying about the plug shifting. The silicone's smooth finish and responsive texture make it ideal for demonstrating my complete authority over their body. I've found it particularly effective with submissives who have visual kinks, as the glow creates an almost ritualistic, hypnotic quality to the power exchange.
