What it is

The Kink Signature Plug is a hand-inserted anal toy engineered for progressive, comfortable stretch and fullness. Its spade-shaped silicone body tapers smoothly from tip to base, making insertion intuitive for both first-timers and experienced users. The flared base with Kink branding sits safely outside the body and simplifies removal. Doc Johnson built this plug from medical-grade silicone that's phthalate-free, hypoallergenic, and non-porous—meaning it cleans easily and won't harbour bacteria.

What sets this plug apart is its thoughtful engineering: the tapered design reduces insertion anxiety while the 1.5-inch diameter delivers satisfying fullness without overwhelming. See the full BDSM Australia range of Butt Plugs to compare sizes and styles. Premium silicone holds its shape, responds to body temperature, and lasts through years of use.

How to use a butt plug

Apply generous water-based lubricant to the plug and your anal opening. Breathe slowly and relax your muscles as you press the tapered tip gently inward. Go at your own pace—there's no rush. Once the widest point passes inside, the plug will settle naturally. Ensure the flared base stays outside your body, then adjust depth or position as comfort allows.

Wear the plug during other sexual activities to heighten sensation and deepen intimacy. You can combine it with vaginal penetration, manual stimulation, or bondage for layered sensation. Many people enjoy temperature play by warming or cooling the silicone before insertion. Explore wearing it during everyday activities if you're comfortable with that level of sensation. See the full BDSM Australia range of Butt Tails if you want to add visual appeal or extra sensation to your anal play.

Always use generous water-based lubricant, go slowly to avoid discomfort or injury, clean thoroughly with warm water and mild soap after each use, and never share the plug without cleaning it first. 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 with warm water and mild soap immediately after use. A dedicated toy cleaner works well too. Dry it completely with a soft cloth before storing. Keep it in a cool, dry place away from direct sunlight and extreme heat. Store separately from other silicone toys to prevent material degradation. Never use silicone-based lubricants, as they can damage the surface.

Mistress Athena's training notes

This plug serves my control beautifully. Watching submission unfold as I insert it—the breath catch, the tremor—tells me everything about my subject's readiness for deeper training. The smooth silicone glides past resistance, and that moment of surrender is where real psychological work begins.

I favour this design for its psychological weight. Once inside, it becomes a constant physical reminder of my authority. Commanding a submissive to wear it while performing other tasks—kneeling, serving, speaking only when permitted—amplifies their awareness of my power. The plug itself is almost secondary to what it represents: my control over their body and mind.

Different submissives respond in revealing ways. Some need only the anticipation; others require the full insertion and sustained wear to reach the headspace I'm training them toward. The flared base gives me easy control—I can adjust depth, remove it, or leave them suspended in that state of vulnerability. That flexibility is what makes this plug essential to my practice.
