Anal play demands confidence and comfort—two things many people struggle to find together. The Master Series Dark Invader Metal & Silicone Anal Plug Medium combines a weighted metal core with a secure silicone base, giving experienced users the substantial sensation they crave without compromise.
The Master Series Dark Invader Metal & Silicone Anal Plug Medium is a hybrid toy that merges the sensory depth of weighted metal with the comfort and safety of body-safe silicone. Its tapered aluminum alloy core delivers substantial internal pressure while the flared silicone base sits securely between the cheeks, preventing unwanted movement during wear. The metal responds to temperature play, letting you warm or cool the surface for dynamic sensation.
This design bridges the gap between traditional plugs and advanced anal toys. The nickel-free aluminum is non-porous and durable, while the medical-grade silicone offers flexibility without compromise. See the full BDSM Australia range of Butt Plugs to compare options and find your ideal fit.
Start by washing the plug thoroughly with antibacterial soap and warm water. Apply a generous amount of water-based lubricant to the tapered tip—this reduces friction and makes insertion smooth and comfortable. Relax your body and breathe steadily, then slowly guide the metal tip toward your anus. Allow the sphincter to open gradually as the taper widens. Once fully inserted, the silicone base will rest securely against your body.
Wear the plug for as long as feels good, starting with shorter periods if you're new to this size. You can experiment with temperature by running the metal under warm or cool water before insertion. For deeper exploration, try wearing it during other activities to discover how the weight enhances sensation. If you're concerned about stability during movement, explore Tunnel Plugs as an alternative option that offers different base designs.
Wash the plug with mild antibacterial soap and warm water after each use. Rinse completely to remove all soap residue, then pat dry with a clean towel. Store it in the provided pouch in a cool, dry place away from direct sunlight and extreme temperatures. Avoid harsh chemicals or abrasive scrubbers that could damage the silicone. With proper care, this toy will remain safe and reliable for years.

The Dark Invader has become essential to my protocol work. Its weighted presence creates an undeniable internal sensation that keeps my submissives grounded in the moment. Metal and silicone combine to deliver both comfort and intensity—a rare balance. I use it to deepen focus, teaching my submissives to accept sensation without resistance.
Insertion is deliberate and controlled. I direct each movement, watching for signs of surrender as the tapered tip opens them slowly. The weight becomes a constant psychological anchor, reminding them of my authority throughout the session. Temperature play adds another layer—warming the metal before insertion intensifies sensation and deepens their mental state.
Extended wear teaches patience and acceptance. My submissives learn to breathe through discomfort, transforming physical sensation into mental discipline. The flared base keeps the plug secure, so they remain aware of it without distraction. This tool has proven invaluable for breaking down resistance and building trust through controlled vulnerability.
