Key features Adjustable harness system: Precise tension control lets you increase intensity gradually or hold submissives in sustained discomfort during extended scenes.

Medical-grade silicone: Non-porous, hypoallergenic surface that's smooth for insertion and simple to sanitise between uses. Tapered tip design: Ergonomic entry point allows comfortable insertion for those new to anal training while delivering substantial internal stimulation. Substantial girth: 1.5-inch diameter provides meaningful sensation without excessive size, ideal for intermediate practitioners building tolerance. Specifications Total length: 4 inches; insertable depth 3.5 inches Maximum diameter: 1.5 inches Weight: 120 grams Material: 100% medical-grade silicone, phthalate-free, non-porous Power: Manual operation; no batteries required Lubrication: Water-based lubricants only Included: SONO No. 8 Butt Plug 4 Inches, adjustable harness, cleaning instructions, storage bag How to use a butt plug Preparation is essential. Apply water-based lubricant generously to both the plug and your anal opening. Begin with the tapered tip, using slow, deliberate pressure. Insert gradually—rushing causes discomfort and breaks trust. Once fully seated, adjust the harness to your preferred tension. The slave bell should hang naturally, positioned to create sound with any movement. During extended wear, monitor your submissive's physical and psychological state. The harness allows you to increase tension incrementally, deepening submission over time. Pair this plug with restraints, sensory deprivation, or verbal commands to amplify control. For those exploring cock plugs alongside anal training, Pee Thru Cock Plugs create complementary sensations during complex scenes. Always use water-based lubricant and never force insertion. Use generous water-based lubricant, insert slowly and never forcefully, clean thoroughly after each use with mild soap, and establish clear communication with your partner about comfort and boundaries. 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 Clean the plug immediately after use with mild antibacterial soap and warm water. Rinse completely to remove all soap residue. Pat dry with a clean towel or allow to air dry fully. Store in the provided bag away from direct sunlight and extreme heat. Water-based lubricant only—oil and silicone lubes damage the material. Inspect regularly for tears or degradation.

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 SONO No. 8 Butt Plug 4 Inches has become indispensable in my practice. Its adjustable harness delivers precise control that transforms a simple toy into a complex training instrument. I watch my submissives respond to the slave bell—that auditory awareness creates psychological tension far beyond the physical sensation. Some tremble with anticipation; others freeze, terrified of making noise. My most effective technique pairs this plug with sensory deprivation. Blindfolded and silent, my submissive cannot predict when I'll adjust the harness or shift their position. The bell becomes a betrayer—any involuntary reaction exposes them. I use verbal commands to deepen this psychological layer, asking them to describe exactly what they feel. This vulnerability builds obedience faster than impact play alone. Newer submissives benefit most from this plug's design. The tapered tip allows gradual introduction to anal training without overwhelming them. Over successive sessions, I incrementally increase harness tension, building both physical tolerance and psychological submission. The silicone's smoothness means they can focus entirely on the sensations and power dynamics rather than discomfort. By the third or fourth session, they're ready for more advanced techniques. See this and similar tools in action across my 300+ training videos on the BDSM Australia channel.
