What it is

The SONO No. 19 Dong Extension is a dual-purpose penis sleeve that extends your length by 35mm while delivering internal anal stimulation through an integrated butt plug. Crafted from soft, phthalate-free TPE, it stretches around your testicles and penis for a secure, comfortable fit. The curved plug is engineered to target the prostate, creating layered sensation during penetration.

What sets this extension apart is its unified design—you're not juggling separate toys. The 251mm sleeve length and attached anal component work together to create comprehensive stimulation. See the full BDSM Australia range of Penis Extenders to explore other enhancement options.

How to use a penis sleeves and extender

Apply water-based lubricant generously to your penis, testicles, and the butt plug. Stretch the ball strap carefully around your testicles, ensuring it sits comfortably without pinching. Slide your penis into the sleeve and position it for your desired fit. Slowly insert the curved butt plug, adding more lubricant as needed. Breathe steadily and relax your muscles to ease insertion.

Once positioned, experiment with different angles and movement speeds to discover what feels best. Your partner can also help guide insertion and adjust depth during play. For added versatility, explore Penis Pouches that offer alternative support and containment. Always communicate with your partner about comfort, and stop immediately if you experience sharp pain rather than pressure.

Always use water-based lubricant, clean the device thoroughly with mild soap after each use, insert slowly and breathe deeply to relax muscles, and never share the toy with partners who haven't been tested for STIs. 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 sleeve and butt plug with mild antibacterial soap and warm water immediately after use. Rinse completely and pat dry with a clean towel before storing. Keep it in a cool, dry place away from direct sunlight and heat sources. Store separately from other silicone toys, and use only water-based lubricants to preserve the TPE material.

Mistress Athena's training notes

This extension has become invaluable in my practice for psychological control. Watching a submissive surrender to dual penetration—external length and internal pressure simultaneously—creates a profound power dynamic. The device forces complete vulnerability; resistance becomes impossible. My submissives report feeling utterly possessed, which deepens their submission and trust in my authority.

I use this during advanced training sessions where psychological impact matters most. Slow insertion, deliberate pauses, and controlled depth adjustments allow me to orchestrate their emotional state. The curved butt plug provides exquisite leverage for demonstrating dominance without excessive force. Breathing work becomes essential—I guide each breath, turning the physical experience into a meditation on surrender.

Observation is everything. Muscle tension, pupil dilation, and voice changes tell me exactly when to increase pressure or pause. The device's design makes micro-adjustments possible, letting me keep my submissive on the edge of their limits. This precision is why it's become a cornerstone of my advanced protocol work.

See this and similar tools in action across my 300+ training videos on the BDSM Australia channel.
