How to use a strap on sextoy

Start by adjusting the elastic harness to fit snugly but comfortably around your hips and thighs. Step into it as you would underwear, then secure the straps. Insert the dildo through the O-ring, ensuring it sits at the right angle for your intended use. Apply generous amounts of water-based lubricant to both the toy and your partner's opening. Go slowly on first insertion, allowing time for relaxation and arousal. Check in regularly and adjust positioning as needed for comfort and pleasure.

Once you're both ready, control your depth and rhythm based on feedback. The adjustable harness keeps the toy stable, so you can focus on connection and sensation. For extended scenes, the removable O-ring lets you swap toys without stopping. Explore different positions to find angles that work best for both of you.

Care and storage

Wash the dildo and harness with warm water and mild soap immediately after use. Air dry completely before storage. Store in a cool, dry place away from direct sunlight and heat sources. Keep the satin mask separate and store it in a clean, dry environment. Use only water-based lubricants with this toy; oil-based or silicone lubes can degrade the material over time.

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 →

This strap-on commands respect the moment a submissive sees it. Its substantial girth and length make psychological impact before physical sensation ever begins. My submissives understand immediately that they're entering a scene where control is absolute. The hollow design lets me observe their responses intimately—their breathing, tension, surrender—giving me real-time feedback on their mental state.

Positioning is everything. I use the adjustable harness to maintain perfect angles, never losing dominance or control. Some submissives require gradual introduction; others benefit from more aggressive assertion. The satin mask amplifies their vulnerability by removing visual cues, forcing them to trust completely. Sensation becomes their only reference point.

What I've learned is that this toy represents more than penetration—it's a tool for psychological transformation. Submissives often arrive expecting physical sensation and discover instead a profound experience of surrender. The removable O-ring allows scene variety without breaking intensity. My most effective training uses this toy strategically, never as punishment but as an instrument of control and obedience.
