What it is

The Be Strong 7.5in Slim Dong 2 Pc Hollow Silicone Strap-On Set is a complete harness system designed for couples and individuals exploring penetrative play together. The hollow silicone dong measures 7.5 inches with a slim diameter, making it comfortable for varied body types and insertion techniques. The adjustable harness accommodates waist sizes from 28 to 48 inches, so fit is never a guessing game. Medical-grade silicone means the toy is body-safe, non-porous, and built to last through regular use.

What sets this system apart is its straightforward two-piece design and genuine adjustability. You're not buying a one-size-fits-most harness; you're buying flexibility and control. See the full BDSM Australia range of Strap-On-Me for other harness and dong combinations.

How to use a strap on sextoy

Start by adjusting the harness to fit snugly around your waist—it should feel secure but not restrictive. Apply water-based lubricant generously to both the dong and the receiving partner's vagina or anus. Begin with slow, shallow penetration to allow comfort and arousal to build. Communicate constantly; let your partner guide the depth and pace until you both find a rhythm that feels good.

Once you're both settled, you can experiment with different angles, speeds, and positions to discover what works best. The adjustable harness keeps the dong stable throughout. Explore how the Sensuva On Sensuva On range pairs with harness play for added sensation. Always check in with your partner, go slowly when trying something new, and remember that comfort and consent drive everything.

Use plenty of water-based lubricant, go slowly, and stop immediately if there's pain; never share without thorough cleaning between partners. 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 dong and harness with warm water and mild antibacterial soap after every use. Rinse thoroughly and air dry completely before storing. Keep both pieces in the provided storage bag, away from direct sunlight and heat. Store water-based lubricant separately to avoid any contact with the silicone that might degrade it over time.

Mistress Athena's training notes

This strap-on's hollow design gives me precision control in my scenes. The slim profile lets me adjust intensity with deliberate, calculated movements—each thrust a statement of dominance. My submissives feel the psychological weight of the harness, knowing they're completely vulnerable to my pace and depth. Watching them surrender to the sensation, knowing I control every moment, is where the real power lives.

The adjustable harness means I can wear it for extended scenes without discomfort, which matters when you're focused on your submissive's response rather than your own body. I've found the hollow design particularly useful for sensory play—temperature changes, textures, the psychological anticipation of what's inside. My submissives often break faster when they can't predict what's coming.

Different submissives require different approaches. Some need gentle, sustained pressure to build trust; others respond to sudden intensity shifts. This strap-on's versatility lets me tailor each scene to the individual. The quality of the silicone means I can use it session after session without degradation, which keeps my scenes consistent and controlled.
