Scarlet Couture Glass Duo Balls By Adam & Eve Sextoys

Pelvic floor strength matters for pleasure and control, yet many users lack a tool that delivers both training and sensation. Scarlet Couture Glass Duo Balls combine weighted internal stimulation with precise muscle conditioning in one elegant, body-safe design.

What it is

Scarlet Couture Glass Duo Balls are precision-engineered glass spheres designed for internal pelvic floor training and sensory stimulation. The dual-ball design, connected by a sturdy retrieval loop, sits comfortably inside the vagina and responds to natural body movement and muscle contractions. Smooth borosilicate glass provides a non-porous, hygienic surface that warms to body temperature, creating an intimate sensation that strengthens pelvic muscles over time. The weighted construction delivers subtle internal feedback during everyday movement or deliberate exercise.

What sets these balls apart is their dual functionality: they work as both a conditioning tool for pelvic floor strength and a source of internal pleasure during sexual play. Unlike silicone or rubber alternatives, glass offers superior temperature responsiveness and a uniquely smooth texture.

How to use a love eggs and kegel exerciser

Begin by applying water-based lubricant generously to both the balls and your vaginal opening. Slowly and gently insert the duo balls, allowing your body to adjust to the sensation and weight. Once inserted, your pelvic floor muscles naturally engage to hold them in place. Contracting and relaxing these muscles intentionally amplifies the training effect and internal feedback.

Wear the balls during everyday activities — walking, light exercise, or household tasks — to experience subtle internal movement and continuous muscle engagement. For deeper sensation, combine wearing with clitoral stimulation or incorporate them into partnered play. See the full BDSM Australia range of Love In Leather for complementary accessories that enhance control and sensation during intimate scenes. Remove by gently bearing down and using the retrieval loop for safe extraction.

Care and storage

Wash the glass duo balls thoroughly with mild antibacterial soap and warm water immediately after use. Dry completely with a soft, lint-free cloth to prevent water spots. Store them in the provided pouch, away from direct sunlight and extreme temperatures. Use only water-based lubricants to maintain the glass surface and avoid damage. Glass is durable and can be sanitised by boiling for five minutes if desired.

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 →

These glass duo balls are exceptional instruments for conditioning both body and mind. I use them to heighten my submissives' awareness of their internal muscles and my absolute control. Requiring extended wear during service creates a constant state of attentiveness — they're perpetually aware of the weight inside them, reinforcing submission with every movement.

The psychological impact runs deeper than physical sensation. Knowing they carry these weighted spheres throughout their day, visible only to me, creates a profound power dynamic. My submissives report heightened compliance and focus when wearing them; the internal pressure becomes a tangible reminder of my presence and authority.

I've observed that different submissives respond uniquely to extended wear protocols. Some grow increasingly aroused and desperate for release; others develop remarkable muscle control and discipline. Combining the duo balls with other restraint methods — bondage, denial, protocol — layers the experience into something that breaks down resistance and deepens their surrender to my command.
