B Balls Purple/White by Fun Factory

Anal pleasure toys often feel one-dimensional. The Fun Factory B Balls Purple/White uses rotating internal weights that activate with your movement, delivering continuous, dynamic stimulation without batteries or buttons—a genuinely different experience.

What it is

Fun Factory B Balls Purple/White is a dual-weighted anal toy engineered in Germany using precision-crafted rotating spheres inside medical-grade silicone. The two spheres—one smaller, one slightly larger—sit connected by a tapered tip and a comfortable retrieval base. Internal weights respond to body movement, creating continuous stimulation that shifts and changes as you move, sit, or walk. No manual control needed; the toy does the work for you.

What sets this toy apart is its mechanical simplicity combined with sophisticated design. Unlike toys that require batteries or buttons, B Balls relies on physics—your movement powers the internal rotation. The anatomical shaping and premium silicone mean it's genuinely comfortable for extended wear. See the full BDSM Australia range of Luxury Sex Toys to explore other precision-engineered options.

How to use a luxury sex toy

Start by applying generous water-based lubricant to the tapered tip and your anal opening. Insert slowly and deliberately, allowing the anatomical design to guide the smaller sphere in first. Relax and let your body adjust. Once fully inserted, the base will rest comfortably, and any movement you make—walking, shifting position, gentle hip motion—will activate the internal rotating weights, creating dynamic stimulation.

Experiment with different activities to discover what feels best: sitting, standing, walking, or gentle rocking all produce different sensations as the weights respond to movement. Many people enjoy wearing them during intimate encounters with a partner for added sensation, or during everyday activities for discreet arousal. See the full BDSM Australia range of Sex Balls to compare other weighted options. Always clean thoroughly after use with toy cleaner or mild soap, rinse completely, and store in the provided pouch.

Care and storage

Clean the toy thoroughly after each use with a specialized toy cleaner or mild soap and warm water. Rinse completely until no residue remains, then air dry on a clean towel. Store in the provided soft pouch away from direct sunlight, heat, and sharp objects. Inspect the silicone regularly for any signs of wear or damage. Keep away from other silicone toys to prevent material 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 →

B Balls are exceptional for psychological control during scenes. The rotating weights create constant, unpredictable stimulation that my submissives cannot control or predict. Wearing them while performing tasks—cleaning, serving, maintaining protocol—forces them to manage sensation while obeying commands. Watching their composure crack as the internal rotation intensifies is deeply satisfying.

I use these to demonstrate absolute dominance over the body and mind. A submissive wearing B Balls during extended scenes experiences continuous stimulus they cannot pause or adjust. They must maintain focus on my instructions while their body rebels against the sensations. The psychological surrender is profound—they learn that control lies entirely with me.

Positioning matters strategically. Certain movements amplify the weights' effect, creating moments of intense stimulation I can trigger by commanding specific postures or activities. My submissives develop acute awareness of how their body's motion directly feeds their own torment. This feedback loop—movement equals sensation equals control—becomes the foundation of deeper submission and obedience in future scenes.
