The Fun Factory B Balls Duo brings a kinetic twist to anal play. Unlike static plugs, this design houses weighted inner balls that shift and roll as you move — sitting, walking, or changing position triggers a rippling sensation that turns everyday motion into stimulation. It's a plug that responds to you, making it particularly engaging during partner sex or activities that involve body movement.
The tapered tip eases insertion, while the contoured base sits flush between the cheeks for discreet, comfortable extended wear. Made from body-safe silicone, the plug is non-porous and pairs well with water-based lubricant. The reactive weight play makes this a strong choice for those who want more than passive fullness — it's designed for wearers who enjoy sensation that builds with activity rather than staying constant.
This isn't an everyday starter plug. The internal weight mechanics deliver a different kind of feedback than rigid or static designs, which some users find more engaging and others find distracting. If you're accustomed to traditional plugs and want something that interacts with your movement — or if you're incorporating anal play into partnered sex where the shifting sensation adds a layer of arousal — the B Balls Duo delivers a distinct experience. It's a thoughtful option for the drawer that already has the basics covered.

How to Use
Apply water-based lubricant generously to both the tapered tip and the anus. Insert slowly, pausing to allow the body to relax around each curve. Once seated, the base should rest flush against the body. The internal balls will shift with movement — try standing, sitting, or engaging in partner play to explore the sensation. To remove, relax the muscles, apply more lubricant if needed, and pull gently on the base. Clean thoroughly with warm water and toy cleaner after each use.
Compatibility
- Lubricant: Use water-based only — silicone lube can degrade the silicone material
- Cleaning: Wash with warm water and toy cleaner or mild soap; avoid boiling due to the internal weight mechanism
- Storage: Keep away from other silicone toys to prevent surface bonding
Frequently Asked Questions
What makes the B Balls Duo different from a standard butt plug? The B Balls Duo contains weighted inner balls that shift and roll when you move, creating a reactive sensation rather than the static fullness of traditional plugs. This makes it particularly engaging during activities that involve body movement.
Is the Fun Factory B Balls Duo suitable for beginners? While the tapered tip aids insertion, the reactive weight mechanism delivers a distinct sensation that's better suited to users already comfortable with anal play. Beginners may find a simpler static design easier to adjust to initially.
What lubricant should I use with the B Balls Duo? Use water-based lubricant only. Silicone-based lubricants can degrade the body-safe silicone material of the plug over time.
Can I wear the B Balls Duo for extended periods? Yes — the contoured base is designed to sit comfortably between the cheeks during extended wear. Start with shorter sessions and listen to your body, especially as the internal weights create ongoing sensation with movement.
Does the Fun Factory B Balls Duo ship discreetly to Canada? Yes — every order ships in plain, unmarked packaging with confidential billing.
