About the Product

Fun Factory B Balls Duo is a weighted butt plug that responds to your movement instead of a motor. Two graduated balls are inserted one after the other, like anal beads, and the small weights inside them rotate as you move, creating sensations that range from gentle to powerful. It is completely silent, has a narrow base for discreet wear, and is designed for intermediate and experienced anal players who enjoy a feeling of fullness.

Key Features

  • Motion-reactive weights: Rotating inner weights follow your body, so the more you move, the stronger the sensation.
  • Two graduated balls: A 3.2 cm and a 3.6 cm ball give a progressive, filling experience.
  • No power needed: No batteries or charging, and no noise at all.
  • Narrow base: A slim, secure base can be worn under clothing and leaves other areas free during sex.
  • Flexible connector: A flexible but stable silicone link joins the balls for easier insertion.
  • Manufacturer materials: Fun Factory states it is made from medical-grade silicone and ASB plastic.

How to Use and Care

Apply plenty of water-based lubricant, which Fun Factory recommends, and insert the smaller ball first, relaxing before adding the second. Wear it during sex, solo play or while moving about to feel the weights at work.

Clean with a toy cleaner or warm water and mild soap after every use, then dry and store it away from other toys.

Your B Balls Duo is sent in discreet packaging with no branding, and we deliver to customers in the UK, in Ireland and around the EU.

Frequently Asked Questions

Is the B Balls Duo suitable for beginners?

Fun Factory designed it for intermediate and experienced users because of its size. If you are just starting out, a smaller single-ball plug may be more comfortable.

Which lubricant should I use?

The manufacturer recommends a water-based lubricant. Use it generously for comfortable anal insertion.

Can I wear it discreetly?

Yes, it is silent and the narrow base is designed to be worn under clothing without being noticed.

Does it vibrate?

No. The sensations come from rotating inner weights set in motion by your movement, so there is no motor or charging.

Order the B Balls Duo in white and dark violet and let your own movement do the work.
