Fun Factory B Ball Uno | Rumbling Weighted Anal Plug

Embrace motion-driven pleasure with the Fun Factory B Ball Uno, a cleverly designed anal plug that responds to your every movement. Inside its sleek body rests a weighted ball that bounces, rolls, and rumbles, turning walking, shifting, or subtle motion into waves of stimulation.

Its tapered shape ensures smooth insertion, while the narrow base offers comfortable wear for extended sessions without drawing attention.

How to Use

1. Begin with a relaxed state: take deep breaths and allow your body to prepare for insertion.

2. Use a generous amount of water-based lubricant on both the plug and the entry area for extra slip.

3. Insert the B Ball Uno slowly, using the tapered head to ease yourself in.

4. Once inserted, allow your natural motion—walking, shifting, even subtle movement—to activate the internal weight’s rumble.

5. Focus on sensations and adjust your movement or posture to explore how different angles feel.

6. To remove, hold the base firmly and pull gently, breathing and relaxing as you go.
