Fun Factory B BALLS DUO Silicone Anal Plug

Fun Factory B BALLS DUO Silicone Anal Plug is a two-sphere weighted butt plug that combines sculptural design with satisfying internal stimulation. The dual spheres sit inside your ass, moving with your body to create sensations that feel far more organic than traditional vibrations. Built with medical-grade silicone and a stabilizing flat base, this anal toy gives you hours of discreet wear or intense solo sessions whenever you want them.

What It Does

The two silicone balls shift and roll inside your rectum as you move, creating a gentle rolling sensation that builds arousal without needing batteries or buttons. Unlike rigid plugs that sit still, these spheres respond to your body's natural motion—walking, clenching, or grinding—making your ass feel continuously touched and awakened. The tapered tip slides past your sphincter with minimal resistance, while the bulbous design fills you completely once seated. Medical-grade silicone holds its shape perfectly while remaining soft enough that your anal muscles can grip and release without discomfort, creating a feedback loop between your body and the toy itself.

Arousal builds differently with weighted balls because the stimulation feels alive rather than static. Your prostate gets nudged and massaged as the spheres shift, triggering deeper pleasure that creeps up through your pelvis. Orgasms achieved with this anal fullness tend to arrive with a different quality—your whole lower body contracts around the plug, amplifying the release and creating cumming sensations that radiate outward from your ass instead of focusing solely on your cock.

Technical Specs

• Total length: 13 cm with 4 cm maximum diameter
• Medical-grade body-safe silicone, waterproof IPX7 rating
• No power source required—completely manual, always ready
• Tapered insertion tip measures 2.5 cm at narrowest point
• Flat T-bar base prevents full insertion and enables easy retrieval
• Cleans easily with warm water and unscented soap

How To Use It

Warm your ass with a few minutes of external play, then apply water-based lubricant generously to both the plug's tip and your asshole. Position yourself on your back, knees drawn up, or bent forward on all fours—whatever gives you relaxed access to your rear. Press the tapered point against your sphincter and breathe out slowly as it slides in. The balls will settle inside naturally once fully inserted, and the flat base sits flush against your cheeks. You can wear it during everyday activities or lie still and feel every millimeter of fullness.

To intensify the session, start moving—rock your hips, clench your ass muscles rhythmically, or shift positions to feel the spheres roll in new directions. Combine the anal stimulation with hand work on your cock or prostate massage through the perineum. Many users find that deliberately tightening and releasing their sphincter creates waves of pleasure that build toward orgasm. When you're close, sustained clenching while the plug is seated inside often tips you over into cumming that feels deeper and more whole-body than standard masturbation.

Who It Suits

The B BALLS DUO works perfectly for anal newcomers because it has no motor to intimidate you and no buttons to figure out—just insertion and sensation. Experienced ass players love it for long-wear sessions throughout the day or for partnered play where their partner controls movement. Anyone exploring prostate pleasure will find the consistent internal pressure rewarding. The size accommodates most bodies without extreme stretching, though those with severe anal strictures should consult their doctor first. Skip this toy if you need external vibration or if you're looking for a larger plug meant for advanced stretching.

The B BALLS DUO occupies the sweet spot for intermediate anal exploration—more engaging than basic plugs, far less demanding than large insertables. Its non-vibrating design makes it ideal for quiet wear or situations where you want pure physical sensation without electrical hum. Choose this when you want to genuinely feel your ass during play rather than relying on motorized numbing.

Prostate Play Toys

While not exclusively a prostate toy, the B BALLS DUO's internal positioning creates consistent gentle pressure against your prostate during movement and clenching. Men seeking prostate sensation without vibration appreciate how the weighted balls encourage you to engage your pelvic floor muscles, which amplifies prostate awareness. It's less direct than a dedicated P-spot vibrator but more versatile for overall anal pleasure.

Expert Review from Our In-House Tester

I tested the Fun Factory B BALLS DUO during a weekend where I could wear it intermittently for hours. The 13 cm length felt substantial without being intimidating, and the tapered tip made insertion straightforward even when my ass was cool and tight at first. The medical-grade silicone surface is impossibly smooth—I barely needed lube beyond an initial application. Walking around my apartment, I could feel the balls rolling slightly with each step, creating this low-level arousal that never stopped but never became uncomfortable. By evening, I was horny enough to sit down and deliberately work the toy with clenching and movement until I came hard—the kind of climax where your whole core locks up and releases in waves. The flat base stayed exactly where it belonged throughout. A week later, I'm still reaching for it multiple times. The value is exceptional when you consider the 25-year warranty backing this toy.
