Silicone Hand Fisting Dildo: 16.5"

What Is It?

The mother of them all.

The b-Vibe 16.5" Silicone Hand Fisting Dildo is an enormous, lifelike hand and forearm designed for experienced players who want to explore serious fullness, depth and fisting-style penetration.

Made from seamless, body-safe silicone, it begins with tapered fingers held together in an insertion-friendly shape before gradually widening through the hand and into the forearm. And unlike the smaller vibrating version, this one isn't about motors, patterns or gadgets. It's about size. Glorious, unapologetic size.

At approximately 41.9cm (16.5") overall with 39.5cm (15.5") insertable and a maximum circumference of around 23cm (9"), this is one of the most substantial toys in our collection.

A huge suction base keeps it securely anchored for anal or vaginal play and gives you the option of hands-free exploration on a suitable smooth surface.

Why We Love It

Sometimes there's simply no point pretending to be subtle.

This is an extraordinary toy for people who already know that they love big toys, deep penetration and serious fullness. The hand-to-forearm shape provides a progression that conventional oversized dildos simply can't replicate.

The tapered fingers are particularly clever. Rather than confronting the body immediately with the widest part of the hand, they create a narrower starting point before gradually transitioning through the knuckles, hand, wrist and forearm. That gives experienced users much more opportunity to slow down and let the body adjust as the size increases.

Then there's the length. Almost 40cm insertable gives depth lovers an enormous amount to explore—but there is absolutely no expectation that you take all of it. Two centimetres, twenty centimetres or the whole damn arm: your body gets the final say.

The suction cup makes a toy of this scale much easier to manage, too. Secure it to a suitable smooth surface and you can use your own body to control the angle, movement and depth rather than trying to manoeuvre an enormous silicone arm with your hands.

Is it ridiculous? A little.

Is it magnificent? Absolutely.

Passionfruit Says

"This is quite simply one of the biggest toys in the shop. Nearly 40cm insertable, with a full hand, wrist and forearm to explore, it's designed for people who already have plenty of experience with substantial penetration. We love the gradual shape, the beautiful silicone and the enormous suction base - but most of all, we love that it knows exactly what it is. Completely excessive. Completely fabulous."

Frequently Asked Questions

Exactly how big is it?

Very.

The toy measures approximately 41.9cm (16.5") overall, with around 39.5cm (15.5") insertable length and a maximum circumference of approximately 23cm (9").

This is an advanced toy intended for people who are already very comfortable with large penetration.

How does it compare with the 10.5" Vibrating Fisting Dildo?

The 10.5" version is considerably smaller and adds vibration.

This one sacrifices the electronics in favour of much greater length and girth. It's approximately 15.5" insertable compared with 9.75" on the vibrating model, with a maximum circumference of around 9" rather than 7.5".

If vibration is your priority, choose the smaller one. If your response to that toy is "but I'd like considerably more arm"—here you go.

Do I have to insert the entire hand or arm?

Absolutely not.

The length gives experienced players options, not a target. Explore gradually and stop wherever your body feels comfortably full. There are no prizes for reaching the suction cup.

Is it actually suitable for fisting preparation?

It can be useful for experienced players exploring hand and wrist-sized penetration, although a silicone hand isn't identical to actual fisting. A human hand can change its shape, respond to feedback and communicate; a dildo can't.

If you're still working towards this level of girth, we'd start with the Anal Stretcher Training Cone or Anal Fisting Trainer before moving onto the full hand.

Can I use it vaginally as well as anally?

Yes. It's designed for both vaginal and anal fisting-style penetration.

Is this suitable for beginners?

Definitely not.

If you're new to anal play, begin with small plugs and gradually progress through larger sizes over time. Even experienced players should warm up thoroughly before using a toy this substantial.

What's the best way to use it?

Slowly...and with a heroic quantity of lubricant.

Warm up thoroughly with fingers or smaller toys first. Add plenty of lubricant to both your body and the toy and introduce the tapered fingertips gradually, pausing whenever your body needs time to adjust.

Gently pushing out as you begin insertion can help relax the external sphincter. Never force the toy or treat discomfort as something you need to overcome.

Should fisting or extreme stretching hurt?

No. Intense pressure and stretching sensations can be part of advanced play, but sharp pain, burning or significant discomfort are signals to stop.

We don't recommend numbing or desensitising products for this kind of play, you need to be able to feel what your body is telling you.

What lubricant should I use?

Lots of a thick, high-quality water-based lubricant. The rectum doesn't self-lubricate, so don't be shy about stopping and reapplying.

Does the suction cup really hold something this enormous?

The broad suction base is designed to secure the toy to suitable smooth surfaces, allowing you to control the depth and movement with your body. It also includes a quick-release tab to help break the suction when you're finished.

Is it waterproof?

Yes. The non-powered silicone construction is waterproof and suitable for shower play.

How do I clean it?

There's quite a lot of it to clean!

Wash thoroughly before and after use with warm water and a quality toy cleaner or mild soap, paying particular attention between the fingers and around the detailed areas of the hand. Rinse thoroughly and allow it to dry completely before storing.
