The verdict
Get the Hismith 11.5" XL. It's 2.7 inches across, dual-density, and the KlicLok fitting clicks straight into a Hismith with nothing else to buy. Want thick without the commitment? The Fat-boy is 2.2 inches wide and about half the weight.
Our No. 1: Hismith 11.5" XL Dual-Density KlicLok Dildo
- Thick on a machine means 2 inches wide and up. Go one step below what you'd pick by hand.
- A native KlicLok fit wobbles less than a suction cup once the toy gets heavy.
- Past about two pounds, keep the toy on a steel frame.

No. 1 · Hismith
Best overall
Hismith 11.5" XL Dual-Density KlicLok Dildo
Hismith's own thick one: dual-density silicone, 8.5 insertable inches and 2.7 inches across at the widest, with the KlicLok fitting built in. It weighs 2.8 lb.
Pros
- Native KlicLok fit, nothing to buy extra
- Squish outside, backbone inside
- A tapered tip that eases the girth in
Cons
- 2.8 lb: a compact machine will struggle with it
- KlicLok only, so it won't fit a Lovense Mini
Why it ranks: The thickest toy here that clicks straight into a Hismith, so there's no plate and no play in the mount. That weight belongs on a steel frame.

No. 2 · Hismith
Best first thick toy
Hismith 9.25" Fat-boy KlicLok Dildo
A single-density silicone shaft with a defined head, 6.9 insertable inches and 2.2 inches at its widest. The KlicLok fitting is built in, and it weighs 1.39 lb.
Pros
- Fuller than most included toys without being extreme
- The easy one to keep going with
- Clicks straight into any Hismith
Cons
- One firmness all the way through, no soft outer layer
- KlicLok only: no use on a Lovense Mini or a dock
Why it ranks: The thick pick that won't wear you out: a bit over two inches wide and light enough for a long session, on a mount that needs no extra parts.

No. 3 · Hismith
Widest realistic
Hismith 9.5" Ultra-Wide Dual-Density Dildo
The widest realistic toy Hismith makes: 3.2 inches across, 6.5 insertable inches, dual-density silicone with balls, at 2.4 lb. The KlicLok connector unscrews, and a suction cup sits underneath.
Pros
- The girth pick, for riders who already know their size
- Take the fitting off and it stands on its own
- Give on the outside, support through the middle
Cons
- 3.2 inches wide is a lot, even for thick-toy fans
- 2.4 lb, so keep it on a steel frame
Why it ranks: For riders who already know they want serious girth. Unscrewing the connector leaves a suction cup, so the same toy moves from the machine to a dock.

No. 4 · Colours
Best non-realistic
Colours Pleasures Thick 8" Silicone Dildo
A bold purple shaft in body-safe silicone, 6.75 insertable inches and 2.1 inches at the widest point, on a strong suction cup.
Pros
- Holds on a plate, a dock or tile
- A manageable step up in girth
- Harness compatible
Cons
- Frame machines hold it by a suction plate
- One firmness throughout, not dual-density
Why it ranks: The non-realistic thick option. Two inches across is a real step up from the toy in the box, and the base sticks wherever you press it.

No. 5 · Pleasure Engine
Best realistic suction cup
Leman Russ XL 8" Dual-Density Dildo
A realistic dual-density shaft with balls, 8 insertable inches and 2.14 inches wide, on a 3-inch suction cup. Pleasure Engine flags it as a very large toy.
Pros
- The longest realistic shaft here, with some give
- A wide base gives the plate plenty to grip
- Realistic head, veins and balls
Cons
- Needs a suction plate on a frame machine
- Pleasure Engine's own note: measure before you order
Why it ranks: The longest realistic thick toy here that isn't a Hismith exclusive, and its broad base gives whatever holds it plenty of surface.

No. 6 · Fukena
Heaviest
The Chonker by Fukena
Strictly for big-toy lovers: 7.5 insertable inches, 9.3 inches around at its thickest and 2.66 lb of dual-density silicone on a 3.4-inch suction cup.
Pros
- Serious girth with a forgiving outer layer
- Wide cup for a solid seal
- Realistic shape and balls
Cons
- Too heavy for a Lovense Mini or a handheld dock
- On a Hismith it needs a suction plate; the extra-large one is $59
Why it ranks: The big-toy pick, and the reason some people buy a Hismith in the first place. That weight belongs on a full steel frame, never a compact machine.

Notes from Bedside CSO (Chief Sex Officer)
Notes from Bedside CSO (Chief Sex Officer)
A thick dildo you can ride by hand for ten minutes is a different toy once a machine takes over. The stroke never fades and it never pauses, so the girth that felt perfect in your hand can be too much by minute five.
Everything here is real silicone, at least 2 inches across, and checked against the connector it actually fits. KlicLok toys click into a Hismith. Suction-cup toys need a plate on a frame machine, or they go straight on a dock. For slimmer upgrades, Best dildos for sex machines starts smaller.
Before you buy
Buying guide
How thick is thick
Two inches across is where a toy starts to feel thick, and everything here clears that. The Fat-boy at 2.2 inches is the gentle end. The Hismith XL at 2.7 inches is the one most thick-toy fans settle on. The ultra-wide at 3.2 inches is for people who already own something close to that size. If you have to guess, buy the smaller one.
Connector first, girth second
A Hismith takes KlicLok toys with a click and no extra parts, which matters once a toy weighs two pounds: a suction cup can creep under that load. Suction-cup toys need Hismith's plate instead, and the biggest of those plates runs $59. Vac-U-Lock machines such as the Lovense Mini aren't a match for this list: these toys are heavy, and not one of them takes that plug.
Weight and the frame under it
The Fat-boy is 1.39 lb. The XL is 2.8 lb, and the Chonker is 2.66 lb. A compact machine wasn't built to swing that back and forth for half an hour. Keep anything past about two pounds on a full steel frame, and check the mount still sits tight after the first minute.
Lube, and starting shorter than you think
Thick silicone needs a lot of thick water-based lube, and it needs topping up. Set the stroke near its shortest before you switch on, and only lengthen it with the machine stopped. Depth plus girth gets intense fast.

FAQ
Common questions
- What counts as a thick dildo for a sex machine?
- About 2 inches across and up. On a machine, start one step below the width you enjoy by hand, because the stroke never lets up.
- Do thick dildos fit a Hismith?
- Yes. Hismith's own thick toys use KlicLok and click straight in. Suction-cup toys need one of Hismith's plates, and the biggest plate runs $59.
- Can I use a thick dildo on a Lovense Mini?
- Not these. They're heavy, and the Mini's mount is a different system entirely. It does better with a lighter toy made for it.
- Will a suction cup hold a heavy dildo?
- On a clean, dry plate, pressed on hard, yes for a while. Recheck the seal after the first minute. Past two pounds, a KlicLok fitting holds more reliably.
- How much lube does a thick toy need?
- More than a slimmer one, and more than you'd use by hand. Use a thick water-based lube on silicone and keep the bottle where you can reach it.
