Hey, whoa. How’s everyone bee- could you imagine if people really just consisted of both a mouth and an ambiguous lower region non-mouth hole that were perfectly connected like a fleshy highway tunnel to sex town? Unfortunately I just did while halfway through writing that. It sucked. Don’t read the opening sentence.

On the brighter side of things, this inhuman portal-to-hell-inducing form factor works great when it comes to onaholes. “All the fuck with none of the muck” as they never say in show business.

But yeah, as far as the whole mouth-on-one-end-and-vagina-on-the-other, last year’s ONDO! NUPU really tickled my dickle with some absolutely incredible attention to detail. Each side genuinely felt completely different and I still have it in fairly heavy rotation for my various erections as a result.

It even made me a believer in open-ended dick tubes after years of hate and/or squirting cum onto my laptop screen. A true religious experience, even with the tragic knowledge that sperm is potentially trapped down that impossible space within the bezel.

Anyway good yeah, disgusting. The ONDO! also happened to be a big seller for retailer MotsuToys especially, so now they’ve decided to try their own hand at the concept with another in-house KYO branded release.

Here’s the KYO Crystal Mouth.

Right off I’ll admit I’ve had this product for bloody ages now – months even! Jesus this review is so stupidly late. Without getting into some kind of word-based mental breakdown, I’ll just say this year has been a bit of a dump year hey. Sorry! But! I have been using this almost every day since then! So that’s probably a good sign.

I’ll tell my psychiatrist that next time I see him, I’m sure he’ll agree. Jammin’ my cock in the same human centipede-esque cum extractor on a daily basis.

Absolutely.

– Unboxing / Presentation – 

I dunno if this actually had anything to do with it, but Australian customs held onto this package for a good three weeks or so with no explanation (just a standard ‘we opened your package for inspection haha’ slip) and honestly I reckon it was probably because some cunt there took a peek and saw the combination of ‘Crystal Mouth’ and its ‘get addicted…’ slogan.

Geddit? Crystal Mouth… crystal meth… delicious… ham.

Great! Sorted.

The packaging here isn’t particularly fancy and doesn’t include any lube at all, but at least the onahole is pretty secure in that cardboard tube during shipping.

Again I’m really not sure what customs did here, but the overall package looked like it’d been sat on by at least four elephants, yet this survived perfectly intact.

Crystal Mouth is a bit of an odd one when it comes to the overall texture. The build feels really… gummy? Tighten your grip just a tad and you’ll be able to sink in pretty good, yet there’s still somehow a good dense feeling to it all. I like it.

I’m guessing the rubber rings play a big part in this, but more on that later because HERE’S A MOUTH.

Wow it’s not easy taking photos of a semi-transparent onahole. Then there’s the added challenge of noticing what’s either a stray pube or cat hair on its lip – a crisis for sure.

But yes! Crystal Mouth has a soft set of lips on it (prepare for the pink colouring to rub off basically as soon as you rub one out) along with some hard plastic front teeth, a chunky blob of a tongue which has some limited movement, and a fully ribbed roof thingy.

Honestly it does look better in person, especially over your dick. There’s a good pick up line to use btw, just frantically point at one of your various holes whilst saying it.

On the other side of Crystal Mouth we’ve got ourselves a classic vagina. The entry point is clearly MUCH smaller here and that’s… about it really. Not particularly detailed (especially compared to the ONDO! NUPU) but eh.

With some cheapshit RGB lighting, you too can have unlimited fun with a transparent onahole before, during and even after cumming.

– Feeling –

Just like ONDO! NUPU, I’ll break this down depending on which end you go with.

Ideally you could simply keep swapping between both holes as you wank for more variety, but then you risk a disastrous mixture of pre-cum and lube flying all over the place with each frantic Tony Hawk kickflip of the chaotic rubber vagina-mouth.

Goin’ in mouth first:

Pushing through Crystal Mouth’s… crystal mouth sure looks nice, with its soft goo-like lips latching on tightly as they morph around your shaft. That’s a good human thing to say. Unfortunately though the pink colouring all but vanished the very first time I washed it (most of it ended up on my dick), which is a bit sucky.

The teeth here are made of fairly hard plastic – not quite as brutal as The Mouth of Truth – but still on the rougher side of things. Personally I’m all for this as it offers a huge wave of stimulation scraping down your shaft every time you thrust forward, but you may wanna switch to the vag side pretty quick if chompers aren’t your thing. Still good in short bursts perhaps.

After defeating the teeth barrier, your head will quickly find itself either slamming into the tongue’s tip or sliding right past it. Gamblin’ with ya stamina. Either way the material is like jelly and has an almost scary way of cupping underneath your shaft with each stroke. It feels fucking fantastic, especially as it helps grind you up against some beefy ribbed textures above.

Then you get to Crystal Mouth’s halfway point which is the real star of the sperm show. Just like ONDO! NUPU, both entry points are separated in the middle by huge rubber rings which surround the tunnel to keep it nice and tight.

These are wild, man. Every time you reach the throat and begin to enter the vagina (backwards) your shaft is heavily punched by these rings. It’s an incredibly distinct feeling, like someone’s just crushing your dick in the nicest possible way. They strike and gently tug at your head non-stop.

To me the rings seem waaaay stronger than ONDO! but the tunnel texture isn’t as detailed and the overall material itself is much more forgiving, so this kinda balances everything out.

Goin’ in vagina first:

As expected, this is the vastly softer and more forgiving option than having plastic teeth whittle down your willy. Even I’ve found myself just sticking with this hole through most of my time with Crystal Mouth.

There’s no real defining checkpoints here, but holy shit is it tight. Just overall really… pleasant? Taking it slow and letting the rings fully massage my head with each stroke after popping through the vagina’s squishy, narrow passage sure is a thing.

On a completely unrelated note, I promise this’ll be the first and last review I refer to the penis as a willy.

Jet Set Willy’s the only one for me.

Going in through the vagina also has the advantage of mostly avoiding the jagged scraping sensation of the teeth once you poke through the other end. You’ll only really feel ’em when you yank back down, but it’s still dulled compared to actually face-fucking the tube blob.

– Cleaning –

Easiest shit in the world. You ever had one of those where it’d just magically vanish right down the toilet and then there’d be barely anything left to wipe? That’s an easy shit man. Hassle free. The good life.

Crystal Mouth is kind of like that, probably? You can just run one end under the tap and it all flushes out the bottom. If you’ve accidentally lost a peanut inside the onahole or whatever you can even see it with ease thanks to the entire thing being transparent.

So far the material’s gotten a biiit sticky after all these months of use, but nothing too serious. Rubbing some cornflour (UK/AU) or cornstarch (US) on there helps a lot. I’d highly recommend keeping a box of that around for onaholes in general.

Also cooking?

– Summary –

Crystal Mouth is another open-ended onahole with two totally different sides done right. The mouth provides that rougher edge, while the vagina offers just an overwhelming sense of squishy pressure. No matter how you go at it, the mid-section between ’em is absolute bliss. Not quite up to the level of ONDO! NUPU for me personally, but it’s damn close.

With a high level of durability and hassle-free cleaning process, Crystal Mouth’s a solid option if you’re after some variety in your see-through dick tube.

Crystal Mouth

+ Both sides have some great detail and feel totally different
+ Rings in the middle have some serious tugging strength to them
+ Squishy gel-like material works really well at keeping things tight but not overwhelming

– The teeth may be too hard if you’ve got a sensitive head
– That pink colouring on the lips will rub off almost instantly and be lost to the sands of time forever just like Prince of Persia, RIP
