Once again, the MotsuToys shop offered us the chance to give our opinion on a rather unusual sex toy. At least, unusual for us. This type of sex toy is by no means rare and is actually quite popular, but I’d never tried one before: a “bust”-type masturbator, the Tsundere Girl Mecha Shiko Big tits 2600. These masturbators, which are sort of hybrids between Fleshlights, Tenga eggs and RealDolls, had been making me curious for a while.
That said, we’re dealing with something probably a little more modest than the previous sex toy they sent us, the Narumi’s Thicc Ass.
What exactly does “Tsundere Girl” mean?
To give you the quick version (but if you’d like more detail, the Wikipedia article on the subject will probably explain the concept much more precisely), a Tsundere is a female anime or manga character who is initially presented as angry, grumpy and stuck-up, but who turns out to be really cool, kind and endearing as the story unfolds. This type of character is very common in Japanese comics and cartoons.
A few more concrete examples, some of which you’ll probably know:
- Asuka Langley Soryu in “Evangelion”
- Charlotte Pudding in “One Piece”
- Yui Kotegawa in “To Love-Ru”
- Kurisu Makise in “Steins;Gate”
- Taiga Aisaka, the “Palm-top Tiger”, in “Toradora”
- Mikoto Misaka in “A Certain Scientific Railgun”
Sex toy packaging
As with many MotsuToys products, the packaging is fairly important here. Functionally, it’s a sturdy enough cardboard box with a base that holds the masturbator (which is itself wrapped) in a fixed position. In other words, nothing special here; it does the job.
However, the box design gives the sex toy a certain value, a bit of “lore”, which makes the object much more fun. There’s an anime/manga-style illustration of the character whose bust this is, all sorts of information and measurements, and little drawings.
As these are Japanese products, everything is written in Japanese, but even without being able to read it, as is the case for me, it adds to the charm.
In short, you want to keep the box, just as you often want to keep the box for an anime figurine.
What the Tsundere Girl masturbator looks like
Let’s not beat about the bush: it’s a bust.
You can probably see the photos, but if not, it’s pretty easy to describe. Imagine a RealDoll, a realistic doll; shrink it, then remove the limbs and the head.
Apart from its reduced size, the proportions are somewhere between realistic and cartoonish (which isn’t a criticism), for aesthetic reasons, but also, I suppose, to make the toy’s size possible. The chest is substantial, and scaled up to 1:1, we’d clearly be looking at a very large bust. In my opinion, both openings look quite convincing, especially the vulva, whose lips are quite well done and subtly pinker.
I know a lot of people will wonder about the creepy side one might think is inherent to this type of sex toy, and in my opinion, it’s not too bad here. There are no unsettling stumps; everything is rounded, and, forgive me if I don’t have the writing skills of a great author when it comes to descriptions, but to me it looks more like a potato-shaped body than anything disturbing.
For the technical details, here are a few measurements and specifications for the thing:
- Weight: 2670 g
- Vaginal tunnel: 155 mm
- Anal tunnel: 138 mm
- Length: 38 cm
- Width: 16 cm
- Hip circumference: 46cm
- Waist circumference: 30,5 cm
- Bust circumference: 48 cm
- Weight: 2670 g
- Brand: XTC Japan
Texture and materials
Like most sex toys of this type, such as the Ondo! Nupu and the Narumi’s Thicc Ass, as well as pretty much all Fleshlights, this sex toy is made of TPE, an elastomer. So, nothing out of the ordinary. It’s reassuring to know, though, that it contains no phthalates and is safe for the body. Still, it’s worth remembering that these materials are porous (so best not to lend it to anyone).
In practice, if you’ve ever handled a Fleshlight-type masturbator, it’s similar: stretchy and soft. What feels different from Fleshlights, though, is that this one has a lot more volume and mass, which changes the sensation for the better.

The breasts are “squishy” and very pleasant; the bum is soft and yielding.
To give you an idea of how firm it is, the sex toy will stand up leaning against a wall, but if you pick it up vertically, holding it by the bum, for example, the upper body droops a little and folds over, as if our Tsundere were bending down.
Using the Tsundere Girl masturbator
The masturbator has two penetrable parts: an anus and a vagina. On top of that, it has lovely soft breasts, a lovely soft bum, and hips that make it easy to hold.
Whichever opening you choose, it works very well with the belly facing down or facing up (you could call those doggy style or missionary, if you prefer).
It’s quite easy to use by laying it flat on a surface such as a desk, chair or bed, and it’s also very easy to use vertically, holding it like a traditional masturbator.

The sensations
I was very pleasantly surprised by the sensations. I think it’s hard to do better with this kind of product (sure, it’s probably better with a 10,000-euro RealDoll, but let’s compare like with like).
I found the internal structures and textures realistic enough to give convincing sensations. The two openings feel quite different, and the sense of realism is there. As for the outside, the size obviously limits how “convincing” the sensations can be, but with a bum and hips, it’s still more realistic in feel than another type of sex toy. In the heat of the moment, the breasts are probably the most realistic part, but never mind; they’re still soft and pleasant.
Ultimately, it really is halfway between Fleshlight-style masturbation and something closer to actual sex. I think that’s the main appeal of this sex toy.

Cleaning
Cleaning it with soap is a little more of a faff than with a Fleshlight, where you can remove the sleeve, but it’s still easy. The sex toy isn’t too bulky, so you can clean it fairly quickly at the sink, and it’s quite easy to feel confident that you’ve cleaned it properly.
Drying it is a bit more of a pain, though, as there’s no air circulation. It’s a real drawback, but bear in mind that this is a common drawback shared by all these types of sex toy.
And on that subject, MotsuToys also sent us a little cleaning and heating tool specifically designed for the job: sterilising all these types of sex toy. It can also preheat them to reach a realistic body temperature.
We’ll publish a short, separate review of it very soon, since it’s sold separately and can be used with any masturbator, but I wanted to mention it here because it might just be the solution.

Conclusion on the Tsundere Girl masturbator
Personally, I thought the Tsundere Girl masturbator was particularly cool, pleasant to use and practical. In particular, it’s much more practical, easier to use and easier to clean than bulkier realistic masturbators such as the Narumi’s Thicc Ass, or indeed any sex doll. Physically and psychologically, it’s a bit like wanking, wanking with a Fleshlight, and using a sex doll, or at least somewhere between all those things. The “Lore” is amusing and adds a lot to the pleasure of owning and using the thing. And as an added bonus, it’s also much cheaper. Not exactly cheap, but still affordable, at around 120 euros. In short, in terms of value for money: nothing exceptional, nothing noteworthy. Just a normal, fair price.
The only drawback is if you find it creepy. I did, but you get used to it very quickly and immediately see it for what it is: a masturbator, full stop.
MotsuToys also offers many other masturbators associated with various types of anime character, such as the Yandere, and so on.
Some cost around 30 euros, others 400 euros; this one seems to me to be a perfect middle ground.
Thanks to Motsutoys for providing us with the masturbateur Tsundere Girl for this review
