Ju-C 4U

G-Project. This onahole brand still remains in my top5, with good quality products featuring cute packaging. It’s been some time I didn’t review any of their products, so I picked one of their “Ju-C” series: Ju-C 4U.



For the product illustration, G-Project chose a cute busty schoolgirl lifting up her skirt, made by artist ไฝƒ็…ฎใฎใ‚ŠใŠ.


Inside the printed plastic box, you’ll find the onahole, a sample of water-based lube, and G-Project storage bag. That is pretty good !

The lube is made by PePe, so unsurprisingly it’s very good quality and you get enough for about 2 uses. While the storage bag is in plastic instead of something better like cloth, it’s still good to have to store the onahole.


The Ju-C 4U is an average sized onahole made of TPE, it’s pretty flexible and has as good as no smell. It doesn’t get oily, and it’s surface is rather smooth and just slightly sticky.

It’s entrance is a single round hole shaped to allow easy insertion.

Inside, Ju-C 4U features hybrid structures: it’s first half is single-layer and see-through with several “portals” leading to a round chamber with bumps, it’s second half becomes dual-layer probably imitating the uterus, rather firm wavy structures + little spikes and finally a round bottom chamber for suction effect.


A couple drops of lube inside, and here we go !

The first half provides a nice snug feeling and does wonders on stimulating the glans, you’re totally feeling penetrating each “portal” and then having your tip gently scraped by the bumps.

Then, you push a bit more and you find yourself in the depths of the abyss, your glans entrapped by the spikes !

The bottom definitively shows more resistance, I found myself being almost forceful to bring myself in. The transition -feeling sliding through the “cervix”- sure is nice, but over time it’s annoying as you’re unsure if you penetrated it fully and are hitting at the bottom, or if you have not yet.

So I worried about how the bottom layer would endure this treatment over times. And indeed, eventually…

… the bottom layer, ripped, detached and came out, leaving the second half of the onahole as a -completely- smooth big vacuum chamber: still usable, allowing now to see your dick fully penetrating it, but yeah. If anything, now we get a closer look at the bottom layer’s structures.


Before the bottom layer detaches, treat it like any dual layer onahole: just spread its entrance open and clear the interior with water and soap using your fingers.

If/when the bottom layer detaches, you can treat the onahole like any other single-layer onahole: turn it inside out so you can thoroughly clean it with water and soap, pat it dry with a cloth, leave drying for a few hours in the open air (away from direct sunlight) or inside it’s storage bag.

To make the outside surface extra smooth, you can apply talc or corn starch.


Nice try, G-Project. However, your dual layer designs need some perfecting, as in my example the layer start separating after only a handful uses of Ju-C 4U.

That’s too bad since the onahole structures feel pretty good and I could still use my bottom-less onahole sometimes. However, you don’t get your money worth with Ju-C 4U  :/
