MonSuu

Both the toy and box art are cute, but all I can say is you could probably only use this as a head massager. Even doing that it'll take quite a bit of twisting and turning for it to finish you.
I'd say the material is little tougher at least compared to a Tenga Egg/pocket, Because of this its a little worrying to pump at all while using it since harder material toys tend to break when used a bit more recklessly.

I wouldn't really call this a blowjob onahole, but rather a onahole that resembles fan no hitori's hentai works where the woman is turned into an onahole.
The entrance is super small where even your pinky finger would need a bit of work to get into. So it does take some time to get your member in. You'll need to bend the head back to help line things up a bit. The material itself is pretty stretchy and fits really snug once you manage to get in. The tunnel itself is pretty simple, which is why I believe most of your enjoyment from this toy will be from the fantasy of it. Seeing how large you are down the throat or squeezing the boobs of the toy are what add to the experience. If you only care about how the tunnel itself feels then you are better off with other toys. Due to the snug sensations of the toy though, you can enjoy it for longer at your own pace. Considering the work it takes to get into it at the start, I think this is a good thing it doesn't cause you to nut immediately.
There are a few things to say about the outside of the onahole now. First the color is more of a pinkish than skin tone as shown in the product images. Second my onahole did stand up properly on flat services most times but would lean a bit to the side. Thirdly I was surprised but the actual onahole has more details on it than displayed in its preview picks, the onahole has those triangle pasties on her boobs similar to her 2D character.

Soft and squishy on the outside, but the tunnel is just firm enough to feel the details of the tunnel. Although the tunnel is a bit more mild. The weight of the toy is nice so it slides back down onto you since otherwise its a bit hard to grip. The back part of the tunnel is thin so for larger people id be very afraid of punch through the toy.

Maybe it's because I don't have much experience with harder onaholes. My only other one being the Yandere by Toysheart. But I can only say I was expecting more from the sensations. It just felt mild overall. It's good points also work against it in someway.
The cone part is great for grip and makes the toy really durable. At the same time I feel it makes it harder to squeeze air out of the toy to give it good suction. The cone shell makes it impossible to reach the end of the tunnel if you have a smaller member. Also if your member were too long you'd end up smashing it against a immoveable surface at the end.
Honestly it'd be nice if the picture advertising the product was translated so I could understand their explanation of the tunnel more. Maybe I'd understand its charm points more then.

You won't get the super entrance squeeze here like the Student Council President onahole, but Anal Kaikin Gal Bitch provides a nice snug experience. The overall size of the toy is small and the material somewhat soft. The entrance is still small enough to have that anal feel to it. Sensations along the tunnel would say are average but that means you can use it for longer sessions easier.
I would like to point out though that the images displaying the product are false advertisement. The Anal Kaikin Gal Bitch is pink in color. Also although the material is nice, I did notice a lot of tiny pin sized pockets or air bubbles along the surface of the toy, So quality can be questionable as I don't know if the inside tunnel suffered the same thing.
