Bakunyu Assistant Alchemist: Onahole Review

Today we'll be taking a look at the Bakunyu Assistant Alchemist onahole created by Love Factor. The cute alchemist on the cover really reminds me of something, but let's forget about that for now and see how the toy holds up against her alchemy!

The Box

It's another anime themed onahole with a very cute anime alchemist girl on the cover. Her clothing and appearance really reminds me of a certain protagonist from an alchemy-based game series with super thick thighs - but it must just be a coincidence, right?  Anyways, here's some pictures:

The box art really emphasizes the onahole's big breasts - which makes sense given that the title literally includes the word "bakunyu". Outside of that, there's pictures showing the inside tunnel and the alchemist-esque outfit stitched onto the onahole. I'm not entirely sure what makes this outfit alchemist-themed specifically as it looks like a regular dress, but I'm probably just not in the know about anime alchemist girls.

The box is unfortunately missing some details about the toy's dimensions - though I could luckily find some of the information on the official website. There's no info about the official tunnel length, so I had to guess based on the pictures. Anyways, let's move onto unboxing!

The Contents

The first thing I noticed is the box is fairly rigid and thicker than your average box - which really helps make sure the onahole is protected during transport. The onahole also comes in a nice large molded plastic shell with a cover on top, which is great for protecting the onahole from getting deformed and preventing oil from leaking into the box. 

Overall, very good box quality - I always really appreciate it when onaholes come in plastic shells for protection. Let's see how the onahole itself fares!

Onahole: Appearance

Here's some pictures of the onahole - please excuse some of the dust on it, this one had been lying around in a toy bag for a bit too long.

It's a relatively large, cute onahole with big (bakunyu) breasts, slim waist, and a decently defined butt. The dress stitched onto the onahole also looks alright, but I've never been a big fan of clothes stitched onto onaholes, especially since it's the same skin color as the rest of the toy. Makes me think the dress is part of the alchemy girl's skin - as if something in the alchemy concoction went wrong!

The opening to the vagina itself is standard, with some obviously fake skin-colored vagina lips and a tiny clit that makes the vagina look nice when viewed from top-down. The panties stitched onto the toy by the vagina also look kind of odd, but that's just my personal opinion.

The skin is on the firmer side - making the bakunyu breasts not super jiggly or fun to squish - they just feel like rubber clumps. The well defined nipples are nice to pull on, but there's generally a lack of texture around the nipples. For a toy that emphasizes bakunyu so much, the breasts are definitely underwhelming. Though to be fair, for an onahole of this size, there's not much that can really be improved, as there's not much material space to work with.

Speaking of size, this toy is fairly large and heavy as far as one-handed toys go. It's easiest to grip it by the waist, but the slimness of the waist and weight of the rest of the toy means it flops around quite a bit when doing so.

Onahole: Insides

Here's a picture of the inside cross-section provided on the box, and a low-quality video of the insides:

I couldn't find the official tunnel length listed anywhere, but based on the image I'd guess it's around 120mm - which is a pretty standard tunnel length. The opening looks fairly loose based on how flexible the vagina lips looked. After that, there's a bunch of ridges and nubs as you go to the end.

Right before the end, there's a small O shaped entrance that seems to be the cervix - but past that there's another even smaller O shaped entrance into a small, squishy cone. The first O shaped entrance is probably meant to be easy to penetrate, so it provides suction and the typical cervix penetration feeling. The smaller one is more difficult to penetrate, so it probably represents the real cervix and is meant to provide stimulation to the head as it hits around the squishy cone. 

It's an interesting design that might provide the best of both worlds - as often times cervix penetration toys offer no additional stimulation to the head past the suction. Anyways, let's see how it fares in practice!

Onahole: Usage

Let's see how this toy fares in action - in terms of textures, grip, and maintenance.

Textures

At the front, the bumps and ridges are especially noticeable when moving slowly, providing lots of stimulation. I'd recommend sometimes not going in all the way and just having the head go in and out of the first half, which provides a ton of stimulation. The toy is overall a bit looser compared to most toys, but not soft since all the textures are very noticeable.

Deeper in, the first "fake cervix" provides decent cervix penetration feeling along with suction if you squeeze air out beforehand. Note that the big breasts on the toy actually make squeezing air out of the end chamber fairly difficult though. 

After the first cervix you hit the real cervix. It's basically impossible to enter because the hole is tiny and the cone itself is firm yet malleable, so you mainly just hit the cone with your member. The firmness and squishiness of the cone actually provides quite a bit of extra stimulation and gives a nice "cervix hitting" sensation. Paired along with the suction from the first cervix, the back of the toy provides a lot of stimulation beyond just suction.

Overall, the textures are great and highly simulating throughout the entire toy - really giving it a lot of variety so that you'll never get bored.

Grip

The substantial weight to the toy makes it satisfying to grip tightly as you use it, and provides good realistic pressure onto the member. However, its tiny waist means it'll flop around quite a bit since the slim waist doesn't provide nearly enough support for the heavy weight on the two ends (I blame the large breasts). 

The size and weight means that it's easy to use in other positions where you use your hips to move instead - like lying the onahole flat on a table, or maybe prone-boning it while lying down, though it's probably still a bit too small for the latter.

Maintenance

Although I guessed that the tunnel length is 120mm, it feels a lot longer than that when trying to clean it! It feels more difficult to get to the end as opposed to other toys of similar length, likely because of its weight and tunnel structure. The tiny cervix cone at the back is also very hard to dry, since it'll be hard to get a piece of cloth inside to fully dry it out. Luckily, the toy isn't super tight so as long as you get it 90% dry the rest will probably air out.

The toy also seems quite durable. I've used and clean mine multiple times and it doesn't actually show much sign of wear or tear. The skin also hasn't needed re-powdering since purchase - it definitely has become stickier, but not to the point where its noticeable during usage unlike many Magic Eyes toys.

Summary

She looks awfully familiar...

The Bakunyu Assistant Alchemist onahole is a toy that does everything well. It's got a slim yet busty body, and a variety of stimulation throughout the toy - front and back, cervix penetration and suction sensations included. Whatever alchemy they did to produce this toy worked pretty well!

For $60, the toy is a bit expensive, but more than justifiable given its large size, hefty weight, variety of stimulations, and durability. Unless you really hate toys that take some effort to clean, large breasts, or a certain game series involving cute anime alchemists, this is a great toy to try.
