Sujiman Kupa Big Rina ~ Cr4zyDuck

The original Open My Pussy! series: Rina used to my very first Japanese onahole back in January 2016. It’s litteraly the product who made me jump head first in that universe and got me addicted to those amazing TPE sleeves and other fantasies.

I was highly disapointed though when I had to throw it away due to the inner layer being in a mess and the back of the toy tore apart since the inner lenght was way too short for my size.

And now it’s finaly time to give a try to the newer and bigger version of that incredible toy with this resized size, the Sujiman Kupa BIG Rina !

Man this sure brings back memories, getting to fuck the newest version of your very first onahole…


The packaging looks really fine, overall it remains the same as the previous version but this time it has a goldish color in the large R letter (that stands for Rina I suppose) in the background. All the pictures are in very high quality and depicts the onahole on all different angles, showing a lot the amazing pinkish insides as well as a size comparaison between the two Rina.

I really like this feature since it really helps to see how much bigger this new one truly is.

An other thing that is truly unique to Rina’s packaging is that sort of post card inside the box which actually serves as Rina’s panties ! The same trick was already used for the original one, and the only other onahole box I’ve ever seen using the same kind of trick is Disgraceful Oppai Body.


And here is how the insides look like; with all the stuff safely placed inside a cardboard stand. It does not comes in a hard plastic case, but overall the onahole was in an incredibly good condition. Now that I’ve experienced the mess that was La Vie en ROSES SOFT with all the horrible marks on the product, I really don’t trust plastic cases anymore since even with those a disaster can happen…

Anyway, the onahole comes in one of those super soft and stretchy bag. I don’t think it’s plastic, actually I have no idea what kind of material it is but it’s very good. It looks less much “cheap” than with a sticky and smelly plastic bag. It has more of a “premium” feel to it and I really like that. Inside, the onahole was in PERFECT condition without any marks, tears or something.

The useless stick of Magic Eyes most favorite lube was still there though… shitty quality like always, please don’t use it because your experience with the onahole will be horrible. Take something like Ubujiru ~ Cr4zyDuck instead !


The molding of the Big Rina is truly good regarding the quality. The material is incredibly nice and smooth, not sticky and with no factory smell. Most of the work was clearly done on the pussy itself, I have to admit that it looks so good that simply by looking at it I can already feel a growing bowner in my pants !

Not as much details have been added to the rest of the body though, which looks rather plain. That’s a bit disapointing, I would have loved to see the same kind of details and quality brought up on her loli chest with details pinkish nipples for instance.

I don’t really understand the meaning of adding the AG+ logo on her side but anyway, Magic Eyes like doing this with most of its product anyway…

Here we can clearly see how much bigger the new Rina is comparated to the former one. Personnaly and regarding my own size, the Big Rina is just what I need in terms of lenght without risking of breaking it at the bottom.

But one of the most distinctive change beside the size remains to me the impressive weight difference between the two. The original was beneath 300g and now the newer version is exactly 600g !

That added material truly enhance the whole experience, and for the price you pay it’s a really good thing.

The material used is the famous AG+ from Magic Eyes, which is antibacterial. It keeps the product clean and fresh while the feeling to the touch is incredibly soft and “Puni-Puni” like !

The insides are completely double layered which makes her vagina look super cute and exciting. The entrance of her pussy is, as suggested by the title, an amazing and super exciting camel toe opening.

As a lolicon, I can assure you that seeing something as beautiful as this truly makes my mind shivers in excitment.

Regarding the structure, it’s quite simple actually with mostly small ribs all along her vagina up to her tiny womb which in the opposite is filled with little dots.

The entrance of her pussy looks super cute and exciting, the molding is truly perfect and I feel like on this particular onahole, Magic Eyes truly succeded in reproducing in details a loli labia.

Camel toe pussies looks so cute !

And so exciting once you spreak them to discover those wet, hot, tight and cute pinkish insides !

On this onahole, the “Kuu~Paaa” gimmick (which is the Japanese way of imitating the sound of a pussy being spread open) is truly at its peak ! I mean, most onaholes from Magic Eyes are created with camel toe like this, such as Sujiman Kupa Cocolo, Sujiman Kupa Lolinco Virgo or Gokusai Uterus. But on the Big Rina… damn spreading her open like this truly brings a urge of blood in my crotch so much it looks exciting and beautiful !


The sensations from this loli pussy on your rock-hard cock are honestly pure awesomeness ! All the ribs are offering a very good stimulation on all the parts of the penis without being over stimulating. Her vagina is quite straight with no twist and bump so you can actually fuck her at quite a quick path. Regarding the womb, you can’t feel yourself digging your way in her most precious part (too bad) but it’s still nice since it create a great vacuum.

All that coupled together results in a very enjoyable experience with this toy ! Maybe not as good as my favorite hand onahole, the Sujiman Kupa Lolinco Virgo, but it still worth a try =)


Well, it’s always the same trick on this part so at every review I feel like I’m always repeating myself on the same points… but yeah rince her with water, dry her insides with a microfiber towel and if you want extra softness on her outside add some talcum to get her all smooth !


I remember the orginal Sujiman Kupa Rina really had a huge impact on me since it’s actually the product that got me addicted to onaholes ! But I didn’t know such a bigger version could be this good and enjoyable to use, even after 2 years. To me this onahole totally worth it. With it’s large scale and depth, I guess Magic Eyes definitely aimed it to foreigners which are known to be larger than Japanase man. And that’s totally fine since that’s how my former Rina got broken…

If you are looking for a durable onahole with amazing feeling and quite large proportions, I would definitely suggest to give the Sujiman Kupa Big Rina a try !

  1. I feel that the inside of my Onahole Rina doesn’t seem as durable as it should be due to some Onahole parts. Began to peel or tear from the silicone. I’m not sure if my cleaning process is the wrong way or too harsh. Because I use a microfiber cloth to wipe the inside of the Onahole like every time I finish my activities and after rinsing.

  2. not gonna lie, I’m in basically the same boat; regular Rina was my first onahole and eventually upgraded to *big* Rina… only problem is i guess i did something wrong (probably trying to lube up with precum) and got some splits near the entrance lol (as long as I keep her clean, it’s no problem, but still)

  3. Can you advice me a onehole that I can feel everything inside.I prefer oneholes which made firmer materials. Thank you from now!
