Wow this one lives up to the name "hard"... The upper teeth really scrapes if you are into that sensation. The internal texture is super tight and corrugated, which makes it a bit tricky to dry as well. The hardness of the material is almost the same as the hymen in Sujiman Kupa Lolinco Extra Virgin.

I recommend this only to those who like highly stimulating texture and teeth sensations. Otherwise, I'd stick with the older versions

I bought this expecting extra tightness... but I'm not even sure if the plastic part in the middle exists? It feels like a regular blowjob onahole. It's not bad but considering the marketing I was expecting more.

When it comes to blowjob onaholes, I care the most about realism. So naturally, I rate very highly the Gokusen Fella series with the jaw mechanics. But unfortunately these have terrible structural durability, having tears at jaw joints and water getting trapped at every single crevice around the gums.

Okuchi Motion solves all these problems while maintaining the jaw gimmick. Because there are no joints, the jaw motion is now more fluid and it's less prone to tears. Furthermore, the teeth is made of soft plastic that is fused into the onahole material, which eliminates crevices entirely while also being less sensually invasive.

The best part in my opinion is the firmness of the mouth ceiling as well as the tightness of the throat. This realism more than makes up for the relatively dull inner texture.

Cleaning is super straightforward with a drying stick. However, the exterior gets very sticky for some reason, so powdering is a must.

The interior design is top notch quality and super tight. This I highly recommend. But as a result of this, it is super hard to clean & dry without potentially having a tear somewhere. If you care about proper maintenance, expect to invest at least 10 minutes for clean & dry...

The lube is on a thicker side, but it works very well for softer toys and does not dry quickly. Your Johnson will feel at peace with this lotion.
