Bun

Extremely soft, yet more stimulating than a lot of other ultra-soft toys out there.
It really leans onto that box art fantasy with how squishy, stretchy and springy it is.
This is also one of those toys that's able to be flipped inside out for easy cleaning and drying. Despite it being ultra soft it does seem to be pretty durable.
If you like soft toys, this is definitely one to try out even if you don't care for the slime girl tag.

If you're looking for something to edge with or want to really work for your climax this is it. Otherwise, you might wanna consider something else.

The entrance is really large, which has the pro of being easy to insert and get going if you're not rock hard, but a lack of any grippy feeling.
The rest of the tunnel is deceptively a low level of stimulation. The texture itself seems intense but due to how soft the toy is, it gets mellowed down a lot.
The toy's weight bundled with its softness does give a nice impact feeling, and an overall soft hug feeling.

Between the three onaholes in this series, I definitely prefer 2 but I dont think 3 is bad by any means.
The mirrored texture is pretty great, it leans towards the medium-softer side, and for a smaller onahole it packs a punch. Durability is better than average, especially for holes in this weight class, but that is the case with all of Hotpower's toys.
The one thing I wasn't sold on though is the weird ending to the tunnel. It kinda just stabs your head. Still feels good but I would prefer something more usual or nothing at all.
That said if the images of the internal texture interest you I would recommend it, if not I would take a look at the 2nd one in the series instead.

Preface, I've never used an actual cock ring, but I have used another cock ring onahole in the past.
My member is on the small-medium side, so those of you more well-endowed might have a different experience.

The distance between the opening and first ring is a big plus, letting the toy fully envelope you as a normal onahole rather than focusing on just the cock ring aspect.

The first ring is the most aggressive mostly due to the position, while the other two are kinda just there. With all 3 rings it's more like a firm pinch rather than a tight chokehold.

Aside from the entrance, the overall experience feels a lot more linear/uniform than the concept lets on.
The texture is entirely uniform, and overall material is relatively medium-soft level of hardness, which pairs well with the aggressive stimulation of the cock rings. It gives the toy a unique medium-hard level of roughness.

The size and shape is also a nice design aspect. It's bottom heavy while still giving a nice amount on top to hold onto. The 500-600g range is a sweet spot for all onaholes imo. it's enough to feel an impact while not feeling like your spending money on material that doesn't do much.

As for durability, I'm only like 6-8 uses in, but with the large opening and the cock rings, seems like this toy will last a lot longer than most others. Cleaning is also very easy, there's no deep nooks and crannies its a fairly straight tunnel that's easy to reach into and dry out.

This is a unique one for sure.

The main "Ultra Soft Zone" is very aptly named.
Despite what the texture looks like, it feels like fucking a cloud. The outer layer also pretty soft on its own which gives the toy very little structure. Just holding it, this whole part of the toy flops like an empty glove with how soft the materials are.

The 2nd "Normal Zone" is still a pretty soft material, as is the same with all Hatopla (formerly G Project) toys. But with how insanely soft the first zone is, all the stimulation focuses down to this point. The small length of this portion also makes it function only as either a glans massager or a pseudo anime-style uterus chamber.

If the toy was trying to replicate an anime fetish, it would be like a boob job + licking scene.

Cleaning is pretty straightforward, although drying that spiky ultra soft layer can be a little tricky. It's by no means difficult but definitely a trickier than your average toy.

For you ULTRA-soft enjoyers out there I would recommend this one. But even if you're just into regular soft toys I would say maybe skip this one.
The lack of stimulation can make you really have to work for your climax. But that can also be a good thing if you're looking for a "long-distance" toy.
