It's been a while since we've seen RIDE , and this time it's Baby Touch , but instead of a single layer, it's male masturbator which has a point two-layer structure with firm material embedded in it.
While RIDE uses a two-layer design, male masturbator seems to use Baby Touch more often than Bungee Touch . Perhaps the two-layer adhesion is better with Bungee Touch than with Baby Touch .
The structure is perfectly positioned to target the underside of the penis, with plates arranged in a way that seems designed for that purpose. The red material is a hard-touch material, and the processing is quite spiky, so it might be a highly stimulating product that would make even fans of mellow hesitate.
So, what kind of performance can we expect from RIDE 's long-awaited two-layer point boost structure? Let's take a look right away.
Cross-sectional view and internal structure of Kaiiki Kakusei - Brush Upper
The hole is straight-through structure , and there is no Pump Area at the back, making it flat. The entire wall surface is covered with very finely carved and deeply engraved folds , and two firm material and nubs plates are placed at the bottom.

The inside is very snug, and the stimulation from the entire surface of the penis being rubbed by folds and nubs is quite intense. firm material and nubs are pointed, and there is also a prickly sensation like feel to them.
This is point dual-layer structure , with the nubs plate positioned on the underside.
Two nubs plates, each 1.77 in (4.5 cm) long and 8mm high, are placed side by side.
The nubs plate is 0.51 in (1.3 cm) wide, so it stimulates the entire underside of the penis by rubbing against it.
I tried tearing it open. The nubs plate is arranged in a double configuration with a space in between.
I cut it into quarters. The flesh is thin and it looks like the inside is quite dense.
Detailed images of Kaiiki Kakusei - Brush Upper
It was in a plastic bag and the code blister case was not present. There was almost no oil residue on the plastic bag. The weight was 0.90 lb (407 g).
It's a long size at 6.69 in (17 cm) in length, but its body is quite slender.
It has a round opening inside the folds that resemble female genitalia. The opening diameter was approximately 0.39 in (1 cm).
The narrow inner diameter provides a very tight fit. firm material plate, combined with nubs plate, creates a piercing sensation similar to prickly sensation , resulting in a fairly strong stimulation.
The vacuum was quite strong, and it effectively removed the air, giving a satisfying suction effect.
How soft is Kaiiki Kakusei - Brush Upper ?

List of HOT POWERS material's hardness degree
When trying to convey the softness of a material, simply saying "soft" or "hard" is difficult because everyone has different standards. As an experimental attempt, I would like to use the power of materials categorized by degree, such as HOT POWERS , which are neatly separated from hardness , to convey the feeling.
I own all hardness grades except for Oni, so I'll try to explain that this male masturbator is similar to this hardness . Even with this method, the stickiness and properties differ depending on the material, and the feel when kneading changes slightly depending on the size of the material, so I can't say for sure if I can convey it accurately. I hope you will consider this as just one reference.
I compared it to male masturbator (Butterfly Rail Ageha), which is made of the same RIDE material as the Bungee Touch . The texture of the Baby Touch material is moister, while the Bungee material is drier. The softness seems to be about the same.
I also compared it to the degrees of HOT POWERS Standard 0 (hardness level) , hardness , and it feels like it's the same as hardness . Therefore, the degree of hardness isStandard 0 (hardness level)I think that's quite reasonable.

Size of Kaiiki Kakusei - Brush Upper
In comparison to dildo , I stopped using dildo that I was previously using and tried the new 3 sizes.
The previous L size was impossibly large, so I figured it wouldn't be helpful to many people. Therefore, I've prepared three more realistic sizes.
Michinoku Dildo comes in various sizes, and even the M size can vary considerably. Please note that the sizes displayed here are not the actual product sizes, but rather our own arbitrary size translations. (For example, what we use for the S size is actually the old Michinoku M size.)
Compare the size of each dildo model.
With the S size, there's still plenty of space at the back.
Even the medium size has a little space at the back. However, it's thin, so you might find it lacking in thickness.
Even the large size has a small amount of space left, so it doesn't seem like it will reach all the way to the back.
Administrator Review
The material is the Baby Touch material, which we haven't used in a while. It has a moist, skin-like texture. The softness feels almost the same as Bungee Touch , but the body feels unusually slender when you hold it. That's because, although the weight is average at 0.90 lb (407 g), it has a long 6.69 in (17 cm) body.
As the name Brush Upper suggests, it's male masturbator specifically designed to stimulate the inner ridges from below, and the inside contains firm material is a variation of Partial dual-layer . firm material is divided into two plate-like sections and attached deep inside to ensure it makes contact along the inner ridges.
The entrance is a round hole about 0.39 in (1 cm) in diameter, and you can immediately see the red firm material inside. Even though it's called firm material , it doesn't feel much different in softness from the outer Baby Touch .
I immediately poured lotion inside and inserted it. The inside isn't that wide, and since firm material is already inside, I made sure to get a full erection before inserting it. Immediately, I felt prickly sensation from below, and I could feel the plate-shaped protrusions firmly pressing against the underside of my penis as I inserted it.
It's not exactly painful, but the prickly sensation sensation on the underside and the tightness inside are quite pronounced. The walls have a deeply carved, jagged folds texture, and when combined with the firm material protruding plate, the overall sensation feels quite intense.
What's really bothersome is the lack of thickness. It felt thin when I held it, and even after actually inserting it, it felt too thin and lacked thickness. It provides a good level of stimulation, but it's a bit monotonous, and it quickly becomes boring.
If you remove the air properly, the vacuum creates a tight seal and you can feel it clinging to you. Applying the vacuum makes the stimulation somewhat milder, but I don't feel it significantly increases the pleasure.
Turning it inside out was no problem, and the two layers of adhesive were firmly attached, so I think male masturbator has very high durability. However, I felt that male masturbator just needed one more deciding factor!
