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.

How soft is Kaiiki Kakusei - Brush Upper ?

A list showing the hardness degree of the HOT POWERS material.
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.

  • This shows a comparison of Kaiiki Kakusei - Brush Upper and Bungee Touch materials.
  • 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.

  • This image shows a comparison of Kaiiki Kakusei - Brush Upper , HOT POWERS , and Standard 0 (hardness level) materials.
  • 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.

  • Image showing insertion lengths of 3 types of dildo : S 4.53 in (11.5 cm), M 4.92 in (12.5 cm), L 5.31 in (13.5 cm).

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.)

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!
