A new product using SoftiTouch material has been released for the first time in a while, following RIDE ! And it's been a really long time since we've seen a product made solely from SoftiTouch material, rather than a composite material, like male masturbator .

RIDE "Fuwa Series" is a series that uses the company's softest Softie Touch material, and this latest product also clearly includes the word "Fuwa" (fluffy) in its name. This time, it adopts a "Yawa-oshi Push Structure" that incorporates jagged protrusions within a fluffy softness.

Looking at the promotional photos, it appears that the inside is lined with countless folds -shaped protrusions, a structure that would likely result in a highly stimulating type if it were made of a normal material. However, since this time it's made of a very soft Softie Touch material, I'm very curious to see what kind of balance of stimulation it will have.

For those who love fluffy and creamy textures, the latest addition to RIDE 's "Fluffy Series" is finally here. So, what kind of male masturbator has it turned out to be? Let's take a look right away.

The total length is 5.91 in (15 cm).inInsertion length: 5.12 in (13 cm)That is the case.

The interior is densely packed with folds protrusions, and the structure is designed so that you have to push your way through nubs to get to the back.

folds pattern is visible not only on the protrusions but also on the inner wall. Turning it inside out was not a problem.

Unboxing of the Fuwatsubo Mashumaron package.

The item was not labeled blister case and was in a bag. There was almost no oil residue on the bag. The weight was 0.91 lb (414 g).

The image showing the weight of Fuwatsubo Mashumaron displays 1.19 lb (539 g).

With a total length of 155mm, it has a slightly shorter body and a simple cylindrical shape, but the center is slightly shaped.

The entrance is a normal-sized round hole, about 0.51 in (1.3 cm) in diameter, and is located in a slightly recessed position.

The entrance size of the Fuwatsubo Mashumaron is 0.51 in (1.3 cm).

When it's only partially erect, the densely packed folds protrusions will push it back, so it's easier to insert if it's fully erect.

The vacuum effect gives a surprisingly pulling sensation, but the expected folds protrusion didn't wiggle around.

How soft is Fuwatsubo Mashumaron ?

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.

It felt slightly softer than the -2 hardness , and almost the same softness as the -3.

Similar to the previous Softie Touch material, hardness material is as follows:Very Soft -3I think it's around that rank.

Size of Fuwatsubo Mashumaron

Image showing the total lengths of the three types of dildo : S 5.12 in (13 cm), M 5.71 in (14.5 cm), L 6.10 in (15.5 cm).

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.)

When you place dildo , the S size has enough space for one glans (penis) , and the M size has a little space at the back. The L size will be completely filled, so you probably won't be able to fully enjoy it.

I tried installing Fuwatsubo Mashumaron onto the A10 piston SA.

This is what it looks like when you put Fuwatsubo Mashumaron piston into the inner case of the A10 piston SA.

The image shows Fuwatsubo Mashumaron being installed on A10 piston SA, and a finger being inserted into male masturbator to check the tightness.

Since it was slim like the Fuwa series, I thought it might fit in the case of the A10 piston SA, so I tried installing it. In terms of size, it fit without any problems and the size was just right.

However, when I actually used it, the inside was quite tight, and although it did move, I personally wasn't entirely satisfied. I think a type with a wider inner diameter would be a better fit for the A10 piston SA.

Review of the Fuwatsubo Mashumaron

The body, made of SoftiTouch material, has a simple cylindrical shape, but it tapers slightly towards the middle. While it's a standard size at 5.91 in (15 cm) in length and 0.91 lb (414 g) in weight, it does feel a bit slender when you actually hold it.

The oiliness characteristic of the SoftiTouch material is noticeable, though not to the point of being sticky. The smell isn't strong enough to permeate the surrounding area, but if you bring your nose close, you can faintly smell a petroleum-like odor. The body is so soft that your fingers sink into it, and it has a smooth, almost soft and airy feel.

The entrance is in a slightly recessed position and is a simple round hole. The diameter is a standard 0.51 in (1.3 cm). Now, let's pour lotion into it and start using it.

When attempting insertion while only partially erect, the opening widens, but the inside feels tightly packed, pushing back. However, once fully erect and applying a little force, it slides in smoothly.

When you move it slowly, you feel folds -shaped protrusions hitting you from all sides, and you feel a gentle rough, scraping sensation sensation from folds and firm, bumpy sensation sensation from nubs protrusions mixed together. In terms of the proportion of stimulation, it feels like folds accounts for 30% and nubs accounts for 70%, with firm, bumpy sensation sensation being felt more strongly.

Due to its short overall length, it's easy to handle despite its soft body, and its light weight allows for nimble movement. Occasionally, there's a feeling of catching on the nubs protrusion, but the sensation of stimulation doesn't change much, and the same firm, bumpy sensation sensation continues throughout.

When you apply vacuum, you'll surprisingly feel a pulling sensation deep inside. However, there's no significant change in the internal stimulation, and nubs protrusion remains as prominent as ever, making it undeniably monotonous.

The material itself feels soft and is not bad at all, but it's still not thick enough. In particular, the walls near the center, which are the source of stimulation, are thin, so it didn't feel as soft as gently enveloped , which I had expected from a Softie Touch material.

Overall, the inside is a bit tight, but there's no feeling of being pushed back during use. On the other hand, the nubs protrusion is constantly in contact with the area around glans (penis) , resulting in a type that feels soft and squishy, yet surprisingly provides a firm stimulation.

Even when turned inside out, the opening doesn't tear immediately, and the bottom has a decent thickness. Therefore, it seems that washing it inside out shouldn't be a problem.

Personally, I was looking forward to this new "Fuwa~ Series" product after a long hiatus, but it lacked the softness I was expecting from gently enveloped , and the variation in stimulation was also minimal, resulting in a rather disappointing product.

Fuwa~ Series

This series uses Softie Touch , the softest material in RIDE range. The hardness material boasts a softness that defies the conventional wisdom of previous manufacturer-made male masturbator products. It features a gentle, enveloping sensation similar to soft and airy , and is also highly elastic.

This series is targeted at fans of mellow , with the first part of the name being..."Ahhh"It has a tag attached. The packaging is also different from the usual male masturbator , using a horizontal type.
