It's been a while since I've seen an A-One male masturbator . I ordered the Fella male masturbator , which has a built-in suction unit. I've tried several suction units of this type before, but most of them were just so-so and didn't really impress me. However, I bought this one with a faint hope that the performance might have improved.

In terms of shape, it has lips, a tongue, and teeth, following the standard structure of the Fella male masturbator , but the interesting point is the addition of a suction unit embedded inside, and how that affects the level of pleasure.

It has suction and vibration, with 12 patterns for each, for a total of 144 possible combinations. I doubt anyone would actually use all those combinations, but the strength of the vacuum is certainly something to consider.

In the mature Fella male masturbator market, will this new suction unit make a significant impact? Let's take a look.

It's wide at the front and narrows towards the back of the throat. The way the back of the throat constricts due to the suction unit is very erotic.

How soft is Nodo Goshi Namarachio ?

List of hardness levels for Hot Powers materials

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 ability to convey the difference in hardness of materials neatly categorized as Hot Powers .

I possess all hardness levels except for "Oni" (demon), so I will try to convey that this male masturbator is close to that hardness. Even with this method, the toughness and properties differ depending on the material, and the feeling when kneading changes slightly depending on the size of the material, so I cannot say for sure whether I can convey it accurately. I hope you will consider this as just one reference.

The material has a medium hardness, neither too hard nor too soft, and felt about the same as Hoppa's standard 0. Therefore, the hardness isStandard 0I think that's quite reasonable.

Size of Nodo Goshi Namarachio

Regarding the comparison with dildos, I stopped using the dildo I had been using and tried three new 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 dildos come 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're using as an S size might actually be the old Michinoku M size.)

Administrator Review

At 7.56 in (19.2 cm) and weighing nearly 1kg, it feels quite heavy when you pick it up. However, because it has a cylindrical suction unit inside, it's easy to hold firmly and move around with one hand.

The material is chewy and highly elastic, with a medium hardness that's either standard or slightly firm. It has no noticeable odor and hardly any oil bleed, making it a smooth and pleasant material to the touch.

The entrance has the standard structure of the Fella male masturbator , with lips and a nose. The nose seems a little small, but the lips are about life-sized and beautifully colored. There are also teeth on both the upper and lower jaws, made of a slightly harder, different material.

The lip is about 1.30 in (3.3 cm) wide, so it's wide enough to fit even a semi-erect penis. I like to push in a semi-erect penis and let it grow bigger inside, so the size of the Fella male masturbator is ideal.

I immediately pour on some lotion and press my semi-erect penis against her lips. Feeling the soft sensation of her lips, my penis slides in smoothly. Soon, her soft tongue is waiting, gently welcoming the head of my penis.

First, I'll use it as is, without the suction unit. While enjoying the sensation in my mouth, once it's fully erect, I try to push it to the back of my throat, but it doesn't go in easily.

Pull it out once, make sure the lotion is thoroughly spread to the back of your throat, and then reinsert it. This time it will stop at the throat ring, but if you apply force, it will slide smoothly to the back of your throat.

The opening beyond the throat is narrow, but there are no rough bumps or protrusions; it's smooth and feels like a narrow opening. I like a relaxed feel, but I was surprised by how good the texture of the material was both inside the mouth and at the back of the throat, and how realistically it recreated the feeling of the inside of a mouth.

Having enjoyed the feel of the device when it's not powered, let's now activate the suction unit. Press and hold the power button, then press the button with the lip icon to start the suction unit.

The suction doesn't have a very wide stroke; it sucks in a few centimeters at a time, then releases, and the pattern changes each time you press the button on your lips. There are 12 patterns, but honestly, they all seemed pretty similar.

Rather than stroking while suction is active, I enjoy stopping the strokes occasionally to enjoy the suction. If I don't push it in all the way, I can stroke while suction is active, but if I push it in too far, I lose the ability to suction and it stops sucking. Suction takes some getting used to, but once you get the hang of it, it's a nice touch.

There's also a vibration button, and pressing it transmits vibrations inside. The vibration is the same type as male masturbator , which has had a small rotor embedded in it since ancient times. To be honest, I doubt this alone would increase the pleasure. In my case, the lack of vibration makes the male masturbator feel more realistic as a fellatio device, so I hardly ever use this.

Personally, I love the feel of the tongue; it hardly gets caught inside, moves smoothly, and has a gentle licking sensation that feels great. Applying lotion to the lips as well makes them feel moist and mucous during strokes, which greatly enhances the realism, so I recommend it. With plenty of lotion in the narrow throat area at the back, you can enjoy deepthroating, and the sensation was very pleasurable.

Regarding the teeth, I didn't experience any pain. Some people find them bothersome and remove them, but in this case, they also act as a stopper for lotion leakage, and they don't cause any discomfort during stroking, so I think it's fine not to remove them.

The suction unit could have been even better if it had a wider suction range, but the male masturbator ability to recreate the inside of the mouth is simply amazing, and even without considering the suction, I think the male masturbator is a very well-made fellatio device.
