A particularly popular attachment is the saddle-fixed posture aid rod. Inserted and attached to the vagina, it allows the rider to maintain a posture suitable for riding. They are well-received for their ability to feel the bumps in the road and ride comfortably.

You can choose the size that best suits your needs.

Size S. For beginners. Allows for posture maintenance without a large presence.

Size M Fills to the depths of the vagina to maintain good posture. Although it is considered a common size, it is effectively a Novice size as a more satisfying size is preferred.

Size L The bulging upper half presses against the womb, and the vibration is strongly felt while riding. Many users say they get a pleasant sensation with each pedal stroke.

XL size The largest size among the auxiliary rods. It pushes and spreads the womb and brings a strong sense of pressure. Even the slightest shock causes a direct pressure to be transmitted directly to the womb, resulting in a strong sexual sensation during the entire ride. Experts prefer to use this size.

After School


Kunoichi Ninja Costume

The most important aspect of a ninja’s infiltration and combat is the way they carry themselves. The most important thing for a ninja in infiltration and combat is to be able to move without hindrance, and the minimum amount of protection is necessary.
Ninja gear is also designed to be as portable as possible so as not to be bulky and to not obstruct the movement of the wearer, and so as not to block the hands.
They are also designed to be able to have even more armaments by means of equipment unique to kunoichi.

  • Head: She wears a leather forehead patch to protect her forehead. The hairpiece can be used as a blindfold.
  • Wrists: A leather arm armor is attached over a thin fabric that sticks snugly to the skin, on top of which is equipped with a bitter and smoky ball. On the opposite arm is a long, layered arm armor, which is used as a shield in battle.
  • Chest: The area is protected by leather armour on the arms, with an iron armoured plate applied to the centre of the chest. No fabric is attached to the front of the body to allow for quick movement.
  • Lower abdomen, intertrochanteric region: The movement of the ninja is rooted in the movement of the legs and feet. As these are parts of the body that are subject to intense behaviour and movement, they should be kept as open and smooth in movement as possible.
  • Legs: A belt for attaching weapons is wrapped around the thighs, and a cloth is wrapped around both knees to prevent chafing. Iron armor is attached to the shins of one leg, and the arm and leg armor can protect the whole body when the posture is adjusted.
  • Ninja outfit designed exclusively for kunoichi
  • Weight Chain: It is made somewhat smaller than a regular weight chain. Inserted in the nipple, they are easy to carry and can be pulled out and used on the spur of the moment. Although not heavy, it is powerful enough to be used with great force.
  • Stacked balls: Literally, a cylindrical stack of ball-shaped rings. Inside the cylinder are four iron cores with claw-shaped ends, and the ball rings are stacked on top of each other around these cores. Because there is no central core, important items such as scrolls can be stored inside the cylinders.
    The detached ball rings have a certain weight and can be used as a throwing weapon to great effect.
    Since each ring is of a certain size and weight, the entire tube would be inconvenient to carry. However, by inserting it into the vagina and carrying it, hands are free and it becomes less bulky. In addition, the ball portion bites into the vaginal wall, and the claws of the iron core pinch the anal opening at the back of the vagina, so it cannot be easily pulled out.
  • Connecting ironworks: A number of iron water chestnuts are joined together by a string to form a single string. The iron rhombi can be widely scattered by breaking free from the string in sequence. The thorn blade is not very sharp, but when weight is on it, a blunt blade is more effective as a stopper than a sharp blade ripping through it.
    As the utilisation of scattering rhombi requires a number of them, it is difficult for individuals to make them effective enough. However, as mentioned above, the thorns are not very sharp, so effective quantities can be operated by carrying a tetsubishi connected inside the anus and using a means of pulling it out when used.
    A single person can prepare a large enough quantity of scattering rhizomes to be used by several experienced kunoichi.
  • Poison Needle: Lightly armed and athletic, a figure may harm himself or herself if he or she carries a poison needle with a deadly poison. Therefore, the poison applied to the needle is not lethal. Poisoned needles are mainly used to disable an opponent.
    When this poison is struck into the body, the entire body is assaulted with intense pleasure and a constant feeling of climax. In addition, the sensitivity of the body is increased to the extreme, and the slightest stimulation causes a tremendous amount of pleasure. Those who are struck by the incessant climaxes are unable to even walk. During this time, they are involved in the seizure of secrets, escape, or interrogation.
    This poison also has the effect of improving bodily functions. Kunoichi use it not only as a poison needle but also as an enhancement drug, so the needle is attached to the clitoris, the part of the body that absorbs the poison best.
    Of course, the effect of the aphrodisiac poison causes intense pleasure. The poison absorbed at the clitoris brings pleasure to the body without limit, but Kunoichi is accustomed to this.

New Engine

A new first motorcycle engine model was introduced as a tourer motorcycle for women.
The I-4 engine installed in the new model is a high-horsepower, high-torque engine that provides torquey driving on all types of road surfaces. It has a wide power band, and shows powerful drive in all situations, including uphill, rough roads, and deceleration, as well as good response in acceleration and deceleration.

The I-4 engine was originally developed for heavy vehicles such as large trucks, and was designed for operation through a large-scale reduction mechanism. This engine has never been used in motorcycles because it does not provide sufficient braking for vehicles with small loads, and its controllability at high rpm is significantly deteriorated.
However, this drawback will be resolved and solved by a new mechanism created by a new idea.

The biggest challenge in installing I-4 engines in motorcycles is the lack of braking force at high output.
The new mechanism connects the power system to a large-mass piston at high RPM, and the braking force is obtained by operating this piston under load.
The most significant feature of this mechanism is that its design is based on the idea of using the passenger himself/herself as a means of obtaining the above-mentioned load.

The piston protrudes from the motor unit toward the seat, and the piston is installed in place of the seat. The passenger inserts the piston into the vagina and sits on the piston and leg seat to assume the driving position.

During operation in this state, the piston moves up and down while rubbing the inside of the vagina, and the friction is used as a braking force. The surface of the piston is carved with spiral stripes, and the convexity of the stripes is made to catch on the vaginal wall to create a greater frictional force.

Although the piston action is more intense at high output, such as when driving at high speeds, this product has become popular among female drivers because it provides a sense of speed and strong pleasure at the same time.


Training!

Vaginal Insertion Squat
A beautiful body resides in a well-formed torso and correct posture. This training aims to strengthen the core by quickly bending up and down while maintaining correct posture.

Vaginal insertion devices are used to maintain posture. By inserting and securing the device, effective exercise is possible without shifting the body’s position during flexion and extension.
It also brings about a naturally aligned posture because the equipment penetrates the center line of the body. Any blurring of the torso will gradually be corrected as you continue to exercise with correct posture.

As the body ascends and descends, the device rubs against the vagina, causing a load to be applied. Unlike gravity, the force is exerted only on the lower abdomen, and this force, which is applied while maintaining balance and posture, helps to strengthen the muscles necessary for a well-toned torso.

Furthermore, this training is characterized by a low load on the knee area. Quick bending exercises in a squatting position are hard on the knees because the weight is applied vigorously to the knees when bending over. In this training method, however, the head of the device is in contact with the back of the vagina, allowing the impact of bending to be released to the back of the vagina.

To increase the efficiency of training, it is effective to strengthen the fixation of the body’s centerline and reduce the blurring, i.e., to make the vaginal insert thicker.
The use of thicker equipment provides more resistance to the vagina during quick flexion and extension, making it an even more efficient workout.
The large size of the device easily reaches deep into the vagina and pushes up against the womb, so that most of the impact of even the most strenuous up-and-down movements is received by the vagina. This reduces the burden on the legs and allows for longer training sessions.

Many women who have a hard time sticking to exercise also get hooked on this workout.
Women who are intent on staying in shape train for longer periods of time using an instrument with a spiked surface that provides more resistance in the vagina.

Lascivious Swimsuit for Lascivious Women


Public Benches

Many simple benches with stakes for women have been installed in public places due to their space-saving features and low equipment and construction costs.
This bench has no backrest and, as the name implies, requires the body to be stopped by a stake to maintain the sitting posture. The method of stopping the body is not officially stated, but inserting a stake into the vagina and securing it is a commonly used means.

In recent years, public facilities have been aging, and many benches of this type have been in place for a long time.
One of the problems with aging benches, in addition to the loss of strength, is the encroachment on the pile sections.

Because of the intended insertion into the vagina, the stakes are coated with a water-repellent, corrosion-resistant coating. However, over time, the coating will wear off and vaginal fluids will seep through while being inserted into the user’s vagina.
Since the pile in this state is an extremely suitable environment for the breeding of bugs, invasion and breeding occur due to the movement of bugs that fly in from the outside or parasitize the user’s vagina.
The piles where the invasive bugs arise are colonies of bugs, and using them will almost certainly result in a parasite infestation of bugs.

Although there is a policy to review the installation of this type of bench due to the spread of parasites among users and the hygienic problem of inserting an outdoor installation into the vagina, there are many who wish to see it continue because of its “comfortable” feeling.
Among them, benches in an invasive state are preferred and used, and the renewal of equipment has been slow in coming.

Beachside Clubhouse

Cold tube
A tube made of metal material that conducts heat well, for the purpose of keeping cool during high temperatures. It is installed in outdoor seating areas during the summer season. The surface is composed of a material that does not get heated even under the blazing sun, so that it always feels cool to the touch.
It is designed to be inserted into the vagina for the most effective cooling effect, and its uneven shape provides a large contact area with the vaginal wall, and the slit holes carved into the body release the heat trapped inside the body.
For heat dissipation efficiency, it is desirable for the cold tube to be inserted as close as possible to the vaginal wall and to the deepest part of the vagina, so it is made in a size appropriate for this.
Due to its size and shape, when inserted into the vagina, pressure and stimulation of the vaginal wall and uterus will continue. In addition, inserting the tip of the tube into the uterus provides a higher cooling effect and stronger stimulation.

A type of worms that prefers cool and dark places and works in groups. It is found mainly at the seashore and rocky shores. Their body length is about 5 to 10 cm. They have sickle-shaped fangs in their mouths, which they use to hold their bodies in place when feeding or resting.
During the day, they stay together in groups and do not move much, but in areas where sunlight does not reach them, they actively peristalize. During the night, they spread out from their habitat to reach new suitable habitats.
Their diet consists mainly of seaweed and plankton, but they are also omnivorous, which is necessary for expanding their habitat. They can survive for some time in areas where food is scarce, and they store nutrients by consuming food in batches when they can acquire it.
When sufficient nutrition is secured, they reproduce en masse in flocks to increase the population. The eggs hatch in about three days and reach the same size as adults in about one week.

Because of their omnivorous nature, they can survive and parasitize within the human body. The most common parasites are vaginal and uterine parasites.
Most of the parasitic routes are through the vaginal insertion of open-air installations inhabited by smith crabs, and the colony inhabiting the installation moves directly into the vagina and lives there.
As soon as they move into the vagina, they begin to ingest nutritious vaginal secretions. In this process, the smelt bite the vaginal or uterine wall with their tusks to immobilize themselves and ingest the secretions, just as they do when feeding on prey in the past.
The sensation of being bitten by countless smith gopher tortoises is extremely significant and strongly stimulates the sexual zone. This sensation lasts for a long time until the hunger of the entire herd of individuals is satisfied.

Once nourished, the smelt begin to reproduce. The lightless, nutrient-rich vagina is an ideal environment for smolts, and the number of smolts increases rapidly.
Peristalsis and biting during predation become more frequent with each population, and while parasitized by the smith gopher, they continue to experience strong sexual sensations in the vagina at all times.

Quest


The art of lewdness and flesh-pot poisonings

One of the ninja techniques used by kunoichi.
The vagina is used as a flesh-pot, and poisonous insects are stuffed into it to prey on each other and produce a stronger poison.
The poisonous insects refined in a vagina filled with lewdness will produce a strong aphrodisiac poison, and this poison is used in various crafts.
Because it is difficult to preserve aphrodisiac poison, this technique is used to produce poisonous insects at the site where the craft is being made.

The technique uses ordinary poisonous insects collected locally. First, the insects are stuffed into a container attached to the waist and allowed to bite each other.
A cylinder, crafted with spines that bite into the vaginal wall and cannot be dislodged, is inserted into the vagina and connected to the container by a hollow stem. This keeps the highly poisonous bugs constantly entering the vagina.
When the number of bugs in the container decreases, new poisonous bugs are collected and put into the container. By continuing this process, bugs with stronger aphrodisiac poison can be refined.

The vagina, which is used as a flesh-pot, is constantly being poisoned by poisonous insects. The hungry bugs that enter the vagina bite and sting all over the area.
The poison of the bugs that has not been exposed to lewdness causes severe pain and damage to the vagina, while the poison of the bugs that has been refined and filled with lewdness causes more intense sexual sensations and climaxes.
The poison becomes stronger and the stimulation of the vagina becomes more intense as the refinement progresses over time.

Usually, the aphrodisiac poison used by kunoichi is strong enough to instantly incapacitate them if they are bitten by a single poisonous insect.
To refine it to this intensity, it is necessary to continue the technique for three days and three nights.
Toward the end of the operation, the surgeon’s fleshpots would be crawling with countless poisonous bugs of sufficient strength to bite into the vaginal walls and invade them with poison.

The longer the technique is practiced, the larger the poisonous insect becomes. Three days and three nights do not change the size of the venom much, and it takes more than half a month of practice to refine it to the point where the difference in size can be clearly seen.
The strength of the poison of the bugs that have grown up to that point is incomparable to that of the poison normally used, and just touching them will cause them to climax uncontrollably.
Of course, in the vagina of the surgeon during the purification process, the poisonous bugs of that strength will continue to rampage, bite, and stick their poisonous needles into the vaginal walls.

Training gym for women

A self-service gym specializing in equipment, it offers quality training at a reasonable price. The gym is oriented toward women and is equipped with many training machines optimized for women. The dedicated equipment is designed for women’s comfort and satisfaction, and has achieved a high level of efficacy and customer satisfaction.

We are proud of our continuity method. The most important factor in training is to continue to train. In order to keep our clients motivated, our gym is equipped with equipment that emphasizes satisfaction during use. Example: Lat pulldown machine
An ecstasy rod (sex rod) is installed under the seat in conjunction with the pull-down bar and pulley. The seat is made with an open space for the rod to pass through, and the rod is inserted into the vagina when seated.
The ecstasy rod is also extracted and inserted as the pull-down bar is raised and lowered, and the multiple layers of umbrella construction gouge the vaginal meat, gaining a reputation for providing a highly satisfying sensation during training. The range of motion of the bar is controlled by changing the stopper setting. By increasing the range of motion, the insertion stroke becomes deeper, making this machine popular because it motivates the user to train with a stronger sense of satisfaction.

Reasonable pricing with no cost
Our gym does not have unnecessary options or amenities found in other gyms. We have reduced costs by keeping the number of operating staff to a minimum and by not having instructors. We do not assign staff to clean the facilities, as many users have told us that this is unnecessary. We ask users to take care of their own sanitation. Before using the facilities, users are required to clean them to the extent necessary for their own use.
(*Most of the facilities are inhabited by parasites, but there are no problems with their use. Customers often find satisfaction in the sensation of wriggling parasites). This makes it possible to use state-of-the-art, popular, specialized machines at competitive rates.

Our original functional training wear
The clothes are specially designed to meet our methods, not to mention the moisture absorbency and breathability of the material. The upper body is a standard garment, but the lower body is open so that the vaginal area is exposed in accordance with our facilities. The strings crawl around the labia and are fastened together at the lower abdomen with metal fittings. While the normal wearing method provides comfort with the strings and fittings in contact with the clitoris, those seeking stronger and more satisfying sensations can attach the fittings directly to the clitoris. This is our recommended method of wearing the clasps, which pulls strongly on the clitoris during each exercise and provides a more than satisfactory sensation of satisfaction.

Caution

  • Our gym equipment may cause dilation or relaxation of the vagina, cervix, etc.
  • Due to the fact that our facilities are used by an unspecified number of people, there is a possibility that unintentional bugs or parasites may enter the vagina.
  • Please be sure to use the equipment in the correct manner. You are responsible for extending the range of motion of the machine inserts beyond the specified limits.
