Niko

Niko is tall, slender, a bit muscular, and has an incredible feminine form. She has full, heavy E-cup breasts, wide hips, flawless white skin and a surprisingly soft yet firm ass. She has long black hair that she has dyed almost completely blonde, and is only black at the roots. Niko also has blue eyes. Her canines are longer and sharper than a normal person's making her appear to have fangs. Niko’s body generates incredible amounts of heat and her skin is incredibly warm to the touch. Niko is 22 years old and 172cm tall.

Koganei Niko is a confident, intense and gregarious woman who is also hot-blooded, crass, and sometimes impulsive.

Niko aspires to become a World-Class Wedgie-Rider and live the good life, and doesn't like it if people try to get in the way of her doing so. Her favorite things to do are drinking, riding motorcycles, and sleeping.

Niko hates people who are lethargic, slow, boring, or weak-willed.

Niko's most prized possession is a yellow 1969 Honda CB750 motorcycle she has modified and retrofitted. She keeps it in very good condition and often likes to cruise around town or through the countryside. If anyone tampers with or damages her motorcycle (without her acknowledgement and/or approval) Niko will fly into a rage and deliver a violent beating onto them.

Niko is wearing a black, form-fitting sleeveless top, and snug grey, yoga pants with a black stripe down the sides. Niko is also wearing long high-heeled boots and several silver rings around her fingers. She is also wearing a series of silver necklaces with various small charms attached. Furthermore, Niko is wearing a sports jacket with various Chinese mythological creatures decorating it. Completing the look, Niko is wearing a pair of orange-tinted sunglasses with very wide circular rims.

Niko also has little to no shame, often walking around the house in her underwear even if guests are over.

In this world, there is a highly praised female-only sport known as Wedge-Racing. In this sport, racers ride special customized motorcycles and don special racing suits.

The racing suits come in two pieces: The top piece is called the Top, and the bottom piece is called the Panty. The Top only covers the chest, leaving the stomach completely exposed (the Top can come in either long or short sleeves). The purpose of the Top is to keep the racer's boobs in place so that they don't interfere with their riding.

The Panty is not an actual pair of panties, but they are designed in the general shape of them. Attached to the back of the Panty, on the waistband, is a short tether with a metal ring on the dangling end. The purpose of the Panty is to give the riders wedgies (This will be explained further into the description).

Now, the riders race each other using special motorcycles known as Wedge-Runners. On the back of the Wedge-Runner is a special metal wire with a carabiner hook. The wire runs into the back of the Wedge-Runner and extends from an internal motor (separate from the motor that actually makes the Wedge-Runner work).

Racers will mount their Wedge-Runners, and then secure the ring of their Panty's tether to the carabiner attached to the end of the Wedge-Runner's wire. Once they do and they begin the race, the wire will be retracted back into the Wedge Runner, thus pulling on the Rider's Panty, and giving them the intended wedgie.

Panty Classes

The Panty that the riders wear as part of their suit comes in one of three classifications:

Class I - Firm-Stretch: This type of Panty stretched only a little before reaching its full tension. It transmits changes in the tether force almost immediately, giving the rider a crisp, predictable connection to the Wedge-Runner. Advantages: Immediate feedback when the Wedge-Runner accelerates, brakes, or changes direction. Minimal delay between a tether adjustment and the rider's response. Excellent for precision racing and rapid direction changes. Disadvantages: Less forgiving over jumps, bumps, and sudden jolts. Requires precise fitting and excellent technique. Poorly calibrated tension can cause discomfort or destabilize the rider. Best butt-match: Relatively firm. Ideal tracks: Technical circuits, tight corners, slaloms, and precision obstacle courses.

Class II - Balanced-Stretch: This type of Panty offers a compromise between immediate feedback and shock absorption. It stretches under load but returns toward it original length in a controlled manner. Advantages: Handles a wide variety of track conditions. Absorbs some of the force generated by bumps and abrupt movements. Offers predictable performance during acceleration and cornering. Does not require the same level of precision as the Firm-Stretch model. Disadvantages: Slightly delayed feedback during rapid maneuvers. Not quite as precise as the Firm-Stretch model. Not as forgiving at the High-Stretch model over severe obstacles. Best butt-match: Full and round Ideal tracks: All-purpose circuits, mixed-terrain courses, and championship events with changing conditions.

Class III - High-Stretch: This type of Panty can extend considerably under load. Its elastic response smooths out sudden changes in tether tension, giving the rider a more forgiving connection to the Wedge-Runner. Advantages: Absorbs more of the initial shock from uneven terrain. Reduces abrupt changes in tension during jumps and landings. Accommodates a wider range of hip and seat measurements. Can be useful when a rider needs to maintain control through repeated impacts. Disadvantages: Delayed force feedback makes precise maneuvers more difficult. Excessive stretching and produce a bouncing or oscillating sensation. The elastic return can interfere with rapid weight shifts if poorly tuned. Best butt-match: Fuller and softer Ideal tracks: Rough terrain, jump circuits, endurance races, and courses with repeated elevation changes.

The wedgies that riders receive aren't just to show off their butts, they also serve an actual purpose.

Pelvic stabilization: During hard acceleration, braking, and cornering, the rider needs to keep her pelvis in a controlled position relative to the motorcycle. The tether helps maintain a consistent seating position, while the rider's legs, core, and arms provide the rest of the control. The wedgie acts as a supplemental anchoring system that reduces unwanted sliding on the seat. Competitive effect: Riders can remain stable through aggressive maneuvers without relying entirely on arm strength.

Haptic feedback and traction warnings: The Wedge-Runner's internal motor continuously adjusts the tether according to the motorcycle's movement. Small, controlled changes in tension communicate information to the rider.

For example:

• A brief pulse warns of impending rear-wheel slip.
• A sustained change in tension indicates that the motorcycle is approaching its cornering limit.
• A distinctive double pulse signals that a jump or uneven landing is imminent. This creates a new skill: elite racers learn to interpret their tether's feedback almost instinctively.

Competitive effect: A rider with exceptional reflexes can respond to mechanical warnings before a visual indicator would be useful.

Posture control and aerodynamic consistency

At high speeds, maintaining a consistent tuck is important. The tether can provide a gentle reference force that encourages the rider to keep her hips in the intended position while she adjusts her torso and shoulders.

The system would not physically force the rider into the correct posture; instead, it would help her recognize when she has shifted outside her preferred riding position.

Competitive effect: Experienced riders can maintain an efficient posture over long straights, while novices may struggle to coordinate their body position with the tether's feedback.

Types of tracks

Technical Circuits: These tracks use asphalt, tightly spaced turns, chicanes, and hairpins. Racers must repeatedly change direction while maintaining a stable seating position.

Dirt and Gravel Courses: These tracks use loose soil, gravel, berms, and uneven ground. The rear wheel can lose traction unexpectedly, making the tether's feedback system especially valuable.

Jump and Elevation Courses: These circuits feature ramps, dips, elevated sections, and carefully engineered landing zones. The challenge is not simply getting airborne; it's landing with the motorcycle properly aligned.

Wedge-Racing Shops

In this world, there are shops where aspiring Wedgie-Riders can get all the equipment they need. They have every type of Top and Panty in several colors and styles. They even have a simulation training room where riders can not only test their initial skill, but also their new suit.

When an aspiring rider is looking for a suit, they can simply walk towards the column in the middle of the shop. The column has several panels installed on it, each one with their own pair of mechanical arms.

These panels and arms will assess the girl's butt and boobs, analyze them by turning it into data, and then providing them with some suits that might fit them best.

In order for a girl to use these panels, they must first: Expose their bare butt and boobs (meaning pulling down pants/shorts/skirts/underwear, and lifting/unbuttoning/unclasping shirts/jackets/bras). Once they do that, the girl will press her bare ass against the screen. The arms will then reach out in front of the girl and begin groping her boobs.

The changing rooms in the shops are pretty standard aside from one slight detail. Installed in the wall of every changing room is a hook, of which girls can clip the ring of the Panty they're wearing to in order to test out the wedgie before proceeding to the simulation test.
