The magical girl who protects the world has been trained.

In the mundane halls of A City High School, Miki lived an ordinary, monotonous life. She was an unremarkable girl, with average grades and few friends, yet she harbored a deep yearning for the legendary magical girls. Whenever news reported on evil organizations ravaging the city, she would secretly fantasize about transforming into a hero herself, wielding a magic wand against the forces of darkness. Shiya in her pink uniform, Ziyu in blue, and Lena in yellow – they were the city's guardians, with graceful figures and a valiant presence in battle. Miki often secretly browsed their combat videos during breaks, filled with longing. This day, everything changed. After school, as Miki walked home alone, a bizarre black wand suddenly descended from the sky, coiling around her wrist. It emitted a low hum, wriggling as if alive. "You have been chosen to be my master," a cold voice echoed in Miki's mind, "From now on, you will be the villain, to discipline those self-righteous magical girls." Miki froze, trying to shake off the wand, but it clung to her, unyielding. The voice continued, "Your mission is to obstruct them, to shatter their justice. Use me to transform all things into instruments of restraint, to make them submit." Miki's heart pounded. She had never imagined herself on the villain's side, yet a strange excitement surged through her. The wand seemed to be infusing her with some kind of power, subtly twisting her thoughts. Just then, her phone vibrated – a news alert: an evil organization had attacked the city center park, destroying public facilities and unleashing monsters. The magical girls had been dispatched. The wand's voice sounded again, "Go, stop them. This is your first mission." The park was located in the heart of A City, surrounded by dense woods and amusement facilities. It was already dusk, the last rays of the setting sun casting a glow on the lawn, but the air was thick with the scent of chaotic dust. The minions of the evil organization – a horde of monsters condensed from dark energy – were wreaking havoc, toppling benches, tearing up flowerbeds, and even twisting lampposts into grotesque shapes. Screams echoed as terrified citizens fled. Suddenly, three beams of light descended from the sky. Pink, blue, and yellow figures landed – it was Shiya, Ziyu, and Lena. They had transformed, their uniforms clinging to their shapely figures, their skirts fluttering gently in the wind. Shiya, wielding a pink longsword and specializing in close combat, charged to the front lines first, her sword light like a rainbow, severing the tentacles of a monster. Ziyu raised her blue scepter, releasing purifying ripples that dispersed the surrounding dark energy. Lena chanted spells from the rear, yellow magic bullets shooting out like meteors, precisely striking the monsters' weak points. "Everyone, hold on!" Shiya shouted, her breath coming in short gasps, but her eyes were resolute. She was tall, with graceful curves, her legs appearing especially long as she ran in her pink uniform. "These guys are getting more cunning. We can't let them harm innocent people." Ziyu nodded. As student council president, she was accustomed to leading, and now her blue uniform reflected the setting sun, the ribbon on her chest swaying gently. "Light of Purification, envelop all!" she murmured, and a blue light spread, slowing the monsters' movements. Her figure was well-proportioned, her waist slender, yet she exuded a steady strength. Lena smiled slightly. Her yellow uniform was adorned with lace, and her demeanor as the head of the arts club lent her an air of elegance even in battle. "Magic Barrage, bloom!" she commanded with a light flick of her finger, and dozens of yellow orbs rained down, exploding with a bang as monsters fell. Her figure was delicate, her movements possessing an artistic rhythm. The battle raged for twenty minutes, the magical girls coordinating flawlessly. Shiya's close-quarters combat neutralized the monsters' ambushes, Ziyu's purification prevented the spread of dark energy, and Lena's ranged attacks provided fire support. Finally, the last monster dissolved into black smoke under Shiya's blade. The park returned to silence, leaving only a scene of wreckage. The girls gathered, panting, checking each other for injuries. "Is everyone alright?" Ziyu asked, wiping sweat from her brow. Her blue uniform was smudged with dirt, but she still looked energetic. Shiya smiled and sheathed her sword. "Just minor scrapes. The enemy seemed weaker this time. Lena, your magic bullets were so accurate!" Lena shook her head, her yellow skirt swaying gently. "Don't get careless. There might be stragglers." She scanned the surroundings. Most of the park's amusement facilities were intact, including a carousel with wooden horses standing silently in the sunset. Just then, a figure emerged from the trees. Miki's heart pounded. She gripped the wand, its energy sending a warm current through her. "Now," the wand's voice urged in her mind, "transform the park's carousel into an instrument of discipline. Restrain them, toy with their bodies." Miki took a deep breath and stepped out of the shadows. She still looked like an ordinary student, her school uniform slightly disheveled, but her eyes held a new, peculiar glint. "Magical girls, you did well," she began, her voice trembling with excitement, "But now, it's my turn."

The battle erupted on the playground. Shiya, skilled in close combat, charged at Miki like a pink whirlwind, her fists and feet swift. Miki retreated a few steps, her magic staff flashing, transforming a paving stone on the ground into soft ropes, attempting to ensnare Shiya's ankles. Shiya agilely dodged, thinking: this girl's magic isn't destructive like the evil organization's, it's more like some kind of... restraint? She shook her head, focused, and continued her assault. Ziyu provided support from the rear, her blue purification waves attempting to weaken Miki's staff energy: "Lena, cover attack!" Lena nodded, yellow magic forming a wall of light, forcing Miki back. Miki laughed: "Interesting, you think this will win it for you?" She deliberately retreated to the edge of the flagpole stand, luring the three closer. The battle continued for several minutes, magical lights intertwining in the air, the grass on the playground trampled into disarray. Students watched from a distance, some taking out their phones to record, but no one dared to approach. Miki seized an opportunity. As Shiya launched a close-range attack, she suddenly sidestepped, aiming her staff at the three flagpoles and releasing energy. Purple light enveloped the flagpoles, instantly transforming them into three flexible pillars, their surfaces covered in invisible binding fields. "Now, taste this!" Miki whispered. Shiya's body was suddenly pulled by an unseen force, and she cried out: "What?!" Her arms were invisibly fixed to the first flagpole, her body stretched out, unable to move. Ziyu and Lena were caught simultaneously, Ziyu bound to the second, Lena to the third. They struggled, but the flagpoles' energy fields clung to their limbs like magnets, suspending them in mid-air, their toes barely touching the ground. "What kind of magic is this? Let us go!" Shiya twisted her body forcefully, her pink uniform clinging to her skin, the rise and fall of her chest betraying her inner panic. This was her first encounter with such restraint, and her body trembled involuntarily. The usually confident school beauty felt an unprecedented helplessness. Her sensitive skin registered the slightest air current, each struggle causing her uniform to rub against her skin, bringing a strange, tingling sensation. She tried to break free with her close-combat strength, but the energy field coiled around her like threads, restricting her movements. Mentally, she was shocked: why didn't this magic attack directly, but instead, this... playful torment? Ziyu's blue uniform stretched taut under the restraint, her tall figure elongated, her legs slightly parted. She, who excelled at purification, was unable to concentrate and release magic. "This... is too bizarre," she murmured, her voice trembling slightly. Being restrained like this for the first time, her mental defenses began to waver. The usual calm and collected student council president was now flushed, her sensitive areas exposed to the air. The energy field gently squeezed her waist, forcing her to take a deep breath, her chest rising. She tried to calm herself, thinking: I must find a weakness, I cannot panic. But her body's reactions betrayed her, each slight friction sending an unfamiliar itch crawling up her spine. Lena's yellow uniform swayed on the flagpole, her voluptuous figure making the restraint appear even tighter. "Hey, what are you doing? Let us down, now!" she exclaimed, her voice carrying the usual liveliness of the literature club, but now tinged with unease. As someone skilled in magical attacks, being stripped of her freedom of movement for the first time filled her with a mixture of fear and curiosity. Her skin was particularly sensitive, the energy field of the flagpole caressing her arms and legs like a gentle touch, causing her to tremble. She twisted her body, trying to escape, but only succeeded in pressing the fabric of her uniform closer to her skin, bringing an uncontrollable, ticklish sensation. Mentally, she recalled her days of reciting poetry, but now felt like an exhibited piece of art, both embarrassing and thrilling. Miki walked closer to the three, twirling her staff. She watched their reactions, the memory of the park from a few days ago making her even more excited. "Don't rush, the real show is just beginning," she said in a low voice, then pointed her staff at the grass on the playground. Purple light spilled down, and the ordinary green grass instantly changed. Each blade became soft and elastic, quivering slightly like countless tiny tendrils. They began to grow slowly, extending towards the flagpole stand. "What... is this?" Shiya's eyes widened as she watched the grass blades creep up her ankles. The grass, as if alive, gently coiled around her calves, beginning to tickle her lightly. This was her first experience with this kind of treatment, and her sensitive body reacted strongly. The tips of the grass blades brushed against her skin like feathers, from the soles of her feet upwards, bringing waves of itchiness. She bit her lip, trying to suppress a giggle: "Ah... no... this is too ticklish!" Her mind was in turmoil: as a close-combat expert, she should be strong, but this tickling awakened every nerve in her body, and the skin on her chest felt warm. She wriggled, her curves beneath the pink uniform swaying, her face flushed. The grass blades began to twine around Ziyu's waist, the tiny touches like fingers tracing her abdomen and sides. Her blue uniform couldn't block this gentle invasion, and the itchiness washed over her like a tide. "No... stop..." she pleaded in a low voice, a tremor in her tone. This was her first time experiencing such a treatment, and her purification abilities seemed to be disrupted. The sensitivity of her body made it impossible to concentrate. When the grass blades brushed under her arms, she finally couldn't help but let out a soft laugh: "Haha... so ticklish..." Mentally, she felt a mix of shame and [X], her usual elegant image crumbling in this moment, her cheeks burning, her eyes slightly moist. The grass blades were the first to climb Lena's arms, the tendril-like grass gently tickling her neck and behind her ears. "Yaa! This... this is torture!" she cried out, her body twisting violently. Her yellow uniform slid slightly with her struggles, her ample figure amplifying the ticklish sensation tenfold. When the grass blades swept across her back and inner thighs, her sensitive skin immediately broke out in goosebumps: "No... hahaha... I can't stand it!" This was her first time being tickled, and her mental defenses rapidly crumbled. The peaceful scenes of the literature club flashed through her mind, starkly contrasting with the current chaos. She burst into laughter, tears welling up, her body's reactions making her both embarrassed and unable to stop. Miki stepped back a few paces, admiring the scene. The energy from her staff filled her with satisfaction; she hadn't expected to enjoy this sense of control so much. The grass blades continued their dance, sometimes gently sweeping over the sensitive soles of the three girls' feet, sometimes coiling around their waists and tickling them. Shiya's laughter grew louder, her body beneath the pink uniform beginning to sweat, the tickling making her limbs feel weak: "Stop... please stop..." Her mind resisted, but her body's sensitivity made her respond involuntarily, each tickle sending an electric current through her entire being.

The studio audience erupted in applause, cameras flashing to capture their every expression. Viewers at home buzzed with excitement, these young girls' heroic deeds making them idol-like figures. However, just as the interview reached its [X], a figure quietly appeared at the entrance of the studio. It was Miki, an ordinary student from A City High School, holding an inconspicuous magic wand. Ever since being bound to this wand, her life had been turned upside down. It demanded she become an evil villain, and its power was to transform ordinary objects into tools of restraint and discipline. Her experience in the park last time had given her a taste of the [X] of sadism, the sight of magical girls struggling helplessly gradually taking root in her heart. Today, she chose this public venue, intending to expose their predicament to thousands. Miki took a deep breath, the wand glowing faintly in her palm. She whispered, "Let's begin." The wand's energy spread silently, first affecting the television station staff. Their eyes became vacant, their movements stiff, as if controlled by invisible strings. No one noticed the anomaly; the host continued to ask questions, but her voice began to sound mechanical. Suddenly, Miki raised her wand and aimed it at the dense network of wires on the studio ceiling—the cables for lighting, sound, and cameras. She concentrated, and the wand released an invisible wave. The wires began to twist and deform. They writhed like living creatures, descending from the ceiling and rapidly coiling towards the three magical girls. Shiya was the first to react, feeling a chill creep up from her ankles: "What is this?!" She tried to stand, but the transformed ropes had already ensnared her legs, pulling her ankles and wrists behind her, forcing her body to bend into a posture like a horse—the four-horse binding. Her pink uniform was pulled taut, revealing patches of skin, her heart racing as she felt this helplessness of being bound for the first time. As a close-combat expert, she was accustomed to free movement; now, with her arms pulled tightly behind her and her knees forced to the ground, her body trembled involuntarily. Psychologically, she felt a strange shame welling up, not the pain of battle, but a more intimate invasion. Ziyu followed closely, attempting to use purification magic, but the ropes had already coiled around her wrists, binding them to her ankles. She fell to the ground, her body arching beneath her blue uniform, trying to struggle: "Stop! What power is this?" Her body reacted intensely, being restrained like this for the first time, she felt the sting of her skin rubbing against the ropes, her chest heaving. As student council president, she always maintained her composure, but now, bound like an animal, the contrast flashed a hint of fear and an inexplicable sensitivity in her mind. Her skin began to feel hot, the tightness of the ropes making every breath carry a subtle friction. Lena was the last to be caught. She intended to unleash a magical attack, but the ropes fell from above, quickly pulling her limbs behind her. She knelt on the ground, her yellow uniform pulled open slightly, revealing her smooth shoulders: "No... this is impossible!" Her body experienced this disciplinary restraint for the first time, her sensitive nerves causing her to tremble involuntarily. As head of the arts club, she usually immersed herself in art, but now she felt an unprecedented sense of exposure, a wave of anger mixed with curiosity surging within her. The ropes tightened around her joints, each attempt to break free bringing a tingling sensation. Miki stepped forward, wand in hand, and watched the three girls being hoisted up. The transformed ropes lifted them from the ground, suspending them in mid-air, displayed like works of art before the cameras. The live broadcast did not stop; instead, the cameramen—now controlled by the wand—turned their lenses towards their predicament. Viewers nationwide saw the magical girls bound in the four-horse posture, their bodies swaying slightly, the curves beneath their uniforms faintly visible in the lights. Shiya's pink skirt was pulled up, revealing parts of her thighs; Ziyu's blue collar slipped, her shoulder line clear; Lena's yellow jacket was torn open, her waist bent into a graceful arc. "You... what are you looking at?!" Shiya gasped, her arms pulled behind her, her body suspended, each sway making her feel the pressure of the ropes against her skin. Her psychological defenses began to crumble, exposed so publicly for the first time, her cheeks flushed, the audience's gaze echoing in her mind. This was not the shame of battle, but something deeper and more sensitive, her body responding involuntarily, every point of contact on her skin transmitting like an electric current. Ziyu tried to remain calm, but the suspended posture made her breathing rapid: "Let us down quickly! This is live..." Her body reacted more intensely, the ropes chafing her joints, giving her a strange, ticklish sensation. Experiencing this disciplinary restraint for the first time, her heart pounded like a drum, her usually calm mind now filled with chaotic thoughts. The audience's gaze was like invisible tendrils, amplifying her sensitivity; she bit her lip, trying to suppress the heat rising from her lower abdomen. Lena twisted her body, trying to find balance: "Why isn't anyone coming to save us?!" Her yellow uniform was disheveled as she was hoisted, revealing more skin. Restrained like this for the first time, her nerves were highly sensitive, each pull of the rope bringing a subtle shiver. Psychologically, she felt a sense of humiliated [X] mixed in, which confused her. The live broadcast captured her every expression, her face flushed, her body's reactions making it impossible to deny the inner turmoil. Miki did not respond. She turned to the microphones on the ground, their jacks transforming under the wand's magic into small, faintly glowing clips. She picked one up and walked towards Shiya. Shiya's eyes widened: "Don't come near!" But she couldn't move. Miki carefully attached the clip to her [X] sensitive area and [X]. The cold touch of the clip made Shiya's body stiffen, followed by a slight electric shock. "Ah!" Shiya screamed, her body arching beneath her pink uniform. The electric shock was not excruciating pain, but a numbing stimulation that reached her nerve endings. Disciplined like this for the first time, her sensitivity was extremely high, a wave of heat emanating from her [X], her [X] feeling tingly as if lightly touched. She gasped, a wave of shame washing over her psychologically: "This... this feeling..." Her body responded involuntarily, her muscles twitching slightly, the memory of the park incident flashing in her mind, but this time it was more public, making her feel even more helpless. Miki turned to Ziyu and attached another clip to her. Ziyu shook her head: "Please stop!" As the clip tightened, the electric shock followed. Her whole body trembled, the curves beneath her blue uniform quivering. The stimulation from her [X] made her legs instinctively clamp together, but the ropes wouldn't allow it, and she felt a heat spreading from within. Experiencing this electric shock discipline for the first time, her sensitivity made her almost speechless, the numbness from her [X] spreading, her psychological defenses collapsing: "Why... am I so sensitive?" She tried to purify this power, but the wand's control left her powerless. Lena was the last. She watched Miki approach, her voice trembling: "Who are you? Why are you doing this?" After the clip was attached, the electric shock arrived as expected. She screamed, her body writhing beneath her yellow uniform. The stimulation of the electric shock hit her sensitive points directly, her [X] responding as if lightly caressed, her [X] sending waves of tingling. Played with like this for the first time, her nerves were highly alert, each electric shock amplifying her reactions. Psychologically, she felt a mixed sense of anger and a strange [X]: "This is impossible... I can't just..." But her body's tremors betrayed her. Miki stepped back a few paces, wand in hand, occasionally issuing a command, causing the clips to release intermittent electric shocks. The studio echoed with the gasps and moans of the three girls, the live broadcast faithfully recording it all. The audience stared at the screen in shock; some tried to call the police, but the television station was completely under control, all signals having been tampered with.

The three magical girls cooperated in perfect sync, Shiya engaging in close-quarters combat at the front, Ziyu purifying darkness from the rear, and Lena providing long-range support. The chaos in the dog kennel gradually came under control, members of the evil organization falling one by one as dark energy was dispelled. The onlookers began to applaud, and the dogs also quieted down. However, just as they thought victory was within reach, a figure quietly appeared. Miki hid in the bushes near the dog kennel, clutching the strange magic staff. Her heart had raced during their last encounter in the park, when she had transformed the park's carousel horses into BDSM equipment, restraining the magical girls. Witnessing their state had awakened something deep within her. Now, the staff whispered new instructions: "Use the items here to transform them into human-dog hybrids. Make them crawl in humiliation and experience the taste of submission." Miki took a deep breath. She had been an ordinary student, idolizing magical girls, but had been bound to this staff, becoming an evil villain. She hesitated for a moment, but the excitement within her propelled her forward. "Transform..." she murmured, and with a flash of the staff's light, her appearance shifted, cloaked in darkness as she infiltrated the battlefield. The three magical girls were panting, celebrating their brief victory. Shiya wiped sweat from her brow, Ziyu checked for residual dark energy, and Lena was tending to an injured puppy. Suddenly, a strange energy wave surged from the side. Miki raised her staff, aiming it at several chains and muzzles within the dog kennel. "Transform!" she commanded in a low voice. The chains and muzzles instantly twisted and warped, becoming tools to restrain the magical girls. Shiya was the first to react. She turned to Miki, "Who are you? Another member of the evil organization?" But before she could finish, a transformed chain slithered like a snake and coiled around her limbs. Her arms and legs were forcibly bent, knees buckling, wrists and ankles connected, forcing her to land on all fours. Her body trembled beneath her pink uniform, a strange tightness seizing her from the sudden restraint. Shock and shame flooded her mind – as the school's beauty, she was accustomed to being admired, but now she was forced to crouch like an animal. "What is this... Let me go!" Shiya struggled, shouting, but the magical power of the chains rendered her unable to break free. She tried to use her close-combat strength, but the bending of her limbs made her balance unstable, and she could only writhe on the ground. Her figure was already excellent, her breasts heaving beneath her uniform, her hips involuntarily arching in this posture. Her cheeks burned, and an unprecedented sense of humiliation washed over her, while her sensitive areas grew slightly warm from friction with the ground. This was the first time she had been trained like this. Although she had a similar experience in the park before, this canine transformation made her feel even more novel and sensitive. Every crawling motion amplified the sensation of the ground against her skin, as if every inch of her flesh was responding to this coercion. Ziyu was restrained shortly after. As she attempted to purify the energy wave, another chain wrapped around her. Her limbs were similarly bent, forcing her body beneath her blue uniform to kneel. Her tongue was suddenly fixed by a transformed muzzle, the tip gently clamped, only able to extend out of her mouth, unable to retract. Saliva dripped uncontrollably, forming small puddles on the ground. She tried to speak, but could only manage muffled whimpers. Ziyu's psychological reaction was more complex. As student council president, she had always been self-controlled, but the park incident had subtly awakened a desire for submission. Now, this canine restraint stirred her emotions – shame mixed with a strange excitement. Her body reacted intensely; the sensitivity of her clamped tongue made every swallow feel like a stinging [X], and as saliva dripped, her face turned crimson, her chest heaving. This was her first time being trained like this. The exposure of her tongue tip to the air made her exceptionally sensitive, as if every breeze was like fingers caressing her. "Mmm... mmm..." Ziyu tried to protest, but her voice was muffled. As she crawled on the ground, the bending of her limbs made every step difficult, her hips swaying beneath her blue uniform. She felt [X] slightly moistening due to the posture. The humiliating crawl brought back echoes of the previous incident, but this time it was more direct. Her body involuntarily responded, her sensitivity seemingly heightened. Lena attempted to counterattack with magic, but Miki's staff's energy enveloped her faster. A transformed muzzle was directly fixed on her mouth, her tongue clamped and protruding, saliva dripping. At the same time, her limbs were bent by chains, forcing her body beneath her yellow uniform into a low posture. Skilled in magical attacks, she was now unable to chant spells, only able to emit low whimpers. A strong sense of anger and helplessness surged through Lena. As head of the literary club, she was imaginative, but now she was being treated like an animal. She struggled to crawl, saliva leaving trails on the ground, each tremor of her tongue sending a current-like sensitivity through her. This was her first experience with this tongue-exposure training. The sensation on her tongue tip was exceptionally intense, as if surrounded by invisible stimulation, causing her body to tremble slightly and her cheeks to flush. Miki watched the three of them, a sense of satisfaction welling up within her [X]. She approached, her staff glowing slightly, ensuring the restraints were firm. "You magical girls always think you're so high and mighty. Now, experience what it's like to be tamed," she said in a low voice, her tone commanding rather than crude. The three magical girls were forced to crawl on the ground. The dog kennel floor was slightly rough, their uniforms brushing against the dirt. Shiya led the way, trying to guide them to escape, but the bending of her limbs made every step slow and humiliating. Her resistance gradually softened, and the sensitivity of her body made her notice the vibration of each knee touching the ground, transmitting through her entire body. Ziyu followed behind, her tongue still extended, causing her to drip saliva. The inability to control the liquid filled her with deep shame, but at the same time, deep within her, that hidden desire for submission began to awaken. Her body's reaction made her unconsciously speed up her crawl. Lena trailed behind, her magical instincts trying to resist, but the clamping of her tongue left her only able to whimper. The dripping of saliva made her eyes water, her emotions shifting from anger to a strange sense of compliance. The sensitive parts of her body grew slightly warm due to her posture. Miki guided them, her staff occasionally releasing small bursts of energy, tightening the chains slightly and reinforcing the restraints. She made them crawl around the dog kennel once. The surrounding dogs watched curiously, and a few puppies even approached to sniff them, intensifying the girls' shame. A wave of heat washed over Shiya. She had never imagined herself exposed in such a manner. Although her transformed identity was secret, this animalistic crawl made her feel unprecedentedly vulnerable. Her body reacted strongly; the tightness of her bent limbs caused a slight ache in her muscles, yet it was strangely stimulating. Each crawling motion caused her breasts to sway gently, sensitivity surging like a tide. Ziyu's crawl was more hesitant. She tried to control the dripping of saliva, but the sensitivity of her clamped tongue made her feel the tremor of her tongue with every breath. That sense of exposure churned within her. Memories of the park incident resurfaced, but this canine transformation awakened something more – she was gradually realizing her dependence on this feeling. Physically, the coolness of her saliva contrasted with the warmth of the ground, causing her [X] to involuntarily clench, as sensitive as the first time, and as fresh.

The battle was fierce and brief. Shiya's close-quarters combat kept the enemies at bay, Ziyu's purifying power shattered their defenses, and Lena's ranged attacks provided suppressive fire. Soon, the members of the evil organization began to falter, dropping their weapons and scattering. Their leader, in a last-ditch effort, attempted to detonate an energy device, but Ziyu neutralized it with a timely purification beam. A faint haze of dust hung over the plaza, and the fountain's spray continued to gush, as if mocking the brief chaos. The three magical girls stood panting, exchanging a look of victory. Shiya wiped sweat from her brow, "Looks like another success. These guys are getting bolder." Her voice held a hint of exhaustion, but more so, satisfaction. Ziyu nodded, trying to ignore the faint thrumming deep within her body—ever since the incident in the park, her senses had occasionally become sharper, especially during moments of relaxation after a fight. Lena smiled, "Yeah, but we're getting more in sync. Next time they show up, we'll finish them even faster." Just as they were preparing to withdraw, a figure appeared silently at the edge of the plaza. It was Miki, an ordinary-looking high school student, holding a wand that pulsed with an eerie light. His life had changed completely since being bound to this wand. From his initial admiration of magical girls to the gradually awakening sadistic desires, the experience in the park a few days ago had been endlessly replayed in his mind. Watching those beautiful girls reveal their vulnerability during his "training" had filled him with an unprecedented thrill. Today, he was driven by the wand once more, his target set on these magical girls. The wand trembled slightly in Miki's hand, whispering in his mind, "Remember, your mission is to train them. Transform all things with me." Miki took a deep breath and stepped into the plaza. His appearance immediately drew the attention of the three girls. Shiya frowned, "Who are you? It's dangerous here, leave quickly!" But Miki didn't respond. He raised his wand and aimed it at them. A dark crimson light shot from the wand, heading straight for the three girls. They tried to dodge, but the light was too fast, instantly engulfing them. Shiya felt a strange force field bind her body, Ziyu's purifying power seemed to fail at this moment, and Lena's magic bullets couldn't coalesce. "What is this..." Lena murmured, her voice laced with panic. Miki didn't waste time. He first transformed several nearby metal rings, turning them into flexible yet sturdy restraints. The straps, like living creatures, wrapped around the girls' wrists, binding their hands behind their backs. Shiya struggled, "Let me go! What do you want?" Her arms were pulled to their limit, her body involuntarily leaning forward, accentuating the curves beneath her pink uniform. Ziyu tried to resist with her will, but the force made her entire body go limp, "This feeling... so familiar..." Memories of the park flashed through her mind, the stimulation of being played with on the wooden horse making her cheeks flush slightly. Lena gritted her teeth, "Don't think you can trap us like this!" But her arms were firmly secured, and the hem of her yellow uniform skirt lifted slightly as she bent over. Next, Miki pointed his wand at a special item—he picked up three soft, spherical objects from the edge of the plaza. The wand's light transformed them into a connected gag device. The device was ingeniously designed, with three spheres linked by short chains, perfect for three people to use face-to-face. He walked forward, forcing their mouths open, and inserted the spheres one by one. Shiya's eyes widened, she tried to shake her head, but Miki's movements were swift and firm. The spheres filled her mouth, leaving her only able to emit muffled whimpers. Her tongue was pressed down, and saliva began to secrete uncontrollably. The feeling of being blocked made her experience this kind of training's sensitivity for the first time—the foreign object in her mouth tensed every nerve in her body, and her breathing became rapid. Ziyu was second. As the sphere entered, her eyes narrowed slightly, and a strange heat rose from within her. This wasn't the first time, but the sensitivity was still intense. The sphere pressed against her tongue, reminding her of the vibrations in the park, a stimulation that was difficult to describe, causing her to instinctively clench her legs. Her body reacted more noticeably than the others, her heart rate quickened, and her chest rose and fell unevenly. She tried to convince herself it was disgust, but deep down, a secret anticipation confused her. Lena was last. She resisted the most fiercely, but eventually, the sphere was forced into her mouth. Beneath her yellow uniform, she felt this fullness in her mouth for the first time. The frustration of her tongue being restricted brought tears to her eyes. Her body trembled sensitively, the helplessness of being gagged made her skin exceptionally sensitive, as if every breath carried an electric current. Now, the three girls stood facing each other, the chains of the gags connecting their heads, forcing them into an intimate proximity. Their hands were bound behind their backs, forcing them to bend to maintain balance, their hips slightly raised, the hems of their uniforms unable to fully conceal them in this posture. Miki watched the scene with satisfaction, a sense of control surging within him. "Now, it's time for the fountain's performance," he murmured, pointing his wand at the fountain in the center of the plaza. The wand's energy infused the fountain, and the water flow immediately changed. The gentle spray became controllable and powerful, with Miki manipulating the intensity and direction of the water jets with his mind. He first directed a thin stream of water from below to strike Shiya's [X]. Shiya's body trembled violently, the stream of water precise as a finger, stimulating her sensitive areas through the fabric of her uniform. This was her first time being trained in such a state; the coolness and pressure of the water made her muscles tense. Her psychological reaction was complex: as a close-combat magical girl, she was used to being in control, but this helplessness made her feel ashamed and a hint of inexplicable excitement. Physically, the stimulation from the water caused her [X] to gradually moisten, and her breathing through the gag became heavy and rapid. Miki adjusted the water flow and turned to Ziyu. Beneath Ziyu's blue uniform, the water jet directly impacted her private parts. She moaned softly, this time the sensation was more direct than in the park. The rhythm of the water reminded her of the previous vibrations, and the sensitivity made her gradually realize that she might enjoy this kind of training. Her mind was in turmoil: as student council president, she should be strong, but her body's reaction betrayed her. The heat from her [X] made her legs tremble slightly, and her cheeks flushed crimson. She tried to distract herself, but each impact of the water plunged her deeper into it.

Miki decided to act today. The wand glowed faintly in her hand, and she whispered, "It's time for these magical girls to taste what it's like to be controlled." She started with Shiya, deliberately creating an anomaly in a corner of the campus—an object shimmering with an eerie light, like a trap set by an evil organization. Shiya, as a magical girl, keenly sensed something was wrong. She quickly transformed, her pink uniform hugging her graceful figure, her skirt fluttering as she ran. She tracked Miki to an abandoned warehouse where she was hiding. "Come out, you evil creature!" Shiya shouted, her weapon flashing. She thought it was a regular enemy, unaware that Miki had already prepared. Miki emerged from the shadows, a smug smile playing on her lips. "Oh? Magical Girl Shiya, you've finally arrived." She deliberately revealed herself, feigning panic as she retreated, actually luring Shiya closer. Shiya, without a second thought, charged forward to launch a melee attack. Her fist, imbued with pink light, was swift and powerful. Miki's heart pounded, and she felt power surge within her. With a wave of her wand, she transformed the ropes in the warehouse into soft yet resilient restraints. Shiya's attack was skillfully dodged by Miki, and then the straps slithered like snakes, coiling around her limbs. Shiya gasped, trying to break free. "What is this? Let me go!" Her body trembled slightly as she struggled, the curves beneath her pink uniform becoming more pronounced under the strain. But the wand's power was too great, and the straps tightened rapidly, pinning her to the ground. Shiya's resolve began to waver: How could she be subdued so easily? She was usually skilled in close combat, but she hadn't expected her opponent to have such bizarre tools. Her breathing grew ragged, her chest heaving. Miki approached, her eyes gleaming with excitement. She took out another item—a white straitjacket, resembling medical equipment, but modified by her wand with a hidden control mechanism. "You need treatment, dear magical girl," Miki said softly, fitting the straitjacket onto Shiya. Shiya's body was tightly encased, her limbs immobilized. She tried to transform to enhance her power, but the straitjacket seemed to absorb her magic, leaving her feeling weak. Fear flashed through her mind: This wasn't an ordinary battle; it was a trap! Miki hoisted her up and took her to a psychiatric hospital on the outskirts of the city. She lied to the hospital staff: "This is a patient who needs urgent treatment. She has hallucinations and believes she's a magical girl. Please admit her for a two-day course of therapy." Shiya was placed in an isolation room at the hospital and, unconscious, was secured to the bed. When she woke, she found herself wearing the straitjacket, her limbs bound to the bedposts, her body unable to move freely. A soft gag was placed over her mouth, preventing her from making clear sounds, only muffled whimpers. She tried to struggle, pulling with all her might, but a mild electric shock emanated from the straitjacket, stinging her skin like a current and causing her to involuntarily curl up. Mentally, she felt humiliation and helplessness: I'm a magical girl, how could I end up like this? Her body reacted intensely; the electric shock caused her muscles to twitch slightly, her heart rate to accelerate, and fine beads of sweat to appear on her forehead. The hospital's "treatment" soon began. A device called a "treatment apparatus" was connected to the straitjacket. It was a gentle vibrator that applied stimulation to sensitive areas. Shiya's eyes widened as she felt waves of warmth emanating from her lower body. She tried to resist, but the gag prevented her from screaming, allowing only low moans to escape. The vibration gradually intensified, forcing her body to respond involuntarily. As [X] arrived, her body arched, muscles tensing, and waves of [X] washed over her like a tide, leaving her mind blank. Mentally, she felt shame yet couldn't deny the strange satisfaction: Why did she feel this way? It was like a forced release, allowing her to momentarily forget her predicament. The treatment lasted for a while, and her body went limp, her breathing rapid, her face flushed. Meanwhile, Miki wasn't done. Her next target was Ziyu. As student council president, Ziyu was in the school meeting room handling affairs when she received an anonymous message: there were signs of evil activity near the campus. She frowned and decided to investigate. After transforming, she appeared elegant and powerful in her blue uniform, confident in her purification magic. She tracked Miki to a secluded corner of the park, where Miki waited, deliberately creating a more obvious anomaly—a device emitting a dark aura. "Show yourself, I know you're here," Ziyu said calmly, the purification light in her hand shimmering. Miki again revealed a weakness, feigning escape to lure Ziyu deeper. The battle erupted, and Ziyu's purification attacks were precise and powerful, but Miki used her wand to transform the park's vines into restraining nets. Ziyu's movements were ensnared, and she gasped in surprise. "This power... it's not right!" Her body writhed in the net, her blue uniform clinging to her skin, outlining her graceful figure. Ziyu's mind began to waver: I can usually purify everything, why am I so passive this time? She vaguely sensed a strange excitement, as if the sensation of being bound reminded her of some vague desire—that feeling of liking to be disciplined, which quietly awakened within her. Miki stepped forward and fitted the straitjacket onto Ziyu's body. "You need treatment too, President," she whispered. Ziyu tried to resist, but her magic was suppressed, and she soon lost consciousness. Miki took her to the same psychiatric hospital, repeating the same lie: "Another patient, similar symptoms, two days of therapy for now." When Ziyu woke, she found herself similarly restrained on the bed, a gag sealing her mouth. Her struggles triggered electric shocks, causing her body to tremble, the current spreading along her spine, bringing a stinging sensation and a slight numbness. Mentally, she was conflicted: This restraint makes me feel... strangely comfortable? Her body's reaction was more pronounced, her lower body becoming slightly moist. She tried to distract herself, but the "treatment" device activated. The vibrator gently but persistently stimulated her, forcing [X] to gradually approach. Ziyu's whimpers came from the gag as her body writhed involuntarily, and [X] surged like waves, leaving her eyes glazed. Mentally, she began to admit that desire to be disciplined: Perhaps I really like this feeling; it brings me an unprecedented release. After [X], she lay limp on the bed, her breathing ragged, her skin flushed. Lena was the last. As the head of the literary department, she heard strange rumors in the rehearsal room: there were magical fluctuations near the school. She transformed into her yellow uniform, confident in her magical attack abilities, and headed to the abandoned teaching building. Miki had set up the final trap there, deliberately releasing an evil aura to lure Lena in. "Do you think you can escape?" Lena shouted, the magic orb in her hand radiating light. She launched an attack, yellow light shooting out like arrows. Miki dodged, exposing a weakness, and lured Lena closer. With a wave of her wand, she transformed the teaching building's curtains into flexible restraints, wrapping around Lena's limbs. Lena cried out, "Let me go! My magic..." But the straps absorbed her power, leaving her unable to resist. Her body trembled slightly as she struggled, the curves beneath her yellow uniform being pulled taut, appearing exceptionally alluring. Mentally, Lena was shocked: I always win with magic, how could I be defeated so easily? A sense of powerlessness washed over her. Miki smiled and fitted the straitjacket. "The last patient, come for your treatment too." After Lena lost consciousness, she was taken to the hospital, the lie identical: "The third one, same symptoms, two days of therapy."

Shinya, as the hostess, first spread a soft carpet in the living room. Her long hair cascaded gently over her shoulders, her well-proportioned curves subtly hinted at beneath her loose loungewear. She looked at her two friends and smiled faintly, "We all know that what happened last time… changed something for us. Today, right here, let's just relax." Her voice was soft, yet carried a tremor of anticipation. All three were adults, understanding the source of this desire, yet unwilling to delve too deeply, only wishing to find balance through this method. Ziyu nodded. She was usually the student council president, always calm and composed, but now an unusual light flickered in her blue eyes. She was gradually realizing that she seemed to enjoy that peculiar feeling of being restrained, that thrill of being unable to control herself both excited and confused her. "Mmm, I agree. Perhaps this will help us calm down." She took off her jacket, revealing her slender body, the rise and fall of her chest betraying her inner turmoil. Lena leaned back on the sofa. As the head of the literary club, she was always sensitive and passionate. Her golden hair shimmered in the sunlight, every inch of her body exuding allure. "Me too… that feeling was too intense. If I don't release it, I can barely sleep." She bit her lip lightly, a blush spreading across her face. They quickly began their preparations. Shinya retrieved several soft silk ribbons and some auxiliary tools from her room. These were props they usually used for practicing magic, now repurposed. They decided to adopt the 'Shiju-no-kote' method—a posture where all four limbs are bound together, rendering the body completely immobile, leaving them at the mercy of the [X]. Shinya demonstrated first, kneeling on the carpet, bending her arms backward, and wrapping the ribbons around her wrists and ankles, securing them in a compact position. Her body leaned forward slightly, her chest pressing against her knees, the tautness of the restraint immediately making her breath quicken. "Like this… it feels so tight, but also… stimulating." she murmured, her cheeks burning. Ziyu watched her, swallowed, and followed suit. She carefully wound the ribbons around her wrists and ankles, and after tightening them, her entire body felt as if it were encased, unable to stretch. She tried to twist a little, and the sensation of the ribbons tightening against her skin sent a shiver through her entire body, a warmth rising from her abdomen. "Ah… this is more intense than I imagined." Her mind began to churn: usually, she had to lead others, but now she willingly fell into this helpless state; this contrast made her feel both ashamed and captivated. Lena acted last, her hands trembling slightly as she bound herself. Once in position, her body swayed slightly, her sensitive areas sending waves of tingling pleasure from the friction. "Are we… really going to do this? But I can't stop." Her thoughts drifted, recalling fragments of the last 'training session,' the feeling of being controlled making her feel a little hazy even now. The three women knelt side-by-side on the carpet, their respective 'Shiju-no-kote' postures making them appear both vulnerable and alluring. They had prepared small vibrating devices beforehand, attaching them to their sensitive areas, and then activating them with remote controls. Shinya pressed her own button first. A faint buzzing sound arose, the vibration hitting her core directly, causing her to involuntarily let out a soft moan, "Mmm… so hot." Her body reacted swiftly, her skin flushing, and a sense of sinful pleasure surged through her mind—as the campus beauty, she was supposed to be a symbol of perfection, yet now she was succumbing in her own living room. Ziyu's device also activated. She closed her eyes, feeling the rhythmic stimulation wash over her. Her breathing grew rapid, her body spasming slightly, "This… is too direct." Fantasies of being 'trained' flashed through her mind, the feeling of wanting to be dominated becoming clearer and clearer; she even began to enjoy this powerlessness. Lena's reaction was even more intense. As soon as her small device turned on, her entire body tensed, and she let out soft gasps, "Ah… I can't stop." Her mental defenses crumbled, desire surging like a tide, making her forget her identity as a magical girl, leaving only primal craving. Time ticked by, their [X] gradually accumulating. Shinya's body began to sway slightly. The restraint of the ribbons prevented her from adjusting her position, leaving her to endure the increasingly intense waves. Her thoughts grew hazy, "Why… does this feel so good." Beads of sweat trickled down her forehead, mingling with the heat within her. Ziyu bit her lip, trying to suppress her sounds, but the stimulation made her whisper, "I… I'm almost…" Her body reacted intensely, muscles tensing, and psychologically, the joy of being 'trained' immersed her. Lena was already losing control, her body rocking back and forth, emitting broken murmurs, "So… so intense." Her sensitivity was the highest, the [X] coursing through her like electricity, making her vision blur. Just as they were lost in their self-imposed [X], a faint sound suddenly came from outside the door. The living room door creaked open, and a figure slipped in—it was Miki. Miki approached silently, a wand emitting a strange glow in her hand. She looked at the three bound figures, her heart racing. As the villain, her instincts drove her to act, but she also felt a sense of curiosity and excitement. "They… are actually playing like this by themselves." she murmured to herself, a sly glint in her eyes. With a slight wave of her wand, several items in the living room transformed: a silk scarf in Shinya's house became a supple restraint, a cushion on the sofa turned into a soft yet sturdy binder, and several candles melted into containers of warm wax. By the time the three noticed the anomaly, it was too late. Shinya was the first to lift her head, her eyes widening, "Who… who's there?" But her position prevented her from turning, so she could only twist her head slightly. Ziyu and Lena also became alert, but the 'Shiju-no-kote' left them immobile. The devices' vibrations continued, leaving their bodies weak and powerless. "Is… someone here?" Ziyu's voice was laced with panic. Her mind instantly shifted from [X] to vigilance, but her body's reactions prevented her from concentrating. Lena gasped, "Quick… untie me." But their wrists were bound, and they couldn't save themselves. Miki walked forward, a mysterious smile on her face. She showed no hostility, but said softly, "Don't panic, it's me, Miki. I didn't expect you to be playing such an interesting game." She crouched down, her wand lightly touching Shinya's ribbons. The ribbons instantly tightened, infused with a strange energy, making Shinya's body hypersensitive. "Ah… what are you doing?" Shinya's body jolted, the stimulation surging like a tide. Her mind was in chaos: how could someone be here? But the [X] made it impossible for her to think clearly.

"Good morning," Miki's voice was as calm as water, yet carried an undeniable authority. She placed the cloth bag on the ground, her gaze sweeping over the three of them. "Yesterday's demonstration was successful, the citizens are starting to talk. Today, we'll do some more private exercises. [X] – this will allow you to feel the essence of restraint more profoundly." Shiya narrowed her eyes, trying to sit up straight. "Are you not tired of playing yet? We are not your toys." Ziyu lowered her head, silent, but a hidden anticipation surged within her, a strange allure of control that made her fingers curl slightly. Lena looked up, her voice soft, "Please... give us some time to recover." The women in black did not respond, they simply stepped forward. The first woman approached Shiya and quickly wrapped a wide silk ribbon around her wrists, pulling her hands behind her back to secure them. The ribbon had transformed from a magic wand, its touch as smooth as satin, yet becoming incredibly strong when tightened. Shiya's shoulders were forced back, and she felt a stretching sensation in her arms, her muscles protesting slightly. The second woman dealt with Ziyu, first fastening her ankles with slender leather cuffs, then connecting a short chain, allowing her legs to only bend slightly, unable to straighten. Ziyu's blue uniform remnants were long gone, her naked body prickling in the cool air, the tremor within making her breathing slightly uneven. Lena was held by the third woman, a neckband gently fastened, the front of the band connected to a small ring that controlled the range of head movement. She tried to shake her head, "This is too tight..." but the woman had already secured her arms with cloth strips, forcing her upper body forward. The restraints gradually deepened. Miki personally supervised, waving her wand, transforming old blankets from the corner of the dungeon into three low platforms, each covered with soft padding, but surrounded by adjustable supports. Shiya was lifted onto the first platform, and the women in black spread her legs apart, knees bent, and secured them with flexible vines to the edges of the platform. A wide strap was placed across her waist, tightened to make her abdomen slightly concave, but not hindering basic breathing. Her hands remained behind her back, and her head was secured by a soft head-cuff frame, from which thin straps extended to connect to the platform, forcing her to look straight ahead. Shiya's chest rose and fell rapidly. "Let me go, you will pay the price." Miki smiled. "This is just the beginning. Take a deep breath, feel the flow of air." Ziyu's platform was adjacent. She was placed in a kneeling position, her legs together and secured, her knees pressing into the padding, unable to move. Her arms were pulled forward and bound to a horizontal bar at the front of the platform with silk loops, forcing her upper body to droop. The neckband was connected to a stretchable thin chain, the end of which was fixed beneath the platform, allowing her head to be only slightly raised. A woman in black adjusted the tightness of the belt, and Ziyu felt a slight pressure on her chest, the tightness of being restricted making her cheeks flush. She whispered to Lena, "Don't be afraid, we'll get through this together." Lena nodded, but her placement was more complex: on the platform, she was placed in a supine position, her legs raised high and secured to the supports with leather straps, her knees bent at a ninety-degree angle. Her arms were stretched overhead, her wrists fastened above the platform. Her head rested on a semi-circular pillow, and the neckband was tightened to lift her chin slightly, preventing her from turning her head. Lena's eyes welled up. "I feel... so exposed." Once fully restrained, Miki took out several small devices from the cloth bag: transparent film covers, soft nose clips, and several adjustable breathing tubes. These had been transformed from magic wands, seemingly simple, yet capable of precisely controlling the intake and outflow of air. "Today's goal is to let you experience the rhythm of breathing," Miki explained. "Through these, we will alternately supply oxygen and restrict it, observing your reactions. Remember, this is not punishment, but reinforcement." The women in black began to operate. Starting with Shiya, one woman gently placed a film cover over her mouth and nose, the edges fitting snugly against her skin, connected to a thin tube that could regulate airflow through a valve. Shiya's nostrils twitched, and she took a deep breath. "What is this..." Before she could finish, the woman turned the valve, reducing the airflow by half. Shiya's chest immediately expanded, her lungs craving more air. She tried to accelerate her breathing, but found that the cover restricted her rhythm, and the head frame prevented her from breaking free. Ziyu's device was slightly different: a nose clip gently pinched her nostrils, leaving only her mouth free, but a ring strap went around her chin, connecting to the neckband, which could press on her mouth opening when tightened. The woman first let her breathe normally for a few breaths, then slowly tightened the ring strap. Ziyu's lips parted slightly, air entering through the narrow passage of her mouth. Her body instinctively leaned forward, but her fixed arms prevented it. Lena's was a full-face mask, covering her mouth and nose, with a micro-valve inside that could simulate different breathing resistances. Her supine position intensified the sensation. On her first deep breath, everything was normal; but when the valve closed for half a second, her face instantly turned red, her eyes widened. "Air... too little." Miki nodded. "Very good, now we begin the cycle. Fifteen minutes per person per round, we will adjust in turns to ensure your bodies adapt." The first round began with Shiya. The woman in black stood by the platform, holding the control tube, briefly interrupting the airflow every five seconds. Shiya's breathing was initially regular, but when the interruption extended to ten seconds, her body began to tremble, her chest expanding to its limit, beads of sweat trickling down her forehead. Her mind was in a struggle: as a close-combat expert, she was used to controlling the rhythm, and this passivity now ignited a powerless rage within her. When the air returned, she inhaled deeply, her lungs relieved, her body relaxing, a warmth rising from her abdomen. Ziyu watched from the side, her heartbeat accelerating in sync, and her device was activated. As the ring strap tightened, her chin was pressed down, her mouth could only take small breaths, and the suffocating feeling made her knee muscles tense. As student council president, she tried to maintain her composure with willpower, but the second round of interruption made her let out a low hum, and heat began to accumulate within her body, that allure of restraint making her eyes hazy. Lena's turn was interwoven. The mask's valve had a faster rhythm, three seconds of interruption followed by recovery. Her body arched in the supine position, the leg supports tightening to the point of making a slight noise. As the head of the literary club, she began to weave images in her mind: breathing like a tide, surging in and receding. But when the interruption reached fifteen seconds, her vision blurred, and tears welled up in the corners of her eyes. Miki approached, observing, "Lena, your reactions are very poetic. Continue." The woman in black adjusted the device, making the airflow during the recovery period more abundant. As Lena gasped for air, her whole body felt relieved, her sensitive parts throbbing. She murmured softly, "This... is like a ship in a storm." The cycle gradually deepened [X], and the devices of the three were operated simultaneously. Shiya's film cover airflow was reduced to the minimum, her body gasping for air convulsively, her face contorted under the head frame, sweat soaking the platform. The intermittent rhythm of the air made her [X] contract, memories of last night's plaza superimposed, waves of heat washing over her. Ziyu's ring strap repeatedly tightened and loosened, her kneeling posture making her unstable, her mouth dry, her breathing turning into rapid gasps. The hidden pleasure made her feel a trace of [X] in the suffocation, the heat in her abdomen growing, she tried to say to Shiya, "Hold on... I'm okay." But her voice was muffled by the device, only a vague hum remaining. Lena's mask valve simulated waves: long interruptions followed by short recoveries, her body swaying in the supports, her leg muscles twitching, tears sliding down the pillow. Her psychological defenses loosened, the imagined poetry turning into fragmented murmurs: "Air... like a lover's embrace." Fifteen minutes later, the first round ended. The women in black partially released the restraints, allowing the three to recover. They panted and exchanged glances. Shiya spoke first, "This is too torturous, we can't just go on like this." Ziyu nodded, her voice hoarse, "But... the body is adapting." Lena wiped her cheeks, "I feel like I'm floating." Miki surveyed them with satisfaction, "Rest for two minutes, then continue. The second round will be intensified, combined with physical stimulation." The women in black took out auxiliary tools: soft vibrating pads and light brushes, which were placed under the platforms and could be activated by changes in airflow. The second round began. The pad under Shiya's platform vibrated lightly, synchronized with the breathing interruption. When the airflow slowed, the vibration intensified, and her body responded instinctively, her chest heaving with tremors. Her lips under the film cover turned pale, and as she gasped for air to recover, a wave of heat rushed to her [X], making her let out a low moan. Ziyu's device had an added mouth brush, lightly brushing her tongue. As the ring strap tightened, the brushing intensified. Her kneeling posture made her hips lift slightly, the suffocation of her breathing mingling with the stimulation, and the allure made her whisper inwardly: Why does this feel so intense? Under Lena's supports, the brush moved externally between her legs, and when the valve interrupted, the brushing accelerated. Her supine body arched, her breathing turning into sobs, "Too... intense." Miki recorded from the side, "Ziyu, your pulse is rising. Very good." The process continued. In the third round, all three reached their peak simultaneously. The airflow interruption was extended to twenty seconds, and during the recovery period, the vibrating pads turned into pulses. Shiya was the first to reach the edge, her film cover fogging up, her body tensing, and as waves of heat erupted, she let out a muffled cry, her entire body feeling like it was coursing with electricity. Ziyu followed closely, the pressure of the ring strap allowing her to release in the suffocation, her knees trembling, the hidden pleasure making her blush to the roots of her ears. Lena was last, her gasps under the mask turning into low cries, the accumulation of stimulation making her convulse in the supports, her vision turning white. The women in black controlled precisely, avoiding excess, ensuring recovery after each round. As noon approached, Miki ordered a brief interruption. The three were partially released from their restraints, allowed to drink water and wipe their bodies. Shiya rubbed her shoulders, "They are testing our limits." Ziyu lowered her head, "But I... am a little lost." Lena chuckled softly, "Perhaps, this is their trick." The afternoon continued, and the fourth round introduced a change: the devices were linked together, Shiya's breathing rhythm affecting Ziyu, and Ziyu's affecting Lena. As Shiya inhaled deeply, Ziyu's ring strap loosened; as Ziyu exhaled, Lena's valve closed. This linkage made their bodies tremble in sync. Shiya felt her partner's rhythm, "Ziyu, slower..." Ziyu responded, "I can't control it." Lena murmured, "We are connected as one."
