The President's Secretary's Secret

The first thing seen is black. Mirror-like black, reflecting the warm yellow light. It's a person's back, covered in a layer of material clinging to the skin, smooth, reflective, like a second skin. The black flows down the hollow of the spine, constricting at the waist, then spreading across the seat of the chair. The chair is custom-made, with a metal frame, multiple buckles, and supports. The black material is a one-piece suit, enveloping from the neck down to the ankles. Wrists, elbows, thighs, and ankles are fitted with silver-gray metal rings, magnetically attached, currently clamped firmly onto corresponding metal buckles on the chair. The rings are tight, indenting the flesh beneath the black covering, the skin at the edges turning slightly pale. The bound person's head is tilted back, the neck forming a taut arc. The black latex has a hidden seam at the neck, and this seam is visibly tightening, as if being squeezed by an invisible hand. A suppressed, hoarse gasp emanates from the throat, and the black on the chest heaves violently. It's Lin Ruoyi. Su Wantang's fingernails dig into her palm. Lin, the secretary who was so decisive and impeccably dressed during the day, who could silence a department head with a single glance, is now pinned to this chair. Her long hair is disheveled, falling over her shoulders, a few strands clinging to her sweaty neck and cheeks. A gag is in her mouth, a dark red ball filling her oral cavity, its black straps tied securely at the back of her head. A glistening trail of saliva stretches from the corners of her mouth, dripping down onto the black latex just below her collarbone, forming a small, reflective wet patch. Her eyes are half-open, pupils dilated, her gaze unfocused, lost somewhere in the air. Her eyelashes are matted with sweat. With every breath, the two mounds tightly encased in black latex rise and fall dramatically, the peaks clearly visible beneath the smooth surface. A humming sound comes from her inner thighs. A thick, short cylindrical object is fixed there, pressed against the latex, vibrating at a high frequency. The smooth black surface is rippled by the vibration, like water. The tremor travels through her thigh muscles, causing her entire lower body to tremble uncontrollably. There's something else deeper within. Between her legs, at the crotch of the black latex suit, the outline of a metal structure is faintly visible—the shell of a chastity device. At this moment, something is clearly working inside the shell, because Lin Ruoyi's waist is arching in small, spasmodic movements to a certain rhythm. With each arch, a muffled groan, completely obstructed by the gag, escapes her throat. Su Wantang's legs begin to weaken. She has to brace herself against the doorframe to stay upright. Her gaze is drawn as if by a magnet, fixed on that sliver of light. She watches the latex on Lin Ruoyi's neck tighten again, watches her head forced back further, her Adam's apple bobbing, her gasps turning into broken sobs. She watches her waist arch faster and faster, the vibrator on her inner thighs emitting a deeper hum. She watches her toes curl within the black latex, her insteps taut, her heels pressed hard against the chair legs. Then Lin Ruoyi's entire body arches upwards sharply. Her spine detaches from the chair back, only the metal buckles at her wrists, elbows, thighs, and ankles holding her in place. She is like a drawn bow, her neck arched to its limit, her chest lifted high, her abdomen tightened, her root trembling violently. The whimpers escaping the gag suddenly escalate, becoming continuous, death-like moans, only to be muffled again by the ball, leaving only a leaky, "hissing" sound from the depths of her throat. She holds that pose, her entire body trembling with tension, for several seconds. Sweat rolls down her forehead, temples, and neck in large drops, tracing glistening wet streaks on the black latex. The vibrator on her inner thighs continues to work frantically, and the chastity device's internal mechanism has clearly reached some peak, as her lower abdomen is even convulsing subtly and continuously. Finally, the breath escapes. She collapses back heavily onto the chair, her body going limp, only her chest heaving. Her head lolls to one side, her eyes completely closed, only her eyelashes still trembling. Saliva continuously flows from the edges of the gag, mixing with sweat, soaking the black latex on her chest until it gleams wetly. The humming stops. Silence seeps back in. Only Lin Ruoyi's heavy, hoarse breaths, one after another, drift in the warm yellow light. Su Wantang realizes she's also panting. She doesn't know when she held her breath, and now her lungs burn. She releases her hand from her palm, the nail marks deeply embedded in her flesh. Her legs are too weak to stand, so she slides down the doorframe, crouching in the shadow of the hallway. Her heart pounds as if it will explode. A strange, burning ache surges from the depths of her lower abdomen, and the area between her legs feels sticky and wet. She looks down and sees a dark wet stain spreading on the fabric of her beige skirt, on the inside of her thighs. Her hands are shaking. Uncontrollably, her fingers lift the hem of her skirt and slip under the edge of her underwear. It's a mess inside, the fabric clinging to her skin. The moment her fingertips touch, they sink into a slick, hot, soft flesh. She bites her lower lip, stifling a sound in her throat, her fingers sliding into the wet crevice, finding the swollen, hardened nub. The slightest touch sends a current of pleasure from her tailbone straight to the crown of her head. She curls up in the shadow by the door, her back against the cold wall, her eyes still fixed on the sliver of light from the door crack. Inside, Lin Ruoyi lies limp on the chair, her body occasionally twitching like a beached fish. Outside, her fingers move rapidly and forcefully between her own legs, mimicking the vibration frequency she just witnessed, mimicking the rhythm of collapse after being pushed to the absolute limit of restraint. The bottom drawer of the wardrobe, usually hidden beneath a pile of scarves and old sweaters. She crouched down, moved the items aside, revealing the drawer itself. Wooden, with chipped paint along the edges. She gripped the handle, paused for a few seconds, then pulled it open. There were no scarves or sweaters inside. At the top lay a cardboard box, pink, with the logo of a certain adult novelty store printed on it, its edges worn smooth and white. Beside the box were several small bottles of lubricant, some half-used, others still sealed. Beneath them, pressed flat, were a few notebooks—not for work, their covers plain, unadorned. Su Wantang picked up the pink box first. Opening it, she found a bullet vibrator. A plastic casing, pale pink, its surface a little too smooth, a little too cheap. The main body was egg-shaped, connected to a thin wire, at the end of which was a tiny remote, also pink, with a few buttons. Battery-powered, its vibrations would weaken with use, sometimes stuttering. She took the bullet vibrator out, holding it in her hand. The plastic shell was cool, weightless. Her finger pressed the switch on the remote, and the bullet vibrator pulsed weakly in her palm, its hum a little too loud, like a cheap electric toothbrush. She turned it off. Her gaze drifted to the back of the drawer. There, wrapped in velvet cloth, was a long, cylindrical object. She reached for it, unwrapping the velvet. It was a realistic dildo. Silicone, flesh-toned, of medium size. The craftsmanship wasn't exquisite; the texture of the surface was somewhat blurred, and it had a round base. It felt yielding to the touch, but she could feel the firm support material inside. She looked at the objects in her hands. A plastic bullet vibrator. A silicone dildo. Rudimentary lubricant. This was her entire secret collection. Bought online in secret during college, her heart pounding when it arrived, her hands trembling as she unboxed it. She'd added a few things over the years, but it had always remained these—cheap, anonymous things, for her private use. That image flashed in her mind again. A midnight black catsuit, high-gloss, like a second skin. Magnetic metal cuffs on her wrists, elbows, thighs, and ankles, silver-grey, with a crisp *click* when they fastened. A hidden collar at her neck, capable of being tightened remotely. A chastity device, metal casing, with a remotely controlled penis inside. A vibrator secured to her inner thigh, its hum deep and powerful. Professional. Exquisite. Expensive. Like some kind of precision instrument, designed solely for control and pleasure. She looked down at the pink plastic bullet vibrator in her hand. Inferiority. That sharp sting of envy mixed with shame, felt when seeing someone possess something she yearned for but dared not touch. She wanted that. Not to be in Lin Ruoyi's position, but to feel that—to be encased, bound, controlled by such intricate equipment. To have her joints locked by metal rings, her senses dulled by the catsuit, her breath and pleasure dictated by a remote. To be the one sprawled on the chair, sweat darkening the black latex, collapsing in a heap of orgasmic release. The thought was terrifyingly clear. She placed the dildo back into its velvet wrap, the bullet vibrator into its box, and the box back into the drawer. Her movements were swift, as if fleeing from something. But the moment the drawer clicked shut, she stopped. Her hand rested on the drawer handle, her fingertips white. Close your eyes, and the fantasy begins. The first sensation is the latex. It envelops you from the neck down, clinging to every inch of skin, smooth, cool, like a second skin. Pressure on your wrists, elbows, thighs, ankles, the click of magnetic metal cuffs locking into place, one by one. Your joints are secured, allowing movement, but only within a very limited range. The slightest shift presses the metal edge against your flesh. Then, your neck. The latex has a hidden seam there. Now, that seam begins to tighten, slowly, relentlessly, digging into your throat, circling your Adam's apple. Breathing becomes difficult, a hoarse rasp escaping your throat with each inhale, your chest forced to rise, your breasts pushed high beneath the latex. There's something in your mouth. A ball gag filling your oral cavity, the straps cinched tight behind your head. Saliva flows uncontrollably, spilling from the corners of your mouth, down your chin. Your lower body. The cold, heavy metal shell of a chastity device presses against your inner thighs. Inside, there's more than just a simple rod; it's a complex mechanism, capable of extending, thrusting, vibrating, and delivering electric shocks. It's active now, working at a rhythm you can't control, churning deep within you. Pleasure builds, urgent and intense, your lower abdomen tightening, your inner thighs spasming. A vibrator is also pressed against your inner thighs, beneath the latex. Its high-frequency vibrations send an uncontrollable tremor through your entire lower body. You can't see who's operating it, but you feel the presence of that hand—perhaps holding a remote, perhaps watching from nearby. That hand controls the tightness of the neck collar, the patterns within the chastity device, the frequency of the vibrator. Your every reaction, every gasp, every tremor, every near-collapse into orgasm, is under its command. The pleasure in this fantasy is a hundred times more potent than the friction of your own fingers in reality. Su Wantang's fingers slide rapidly between her legs, mimicking the rhythm of the imagined vibrator, the sensation of being filled and stimulated. Her other hand unconsciously clutches the bedsheet, the fabric bunching into a fist. She turns onto her side, curling her legs, her knees pressing into her abdomen, a position that allows her fingers to reach deeper, to stimulate that most sensitive spot. Her breathing grows ragged, choked moans escaping her throat, short and broken. Sweat beads on her forehead, trickling into her hairline, down her neck. The back of her knit shirt is soaked, clinging to her skin. The fantasy continues. She sees herself arching her back like Lin Ruoyi, her neck thrown back to its limit, her chest thrust high. The latex gleams under the light, sweat leaving shimmering trails. The metal cuffs bite into her flesh, her wrists and ankles chafing red from her struggles. The ball gag fills her mouth, muffling her moans into guttural, airy gasps from deep in her throat. At the moment of climax, fantasy and reality merge. A silent white light explodes in her mind, surging from the base of her spine, engulfing every nerve. Her body snaps rigid, her toes curling, her calf muscles trembling, her abdomen contracting violently, her inner thighs clamping down on her fingers in a spasm. A torrent of heat rushes from her depths, soaking her underwear, her fingers, even seeping through the fabric of her skirt. Her mouth hangs open, gasping silently. The aftershocks of orgasm wash over her body in waves, bringing a fine, scalp-tingling itch. Her vision darkens, her ears ring. After a long time, her breathing slowly calms. She withdraws her fingers, fingertips slick, glistening in the lamplight. Her body lies limp on the bed, boneless, too weak to even move a finger. Sweat plasters her hair to her cheeks and neck, her wet knit shirt clinging uncomfortably. But her mind is exceptionally clear. The orgasm she just experienced was more intense than any before. Not because of technique, not because of toys, but because of the fantasy—the fantasy of being encased in latex, bound by metal, controlled by a remote, utterly collapsing under the command of a stranger. Lin Ruoyi knelt on the ground. Not a normal kneeling, but on all fours, elbows and knees pressed against the floor. She wasn't wearing a black catsuit, but something else—thick, matte black leather, encasing her arms from forearm to upper arm, her thighs from knee to groin. The leather harnesses were tightened with silver metal buckles, leaving deep indentations at the joints. Short chains connected the harnesses, forcing her limbs into a bent position, unable to fully straighten. Around her neck was a wide leather collar, black, edged with a band of fine silver studs. A metal chain was attached to the front of the collar, its other end held in Lu Chenyuan's hand. He sat on a single sofa not far away, his suit jacket draped over the armrest, shirt sleeves rolled up to his forearms. He held the chain in one hand, and a black remote control in the other. Lin Ruoyi wore a dog mask on her head. Also made of black leather, it completely encased her head, connecting to the collar only at the jaw and neck. The eye areas of the mask were two opaque black lenses, the nose section was a raised, sculpted shape, and the mouth was a protruding cylinder that fit into her oral cavity. The end had holes, and through them, suppressed, wet whimpers could be faintly heard. Something was also attached to her back. A leather strap extended from the back of the collar, running down her spine, forking at the waist. Her hips were slightly arched. Lu Chenyuan tugged lightly on the chain. Lin Ruoyi's body shifted forward a step. Her elbows and knees moved across the floor, the leather emitting a dull friction sound. The movement was not fluid, marked by the stiffness and awkwardness of restraint, but steady, step by step, crawling towards Lu Chenyuan. Reaching the sofa, Lu Chenyuan nudged her shoulder with his toe. She stopped, her head lowering until her forehead almost touched the ground. Her back arched more severely, her hips rising higher. The posture exuded complete submission. Lu Chenyuan's finger tapped the remote control. Lin Ruoyi's body jolted violently. Not a large tremor, but a spasm erupting from within, forcefully suppressed. The muscles in her arms, supporting her on the ground, tensed instantly, the lines clearly defined beneath the leather harness. A whimper, muffled by the mask, escaped her throat—short, pained, yet carrying an indescribable tremor. Her waist began to sway slightly, uncontrollably, her hips gently rocking with the movement. Su Wantang held her breath. She saw, near the inner thighs of Lin Ruoyi's leather harness, faint damp marks seeping out, spreading a small dark patch on the matte black. Sweat, or something else, it was impossible to tell. But the swaying, the whimpering, the state of her entire body tensing and trembling—she believed it was an orgasm, or being forcibly pushed to the brink of one. Lu Chenyuan released the button on the remote. Lin Ruoyi slumped, her arms trembling, barely able to support her body. Her head hung lower, her breaths escaping through the mask's breathing holes, heavy, wet, and choked with sobs. Lu Chenyuan reached out and touched her head. His fingers brushed the top of the leather mask, a light touch, as if stroking a real pet. Then he tugged the chain again. Lin Ruoyi raised her head. Lu Chenyuan pointed to another corner of the room. A metal dog bowl sat there, filled with water. She crawled over. The movement was slower than before, more strenuous, her leg roots still trembling subtly. Reaching the bowl, she lowered her head, trying to reach the water with her mouth. The cylinder at the mouth of the mask hindered swallowing, and water spilled from the corners of her mouth, dripping onto the floor, onto the collar and the leather on her chest. Su Wantang watched the scene. On all fours, leather harness, dog mask, pulled by a chain, drinking with her mouth. Every part of Lin Ruoyi that belonged to a "person" was encased, twisted, redefined into another form. The efficient, meticulously made-up Secretary Lin from daytime was now merely a bitch, leashed, controlled by a remote, crawling on the verge of climax. Lin Ruoyi struggled to get up, crawling on her knees to his legs. Lu Chenyuan reached out, grasped one of her elbows, and gently pulled. Lin Ruoyi obediently raised her arm. Lu Chenyuan pulled her arm towards the armrest of the sofa. Just as her elbow neared a metallic decorative point on the side of the armrest, the fine seam on the latex at her elbow suddenly emitted a faint blue light, followed by a soft "click." The latex around her elbow seemed to come alive, and something inside instantly adhered to the metal point on the sofa armrest. Lin Ruoyi's arm was fixed, her elbow bent, and her forearm suspended in the air. Lu Chenyuan then lifted her other arm, repeating the process, securing it to the other side of the sofa armrest. Now Lin Ruoyi knelt in front of the sofa, her arms magnetically cuffed to her sides, forming a slightly open posture. Next were her legs. Lu Chenyuan nudged the outside of her knee with his toe. Lin Ruoyi obediently spread her legs. Lu Chenyuan leaned down, grasped her thigh, and pushed the outside of her thigh towards the metal edging at the base of the sofa. The same "click" sounded as the magnetic cuffs at her thighs activated, securing her legs to the sofa base. Now she was completely immobilized. Kneeling, her hands cuffed to her sides, her legs spread and secured, her body leaning slightly forward. The two mounds of her breasts, rising and falling violently beneath the latex, were fully exposed to Lu Chenyuan's gaze. The wet chastity device at her crotch was completely uncovered. Lu Chenyuan leaned back onto the sofa and picked up the remote control. This time, he pressed and held a button. The slightly darker seam of latex around Lin Ruoyi's neck began to slowly tighten. Visibly, the black latex dug into her skin. Her throat was compressed, and her breaths immediately became difficult and hoarse. Her head was forced back, her jawline taut, her Adam's apple bobbing, her face rapidly flushing red. Her eyes widened, reflecting the warm yellow light of the ceiling and... the blurry shadow of the ventilation grate? Su Wantang held her breath inside the duct. She watched Lin Ruoyi fixed in that shameful position, watched her neck tighten in the collar, watched the vibrator at her nipples work furiously, watched the chastity device continuously grind and thrust between her legs, watched her entire body soaked in sweat, glistening under the light. Then she saw Lin Ruoyi climax. It wasn't a sudden explosion, but a collapse after reaching the limit. Her body trembled violently as if electrocuted, her fixed limbs struggling in vain, the magnetic cuffs emitting soft "clacking" sounds. A death-like moan, sharp and broken, was squeezed from her throat, choked by the collar. Her abdomen tightened to its limit, and a large amount of crystal-clear fluid gushed from beneath the chastity device's guard, splattering onto the carpet and her own thighs and stockings. The trembling continued for a long time. Finally, she went limp, only her fixed limbs maintaining their position. Her body hung in the air like a broken puppet. Her head drooped, her long hair disheveled, sweat dripping from her chin, forming dark circles on the carpet. Lu Chenyuan released the button on the remote. The collar around her neck slowly loosened. Lin Ruoyi gasped for air, then began to cough violently, her shoulders convulsing, tears streaming down her face mixed with sweat. Lu Chenyuan reached out and touched her head. The movement was gentle, like soothing a pet. Then he pressed another button on the remote, and the magnetic cuffs clicked open. Lin Ruoyi's arms and legs fell limply, and she collapsed onto the carpet, curling into a ball, her body still trembling slightly. Su Wantang, inside the duct, dug her fingers into the edge of the grate. She didn't know when she had slipped her fingers inside her skirt. By the time she realized it, her underwear was soaked, and her fingertips were buried in the hot, muddy flesh, mimicking the thrusting rhythm she had just witnessed, moving in and out rapidly. The scene in the room below was seared into her mind like a brand. Black latex, magnetic cuffs, her neck tilted back as the collar tightened, the hum of the nipple vibrator, the mechanical sound of the chastity device thrusting, the spraying bodily fluids, the full-body spasms of orgasm. She imagined it was herself. Her arm was secured, elbow bent, forearm dangling. Lu Chenyuan then lifted her other arm, repeating the process, securing it to the other side of the sofa armrest. Lin Ruoyi was now kneeling before the sofa, her arms held to her sides by magnetic restraints, forming a slightly open posture. Next were her legs. Lu Chenyuan nudged the outside of her knee with his toe. Lin Ruoyi obediently spread her legs. Lu Chenyuan leaned down, gripping her thighs, and pushed the outer sides of her thighs towards the metal trim of the sofa base. The same "click," and the magnetic restraints on her thighs engaged, securing them to the sofa base. Now she was completely immobilized. Kneeling, hands fixed to her sides, legs spread and secured, her body leaning slightly forward, the two mounds of breasts beneath the latex suit heaving violently were fully exposed to Lu Chenyuan's gaze. The wetness of the chastity cage at her crotch was utterly unconcealed. Lu Chenyuan leaned back onto the sofa again and picked up the remote. This time, he pressed and held a button. The slightly darker seam of the latex suit around Lin Ruoyi's neck began to slowly tighten. Visibly, the black latex band dug into her skin. Her throat was compressed, and her gasps for air immediately became labored and hoarse. Her head was forced back, her jawline taut, her Adam's apple bobbed, and her face rapidly flushed red. Her eyes widened, pupils reflecting the warm yellow light of the ceiling, and... the blurry shadow of a ventilation grate? Su Wantang held her breath inside the duct. She watched Lin Ruoyi pinned in that humiliating pose, watched her neck tighten in the collar, watched the vibrator at her nipples work furiously, watched the continuous grinding and thrusting inside the chastity cage at her crotch, watched her entire body soaked in sweat, glistening wetly under the light. Then she saw Lin Ruoyi climax. It wasn't a sudden burst, but a collapse after reaching the limit. Her body trembled violently as if electrocuted, her fixed limbs struggling in vain, the magnetic restraints emitting faint "clack" sounds. A death-like moan, sharp and broken, was squeezed from her throat, choked by the collar. Her abdomen tightened to its extreme, and a large gush of clear liquid surged from beneath the chastity cage's plate, splattering onto the carpet, and onto her own thighs and stockings. The trembling continued for a long time. Finally, she went limp, only her secured limbs maintaining the pose, her body hanging in mid-air like a broken puppet. Her head drooped, her long hair disheveled, sweat dripping from her chin, forming dark circles on the carpet. Lu Chenyuan released the button on the remote. The collar around her neck slowly loosened. Lin Ruoyi gasped for air, then began to cough violently, her shoulders convulsing, tears mixing with sweat streaming down her face. Lu Chenyuan reached out and touched her head. The movement was gentle, like soothing a pet. Then he pressed another button on the remote, and the magnetic restraints released with a "click." Lin Ruoyi's arms and legs dropped limply, and she collapsed onto the carpet, curling up, her body still trembling slightly. Inside the duct, Su Wantang's fingers dug into the edge of the grate. She didn't know when she had slipped her fingers inside her skirt. By the time she realized it, her underwear was already soaked, her fingertips buried in the slick, hot flesh, mimicking the thrusting frequency she had just witnessed, moving in and out rapidly. The scene in the room below was seared into her mind like a branding iron. The black latex, the magnetic restraints, her neck arched as the collar tightened, the hum of the nipple vibrator, the mechanical sound of the chastity cage thrusting, the splattering bodily fluids, the full-body spasms of orgasm. She fantasized it was herself. She fantasized herself wearing that latex suit, kneeling before the sofa, her wrists and legs secured by magnetic restraints. She fantasized Lu Chenyuan pressing the remote, the bullet vibrator at her nipples beginning to buzz, the metal rod in the chastity cage thrusting deep inside her. She fantasized the collar slowly tightening, the sensation of suffocation mixing with pleasure rushing to her head. She fantasized herself, in such complete bondage and control, collapsing, screaming, climaxing. Su Wantang bit her lower lip, gripping the edges of the maintenance hatch with both hands. She exerted force, hoisting herself up. Her elbows pressed against the rough inner wall of the pipe, a chill seeping through her shirt sleeves. She twisted her waist, pulling her legs in, then turned and slid the panel back into place, leaving it unlatched. The pipe was pitch black. Only a faint light from a distant grille cut blurry grey lines across the dust-covered walls. The air was stagnant, hot, carrying the metallic tang of rust and aged dust. She switched on her phone's flashlight, dimming it to its lowest setting. The beam illuminated a small section of wavy metal ahead. She began to crawl. Her knees and elbows pressed against the metal, emitting dull thuds. Slower and more cautious than last time, she paused with every movement, listening for any sounds below. Crawling past the right-angle bend, she saw the dense grille ahead. Warm yellow light filtered up from below. She crawled to the edge of the grille and lay down, pressing her face close. Her vision was cut into countless small squares, but piecing them together, she could make out the room below – a person lying on a platform. Lin Ruoyi, she lay supine in the center of the platform, her body completely stretched out. She was wearing that midnight black, high-gloss latex bodysuit, like a second skin, but her posture was entirely different from last time. Her legs were spread apart, knees bent, soles of her feet pressed against the platform surface, thighs splayed outwards, forming a standard M-shape. Her inner thighs were thus fully exposed. The black latex connected to the matte metal chastity belt at her crotch, the belt buckled at her waist, its curved guard pressed tightly against the lower part of her abdomen. Her hands were cuffed behind her back, the outline of metal rings visible beneath the latex at her wrists, clearly restrained. A black leather blindfold covered her eyes, edged with fine rivets, completely obscuring the upper half of her face. Only the lower half was visible – her lips slightly parted, her lipstick a deep red, appearing moist under the warm yellow light. Lu Chenyuan stood at the edge of the platform, holding the black remote control. He looked down at Lin Ruoyi on the platform, his expression unreadable, the lenses of his gold-rimmed glasses reflecting the light. He pressed a button on the remote. Lin Ruoyi's body trembled slightly. Beneath the latex on her chest, the two silver-grey metal protrusions began to vibrate, emitting a low hum. The breasts under the latex rippled subtly, and her nipples quickly became engorged, forming two distinct points. Lu Chenyuan's finger slid across the remote. The humming shifted to a pulsing mode, coming in waves. Lin Ruoyi's breathing quickened in rhythm with the rhythm, her chest rising and falling more rapidly. Her lips parted, and a short moan escaped: "Mmm..." Then Lu Chenyuan pressed another button. Lin Ruoyi's waist arched sharply upwards, lifting off the platform surface. It wasn't a large movement, but a distinct, upward arching of her lower abdomen. Simultaneously, beneath her lower abdomen, above the guard of the chastity belt, her flat abdominal skin showed a clear, rhythmic bulge. Once, then again. As if something deep within her body was thrusting upwards, pressing against her inner walls. The bulge appeared and disappeared with the rhythm of the thrusting, then reappeared. The frequency was steady, the force even. The metal rod within the chastity belt was working. Thrusting. Pushed in from below, reaching deep, creating a shape against her lower abdomen. "Ah... Haa..." Lin Ruoyi's moans became continuous, rising with each thrust. Her head moved unconsciously from side to side on the platform, her long black hair fanning out, sticking to her sweaty neck and the platform surface. Her hands, cuffed behind her back, struggled in vain, the metal rings at her wrists rubbing together, emitting faint "clinking" sounds. Her M-shaped legs began to tremble. The black latex on her inner thighs became damp with sweat, glistening. At her crotch, at the edge of the chastity belt's guard, a clear liquid began to seep out, not slowly, but squeezed out with each deep thrust, splashing onto the smooth black marble surface of the platform, leaving behind small, dark circles. Su Wantang's throat tightened, rendering her speechless. "How long have you been watching?" he asked. "A... over a month." Lu Chenyuan nodded, as if this answer was within his expectations. He leaned forward, elbows on his knees, hands clasped. "What did you see?" Su Wantang parted her lips. Countless images flashed through her mind: the black latex suit, the magnetic restraints, her neck tightening with the collar, the rising and falling swell of her lower abdomen, the splashing fluids, the breakdown of tears and pleas. But these images clogged her throat, turning into a hot, shameful lump. "I saw..." she took a breath, "I saw Secretary Lin... being..." "Trained," Lu Chenyuan finished for her, his tone as casual as if he were discussing work assignments. "Yes," Su Wantang closed her eyes. "Did you enjoy it?" The question was like a knife, directly slicing through all her pretense. Su Wantang's eyes snapped open, and she looked at Lu Chenyuan. His expression was still impassive, his eyes behind his glasses unfathomably deep, awaiting her answer. Did she enjoy it? Those nights, hiding behind the door crack, behind the potted plants, inside the ventilation ducts. Her heart racing, palms sweating, her thighs damp, climaxing alone in the darkness. The crude toys in her drawer, the handwritten fantasy notebook. Inferiority, longing, fantasizing about being the person in those scenes. "...Yes," her voice was so faint it was barely audible. Lu Chenyuan leaned back against the sofa. "Why?" Why? Su Wantang's mind was a chaotic mess. Because of the thrill? Because of the beauty? Because of that feeling of being completely controlled, utterly powerless to resist? Because it was the deepest, most forbidden desire hidden in her heart? "Because..." she organized her thoughts, each word burning her tongue, "Because... she looked... completely controlled. Unable to move, unable to escape, even her breathing and... her orgasms, were decided by someone else." Lu Chenyuan listened quietly. "What else?" "And..." Su Wantang's gaze drifted unconsciously to the black marble platform in the center of the room, its surface still bearing the sheen of un-wiped water stains, "...that equipment. The latex suit, the metal restraints, the remote control... it's very... precise. As if designed specifically for that." "Not for 'that'," Lu Chenyuan corrected her. "It's for 'control'." He reached out and took the black remote control from a low table drawer beside the sofa. Its surface was matte, with no protruding buttons, only a small red indicator light, currently extinguished. Su Wantang's fingers paused on the cool metal guard. It was heavier than she'd expected. The metal edges were polished smooth, yet the cold, hard texture transmitted itself without reservation. Lu Chenyuan produced a few more items. Wrist cuffs, ankle cuffs, and rings for above the elbows and knees. He picked up a wrist cuff and offered it to Su Wantang. The metal was cool against the warmth of her palm. The leather lining the inside of the cuff was soft and delicate, but the metal structure on the outside was hard and heavy. In one spot on the cuff, there was an almost invisible tiny indentation, embedded with a magnetic device. "These cuffs," Lu Chenyuan said, "pair with corresponding magnetic points on your latex suit. When they get close, they'll automatically snap shut and lock. The magnetic force is adjustable in three levels." He picked up the black remote control and placed it on the workbench. "This is the control remote. It can control all your gear. Each of you also has a sub-remote for self-control, but it can't unlock anything." Lu Chenyuan's fingers hovered over the surface of the remote. "Here, for the nipples," he said, tapping a spot. "Vibration, pulse, mild electric shock. Intensity from one to ten. You said you were afraid of pain earlier, so we can start with one or two." His finger moved to another area. "Here, the chastity device," he said. "The two metal rods can be controlled independently. Insertion depth, frequency, rhythm, rotation, vibration, electric shock. Everything can be preset. You're afraid of getting hurt, so I'll control the depth and frequency within your acceptable range. But the insertion itself," he looked at her, "is part of your fantasy, isn't it?" Su Wantang nodded, her earlobes burning. "Here," Lu Chenyuan's finger moved to the edge of the remote, "for the neck collar. Your latex suit has a hidden collar at the neck, just like Ruoyi's. Tightening speed, pressure value, duration are all adjustable. You fantasized about being choked, and this collar can simulate that feeling, but more safely and controllably." He put down the remote and his gaze fell on Su Wantang's face. "All these functions can be controlled remotely. That means, once you put on this gear, your body's reactions—nipple erection, vaginal contractions, the onset of orgasm, breathing rhythm—theoretically, all of it can be dictated by me." He paused. "This is what you saw when you were peeping, what Lin Ruoyi experienced." His voice was calm. "Now, it's laid out before you. Your version." She wanted it. She wanted to be encased in that smoky pink latex suit, wanted the magnetic cuffs to lock her wrists and ankles, wanted the remote to control her nipples and vagina, wanted the collar to slowly tighten around her throat. She wanted to experience the breakdown and climax she had fantasized about countless times, all within complete restraint and control. She looked up at Lu Chenyuan. "I..." Her voice trembled slightly, but it was clear. "I want it." Lu Chenyuan looked at her, his eyes behind the lenses unfathomably deep. After a few seconds, he nodded slightly. "Good," he said. Then he stood up, walked to her side, and gently placed a hand on her shoulder. "Next, I'll have Ruoyi teach you how to put it on." His voice was close, his breath fanning her ear. "It might be a little difficult the first time, but she'll help you, get you accustomed to it." Su Wantang's body trembled slightly, but it was from something else—a vast, impending sense of fulfillment, and the accompanying, faint dizziness. She knew, from this moment on, some things could never be undone. She complied. Her hands were clasped behind her back, wrists pressed tightly together. In that instant, she heard a faint click. It came from her own wrists. She lowered her head, seeing the surface of the latex on the inside of her wrists. The edges of the almost invisible indentations there were now emitting a faint blue light. Then she felt a gentle suction, as if something invisible were pulling the insides of her wrists towards each other, then pressing them together, locking them. Her hands were cuffed. Behind her back, wrists together, immobile. Before she could react, two more muffled clicks sounded from her elbows. The indentations on the outside of her elbows simultaneously lit up blue, and a stronger pulling force squeezed her arms towards the center. Her elbows were forced together, her forearms and upper arms folded into a tight embrace, her shoulder blades clamped backward, her chest involuntarily thrust forward. Her arms were doubly locked behind her back, her elbows forced straight, her wrists and elbows all secured by magnetic cuffs. Her shoulders were externally rotated to their limit, pulled back, her chest completely protruding forward. Then it was her legs. A suction came from the insides of her thighs, pulling her legs together. Then her ankles. With a click, her ankles were locked together. She could only move in tiny shuffling steps, or stand still, unable to stride. The entire process took less than ten seconds. Su Wantang stood in place, arms locked behind her back, legs together, ankles secured. The only parts of her body she could move were her head, neck, fingers, and toes. Every other part of her body was locked by the magnetic cuffs, as if she were trapped in an invisible cage. She tried to struggle. The cuff around her wrists immediately tightened a little, the edge of the latex digging into her skin, bringing a clear sense of pressure. She stopped struggling, and the pressure slowly eased, but didn't completely return to its original position—as if warning her: struggle more, and it will get tighter. "Don't struggle," Lu Chenyuan's voice came from behind her, steady, without inflection. "The more you struggle, the tighter it gets. That's the nature of magnetic cuffs." He walked in front of her, stopping two steps away, his gaze sweeping over her entire body again. Su Wantang stood before the mirror, arms locked behind her back, legs together, ankles secured. This posture exposed her body completely to his gaze—her chest high, her back straight from the pull of her arms, her hips slightly arched. The smoky pink latex, in this pose, stretched every curve of her body to its limit. The metal rod inside the chastity device was still working, entering and exiting her body at that constant, mechanical pace. Each thrust was amplified by her inability to shift her position to dissipate the stimulation, forcing her to receive it all. Pleasure slowly built within her, like water being added to a glass, drop by drop. It hadn't overflowed yet, but the water level was steadily rising. Then she felt the vibrator on her nipples activate. It was pulsed—vibrating for three seconds, stopping for two, then vibrating for three again. Each time it activated, she would tremble slightly, her nipples hardening rapidly beneath the latex, forming two distinct peaks. "When you were peeking before," Lu Chenyuan began, his voice still calm, "you saw Lin Ruoyi tied to this chair." Su Wantang's throat tightened, and she nodded. "You also saw her reactions during edge control. Being forced to the brink of orgasm, then stopped, then forced to the brink again, stopped, until she broke." Lu Chenyuan released the button. All stimulation ceased instantly. The vibrations stopped, the thrusting halted, and the mechanical hum in the room fell silent. Lin Ruoyi's body froze mid-air. As if paused, her waist remained arched, the swell of her lower abdomen at its peak before slowly receding. The trembling in her thighs turned into spasmodic twitches, spreading from her thighs to her calves. Her mouth hung open, but no complete sound emerged, only a guttural "huk-huk" of air escaping her throat. Then the breath escaped her, and she went limp, her body crashing back onto the platform. Her chest heaved violently, and the wetness between her legs expanded another circle on the black marble surface. Lu Chenyuan waited a few seconds. Then he pressed the button again. The vibrations and thrusting resumed, faster than before. Lin Ruoyi's body jolted as if electrocuted, her moans laced with a sob. She reached her peak reaction faster this time, her body tensing again, her waist arching once more. Lu Chenyuan released it again. "No—!" Lin Ruoyi's plea sounded piercingly sharp in the quiet room. Her body fell into that stiff state again, all pleasure building just below the brink, yet denied release. The liquid between her legs had already flowed to the edge of the platform, dripping onto the carpet. Tears welled from her eyes, mixing with sweat and tracing paths into her temples and neck. The third time. The thrusting pattern switched to an alternating rhythm, her front and back passages invaded in turn, with no moment of respite. Lin Ruoyi's whimpers turned into continuous, tearful pleas: "Master... please... let me... let me go..." Lu Chenyuan didn't stop. He made her wait at the precipice of the third climax for a long time—Su Wantang watched Lin Ruoyi's abdomen heave more and more violently, watched the trembling in her thighs turn into spasms of her entire lower body, watched her face flush red, tears and saliva mingling as they streamed down, watched her hands, bound behind her back, struggle in vain, her wrists chafing against the metal edges of the magnetic cuffs, leaving faint red marks. Then he released it again. Lin Ruoyi let out a cry of utter defeat. She collapsed onto the platform, her body convulsing, her crying turning into broken sobs. Sweat soaked her hair, clinging to her cheeks and neck. The back of her latex suit was drenched, sticking to the hollow of her spine. Su Wantang stood two steps away, watching it all. Her palms were sweating, and a hot dampness spread between her thighs. Though the metal rod inside her chastity device wasn't activated, the sensation of being filled felt acutely present. She watched Lin Ruoyi lie limp on the platform, her body convulsing from the unreleased pleasure, watched the puddle of wetness spread from between her legs to the edge of the platform, watched tears and saliva mix and flow down her jawline. Fear poured over her like ice water—if it were her lying there, how many times could she endure? But at the same time, a hotter desire surged through her veins: she craved that feeling of being pushed to the limit and then pulled back, that sense of losing control, her body no longer her own but a plaything in another's hands. Lu Chenyuan pressed the button again. This time, he didn't stop. The vibrations and thrusting simultaneously escalated to an intensity Su Wantang had never experienced. Lin Ruoyi's body sprang up from the platform, her waist arched to its extreme, the swell on her abdomen heaving violently, her thighs spasming intensely, her fingers clenched tightly behind her. Her mouth opened wide, but no sound escaped—then, the pleasure accumulated over three times burst forth like a dam breaking. A stream of glistening liquid sprayed from the edge of the chastity device's guard, splattering onto the black marble platform, creating a dense pattern of droplets. It was followed by a second stream, then a third, mingling with her screams of release as she climaxed, with the violent, almost frenzied tremors of her entire body. She collapsed onto the platform as if her bones had been removed, only her heaving chest and intermittent spasms remaining. Lu Chenyuan turned off the remote. He held the remote in his palm and turned to Su Wantang. "Now, it's your turn." "Alright," she stepped back half a pace, appraising Su Wantang. "Kneel up straight, let me see." Su Wantang straightened her back, shoulders back, hands clasped behind her. The smoke-pink latex cinched her waist into a narrow curve, her breasts forming two rounded mounds beneath the material. Her thighs were pressed together, the indentations of the cuffs at her groin gleaming faintly under the light. Lin Ruoyi nodded, returned to her position, and knelt again. She raised a hand, adjusting the hidden collar around her neck. Her fingers traced the seam of the latex, confirming the collar's placement. Then, she brought her hands behind her back, wrists together, aligning the elbow cuffs. "Wait a moment," she suddenly turned her head, looking at Su Wantang. "Your left wrist, turn it inward another half turn." Su Wantang rotated her left wrist, adjusting the angle of the cuff. Her fingers brushed against Lin Ruoyi's forearm. The moment the latex touched, a faint "hiss" escaped, the characteristic sound of thin latex rubbing together. Then came a "click." The smoke-pink latex and the midnight black latex pressed together. The cuffs at the inner thighs met with a "click," their legs locked together. Both women froze for a moment. Their hands were locked behind their backs, their legs together. The magnetic cuffs pulled them towards each other, shoulders bumping, chests pressing. The swell of breasts under the smoke-pink latex pressed against the equally full curve under the midnight black latex. The bases of the nipple vibrators on both sets of breasts pressed against each other, the hard metal edges digging into soft flesh. Su Wantang's breathing quickened. She could feel Lin Ruoyi's body heat radiating through the two layers of latex, slightly warmer than her own. The magnetic cuff at her groin pulled taut, her inner thighs pressed against Lin Ruoyi's, the edges of the chastity plate guards scraping against each other with a faint metallic whisper. Lin Ruoyi didn't struggle. She tilted her head, looking towards the entrance of the display area. A blurred silhouette stood there – a suit, glasses, a black remote control twirling between fingers. Lu Chenyuan said nothing, walking up and stopping at the edge of the platform. He looked down at the two of them awkwardly connected, pulled by the magnetic cuffs so their shoulders were pressed together and their thighs tangled. Then, he raised a hand and tapped the main remote twice. The magnetic cuff on Su Wantang's other wrist activated, clicking onto Lin Ruoyi's elbow. Lin Ruoyi's ankle cuffs followed suit, locking onto Su Wantang's calves. One cuff after another snapped into place, locking them from wrists to elbows, from thighs to ankles. Su Wantang's left side was pressed flush against Lin Ruoyi's right, the angle of their lean towards each other widening, breasts crushing breasts, lower bellies pressing against lower bellies, the chastity plate guards jammed tightly together. They knelt on the platform, locked into a pose that was both mutually supportive and mutually restraining. Su Wantang's chin rested on Lin Ruoyi's shoulder, and she could smell the clean cedarwood scent emanating from under the latex on Lin Ruoyi's neck, and a fainter, deeper hint of sweat. Lin Ruoyi's exhaled breath fanned across her cheek, warm and steady. Lu Chenyuan pressed the remote's start button. Both their bodies activated simultaneously. The nipple vibrators on Su Wantang's chest began to vibrate, and Lin Ruoyi's started at the same second. A low-frequency hum resonated through the two layers of latex, traveling from Su Wantang's nipples to Lin Ruoyi's and back again. She felt Lin Ruoyi's nipples harden beneath the latex, pressing against her own, hard and hot. The metal rods inside their chastity devices began to thrust simultaneously. The rhythm was perfectly synchronized, the stroke length identical, the depth the same. Two bodies were being penetrated by the same mechanical device at the same frequency. Su Wantang could feel Lin Ruoyi's abdomen rising and falling against her own, the rhythm of the movement perfectly in sync with the impacts she was experiencing internally. Each time the metal rod reached its deepest point, both their lower abdomens tightened simultaneously, their chastity plate guards colliding with a soft "ding." She could hear Lin Ruoyi's breathing right beside her ear. Short, wet, accompanied by the muffled thuds of rapid thrusting. "Mmm... mmm..." Lin Ruoyi's voice, squeezed from her throat, was faint, as if she were forcing herself to keep her breathing steady. Su Wantang's mouth was open, her own gasps mixing in, making it impossible to tell whose moan belonged to whom. Lu Chenyuan's finger slid across the main remote. The nipple vibrators switched from low-frequency vibration to pulse mode, three beats on, two beats off. Both women jolted simultaneously, their chests pressing even tighter, nipples against nipples. The hum of the vibrators, layered through the two thicknesses of latex, synchronized in frequency, making the soft flesh beneath their breasts tremble. The metal rods inside their chastity devices switched to alternating thrust mode. One in, one out, their vaginas and anuses being impacted in turn. The rhythm of their abdominal movements became a complex interplay – when Su Wantang's vagina was being penetrated, Lin Ruoyi's anus was being filled, and when Lin Ruoyi's vagina was being deeply entered, Su Wantang's anus was taking the impact. Their bodies were like two components linked by the same mechanical system, simultaneously enduring staggered stimulation, their breathing completely disrupted. Su Wantang turned her head, her face pressing against Lin Ruoyi's cheek. The surface of the midnight black latex was cool and smooth, as was the smoke-pink latex. The contact area between the two layers of latex created a finer friction sound in the sweat. She could see the distinct angles of Lin Ruoyi's profile, her eyelashes fluttering slightly, her lips parted, saliva spilling from the corner of her mouth and dripping onto her own shoulder, then sliding down the black latex surface into the gap of the clasp near her collarbone. Lin Ruoyi turned her eyes and looked at her. She said nothing, just looked. The metal rods inside their chastity devices continued to operate at the same rhythm, their bodies trembling under the continuous stimulation, thighs pressed against thighs, the latex on their inner thighs soaked with sweat. The moisture seeping from Su Wantang's legs mixed with the moisture seeping from Lin Ruoyi's, flowing down their tightly fitted thighs, forming a small, reflective shallow on the black marble platform. Lu Chenyuan pressed the third button. The collars tightened simultaneously. Both their breaths were choked off at once. Su Wantang's neck arched back, as did Lin Ruoyi's, their backs of their heads bumping together, hair tangling in their sweat. The feeling of suffocation made her consciousness hazy, leaving only the continuously operating metal rods in her body, the vibrators on her nipples, and a similarly trembling body heat transmitted through the latex. The collars released. Air rushed violently into their lungs. Su Wantang gasped, tears welling up, sliding down her nose, dripping onto Lin Ruoyi's shoulder. Lin Ruoyi was also panting, the violent heaving of her chest transmitted through the latex, gradually overlapping with the rhythm of her own chest. "Perhaps while you're typing, pouring water in the break room, or talking to others," he said, pocketing the remote. "Your body needs to learn one thing – not to endure stimulation, but to remain normal under stimulation, like Lin Ruoyi." The eighty-eighth floor was still quiet in the early morning, with only the faint hum of the air conditioning vents in the hallway. Su Wantang sat down at her desk and opened her laptop. The smoky pink latex suit clung tightly to her skin beneath the business suit. Her collar was concealed by a silk scarf, and the indentations from the magnetic cuffs on her wrists were hidden by her long-sleeved shirt. From the outside, she looked like any ordinary secretary. At 10:15 AM, as she went to deliver documents, the nipple vibrator on her chest activated. It wasn't the low-frequency vibration with a warning she'd experienced before, but a direct jump to medium intensity. The two silver-gray bases buzzed violently under the latex, her nipples becoming engorged and erect within seconds, pressing hard against the thickened layer of the suit. She paused for a moment, nearly dropping the folder, and then tightened her grip on her arm, continuing to walk. She met an old colleague from the finance department, Xiao Chen, in the hallway. He nodded and greeted her, and she returned the nod with a steady smile. During the afternoon's cross-departmental meeting. Lin Ruoyi was presenting a PowerPoint, and Su Wantang sat in the corner taking notes. A familiar mechanical whirring sound came from deep within her vagina – the dual metal rods began to thrust simultaneously, also at medium intensity, not aggressive but rhythmic. The inner sides of her thighs tensed, her leg roots trembling slightly under the table. Her fingers paused on the keyboard for a few seconds, she took a deep breath, and continued typing. When Lin Ruoyi's gaze swept over her, she lowered her eyes and kept typing, as if nothing had happened. It wasn't until dusk that she experienced what was described as the "random collar" for the first time. She was standing in the break room, pouring water into a cup, when the hidden seam of the smoky pink latex around her neck suddenly tightened. Her throat was constricted, and a hoarse gasp for air was squeezed from her trachea. She gripped the edge of the counter, her knuckles turning white. After more than ten seconds, the collar loosened, and air rushed into her lungs. She coughed, picked up her cup again, and saw her face reflected in the mirrored stainless steel sink – except for the faint blush on her earlobes, her expression had returned to normal. The next few days continued with this rhythm. The collar would tighten and loosen in the hallway, elevator, and at her desk, while the chastity device would activate without warning during meetings, phone calls, and while typing. Su Wantang learned to slow her breathing when her throat felt constricted and to subtly shift her weight to the other leg when her vagina was being penetrated. After 8 PM, the secret room. Under the warm white light of the collection room, Lin Ruoyi helped her check the fit of the latex suit, applying new lubricant to her elbows and the backs of her knees, areas prone to dryness. On the central circular platform in the display area, Lu Chenyuan would begin the combination training. It usually involved straight-arm bondage with magnetic ankle cuffs. Her wrists and elbows were attached to the magnetic points on the platform, and her legs were cuffed together. Then, the collar and chastity device would be activated simultaneously. The collar would tighten at medium intensity, restricting her breathing, while the dual metal rods in the chastity device would thrust at a fixed, high frequency. He would time her from the side, seeing how long she could maintain the position without faltering. After several rounds of training, she began to get used to finding an angle in the shoulder ache of straight-arm bondage that she could sustain longer, pressing her hip weight onto her heels to relieve pressure on her lower back. When the collar tightened, she would shallow her breaths and slow them down to avoid panic. During the thrusting of the chastity device, she wouldn't clench her thighs or hold her breath, allowing her body to absorb the impact with the rhythm. The intensity increased by one notch each day. One night, after the training session, Lu Chenyuan set the chastity device to high power and paused just as she was nearing orgasm, waiting a few seconds before resuming. She knelt on the platform, panting, her inner thighs slick with fluid, but her posture didn't break. "Good. Tomorrow, collar practice will be during a meeting." The next day, it happened during a meeting. As Su Wantang was answering a department's question, the collar tightened without warning – medium-high intensity. Her voice changed in her throat. She paused, cleared her throat gently, and finished the rest of her sentence in a steady tone. The finance director opposite her didn't notice anything unusual. After the meeting, Lin Ruoyi whispered in her ear, "Your neck turned red when it tightened just now, but your expression didn't change." Another day passed, and Lu Chenyuan announced after the evening secret room training that she could face the previously most dreaded combination alone: the collar tightening at medium-high intensity combined with the chastity device's extreme depth thrusting, for ten minutes. She was secured to the side of the display platform by magnetic cuffs, her arms bound behind her, her legs pulled apart by magnetic force. This time, she didn't struggle. She adjusted her breathing to a shallow, slow mode, allowing her pelvis to naturally absorb the impact. Lu Chenyuan watched the clock. She reached orgasm with one minute left, her abdomen contracting violently, fluid surging over the edge of the protective pad, but her upper body posture remained completely stable. He turned off the remote and said, "From now on, the frequency of the collar tightening will decrease, but the intensity will be unpredictable. The chastity device may activate at any time in any mode. What you need to do is not to endure, but to remain as usual in any state – no matter where you are, or who you are talking to." Su Wantang knelt on the platform, panting, sweat trickling down her neck and into the grooves of her collar clasp. She lowered her head and saw her legs still twitching slightly beneath the protective pad. She looked up at Lu Chenyuan again and nodded. The next morning, the collar tightened once in the break room, once by the printer, and once in the elevator. One of those times, she was standing and talking with two colleagues from other departments. The chastity device activated intermittently at noon and in the afternoon. Midway through a meeting in the evening, the dual rods suddenly began thrusting in an alternating rhythm – she took notes while suppressing her moans into her breaths. She began to feel a strange duality: her body was constantly on the verge of being used, yet her outward appearance was more like that of an ordinary, competent secretary than ever before. Sometimes, she would go into a restroom stall to adjust her scarf and collar. Her fingertips would brush against the hidden seam under the latex on her throat, recalling her gasps when the collar tightened last night – then she would re-tie her scarf neatly and push the door open, returning to her workstation.

Her arms were bound behind her in a "back-handed Guanyin" pose, hands clasped together, forearms pressed tightly against her upper arms. The hemp rope was wound from her wrists to her forearms, then to just above her elbows, each strand cinched tight. A transparent latex suit encased her body from neck to ankles, coated with lubricant on the inside, shimmering with a slick sheen under the cold white light. The reinforced bra cups pushed her breasts high and full, the openings revealing dark brown nipples and wide areolas. Her nipples were engorged and erect, hard points centered on the areolas. She wore ballet stilettos, with impossibly thin, high heels and flat tips, forcing her insteps into a complete arch, her entire weight pressing down on her toes and the balls of her feet. Her calf muscles bulged noticeably from the constant tension, and fine beads of sweat had formed on the back of her legs, visible through the latex. A breathing control mask covered her face, a silver metal piece over her mouth and nose, with black tubes extending to a small pressure regulator behind her. Inside the mask's valve, mist could be seen pulsing with her breaths. Her chastity device was made of transparent crystal, the plate fitting snugly against her pubic bone. Two thick metal rods were clearly visible inserted within, their tips pressing against her cervix and anus. These rods were considerably thicker and longer than her own, and their fine textures were visible through the crystal casing. The lower edge of the plate pressed against her labia majora, squeezing the fleshy lips slightly open on either side, allowing the tender pink edges of her labia minora to peek out from the gap between the plate and her skin, clinging to the inner wall of the crystal. Lu Chenyuan stood beside the treadmill's control panel, holding the black main remote. He glanced at Shen Qingyi, uttering no extra words, merely gesturing with his chin towards the empty space in front of the treadmill, indicating she should stand there. The treadmill's speed began to increase. Shen Qingyi's feet quickened their pace within the ballet stilettos, her toes curling and extending inside the tips. The Guanyin bind prevented her from swinging her arms for balance, and with each increase in stride, her upper body swayed slightly. Her breasts jiggled and swung within the openings, her nipples tracing arcs in the air, their areolas deepening in color from the engorgement caused by the movement. Lu Chenyuan pressed a button on the remote. The dual metal rods within the chastity device began to thrust, their frequency synchronized with the treadmill's speed. The faster the belt ran, the deeper and more forceful the thrusts became. Shen Qingyi's knees bent, her back leg faltering in the stiletto, her toes desperately gripping the shoe tips. Beneath the transparent latex, her lower abdomen began to rise and fall rhythmically above the metal plate, her cervix being repeatedly struck by the metal tip. He retrieved a whip from a rack beside the treadmill, a slender black leather whip with a non-slip leather-wrapped handle. He moved to a position behind Shen Qingyi and flicked his wrist lightly. The whip cut through the air, landing with a sharp crack on the back of her thigh, just below her buttocks. A bright red mark immediately appeared under the latex, extending from below her gluteal line to above the hollow of her knee. Shen Qingyi gasped, a muffled inhale coming from the mask, and her pace immediately quickened. The regulator valve on the breathing controller turned with a "beep." The aperture of the mask's breathing valve narrowed, halving the air intake. Shen Qingyi's breaths became hoarse, rapid gasps within the mask, her chest expanding violently. The latex-clad breasts became even more engorged from the lack of oxygen, her nipples swelling to a deep purplish-red. "Crack." The second whip landed on the back of her calf, lower than before, striking the most tensed part of her calf muscle. Another red mark appeared under the latex, running parallel to the first. The thrusting frequency increased again. The dual metal rods accelerated their in-and-out motion within her, alternately stretching her vaginal opening and anus. The tender pink mucosa of her vaginal walls, stretched by the metal rod, slightly everted with each outward stroke during the high-speed thrusting. The folds of her anus were repeatedly flattened and retracted by the other rod, its textured surface scraping against her intestinal walls. The labia majora, pressed by the lower edge of the crystal plate, began to exude fluid. At first, a small drop of clear liquid appeared, then more and more, trickling down the edge of the plate to her inner thighs, leaving sticky trails on the transparent latex. Her legs began to tremble noticeably, the pressure on her toes within the ballet stilettos reaching its limit. The treadmill speed increased by another notch. She had to run faster, but her breathing was restricted, her arms bound. "Crack!" The third whip landed squarely on the center of her buttocks, the sound as sharp as a snapping branch. A whip mark, wider and redder than the previous two, immediately appeared under the latex, stretching horizontally across her right buttock from above her gluteal cleft. "Mmmph~!" A muffled groan escaped the mask, tinged with clear pain and trembling. Her waist involuntarily arched, but Lu Chenyuan simultaneously pressed the remote, activating the high-frequency electrostimulators on her nipples and perineum. Under the transparent latex, the silver-gray electrode pads could be seen clinging to her skin. Electrical pulses shot across the edges of her areolas, her nipples jerking violently with each shock, their color shifting from deep purple to dark red and back to deep purple. Her labia majora contracted spasmodically under the plate, her labia minora quivering against the inner wall of the crystal. Her back and abdominal muscles spasmed simultaneously, her movements becoming distorted, yet she still tried to keep pace with the running belt. Lu Chenyuan pressed another button. The dual metal rods within the chastity device switched to an alternating thrusting mode, the rhythm so fast it was almost continuous, impacting her cervix and rectum simultaneously. Under the transparent latex, the muscles of her abdomen and waist heaved violently. Her labia majora squeezed out a large amount of clear fluid from under the plate, flowing down her inner thighs. Her clitoris protruded from the upper edge of the plate, its pink tip engorged to a deep red, pulsing continuously with the electrical shocks. The breathing controller dropped another level, the air intake reduced to less than a third. The gasps in the mask turned into short, struggling squeaks, her chest heaving, her breasts thrashing wildly in the openings, her nipples swollen to a deep purplish-red.

Su Wantang placed the contract on her desk, her fingers brushing the edge of her mask. The black silk fabric was damp from her exhaled breath. A layer of sticky warmth, a mixture of saliva seeping from the gag's vents and unfinished semen, had accumulated on the inside of the mask. The skin on her chin felt itchy from the moisture. She removed one earring and pulled the mask down to her chin, revealing the swollen lower half of her face. The pearl-white gag filled her mouth, the freshwater pearls glowing softly under the light. Yes, because yesterday during the inspection, there was almost no semen left. So today, Su Wantang was punished again for a full day. Su Wantang picked up a sticky note from the desk, uncapped her pen, and wrote a few words before pushing it over: "There's a latex bitch by the office desk." Lin Ruoyi's gaze lingered on the paper for a moment before she looked up at her. "Bitch? Tied next to the chair leg?" She nodded. The pen moved on the paper again, writing: "Wearing a full black latex suit, limbs folded and stuffed into leather latex casings, only able to crawl on elbows and knees." She pushed the note in front of Lin Ruoyi, her fingers tapping the paper. The metal rod deep inside her vagina was still vibrating on a low setting, her cervix feeling slightly numb, causing her wrist to tremble slightly as she wrote. Lin Ruoyi turned her chair to face Su Wantang, her arms crossed over her chest. "Her face? Can you see her face?" Su Wantang shook her head and squeezed out a muffled word from her throat, blocked by the gag. "Mmm... mask." She gestured to the outline of her head with her hand, drawing two circles at the eye level, then a cylindrical shape at the mouth. The pen continued on the paper: "Wearing a dog-shaped mask over her head, eyes covered by opaque lenses, mouth plugged with a gag. A collar is attached to a metal chain beneath the armrest of President Lu's chair." Lin Ruoyi's eyelashes drooped, her fingers tapping a gentle rhythm on her knee. "What about below?" she asked. Su Wantang's pen tip paused on the paper. She completely removed the mask from her chin and placed it on the desk, revealing her entire face, distorted by the gag. Then she lowered her head and continued writing: "There's a round opening at the crotch, exposing her vulva completely. A transparent vibrator is inserted into her vagina, thrusting in and out. Her labia majora are spread open, revealing the deep red flesh inside, which is pulled in and out between the ring-shaped protrusions on the vibrator's shaft with each thrust. A pink bullet vibrator is attached to her clitoris with medical tape. The bullet vibrator makes her clitoris shake, causing it to swell into a deep pinkish-purple. A dog tail butt plug is inserted into her anus, its metal base stretching her sphincter. The entire circle of folds around her anus is flattened, revealing only a ring of taut, pinkish skin." She stopped writing here, her Adam's apple bobbing. The metal rod inside her chastity device suddenly increased from low to the next setting, its ring-shaped protrusions scraping deeper against her vaginal walls. Her cervix was lightly bumped. She let out a soft, muffled "Mmm~," her thighs pressing together lightly beneath her skirt. Lin Ruoyi took the densely written sticky note and read it from beginning to end. Her thumb lightly traced a few lines of text on the paper, her lips pursed. She looked up at Su Wantang. "Limbs folded into leather casings, black latex suit, gold buckles," she said, not as a question, but repeating key details. Her eyes suddenly narrowed. Su Wantang noticed this expression; she recognized it. Lin Ruoyi would squint like this when piecing together scattered fragments. Lin Ruoyi slowly placed the note back on the desk, her finger tapping the top line, "latex bitch," a faint curve forming on her lips. "I know who it is." Su Wantang immediately picked up her pen and quickly wrote on the paper: "Who?" Lin Ruoyi took the pen from her hand and gently placed it by the pen holder. "I can't tell you." Su Wantang froze. Her lips moved inside the gag, squeezing out a muffled "Why..." Lin Ruoyi moved her chair forward half an inch and lowered her voice. "It's not that I don't want to tell you, it's that I can't."

She aimed the tip of the feeding tube at the still-pulsing throat opening and gently pushed it in. The silicone tube slid over the indentations of her tongue, over the swollen mucosa of the palate, and into her throat. The red, swollen, tender flesh of her throat parted further to accommodate the silicone tube. The throat muscles spasmed immediately at the intrusion, constricting around the tube and sucking it deeper with a forceful pull. A muffled "Guh~nnn~" escaped the dog's throat, and her entire body twitched slightly under the restraint of the latex suit. Su Wantang pressed the syringe plunger with her thumb, pushing slowly. The liquid food squeezed out from the side holes at the tip of the feeder, directly into her trachea. The dog's throat muscles immediately began to swallow passively. From the outside, the section of her trachea under her jaw could be seen to writhe around the transparent silicone tube, once, then again, the rhythm forced by the speed of the liquid food, completely out of sync with her own breathing. A faint, muffled gurgling sound accompanied the flow of food, rising from deep within her trachea. The swallowing motion pulled at her entire neck, and tiny droplets of fluid formed on the transparent silicone tube, thin white liquid secreted by the throat mucosa, carried out by the food. Su Wantang continued to inject at a steady pace. The dog's throat muscles continued to writhe rhythmically around the feeding tube. The rhythm of the vibrator inside her vagina had been set to medium by Lu Chenyuan's remote control before he left. The ringed protrusions on the vibrator's shaft continued to scrape the vaginal walls with regular in-and-out movements, the tip of the metal head hitting her cervix with a dull ache. Her pelvic floor's swallowing reflex was linked to her pelvic muscles, and with each passive swallow, the vaginal walls spasmed and tightened for a moment. The deep red inner mucosa of her labia majora, pressed by the chastity plate, gently bounced and retracted with each spasm. The tender red slit of her labia minora, peeking out from the edge of the plate, also quivered slightly with each swallow. Su Wantang watched the dog's clitoris twitch violently under the transparent medical tape. The tip of the deep pink nub swelled to a reddish-purple under the high-frequency vibration of the bullet vibrator. A drop of clear arousal fluid seeped from the edge of the tape, which she wiped away with her thumb. About halfway through the injection, the dog choked. Her swallowing reflex couldn't keep up with the flow rate of the liquid food. Some of the food surged back up, choking into her trachea. A series of rapid, dry coughs erupted from her throat, and her upper body jolted violently within the latex suit. Su Wantang immediately stopped injecting and pulled the feeder out half an inch. The dog coughed violently, her throat clamping onto the silicone tube. The airflow from her coughs, carrying fine white foam from the liquid food, sprayed onto the tip of the tube and dripped down the tube wall onto her jaw and the silver buckle of her collar. She cradled the dog's chin to keep her airway clear. After a few seconds, when her coughing subsided, she slowly pushed the feeder back in and resumed injecting, this time at a much slower pace, pausing for a moment after each push to allow her throat enough time to swallow before continuing. The dog seemed to adapt to this rhythm, her throat muscles beginning to synchronize with the inflow of food. Her abdomen swelled slightly under the latex suit, indicating that the liquid food was filling her stomach down her esophagus. As the vibrator inside her genitals gave its final thrust, Lu Chenyuan remotely increased its speed by one notch. Her cervix was hit sharply by the metal head, and she let out a deep, hoarse "nnn~" from between her throat and the feeding tube. The inner thighs, squeezed tightly by the latex suit, spasmed, her labia majora repeatedly opening and snapping back. Her labia minora twitched and slapped against the metal inner wall at the edge of the plate. Her clitoris, under the medical tape, leaped from deep pink to dark red, squeezing out a small drop of clear mucus that glistened at the edge of the tape. The fine folds around her anus, tightened by the dog tail plug, were stretched into a taut, light brown ring, occasionally quivering with the aftershocks of her cough. The last tube of liquid food was injected. Su Wantang slowly withdrew the feeder. The transparent tube slid out of her trachea. The empty silicone tip still had a mist-like residue of liquid food and the slippery secretion from her throat mucosa clinging to it, pulling a thin silver thread that stuck to the latex on the dog's chin. Her throat opening was now empty, the previously flattened throat opening slowly contracting back, revealing the deep red throat mucosa still trembling slightly within. She unscrewed the feeder and placed it on the plate, then picked up the dildo-gag she had removed earlier. Holding it by the base, she slowly reinserted it. The glans slid completely over the indentations of her tongue, pushed into her throat, and the base sealed snugly against the edges of her lips. The dog let out an extremely lazy, long whimper from her throat, her head tilting back slightly, resting against the chain of her collar. The lower half of the canine mask was reattached. The cylindrical gag, shaped like a muzzle, firmly sealed her mouth. The airflow from the ventilation holes carried a faint scent of the liquid food mixed with stomach acid, a hint of milky sourness. Su Wantang released her hand from her chin, allowing her to lie back down on the carpet. The vibrator's intensity had been reduced to medium-low after feeding, but the bullet vibrator continued to vibrate at high frequency, her clitoris still twitching under the tape. Her knees, curled within the latex suit, trembled slightly. The black latex shoulder blades, scuffed by grit, showed large patches of sweat-soaked and then dried areas as she lay on her side. Su Wantang put the empty liquid food bag and used syringe into the equipment bag. As she stood up, she realized her inner thighs were also a bit damp. The inside of the chastity plate's guard had secreted a considerable amount of bodily fluid due to the continuous low-frequency vibration, which had soaked through the thin layer of pale pink latex on her inner thighs. The next morning, Lin Ruoyi took a leave of absence. Su Wantang was in the secretary's office, filing the previous day's contracts, when she received the internal message. Lin Ruoyi's avatar was gray, and the message box contained only one sentence: "Feeling unwell, taking one day off." She stared at the words for a few seconds, a strange sense of unease settling in her heart. Then the intercom rang. Lu Chenyuan wanted to see her in his office. Pushing open the heavy wooden door, the cold white ceiling lights illuminated the area around the desk. Lu Chenyuan sat in his chair, flipping through a document, and tapped the edge of the desk with his finger. The black dog was curled up in her usual spot, lying on her side on the dark gray carpet to the right of the chair, her limbs folded within the latex suit, the black faux fur tail of the dog tail plug gently sweeping the carpet. Next to her was a white dog. Pure white latex covered her from neck to folded ankles, gleaming with a moist, pearlescent sheen under the cold white light. Her limbs were also folded and tucked into a latex suit, the suit itself a matte silver-white, with silver metal buckles, mirroring the gold buckles of the black dog. She was kneeling beside the black dog, her ass raised high, her vulva exposed through the circular opening in her crotch, directly in Su Wantang's line of sight. The white dog's canine mask was also made of white latex. The muzzle-shaped cylindrical gag protruded from her mouth, the edges of the ventilation holes slightly wet with saliva. The eyeholes were opaque silver lenses, and the erect triangular dog ears twitched slightly. A white leather collar around her neck was attached to a silver metal chain, the other end of which was clipped to another metal ring at the bottom of the chair's armrest. "Feed these two today," Lu Chenyuan said without looking up, tapping the remote control with his finger. The vibration of the chastity belt inside Su Wantang rose from low to medium, and her cervix was gently bumped by the metal rod. She bit her lower lip to steady her breathing. "The feeding tubes and liquid food bags are in the drawer. Feed the white one first, then the black one." Su Wantang took the feeding tube and two bags of nutritional liquid from the drawer. She squatted in front of the white dog, reached behind the dog's head, and her fingertips found the silver metal buckle securing the lower half of the mask above the collar. She gently pressed it open. The lower half of the mask came off, revealing her mouth, filled with the gag. She gripped the base of the silicone dildo in the white dog's mouth and pulled it out. The shaft was warm from being held, covered in slippery, clear saliva, pulling a long, thin strand that stuck to the white latex on her chin. As the entire length was withdrawn, the glans retreated from her throat, pulling a ring of tender red mucosa from her trachea, which slowly retracted. The white dog let out a very low, muffled "woo~" from her throat, her jaw trembling slightly. Su Wantang looked at the mouth that was stretched open and couldn't close, at the deep indentations on her tongue left by the dildo, at the still-pulsing red, swollen, tender flesh of her throat opening. That unease surged again. This mouth shape, the contour of this jaw, this instinctive swallowing motion after being stuffed for so long. She placed the dildo on the corner of the table, which had been covered with paper towels. She unscrewed the syringe plunger and attached the hollow feeding tube connector. She pulled back the plunger to draw half a tube of light beige liquid food, then aimed the tip of the feeding tube at the pulsing throat opening and gently pushed it in. The white dog's throat muscles immediately constricted around the silicone tube. A muffled "Guh~nnn~" came from deep within her trachea, and her entire upper body twitched slightly under the restraint of the latex suit. Su Wantang pressed the plunger with her thumb, pushing slowly. The liquid food poured into her trachea from the side holes at the tip of the tube. The dog's throat muscles began to swallow passively, the section of her trachea under her jaw writhing rhythmically around the transparent silicone tube. The swallowing sound was very faint and muffled, rising from deep within her trachea. As she injected, she looked at the white dog's face. The mask covered most of her face, leaving only her mouth and chin exposed. The edges of her lips, stretched open by the gag for a long time, were faintly red. There were fine white marks at the corners of her mouth, dried saliva mixed with stomach acid. With each swallow, her jaw muscles twitched slightly, and the white collar around her neck also trembled. Su Wantang lowered her voice and softly called out, "Sister Ruoyi?" The white dog showed no reaction. Her throat muscles continued to swallow rhythmically. The silver lenses were fixed on Su Wantang's face, her pupils completely obscured, making it impossible to discern her focus. A faint, steady stream of exhaled air puffed from the small ventilation holes on either side of her muzzle, the rhythm unchanged.

The door to the chamber. The hum of the treadmill hit the ears first, followed by the sharp crack of a whip slicing through the air, a "snap" landing on flesh and skin, mixed with a muffled whimper from a gagged mouth. The cold, white lights of the secret room blazed on. Three treadmills were lined up facing the door. The one on the left was empty, while the middle and right machines were running at high speed. Two bitches were chained to their respective treadmills. The black one was in the middle, her limbs folded and tucked into restraints, forced to support herself on the treadmill belt with her elbows and knees. Her spine, encased in black latex, arched into a trembling curve, her ass high in the air, her vulva exposed through the circular opening in her rear restraint, spread wide in her crawling position. Her labia majora were pulled open by a vibrating dildo, revealing deep red inner folds, their edges glistening from constant friction. Her labia minora squeezed out from the gaps in the protective plating, pressing against the metal belt, twitching with each jolt of the moving treadmill. Her clitoris, taped to a pink bullet vibrator with medical tape, was pulled taut from its hood, swelling into a deep purple nub, bouncing with every step and causing the edges of the tape to bead with fine, clear fluid. A dog tail plug was cinched tightly in her anus, its metal base stretching her sphincter into a smooth, light brown ring. The edges of the ring repeatedly stretched and contracted with the exertion of crawling, oozing a circle of clear fluid mixed with lubricant. The white one was on the right, her body also folded into a kneeling crawl. Her pure white latex gleamed with a pearlescent sheen under the lights, and her buttocks and thighs were already crisscrossed with vivid red whip marks. She had been whipped less than the black bitch, but her crawling rhythm was noticeably less steady and slower. Her moans from her throat were a dull "woo~ woo~嗯~," and she ran a little faster with each lash. Su Wantang froze at the doorway, her fingers still gripping the doorknob. Lu Chenyuan stood with his back to her between the two treadmills, holding the slender black leather whip. From her angle, she could see his shirt sleeves rolled up to his forearms. As his wrist turned, the whip tip drew an arc through the air, landing with a sharp "crack" on the plump buttocks of the black bitch. The flesh beneath the black latex twitched violently. The black bitch's entire upper body sagged with the impact of the whip, her front leg restraints nearly slipping off the treadmill belt. A sharp, broken "Ah~嗯~" burst from her gag, and the treadmill dragged her backward. She scrambled desperately to regain her position in the middle of the machine. The white bitch beside her, hearing the crack of the whip, twitched her ears and crawled faster. The white latex on her calves scraped against the treadmill belt, producing fine white rubber dust. Lu Chenyuan didn't turn around, merely saying, "Close the door and come here." Su Wantang closed the door and walked to a position two steps to his side. Her chastity device was still vibrating on its medium setting, the metal rod inside her vagina gently bumping against her cervix. The latex at her inner thighs was already damp with bodily fluids, but she couldn't focus on that. Her eyes were fixed on the black bitch on the treadmill. The black bitch's four folded limbs trembled violently within her restraints. The treadmill was moving fast, and she had to keep crawling to avoid being dragged off. But with each landing of her elbows and knees on the belt, her support weakened a little more. The inside of her thigh restraints had developed a layer of light gray rubber creases. Her buttocks and the backs of her thighs bore seven or eight whip marks. Some were older, swollen into pale pink bands with the redness at the edges faded. Others were recent, raised and bright red, extending from the peak of her buttocks down to above her knees. Each one was clearly visible through the black latex. "Crack!" Another lash landed directly above her buttock cleft. The whip tip precisely bit into the indentation between the base of the dog tail plug and her tailbone. The black bitch sprang upwards, a heart-wrenching "Ah~" erupting from her throat. Her rear leg restraints slid halfway off the treadmill belt. The collar yanked her metal chain, and she realized her body had flipped onto its back. She lay on her side on the treadmill belt, the friction scraping away the sweat and moisture from the new whip marks on her buttocks, tearing the edges of the swollen red welts into tiny flakes of peeling skin, revealing tender red flesh beneath. The vibrator slipped partially out of her vagina, still rotating, coated in thick, clear lube. Her labia majora were pulled open to their limit, the deep red inner mucosa pressing directly against the rough texture of the treadmill belt, rubbing. Lu Chenyuan pressed the remote control, and the treadmill stopped. He walked to the black bitch, who was lying on her side, and used the whip to lift her chin, which was covered by a dog-like mask. The silver lenses were fogged with sputtered saliva. Broken whimpers of "woo~嗯~woo~" escaped her gag, her trachea convulsing wildly within the collar restraint, her entire chest heaving. "Fallen halfway through the distance," his voice was soft. "If you don't finish tonight, we'll continue tomorrow." He placed the whip on the treadmill's handrail, bent down, and pushed the still-rotating vibrator on the treadmill belt back into the black bitch's vagina. As the rod was pushed back in, the wet, red mucosa of her everted labia majora were pushed back in with it, clamped beneath the protective plating. The black bitch squeezed out a long "Ah~嗯~" from her gag, her leg roots and perineal muscles spasming simultaneously. Then he unfastened the metal chain of the white bitch beside her and gestured for her to crawl down. As the white bitch collapsed onto the floor on her side, her limb restraints still trembling, her white latex chest and abdomen were covered in mist from evaporated sweat. The vibrator beneath her crotch continued its silent in-and-out motion, her labia majora flipping open and snapping back, her labia minora parting and closing at the edge of the protective plating, her clitoris bouncing under the medical tape, squeezing out a small drop of clear fluid with each bounce that dripped onto the treadmill belt, warmed by the machine's hot air. Lu Chenyuan placed the remote control on the console and said to Su Wantang, "Go take care of the black one. Make her finish the remaining distance." Then, he took the collar chain of the white bitch, who was already slumped on the floor, panting, and slowly walked towards another part of the secret room. Su Wantang walked to the black bitch's side and squatted down, her fingers gently touching the whip-scarred side of her buttocks. The black bitch's labia majora were still everted, the wet red mucosa pressed against the treadmill's pattern. Her clitoris, under the continuous vibration of the bullet vibrator, had already swollen into a dark purple nub. The sphincter beneath the dog tail plug's base continued to contract tirelessly. She reached out and grasped the metal chain of the bitch's collar, helping her up from the treadmill belt and repositioning her into a kneeling crawl. Every muscle in the bitch's body was trembling, but as soon as she was back on all fours, she instinctively began to crawl, her elbows and knees grinding against the treadmill belt, now slick with her own sweat and fluids. Su Wantang's hand, holding the leash, did not pull. She simply walked with her as she crawled slowly. The treadmill was stopped, and the bitch's crawling speed was very slow, her every step trembling. But the moans escaping her throat had gradually subsided from whimpers to a rhythmic "woo~嗯~." Su Wantang watched the vibrator still thrusting inside her, the constant rhythm of her labia majora flipping open and snapping back, the clear fluid squeezed out after countless bounces of her clitoris under the tape, flowing down the treadmill's texture to form a thin, wet trail. Finally, she spoke softly.

As Su Wantang's gaze drifted down, she saw a circle of pink remote controls strapped to the woman's thighs. Transparent elastic bands held the remotes firmly in place mid-thigh, their indicator lights blinking with a faint green glow. Her crotch was open-design, and through the mesh of her stockings, her outer labia were visible peeking over the edge of the protective flap, their tender red inner surfaces glistening moistly under the light. Her inner labia pushed out from the edge of the flap, quivering slightly with the subtle movements of her body. The vibrator inside her was clearly working – her voice carried a distinct, suppressed tremor as she spoke. Lin Ruoyi stepped forward and asked, "Excuse me, where can we watch the match?" As she spoke, she jiggled her bound arms. "The, the viewing area… is, is to the left up ahead… Ah~ the second, door…" She pointed forward intermittently, her cheeks flushed with an unnatural crimson. The distinct outline of her nipples was visible beneath the patent leather bustier. A faint trail of transparent liquid marked her inner thighs, flowing down a short distance from the opening in her mesh stockings, catching the light under the spotlights. The backs of her knees also trembled slightly, clearly indicating she was enduring internal stimulation while maintaining a standing posture. "Ah~ go straight, that way… then turn left… Mmm~ you'll be there…" Her trailing words were interrupted by a strong vibration, causing her to jolt slightly. A short "Mmm~" escaped her throat, and after regaining her balance, she pointed in the direction of the passage. At this moment, a young man approached, glanced at the bunny girl a few times, then walked over and adjusted the remote controls on her thighs, one by one, turning them up. "Ah~ too… too high~~" Despite her words, the bunny girl showed no signs of resistance. Su Wantang walked a few more steps forward. At the corner of the passage stood a woman in a red qipao. The qipao featured a high slit, opening all the way to her waist, revealing two long legs clad in flesh-colored stockings. Her hands were bound with coarse rope, starting from her wrists, wrapping around her upper arms, over her shoulders, and tied in a tight cross knot behind her back – thoroughly trussed. The knots dug in tightly. Her ample breasts strained against the neckline, forming a semi-arc, round and full, their contours clearly visible through the fabric. She also wore a "STAFF" badge around her neck. Her inner thighs were similarly bound with a circle of pink remote controls attached by transparent elastic bands, their indicator lights pulsing rhythmically. She leaned against the wall, her eyes slightly red. To ensure they didn't get lost, Lin Ruoyi asked again. "The, the viewing area~ go up the stairs, from there… Ah~ the second floor…" Her voice was broken by the frequency of the vibrator inside her, requiring her to pause and catch her breath every three or four words. Her tongue trembled, and the vibrator inside her body was rhythmically striking her cervix. Her knees, peeking from the hem of the qipao, were slightly pressed together, and the stockings on her inner thighs were already stained dark with moisture. The circle of pink remote controls was strapped to her upper thighs, their indicator lights pulsing on and off at a medium frequency. "Mmm~ up ahead, there's a sign… Ah~ you'll see… their, their competition area when you get there…" Her eyelashes fluttered intensely. After speaking, she bit her lower lip with her teeth, suppressing the moans that threatened to escape back into her throat. A small amount of transparent liquid seeped from the slit of the qipao at the base of her thighs, flowing down the stockings to the inner curve of her knees. Su Wantang nodded and quickly walked past the qipao-clad woman, turning the corner. At the end of the passage stood a woman in a JK uniform – a white shirt, a dark blue pleated skirt, a striped tie, and long, straight black hair cascading over her shoulders. A silver metal gag was attached to her neck, like an expanding lock fitted into a collar, completely immobilizing her head from turning left or right. Her hands were cuffed behind her back with a pair of silver handcuffs. Below the pleated skirt, a section of her thigh, clad in white thigh-high socks, was visible. A circle of pink remote controls was also strapped to her thigh. Her voice trembled, and when she said "the third door," her voice was suddenly cut off by a moan welling up from her throat – the vibrator had clearly switched to a more intense setting inside her. Her pelvis tilted forward slightly, her calves tensed, and it took several breaths before she recovered, her cheeks flushed, her nipples forming two distinct hard points beneath her white shirt. Su Wantang thanked her and continued forward. Turning the corner at the end of the passage, the view suddenly opened up – they had reached the second-floor viewing area. The viewing area was semi-open, with several rows of seats placed in front of a railing, already occupied by some people. Through the railing, one could overlook the entire main arena. Shen Qingyi's black latex suit was highly conspicuous at the edge of the spotlighted area. She was kneeling face down beside a pillar, with many female submissives in K9 gear nearby. At the edge stood a woman in a white, one-piece uniform. The uniform was form-fitting, covering her from her neck to the base of her thighs, with an open crotch design. Her hands were cuffed in front of her with a pair of metal handcuffs, and the same pink remote controls were strapped to her thighs. She was directing a few newly arrived spectators to their seats. Su Wantang sat down at a spot by the railing, with Lin Ruoyi sitting beside her. From here, they had a clear view of Shen Qingyi's competition zone, as well as the preparations of other contestants and staff under the warm yellow lights. As she looked down, her gaze swept over the remote controls strapped to the white-uniformed woman's thighs, their indicator lights blinking rhythmically.

When her shirt was removed, Su Wantang saw that the woman's arms were positioned incorrectly. Her two arms were brought together behind her back, her wrists locked by a pair of metal handcuffs, the edges of the cuffs lined with soft padding to prevent skin abrasion. Her upper arms were tightly bound by coils of hemp rope, the rope digging into the flesh of her arms, leaving faint red marks on her pale skin. Her forearms and upper arms were pressed almost together, bent back at an extreme angle and secured behind her. The chain of the handcuffs also connected to a braided cord, which ran down between her shoulder blades and was secured at her waist. Her fingers were usually hidden behind her back, her movements controlled by the form-fitting prosthetic shell that extended from her shoulders to her fingertips. Made of lightweight, matte white plastic, it featured precise pivots and micro-motors at the joints, allowing her fingers to perform intricate actions like gripping, rotating, and manipulating. The woman gently spread her arms outward, the prosthetic joints sliding smoothly without any stutter or delay. She then brought her arms back together, the prosthetics falling naturally to her sides, perfectly synchronized with her body's movements. "The top floor only uses this method—they are completely restrained to the point of being unable to move independently, with prosthetics replacing their daily activities." The woman neatly folded the white work uniform top and placed it on the edge of the workbench, then stood quietly, waiting for Lu Chenyuan to continue speaking. Her prosthetic fingers were gently clasped in front of her, the joints emitting a very faint motor sound. Su Wantang's gaze fell upon her bare back—her skin was very pale, her shoulder blades slightly protruding due to her arms being bound behind her. The outline of her arms, secured by rope and metal cuffs, was clearly visible. The hemp rope started at her wrists, wound around her forearms, and coiled up her upper arms, tied in a firm knot below her shoulder blades. The rope dug into her skin, leaving deep red imprints on her fair complexion. Her arms were pressed almost completely together, the edges of the metal cuff rings showing soft padding, but faint indentations were still visible along the edges of the padding. Lu Chenyuan walked behind her and lightly tapped the intersection of the rope just below her nape. "Her lower body is also folded and bound in the same way," he said, his fingers slowly sliding down her spine, stopping at her waist. The woman didn't move, merely cooperating by leaning forward slightly to make her waistline more prominent. Her work pants were loose white fabric, and nothing appeared unusual from her waist down. Lu Chenyuan bent down, hooked his fingers under the waistband, and pulled them down. As the work pants slid down to her knees, Su Wantang's gaze was fixed. The woman's legs were folded from the top of her thighs—her thighs were bent backward, her calves pressed against the back of her thighs, her knees fully bent. At her ankles, a thick black nylon strap securely fastened her ankles to metal buckles on the back of her thighs. Several elastic straps extended from the base of her thighs to the backs of her knees, locking the folded position of her entire legs. Her legs could not be straightened at all, and she was completely unable to stand or walk. However, inside her outer pant legs, she supported a white matte prosthetic identical to the one on her upper body. The prosthetic extended from her hips, covering the shape of her entire thighs, knees, calves, and feet, with precise metal pivots and micro-motors at the joints. As Su Wantang saw these mold-like shells and restraints intertwined over her skin, a clearer impression emerged—the prosthetics were not worn over her limbs but were fitted like a layer, conforming to the contours from her hips to her arches, snugly encasing her bent knees and ankles to support her standing posture. Lu Chenyuan pulled the work pants back into place. "Her three holes down below," he straightened up, gesturing vaguely in the air, "are also all filled." Su Wantang remained silent. But she followed his gaze to the woman's crotch. Through the fabric of the white work pants, nothing unusual was visible. But as she looked closely, she noticed a small, very faint shadow on the fabric at the base of her thighs—several thin tubes extended from her perineum, running along the inside of her thighs and hidden within the grooves on the inner side of the prosthetic shell. "Each hole is fitted with a powerful vibrator and a multi-functional egg vibrator set to maximum. Her training requires her to endure these stimulations at all times during work hours, without anyone noticing, and without reaching orgasm." The woman stood quietly, her prosthetic fingers gently clasped in front of her, her expression calm, her breathing steady. "They are professionally trained female submissives. Before entering a scheduled work state, these individuals have undergone rigorous adaptation training. When they are typically played with, they can moan freely, but if they show any expression of enjoyment or loss of control during work hours—" he paused, "the vibrator deep within their uterus will deliver a severe electric shock." Su Wantang's gaze fell upon the woman's flat abdomen. There was no indication of anything working inside her, but she noticed that the woman's prosthetic fingers, clasped in front of her, tightened almost imperceptibly when she heard this, then relaxed. "Her breasts have also been modified," Lu Chenyuan continued without turning around. "After regular hormone injections, she can lactate at any time without needing to be pregnant. During exhibitions or special missions, dedicated staff will come to collect it regularly." Su Wantang's gaze shifted to the woman's exposed breasts. They were full, her areolas a deep brown, large and covered with fine granular bumps. Her nipples were erect, darker than her areolas, shaped like two ripe mulberries. The edges of her areolas showed distinct needle marks and tiny scabs—likely from long-term injections or catheter insertions. Lu Chenyuan looked at the woman. "You, demonstrate it." The woman walked to the workbench and picked up a glass bottle containing half a bottle of milky white liquid. She unscrewed the cap, brought the opening close to her left breast, and gently squeezed the area around her areola with her fingers. A few drops of milky white fluid seeped from the tip of her dark brown nipple and dripped into the bottle. Her expression remained unchanged, her prosthetic fingers steadily holding the bottle.
