As soon as his father left, he used his own cock to fuck his bound and blindfolded mother into becoming his exclusive

On a sunny afternoon, Mother Liu Mei and Father were preparing to make love. Suddenly, Father took out several pairs of handcuffs and a blindfold. Father: "Mei Mei, shall we play some fun games today? How about you wear a blindfold and have your hands and feet cuffed? To add some spice." Liu Mei was a little delighted, not expecting her husband to be so playful. She readily agreed. Liu Mei said: "Husband, you're quite the player. I've never tried this before, so let's do it!" Father helped Mother undress, then cuffed her hands and feet to the four corners of the bed, spreading her out like a starfish. He then blindfolded her and was about to kiss her when the phone rang. Father: "It's a work call. Something seems to have come up at the company. I'll be back soon." Liu Mei felt disappointed and a little angry, but she understood that a good wife should support her husband's work. Mother: "It's okay, husband. Go take care of it. Since it'll be quick, I'll just wait for you like this. Remember, your wife is waiting for you." Father nodded and walked out, talking on the phone. Neither of them knew that this scene was witnessed by Han Li, who had been peeking from outside the door. Now that Mother's eyes were covered and her hands and feet were bound, what would Han Li do? Han Li gently pushed open the bedroom door. The first thing he saw was the sight of his mother, Liu Mei, bound to the bed. Her fair skin glowed alluringly in the dim light. Her tall figure was tightly bound by ropes, her full breasts and curves of her hips clearly visible. Her long black hair was scattered on the pillow, like a splash of ink. This contrasted sharply with her fair skin. The blindfold covering her eyes concealed her charming gaze, yet

Between white and translucent, a gradient was naturally formed due to varying degrees of dampness, distinct and clearly visible. After admiring her "masterpiece" for a moment, Liu Mei gently parted her lips and stuffed the entire pair of panties into her mouth. Her soft, sensual lips tightly enclosed the panties, her cheeks bulging slightly from being stuffed full. Her eyes narrowed slightly with excitement. Compressed by her mouth, the fluid from the panties immediately soaked her entire oral cavity. The original foot odor was quickly replaced by the pungent, musky scent of the discharge, mixed with the arousal fluid secreted from her vagina due to the vibrating dildo. She gently bit down on the panties in her mouth with her teeth, savoring the fluids on them, a look of intoxicated satisfaction on her face. Then, she picked up the tape that Han Li had specifically bought for binding her and gagging her. She wrapped it around her mouth, layer by layer, completely sealing it shut. Perhaps due to a lack of experience, her movements were a bit clumsy and stiff. This simple act of taping her mouth shut took her a good half hour to finally complete. She smoothed the tape with her fingers, confirming her mouth was completely sealed. Liu Mei then picked up the stockings, still emitting a strong odor, the tape, the vibrating anal plug, and a pair of handcuffs that her husband had previously used to spice things up, and which Han Li frequently employed for his various perverted games. She also retrieved a large block of ice from the freezer and placed it in a cooler box before slowly walking into the bathroom. Liu Mei entered the bathroom and approached the bathtub. She looked around, her gaze finally settling on two hooks nailed to the wall above the tub. These two hooks were at different heights, the higher one about 1.8 meters from the floor and the lower one about 1.2 meters, both firmly fixed to the wall. Liu Mei reached out and gently tugged on the hooks, meticulously checking their stability. Once she confirmed they were securely fastened and wouldn't easily come loose, she firmly hung the handcuffs on the lower hook. Next, she took out a large block of ice, wrapped in a clean mesh bag, from the cooler box and carefully hung it on the higher hook. Then, Liu Mei gracefully flipped herself into the bathtub and took out the anal plug she had prepared. She then skillfully dipped the anal plug into a small cup filled with milky white yam juice, extracted from fresh yams. The yam juice was viscous and had a faint, fresh aroma. When the anal plug was removed from the yam juice, its original flesh-pink surface was now evenly coated with a thick layer of milky white liquid. Looking at the anal plug coated in yam juice, Liu Mei couldn't help but recall that night when Han Li had given her an enema, the intense itching that had raged in her anus, and later, the indescribable pleasure when Han Li had penetrated her anus with that strangely shaped rubber rod. That intense pleasure, a mixture of pain, shame, and overwhelming bliss, made her involuntarily tremble again and a profound sense of excitement surged from the depths of her heart. She could no longer wait to experience that feeling again. Liu Mei spread her legs and slightly adjusted her sitting position, making herself more comfortable on the cold porcelain edge of the bathtub. Then, she picked up the anal plug coated in yam juice and began to slowly insert it into her continuously quivering, incredibly wet anus, made so by her previous sexual activity. "Mmm... Woo woo woo... Woo woo woo..." As the phallic-shaped anal plug's "glans" slowly pushed open Liu Mei's sphincter, which had become somewhat relaxed from her previous sexual activity, and penetrated her intestinal tract, the milky white yam juice coating the plug gradually adhered to her sensitive intestinal walls as the plug went deeper. Gradually, Liu Mei felt that familiar itching sensation slowly emerge from the depths of her intestines. As time passed, this itching intensified, becoming almost unbearable. Her face contorted in pain and discomfort, and her body writhed from the itching. "Hoo... Woo woo woo woo woo..." To alleviate the intense itching that was driving her mad, Liu Mei abandoned all pretense of grace and modesty. She began to roughly and frantically thrust the phallic-shaped anal plug in and out of her anus. The anal plug moved rapidly in and out of Liu Mei's anus, making a "plop plop" sound. The pleasure of anal sex made her completely lose control, and she let out low, suppressed moans, her breathing becoming rapid, her body trembling with pleasure. In less than a minute, Liu Mei's anus, through this frenzied thrusting, reached the peak of orgasm. Her already emptied, once again filled with pleasure, she was completely immersed in an ocean of ecstasy...

"Li... Little Li..., no, don't... Mom, Mom is still tied up... If, if someone finds out... what, what will we do..." At the hotel room door, Liu Mei timidly refused to step out, her voice trembling, her eyes filled with fear and unease, like a startled little rabbit. Liu Mei's hands were tightly bound behind her back, leaving red marks on her wrists. Her face was flushed with shyness and nervousness, her eyes darting away, unable to meet Han Li's gaze. Her lips trembled slightly, as if she were about to cry at any moment. Her body shivered with fear, like a frightened little bird. A few hours earlier, in the museum restroom, Han Li had thoroughly ridden Liu Mei, leaving her covered in sticky semen, her nether regions completely ravaged. To prevent Han Shuai Mao from discovering anything amiss, from sensing their unspeakable secret, Han Li had specifically found a nearby hotel, booked a room, so Liu Mei could clean herself up, rest, and recover her strength. It also served to conceal her swollen, tender nether regions, which were a result of being overused, thus preventing Han Shuai Mao from discovering their dirty secret. While Liu Mei was resting, Han Li, bored and browsing P-site for videos filled with wild fantasies and thrilling scenes, stumbled upon a tag called "Disguised Restraint" and became instantly intrigued. So, after Liu Mei woke up, he eagerly bound her slender, fair hands tightly behind her back. After repeated practice, Han Li's movements were now skilled and gentle, as if he were creating a work of art. "Don't worry, Mom, as long as you put on your clothes, no one will see that you're tied up. Let's go, our room time is almost up, we need to hurry and check out," Han Li said, gently helping Liu Mei into a beige trench coat. The coat was long enough to cover her hands bound behind her back, and also concealed her slightly red and swollen nether regions, a result of the prolonged sexual activity. Then, he placed a black leather collar around her slender, fair neck, nodded with satisfaction, and gently tugged on the leash attached to it, guiding her to follow him out of the room. "No... no... absolutely not... this, this collar... take it off, quickly!" Liu Mei pleaded, backing away desperately, trying to prevent Han Li from pulling her out of the room. Her heart was filled with fear and unease; she couldn't imagine what would happen if someone saw her like this. However, to prevent Liu Mei from resisting, Han Li had deliberately dressed her in sky-high heels. These heels made her look even more sexy and alluring, but also made it harder for her to maintain her balance. With the heels on, her feet were almost on tiptoe, her toes barely touching the ground. It was already difficult to stand steadily, let alone struggle with Han Li. Han Li only needed to give a gentle tug on the leash, and Liu Mei would lean forward, her center of gravity shifting, forcing her to follow Han Li's steps, just like a little dog being led by its owner, step by step, pulled by Han Li towards the room's exit. The expression on her face slowly shifted from panic and fear to reluctant acceptance. She had surrendered, or rather, from the very beginning, she had known that she could never truly fear Han Li... "Wait... wait! Little Li, at least... at least cover my face, okay?! Mom... Mom is a public figure! If anyone sees me like this... will I ever be able to show my face again?! No, that's not right, it won't just be about losing face..." Liu Mei made a final attempt at the hotel elevator entrance. She knew very well the severe negative consequences if her appearance were to be seen by acquaintances. This was not just a simple matter of "losing face," but could lead to imprisonment and even affect the reputation of her entire family. "Alright, alright, Mom, I'll grant you this last request. You can't ask for anything else later, or else I'll..." Han Li deliberately put on a helpless expression, his tone full of teasing, his words...

As she moved, her body arched back slightly, forming a graceful and seductive curve. Her chest slowly rose, revealing her full, ample breasts, bound tightly by black leather straps that seemed to contort them. With her hands no longer holding them, the beige trench coat's lapels parted like stage curtains, falling naturally to either side. A gap, about ten centimeters wide and filled with a deadly allure, began at her delicate, fair neck, extending downwards past her subtly undulating collarbones, grazing the skin on her chest that flushed slightly with excitement, and finally narrowing and converging between her tightly bound, high-swelling breasts, forming an alluring, inverted triangle of an "absolute domain." The pure moonlight, like a spotlight, fell precisely upon this exposed expanse of snow-white skin, making it appear even fairer, more delicate, and more translucent, as if emitting a faint halo, filled with an indescribable, eerie beauty that intertwined sanctity and lewdness. Just then— "Whoosh—" A perfectly timed night breeze, like a mischievous sprite or an invisible hand, carrying a hint of cool chill, brushed past her side with a gentle yet irresistible force. The hem of the trench coat, which had only been slightly open, was suddenly whipped open and blown aside by this unexpected gust of wind! In an instant— Liu Mei's body, hidden beneath the trench coat, naked, bound and restrained by black leather straps in a shamefully restrictive "Kikko-shibari" style, her voluptuous, gourd-shaped figure exuding a sense of eroticism and violent beauty—was thus—completely, unreservedly, starkly—exposed in this desolate, silent abandoned park, witnessed only by the cold moonlight and the chilling night wind! The black leather straps, like venomous snakes, tightly coiled and bound her plump, full breasts, leaving deep, heart-stopping indentations; they wrapped around her slender, soft waist, accentuating its fragility and making it appear even more impossibly small; they encircled her round, perky buttocks, compressing and deforming the elastic flesh into a more exaggerated, more enticing [X] shape; and even… even brutally and deeply dug into the most private, sensitive area between her legs, a mysterious triangle that had already become mired and slick with copious amounts of arousal fluid from her previous walking and friction! Due to her prolonged walking and the intense stimulation from the fear of being watched and the accompanying excitement deep within her, her vulva had already uncontrollably secreted a large amount of thick, slippery arousal fluid. This fluid trickled down the inner thighs, thoroughly soaking the black straps that tightly bound her [X]. Under the pale moonlight, they shimmered with an ambiguous and lewd sheen, emitting a rich, unique scent that mingled feminine body odor with a musky aroma. "Ahhh… it’s out… it’s completely exposed…" At this moment, Liu Mei's heart erupted in a silent scream, filled with both extreme shame and ultimate excitement! This sudden, perfectly timed night breeze, like a confederate of Han Li… or rather, like the fallen angel within her own heart, at the very moment she had completed her near-manic psychological preparation, had precisely lifted the last fig leaf, exposing her utterly lewd, outrageously perverse, and shameful appearance to this desolate expanse! And simultaneously… it had also laid bare, unreservedly, starkly—her dirty, perverse soul, already corrupted and twisted by lust and perverted fetishes! The intense sense of transgression, utterly contrary to societal morals and ethical principles! The extreme sense of crisis, of being discovered, stumbled upon, and gawked at, humiliated as a pervert and a madwoman at any moment! And… and that unprecedented absolute freedom, of shedding all worldly rules and moral constraints, of being able to indulge the darkest desires deep within her heart without restraint!

Her consciousness was torn to shreds, leaving only her body reacting instinctively, violently, as if on the verge of death! "Insane! I'm going insane! Han Li! Kill me! Please, kill me! It's… it's too intense! I can't stop! My pussy… my ass… my pee hole… they're all squirting! All trembling! All being played with! My nipples… they're going to fall off! I… I can't control it… my body… it… it's sucking… clenching… squirting on its own… like… like a runaway, squirting meat toilet! Whore! Bitch Liu Mei! You can't even control your own body! You deserve to be played until you're rotten like this!" The extreme fear was like the most solid ice coffin, rigidly imprisoning her instincts to scream and writhe wildly! She poured all her strength into her teeth, biting down hard on the soaked wad of stockings in her mouth, reeking of strong, sour foot sweat. Her teeth sank deep into it, almost piercing through! From her throat erupted muffled "wooo… mmm…" sounds, filtered by layers of tape, stockings, and a mask, sounding like the dying groans of a deep-sea leviathan! Beneath the bandages, every muscle in her body tensed to its limit, like steel wires stretched to the breaking point, trembling and spasming violently and at high frequency! This trembling was so intense that the static cling tape binding her emitted a faint, strained "squeak"! Every drop of liquid that fell was like a searing hot brand on Liu Mei's soul! She could clearly feel the warm wetness seeping through the man's not-so-thick cosplay fabric, reaching his skin! She could imagine the rapidly expanding, dark, and odorous wet patch on his back! She could even "hear" the sound of the liquid dripping, which, to her highly amplified hearing, boomed like a death knell! However, the cosplayer seemed completely immersed in the novelty of carrying a "high-tech, spasming" realistic doll, subconsciously attributing the warm dampness and faint odor on his back to "advanced lubricant" or a "biomimetic fluid simulation system." He might even think this "leakage" was part of pursuing "realism" – after all, Han Li had boasted earlier that the doll "squirts when it orgasms"! Han Li watched Liu Mei on the stranger's back, on the verge of collapse from the extreme stimulation he was remotely controlling yet forced to suppress, watched the liquid continuously dripping from her crotch, a testament to her degradation, and the playful, cold smirk on his lips deepened. Like a master precisely controlling a puppet, he gently slid his finger across the phone screen, switching modes again! This time, it was the ultimate pulse mode with three synchronized vibrators, featuring intense spasm induction and squirting simulation! "Buzzzzzzz—!!!" It was as if a bomb had detonated deep within Liu Mei's pelvis! Her vagina, rectum, and bladder were simultaneously hit with a devastating, synchronized blow! Under the pulses, the flesh within her vagina writhed and spasmed uncontrollably, greedily sucking, like countless mouths at the peak of hunger, desperately trying to swallow the vibrator that brought destructive pleasure, yearning to devour it completely! Her anal canal constricted and writhed violently, the muscles of her intestinal walls tightening madly, bringing a tearing pain and an intense urge to expel! Her urethral sphincter completely collapsed, and a torrent of urine, mixed with gushing arousal fluid, even more surging and scalding than before, erupted like a dam breaking, spraying out ferociously! The nipple vibrator seemed to unleash its strongest current simultaneously, making Liu Mei feel as if her soul were being sucked out through her nipples! "Ahhhhhh—!!! Together!! Pulsing together!!! Orgasm! I'm going to orgasm! I can't! I can't hold back!!! My pussy… is squirting! Spraying wildly like a high-pressure water gun! The flesh inside is greedily sucking… spasming violently… twitching… like a dying fish thrashing on a cutting board! My ass… clenching to its limit… my intestines feel like they're being torn by countless hands… intestinal fluid… mixed with… it's spraying out! My pee… pee and slut water… it's spraying out too! In huge gushes… spraying! Flowing! Dripping! My nipples… my nipples are going to split! My soul… is flying away! My whole body… feels like it's being thrown to the clouds and then slammed back down… the bandages… the bandages are going to break!" This time, Liu Mei's willpower, already stretched to its limit, shattered completely like fragile glass in the face of this destructive, synchronized ultimate pulse! Even though she still bit down hard on the wad of stockings in her mouth, locking all her screams deep in her throat and turning them into even more muffled, desperate whimpers, her body, bound by the bandages, uncontrollably, and with a far greater amplitude than before, bounced and arched upwards violently, like a death throe! Her waist bent backward into an astonishing arc, her tensed back muscles slamming hard against the man's back! "Mmph!"

She could feel the bladder wall stretched to its thinnest, the urine surging within like a flood about to break its banks, frantically battering the fragile gate – the urethral sphincter. Every heartbeat was like a heavy hammer striking this gate. She tried to control it, but the numb ache, the sting of the cold air, the boundless fear and shame, and Han Li’s palpable, oppressive gaze, all reduced her control over her body to an absolute zero. Under the dual torment of immense physiological pressure and psychological collapse, Liu Mei finally abandoned her last resistance. She took a deep breath, the complex aroma of cold air, her own sweat, urine, and feminine musk filling her nostrils. She concentrated the last bit of willpower she had, not to hold it in, but to… let go. With her mind, little by little, with extreme difficulty, she relaxed the tightly locked, rusty iron gate of her urethral sphincter… “Pfft… Sizzle—!” At first, it was just a small stream of warm liquid, propelled with great force, that shot out from her tensed urethra! It easily pierced the thin, delicate lace of the crotch of her lingerie, which had already been soaked and weakened by previous leakage, making a clear sound of liquid hitting fabric. This urine, carrying a fresh and potent ammonia stench, like an arrow, shot into the cold air, striking the thick rubber tire of the car’s front wheel! “Sizzle—Hiss…” Then, as if the dam had completely broken, the long-accumulated, massive amount of pale yellow urine surged out from Liu Mei’s urethra like a raging torrent, continuously and uncontrollably! The stream was no longer singular but formed a continuous, powerful jet of liquid, reeking of urine, violently washing over the black tire surface, emitting a loud, harsh, and incessant rushing sound! A large amount of urine struck the tire and splashed outwards. Some flowed down the tire’s curve, quickly gathering on the ground into an ever-expanding dark puddle that reflected a faint sheen in the dim light. Other droplets rebounded, splashing onto the inner sides of Liu Mei’s raised thighs, her knees, and her calves, bringing a warm yet utterly filthy sensation. A few drops even splashed onto her right leg, which was forced apart and trembling slightly. “Wuwu… Waa…” Liu Mei could no longer suppress it, letting out a complex whimper mixed with immense shame and physiological release. Her body trembled violently, like leaves in a gale. Her bound hands clawed at the ground behind her, her fingernails scraping against the rough concrete, making faint friction sounds. Her eyes were tightly shut, tears streaming down like an opened floodgate, mingling with sweat, dust, and splashes of urine on her face, leaving her a mess. She could clearly feel the sensation of urine flowing out – the burning heat as the stream stretched her urethra, the slight itch as the liquid washed through, and the indescribable, overwhelming shame that accompanied the release. Her trench coat had slipped to the ground. Her upper body was now bare, clad only in the humiliating lingerie and the red ropes binding her entire body. Her left leg was raised high, exposing the curves of her body in the night. Her private parts, forced open and spewing urine, became the focal point of this humiliating scene. The smell of urine in the air instantly became extremely strong and pungent, like an overturned ammonia bucket, overpowering the existing scents of sweat, rubber, and feminine musk, creating a nauseating aroma mixed with shame. This smell aggressively invaded Liu Mei’s nostrils, and each breath felt like swallowing a mouthful of scalding, poisonous shame. The urine continued to spray, in large quantities, the sound of it hitting the tire incessant. Liu Mei’s body, under the dual impact of immense shame and physiological release, became extraordinarily sensitive. She could feel the vibrator buried deep inside her, seemingly rubbing against her sensitive inner walls due to the continuous physiological reaction and the tremors of her body. Especially when a particularly strong stream of urine hit, her pelvic floor muscles would instinctively contract violently, a contraction that unexpectedly squeezed the vibrator inside her. Its rough, bumpy surface scraped against her delicate inner walls, sending waves of sharp, unexpected pleasure mixed with intense shame. “Mmmph…”

The fabric of her panties was already completely soaked through with her sweat, saliva, and the urine from her previous orgasm, becoming heavy and cold, clinging tightly around her nose and mouth. A potent, complex, and nauseating odor instantly permeated the air: the base note was the sharp, ammonia-like tang of fresh urine; mixed with the heavy, fermented-yogurt-like sourness of vaginal discharge; and the slightly sweet yet primal, briny scent of the clear lubricant she'd secreted during her climax. These scents, fermented by body heat within the confined space of the mask, formed an aggressive stench that instantly filled her nasal passages and throat. Han Li didn't simply stuff it back in. Instead, he roughly twisted the sodden lace fabric with his fingers, squeezing out some of the liquid, making it denser and harder, forming a thicker, more robust gag than before. He gripped Liu Mei's jawbone with one hand, forcing her mouth open in pain. Liu Mei's jaw joint let out a faint "click" as her mouth was forcibly stretched open. With his other hand, he unhesitatingly shoved the gag, reeking of potent female musk and urine, into her forced-open mouth! "Gag—ugh..." The intense sensation of a foreign object and the suffocating stench instantly overwhelmed her, making her stomach churn violently. Her body instinctively tried to arch upwards, but Han Li pressed her firmly back to the ground. The rough lace edges scraped against her gums, the base of her tongue, and the delicate mucous membranes of her inner cheeks, causing a burning, raw pain. The cold, fetid liquid saturating the fabric was quickly warmed by the heat of her mouth. The mixed scent of urine, strong female musk, and slightly sweet discharge spread like a physical entity, aggressively filling her entire mouth, nasal cavity, and even rushing down into the depths of her throat. Her salivary glands were intensely stimulated, producing copious amounts of saliva uncontrollably. She couldn't swallow, and it mixed with the murky liquid seeping from the gag in her mouth, forming a sticky, bitter concoction. This was not the end. Han Li then produced a black rubber strap, about two fingers wide and exceptionally strong. He cupped Liu Mei's cheeks, wrapped the strap around the back of her head, and then yanked it tight! The strap dug deeply into the soft flesh on either side of her mouth, almost embedding itself into her skin. It forced her lips to remain slightly ajar, unable to close completely, revealing a sliver of her mouth corners, wet with saliva and the panties' fabric. Saliva and the foul mixture from her mouth immediately began to dribble uncontrollably down her chin, following the contours of her slightly open mouth and the tight strap, leaving sticky, glistening trails on her smooth skin before dripping onto the cold concrete floor. With every labored breath, air could only enter through the gaps around the gag and her slightly parted lips, carrying the pungent stench of her own excrement. Each inhale felt like swallowing filth. Her throat itched intensely, but due to the tight strap and the gag, she couldn't even manage a clear cough, only emitting muffled, suppressed "huk... huk..." sounds. With the gag in place, Han Li's gaze turned to Liu Mei's lower body. He took out a new toy from his pocket – a black silicone product, longer and thicker than the vibrator used before. Its surface was covered in densely packed, spirally arranged ridges. Each ridge was distinct and firm, with a subtle granular texture at the tip, giving off an ominous matte sheen in the dim light. Its size was noticeably larger than the previous one, appearing inherently aggressive. Liu Mei stared at the object in terror, her legs instinctively trying to clamp shut, but her position, held down by Han Li, rendered her immobile. Han Li showed no intention of using lubricant. He directly used two fingers to forcefully spread apart Liu Mei's labia, which were slightly swollen and moist from fear and previous stimulation, but clearly not lubricated enough. Her clitoris and urethral opening, exposed to the cold air, contracted slightly from the sudden stimulation. Han Li's cool fingers probed the hot, wet entrance, roughly prying apart the delicate outer labia to reveal the deeper, dark red, slightly parted inner labia and the moist vaginal opening. Then, holding the cold, spiral-ridged black vibrator, he aimed the knobbed head at Liu Mei's vaginal opening, which had contracted from tension and dryness. Without any buffer, he twisted his wrist, and the thick, hard silicone tip forcibly pushed past the moist but insufficiently lubricated folds of her entrance! "Ugh ah—! Mmmph!" An intense, tearing pain exploded from her lower body! The unlubricated, thick vibrator forcibly stretched open the moist but not slippery vaginal entrance. The delicate inner lining was scraped by the rough ridges, causing a burning pain that far outweighed any pleasure. Liu Mei arched her body upwards violently in pain, like a drawn bow. A muffled, desperate whimper, choked by the gag, erupted from her throat, and tears instantly welled up in her eyes. However, Han Li's hands, like iron clamps, held her hipbones firmly, pinning her to the cold ground. With his other hand, he mercilessly continued to push the terrifying vibrator deeper. She could clearly feel the cold, spiral-ridged shaft forcibly stretching the inner walls of her warm, tight passage, scraping against every sensitive fold. The sensation of the ridges scraping was incredibly distinct, cold and rough. The vibrator was pushed all the way in, until its hardest, small-headed protrusions at the tip pressed tightly, with a sense of pressure, against the soft flesh of her most sensitive and delicate cervix. Her cervix, forcefully pressed by the foreign object, sent a deep, heart-stopping ache and pressure, as if her internal organs were being pushed upwards. Liu Mei's body convulsed uncontrollably from the intense internal stimulation. Her abdominal muscles tensed, and the vaginal walls contracted violently, attempting to expel the invading object. But this only caused the rough ridges to scrape more distinctly against her sensitive inner walls, bringing waves of peculiar, tingling soreness mixed with pain. Han Li seemed satisfied with Liu Mei's pained reaction.

"Timer, start." The heavy leather shoes, like a crown of shame, pressed down firmly on Liu Mei's head, bringing with them the potent scent of Han Li's feet and the unyielding texture of leather, subjecting her fragile neck to an unprecedented, immense pressure. She had to exert every ounce of her strength to maintain absolute stillness in her head and neck, preventing the shoe on her head from even the slightest wobble or tilt. Simultaneously, she had to support her body with her knees and palms, navigating the winding, flickering fluorescent line, beginning a arduous crawl. Every breath became a cautious act, the rise and fall of her chest strictly controlled, for fear of disturbing the precarious balance atop her head. The crawl began. It was like moving across a bed of thorns, each step accompanied by piercing pain and ultimate humiliation. Liu Mei had to accomplish three impossible tasks at once: crawl with her entire body weight supported by knees bound tightly with nylon rope; maintain the absolute balance of the sweat-scented leather shoes on her head; and constantly monitor the pressure readings on her knee pads – numbers that directly controlled the terrifying instrument ravaging the depths of her anus. On her knees, the cold silicone casing of the pressure sensor pads pressed against her skin. Each time her kneecaps struck the cold, hard concrete floor, the sensors precisely converted the impact into fluctuating digital readouts, projected in real-time onto the monitoring screen of Han Li's phone. For the first few meters on the relatively flat stretch, the pressure readings hovered around 30 kilograms. As the numbers changed, the large vibrator inserted deep into her anus began to hum. The vibration wasn't violent, yet it possessed a suffocating penetration. The hard protrusions covering the vibrator's surface, with each oscillation, relentlessly scraped against the delicate mucous membrane of her rectal wall, bringing waves of deep, aching fullness and a dragging pain, as if her internal organs were being churned. Her intestines spasmed uncontrollably, attempting to expel the terrifying invader, but this only caused the protrusions to rub more fiercely against the folds of her intestinal lining. Each vibration was accompanied by the sticky sensation of intestinal fluid being squeezed out, and an uncontrollable, false urge to defecate, forcing her to clench her anal sphincter with all her might. This continuous churning even extended to the adjacent vagina, stimulating the already scarred vaginal walls and the battered cervix, triggering waves of subtle, mixed with pain, numb pleasure. From Liu Mei's gagged mouth, the wad of lace panties soaked in urine and feminine odor continuously chafed her gums and palate as she crawled. The rough lace edges scraped her oral mucosa raw. The black strap dug deeply into the soft flesh of her lips, forcing them into a slight gap, unable to close completely. Her salivary glands were intensely stimulated, producing saliva at a frantic rate, but she couldn't swallow. It could only mix with the murky liquid seeping from the panty fabric, carrying a strong odor of urine and sour, feminine decay, forming a sticky, bitter concoction that continuously overflowed from her slightly parted lips. It slid down her chin, leaving deep crimson indentations, and dripped onto the concrete floor as she crawled, leaving intermittent, wet trails. With every labored inhale through her nose, she drew in the suffocating, foul stench of her own body. Each exhale was a desperate gasp, a suppressed "huk huk" sound. This odor drifted into the cool night air, mingling with the characteristic dust and oil smells of the parking lot, forming a unique, humiliating marker. Her gaze was fixed on the winding fluorescent green line near her ankles, her trajectory of shame. Above, Han Li's heavy leather shoes were like the sword of Damocles, pressing down on her scalp with the potent scent of his sweat, the stale leather, and the mixed, murky odor of dust and oil from the parking lot floor. The hard, cold edges of the shoes pressed against her skull, the rough texture of the soles rubbing against her hair. To maintain this precarious balance, she had to control every muscle in her neck and head with the precision of a finely tuned machine, her upper body held extremely low, almost parallel to the ground. This posture forced her buttocks to protrude high, lowering her center of gravity to prevent a fall. The hem of her windbreaker, due to this posture, had completely slid up to her waist, offering no further concealment. The cold night wind blew unobstructed across her forcibly parted buttocks, and the slightly contracting, pinkish-brown folds of her anus, stretched open by the large vibrator nestled between them.
