"The Celestial Knot" Extra Chapter

The side stories primarily cover the following: 1. Stories of Zhao Lingyun and his wife Tang Guoguo in the modern world. 2. Stories of the couple and their neighbors – three recent female college graduates. 3. Unseen stories of Zhao Lingyun and his many women in the cultivation world, not detailed in the novel. 4. Various bizarre experiences of the other women. Since Zhao Lingyun and Tang Guoguo's first taste of BDSM, the sensation had left them both with a lingering craving. Guoguo felt a shameful sense of being controlled. Although her hands weren't bound, having them held behind her back and pinned by her husband gave her a feeling of restraint, amplifying her helplessness. Coupled with the gag, rendering her unable to speak, she could only submit. While Guoguo was a self-media blogger, it didn't mean she was without pressure. Every vlog required careful selection of eye-catching outfits and constant brainstorming of plot ideas. Interacting with various cosplayers at conventions also left her mentally and physically exhausted. This feeling of safe control, shame, helplessness, and submission allowed her to release accumulated stress mentally. Physically, she didn't have to overthink; she just needed to follow her husband's rhythm, which made her very relaxed. In previous sexual encounters with her husband, although the pleasure was intense, the BDSM experience not only allowed her to enter the state quickly but was also incredibly stimulating, and the orgasm lasted longer than ever before. Zhao Lingyun, too, had discovered the pleasure of BDSM after that experience. This might be related to his work. Working a typical nine-to-five job, he was a skilled programmer at a tech company, but the workload was heavy. He had to report his daily progress to his team leader and sometimes worked late into the night. That experience allowed him to feel a sense of complete control, and to some extent, he felt a thrill from Guoguo's submission, even deriving pleasure from seeing her humiliated. After that, he rarely played video games. Instead, he spent time on foreign websites, searching for various bondage tutorial videos. He also bought many cotton ropes of different lengths on Taobao. For a beginner like him, cotton ropes were ideal as they wouldn't injure Guoguo. Subsequently, he selected some adult toys and attire. On Valentine's Day, February 14, 2025, Zhao Lingyun finished work, asked his team leader for leave, took a delicate gift box from his drawer, and went to a flower shop to buy a large bouquet of pink roses, planning to surprise Guoguo. He quietly opened the front door, put on his slippers, hid the roses behind his back, and peered into the living room. Seeing no one, he assumed Guoguo might be editing videos. He tiptoed to the study. The room contained only a laptop that was not closed; it was empty. He then walked towards the bedroom. Seeing the door ajar, he gently pushed it open and found his wife inside. She was wearing a futuristic Hatsune Miku costume and was fiddling with something in front of the vanity mirror. His heart leaped with joy. He tiptoed over and extended the bouquet of pink roses in his hand before his wife's eyes: "Happy Valentine's Day, wife!" His action startled Tang Guoguo greatly. Hearing her husband's voice, she let out a sigh of relief. Turning around, she lightly tapped Zhao Lingyun with her fist: "Oh, husband, you're so annoying! You scared me to death..." Seeing the pink roses her husband offered, Tang Guoguo happily accepted them and brought them to her nose, inhaling their fragrance: "So fragrant..." Zhao Lingyun took out the exquisite gift box from his pocket and handed it to Guoguo: "Wife, this is your Valentine's Day gift." Tang Guoguo was overjoyed. She put down the roses, took the gift box, and eagerly, carefully untied the ribbon. Zhao Lingyun then noticed Guoguo's attire. Her long hair had been dyed mint green and tied into two pigtails at the back, each secured with a black ribbon tied into a cute bow. She wore a sleeveless, high-necked top, made of an unknown material that clung tightly to her skin, accentuating her figure perfectly. Her chest, seemingly unburdened by a bra, swelled high, with the faint outline of two small peaks visible. Around her neck was a tie the same color as her hair. On each arm, she wore a separate long black sleeve, connected by a black lace strap that passed through the gap between her index and middle fingers, extending to the cuffs. Her lower half was clad in a black, layered mini-skirt, so short it barely reached the top of her thighs, with hints of mint green panties peeking through. Black thigh-high stockings encased her shapely legs tightly. On her feet, she wore black high heels, ten centimeters high, with soles and heels in a mint green color. Seeing his wife dressed like this, combined with her delicate and beautiful face, left Zhao Lingyun stunned. Was this still his wife?

"Put it on." The woman in leather handed her a collar with a chain attached. Ling'er crossed her arms, looking at her and shaking her head. The leather-clad woman stepped forward, grabbed her, and fastened the collar around her neck. With a "click," it fit snugly, clamping tightly onto Ling'er's neck. Ling'er wanted to resist, but she was no match for the woman. She blinked her large, wronged eyes at the leather-clad woman. "This is the last time. If you dare to disobey my orders again, you will be severely punished!" the leather-clad woman said coldly. "From now on, you will call me Master." "..." "Ling'er's only Master is her junior sister, Lingyun. This woman wants me to call her Master? Not a chance," Ling'er thought to herself. Suddenly, she felt a strong force pulling her forward. The leather-clad woman, tugging on the chain, looked down at the small woman who barely reached her chest, showing no hint of tenderness. "Everyone who comes here is like you at first. You'll get used to it. But before that, you need to learn to obey." She pulled the chain and walked out. Ling'er was dragged out of the stone room and into a corridor. Wooden doors lined the walls every few feet. She guessed that the rooms behind them were like the stone room she had just left. Soon, she was led into a luxurious room. The first thing that caught her eye was an intricately carved sandalwood screen, adorned with lifelike carvings of birds, flowers, fish, and insects. Walking around the screen, she saw a thick carpet covering the floor, woven with exquisite and complex patterns in vibrant colors. Portraits of beautiful women hung on the walls, but they were either bound by ropes or restrained by iron implements. The paintings were detailed and vivid, seemingly allowing one to feel the emotions of the women depicted. The entire room was filled with a faint scent of sandalwood. A bronze incense burner in the corner emitted wisps of pale smoke. The leather-clad woman motioned for her to lie down on the table. Seeing Ling'er still standing, she forcefully pushed her onto the large sandalwood table, pulling her hands apart and securing them to iron rings on the edges. She then spread Ling'er's legs apart and fastened them to iron rings extending from the table corners. Thus, Ling'er's hands and feet were spread and restrained, her buttocks raised as she lay prone on the table, unable to move. After a while, she felt the woman caressing her rear, which seemed to be coated with some liquid. The woman's fingers began to probe towards her anus. Ling'er panicked and felt ashamed. "No, you can't..." Despite her struggles and cries, the woman still inserted her fingers. Ling'er felt pain and a slight swelling in her rear, which was very uncomfortable. She writhed her hips. "Slap!" Ling'er felt a hard slap on her bottom. She had never been hit so hard in her life. Tears of grievance welled up, and she dared not move. Seeing that she no longer resisted, the woman's fingers delved deeper. Ling'er began to writhe her hips again, trying to stop her, but felt a burning pain on her bottom once more. After repeating this several times, both of Ling'er's buttocks were red. She seemed to have resigned herself to fate, lying on the table and weeping silently. The leather-clad woman nodded with satisfaction after fully inserting her fingers into Ling'er's rear, stirring them a few times. Then, she slowly withdrew her fingers. Ling'er finally felt as if something had opened up, no longer feeling that blocked sensation. Before she could catch her breath, she felt a cold object being inserted into her rear. She bit her lip, enduring it with all her might, large tears falling and wetting the tabletop. The leather-clad woman was holding a gleaming, rod-like object and was inserting it into Ling'er's nether regions. It was a rod-like object made of stacked spheres, about three fingers wide. The first small sphere was only one finger wide, and they gradually increased in size. The first small sphere slid into Ling'er's small opening with relative ease. But as the second sphere, which was larger, began to be inserted, the leather-clad woman applied a little force before the opening could slowly swallow the sphere. During the process, Ling'er moaned in pain. Every time a sphere was inserted, her eyes widened, and she let out sounds of "Mmm... Ah..." Only after the sphere was fully inside did she feel a little better.

For months afterward, Ling'er was taken away daily by the woman in leather for special training. One day, Ling'er was bound again by her. Brown hemp ropes coiled around her body like venomous snakes, her limbs twisted and pulled taut behind her back, suspended in mid-air in a posture of four hooves splayed. The ropes dug deeply into her fair skin, her full breasts squeezed to appear even more prominent. Her body formed a straight line, positioned before the waist of a mannequin. Her task today, in this very posture, was to make the mannequin ejaculate. It sounded simple, to make it ejaculate just once a day, but in reality, it was incredibly difficult. She was suspended in the air, unable to exert any force, and her small mouth was still half an inch away from the mannequin's cock. What frustrated her was that the mannequin was dressed in fine silk robes. First, she had to lift the mannequin's robe and remove its pants. Her lower body was threaded with a rope, a large knot tightly secured within her pussy, tethered to a loop at her waist. The other end passed through her anus and was held taut by the mannequin, stretched straight. Any slight movement of her body would cause the knot at her pussy to shift, rubbing against her labia, making her limbs go numb and sapping her strength. After a long while, Ling'er's mind finally conceived a plan: to swing her body, like a pendulum on a swing, and seize the opportunity to bite onto the mannequin's waistband. She felt a secret sense of pride, marveling at her own ingenious idea. However, after experimentation, this method proved difficult to execute. Although shaking her body caused the ropes suspending her to swing, the rope held by the mannequin also tightened and loosened with her movements. As if cooperating with the mannequin, she continuously pulled at the knot, which ravaged her pussy. Sensations surged through her like waves. Before she could even bite onto the mannequin's waistband, her body trembled, reaching its peak. Ling'er's body swayed gently in the air with the ropes, her breath coming in ragged gasps, unsure if it was from exertion or the recent climax. After a short rest, another brilliant idea struck her. She would imagine the mannequin before her as her master, Lingyun, and that she absolutely had to complete this test set by her master. With this thought, her heart filled with determination, and a resolute look gradually appeared in her beautiful eyes. She began to swing her body again, trying her best to ignore the stimulation from the knot within her, her mind solely focused on completing her master's task. Through her unremitting efforts, she finally managed to bite onto "Lingyun's" waistband and, shaking her head, pulled it downwards. The cock of "Lingyun's" lower body instantly sprang out. Ling'er let out a sigh of relief. Following the swing of the ropes, she took the cock into her mouth, then pulled away. She continued like this, back and forth, swinging like a pendulum in the air.

"Miss Ling, this servant will help you change." As Xiao Cui spoke, she stepped forward, reaching to remove Ling Yun's cloak. Ling Yun hesitated for a moment before finally nodding. Since Mo Zhaoran already knew her secret, there was no point in hiding it any longer. Xiao Cui gently unfastened Ling Yun's crimson cloak and then helped her shed the robe beneath. As the clothes fell away, Ling Yun's arms, bound tightly behind her back, and her nipples, firmly clamped, were revealed to Xiao Cui without reservation. Seeing this, Xiao Cui's expression remained unchanged, as if she were accustomed to such sights. There was no hint of surprise in her eyes, only a calm demeanor as she neatly folded the discarded clothes and set them aside. Her lack of any peculiar reaction offered Ling Yun some relief. At least, in front of this young maid, she didn't have to feel overly ashamed. However, this brief moment of peace was short-lived. Xiao Cui opened the brocade box, and the garments revealed within sent Ling Yun's heart plummeting once more. It was a set of gossamer silk, as thin as cicada wings, almost transparent, through which her skin could be faintly discerned. The silk was a delicate shade of pink, and atop it lay an exquisite fox mask. "Miss Ling, these are the garments specially prepared by Master Wu Xiang for the contestants," Xiao Cui's voice echoed in Ling Yun's ears. Ling Yun gazed at the silk attire, and images of herself bound, nearly naked, before the eyes of the crowd flooded her mind. Shame, anger, despair – a tangled web of emotions tightened her breathing. Cui'er picked up the fox mask from the brocade box. The material appeared incredibly light, its surface smooth as jade, possessing a distinct texture. It was a captivating silver-grey hue. The design was unique, covering only half of the face, from the bridge of the nose down to the chin, leaving the eyes exposed. But what truly chilled Ling Yun was the back of the mask. There, nestled within, was a small ball. The ball was dark, with a subtle, shadowy sheen, appearing remarkably smooth. To wear the mask, one had to take this small ball into their mouth. Ling Yun looked at the ball, and the image of it being placed in her mouth sent an unprecedented wave of humiliation surging through her. She hesitated for a moment before reluctantly parting her cherry lips. Seeing this, Cui'er, without a moment's delay, placed the small ball into Ling Yun's mouth. Upon first contact, the ball felt cool, its size just right, and its texture slightly yielding. Ling Yun could accommodate it, albeit with some effort. But at that very moment, the ball seemed to come alive, beginning to expand. Made of some unknown, special material, it started to rapidly enlarge upon contact with the saliva in her mouth. It gradually pushed open Ling Yun's mouth, pressing her small tongue firmly beneath it, rendering it immobile. It continued to swell, eventually filling her mouth completely, pressing almost to her throat, inducing a powerful sensation of suffocation. The fox mask was also held firmly in place on Ling Yun's face by the ball, fitting snugly against her skin. One had to admit, the design was ingenious, something only someone deeply versed in such matters could conceive. The cold, hard metal of the mask's edges encased her cheeks, making it impossible to struggle free or remove it. The moment the mask was donned, Ling Yun was rendered completely speechless. Her throat was blocked by the ball, her tongue pinned down, preventing any clear sound. Only faint whimpers escaped her nose. The ball lodged in her throat caused her extreme discomfort, and her breathing grew heavy.

Her eyes were tightly shut, fine beads of sweat mixing with tears on her forehead, tracing paths down her temples. She gasped for air, enduring the sharp sting from her nipples. It was an extreme pulling sensation, as if they were being ripped from her body. Yet, she didn't pause. Once accustomed to the searing pain, she moved again. She took the ropes wrapped around her thighs and back, and secured them to two other pre-prepared loops. When all this was done, she took a deep breath, as if preparing for the "ultimate restraint" to come. With difficulty, she brought her arms behind her back, threading them through several loops she had previously tied – slipknots. She knew that the moment she pulled the ropes at her wrists, these loops would instantly tighten, dividing her arms into four sections and binding them rigidly behind her. These were not loose ties; they were death knots. Once tightened, she would be unable to release herself. Normally, for self-binding, she would use slipknots for easy release. But for the "perfect effect" of this performance, she had chosen death knots. The Rabbit-Headed Woman pushed the art of extreme bondage, particularly the comprehensive restraint of her nipples, limbs, and body, to its absolute zenith. Lingyun watched from below, her heart a tempest of emotions. A slender silver chain ran from the Rabbit-Headed Woman's suspended head, directly to her nipples, pulling them upwards. Lingyun could almost feel her own clamped nipples, currently throbbing against the metal clamps, unable to break free from their steel confinement. A strange tremor rose from the depths of her soul. The Rabbit-Headed Woman glanced towards a corner of the high platform, where several burly attendants stood ready. As her gaze swept over them, the attendants nodded in understanding. Together, they yanked hard on the thick ropes they held. The ropes, guided by pulleys at the top of the platform, extended to the center of the stage, then descended to connect to the Rabbit-Headed Woman's body. Lingyun clearly saw one rope pulling her bound hair, another yanking her tightly bound arms behind her, and a third suspending her curled legs. Under the pull of the ropes, the Rabbit-Headed Woman slowly lifted off the ground. Her body rose gradually in the air, contorting herself into a "four-horse-fanning-hooves" position, her back arched to the extreme, like a drawn bow. Her enormous breasts, compressed by the ropes, were lifted high, appearing ready to burst through the thin fabric. Her nipples, previously the size of soybeans, had now swollen further and turned a deep crimson, looking luscious and inviting under the lights. Her head was pulled back by the ropes, forcing her to stare directly upwards. The thin chain connected to the gag tightened again, pulling her nipples to their limit, a painful spectacle. Lingyun could even see the pain reflected in the large, watery eyes behind the Rabbit-Head mask. Finally, at a height of about three feet from the ground, her ascent stopped. The attendants quickly secured the ropes to wooden stakes on the side, fixing her body firmly in mid-air. Suspended in mid-air, the Rabbit-Headed Woman struggled, twisting her body. Each twist caused the ropes binding her to dig deeper into her flesh. Her arms and legs, constricted by the ropes, had taken on a slightly purplish hue due to restricted blood flow, making it evident to the audience how tightly she was bound. After a while, the Rabbit-Headed Woman stopped struggling. Her body, guided by the ropes, began to rotate slowly in the air. Her intention was to allow the audience below a clear view of every part of her restrained body. From her uplifted head to her extremely stretched nipples, to her limbs tinged purple, and her suspended, arched torso. The Rabbit-Headed Woman, now hanging in the air, completed her performance of "bound beauty." Every detail of her body was accentuated by the ropes. Her purplish skin, her high-swollen breasts, her nipples stretched to their limit – all stimulated the sight and senses of everyone present. Lingyun's breathing grew more rapid. The gag in her mouth felt as if it were being compressed by an invisible force, almost suffocating her. The tight binding of her arms behind her back, and the faint stimulation on her nipples, seemed to foreshadow her own impending fate. A powerful sense of shame and helplessness washed over her once more.

The iron frame pried her lips apart, forcing her mouth wide open, her teeth clamped down on the metal ring, unable to close. Her soft little tongue was bisected by the ring, forced to curl helplessly in the metallic gap, trembling slightly. Granny Wang wrapped the leather strap around the back of her head and tied it securely. In moments, clear saliva began to slide uncontrollably from the corners of her mouth, tracing a path down her neck and dripping into the hollow of her collarbone. Her appearance was both pathetic and decadent, a stark contrast to her proud, cold eyes. Finally, Granny Wang squatted down, meticulously inspecting the iron cuffs on her thighs and the high heels. "Hmm... these cuffs are custom-made. The lock core is connected to the waist chain, so moving one part affects the whole body," she nodded. "No wonder Steward Sun said that without these locks, even ropes wouldn't be able to hold you." She reached out and nudged the steel needles on the shoe soles, sneering, "These shoes are also quite something. With every step, it's like walking on knife tips. You want to escape? You won't get three steps before the soles of your feet are pierced." She stood up, a hint of admiration in her voice, "It seems the person who fitted you with this set of torture devices was no simple individual. To think of using cuffs to bind the tendons, chains to control the pulse, needles to restrict movement, and pairing it with these custom metal heels... truly meticulous planning and ruthless execution..." She paused, her gaze suddenly turning cold. "But now that you're in the Qiu manor, you won't be able to fly or burrow your way out anymore." With that, she took out two slender iron cuffs from the ebony box. She squatted down, grabbed the Amazon's lower leg with one hand, and folded her legs from the knees towards her abdomen, curling her entire body into a ball, her buttocks pressed tightly against her heels, her thighs pressing hard against her calves. Then, she separately locked the two slender cuffs between her knee bends and her ankles, and connected the cuffs on both legs with a short chain, completely fixing her in this humiliating posture. Next, she looped the chain connecting her wrists around her waist from behind, and then fastened it to the chain at her ankles with a delicate swivel clasp. In an instant, the Amazon's limbs were completely strung together into a closed loop – her hands couldn't be raised, her legs couldn't be straightened, her waist couldn't be straightened, and her body couldn't turn. She could only lie prostrate on the ground in an extremely contorted position. Escape was out of the question; even moving slightly was incredibly difficult. Granny Wang stood up and slowly paced around her, occasionally leaning down to tug at the clasps where the chains connected, ensuring everything was secure. Afterward, she commanded, "Take her to the cleansing room." The Amazon was lifted by several maids and carried through winding corridors into a sealed cleansing chamber. Warm mist filled the room, hot water churned in copper basins, and various fragrant oils, soft brushes, and fine cloths were laid out on a stone slab. The maids skillfully hoisted her up again and gently wiped her entire body with warm, damp cloths, removing dust and sweat. Then, one of them took a small, soft-bristled brush with a copper handle, knelt down, and carefully reached under the edge of the iron cuffs on her inner thighs, scrubbing the skin stained with sweat and grime. Another maid untied the straps of the metal cloth binding her wrists, slowly unfurled her clenched fist, and used a cotton cloth soaked in warm water to meticulously clean between her fingers, under her nails, and the webbing of her hand, leaving no spot untouched. After washing, she applied a thin layer of moisturizing balm to prevent the skin from drying and cracking, then re-wrapped her hands layer by layer with the metal cloth, tying the straps tightly to ensure she still couldn't extend her fingers. It took them a full hour to finish the cleansing. The Amazon remained silent throughout, her eyes closed, allowing herself to be manipulated as if her soul had already departed her body. As the sky gradually darkened, the twilight, like ink, silently stained the window frames. Granny Wang personally entered the cleansing room, carrying a bowl of warm rice porridge. She stood before the Amazon and removed the gag from her mouth. The Amazon's jaw had long gone numb, and saliva dripped uncontrollably from the corners of her mouth. Before she could recover, Granny Wang scooped a spoonful of rice porridge with a silver spoon and forced it into her mouth. The Amazon swallowed with difficulty, a gurgling sound coming from her throat. Granny Wang only fed her five spoonfuls before stopping. "That's enough. Eating too much will make it uncomfortable to move later." Before she finished speaking, she had already inserted the silver gag back into the Amazon's mouth, wrapped the strap around the back of her head, and tied it tightly. Just then, footsteps were heard from outside the door. Steward Sun pushed the door open and entered, his gaze sweeping over the Amazon lying prone on the long table. He said in a deep voice, "Are you ready?"

He reached out and parted the sheer curtain, his breath catching in his throat. The woman before him was ethereally beautiful, almost unreal. She lay on her back, her neck long and swan-like, the hollows of her collarbones glistening with a sheen of cold sweat. Her breasts were full and high, their peaks taut and erect, peeking tantalizingly through the thin fabric. Her abdomen was flat and firm, her waist a mere handful. Her legs were forcibly bent to her chest, then spread wide and secured with ropes to the bedposts, leaving her core exposed. Her tender, pink cunt was laid bare under the candlelight, its petals slightly parted, crystalline arousal slowly seeping out, tracing wet trails down her inner thighs onto the sheets. Her phoenix eyes, even propped open by a gag and dripping with saliva, stared at him like cold stars, devoid of fear, filled only with anger, contempt, and a flicker of despair. Young Master Qiu's body jolted, his drunkenness receding significantly. He had known no less than a hundred women – courtesans, noble ladies, female bandits, even "heroines" he had personally apprehended. But those women were either crude and vulgar, or their faces contorted with rage. None could compare to the woman before him. Her skin was like congealed fat, her brows like distant mountains. Her demeanor was as cold and aloof as frost and snow, yet she was bound so humiliatingly by chains and ropes. The more unattainable she seemed, the more his blood surged. The Flying Heroine sighed inwardly. She knew this night was unavoidable. Her hands were bound into fists within metal wraps, offering no escape. Her legs were locked in a bent position, and her mouth was forced open by an iron frame. She could only watch as this man approached, his hands filled with lust, slowly reaching for her most private parts. Young Master Qiu leaned down, his hand suddenly clamping onto her left breast, while his other hand pinched the nipple of her right breast, rubbing and pulling it with force. The nipple rapidly engorged and hardened between his fingers, sending waves of pleasure she refused to acknowledge through her body. What was even more infuriating was that he lowered his head and pressed his mouth, reeking of alcohol and cheap perfume, firmly onto her gagged lips! "Mmph—" The Flying Heroine jerked her head violently, struggling to turn left and right, trying to avoid the disgusting contact. Her cheeks flushed red from her struggle, tears welling in her eyes, but she stubbornly refused to let them fall. Young Master Qiu tried several times, but she evaded him. Far from being angered, he grew more excited. "Very good… the more spirited, the more flavor," he sneered, then suddenly opened his mouth and bit down hard on her right earlobe. Intense pain shot from the base of her ear, making her body tremble violently, her muscles tensing instantly. But before the pain subsided, his wicked hand slid down her abdomen, past her pubic mound, and directly into her already slick and wet cunt. The moment his fingertips touched her labia, a glint of triumph flashed in Young Master Qiu's eyes. "Tsk…" he chuckled, "Still pretending to be chaste? Look at this down here…" With that, he thrust two fingers in forcefully. The Flying Heroine's entire body convulsed, as those two fingers churned within her cunt without any hint of tenderness.
