Su Xiao and Lin Xin's Shibari Secret~

Su Xiao swiped through the screen, looking at more pictures. "Cousin, have you ever studied this?" Lin Xin nodded. "I've watched a lot of tutorials and practiced tying knots, but I haven't actually put it into practice yet." "Then you must really want to find a model to try it out, right?" Su Xiao looked up at him, her eyes sparkling with excitement. Lin Xin felt his throat go a little dry. "Mmm... yes. But I don't know who to ask." Su Xiao was silent for a moment, then said softly, "If... if I don't mind, would you be willing to practice on me?" Lin Xin almost thought he misheard. "What... what did you say?" "I said, I can be your model," Su Xiao repeated, a blush creeping onto her face. "But... we have to agree first, no going too far, and... we can't let Auntie and Uncle know." A surge of elation washed over Lin Xin, but he tried to remain calm. "Are you sure? This... might be a little uncomfortable." "I trust that Cousin won't hurt me," Su Xiao said earnestly. "And... I'm curious about what it feels like to be bound by ropes, it must be very special, right?" Lin Xin nodded, his mind already starting to plan their first "practice." He needed to prepare the right ropes, choose a private space, and most importantly, he had to ensure Su Xiao's safety and comfort. "So... when do we start?" Su Xiao asked, her eyes filled with anticipation. "Tomorrow afternoon," Lin Xin replied. "My parents usually go shopping, so it will just be the two of us at home then." Su Xiao nodded. "Okay, I'll wait for you tomorrow afternoon." On the way home, Lin Xin felt his steps lighten considerably. He stole a glance at Su Xiao beside him; she was looking down at her toes, a faint blush still on her cheeks. The sunlight shone on her, her white dress fluttering, making her look like an angel. But he knew that tomorrow, this angel would be willing to be bound by his ropes, becoming the first model for his artistic creation. That evening, Lin Xin took out the few rolls of hemp rope he had treasured, carefully inspecting every inch to ensure there were no rough edges or flaws. He reviewed the most basic safety knots online, silently planning the steps for tomorrow. He couldn't disappoint Su Xiao, and even less could he let her get hurt. This was not just about satisfying his own interest, but more importantly, about responding to Su Xiao's trust in him. Late into the night, Lin Xin stood by the window, gazing at the moon in the sky. He remembered when he was a child, when Su Xiao was a little girl, and they used to play together in the yard. Back then, she always followed him, looking at him, her big cousin, with adoring eyes. And now, she was willing to entrust herself completely to him, letting him bind her body with ropes. This trust made Lin Xin feel both excited and apprehensive. He secretly vowed that tomorrow, he would use the gentlest and most professional methods to let Su Xiao experience the true charm of rope art. The moonlight, like water, spilled onto this night that was about to welcome a special "practice," and also cast a mysterious halo over the journey of exploration that the two young people were about to embark on. He walked behind Su Xiao and began to tie the ropes according to the tutorial's steps. This time, his fingers were much more skilled than before, but facing his cousin so closely, he still found it difficult to remain completely calm. "Cousin, your skills have improved," Su Xiao said softly, a hint of surprise in her voice. Lin Xin smiled, "Thanks to you being such a good model." The ropes gradually formed intricate patterns on Su Xiao's body. Her upper body was tightly bound, her hands secured behind her back. Unlike last time, Lin Xin now wrapped the ropes around her chest, creating a more stable structure. "How does it feel?" Lin Xin asked, adjusting the tightness of the ropes. "Very... very tight," Su Xiao replied, her voice trembling slightly, "but... it doesn't hurt." Lin Xin nodded and continued his work. Next came the most crucial part – bending Su Xiao's body into a shrimp shape. He needed to guide the ropes from her ankles to her thighs, then connect her upper and lower body to form a compact sphere. "I... I'm going to start tying your lower body," Lin Xin warned. Su Xiao nodded and leaned forward slightly to make it easier for him. Lin Xin knelt before her and began to wrap the ropes around her thighs and calves. This position brought his face very close to her private parts, and Lin Xin found his breathing becoming difficult. "Cousin, are... are you okay?" Su Xiao looked down at him, asking with concern. "Yeah, I... I'm fine," Lin Xin replied, not daring to meet her eyes. The ropes gradually secured Su Xiao's legs together, and then Lin Xin began to bend her body backward. This process required Su Xiao's cooperation; she needed to curl herself up as much as possible. "Can you... can you bend a little more?" Lin Xin requested. Su Xiao nodded and tried her best to bend her body backward. Lin Xin took the opportunity to guide the ropes from her back to her ankles, forming a compact sphere. Now, Su Xiao's body was completely restrained and unable to move, but her breathing was not restricted. "Okay... done," Lin Xin announced, stepping back to admire his work. Su Xiao curled up on the floor, her body tightly bound by the ropes, presenting an indescribable beauty. Her body was sculpted into a perfect sphere by the ropes, and every inch of her skin felt exceptionally sensitive due to the restraint. Sunlight streamed through the curtains, casting intricate patterns of rope shadows on her skin, like a masterpiece of nature. "Cousin, I... I feel..." Su Xiao said softly, a tremor in her voice, "This time feels... very different from last time." Lin Xin nodded, "The feeling from Shibari is indeed special. It allows one to experience complete restraint, but at the same time, it can bring a special sense of security." "Security?" Su Xiao repeated, puzzled. "Yes," Lin Xin explained, "When the body is completely bound, the brain releases a substance called endorphins, which can bring feelings of pleasure and security. This is why some people are drawn to rope bondage." Su Xiao was silent for a moment, then said softly, "Indeed... I feel very safe. Even though I'm tied up and can't move, I... feel very at ease." Lin Xin understood her feelings. The art of rope bondage is not just about restraint; it is also a form of spiritual communication. Through the ropes, two people establish a special connection, a connection based on trust and understanding. "Xiaoxiao, are... are you okay?" Lin Xin asked with concern, "Is anything uncomfortable?" He felt a deep satisfaction watching Su Xiao's focused expression. Teaching her to tie ropes was far more engaging than fumbling around on his own. "So... shall we start learning to tie knots now?" Su Xiao asked expectantly. "Mhm, let's begin with the simplest knot," Lin Xin said. "This is called a 'single knot,' the most basic and essential one." Lin Xin slowed his movements, demonstrating step by step for Su Xiao. She watched his fingers intently, then picked up another coil of rope and mimicked his actions. At first, her fingers were a bit stiff, and the knots she tied were crooked and messy. "Don't rush, take your time," Lin Xin encouraged her. "Tying knots requires patience, just like learning to write. It takes time." Su Xiao nodded and continued practicing. Gradually, her fingers became more nimble, and the knots she tied grew neater. Lin Xin's heart swelled with pride as he observed her concentration. "Cousin, look, I did it!" Su Xiao exclaimed, excitedly holding up the knot she had tied, a look of accomplishment on her face. "That's wonderful," Lin Xin smiled and nodded. "Next, we'll learn the 'double knot.' This is an upgraded version of the single knot, stronger and more aesthetically pleasing." He began teaching the new knot, and Su Xiao diligently followed along. Sunlight streamed through the window, and the ropes wound around their hands, creating various beautiful patterns. In this moment, they weren't just cousins; they were partners exploring an art form together. "Xiao Xiao, you're learning so quickly," Lin Xin praised her sincerely. "Cousin teaches very well," Su Xiao replied modestly, her eyes sparkling with happiness. "And... I find tying knots quite interesting, like... like creating something." Lin Xin nodded. "Indeed, knots themselves are an art. Each knot has its own structure and beauty. A good knot isn't just strong; it's also visually appealing." They practiced for a while longer, until Su Xiao had learned all the basic knots. Lin Xin glanced at the time. "There's still a little while left. Shall we... try some new tying methods?" Su Xiao's eyes lit up again. "Okay! What kind of method?" "There's a method called 'Rhombus Chest Harness'," Lin Xin explained. "It primarily binds the upper body, accentuating the chest lines beautifully, and... it's not too tight, making it suitable for longer wear." "Rhombus Chest Harness?" Su Xiao repeated. "It sounds quite elegant." Lin Xin took out his phone and found some reference images to show her. The Rhombus Chest Harness involved creating a diamond pattern across the chest, appearing more intricate than the previous 'high-hands tie' but also more visually appealing. "Cousin, can you tie it?" Su Xiao asked curiously. Lin Xin nodded. "I... I'll try. However, it might be more complex than the previous methods and take more time." "It's fine," Su Xiao said without hesitation. "I trust you, Cousin." Lin Xin's heart warmed. "Then... let's begin." Su Xiao slipped off her pajama top, wearing only a thin white camisole. This simple action made Lin Xin's heart race. He forced himself to focus on the rope, to avoid looking at his cousin's slowly revealed curves. "Let's start with the basics," Lin Xin said, his voice a little tight. "We'll create a foundational structure across your chest first." He stood before Su Xiao and began wrapping the rope around her chest. This time, his fingers were more practiced than before, but being this close to his cousin still made him a little nervous. "Cousin, your technique has really improved," Su Xiao murmured softly, a hint of surprise in her voice. Su Xiao stood in the center of the room, her phone in hand, displaying a standard "Four-Horse Harness" image. In the picture, the model was lying face down, her legs tightly bent, ankles crossed behind her back, her entire lower body secured by ropes, presenting a posture of extreme vulnerability and complete immobility. "It's that... lying down, legs bent behind the back, right?" She looked up at Lin Xin, her eyes gleaming with an almost fanatical anticipation. "Last time you tied me in a high-and-tight knot, I wanted to try this. I heard... this is one of the most despairing positions." Lin Xin looked at the picture, then at Su Xiao. He understood that what she desired was not simple restraint, but a complete "surrender." In the Four-Horse Harness, the bound person not only couldn't move their legs but couldn't even roll over, feeling pinned to the bed, passively accepting everything. "This... is indeed more difficult than a straight-arm bind," Lin Xin walked to the drawer and took out the roll of his most cherished reddish-brown hemp rope, along with a slightly thinner cotton rope for securing. "And once it's tied, unless I untie it, you won't even be able to turn over. Are you sure you want to try?" "I'm sure," Su Xiao nodded without hesitation. "Cousin, I trust you." Lin Xin took a deep breath and nodded. He had Su Xiao lie face down on the bed, her arms resting naturally at her sides. "Ready?" he asked softly. "Mmm," Su Xiao's voice trembled slightly, but her gaze was firm. Lin Xin knelt behind her and began his work. He first used the hemp rope to bring Su Xiao's ankles together, then began to wrap. He didn't simply bind them but employed the standard Four-Horse Harness technique: bending her legs at the knees, bringing them up, crossing her calves, and pressing her ankles tightly together behind her back. "It might be a bit tight, bear with it," Lin Xin said as he pulled the rope taut. Su Xiao's body trembled slightly. As her legs were forcibly bent and her ankles crossed behind her back, an intense pressure instantly washed over her. Her hip joints were fully opened, her lower back forced to arch backward, presenting a posture of extreme contortion. "How does it feel?" Lin Xin asked as he continued to wrap. "So... so tight..." Su Xiao's voice was shaky, but she didn't flinch. "But... it feels so unique." Lin Xin didn't stop. He began wrapping the rope from her ankles, circling upwards past her calves, knees, and thighs, finally encasing her legs together tightly, like wrapping a gift. He deliberately tied a secure knot at her ankles to ensure they wouldn't loosen. "Next, securing the upper body," Lin Xin picked up the other roll of rope. Starting from her waist, he wrapped it over her shoulders and back, forming an 'X' shape. This structure not only secured her upper body but also left her back completely exposed. "Done," Lin Xin announced softly, stepping back to admire his work. Su Xiao lay there, her legs bent high, ankles crossed behind her back, her entire body like a taut bow. Her upper body was secured by ropes, rendering her unable to turn over or even adjust her position. She could only lie there, like an exquisitely bound work of art. "I... I can't move," Su Xiao's voice held a hint of panic, but more so, a strange excitement. "I can't even... even roll over." "This is the charm of the Four-Horse Harness," Lin Xin walked in front of her, crouching down to look at the curves of her body outlined by the ropes. "Your legs no longer belong to you; they are merely extensions of the ropes. You can only lie here and accept everything." Su Xiao could feel that her body was completely immobilized. She tried to move, but the ropes were like cast iron, unyielding. She could even feel that if she exerted even a little force, her entire body would fall due to loss of balance. "Cousin..." she whispered, her voice laced with a touch of helplessness. "I... I'm a little scared." "Don't be afraid," Lin Xin reached out and gently caressed her cheek. "I'm here. I'll be with you." Su Xiao nodded, closed her eyes, and began to feel. Time ticked by, minute by minute. At first, the intense pressure made her uncomfortable. Her lower back began to ache, and her legs grew numb from maintaining the same position for so long. But gradually, she began to adapt to the sensation. She discovered that when her body was completely immobilized, her senses became even sharper. She could feel every touch of the ropes pressing against her skin, the rhythm of her own heartbeat, and even the flow of air in the room. "Cousin..." she whispered softly. "I... I can feel... my legs feel like... they don't belong to me anymore." "Yes," Lin Xin's voice was calm. "This is the magic of the Four-Horse Harness. When you completely surrender resistance and accept the restraint, you'll find yourself... becoming very light." Su Xiao remained silent. She closed her eyes, letting the peculiar sense of peace envelop her. Just then, Lin Xin stood up and walked back to the drawer. But this time, he didn't take out a silk scarf. Instead, he took out a small box wrapped in black velvet. Su Xiao heard his approaching footsteps again and curiously opened her eyes, wanting to see what new trick he had up his sleeve. "We... we're out?" Her voice was hoarse. "Mmm, we're out." Lin Xin drove, reaching out to gently stroke her hair. "My little hero, you were so brave just now." Su Xiao's face flushed crimson. She recalled the madness in the library, the librarian, the near exposure, and a wave of lingering fear washed over her, but more than that, a thrilling, secret excitement. She shifted her hands, cuffed behind her back. The cold metal was a stark reminder of her restraint. "Cousin... can you... can you take these off now?" she asked softly. Lin Xin glanced at her, a knowing smile playing on his lips. "It wouldn't be as fun if I did," he said. He drove to a secluded spot and parked. Then, he turned to face her. "Show me your hands," he commanded. Su Xiao obediently brought her cuffed hands from behind her to the front. Lin Xin produced a key and unlocked the handcuffs. Just as Su Xiao thought she was finally free, Lin Xin clicked them shut again. This time, her hands were cuffed in front of her. "Pull down your sleeves to cover them," Lin Xin instructed, gesturing to the wide sleeves of her cardigan. Su Xiao blinked, then understood. She pulled down the long sleeves, completely concealing the gleaming handcuffs. From the outside, she looked like a cool girl who favored oversized clothing, no one suspecting her hands were bound by cold metal. This pretense of normalcy, of being shackled in plain sight, gave her an unprecedented, exhilarating sense of both safety and thrill. "Alright, my little prisoner," Lin Xin restarted the car. "Now, we're going on a date." Their first stop was a corner milk tea shop. The place buzzed with chatter, the air thick with sweet aromas and the laughter of young people. Lin Xin had her find a seat by the window while he headed to the counter. "What do you want?" he asked, looking back. "Strawberry milkshake, please," Su Xiao whispered, a hint of post-escape timidity in her voice. Lin Xin ordered two drinks and returned with a tray. He placed a pink, fragrant strawberry milkshake in front of Su Xiao. "Drink up," he said. Su Xiao looked at the tempting milkshake, then at her cuffed hands, half-hidden by her sleeves. How was she supposed to pick it up? She tried to cup the glass with her bound hands, but the handcuffs made her movements clumsy and awkward, the metal digging into her wrists. As she fumbled, her composure about to crack, a young server approached, a standard, friendly smile on her face. "Miss, can I help you?" Su Xiao's heart leaped into her throat! Like a cat with its tail stepped on, she instinctively yanked her hands back into her wide sleeves, her face a mask of panic. Lin Xin, however, remained unfazed. He smiled, a bright, disarming smile, and casually walked over. He picked up the milkshake, expertly inserted a straw, and brought it to Su Xiao's lips. "My girlfriend is a bit shy, sorry to trouble you," he said to the server, his tone filled with affectionate indulgence. "Cousin... what... what are you doing?" Her voice trembled noticeably. "No... don't use that..." Lin Xin remained silent. He picked up the ball gag and walked towards her. His eyes were calm, but beneath the surface, an unyielding resolve lay hidden. "Xiaoxiao, do you remember our first time?" he asked softly. "You said that no matter how far we explored, we had to stay true to our original intention—this is art, nothing else." Su Xiao stared at him blankly, not understanding why he suddenly brought this up. "But art also requires ultimate experience," Lin Xin's voice deepened, becoming magnetic. "A silk scarf is gentle, it's a compromise. But this... this is true 'deprivation.' It will make you understand what complete, voiceless, total submission is." He knelt down and brought the cold ball gag to her lips. "No... cousin... I don't want it..." Su Xiao shook her head desperately, her lips sealed tight, like a startled fawn. Lin Xin didn't force her. He simply gently cupped her chin with his other hand. His grip wasn't strong, but it made her unable to struggle. "Xiaoxiao, open your mouth." His voice was still calm, but with a hint of command. "Mmm... no..." Su Xiao whimpered, tears welling up in her eyes. Lin Xin looked at her, on the verge of tears, a flicker of reluctance crossing his heart. But he knew he had to do this. This was a necessary stop on the path they were exploring together. He said no more. Instead, with his thumb, he gently, yet irresistibly, pried open her lips. The moment she opened her mouth, Lin Xin unhesitatingly thrust the silicone ball gag inside. "Mmmph—!!" A muffled groan, suppressed by force, filled with terror and humiliation, erupted from Su Xiao's throat. The ball gag was larger than she had imagined, forcibly stretching her jaw open, leaving her mouth in a humiliating, half-open state. Her tongue was pinned beneath it, immobile. Saliva began to secrete uncontrollably, trickling down the corners of her mouth. The sensation was awful. A hundred times worse than the silk scarf. The scarf was a gentle occlusion, but this ball gag was a cold invasion. It stripped her of her right to speak, and even made swallowing difficult. Lin Xin ignored her muffled protests. He skillfully parted the hair at the back of her head, wrapped the leather strap around her cheeks, and fastened it behind her head, then pulled it tight. With a "click," the buckle on the strap locked into place. Now, her mouth was completely, utterly sealed. "Mmm... mmmph..." Su Xiao's tears finally broke free, streaming down her cheeks and soaking into the bedsheets. She struggled desperately, but the hobble-tied restraints rendered even the slightest resistance impossible. She could only lie there, like a sacrificial offering, weeping helplessly, emitting meaningless cries. Lin Xin watched her quietly, observing her transition from terror to struggle, and then to a slow calm. He knew she needed time to accept this new, more brutal experience. He remained silent, not touching her, simply giving her space. A few minutes later, Su Xiao's struggles gradually ceased. She no longer whimpered, merely lying there, her body trembling slightly from suppressed sobs. She seemed to understand that resistance was futile. "You tortured me with this for half the day last time," she dangled the feather, "Now, it's my turn." She didn't hold back, using the tip of the feather to trace directly towards Lin Xin's most ticklish spot on his waist. "Hiss!" Lin Xin's whole body jolted as if electrocuted. "What? Cousin, you're ticklish too?" Su Xiao's voice was laced with triumphant laughter. She began her "revenge." The feather, like a nimble little snake, slithered across his back, sides, ribs, armpits... every spot Lin Xin was known to be ticklish, it darted back and forth. "No... no... Xiaoxiao... stop!" Lin Xin started to beg. Bound as he was, he had nowhere to escape, forced to endure the torment of the infernal feather. His breaths came in ragged gasps, his body shaking uncontrollably with laughter, like a sieve. "Begging now? Too late!" Su Xiao was having a blast. She even used both hands, wielding two feathers, to attack two of his ticklish spots simultaneously. "Hahahaha... stop... stop! I can't take it anymore! Hahahaha..." Lin Xin completely broke. He collapsed onto the bed, tears streaming down his face from laughter, only able to plead in broken gasps. Seeing his pathetic state, Su Xiao felt a surge of satisfaction. But then, looking at his flushed face, hearing his tearful pleas, her heart softened. She stopped her movements. The room fell silent, leaving only Lin Xin's heavy, panting breaths. "Do you... dare to do it again?" Su Xiao deliberately put on a fierce expression. "No... no more... my dear aunt... please spare me..." Lin Xin said weakly. Su Xiao looked at him, at the sweat beading on his forehead from laughter, at his eyes, glistening with mirth. Suddenly, a thought sparked within her. She lowered her head and, on his still smiling, slightly parted lips, she swiftly, lightly, planted a kiss. Lin Xin's laughter died instantly. He froze, utterly stunned. And Su Xiao, the moment the kiss landed, seemed to have used up all her courage. Her face flushed crimson, like an overripe tomato. She fumbled with the ropes binding him, her fingers, trembling with nervousness and panic, fumbling the knots several times. "I... I'll untie you! You... you get up quickly!" she stammered, unable to meet Lin Xin's gaze. As the last rope slipped from Lin Xin's arm, he was free. He didn't get up immediately. Instead, he slowly rolled over, lying there, quietly watching his cousin, who was still fumbling, her face burning with embarrassment. "Xiaoxiao." He called her softly. "What!" Su Xiao buried her head lower, like an ostrich. Lin Xin said nothing. He reached out, gently lifting her chin, forcing her to look at him. He gazed into her flustered, shy, yet expectant eyes, then, slowly, slowly, he leaned in and kissed her lips. This kiss was nothing like the fleeting, stolen peck from before. It was gentle, yet possessive; tender, yet filled with emotion. Su Xiao was completely lost. She forgot to struggle, forgot her shyness, and could only let Lin Xin kiss her. He didn't start with her arms, but with her ankles. He wrapped the pink rope around her left ankle twice, then pulled it tight, tying a neat knot. Next, he brought the rope upwards, around her calf, tying another knot below her knee, and continued upwards until her entire left leg, from ankle to thigh, was securely and evenly bound in pink rope. Su Xiao could feel that the rope was neither too tight nor too loose, just enough to bind her leg without causing any pain. Lin Xin used the same method to secure her right leg. Now, both her legs were encased in pink rope, looking like a pair of artworks. "Bring your legs together," Lin Xin commanded. Su Xiao obediently brought her legs together. Lin Xin picked up another roll of rope and began to tie her legs together. Starting from her ankles, one loop, two loops, three loops… the rope, like vines, bound her legs tightly together, making it impossible for her to separate them. "Alright, legs are done," Lin Xin said softly, then asked Su Xiao to turn over and lie flat on the bed. Next, it was her arms. Lin Xin still used the rear-hand tie, but this time, his technique was more intricate and secure. He wove the pink rope back and forth between her wrists, forearms, elbows, and upper arms, creating a dense, yet beautiful, net of rope. Finally, her arms were pulled high and secured to the headboard. Su Xiao now looked like a butterfly caught in a pink spiderweb, completely immobilized. "Cousin…" she whispered, a barely perceptible tremor in her voice. "What is it?" Lin Xin asked casually, admiring his handiwork. "I… I have one more thing I need your help with," Su Xiao's face flushed deeper. "On the table in my room, there's a pink button… could you… could you get it for me?" "Button?" Lin Xin paused. "What button?" "You'll know when you go," Su Xiao's voice grew even softer. "And… before you get the button, could you… could you gag me first, like last time?" Though Lin Xin found it strange, he nodded. He took out a silk scarf and gently, tenderly, stuffed it into Su Xiao's mouth, muffling all her words. "Mmm…" Su Xiao hummed with satisfaction. Lin Xin stood up and walked towards Su Xiao's room. Su Xiao's room was as clean and warm as his own. His eyes immediately fell upon the object on her desk. It was a pink, palm-sized remote control, with a single round button that glowed with an alluring light. Lin Xin's mind went "buzz," as if struck by something heavy. He instantly understood what it was. He froze there, his blood seeming to turn to ice. He slowly, disbelievingly, turned his head to look in the direction of his own room. That pink button exploded in his mind like a bombshell. He remembered Su Xiao's unusual behavior just now, her trembling voice, her evasive eyes… and why she insisted on being gagged first? Lin Xin held the girl in his arms, sleeping soundly, the one he both loved and hated, yet he felt no sleepiness at all. His eyes were open, gazing at the large moon hanging above the treetops outside the window. His heart was as clear as a mirror; their lives, starting tonight, had irrevocably veered onto a forbidden and sweet diverging path. And he, willingly. He held her like this for a long, long time, until his arms began to feel numb. Only then did he prepare to gently set her down and let her lie comfortably. The moment he moved, the person in his arms suddenly let out a soft moan, her arms instinctively tightening, holding him even closer. "Don't..." she murmured in her sleep, her voice soft and slurred, "Don't untie..." Lin Xin's movement stopped. "Cousin..." she whispered again, as if in a dream, her voice laced with a hint of pleading and longing, "I... I want... to try... sleeping tied up..." Lin Xin's heart felt as if it had been struck by something heavy. Sleeping tied up? This idea was more insane, more daring than all their previous games. It meant she was willing to surrender everything, without reservation, twenty-four hours a day, to him. Even in her most defenseless sleep, she wanted to be within his restraints. What immense trust was this? And what profound... surrender? Lin Xin felt his breathing become difficult. He looked at her innocent and pure sleeping face, then thought of the daring request she had just uttered. He felt as if he were standing on the edge of a precipice. One step forward was an abyss from which there was no return. But to step back, he couldn't bear it. He hesitated. Su Xiao seemed to sense his hesitation. She nuzzled her face into his chest, her voice almost like a spoiled child's, thick with a nasal tone, repeating, "Okay, Cousin... just... just tonight..." Lin Xin felt his heart melt completely in that instant. What ethics, what morals, what future – they all could go to hell the moment she said those words. What he wanted was her. Her willing, unreserved, complete submission. "Okay," he heard his own voice, hoarse yet incredibly firm, utter the word. Gently, he laid her down on the bed, and then, he picked up the roll of pink rope again. This time, he didn't choose a complex binding method. He simply used the most tender yet most secure way, bringing her hands together in front of her, and then using the rope to gently secure her hands to her body, fixed to the headboard. This way, she could turn over, adjust her sleeping position, but her hands would never be able to break free. After finishing, he looked at her. She seemed to be completely asleep, a satisfied, sweet smile on her face. Lin Xin leaned down and gently placed a kiss on her forehead. "Goodnight, my... Xiaoxiao," he whispered softly in her ear, in a voice only they could hear. Then, he pulled the blanket over her. He himself moved a chair and sat by the bedside, quietly guarding this unique treasure, his own, wrapped in pink ropes and sweet dreams. Su Xiao’s face, and opened the tightly sealed box. “What… what did you buy again?” Su Xiao looked up from behind her book, her eyes filled with curiosity and a hint of undisguised anticipation. Lin Xin didn’t speak. He simply took out the black, glossy leather single glove from the box. Su Xiao’s eyes instantly lit up. She put down her book and leaned closer, her fingers tracing the cold, smooth leather, feeling its powerful texture. “This… looks even more… more intense than the last one,” she whispered, her voice tinged with excitement. “Want to try it on?” Lin Xin raised an eyebrow. Su Xiao nodded vigorously. Lin Xin asked her to extend her hands, and then, he slowly, deliberately, slid the black single glove onto her fingers, inch by inch. As her hands were fully encased and forced together, an unprecedented feeling of being utterly “armed” sent goosebumps all over her body. Lin Xin produced a small brass padlock and, with a click, secured the metal ring at the glove’s wrist. “There,” he said, shaking the key in his hand. “Now, your hands are completely mine. Unless I unlock them myself, you can’t do anything.” Su Xiao tried to move her fingers, but her hands felt as if they were filled with lead. She could only move her hands as a whole; not a single finger could be separated. This complete helplessness made her feel dizzy. “Cousin…” she looked up at him, her watery eyes filled with dependence and pleading, “I… I like this.” “I know,” Lin Xin smiled. Then, he took out a second item from the box – the pink, butterfly-shaped wearable vibrator. Su Xiao’s face instantly flushed crimson. She recognized it immediately. “This… I… I’ll… later tonight…” she said shyly, reaching for it to hide it away. “No,” Lin Xin stopped her. “Now. Right now, put it on.” “N-now?” Su Xiao’s eyes widened. “Why?” “Because,” Lin Xin leaned in close to her ear and whispered in a seductive, devilish tone, “I want you to wear it when we go to see a movie.” Su Xiao’s body stiffened. She looked at Lin Xin in disbelief. “Are you… are you crazy?! Now? Wearing this… out?” “Yes,” Lin Xin’s face held an undeniable, wild smile. “Just like this, in this white dress, with this glove, and… with this little thing hidden inside you. Let’s go see a movie, shall we?” Su Xiao’s mind went blank. She imagined the scene: in a dimly lit cinema, surrounded by strangers, he could, at any moment, use a remote control to make her… The thought was too wild, too thrilling, and too… shameful. Her body resisted, but deep within, the demon of submission roared, craving it. She looked into Lin Xin’s expectant, challenging eyes and knew, once again, she couldn’t refuse. She closed her eyes, as if accepting her fate, and took the pink, sinfully tempting butterfly from Lin Xin’s hand. “To your room… I… I’ll change…” her voice was barely a whisper. Lin Xin's heart plummeted. He felt things spiraling in a direction he couldn't control. "Xiaoxiao... no... stop playing, let me go..." His voice, hoarse from recent passion and current fear, cracked. "Shh..." Su Xiao merely placed a finger on his lips, still stuffed with the sock he'd worn all day. Then, she began to work on the knots binding his wrists behind him. As the ropes restraining his hands loosened, a flicker of hope ignited within Lin Xin. He thought she was going to let him go. But Su Xiao's next actions plunged him into the abyss of despair. She didn't let him turn over. Instead, she pushed him face down onto the bed. Then, with the handcuffs she hadn't yet put down, she clicked them shut, re-restraining his hands behind his back. Next, she began a new kind of bondage, with a professional and ferocious technique he'd never witnessed before. She first bent his legs, pulling his ankles towards his thighs, then used rope to firmly bind his calves and thighs together, forming a perfect "bent leg restraint." She then crossed his legs in front of him, ankles pressed tightly together behind him, and used rope to connect his legs to his hands, which were cuffed behind his back. This was an incredibly cruel and secure "shime-wa" bondage. Lin Xin's body was utterly, completely folded into an immobile ball of flesh. His hands were cuffed behind him, his legs crossed and secured behind him, his entire being like a bound, sacrificial lamb, filled with helplessness and humiliation. "Xiaoxiao... you... you're crazy?! Let me go!" he began to struggle frantically, but Su Xiao's newly learned Japanese bondage techniques, combined with the inherent restraint of the shime-wa, made all his resistance appear pathetically weak. The ropes, like searing hot iron chains, dug deep into his flesh, rendering him immobile. "I'm crazy?" Su Xiao laughed, her laughter crisp and exceptionally cruel in the silent room. "I'm helping you, Master. Helping you experience the feeling of being left, of helplessness, that you made me experience last time." She paused, then added in a voice filled with malicious sweetness, "However, I won't leave you here all night. I'm just... going out for a bit. You... enjoy yourself here for now." With that, she stood up, dressed herself, and then, without a backward glance, walked out of the room, even closing the door behind her. "Click." The sound of the lock turning was like a death knell in Lin Xin's heart. She really... left? Leaving him alone, bound in this humiliating position, for the entire night? No... it couldn't be... she was just scaring him... she'd be back soon... Lin Xin desperately tried to reassure himself, but the blindfold, the gag, and his completely restrained body felt like an invisible hand gripping his heart, plunging him into unprecedented, overwhelming panic. He began to struggle. He used all his strength, trying to break free from the damned ropes. His muscles tensed with exertion, veins bulging on his forehead and neck. But the ropes seemed to have grown onto him, unmoving. The more he struggled, the tighter they dug in, causing him unbearable pain. He gave up. After struggling for only a few minutes, he completely surrendered. He collapsed onto the bed like a shrimp drained of all its strength, gasping for air. Sweat had already soaked the sheets beneath him. Despair, like a tidal wave, drowned him. Lin Xin stood before the floor-to-ceiling mirror in the bedroom, holding the all-black K9 bondage suit he'd seen in the pictures. It was an exquisitely crafted piece, a fusion of leather and PVC with an industrial aesthetic, adorned with silver metal buckles, chains, and intricate strapping. "Xiaoxiao, come here," Lin Xin's voice was deep and magnetic, laced with an undeniable command. Su Xiao, clutching the black bag, her cheeks flushed to the point of bleeding, lowered her head. Like a startled rabbit, she shuffled step by step towards Lin Xin. "Put it on," Lin Xin handed her the bag, his gaze burning into her. "But remember, this outfit, only I can help you put it on, and only I can help you take it off. You yourself cannot unlock it." Su Xiao's face grew even redder. She bit her lip, then finally nodded. She turned and walked into the bathroom, locking the door. When she emerged again, she had shed all her clothes, clad only in the black, form-fitting bondage suit that encased her body. Lin Xin watched her retreating back, his eyes deepening. He walked forward and embraced her from behind. "Don't move," he murmured. He began to fasten the remaining pieces onto her. First, the black collar with its metal tag. He carefully placed it around her fair neck, then with a "click," he secured the lock. The "K9" inscription on the metal tag glinted coldly under the light. "This is your new name," Lin Xin's voice whispered in her ear. "From now on, you are my little dog." Su Xiao's body trembled slightly, but she offered no resistance. Next, Lin Xin picked up the black gloves with their metal finger caps. He brought Su Xiao's hands together, then slowly, he slid the gloves onto them. As the glove clasps were fastened, Su Xiao's fingers were completely immobilized in a flexed, ungraspable position. "Now," Lin Xin picked up the crucial headpiece with its two cute ears, and walked in front of her. "Lift your head." Su Xiao obediently raised her head. Lin Xin slowly, gently, placed the headpiece over her head. "Click." The moment the buckle at the back of the headpiece fastened, Su Xiao's vision was completely obscured. She could only see a small, blurry patch of light ahead, and all her hearing was filtered into a dull, distant hum by the padding inside the headpiece. "There," Lin Xin looked with satisfaction at the fully encased "little dog" before him. "Now, crawl over." Su Xiao felt her body become unusually heavy. On all fours, she clumsily, somewhat unsteadily, crawled towards Lin Xin on the floor. Lin Xin sat on the sofa, watching the "little dog" completely wrapped in black leather crawl towards him, a playful smile curving his lips. "Come here," he patted the floor beside his feet. "Sit here." Su Xiao obediently crawled over and curled up at his feet, like a real, loyal little dog. "Good girl," Lin Xin reached out and gently stroked her headpiece, the gesture as tender as if he were petting a real pet. "Now," Lin Xin picked up the remote control and pressed a button. "I'm going to watch a movie. You just stay here, with me." Su Xiao lay at his feet, not daring to move. Her field of vision was low, only able to see his casually placed slippers and the cold floor covered with soft carpet. The movie began, a slow-paced art film.
