My sister isn't just tying herself up, she's gone too far?

The dying embers of the sun streamed through the floor-to-ceiling windows of the living room, casting a warm orange glow over the entire house. Xiao Chen, carrying his briefcase, pushed open the front door at precisely 7:40 PM. He had stayed late at the office today, his throat parched from finalizing the last project proposal. "Lulu, I'm home! What do you want for dinner tonight?" The house was silent, save for the low hum of the air conditioner. Xiao Chen slipped on his slippers, hung up his keys, and called out again, louder this time, "Xiao Lu? Are you home?" Still no response. He frowned slightly. Xiao Lu was twenty-four this year, three years his junior. She had already graduated from university and worked as a graphic designer at a design firm. She was usually lively and playful, always peeking out from her room to act cute when he returned, or deliberately hiding to startle him. But today, she was unusually quiet. "Mad at me again?" Xiao Chen shook his head helplessly. His sister had been like this since she was little. Occasionally, over trivial matters—like him forgetting to bring her a late-night snack, or accidentally remarking that her new skirt "looked a bit unflattering"—she would lock herself in her room and ignore him for hours. Girls, their emotions came and went so quickly, he was long used to it. He hung up his jacket, rolled up his shirt sleeves, and walked into the kitchen. Since his sister wasn't coming out, he'd make dinner first. Xiao Chen opened the refrigerator and took out the fresh pork ribs, broccoli, and carrots he'd bought last night. His movements were practiced. He first blanched the ribs to remove impurities, then heated the wok, added oil, and sautéed rock sugar until it caramelized. He then added the ribs and stir-fried them. A rich, savory aroma soon filled the air. He chopped ginger and garlic, drizzled in soy sauce, dark soy sauce, and cooking wine, then covered the pot and let it simmer on low heat. While cooking, Xiao Chen's mind was still occupied with work today and the meeting tomorrow. At twenty-seven, he had already established himself in his industry, earning a good income, enough to support this two-bedroom apartment. His parents had divorced early, and the siblings had relied on each other for so many years. He had long been accustomed to taking care of everything for his sister. Cooking, laundry, even occasionally accompanying her shopping for clothes, he found joy in it all. Twenty minutes later, the braised pork ribs were ready, glistening golden-brown and exuding a mouthwatering aroma. The garlic broccoli was a vibrant green, and the rice was cooked to a perfect tenderness. Xiao Chen served two bowls of rice, placed them on the dining table, wiped his hands, and walked towards his sister's room. "Lulu, dinner's ready! Braised pork ribs, your favorite. Don't be mad anymore, come out and eat." He gently knocked on the door. No response. Xiao Chen knocked twice more, his voice a little louder, "Xiao Lu? Did you hear me? The food will get cold." The room remained deathly silent. A sliver of unease began to spread in his heart. He tried the doorknob—it was locked, as expected. Xiao Chen took a deep breath and called out a few more times, even pressing his ear against the door to listen carefully, but only heard his own rapidly beating heart. "Lulu? Are you okay? Say something!" Still nothing. Xiao Chen's face changed completely. Although his sister loved to throw tantrums, she had never been unresponsive for so long, nor would she ever turn off her phone. He took out his phone and dialed her number—it was off. A bad premonition wrapped around his heart like a vine: Could she be sick? Or had she fallen? Or... had something happened? "Lulu! I'm coming in!" He stepped back half a pace and kicked hard at the door lock. "BANG!!" The wooden door let out a violent crack, the lock cylinder snapped instantly, and the door burst open. The scene inside the room immediately met his eyes, causing Xiao Chen's breath to hitch, and his entire body felt as if struck by lightning. Under the dim desk lamp, Xiao Lu was lying on her bed. She was almost completely naked, wearing only a loose white T-shirt, the hem rolled up to her waist, and nothing underneath. Her arms were bound behind her back with thick rope, her wrists crossed. The rope was wound tightly from her wrists all the way up to her upper arms, forcing her elbows together, almost touching. The knots were tied with professional precision, each one digging deeply into her snow-white skin, leaving bright red indentations. Her chest was bound in a standard Kote-kote style, the ropes looping over her shoulders, creating deep grooves above and below her breasts, pushing the pair of full breasts high up. The T-shirt was completely soaked with sweat, clinging tightly to her skin, faintly revealing two pink nipples. Even more shocking was her lower body: her legs were forced apart into an M-shape, knees bent, secured by multiple ropes to the headboard and footboard of the bed. The rope was cinched tightly around her inner thighs, and her ankles were bound together and pulled outwards. Her entire private area was completely exposed to the air. Her tender folds were slightly red and swollen from prolonged stimulation, and a large wet patch had formed on the bedsheet, mixed with sweat and clear bodily fluids. A pink gag was stuffed into her mouth, and clear saliva dripped continuously from the corners of her lips, forming long strands that fell onto her chest and the bedsheet. Her eyes were tightly shut, tear tracks visible on her long eyelashes, her cheeks flushed, her breathing shallow. She looked as if she had already fainted. Xiao Chen stood at the doorway, his mind buzzing. As a seasoned veteran of the BDSM community with nearly ten years of experience, he understood everything at a glance—this was a high-difficulty Shibari. The choice of ropes, the knot-tying techniques, and the selection of anchor points were all extremely professional, leaving virtually no room for "escape." Especially with her hands bound behind her back, rendering her unable to reach any knots; her legs forcibly spread and secured, making it impossible for her lower body to close. The consequences of a mistake in this kind of play were unimaginable. "...Lulu? This..." His Adam's apple bobbed, his voice hoarse. Shock, worry, concern, and a trace of an uncontrollable, complex emotion surged through him. He rushed to the bedside, first reaching out to check his sister's breathing—still there. Her pulse was fast, but not dangerously so. It was likely a temporary faint from prolonged binding and post-orgasmic exhaustion. Xiao Chen took a deep breath, forcing himself to calm down. He rummaged through the bedside cabinet and found the safety scissors he usually kept on hand. He carefully began cutting from the outermost ropes, whispering as he cut, "Lulu, wake up... Brother's here, don't be scared..." One by one, the ropes snapped. Xiao Lu's pale skin, which had been constricted, slowly regained its color. She let out a faint whimper, her body trembling slightly, but still did not open her eyes. Xiao Chen gently picked her up, letting her lean against his chest. One hand gently patted her back, while the other wiped the saliva from the corners of her mouth. Her body was burning hot. Beneath the sweat-soaked T-shirt, the rope marks were like red imprints, clearly etched onto her delicate skin. The inner thighs were still twitching slightly from the prolonged friction and stimulation. He looked down at the sister he had grown up with in his arms, and his throat suddenly tightened. "...You silly girl, what on earth were you playing at..." Outside the window, night had fully descended. The food on the dining table had grown cold, but in Xiao Chen's heart, an unprecedented storm had begun to brew. Xiao Chen looked at his sister, bound tightly and with tear-filled eyes, and the complex emotions in his heart gradually subsided, replaced by a gentle possessiveness. He reached out and gently wiped away the tear tracks on her face, saying in a low voice, "Let's eat first. If you starve yourself, how can we continue to play?" Xiao Lu's eyes widened, her voice trembling, "Brother... you, you haven't untied me yet... How can I eat like this?" "You don't have to eat yourself," Xiao Chen replied calmly, turning to reheat the cold dishes in the kitchen. The rich aroma of braised pork ribs filled the air again. He served a bowl of steaming rice, picked up a few pieces of flavorful ribs and bright green garlic broccoli, and brought them to the dining table. Xiao Lu was securely fastened to the chair, her hands tied behind her back to the chair back, her body completely unable to lean forward. She watched her brother approach with a spoon, and her shame reached its peak. "No... Brother, don't... This is too humiliating... I can eat myself... Please untie me first..." "No," Xiao Chen's tone was unquestionable. He pulled over a chair and sat beside her, holding the spoon in one hand and gently cupping her chin with the other. "You almost got into trouble today, so Brother needs to 'take good care of' you. Be good, open your mouth." Xiao Lu's face was so red it was almost bleeding. She shook her head desperately, but the ropes bound her so tightly she couldn't move. The chest harness rubbed against her as she struggled, sending waves of strange, tingling sensations. Her legs were spread and fixed, making it impossible to close them. The utter humiliation of being completely exposed to her brother's gaze made her tears flow again. "Wuwu... Brother... I don't want to..." Xiao Chen did not relent. He scooped up a spoonful of rice and ribs and brought it to her lips. "Open your mouth. Otherwise, I'll keep feeding you until you finish." Xiao Lu bit her lip, hesitating for a long time. Finally, under her brother's firm gaze, she shamefully opened her mouth. As the warm rice entered her mouth, she could barely taste anything, her mind filled with her current disheveled state – being fed by her brother like a helpless doll, the ropes tightening around her body, her chest pushed high, her legs shamefully spread, and saliva dripping from the corners of her mouth... With every bite, Xiao Chen would gently wipe away the grains of rice and saliva from the corners of her mouth with a tissue. His movements were patient and meticulous, as if he were caring for a precious object. Occasionally, his fingertips would deliberately brush against her lips or chin, causing Xiao Lu's body to tremble slightly. "How does it taste?" Xiao Chen asked in a low voice, feeding her another bite of broccoli. Xiao Lu blushed and replied softly, "...It's delicious... But... Brother, don't look at me like that... I'm really so embarrassed..." "If I don't look at you, how can I make sure you eat properly?" Xiao Chen smiled and picked up another piece of rib, bringing it to her lips. "Besides... you look really cute right now. Being tied so tightly by the ropes, and still obediently opening your mouth to eat." This statement almost made Xiao Lu spit out her food. Tears of shame streamed down her face, but she couldn't escape due to the restraint of the ropes, so she could only accept her brother's feeding bite by bite. The entire process lasted for more than twenty minutes. She felt like a prisoner who had completely lost her dignity, yet amidst this humiliation, she felt a strange sense of security and a hidden flutter of excitement. After the last bite, Xiao Chen carefully wiped her mouth and chin clean with a tissue, then stood up. "Dinner is finished, it's time for your punishment." Xiao Lu's heart sank. "Punishment...? Brother, what are you going to do?" Xiao Chen didn't answer. He took a black blindfold from the rope bondage box and gently placed it over her eyes, tying it securely behind her head. The world instantly plunged into darkness, and Xiao Lu's breathing immediately became rapid. "Brother... don't cover my eyes... I'm scared..." "This is your punishment," Xiao Chen's voice sounded in her ear, carrying an irresistible authority. "You secretly played with self-bondage behind my back and almost got into trouble. Today, I'll let you truly feel what it's like to be completely out of control." After speaking, he took out a roll of wide tape and placed two layers on her lips, sealing her mouth tightly. Xiao Lu could only let out muffled groans of "wuwu," and her eyes under the blindfold were already wet. Xiao Chen took two steps back and looked at his sister, who had been completely deprived of her sight and speech: her hands tied behind her back to the chair, her chest squeezed by the harness, her legs spread and fixed to the chair legs, and now blindfolded and gagged, she was like an exquisite doll waiting to be dealt with. "Stay like this for half an hour," his voice was calm. "I'll go wash the dishes. You can reflect here... and also feel the sensation of the ropes on your body." Xiao Lu shook her head desperately, letting out muffled whimpers. As her body struggled, the ropes made faint rustling sounds. In the darkness, she could only hear the sound of her brother washing dishes in the kitchen, and her own rapidly beating heart. Half an hour felt like an eternity to Xiao Lu. With every minute that passed, she clearly felt the pressure of the ropes on her skin, the aching fullness of her breasts being compressed, the shame of her legs being spread apart and unable to close, and her other senses amplified by the loss of sight. Sweat trickled down her back, mixing with her previous bodily fluids, making her feel both embarrassed and inexplicably excited. The scene of her brother feeding her earlier kept replaying in her mind, the fact that her brother also played with rope art, and his words, "Brother will help you tie from now on." Finally, the sound of water from the kitchen stopped. Footsteps gradually approached. Xiao Chen stood before her, reached out and gently stroked her taped lips, and said in a low voice, "Time's up. The punishment is over... Now, Brother will untie you." Xiao Lu's face turned even redder, and she lowered her head, whispering, "...I just... wanted to try what it feels like to be tied up by you, big brother..." Looking at her like this, Xiao Chen's gaze gradually deepened. He suddenly stood up, walked to the storage cabinet in the living room, took out a not-so-small paper bag, and placed it on the dining table. "Since I got back early today, I went to the specialty store." He opened the bag and first took out a beautifully packaged JK uniform – a white shirt, a dark blue pleated skirt, a tie, and black thigh-high socks – "I bought this for you. Try it on." Xiao Lu Next came her legs. She sat on the bed, wrapping the rope around her thighs and tying them into an M-shape. Her left leg was bent, her ankle secured to the outside of her thigh, followed by her right leg. This position made it impossible for her to bring her legs together, leaving her most intimate parts completely exposed to the air. She tried to move, confirming the ties were tight enough, then picked up the rabbit vibrator. The pink vibrator had a smooth surface, connected to a thin wire, at the end of which was a small remote. She slowly inserted it into herself, the cold sensation making her gasp, followed by a feeling of fullness, of something foreign. The vibrator nestled in the most sensitive spot within her, ready to vibrate the moment the switch was flipped. But she didn't turn it on immediately. Xiao Lu picked up the black blindfold, took a deep breath, and put it on. Darkness instantly swallowed her world, just like that night. Her breathing quickened, her fingers trembled slightly, and then she felt for the gag beside her. The rubber ball was rather large. She forced her mouth open and shoved it in. The strap buckled behind her head, the gag stretching her mouth to its limit, pressing her tongue down. All she could manage was a muffled whimper. Saliva began to pool uncontrollably, trickling down the corners of her mouth. Finally, the timed lock handcuffs. Xiao Lu fumbled until she found the handcuffs, the cold metal sending a shiver through her. She pulled her hands behind her back, bringing her wrists together, and then snapped one cuff around her left wrist. The clink of metal was sharp in the silent room. She took a deep breath and reached with her right hand to press the buttons on the timer lock. The timer lock had a small screen, but she couldn't see it with the blindfold on. She had to rely on memory to feel for the buttons—one press for hours, two for minutes, then a long press to confirm. She thought she was setting it for two hours, her fingers tapping lightly on the buttons, then she held the button down. "Beep—" a long tone sounded, and the lock engaged. She snapped her right wrist into the other cuff. "Click." The moment the handcuffs locked, Xiao Lu's heart pounded. She tried to move her hands, the metal clashing with a crisp sound, but she couldn't break free. The timer lock emitted a faint blue light in the darkness, but she couldn't see it. She was completely trapped. Xiao Lu knelt on the bed, her breasts constricted by the ropes, her legs bound in an M-shape, her hands cuffed behind her, her eyes blindfolded, her mouth gagged, and the vibrator still inside her. She tried to twist her body, but only succeeded in tightening the ropes, causing the vibrator to shift slightly within her, sending waves of tingling pleasure through her. She waited. At first, the waiting was filled with a strange excitement. She imagined what her brother would do to her if he were present, imagined how his fingers would caress her skin. Her body, rendered sensitive by the restraints, reacted to every breath as the ropes tightened across her chest, to every struggle as the ropes chafed the skin of her inner thighs. But gradually, a sense of loneliness began to creep in. In the darkness, she could only hear her own breathing and the sound of her saliva dripping. There was no gaze from her brother, no touch of his hands, no low voice commanding her in her ear. The restraint became pure and hollow, like a monologue without a response. Time stretched out, impossibly slow. Xiao Lu didn't know how long had passed; it might have only been a few minutes, but it felt like an eternity. Her knees began to ache, the M-shaped binding kept her thigh muscles taut, and her shoulders hurt from having her hands cuffed behind her. She wanted to adjust her position, only to find herself almost completely immobile. Just then, she remembered the vibrator's remote. It was on the bed, near her knees. She fumbled, bending down, reaching for the small remote with her cuffed hands. Her fingers brushed against the plastic casing. She managed to grasp it, then, by feel, pressed the power button. "Vvmmm—" The moment the vibrator began to hum inside her, Xiao Lu let out a muffled moan. The stimulation was direct and intense, pressing against the most sensitive spot within her, sending waves of electric pleasure through her. Her body tensed violently, and the M-shaped binding prevented her from closing her legs, leaving her to surrender to the spreading vibration within her. He stood up and walked towards the cabinet in the corner. Xiao Lu's heart leaped into her throat, thinking he was going to get scissors to untie her, thinking he was angry. But he just opened the cabinet door and took something out. A black gag, with a flesh-colored, realistic-looking dildo attached to the front. A dildo gag. "Since you want to put something in your mouth so badly," Xiao Chen walked back, his voice carrying a hint of coldness she didn't recognize, "then you can have this. Brother can't give you the real thing, but this... will make you think hard about what 'sibling boundaries' mean." Xiao Lu's eyes widened as she looked at the object, regretting it too late. "Brother... I..." "Open your mouth," he commanded. "This is your punishment. Who told you to make such a request?" She hesitated for a long time, then slowly opened her mouth under his unquestionable gaze. Xiao Chen slowly pushed the dildo gag into her mouth. The rubber felt cool against her skin, the tip first pressing against her tongue, then continuing to push further in. Xiao Lu's throat instinctively resisted, but the object relentlessly pushed deeper, until the tip abruptly jammed into the deepest part of her throat. "Mmmph—!!!" A violent gag reflex instantly erupted. She wanted to retch, to spit it out, but the gag and the dildo completely blocked her mouth, leaving her only with suppressed, pained "Gack—gack—" sounds. Tears immediately welled up, streaming down her cheeks. Her body convulsed violently, trying to pull back, but her brother's hand held the back of her head firmly. "Keep it in," Xiao Chen's voice came from above, with an unyielding calm. "I haven't finished tying you up yet." He fastened the strap behind the gag tightly at the back of her head, pulling it extremely taut. The dildo was securely fixed in her mouth, its tip deeply pressed against the entrance of her throat. With every swallow, her throat muscles involuntarily contracted, squeezing the foreign object and bringing on a fresh wave of nausea and suffocation. "Gack...呜呜...Gack..." Xiao Lu gagged uncontrollably, tears and saliva mixing, flowing down from the corners of her mouth and the gaps around the dildo. Her eyes were bloodshot from the irritation, her vision blurred, only able to see her brother's indistinct outline. The feeling of the foreign object deeply invading her throat wasn't pain, but an extreme, instinctual repulsion—her body wanted to expel the intruder, but it couldn't. Xiao Chen took a step back, watching her quietly. She was forced to tilt her head back, unable to lower it because the dildo was pressing against her throat. Clear liquid continuously overflowed from the corners of her mouth, dripping down her chin onto her chest, onto the bed. Every breath was accompanied by a faint sob, every swallow felt like swallowing her own dignity. "You know it's uncomfortable now?" He squatted down, meeting her gaze, and gently wiped the tears from the corners of her eyes with his finger. "This is just holding it, I haven't even started moving yet." Xiao Lu blinked desperately, looking at him with tear-filled eyes, her gaze full of pleading and regret. He didn't soften. Instead, he reached out, grasped the exposed tip of the dildo, and gently pushed it forward. "Mmmph—!!! Gack—!!!" Xiao Lu's body arched sharply, trembling violently as if electrocuted. The dildo was pushed deeper, almost stretching open her esophagus. She felt like she was about to vomit, but nothing came out, only broken, suppressed whimpers. More tears welled up, more saliva gushed from her mouth, her face turning bright red from the suffocation and intense nausea. "Brother...呜呜...Gack..." She wanted to speak, to beg for mercy, to say she was wrong, but all that came out were muffled whimpers and gagging sounds. The feeling of the foreign object deeply thrust into her throat, the complete inability to control her physiological reactions, made her feel shame and helplessness like never before. Xiao Chen watched her being tormented, his eyes deep and complex. He released his hand, allowing her a slight reprieve, but the gag remained firmly fixed in her mouth. "Do you know you were wrong?" he asked, his voice hoarse. "Between siblings, some things cannot be said, some things cannot be done. This..." He lightly tapped the dildo in her mouth. "...is your punishment. To make you remember what boundaries are." Xiao Lu nodded desperately, tears continuously streaming down her face. She truly understood. The feeling of the foreign object deep in her throat, the uncontrollable gagging, the intense physiological resistance—all made her realize that her brother was serious, that this line, he truly couldn't cross. Xiao Chen sat back on the edge of the bed, his fingers gently stroking her tear-streaked face, then sliding down her neck to her chest, pinching her nipples and kneading them. "Uncomfortable?" he asked, his tone seemingly caring, but his fingers' movements clearly provocative. "Holding this, and not being able to move, doesn't it make you want Brother to touch you even more?" Xiao Lu nodded desperately, her eyes brimming with tears. She wanted her brother to remove the gag, to spit out the foreign object from her throat, to gasp for air. "You want it, but you can't have it." Xiao Chen withdrew his hand and continued reading. "This is your punishment. For making such a request." Xiao Lu wriggled slightly beside him. Her hands tied behind her back, she couldn't use them. The dildo gag prevented her from speaking, leaving her only with muffled whimpers and occasional gagging sounds. She looked at her brother's calm profile and suddenly understood something— Her brother was truly protecting her. Not in a gentle way, but in this cruel yet effective manner, making her remember the boundaries. Twenty minutes felt like a century in this state. Xiao Lu's jaw was numb, her throat burned from the constant irritation of the foreign object, and a large patch of the bedsheet was soaked with her saliva. Her vision was blurred by tears, and her body trembled slightly from discomfort. Every swallow was a reminder—this was punishment, and she had brought it upon herself. Finally, Xiao Chen put down his book. He unbuckled the strap from her mouth and slowly withdrew the dildo gag. The moment the object retreated from her throat, Xiao Lu immediately bent over, gagging violently—"Gack—gack—". Her throat was finally free of the foreign object, but the feeling of invasion still lingered deep in her esophagus. She gasped for air, her mouth wet with a mixture of saliva and tears, her body still trembling uncontrollably. "Do you know you were wrong?" Xiao Chen asked, wiping the liquid from the corner of her mouth with his thumb and gently patting her back to help her breathe. "I know..." Xiao Lu's voice was hoarse and tearful. "From now on... I won't speak carelessly... Brother... that was too awful..." "Good girl." Xiao Chen ruffled her hair, then leaned down and placed a very light kiss on her forehead. "Siblings are siblings. We can play with restraints, but crossing the line... no. When you have a boyfriend later, then... these things can be done." Xiao Lu lowered her head, her heart suddenly aching. She leaned into her brother's embrace, feeling his warm arms around her. The discomfort of the foreign object still lingered in her throat, and tears fell again. But she still nodded softly: "Mmm... I'll listen to Brother..." Xiao Chen pulled her into his arms, untied the ropes around her wrists and upper arms, and gently massaged her sore and numb arms and shoulders. The rope marks were deeply imprinted on her skin, a shocking sight. "Are you hungry?" he asked, his voice returning to its usual gentleness. "What do you want to eat for lunch?" "...I want to eat the noodles you make, Brother," Xiao Lu said muffledly, leaning against his chest, her voice hoarse from the previous ordeal. "Okay, I'll make them for you," Xiao Chen smiled. "But when you eat, your hands will still be tied. As extra punishment for speaking out of turn earlier." "Don't move," Xiao Chen's voice came from above her. "Let me check first." His fingers, slick with shower gel foam, slid between her buttock cheeks, gently pressing the entrance that had just been explored. Xiao Lu let out a soft hum, her legs so weak she could barely stand. Xiao Chen caught her by the waist. "Does it still hurt?" he asked, his fingertips circling the entrance. "...A little..." Xiao Lu's voice was hoarse, weary from last night's cries. "But... it feels so full..." "Very good," Xiao Chen chuckled. "It hasn't closed, which means the dilation was effective. But you need to maintain it, or it will hurt again next time." He turned off the shower, lifted her out of the tub, and wrapped her in a large towel. Instead of taking her back to the bedroom, he placed her on a high stool in front of the vanity. Xiao Lu sat naked before the cool mirror, looking at her disheveled reflection – her hair messy, her eyes swollen, her lips slightly everted from wearing the gag for so long, and the lingering traces of lubricant between her buttocks. Xiao Chen took a box from a drawer and opened it. Inside lay a string of black silicone beads. They weren't ordinary spheres, but teardrop-shaped, arranged in size from fingertip to egg, seven in total. They were connected by a soft rubber cord, ending in a loop handle. "What is this..." Xiao Lu's voice trembled. "Dilation beads," Xiao Chen poured the beads into her palm. The cold touch made her flinch. "You'll wear these today. From morning till night, add them one by one. Let your body remember the feeling of being stretched, stay relaxed." Xiao Lu looked at the gradually enlarging beads. The largest one was a full ring thicker than last night's dilator. She imagined the sensation of having them all inserted into her body, her anus involuntarily contracting, sending a wave of tingling through her. "Now, the first one." Xiao Chen turned her around, positioning her to lean over the vanity, her hips raised. "Hold the mirror yourself and watch." Xiao Lu shakily picked up the small round mirror from the table, aiming it between her buttocks. In the reflection, the entrance was still slightly parted, the pink muscle quivering gently under the light. Xiao Chen pressed the first bead – the smallest, barely the size of a pinky knuckle – against the entrance. With a gentle twist, it slid inside. "Mmm..." Xiao Lu let out a soft hum, feeling the foreign object enter. But it was so small, there was almost no resistance, just a slight sensation of fullness. "Clench," Xiao Chen commanded. "Don't let it fall out." Xiao Lu contracted her muscles, feeling the bead held in place within her. The rubber cord dangled between her legs like a thin tail. Xiao Chen picked up the second bead, a ring larger than the first, and pressed it against the entrance. "Deep breath," he said. "Relax, and let me in." As the second bead was pushed in, Xiao Lu felt a distinct stretching sensation. The stinging pain of her entrance being forced open made her frown, but compared to last night, this pain was negligible. The bead slid in, resting alongside the first. The two beads formed a small bulge inside her, and she could feel the foreign object even from her abdomen. "The third one." Another ring larger. Xiao Lu's fingers gripped the edge of the vanity, her knuckles turning white. In the mirror, she could see her entrance being stretched into an unnatural shape. The pink muscle enveloped the black bead, creating a decadent contrast. As the third bead entered, she let out a long sigh. The fullness of her stretched anus made her legs weak, and she could only lean against the countertop, gasping for breath. "Can you continue?" Xiao Chen asked, his fingers stroking her buttocks. Xiao Lu bit her lip and nodded. She wanted more. She wanted that feeling of being completely filled, wanted to prove her obedience. The fourth, the fifth. The fullness inside her grew stronger. The beads formed a line, creating a firm barrier within her, pressing against her inner walls. Xiao Lu's breathing became rapid, her abdomen slightly distended. From the mirror, she could see a subtle bulge there, the outline formed by the bead string inside her. "The last two," Xiao Chen's voice was deep. "The largest ones. It might hurt, but endure it, and you'll be ready." The sixth bead was egg-sized. As it was pushed in, Xiao Lu threw her head back and let out a scream, tears welling up. The feeling of being forcibly stretched made her want to recoil, but Xiao Chen held her waist, forcing her to accept it. The bead slid in, lining up with the ones before it. The pressure inside her suddenly increased. She could feel her anus being stretched to its limit, her muscles spasming, unable to expel the bead. "Another day in this?" Her voice was weak, hoarse from recent use. Xiao Chen didn't answer. He gently placed her on the bed and walked towards the storage room. Heavy footsteps echoed on the floor, accompanied by the sound of wheels rolling. Xiao Lu struggled to turn her head, peering through the eyeholes of her latex suit to watch her brother drag out a massive black box – three times larger than the one her suit came in, with silver Chinese characters printed on it: "Vacuum Restraint Bed." "Ordered it last night," Xiao Chen said, placing the box in the center of the living room and unfastening the clasps. "Since you like being enclosed, we'll make it even more thorough." The box opened to reveal a neatly folded latex vacuum bed. Two thick layers of black latex sheeting, each 0.6 millimeters thick, with double-sealed zippers along the edges. A heavy-duty vacuum pump was attached to the side, and a metal port at the head of the bed was for connecting a breathing tube. Xiao Lu's heart skipped a beat. She had heard of these things – a person is placed inside, the air is evacuated, and the entire body is completely encased in latex, like being sealed in black amber. Not even a finger could move, and even breathing was controlled. "No... don't..." she tried to retreat, but the latex suit's constriction made her movements sluggish. "I'll die..." "You won't," Xiao Chen said, holding out a transparent breathing tube. The tube was soft, with a silicone mouthpiece. "Hold this. It's the only air you'll get after the vacuum is applied." He walked over and picked her up. The surface of her latex suit was slick with sweat, making her slip slightly in his arms. Xiao Lu could feel the tension in her brother's arm muscles, a strength that both frightened and reassured her. "Climb in yourself," he said, laying the vacuum bed flat on the floor. He unzipped one of the side zippers, a full meter and a half long. "Go in wearing your suit. Two layers of latex, and you'll know what true confinement is." Xiao Lu knelt on the floor, looking at the black opening, like a mouth waiting to devour. She painstakingly moved her knees, crawling between the two layers of latex. The internal space was narrow; she could only lie flat, her arms pinned to her sides by the latex, her legs stretched out straight. The latex rubbed against the inner walls of the vacuum bed, emitting a sticky, squeaking sound. It was dark inside, with only a sliver of light filtering through the latex sheeting from above. She could smell the heavy scent of rubber, mixed with the lingering odor of sweat and bodily fluids from her suit, creating a suffocatingly ambiguous aroma. "Breathing tube," Xiao Chen's voice came from above. A transparent, soft tube was brought to her lips. Xiao Lu opened her mouth and took the mouthpiece, securing it with her teeth. The tube extended from her mouth, connecting to the metal port at the head of the bed, like a transparent umbilical cord, the sole link to the outside world – air. "I'm going to seal it now." Xiao Chen began to pull the sealing zipper. Starting from her feet, the "zzzzip" sound circled upwards, completely enclosing her between the two layers of latex. The light gradually disappeared, until only a tiny bit of light remained at the connection of the breathing tube. Then, even that vanished, plunging her into complete darkness. The temperature inside the vacuum bed began to rise. Her sweat was trapped by her suit, and now it was trapped by the vacuum bed outside. Heat couldn't dissipate, and she felt as if she were in a steamer. "Vacuuming begins," Xiao Chen's voice became distant, muffled, as if coming from underwater. "If you can't speak, just breathe deeply. I'll watch the tube and know you're still alive." The vacuum pump started, emitting a low hum. Xiao Lu immediately felt the change – the latex sheets began to contract, not with a sudden squeeze, but like a gentle yet irresistible tide, surging from all directions simultaneously. First, her toes. Both layers of latex pressed down, fixing her toes in an extended position, unable to even curl. Then, her calves. The latex conformed, perfectly replicating the contours of her legs. She could feel her calf muscles being flawlessly etched onto the black membrane. The pressure was evenly distributed, with no dead spots, no gaps, as if being held down by countless hands at once. "Thirty percent," Xiao Chen announced. The air pressure continued to drop. The latex pressed onto her thighs, fixing her legs straight. Her tail plug, which had been able to wiggle slightly with movement, was now completely locked by the applied pressure, becoming a pillar buried deep inside her, the sensation of fullness spreading from her anus to her lower abdomen. Xiao Lu's heart skipped a beat, her fingers trembling as she answered. Xiao Chen's face appeared on the screen, his office behind him, the door closed, but sounds from outside could be faintly heard. "I watched it," he said, his voice deep, "You did well, very obedient. But..." he paused, his gaze deepening, "the last three minutes, you touched yourself in front, didn't you?" Xiao Lu's face instantly flushed, and she lowered her head, "...I just... I just touched it a little..." "A little is still a violation," Xiao Chen's voice held a smile, but was undeniably firm, "Now, punishment. Insert the dilator, the largest one, and then kneel until I get home." "Now?" Xiao Lu's voice trembled, "But... you have work..." "I'll be back at twelve," he said, "Five more hours. For these five hours, you will remain kneeling, the dilator inside you, your shirt unbuttoned, and the video on so I can see you at any time." "Now," Xiao Chen commanded, "Let me watch you insert it yourself." Xiao Lu propped up her phone, adjusting the angle so that both she and the bed were in the frame. Then she knelt down, her buttocks facing the camera, picked up the dilator, and pressed it against her entrance. "Relax," Xiao Chen's voice came from the speaker, "Let me see it go in." Xiao Lu took a deep breath and slowly applied pressure. The dilator slid in slowly, thicker and harder than her fingers, the sensation of stretching causing her to let out a long whimper. She imagined Xiao Chen watching from the other side of the screen, watching her insert the object into herself, the shame bringing tears to her eyes. The dilator was fully inserted, its base remaining outside, like a mark of shame. Xiao Lu knelt on the bed, her hips raised, her shirt hanging at her waist, her rear completely filled, unable to close. "Very good," Xiao Chen said, "Maintain this position. No moving, no climaxing, no dressing. I'll be back to check." The video call ended, and the screen went black. Xiao Lu knelt on the bed, the dilator inside her, gently swaying with her breath, bringing a constant pressure. She knew the next five hours would be a long torment, but a deeper desire made her unable to deny it – she craved this feeling of being controlled, this feeling of waiting for her brother. Outside the window, the sunlight gradually intensified, shining on her bare buttocks. Xiao Lu buried her face in the pillow and began to wait.
