Young Master's Bondage Instructor

The entire class rose in a rustle, shouting in unison, "Good morning, teacher!" before settling back down. As Lin Yi sat, he stole a glance at Li Yuanyuan's legs – the stockings shimmered faintly under the sunlight, making her legs appear even longer and straighter. He quickly averted his gaze, his ears once again flushing hot. "Before we begin today's lesson, I have a special announcement for everyone," Li Yuanyuan swept her gaze across the class, her expression a little peculiar, as if she herself found what she was about to say hard to believe. "The school has decided on a temporary basis to add a special practical class each week, as part of our comprehensive quality education." The students exchanged bewildered glances, wondering what kind of practical class would warrant such a solemn announcement from their homeroom teacher. Li Yuanyuan paused, seemingly choosing her words carefully, before continuing, "The name of this course is... Shibari Art Practice Class." The classroom fell silent for two seconds, then erupted into chaos. "Shibari? What shibari?" "What the heck? Did I hear that right?" "Bondage???" The boys reacted first, their eyes nearly popping out of their sockets as they chattered excitedly, their voices loud enough to threaten the ceiling. The girls, on the other hand, looked utterly baffled, exchanging incredulous glances. A few of the more bashful ones were already blushing. "Quiet! Quiet!" Li Yuanyuan rapped on the podium, her own expression betraying a hint of unease. "This is an official school notice, so please don't make a fuss. The purpose of this course is to cultivate students' practical skills and spirit of cooperation. It's a normal part of the curriculum, and I hope everyone will take it seriously." Even as she said it, her own face was flushing, clearly finding the explanation unconvincing. But she was a responsible teacher, and with the school's notice issued, she had to comply. "The school has specifically hired professional shibari instructors to teach you. The first and second periods this morning are the first practical session, held in the multi-purpose hall of the gymnasium." Li Yuanyuan took a deep breath here, the blush on her face deepening. "As demonstrations will be necessary during the lesson, I... I will be assisting the instructor as a demonstrator." This statement ignited an even more fervent reaction from the students. "Holy shit! Teacher Li is going to be the assistant?" "You mean Teacher Li is going to be tied up?!" "Am I still dreaming?" Lin Yi sat frozen in his seat, utterly stunned. His mouth hung open, his mind buzzing. The half-joking thought from last night and Li Yuanyuan's words now were replaying in his head, making it difficult to distinguish between dream and reality. He pinched his thigh hard, the pain almost making him cry out – it wasn't a dream. Every word Li Yuanyuan spoke aligned perfectly with the absurd thoughts he'd mumbled last night – a bondage class, boys tying up girls, his chance to touch Shen Yue... He had said "tomorrow," and today was "tomorrow." How was this possible? Lin Yi's heart pounded, his palms slick with sweat, his mind a chaotic mess. He tried to convince himself it was a coincidence, that it had to be. How could such a ridiculous thing be realized by a single utterance from him? He wasn't a god, not a magician. He was just an ordinary high school student who got nervous talking to girls. How could he possibly have this kind of power? But... this coincidence was too uncanny. It was almost sinister. While he was lost in his thoughts, Li Yuanyuan signaled for the class to rise and form a line to head to the gymnasium's multi-purpose hall. The boys were practically vibrating with excitement, their chatter in the hallway like a troop of hyperactive monkeys. The girls, on the other hand, were flushed, linking arms, whispering amongst themselves. Some were cursing the school as perverted, others were worried about how they'd be tied, and a few, despite their protests of disgust, harbored a barely perceptible flicker of anticipation in their eyes. The woman appeared to be in her late twenties, younger than Li Yuanyuan, but with a completely different aura. She was dressed in a black, form-fitting outfit made of what seemed like a stretchy material, accentuating every curve of her body – her full breasts, slender waist, and rounded hips were on full display. Her features were mature and alluring, with narrow eyes, full lips, and a slight upturn at the corners of her mouth, giving her a look that was both dangerous and captivating, as if she were perpetually on the verge of a smile. What was most striking were the black, thigh-high boots she wore, with slender, high heels that made her appear even taller and more statuesque. She stood there like a drawn sword, sharp and deadly. "Hello everyone, my name is Qin Yun, and I am your instructor for this practical class on the art of Shibari," she announced. Her voice was low and husky, carrying an indescribable laziness and allure. "This is Teacher Li, your homeroom teacher, who will be assisting me today as my teaching assistant for the demonstration." Li Yuanyuan stood beside her, her expression striving for the composure and seriousness befitting a homeroom teacher. However, a closer look revealed her fingers trembling slightly and her breathing noticeably quicker than usual. The rise and fall of her chest was more pronounced than normal. "Before we begin, I must first emphasize classroom discipline," Qin Yun said, her gaze sweeping across the students, lingering on each of the male faces. The smile on her lips deepened. "Shibari is a very serious art form that requires complete concentration. Any form of joking, horseplay, or disrespect is not permitted. All actions must be strictly in accordance with my instructions. No unauthorized movements. Anyone who violates discipline will be immediately disqualified from the course and receive a demerit. Do you understand?" "We understand!" the entire class responded in unison, the male voices particularly loud. "Excellent," Qin Yun nodded with satisfaction, then turned to Li Yuanyuan. "Teacher Li, let's begin. Please stand in the center of the mat, facing everyone." Li Yuanyuan took a deep breath, trying to make her steps appear steady as she walked to the center of the mat and stood still. The students below voluntarily formed a semi-circle, the boys crowding the front, the girls lingering behind, all eyes focused on the two women in the center of the space. "The first step in Shibari is selecting the appropriate rope," Qin Yun said, taking a coil of hemp rope from a nearby toolbox and unfurling it for everyone to see. "Today, we will be using a custom-made cotton-hemp blend rope, eight millimeters in diameter and seven meters long. It has moderate softness, making it less likely to leave marks on the skin, while also providing enough friction to ensure the knots are secure." As she spoke, she walked behind Li Yuanyuan, displaying the rope in front of her. Then, she suddenly lowered her voice, speaking in a volume only Li Yuanyuan could hear. Li Yuanyuan's face flushed to her earlobes, but she still nodded and closed her eyes. "For our first lesson today, I will teach you a fundamental and classic Shibari technique – the Kikkō-dori, or tortoise shell tie," Qin Yun's voice returned to its normal teaching tone. She flicked the rope in her hand, producing a crisp sound in the air. "The name of this technique comes from the shape of the knot, which forms a diamond-shaped grid in front of the bound person, resembling a tortoise shell, hence the name." The boys in the audience held their breath, their eyes wide, afraid to miss any detail. Lin Yi stood among them, feeling his heart about to leap out of his throat. The unruly member in his crotch was already showing signs of arousal. He quickly pulled down his school uniform jacket, trying to conceal the obvious bulge. "First, fold the rope in half and find the midpoint," Qin Yun's movements were clean and precise. The hemp rope seemed alive in her hands, twisting and turning with effortless grace. "Place the midpoint at the back of the neck of the person being bound, with the two ends hanging down in front of the shoulders." She stood in front of Li Yuanyuan, her hands sliding past Li Yuanyuan's neck, letting the two strands of rope hang down from her collarbones. Li Yuanyuan's breathing became noticeably more rapid, and beneath her white silk blouse, her chest rose and fell with increasing prominence. "Next, tie the first knot at the chest," Qin Yun's hands moved to Li Yuanyuan's chest, crossing the two strands of rope and tying a simple knot. "Note that the position of this knot is crucial. It must be precisely in the center of the sternum, not deviating. Too high will affect the subsequent rope path, and too low will prevent the formation of a complete diamond grid." Lin Yi's gaze was fixed on Qin Yun's hands and Li Yuanyuan's chest, his Adam's apple bobbing. He could clearly see the rope passing between Li Yuanyuan's full breasts, the fabric of her white shirt indenting slightly where the rope pressed against it, accentuating the curves even more. Li Yuanyuan's lips were pressed tightly together, her eyes closed, her eyelashes trembling slightly. Qin Yun continued downwards, the two strands of rope passing under Li Yuanyuan's armpits to her back, crossing there, then looping back over her shoulders and through the knot at her chest, forming a complete loop. Her movements were skilled and fluid, each knot tied cleanly and precisely, truly appearing to be a rigorous craft. "Now for the crucial step," Qin Yun's voice held a subtle, almost imperceptible smile. "The two ends of the rope hang down in front, passing between the legs – note, this part of the rope path is called the 'leg rope,' and it is the most central part of the entire Kikkō-dori." As she spoke, she held the two ends of the rope in her hands, moving from Li Yuanyuan's lower abdomen downwards, slowly, inch by inch, guiding the rope into the gap between her legs. Qin Yun brought Li Yuanyuan’s feet together and continued tying the rope she’d left around her calves, wrapping it three times around her ankles. The bones in her ankles were quite prominent, and as the rope passed over them, Li Yuanyuan’s toes curled involuntarily—the skin there was more sensitive than on her calves, and the rough texture of the hemp rope rubbed against her ankle bones through the thin stockings, causing a faint, prickling sensation. “You have to be especially careful with the tension when tying the ankles,” Qin Yun said as she tightened the rope. “There are quite a few bones and tendons in the ankle area; if the rope is too tight, it will compress these structures, causing discomfort or even injury. “So when tying the ankles, apply slightly less pressure than when tying the thighs and calves, but at the same time, ensure the knots are secure enough so they don’t come loose.” After wrapping the rope around her ankles three times, she tightened it in the middle and tied a knot, firmly securing both ankles together. Then she picked up a thinner hemp rope and began tying the feet. “Tying the feet is one of the parts of the entire bondage setup that most enhances the sensation of restraint, ” Qin Yun’s fingers glided gently over the top of Li Yuanyuan’s foot, feeling the structure of the bones beneath the stockings. “Because the ankles and soles are extremely sensitive, the right amount of restraint can create a very intense sensation. But at the same time, foot bondage also requires the most skill, because there are many bones and joints in this area, and the slightest misstep can cause discomfort.” She first used a thin cord to secure an additional loop around both of Li Yuanyuan’s ankles, then threaded the cord through the center of the instep, looped it under the sole, and brought it back up over the instep on the other side. Repeating this several times, she formed a neat looped structure across the middle of the soles of both feet. Every time the rope passed over the sole of her foot, Li Yuanyuan’s toes would involuntarily curl—the skin on the soles of her feet was one of the most sensitive areas on her entire body, and the itchy, tingling sensation caused by the hemp rope rubbing against her through the thin stockings made her want to pull her feet back. But her ankles were tightly bound, leaving her unable to pull them back. She could only let Qin Yun’s fingers and the rope weave back and forth across the soles of her feet, delivering wave after wave of sensations that made her blush and her heart race. Qin Yun held Li Yuanyuan’s foot in her hand and could feel the faint tremors coming from it. The sole beneath the stockings was warm and soft, and the curve of the arch fit perfectly against her palm. As she explained the path of the rope, she continued her work, wrapping the rope from the top of the foot to the sole, tightening it at the arch, then wrapping it back from the sole to the top of the foot, forming a crisscrossed pattern. “The knot for the sole should be tied on the top of the foot—this looks neat and won’t dig into the bound person when weight is applied,” ” Qin Yun said, tying a delicate knot on the instep of Li Yuanyuan’s left foot before moving on to the right foot. “The rope’s path must follow the foot’s natural curve; you mustn’t forcefully twist the joints. This is a very important ergonomic principle in rope bondage.” After securing the soles, Qin Yun pulled out two strands of rope and began wrapping them around Li Yuanyuan’s toes. She gently wrapped the thin cord around the base of the big toe, leaving a faint indentation on the stocking, then threaded the cord through the gap in the stocking between the big toe and the second toe, around the space between the second and third toes, then sequentially through the gaps in the stockings between the third and fourth toes, and between the fourth and little toes, finally tightening and tying a knot on the outer side of the little toe. The elasticity and smoothness of the stockings made this process effortless—Qin Yun’s fingers gently parted the fabric between each pair of toes through the stockings, allowing the thin cord to slide smoothly through the gap, leaving distinct cord marks on the surface of the stockings that separated each toe. This method secured each of Li Yuanyuan’s toes with the cord, preventing her from curling or stretching them, forcing her to maintain a slightly splayed position. This sensation of having her toes bound was even more subtle than the restraint on her ankles and soles—the toes are among the most flexible and sensitive parts of the human body, and rarely does anyone touch them in everyday life, let alone secure them one by one with rope. Now, bound so meticulously by Qin Yun, Li Yuanyuan felt a sense of shame and helplessness she had never experienced before, as if every part of her body were completely under control, with not even the slightest bit of freedom remaining. “All right, a complete full-body bondage setup is now finished.” ” Qin Yun stood up, took a step back, and smiled with satisfaction at her work. “From the toes to the soles, from the soles to the ankles, from the ankles to the calves, from the calves to the thighs—plus the tortoise-shell bind and the rear-hand bind on the upper body— —every part is firmly secured with rope. This is the complete form of the first rope-binding combination I’ll be teaching you today. Of course, for the more advanced ‘Four Horses Gathering Hooves’ technique, the feet must be pulled behind the back and tied to the hands to form a reverse bow shape. However, since this is our first class, we won’t go that far for now. In future sessions, I’ll gradually teach you how to achieve more complex bondage forms.” Li Yuanyuan sat on a cushioned chair, her entire body tightly bound with rope. Her legs, from the base of her thighs to her ankles, were wrapped layer upon layer with hemp rope; her feet were tied together, and even her toes were separated and secured one by one. She couldn’t even move a single toe; all she could feel was the constant, gentle pressure of the rope beneath her stockings. The “tortoise shell” bind and the “behind-the-back” bind on her upper body left her completely immobilized. Although the crotch rope had loosened slightly after she sat down, it still dug firmly into the most intimate spot between her legs, causing a subtle yet persistent friction with every breath. She could feel her panties were already soaked through. That damp sensation spread from between her legs, clinging stickily to her skin and filling her with overwhelming shame. She was a teacher—a mature woman in her thirties—and yet here she was, bound like this in front of her entire class, experiencing this kind of reaction. If her students found out, how could she ever face them again? How could she ever stand at the front of the classroom to teach and guide them? But the more she thought about it, the more sensitive her body became. The sensation of every rope tightening against her body grew exceptionally vivid—the diamond-patterned rope crisscrossing her front tightly encased her chest and abdomen; the ropes binding her hands behind her back held her arms firmly in place; and the ropes on her legs prevented her from even bending her knees. and the restraints on her ankles and the soles of her feet made it impossible for her to take even a single step. Her entire body was bound into a position where she could not move a muscle, sitting in the chair at the mercy of others’ gazes—this sensation stirred within her an unprecedented, complex, and indescribable mix of emotions. Lin Yi quickly stood up and moved behind Shen Yue, beginning the rear tie. This step was better than the crotch rope, at least it didn't require direct contact with those sensitive areas. He pulled Shen Yue's hands behind her back, crossed them, and began to wrap the rope—three loops around each wrist, tightened, knotted, then along the arms, wrapping a few times around the forearms and upper arms. Shen Yue's arms were slender, her skin smooth with almost no blemishes. As the rope wrapped around them, he could feel the delicate texture of the skin beneath. Her shoulders were pulled back slightly by the rear-bound arms, naturally pushing her chest forward. The diamond-shaped rope patterns on her front were stretched tighter, and the crotch rope was thus more deeply embedded in her body. Standing behind her, Lin Yi could see the soft downy hair on her nape, the skin behind her ears flushed crimson, and even the slightly protruding vertebrae beneath the collar of her school uniform. "Alright, the turtle shell tie and rear tie are complete," Lin Yi stepped back, looking at his "work." He was drenched in sweat, panting heavily, as if he had just run a thousand meters. Shen Yue stood there, bound securely. The crisscrossing hemp ropes outlined alluring curves on her youthful body. In front, a neat row of diamond-shaped rope patterns extended from her collarbone to her lower abdomen, each one fitting snugly against her, accentuating her slender yet curvaceous figure. Her hands were firmly secured behind her back, unable to move. Most agonizing were the three crotch ropes between her legs, tightly cinching her most private parts, causing a subtle but undeniable friction with every breath. She stood there, her school uniform creased by the ropes, looking both disheveled and alluring. Looking at Shen Yue like this, Lin Yi felt an extremely complex mix of emotions—satisfaction of having achieved his desire, excitement at seeing his goddess bound by his own hands, a certain hidden desire for conquest, and a trace of inexplicable pity. This girl he had a crush on since freshman year, a girl he didn't even dare to speak to, was now standing before him, immobilized by his ropes, presented in the most shameful posture. This contrast sent a near-dizzying pleasure through his mind. "Not bad," Wang Hao patted his shoulder, winking and saying, "Your technique is pretty good, man. You managed this on your first try, much better than me. Look at mine—" He gestured towards another group he was responsible for. The girl in that group's ropes were loose and sloppy, no comparison to Lin Yi's. Before Lin Yi could reply, Qin Yun's voice suddenly echoed throughout the venue: "Good, I see most groups have completed the turtle shell tie and rear tie portions. Excellent. Now, we will proceed with binding the legs and feet." As she spoke, she walked to the center of the area, accompanied by Li Yuanyuan, who was also tightly bound. Li Yuanyuan was supported by two girls on either side, struggling to shuffle to the center. Her feet were tied together, forcing her to walk in small hops. Each hop made the ropes on her body sway, and the crotch rope rubbed back and forth between her legs, making her entire face flush crimson. Only after the two girls helped her back onto the padded chair and she sat down did she let out a sigh of relief. Qin Yun stood beside the padded chair, holding new ropes, and addressed the entire group: "I've already demonstrated the leg-binding steps, so I won't repeat them here. I will now focus on emphasizing the foot binding," she crouched down, picking up Li Yuanyuan's bound feet. Her fingers pointed to her instep, covered by the stocking. "Foot binding is one of the most crucial parts of the entire restraint structure for enhancing the sense of confinement, as the ankles and soles of the feet are highly sensitive. Proper binding will bring a very intense experience. Pay attention to the rope paths I showed earlier—starting from the ankles, wrapping around the instep, passing under the sole, tightening at the arch, and finally securing the toes separately. Every step must be steady and precise, no rushing. Alright, each group can now continue with the leg and foot binding. Guys, remember the key points I emphasized—appropriate tightness, even spacing, and secure knots. Begin." Lin Yi took the new ropes from Wang Hao and crouched down in front of Shen Yue, preparing to bind her legs. Shen Yue was still standing there, hands bound, the diamond-shaped rope patterns of the turtle shell tie in front, the crotch rope cinching between her legs. She lowered her head, looking at Lin Yi crouching before her. Their eyes met for a brief moment at close range before they both hastily looked away. Lin Yi noticed a thin mist in Shen Yue's eyes, unsure if it was from shyness or the stimulation from the earlier rope. Her eyelashes were long, casting small fan-shaped shadows under the light, trembling slightly like butterfly wings. "I... I'm going to start binding your legs now," Lin Yi said with difficulty, his voice hoarse. "Mmm," Shen Yue's response was still simple, her voice soft, with an undisguised tremor. Lin Yi began wrapping the rope around Shen Yue's thighs, starting from the root and working his way down. Because Shen Yue was wearing school uniform pants rather than a skirt, the tactile feedback from the rope was different from when Li Yuanyuan was demonstrated—through the fabric, the sensation wasn't as direct. However, the pants were thin, and he could still feel the shape and warmth of her thighs beneath. With each wrap, he used his fingers to check the tightness, ensuring the rope was snug but not too constricting. Shen Yue's legs were slender, her thigh circumference only about one and a half times his palm's circumference. Three or four wraps of the rope covered a small section. He deliberately slowed down, cherishing each precious moment of contact with Shen Yue's body, wanting to prolong these moments as much as possible. With every wrap, he could feel Shen Yue's thighs trembling slightly. She was clearly nervous, her muscles tensed, but as the rope wrapped around, her body gradually relaxed, or rather—it began to adapt to the feeling of being restrained. When he reached the middle of her thighs, Lin Yi encountered a slight problem. Due to the crotch rope, three strands passed between Shen Yue's legs, digging into the crevice of her most private area. Now, as he was wrapping the rope around her upper thighs, the rope path would inevitably cross the crotch rope. He needed to carefully adjust the rope path at the points where the crotch rope passed, making the thigh ropes go around the crotch rope's path while ensuring overall security. This meant his fingers had to get even closer to Shen Yue's most private area between her legs. Shen Song Yuqing didn't reply immediately this time. The prompt box lit up and went out, went out and lit up again, back and forth several times, before finally popping out a sentence: "I'll send you a picture, see if it's your school." Without waiting for Lin Yi's response, an image popped up. Lin Yi clicked on it. The image was a screenshot of a forum. The interface was gray and white, and the title was written in bold black font: "Real shots from the BDSM class at No. 2 High School, female teacher tied up in public, expression out of control." The post was embedded with three photos, all of them blurred, but the blur only obscured the lower half of the face, leaving the eyes and brow bone exposed. In the first photo, a woman in a white shirt tilted her head back, her mouth slightly open, two blushes burning from her cheekbones to the roots of her ears. In the second, her eyes were closed, her brow furrowed, her lips half-bitten, as if enduring something, or perhaps welcoming it. The third photo was taken from the most cunning angle, cutting across from the side, capturing her chest tightened by ropes and the faintly visible rope marks between her thighs. Lin Yi only glanced at it, and his whole body felt as if someone had struck him on the back of the head with a club. This was fucking Li Yuanyuan. The photos weren't very clear, but anyone who knew her would recognize her at a glance. That outfit, that expression, matched Li Yuanyuan from the multi-purpose hall yesterday perfectly. Lin Yi's fingers gripping his phone tightened, his knuckles turning white, and a cold sweat broke out on his back. He had been so disoriented all day by the BDSM class, the Yifu Building, and the library that he hadn't browsed any posts and had no idea things had escalated to this extent. His phone vibrated again. Song Yuqing sent a message: "This is your school, right?" Lin Yi's throat felt dry. He typed and deleted, deleted and typed, finally replying with just one word: "Yes." "Oh my god..." Song Yuqing quickly replied, followed by several exclamation marks. "I saw several people sharing this post when I was browsing my feed tonight. I thought it was fake at first, but when I clicked on it, it really was your school. Do you know this teacher?" Lin Yi didn't answer immediately. He switched back to the screenshot, zoomed in with two fingers, and looked at the third photo again. Li Yuanyuan in the photo was so tightly bound by the ropes that her clothes were wrinkled, her hip-hugging skirt slightly lifted, and a thin red mark was clearly visible on the inside of her thigh. His mind buzzed, as if a bee had been stuffed into it. He had been there yesterday, he had seen Li Yuanyuan like that with his own eyes. But seeing it in person was one thing, and seeing it in a photo was another. The photos were clearer, more explicit, and more heart-pounding than his memory. The photographer had chosen an extremely tricky angle, capturing Li Yuanyuan's most embarrassing and uncontainable moments in almost every shot. "I know her... she's my homeroom teacher." Lin Yi typed these words, his Adam's apple bobbing. "Your homeroom teacher?!" Song Yuqing sent a "shocked" emoji. "My god, then your class must be going crazy, right? I saw many people in the comments saying this teacher is finished." Lin Yi stared at the words "is finished," and his heart felt as if something was fiercely twisting it. He remembered Li Yuanyuan in the equipment room this afternoon, remembered her arching her neck, bending her waist, her underwear soaked. Those images overlapped with these photos through the lens, making his breath burn. He took a deep breath, trying to make his reply sound normal: "Anyway, I haven't heard anyone mention this matter at school today." "So you weren't the first to know?" Song Yuqing asked. "Not really," Lin Yi replied. "I only found out when you sent it to me." "..." Song Yuqing sent a string of ellipses, and after a few seconds, added, "Then you're quite unlucky, having your homeroom teacher's photos like this posted online, and finding out from someone outside your school." Lin Yi gave a wry smile. Unlucky? He didn't think so. He just couldn't quite articulate what he was feeling right now. Song Yuqing's words reminded him – this matter had spread, spread far and wide, even to people in key high schools. But the more it was like this, the more his head felt swollen: Why was she tied up in the equipment room? Why was she only wearing that black lace? Why was there such a strange bulge in her underwear? One question after another blocked his throat, and he couldn't figure any of them out. "Damn, is this really a teacher..." Song Yuqing sent another message, as if talking to herself. "This photographer is too good, my classmate said the third photo looks like a photoshoot." Lin Yi stared at the word "photoshoot," and his heart skipped a beat. He didn't want to get into a debate with Song Yuqing about the "photoshoot," but his mind uncontrollably replayed the details in the photos. The red marks left by the ropes, her slightly parted legs, and the small section of rope peeking out from under her skirt. He closed his eyes, forcing himself to reply: "The photographer is indeed unethical." Shen Yue's private parts were like a flower that had been crushed open, its petals swollen and glistening, the color deepening from pale pink to ripe red. Juice welled up from within, thickly coating her vulva and dripping down in strands. Lin Yi extended a finger and gently swiped across her entrance. Shen Yue's entire backside arched upwards, and a deathly whimper escaped her throat. The sound clutched at Lin Yi's lower abdomen like a small hand. His finger probed deeper, and as soon as a knuckle entered, it was bitten by the hot, soft flesh within. Shen Yue's vulva was terrifyingly tight, as if it wanted to swallow his finger inch by inch, from tip to root. Lin Yi's finger felt numb from the suction, the sensation of being so tightly enveloped, wet and hot, made his mind explode. He tried to twist it, and Shen Yue's body convulsed with each movement. The saliva pooling at the edge of the gag had almost become a continuous stream. "Master, don't rush..." Qin Yun whispered from the side, "Miss Shen is tight down there, you need to take it slow. Rub her on the outside for a while longer, then go in when she's softened." Lin Yi felt like he was being instructed on how to disarm a bomb. He withdrew his wet finger, its tip already coated in a layer of pale white mucus. He smeared the liquid onto Shen Yue's labia, then pinched her clitoris between two fingers and gently squeezed. Shen Yue jolted as if struck by high voltage, her entire spine arching to its limit. The sound from behind the gag was so sharp it almost pierced eardrums. Her body writhed violently on the floor, making the ropes creak. But the structure of the hogtie, with her body arched back, turned every struggle into a tightening, pulling her deeper, making her weaker. Lin Yi's hands grew more practiced. He massaged her clitoris, feeling it transform from a tiny nub of flesh into a hard little bead. He pulled Shen Yue's underwear completely down, bunching them at the backs of her knees, leaving her lower body completely exposed. The skin between Shen Yue's legs glistened wetly in the light, even her butt crack shimmered with moisture. "Does Master want to see Teacher Li?" Qin Yun asked. Lin Yi looked up, meeting Li Yuanyuan's eyes. Li Yuanyuan had been watching him the entire time. Even with her mouth gagged and her body contorted by the red ropes, her gaze remained fixed on Lin Yi, as if trying to burn him through. Her eyes held shame, anger, pleading, and something deeper and more intense, like melting wax, or red-hot iron. She watched him toy with her most prized student in his palm, listening to Shen Yue's lewd, uncontrollable whimpers. The water in her own body had long since flowed more than Shen Yue's. Her black thong was soaked through, the thin straps digging into her vulva, her entire lower half glistening with a decadent sheen of moisture. "Teacher Li wants it too," Qin Yun said, walking over to Li Yuanyuan and nudging the inside of her thigh with the tip of her shoe. Li Yuanyuan squeezed out a deep, heavy groan from her throat, as if trying to bite through the gag. Her hips rubbed slightly within the ropes, the wetness at her vulva flashing in the light, like it was breathing. Li Yuanyuan's skin was much hotter than Shen Yue's. She trembled as if feverish, and every inch of skin Lin Yi touched broke out in goosebumps. Lin Yi's fingers slid up her spine, and when they reached the middle of her shoulder blades, her body suddenly spasmed, and a small amount of what seemed like urine sprayed out from beneath her, only to be forcefully held back. Lin Yi looked down; her thong was so wet it could be wrung out, and the liquid pooled on the pad was twice as much as Shen Yue's. Lin Yi reached into her bra cup and cupped one of her breasts. Li Yuanyuan's breasts were large and soft, like a mass of dough that had been kneaded to its limit. Lin Yi's fingers sank in, the flesh bulging between his fingers, slick and hot. He pinched her nipple, like gripping a small, hard ball, and gave it a firm tug. Li Yuanyuan's body tensed like a drawn bowstring, veins popping on her neck, and a muffled, indistinct shriek, suppressed by the gag, escaped her throat. "Teacher Li loves having her breasts played with the most," Qin Yun said, a hint of malicious laughter in her voice. "Don't you see how hard they are? Her nipples are like little pebbles." Lin Yi's other hand moved to Li Yuanyuan's front, cupping her other breast. He held both breasts in his hands simultaneously, squeezing and kneading them, his nails occasionally scraping her nipples. Li Yuanyuan's body shook violently, her hips and abdomen contracting, as if in welcome, or perhaps in escape. Her hands, tied behind her back, were clenched tightly, knuckles white, the red ropes digging into her wrists, leaving deep red marks. Lin Yi looked up, his gaze shifting to the right, settling on Song Yuqing. Song Yuqing's body went limp with fear. She watched Lin Yi handle Li Yuanyuan, the terror in her eyes like two candle flames flickering in the wind. But she couldn't move, couldn't escape, and could only expose all her reactions in the light, including the growing wet patch on her underwear and the saliva dripping like broken beads from beneath her gag. Lin Yi released Li Yuanyuan and walked towards Song Yuqing. His shadow fell upon her, like a pair of black wings unfurled. Song Yuqing began to shake her head desperately, emitting muffled cries from her gagged mouth, her body thrashing wildly within the ropes. But the more she struggled, the deeper her arch became. The pink fabric of her top shifted, revealing a large expanse of snow-white breast and half of a pale pink nipple. "I didn't expect to see you here," Lin Yi crouched down, the lips beneath his mask curving into a low, husky smile. Song Yuqing started to cry. Tears rolled down her wide-open eyes, mixing with her saliva, making her entire face wet and shiny. She shook her head, then nodded, unsure of what she was doing. Lin Yi's hand slid under her armpit, lifting her slightly. Her body was impossibly light, like a bird with its wings broken. Lin Yi held her in his arms, her back against his chest, his arms passing under her armpits, and from either side, he cupped the two small mounds on her chest. Li Yuanyuan stood before the door of the "Rope Art Club Instructor's Office," her hand trembling as she raised it to knock. Nearly twenty hours had passed since Qin Yun had first bound her with rope and inserted a vibrator in the library's equipment room yesterday afternoon. Twenty hours. The rope had been inside her for twenty hours, the vibrator too. In between, she had accompanied Qin Yun to the night market, wearing that black slip dress and Qin Yun's trench coat, walking among the crowds for nearly half an hour. Later, Qin Yun drove her home—her own home. Her husband was away on a business trip, and the house was empty, the curtains drawn tight. Qin Yun had tormented her for most of the night in her home before finally leaving. And she, with the rope, now soft and soaked in bodily fluids, and the vibrator, warm from being inside her, had endured the rest of the night alone. She couldn't recall how she'd gotten back to the car from the night market. She only remembered sitting in the passenger seat, her body wracked by waves of vibrations that blurred her consciousness. Every time she neared sleep, the vibrator would buzz to life, like a small insect hidden in the darkness, biting her precisely when she was most relaxed. Eventually, she couldn't take it anymore. She thought she cried, or maybe she didn't. She remembered clutching Qin Yun's arm, repeatedly begging, "Turn it off, please turn it off," but Qin Yun merely turned her head, looked at her with those eyes, and said, "It's not time yet." What happened after they returned to her house, she remembered more clearly. Qin Yun had told her to remove her trench coat and dress, leaving her in only the black slip. She was instructed to lie down on the living room's coffee table. The rope was tightened to its limit, and the vibrator was set to a continuous low frequency. Qin Yun sat on her sofa, one leg crossed over the other, holding a glass of water, and chatted with her unhurriedly. They talked about how many years she had been a teacher, how often her husband returned, and what her favorite sexual positions were. Li Yuanyuan lay there, like a fish pinned to the coffee table, her body driven to madness by the long, tireless vibrations, forced to grit her teeth and answer questions that made her so ashamed she wanted to die, word by agonizing word. Qin Yun asked, "Does your husband touch you like this?" Li Yuanyuan remembered shaking her head, then nodding, and finally burying her face in her forearm. The rope was digging so deep that even the slightest movement of her head would tug at the knot, pressing it harder against the already swollen, misshapen nub. Later, Qin Yun led her into the bathroom. When the cold water cascaded down, Li Yuanyuan screamed, then bit her lip fiercely. Qin Yun made her stand against the tiled wall, legs spread, forbidden to close them, forbidden to move away. The stream from the showerhead poured down her neck, tracing her collarbones, chest, abdomen, and finally flowing between her legs. The rope, saturated with water, became thicker and heavier, coiling around her like a living snake. The vibrator slipped half an inch deeper under the rush of water, and Qin Yun pushed it back. After several repetitions of this, Li Yuanyuan was trembling so much she could barely stand. She could only brace herself against the wall, her fingertips scraping faintly against the tiles. Qin Yun, holding the remote control, leaned against the bathroom sink, as if watching a private late-night movie. She had only one rule for Li Yuanyuan: no closing her legs, no hiding, no touching herself. Tormented by the water, the rope, and the vibrator, Li Yuanyuan felt like she was being roasted over a fire. A few times, she was on the verge—the sensation rising from her abdomen to her throat, her vision starting to blur—but Qin Yun would lightly press a button on the remote, and with a "beep," everything would reset. That feeling was worse than death. Finally, Qin Yun led her to the bedroom. Li Yuanyuan knelt by the bed, her face buried in the bedding. Qin Yun repeatedly pulled the rope up and down from behind her, each pull like a saw grinding against her most sensitive spot. The vibrator turned on and off, its rhythm out of sync with the rope, one pushing upwards, the other tightening inwards. Li Yuanyuan didn't know how long she knelt, or how much she had leaked. She only remembered Qin Yun finally gripping both ends of the rope and, like reining in a wild horse, pulling back slowly, deliberately. The rope, soaked all night, repeatedly ground against her swollen clit, each pull eliciting a muffled cry swallowed by the bedding.
