Summon the elf, then tie her up.

He lowered his head slightly, looking at the blue-haired girl frowning before him. He finally squeezed out a sentence from his throat, his voice trembling, his volume uncontrollable and wavering: "Th-that... excuse me, can I... bind you with electrical tape?" Although he had always harbored the thought of binding, he had never done it before, nor did he know how. Electrical tape seemed like the most suitable choice. The air instantly fell silent. The elf raised an eyebrow, as if she hadn't heard him clearly. Her emerald eyes swept over him from head to toe, her gaze carrying a tangible weight, scrutinizing him like he was some strange, peculiar monster. Two seconds later, she let out a snort. That laugh was laced with undisguised mockery. Immediately after, she rolled her eyes dramatically, her usual cool demeanor instantly replaced by undisguised contempt. The disgust in her tone was almost palpable: "Human brat, is your mind filled with nothing but vulgar, unspeakable filth?" Lin Chen's face flushed crimson, all the way to his earlobes, his eyes instantly watering. He was flustered and at a loss, waving his hands and taking half a step back. His voice was laced with a sob as he stammered an apology: "I-I'm sorry! It was presumptuous of me! I shouldn't have said such a crude thing! If you're unwilling, I'll send you back immediately, I won't delay you by even half a minute! I'm truly very sorry!" As he apologized, his mind was a chaotic mess. He had indeed been too fanciful. Which elf would respond to a summoning only to hear such an absurd request from a stranger? The fundamental nature of a human summoning an elf was a mutual choice, a contract to enhance their respective strengths. But by speaking so directly, the contract was likely ruined... He expected the elf before him to mock or even curse him before leaving. His shame gradually subsided, and he let out a soft sigh, no longer looking at her. The elf, seeing his flustered and disappointed expression, suddenly froze. This was the first time she had encountered someone like this. He didn't try to bribe her with promises, nor did he deceive her. He had simply stated his desires so directly, without even waiting for a contract or for any emotional connection to form. The summoning circle was meticulously drawn, the materials were top-tier, showing clear effort. His spiritual energy was clean and pure, devoid of any malice, almost entirely lacking in aggression. He had summoned her, and his only request was to ask if he could bind her with electrical tape. Furthermore, after being insulted by her, this man hadn't become angry or persistent. His first reaction was to apologize and offer to send her back. His face was beet red, his eyes filled with helplessness, but not a trace of lewd desire. Only undisguised nervousness and a flicker of fading hope. In reality, she had only recently come of age, but she had indeed never heard of the "binding" fetish before. The insult "brat" was her tried-and-true tactic: using her seemingly aloof and unapproachable aura to ward off those who coveted her. She glanced again at the small rental room. It was clean and tidy. University textbooks were piled on the desk, and the edge of some tape peeked out from a drawer, clearly prepared in advance. She could even sense from his spiritual energy that cautious longing, one he himself dared not confront. Such a person would likely find it difficult to do anything excessive to her. And this request, while sounding bizarre, posed no actual risk to her. With her strength, breaking free from ordinary restraints was more than enough. With this thought, she decided to take control of the situation and tease him a little. She crossed her arms, took a step forward, her boots making a crisp sound on the floor, and advanced towards Lin Chen. Lin Chen flinched backward, his back pressing against the wall. He didn't dare to look up, his gaze fixed on the tips of her boots, his heart pounding as if it would leap out of his throat. "Just to bind you with electrical tape?" The elf's voice echoed above him, laced with a playful amusement. Lin Chen's head snapped up, his eyes instantly lighting up like suddenly ignited stars. He nodded frantically, his head bobbing like a pecking chick: "Yes! Just to bind! Absolutely no other requests! I will never harm you! If you feel uncomfortable at any time, you can stop me, and I'll untie you immediately! You can leave whenever you want after I untie you!" Fearing she wouldn't believe him, he hastily added: "The electrical tape I bought won't hurt your skin, won't leave residue, and won't even cause pain! Really!" Seeing him eagerly trying to prove himself, his face flushed again, the elf couldn't help but laugh. "Yes." She spoke, her two words light and airy, yet they struck Lin Chen like a thunderclap, leaving his mind blank. "But I have a condition." The elf's eyes met his, her tone becoming a little more serious. "Sign a contract." She raised an eyebrow, her voice carrying a hint of challenge at the end: "Dare you, brat?" Her arms were held fast, and as the tape wound around her legs, they gradually became impossible to separate even by a sliver. She could clearly feel her body slowly, completely losing control. This unfamiliar sensation made her instinctively try to mobilize her internal spiritual energy, attempting to break free from the flimsy restraints. But the moment her mental energy touched the contract mark on the back of her hand, she felt a powerful tug. It was Lin Chen's mental energy. The contract was bidirectional; she could share in Lin Chen's spiritual energy nourishment, and Lin Chen could sense her power fluctuations. At this moment, Lin Chen's mind was highly concentrated, his entire focus on her. That extreme focus, the cautious cherishing, and the desire suppressed for ten years, hidden in the deepest recesses, all flowed through the contract mark, an unending stream like a warm torrent, crashing directly into her sea of consciousness. Avila froze. She had been curious whether a human male from a top university could actually support her cultivation and growth. Now, feeling this clean and pure mental energy, she instinctively reached out, wanting to sense the source of this power, to see what this kid's sea of consciousness was like. But the instant her mental energy touched Lin Chen's, the warm torrent gave a gentle tug, like an invitation. She didn't know what it was, but considering herself powerful, she unhesitatingly released her mind to accept the pull. "Ugh!" Avila let out a muffled groan, her body jolting violently. Her legs, which had been standing steadily, suddenly went weak, and she could only lean against the wall behind her to remain upright. The spiritual energy within her felt as if it had been instantly sealed by something, vanishing without a trace! Even bound, she could usually break free from the tape with her spiritual energy at any time, but now, not only could she not mobilize her spiritual energy, her body was so weak she couldn't exert any force, leaving her at the mercy of the tape binding her. How could this be?! Her face instantly paled, her eyes filled with shock and a hint of imperceptible panic. She had never heard of such a situation occurring right after a contract was formed, nor did she want this timid boy to see her lose composure and ruin the cool, aloof older sister image she had always maintained. Meanwhile, Lin Chen, squatting on the ground, also felt the sudden change. A scorching warm current surged from the contract mark on his wrist, flowing through his veins and throughout his body. He had been just an ordinary college student with mediocre mental energy, needing to copy summoning arrays hundreds of times before drawing them correctly. But now, he felt his sea of consciousness become incredibly full, his senses amplified manifold. He could even clearly hear Avila's accelerated heartbeat and sense the panic transmitted through the contract, hidden beneath her composed exterior. He also vaguely sensed some strange new abilities within his body. He abruptly stood up, looking at Avila, whose face was pale and body trembling slightly. He immediately panicked, "Wh-what's wrong? Are you feeling unwell? I'll untie you right away!" As he spoke, he reached out to tear off the tape, but Avila's sharp voice stopped him, "Don't touch!" Avila bit her lower lip, forcibly suppressing the panic in her heart, striving to maintain her usual cool tone. Yet, the slight tremor in her voice betrayed her discomfort. "It's just the contract forming, a bit of spiritual energy fluctuation. What? Did you lose your nerve halfway through tying me?" She intended to use her usual taunts to regain control, but when she looked up at Lin Chen, she found that the boy before her seemed different. The previous Lin Chen had averted his gaze, exuding timidity and nervousness, unable to meet her eyes for more than three seconds. But now, although the panic hadn't entirely faded from his face, his eyes were astonishingly bright. His previously slightly hunched back had straightened, and a natural sense of pressure, emanating from the surge of his spiritual energy, surrounded him—a pressure she had never seen before. Lin Chen also slowly came to his senses. He could clearly feel Avila's power, temporarily transferred to him through the bidirectional contract, while she herself was currently unable to resist. This realization sent a jolt through his spine. He had always been timid, cowardly, unable to hold his head up in front of anyone, even afraid to admit his own desires. But now, the elven girl he longed for was bound by him with tape, temporarily powerless, leaning against the wall for him to gaze upon. An unprecedented sense of control surged through his entire body. His palms were still sweating, his heart still racing, but his gaze slowly steadied, falling on Elara's flushed cheeks. He took a step forward, leaning down slightly, bringing himself extremely close to her. His voice, though still carrying a barely perceptible tremor, was much steadier now, imbued with a new dominance. "Are you... really okay?" His eyes swept over her body, firmly secured by tape, and his Adam's apple bobbed. Elara's heart tightened, but she refused to yield. Gritting her teeth, she said, "What could happen to me? Stop wasting time. Either continue, or let me go." Lin Chen was silent for a few seconds, then retrieved a box from the cabinet. He gently opened it. The interior was lined with black velvet, and in the center lay a small, milky-white, soft silicone sphere. The sphere had several tiny ventilation holes in its center and was attached to thin elastic straps on either side. He had bought it a long time ago, never daring to bring it out, but now, as if possessed, he offered it to Elara. Elara's gaze fell on the strange object. She frowned, her eyes filled with confusion. She had never seen anything like it in the elven realm. It didn't look dangerous, but she couldn't guess its purpose. "What is this?" she asked, her curiosity evident. Lin Chen's face flushed again. He tightened his grip on the box and whispered, "It's... a gag." "A gag?" Elara repeated the word, even more bewildered. "What is it for?" "It's... you put it in your mouth, to hold your teeth in place so you can't close your mouth," Lin Chen's voice grew softer, avoiding her gaze. "This one is soft silicone, it won't hurt, and it won't damage your teeth. It has ventilation holes, so you can still breathe." He had expected Elara to get angry, to call him disgusting, to tell him to throw it away. But to his surprise, Elara merely raised an eyebrow. She looked at the gag in his hand, a flicker of curiosity in her eyes, and a hint of defiance. It was just a silicone ball for her mouth, wasn't it? She was already bound by tape, what was she afraid of? Refusing now would make her seem cowardly and ruin the aura she had maintained. She bit her lower lip, then looked up at Lin Chen, a challenging glint in her eyes. "Oh? Put it in me and let's see. I want to know what this thing is supposed to do." Lin Chen's head snapped up, his eyes wide with disbelief. He had only taken it out on a whim, never expecting her to agree. His heart pounded as if it would explode. Holding the gag, he walked step by step towards Elara, leaning down again, bringing himself incredibly close. He could clearly smell her faint, delicate fragrance, feel her warm breath on his cheek, and gaze at her slightly parted, rose-colored lips. His fingertips trembled. "Open your mouth, please?" His voice was soft, with a hint of gentle persuasion. Elara looked at his face, so close to hers. Her heart gave an inexplicable flutter, but she complied, parting her lips slightly. She thought wearing it would be no more than having something in her mouth, nothing significant. Lin Chen carefully placed the soft silicone sphere into her mouth, positioning it between her upper and lower teeth. Then, he brought the elastic straps around the back of her head and gently fastened the clasp. Once it was secured, he took a step back and looked at Elara. His breath hitched. The gag forced her mouth into a slight, open position. Her rose-colored lips were pressed tightly against the smooth silicone sphere, unable to close or even fully seal. Her cheeks were slightly puffed out, and her usually cool, radiant features now held a touch of vulnerable helplessness, a stark contrast to her usual aloof demeanor. Elara tried to move her mouth. It didn't hurt. The silicone was soft, and it didn't press uncomfortably against her gums. Apart from being unable to close her mouth, there seemed to be no other sensation. She couldn't help but scoff inwardly. *This is it? This is what he was so secretive about?* She wanted to speak, to tease him, but as soon as she tried to exert force, she realized her mouth was held firmly in place by the gag. She couldn't form coherent words, only muffled "mmph" sounds. Just then, something even more humiliating happened. Because her mouth was held open and unable to close, saliva began to secrete uncontrollably. At first, it was just a little, and she could manage to swallow it. But soon, her saliva accumulated, flowing over the edges of the silicone gag and spilling from the corners of her mouth. Crystal-clear saliva trickled down her jawline, dripping onto her elegantly curved collarbone, then sliding down her neckline and into her clothes. Elara's mind went blank, a deafening roar filling her ears. In all her life, she had never been so utterly disheveled! She had always maintained an aura of cool detachment, warding off all admirers, always composed and in control. But now, she was bound by tape by a human she had just met, a gag in her mouth, saliva uncontrollably flowing down her chin, unable to utter a single coherent word, only emitting muffled whimpers. She thought it was something formidable, but it was just a little vibrating toy. She was taped up, gagged, but it was just a small thing on her body, what could be the big deal? If she refused now, wouldn't it make her look scared? She bit down on the gag in her mouth, braced herself, and looked up at Lin Chen, her chin slightly raised. Even though she was bound and unable to move, gagged with her mouth watering, she stubbornly maintained a condescending air, letting out a provocative "Mmmph," and even actively lifted her taped-together legs slightly, as if urging him on. Lin Chen's heart skipped a beat, and his eyes instantly lit up. He had originally thought that Elara would get angry when she heard this, that she would shake her head desperately for him to take it away. He hadn't expected her to agree at all. After all, the gag had already made her so ashamed, and this vibrator was even more intimate and excessive than the gag. He steadied himself, carefully took the pale pink vibrator out of the box, his fingertips touching the cool, smooth silicone surface, his knuckles trembling slightly. He first pressed the plus button on the remote, and the vibrator emitted a very faint, almost inaudible hum. After confirming it was working, he immediately pressed the minus button to turn it off. After doing all this, he looked up at Elara and asked softly, "I, I can start?" Elara turned her face away, not looking at him, and only let out an impatient "Mmmph," which was considered agreement. However, her slightly tensed shoulders and the deepening blush on her ear tips betrayed her nervousness. Lin Chen's heart felt like it was being squeezed by a soft hand, a mix of ache and numbness. Lin Chen crouched down, his fingertips pinching the small vibrator, his knuckles turning white with tension. He didn't dare to let his gaze linger too long, only focusing on the outside of her thighs, tightly bound by tape. Through the thin fabric of her light blue leggings, he gently pressed the vibrator against her. Then he turned it on to the lowest setting, the faint hum almost drowned out by their breathing. Elara's body stiffened abruptly. Her legs, which had been tensed, instinctively wanted to curl up, but they were firmly secured by the tape, leaving her only able to remain rigid. The unfamiliar vibration seeped through the fabric into her skin, a tingling sensation shooting through her nerves and throughout her body, completely different from the mental energy that usually permeated her entire being and surroundings. She was somewhat taken aback. The vibration was stranger than she had imagined. It wasn't painful, but a strange, unprecedented tingling that spread from the point of contact, making her toes curl inside her boots. Her previous disdain turned into panic. She wanted to glare at Lin Chen, but due to the strangeness of her body, her gaze softened, becoming misty. Lin Chen's heart pounded wildly, his eyes fixed on Elara's expression, afraid of any discomfort or hint of disgust from her. His finger hovered over the remote, ready to turn it off at any moment. Seeing her helplessness, bound and gagged, and hearing her occasional gasps of pleasure caused by the vibrator's vibrations, he found it difficult to suppress his own desires. But he maintained his focus and respect for Elara, occasionally murmuring softly, "If you're uncomfortable, shake your head, and I'll turn it off immediately..." The gag prevented her from making any sound, only allowing her to emit soft "Mmmph-wooo" noises. They were no longer the angry sounds from before, but soft whimpers. Her cheeks grew redder, the blush on her neck spreading to her collarbone, and her body trembled slightly. The force with which she leaned against the wall lessened, and she slid down slightly, her once straight back curving into a delicate arc. Shame surged through her, but there was no disgust. Because she could feel Lin Chen's nervousness and lack of malice through their contract, that kind spiritual energy enveloped her, even though it was mixed with some impure lust... But she did feel a strange sense of being carefully cherished, and even a faint sweetness bloomed in her heart. She began to stop forcing herself, her gaze shifting from a glare to a moist plea, tinged with bewilderment. Seeing that she didn't shake her head, only trembled, Lin Chen felt a little relieved. He watched as the girl before him gradually adapted to the frequency, her body's reactions no longer as pronounced. After a period of internal struggle, he finally pressed the remote. The vibrating sensation suddenly intensified, and Elara's body trembled uncontrollably. Her legs were bound and she couldn't move, so she could only let the sensation spread. Drool flowed more profusely from the corners of her mouth, her whimpers became intermittent, and the tears in the corners of her eyes finally couldn't be held back, rolling down her cheeks. Lin Chen saw her cry and immediately panicked, turning off the vibrator. After calming down, he felt through their contract that she wasn't sad, but embarrassed. Only then did he steady his hand, reach out, and gently wipe away her tears, his movements soft. "Don't cry... Can I turn up the setting?" He was somewhat incoherent, because he had only fantasized about dating before, and now that he had made a girl cry, he was naturally flustered. Elara's body trembled at his touch as he wiped her tears, her whimpers softening. She obediently nodded, no longer struggling, allowing him to touch her. Her previously cool demeanor had completely dissipated, replaced by a soft, dependent appearance. The sapphire earrings on her earlobes dangled in the light, accentuating the blush on her cheeks. Elara completely let down her guard. Although he had this... strange fetish, and like other men, harbored lustful desires; she didn't feel disgusted. Instead, she felt a different kind of peace. She was used to pretending to be strong, but unexpectedly showed her vulnerability in front of a newly formed man. And this man, though somewhat introverted and timid, had disarmed her pretense in this way. She could completely understand his desire for her, but she considered it "human nature." What mattered more to her was "how he did it." Compared to the falseness layered in the appearances and words of others, the respect this young man showed her in his words, his training, and the signing of their contract, his direct and unpretentious requests, gave her a good initial impression—at least she didn't have to worry about this contract bringing her danger. Seeing her soften, Lin Chen's inner desire was satisfied, but more than that, he felt heartache and joy. So she too had such a vulnerable side. He tightened his grip on the remote, not daring to increase the intensity, maintaining only the slightest vibration, quietly watching her, his eyes filled with adoration and cherish. The contract mark on his wrist burned. "Alright, it's about time I untied you." Although reluctant, Lin Chen did not hesitate to begin helping Elara undo her restraints. As he untied her, he kept glancing at Elara's eyes, which seemed to hold more than just dislike. "Hmph, I'll indulge you this once, don't think about it again, lit— no, Lin Chen!" After removing the gag, her words were slightly slurred, but she didn't hide her protest. Those tsundere and slightly hoarse words were a supreme pleasure to Lin Chen's ears. Suddenly, the infinite power within Lin Chen gradually dissipated, while Elara became smug. "Forget it, it's fine to play with you next time!" she said softly, her face flushed. After saying it, she regretted it, her face burning even more. She didn't know why she said that, especially after being so thoroughly dominated just now. But the surge of ecstatic joy from Lin Chen through their contract made the corners of her lips curl up. Hearing that there would be opportunities for him to "train" her again, Lin Chen's previously calmed emotions stirred once more. However, he forced himself to remain calm. "Whether we play next time or not, let's sleep first. I've prepared a room for you..." Elara rolled her eyes and gave a playful smile. "Don't you know? You can use cultivation instead of sleep, and I can rest in your contract space. Goodbye!" Her words shattered Lin Chen's fantasy of living with a girl. Watching the girl disappear before him, he sighed and sat alone on the bed, fumbling with methods of cultivation. While cultivating, he also couldn't help but fantasize about Elara's promise just now. Next time, he would learn to bind her with ropes! "What else could it be?" Elvira straightened up, walking towards him step by step, her boots clicking crisply on the bluestone. She leaned in slightly, her emerald eyes close to his, her tone laced with teasing, "Sensing that little imp's spiritual energy was flagging, I was worried you'd get sick from being alone, so I came out to stroll with you. Is that not allowed?" As she spoke, she reached out as if to ruffle his hair, her gesture natural and intimate. Lin Chen's heart skipped a beat, the lingering insecurity suddenly swept away by a surge of unexpected courage. He instinctively took half a step back, his hand darting into his pocket, clutching the cool metal object. His fingertips trembled slightly with nervousness as he said, with a hint of surprise, "It's not that it's not allowed... I have something new here, I want you to try." Elvira raised an eyebrow, her brow arching, her eyes full of curiosity. "Something new? What bizarre contraption have you cooked up this time?" She assumed it was something like the ropes again, a secret flicker of anticipation stirring within her, yet she maintained her cool demeanor, waiting for him to reveal it. Lin Chen took a deep breath and pulled out the pair of silver metal handcuffs from his pocket. He had specifically chosen a rounded-edge model, with no sharp angles to dig into the skin. The clasp was adjustable, allowing for control over the tightness. He had kept them hidden in his pocket for days, waiting for this very moment. The coolness of the metal glinted faintly in the sunlight, the small handcuffs resting in his palm, looking remarkably conspicuous. Elvira's gaze fell upon the handcuffs. Her emerald irises first registered surprise, then a clear disdain. Her eyebrows rose even higher, a sneer playing on her lips, her tone dripping with almost palpable disgust. "Imp, your taste is truly abysmal. At least the ropes showed some effort. What's the point of this piece of scrap metal?" In her opinion, this cold metal object was far inferior to the ropes. It lacked the tactile sensation of being bound and appeared remarkably crude, offering nothing worth exploring. Despite her verbal disdain, she didn't retreat or refuse. She simply crossed her arms, her cool gaze fixed on him, the contempt in her eyes as clear as day, as if to say, "Only you would find something like this appealing." This outwardly dismissive yet inwardly compliant attitude made Lin Chen's heart beat faster, but also solidified his resolve. He moved behind Elvira, his voice low. "I've already smoothed them down. They won't dig into your skin. I'll adjust the tightness, and you can tell me immediately if it's uncomfortable, and I'll unlock them." Elvira scoffed but remained silent. Instead, she obediently placed her hands behind her back, fingers interlaced, just as she had done when he tied her with the ropes. She even subtly adjusted her wrists to make it easier for him. Her back remained ramrod straight, her posture exuding a cool pride even in this submissive pose. However, a faint, almost imperceptible blush on the tips of her ears betrayed her nervousness. Lin Chen's fingertips brushed against her cool wrists, her skin smooth and delicate. His fingertips trembled slightly as he carefully placed each cuff around her left and right wrists, then gently fastened the clasp. He had deliberately set it to the loosest setting, ensuring a slight gap between the handcuffs and her wrists, so they wouldn't feel constricting. The cold metal pressed against her wrists, imparting a firm and distinct sense of restraint. Unlike the gentle embrace of the ropes or the encompassing feel of tape, this restraint was more direct, making her feel more acutely that her control over her body was being relinquished. Elvira's wrists moved slightly, the handcuffs emitting a soft "click." Her hands were now securely fastened behind her back, rendering her immobile. Lin Chen looked at her hands cuffed behind her back. The silver handcuffs stood out starkly against her light blue form-fitting attire. He quickly took off his black hooded jacket and carefully draped it over her shoulders. The jacket's length reached just above her thighs, completely concealing her cuffed hands, revealing only the edges of her wrists. The sleeves of the jacket slipped over her arms, and the collar gently framed her neck, obscuring her collarbones. His fingers brushed against her shoulders and back with a gentleness that suggested he was afraid of hurting her. The warmth of his fingertips seeped through the thin fabric of her attire, reaching Elvira's skin and causing her body to tremble slightly. "There," Lin Chen said, moving to her side. His gaze fell on her back, hidden by the jacket. A sense of control and secret joy mingled within him, along with a touch of nervousness, fearing they might be noticed by passersby. Elvira tugged at the jacket, shifting her body with a hint of awkwardness. With her hands cuffed behind her, her back was naturally held straighter, and her gait became unconsciously a little stiff. She glanced sideways at Lin Chen, her emerald eyes still holding a trace of disdain, and grumbled, "This is so bothersome, wearing a jacket is making me sweat." Yet, she didn't remove it. She simply lifted her foot and started walking. "Let's go, weren't we going shopping? Stop dawdling." Lin Chen quickly followed, walking beside her, deliberately slowing his pace to match hers. He leaned slightly towards her, one hand gently supporting her arm, fearing she might stumble due to the inconvenience of having her hands cuffed behind her. His fingertips brushed against her cool arm, his cheeks flushing slightly, but he didn't let go, steadying her. This was their first time shopping together in this manner. The handcuffs hidden beneath the jacket forged a connection between them that was both secret and profound. Lin Chen walked beside her, occasionally glancing at her, and quietly asking, "Would you like a cup of herbal tea? The tea at that elven tea shop up ahead is quite good." "Are you tired? Shall we find a place to sit for a while?" "Those elven honey cakes on the street look delicious, would you like to try one?" Elvira was initially a little awkward. With her hands cuffed behind her, she couldn't even lift a hand to adjust her hair, leaving her light blue strands to fall over her shoulders. However, with Lin Chen's careful attention, her awkwardness gradually dissipated, replaced by a faint sense of novelty. She still complained verbally, "What tea, it's too sweet," and "We've only walked a few steps, how could I be tired," but she followed his lead. When she saw the light blue hydrangeas displayed at the entrance of the tea shop, she subtly gestured with her eyes. Lin Chen, understanding her unspoken wish, led her into the shop and ordered a cup of the clear herbal tea she favored. Since Elvira's hands were cuffed, Lin Chen had to hold the teacup and lean in slightly, bringing the rim to her lips. He said softly, "Be careful, it's a bit hot." Elvira lowered her head slightly, her lips touching the cool rim of the cup and taking a sip. The clear, refreshing tea aroma spread in her mouth. The tips of her ears flushed a faint pink, and her gaze fell on Lin Chen's reddened cheeks. A hint of a smile flickered in her emerald eyes, but she deliberately turned her head away. "It's just okay, not as good as the elven realm's." Lin Chen didn't argue. He simply smiled and placed the teacup aside, then went to buy an elven honey cake. He picked up a small piece with a tiny fork and offered it to her lips. The sweet aroma of the honey cake mingled with the refreshing scent of herbs. Elvira opened her mouth and bit down. The sweet syrup melted in her mouth, rich but not cloying. Her tongue inadvertently brushed against Lin Chen's fingertips, and both of them trembled slightly. Lin Chen's face turned even redder. He quickly withdrew his hand, pretending to look out the window, his heart pounding as if it would shatter his ribs. People bustled by on the street, and no one noticed that the cool elven maiden had her hands cuffed behind her back beneath her jacket. Occasionally, passersby would glance over, merely assuming they were a typical contractor and elf, and cast envious looks at Lin Chen, thinking how fortunate he was to have such a beautiful elven contractor. Lin Chen felt those gazes, and the lingering insecurity within him gradually faded, replaced by a full sense of confidence and a secret joy. Elvira leaned against the window of the tea shop, watching Lin Chen fumbling as he handed her a tissue to wipe the honey syrup from the corner of her mouth, his fingertips brushing her lips. The coldness of the metal handcuffs still pressed against her wrists, the sense of restraint distinct, yet it didn't displease her at all. Instead, it evoked a subtle sense of security. She raised her eyes slightly, looking at Lin Chen's flushed earlobes. The disdain in her eyes had long since vanished, replaced by a gentle tenderness. Yet, she still spoke with her characteristic傲娇 (àojiāo - proud and tsundere): "So clumsy, you can't even wipe your mouth properly." He slowly tightened the hemp rope, his movements so gentle as if afraid to disturb something. Avira's right leg was slowly lifted, about half a foot off the ground, her left leg supporting her body alone, her center of gravity naturally shifting. She subconsciously leaned to the side, her back taut, her waist arching into a beautiful curve. The light blue tight-fitting outfit, pulled by the rope, outlined the clean lines of her legs. The off-white knot at her ankle contrasted with her cold white skin, creating a unique aesthetic. "Does it hurt from the pull?" Lin Chen squatted down, his fingertips lightly touching her lifted calf, his voice extremely soft, his eyes full of concern. Avira's toes tensed slightly, her toes curling inward. There was a slight stretching sensation in her leg, but no pain at all. She tilted her head and glanced at him, her tone proud, "This much force isn't enough to impress me." Lin Chen straightened up and took another piece of rope, gently binding her hands behind her back. The knot fell below her shoulder blades, loose, serving only as a symbolic restraint, fearing she might fall due to imbalance. After doing all this, he picked up the rabbit vibrator from beside the desk. It was pale pink silicone, already charged. He walked in front of her, his fingertips lightly lifting the hem of her outfit, and placed the vibrator against the soft flesh of her inner thigh, where the fabric was thinnest, allowing the vibrations to be clearly transmitted. He pressed the switch, setting it to medium. The subtle hum was almost inaudible, yet it carried a fine tingling sensation that seeped through the fabric into her skin. Avira's body jolted, a wave of numbness shooting up from her tailbone, climbing her spine and enveloping her limbs. Her center of gravity, already off-kilter from being suspended by one leg, shifted further. Her left leg bore her weight, knee slightly bent, while her lifted right leg was straight, her toes instinctively curling. The off-white hemp rope around her ankle left a faint mark on her cold white skin, yet there was no pain. Her hands, bound behind her back, clenched slightly, her fingertips digging into her palms. Her back arched into a slender yet supple curve, her waist bending slightly to the left due to the imbalance. The light blue outfit clung to her skin, accentuating the lines of her waist and hips even more. The fine tingling spread from her inner thigh, intertwining with the slight stretching sensation in her leg, causing her breathing to falter. A soft groan escaped her nostrils, her emerald pupils narrowing slightly, a faint blush creeping into the corners of her eyes. She felt powerless, unable to even break free from these light knots, left to Lin Chen's will. Lin Chen watched her trembling shoulders, his fingertips gently resting on her waist, steadying her, fearing she might fall. His palm touched her slightly cool skin, feeling the subtle tremors of her body. His Adam's apple bobbed. "Shall I put in the gag? It's medical-grade silicone, won't hurt your mouth." His voice was as soft as melted sugar, a request, not a demand. Avira tilted her head to look at him, the blush on her cheeks deepening. She pursed her lips and finally nodded gently, a silent consent. Lin Chen picked up the soft silicone dildo gag from the box. The pearly white silicone gleamed with a soft light. He held the gag between his fingertips and walked in front of her, saying softly, "Open your mouth, slowly, don't bite your tongue." Avira slightly raised her chin, slowly parting her lips, the rose-colored curves forming a beautiful arc. Lin Chen carefully placed the gag into her mouth, fitting it snugly between her teeth, then gently fastened the buckle behind her head. The tightness was adjusted just right, not constricting, but holding it firmly in place. The tip of the dildo pressed against her lips, the pearly white silicone contrasting with her pale pink lips, creating an intensely intimate scene. Avira tried to move her mouth. The soft ball was comfortable, with no discomfort. However, her mouth was propped open and couldn't close. Saliva quickly began to accumulate in her mouth, spilling over the edges. Crystal clear drool trickled down her jawline, dripping onto the back of Lin Chen's hand as he steadied her waist. The warm touch sent a tremor through his fingertips. A wave of intense shame washed over Avira. Her face instantly turned crimson, from her cheeks to the roots of her ears, and down her neck, all flushed with an alluring scarlet. Her emerald pupils were clouded with moisture. She glared fiercely at Lin Chen, but could only emit muffled "woo woo" sounds, each whimper carrying a subtle tremor, made even softer by the hum of the vibrator. She wanted to turn her head away, but Lin Chen's hand firmly held her waist, rendering her immobile. She could only watch as saliva slowly slid down the silicone surface of the dildo, wetting the light blue outfit on her chest, creating a small, damp patch. It then flowed down the curve of her waist into Lin Chen's palm. The warm wetness mixed with her cool skin, making Lin Chen's palm tingle, and a fine itch spread through his heart. Avira's left leg was already trembling from supporting her body alone, her knee involuntarily bending. Her right leg, suspended by the rope, was stretched straight, the sole of her foot slightly arched, her toes tightly curled. The off-white knot at her ankle had dug into her cold white skin, leaving a faint pink mark, yet there was no pain. Her hands, bound behind her back, clenched even tighter, her knuckles turning pale. Her back arched into a slender yet supple curve, her waist bending slightly to the left due to the imbalance, the lines of her waist and hips accentuated by the tight outfit becoming even more alluring. The medium vibration of the vibrator continued to spread its fine tingling sensation, creeping from her inner thigh towards her lower abdomen, intertwining with the stretching sensation in her leg, making her breathing more rapid. The whimpers escaping her nostrils were muffled by the gag, breaking into soft "woo woo" sounds. In her emerald pupils, fine tears finally couldn't be held back and rolled down, mixing with the drool trickling down her jawline, dripping onto Lin Chen's hand. The warm wetness, coupled with the cool touch, made his heart skip a beat. Lin Chen's fingertips still held a faint mist of ice, an ice-elemental superpower temporarily lent to him by Avira, dancing on his palm, cool but not biting. He lowered his head, looking at the sole of Avira's lifted right foot. The skin there was cold, white, and delicate. The sole of her foot was slightly arched, her toes tightly curled, even the lines of her sole stretched taut, clearly indicating an extremely sensitive area. His Adam's apple bobbed. He leaned close to her ear, his voice so soft it could drip, with a cautious request, "Can I touch your sole with ice? Gently, just a brush. If it's uncomfortable, shake your head, and I'll stop immediately." She didn't shake her head. Instead, a soft, delicate whimper escaped her throat, blocked by the gag. Her emerald pupils were moist as she looked at him, the blush on her eyelids extending to her temples. Her left leg, supporting her body alone, was already trembling slightly, her knee bending more, yet she still stubbornly held on, as if in silent agreement. Lin Chen steadily supported Avira's waist, his palm pressed against her cool skin. With his other hand, he gently raised his fingertips, condensing a tiny, wafer-thin shard of ice. The ice particle was so small it was almost invisible. He carefully brought his fingertip to the sole of her right foot and gently brushed it. The coolness of the ice instantly touched her warm, delicate skin, like an electric current that shot through Avira's nerves. "Mmm—!" Avira's body suddenly tensed, her back arching sharply, her waist forming a breathtaking curve. Her right leg, suspended by the rope, instantly straightened, her toes curling forcefully. The skin on the sole of her foot, stimulated by the ice, recoiled sharply, her toes curling into a bow shape. The cool stimulation exploded from the sole of her foot, traveling up her calf along the hemp rope at her ankle, and then entwining with the tingling sensation in her inner thigh. It collided with the fine, numbing vibrations of the vibrator, transforming into a more surging current that coursed through her entire body. The fine vibrations of the vibrator continued to spread in her inner thigh, colliding head-on with the unexpected cool stimulation on the sole of her foot. Two entirely different sensations twisted into a surging wave that coursed through Avira's limbs. The strength of her left leg supporting her body grew increasingly unstable, her knee bending into a shallow arc, a faint ache spreading from her hip. Her right leg, suspended by the rope, was stretched straight, the off-white hemp knot at her ankle sinking into her cold white skin, leaving a faint rosy imprint. The sole of her foot, stimulated by the ice, curled tightly, even the lines of her sole stretched taut and clearly visible. He knew he had neglected her for the past half month, and guilt filled his heart. Just as he was about to apologize, Elvira reached out and pressed her fingers to his lips. Her fingertips were cool, pressing against his lips with a faint hint of moisture. Her voice was soft, yet laced with a hint of provocation: "I heard you humans have many fun ways to relieve stress. I specifically looked it up and learned some new things. Want to try?" Under her gaze, his stress and fatigue melted away, replaced by a stirring desire. He nodded, "I'll do whatever you say." Elvira smiled, taking his wrist and leading him to the bedroom. As if familiar with every step, she seemed to set the rhythm, making Lin Chen's earlobes flush crimson. He obediently walked to the bedside and picked up the pre-prepared hemp rope. It was Elvira who initiated, turning to face away from him and standing still. She clasped her hands gently behind her back, fingers intertwined. Her milky white bodysuit accentuated the delicate curve of her spine, and her legs, encased in white stockings, were pressed together. She stood on tiptoe, like a flower waiting to bloom. "Four-legged tie, right?" she said with a hint of amusement. "You've wanted to tie this for a long time, haven't you?" Lin Chen felt his heart pounding in his chest. He hadn't expected her to know this. With trembling fingers, he held the hemp rope and walked behind her. The rope, cool to the touch, began to wrap around her wrists. He controlled the tension perfectly, tightening it firmly but without digging into her flesh, securely binding her hands behind her back. Then, she willingly lay down on the bed. He bent down, gently lifting her ankles. The rope wound around her ankles and then up her calves, pulling her legs back to be securely tied to her wrists, forming a standard four-legged tie. The moment she was bound, Elvira's body tilted slightly forward, forcing her to support herself on her knees and chest. Her back arched into a beautiful, soft curve. Her milky white bodysuit clung to her skin, accentuating her waist and hip curves to a breathtaking degree. Her legs, encased in white stockings, bent backward, toes pointed, giving her porcelain-like skin a subtle sheen beneath the fabric. She tried to move, but her body was held fast, unable to even offer the slightest struggle. "Is it tight?" Lin Chen crouched beside her, his fingertips lightly touching her ankle. Elvira giggled, her laughter soft and sweet, drifting into Lin Chen's ears along the folds of the sheets, tickling him with its allure. "Silly boy, just say you want to relax. I'm not going to refuse you." She turned her head, her emerald eyes glistening. "Take it out. Stop dawdling. We can do whatever you want." Lin Chen's heart rate suddenly quickened. He got up and walked to his desk, opening the bottom drawer. He took out the silicone vibrator and a small jar of lubricant – he had sterilized it beforehand and wiped it clean. Now, holding them in his hand, Lin Chen's fingers trembled slightly. He walked back to the bed with the vibrator and lubricant. The warm yellow light fell on Elvira, the four-legged tie creating a graceful curve in her back. Her milky white bodysuit stretched taut over her waist and hips, her white-stockinged legs bent backward, her ankles and wrists bound together. Her small feet were pointed, the tips of her toes beneath the stockings glowing with a faint pink hue, like soft jade. He unscrewed the lubricant, dipped a fingertip in it, and let the cool liquid glide over the vibrator's surface. He then carefully brought it to Elvira's side. The leg of her bodysuit had a subtle opening, and he gently inserted the vibrator, turning it on to the lowest setting. A faint hum immediately filled the air. Elvira's body jolted, her nose pressing into the sheets, and the movement paused. A soft groan escaped her throat. Her emerald eyes narrowed slightly, the corners of her eyes instantly flushing a faint pink. "Is that all the power you have?" she challenged, her voice feigning toughness. Lin Chen looked at her pointed toes, clearly seeing the curve of her toes curling inward. He tentatively extended a finger and gently brushed her sole. The warmth of his fingertip transmitted through the stocking, and Elvira's body trembled violently, as if struck by an electric current. The soft groan in her throat turned into a series of faint whimpers. "Lin Chen... don't touch there... it tickles..." She tried to pull away, but the four-legged tie rendered her immobile. She could only let his fingertip caress her sole, moving from the arch to the base of her toes, inch by inch. The vibrator's vibration continued to ripple within her, the fine tingling sensation mixing with the ticklishness of her sole, shooting through her nerves and spreading throughout her body. Her toes curled frantically beneath the stocking, their tips brushing against the rope, yet unable to escape that warm touch. Lin Chen watched her flushed earlobes and listened to her soft whimpers. The stress of the past few days seemed to have found an outlet. He gently increased the vibrator's setting, and the vibration instantly intensified. He then used his fingertip to lightly scratch her sole, his movements not heavy, but precisely targeting the most sensitive lines. Elvira's body began to tremble uncontrollably, her back arching and relaxing intermittently. Her milky white bodysuit clung to her skin with her movements, revealing even clearer curves. Her whimpers grew louder, mixed with soft, breathless laughter. "It tickles... stop scratching... the vibration inside... it's too much..." The intense vibration of the vibrator, combined with the tingling pleasure on her soles, wove into a surging wave within Elvira's body. Her breathing grew more rapid, her whimpers turning into soft, breathless moans. The numbness in her body intensified, even her fingertips began to tingle. The bottle of water she had deliberately drunk earlier quickly turned into urine, filling her bladder. The unbearable sense of nearing her limit made her cry out even more fiercely. Finally, a stream of warmth uncontrollably gushed out, seeping through the milky white bodysuit and staining a small patch of fabric. Elvira's body froze for a moment, then completely softened. She buried her face in the sheets, her earlobes burning crimson, her voice choked with embarrassed tears. "Lin Chen... I..." She knew clearly that she had lost control of her bladder, and that she had even caused it herself. Lin Chen's fingers paused. He looked at the wet patch, his eyes devoid of any disgust. He reached out and stopped the vibrator, but did not immediately untie the ropes. He simply gently caressed her ankle. The tension in his mind, built up over days, began to relax. All his anxiety, fatigue, and stress dissipated little by little with her breathless moans and whimpers. He knew this wasn't purely driven by her desire; it was more her deliberate choice to lose control and offer herself for his pleasure and his peculiar tastes. Lin Chen carefully untied the knots of the four-legged tie. The moment the ropes loosened, Elvira's body slumped softly into his arms. Her cheeks were hot, and she buried her face in his neck, her voice hoarse and soft. "It's all your fault... making me like this..." Lin Chen gently held her, his fingertip brushing over the dampness on her body. "I'm sorry for making you ashamed; and thank you for trusting me, for being willing to show me this side of yourself." But his voice... Lin Chen carefully held her soft body, his fingertips gently tracing the faint red marks left by the rope. The milky white bodysuit, damp with urine, clung to her skin with a cool stickiness, yet it didn't make him feel disgusted in the slightest. Instead, his heart was filled with tenderness. He didn't know what to say, but he knew that such a proud girl had deliberately shown him her most shameful self, all for his relaxation and his preferences. Lin Chen's eyes lit up instantly, and he nodded quickly, but then frowned again: "But... the simulation field is full of contractors and elf partners entering. If you go with me, I will always subconsciously rely on you and won't be able to practice my control at all." Avila raised an eyebrow, clearly having already thought of a solution. That night, back at the rented apartment, warm yellow light filled the desk. Avila reached out, pulled open a drawer, and took out the soft hemp rope mixed with moonpetal fluff. Beside it lay the familiar silicone gag and the bullet vibrator. Seeing these items, Lin Chen's cheeks instantly turned red, and he waved his hands in a panic: "But... how can this be?!" He stepped forward, wanting to close the drawer, "This is for practicing combat skills, how can you let you..." "Why not?" Avila raised her hand and pressed on his wrist. Her fingertips were cool, but her grip was undeniable. Her emerald pupils stared directly at him, her tone carrying its usual certainty, "Your biggest problem isn't a lack of strength, it's a scattered focus. In actual combat, you always think of relying on me, and you can't even concentrate your mental power." She turned her hand and opened the drawer again, taking the soft hemp rope in her hand. Her fingertips brushed across the rope, her tone softening slightly, but still carrying an irrefutable dominance, "I'll tie myself up and seal myself in the contract space, cutting off all your avenues of reliance. You'll have to rely on yourself to control your ice abilities. At the same time, with my power, your control over ice abilities will temporarily strengthen; I can also use the contract to precisely capture every trace of your scattered mental energy and guide you with my own sensations." Lin Chen's Adam's apple bobbed. He felt flustered and warm at the same time. He opened his mouth to retort but couldn't find a single suitable word. He knew Avila was right. Every time they practiced in real combat, as long as Avila was around, he would subconsciously hold back, always feeling that even if he lost control, she would be there to catch him. He could never truly develop his own control. But the thought of tying her up, gagging her, and even placing the vibrator on her, sealing her in a contract space meant for only her, filled him with unbearable pain and a hint of undisguised panic. "But... if you're alone in there and uncomfortable, what will you do? I won't be able to stop and take care of you at any time." "Silly boy." Avila couldn't help but chuckle, reaching out to gently pinch his reddened earlobe. "The tying method is one you've practiced hundreds of times. You can control the tightness, and the gag is made of soft silicone. I'll only turn the vibrator on the lowest setting. What could be uncomfortable?" "Besides, the contract binds us both. If anything really happens, I can withdraw my power through you. What could go wrong?" Avila's fingertip lightly traced the contract mark on his wrist, a faint blue light rippling along her fingertip. The teasing in her tone faded slightly, replaced by an undeniable seriousness. "Or, would you rather always hide behind me, and then at the assessment, in front of the entire grade, you can't even defeat a low-level monster?" This sentence hit Lin Chen's soft spot precisely. He clenched his fists, his fingertips turning slightly white. Looking at the determined light in Avila's eyes, he finally gritted his teeth and nodded. "Okay... I'll listen to you. But if you feel even the slightest discomfort, even just a little bit, I'll immediately terminate the assessment and come back to untie you. I won't delay for a second." "Got it, you nag." Avila scoffed, but the tips of her ears quietly turned a faint pink. She actively turned around, standing with her back to Lin Chen. She pushed her long, pale blue hair forward over her shoulders, revealing the slender, graceful lines of her neck and shoulders. She clasped her hands behind her back obediently, just as she had countless times before. "Start, use the Hojojutsu you're most familiar with. Tie it tight, so that if I move even a little in the contract space, the knot doesn't loosen and distract you." Lin Chen took a deep breath, suppressing the surging emotions in his heart, and picked up the hemp rope from the desk. The moment his fingertips touched the smooth rope, his movements instantly steadied. Just like the hundreds of times he had practiced, the hemp rope first wrapped around her neck and shoulders, passed under her collarbone, and then tightened in circles along the curve of her waist, forming neat diamond patterns in front of and behind her. His movements were still cautious. After every two wraps, he would stop and probe the tightness with his fingertips, ensuring that a finger could easily slip through before continuing. The hemp rope continued down her waist to her hips, then looped back behind her, securely fastening her wrists, which were clasped together. The knot for the rear-hand bondage was tight but not rigid, firmly locking her arms behind her, making it difficult to even move her fingertips. "Is it tight?" Lin Chen leaned close to her ear, his voice kept very low. His warm breath brushed against her earlobe, and he could clearly see the blush on her earlobe deepen instantly. "It's okay." Avila's voice had a barely perceptible huskiness, but her back remained perfectly straight. Even bound tightly by the rope, she still possessed that innate pride. "Don't dawdle. There are still things to put on, weren't they prepared long ago?" Lin Chen's cheeks flushed a few shades deeper. He reached out and picked up the silicone gag from the desk. He walked in front of Avila, looking at her slightly flushed cheeks. His fingertips gently caressed her lips, his voice soft enough to drip water. "Open your mouth, okay? If it's uncomfortable, just nod, and I'll take it off immediately." Avila glared at him but obediently parted her rose-colored lips slightly. Lin Chen carefully placed the soft silicone ball into her mouth, fitting it snugly between her upper and lower teeth. Then, he wrapped the elastic straps around the back of her head and gently fastened the buckle, adjusting the tightness just right so it wouldn't make her jaw ache, but would hold it securely in place. The moment the gag was in place, Avila tried to move her mouth. She could only make muffled "woo woo" sounds. Saliva quickly began to secrete in her mouth, and a trickle of clear drool seeped from the corners of her mouth along the edge of the silicone ball. A wave of intense shame instantly washed over her, from the tips of her ears to her neck. She glared fiercely at Lin Chen but could only emit soft, whimpering sounds. Seeing her like this, Lin Chen felt a mix of tenderness and a bittersweet ache. He reached out and gently wiped away the trickle of drool from the corner of her mouth. His Adam's apple bobbed, and his voice dropped to a low murmur, "I'm sorry to trouble you." Avila glared at him fiercely, emitting muffled "woo woo" sounds from her mouth, as if scolding him for being useless. He took a deep breath, picked up the pale pink bullet vibrator from the desk, and pressed the power button to confirm the very faint hum. Then, he squatted down, looking up at Avila, seeking her consent with his eyes. Avila turned her face away, the blush on her earlobes already spreading to her jawline. However, she subtly brought her legs together, as if silently agreeing. Lin Chen's fingertips trembled slightly. Through her form-fitting athletic pants, he gently placed the vibrator on the most sensitive spot on her inner thigh, secured it with tape, and pressed the lowest setting. A fine vibration instantly began, so faint it was almost drowned out by their breathing. Yet, Avila's body trembled violently, her spine instantly stiffening. Her arms, tightly bound by the rope, instinctively tightened, her fingers clenching into fists. A faint whimper escaped her throat, her eyes growing more watery, but she stubbornly bit down on the gag, refusing to show any sign of weakness. Lin Chen's fingertip lightly pressed the edge of the tape, confirming the vibrator was securely in place. He then straightened up, reached out, and placed his hand over the contract mark on Avila's wrist, saying in a deep voice, "Power transfer, I'm counting on you." Avila nodded slightly, her fingertip touching the contract mark. Pale blue and warm golden light suddenly intertwined. Cool ice-elemental power surged into Lin Chen's limbs through the mark, while the light around her slowly faded. Her body swayed gently, and Lin Chen steadied her.
