The Strongest Restraint System

"System ready." A mechanical voice entered Zhao Yuhan's ears. Zhao Yuhan opened her eyes, and the familiar four options floated before her. 1. Restraint Mode 2. Points Store 3. Personal Information 4. Exit System It was the same as the last time she opened it, which made Zhao Yuhan breathe a sigh of relief. This was only the second time Zhao Yuhan had opened this system. "Open the Points Store." "Dear LV1 customer, your current points balance is 0. The options you can operate are: 1. Redeem for cash. The ratio is 1 to 400. 2. Upgrade to LV2, costing 50 points." "Can this system... really give me cash...?" This was why Zhao Yuhan wanted to try. Although the card was quite suspicious, with such an easy way to make money, Zhao Yuhan decided to give it a try. "Whatever, I'll try it first. Open Restraint Mode!" "Please select a package. The packages you can currently choose from are: Package A: Lasts 10 minutes, earns 1 point. Package B: Lasts 1 hour, earns 10 points. Package C: Lasts 2 hours, earns 50 points." "50 points! That's twenty thousand yuan, isn't it??" "Package selected, restraint system, initiating now." The card on the table suddenly flew into the air. This time, the card emitted a strong light again, enveloping the entire room. "W-w-where are my clothes??" In an instant, Zhao Yuhan's clothes were stripped off, revealing her graceful body. Her slender figure made her small breasts appear exceptionally perky. The moment she realized something was wrong, Zhao Yuhan immediately covered her chest with her hands. "Space confirmed, space lockdown complete. Props prepared, initiating restraint." "Wait?! What is this situ—" Before she could finish speaking, Zhao Yuhan felt something being stuffed into her mouth, abruptly cutting off her words. At the same time, a rope emitting a blue light quickly weaved around Zhao Yuhan's body. Before Zhao Yuhan could react, she found herself on the ground, completely unable to move. Zhao Yuhan struggled frantically, but the rope on her body remained motionless, bound to her skin. The ropes connecting the middle sections of her limbs were continuously tightening, causing Zhao Yuhan's waist to bend backward. "Mmmph mmmph mmmph...!" Forced to bend over, Zhao Yuhan let out a pained sound, but her mouth was gagged, and she could only emit whimpering cries. Fortunately, as if reaching the limit of her body, the rope finally stopped tightening. It seemed the entire restraint process was over. At this moment, Zhao Yuhan's posture was like a ripe shrimp, her hands and feet bound tightly behind her. This binding method was undoubtedly a horse-fetter. "Restraint process complete, timing begins now, countdown fifteen minutes." After exhausting her strength and realizing she was completely immobilized, Zhao Yuhan finally stopped struggling. The clock on the wall showed ten minutes had passed, and Zhao Yuhan had finally calmed down. Although her body couldn't move, it seemed to be only that. As long as another five minutes passed, the countdown would end. Wait, fifteen minutes? Not an hour? A sense of foreboding rose in Zhao Yuhan's mind, but at this moment, she could do nothing but stare at the clock on the wall. "Fifteen-minute countdown ended, initiating additional props, intensity set to 2, countdown forty-five minutes."

Zhao Yuhan's face was filled with shock. "You're the first person to call me 'sister,' and the only hopelessly stupid idiot." Chu Mushu's hand exerted a slight force, and Zhao Yuhan was pushed onto the bed. "Let me think, what kind of toys should I use to discipline my little darling today? Ah, this will do." A familiar wicked grin returned to Chu Mushu's face. A latex bodysuit was tossed onto Zhao Yuhan. "Sister... you're not going to touch me?" "Dream on. It's just not time yet." "Sister is so good." "Who was it that called me wicked earlier today? Today's restraint training time will be doubled, then~" "No! Sister, I was wrong!!!" ... As a result, Zhao Yuhan was restrained without any suspense. At this moment, Zhao Yuhan was clad in a black latex bodysuit. The suit only had an opening for the nose to breathe. Her mouth was stuffed with an electric dildo and gagged. Although the feeling of restraint from the latex bodysuit was quite pronounced, it was clear that a single latex bodysuit was far from enough. A large amount of rope bound Zhao Yuhan tightly. Zhao Yuhan was forced to keep her hands raised above her head, wrists cuffed to the headboard. Her legs were tightened by rope loops, held together in a straight, upright position. This was also the time Chu Mushu used the most toys, with almost every sensitive part of Zhao Yuhan's body fitted with various devices. "Mmmph! Mmmph!" The feeling of a foreign object blocking her throat was extremely uncomfortable, but this wasn't the main reason Zhao Yuhan kept whimpering. What truly affected her were the electric butt plug in her rear, the vibrating dildo filling her pussy, and the

"Thank you, Mr. Wei..." Although Zhao Yuhan could still speak normally, her body was trembling uncontrollably. After soaking in the hot spring for so long, the devices on her had been escalated to a medium-high setting, and her gradually rising body temperature had reached a point where she could no longer bear it. Fortunately, Chu Mushu had left her an escape route: the switch. There was no better time than now. Zhao Yuhan directly pressed the switch. The entire dress instantly reverted to its gray-blue state, and Zhao Yuhan's body temperature dropped significantly. Taking advantage of the temporary shutdown of all the devices, Zhao Yuhan immediately tried to swim to the edge of the hot spring. However, she suddenly realized that she couldn't move her legs. The new restraint was a pair of sparkling chain anklets that locked her feet together. Because the chains were so thin, Zhao Yuhan hadn't noticed them at first. "This is bad..." This restraint only limited her mobility, and mobility was precisely what Zhao Yuhan needed most right now. Zhao Yuhan finally managed to drag herself to the edge of the hot spring, having swallowed quite a bit of water in the process. Only then did Zhao Yuhan have the chance to look at the photo Mr. Wei had given her. To her surprise, the photo was a selfie of Chu Mushu. The photo clearly showed Chu Mushu's current location: a famous scenic spot nearby. It was called a scenic spot precisely because it was located at the summit of a mountain. "Sister must have done this on purpose, right?!" Zhao Yuhan was on the verge of cursing. Adding a pair of anklets at this moment was clearly intended to make things difficult for her. Fortunately, at this moment, Parnu also arrived at the edge of the hot spring. Seeing Zhao Yuhan at a loss and observing the changes in her appearance, Parnu understood what had happened. "Did Master find a new clue? Where is this place?" "The nearby mountain summit..." "The summit? But Master, you're wearing anklets now... How are you going to get there?"

In an instant, Zhao Yuhan's clothes were stripped away, leaving her completely naked. Fortunately, the ropes didn't appear immediately this time. A strong light emanated from the black card, and when the light dissipated, a wooden hobby horse appeared before Zhao Yuhan. "This is... the randomly selected item this time?" She hadn't expected something so large, no wonder it consumed so many points. "You must use the item within 30 seconds, or the punishment program will be executed." "Use it? This big thing... do I have to ride it?" Zhao Yuhan swallowed. The horse's back was a triangular corner, and she didn't even need to guess what would happen when she rode it. But Zhao Yuhan seemed to have no right to refuse; she didn't want to face any punishment program for no reason. The hobby horse wasn't very tall, and Zhao Yuhan could just manage to straddle it. However, the moment her full weight pressed down on her split, she felt a distinct pain, forcing her to grip the horse's head with both hands to distribute her body weight. "Initiating item activation." "Activation???" Suddenly, restraints extended from the horse's head, tightly securing Zhao Yuhan's wrists. This forced her to lie prone on the hobby horse. She could feel the hobby horse slowly rising. The wooden support structure suddenly became unstable as a spring was installed beneath the horse. That wasn't all. The sudden appearance of ropes completely stripped Zhao Yuhan of her freedom of movement. These were extremely elastic, pink, glowing ropes that, upon appearing, wove themselves into a tight binding around her body. Loops around her thighs, knees, calves, and ankles securely fastened her legs to the sides of the horse, forcing her legs into a tightly pressed, "M" shaped position. "Now, allow me to introduce the item. The randomly selected item is: The Spring-Loaded Hobby Horse. Its special effect is: it can rock on its own and is equipped with special accessories. The intensity of the horse's rocking is determined by the struggles of the user. The randomly selected rope this time is: Pink Temptation. This rope's special effect is: it possesses extremely high elasticity and releases a large amount of aphrodisiacs upon close contact with the skin. It will also continuously expand and contract over time." As the mechanical voice continued to emanate from the black card, Zhao Yuhan's heart sank like a stone. "I want—" "Proceeding with the installation of special accessories." Zhao Yuhan's words were cut off before she could even finish, as the first accessory to be installed was a gag that resembled a dildo, designed for deep throat insertion. "Mmph mmph mmph mmph mmph!!" She couldn't believe her bad luck, to encounter a random item with a gag again. Once she lost the ability to speak, it meant Zhao Yuhan lost control of the black card and was left entirely at the mercy of the restraint system. This gag was also different from previous ones. While past gags merely sealed Zhao Yuhan's mouth, this one filled her entire oral cavity. It not only pressed her tongue completely immobile but also gave her throat an intense feeling of a foreign object. Yet, no matter how much she gagged, she couldn't spit the ball out. This wasn't a custom restraint system at all!!!!! Zhao Yuhan screamed in her mind, but what she didn't expect was that there were more accessories to be installed. The appearance of an eye mask deprived Zhao Yuhan of her sight, stripping her of her ability to observe.

"Sister is too wicked..." Zhao Yuhan's small face flushed. Even though she had been played with by Chu Mushu many times, her heart would still race wildly every time Chu Mushu made a move. "After all, you used your points, so how can you not give me some compensation?" "Can't I just get it for free..." "No." Chu Mushu said word by word, and quickly stripped Zhao Yuhan's clothes off. No matter how you looked at it, Zhao Yuhan's body was so perfect. The only flaw might be the slight undulation of her breasts, which couldn't compare to Chu Mushu's voluptuous curves. "Let me think, how should I play with my little cutie this time~" "Can we try something a little more... relaxed? Like this... like this..." Zhao Yuhan hesitated, but Chu Mushu guessed her thoughts. "This way, you'll be played with for longer and earn more points?" Zhao Yuhan nodded slightly, confirming Chu Mushu's guess. But undeniably, Zhao Yuhan's face turned even redder at this moment. "Then, I'll do as my little cutie wishes~" This time, what Chu Mushu summoned with the restraint system was a pet restraint suit. "This is..." "I'm going to turn my little cutie into a little puppy." With the help of the restraint system, before Zhao Yuhan could even cooperate, this pink pet restraint suit was put on her. Instantly, Zhao Yuhan felt her hands and feet forced into a folded position. Between her upper arms and wrists, and her thighs and ankles, there were leather rings for fixation. The presence of these four pairs of leather rings was the culprit that forced Zhao Yuhan's limbs into a folded state. Chu Mushu quickly locked the leather rings, making Zhao Yuhan realize at a glance that she couldn't break free on her own. However, this pet restraint suit, made of special material, had excellent compatibility with her skin. It felt like latex to the touch, but it was very elastic, perfectly wrapping around Zhao Yuhan's body and giving her a feeling of being tightly bound all over. Restrained, Zhao Yuhan could only stand on her elbows and knees. She tried to adjust to moving in this position on the bed. "How is it? You don't feel uncomfortable, do you?" "Not at all. This feeling... it's actually quite nice..." "Then, it's time to add some toys~" "Eek!" Zhao Yuhan let out a scream, but immediately after, Chu Mushu unzipped the front of her suit, from her chest to her crotch.

In reality, Chu Mushu had nothing pressing to do. She merely wanted an excuse to leave and leave Zhao Yuhan here. *Clang!* As Chu Mushu slammed the door shut, Zhao Yuhan began her "placement play." Fortunately, her limbs were merely folded and restrained, not completely immobilized. Chu Mushu hadn't entirely sealed off her senses like her eyes and mouth, which presented Zhao Yuhan with a significant opportunity. "No, I have to get out of this room quickly. Sister Chu must be peeking from outside the door!" Burning with desire, Zhao Yuhan forcefully suppressed her inner urges and turned to find a way out of her predicament. The first step was to get off the bed. However, with her limbs folded, it wasn't easy for Zhao Yuhan to do this. In this state, she wasn't even as tall as the bed. But since Zhao Yuhan had made up her mind, she would fall to the floor even if she had to, so she unhesitatingly extended her "front foot"—her two arms—off the bed. As expected, due to her unstable center of gravity, Zhao Yuhan directly fell to the ground. "Ouch! That hurts!!!" This fall hit her head, leaving Zhao Yuhan dazed for a long time. She could only lie on her back, gasping for air. The next step was naturally to get to the door, but she had to roll over first. Lying on her back, Zhao Yuhan realized that rolling over was not an easy task. With her limbs restrained, Zhao Yuhan was like an overturned turtle. To flip herself over, she had to rock her body from side to side with significant amplitude to get her other limbs to touch the ground. This rolling process took Zhao Yuhan a considerable amount of time, as she had never experienced anything like it before. Fortunately, Zhao Yuhan eventually succeeded in flipping herself over, allowing her limbs to make contact with the ground.

The straitjacket felt remarkably like latex. Chu Mushu tugged at it forcefully, finding it to be highly elastic and resistant to tearing. The only opening on the straitjacket was at the neck. Once donned, it would bind the hands in front of the abdomen, while keeping the legs together. Without assistance, it was impossible to remove. Even so, Chu Mushu stripped off her own clothes with remarkable speed. Her body was revealed to be wrapped in bandages, and she then put on the straitjacket. "That's more like it." With another snap of his fingers, Zhong Xuan deactivated the toys on Parnu. Zhao Yuhan, finally freed, was still convulsing uncontrollably. The toys, vibrating at their highest intensity for just a few minutes, had nearly rendered her unconscious. In that moment, she truly felt as though she was breaking. "Sister Chu..." "And you, once you've put it on, I'll release Zhao Yuhan." Zhong Xuan's face once again contorted into a mocking, frivolous expression. It was clear that once the straitjacket was on, all ability to resist would be lost. At the very least, Chu Mushu, standing before him, would struggle to even squirm. When both of them lost their ability to move, whether Zhong Xuan would actually release Zhao Yuhan was anyone's guess. Even if Zhong Xuan reneged on his promise, they would be powerless. For the first time, Parnu found making a decision to be incredibly difficult. "If you don't hurry, I might just turn the toys back on." Zhong Xuan's finger traced a tantalizing curve across Zhao Yuhan's skin. Finally, Parnu made her choice. She stepped one foot into the room, simultaneously crouching down to pick up the straitjacket. "Now!!!" The silver bird hairpin emitted a dazzling light at that very moment. Absolute Territory, activate! Time within the domain was stretched infinitely, yet Parnu could act as if unaffected. Absolute Territory's duration was a mere ten seconds. Parnu rose swiftly and charged. She had only ten seconds, and within them, she had to shatter Zhong Xuan's mind! Parnu pulled out a bottle of red liquid and poured it all into Zhong Xuan's mouth. This step alone took Parnu five seconds.

Zhao Yuhan's eyes widened, but the restraints on her body prevented her from concentrating. Another orgasm washed over her, pulling her attention back to herself. "Master... has she been set up?" "Quick... Parnu... help me turn off the toys..." Although Zhao Yuhan didn't want Parnu to see her in this state, the situation had come to this. The most urgent thing was to quickly remove Zhao Yuhan's restraints and stop these damned toys. Parnu strode quickly to Zhao Yuhan and removed the toys on her one by one. Only then did Zhao Yuhan truly feel liberated, her entire body collapsing into Parnu's arms. However, to Zhao Yuhan's surprise, Parnu did not untie her ropes. "This is Master's black card." Parnu held Zhao Yuhan's black card in her hand. "Thank you... quickly help me untie the ropes..." "No." "Don't be silly... I'm very tired now..." "As long as Master is tied up, she will never leave Parnu." "Wait... Parnu, are you serious?" Unexpectedly, Parnu directly picked up Zhao Yuhan and carried her back to her bedroom. "Hey! Parnu, no!" Parnu's strength was astonishing, but bound in the horse-straddle position, Zhao Yuhan had no ability to resist and could only let Parnu carry her to the bed. "I'll sleep with you! So hurry and untie me, okay?" "No, Master is a liar." Unexpectedly, Parnu showed no intention of untying Zhao Yuhan. She simply lay down on the bed and held Zhao Yuhan tightly. "Um... are you planning to sleep holding me like this... it's bad for blood circulation... it's dangerous..." "I won't listen, I won't listen, I won't listen." "Parnu! I'm begging you, okay?" "Parnu doesn't want to hear anything. If Master speaks again, I'll stuff Master's mouth!" "No! It's really dangerous to be tied up for too long... Mmph!" Unexpectedly, Parnu even activated her black card and forcibly gagged Zhao Yuhan with a ball gag. Now, Zhao Yuhan truly couldn't speak. Fortunately, Parnu just held Zhao Yuhan tightly. At least with the toys removed, Zhao Yuhan wouldn't have any trouble for the time being. It was clear she was sulking. She needed to find a way to appease Parnu... However, facing this situation, Zhao Yuhan was truly helpless. She couldn't move, couldn't speak, and could only let Parnu hold her, unable to take any practical action. Soon, Zhao Yuhan felt the warmth of Parnu's body.

"Domain Expansion, Custom Restraint Mode, Activate." A crimson domain immediately enveloped the entire house. "Eh??? So fast? I'm not ready yet!!!" "Since you want to save someone, how can we not hurry? Let's make it clear, tonight's training is on a completely different level than before." "Save... Save me!!!" Zhao Yuhan felt fear once again. The restraints of the past few days had already made her miserable; she couldn't even imagine what she was about to face. Chapter 11 This time, the restraint was indeed different from usual. Zhao Yuhan's forearms and upper arms, and her lower legs and thighs were folded together and secured by leather cuffs. She lay on her back on the bed. Although her limbs still had some room to move, Zhao Yuhan couldn't break free from these leather restraints on her own. "Alright, that's all for the restraint part today. How does my little cutie feel?" "Better than... I expected." Indeed, although the restraints made of leather were tight, they weren't unbearable and were within Zhao Yuhan's tolerance. "Then, let's start adding accessories." Chu Mushu held two strange items in her hands. Zhao Yuhan could understand what she was holding in her left hand – a pink and white cat ear headband. However, she had no idea what the long, fluffy object in Chu Mushu's right hand was. "Tonight, you're going to be my cat~" "Cat??? You don't mean... that's a cat tail???" "Correct. I need to attach it to my little cutie, and it requires a little preparation." "Wait, where are you planning to attach that thing? You don't mean..." "Of course, it's going in the back. Little cutie, lie down obediently, and leave everything to your sister~" "No!!! Absolutely not!!!!" Unfortunately, no matter how much Zhao Yuhan cried out, she couldn't make Chu Mushu stop. Chu Mushu first put the headband on Zhao Yuhan, then picked up an oversized syringe, about as thick as Zhao Yuhan's arm, filled with some transparent liquid. "Speaking of which, little cutie hasn't explored her rear end yet, right? The first exploration gets bonus points." "I don't want those points at all!!!!" Zhao Yuhan wailed as she watched Chu Mushu aim the needle at her backside and insert it. The needle of the syringe Chu Mushu used was about as thick as an adult's little finger. With the help of lubricant, it was easily inserted into Zhao Yuhan's rear. "It might feel a little cold, but my little cutie must endure. Absolutely don't spray it on the bed." "No!!! Not there, absolutely not!!!"
