Choking Escape Challenge - Trilogy Complete

Then, she picked up her phone. The phone screen lit up, and the interface of an app clearly appeared in front of the camera. [Connecting to devices...] [Device 1: 'Peach' connected successfully!] [Device 2: 'Air Depriver' connected successfully!] These were the two wickedly named devices that Jiang Zhiyu had changed herself. Her fingers flew across the screen, setting the commands. [Device 1: 'Peach'] [Mode: Random Vibration] [Trigger Interval: 1-60 seconds (random)] [Vibration Frequency: Low/Medium/High/Burst (random)] [Vibration Duration: 5/10/20/30/60 seconds (random)] [Device 2: 'Air Depriver'] [Mode: Delayed Random Suction] [Startup Delay: 10:00 minutes] [Suction Interval: 5-60 seconds (random)] [Suction Duration: 1-5 seconds (random)] Jiang Zhiyu's gaze fell upon the large, transparent vacuum bag on the bed. She had tested this bag long ago. Even if it was evacuated to an absolute vacuum, as long as her hands were still functional, she could tear open the seal from the inside with all her might. That was a final escape route she had reserved for herself. An insurance policy to ensure the game wouldn't turn into a funeral. With this confirmed, she had no further reservations. Jiang Zhiyu knelt by the bed, her knees entering first. The cold touch of the plastic spread along her white stockings to her skin. "Swish—" She wriggled her entire body into the bag, like a mermaid sliding into a transparent cage. She didn't lie flat but, in a position that severely tested her flexibility, knelt and then reclined backward. Her entire body weight pressed down on her bent calves, which were tucked to the sides of her waist, forming a breathtaking arc. This posture stretched her body's curves to their limit, every inch of her skin exuding a fragile yet alluring beauty. She reached out and picked up a roll of gray heavy-duty tape that had been prepared beside her. "Rrrrip—" The piercing sound shattered the silence of the room. She tore off a long strip of tape and, without hesitation, firmly sealed her lips. The tape's adhesive was incredibly strong, pressing tightly against her lips and robbing her of the ability to cry out. From this moment on, she could only breathe through her nose. Having done this, she propped herself up again, her abdominal muscles trembling slightly with the effort. The tape was then wrapped around her curled legs, layer upon layer from thigh to calf, tightly binding her legs together and preventing her from straightening them. Simultaneously, her legs were firmly secured together, rendering them immobile. This tenacious restraint completely stripped her of her lower body's freedom. She fell back, exhausted, her chest heaving, her breathing becoming shallow. Next, she picked up a black latex hood. The hood emitted a distinct rubber scent. She skillfully stretched it open and pulled it over her head. The game, only one step left. Jiang Zhiyu's gaze fell on the peculiar black and red contraption in the vacuum bag. It looked like a pair of heavy boxing gloves, four fingers together, thumb separate, the surface made of smooth leather. But the wrists of the gloves were connected by cold metal clasps. This was a specially made restraint – boxing handcuffs. To unlock it required two steps. Step one: unlock the gloves. The handcuffs had a precise dial that needed to be turned clockwise until resistance suddenly lessened, completing the first layer of unlocking. One had to stop immediately; looking away meant failure and starting the whole turn over. Then, counter-clockwise for the second layer. Then clockwise for the third. Finally, counter-clockwise for the fourth. All four stages had to be passed to free the hands from the gloves. But that wasn't all. Step two: the hands were still locked by the metal cuffs at the wrists. The induction zone of the handcuffs had to be pressed against the magnetic card hidden at the sole of her white stockings. Upon hearing a "ding," the lock cylinder would fully open, and freedom would be regained. Any mistake at any step meant the challenge failed. Jiang Zhiyu twisted her bound body, laboriously bringing her hands behind her back. She picked up the boxing gloves, first shoving her left hand in, the leather lining snugly enclosing her fingers. Then her right hand. "Click!" A crisp metallic bite echoed. The clasps at the wrists automatically closed, locking her hands securely behind her back. Completed. The final restraint. She was like a sacrificial offering, with no possibility of escape. Just as she finished all preparations, lying in the vacuum bag, ready to enjoy the stimulating vibrations within her body— "Buzzzzz..." The continuous, low vibration abruptly stopped. The world instantly fell silent. Only her own labored, rapid breaths and the latex-squeaking sounds of the breathing hood remained. "What the hell..." Jiang Zhiyu's body froze, a wave of disappointment washing over her. She had just gotten into it, the main event hadn't even begun, and it stopped? Damn these random commands! At this moment, she was completely bound, imprisoned in this transparent bag. She couldn't even tell the time. How long until the vacuum pump started? Eight minutes? Or five? She didn't know. She could only wait. Wait for the unknown stimulation, set by her own hand, to descend. Don't panic! She forced herself to calm down, slowing her movements, trying to sense even the slightest shift in pressure beneath the thick leather. But the physiological panic of oxygen deprivation was beyond her willpower. Her hands began to tremble uncontrollably. Her movements, too, sped up of their own accord! Faster! Faster! *Click.* The resistance of the knob vanished abruptly! Found it! The first layer unlocked! However, just as she was about to stop immediately and turn counter-clockwise— *Vvvvvvvvv—!* Deep within her body, the long-dormant "peach" activated without warning, in its most violent and ferocious state! It was the burst mode! "Mmm—nnngh!!" An unprecedented wave of intense stimulation surged through her entire body! Jiang Zhiyu's body arched violently, like a drawn bow! Her legs, bound by tape, thrashed together, the muscles beneath her white stockings forming a seductive yet desperate curve. A muffled, alluring groan escaped her tape-sealed mouth. Her hands, which required precise positioning, were completely out of control at this moment! *Creak!* The glove, along with the knob, spun wildly! Failure! Jiang Zhiyu's pupils dilated, her body writhing violently from the extreme pleasure and extreme fear. She wanted to correct it immediately, to feel the knob's current angle with her gloved hand, to memorize its position. But the thick padding was like a wall, blocking all tactile sensation. She fumbled for a long time, feeling nothing but the padding inside the glove! She had to start over! She cursed inwardly, no longer caring about being careful. She knew the approximate location was about three-quarters of a turn away! Her hands no longer probed but spun the knob rapidly! *Vvvv—!* The vacuum pump's hum started again, this time as if to expel the last wisp of air from the bag. *Hiss—* Amidst the piercing sound of contraction, the vacuum bag transformed into a layer of cold skin, greedily devouring every inch of space. It clung tightly, tightly to Jiang Zhiyu's body, ruthlessly outlining her every exquisite curve. Under the extreme contraction of the vacuum bag, they became incredibly clear, incredibly taut! She quickly stopped her movements, using her gloved hands to brace open a gap behind her. She had to preserve this last sliver of space; it was her only hope of unlocking the handcuffs and breaking free! The vacuum pump stopped. But panic had completely consumed her reason. Her hands fumbled, twisting the knob frantically, her legs squirming anxiously within the vacuum bag. The burning sensation in her lungs caused her diaphragm to twitch uncontrollably. "I can hold it... I won't die..." Jiang Zhiyu repeated this phrase frantically in her mind, like a form of self-hypnosis. She tried to suppress her body's instincts with her mind, focusing all her attention on her hands behind her back. The thick boxing gloves turned the knob sluggishly. A faint tactile change registered at her fingertips. But her mind was constantly self-hypnotizing, ignoring this lifeline signal. *Click.* The knob was turned too far, re-entering an ineffective zone. *Vvvvvvvvv—!* Inside her body, the "peach" seemed to mock her failure and activated again! High-frequency burst! "Nngh!" Jiang Zhiyu's body arched violently. Her taped legs curled upwards uncontrollably, then slammed heavily onto the bed. *Bang!* Jiang Zhiyu's pupils contracted sharply. She began to twist the hands locked behind her back frantically, using the leather surface of her boxing gloves to desperately tear at the vacuum-sealed bag encasing her body! "Riiip! Riiip!" The smooth leather scraped uselessly against the equally smooth plastic, the sound like a mockery of her helplessness. Just like before, she couldn't tear it open! The extreme agony of her lungs being empty, though briefly suppressed by her brain, had given her a sliver of adaptation. But this did not mean the pain had vanished. That heart-wrenching, burning pain still raged within her body, merely preventing her from passing out again immediately. Handcuffs! She finally remembered! She had to unlock the handcuffs! Abandoning the futile attempt to tear the vacuum bag, she immediately tried to turn the damned knob! However, as she attempted to shift her hands, using her gloves to search for the knob— The vacuum bag moved in sync with her boxing gloves and hands. She exerted force again! Still moving in sync! During those brief ten-odd seconds when she lost consciousness, that damned "air depriver" had activated again! Now, her gloved hands were pressed tightly, seamlessly, against her back by the contracted vacuum bag! The plastic film, like a layer of skin, completely enveloped and secured her gloves and wrists! "No!" Only this one word echoed in Jiang Zhiyu's mind. Her hands were pressed so tightly against her back by the vacuum bag, she couldn't move them! She used all her strength, pushing backward with a sudden surge! The muscles in her arms instantly tensed, veins bulging! "Tear… it… open!" She roared internally. The plastic film clinging to her back finally yielded, a minuscule gap forced open by her sheer strength! A vacuum zone, devoid of any molecular elements, formed! However, before she could make any further move, that omnipresent suction force slammed into her. She felt her arms go slack, the gap she had just created vanishing instantly. "Thump!" Her gloved hands were violently sucked back by the negative pressure, slamming heavily against her back! This impact made her understand completely. Trying to turn the knob this way was utterly impossible! The moment her strength wavered even slightly, her hands would be sucked back, rendering all her efforts futile! Jiang Zhiyu's eyes turned red, a surge of brute force coursing through her. She pushed her hands apart behind her back again. This time, she ignored the damned knob and used the edges of her gloves to desperately tear at the vacuum bag! "Riiip— Riiip—" The leather scraped furiously against the thick plastic, emitting a grating sound. But the vacuum bag's resilience was beyond imagination; it showed no signs of damage! "Ugh… Hh…" The burning pain in her lungs, her diaphragm spasming uncontrollably, each spasm felt like it was tearing her lung tissue. Her body arched violently on the bed from the extreme agony! It was this movement! The instant her body arched, the negative pressure zone between her back and the vacuum bag was instantly enlarged! A flash of inspiration struck Jiang Zhiyu's mind! As if grasping at the last straw, she desperately maintained the arched posture of her body, while her legs, bound by tape, curled upwards at an extremely contorted angle. She could feel her toes, clad in white stockings, being slowly sucked into the vacuum zone behind her by the negative pressure! Closer… Just a little closer! The extreme agony of suffocation brought tears uncontrollably to her eyes, blurring her vision. Her body writhed violently on the bed, each movement expanding the negative pressure zone by another fraction. But when she looked at the gallium metal again, she was surprised to find that the already melted liquid gallium had begun to solidify, turning back into a block of silver metal. As if possessed, Jiang Yinian placed it back on the melting point tester, and the number that appeared on the instrument's screen made her pupils contract sharply. [38.0°C] The melting point had changed from thirty degrees to thirty-eight degrees. Back home, Jiang Yinian placed herself inside the familiar vacuum bag once more. This time, a simple pair of handcuffs, which she had personally forged from that contaminated alloy, lay before her. A wild thought took shape in her mind. Normal human body temperature is thirty-seven degrees. And the melting point of this metal is thirty-eight degrees. If... If she were to bind herself with it, and in a state of suffocation, would her body's instinctive struggle cause her temperature to rise, thus melting it? Using her own body heat to melt her restraints, to achieve a truly extreme escape! This seemed... more interesting than her sister's complex handcuffs that required a magnetic card! Her heart began to pound uncontrollably, and Jiang Yinian licked her dry lips. She extended her hands into the pair of cold metal handcuffs. "Click." The handcuffs locked securely. She lay down in the vacuum bag and skillfully used her toes to hook the vacuum pump's switch through the bag and press it. "Whirr—" The air was evacuated. The sensation of suffocation washed over her like a tide, the air in her chest being squeezed out bit by bit. Two minutes later, the agony of suffocation surpassed the pleasure. She exhaled the breath she had been holding and began to struggle instinctively, twisting her body. She could feel her body rapidly heating up, her skin becoming scorching hot. She continuously curled and stretched. Just as she could no longer hold her breath, thinking her attempt had failed and wanting to open the vacuum bag's seal directly... "Drip... drip..." The hard metal handcuffs slowly turned into silver liquid, flowing down her wrists and dripping onto the plastic bag. It... Was softening! She felt it! The softened gallium alloy was no longer firm, and Jiang Yinian easily separated her hands. Her hands were free again! She tore open the vacuum bag violently, gulping in air. She had succeeded! She had created a perfect game, one that belonged only to her, where life and death were controlled by her own body temperature! Jiang Yinian looked at the pools of silver metal that quickly cooled and solidified again. "Sister..." She whispered softly, a flicker of sadness in her eyes. "If I had used this, would I have... survived?" Once again. Jiang Yinian stood naked on the cold bathroom tiles, feeling the liquid gallium metal slowly flow down her wrists. The silver-white metallic liquid clung tightly to her skin, perfectly replicating every contour of her wrists. She closed her eyes and waited quietly. The metal's temperature rapidly dissipated, the sensation of liquid flow disappearing, replaced by a gradually tightening solidification. The metal completely solidified, locking her hands firmly behind her back. This was not enough. She stepped into the basin and poured a pair of metal shackles onto her feet as well. Her body was completely restrained, unable to move. But this was exactly what she wanted. In the ocean of videos her sister had left behind, she had seen countless unimaginable ways of restraint. She wanted to understand, to feel, to become her sister. So, she began to imitate, from the simplest ropes, to the gallium metal her sister had never used. Each successful escape fueled her desire for the next challenge. This sense of control, teetering on the edge of losing it, captivated her. However, mere restraint no longer seemed to satisfy her. The film immediately caved in with her inhalation, clinging tightly to her breathing holes, completely sealing out air. No air. Not a single bit. "Mmph! Mmph mmph!!" Lin You shook her head frantically, trying to dislodge the film. But under Amy's pulling hands, the cling film remained unmoving. Amy was executing the command. The cling film rotated downwards around Lin You's head. Lin You's body began to writhe violently, her torso, tightened by the turtle shell binding, struggling to twist. Her hands, bound into a ball by tape behind her back, slammed against her own spine. Her legs, though tied down, still attempted to find a point of balance by bending her knees, trying to lunge at Amy, even if it meant falling over herself. Just to make it stop! Just to make Amy realize her master was in mortal danger! "Mmmph—!!!" Lin You let out a continuous, urgent whimper. In her mind, she screamed: Amy! Core protection function! Trigger it quickly! Your master is dying! Check my heart rate! Check my blood oxygen saturation! All domestic androids were programmed at the factory with unmodifiable core logic—a variation of the "Three Laws of Robotics." The first of these was: A robot must not harm a human being, or, through inaction, allow a human being to come to harm. When the master's vital signs dropped to a dangerous threshold, regardless of the current mode or the command being executed, the android had to forcibly interrupt and prioritize rescue. This was Lin You's last lifeline. However, Amy didn't stop. The cling film in her hands continued to spin rapidly, extending from Lin You's head downwards, wrapping around her neck, around her shoulders. Amy's command code was running. [Current command set: Full cling film wrap.] [Command details: Completely wrap the target from head to toe, forming a chrysalis shape, with breathing holes poked at the mouth and nose.] Amy's logic core was performing a meticulous calculation: The command required "wrap first, then poke holes." This meant that the absence of breathing holes before the wrapping was complete was consistent with the procedural logic. In other words, the command itself included the process of "temporary suffocation." Since the command included this process, the target's suffocation reaction before the end of the procedure was judged as an "expected normal phenomenon," rather than "accidental harm." Moreover... Lin You thrashed her body in agony. The continuous whimpering had completely depleted the air in her lungs, leaving her in a state of empty lungs. The burning sensation in her lungs made her feel like she was about to explode. Why? Why wasn't the protection mechanism triggering yet? Suddenly, she remembered. It was half a year ago, on a hidden underground hacker forum. Lin You had contacted a hacker specializing in cracking android systems. "I want a more thrilling experience." At the time, Lin You, seated elegantly on the sofa, had said to the hacker on the holographic projection: "The current Amy is too timid. If I push it a little, like holding my breath for longer, or my heart rate getting higher, it automatically stops the game. It's such a buzzkill." "I can help you load an 'Extreme Erotic Mod'." The hacker's voice, altered by a voice changer, sounded like a villainous boss. "This mod will add an 'exemption' to Amy's core logic." "What exemption?" "When the erotic mode is active, it will default all of the master's physiological pain responses—including suffocation, spasms, and even shock and unconsciousness—as part of the 'enjoyment'." A single vertical line connected the upper and lower restraints into a unified whole. Amy picked up the longest, thickest main rope again. And the black metal device – the rope tightener. Through the blurry layers of tape, Lin You saw the thing. It was the prop she had used last time for the Four-Horse Yoke. Once the switch was pressed, the gears would engage, the rope would tighten inch by inch, and it would absolutely not retract. Amy threaded one end of the long rope through the exposed gag strap above Lin You's head. This was the point of force connecting her chin to the back of her skull. Once pulled, her head would be forced back. The other end of the rope went through the loop at Lin You's wrist position behind her back. Finally, it went through the loop at her ankles. Three points in a line. Head, hands, feet. These three points were strung together by this single rope. Amy inserted both ends of the rope into the left and right rope-in ports of the rope tightener. Then, she hung the tightener in the middle section of the rope, behind Lin You's back. "Four-Horse Yoke configuration reconstruction complete." The buzzing of the vibrator raged within her body. Lin You's body was wrapped into a stiff, red rod. Apart from a slight wiggle, she couldn't even bend a finger. Amy held the black tightener, her finger hovering above the switch. Lin You's heart was about to burst through her chest. Don't press it. Absolutely do not press it. As long as the button wasn't pressed, the Four-Horse Yoke that would fold her into an "O" shape wouldn't activate, and she would still have a sliver of hope. Amy's finger moved. But she didn't press the activation button. "Command verification..." Amy's voice was unnervingly steady. "Detected current command: fusion of 'Deep Water Escape' and 'Extreme Four-Horse Yoke'." "According to program optimization, body folding (Four-Horse Yoke tightening) should occur synchronously during water entry to increase escape difficulty and stimulation." "Therefore, the activation of the tightener is postponed to the final step." Before Lin You could even breathe a sigh of relief, she felt her body lighten. Amy bent down, her arms easily slipping under Lin You's bound knees and behind her neck, lifting her into a horizontal embrace. "Mmph! Mmph mmph!" Lin You thrashed her head desperately. Through the layers of transparent tape, the scene before her was distorted and blurry. Amy's exquisite yet expressionless face was inches away. Amy held her, walking step by step towards the enormous diving pool. A huge, transparent, custom-made vacuum bag was placed there. This was custom-ordered by Lin You, made of thickened composite plastic material, extremely tough, and not easily punctured even with scissors. Her legs were tightly bound in a turtle shell restraint. Outside the hemp ropes, they were wrapped in plastic wrap. Outside the plastic wrap, strong tape. Outside the tape, another layer of hemp rope. This layered binding made her legs feel fused together. Let alone spread apart, she couldn't even create a sliver of space between them. She could only desperately feel the pressure of her inner thighs against each other, the numbness and stinging from the restricted blood flow. Lin You didn't know. The vacuum bag she was in had already been pulled five meters underwater. The resistance limit of the breathing valve was fast approaching. But Lin You couldn't concern herself with that now. Because her body was enduring a more brutal torment. During this time, the rope tightener slowly pulled the ropes behind Lin You to their absolute tightest. This was the true limit. Lin You's head and toes were being pulled to their extreme. Her body was completely folded into a perfect "O". Even... Her toes had completely touched the back of her head. This was the limit of Lin You's flexibility. And the limit of her pain. The horse-fetter restraint was finally complete. Lin You's neck was pulled excruciatingly, her trachea stretched. She wanted to lower her head to relieve the pressure, even by a centimeter. She couldn't. The ropes held her chin fast. A searing pain, as if her waist would snap, radiated from her midsection. She wanted to pull her legs back, to straighten her knees. She couldn't. The ropes held her ankles fast. This position made it impossible for her to even lie prone. Because her body was curved, the bottom was a rounded arc. Lin You could only lie at the bottom of the vacuum bag, swaying back and forth with the gentle undulation of the water. Like a rocking horse. Swaying back and forth. The vacuum bag swayed in the dim water. Lin You lay at the bottom of the bag, maintaining that humiliating kneeling posture. Her spine was pulled backward into a taut bow, her head nearly touching her heels. This unnatural, contorted position kept her lower back muscles on the verge of spasms. She stopped moving. Not because she didn't want to, but because she had completely run out of strength. The frantic struggle just moments before had exhausted the last reserves of power in her muscles. Now, even moving a finger—her fingers were already balled up and taped—was a distant hope. Silence surrounded her.
