My Sister-in-law's Summer Vacation

"Damn capitalists, I'll fire you sooner or later!" I cursed hatefully, my hands never stopping, my fingers flying across the keyboard. My name is Lin Ye, a miserable corporate slave. I work diligently, earning a meager salary each month. But I've never hated my boss this much before. It's Saturday, and I should be resting at home, but a call from my boss dragged me back to the office to work overtime, staring at the computer and churning out boring quotation sheets. Perhaps you're thinking, "What's the big deal? Who isn't a wage slave? This is commonplace." But what if I told you that at this very moment, my wife, Ruolan, is tightly bound and restrained by me, struggling and moaning in the iron cage in the corner of the living room? Does that still seem commonplace? Here's how it happened. This morning, I thought I'd finally get a day of rest. Ruolan thought so too. So, early in the morning, Ruolan changed into a sexy, alluring qipao and purred at me, "My dear husband, you haven't disciplined and trained me for a long time. We both have the day off today, aren't you going to do something?" Hearing this, I immediately perked up and leaped out of bed. We've been married for five years, and we share a secret: we both enjoy thrilling, unconventional S&M games. I'm the S, and Ruolan is the M. It's just that we're usually so busy with work that we rarely get a chance to indulge. "Hee hee..." Ruolan looked at me charmingly. "Husband, no, respected Master, I want to be a slutty little bitch today and be played with by Master all day, okay? Master!" "Slap!" I smacked Ruolan's tender, full buttocks, eliciting a seductive moan from deep in her throat. I said excitedly, "Then what are you waiting for, you slutty little bitch? Hurry up and go kneel before your iron cage. When this Master is done with his morning routine, I'll come and deal with you properly!" "No, Master, please, let me serve Master with his morning routine!" Ruolan said, kneeling obediently by the bed. She purred charmingly, "Please, Master, bestow upon this slutty little bitch your big hard cock!" "Hiss..." I looked at Ruolan's hazy eyes, her delicate face, her flushed cheeks, and couldn't help but gasp. The thick, hard cock between my legs immediately swelled and stood at attention, creating a massive tent in my silk pajamas. "Fine, then this Master will make an exception and bestow it upon you this once!" With that, I got up and walked into the bathroom, standing before the sink to wash up. "Thank you for the bestowal, Master!" Ruolan crawled on the floor, following closely behind me. She came between my legs, directly taking my massive cock into her mouth through the silk pajamas, and began to lick and suck it. "Ah..." My whole body trembled. I almost shoved the toothbrush into my nostril. Even through the thin silk pajamas, the extreme tingling pleasure surged through me, making my legs tremble slightly. Ruolan's face is stunningly beautiful, like a blooming flower. She was definitely the campus belle back in the day. If I hadn't accidentally stumbled upon her secret liking for S&M, and if we hadn't gotten together after that, I doubt she would have looked twice at me, even though I'm quite confident in my own looks. If you knew Ruolan, you'd only think of her as a cold, intellectual beauty. You'd never imagine the seductive, decadent heart hidden beneath her noble exterior. After five years with her, I can't say I know her completely, because she always surprises me with new discoveries, new insights, and new understandings. This fills me with the joy of having found a treasure. I think almost every man would be unable to refuse a wife who is a lady in public and a slut at home, right? Fortunately, Ruolan is exactly that. Just like now, while I'm washing up, she's kneeling respectfully at my feet, her small mouth wide open, engulfing my massive cock, meticulously licking and sucking it, sending waves of tingling pleasure through me. My thick cock trembles in her mouth. I looked down at Ruolan. She had her hands clasped behind her back, her forearms together, resting horizontally at her lower back, her elbows touching. She remained motionless. Indeed, once she enters her role, Ruolan doesn't use her hands or arms, even though there are no ropes binding her. I nodded in satisfaction. Holding my toothbrush in one hand, I pulled down my silk pajamas with the other. My massive cock sprang out of the pajamas, standing erect in mid-air, trembling and swaying slightly. Before my poor, massive cock could even catch its breath, Ruolan's small mouth opened again, swallowing it whole. Her delicate head bobbed between my legs. "Mmm..." My mouth was full of foam, and I could only let out a satisfied groan. I leaned slightly to the side, allowing Ruolan to serve me meticulously. With every stroke, she swallowed my massive cock deep into her throat, making my rounded glans collide with her tender flesh. The extreme tingling sensation swept through my entire body. I felt my blood boil with desire. In this decadent and stimulating state, I quickly finished washing up. The cock between my legs had already swelled to its limit, as if it were about to explode. I looked down at Ruolan again. The blush on her delicate face deepened, and her head bobbed fiercely, one stroke after another, without pause. Silky saliva dripped from the corners of her tender lips, making the area between her large breasts wet and filled with a unique, decadent aroma. I brought a leather collar, fastened it around Rulan's neck, and tightened it fiercely, clicking it shut behind her head. Then, I took hold of the long chain attached to the collar and led her towards the living room. The slight pressure around her throat made Rulan's breathing quicken, her face flushing even more, like an overripe red apple, so alluring and beautiful, inviting closeness, always giving me the urge to lean in and take a bite. Rulan crawled on the floor, following me, and slowly arrived in the living room, kneeling directly on the ground, waiting quietly. I unrolled a bundle of hemp rope, draped it around her neck, and began to wind and bind her relentlessly. Soon, a tight, sexy diamond-shaped *kote-gawa* bondage was formed on her delicate body. The crisscrossing ropes complemented her semi-transparent, sexy qipao, exuding a seductive, unconventional beauty that made my eyes redden, on the verge of erupting with intense lust. The tight, semi-transparent qipao was already incredibly sexy, clinging to her graceful form and showcasing her perfect S-curve to its fullest. The deeply imprinted ropes added a powerful, unconventional visual impact of stunning beauty, making my nostrils flare, almost to the point of a nosebleed. After completing the diamond-shaped *kote-gawa*, I brought out two small nipple clamps. Through the thin, semi-transparent qipao, I clamped them fiercely onto Rulan's delicate nipples. "Mmm… Ah… Master… It hurts… It hurts… So good…" Rulan's breasts weren't particularly large, but their shape was exquisite, like two tender pears. Encased by the semi-transparent qipao, they protruded from the gaps in the ropes, swaying gently against her chest. Beneath the delicate clamps, two small palace bells hung, emitting a series of pleasant, crisp chimes. They seemed to possess a unique rhythm, sounding like heavenly music to my ears, mingled with Rulan's seductive moans and words, setting my entire body ablaze. "Little bitch, you love it when this Master abuses and plays with you roughly, don't you?" I reached out and gently pinched Rulan's delicate cheek, looking down at her from above, a slight smile playing on my lips. "Mmm… Ah… Yes, Master, please be rougher, don't pity your little bitch!" Even though her face was contorted by my grip, Rulan didn't flinch at all. Her hands remained behind her back, unmoving, as she murmured. "Is that so?" A slight smile played on my lips as I looked at the alluringly beautiful Rulan, my sadistic desires thoroughly ignited. With a "slap," I struck Rulan's delicate cheek. "Little bitch Rulan, do you get more excited the more you're abused?" "Ah… Yes, Master, please be harder…" Rulan's delicate face was flushed crimson, her eyes hazy, a boundless primal desire and unconventional pleasure swirling within them. She let out a soft, seductive cry. "Heh… What a slutty bitch!" I raised my hand again. With a "slap," I struck the other side of her face, this time with a bit more force. "Ah… Master, just like that… Oh… Thank you, Master… Your little bitch loves being slapped and abused by Master… Ah…" I went back and forth, slapping each of her cheeks fiercely five times before stopping, leaving her kneeling on the ground, moaning softly, the surging desire in her eyes about to burst forth. At this moment, Rulan's delicate face was completely red, faint handprints subtly visible, making her look even more alluring and seductive. Her eyes seemed veiled by layers of mist, on the verge of condensing into teardrops and falling from the corners. Seeing Rulan in this state, I naturally understood that she was struggling and lingering on the verge of ecstatic delirium. I unrolled a new bundle of rope and commanded her softly, "Little bitch, extend one hand!" "Yes, Master!" Rulan replied obediently, extending her right hand from behind her back, her left hand remaining still in its previous position. I grabbed the rope and tightly bound her wrist twice. Then, I folded her arm upwards, her forearm pressed firmly against her upper arm, and bound it tightly. Soon, the ropes dug deeply into Rulan's delicate skin, restraining her arm so it couldn't move. Her small fist was pressed against her shoulder, with no room for any displacement. Next, I took the rope and did the same to her other arm. Now, her arms looked as if her forearms were gone, only extending to the elbows, exuding a peculiar sense of incomplete beauty. "Mmm…" I nodded with satisfaction. "That's more like it. A little bitch should act like a little bitch!" "Mmm… Ah…" The intense feeling of constriction clearly made Rulan extremely excited. Her kneeling body trembled slightly, and soft, seductive moans emanated from the depths of her throat. I brought out two black leather restraint cuffs and put them on each of Rulan's elbows, tightly enclosing her folded arms. I slowly adjusted the drawstrings on the sides and tightened them fiercely, tying them off. The leather restraint cuffs were custom-made to Rulan's body size, fitting snugly against her delicate arms, tightly encasing and restraining both her forearm and upper arm. The surface of the leather even showed the imprints of the ropes, creating an unconventional aesthetic. After tying the drawstrings, the two restraint cuffs now completely enclosed and secured her arms, including her small fists. I then pulled the restraint straps at the end of the leather cuffs, above her fists, tight and locked them, securing each with a delicate small lock. These two small locks secured both the restraint straps and the drawstrings of the leather restraint cuffs. Unless forcibly broken, no one could remove Rulan's arms from the tight enclosure without unlocking them. I was so excited I almost jumped out of bed. What did I tell you? My wife, as expected, knows exactly what I want. So understanding. Well, actually, I hadn't said anything, but that didn't matter. I flipped over and pinned Ruolan beneath me. "Mmm... Master, don't rush," Ruolan squirmed and struggled beneath me, purring seductively. "Ruoxi is already asleep. We have plenty of time. Please, Master, punish this little bitch severely..." I didn't hesitate. I reached for the bedside drawer and pulled out several bundles of rope and some small toys. Hmm... Ruolan and I usually only use the master bedroom, so these were all I could find in the spare room. I unfurled a bundle of rope and eagerly stripped Ruolan's long dress off. Twisting her hands behind her back, I began to wrap and bind her with the rope. "Mmm... Ah... Master, tie it tighter... Oh... So tight, so good... Master... harder..." As the rope tightened, Ruolan let out a series of sweet, seductive moans from deep in her throat. Her pretty face was flushed with an endless blush, like a ripe red apple under the lamplight. The rope danced through my fingers, one strand after another, winding around Ruolan's arms and digging into her tender skin. Soon, her hands and arms were bound together tightly behind her back, forming a perfect, snug bind. The figure-eight loops cinched Ruolan firmly, immobilizing her. Her arms were held behind her in a sexy, beautiful "Y" shape, her forearms pressed tightly together with no space between them. "Mmm... Ah... Master, you're so amazing. This little bitch loves being restrained like this. Oh... Please, Master, continue. Keep binding this little bitch until she can't move anymore..." Ruolan was clearly teetering on the edge of ecstasy, struggling against the intense feeling of restraint. Seductive moans echoed through the small room. An endless ripple surged within me, as if an invisible hand was stirring deep within my heart, making me restless. I unfurled a new bundle of rope and tightly bound Ruolan's tender, pale breasts and slender waist, securing her arms and body together with no gaps, no room to separate them. Ruolan's entire upper body had become one inseparable unit. The crisscrossing ropes were the most beautiful adornment on her delicate body, adding an incredibly alluring and seductive aura. My eyes grew hazy, and the hardness between my legs felt like it was about to explode. With new rope, I folded Ruolan's legs, pressing her calves tightly against her thighs, and began to bind them. Soon, her legs were bound in a standard M-spread position. The rope dug deep into Ruolan's tender skin, dividing her legs into segments of sexy, plump flesh that bulged out between the ropes. Under the lamplight, they gleamed with a jade-like luster, looking so alluring and seductive. "Mmm... Ah... Master, it's so tight, so stimulating. This little bitch loves you so much... Ah..." Ruolan writhed on the small bed, her throat emitting a series of high-pitched, muffled moans. Her eyes were hazy, as if veiled in mist, on the verge of forming tears. Looking at Ruolan squirming before me, I could no longer suppress the itch and tremor in my heart. I stripped off my sleepwear and straddled her pretty face, bringing my massive hardness to her lips. I lowered my upper body between her legs, assuming a perfect 69 position with her graceful body. My iron-hard cock plunged fiercely into Ruolan's mouth. "Mmmph..." Ruolan opened her small mouth wide to receive me, allowing my massive hardness to slide all the way in, deep into her soft throat, grinding against her tender flesh, filling her mouth completely. Ruolan's legs were tightly bound and spread open, her tender blossom just inches away, fully exposed before me. I lowered my head, took it into my mouth, and began to lick and suck fiercely. "Mmmph..." Ruolan's whole body trembled and writhed. A deep, resonant moan escaped her throat as her small mouth tightly enveloped my massive hardness. Her nimble, fragrant tongue licked and sucked at the base of my cock. A surging desire and a unique pleasure swept through Ruolan and me, building and fermenting rapidly, making our bodies burn with heat and unparalleled excitement. I sat up, picked up a powerful vibrator, and thrust it deep into Ruolan's tender, slick blossom. I flipped the switch, and a buzzing sound immediately emanated from her tender flesh. Ruolan's moans grew louder, but she couldn't utter a single word, her mouth completely blocked by my massive cock. Crystal-clear fluids flowed freely before my eyes, soaking into the bedsheet beneath Ruolan, leaving a large, lewd wet stain. I couldn't resist leaning closer and licking and sucking fiercely at her blossom. A decadent aroma wafted through my senses. The vibrator ravaging her depths sent tingles of numbness through my lips and tongue. Combined with the intense, tight pleasure from below, I sank deeper and deeper into primal desire, unable to extricate myself. Soon, we could no longer hold back. I leaned back slightly, withdrawing my massive cock from Ruolan's throat. I picked up the rope and tied it tightly around her knees, then looped it around the headboard and pulled hard, binding her legs to her chest, almost folding them against her upper body. I stood by the large bed, unsure how to begin. Ruolan gave me a look, urging me on, "What are you waiting for? You're the man, shouldn't you take the initiative at a time like this?" "I..." I gritted my teeth, deciding to go for it. I unfurled a bundle of hemp rope, extended my trembling hands, and slowly lifted the thin brocade quilt from Ruoxi. I pulled her up from the small bed and had her sit on the edge, her back to me. "Mmm... Brother-in-law... you... be gentle!" Ruoxi's voice was a mere whisper, her earlobes flushed crimson. I didn't reply. Instead, I twisted Ruoxi's hands behind her back and began to wind the hemp rope around them, binding her. Considering this was Ruoxi's first time experiencing bondage, I didn't tie it too tightly. I opted for the Japanese rear-naked tie instead of a rigid European straight-arm bind. As the rope touched her skin, Ruoxi shivered, a faint moan escaping from the depths of her throat. To my ears, it was like heavenly music, transforming into an invisible hand that fiercely caressed the softest parts of my soul, sending ripples of desire through me. My lower body, already hard and erect, strained against my pants, forming a substantial tent. Ruolan sat on the edge of the large bed, watching me meticulously wrap the rope around her younger sister, Ruoxi. Her gaze shifted, and when she saw the tent straining against my trousers, a flicker of an unreadable light crossed her eyes. She couldn't help but dart out her tongue, lightly licking her tender, red lips. "Hiss..." My eyes happened to catch this seductive and alluring sight, and I couldn't help but gasp. Ruolan seemed unaware of how incredibly enticing her subconscious gesture was, igniting an overwhelming primal urge within me. My erection grew even harder, seemingly on the verge of bursting through the confines of my pants. The rope began at Ruoxi's wrists, then wound up her upper arms, across her chest, binding her large breasts tightly on either side. It then looped back around to her behind, where I cinched it tight and tied a knot, securing her arms firmly against her body, leaving no room for movement. The standard, tight Japanese rear-naked tie caused Ruoxi's whole body to tremble. A soft moan escaped her lips as she murmured, "Brother-in-law, this... this feeling is so strange... so embarrassing... mmm..." "Hehe... My dear sister, how is it? Isn't it exciting and stress-relieving? Enjoy it!" Ruolan giggled. "Sis... this... Oh... it's so tight, I can't move..." Ruoxi's pretty face was flushed crimson. She tried to twist her upper body, but I had reinforced the rope at all the crucial points, leaving her no space to escape. After securing Ruoxi's upper body, I stepped back, watching her writhe and struggle against the rope's embrace. Her large breasts, constrained by the rope, appeared firm and round, pushing out from the gaps, swaying with her movements, exuding an unconventional beauty and allure that made my breathing quicken and my nostrils flare, as if I might get a nosebleed at any moment. With difficulty, I tore my gaze away from Ruoxi's ample cleavage. I helped her lie down on the small bed, then unfurled a new length of rope. I brought her slender legs together, binding her ankles tightly before threading the rope between her legs and cinching it, creating a figure-eight loop that held her feet firmly together, preventing them from separating. "Mmm... Brother-in-law... gently... it's so tight... oh..." Ruoxi lay on the small bed, her body writhing slightly, soft, alluring moans escaping her throat as she murmured. A faint smile played on my lips as I said softly, "Ruoxi, this needs to be tight. If it's too loose, and you struggle, the rough rope will chafe your skin and injure you!" "Ah... is... is that so?" Ruoxi's pretty face was covered in a blush. "Then... you can continue! Mmm..." I pulled the rope upwards, winding it around her long legs. At intervals, I tied tight figure-eight knots, continuing all the way to her thighs, binding her legs together without any space between them. Of course, by the time the rope reached above her knees, I incorporated the hem of her nightgown into the binding. In front of Ruolan, I still didn't dare to openly lift Ruoxi's skirt. At this point, Ruoxi was covered from head to toe in a crisscross of hemp rope. The ropes dug into her tender flesh, making her look incredibly sexy and alluring. The two sisters, like orchids, bamboo, plum blossoms, and chrysanthemums, each with their own unique charm, were now both bound and restrained by a dense network of rope. I felt a heat surge through my entire body, a primal desire and a unique pleasure welling up within me. My blood felt like it was boiling, as if it would ignite into a raging inferno, consuming my body and soul. Ruolan watched me, my expression bordering on wolf-like, and giggled, "Alright, husband, you go back to the master bedroom first. I'll chat with Ruoxi for a bit, and then I'll be back." "Ugh..." My face darkened. She was discarding me too quickly, like a used tool, without a moment's hesitation. But I knew I shouldn't stay any longer, or something might happen. I sheepishly returned to the master bedroom. In the master bedroom, I became even more restless. The image of the two sisters, Ruolan and Ruoxi, bound tightly by the rope, kept replaying in my mind, refusing to fade. My heart was aflame, my desire soaring. In the depths of my heart, I was already envisioning the day when I could unrestrictedly bind and train them both, a scene I imagined would be incredibly stimulating. Ruolan's gaze settled me slightly. Ruoxi, however, seemed impatient. She turned around, placing her hands behind her back, and urged, "Brother-in-law, hurry!" Gazing at Ruoxi's graceful, slender back, I steeled myself. I unfurled a bundle of hemp rope, grabbed Ruoxi's wrists, and tightly wrapped two loops. Then, I threaded the rope through the middle, tightening and securing it to form a snug figure-eight knot, binding Ruoxi's hands together without leaving any space between them. "Mmm..." As the hemp rope touched her skin, Ruoxi's body trembled slightly. A faint, soft moan escaped her throat, her earlobes flushing crimson. She murmured, "Ah... Brother-in-law, so tight... Oh... it needs to be this tight. Today... today I must surpass my sister... Mmm..." Ruoxi's voice was soft and sweet, intoxicating me. Ripples of emotion spread through my body, like enjoying a delicious ice cream on a scorching hot day. At this point, I could no longer hold back. My hands trembled slightly as I pulled the rope upwards, continuing to bind Ruoxi's clasped forearms. The rope, as if alive, danced at my fingertips, climbing up Ruoxi's delicate arms. At intervals, I tightly secured figure-eight knots. Soon, I reached the base of her arms, binding her hands and arms together into a sensually beautiful "Y" shape. This standard reverse straight-arm bind forced Ruoxi to arch her chest. Below her elbows, her arms were pressed tightly together, leaving no gap and preventing any separation. Even above her elbows, her arms were drawn inwards, the space between them too narrow for even her small fists. The intense feeling of restraint caused Ruoxi to emit a series of alluring moans from her throat. Her eyes glazed over slightly, and she murmured, "Brother-in-law, oh... so tight, even tighter than yesterday. This feeling is so strange... I feel like my body is on fire... Mmm..." Looking at Ruoxi's exquisite, alluring figure, my heart raced. With Ruolan present, I forcefully suppressed my surging desires. I unfurled a new bundle of rope and tightly bound Ruoxi's large breasts and slender waist, securing her arms and body together without any gaps, merging her entire upper torso into one. Ruoxi's entire upper body was tightly bound by the ropes into a standard European-style straight-arm bind. The ropes seemed to become her most beautiful adornment, digging into her tender flesh, binding and restraining her fiercely, leaving her no room to struggle or squirm. Her large breasts, constricted by the ropes above and below, appeared even firmer and rounder, protruding through the gaps in the ropes like two small peaks, towering on Ruoxi's chest. It seemed as if they would burst through the confines of her white shirt at any moment, leaping out. They swayed slightly, causing my nostrils to heat up, almost to the point of a nosebleed. Ruolan leaned against the doorframe, having watched the entire process of me binding Ruoxi. Her bright eyes were now hazy, filled with an unspoken desire and a peculiar pleasure. Clearly, she was on the verge of losing herself in a state of ecstatic arousal. "Mmm... Ah... Brother-in-law!" Ruoxi's body trembled slightly, her voice a soft murmur. Her delicate face was flushed with an endless blush, her eyes also hazy, as if she were desperately enduring the onslaught of her primal desires. I unfurled new ropes, tightly binding Ruoxi's slender waist twice, then proceeding downwards. I bound her long, shapely legs together with her pleated skirt. After wrapping the ropes around the skirt, I made sure to thread them between her thighs and tighten them, forcing her legs together without any space between them, held captive by the ropes, unable to separate even slightly. The smooth, silky feel of her thin stockings combined with the excellent elasticity of Ruoxi's legs created a tantalizing sensation that rippled at my fingertips, like a faint electric current coursing through my body, setting me ablaze. Blood rushed downwards, and my erection strained against my pants, forming a large tent, threatening to burst through the fabric at any moment. Ruolan, standing beside me, naturally noticed my reaction. Suddenly, she let out a soft chuckle and said playfully, "Someone's saying no with their mouth, but their body is telling a different story. Such a hypocrite!" Though Ruolan was panting, clearly not yet recovered from the aftershocks of her orgasm, she still obediently struggled and crawled behind me. Soon, we arrived at the living room. Ruolan obediently crawled to the dog cage, knelt properly, and said charmingly, "Please, Master, bind this little bitch and put her in the cage!" My heart surged. Looking at Ruolan, as beautiful and delicate as a flower, docile and obedient, I felt the lust within my body slowly boil again. The thick hardness between my legs trembled, stirring once more. "Heh... you slutty little bitch, if it weren't for the fact that this Master has to go to work tomorrow, I'd definitely fuck you one more time to show you how capable I am!" I grabbed a bundle of hemp rope, unfurled it, turned behind Ruolan, twisted her hands and arms behind her back, and bound her tightly. The hemp rope dug fiercely into Ruolan's tender skin, winding and coiling around her arms. Soon, her hands and arms were bound tightly together, unable to separate even slightly. After binding Ruolan's arms, I took a black leather restraint glove, spread it open, and slipped it onto her bound hands, pulling it all the way to her armpits. The restraint glove completely encased her bound hands and arms. As I gradually tightened the drawstring behind, Ruolan's arms sank into the tight embrace, leaving no room for movement whatsoever. I pulled the drawstring tight and tied a knot, then tightened and locked the restraint straps at the wrists, elbows, and upper arms. I then took three long restraint straps and tightly bound them around her large breasts, above and below, and around her slender waist, locking them securely. This completely bound her arms and body together as one, leaving no gaps, making her entire upper body a single unit. "Ah... Master... so tight, I love it!" Ruolan's delicate face was flushed, looking like a ripe red apple, as if a gentle squeeze would draw blood. I chuckled, opened the small door of the dog cage, and said, "Little bitch, crawl in yourself!" The small door of the dog cage was very low, forcing Ruolan to kneel and bury her upper body deeply, relying only on the strength of her legs to slowly move inside. It looked quite arduous. Her delicate head entered the iron cage, eliciting two soft, seductive moans from the depths of Ruolan's throat. But as her upper body was halfway in, I called out, "Stop, little bitch, don't move!" "Ah..." Ruolan let out a soft cry. At this moment, with her slender waist as the dividing line, she was as if stretched across the iron door. She could no longer hold on, and her upper body collapsed forward. Looking at this unconventional and decadent scene, I felt the hardness between my legs, which had already risen at some point, standing erect and trembling slightly in the air. Ruolan's tender, full buttocks were raised high in the air, wriggling slightly. Between her delicate cleavage, her decadent, sexy rear and her wet, muddy pussy were completely exposed to the air, presented to me without reservation. From the folds of her fair, tender anus, a drop of decadent milky white liquid occasionally dripped, looking so alluring. I shook my head fiercely, suppressing the surging thoughts and desires in my heart. I picked up a bundle of hemp rope, unfurled it, and fiercely bound Ruolan's two slender legs. The hemp rope danced between my fingertips, as if alive, winding and binding around Ruolan's jade legs, digging deeply into her tender skin. Soon, her slender legs were bound into a standard M-shaped spread. At this point, Ruolan's two slender legs were tightly bound by the dense hemp rope, her calves pressed tightly against her thighs, unable to separate even slightly. She could only rest on her tender knees, stuck in the middle of the small door, struggling and wriggling. Next, I took the two leather restraint sleeves and slipped them onto her knees, tightly encasing and restraining her legs. As the drawstring was continuously tightened and knotted, Ruolan seemed to have lost her lower legs, displaying a unique sense of incomplete beauty. I slapped Ruolan's full, perky buttocks twice: "Alright, little bitch, you can go in now!" "Yes, Master!" Ruolan replied charmingly. Her entire body crawled on the ground, wriggling slightly, inching her way into the dog cage. "Mmm... ah..." Accompanied by soft, seductive moans, Ruolan finally entered the dog cage and lay panting on the bottom, as if she had exhausted all her strength. I nimbly closed the iron door, locked it with the exquisite small lock, and chuckled, "Little bitch, goodnight. This Master is going to sleep. I have to go to work tomorrow. You enjoy yourself in the dog cage!" "Mmm... okay... Master... goodnight... Master..." It was clear that the intense restraint had pushed Ruolan to the brink of delirium, her speech becoming intermittent. Through the gaps in the dog cage, I saw endless desire and a unique pleasure swirling in Ruolan's eyes, as if veiled by layers of mist, about to condense into water droplets and fall from the corners of her eyes. I brought two powerful mini vibrators, inserted them through the gaps, and forcefully pushed them deep into Ruolan's tender, wet rear and pussy. Without hesitation, I pressed the remote control. "Buzz... buzz..." A series of buzzing sounds came, and Ruolan's soft, seductive moans grew louder. Her entire body writhed and struggled on the bottom of the dog cage. I chuckled, then grabbed the chain around Ruolan's neck, pulled it upwards, threaded it through the bars of the dog cage, and tightened it fiercely. "Heh heh," I chuckled, opening the small door of the dog cage. "Little bitch, crawl in yourself!" The cage door was low, forcing Ruolan to kneel and bury her upper body deep inside. She had to rely solely on her legs to slowly inch her way in, a process that looked quite arduous. Her delicate head poked into the iron cage, eliciting a pair of melodious, seductive moans from deep within her throat. But when her upper body was halfway in, I shouted, "Stop, little bitch, don't move!" "Ah..." Ruolan let out a soft cry. At this moment, with her slender waist as the dividing line, she was caught in the iron door, unable to hold on any longer. Her upper body collapsed forward. Witnessing this unconventional and decadent scene, I felt the hardness between my legs, which had already risen at some point, standing tall and trembling slightly in the air. Ruolan's tender, full jade buttocks were high in the air, wriggling slightly. Between the delicate cleft of her buttocks, her decadent, sexy anus and wet, slick pussy were completely exposed to the air, presented to me without reservation. From the folds of her fair, tender chrysanthemum, a drop of decadent milky white liquid would occasionally drip, looking so alluring. I shook my head fiercely, suppressing the surging thoughts and desires in my heart. I picked up a bundle of hemp rope, unfurled it, and ruthlessly bound Ruolan's two long legs. Strands of hemp rope danced between my fingertips, as if alive, coiling and binding around Ruolan's jade legs. They dug deep into her tender skin, quickly binding her long legs into a standard M-spread position. At this point, Ruolan's two long jade legs were tightly bound by dense hemp rope, her calves pressed firmly against the back of her thighs, unable to separate even slightly. She could only rest on her tender knees, trapped in the middle of the small door, struggling and wriggling. Next, I brought out the two leather restraints and slipped them over her knees, tightly wrapping and immobilizing her jade legs. As the ropes were tightened and knotted, Ruolan looked as if she had lost her calves, exuding a unique, incomplete beauty. I slapped Ruolan's full, perky buttocks hard. "Alright, little bitch, you can go in now!" "Yes, Master!" Ruolan replied charmingly, her whole body wriggling on the ground, inching her way into the dog cage bit by bit. "Mmm... Ah..." Accompanied by a series of melodious, seductive moans, Ruolan finally entered the dog cage, panting heavily on the bottom, seemingly having exhausted all her strength. I nimbly closed the iron door and locked it with a delicate little lock, chuckling, "Little bitch, goodnight. Master is going to sleep. I have to go to work tomorrow. You just enjoy yourself in the dog cage!" "Mmm... Okay... Master... Goodnight... Master..." It was clear that the intense restraint and confinement had pushed Ruolan to the brink of delirium, her speech becoming intermittent. Through the gaps in the dog cage, I saw Ruolan's eyes already brimming with endless desire and a peculiar pleasure, as if veiled by layers of mist, about to condense into teardrops and fall from the corners of her eyes. I brought out two powerful mini vibrators, inserted them through the gaps, and thrust them deep into Ruolan's tender, slick anus and pussy. Without hesitation, I pressed the remote control. "Buzz... buzz..." A series of buzzing sounds filled the air, and Ruolan's melodious, seductive moans grew more intense. Her entire body writhed and struggled on the bottom of the dog cage. I chuckled, then grabbed the chain around Ruolan's neck and pulled upwards, threading it through the bars above the cage and tightening it fiercely. "Ugh... Mmm..." The tightening pressure of the collar brought Ruolan to a slight state of breathlessness, and two unconscious moans escaped her throat. However, I hadn't tightened the chain completely; Ruolan only needed to lift her head slightly to breathe fresh air. Watching Ruolan's breathing become slightly rapid, her eyes filled with intense desire, and her appearance of thoroughly enjoying this state of slight suffocation, I clapped my hands with satisfaction and contentedly returned to the master bedroom to sleep, leaving Ruolan alone in the dog cage in the living room, struggling and writhing, slowly surging towards the peak of pleasure. Faint moans echoed continuously, seeming to drift into the bedroom, transforming into a beautiful lullaby that accompanied me into dreamland. Although I slept alone in an empty room, my heart was filled with a sense of complete happiness, and I felt that even the taste of my dreams was sweet. The next morning, I slowly woke up from my sleep and heard faint voices from the living room. Groggily, I got up and walked into the living room, finding Ruoxi already awake. She was squatting in front of the dog cage, whispering something to Ruolan. Seeing me emerge, Ruoxi looked up, a faint blush spreading across her delicate face. She said crisply, "Brother-in-law, good morning. You're up?" "Mmm..." I nodded. Seeing that it was still early, I plopped down on the sofa. Looking at Ruoxi's graceful figure, a subtle tremor began to brew within me. "Why are you up so early?" "Heh heh... I couldn't sleep, so I got up. It's a good thing I got up early, or I wouldn't have discovered that you locked my sister in this cage all night. You're such a pervert!" Ruoxi rolled her eyes. Although Ruoxi still called me a pervert, her tone and voice were fundamentally different from before. It seemed to have shifted from disgust and contempt to an indescribable charm and coyness, like a girl in love playfully calling her boyfriend a "big bad guy." I rolled my eyes and pretended to be fierce. "Heh... you little brat, how dare you call your brother-in-law a pervert? Believe it or not, I'll tie you up and send you in to stay with your sister!" "Hmph... Come on then, I'm not afraid of you!" Ruoxi's delicate face flushed even deeper, her head held high, provocatively saying, "It's not like I haven't been tied up by you before. This trick of yours doesn't work anymore, heh heh... Na-na-na..." Ruoxi stuck out her tongue at me and made a face. "I'm not talking to you, you big pervert. I'm going to wash up, hmph..." With that, she entered the bathroom like a proud swan. I shook my head with a wry smile and squatted down in front of the dog cage. Ruolan turned her head slightly, meeting my gaze through the bars, her eyes filled with a happy smile and adoration. She murmured, "Master, good morning. Little bitch greets you!" "Little bitch Ruolan, how was your night? Satisfied?" I asked with a chuckle. "Did you miss Master?" "Heh heh... You know what's good for you. Now, kneel and welcome your master?" I slowly walked up to Cheng Yao. Cheng Yao trembled all over, her eyes filled with an endless, indescribable gleam. Clearly, she was thrilled by the changes in me. She immediately stood up from her chair and obediently knelt before me, her upper body prostrate on the floor. She said respectfully, "Number 4, little bitch, greets Master. Please, Master, train me!" Looking at Cheng Yao like this, a subtle realization dawned on me. Despite being a company president, she was, at her core, just a woman, yearning for a man stronger than her to completely conquer her. I pulled open the drawer of Cheng Yao's desk and found a set of leather restraints. My blood immediately began to boil. "Little bitch, take off your clothes!" "Yes, Master!" Cheng Yao replied obediently and began to undress without hesitation. In a short while, she was completely naked, her tender body fully exposed before me. I took out the leather restraint set and put it on Cheng Yao's exquisite body piece by piece. Soon, she was transformed into a stunningly beautiful and sexy leather-clad bitch. At this moment, Cheng Yao's arms and legs were tightly folded and bound by the leather restraints, leaving only her elbows and knees exposed. The smooth black leather, under the light, exuded an intensely decadent and beautiful sheen. I had tightened the drawstrings on the sides completely, leaving her no room to move, forcing her to kneel on her elbows and knees, trembling slightly. She looked even more like a bitch than a real one. I picked up a large gag and shoved it forcefully into Cheng Yao's mouth, sealing her tender lips tightly and completely stripping her of her ability to speak. All she could do was emit a series of melodious, alluring, and meaningless moans from the depths of her throat, echoing in the office. Finally, I took a leather collar and fastened it around Cheng Yao's neck, tightening it securely. Pulling the long chain attached to the collar, I led her towards the lounge. Cheng Yao crawled obediently behind me. Taozi, writhing on the large bed, saw Cheng Yao behind me and her eyes widened in surprise. She stared intently, her eyes filled with an endless primal desire and a glint of eagerness. I found a large butt plug and brought it to Cheng Yao's tender rear. Cheng Yao immediately dodged, wriggling on the floor, emitting a series of melodious moans from her throat. I understood immediately and chuckled, "Heh heh. You haven't been cleaned, have you? Wait, today, your Master will personally clean you thoroughly!" "Mmm..." Cheng Yao's legs went weak, and she collapsed onto the floor, panting heavily. Her entire body trembled slightly, and clear fluids pooled on the floor. My eyes darted, and an idea struck me. I walked to the edge of the large bed, scooped up Taozi, and carried her into the bathroom. I sat her on the toilet and then used a hemp rope to tightly bind her tender body to the toilet tank. I clapped my hands, my eyes filled with an endless primal desire. Now, Taozi sat on the toilet, her upper body pressed tightly against the water tank behind the toilet. Her legs were folded high and spread wide, secured by the hemp rope. The hem of her tight skirt had already been lifted to her slender waist, exposing her tender pussy completely to the air, already glistening wet. Clear fluids flowed incessantly down her crack. "Ah... Mmm... Master... so shameful... oh..." Taozi's pretty face was flushed crimson, her eyes hazy. Her entire body writhed slightly on the toilet, and a series of melodious, alluring moans emanated from her throat. I left the bathroom and slowly pulled Cheng Yao inside. As Cheng Yao crawled into the bathroom, she saw Taozi tightly bound to the toilet. Her eyes were filled with overwhelming primal desire and a strange pleasure. The fluids from between her legs gushed out like a broken dam, flowing uncontrollably. I chuckled, "Heh heh," and removed the large gag from Cheng Yao's mouth. I immediately brought it to Taozi's lips and, without any preamble, stuffed it into her mouth. The gag was still covered in a large amount of Cheng Yao's saliva, mixed with Taozi's own. It dripped down the corners of her mouth, a scene filled with infinite, extreme allure and decadence. Looking at the two beautiful women before me, one bound and wrapped in hemp rope, the other encased in leather restraints, each with their own unique charm, yet both radiating endless allure, I kicked Cheng Yao's plump, perky buttocks. "Go, serve your good sister!" "Ah... Yes... Master!" Cheng Yao let out a long, melodious moan from the depths of her throat. She crawled a few steps on the floor, her pretty head moving towards Taozi's legs. "Mmm... Mmm..." Taozi's pretty face was covered in a blush. She shook her head constantly, her entire body struggling and writhing on the toilet, emitting a series of melodious, alluring moans from her throat that echoed in the small bathroom. Cheng Yao's pretty head nestled between Taozi's tender thighs. Without hesitation, she extended her nimble, soft, and fragrant tongue, licking and sucking Taozi's wet and muddy pussy. "Mmm..." Cheng Yao trembled all over, too ashamed to open her eyes. A high-pitched, melodious moan escaped from her throat. Her entire body shivered under the tight restraints, while I detached the showerhead, attached a long, flexible hose, adjusted the water temperature, and turned it on, directing it towards Cheng Yao's tender rear. "Ah..." As the warm water gushed in, Cheng Yao let out a melodious cry. However, her nimble, fragrant tongue still refused to leave Taozi's wet pussy, continuously licking, sending waves of tingling pleasure to Taozi.
