Chapter 1446: "Hehe, Sister, you've been so enthusiastic—looks like Zhang has been doing nothing to satisfy you these past few days," Lu Yun said with a cheerful smile while moving around. This guy, after going through a series of well-acquainted women recently, has managed to stay calm and composed, breathing easily and moving with the ease of someone strolling through a garden—completely at ease even when handling just one woman like Liu Yun. Yet Liu Yun herself is finding it hard to keep up, experiencing a relentless surge of intensity while mentally gasping: "This young man is truly getting better and better! In just a few days, he's already surpassing his previous performance. How could he have managed to leave me unsatisfied?" Hearing Lu Yun's playful remarks, Liu Yun murmured softly, "Lu Yun, you've been playing tricks on me, even going on about things with me. How do you know Zhang hasn't satisfied me? He's far more skilled than you—oh! Just lighten up a bit, you're being so rough!" Lu Yun chuckled, having already subtly activated the Yin-Yang Expansion and Contraction Technique. Yet, compared to that, he preferred the sensation of his abdomen gently colliding with Li Yun's firm, rounded buttocks. So, even as the technique flowed, Lu Yun unconsciously moved his body in a rhythmic forward-and-backward motion, savoring the remarkable elasticity radiating from Li Yun's broad, smooth buttocks. "Who's better?" When doing this, Lu Yun naturally knew that being openly expressive would further excite the woman, making her even more aroused. With that, Lu Yun's movements grew even more vigorous. Liu Yun gasped in pain, breathless and exclaimed, "You're amazing! You're a hundred times better than your brother Zhang! Oh, my dear, you've really worked me to the bone—both exhausting and delightful. So comfortable, Xiao Yun, could you please be a little gentler? I'm afraid my lower part is going to be pierced through, oh!" Under Lu Yun's relentless thrusts, Liu Yun's voice grew increasingly fragmented and high-pitched. As her body grew more and more excited, she found herself reaching that peak of bliss time and again, her cries growing louder and louder until she completely forgot she was in Zhang Ning's room. "Sister, please speak softly—otherwise, if Miss Ning hears us, we're both in trouble." Fortunately, it was still class time. If it were after school hours, Liu Yun's cries would have been impossible to ignore as anyone passing by would surely have heard. Prompted by Lu Yun, Liu Yun suddenly realized what was happening, her initial loud cries instantly turning into a low, almost sobbing sound. There was nothing more unbearable than experiencing such intense pleasure yet being unable to express it through sound. Although her vocalizations softened, her physical responses did not diminish—they actually intensified due to the effort of suppressing her cries. With every thrust from Lu Yun, Liu Yun felt an unparalleled sensation of pleasure. Liu Yun didn’t want to cry out, fearing that Zhang Ning might hear, yet she simply couldn’t endure the continuous wave of pleasure. "Little Yun, why haven’t you finished yet? I’m completely exhausted now. Why don’t you stop for a moment? By now, Xiao Ning should have returned. If she finds us doing this in the room, it might not be good for your relationship in the future." After being once again brought to her peak state by Lu Yun's intense impact, Liu Yun finally found herself unable to hold back and spoke out. This young heir has grown increasingly formidable—she simply couldn't manage on her own anymore. As she spoke, a rather strange thought surfaced in her mind: what if, when she and Lu Yun were together, she didn't have to secretly do it, but could instead share the experience with Xiao Ning as well? That would be wonderful. Yet, this thought only just emerged and was swiftly extinguished by Liu Yun, who quietly scolded herself for being so unseemly. After all, she had already been unfaithful to her husband by secretly sharing this with Lu Yun—now she was even thinking of involving Xiao Ning in the affair. When had she become so shameless? Lu Yun had no idea that, in such a brief instant, Liu Yun had come up with such a ridiculous notion. Upon hearing this, he continued sprinting, smiling cheerfully and said, "Sister-in-law, you're being rather unkind. You've completely taken over the scene, yet you leave me standing here, breathless and tense. Won't you end up making me feel uncomfortable, to the point where I can't rely on my super-ultimate staff anymore?" Liu Yun laughed and scolded him, yet she knew it was indeed difficult to stop Lu Yun at this moment. She herself was well aware of her condition—after a series of intense moments, her body had reached its limit. Her legs felt weak and limp, with no strength left at all. It was only thanks to Lu Yun holding her steady during the sprint that she hadn't collapsed already. "Then hurry up, I'm afraid Xiao Ning will return and find out about us. After all, what we've been doing is quite private. If discovered, we'll both be in serious trouble." "Yuanyun sighed helplessly and then clenched her teeth to bear Lu Yun's relentless pressure. Lu Yun replied, knowing time was running out—he now needed to fire off all his shots as quickly as possible. While they each fought their own battles, the door suddenly rang. Yuanyun jumped with genuine fear—this time, she truly felt herself about to collapse. "Sister-in-law, open the door!" came Zhang Ning's voice from outside, full of concern. "Ah, here she comes!" Yuanyun quickly turned to see Lu Yun still charging forward, speaking softly, "Xiaoyun, this time it's really over. Please, hurry and secure your gun—Zhang Ning is here." As she spoke, Yuanyun tried to force herself to her feet to open the door for Zhang Ning. But at that moment, Lu Yun wrapped his arms tightly around her waist, and his lower body pressed with increasing force, delivering several strong impacts. Faced with Lu Yun's sudden intensification of pressure, Yuanyun could no longer hold back and cried out. "Sister-in-law, what's wrong? Hurry and open the door!" "Zhang Ning outside didn't know what was happening inside. He was pacing anxiously, shouting. When he left, his sister had specifically said she'd take care of Lu Yun. Now the door was locked from the inside, and suddenly his sister called out—was it possible that a conflict had arisen between his sister and Lu Yun, and Lu Yun had ended up hitting his sister? "Lu Yun, please open the door—don't rush!" Zhang Ning's urgent voice rang out again. "Ning姐, I'm coming right away to open the door for you," Lu Yun replied while stepping up his pace, whispering to Liu Yun, "Sister, I'm about to explode—I'm holding on just a little longer." Liu Yun had nearly been scared senseless when she first called out, and now, upon hearing Lu Yun's words, she rolled her eyes and murmured in mild annoyance, "You kid! You're about to scare my sister to death. Hurry up and finish it—otherwise Little Ning will start suspecting something." As he spoke, he suddenly felt the massive, blazing surge within his body swell dramatically, as if rising like a colossal pillar, followed by a wave of heat that swept over him, warming Li Yun so much that she couldn't help but hum comfortably again. Finally released, Lu Yun took a deep, steady breath, then quickly returned his pistol to his crotch, positioned Li Yun half lying on the bed, and rushed to open the door for Zhang Ning.
