1490 teased, "That's fantastic!" Lu Yun silently exclaimed in his heart. Clearly, the sensitive body of Fei Yan had been conquered once again by him. Though she spoke softly, saying she didn't want to continue, her little waist began to move instinctively, swaying from side to side. The subtle opening between her buttocks only added to Lu Yun's pleasure. He couldn't help but press deeper into her twice, and at that moment, Fei Yan emitted a soft, melodic sigh—like a nightingale's song—full of the kind of charm that could stir endless desire. Lu Yun felt even more aroused. Facing such a sensitive girl, whose body, face, and especially her most precious "Water Curtain Cave" were all truly exceptional, he knew that in a few years, as she matured further, her allure would only grow even more exquisite. Lü Yun, feeling as though he were enjoying a fine meal, maneuvered his member in and out of Feiyan's waterfall cave, and within just a few minutes, heard Feiyan softly exclaim, "Cloud brother, I... I'm coming again, coming again—so comfortable..." Sensing Feiyan's tight entrance firmly enclosing his younger brother, Lü Yun knew that Feiyan was indeed about to reach her fourth climax, and so he quickened his pace, adjusting the sensitivity transmitted through the bird pole, and murmured, "Yan'er, let's go together." Immediately, Feiyan whispered, "Brother, I... I can't hold on anymore—I'm absolutely delighted..." Her body then trembled and hesitated as if in spasm, reaching another peak. Lü Yun swiftly increased his intensity and then called out, "Yan'er, I'm about to climax too." Much like Feiyan, Lü Yun suddenly shivered, and a steady stream of rich, white essence poured into Feiyan's narrow entrance. "It's so hot!" "Feiyan lay on the bed, murmuring softly. After releasing once more, Lu Yun bent down and picked her up, smiling gently, "Yan'er, isn't it comfortable?" Feiyan nodded, blushing deeply. "Do you find the front position more comfortable, or is the current one from behind equally pleasant?" With Lu Yun still in a state of excitement, he whispered tender words into Feiyan's ear. "Both are comfortable," Feiyan said, then lowered her head slightly. "Haha, this time we're short on time, so I haven't had much opportunity to fully enjoy the benefits of this position. When we have more time, Cloud Brother will surely make you discover that each change of position brings a different sensation." Lu Yun smiled softly. Feiyan's cheeks flushed, gently nodded, but then suddenly remembered something, her expression becoming tense. "Cloud Brother, I... did I make a lot of noise just now?" Lu Yun was stunned, saying, "Good, I think it wasn't too loud. Anyway, every time you call out, it makes me feel more and more itchy, more and more eager to use my bird pole to poke at your bird nest!" "Ah, Yun-gong, tell me, actually—did you call out loudly? If you did, how would I face going out to help Xiao Ying and the others?" Fei Yan looked tense, her expression completely genuine. Her delicate face had even slightly distorted from such deep concern. "Alright, I'm not teasing anymore. Yan called out beautifully, but I promise you, no one outside will hear a single sound," Lu Yun said seriously, setting aside his playful tone. Upon hearing this, Fei Yan's heart immediately settled. She softly replied, "That's wonderful, Yun-gong. You've done your part now. Let's go out and help—every bit of help counts." They lingered a little while longer, and Lu Yun felt it was time to go. He gently removed the bird staff from Fei Yan's nest, then found a handkerchief to clean both of them, and quickly dressed before joining Fei Yan and walking out together. The break period had only lasted about ten minutes. When Lu Yun and Fei Yan stepped out of the inner room, few students remained at the convenience store buying items. Fei Yan felt a great relief, yet she suddenly noticed that the eyes of her sisters were full of amused curiosity, which made her feel tense again—though more so in a shy way than in actual anxiety. Thinking back to the over an hour they had spent together in the inner room, Fei Yan felt deeply embarrassed and unable to meet the gaze of her sisters. Lu Yun appeared quite composed, finding a chair and settling down. His gaze swept continuously over the young girls, and when he saw Shi Yu, the two exchanged a warm smile—also catching a bright, glowing intensity in Shi Yu’s eyes. Lu Yun knew instantly that Shi Yu must be soaked through, not just in the sense of being wet, but also that every girl in the room, except Fei Yan, had been thoroughly drenched. He could be absolutely certain of this. Once the only students in the convenience store had left, Shi Yu stepped out from behind the counter and grabbed Fei Yan’s hand, teasing, “Fei Yan, how did you feel? Didn’t I tell you? This troublemaker has absolutely no shortage of talent in that department.” Fei Yan had no choice but to stammer, unable to articulate her feelings in response to Shi Yu’s question. “I’m not sure, actually—we didn’t do much.” “Pah, we all heard your cries, didn’t we?” "Saying this, Shi Yu playfully imitated Fei Yan's voice, whispering softly, 'Yun-ge, I'm not going to last anymore—push harder, go deeper... Did you just say that?' At that moment, Fei Yan was so embarrassed she had no words. She had deliberately kept her voice low, trying not to make a sound, yet her sisters had still heard her. She didn't know whether Shi Yu and Lu Yun would call out during their intimacy, but in Fei Yan's mind, if she uttered such words, her sisters would surely think her very indecent. As this thought crossed her mind, tears welled up in her eyes, and she was on the verge of crying. 'Fei Yan, don't listen to Shi Yu's nonsense—we didn't hear a thing!' Xiao Ying, seeing Fei Yan about to cry, immediately pulled Shi Yu aside, and the other sisters gathered around to confirm that they hadn't heard her calls. Yet in Fei Yan's heart, a shadow of doubt remained—how could Shi Yu have remembered every word so precisely if they hadn't actually heard her? The more the sisters reassured her, the more uneasy Feiyan felt. "Feiyan, I didn't lie—I truly didn't hear your voice. What I said was just something I'd say while with Lu Yun, merely to impress you." Watching the sisters comfort her, Shiyu realized she had gone a bit too far and quickly stepped in to soothe her. Feiyan glanced at Shiyu. In truth, she didn't hold any grudge against her. If she had to be honest, she was actually grateful to Shiyu. Without Shiyu's encouragement, she might never have managed to fully merge with Lu Yun.
