Before long, school started. Despite the intense study life of senior year, Sicheng still frequently visited Zou Yan in his spare time. At the same time, Sicheng also began to pay attention to the female classmates and teachers around him.

He Hong was Sicheng's classmate. Since junior high, they had been the group leader and vice-leader of the biology interest group, respectively. They both had keys to the biology lab and often did experiments together.

Shortly after school started, Sicheng accidentally discovered a bottle of medicinal ether in the medicine cabinet in the biology lab, and a plan formed in his mind.

On the afternoon of the second Saturday, Sicheng and He Hong went to the biology lab to conduct a bacterial inoculation experiment. While He Hong was engrossed in her work, Sicheng quietly soaked a cotton swab in ether, went behind her, and suddenly covered her mouth and nose. Caught off guard, He Hong struggled briefly before being anesthetized. Sicheng half-dragged, half-carried He Hong to the sterile room next door and laid her flat on the white tiled floor.

Just as Si Cheng removed He Hong's top, he heard the sound of a key being inserted into the lock to open the door. Si Cheng quickly hid behind the door. Entering was their tutor, Miao Li, wearing a white shirt and a dark suit skirt that tightly hugged her full, rounded hips.

Upon entering, Miao Li noticed He Hong lying half-naked on the sterile room floor. Without even taking off her high heels, she rushed into the sterile room and crouched down to see what had happened. Si Cheng emerged from behind the door, silently approached Miao Li from behind, tightly covered her mouth and nose with cotton swabs, and tackled her to the ground, pinning her down. Miao Li, caught off guard, struggled, but her body quickly went limp. She didn't even see who her attacker was before being paralyzed, collapsing onto He Hong.

Si Cheng sat beside He Hong and Miao Li, looking at one and then at the other. One was an innocent young girl, the other a mature and voluptuous beauty. He was momentarily unsure which to make his move on first. Finally, Si Cheng decided to have sex with Miao Li first, after all, he had never tried such a mature and alluring middle-aged woman before.

Si Cheng dragged Miao Li, who was lying on He Hong, to the side. Fearing she might wake up, he stuffed two small wads of cotton soaked in ether into Miao Li's nostrils. Then, with excited anticipation, Si Cheng removed her white shirt and dark suit skirt. Thus, Miao Li was left only with a bra, panties, flesh-colored elastic stockings, and black high heels. The afterglow of the setting sun cast a golden glow on Miao Li's mature and voluptuous body. Her high breasts, deep cleavage, rounded buttocks, and plump thighs were all so different from the bodies of the young girls Si Cheng had ever touched. This mature, voluptuous body, instantly evoking images of carnal desire, ignited a powerful desire in Si Cheng to possess, conquer, and invade.

Si Cheng took a deep breath, trying to suppress his nervous excitement, controlling his trembling fingers as he pulled off the only thing on Miao Li's body—a bra that was barely covering her—and her thin white panties. Without even removing her stockings and high heels, he spread her legs, supported them with his arms, and thrust his penis deep into her vagina.

Having the experience of having sex with Wang Lin and Zou Yan, Si Cheng was more composed this time. During the act, Si Cheng felt that Miao Li's vagina was more lubricated and slightly wider than the previous two. While penetration wasn't easy, it became increasingly smooth, a unique and intoxicating pleasure. Throughout the entire process, Miao Li remained unconscious, but her vagina became increasingly lubricated, constantly releasing copious amounts of lubricating fluid. Si Cheng ejaculated after more than half an hour, feeling extremely satisfied.

After ejaculating, Si Cheng immediately got off Miao Li and went to He Hong's side, eagerly stripping her of all her clothes. He Hong had just turned eighteen that year, her body just reaching maturity, appearing petite and delicate. Her breasts were high and full, with pink nipples like two tiny flower buds. Between her legs was smooth as jade, her vulva like a pearl oyster half-closed, appearing innocent and tender.

Si Cheng parted He Hong's legs, pressed his body against hers, and forged ahead, overcoming obstacles and hardships. Finally, Si Cheng carved a path and thrust into He Hong's vulva. He Hong had already been awakened by Si Cheng's actions. She struggled in agony before his penetration, helplessly twisting her frail body.

Just as Si Cheng broke through her last line of defense, she couldn't bear the tearing pain, letting out a sharp scream before fainting. He Hong's piercing scream stirred an unprecedented excitement in Si Cheng, causing him to ejaculate uncontrollably.

He Hong's agonizing scream, a farewell to her virginity, simultaneously roused Miao Li from her unconsciousness. She struggled to sit up, feeling heavy, exhausted, and powerless. She looked up, her gaze meeting that of the naked, unconscious He Hong and Si Cheng, who was getting off He Hong. She looked down at her own naked body and the filth between her legs, and understood everything.

Before Miao Li could speak, Si Cheng pounced on her again. Miao Li instinctively struggled slightly, her lips parting slightly as if to speak, but Si Cheng pressed his lips firmly against hers. Miao Li's eyes widened, making muffled sounds through her nose, but she quickly stopped struggling, spreading her tightly closed legs and fully opening her body to Si Cheng.

Si Cheng used his arms to lift Miao Li's legs, his hands supporting her plump, smooth buttocks, lifting them off the ground. He thrust his body forward, penetrating her vagina deeply, then pressed her body down, pushing his penis to its deepest point, withdrawing halfway, then lifting her buttocks off the ground again for another round of penetration. He repeated this with large, forceful thrusts, constantly slapping against Miao Li's body, making a slapping sound. With each movement, Miao Li couldn't help but moan "Oh!" or exclaim "God!" Her body gradually began to sway in sync with Si Cheng's thrusting. Their actions were both greedy and almost frenzied.

When Si Cheng and Miao Li finally slid down from the peak of passion and ecstasy, they discovered that He Hong, who had already woken up, was stunned by their actions. Her cheeks were flushed, her body limp and powerless, and she had collapsed uncontrollably to the ground.

Seeing an opportunity, Miao Li gently nudged Si Cheng, signaling him to seize the moment and go to He Hong's side.

Si Cheng pounced on He Hong and began having sex with her again. He Hong's face was flushed, her body limp, letting Si Cheng do as he pleased. At this moment, she no longer felt pain but pleasure. Miao Li watched the whole process.

In this way, Si Cheng had sex with two women in one afternoon. After that, Si Cheng, He Hong, and Miao Li often used the laboratory to meet and have sex, and sometimes Miao Li would take them to her house when no one was home.

At first, He Hong was somewhat shy and unwilling to give in easily, but eventually, after Miao Li's careful persuasion, she slowly submitted to Si Cheng. As the oldest of the three, Miao Li was responsible for providing contraceptives and the place for sex.

Si Cheng's relationship with the two women remained undetected, continuing intermittently.
