**************** 　　... 　　Although Cheng Ming himself wasn't worried—it seemed like a case of the emperor not being anxious but the eunuch being anxious for him— 　　for Xiao Yue, her son Cheng Ming's college entrance exam was crucial. His poor grades were unacceptable. Therefore 　　, under her strong insistence, Cheng Ming had no choice but to accept his mother's 　　arrangement to hire several tutors for him. 　　Of course, Cheng Ming would never admit that seeing the female teachers' photos also aroused his lust. 　　For someone with the ability to change the world with a snap of his fingers, perhaps everything was just a game. He 　　didn't know what he truly wanted, nor did he understand the meaning of it all. With everything carefree, 　　he could only try his best to make himself happier and make the game more exciting. 　　For example, the physics teacher who came to tutor Cheng Ming today had prepared many excellent lesson plans for him. 　　Cheng Ming sat quietly waiting. Not long after, he heard the doorbell ring, knowing that the teacher had arrived. 　　Upon opening the door, a vibrant young woman stood outside. She was even more beautiful and had a better figure than in the photos 　　, which greatly pleased Cheng Ming. He couldn't help but scrutinize her a few more times, his gaze somewhat aggressive. The woman didn't seem to 　　mind, standing there gracefully and allowing him to examine her. She smiled at Cheng Ming and greeted him, "Hello, 　　are you Cheng Ming?" 　　"Ah, yes, yes," 　　Cheng Ming replied, slightly flustered by the woman's sudden interruption. However, he quickly composed himself, as 　　everything was still under his control. 　　"My name is Liu Xiaoqian, and I'll be your physics teacher for the next month," 　　the woman, Liu Xiaoqian, said, giving Cheng Ming another bright smile that made his heart flutter 　　. 　　"Please come in, teacher. Let's go upstairs for class," 　　Cheng Ming said, quickly opening the door and inviting her in. They walked together upstairs to Cheng Ming's room. 　　After entering, Liu Xiaoqian carefully closed the door, making sure it was completely shut. Then, she turned to Cheng Ming and 　　took off her top. Surprisingly, she wasn't wearing anything underneath, 　　revealing a rather alluring young body to Cheng Ming. 　　"Where should I put my clothes?" 　　Liu Xiaoqian held the clothes in her hands, smelling them. Although she was only wearing white cotton socks, 　　she didn't feel awkward and asked Cheng Ming seriously. 　　Cheng Ming thought for a moment, "Just leave them by the door. We rarely have guests anyway." 　　Liu Xiaoqian nodded, put the clothes down, and followed Cheng Ming into the room. 　　In Cheng Ming's mind, tutoring someone's home required removing all clothing as a sign of respect; 　　to avoid dirtying the floor, the socks could be left behind. 　　The two sat down at the table. Liu Xiaoqian flipped through Cheng Ming's textbooks, asking as she looked, "You 　　should have finished these books in school. Which parts do you feel you're weak in? There's not much time left before the college entrance exam, so there's not enough time 　　to go through them all. I'll focus on a few weak areas." 　　"Hmm... I don't understand much about force and motion. How about we start with that?" 　　Cheng Ming thought for a moment and said. 　　Liu Xiaoqian naturally didn't object, saying softly, "Okay, I brought some teaching aids with me this time, so it's 　　perfect for that." "Speaking of force and motion, there are many things to talk about. Let's start with 　　elasticity 　　, following the order in the books ." 　　Liu Xiaoqian picked up the book and began to speak fluently. 　　"So, do you know what elasticity is?" 　　Cheng Ming thought for a moment, then shook his head, indicating he didn't quite understand. 　　"The condition for elasticity is that elastic deformation must occur." 　　Liu Xiaoqian smiled slightly, lifting her breasts. "Come on, hold my teaching aids with your hands." 　　Cheng Ming did as she said, reaching out and gently kneading Liu Xiaoqian's breasts. 　　"Hmm...that's it." 　　Feeling the waves of stimulation coming from her chest, Liu Xiaoqian couldn't help but close her eyes. "When you knead it hard with your hands 　　, you're actually applying inward pressure to the teaching aid, causing it to deform and generate elasticity. Now, 　　can you feel the elasticity of the teaching aid against you?" 　　"I can feel it, it's so amazing!" 　　Cheng Ming exclaimed, increasing the kneading force and playing with the pair of small but beautiful breasts in his hands. 　　Liu Xiaoqian forced herself not to make any strange noises and continued to explain, "Within the limits of elasticity, 　　the greater the pressure your hands exert on the teaching aid, the greater the elasticity you experience." 　　"Haha, I see, teacher, I understand!" 　　Cheng Ming said excitedly, kneading the breasts even harder. 　　"Hmm...I understand...that's good." 　　Liu Xiaoqian seemed uncomfortable with the strange sensations emanating from her chest, but she still managed a 　　smile and continued explaining to Cheng Ming, "Then...then let's continue...friction." 　　At Liu Xiaoqian's instruction, Cheng Ming sat upright in the chair, and Liu Xiaoqian stretched out her feet, 　　clad in white cotton socks, and began rhythmically stroking Cheng Ming's penis. 　　Cheng Ming enjoyed Liu Xiaoqian's footjob, almost moaning with pleasure. Liu Xiaoqian continued, 　　"Relax, carefully feel this sensation." 　　Her white-socked feet rubbed and slid against his hot, massive penis, like a beautiful woman dancing around a pillar, each stroke...

The pillar's teasing made Cheng Ming's heart itch unbearably. Liu Xiaoqian seemed to sense Cheng Ming's feelings, and her movements
quickened.
"How does it feel different now compared to before?"
Liu Xiaoqian asked, increasing the pressure.
"It feels more comfortable than before, it's gripping tighter,"
Cheng Ming thought for a moment and said.
Liu Xiaoqian nodded in satisfaction. "One of the factors that determines friction is pressure. The greater the pressure my toy puts on your
genitals, the greater the friction between them. Do you feel anything else?" "Uh...so good, I think I'm about to ejaculate," 　　Cheng Ming's penis was already eagerly awaiting
its release . 　　"Ha, don't rush, wait a moment," 　　Liu Xiaoqian hurriedly took off the cotton sock on her right foot, pulled the sock over Cheng Ming's penis, and slipped it 　　inside the sock, which still retained her body heat. Only then did she say with relief, "You can cum now." 　　Cheng Ming, who had been unable to restrain himself any longer, shuddered upon hearing this, and large gushes of semen spurted out. The rapid 　　stream of semen caused the white cotton sock to rise high several times before slowly falling back down. By the time he had completely ejaculated, one sock was soaked 　　through. 　　Seeing that Cheng Ming had finished, Liu Xiaoqian happily removed the cotton sock from his penis and solemnly put it 　　away, intending to enjoy it later. Right now, the most important thing was to attend class. 　　"Now that we've discussed the effect of pressure on friction, let's talk about another factor: the smoothness of the contact surface 　　." 　　Liu Xiaoqian said, taking out a roll of stockings from her bag, putting one on her right foot, and continuing to 　　tease Cheng Ming's large penis, which had just ejaculated. 　　"Oh..." With Liu Xiaoqian's actions 　　, Cheng Ming gasped in pleasure as she 　　felt the silky silk stockings on his left and the soft cotton stockings on his right . 　　Seeing the blissful expression on Cheng Ming's face, Liu Xiaoqian was very satisfied with her work and laughed, 　　"Did you feel it? Is the friction different on the left and right?" 　　"Hmm, it's a little less on the left," 　　Cheng Ming replied after thinking for a moment. 　　"Good, that's about it for friction. What you just experienced was 　　the difference between cotton and silk fabrics. Now, try to feel the sensation of human skin and see if you can calculate its 　　coefficient of kinetic friction." 　　Liu Xiaoqian smiled and pulled open the stockings. Cheng Ming, understanding, inserted his penis into the stockings, keeping it close to the edge of her thigh. 　　Liu Xiaoqian released her, and the tight stockings confined his penis inside. Cheng Ming had to exert considerable force to move it 　　slightly. 　　Cheng Ming stood behind Liu Xiaoqian, his left hand supporting her waist, his right hand lifting her beautiful leg. He adjusted the 　　angle and rubbed his penis between the stockings and her legs. 　　Liu Xiaoqian could only stand on one leg, stroking Cheng Ming's large penis through the stockings. 　　"Hiss... indeed... much tighter than before," 　　Cheng Ming exclaimed, feeling the wonderful sensation of his penis against her stockinged legs. "But human skin 　　isn't as smooth as stockings, so why is the friction greater?" 　　"Hehe, the stockings constrict your penis, applying a pressure perpendicular to the shaft. Friction 　　= coefficient of kinetic friction × pressure. If the friction difference isn't too large, a significant increase in pressure 　　will definitely increase the friction," 　　Liu Xiaoqian explained earnestly, enduring Cheng Ming's thrusts. 　　Oh, I see. Cheng Ming understood and was very happy. With persistent effort, he ejaculated a 　　stream of semen, all of it filling the stockings covering Liu Xiaoqian's jade-like legs. 　　"Ah..." 　　Startled by the hot semen, Liu Xiaoqian gasped, but quickly regained her composure 　　and continued her work as a tutor. "That's all for today. Now, let's assign 　　some homework." 　　Cheng Ming reluctantly pulled his penis out of Liu Xiaoqian's stockings and asked, "What's the homework?" 　　Liu Xiaoqian smiled and replied, "One at a time. The first question is: Insert your penis into the teaching aid and 　　repeat the insertion-withdrawal motion indefinitely. Find the friction force between your penis and the teaching aid." 　　"Ah, this question is a bit difficult," 　　Cheng Ming said with a pained expression. 　　"It's difficult, but you have to do it. It's a necessary process in learning," 　　Liu Xiaoqian said seriously, her face stern. She spread her legs and began to guide Cheng Ming. "It's actually very simple 　　. You just need to put the tip of your penis against my little hole and press down hard... Ah... Good... 　　So big." 　　Liu Xiaoqian was explaining the key points when Cheng Ming, who had been obediently following the steps, suddenly 　　thrust in forcefully, plunging his penis, which was being warmed up at the entrance, into her hole and pumping hard. 　　"Hmm... You... How could you..." 　　Liu Xiaoqian wanted to say, "How could you suddenly insert it like that? You're not following the script at all, it startled me," but 　　she had clearly asked Cheng Ming to insert it, so saying that wouldn't be appropriate. She was momentarily speechless. 　　"Am I doing well, teacher?" 　　Cheng Ming slowed down his thrusting at Liu Xiaoqian and asked with a lewd grin. 　　Liu Xiaoqian felt the force of Cheng Ming's thrusts, experiencing a continuous flow of pleasure. She could also feel that the friction was relatively 　　even, indicating that he had a good grasp of rhythm. She praised him, "Not bad, it seems you've been learning very diligently 　　... ah..." 　　Taking advantage of Liu Xiaoqian's relaxation after praising him, Cheng Ming's movements, which had slowed down, suddenly intensified 　　, thrusting even more rapidly than before. His strong body pressed down on Liu Xiaoqian, slapping her repeatedly. Liu Xiaoqian 　　was momentarily lost in the pleasure. 　　"Ah... you... you're cheating... ah... you can't do this... you can't do this..." 　　Under the storm of attacks, Liu Xiaoqian incoherently accused Cheng Ming, her reproaches interspersed with moans 　　. Instead of putting pressure on Cheng Ming, her words only aroused him further. 　　"Hehe, teacher, you didn't say I couldn't do this," 　　Cheng Ming smiled slyly, making Liu Xiaoqian suddenly want to beat him up. 　　Liu Xiaoqian was about to speak when she felt a sudden heat in her vagina, and instantly a torrent of semen erupted. Cheng Ming

His penis was pressed against her cervix, pumping as much fluid as possible inside. Under such intense stimulation, Liu
Xiaoqian's mind went blank for a moment. She only knew to subconsciously stretch out her legs and firmly lock them around Cheng Ming's waist, making the semen
flow even more rapidly.
She didn't know how much time had passed before Liu Xiaoqian came to her senses and found herself being carried to the sofa by Cheng Ming. It turned out that
her legs had been wrapped around Cheng Ming's waist the whole time, so his penis remained erect and
inserted inside her.
"Teacher, I've finished reading this question,"
Cheng Ming said with a smile, teasing Liu Xiaoqian's nipples with his hands.
Liu Xiaoqian frowned, not wanting to let this wretched boy off so easily. A thought flashed through her mind, and she said, "You
didn't read the question carefully; you didn't follow the instructions!"
"Hmm? What's wrong?"
Cheng Ming asked, puzzled.
Seeing his troubled expression, Liu Xiaoqian's mood instantly improved. She continued, "There's another condition for this problem
: you must insert your penis into the uterus during ovulation, and ejaculate twice in each of five different positions
."
"Why is that? I understand positions—different positions have different pressure and friction—but why
during ovulation?"
Cheng Ming questioned.
"Ha, this is for future preparation. We'll be researching the friction of a pregnant woman's vagina against a penis in the future, so
you have to work hard to get me pregnant. We'll need it then!"
Liu Xiaoqian had a "you don't understand" look on her face, her sense of superiority overflowing. Seeing Cheng Ming's disheartened
expression, the smug Liu Xiaoqian also humanely comforted him, "Keep it up, I'm ovulating right now!"
Encouraged, Cheng Ming roused himself and launched a counterattack, leaving Liu Xiaoqian utterly defeated, screaming incessantly.
Liu Xiaoqian had no intention of letting Cheng Ming off so easily. Even if he'd completed all five positions and ten ejaculations inside her, so
what? After all, there was more than one sex toy; the anus and mouth were also options. 　　 Thinking
this, Liu Xiaoqian couldn't help but hug Cheng Ming, who was relentlessly fucking her, a smug smile on her face…
