Junior High School Physics and Chemistry Class (Part 3)

Word count: 5314.
After the experiment, we returned to the classroom for another quiz, this time on measurement and density calculations.
Although I still got the highest score, I missed one question and only got 90.
This time, the class scores improved significantly; three students passed: Tang Chenwei, Chen Yuhao, and Huang Ruoli, three gifted students who usually get 100 even with their feet. They all scored just 60, barely passing.
Tsk, are these guys' scores directly proportional to their enjoyment in class? The more they enjoy it, the higher their scores? My deduction must be correct, because the following week in physics and chemistry class, the pre-class quiz brought their scores down to a level where even Aaron Yan or Nobita could compete.
"Which of the following statements about measurement is correct? (a) When measuring height, looking down may overestimate height. (b) The more decimal places an estimate is taken during measurement, the more accurate it will be. (c) When measuring salt, the displacement method can be used directly to measure the volume. (d) The average value after measurement should be rounded to the same number of decimal places as the original data." How could you get this question wrong?
Teacher Li Hua was still dressed in the same revealing outfit as in the previous class. She wore a sheer blouse over a deep V-neck thin-strapped top, and only denim shorts that almost reached her crotch.
"Teacher, why can't you overestimate height when measuring from top to bottom? If you hold the height measuring tape upside down, it will overestimate, right?"
Chen Yuhao shrugged, looking like he wasn't wrong.
"Why did you deliberately hold the height measuring scale upside down?"
Teacher Li Hua was so agitated that her collarbone turned red, and she questioned these gifted students with trembling hands, asking why they would ask such a stupid question.
"The mass of the object to be measured on an equal-arm balance is the reading of the weights plus the reading of the weights on the side of the balance; why do some questions say
that if the weights and the object on the equal-arm balance are placed on the wrong side, the reading must be the weight reading minus the weight reading to get the correct reading? Just don't put them upside down, right?"
Chen Yuhao asked suspiciously, tilting his head.
"..."
Indeed, there were such pointless questions. Teacher Li Hua was so angry that she was speechless and could only accept these people's wildly imaginative answers and miserable scores.
"This is my observation, don't criticize me, unless you are a physics major."
Chen Yuhao deliberately imitated the tone of geologist Aaron Yan. Teacher Li Hua's shoulders trembled with anger as she walked back to the podium.
"I am a physics major at National Taiwan Normal University!"
the teacher turned around and replied.
"Then we should ask your seniors and professors to set fewer questions that are unclear or illogical,"
Chen Yuhao said expressionlessly.
Sigh, that's true. Since they're even using a pointless question about misusing a balance scale as a question, how can they blame the students for answering other questions with wildly imaginative assumptions?
The teacher knew this was the education system's fault as a whole, so she had to swallow her anger and continue with today's lesson.
But just then, a soft singing voice filled the classroom: "Education is the foundation of the nation~~~ Teacher training is especially revered~~~ Diligent in my studies, advancing in my virtue, strengthening my body."
Tang Chenwei and Huang Ruoli were actually singing a song from who-knows-where, the melody catchy and quite pleasant.
"Don't sing our National Taiwan Normal University's school song!"
The teacher, shocked, turned around angrily to protest.
Ha, it seems Tang Chenwei must have secretly accessed the teacher's basic information; otherwise, how could he have prepared the National Taiwan Normal University's school song beforehand to tease the teacher? Not to mention, he and Huang Ruoli were putting on a seamless act.
Later, I learned from other classmates that the teacher's real name was Li Zhenzhen, which sounded really cute and perfectly matched the naive and inexperienced feeling she had when she first started teaching.
Of course, Tang Chenwei learned all this information by abusing his supreme power in the tutoring center.
"Calculating concentration and solubility has always been a weak point for junior high school students when they first learn physics and chemistry. Concentration is usually calculated as a weight percentage, with the total weight of the solution as the denominator and the total weight of the solute as the numerator, to calculate
the percentage content of the solute. Solubility, on the other hand,
is described as the mass of solute that can dissolve in 100 grams of solvent at a fixed temperature."
The teacher quickly wrote down the formulas, while the nearly thirty students below seemed uninterested.
The teacher knew that no one would pay attention to her if she taught in the usual way, so in order to keep her job, she had to change her approach: "Suppose that in a certain Muslim country, one man can marry four wives, and all men and women in the country are already married. In terms of weight percentage, the percentage of men in that country is one-fifth, or 20%. But in terms of solubility, it is 25 men for every 100 women."
"Teacher, you should have explained it like this a long time ago!"
Tang Chenwei clapped his hands and happily pointed at Teacher Li Zhenzhen.
Indeed, with the teacher's examples, we instantly understood the similarities and differences between weight percentage and solubility. Presented numerically as 20 and 25, they were clearly completely different concepts.
"When a solute dissolves, it diffuses to every part of the solution. We can determine the concentration of the solution by its color or various properties, such as whether a sugar solution is sweet or a salt solution is salty."
The teacher wrote on the electronic whiteboard, her side breast faintly visible through the thin gauze, reminding us of her almost naked appearance last week.
"Teacher, what is diffusion?"
Zhen Shuzhu raised her hand and asked.
"It's the network-like movement of molecules from high-concentration areas to low-concentration areas through random motion."
"Can you see it?"
Zhen Shuzhu pressed.
"Sure, we can go to the lab building and get ferric sulfate or other colored chemicals for our experiment."
"Teacher, I'm busy. Do you know how much trouble it would cause the tutoring center if we had to bring a group from here without an appointment? It's not like we're the only ones in science class. Besides, the movement of chemicals is invisible under a regular optical microscope."
Tang Chenwei started teasing the pitiful-looking teacher, Li Zhenzhen, again.
"But Zhen Shuzhu wants to know the principle of diffusion."
"Teacher, I suggest we use a substance visible under a regular optical microscope for our experiment. We have it in the classroom, and it's probably visible to the naked eye. It should move randomly in water, which will definitely help everyone understand the mysteries of diffusion."
Tang Chenwei pursed his lips, seemingly after careful consideration.
"What is it?"
the teacher asked anxiously. If there were such easily obtainable experimental reagents, and she was completely unaware of them, and they still needed to go to the lab building, this was a huge challenge.
"Semen,"
Tang Chenwei said seriously.
The teacher suppressed his anger, finding it difficult to lash out. After all, with the economy in such a terrible state, where could he find a job that cost over 50,000 a month? While our cram school owner exploited administrative staff to a considerable extent, he was quite generous with hourly wages for the professional teachers.
"So tell me, where are you going to get the semen?"
the teacher feigned composure, though beads of sweat began to appear on his forehead.
"All of us male students have some,"
Tang Chenwei replied, feigning ignorance. In reality, he wanted the teacher to provide him with services, but he deliberately didn't say it outright, subtly guiding the teacher to reveal and fulfill his desired outcome.
"Then who among you is willing to provide semen?"
The teacher, succumbing to practical considerations, finally uttered what the gifted students wanted to hear.
"I can sponsor semen by masturbating, but I'm afraid I'll finish before school's over,"
Tang Chenwei sneered, taking the opportunity to boast about his stamina, implying he might even want the teacher to help him.
"I can help my classmate extract the semen, but to avoid delaying the class, can I choose the classmate who can ejaculate the fastest?"
the teacher asked.
"Whatever you want."
Now it seems that Tang Chenwei doesn't really need to get the teacher. He's letting the beautiful, busty teacher choose her service target. Maybe he just wants to mess with her.
If I were Teacher Li Zhenzhen, I would probably choose Tang Chenwei directly. After all, he's the boss's son. Maybe if I serve him well, he won't team up with those gifted students to cause trouble anymore.
"Then I choose Xiaoping."
After saying that, the teacher gently placed her hand on my desk, which startled me, especially since I've never used "Xiaoping" as my name.
Wait, wait, what does this mean? To extract semen for a diffusion experiment, the teacher chose me, but I don't know how to masturbate!? "Teacher, I don't know how to masturbate."
I don't know how to masturbate, but I'm not so stupid that I don't even know how to extract semen. In this situation, to avoid delaying the class, I'd better make things clear first.
"Hahaha!"
Laughter erupted in the classroom. The precocious gifted students seemed to find my inability to masturbate amusing, laughing uncontrollably.
"Teacher, I'm fast too! You're definitely not losing out by helping me extract the semen,"
Tang Chenwei softened his stance a bit, willingly admitting to premature ejaculation in hopes of receiving the teacher's assistance.
"Okay, I'll extract your semen first, but to make it easier to calculate the concentration later, I'll also extract semen for Xiaoping or other students. If you last longer than Xiaoping or the other students, it means you're lying and have no sincerity whatsoever. From now on, please don't speak during class, okay?"
the teacher asked sternly.
Actually, she already knew what these people were thinking, but for the sake of her job and to maintain her remaining dignity, she still hoped not to let them take advantage of her.
So when they finally gave themselves away and tried to take advantage of the teacher, she did her best to prevent them from indulging their lust.
As for me, after consistently ranking last in the midterms, I was already lucky to be able to continue attending classes at Bedford. How could I dare to disobey Tang Chenwei and the others? If I were kicked out of Bedford, there would definitely be a family revolution at home.
After deciding that my semen would be extracted, Teacher Li Zhenzhen made a phone call, and a student worker brought in two beakers from outside the door. One beaker was empty, and the other contained saline solution. Then the classroom door closed again.
What happened inside, no one except us knew.
The teacher's eyes betrayed her unease, but further hesitation only gave her more ammunition. These second-year junior high students before her were no less wicked than the 11-year-old girl surnamed Xie who participated in the Zhudong girl's murder. Moreover, they knew far more than that 11-year-old girl, and their intelligence was undoubtedly far superior to hers. If she didn't want to lose her job, she had to act decisively.
So she made me stand on the platform, then squatted down in front of me, pulled down my pants, revealing my limp penis, pale in comparison to Huang Ruoli's.
My face instantly flushed red, and I dared not look at my genitals any longer. Looking down at the teacher's F-cup cleavage and her breasts almost overflowing from her bra, I was even more ashamed and didn't know where to look.
I thought the teacher was going to use visual stimulation to help me get an erection, and then teach me how to masturbate until I ejaculated. But unexpectedly, just as I turned my face away in shame, I felt a warm, moist sensation in my limp penis. I felt my penis was swollen and redder than my face.
I looked down and could only see the teacher's face from above, not my penis. Combined with the strange feeling I'd just experienced, I involuntarily cried out, "Teacher, where's my penis? My penis is gone!"
Just as the whole class burst into laughter again, the teacher tilted her head back so I could see her features. Her features were still delicate and beautiful, and her eyes looked up at me pitifully like an abandoned dog. But her cheeks were deeply sunken, and I then noticed that she had something familiar stuffed in her mouth.
As she tilted her head back, the object became clearer and clearer, covered in the teacher's saliva and bulging veins. It wasn't until the entire glans was almost out of the teacher's red lips that I realized it was my penis. So my penis hadn't disappeared; it was in the teacher's mouth! I thought the teacher would at most give me a handjob, but I never expected her to suddenly use her mouth to service me! My mind went blank; I could only foolishly enjoy the pleasurable sensation between my legs, perhaps amplified by the teacher's cleavage and her alluringly serious expression.
That warmth, that tingling sensation, should have belonged to Tang Chenwei. Worried about potential retaliation for interfering, I quickly looked towards him and Chen Yuhao, only to see their mouths agape, seemingly unable to believe that Teacher Li Zhenzhen would actually give in.
Although Teacher Li Zhenzhen wasn't actually performing oral sex on them, she genuinely abandoned her teacherly reserve and was giving her student oral sex. They couldn't hide their excitement, completely absorbed in the moment, their eyes showing none of their usual cunning and mischievous nature, and for the time being, they didn't seem to harbor any resentment towards me.
Not long after the teacher began servicing me, a strange sensation arose in my groin. The tingling sensation wasn't just concentrated on the glans but spread throughout my body, even reaching the sides of my back, where my kidneys are located.
The reactions in these sensitive areas made me instinctively feel the urge to urinate, so I quickly groaned, "Teacher, I need to pee!"
Upon hearing this, the teacher immediately grasped the base of my penis with one hand, pulling it out of her mouth. Then, her tongue skillfully licked the opening of my urethra, commonly known as the meatus, while her hand continued to stroke back and forth.
Afraid of urinating in the teacher's mouth, I desperately twisted my lower body, trying to break free from her grasp on my penis, but she refused to release it.
In despair, I grabbed her F-cup breasts and squeezed them hard, hoping she would let me go and not make me urinate in front of the whole class.
However, the teacher completely ignored my assault on her breasts, only focusing more intently on teasing the meatus with her tongue.
I held back my urine by squeezing the teacher's breasts tightly, while simultaneously contracting my anus to keep my penis still. But after a few moments
, I had nowhere left to retreat. I could only squeeze the white, tender fatty tissue, which I couldn't grasp with one hand, while releasing my perineum, which was so taut it was almost broken, helplessly letting my desires run wild. Just as I thought I had finished urinating, Teacher Li Zhenzhen's tongue was touched by the fluid gushing from my urethra. She then grabbed a beaker with one hand and pressed my erect penis down at an unnatural angle with the other, continuing to rub it until I felt my glans twitching and my urethra began to spurt white fluid into the beaker.
Only then did I manage to achieve a semblance of balance between the pleasure in my penis and the rationality in my mind. According to what I had learned from porn, was this what ejaculation was?! Watching my urethra spurt out forcefully several times until about 3 to 5 milliliters of thick white fluid were distributed in the beaker, I finally realized that this was my first ejaculation.
Although most of them would perish in the upcoming experiments, at least several million sperm remained on Professor Li Zhenzhen's tongue, perhaps to be ingested and become part of her nutrients.
Thinking that my first ejaculation had occurred in such an unusual way with my teacher's body, I felt a sense of satisfaction in possessing her, yet also a touch of melancholy; after all, given this situation, the gifted student group would eventually possess her body, and might even go further.
Professor Li Zhenzhen licked her lips, making sure no bodily fluids ruined her makeup, before raising the beaker containing my semen, adding saline solution, and showing it to Zhen Shuzhu to demonstrate the spread of the semen. It truly did form spiderweb-like patterns—could this be the web-like spread the teacher had mentioned? Zhen Shuzhu glared at me. I thought she would just say she'd seen it, but I didn't expect her to be so inquisitive. After all, she's a gifted student, and for the sake of her image, she couldn't just ask Tang Chenwei and his gang for semen to experiment on just because they were close. Now that she had the chance to see semen with her own eyes, she wasn't disgusted by the fact that it came from me; instead, she observed intently.
"Semen is a thick, jelly-like liquid in the first five minutes after ejaculation. This is an evolutionary result to stay in the woman's body and increase the chances of conception. After a few more minutes, the semen becomes a true liquid, and that's when you can see the sperm swimming in all directions, causing the saline solution to become thicker and more cloudy."
Teacher Li Zhenzhen, while catching her breath to calm herself, also stared intently at my billions of offspring in the saline solution. [Recent rating record: wj522 gold coins +8. Thanks for sharing, the forum is more exciting with you!]
