**********
... "Everyone has already learned about the phenomena of refraction and reflection, especially Snell's law for determining the angle of incidence and refraction within a medium. Today, we're going to specifically explain the refraction phenomenon of a convex lens." I recalled how Huang Ruoli 's big dick used his semen to wet the teacher's big breasts, and I still remember the content of Snell's law. Ha, actually, we've already experimented with this ourselves. Through the drill in the bathroom of the overnight camping resort, I clearly know that an object beyond twice the focal length of a convex lens will form a reduced, inverted, real image, while within one to two times the focal length, it will form a magnified, inverted, real image. Back then, we used this property to project the image of Instructor Shiting taking a shower onto the bathroom wall, not knowing how many offspring Tang Chenwei, Huang Ruoli, and I lost. The teacher began explaining the refraction of an object at various positions in front of a convex lens. After drawing the diagram on the electronic whiteboard, she even took out her phone and pretended to take a selfie, saying, "Just like girls hold their phones far away when taking selfies, so that a smaller image will appear on the film of a traditional camera or the sensor of a digital camera. Otherwise, how can such a big face fit in?" She used this to emphasize that the image formed beyond twice the focal length of a convex lens is smaller. However, the teacher's face is clearly very small, yet she used self-deprecation to deepen our impression. She should have changed it to taking a selfie of her chest instead. "A microscope can magnify a specimen using two convex lenses because the specimen, when imaged by the objective lens, is located between one and two times the focal length, already forming an inverted, magnified real image. This real image , located within the focal length of the eyepiece, is further magnified by the eyepiece, becoming an upright, magnified virtual image. However, compared to the original specimen, it is an inverted magnified virtual image, which is why it can be magnified up to 2000 times, though it inevitably becomes an inverted image." The teacher then explained the principles of various optical instruments. However, by this time, the students were almost swaying from not understanding, so Teacher Li Zhenzhen quickly distributed the convex lenses , giving each student two. "Please use the convex lenses to observe the following lesson content. Not using the convex lenses is a foul, and those who foul will need extra tutoring on Saturday ! Those who fail the quiz later will also need extra tutoring!" Hearing the most hated extra tutoring, the students all began adjusting the distance between themselves and the teacher using their convex lenses, trying to find the appropriate distance so they would know how far away they needed to be to see the lesson content clearly. What's even more terrifying is that the convex lenses the teacher gave each of us were of different specifications. The mirror surfaces varied in size and thickness, and consequently, the focal lengths also varied. We had to get up from our seats and move around to test them to find out the approximate focal length and suitable viewing distance. Using only one convex lens, we could only see an inverted image. Actually, just listening to the teacher's explanation was enough for me to understand about 70-80 the lesson, so seeing only an inverted image wasn't a big deal. I was confident I wouldn't do too badly on the quiz. However, once I saw the image through the convex lens, I had to quickly test the focal lengths of the two lenses in my hand to see the most complete lesson content! It turned out that the teacher was now loosening his shirt. The obvious black and white contrast in his initial attire was probably meant to make us aware of the characteristics of inverted images. Sure enough, even though I was seeing an inverted image through the convex lens, I could clearly see the teacher taking off his white shirt. But how could I be content with just seeing an upside-down image? I quickly gripped the convex lens with both hands, adjusting the distance back and forth until the teacher's beautiful figure was fully visible. Just as I found the right distance, the teacher had just stripped down to her underwear. At this point, Huang Ruoli couldn't resist the temptation. Clumsily trying to find the right distance, and unwilling to miss the teacher's striptease, he secretly began to admire her body with his naked eye. "Huang Ruoli cheated!" The teacher immediately noticed Huang Ruoli's cheating. Caught red-handed, Huang Ruoli was so frightened that he smashed the convex lens in his hand into pieces, leaving only the plastic frame around the lens intact, making a piercing sound. "When you see the teacher through a convex lens, the teacher can also see your eyes through the same lens. You see the teacher 's body as magnified, but the teacher sees your eyes as shrunken. This is called the reversibility of light. That's why the teacher can easily catch you cheating, because other students' eyes are magnified or shrunken, but your eyes remain the same size, which is very obvious. An object placed outside twice the focal length of a convex lens forms an inverted, shrunken real image, which is formed between one and two times the focal length on the opposite side of the lens. Conversely, if the object is placed between one and two times the focal length, the image is formed outside twice the focal length on the opposite side of the lens, resulting in an inverted, magnified real image. This is also the reversibility of light. For example, the sun is almost at infinity relative to the earth These parallel rays of light, after passing through a lens, will converge at the focal point of the convex lens to form a single point; but if the light source is placed at the focal point of the convex lens, it can become parallel rays that travel to infinity." The teacher, wearing only underwear, walked back and forth in front of Huang Ruoli, who was now only wearing one lens, allowing him to observe the teacher's figure through the mirror . Sure enough, the image was sometimes magnified and sometimes shrunken, but it was always an inverted image. The teacher's aesthetic sense was a bit off; her underwear didn't match her bra. The bra was mostly purple, while her underwear was a thin layer of yellow thong, clearly showing the shape of her crotch area. Later, I learned that purple and yellow are complementary colors in pigments, like her white shirt and black pencil skirt. The teacher deliberately used two contrasting colors to make the inverted image easier to observe. Through the convex lens, the teacher's F-cup breasts could appear even larger, and I couldn't help but laugh at the comical image reflected in the lens. Then, the teacher immediately handed out a quiz. Tang Chenwei and I had conducted a practical experiment with Instructor Shiting in the bathroom.

Both of them got full marks, and Li Fa also got full marks, but she wouldn't compete with me for the chance to take the Sabis exam, so I
didn't care.

"Huang Ruoli, is it that hard to understand? Another 0 points!" Although the teacher was dressed scantily, especially her underwear,
the pubic hair and camel hoof shape were so clear that it was almost like she wasn't wearing anything underneath, but she didn't seem to mind and walked closer to Huang Ruoli,
not afraid of being fantasized about by him again. The moment she put the exam paper on his desk, her huge breasts were only inches away from his.

"I just broke a lens, and I barely heard the lesson..." Huang Ruoli lowered his head sadly, but I,
sitting next to him, could easily see that his crotch was bulging high. Have you ever seen someone cry while getting an erection?
Huang Ruoli was obviously acting!

"But I'll learn it soon. I've got the method, I just need to practice!" Huang Ruoli looked
like an earnest young man, and even I was almost fooled by him!

"Tell me how to practice?" The teacher gently placed her hands on Huang Ruoli's desk, her large breasts
squeezed against her arms, creating a magnificent display of cleavage.

"Hehe, I'm shy." Huang Ruoli lowered her head and scratched her head, pretending to be a simple-minded child, oblivious to
the world's ways.

"It's okay, teacher will help you practice. It's more important that you quickly learn how to form an image using a convex lens." Teacher Li Zhenzhen
seemed to have an outpouring of maternal love, offering herself up step by step.

"Teacher, don't you think that forming an image using a convex lens is a lot like the relationship between men and women? When the light source is at infinity,
the image is formed at the focal point, just like when you walk into the classroom, everyone's eyes are on you."
Huang Ruoli was even better at talking nonsense than Chen Xing, the Chinese teacher in the third-year junior high school review class, leaving Teacher Li Zhenzhen stunned,
and a smile bloomed on her face because of Huang Ruoli's roundabout praise.

I haven't officially taken Mr. Chen Xing's class in my third year of junior high yet, but I've heard from older students that he's very
good at charming . I hope Ms. Li Zhenzhen doesn't get too close to him.

"Teacher, please lie down." Under Huang Ruoli's guidance, the teacher lay down on the other desk, like a specimen on
an dissection table, ready to be dissected. Huh? Wasn't Sha Bisi supposed to get the highest score? How come it's the mentally challenged student with a zero score
enjoying the teacher's personal guidance!

Huang Ruoli gestured towards the teacher's crotch: "If we consider this part of your penis as a mirror, and
mark , the base as the object's position, and the tip as the image's location, then
when your penis is pulled out, leaving only the head inside, it's as if the object is farther from the mirror, but the image is closer to the mirror. In other words,
the object is at twice the focal length, while the image is between one and two times the focal length. Also,
the part is larger, and it becomes smaller when squeezed inside, which matches the actual phenomenon of image formation!"

Although Huang Ruoli didn't actually pull down his pants to expose his penis, just this gesture made me tremble with fear. His penis, the size of
a black man's , was so large that if it were actually inserted into Teacher Li Zhenzhen's vagina, "once you go
black, you ever go black." Perhaps no one else's penis could
satisfy Teacher Li Zhenzhen anymore.

However, he didn't expose his penis, and the teacher didn't take off her underwear, so it seems I was just worrying unnecessarily.

"And when the penis is inserted deeper into the teacher's body, that is, when the object is closer to the mirror,
the image will be farther away from the mirror. And because the glans is closer to the very end, there's a little
space for baby development inside, right? The penis will actually be easier and become bigger!" Damn it, that's called
the uterus . Huang Ruoli pretended to be mentally challenged and knew how to go all out, even pretending not to know about the uterus.

Then Huang Ruoli actually lifted the teacher's legs and pressed his crotch against the teacher's thin silk panties. The bulging
crotch rubbed against the teacher's panties, simulating the action of intercourse, and it was already on the verge of getting
out of control !

The teacher felt her vulva being touched through her panties and quickly looked up at her genitals like a startled bird.

"Hmm, very good. If this helps you understand, then it's not a bad method!" The teacher was
a little surprised to find that Huang Ruoli was just scratching the surface and didn't actually rub his huge penis against her crotch.
She breathed a sigh of relief and quickly stood up.

"So, Huang Ruoli, have you learned it?" Teacher Li Zhenzhen tugged at her underwear. After being rubbed a couple of times,
her underwear had been pulled up a few times towards her upper body, making the camel hoof shape more obvious. The crotch of her underwear
almost directly revealed the shape of her labia minora. The teacher quickly adjusted the position of her underwear, otherwise everyone would be unable to listen to the lesson
later , as they would all be admiring the teacher's petals.

"I'll practice a few more times at home and I'll get it." Huang Ruoli turned around triumphantly to return to his seat, completely
unlike his usual self.

"Okay." Teacher Li Zhenzhen watched Huang Ruoli walk back to his seat with a sigh of relief, but then immediately
asked as if she remembered something, "How will you practice at home?"

"Practice with my sister!" Huang Ruoli answered casually.

You're talking nonsense, wake up, you don't even have a sister!

"No, no, no! You can't practice this with your sister!" The teacher grabbed Huang Ruoli's arm nervously.

At this moment, Teacher Li Zhenzhen's attention was entirely focused on Huang Ruoli, and she didn't notice that Tang Chenwei and Chen Yuhao
were internally injured from holding back their laughter.

"Teacher will practice with you. You'll learn it in class today, but you can't practice with your sister at home!" To prevent Huang Ruoli from having incestuous relations with his non-existent sister,
the teacher quickly took advantage of Huang Ruoli's current enthusiasm to
teach him lens imaging.

So the teacher took off Huang Ruoli's pants and used a whiteboard marker to draw
the position aligning with the mirror surface in the middle of Huang Ruoli's penis. Then, she drew the focal length position and the position twice the focal length position forward, and symmetrically drew
the focal length position and the position twice the focal length position backward as well. Then she had Huang Ruoli practice with her body.

If Huang Ruoli's penis hadn't been so long, it wouldn't have been possible to mark a total of five points on it.

"Everyone, please note that a lens has only one focal length, but two focal points. So,
the middle of serves as the reference point aligning with the mirror surface. There is a focal point both forward and backward, and
the distance between these two points and the reference point is the same. There is also a position twice the focal length position on each of them." After the teacher finished speaking, she spread her legs and sat on the table,
indicating that Huang Ruoli, with his penis simulating the distance of an object, should stand between the teacher's legs.

The teacher's legs were spread wide; although she hadn't taken off her underwear, the petals of her vulva were clearly visible. She
lay on the table while Huang Ruoli held his penis and gestured towards her stomach.

Wait, this scene looks so familiar... Isn't this the time I lost my virginity and ejaculated inside the teacher? I used his penis as a marker...
Measuring the depth of the teacher's vagina with a ruler? It turns out that males unconsciously tend to think alike when trying to seduce someone!

"If your penis is now inside the teacher, reaching the midpoint, which can be considered as the object
at twice the focal length, where would the image be?" From my perspective, Huang Ruoli's penis is on the teacher's
lower abdomen, the middle of his penis aligning perfectly with the entrance to her vagina. If we consider the distance from the teacher's vagina to the base of Huang Ruoli's penis as
twice the focal length, then the distance from the middle of Huang Ruoli's penis to the tip of the glans is also twice the focal length.

"The image is also at twice the focal length." Huang Ruoli is a typical middle school boy who gets an erection easily.
Looking at his large penis on the teacher's mons pubis, even though the teacher hasn't let him in, just imagining
his penis penetrating the teacher's tight opening through this misaligned fantasy already makes his penis swell to a purple hue, and his shaft
tremble .

"What if we move forward a little, shortening the object's position to between one and two focal lengths?" The teacher instructed
Huang Ruoli to move his body forward, bringing his lower abdomen closer to the teacher's vaginal opening, while the tip of
his penis would penetrate deeper into the teacher's body, approaching her uterus—if Huang Ruoli's penis
actually entered the teacher's body. At this point, it was merely a description of relative position.

Clearly, Huang Ruoli was now simulating the portion of his penis remaining inside the teacher's body exceeding twice the focal
length . Even someone as intellectually challenged as Huang Ruoli understood the teacher's explanation and replied, "If the object is
between one and two focal lengths from the mirror, the image will be outside twice the focal length and appear larger!"

"What if the object is more than twice the focal length?" As the teacher asked the question, Huang Ruoli automatically pulled his lower abdomen back, bringing the tip
of his penis closer and closer to the teacher's vaginal opening. He immediately replied, "If the object is more than twice the focal length, the image will be
between one and two times the focal length. Will it be magnified or reduced...?" The position was easy to observe, but the magnification or reduction was
not immediately clear. So, Teacher Li Zhenzhen closed her legs and squeezed Huang Ruoli's penis with her thighs.
Huang Ruoli understood and loudly replied, "Reduced!"

Next, Huang Ruoli intentionally pressed his penis against the teacher's mons pubis, experimenting back and forth. Whenever he
thrust his penis into the teacher's simulated body, the teacher would open her legs to make him remember that the image was magnified,
which also made it easier for his glans to reach the uterus. When he pulled his penis away, the teacher would close her legs
or even squeeze Huang Ruoli's penis to make him remember that the image would be reduced when the object was more than twice the focal length.

Fortunately, their pants weren't off yet. Otherwise, if the teacher had willingly spread her legs to meet Huang Ruoli's thrust, and
he had actually inserted his penis into her vagina, it would have been like hitting her lungs!

Only now did I see Huang Ruoli's intention clearly. He didn't make any special pressing motion with his penis when moving forward,
but when moving backward, he deliberately pressed his penis down with his palm, making it tightly contact the teacher's underwear. This caused
the teacher's underwear to loosen further and further, and the pubic hair at the upper edge of her triangle area was even peeking out from the waistband!

Because he didn't make any special movements when moving forward, the teacher didn't pay attention to his actions. After all, such a dangerous situation hadn't happened if nothing went wrong
when moving forward , so how could the problem be with the penis moving backward?

Just as I saw that the waistband of the teacher's underwear was almost slipping off her hip bone, Huang Ruoli suddenly asked,
"Teacher, I understand the image position and size of a convex lens, but the textbook often asks us to answer whether
it's a real image or a virtual image. What are real and virtual images?"

"A real image is formed by actual light rays, while a virtual image is the opposite." The teacher made Huang Ruoli follow the instructions
back and forth , completely unaware that her underwear, except for the part pressed against her buttocks, had been made extremely loose,
and her genitals could be seen directly from the crotch! Moreover, after such a long period of simulated
intercourse , and with Huang Ruoli rubbing against the teacher's vulva to some extent, the teacher's area was inevitably wet.
In addition to the two petals being slightly engorged and open, the center of the crotch of her underwear was also wet due to physiological reactions!

"Then were the images formed by those convex lenses real or virtual?" Huang Ruoli still tried her
best to make the teacher's underwear even looser, but she still pretended to be eager to learn and asked, acting very innocent,
as if there was a defect in her chromosomes.

"Except for the upright, magnified virtual image within the focal length, everything else is a real image." The teacher felt
Huang Ruoli 's penis moving away from her lower abdomen and towards her vaginal opening. She was probably practicing the reduced
, inverted real image from twice the focal length. So, she skillfully brought her legs together again, wanting Huang Ruoli to feel his penis being squeezed and shrunken.

This time, instead of opening her legs as Huang Ruoli moved forward, she automatically opened them because
she was used to the motion of opening and closing her legs. Even though Huang Ruoli's penis wasn't moving forward,
the teacher's legs opened automatically. The gap in her panties was so large that not only could her genitals be seen, but
Huang Ruoli's thick penis could easily penetrate her crotch and directly into her vagina!

Just as I was thinking about this, Huang Ruoli, with lightning speed, parted
the teacher's , grasped his penis with the other, and thrust it between her labia. He also thrust his hips forward forcefully,
and with the teacher's legs spread wide, the glans must have reached the deepest part of her vagina in one go!

"Ruoli, what are you doing!" Caught off guard by the sudden intrusion, Teacher Li Zhenzhen scrambled to
her feet in a panic. However, because she had her legs spread wide, not only was she immediately penetrated to the bottom by her student, but Huang Ruoli's
weight also pressed down on her, making it impossible for her to move beyond her neck and lower body.

"Didn't you just say that convex lenses produce real images unless the object is within their focal length? Real
images are formed by actual light rays, so I was wrong just now. You should let the actual light rays enter the mirror to form an image; that's what
makes a real image." Huang Ruoli indeed let his enormous, incredibly real member penetrate the teacher's "mirror,"
creating a magnified image at twice the focal length, near her uterus!

"That's not what I meant, teacher! Pull it out!" Teacher Li Zhenzhen struggled, shaking her long hair.
Huang Ruoli obediently withdrew his penis a little.

Just as I breathed a sigh of relief, thankful that the teacher had only been penetrated once and the farce was about to end, Huang Ruoli
suddenly thrust his buttocks forward again! In other words, he hadn't even pulled his penis out of the teacher's body before
thrusting it forward again. Accompanied by the teacher's high-frequency muffled groans, Huang Ruoli preemptively asked, "Is the position
wrong? This should be right, right?"

The teacher shook her head violently, whether out of anger, anxiety, or fear of being fucked senseless by Huang Ruoli's big dick, it was hard to tell.
She quickly pushed Huang Ruoli's upper body away with both hands, her face flushed, and said, "No, just pull it out!"

"Is that wrong again?" Huang Ruoli was thrusting violently with his lower body, but his face pretended that he had made a mistake in the "experiment"
and was adjusting his position. Before the teacher could speak, he recited to himself, "Beyond twice the focal length,
a reduced inverted real image; between the focal length and twice the focal length, a magnified inverted real image... That's right." But his crotch continued to thrust in and out of the teacher's tender hole without any
politeness , deliberately misunderstanding the teacher's meaning, and showing no
intention of stopping.

"No, no!" The teacher bit her lower lip, sometimes resisting, sometimes unable to cope, and could only endure
Huang Ruoli's penis ramming inside her, while constantly letting out muffled groans of "uh, uh."

"Huh? That beyond twice the focal length is a magnified inverted real image?" Huang Ruoli pulled his penis out a little and
stopped thrusting suspiciously.

"No, it's shrinking." The teacher, probably afraid that Huang Ruoli's hard work would be wasted again,
actually closed her legs to squeeze Huang Ruoli's bare buttocks.

"I knew it!" Huang Ruoli then thrust his buttocks forward again: "Between one and two focal lengths?"
he asked smugly.

"Magnification!" This time, the teacher didn't resist, but instead spread her legs wide, allowing Huang Ruoli to perceive
the object as being between one and two focal lengths, with the image appearing outside of that focal length; that is, the closer Huang Ruoli's lower abdomen was to the teacher's
vaginal opening, the farther the glans penis would be from the vaginal opening. At this point, the glans penis, freed from the vaginal pressure,
penetrated deeper into the uterus, thus appearing larger!

These few times, it became as if the teacher was actively encouraging Huang Ruoli to make thrusting motions. Looking through
Huang Ruoli's crotch at the teacher's wide-open vagina, and the color of the area where Huang Ruoli was joined changing from pink to
red, I felt my heart was breaking, especially as the teacher's resistance grew increasingly indistinct, leaving only
panting "ha...ha..."

The only consolation was that, because they kept discussing the two-times focal length and the range between one and two times the focal length,
Huang Ruoli actually controlled the range of his thrusts, not going all the way in, at least not damaging the teacher's vagina.
However, because of this, the teacher was less vigilant, thinking that this student was just eager to learn, allowing his
enormous penis to go in and out of her body.

No, they've already been thrusting for several rounds, and based on past experience, Huang Ruoli's premature ejaculation
is well-known. We absolutely cannot let Huang Ruoli ejaculate inside the teacher. His glans is so deep; if he ejaculates, it will definitely
go directly into the teacher's uterus. Those billions of sperm will have a high chance of swimming to the front of the fallopian tubes and causing the teacher to conceive!

"Teacher, what does that object look like at infinity?" Li Fa asked, as if reading my mind.

"It only appears as a point at the focal point," the teacher replied, frowning as she endured the fullness Huang Ruoli brought to her vagina
, but it was almost impossible to hear what she was saying.

"Can I try to experience it?" Li Fa said, walking up to Teacher Li Zhenzhen. Even
Huang Ruoli, who was quite dim-witted, knew that Li Fa was there to cause trouble. Taking advantage of the teacher's low alertness, he quickly
recited the imaging results aloud: "Beyond twice the focal length, a reduced, inverted real image; between the focal length and twice the focal length, a magnified, inverted real
image," while increasing the speed of his thrusts. He wanted to be the first to reach orgasm using the teacher's body and experience the unprecedented
pleasure of ejaculation inside her!

"Teacher, I want to know, if, the object, is within the focal length, what image does it form..." Huang Ruoli
was already out of breath, his words fragmented. But based on their previous assumption, the object
being within the focal length meant being inserted to the very bottom. Considering Huang Ruoli's current behavior, he wanted to bury his glans deep inside the teacher's
uterus and ejaculate, otherwise he wouldn't have suddenly mentioned "within the focal length"!

"Within the focal length, an upright, magnified virtual image..." The teacher had her eyes closed, completely unaware that with this one thrust,
Huang Ruoli would insert his penis to the deepest point!

"Illusion, illusion, I need to pee..." Just as Li Fa walked to Huang Ruoli's side, Huang Ruoli had already
wrapped his arms around the teacher's waist, squinted his eyes, and pushed his buttocks all the way down, with only his scrotum still outside the teacher's body; the rest
was completely submerged in the teacher's warm, moist depths!

Pee? Men don't urinate during intercourse; he's about to ejaculate!

In the instant my expression changed drastically, Li Fa poked Huang Ruoli's left and right ribs with both hands. Taking advantage of Huang Ruoli's
pain and distraction, Li Fa dragged Huang Ruoli's body backward. Even though he was tightly wrapped around Teacher Li Zhenzhen's
waist , not wanting to let this rare ejaculation opportunity slip away, the heroine Li Fa still successfully
freed her 20-centimeter-long penis from the teacher's vaginal confinement.

The moment Huang Ruoli's glans left the teacher's vaginal opening, I noticed that Huang Ruoli's urethral opening was already ejaculating.
I just didn't know if it was ejaculating after leaving the teacher's vagina or if it had already ejaculated halfway into the uterus and was interrupted.

Although Li Fa was dragging Huang Ruoli towards the so-called infinity, Huang Ruoli still held onto
Teacher Li Zhenzhen's slender waist with his left hand and adjusted the angle of his penis with his right. Although it was impossible to ejaculate inside the teacher,
he still managed to spray most of his semen onto the center of the teacher's labia minora, from the pubic hair all the way to the entrance of the vagina, everywhere was covered
with his thick, smelly, white, cloudy semen.

"Wow, as expected, when an object is at infinity, the image only appears as a point at the focal length!" Li Fa
pointed to the semen on the teacher's pubic hair with feigned innocence, which was roughly near the focal point they had just defined.

Huang Ruoli's expression was ambiguous, he probably didn't expect that our Li Fa could play the fool so well, just like him,
both were acting skills of Pi Meixi Enpan!

Looking at the teacher's vulva covered with Huang Ruoli's semen, I felt heartbroken but also relieved, at least the teacher
wasn't internally ejaculated into. I have to thank Li Fa for saving me again, but when she turned to look at me, her guilty
expression made me feel like something terrible was about to happen.

Now I finally understand why Huang Ruoli had that ambiguous smile. He was unhappy that his ejaculation was interrupted, but
happy that he finally got to experience Teacher Li Zhenzhen's pleasure. Following Chen Yuhao, Tang Chenwei, and Cheng Yixin, I became
the fifth student to enter Teacher Li's body.

And the white, semi-transparent liquid slowly flowing from Teacher Li Zhenzhen's vaginal opening indicated that
Huang Ruoli had already ejaculated a considerable amount of semen inside her before Li Fa intervened…

I was astonished that Teacher Li had still been penetrated by Huang Ruoli. Teacher Li Zhenzhen, however, composed herself,
glanced at me, and put her underwear back in place. The crotch, gradually soaked with semen flowing from her vagina, appeared
unusually transparent, even clearly showing her labia minora, which were still slightly open after intercourse. Teacher Li quickly took…
She stuffed the tissue into her underwear, then nonchalantly put on her shirt and skirt and continued teaching. No one
would know that Huang Ruoli had just achieved the feat of ejaculating inside the teacher.

"Classmates," she said, "Huang Ruoli ejaculated at an infinite distance from the mirror, ultimately forming only
a point near the focal point. This is based on the principle of a magnifying glass converging sunlight to start a fire. To make a fire rise quickly, the combustible
material must be placed at the focal point of a convex lens, so the light converges to a single point, just like Huang Ruoli only
ejaculated near the teacher's pubic hair, forming a small area." Despite being covered in semen, the teacher deliberately said only
a small amount , seemingly desperately trying to conceal the fact that she had been ejaculated inside by a student again. Well, if every male student thought
they could just casually penetrate the teacher and ejaculate inside her, how would she teach in the future? It's better to be careful about the boundaries.

"There's an episode of Doraemon where Nobita gets captured by a dinosaur, and he uses his glasses to focus sunlight and burn
the dinosaur's fingers to escape. That's completely wrong. Nobita's glasses are concave lenses;
they don't focus light." The teacher went on and on, citing
examples . Most students were focused on the lecture, but I knew this was just the teacher trying to distract them
.

If only the scene I just witnessed was real, I thought, pondering the difference between real and virtual images. Real images
can be projected; they are actual images, like Huang Ruoli's penis clearly entering the teacher
's vagina. The scene was shocking, but before ejaculation, it didn't seem like a big deal. Virtual images can only
be observed . Besides Huang Ruoli and the teacher, only I saw Huang Ruoli ejaculate inside the teacher.
If it weren't projected, who would know? Would Yui Hatano's future husband stop loving her just because she was ejaculated into hundreds of times in an AV
? Maybe AVs are all fake ejaculation! I convinced myself that perhaps what I just saw was
just an illusion, and that I still love actress Li Zhenzhen just the same
