What a coincidence? After Wang Sen returns, I need to find an opportunity to learn more about this man.
"Oh, right, son. Next week, you'll have to eat dinner by yourself for a few nights. I have to attend an adult health lecture organized by the Education Bureau with some colleagues from school," Mom said as she dried her hair.
"Huh? A lecture? What kind of lecture is this? Why are you going?"
"Your senior class is about to turn 18 and become adults, right? The Education Bureau has asked a few of us to organize a sex education lecture. I'm preparing the lesson plan these days. If there's anything you want to eat next week, just let me know. Order takeout, and I'll pay for it."
"Alright, give me a bit more money. I'm broke lately."
"Don't spend recklessly! Save some money, okay?!"
"Alright, alright, I got it. Stop nagging..."
Lying in bed, I thought about how to find a chance to approach Wang Sen. After much consideration, I decided that reaching out through Wang Mu would be the best way. I made up my mind to contact Wang Mu again next week.
The next day at school, the entire third floor was unusually quiet. Mom, Principal Yan, and a few other humanities teachers had been sent to the Education Bureau to assist with the lecture. The remaining science teachers handed out some test papers for the students to complete. After finishing, they were given the answer keys to check their work themselves, so the hallway was exceptionally peaceful.
"Students, after you finish the test papers, pause your work and tasks. We'll take an hour to watch a live-streamed sex education lecture," the vice principal's voice echoed through the classroom speakers.
"What's a sex education lecture?" "As long as I don't have to write more test papers, I'll do anything," chattered voices filled the classroom.
"Everyone, quiet down. Class monitor, turn on the big screen," Teacher Wu quickly restored order in the class and had the large teaching screen turned on. "This lecture is a sex education session specifically for this year's senior class. It's being live-streamed by the Education Bureau, and our district's lecture will be led by Teacher Sun Xiudong," the loudspeaker added.
"I am Sun Xiudong. It is my great honor to host this year's lecture on adult sexual awareness for the senior class in our district," Mom gracefully stepped onto the stage in the live stream and bowed. She was dressed very formally today: a white double-layered linen blouse with all three buttons at the collar fastened, paired with a knee-length, matte gray-black pencil skirt. The blouse was neatly tucked into the skirt, and the tight, body-hugging design showcased her figure perfectly. Below her knees, her legs were covered in what looked like thick flesh-colored stockings, and she wore 6cm deep brown patent leather high heels. Her long, beautiful hair was tied up and secured with a hairpin at the back. Overall, Mom looked extremely professional.
"Under the current education system, most students and parents treat the concept of 'sex' as taboo, fearing it like a tiger and viewing it as synonymous with filth and vulgarity. In the next hour, I will guide everyone through a detailed understanding of female anatomy and more common knowledge about 'sex'," Mom concluded her opening remarks on stage and proceeded to open her PowerPoint presentation.
A series of photos appeared on the large screen, so explicit that all of us students in the class blushed with embarrassment. The photos were artistic nude shots of a woman with her face pixelated. In the images, the woman was completely naked except for a pair of ballet shoes on her feet, captured in a continuous sequence of ballet movements, each frame recorded by the camera. The woman was about 170 cm tall, with a notably full bust. Because her figure closely resembled that of the woman in the photos, some students began to superimpose their own mothers' images onto the woman in the pictures.
"Students, what is the first thing that comes to your mind when you see these photos? Whatever you're thinking right now, I want you to view these photos from an artistic perspective. The first lesson I want to impart is this: a woman's body ≠ vulgar sexual concepts. We must look at this objectively!" Mom passionately declared during the lecture.
Ding. "This woman is Yan Yan," I received a message from Wang Mu, who was also watching the live-streamed lecture.
"How do you know?" I asked Wang Mu in reply.
"I'm very familiar with this woman's body," Wang Mu answered.
So, Mom had used Principal Yan's photos for her presentation slides. So this was the kind of support lecture it was.
"Next, we will cover two very important sections. Please pay close attention," Mom said as she swiped through the slides, stopping at the final few images. In the photos, the woman was sitting on the floor, her ballet-shoed feet spread straight into an M-shape. Thanks to her ballet training, the angle between her legs was perfectly straight, with her toes lightly touching the ground. Her arms reached through from the sides of her thighs, and her hands forcefully spread her vulva apart, one on each side. Mom zoomed in and enlarged the part where the woman was spreading herself open, then continued her explanation.
"This is the mons pubis, the raised fatty pad, covered with pubic hair distributed in an inverted triangle pattern."
"The clitoris, rich in nerve endings, highly sensitive to sexual stimulation."
"These are the labia majora, a pair of longitudinal skin folds on the inner sides of the thighs, prone to hematoma formation after trauma."
"These are the labia minora, a pair of thin skin folds located on the inner sides of the labia majora."
"The Bartholin's glands secrete mucus for lubrication during sexual arousal."
"You should be aware of the locations of the urethral and vaginal openings."
"The hymen is a thin mucosal fold surrounding the vaginal opening, usually with a central hole that can be round or crescent-shaped. The size of the opening varies greatly—some are so small they can't even accommodate a finger, while others can fit two fingers. Some women even lack a hymen altogether." Mom systematically explained the structure of the female external genitalia, emphasizing the hymen in particular and reminding the female students watching to pay special attention to this area.
The next photo showed the internal structure of the woman's genitalia. A long speculum connected to a vaginal mirror fully displayed the interior of her vagina.
"The vagina is the organ for sexual intercourse, as well as the passage for menstrual blood and childbirth. It contains numerous folds, giving it excellent extensibility and elasticity."
"The uterus is the organ that nurtures embryos and fetuses and produces menstrual blood. Located centrally in the pelvis, it is shaped like an inverted pear. In most women, the uterus is in an anteverted and anteflexed position. When not pregnant, it is roughly the size of an egg."
"The fallopian tubes are where the egg and sperm meet and combine, and they serve as the passageway for transporting the fertilized egg."
Ovaries: There is one ovary on each side of the uterus, about the size of a walnut. They are where follicles develop and grow, and also where hormones that maintain female characteristics are secreted. After menopause, the ovaries gradually atrophy..." Mom spoke fluently, pointing at the structure on the screen.
If the woman in the photo was Principal Yan, then why were these photos included in the course material? Who took them for her? As I looked at the woman in the photos, some questions arose in my mind.
"Next, we'll talk about pregnancy. This will also help students understand how they were born." Mom switched to the next page of the course material. It detailed a woman's journey from before pregnancy to just before childbirth, including many pregnancy photos. The woman's face in the material was still blurred out. Standing at 170 cm tall with full breasts, this woman was likely still Principal Yan.
"Pay attention, everyone. These photos show the physical changes in a woman from conception, early pregnancy in weeks, to the mid-term in months, and finally just before childbirth." Mom continued switching through the course material. The photos were taken and recorded at different time intervals, and their texture appeared slightly aged, likely old photos from a long time ago. They had been AI-restored and added to the course material. The woman struck the same pose as before, clearly displaying her body for the audience. Her nipples gradually changed from a soft pink to a deep red, and finally to a dark purple. The areolas also expanded in size over time. As the woman's belly grew larger, her labia darkened with each time she spread her vulva, and the secretion of vaginal fluids increased. Her figure also became slightly fuller, but it didn't detract from her good physique at all. In fact, with a bit more flesh, her breasts appeared even fuller, and her thighs became more sensual.
"You can just take a quick look at these. Later, when you get into university, there will be specialized physiology and hygiene courses for you to study." Although Mom was a professional teacher, she probably hadn't taught such an embarrassing topic in front of so many people before. As she spoke these words, her face flushed slightly with embarrassment.
"Now let's look at the psychological changes and process this woman went through after becoming pregnant. Students, it's important to have a proper perspective on these matters. Sex is not some terrifying monster. Only by explaining things clearly to you now can we ensure you won't make mistakes or feel lost in the future! Establishing healthy attitudes toward sexuality should start at your age!" Mom suddenly became passionate, advancing the PowerPoint to a set of maternity photos. The woman in the photos, despite her large belly, seemed unaffected in her mood for the shoot. The pictures looked bright and sunny, radiating warmth. Wearing loose maternity dresses, the woman appeared confident. Perhaps limited by the social conditions of the time, the photos weren't taken in a studio but rather on streets, alleys, and between buildings. Though not as polished as today's photos, they had a unique, down-to-earth charm. What struck me as odd was that the woman in the photos was always alone, with no sign of her husband. But then it occurred to me—if the woman was Principal Yan, it made sense that Wang Sen wouldn't appear.
"I hope all students can develop a proper understanding of sexuality—don't fear it, face it head-on. Thank you!" Mom concluded her speech and stepped down from the podium, marking the end of the livestream. After the lecture, the classroom fell into a calm silence, with students quietly returning to their exercises and test papers without the earlier snickering.
After school, I went home early. Since Mom wouldn't be back until late anyway, I ordered takeout and started playing on the computer.
"Did you guys seriously watch that lecture this afternoon?" The group chat buzzed to life again.
"Yeah, we did. Aren't we about to have our coming-of-age ceremony? There's always a sex education lecture around this time every year. Why are you making such a big deal out of it?"
"Damn, it's not about the lecture—it's about the PowerPoint Ms. Sun used, that pregnant woman!"
"What about the pregnant woman?" Knowing it might be Principal Yan, I quickly chimed in.
"I have resources on that pregnant woman. She's really something!"
"What kind of resources?" I pressed.
"These are probably ancient resources. I don't know the full story, but someone shared a package from overseas before. It includes photos of this woman from before pregnancy all the way to just before giving birth. The set of photos Ms. Sun showed today is in there—I recognized it immediately. If any of you want to see, I can send you a copy. It's in my cloud storage. The resources are pretty old, so they're a bit blurry. The woman has a great figure, but none of the photos show her face."
"Send me a copy!" I already suspected it was Principal Yan, so whether the photos showed her face didn't matter much to me.
"I'll send it to you privately. It might not be complete, but this woman is top-tier." The classmate sent me the cloud storage link.
