[Short Story] An Accident in the Physiology and Hygiene Class (Student Campus Adult Fiction)

"Knock knock..." Accompanied by the pleasant sound of high heels, Teacher Xiaoyue stepped into the classroom door. After a while, the noisy class gradually quieted down. Every time Teacher Xiaoyue appeared, the boys' eyes always lit up. Not only the boys, but all the girls in the class were always secretly paying attention to Teacher Xiaoyue's outfit, secretly comparing and imitating her.

Today, Teacher Xiaoyue wore a moon-white cotton dress with a yellow hairpin in her hair, revealing her youthful vitality. Her two slender arms showed her fair skin, which faintly revealed the color of jade, crystal clear. What is even more attractive is the two slender legs that are exposed from under the skirt. She is not wearing stockings, and is barefoot with a pair of white high-heeled sandals. Five snow-white toes are exposed from the front, like five petals, gently twisting with her steps. There are faint blue veins visible on the soles of the feet.

Teacher Xiaoyue has just graduated for a year and happens to teach a physiology and hygiene class. Xiaoyue is very charming and exudes a mature temperament, and there is never a student absent from her class. Today's course is reproductive health. The students arrived early. Not to mention the girls, the boys have been looking forward to this day for a long time, although many of them have already memorized the course in the textbook.

The lecture began. Just like before, Teacher Xiaoyue's lessons were always told in a leisurely manner. When she talked about the reproductive physiology of boys, the girls basically listened with their heads down and blushing faces. When talking about the female genitals, one could hear a pin drop in the class. Teacher Xiaoyue said, "Look at Illustration 11 in the book. The clitoris is covered by the foreskin on the upper part of the vulva. It is a sensitive area of ​​the female sexual organ. Although it is very small, the nerves distributed in it are similar to those of the male glans. When stimulated by the outside world, it will erect like a male penis..." At this time, Zhang Peng, who was sitting in the first row, stroked his glasses curiously and looked up at the teacher. His deskmate Li Xia immediately knew that he was going to ask another question - "this nerd", Li Xia cursed inwardly, he dared to ask any question!

Sure enough, Zhang Peng asked, "Teacher Xiaoyue, when the clitoris is erect, will it be as big as the penis? Then what's the difference between it and a boy's?" Teacher Xiaoyue blushed, and then said calmly, "No, the clitoris itself is very small, and it won't become very large after erection." "Oh, how big is it?" "Probably... this big..." Teacher Xiaoyue gestured with her hands.

"It would be great if there was a real thing to compare with. I know what a penis looks like, but I've never seen a clitoris..." As soon as this nerd said this, the class suddenly burst into laughter, and even some girls couldn't help laughing with blushing faces.

"Oh, this..." Teacher Xiaoyue hesitated, lowered her head for a moment, and said as if she had made up her mind:

"How about this, today we can use real objects to explain to you, just so that you can better understand the physiology of girls. However, this goes against some social ethics and morals. I hope you will treat it correctly and not tell anyone!" As soon as the words fell, several boys with quick hands and feet immediately closed the doors and windows and drew the curtains. The atmosphere in the classroom suddenly changed, and everyone stared at Teacher Xiaoyue.

Teacher Xiaoyue bit her lip, her white teeth flashing: "The teacher is four or five years older than you, and more developed than you. Take the teacher as an example..." Teacher Xiaoyue turned her back, reached under her skirt with both hands, and pulled down her panties. Her white and plump thighs flashed by, and several girls noticed that Teacher Xiaoyue was wearing formal and popular black hollow panties. Although Teacher Xiaoyue quickly rolled them into a ball in her hands and stuffed them into her bag, she still couldn't escape the girls who saw it.

It is said that the Japanese invested in a Chinese porn website. I finally got it.

Let's go to happy together. There are many sexy girls inside.

The whole class seemed to hold their breath, and the teacher spread out two slender fingers and explained:

"This is the labia majora, which has pubic hair on it... These two are the labia minora, which protect the vaginal opening. After more sexual activity, pigmentation will accumulate and turn black..." Zhang Ming asked, "Teacher, your color should not have any pigmentation now, right?" Teacher Xiaoyue raised her eyes and glanced at Zhang Ming, with a flash of red on her face. "Not... that much." "Then" Zhang Ming continued to ask:

"Where is the teacher's hymen?" Teacher Xiaoyue's face turned completely red. "The teacher's hymen is gone. We can see which female student can demonstrate it later..." After saying that, she looked up at everyone, and many girls immediately lowered their heads. "Zhang Peng, look, this is the clitoris, under the foreskin..." "Teacher, what's the wet thing on your labia, is it urine?" The teacher's face, which had just recovered a little, suddenly turned red again, and she said shyly: "No, it's the fluid secreted from the vagina, which helps the insertion of the penis. It will be secreted during sexual excitement..." "Then what are you asking now..." Even though Zhang Peng was a nerd, he felt that his question was inappropriate. "Teacher, you said that the clitoris will erect when excited. What does it look like?" Teacher Xiaoyue bit her lips with her shining teeth again. "Okay, you watch." After that, she began to gently rub the clitoris with the tip of her right middle finger. At the same time, her left hand pulled up the vulva. The teacher's slender fingers rotated rapidly. The fingers painted with flesh-colored nail polish were white with rosy red. It can be seen that the teacher's movements are quite skillful... "Ah-" I don't know when, Teacher Xiaoyue's cheeks were already covered with blush, "Student Zhang Peng, you, did you see it? Ah-has the teacher's clitoris become bigger? Ah, the teacher is about to climax! Ah, ah, well, I can't stand it, oh-" With a long moan, Teacher Xiaoyue's face became a little distorted, her beautiful face wrinkled, her neck hooked up and stared at her lower abdomen, and then she fell on the desk again. The classroom was very quiet, with only the sound of heavy breathing coming and going.

After a minute, Teacher Xiaoyue slowly sat up and glanced at the classmates embarrassedly. "Did you see that? The teacher just demonstrated the structure of the female sexual organs to everyone." Then she began to put on her underwear. Zhang Peng noticed sharply, "Teacher, your water has flowed onto the table..." The teacher blushed, "Well, this is also a normal physiological reaction. Now, who will demonstrate the external genitalia of a boy? Liu Feng, how about you come?" Teacher Xiaoyue had already noticed on the stage that Liu Feng was sitting there with his crotch pushed up by his erect penis.

Liu Feng hummed and stood up with a red face, his body obviously hunched over. Teacher Xiaoyue couldn't help but smile and said, "It's okay, it's all for the sake of making everyone learn better. Come on, take off your pants and come to the teacher." Liu Feng responded by taking off his pants and underwear, only to see a long cock popped out of his crotch, swaying up and down with a red face. The girls on the left and right glanced at it, all blushing and lowering their heads.

Let's go to happy together. There are many sexy girls inside.

Liu Feng, wearing a white shirt and with his lower body naked, walked to the podium and faced everyone.

"Next, please allow classmate Liu Feng to demonstrate the process of male ejaculation. Everyone should observe carefully..." "Ah, this, what, I can't..." Liu Feng said hurriedly. Teacher Xiaoyue said, "This is a very rigorous thing. Don't have any other concerns." Liu Feng had to use his hands to pick up his dejected little brother. After a few strokes, the little brother was still limp. Liu Feng looked up at Teacher Xiaoyue with a bitter face, "No, teacher, I..." Teacher Xiaoyue covered her mouth and smiled, "Haha, it seems that someone needs to help you, so..." The teacher looked up and looked for "Wang Fang, come up!" Wang Fang is Liu Feng's desk mate. She loves to chatter the most. She is a crazy girl, but she is very beautiful, even a little coquettish. Boys love to joke with her. Wang Fang pouted and said, "I won't! Why should I? I won't touch that thing of his!" Teacher Xiaoyue smiled and said, "If you don't want to touch it, then, when the teacher was demonstrating to everyone just now, who put his hand into Liu Feng's pants?" The classmates in the classroom all laughed, and Wang Fang's face turned red. She stood up shyly. She was wearing a miniskirt today. From the back, her two strong and white legs were particularly eye-catching. For some reason, Wang Fang stood up and pressed her skirt involuntarily, as if she was afraid that everyone would see something.

Wang Fang walked to the podium, picked up Liu Feng's cock, and stroked it reluctantly. It was obvious that this was not the first time she had stroked a man's cock, but Liu Feng's cock still didn't get any better, which made Wang Fang roll her eyes and mumble something in her mouth. At this time Liu Feng reached his hand into Wang Fang's collar, grabbed Wang Fang's breasts, and squeezed them. Wang Fang twisted her body, but was helpless and let him twist her nipples unscrupulously. Liu Feng's cock seemed to get better, but slowly became a little weak. Teacher Xiaoyue said, "With enough sexual stimulation, the penis will fully erect. At present, the stimulation received by the penis is not enough. This is mainly because the stimulation of the human cerebral cortex nerves is insufficient..." At this time, Liu Feng's hand withdrew from Wang Fang's collar, and reached under Wang Fang's skirt, kneading Wang Fang's plump buttocks. The classmates could vaguely see Wang Fang's white thighs and a corner of her buttocks from Liu Feng's kneading. The boys stared at her greedily, and the girls knew that Wang Fang's buttocks were very plump and upturned, so they looked at her with some jealousy.

Suddenly, Liu Feng grabbed the hem of Wang Fang's skirt with both hands and lifted it up violently. Before Wang Fang could react, her skirt was taken off. Wang Fang was left with only her underwear. At this time, Wang Fang screamed, "What are you doing! - Hateful -" "Hehe, the teacher said, you didn't stimulate me enough? Besides, just now, your panties were wet, I touched it..." Wang Fang blushed, and said "Pooh", and took off her panties with both hands. The sharp-eyed boys saw that there was indeed a wet spot in the middle of the panties, and the girls noticed that the brand of Wang Fang's panties was the same as the teacher's, except that the teacher's was black lace and Wang Fang's was a black thong. Wang Fang took off her panties and threw them at Liu Feng's head, who burst out laughing. Wang Fang was still an outgoing and courageous girl. Although a little shy, she regained her personality at this time.
