4 I have to Tianyu is indeed a nasty billet, if you cultivate it well, the future will be limitless.

"Okay, my godsister will talk to you about what happened to you at school in the past half month. ”

Tianyu's heart is divided into two uses, while accompanying Lin Yushi to tell him how he came to school, while stroking Lin Yushi's buttocks with his flexible salty pig hand, touching Tianyu is called a cool, Tianyu thinks that now is the happiest time since he was born, and he has never been so happy as today. The allure of the godsister Lin Yushi is too much, and the skin is very delicate and silky, Tianyu feels as comfortable as touching the satin, the skin on the buttocks is about to be rubbed out of the water by Tianyu, and at this time Tianyu also knows why women are made of water.

Lin Yushi was too worried about Tianyu's physical condition, Tianyu was so unscrupulous to touch her buttocks, she didn't even notice it, she really loved it deeply.

Touching Tianyu, he felt that he was about to lose control, if he touched it again, he didn't dare to guarantee that he wouldn't press Lin Yushi under him, and it wouldn't look good at that time.

After making a difficult choice, Tianyu still decided to calm his desires first, otherwise it would be no different from beasts.

Accept it when you see it, this is Tianyu's advantage, without this control ability, Tianyu would not be able to live until now. You must know that Tianyu's every experience is a brush with death, and the only thing he hasn't experienced is male and female love, so Tianyu still yearns for it. Even if Tianyu is an ordinary teenager, the desire for the opposite sex is a normal thing, not to mention that Tianyu is not an ordinary teenager.

"Godsister, you don't know how hateful that Wang Cannon is, if you see him, you will definitely have the urge to beat him. ”

Tianyu reluctantly took back the salty pig hand, and then told Lin Yushi about his experience at school.

"Xiao Yu, is that Wang Pao really so hateful?"

Lin Yushi smiled evilly.

"Isn't it, Xiao Yu never lies. ”

Tianyu Road.

"Are you interesting to Bai Yerou, the squad leader of your class, otherwise Wang Pao can hate you like this?"

Lin Yushi shook her head and said in disbelief.

"Sister, do you have to have something for Xiaoyu and Bai Yerou to be willing? ”

Tianyu pretended to be unhappy.

"No, my godsister is very lonely at home alone, I'm afraid I won't be able to keep you, where can I be willing to push you out, with Xiaoyu accompanying my godsister, my godsister won't be lonely anymore, in fact, it's not a good thing to have a boyfriend. ”

Lin Yushi looked at the swimming fish decorative mural on the wall and said a little melancholy, it seemed that she had something on her mind.

"Sister God, having Xiao Yu will definitely not make you lonely, Xiao Yu will think of the law to make you happy, when Sister God is tired, Xiao Yu can give you a hammer and shoulder massage, relax and relax, anyway, Xiao Yu has a lot of funny skills, which can be described endlessly. ”

Tianyu is really not ashamed, he pretended to be like a teenager in front of Lin Yushi, he really convinced him, fortunately, Lin Yushi didn't know the details of Tianyu, and he could let Tianyu play casually, and Lin Yushi cared too much about Tianyu, Tianyu was a child in front of her, so Tianyu's childish performance did not make Lin Yushi have any doubts, how could Lin Yushi think that Tianyu would have such evil thoughts about herself. Lin Yushi is as pure as a blank sheet of paper in terms of men and women, so Tianyu has the opportunity to act recklessly.

Yes, Tianyu is very lucky, and he can get along with such a godsister day and night, and the fairy will be envious when he sees it.

"Xiaoyu, you sit on the sofa and take a good rest, and my sister will continue to cook, otherwise our sister and brother will drink the northwest wind at night, and my sister will not be able to sleep when I am hungry." ”

After giggling, Lin Yushi walked into the kitchen and continued to cook her meal.

Tianyu is happily waiting for the fragrant meal made by the beautiful sister, while eating the fragrant meal made by the sister, while admiring the beauty that is more appetizing than any delicacies of the mountains and seas, how beautiful this life is.

The meal was finally ready, and Tianyu's nosebleed had long since stopped, but despite this, he didn't go to help his godsister bring out the food, because he wanted to pretend to be sick, so that his godsister would be more considerate of him and take care of him. Originally, Tianyu wanted Lin Yushi to take care of her for the rest of her life.

Sister God finally came out of the kitchen, holding a plate of sweet and sour tenderloin with full color and fragrance, looking at it from a distance, Tianyu knew that this sweet and sour tenderloin must be very delicious, and the color was bright red.

Seeing that Tianyu's state was much better, Lin Yushi was also a lot more relieved.

"Xiaoyu, are you still uncomfortable?"

Lin Yushi asked.

"Sister, Xiao Yu is fine, but his head is still a little dizzy. ”

Tianyu Road.

"Of course I'm dizzy after so many xx, this godsister has a deep understanding. ”

Lin Yushi smiled and said.

"Oh, I see. ”

Tianyu sat on the sofa and scratched his head, and whispered evilly.

Lin Yushi knew that he must not have thought of anything good when he saw Tianyu's expression, so he snorted coldly and said, "Xiaoyu, what are you thinking, you little ghost doesn't want good things all day long." ”

"No, Xiao Yu is just pondering what Sister Gan said just now. ”

Tianyu has a serious way and a very pure expression.

"What did you say just now?" Lin Yushi was also thinking about it, thinking about it, and then her face turned red.

"Xiaoyu, don't think about this, it's all a matter of our girl's family, you can't understand it as a boy. ”

Lin Yushi really regarded Tianyu as a child, thinking that Tianyu didn't even know this, not Tianyu, even ordinary high school juniors would not be very unfamiliar with this, now it is not a feudal society. And Tianyu's experience is so rich, it's impossible not to know this little thing.

"Sister, just tell Xiaoyu about it, otherwise Xiaoyu won't be able to sleep at night. ”

Tianyu is coquettish again, Tianyu is really shameless, and he has to ask Lin Yushi to tell the things about those days every month.

In order to prevent Tianyu from getting sicker and worse, Lin Yushi is worth shaking her head and sighing helplessly, a beauty is a beauty, and the sighs on her face are so beautiful, no wonder Xi Shi is so beautiful even when she is in pain.

"Xiaoyu, you have to know these things sooner or later, if you don't even know this when you talk about your girlfriend in the future, you will definitely be laughed at by your girlfriend, the joke is secondary, if your girlfriend thinks you don't care about her, it will be miserable, godsister doesn't want to see your relationship with your girlfriend because of this. Okay, let's cut to the chase. Lin Yushi sat next to Tianyu and continued: "Actually, what's the matter, my godsister is still a little embarrassed. ”

When she got to the real scene, Lin Yushi felt that she couldn't open her mouth again, too, Lin Yushi is a very pure woman, and it is really difficult for her to say those shy-sounding words to a boy, but also her junior.

"Forget it, anyway, Xiaoyu is not an outsider, and this is also a serious matter, my godsister has the obligation to teach you, foreign countries start teaching children when they are very young, our Huaxia country is still too conservative.

"Xiaoyu, your dizziness is because you have a lot of blood, and my sister's deep understanding is because my sister will bleed a lot several times a month, which causes dizziness.

And this is a girl-specific cycle, and of course you boys don't know about it.

The few days when a girl has heavy bleeding per month are called menstrual cycles, and the blood that comes out is called menstruation.

The menstrual cycle is a woman's physiological cycle, every other month or so, the endometrium undergoes a spontaneous thickening, vascular hyperplasia, gland growth and secretion, and endometrial collapse and shedding accompanied by periodic changes of bleeding. This periodic phenomenon of eagle passage or uterine bleeding is called menstruation.

Menstruation is mainly composed of blood, endometrial tissue fragments, and various active enzymes and biological factors. Among them, fibrinolytic enzyme makes menstrual blood liquid and does not cause coagulation, and prostaglandins play the role of contraction of the uterus. In medicine, it is believed that only the reproductive cycle experienced by primates (including humans) is called menstruation, and the reproductive cycle of other mammals is called the estrous cycle, and menstruation is regulated by the reproductive hormone system, which is necessary for biological reproduction.

A woman's first menstrual period is known as menarche, and the appearance of menarche marks the beginning of puberty. The average age of women at menarche is 12 years. Genetics, diet, physical health, and many other factors can make menarche come earlier or later. The cessation of menstruation marks that a woman has entered the xx period, also known as menopause. The average age of women in the XX stage is 51 years old, of course, just like menarche, genetics, diseases, surgery and medical treatment and other factors will make the XX stage advance or delay, and it is normal to enter the XX stage at the age of 40 to 58. The arrival of stage xx at or before the age of 35 is defined as Progeria. Seeing that Lin Yushi was very engrossed, and his head was the Tao, Tianyu thought that Lin Yushi should become a doctor.

"Xiaoyu, how much do you understand what my godsister told you?"

Lin Yushi seemed to test Tianyu. "Sister God, you are really knowledgeable, you know so much, it is the first time Xiaoyu has heard of this, it is really a long insight. Sister God, Xiao Yu doesn't understand a few words very well, I hope Sister God can explain it to Xiao Yu. ”

Tianyu said with a studious face.

Seeing that Tianyu is so studious, Lin Yushi is of course very happy, it seems that Tianyu is going to be admitted to Huada and Jingda.

"Xiaoyu, you ask, my godsister will definitely answer for you carefully. ”

Lin Yushi smiled and said.

"Godsister, won't your large amount of blood also flow out of your nostrils, it's too terrifying, if it's nothing at home, if it's at work or outside, then it's troublesome?"

Tianyu looked very worried, and his hands were clenched tightly.

Tianyu's words made Lin Yushi stunned as if she had been hit by a thunderbolt on a sunny day, and she was obviously an eagle with Tianyu. Dao discharged, why did Tianyu still come out of such ridiculous words flowing from his nostrils. Lin Yushi even began to suspect that Tianyu had a problem with his hearing or IQ.

"Impossible, Xiao Yu looks very healthy. ”

Tianyu would never have thought that his godsister Lin Yushi would treat him as an idiot.

"Xiaoyu, were you distracted just now, my godsister is obviously aware of this kind of periodic eagle. The phenomenon of bleeding or uterine bleeding is called menstruation. That is this large amount of blood from the eagle. Why do you still go out of your nostrils?"

Lin Yushi couldn't help but ask.

Unexpectedly, Tianyu's answer was even more shocking than just now, and Lin Yushi was almost scared.

"Sister, Xiaoyu doesn't know about eagles. Where is the Dao, so I guessed that it was the nostrils, and if it wasn't the nostrils, Xiaoyu couldn't guess where there was still a lot of bleeding. ”

Tianyu said with an innocent face, looking at him very pitiful.

Lin Yushi suddenly felt that she was wrong to blame Tianyu, but she didn't expect Tianyu to be so pure, so big, Lian Ying. I don't know what the Tao is, Huaxia's conservative thinking kills people, even if he puts a beautiful woman in front of him now, he doesn't know what to do. It's not very embarrassing to talk about a girlfriend like this.

Thinking of this, Lin Yushi felt that it was necessary to conduct a comprehensive sex education for Tianyu, otherwise Tianyu was afraid that it would be abolished.

As soon as he thought of this, Lin Yushi said: "Xiaoyu, didn't your school teacher tell you any knowledge about this at all? Lin Yushi was slightly angry: "Xiaoyu, it's not good to be a godsister, it's wrong to blame you, you are so old, it's time to know the physiological aspects of men and women, otherwise what will you do if you get married in the future, it's really sad." Forget it, it's useless, my sister will teach you the necessary knowledge in person, my sister used to learn it secretly, otherwise I'm afraid that you will be the same as Xiaoyu now, and you don't know anything about the physiology of men and women.

Hawk. The tract, commonly known as the uterus, is a muscular duct composed of mucosa, myometrium and adventitia, which is stretchable and connects the uterus to the external genitalia. It is the xx organ of the woman and the conduit that expels menstruation and delivers the fetus. The lower part of the Eagle Road is narrower, and the lower end is opened in the Eagle Road vestibule with the Eagle Road opening. In the Virgin, Eagle. The periphery of the crossing is attached with a hymen, which can be ring-shaped, half-moon-shaped, umbrella-shaped, or sieve-shaped. After the hymen ruptures, the eagle. There are hymen marks around the crossing. ”

When Tianyu heard this, his lower body had already xx, and it was abnormally stiff, this was the strongest xx in Tianyu's life, Tianyu only felt that his lower abdomen was hot, and his lower body was swollen and painful.

But at this moment, Lin Yushi was sitting beside him, and it was impossible for him to let Lin Yushi see his embarrassment, so he put his hands on top of xx's swollen lower body to cover up.
