My student is not a problem

The effect is actually much better than what was prepared earlier.

The weather in the city in winter is not very good, and there will always be some cold icy rain outside, and it is easy to get sick if you walk from the outside to the heated room.

Fortunately, the members of Class A are all in good physical condition. Today, except for Lemon, who did not come to the laboratory, the rest are here.

After talking about a few important knowledge points in the physics textbook in his own way, Xu Mo suddenly noticed that the pantyhose on Hao Wenrou’s legs...that is, a kind of silk stockings. strange.

After she was able to show her nature unscrupulously in the class, she really tried real campus life with the help of Xiao Jiu, such as wearing school uniforms. She was still very resistant to the feeling of not accustomed to wearing skirts at all. After I felt that way, I finally got used to it.

But she still seems to complain that the skirt is lighter than the pants, so Xiao Jiu recommended pantyhose to her.

If you put on pantyhose in the skirt, there is no problem. For the careless Hao Wenrou, it is equivalent to putting a skirt over the pants, and the burden on her heart is much lighter.

Although it is actually silk stockings.

Because of the rain today, and her chic walking style, after all, she would not be as careful as other girls to avoid the rain, so she got a lot of rain when she came.

The main reason is that the stockings on the legs are all soaked, and the naked eye can see that the black stockings are close to Hao Wen's tender thigh skin.

"Student Hao Wenrou, take the stockings... take off the pantyhose. Isn't it uncomfortable for you?"

PS: Teacher Liu is almost there...I really didn't mean it -3-....I will write about my daughter immediately.

Chapter 446: Stockings and Physics

Hao Wenrou naturally wondered why Xu Mo wanted her to do this. In her opinion, it was actually a matter of carelessness.

Uncomfortable?It used to be strange to wear silk stockings and finally got used to it a little bit, but now it can’t be said to be too uncomfortable.

As a female man who has been nurtured by such a family since he was a child, Hao Wenrou has no feeling about it at all, so she won't be like ordinary girls who are twisted because of some wetness.

After Xu Mo said these words, the teacher was silent for a few seconds before realizing that his statement seemed strange.

In class, you shouldn’t lose your face as a people’s teacher. Xu Mo pretended not to know anything, and deliberately cleared his throat, and calmly said again: "Ah...Hao Wenrou, all your socks are wet. It is very uncomfortable to stick to the body and it is easy to get sick. Go to the locker room downstairs to take it off as soon as possible. The heating in the classroom will not be too cold."

This was Xu Mo's original intention from the beginning. No matter how lawless he is, it is impossible for the public to say anything strange in the class.

As an excellent teachers of the people, care about students... Is there anything wrong!?

Besides, the soaked stockings have completely lost the faint temptation of the original girl, completely lost the original feeling, and changed the taste!Not halal at all!

Such stockings are not girls' stockings!

It should have been taken off the tender thighs quickly and handed over to the teacher to dry it completely and put it on again.

Of course, this was all Xu Mo's inner struggle, and he didn't dare to really let him do this.

"It's just a trivial matter, a little rain is nothing." Sure enough, Hao Wenrou didn't care about this at all.

Although taking off the stockings is just a casual matter, after all, Hao Wenrou has a kind of stubbornness in her bones. If she wets her clothes because of a little rain, she cares so much. It would be too lost to spread it out. She is a dignified underground world. The eldest sister of the Hao family.

"It's hard to stick to your body, right?"

Hao Wenrou continued to shook her head: "It's not uncomfortable, it's nothing."

Xu Mo glanced down at Hao Wenrou’s legs under the desk. The velvet stockings were soaked and stuck to her thighs, and felt uncomfortable for her. Usually it is already very uncomfortable for her to wear sports shoes and socks on rainy days. Not to mention that she is now like this below the waist. I don’t believe that she is really uncomfortable. It can be seen from the small movements of her legs that are worn to remove the restlessness. Even if she can bear it in her heart, her body is There will be such an instinctive reaction.

Think of a way?

As soon as he had such consideration, Xu Mo flashed a thought that felt great.

Although Hao Wenrou felt pitiful to do this, but it was for her good after all. This is not to trick her.

The most important thing is that now is the time for physics class. Well, it is very realistic, and it just lacks a good subject.

Xu Mo smiled slightly, and after passing through his thoughts a little bit, he said, "It just happens that we are in a physics class in this class, so we will discuss this matter according to the physics method, and treat it as a small part of the class. Interact, don’t be too nervous."

Hao Wenrou is undoubtedly the weakest in class. Although her standard is now much better, it has become a junior high school level compared to the elementary school level at the beginning, although she is currently in high school.

Hearing physics and mathematics...she felt dizzy and confused.

Not afraid of the sky, not afraid of it, she who dared to break into the enemy's nest alone to get a hundred enemies, she was a little afraid of these things, so that when Xu Mo just made this suggestion, her body suddenly tightened and looked very nervous.

"Will... do a question?" Hao Wenrou asked in a panic that pressed her heart.

"It's not a problem, don't worry. Just let us use the knowledge points in the physics textbook to discuss and analyze the following... about your stockings. The physics knowledge can be used cleverly on this, and everyone will listen together. When you listen to it, don't forget that we are still in class." Teacher Xu's class seems to have improved somewhat.

"...Analyze what?" Hao Wenrou felt a little dizzy in his opinion.

The rest of the students were also curious about how Xu Mo connected the stockings with the physics problem.

"We are reasonable. Take dry stockings and wet stockings, what happens when you wear socks? It's a point of physics knowledge."

Hao Wenrou naturally couldn't answer, because her eyes had turned into dizzy circles.

Fang Zhizhi next to him is very spiritual, so he replied smoothly: "Friction."

Teacher Xu nodded with satisfaction: "Yes, it's friction. Since it's related to friction, how do you prove the difference between dry socks and wet socks?"

Because this question was originally very strange because Xu Mo randomly sprouted it in his mind. Only he knew what it was like, and naturally others couldn't answer it.

Fang Zhizhi and other classmates also shook their heads, not knowing.

Not to mention Hao Wenrou, who has completely lost his mind.

Teacher Xu smiled confidently and told everyone the real explanation.

"When you wear silk stockings, you need to consider sliding friction. The magnitude of sliding friction is related to two factors: the coefficient of dynamic friction μ and the positive pressure N, and the force F=μN. Because the wet stockings contain water, the water droplets are different. Directional tension, as well as its own gravity, will increase the positive pressure on the legs. This is the main one. Secondly, because water is an infiltrating fluid, the coefficient of dynamic friction also increases. So it is not easy to wear wet stockings. , Let alone wearing it all the time... Well, classmate Hao Wenrou, after all, we are still discussing whether you should take off the stockings temporarily, or I will explain to you the wet stockings. What is the difference between wearing dry stockings on the legs and using physical knowledge to explain?"

Hao Wenrou always seemed to have been given a fixation technique just now, especially Xu Mo was even more dizzy when he was reciting the inexplicable and terrifying formula. It was not until Xu Mo said she wanted to continue.

Whether or not she is the invincible big sister in the legend, she is actually just a little girl.

She was so frightened by Xu Mo that she immediately stood up in front of Xu Mo's face, and hurriedly reached into her skirt with a small hand and pulled the pantyhose down from her waist, because the movement was too fast and too hard. The underwear straps on the waist were pulled down together.

But it didn't matter, she had to lift her leg when she took off her pantyhose, Xu Mo had already seen it when she lifted her leg.

Xiao Jiu is awesome, Hao Wenrou is really under her guidance instead of wearing that wicked boxer briefs, instead of wearing underwear?Or is it pink with small flowers?Not bad……

A whole pair of warm...the tights that were particularly hot somewhere was delivered to Xu Mo's hands.

"Don't... don't! I just take it off!"

Her lines are a little strange.

However, Xu Mo also took it subconsciously.

Originally wanted to scare Hao Wenrou to let her obediently change out the soaked stockings, never thought that she would react so badly and just take it off on the spot?Throw it directly to yourself?
