Since we are going to play, let’s play it well. Ning Wenru stood up and shouted energetically: “Class begins!”

"Stand up!" Pang Zaiyuan reacted very quickly, and stood at attention immediately, with his shoulders pulled back, his chest straightened, and his fingers stretched out in a very straight posture. Then, Pang Zaiyuan said with a serious face: "Good evening, teacher~ Oh~"

He was standing so straight and serious, with the appearance of a well-trained soldier, but he was playing games with him!

What a contrast! Ning Wenru couldn't help but laugh, then pinched his face with both hands, trying to look more serious, and said in a calm tone: "Good evening, classmate. Okay, the class is about to start. First, let's review what we talked about in the last class. I wanted to let classmate Pang know me better so that I can have a better interview. But classmate Pang only completed a small part of the assignment last time."

"Yes!" Pang Zaiyuan held his head high and announced in a deep and powerful voice, just like he was announcing the number of troops during military training: "The teacher did not explain in detail, so the students felt they had no idea where to start. Teacher Ning, please show us first. It is best to lead by example and teach step by step. Only after the students have observed carefully can they understand more easily."

Look at his serious and solemn attitude, yet he said such words! Ning Wenru almost burst out laughing, but he held back and said, "Okay, the teacher is setting an example, so you don't have to be too nervous. Classes are not like training, so you can relax a little. Student Pang, go get the ruler on the table."

"Okay," Pang Zaiyuan went to get the 30-centimeter stainless steel ruler, moved a stool and placed it behind Ning Wenru, and said, "Teacher Ning, you must be tired. Please sit down."

This student is very smart!

However, Ning Wenru did not sit down immediately. Instead, he directed Pang Zaiyuan to move the stool to the bathroom door, and followed him there. He said solemnly and honestly, "Okay, now continue with the homework you didn't finish last time. The teacher will teach you step by step."

"Okay, Teacher Ning." Pang Zaiyuan quickly took off his black sweater and walked into the bathroom wearing a white shirt.

Ning Wenru also walked in, walked under the shower, and said, "Student Pang, please sit on the stool, take a good look, study hard, and don't disturb the teacher's teaching work unless necessary. Sit still so as not to affect other students."

"Yes!" Pang Zaiyuan walked out and sat upright on the stool at the bathroom door, his back straight, his hands placed neatly on his knees, his eyes fixed on Ning Wenru, his attitude towards learning was very serious!

Ning Wenru turned around and adjusted the water to warm it up, saying, "It's wet, will we still have couple outfits to wear tomorrow?"

Pang Zaiyuan swallowed, his Adam's apple rolled, and his deep voice was a little moist: "There are still a lot, I bought a few new sets, I can change them every day."

"Then I'll wet it." Ning Wenru prepared warm water, picked up the showerhead, and poured it from the left shoulder to the right shoulder. The warm water wet the white stand-up collar shirt, turning the upper part of the shirt translucent, revealing a large area of ​​white skin, which was tightly attached to the flat chest, but not transparent; the lower part was not completely wet, only translucent water marks appeared one by one.

The steam was rising, creating a hazy beauty that made Ning Wenru's skin look even whiter and more moist. Pang Zaiyuan, who was ordered to sit still at the bathroom door, couldn't see clearly at all. His body suddenly leaned forward, his buttocks hanging in the air, but he sat back immediately, his hands clenched his knees, and his trousers were wrinkled like spider webs.

Ning Wenru reminded: "Students, let me reiterate, now is the time for observation and learning, you all have to sit still and not move around, so as not to affect other students' learning!"

Pang Zaiyuan sat back firmly and said in a deep voice: "Learning by watching alone is not effective. Practice makes perfect. Please teach me step by step, teacher."

Although he spoke with great integrity, the magnificent pen hanging above his knees betrayed his thoughts!

Ning Wenru was unwilling to give in to Pang Zaiyuan's desire so quickly. Who could have made Pang Zaiyuan delay an assignment for so long? Ning Wenru raised his hand and Pang Zaiyuan cooperated and shut up. Ning Wenru said honestly, "Before practice, theory should be used to guide practice. Please be patient, Mr. Pang. After the theoretical demonstration, there will be an opportunity for experimentation."

Ning Wenru put his hands on the buttons of his collar and explained, "Although Student Pang has not completed his homework, the beginning of his homework is very creative. The teacher likes it very much. The part I just demonstrated to the whole class is the most creative part of Student Pang. But it has nothing to do with the main point of the homework. Now, the teacher will demonstrate it to the students. Student Pang, come here and be a prop."

"Yes!" Pang Zaiyuan was very obedient, and rushed over in a few steps, raising his hands and putting them on the outside of Ning Wenru's collar, obviously wanting to unbutton Ning Wenru. Ning Wenru slapped Pang Zaiyuan's hand with a ruler and scolded him: "Teaching props will not move by themselves."

Pang Zaiyuan put down his hands helplessly and said, "The teacher must be very uncomfortable with the clothes sticking to his body. Dry it first and be careful not to catch a cold."

Ning Wenru thought about it and realized that it was a waste of water resources to keep the shower running to maintain the temperature, so he turned off the shower and said, "Then the class is over. Leave the teaching props where they are and don't move them."

As he spoke, Ning Wenru stood on tiptoe and covered Pang Zaiyuan's eyes with a towel. He checked him carefully again to make sure that he could not peek. Then he took a quick shower and changed into his pajamas within five minutes.

Ning Wenru didn't want the tall and muscular Pang Zaiyuan to see his thin body like a bamboo pole and a small belly. He should at least train his abdominal muscles and reduce his belly so that he wouldn't be laughed at too much.

Because Pang Zaiyuan was so beautiful, whether in appearance or lifestyle, Ning Wenru admired him. Therefore, Ning Wenru was unconsciously influenced by the person he admired, and wanted to get close to him, so that he could become the person he admired, and improve bit by bit.

Ning Wenru planned to let Pang Zaiyuan teach him how to keep fit in the future, and they would exercise together every day. When there were results, he would let Pang Zaiyuan see his body. So, Ning Wenru quickly changed his clothes while blindfolding Pang Zaiyuan, and then took off his clothes, picked up a ruler, and continued to demonstrate with his own body.

He was already a junior, and the size of the penis was basically determined. Pang Zaiyuan had also eaten it before, so there was nothing to be ashamed of. So Ning Wenru took out his soft brush and measured it with a ruler.

Pang Zaiyuan stared at it and read the number: "Eight centimeters, not short."

"It's normal to be soft," Ning Wenru took out Pang Zaiyuan's and said, "You're breaking the rules! Only someone in my state can compare, so make it smaller."

Pang Zaiyuan said, "Why don't we measure it in this state first? Students are stupid and can't control themselves. Besides, they would rather the teacher measure it with his hands than with a ruler."

Ning Wenru looked up at Pang Zaiyuan and measured it with a ruler. He found that his visual estimation was very accurate. It was really 20 centimeters! It might even grow a little bigger. It was really a pen that could be proud of the whole country. Ning Wenru was very envious. He played with it for a while and filled his palm. It felt very good, but it would get dirty with ink and it was a bit sticky.

Ning Wenru played for a while, but Pang Zaiyuan didn't get smaller. Instead, he became more and more excited. He held Ning Wenru's shoulders to support his body, his muscles were tense, and he looked like he was enduring it with great difficulty.

Ning Wenru pulled it out, and Pang Zaiyuan followed behind. Ning Wenru led Pang Zaiyuan to the bedside and said, "Teaching aid, wait a moment, the teacher is going to show you another technique."

"Okay." Pang Zaiyuan, who was temporarily serving as a teaching prop, sat up straight holding a pen.

Ning Wenru washed his hands, went to the refrigerator to get the Coke he bought yesterday and a large paper cup, poured half a cup of Coke into the paper cup, and then walked towards Pang Zaiyuan.

"Student Pang, turn over and lie on your stomach in a prone position. Yes, don't bend over, you can support yourself with your arms, it's not that tiring. Straighten your legs, I'm going to put the Coke down there." Ning Wenru directed, put the paper cup of Coke in at an angle, and stirred the Coke while holding Pang Zaiyuan's pen.

Pang Zaiyuan lowered his head and adjusted his posture, his teeth clenched, the muscles in his arms tensed even more, and his shoulders bulged.

Ning Wenru asked, "Don't hold back. Tell me how it feels. Tell me in detail. I haven't tried it before."

Pang Zaiyuan opened his lips but couldn't speak. After a long while, he couldn't help but take a deep breath and finally managed to utter two words: "Cold, refreshing."

Ning Wenru kept moving his fingers, and switched to his left hand to stir the iced cola, and continued to ask: "Do you have any more detailed feelings?"

Pang Zaiyuan exhaled and said, "I can't describe it, it's just very exciting--" Then Pang Zaiyuan's face suddenly turned pale and asked, "With this expression, are you thinking about writing a novel? I checked the time, you touched my arm as soon as we met, and you wrote the feeling of touching my arm into the article written by your roommate that day."

Why are you so serious when you are reading a text? Ning Wenru quickened the movement of his fingers and tried to explain: "The teacher wants to confirm the effect of the experiment and listen to the students' ideas. After all, this experiment has never been done before, and the teacher is unsure."

Pang Zaiyuan raised the corner of his lips and said, "Teacher, just give it a try and you'll know."

Ning Wenru suddenly became excited, and rubbed his fingers on the tip of the pen a few times. Pang Zaiyuan could no longer laugh, and buried his head in his arms, his whole body tense as steel. Ning Wenru felt his thumb being washed by streams of cool pen ink, and Pang Zaiyuan relaxed, turned over and lay down to catch his breath.

Ning Wenru took a ruler and moved it over, measured it, and read the number: "Fifteen! I suspect I used a fake ruler!"

Pang Zaiyuan asked, "How much older have you become?"

Ning Wenru's voice was as tiny as a mosquito. If you didn't put your ear close to it, you wouldn't be able to hear it at all: "Fourteen."

Pang Zaiyuan regained his strength. He sat up and said with a smile, "This is only two centimeters more than the average, which is not bad."

Ning Wenru hung his head in despair, lay down, and covered his head with a quilt.

Pang Zaiyuan's voice came through the quilt: "The experimental class has started, right? Then students, help the teacher measure."

After a while, the quilt was lifted and he felt a chill on his stomach. Ning Wenru's soft teaching stick was wrapped by something, which was both cold and hot. Ning Wenru couldn't help but shivered and finally experienced what Pang Zaiyuan had just experienced!

Immersed in ice water, tiny bubbles burst one after another along the mucous membrane. Such a subtle and cool feeling cannot be achieved by any other method. And the soft and flexible tongue licked the bubbles. Ning Wenru was so happy that he was going crazy. He sat up, and his feet could not help but press against Pang Zaiyuan's shoulders, with his toes clenched.

After a while, the Coke slid down the corners of Pang Zaiyuan's lips. There was too much, so Pang Zaiyuan swallowed all the Coke in his mouth, wiped the corners of his mouth with a tissue, wiped Ning Wenru's pointer with it, glanced at him again, and said, "So you're wearing a panda today, too. No wonder you looked so weird when you saw me wiping my hair with a towel."

Ning Wenru asked, "How did you buy the panda towel? I thought you bought it because you secretly saw me wearing it."

Pang Zaiyuan glanced at Ning Wenru and said, "No, I just happened to see that you might like the pattern, so I bought it. Do I look like someone who would wipe his face with your underwear?"

Ning Wenru covered his face and changed the subject: "What did you feel just now?"

Pang Zaiyuan smiled and said, "It's sweet, mixed with the taste of cola."

Then, Pang Zaiyuan looked down and frowned, saying, "Teacher, the experiment failed."

Ning Wenru: “Ah?”

Pang Zaiyuan said sternly: "The student is too stupid. This is the first time he used Coke and he made the teacher's bottle too small and couldn't measure the big one. Please give me a chance and allow me to do the experiment again."

Ning Wenru's ears turned red, and he said, "I've agreed. There's not much to be said for this. Student Pang should cherish this opportunity to do the experiment."

"Yes!" Pang Zaiyuan answered loudly and seriously, and then gave Ning Wenru two more experiments before he successfully measured the size.

…

Ning Wenru measured all the dimensions of Pang Zaiyuan and recorded them, indirectly using up all of Pang Zaiyuan's ink and brushes, and only stopped when he had very little ink left in his own writing.

The two of them lay tiredly in the comfortable bed. Pang Zaiyuan held Ning Wenru's hand and said, "We will go back tomorrow. Today, Ningning has a happy birthday. Are you happy today, Ningning?"

Ning Wenru was actually quite satisfied today, but he still asked, "Is this all gone? Where's the cake?"

Pang Zaiyuan said, "Do you want a cake? We never have cakes for birthdays at home, so I forgot about it."

Ning Wenru said, "Oh, it's okay. I haven't celebrated my birthday for many years. The whole class always celebrates together on one day. I'm very happy that you came here on purpose today. By the way, when is your birthday?"

Pang Zaiyuan didn't blame Ning Wenru for not understanding clearly, and said: "It was on the Lantern Festival. I calculated it according to the lunar calendar, not the date on the ID card."

"I see. Your family is very traditional," said Ning Wenru.

Pang Zaiyuan said: "It's mainly because my mother is traditional and my father listens to her. My father never celebrated my birthday since I was a child. He thought that birthdays were the day of suffering for my mother giving birth to her child, so he should do the opposite and work hard for my mother to celebrate."

Ning Wenru said, "Your father is right. I'll call Mom."

"Yeah." Pang Zaiyuan hugged Ning Wenru and listened to his phone call home. When Ning Wenru was chatting with his mother, he mentioned that a close roommate had celebrated his birthday for him, and his mother was very happy to hear that.

After Ning Wenru finished the call, a question suddenly occurred to him: "Did your mother check the Moments? Would she be against us? Your father has seen me, and your parents should be very loving, but your mother didn't show up?"
