Chi Xingyu was stunned for a moment, and quickly covered the draft paper with his hand, his ears under his broken hair were slightly red.

Tong Sui remembered that he had done this kind of thing before, and said with a smile, "Don't block it, I've already seen it, it's all my name."

Chi Xingyu's Adam's apple rolled, and he took his hand down.

Tong Sui didn't turn the page, but started to list the formulas in the blank space of the same paper, and finished the problem-solving process of a problem very carefully.

Chi Xingyu looked at the paper full of names, and there were Tong Sui's handwriting, and there was a subtle harmony between the two on the same paper.

Tong Sui explained the most basic formulas and principles, "Do you understand?"

Chi Xingyu hummed.

He was originally more sensitive to numbers than ordinary people, and he could get through with just a little bit of dialing, so he didn't need to spend too much effort to continue teaching.

Tong Sui watched him write a few questions, and went back to bed with peace of mind.

Chi Xingyu finished the rest of the questions one after another, very fast. After closing the pen cap, he threw all the paper he had written into the trash can, only looking at the paper he wrote when he was a child.

He picked out the piece of paper individually, folded it carefully and put it on the last page of the exercise book.

The night was thick.

Tong Sui fell into a drowsy sleep, and suddenly felt another body temperature sticking to his back, separated by a very close distance, and carrying a cold fragrance after washing.

This bed was smaller than Tong Sui's original bed, and the two boys slept on it, which seemed a little compact.

Tong Sui rolled up subconsciously, shrinking himself into a ball, only occupying a small space.

The narrow skylight on the ceiling is passing through the cool moonlight at this moment, falling on the side face of Tong Sui, and the thin shadows cast by the slender eyelashes are as quiet and beautiful as the moonlight.

Chi Xingyu stared at it for a long time, but still couldn't figure out why someone could grow in his favorite spots everywhere.

She's so cute even when she's sleeping.

He lay down on his side with light movements, smelling Tong Sui's dry, soft and fragrant hair after washing, and unconsciously moved forward a little.

The tall bridge of the nose was almost buried in the white neck.

Tong Sui felt a little itchy from the movement behind him, and became more conscious, "You've finished writing."

The voice is soft and waxy from sleep.

Chi Xingyu almost stuck his whole body against Tongsui's slender back, passed Tongsui's hand through, hugged him from behind, and said in a low voice, "Thank you senior for teaching me, senior is really amazing."

His voice was deep, speaking in such a quiet environment at night, there was an extra layer of mystery that was not very serious and easy to associate.

Received Chi Xingyu's compliment, Tong Sui was inexplicably a little embarrassed, hummed in a low voice, and looked extraordinarily well-behaved and kneadable.

Chi Xingyu's already restless nerves were provoked by him, and he shouted again, "Senior."

Although Chi Xingyu was a few months younger than him, he looked fiercer than him, was colder than him, and spoke with an extraordinarily indifferent voice.

But he called him hoarsely in the middle of the night.

"Senior."

Such a confusion of identity and image inversion made Tong Sui feel a little stunned.

Chi Xingyu is not the kind of obedient school brother who is dynamic and sunshine. It is more like not going to wear school uniforms. He will always follow a few followers to bully the bad students.

Even the shouting people have bad and bad thoughts.

Tong Sui didn't dare to respond to him very much, holding his eyes closed and randomly.

But his skills to sleep were too bad. Chi Xingyu was so close to him, and naturally he could feel that his body slowly tightened.

"Are you going to sleep?" Chi Xingyu asked.

Tong Sui sounded.

Chi Xingyu did not want to let go of his meaning, holding it tightly, and couldn't get out of his hand. The only thing Tong Sui could do is to hide in the quilt, and his head was buried in a hot quilt.

But the more he hides, the more he will grow the badness of a certain vicious dog. He lowered his head, and his thin lips and the tip of his nose touched the clean and white nape of his neck.

He hadn't done anything yet, so he felt that Tong Sui trembled carefully. Whether it was his ears or neck, he was his sensitive area.

Chi Xingyu opened his mouth, and the tip of his teeth was grinding the skin, and he was unwilling to let go of the child who was shy to drill under the bed.

"The seniors are so hard, how can I not express it as a student."

Tong Sui closed his eyes, listening to the vague and ambiguous voice in the silence of the night, and kissed the red ear tip along his neck.

He felt that his shoulders were held by a big hand, and the whole person was easily turned around, looking face to face to face Chi Xingyu's dark eyes.

Tong Sui's eyelashes were covered with fine water mist, and his palm was against his approach, like a cute kitten with a stubborn resistance.

Chi Xingyu couldn't help rubbing his hand, very soft, because he was moist in his heart.

Tong Sui opened his mouth and opened his mouth, and his cool lips came up and touched it first, and then seemed to be able to explore.

He has no sleepy now.

The water on the eyelashes lingling under the moonlight, the pearls in the deep sea are round and clear.

Chi Xingyu kissed his lips, against his back of his head, without any room for convergence, as if the camera full of the house was nothing.

Tong Sui was very scared. If many people were seen by many people, it would really die.

Chi Xingyu Mingming is the star e -sports player who often wants to be under the eyes of the public. He should pay more attention to his image. At this moment, there seems to be no one who is more devoted than him. He can't wait to immediately occupy Tong Sui as his own.

Why don't he be afraid at all?

In the narrow room, there is only the sound of kissing. It is blushing and heartbeat. It is always strong with Chi Xingyu to play games. It can always master the situation quickly.

Tong Sui's hand was also pulled by him, and the corner of his eyes was red like a routing rouge, and he slowly bloomed on his cheeks, and his fair skin was light pink.

Obviously, thought about it to stay away from Chi Xingyu at night, and ignored him anymore, but now was kissed in bed.

The fog at the bottom of Tong Sui was condensed into tear, and it seemed to fall off at any time in his eyes.

Chi Xingyu always retreated to a little bit, let go of the lips that were familiar with, but his eyes were reluctant to move from Tong Sui's body half a point.

Tong Sui breathed his mouth and was stretched to the normal, and the tears fell one by one.

"I will never teach you anymore ..."

What he said was not powerful, but it seemed like he was gambling.

Chi Xingyu felt that Tong Sui's heart was about to be melted away by Tong Sui, and he obviously decided to stop here, but seeing Tong Sui's cute appearance, he couldn't help but move closer to him again, using the lips that had just bullied him,Kissing away the tears on his cheeks.

"Senior, you are still so cute when you cry."
