My senior sister is not a human being!

She was really nervous because the eldest lady who was best at fighting was so hard...

"There's no point in admitting your mistake." Su Yuchen took two steps forward, squeezed away Christia's beautiful black legs, and looked at Christia with deep eyes: "You didn't recognize her, did you?"

"I..." Cristia gritted her teeth suddenly.

Not only because of Spear Chen, but also because the little bad boy took a writing brush and drew a horizontal line on the slightly overflowing white leg flesh between the torn black silk gaps on her thighs.

The ink is a little cold, the brush is a little soft, and my legs are a little itchy.

"I will ask a total of five questions. You didn't answer the first question." Su Yuchen continued to approach Christia while watching the changes in her expression. After finding that there was not much difference, he leaned forward slightly and raised his nose. Almost touching the tip of her nose.

Christia's fingers holding the edge of the table were a little tighter at this moment, her face was slightly pale, but she was still within the tolerance range of education.

"Very good!" Su Yuchen praised: "It seems that you realized that you made a mistake in not studying hard. Now review the knowledge."

"That character is pronounced 'leg', do you remember it?"

"Huh... Remember, remember, legs!" Cristiana's eyes were hazy, and her red lips opened slightly: "Read the legs, I learned it."

"Very good." Su Yuchen looked down at the cross on her leg: "Good boy, can I give you a reward?"

"Good~"

As the books on the desk swayed slightly, Su Yuchen picked up the brush again, and with a steady wrist, he wrote the word "美" in front of the word "leg", and then placed it again in front of Christia: "What does this word read? ?”

Cristia, who was shaking her head slightly, tried to raise her head and opened her foggy eyes to read the words on the rice paper, but she felt that she was shaking and couldn't see clearly.

If you can't see clearly, if you don't make a sound, you just don't know.

"Alas!" Su Yuchen sighed heavily: "You don't know such a simple word. What have you been studying these days? Are you slacking off?"

"I'm sorry, Tia is a stupid, stupid student..."

"Yes." Su Yuchen picked up the brush again and drew a longer vertical line on the horizontal line on her leg: "Why haven't you studied hard these days? I just taught you the word 'beautiful' a few days ago. I passed you, thought it was easy and didn’t check randomly, but you forgot about it?”

"I'm sorry..." Christia's beautiful curved figure leaned back uncontrollably, and the warm and fair skin of her cheeks seemed to be covered by the setting sun, making her beautiful.

"Tia is an idiot, so please educate Tia..."

"I know." Su Yuchen narrowed his eyes slightly, looked at her glasses that were about to slip off the bridge of her nose, and reached out to take them off.

The face hidden by glasses fully bloomed under the light, radiant and charming.

Cristia subconsciously raised her right hand to cover her eyes: "Don't look..."

Sister Queen knows how to arouse desire.

Su Yuchen held her wrist and took it away: "Why can't you look? I didn't study hard, and when I admitted my mistake, I didn't look directly into Teacher Su's eyes?"

"look at me!"

"Well..." Christia tried her best to look at him with her misty eyes wide open: "I, I was wrong, I will study hard."

"But you have not pronounced the correct pronunciation of the two words."

"sorry."

"You only have three chances left." Su Yuchen re-wrote the word "true" after the word "leg" on the rice paper and placed it in front of her again: "The third question, what does this word read?"

"Read, read..." Cristia's slender and straight legs lined with black stockings were stretched tightly. Her small, crystal black silk jade toes were curled up, and her small red heels swayed on her toes: "Tia... no Know!"

At this moment, Christia had a hazy and soft aura all over her body, making Su Yuchen unable to take his eyes away.

Maybe it’s because Westerners mature earlier than Easterners?

Su Yuchen thought and put down the rice paper: "I'm getting more and more disappointed. I don't even recognize the word 'true' anymore. Alas!"

"I'm going to check your study status more tonight. You've really been slacking off in the past few days since I've been away!"

As Su Yuchen spoke, he took a brush and drew a short horizontal line next to the vertical line on her leg.

Cristia opened her eyes wide, her slightly opened red lips and her voice gradually weakened: "Tia... I really don't know..."

In her hazy consciousness, Christia somewhat understood why Jiang Shengyue, who was best at fighting hard, lost so quickly.

Because of a certain emotion, it never stops.

Wow…

The books, stationery, paper and pens on the table were pushed to the ground by Christia who fell down.

Su Yuchen, who was stunned for less than a second, quickly protected the back of Christia's head to prevent it from hitting the wall.

"I don't know this word"

Looking at Sister Queen, who looked like she was sleeping with Sister Yue, Su Yuchen blinked, a silent smile flashing in his eyes.

These are only three questions.

Su Yuchen thought, and wrote the last two words on the rice paper, and then the five words on the rice paper appeared: Beautiful legs are so sexy.

After finishing writing, Su Yuchen glanced at her thighs and hesitated for a moment before finishing writing the word '正'. After all, there was no chance to answer the last two questions.

Thinking about it, Su Yuchen picked up Christia and put her on the big bed in the bedroom, covering her with a quilt.

"Silly sister." Su Yuchen said softly.

Christia slept soundly.

Outside the door, Jiang Xiyu put away his phone and returned to the sofa: "Chen really knows how to play, and Tia didn't answer three questions correctly in twenty minutes."

Rao Rao blushed and lowered her head without speaking. Just hearing the voice made her feel ashamed.

"Cat Cat, do me a favor."

"Oh~"

In the bedroom, after Su Yuchen collected the books and stationery that fell on the floor, he opened the door and walked out.

For a moment, the world was spinning, and then a chill came from the surroundings.

Huh?

The door outside the house?

Su Yuchen blinked, what are you playing again?

Thinking about it, Su Yuchen knocked on the door, and the person who opened the door was Xiyu with two ponytails.

"Brother-in-law, are you back?"

……

Chapter 722 "Brother-in-law, why can my sister do it but I can't?"

"Brother-in-law, are you back?"

Looking at the cherry-haired girl with twin tails standing at the door to welcome him home, Su Yuchen immediately smiled and walked into the house: "I'm back."

"Brother-in-law~" Jiang Xiyu asked while helping him take off his formal coat, "Are you tired of being a tutor?"

"I'm tired." Su Yuchen glanced at her and smiled: "It's hard to teach stupid students. It's very tiring to check the knowledge you have taught over and over again but not be able to answer the questions."

While he was talking, he glanced at Xia Yushuang and Bai Raoruo who were sitting on the sofa. Well, it was not their turn now, so he pretended not to see them.

"How stupid are you?" Jiang Xiyu asked curiously: "Are you stupider than me?"

"You are not as smart as her, but you are more studious than her." Su Yuchen unbuttoned the top two buttons of his shirt. He turned around without hearing Xiyu's reply.

The succubus sister-in-law stared directly at the collar of her untied clothes.

Su Yuchen reached out and touched her head: "Where is Sister Yue?"

"Sister, she had a fever and fell asleep after taking an injection." Jiang Xiyu blinked: "Brother-in-law, are you tired from teaching stupid students? Do you want a midnight snack?"

"No, I'm going to see Sister Yue." Su Yuchen shook his head and walked towards the second floor.

As soon as he took a step, Jiang Xiyu stretched out her white and tender hands to grab his sleeve.

"What's wrong?" Su Yuchen turned to look at Jiang Xiyu.

"Brother-in-law, I, I, I..." The expressionless Jiang Xiyu imitated Rao Rao's shy behavior, first lowering his head, and then "plucking up the courage" to raise his head and look at him: "I made a midnight snack, and I can't finish it. , Brother-in-law, just eat a little, okay, okay?"

Su Yuchen's expression was startled, as if he noticed something, he quietly opened his sleeves and walked towards the kitchen: "Then let's eat something first."

"Yeah!" Jiang Xiyu walked with Su Yuchen towards the kitchen with a clearly cheerful pace: "Brother-in-law, these are the wontons you like to eat!"

"so good……"

When Su Yuchen walked into the kitchen, he originally thought he needed to pretend to eat, but he never expected that a bowl of hot wontons was placed on the dining table.

Although he was confused when it was ready, Su Yuchen still sat down cooperatively, picked up a spoon, scooped out a wonton and ate it: "It tastes good."

"Yeah!" Jiang Xiyu, who was sitting opposite Su Yuchen, held his chin with his hands in a calyx shape, and his twin tails swayed happily as his body swayed: "I learned it from my sister seriously, and she also said it was delicious. Woolen cloth!"

Su Yuchen laughed and asked, changing the subject: "What about you, do you think the freshman class is tight?"

"Study is tight."

Su Yuchen almost choked when he heard this, but he quickly adjusted his expression and continued: "Are you so serious now?"

"Because I'm stupid." Jiang Xiyu pursed his lips: "If I don't work hard from the beginning, I'm afraid I won't be able to get into the university of my choice."

"Which university do you want to go to?" Su Yuchen looked at her and asked.

Jiang Xiyu pursed his lips, remained silent for a while and said, "Go to the same university as my brother-in-law!"

Just say "brother-in-law", not "sister".

"Well, it's good to have goals." Su Yuchen nodded pretending not to understand: "Where did you rank in the final exam?"

Seeing that Su Yuchen didn't understand, Jiang Xiyu's eyes seemed to dim, but he still replied: "Eighteenth place, two places better than the midterm exam!"

"Not bad." Su Yuchen praised: "If you continue to make progress, you will definitely be admitted to the university where Sister Yue and I go."

"Don't mention it..." Jiang Xiyu's lips trembled, but he still didn't say the word "sister".

"What?" Su Yuchen looked at her doubtfully.

"It's nothing." Jiang Xiyu shook his head quickly: "Brother-in-law, eat it quickly. It won't taste good when it gets cold."

Su Yuchen said no more. After finishing the wontons, he stood up and said, "I'll go up and see Sister Yue."

"Um……"

Jiang Xiyu squeezed out a slightly stiff smile towards Su Yuchen: "Brother-in-law, I'll take care of it."

"Get some rest early." Su Yuchen said, got up and left the kitchen, heading towards the second floor.

After seeing him go upstairs, Jiang Xiyu stood up and sat where he had just been. He reached out and picked up the spoon, put it to the tip of his nose and smelled it. Then he stretched out his tongue and licked it gently: "My brother-in-law used it..."

She narrowed her cherry-colored eyes as if she was enjoying it. While her body was trembling slightly, she gradually clenched her hands and stared unblinkingly at the pink magic power that was gradually disappearing at the bottom of the bowl.

"Brother-in-law, I'm sorry. I didn't want to use this method, but... I really can't help it..."

Jiang Xiyu lowered his head and murmured: "You don't even want to take another look at me..."

With that said, she picked up the rice bowl and slowly walked to the sink, put the bowl in, and walked towards the second floor without any intention of cleaning it.

On the sofa, Xia Yushuang, holding the charming Xia Yushuang in her arms, saw Jiang Xiyu going upstairs and couldn't help but sigh: "They are all great actors."

"Uh-huh, meow~"

Rao Rao nodded in agreement: "It looks good, it looks so good!"

"Really?" Xia Yushuang chuckled: "The family ethics drama she acted was so good."

As she said that, she glanced at the camera that Jiang Xiyu had arranged in advance, lowered her head and said to Rao Rao: "You said that it is not a problem for our GC club to put on a stage play on the school's anniversary."

Rao Rao blinked: "What are you playing?"

"The sadomasochistic relationship between a junior and seven seniors." Xia Yushuang joked.

"Sadism is not good, meow~" Rao Rao disagreed very much. Where did the master and everyone abuse him?

Obviously so happy~

"Then the story of the harem?" Xia Yushuang pondered: "But it's not very good. What if others are too envious of Yuchen? And it is not a good thing for his current identity to be spread out."

"Do you really want to act?"

"Of course I'm joking." Xia Yushuang pinched her cheek: "Our life should not be shown to the outside world."

"Hmm, meow~"
