Reviewing in the library is much more attentive than at home.

As for the reason, it is also very simple, because at home, there are always some force majeure around you to distract you.

For example, I have a computer next to me, a PS3 in a small cabinet on the desk, a PSP and PSV handheld on the bed, and adult comics stuffed under the bed.

In the dead of night, out of boys' instincts, I either secretly read adult manga for a while, or play 3DH beautiful girl games for a while.

There are very few homework in the International Department, and I do it at the end of the assignment once a week, and the time for revision is even more unplanned.

After spending half a semester in such a mess, I ushered in my midterm exams.

Alas, it's hard to make up, and I don't know if it's useful to work hard before the exam.

But isn't there a saying that says: grinding the gun in battle, it's not fast and light, so I asked my sister to help me review.

My proud beautiful girl Xueba sister got the second place in the last 60-person exam in the International Department, and it was absolutely no problem for her to tutor.

"Knock..... Boom"

A little after dinner, I went out of my room and knocked on my sister's door next door.

"Ling, your brother came to you for a review."

I said, coughing lightly at the same time.

"Huh? .... That one.... Wait a minute......"

When my sister heard my voice, she seemed to be flustered for a moment, a little panicked, and then she stumbled and stumbled about something.

It was as if I heard the sound of her tidying up the room, the sound of zipping up her clothes, and the sound of getting dressed......

Hey, there's no need to bother so much if my brother comes.

Don't.... My sister is the same as me!?

I had a very terrifying guess in my heart, even I didn't dare to think about it: maybe, Ling was taken by me, and at this time he was also playing adult games or watching adult comics or something....

！

Well, no.

My mind gradually came up with the appearance of Ling watching adult anime, no, I can't imagine it at all!

"Alright."

Just as I was thinking about it, Ling opened the door.

Her pretty face was slightly red, she rarely lowered her double ponytails, her long straight black hair reached her waist, and she wore a light blue dress.

"Ling ..... You've been in there for five minutes....."

I looked at my lovely sister and said with some concern, still thinking that she had been taught by me to play adult games.

"I've prepared a little...."

She blushed and said, no, although it is a little difficult to speak, but it is better to remind my sister.

"Ling.... Listen to me....."

I closed the door like a brother and put my hand on her little shoulder.

"Uh-huh....."

Her face instantly turned even redder, as if someone had poured red paint from top to bottom, red to the base of her neck.

"Brother..... I have always regretted that I embarked on the road of no return to play adult games in my room...... I don't want you to do that...."

I looked at her solemnly and said like a qualified brother.

“......”

The two were stunned for a moment.

"You think I took the time to prepare because I played adult games?"

She asked me in a trembling voice, clenching her pink fist and bowing her head.

"Uh.... I guess so. ”

I said embarrassedly, ahhh

"Boom-"

Ling stomped on me hard, and then looked up at me angrily like a lion cub, blushing with a hint of dissatisfaction in his eyes.

"Perverted..... I won't be as corrupt as you..."

"Uh, isn't it?"

"It's a change of clothes! I just tidied up my room and changed my clothes! ”

Ling said dissatisfiedly, it turned out... Is this the truth!?

It's over.,I've become a scumbag brother who plays adult games by myself and misunderstands my sister!

"I'm sorry!"

I bow sincerely and apologize—please spare me, Princess!

“..... Hmph, I didn't expect you to think of something pure—[Mating Maniac]..."

My sister complained, uh, have I upgraded from [Mating Paramecium] to [Mating Maniac]! Although it feels handsome to change from a single-celled animal to a demon, isn't it even more lost!

"Apologies again... It's me who lives the belly of a gentleman with the heart of a villain....."

I scratched my head and said, saying that every time I came to Ling's room, she would be so grand, and she also changed her clothes.

I remember last semester, when my cousin Yahuo and Yu You came to play with me, I was accidentally seen by them when I went out of the bath, and after Ling knew about it, Ling called me to the room and wrote a letter of guarantee, and at that time, Ling seemed to be wearing a very gorgeous princess dress.

This time, it's no exception, although it's a little more elegant, but it still feels like a dance party.

"Look at what I'm doing... Perverted. ”

She noticed my gaze and sneered dissatisfiedly.

"Uh... I just think this outfit suits you well. ”

I said.

"Hmm..... Oh, that's good..... Wrong... God, you're not here to talk about this, but you'd better review it....."

She raised her eyes to me with a red face and said, hammering me with her pink fist.

That's right.... I came to my sister's room to study, so I have to study hard!

I glanced at my sister's room, and for some reason, at this time, I felt a little heartbeat.

The body fragrance that belongs to the beautiful girl wafts in the air of the room, the princess room in the style of the British royal family, the elegant bed - velvet covers the bedside, the gorgeous and delicate hanging lamp, and the silver curtains with a slight purple pattern......

It's my sister's room, but it's also a girl's room - it's the room of the most beautiful girl in the international department!

Shen Ling, the first beautiful girl in the international department, is one hundred and fifty-five centimeters tall, petite and cute, with double ponytails to the waist, and has the appearance of an anime beautiful girl, as well as a unique temperament like a princess.

At this time, such a beautiful girl was alone with me and tutored me in my studies.

It's a pity that she's also my twin sister who I can't knock down.

Pushing down my cousin actually has a solution, it's a big deal to flee to the United States....... But if you overthrow your own sister, you can say that you are the enemy of the whole world and the world.

Alas.

After such a small sigh in my heart, I regained my senses, and Ling and I can only be brothers and sisters for the rest of our lives, isn't this a predestined thing?

"Well, let's start studying, Ling."

I said to her, don't think too much, Ji Shen, think about the exam in front of you!

"I know.... Let's get started. ”

My sister said with a slight blush, and then stopped, as if to say something to me.

“....”

I looked at her with some confusion, why didn't she speak?

"God.... Let's. ”

My tutor, the super invincible and cute beautiful girl sister Shen Ling, bowed her head to me with a blushing face.
