It's always hard to focus on writing when your mind is disturbed, so Chitanda doesn't demand a high level of standards, and simply records trivial fragments and inspirations.

In this state, although he didn't deliberately pay attention to Liumi-chan's every move, it was easy for the little guy to notice anything about it, intentionally or unintentionally.

After a while, he noticed that Rumi was holding up her cheeks, and her slender fingers were fiddling with the barrel of the pen, looking bored.

Chitanda was helpless: "Rumi-chan, concentrate." ”

Rumi frowned slightly, simply put down the pen tube, pouted and complained: "Because homework is boring, why do you have to write homework after school." ”

Chitanda Chengyu laughed, pondered for a moment and said: "Because you don't know if others will write homework when they go home, or that writing homework is the best choice for staying in the United States." ”

"What does that mean?"

"The derivation of the law of the dark forest plus the theory of the prisoner's dilemma is complicated to explain. In short, when Rumi-chan withers like a cherry blossom, there is no need to study. ”

"Withered like cherry blossoms?" Rumi Korumi showed a yearning look, "When was that...... I want to wither quickly. ”

"Poof......" Chitanda couldn't help laughing for a while, and finally rolled his eyes at Rumi, "Study with peace of mind, Rumi-chan hasn't bloomed yet!" ”

"Ha, Chitanda looks good when he rolls his eyes......" Rumi inadvertently sighed a little, and then turned her gaze to the book in frustration, still muttering in her mouth: "If you just study, your brain will become stupid......"

The stunned Chitanda Chengyu only felt that his entire brain was chaotic, but he had already dealt with Liumei and did not need to continue to persuade him.

He patted his face, let the burning lolicon soul cool down, and turned back to his work, but he didn't expect that it would be less than five minutes, and he heard Rumi-chan's call again.

"Sentanda."

Chitanda Chengyu was helpless and lamented: "What's wrong with Rumi-chan? ”

Rumi glared at him lightly, "There is a math problem that doesn't work." ”

"Hmm...... This is the right thing to do. ”

"It was."

Qianantitian Chengyu got up and walked over, teaching a primary school math problem, and no one would run away from it.

Sitting down next to Rumi, Chitanda slowly sniffed a sweet girl's fragrance at the table. Subjective or objective, Rumi-chan's bacteria are much better than those of Hachiman.

After the plain white pen barrel happily spun around Rumi's fingertips, it was picked up by Sentanda Chengyu.

"Which way?"

"That's it."

The slender fingers pushed the question book in front of Chitanda's eyes, and with pink nails, he scratched a question on the upper part of the open page of the question book.

Chitanda looked forward and leaned in, and when he approached the question book, he also approached Rumi's face, and the soothing snort and refreshing fragrance made him a little uncontrollable.

Qian Yan Tian Chengyu had no choice but to pick up the question book with his hand, looked back, sat up straight and looked serious.

Rumi's head tilted to the side very obediently, and her eyes took off the book in front of the desk, and instead looked around the room.

Chitanda Chengyu sat behind her and shook her head helplessly, but it was precisely because she was behind her that she found her slightly stiff breasts from a casual angle that she could see from the neckline of Rumi-chan's clothes.

It's obviously a chest that has just grown for a short time, but it's bulging in vain, and it looks quite seductive. Even Rumi-chan's petite body occasionally moves, and you can almost see the entire small breasts.

This made Qianantitian Chengyu swallow a few mouthfuls of water quietly, and the rise in some places hardened disobediently.

However, Qianantitian Chengyu didn't dare to think too much, and forced himself to put his mind on the math problem. He knows very well that little Lori is not easy to provoke at all.

Regardless of whether you are completely sure or not, you still obediently pick up the eldest dick...... Wrong...... It should be said that it is good to clamp the big tail.

"Ahem, the formula for adding the fractions should be factored, no, it should be said that the splitting method should be used."

"Huh?"

Rumi-chan's eyes were confused, her big beautiful eyes blinked gently, and Chitanda Narita unceremoniously flicked on her smooth head.

"Listen carefully~~"

Rumi-chan covered her forehead with tears in her eyes, "Hmm~ I know." ”

Qiantantian Chengyu said it again in more detail, this time Rumi-chan listened quite seriously, and naturally quickly understood.

She turned her head, and her thin pink lips spit out a small moist tongue at Chitanda Chengyu, making a cute grimace.

Then she lay down on the table and wrote the question book, even her little buttocks were cocked, and the evil safety pants under the skirt of the pleated short skirt swayed back and forth casually in front of Chitanda Chengyu's eyes.

However, safety pants are not safe, but Rumi's thin waist and slightly elastic buttocks will easily remind people of thinking of entering from the back.

Wait, why do you feel like you're being impulsive again!

Chitanda pouted disdainfully to himself, and reluctantly forced himself to look away.

Even so, he couldn't help but sigh in his heart that Rumi-chan was really gradually becoming a delicate and seductive beautiful girl.

"Chitanda, is this right?"

Xiao Rumi put down the pen in her hand, and while taking the question book to Chitanda, she actually leaned over her immature body.

The round and sexy little ass had just disappeared from view, and the long, fragrant black hair was already dangling in front of Sentanda Narita's nose.

Chitanda was in a hurry to change his sitting posture, and finally took the question book without revealing any flaws, and nodded to Rumi after reading it: "Well, that's fine." Still have questions? If you don't have one, just keep doing it. ”

"Ah~"

Hearing Chitanda Chengyu's words, Rumi-chan stretched out her arms and lay on the table, letting out a sad scream, but from Chitanda's point of view, the visual sense of her tender breasts pressing against the hard table was really tempting.

Obviously, Xiaoliumei is only ten years old, and she hasn't developed for long.

"Hurry up~"

"Chitanda, I don't want to move anymore."

"Come on~"

“あああああ……”

dragged a long tail note, Rumi-chan actually sprinkled coquettishly, and Qianantitian Chengyu couldn't cry or laugh, "I have to forget the cold appearance of Rumi-chan when we met for the first time." ”

Xiao Rumi's pretty face was suddenly dyed crimson, and she made a cute voice after the shame exploded, "Ahhhh

Reaching out and touching Rumi-chan's long straight black hair, Chitanda Chengyu was helpless, "Okay, okay, let's go have dinner!" ”

"Really?"

"Really."

Probably if you don't stop this terrible plot, Sentanda Chengyu may really be able to hurt the cute Rumi-chan!
