Stupid little sister

"Rin-chan, good morning."

Yuika quickly stood up with a sweet smile on her face.

Wait.

Do not panic.

The more panicked you are at the moment, the easier it is to make people suspicious.

"The final exam is coming soon, I was a little worried about failing the exam, so I asked senpai to help me with my homework."

Even though Yuika didn't panic, she quickly found an excuse.

To prepare for the exam, it's normal for juniors to come to senior's house to study, right?

Rin tilted her head and asked for no reason:

"Yuika-chan came to ask Nii-chan for tutoring, why don't you come with me?"

"That, that…" Yuika's eyes flickered, "Because the weather is too hot, I feel like coming out will melt on the way, I don't know if Rin-chan will come out."

"Of course." Rin raised her pitiful little chest, and said. "Only Yuika-chan is my best friend, let alone going out together in the summer, even if it's going up the volcano is fine!"

"Rin-chan."

Yuika turned her head pitifully, her conscience inadvertently taking a critical hit.

"Yuika-chan, why are you crying?"

"It's okay, my eyes accidentally got into the sand."

"Will there be sand in the room too?"

"Of course there is." Naoki said lightly, "Do you know why the floor in the house is often dusty, because there is a lot of invisible dust in the air, and skin flakes from human bodies..."

"Stupid Nii-chan!" Rin clenched her fist and hit Naoki's stomach "Don't talk about such strange knowledge in front of girls!"

Naoki stretched out his right hand and held Rin's fist with his palm.

"You actually blocked my stand attack?" Rin's eyes lit up, she jumped back half a step, and shouted, "Take my move, King Flame, Black Dragon Wave—"

Naoki said in surprise:

"When did you read Battle Through the Heavens?"

"I haven't seen it." Rin raised her chin, "I just saw someone on the Internet say that this move is the most powerful and passionate. Nii-chan, take this!"

This is definitely a list of the most embarrassing moves! To be able to scream loudly in front of classmates, you don't want face, I want it!

"Don't come near me." Naoki said coldly, "I'm sweating."

"Nii-chan really doesn't like me?" Rin screams sadly, "Obviously you've slept with me before… Sure enough, once a guy gets a girl's body, he'll never appreciate it again."

"Hah?"

Yuika was dumbfounded when she heard those words, the smile on her face suddenly stiffened, and she looked at Naoki with wide eyes, "Senpai, Rin is your little sister, even if you are not blood related, you can't start, you will lose your qualification to become human!"

"It was a thunderstorm earlier, and just in time for my parents' business trip, Rin insisted on sleeping with me."

Naoki hadn't done anything wrong, so he didn't panic at all.

Rin sniffed: "But when I woke up the next morning, the buttons of her pajamas were all unbuttoned by Nii-chan…"

"Button?"

Yuika looked up with a glaring face, "Senpai, please explain to Yuika."

Naoki sighed: "I was kicked out of bed by you in the middle of the night, and your pajama buttons were unbuttoned. What does that have to do with me?"

Yuika: "😐"

"There's ice cream in the fridge." Naoki waved his hand disdainfully "Give you three seconds, if you don't eat it, it will be gone."

"Uh, ice cream?"

Rin's eyes lit up, turned around and ran into the house, forgetting the move instantly

"Wow, that's a lot." Rin opened the fridge and exclaimed quickly, "There's so much stuff in the fridge, shouldn't Nii-chan be robbing a cold drink shop?"

"So after all, stupid robber, she will rob a place like a cold drink shop." Naoki could only complain, "Do you think everyone is as stupid as you?"

Rin took a piece of ice cream for granted, and didn't forget to say hello to her friend: "Yuika-chan, come and have some ice cream."

"You eat it." Yuika shook her head, "I just ate it."

"Then eat something else." Rin said happily, "A summer without ice cream is not a complete summer."

Luckily, Rin didn't forget Naoki, so she handed her another ice cream, "Let's eat with Nii-chan."

After eating the ice cream, Naoki looked at Rin who was sitting in front of the electric fan with his mouth open and whimpered: "What are you doing here on such a hot day?"

"Of course I came to play with Nii-chan." Rin stretched out her hand to lift the collar of his shirt and let the wind blow in. "It's boring being home alone."

"Then you won't be bored now." Naoki patted the exercise book in front of Rin, "Let's study."

"I don't want to." Rin suddenly slumped "I want to play a game, but mom won't let me play at home."

Naoki said casually:

"Playing games will interfere with Yuika's studies, are you sure you want to play?"

"Eh?"

Yuika looked at him in surprise, and a blush quickly appeared on her face.

Only a close enough relationship would call her by his first name... Did the servant already recognize herself as a master?

"Forget it… let's study together."

Between the game and his friends, Rin struggled for a few seconds and quickly made a choice.

...

It was noon.

Naoki went out in the sun, went to the supermarket downstairs to buy ingredients, then walked to the kitchen to prepare lunch.

"Servant." Yuika walked over and whispered, "Can I help you?"

Naoki looked down and saw slender legs wrapped in white silk: "No bench..."

"Stupid servant!" Yuika suddenly became angry, rolled up her sleeves and walked over, "Yuika doesn't need to step on the bench, so I'll show you now!"

"Are you sure it's okay?"

"Of course not, but Yuika doesn't seem to be cooking at home."

"It doesn't matter." Naoki stepped aside, "You did it."

Yuika stretched out her small hand: "apron."

"Yes."

Naoki took out an apron from the cupboard and handed it over.

"Look at me." Yuika put on her apron and averted her gaze, "Servant, chop the onion."

"Accept."

It is very easy to cry when cutting onions, soak the knife in cold water before cutting, which can effectively avoid the evaporation of irritating substances.

Naoki wasn't a novice, so of course he wouldn't be fooled, and he'd be chopping onions quickly.

"The servant is actually ready." Yuika's dog looked on in surprise, and slightly regretted, "Cut the potatoes together."

The prep work was done, and Yuika quickly took over and started cooking.

Naoki stood and watched, and was surprised to find that Yuika wasn't lying, beyond the reach of culinary novices.

It's just that she's a bit short, and she has to tiptoe while cooking, which makes Naoki always want to place a stool for her.
