A certain scientific Saten Ruiko

"Really~ Why would I do such a thing?" Misaka Mikoto complained while cleaning the swimming pool with a mop: "Although it is indeed too much, but this corresponding punishment..."

At this point, Misaka Mikoto finally couldn't bear it anymore and shouted up to the sky: "We are actually asked to clean this ridiculously big swimming pool. No matter how you look at it, it's hard for someone to do it!"

"Whoo~"

After yelling, Misaka Mikoto took a breath and muttered with a look of despair: "I've been working from early morning to early afternoon, but I haven't even finished 30% of the work. I don't know if I can finish it today!"

"Guhehehe~ Guhehehehe..."

Looking at Misaka Mikoto's shirt that became translucent because it was soaked in water, Shirai Kuroko's laughter gradually became abnormal!

"Suck it~"

He turned around and secretly wiped the saliva from the corner of his mouth and began to think to himself: "How lucky I am to be able to enjoy alone time with my sister who is soaked in sweat in the swimming pool!"

Of course Heizi would not just think about such a once-in-a-lifetime opportunity, but take action.

He walked to the swimming pool, opened his bag, took out a thermos cup and said to himself: "This is really a once-in-a-lifetime opportunity to avenge shame~"

"Onee-sama~"

"Huh? What's wrong?" Misaka Mikoto turned her head and asked in confusion when she heard the voice!

"When working under the scorching sun, it is necessary to replenish water~" Heizi took out the thermos cup and asked with a smile: "Would you like some of my special drinks?"

"no need!"

Misaka Mikoto decisively refused and continued cleaning the swimming pool!

Heizi smiled unanimously: "Why?"

Misaka Mikoto stopped what she was doing when she heard the question, turned her head slightly, looked at Kuroko with a scrutinizing gaze and asked, "Didn't you put the so-called computer accessories in there?"

Heizi was speechless and sweating profusely!

"As expected..."

Misaka Mikoto knew this would happen. She was a school girl whom she had known for a month. Although they had not known each other for too long and did not know each other too deeply, her perverted thoughts towards her were real and she needed to Always be on guard!

Seeing the other party's careless attitude, Misaka Mikoto knew that something was up with her, and as expected, the true purpose of this guy was revealed in just one sentence!

"Shirai-san!"

At this moment, a voice suddenly sounded and attracted the attention of the two people in the swimming pool!

I saw two girls wearing special Tokiwadai swimsuits standing at the edge of the pool at some point!

"As expected, it's Shirai-san!"

One of the girls with black hair asked with a smile: "What are you doing here?"

Shirai Kuroko turned around helplessly and replied: "As you can see, the swimming pool is being cleaned!"

"But why?" the girl with short curly brown hair asked curiously!

"Alas~" Shirai Kuroko sighed and said with emotion: "Even in early summer, it's hard to resist the coldness of the world!"

"But speaking of which, what are you doing here?"

"We are members of the swimming club..."

Misaka Mikoto turned around and looked at the two girls in swimsuits curiously and thought, "Are they Kuroko's classmates?"

"That is to say..."

He looked at their chests, then at his own, and sighed.

"You are younger than me..."

"sister!"

"Ugh?"

Misaka Mikoto looked up and saw Shirai Kuroko extending his hand to introduce to the two girls:

"They are my classmates Wanuchi Kinuho and Puff Wanbin!"

The two of them bent down slightly when Kuroko introduced them!

"good afternoon!"

Misaka Mikoto responded with a smile!

After introducing his classmates, Kuroko Shirai stretched out his hand to signal Misaka Mikoto to introduce to the two girls: "This is..."

"Um...excuse my presumption..."

However, before Kuroko could finish his words, he was interrupted by a cute girl with slightly curly brown hair.

Kinabaru Wanuchi looked at Misaka Mikoto and asked uncertainly: "Are you Misaka-senpai?"

"Huh? It's me..." Misaka Mikoto was slightly startled. Is she so famous? This new school girl actually knows me!

"It's true~" Wanuchi Jingbao showed a surprised expression.

"Do you still remember?" In the swimming pool, Wanuchi Kinubao put his hands together and looked at Misaka Mikoto with admiration, and said: "When I was surrounded by bad boys in Qianda, luckily you came to help me!"

"Ah~ there's that thing..."

After hearing this, Misaka Mikoto began to recall, but she couldn't remember it at all. After all, she would teach a group of bad boys almost every once in a while.

She has also saved girls who were surrounded by bad guys many times, and these things are just easy for her, and she doesn't care about these things at all!

"Thank you very much for what happened that day!" Wanuchi Jingbao said and bent down to thank you!

Puff Wanbin on the side also smiled and said: "I have admired his name for a long time, and it is really an honor to see his beautiful face with my own eyes!"

"As expected of you, onee-sama~ She is also punishing bad guys in places I don't know about~" Kuroko Shirai stood not far away with a proud smile on her face!

"I was really scared at that time!"

"That's right. As soon as the weather gets warmer, the pests will come out of their holes!"

"However, it really lives up to its name!"

"That's right, Misaka-senpai was really handsome that day!"

"Haha...it's nothing!"

This situation is...

But Kuroko Shirai soon realized something was wrong (referring to Kuroko’s own inner thoughts!)

Seeing the two classmates looking at onee-sama with admiration on their faces, and chatting happily with onee-sama, Kuroko suddenly had a sense of déjà vu in the dormitory that morning!

(I’m overly concerned, it’s just that what happened in the morning made me sensitive!)

Heizi shook his head crazily and thought: "How could you deliberately alienate Heizi!"

"It must be hard to work in this hot weather, right?" Puff Wanbin said, taking out a bottle of drink from his bag and passing it to Misaka Mikoto, smiling: "I happened to bring a sports drink, don't mind it. If so, please drink!"

"Ah, thank you, you're welcome!" Misaka Mikoto smiled and took the sports drink!

(Ah~)

Seeing this scene, Kuroko's ponytail began to stand up, but when she saw her sister actually drinking it, her hair straightened even more!

(What’s with this vastly different attitude?)

Kuroko Shirai turned her head and covered her face in disbelief. Speaking of which, I have been ignored many times before (referring to wearing sexy lingerie and posing in front of Misaka Mikoto!)

When trying to make amends and deepening the relationship, they also encountered a wall (referring to wanting to take a bath with Misaka Mikoto, but was thrown out of the bathroom by the embarrassed Misaka Mikoto because she was dishonest!)

(Is onee-sama really deliberately alienating me?)

Heizi squatted in the corner, shrouded in the shadow of despair, but suddenly thought of something and raised his head again with a confident expression.

(Kuroko, cheer up. If you lose your confidence, regain it. If you feel uneasy, expel it!)

(That’s right, the only advantage I have is that as long as I have the ability to move in space, there are countless opportunities to help onee-sama...)

Having regained his confidence, Kuroko stood up and turned around with a confident expression!

but……

Just when I turned around, I saw the silk guard in the bay using his power to control the water flow to clean the swimming pool!

Misaka Mikoto was still standing by and praised with a smile on her face: "It's amazing, it's getting clean before your eyes!"

"My ability is to control the water flow. Although I have to submit a regular inspection report to the teacher in advance. Can I help after that?"

"But……"

"This is just a small thank you gift for what happened that day!" Kinuyasu Wanuchi said with a smile that this was just a thank you gift to thank Misaka Mikoto for her help that day!

"Thank you, you helped me a lot!"

After hearing this, Misaka Mikoto no longer found it easy to refuse, so she agreed with a smile!

Wanuchi Jinbao responded with a smile: "It's great that you are happy."

"It's really amazing. It's so easy this way!"

"Thank you for the compliment!"

Shirai Kuroko fell into sadness again, and picked up the mop in despair and cleaned the swimming pool bit by bit!

"The sports drinks are here, please help yourself!" After saying this, Puff Wanbin waved his hands and left the swimming pool with Wannai Silu Bao!

After waving goodbye to the two of them, Misaka Mikoto smiled and said, "Oh, I feel like a really good kid, don't you think so Kuroko?"

"That's right..."

Misaka Mikoto was in a good mood and continued to say with a smile: "It's really a big help, maybe it won't even take ten minutes!"

"That's right..."

"Ah~ I really want to finish it quickly and then go eat ice cream!"

"That's right..."

Finally discovering Kuroko's abnormality, Misaka Mikoto turned around and looked at Kuroko's inexplicably depressed back and asked, "What is the Chinese dynasty that was born in the tenth century?"

"That's right..."

"What's wrong? I'm not energetic!" Misaka Mikoto asked with a smile!

"It's nothing, please don't worry about it!" Shirai Kuroko's tone gradually became aggrieved: "Anyway, I'm just an incompetent guy who can't even finish cleaning!"

"that……"

Misaka Mikoto listened to the other party's slightly crying voice and said with concern: "If you have anything on your mind..."

"no need!"

Heizi yelled, tears falling from the corners of his eyes and dripping on the ground.

"It's all my fault that I'm totally unworthy of my sister... I cause trouble... but I'm useless..."

"I...do not have the right to stay with onee-sama like this~wuwuwu~"

"What...what should I do?" Looking at Kuroko who was crying inexplicably and heartbroken, Misaka Mikoto looked at Kuroko speechlessly.

"It's too sudden, I can't keep up with the tune..."

……

"Speaking of which, I wonder if Misaka-senpai gave her anything?"

Uiharu, who was drinking afternoon tea with Shokuhou Misaki, suddenly thought of something and looked at Saten Ruiko!

"Hmm~ I think I should give it to you!"

Saten Ruiko seemed to have thought of something funny, and the corners of her mouth unconsciously raised a nice arc!

Thinking of what happened in the swimming pool in the anime, Saten Ruiko felt a little pity. She really wanted to see it with her own eyes.

But if I didn’t allow myself and Chuchun, I wouldn’t be able to get in there at all!

"I'm very concerned about Shirai-san's reaction~" Shiri Uiharu said with a smile: "Think about her interest in underwear..."

"What are you talking about?"

When Shokuhou Misaki heard the name Misaka Mikoto, she pricked up her ears and listened curiously, but in the end she couldn't help but asked curiously!

"Oh, Misaka-senpai is planning to give Shirai-san a gift to celebrate one month of knowing each other!"

Uiharu Shili explained, but immediately said a little funny: "I originally thought that Shirai-san would like cartoon underwear similar to ours, but I didn't expect that Shirai-san would be so mature, and I didn't know about the one given by Misaka-senpai. Will Shirai-san like the underwear?"

"It's all about the heart~"

Shokuhou Misaki became lazy again after understanding the situation. She had just eaten the dessert and now she had nothing else to ask for.

There were no surprises in her plan, but she is really grateful to Saten-san~

If Saten-san hadn’t cooperated with him and successfully managed to get rid of Junko, he might not have been able to eat the dessert~

……

"Heizi, do you remember what happened a month ago today?"

Misaka Mikoto's gentle voice sounded in Shirai Kuroko's ears!

"A month ago today?" Heizi stopped sobbing after hearing this!

"That's right"

Misaka Mikoto smiled and nodded as she recalled, "On the night when you moved into my dormitory, the dormitory master caught you and gave you a severe punishment, right?"

"So, the next day, we were punished to clean the canteen..."

“Unknowingly, we got here together today!”

"As for the anniversary that belongs to both of us..." Misaka Mikoto said as she took out a wrapped gift bag from her bag and said with a smile: "Isn't it today? How could I forget it? ?”

Kuroko's mood improved, and he slowly walked over and took the gift bag and looked at Misaka Mikoto expectantly: "But... can you open it now?"

"of course can!"

Shirai Kuroko opened the gift bag and took the cute cartoon underwear in her hands to look at it!

Then I was so moved that I held this underwear in my arms!

Misaka Mikoto walked up with a smile and said in a gentle tone: "We will always be together in the future~ Please take care of me."

"Sister...Sister-sama, you just said...we have always been together..." Shirai Kuroko's thoughts turned into a strange corner again!

"Of course!"

Misaka Mikoto didn't notice this, picked up the two bottles of water placed by the swimming pool, gave Kuroko's bottle to Kuroko and said with a smile: "We study in the same school, live in the same dormitory, each other. Inseparable partners?"

"Come!"

"Cheers to partnership!"

"To the red line of fate between us, cheers~"

"Gudu~Gudu~"

"Ah~ let's keep working hard!" Misaka Mikoto picked up the mop and continued cleaning the swimming pool with full energy!

However, Heizi did feel that something was wrong with her body at this time. She felt that her whole body was getting hot and her mouth started to get dry!

He glanced at the water glass in his hand!

"Pfft~"

"Onee-sama~"

"What's wrong?" Misaka Mikoto turned her head and soon the corner of her mouth twitched!

I saw Heizi sitting on the edge of the swimming pool with a very enchanting movement at this time, looking at him shyly!

“Since we are cleaning the swimming pool, it would be perfect to wear a swimsuit that doesn’t hurt if it gets wet~”

"Um, no need, and it's quite troublesome to go back and get it." Misaka Mikoto rejected the proposal with a speechless expression!

"Hmph~ Actually, I had expected this to happen!"

"Jiangjiang~ I brought onee-sama's school swimsuit~" Kuroko Shirai took out a black one-piece swimsuit like a treasure!

"boom!"

The next moment, a mop hit Kuroko's face, and Misaka Mikoto angrily said, "I remember that it was placed in a locked cabinet!"

"Ahem, cough, cough...a mere lock is nothing in front of my abilities!" The mop on Kuroko's face gradually fell off, and Kuroko looked at Misaka Mikoto again and said with a smile: "Come on, please enjoy~ "

Then without waiting for Misaka Mikoto to react, she disappeared from the spot in an instant, and then appeared behind Misaka Mikoto with stars in her eyes, and put her two hands into Misaka Mikoto's top and skirt respectively!

"What...what..."

Misaka Mikoto felt empty for a while, and she immediately covered her skirt and breasts with a look of shame and anger!

Kuroko, on the other hand, looked at the underwear in his hands helplessly and complained to Pangji: "Onee-sama is really...wearing such childish underwear again..."

"Hey, give it back to me!" Misaka Mikoto covered her skirt and shouted in shame and anger!

"Then put on your swimsuit..."

When Shirai Kuroko said this, he suddenly discovered the highlight of Misaka Mikoto Fatji. He carefully compared it with the underwear given to him, his eyes lit up, and then he started to dance.

"It's a complete set, it's a complete set, it's a complete set, it's a complete set, it's a complete set with my sister~"

Misaka Mikoto's face turned red to the point of bleeding, and finally she couldn't bear it any longer and roared in anger.

"Kuroko!"

"It seems lively~"

"Misaka-senpai, the regular inspection is completed, I'm here to help..."

Before they finished speaking, the expressions of Wannai Siluho and Puff Wanbin instantly became dull, then became shocked, and finally turned red.

I saw Misaka Mikoto covering her skirt and breasts with a look of embarrassment, and her body was emitting beeping electric light!

"Ounei loves whipping~~oh~"

Kuroko Shirai was lying on the ground with a strange knowledge, her face flushed and she was letting out a series of imaginary moans~

"Stop talking and give it back to me quickly!"

"I don't want it~ ah~ oh~ ah~"

Wanuchi Kinubao: "Just pretend you didn't see it!"

Puff Wanbin: "Say...that's right!"

The two of them turned their heads and walked back at the same time, and smoothly closed the door to the swimming pool!

"Kuroko will never be discouraged again... I will always be by your side, onee-sama~"

"Give it back to me~"

"Bilibili…"

"what!"
