As for classmates and friends, I have never seen them around my sister, and my sister has never brought friends home to play with.

At this moment, he suddenly saw a girl acting so close to his sister, which made him feel quite happy.

"Idiot! Don't go crazy here!"

Nanako caught a glimpse of her brother's half-smiling expression out of the corner of her eye, and felt a little embarrassed.

He directly raised his hand and clasped Mizuki Eri's wrist, and then twisted it slightly. Mizuki Eri half-bent and shouted like a criminal arrested by the police:

"It hurts, it hurts... I don't want to play anymore, Nanako-sama, please let me go!"

"Who are you playing with, you idiot Mizuki! If you do this again next time, I will twist your hand and swell it!" Nanako frowned and said fiercely.

"Um?!"

When Nakano Mayu heard this sentence, he spoke with an accent and glanced at his sister.

No matter what, you can't just twist and swell your classmate's hand, right?!

"Ahem..." Nanako coughed twice when she heard her brother's accent, and said in a gentle tone: "Next time if you do this again, I will be angry..."

"..."

"Yes, yes, Nanako-sama, I know I was wrong..."

"Humph!" Nanako snorted coldly and let go of the girl's wrist.

"Ah, I am so happy to be treated so roughly by Nanako-sama so early in the morning~"

The girl Mizuki held her hands in front of the bear, making an intoxicated expression that was very inconsistent with the style of a sports girl like her.

When Nakano Mayu saw this, he looked at his sister with some sympathy.

Originally, he thought that the little yellow-haired dog next to him had a weird enough personality.

Didn’t you expect that your sister’s friends also have such weird personalities?

No wonder my sister never brought friends home again, just like she didn't really want to bring that wretched guy Yamada home.

"Who is this?" After the girl Mizuki was intoxicated, she saw a handsome young man with a handsome face and a tall figure standing next to Nanako. She quickly looked at Nanako and asked:

"Boyfriend-san?"

"Eh?" When Nanako, who was still angry at first, heard this, the anger on her face instantly subsided, leaving only a look of surprise: "Does he look like a boyfriend?"

"Are you really your boyfriend?!" Mizuki girl's eyes widened in an instant, she raised her hand to cover her open mouth (`o??), with a look of shock on her face as if she had seen an alien tentacle monster.

!

"Hey hey hey..."

Nanako smiled shyly and looked at her brother covertly.

"Boom--"

Nakano Mayu's lightning sword came unexpectedly and hit the same spot.

"Woo..."

Taking advantage of the gap between Nanako's hands covering her forehead, he took a step forward, nodded to the sports girl and said with a smile:

"Hello, is this Mizuki-chan? I'm Nanako's brother, Nakano Mayu..."

"Oh~~ It turns out you are my brother?!"

The sports girl's eyes sparkled, as if she had seen some high-end toy that she had never played with before. She looked excited, and then she quickly turned away and said shyly: "Eri Mizuki, I am Nanako-sama's classmate and best friend.

!!”

"Onii-sama, you can just call me Eri, I don't mind~"

"Hui..." Nakano Mayu hesitated.

It would be too weird to call the little sister I just met by her first name.

Even if she is Nanako's good friend, this is not appropriate.

But the other party asked again, and his face looked very expectant.

"How can you just call me by name, you idiot Mizuki!"

Nanako was rubbing her forehead that had been hit by her brother when she suddenly heard the idiot's request. She immediately bared her two gleaming little tiger teeth and said fiercely to Mizuki Eri.

"Ah? Nanako-sama is...jealous?"

Mizuki Eri's eyes swept over the two of them, with an expression on her face that she had discovered a new world. Then she directly raised her hand and walked forward and whispered to Nanako in a low voice: "Nanako-sama, are you the brother-controller?"

Hearing this, Nakano Mayu felt a little embarrassed, but his face remained calm.

After all, he felt that although he could not compare with that little maid, he could still do better than Qiansha in terms of the ability to keep emotions in check.

"Stupid...idiot..." Nanako heard Mizuki Eri's 'quiet' whisper, her pretty face turned slightly rosy, she peeked at her brother who was looking away as if nothing had happened, and whispered: "Don't, don't do it in front of your brother-sama."

Say this, otherwise I will be really angry!"

"Yes, yes... Nanako-sama, whatever you say is whatever you say..."

Mizuki Eri had a proud look on her face like a little fox who had stolen a chicken. She turned to look at Nakano Mayu and said, "Onii-sama will come to our class for the summer festival in a few days. Eri will wear a low bear maid outfit then.

Specially designed to give my brother the ultimate one-on-one enjoyment..."

After the girl finished speaking, she blinked and naturally straightened the little panda under her uniform shirt.

Nakano Mayu looked stunned, and his eyes followed him subconsciously.

Only then did I notice that this junior high school athletic girl seemed to weigh more than twice as much as her younger sister!

If you compare it with the girls around him, they are probably on the same level as Riho-chan!

For middle school students, a panda of this size can almost stand out from the crowd!

"Idiot...class is about to start, let's go!"

Nanako bit her lip, looking at her friend's "shameless" actions and hints, and angrily took her hand and ran directly to the school, as if she didn't want her brother to have too much contact with this "outgoing" little girl.

touch.

"Nini, let's leave first..."

"Eh? I want to talk more with Onii-sama~~"

Mizuki Eri, who was pulled forward by Nanako, turned to look at Nakano Mayu with a teasing expression, and blinked her big black eyes.

Then she suddenly lifted up the skirt behind her slightly, revealing her milky-white skinned thighs that were different from the wheat-colored skin of her calves. At the same time, there was a trace of dark fabric looming inside the skirt.
