Jinwoo was on his way back from Daeho's house.
Right by the restroom in the park near his house, a group of high school girls, who looked like seniors, were hanging out.
Glancing over, he saw them nonchalantly smoking cigarettes in their school uniforms, a sight that looked quite out of the ordinary.
Jinwoo tried to pass by them quickly, hoping to slip through unnoticed.
But then, a familiar voice from the group called out to him.
"Hey! Jinwoo~!! Come here!!"
It turned out the voice belonged to Sohee.
Wearing bold makeup, Sohee was holding a lit cigarette in one hand. As she squatted down, her skirt had ridden up, refreshingly revealing her smooth thighs.
"Huh? Noona, what are you doing here? Are these your friends?"
Like a pet dog that had narrowly escaped the black market and been rescued by its owner, Jinwoo felt an inexplicable sense of relief and tried to act as friendly as possible.
"Hello, Jinwoo~"
Another soft and cozy voice called out.
"Huh? Sinbi noona? You're here too?"
Next to her was Sinbi noona, one of his sister's friends.
She was Sohee's best friend and the sister of the beautiful pervert, Shin Seulgi.
Normally, Jinwoo wouldn't have recognized her because of her unusual makeup and outfit.
Sinbi noona had a mysterious, somewhat exotic aura…
a beauty with a bob cut reaching just below her ears,
a small and sleek body,
and voluminous chest and hips.
She definitely had the full package of a woman.
Until middle school, she used to exercise with Sohee.
When Sohee stopped exercising, it seemed Sinbi noona had quit as well.
Each had their own reasons, but they were undoubtedly close.
-Sinbi noona was the one who had told Jinwoo why Sohee quit exercising-
Sinbi noona was wearing her school skirt folded up like a miniskirt.
Standing next to Sohee, her plump yet shapely thighs gave off a charm quite different from Sohee's.
"Hello~ You must be Sohee's brother, Jinwoo?"
"Oh my, just as handsome as I heard."
"Are you on your way back from school now?"
On either side of Sohee and Sinbi noona, there were three more girls he hadn't seen before.
All three gave off a bit of a bad-girl vibe, beauties who could easily hold their own alongside Sohee and Sinbi noona.
His sister's friends were also wearing short skirts and heavy, risqué makeup.
One of them had even unbuttoned her school blouse, intentionally revealing her bra.
Despite their tough appearances, their manner of speaking was entirely gentle and kind.
"Ah, yes, hello~ I'm Jinwoo, Sohee's brother."
Jinwoo bowed to the older girls he was meeting for the first time.
After greeting them, he turned his gaze to something that had been bothering him for a while:
The cigarette stuck between the index and middle fingers of Sohee's left hand.
"But Sohee noona, what are you doing? Smoking?"
Jinwoo was quite surprised to see Sohee smoking for the first time, but given the situation, he tried to keep his cool as he asked.
"Can't you see? Why are you asking? Wanna try one too?"
Sohee, perhaps trying to act tough in front of her friends, stood up, walked over, and offered Jinwoo the cigarette she was smoking.
"Ah, no thanks, I'm good~"
Jinwoo waved his hands and declined.
"Haha, how cute. Sohee is lucky to have such a brother. I'd be jealous if I had one too..."
The girl who had her blouse unbuttoned to show her underwear commented.
"What's the use? He hardly listens anyway! If you tell Mom about what you saw today, I'll kill you! Got it!?"
Sohee scolded Jinwoo in a threatening tone.
"I don't care, handle it yourself. I don't even want to bother."
Jinwoo, perhaps upset by Sohee's exaggerated attitude in front of her friends, snapped back.
"Did you hear me clearly, you?"
Sohee kept pressing, as if demanding confirmation.
"I said I got it!!"
Jinwoo replied, almost shouting, as if exasperated by her persistence.
"Ah right, Mom said she's going out with Minji today and will be home late,"
his sister suddenly remembered and told him.
"Mom and Minji? Where to?"
"Ask Mom about that later when she gets back. More importantly, we need to make dinner ourselves! I'll be home in about thirty minutes with Sinbi, so boil some ramen by then, got it?"
"I'm tired!! I'm going straight to bed, so you can cook for yourself."
Jinwoo, clearly not liking how his sister treated him in front of her friends, talked back with the rebellious spirit typical of a defiant teen.
"You really don't listen, do you? Then just piss off."
His sister snapped harshly.
"If you hadn't called me, I would have just left on my own."
Jinwoo resisted without backing down.
"He always talks back to his own sister. I'm not holding you back, so just piss off! Go home and crash or whatever!!!"
"I can't believe this~ Speak nicely! I'm leaving."
Their conversation ended, displaying the rough but strong bond typical of siblings, just as those around them might expect.
"Leaving already?"
"Stay and talk a bit more~"
"Ah, he must be sleepy. Take care, see you later~"
Sohee's friends expressed their regret at his departure.
"See you later, Jinwoo~~"
Sinbi noona gave Jinwoo a bitter smile, looking sorry and sympathetic.
Jinwoo bowed to the girls and headed home.
Upon arriving home, Jinwoo lay on his bed without changing his clothes and reflected on the events that had occurred earlier with Aunt Gyuri.
He had finally managed to smack Aunt Gyuri's ass today.
After sending a photo to Daeho, he had even received a message of thanks, and he was now looking forward to the open possibilities of his future with Aunt Gyuri.
He imagined pulling off Aunt Gyuri's skirt as she kneeled in a cat pose, relentlessly spanking her ass.
Smack
Smack
Thump
Following the sound of flesh being struck, intense moans filled the entrance hall.
"Aah~"
He put a red collar on her and tied her hands behind her back with a rope.
As he buried her face into the floor and hit her ass again, Jinwoo shouted, "Sohee, you fucking bitch!!!"
Slap!!!
'.....?'
After striking her, he realized something was off.
'Sohee?'
'Sohee?'
Jinwoo stared closely at the naked woman whose face was buried against the floor.
He felt an uncomfortable dissonance.
Suddenly, the naked woman turned her head toward him and shouted.
"Hey, Yu Jinwoo, are you going to untie me right now? I'm really going to kill you!?"
The woman tied up on the floor, with her hands bound behind her back, was Sohee.
Jinwoo felt his heart sink in shock.
"Ah! Sis, why are you down there like that!?"
"You're doing this? I'm going to tell Mom everything!! You'll be beaten to death and thrown out of the house!!!!"
Sohee, her eyes fiercely narrowed, yelled at him.
"Ahhh~~ Sis, it's not what it looks like! I'm sorry, please forgive me!"
Jinwoo reached out to grab his sister, but she was out of reach.
He waved his hands through the empty air.
"Ahhh~~~ Sis~~~"
Jinwoo screamed in his dream.
But in reality, all he could muster were muffled groans.
"Ugh~ ugh..."
"Jinwoo~ Jinwoo? Are you okay?"
Sinbi noona was waking Jinwoo up, speaking to him as he slowly came to his senses.
"What kind of dream were you having to make such weird noises? Wake up, Jinwoo, I made ramen~ Let's eat."
As Jinwoo opened his eyes, he saw Sinbi noona smiling angelically, her lips moving sweetly.
After such a bizarre dream, seeing her heavenly smile was a strange reminder of how mysterious life could be.
"Come on, wake up, Jinwoo. Noona made ramen, aren't you hungry?"
There was Sinbi noona, as gentle and uplifting as an angelic presence.
With his troubled mind somewhat settled, Jinwoo followed Sinbi noona down to the living room on the first floor.
On the first floor, Sohee was practicing a dance while watching an online video. She was working on the basic steps of b-boying.
Seeing Sohee so engrossed, Sinbi noona pursed her lips and gestured with her hand for quiet.
Then she exaggeratedly mouthed 'watch this' to Jinwoo and tiptoed toward Sohee from behind.
While Jinwoo watched, Sinbi noona counted with her fingers… one, two, three… and then she lifted Sohee's skirt.
"Ah! What are you doing!!!"
Startled, Sohee quickly pulled her skirt down and looked around to assess the situation.
Then, suddenly, she charged at Jinwoo and delivered a low kick.
"Why are you doing this to me? It wasn't me~"
Caught off guard, Jinwoo cried out at the injustice.
"You saw it!! Damn it!!!"
Sohee's rebuke was sharp.
Indeed, Jinwoo had seen it.
The sporty black panties, soaked with sweat, clinging to the nicely shaped ass of his sister.
And the letters "BS" spelled out in calligraphy, tattooed in black on the inside of her left thigh.
