Fucking the S-Class Noona and Her Friends
Lee Do-jin returned home after finishing his long life at the Academy.
'Finally going home.'
Around age 12, due to the results of the annual health check-up at school, he was diagnosed as a Hunter, and Lee Do-jin had to receive early education.
9 years since he left home at a young age and lived in a full boarding school Academy.
Normally, Hunters would immediately join a guild and continue their Hunter life, but Lee Do-jin didn't need to.
Because his noona, who is 7 years older, had amassed a huge fortune from her long Hunter career.
[Seo-ha: Arrived in Seoul?]
[Do-jin: Yeah]
[Seo-ha: Sorry I couldn't pick you up, I'll come home early. Wait at the house.]

In the photo, familiar faces were seen with noona.
Noona's friends whom I often saw during holidays or Academy events.
S-Class Hunter, Lee Seo-ha.
S-Class Hunter, Ryu A-rin.
S-Class Hunter, Song Su-a.
'... They got prettier.'
@
The giant tower that rose from the site where Gyeongbokgung Palace once stood,
Lee Seo-ha was an S-Class Hunter who was making great contributions in that tower.
For her, securing a detached house with a yard near Gyeongbokgung, where parking space was scarce... wasn't that difficult.
'... No one's home, right.'
Noona had been living together with friends she grew up with since her F-Class days. In short, from now on, he would be living not just with noona, but also with noona's friends.
'... Ugh, living together with noonas from now on.'
Lee Do-jin was also a man in his prime.
It wasn't that he didn't know what it meant to live with adult women.
But this time, the noonas proposed it first.
[Seo-ha: What are you planning to do after graduation?]
[A-rin: Don't go hunting. With us and your noona around, why bother making money?]
[Su-a: Live as you please.]
[Seo-ha: Do you want to live with the noonas? There's plenty of extra rooms anyway, and I want to see my dongsaeng's face often... You guys are okay with it, right?]
[A-rin: Wait, hold on... Your dongsaeng is a guy too. What if we jump him? I can't resist that@@@]
[Su-a: Eh, I think it'll be fine... If it's Do-jin... no worries♡]
[Seo-ha: You guys just try to lay a hand on my dongsaeng.]
[A-rin: You're not even blood related, and you're the one setting the stage to fucking devour him.]
[Su-a: Are we all going to lose our virginity soon? Do-jin is a virgin, right♡?]
... And so, Lee Do-jin ended up living with them.
In fact, he could have refused, but he didn't really want to, so he agreed.
'My room....'
He checked the room. They said they'd give him a spare room, but it seemed they gave him the biggest one.
The bed was unnecessarily large, and it had an attached bathroom.
'First, take a shower... and unpack?'
There were two types of boxes.
Those from the Academy dormitory, and those left behind at the old house before entering the Academy.
Organizing the dormitory stuff was quick. But the old stuff was ambiguous.
Clothes that didn't fit were thrown away long ago; most were sentimental items.
It would be a waste to throw them away, but if kept, they'd just be buried in storage.
'... Is this a diary?'
A 500 won notebook, a child's diary with grids for neat handwriting.
He couldn't remember his childhood now, so he carefully opened it.
[Year XX Month XX Day]
When I said I had a school picnic, noona made delicious kimbap for me!
I said I wanted to eat it every day, but she said to ask for it when I get a girlfriend!
So I said I'd make noona my girlfriend!
[Year XX Month XX Day]
Lately, whenever I see noona, I get a strange feeling!
Seeing her after she comes out of the shower, my penis keeps getting bigger and bigger!
I kept touching it and felt strange, but noona saw it and scolded me, saying I shouldn't do that.
Hmph.
[Year XX Month XX Day]
I felt strange when I saw noona who overslept in the morning.
While looking at her, I did what felt good last time and ended up involuntarily shooting out white urine.
I got scolded badly by noona when she woke up.
They say you should do this to a woman you want to marry, so can't I marry noona?
[Year XX Month XX Day]
In the middle of the night, I heard a strange sound from noona's room.
It felt like she was crying in pain... At first I thought it was a ghost.
Why is she shaking her waist on the pillowcase? Is she practicing horseback riding?
As I kept watching, her butt turned toward me... (erased)
'Uh, oh?'
I think I might have done this before...
Embarrassed by the content, he couldn't read anymore and closed it.
'E-everyone does that, right. If you're a younger brother with a noona, everyone... has this kind of past.'
Marrying noona.
... Lee Do-jin and Lee Seo-ha were not blood related.
He learned this after entering the Academy—during the corporate war, she took in the child of a fallen comrade, and that was him.
On the family register, they were family, but genetically, it was a relationship with no issues.
'Ugh....'
Because of that, Lee Do-jin actually saw Lee Seo-ha as a woman.
Though they spent childhood together, during his actual growth into a man, he lived in the Academy dormitory, growing up as strangers.
During holidays or vacations, whenever he went out for field training as a Hunter... he thought.
'Such a pretty woman is my noona....'
What does noona think of me?
She must have no thoughts about it, so she called her non-blood related dongsaeng to her house.
Or maybe, noona also....
@
Late at night, long after dinner time, the noonas finally returned.
"... My dongsaeng! Congratulations on graduating!"
Lee Seo-ha came in one stride and hugged him, black hair and black eyes, sharp gaze, legs trained like a track athlete... famous for her leg lines that seemed ready to burst her pants.
In fact, Lee Seo-ha's abilities were deeply related to running.
People say her personality is decisive. But Lee Seo-ha became gentle and soft only when she saw her younger brother.
Honestly, Lee Do-jin didn't understand the harsh evaluations of his noona.
Because she was endlessly kind to him.
"Noona, you got prettier."
"Ehehe, pretty? That's a relief."
"She went to the salon days before you came, got skin treatments she never did, it was no joke."
The woman who approached next was Ryu A-rin, one of the friends who always hung out with noona.
Ryu A-rin had blonde hair and a voluptuous chest, and her hobby was cosplay... sometimes, when she came to see me at the Academy, my peers would clamor for her autograph.
In Lee Do-jin's personal opinion, the photos of Ryu A-rin circulating on the internet were not great.
Because she was prettier in person.
"A-rin noona, you've been well?"
"Me? I've been good. You... look taller. Heung♡"
Ryu A-rin gave a sly smile and whispered in front of everyone.
"... Did you think about that thing from last time?"
"Ah, that... Well, I'll have some free time for a while, so."
"Good♡ No backing out later, okay?"
I never definitively said I'd do it.
Well, I guess it doesn't matter.
Then Song Su-a adjusted her glasses and spoke.
"What kind of promise are you two making? You were whispering so much..."
"It's nothing much... I watched the movie that Su-a-ssi recommended last time, it was good."
"Ah...♡ The sequel came out too, since we're living together... want to watch it together later?"
Smiling shyly, Song Su-a looked forward to the promise. When Do-jin nodded casually, Lee Seo-ha burst out in jealousy.
"Wait! What promises are you making with my friends without me? Whatever it is, I'm first! Do-jin is my dongsaeng, received from our parents! All of you step aside! Hey! Ryu A-rin! Don't rub your boobs against him like a sly fox!"
"Huh? Do-jin seems to like it though..."
"Song Su-a! And why are you holding my dongsaeng's hand?!"
"Well, we agreed to watch a movie."
Lee Do-jin was also flustered. This wasn't how the noonas used to touch him before.
"... I'm hungry. I couldn't eat anything since morning waiting for the noonas."
"Ah, right! We bought delicious food for a party!"
"Do you like tteokbokki?"
"Pizza?"
"I like everything."
"Good."
Soon, food packaged from somewhere was laid out one by one on the large dining table.
As each took their seat, they opened cans of beer and topics of conversation flowed out one by one.
"... Not to rush you, but have you thought about what you'll do from now on?"
Of course, he had been thinking about his career for a long time... Since he spent his elementary, middle, and high school years at an Academy that provided early education related to Hunters, it was natural to go into a related field.
He also obtained his Hunter license upon graduation.
What exactly he would do as a Hunter was what mattered going forward.
"I'm thinking of working as an Agent for a while."
Hunters are broadly divided into three types.
First, Hunters, literally hunters, who enter the Tower, kill monsters, and bring out the byproducts—the most common type.
Second, Agents, who belong to corporations or specific organizations, protecting assets or people.
Third, Rogues, criminals who use superhuman power from mana for personal gain.
All three are generally called Hunters.
Just like how 'Poclain' is originally a company name but is used as a generic term for excavators.
"... An Agent, not a bad choice."
"Finally we get a reliable connection too? Wow wow...."
Compared to Ryu A-rin and Song Su-a, Lee Seo-ha's expression was not bright. Because she was family, she knew. Why her only younger brother wanted to become an Agent.
'As expected... it's because of father....'
