🕑 Added 2025-08-16 19:50:03 +0000 UTCEP.187: Where Is the Date Venue With Mihyun??
Early May.
Saturday morning.
A gentle spring breeze was blowing,
the weather was clear and bright,
and with midterms over, psychological relief was in the air.
It was a perfect day for a date with a girl.
With my little sister.
A date with my little sister.
If you were a normal pair of siblings, just hearing that would probably give you hives,
but Mihyun and I aren’t normal siblings.
We’ve had sex over 100 times in just the last two months... Honestly, now we feel more like lovers than siblings.
So what’s the point of talking about “real” brother-sister relationships at this point...
But even though we’d had sex so much
we’d only been on one official date.
After the movie theater date (and of course, our first bathroom sex), that was it...
So I think Mihyun was secretly feeling some frustration from that.
‘Oppa, do you just want my body?’
She never directly said it, but I could feel it in the air.
Plus, with So-hye, Go Joo-hee, and even our mom joining my “harem(?)”,
it really became biologically impossible to dedicate myself to Mihyun alone.
Back in the day, we’d have sex 4–5 times a day, but these days it’s down to just once or twice.
So to make up for how I’d been neglecting her, I wanted to do everything Mihyun wanted.
Of course... if I do everything she wants for a week?
Hehehe...
She said I'd get a full-access free pass to do anything I wanted with my busty, cow-like little sister afterwards even the roughest play.
Mihyun.
I’ll tolerate any of your tantrums, any complaining see you after a week.
Of course, I still had to take care of business first
First step
"I'm sorry, So-hye... Yeah. I just have some family stuff for a week... Huh? Oh, it’s nothing major, I just think I have to visit my grandfather in the countryside. Yeah! Yeah... Then! We’ll go out on a date when it’s over. There? Le Maison? Sure. My treat, hehe. Okay. Love you~ yeah!”
I basically groveled to So-hye, telling her a total lie about urgent family stuff.
“Sorry~ I love you~”
And after that...
There was Mihyun glaring at me with a rotten face.
“Oppa.”
“What?”
“Just cut your dick off already.”
=====
Of course, it wasn’t easy from the start.
“Aren’t you done yet?”
“Almost~ Just a little more.”
“You said that 30 minutes ago.”
“I’m just trying to look nice.”
Like any other girl getting ready for a date,
Mihyun was going all-out with her makeup and outfit.
Watching her, I started to wonder...
‘How far does Mihyun want to go with me?’
Not in terms of physical destinations, but...
how far does she want to take her relationship with her own big brother?
One thing was clear
she didn’t seem content with just physical pleasure.
If she just wanted the sex, she wouldn’t be so excited about getting ready for a date.
“Hey, you look great. The makeup turned out perfect.”
“Really? I look pretty?”
“Yeah. So hurry up already...”
“Then pick out my outfit for me.”
“Huh?”
“Hurry. Which one looks better, this or this?”
...So she seemed to want to do everything normal couples do.
“Th-the red one?”
“Wrong. You really have no sense, Oppa.”
“...You’re just going to wear whatever you want anyway, so why ask me?”
“That’s what makes it fun.”
Well, anyway, when she was finally fully decked out
“Wow. You look amazing. I’m not just saying that.”
“Really?”
“Yeah. You look like a literal goddess.”
I wasn’t kidding she really looked gorgeous.
Of course, she was always pretty before,
but since at home we’re usually half-dressed with no makeup,
it’s rare to see the full makeup routine.
Even bare-faced, she looked as pretty as other girls with full makeup, and I’d always thought "Ah, my sister really is pretty..."
But with full makeup, I realized I’d been underestimating her.
Honestly,
just in terms of looks, the best I've seen is Lee Yeon-woo, but now it’s a dead heat.
“Hehe, I’m ready.”
“Okay, so where are we going?”
“Curious? Five bucks if you want to know.”
I’d promised to do whatever she wanted for a week, but...
Why did we have to start so early in the morning?
But, in a petty mood, I just pouted and said
“No, not really.”
“...Such a contrarian. Sheesh.”
“I’ll do whatever you want, so lead the way.”
“Fine.”
Admiring Mihyun’s looks, at times she really seemed just like an ordinary little sister.
After a whole hour of makeup, hair, and outfit, she finally emerged
Not just with herself, but also dragging what seemed like a pre-packed suitcase.
“What’s with the suitcase? Are we going on a trip?”
“Yeah... hehe... you’ll see.”
I followed Mihyun to wherever she was going
“Seoul Station?”
====
“What, are we going to Daejeon?”
“Yeah. To the baseball stadium.”
“If you want to see baseball, we could just go to Jamsil... Wait, you’re actually a baseball fan?”
It was weird,
she was dragging me off to the train station,
all the way to a train to Daejeon?
No way, is she actually a baseball fan?
“You didn’t know?”
“Of course not. You’ve never watched a baseball game before.”
“I-I’ve been really into the Hanwha Eagles lately!”
Stammering, obviously hiding something.
I sometimes watch baseball on TV, but not enough to go all the way to the stadium.
And suddenly she wants to see a team she’s never cared about before, and it’s not even from Seoul?
“Suspicious... there’s no way you’re a baseball nerd.”
“...What’s so suspicious? I can like baseball too.”
“Explain the rules, then.”
“...”
“How do you score?”
“You... hit the ball, right?”
“So you put it in the goal?”
“I-is that right? Is that how it goes? Uh, maybe not...”
Ugh. Never mind.
“But, did you reserve tickets for today’s game?”
“Yup! It was hard since Hanwha’s new stadium is booked solid.”
“...I doubt it’s that hard.”
“Huh? When I reserved, it was almost sold out right after.”
“Anyway... Is going to a baseball game really what you wanted to do for our date?”
“Well... sort of. Oh, and I want to go somewhere else, too!”
“Where?”
“When it’s Daejeon, it’s got to be Sangsimdang Bakery. I’ve always wanted to try their bread!”
Of course.
The baseball game was just an excuse, the real goal was the food.
“The strawberry shortcake thing?”
“They probably sold out already, but the jambon-beurre sounds delicious. You’ll buy it for me, right? Hm?”
“...Fine. I’ll buy for you.”
“Yay!”
Yeah.
Even though I never wrote it in this (supposedly fictional) story up to episode 187,
she’s notorious for her love of pastries.
She always preferred bread to meals as a kid, maybe that’s why all her “bread-weight” went straight to her chest and turned her into such a busty girl.
Not that girls being crazy for desserts is anything weird.
Back when she was a delinquent, she really lived up to the “bread-shuttle” name, always ordering her underlings to fetch her bread.
“You don’t bully the bread-shuttle kids anymore, right?”
“Ugh. That’s ancient history. Now I just sleep at school.”
“How am I supposed to believe that?”
“Jerk!”
We’re twins in the same grade at the same school (different classes), so we know each other like old friends.
While talking about school stuff, the trip to Daejeon went by in a flash.
I’m in college,
she’s a year behind, still in high school so our topics don’t even overlap much.
“Kyunghoon, does he still not show up at school?”
“Yeah. He became a delivery guy, I heard.”
“Hm....”
For example, chatter about Kyunghoon, who flunked and got held back in our class...
“What about Gyutae? Still going to school?”
“That guy? Did I tell you he’s a BJ?”
“You mentioned that saying he’s a total nobody, talking behind his back.”
“...It’s not talking behind his back, just facts.”
Or about Gyutae, who went to the same college as me...
“Hey. Are you still dating Habin?”
“Huh... why? Jealous?”
“Pfft, why would I be?”
“Then it’s okay if I kiss him?”
“You still haven’t?”
“You told me not to.”
“And he’s still sticking with you and calling it dating?”
Or about Yoon Habin, my classmate and (nominal) boyfriend.
Anyway, when we got on to talking about Habin,
Mihyun’s lips poked out in a cute pout again.
“Eugh. He keeps being clingy, it’s kind of annoying.”
“Then just dump him.”
“No?”
“Sigh. Why are you still dating him?”
“He’s my ATM. I’m running low on spending money these days.”
“Sigh... poor Habin... he can’t even touch you or kiss you, and he doesn’t even complain?”
“He has complaints but he just keeps his mouth shut since I won’t take it. Hehe.”
“Hm....”
Honestly, as my own sister and sex partner (probably words that shouldn’t go together, but anyway) I find her cute and pretty,
but to be objective, her personality is pretty rotten.
If I were in Habin’s shoes, I’d have probably offed myself by now.
Anyway, having all these chats made it feel like traveling with a best friend for the first time in ages.
When we were in high school, I studied like crazy due to an awful home situation,
and we were so poor it was unthinkable to spend money on a trip like this.
Just getting out of daily life, going to a new place and environment, really lightened my mood... it felt healing.
=====
“We’re here!”
“It’s my first time seeing a baseball stadium in person. It’s huge.”
“Right? I’m super excited too. My first live spectator sports event.”
Since it was her idea, Mihyun was really upbeat about this date.
Usually I just enjoyed her sexy body at home,
but seeing her so excited outside made me glad I came.
“Where... looks like with the tickets, you go in Gate 3.”
“Here?”
“Yup.”
Just like she reserved in the app, we entered through Gate 3.
Took the elevator from the lobby up to the top, the 4th floor.
“Fourth floor? Won’t we barely see anything?”
“Hehe... you’ll see. It’s a surprise.”
“...?”
You’d think we just came to see baseball, what’s the surprise?
But turns out, my guess was too run-of-the-mill.
“Oh...?”
“I saw this on YouTube and really wanted to try it myself~ I even brought swimsuits for us, Oppa~!”
The reason Mihyun wanted to come here despite not knowing a thing about baseball:
On the roof of the stadium, an endless blue infinity pool stretched before us.
“S-so we’re changing into swimsuits?”
“Of course! I splurged on a private jacuzzi reservation too! Go get changed in that locker room.”
“O-okay...”
It really was a surprise.
Never would have guessed we’d come to a baseball stadium and end up in swimsuits in the pool.
And after I dashed into the men’s changing room and hurried back out in my swimsuit...
“Tada! Oppa, what do you think?”
“...Holy shit.”
The swimsuit she was wearing
A mono-kini so sexy, her huge breasts were more than halfway exposed.
I mean, was she really going to wear that in a baseball stadium?
My head spun suddenly.
