Added 2025-08-30 19:33:34 +0000 UTCEP.196: Triangle Date!!
Suddenly, Mihyun came up with this suggestion:
She’d come along to the drinking party, and then I’d take turns sneaking away to bang one girl at a time.
‘Oh... what a perfect scenario, isn’t it?’
“So I can just say you’re coming because you have something to ask Go Joohee?”
“Yeah, exactly. I actually do want to ask her about how she does her streams and stuff.”
“Mmm... Well, if that’s the story, it won’t seem all that strange?”
And right on cue, a reply came from Yeonwoo.
Lee Yeon-woo: Great. But how about we meet this weekend? I have some work during the week... Is Saturday good?
Work, huh.
Is it kiss room work, or does she have something else?
Kang Hyunseong: Sure. Should I tell Joohee noona?
Lee Yeon-woo: Yeah. Please~
Okay.
Today is Thursday, so we’ve still got a bit of time until Saturday.
After I finished answering, Mihyun was still lying face-down on the bed, with me still inside her.
Texting on her phone.
Feeling a bit mischievous,
I smacked Mihyun’s ass hard.
Slap!
“Ow! Hey, why?!”
“Just felt like it. Your ass looked so firm.”
“Damn... Don’t slap it so hard.”
An unexpected event popped up in the middle of sex,
so after taking care of messages and such, I started pounding again.
It’s funny when you think about it, but out of all the girls I’ve ever been with, I’ve probably had sex with Mihyun the most.
“How many times have we done it, you think?”
“Hmm... In February it was almost every day... and now it’s May, so... Definitely over a hundred times, yeah?”
A hundred.
If I do the math, it’s probably an average of three times a day for three months.
Having sex with my own sister over a hundred times.
I must be some kind of crazy bastard.
And just the past week alone, I only did it with Mihyun (well, except sometimes with Mom), so I think that’s another 30 times or so.
Anyway,
now that the other business was settled, time to finish quickly.
“Okay, I’m gonna cum.”
“Mmm... ah, ah... ah....!”
See, having sex in a motel is great for moments like this.
You don’t have to hold back any moans at all.
I thrusted quickly to bring myself to the edge, pulled out at the last second,
flipped Mihyun onto her back, and blasted the tadpoles right into her mouth.
“Whoa... that’s... way too much...”
“Swallow it all. Good girl.”
“Heuuh...”
Gulp.
Even though I cum several times more than most men, Mihyun just grumbled a bit and swallowed it all carefully, even opening her mouth to show she’d gulped it down.
By now, after probably drinking my semen at least twenty times in our sex, Mihyun was so used to it that she might even be starting to enjoy the taste.
“Haah... haah... Whoa... Oppa, your cum is so thick. It’s like cream.”
“What? You like the taste?”
“...It’s not bad.”
She stroked her skin as she said that.
“Oppa! I think my skin got softer.”
“That’s what happens when you keep gulping down my cum.”
Kidding aside,
As the 7-day exclusive contract with Mihyun neared its end,
her skin glowed more and more the less time we had left.
Seriously, is she a succubus or something?
She absorbs my essence for a week and comes out all glowing with energy.
It’s like something out of a martial arts novel, that “draining yang to nourish yin” stuff.
Anyway, after a week of sucking up all my energy, Mihyun looked as happy as her healthy skin.
Lying next to her, I groped her breast and asked how she felt.
“Hey... So, was it nice just being with Oppa for a week?”
“Mmmm~ It was pretty fun. Hehe. We even went on a baseball stadium date.”
“Hehe. So now you’ll do anything I say, right?”
“I’ll think about it...”
“Hey, we had a deal, you know!”
“Nothing too crazy though.”
Don’t worry.
Even so, you’re my only little sister.
It’s not like I’d ever do to you what I do with Go Joohee.
Still... hehehe.
The thought of being able to try more stimulating and thrilling things with Mihyun made me grin.
Now that my agreement with Mihyun was finished,
the cock that had been exclusively hers for a week
would be released as a public good for more girls.
A thing to benefit all women equally monopolizing it just wasn’t right.
It goes against the free-market principles of anti-monopoly, after all.
After spending a week only on Mihyun, I was looking forward to seeing the others I’d neglected Mom, So-hye, Go Joohee, and Yeonwoo...
“Not a little sad you won’t have exclusive use of Oppa’s big cock anymore? Heh.”
“Not at all!”
“Huh? What?”
“Honestly, five or six times a day is kind of overkill. You’re like an animal... I really thought my pussy was gonna break.”
“Heh. I was going overboard to serve you, you know...”
“Psh. You just kept doing it to satisfy your own sex drive even when I said stop.”
“Heh...”
Surprisingly, Mihyun found it a bit much to monopolize my stamina all by herself.
Yeah, doing it five times a day for a week straight...
It’s harder than it sounds.
Apparently she couldn’t quite handle it on her own.
“So, you don't mind if I do it with other girls again?”
“What? Like I could stop you from going around screwing all sorts of girls. Jeez, last year you were still a virgin. But you have to save at least one or two shots a day for me, got it?”
“We’ll see about that~”
“Hey! Promise me for real!”
Anyway...
Now that I’ve shaken off the 7-day restriction, time to see my original, loyal girl first.
=====
“Hyunseong~ It’s been a while! How’ve you been?”
Of course, the very next day,
I met up with So-hye at school.
Honestly, I’d been wanting a break, and since Mihyun demanded to keep me to herself for a week, I skipped all my classes.
The excuse?
That my grandfather was sick.
Which wasn’t a total lie.
Grandpa is getting up there in years, and complains about one ache or another, so it’s not like it’s made up.
I only added the minor fib that I actually spent a whole week out of town.
“Yeah, So-hye, you doing well?”
“I missed you so much~”
“S-sorry about that...”
I couldn’t help but feel guilty.
She’s my official girlfriend, after all, and while Mom and Mihyun are family, I’d been cheating on her with other girls right here at our school Go Joohee, Lee Yeonwoo, and Shin Mirae.
‘Man... I’m really a terrible guy.’
So-hye’s sincere reaction made me feel even guiltier.
“It’s okay~ You came back after a family emergency. Is your grandpa better?”
“Uh, yeah. He’s fine now. Totally back to normal... ahaha.”
“That’s great! I’m so relieved!”
She didn’t doubt me at all so pure and trusting.
Sorry, So-hye...
That’s why I wanted to treat her extra well today.
We’d made plans to have dinner at 5:30, early since her curfew is 7, so we had to pick somewhere close by.
“Let’s eat somewhere nice tonight, since it’s been so long.”
“Okay. Oh, and I have some good news too!”
“Yeah? What is it?”
“I fibbed to my dad and told him I’d stay out until 9 tonight! Kyaa!”
“What?!”
Everyone remembers,
So-hye’s dad is Pastor Im...
The infamous bastard, as I learned from Gwak Youngchul’s video...
Of course, he’s also known as an upright pastor publicly.
Behind the scenes, he was secretly being bribed with sexual favors by bastards like Gwak Youngchul,
so he’s extra strict with So-hye even now she still has to be home by 7 every night.
Suddenly she’s allowed a late curfew?
And so honest a girl as So-hye lied to break it herself?
Something’s off.
“How’d you manage that lie?”
“Oh~ I told him I’d be hanging out with a girl friend.”
“With a girl friend?”
“I mean, you know Mirae sunbae, right?”
“...Yeah, I do.”
Oh, do I ever.
That was the senior I had a one-night stand with...
It was during finals week, when I was stressed, she hit on me, and I went for it.
But it was just a one-night thing, no contact after that.
While I wiped some nervous sweat from my brow, clueless So-hye continued innocently.
“Sunbae said she wanted to help me have a longer date with you...”
“Wait. She actually suggested that?”
“Yeah, we got close! While you were away that week, she ate all her meals with me at the school cafeteria and we became really good friends!”
“Uh, that so.”
“She’s so nice! Anyway, when I told her I was meeting you, she said not to worry about curfew and even offered to treat us to dinner!”
“W-wait, she’s coming too?”
What the hell.
Seriously.
A girl I cheated with,
got to know the girl I cheated on, my innocent underclassman,
and now is tagging along as a chaperone on our date?!
Is this for real?!
My internal warning alarms blared loudly.
But then...
How pure is So-hye, when she doesn’t mind another girl barging in on our date?
“So, what then?”
“Nothing, just that. She said she’d call my dad while we’re eating together so he’d be cool with it.”
“Uh, right...”
“Isn’t that great?”
Apparently her dad, Pastor Im, always calls immediately if she’s out past curfew.
Sigh...
I guess I’m supposed to be happy about this, huh?
=====
Our first-year class ended a little early, so just like she’d said, So-hye and I waited outside the classroom where Mirae sunbae’s class was held.
After about ten minutes, Mirae sunbae appeared.
She wore a spaghetti strap top with a cardigan and a flowing pastel-pink tennis skirt.
Perfect spring date outfit.
It had been a while since I’d seen her, but as soon as she spotted me, she smiled and waved.
“Oh my! Hyunseong, it’s been ages~”
“Ah, hi, sunbae.”
“Hello, unni!”
“Sorry for crashing your date. I’m being a total third wheel, huh?”
You could say that.
But I guess So-hye is just too nice to see it as bothersome.
“Not at all, unni! You’re just helping me by covering with my dad.”
“It’s not just that I really wanted to spend time with you both and chat. That’s all.”
“And Hyunseong said he’d treat us this time!”
“What? Wow, Hyunseong, you’re a gentleman.”
“Ah, haha...”
“Hehe, but isn’t this place expensive?”
“It’s fine. Haha. Don’t worry about it.”
So,
our couple became a trio with “the extra appendage” Shin Mirae joining the date.
It was a weird situation.
So-hye clearly has no clue I cheated,
but the one I slept with, Shin Mirae, deliberately got close to her while I was away.
This is just way too deliberate.
But So-hye was happy with it, so even though I felt awkward, I just went along.
We picked a trendy fusion Italian place girls love.
“Oh, this place is so nice! Hyunseong, you’ve got good taste. So-hye, you’re lucky!”
“Ahaha... yeah.”
“Right? But Hyunseong, isn’t it a bit expensive?”
“It’s cool! Don’t worry...”
I was getting all sweaty and nervous, so I downed my welcome drink in one shot.
My stomach... is in knots.
