Chapter Title: 5. Lee Ha-yoon Wants to Be Treated Like a Big Sister (3)
-----------------------------------------------------------------
Meanwhile.
Lee Ha-yoon's mind was overflowing with thoughts of What do I do now?
She had messed up right from the start.
If she had to make an excuse, it was because this was her first time, so she was nervous.
...Let's have sex.
Saying outright that she wanted to have sex with him right here—
Unlike the simulations she'd run through alone countless times, it was a line she just couldn't blurt out easily.
And then...
Right before entering the infirmary,
she ran into the principal walking out while on a phone call.
Her plan had completely fallen apart.
The only people who might visit the infirmary right now, excluding herself, were one or maybe two at most.
But factoring in the teachers too? The risk of getting caught was way too high.
Someone might knock on the door in the middle of them getting intimate.
In the worst case, someone could overhear her embarrassing moans...
Those thoughts raced nonstop through Lee Ha-yoon's head, making her heart pound so hard it felt like it was echoing right in her skull.
She'd come to the infirmary all smiles, thinking Today, I'll take the lead like a proper big sister!
Her only naive plan was something like If it seems risky, just lock the door—what's the big deal!
Was that really going to be okay?
And what about soundproofing...
"...Ah..."
Right then.
Seo Woo-jin's firm shoulder brushed right against her.
The infirmary door was locked.
Just the two of them, a guy and a girl.
One bed.
...Her body went rigid.
"Mind if I sit next to you?"
"...Y-yeah, it's fine. Go ahead..."
"Excuse me, then. Big Sis."
"......"
Shouldn't you say that before sitting down...?
Whatever.
Did he spray on some cologne or something?
A cool, refreshing scent she'd never noticed when chattering away with her friends tickled her nose.
She'd never smelled anything like it even talking with her guy friends... How intriguing.
...Anyway.
Now that she was this far in...
She had to do it...
...Sex.
"......"
He was already sitting on the bed. Bolting out with a Nope, I can't do it! wouldn't be very big-sisterly.
Just keep it quiet.
Even if she had to clamp her own mouth shut.
If anyone outside heard...
She'd really bite her tongue off.
For now, start by taking the lead with a kiss...
"Not much time, so I'll make it quick."
"...Mm."
...Too late again.
She'd been about to say something naughty first this time.
As she inwardly scolded herself, Lee Ha-yoon's gaze drifted to her fingertips.
A hand much larger and firmer than a woman's.
Her own fingertips gripped tightly in it.
"Exactly where does it hurt?"
Nowhere hurt at all.
It was just a fake illness.
From the way he'd just locked the door, he clearly knew it was fake too.
In other words, it was all theater.
At this point, screw it! She could pull out the two condoms from her pocket, toss them on his thigh, and naturally set the mood for what they both wanted.
...But.
She couldn't bring herself to end the act just yet.
"M-my pinky... the tip..."
"The tip, huh."
Otherwise, it'd turn into the same sloppy sex as yesterday.
The big sister pinned obediently beneath her little brother, moaning embarrassingly...
Sure, it felt good—of course it did!
Good enough that she'd spent half the night in the bath replaying it!
But now she had to steer things in the right direction.
No matter how inexperienced she was, she couldn't keep getting swept along by a younger guy forever.
A spark of determination ignited.
I'm still the one-year older big sister here.
If she showed any more embarrassing sides, her dignity as a big sister would hit rock bottom.
Like a big sister.
A relaxed attitude...
A composed demeanor...
Relaxed...
"......"
Lee Ha-yoon's eyes flicked back to her fingertips.
Because Seo Woo-jin, sitting beside her, let out a light sigh, and a warm energy faintly seeped into her finger.
...He knew full well it was fake.
Yet he was playing along, diligently "treating" her.
The Seo Woo-jin she'd seen at her place yesterday had felt a bit bolder.
Ah.
She got it.
Even Seo Woo-jin, who acted so skilled, must be embarrassed by a situation like this deep down.
Come to think of it, he was only twenty.
Same age as Ji-yoon, who was probably gaming hard at home right now.
So she didn't need to feel intimidated either.
If she just acted naturally as planned, she could easily seize control...!
Whoosh, ha, whoosh, ha—Lee Ha-yoon took deep breaths loud enough for Seo Woo-jin right next to her to hear.
As he pretended not to notice her odd behavior and closed his eyes,
a small shadow fell over his lap.
Because the self-proclaimed big sister had plopped right down on his thigh.
"W-Woo-jin."
"Yes."
"Um..."
"Um...?"
"...I prepared a little gift for you."
The die had been cast.
All that was left was to proceed calmly as planned.
No getting dragged around like yesterday. Show a relaxed side.
Gulp. Lee Ha-yoon swallowed hard.
"...Today, I'll make you feel good, big sis style..."
With that, she lightly lowered her head.
"......"
"......"
Their lips met.
Then parted.
Met again.
Parted once more.
Maybe because it was just lips touching and separating.
The infirmary held only the warm sunlight's gleam, no other sounds.
Lee Ha-yoon, eyes squeezed shut, wrapped her arms around Seo Woo-jin's neck and pressed her lips to his.
She'd been holding her breath, so each time their lips parted, a soft exhale escaped,
and thinking Hey, this isn't so bad after all gave her courage.
She tentatively stuck out her tongue, awkwardly licking his lips.
Is this right?
Doubt crept in, but she ignored it and kept going.
It was the ultimate fan service a hero could give a fan.
The best way to repay Seo Woo-jin, who'd helped her so many times.
...The greatest gift she could give the guy she'd set her heart on.
After continuing the soft kisses, Lee Ha-yoon rested her head on his shoulder for a moment to catch her breath.
Her cheeks were burning so hot from just a little kissing that she wanted to cool them down a bit.
Ahem. She'd been so nervous over something this simple.
Did she finally seem like a 'big sister' now? Was her older-woman charm coming through?
Next, she'd peel off Woo-jin's clothes layer by layer herself.
Because she was the big sister.
After cooling her cheeks a little, Lee Ha-yoon lifted her head with a shy grin.
"Mmph...?"
Just like that.
She hadn't expected him to kiss her right back.
"Heuph...? Mmph......"
Clearly, she was the one on top...
...Or not.
By the time she snapped out of it, her eye level matched Seo Woo-jin's.
...No. Accounting for her slightly bent neck, she was actually a bit lower.
Why?
In the midst of the sticky kiss, a cold sensation under her butt explained it.
...Distracted by the kissing,
she'd slipped off Seo Woo-jin's thigh and was now sitting on the bed.
"...Fwaah.... Mm... Mmph..."
And so.
Her one-year-younger little brother
was on top of her again, like last time.
"Mmph.... Nngh......"
Seo Woo-jin held her tight as he kissed her.
Her lips parted helplessly, tongues entwining,
saliva she couldn't swallow dripping drop by drop between their sweetly clinging lips,
and her head, which had only heard cute sounds moments ago, now creaked with wet, squelching noises.
"Fwaah...! Ha...! Ah......?"
What was this?
The same kiss...
No.
This one was even more embarrassing, so un-big-sister-like.
Why was her heart thumping like it would burst from her throat?
...Weird... right?
Before she could realize the answer, their wet lips overlapped again.
This was all wrong.
She wasn't showing any big-sister poise—instead, she was clinging to his neck like a spoiled kid. Embarrassing.
Gulping down the saliva flowing from his mouth between their lips. Perverted.
She had to take back control now.
I can make you feel good too...
Wait... just a... second...
"......"
"Pfhat....... Haa..."
Beyond lips connected by a string of sticky saliva.
Lee Ha-yoon, stupidly sticking out her tongue, looked up to meet Seo Woo-jin's eyes.
They were warm.
The problem was, that gaze looked at her like she was a cute pet.
Like he was watching to see how far her antics would go... A pride-wounding look.
...You think I can't kiss and you're laughing at your big sister, huh...
...I'm dead. For real.
"Again... I'll do it again..."
"Oh? But we're short on time. You sure?"
The act was over.
She climbed back onto Seo Woo-jin's thigh, lowering her head.
Ignoring her tied-up hair spilling over her shoulder.
Solely to kiss.
"You're cute enough normally, Sis."
"Sh-shut up... I have to get revenge......"
...Exactly.
Swallowing her words, she pressed her lips to his.
This time, she wasn't just smooching like elementary school kids.
She slipped her tongue between his lips just like he'd done to her,
and even teasingly pressed her lips to his relaxed neck as if accepting his playfulness.
...A hickey.
She didn't know exactly how to make one, but pressing her lips there should do it.
She'd leave tons.
So many he'd have to wear a scarf outside.
Plenty.
"......Eut..."
While kissing his neck repeatedly and mixing tongues again.
A soft touch grazed her butt, sending chills up her spine.
It was Seo Woo-jin's fingers.
Fingers that had been gently on her pinky just moments ago.
Now those fingers
effortlessly hiked up her defenseless school skirt,
gripping her waistline to expose her pure white panties.
...For him to toy with as he pleased.
This little brother,
playing with his big sister's body.
"Chup.... Fwahp.... Mmph..."
Don't.
It's my turn.
Even protesting with her tongue, nothing changed.
Seo Woo-jin casually looked up at her, accepting the kisses.
His fingers began lightly stroking over her panties.
...No big deal.
Nothing particularly good about it...
Just stroking over panties—something she'd done to death since middle school.
She could ignore this much and...
".... Ahak..., W-wait.... Just a......?"
Ignore it?
"There, ...! ......"
She tried to ignore it.
But.
"You said you wanted revenge."
"Sch... Sch......"
"...No kiss?"
"Y-you keep touching me all weird......"
"Weird how?"
"......"
"Can't hear you, Sis."
"......"
His thick fingers were toying with her down there so strangely...
Much better than when she did it herself, prodding and poking...
She could only bury her forehead in his firm shoulder,
her hips twitching helplessly.
Even though she was the older big sister.
Pathetically,
as she came lightly with her face buried in Seo Woo-jin's shoulder,
"...Lift your head."
"Hic....... He...?"
His pleasant baritone rumbled into her flushed ears.
Without thinking, she raised her face a little.
"Chup.... Fwahp.... Mm..."
Just like last night in her apartment when she'd gotten it bad.
Like the time before that in the bathroom, pretending to sleep while rubbing her cheek on Ji-yoon and getting wrecked.
After slowly receiving his saliva,
when their mixed saliva pooled at the back of her throat.
Gulp, gulp.
She moistened her throat sweetly.
Big sister or not.
She'd wanted to show a more relaxed, leisurely side.
...But like a cheap dog on a leash, dragged along.
Lifted from her seat by force...
Wrapping her legs around Seo Woo-jin's waist.
Laid down on the opposite side of the bed.
Gulp...,
gulp.
