Hide!
Hide!
After Kang Si-woo headed toward the washing machine, Kang Ji-eun quietly entered his room.
The moment she closed and locked the door tight, the tension that had been weighing on her shoulders eased slightly.
"...Phew."
Soon after, Kang Ji-eun slowly approached Kang Si-woo's bed, which was placed on one side of the room.
Perhaps because he hadn't made his bed after waking up, the blankets were strewn about carelessly.
"..."
This had been her goal from the start.
Kang Si-woo's room.
If one were to ask if her goal was to tidy up her younger brother's room, that would be a miscalculation.
To achieve her goal, Kang Ji-eun—

buried her face in the blanket and pillow that seemed to still hold his body heat.
"Snnniff...♡"
Kang Si-woo's scent filled her nose.
To remember his scent more deeply, Kang Ji-eun buried her face deeper into the blanket and inhaled deeply.
Her chest tingled and heated up.
It felt as if his hands, which she had felt while getting a massage yesterday, were still lingering on her shoulders and neck.
After having her face buried like that for a while, she lifted her head while keeping the blanket pressed against her nose and scanned the surroundings.
Just as she was looking for an object that might be more heavily soaked in Kang Si-woo's scent—
The trash can.
There was a small trash can placed in the corner next to the desk.
In an instant, Kang Ji-eun's mind began to race.
'Si, Si-woo is a man too... could it be.'
Her heart beat rapidly.
A memory of a post she had seen on the internet surfaced.
If there are tissues in the trash can in a man's room, unless he has a cold, it's mostly... 'that'.
Clutching her pounding chest, Kang Ji-eun cautiously approached the trash can.
At first, she couldn't see the contents well.
One step, then another.
But as she got closer to the trash can, a pile of crumpled white tissues faintly revealed itself inside.
"...Gulp."
Her hands trembled.
'Those tissues, really...'
Just as Kang Ji-eun was about to slowly reach out, holding her breath.
Clack—!
The bedroom door was suddenly flung open roughly.
"I, I'll clean it up!"
Kang Si-woo ran in, panting.
The trash can.
I hadn't emptied the trash can.
That was the thing I thought I had forgotten.
Since I usually emptied it separately every Sunday, even though I hadn't masturbated in the last few days, the traces from before were still quite significant.
As soon as I put all the clothes in the dryer and started it, I remembered that fact and ran to my room.
Clack—!
"I, I'll clean it up!"
"Kyaa?!"

Perhaps because I opened the door so suddenly, Kang Ji-eun let out a somewhat cute scream.
I quickly averted my gaze, and it seemed she hadn't cleaned out the trash can yet.
Catching my panting breath, I entered the room and blocked the front of the trash can.
"Uh, what was it. I finished running the dryer."
As I went in front of Kang Ji-eun, who was standing there somewhat awkwardly, and turned my back to the trash can so she couldn't see it, Kang Ji-eun was visibly flustered.
"Ah, um... I could clean it up, though...?"
"Noona, you must be tired, so you can just rest."
I couldn't bring myself to corrupt that kind and pure heart of hers, insisting on cleaning it herself even though she must be tired.
"I, it's not really that tiring..."
But for some reason, she kept refusing my help and fidgeting with her hands.
"It's really fine, so hurry up and go out and rest."
Thinking that Kang Ji-eun might see the trash can, I became desperate—
Grab.
"...Ah."
I gently grabbed Kang Ji-eun's wrist and led her toward the door.
Fortunately, Kang Ji-eun didn't resist and followed along obediently.
"Okay..."
She answered quietly, and as I opened the door for her, she left the room silently.
The moment the door closed, I let out a long sigh.
"Haa... thank goodness."
The tension in my body loosened little by little, and I looked around the room.
'But, what is this?'
It must be my imagination that it looks like nothing was cleaned.
After some time had passed.
I finished vacuuming and mopping Kang Ji-eun's room, Kang Yu-na's room, and even my own room.
Now, all that was left was Kang Seo-ah's room.
Since Kang Yu-na had already vacuumed Kang Seo-ah's room, I stood in front of Seo-ah's room holding the mop.
The moment Kang Seo-ah watched porn in my room flashed through my mind.
Hoping she would continue to pretend not to know, I cautiously knocked on the door.
Knock, knock.
"Seo-ah, I'm coming in."
There was no answer.
I quietly opened the door and went inside.
Kang Seo-ah was sitting on the bed looking at her tablet, but when I entered, she lifted her head and glared at me.
Her gaze was cold as usual.
"Hmph."
Kang Seo-ah snorted and stood up, holding her tablet.
"Move."
She brushed past me and left the room.
After the sound of the door closing was heard, her footsteps faded away in the hallway.
It seemed she had gone to the living room.
I let out a sigh.
'...It's a relief, though.'
Although it became easier to clean because Kang Seo-ah vacated the room, my worries about how to bridge the awkward relationship with her grew even larger.
'What on earth does Seo-ah think of me?'
The operation was a success.
The operation to pretend to go out to the living room while Kang Si-woo was cleaning his room, and then infiltrate Kang Si-woo's room.
The moment she quietly closed the door, her heart pounded.
The air inside the room was refreshing, as if the cleaning had just finished.
Kang Si-woo's scent had almost disappeared from the blanket and pillow as well.
It seemed even the ventilation had been done properly.
'...It's a shame.'
Kang Seo-ah sighed softly.
But it was too early to give up.
"..."
The closet.
Having discovered the closet that would be stuffed with the clothes Kang Si-woo wears every day, Kang Seo-ah slowly approached the closet.
With trembling hands, she put down the tablet she was holding on the floor, grabbed the door handle, and—
Creak—
As she opened the closet, which felt like Pandora's box, the clothes Kang Si-woo had worn were hanging densely.
Shirts, sportswear, the t-shirts he usually wore.
On top of that, even his underwear, although it was after the laundry was done.
A familiar scent that struck her nose came rushing in.
"...Haaa."
Kang Si-woo's scent.
Sweat, body heat, and Kang Si-woo's unique smell were soaked into the fabric.
Kang Seo-ah buried her body into the closet without hesitation.
She buried her face among Kang Si-woo's clothes and inhaled deeply.
"Hnnn..."
Kang Si-woo's smell filled her nose.
Her chest tingled and heated up.
"Oppa...♡"
Her hand went inside her pants on its own.
She knew she should refrain from masturbating in Kang Si-woo's room, but her instinct was refusing that.
Jji-beup♡
"Ah-heut..."
As her finger touched her vulva, which was already damp and wet, a small moan leaked out.
Before she knew it, Kang Seo-ah was rubbing the t-shirt Kang Si-woo wore most often against her face, and began to gently rub her clitoris.
"Oppa is a pervert too, so... for me, this much is fine, right...♡?"
Kang Si-woo watching erotic videos and her current actions seemed unrelated, but to Kang Seo-ah, whose brain circuits were already broken, such things didn't matter.
As she masturbated while smelling Kang Si-woo's scent, her mind was turning white.
Love juice flowed down her fingers, soaking her pants, and was about to drip onto the closet floor.
"Hnn... Oppa... touch me...♡"
Kang Seo-ah's imagination became increasingly explicit.
Kang Si-woo entering this room where she was masturbating, and ravishing her...?
'W, wait a second.'
At that moment—
Click.
"...!!"
Kang Seo-ah's body stiffened instantly.
It was because she heard the sound of the door opening, as if Kang Si-woo had finished mopping.
'Wh, what do I do!?'
She panicked, unable to stop her fingers.
Because the climax was approaching quickly, her thoughts weren't functioning properly.
But Kang Si-woo was already returning.
She hadn't realized that since he was only mopping, it wouldn't take that long.
"U, uung... what do I do...♡"
Kang Seo-ah first hurriedly pulled her hand out and tried to pull up her pants.
But her legs were shaking, so she couldn't move properly.
The footsteps were getting closer.
'Hi, hide...!'
She quickly picked up the tablet she had put on the floor, pushed it into the back of the closet along with her pants that she hadn't been able to pull up, and then buried herself.
She hid her body as much as possible among Kang Si-woo's clothes and held her breath.
A short while later.
Creak—
The door opened.
Kang Seo-ah held her breath and hid her body as much as possible inside the closet.
Through the gap in the slightly open closet door, Kang Si-woo's figure was faintly visible.
Kang Si-woo, who had entered empty-handed as if he had already left the mop behind, flopped down onto the desk chair.
Fortunately, the misfortune of him opening the closet to change his clothes immediately did not occur.
He seemed to be resting for a moment while looking at his phone with a sigh, but soon he opened a major-related textbook and started writing something.
'...Is he studying?'
Kang Seo-ah watched him through the gap in the door and quietly swallowed her saliva.

Kang Si-woo's appearance as he focused and moved his pen, his slightly furrowed brow, his tired but serious gaze.
Suddenly, an impulse surged.
'I want to draw him...'
Of course, the impulse to continue masturbating in this state also surged, but excluding that because Kang Si-woo would hear it.
It was an intense desire that surged, wanting to draw this scene, Kang Si-woo's focused face, and keep it for herself.
She carefully picked up her tablet and started taking pictures with the flash completely turned off.
Scratch, scratch.
Even though she was taking pictures, instead of a clicking sound, only the sound of Kang Si-woo's mechanical pencil moving could be heard.
Praising her past self for having taken measures so that the camera wouldn't make a sound, Kang Seo-ah began to take several photos while holding her breath.
Kang Si-woo's fingers, the nape of his neck, even his focused eyes.
Had it already been about 20 minutes?
The inside of the closet was becoming increasingly stuffy.
She was short of breath, but because Kang Si-woo's scent was soaked throughout the closet, she actually felt good.
'It would be fine if I suffocated like this.'
She even had such a contradictory thought.
At that moment.
Kang Si-woo suddenly put down his pen, stretched, and then—
turned on the computer.
