Voyeurism
Hummm—
The boot-up sound rang out softly.
Because of the angle, she couldn't see the monitor, but thanks to the sound, she knew at least that Kang Si-woo had turned on the computer.
'Is he trying to watch a lecture or something?'
Kang Seo-ah vaguely guessed that the reason he'd suddenly turn on the computer while studying was for an online lecture.
Then, Kang Si-woo suddenly stood up from his seat.
Kang Seo-ah was startled for a moment, but she was relieved when she realized he wasn't coming toward her, but heading for the door.
She wondered if he was going out to the living room to get a drink of water, but—
Click.
Soon after, along with the sound of the door locking, Kang Si-woo returned to his seat.
'Why the door...?'
No way.
Kang Seo-ah began to doubt if the current situation was just her own delusion.
Turning on the computer and suddenly locking the door.
'N-now?!'
No matter how she looked at it, to Kang Seo-ah, the current situation looked like nothing other than Kang Si-woo about to start masturbating.
Thump. Thump. Thump.
The heart that had calmed down while watching Kang Si-woo study began to beat violently again.
It felt like it was beating so loudly that she worried she might get caught because of the sound of her heart.
As she observed Kang Si-woo with such intense focus that her eyes felt like they were going to pop out along with her heart.
Sreuk—

"...!"
At that moment, Kang Seo-ah forgot how to breathe.
It was because Kang Si-woo had pulled down the shorts he was wearing like pajamas, revealing his genitals completely.
Half-erect, and perhaps because of the weight, it was drooping slightly downward.
Her own brother's cock, which she hadn't properly seen since they were young.
It was completely different from the small, cute thing in her memories.
A thick, long, vein-popping, writhing organ filled her vision.
Saliva instantly pooled in Kang Seo-ah's mouth.
Her throat moved on its own, and she swallowed.
And at the same time, her pussy, which had been feeling unsatisfied from not reaching climax, began to get hot and wet again.
Just then, Kang Si-woo put earphones in his ears and began operating the computer.
'P-photo! No... video.'
Kang Seo-ah hurriedly opened the camera app on her tablet.
Every moment that Kang Si-woo's cock was visible.
Press—
To keep it just as it was, she pressed the record button with trembling fingers.
The recording started without a sound.
From the moment Kang Si-woo's cock wasn't fully erect, to the moment it slowly became hard and erect.
The tablet camera, placed at an appropriate angle, was capturing the whole thing while zoomed in.
Kang Si-woo looked at the monitor screen and wrapped one hand around his genitals.
It seemed he had found the video he wanted.
As he began to slowly move his hand up and down, Kang Seo-ah's eyes widened.
'Oppa is really masturbating in front of me...'
Her body grew hotter and hotter from the sense of immorality that she was secretly watching Kang Si-woo masturbate, and even recording it.
She felt her instinct and reason fighting.
'I shouldn't... make any noise...'
But the moment she confirmed that Kang Si-woo had an earphone in one ear.

Her hand was already heading down toward her pussy.
Splosh...♡
"Hup...♡!"
Because of the tension and excitement, so much love juice came out that when her fingers touched her soaked pussy, the sound of water could be heard.
Kang Seo-ah covered her mouth with one hand and began rubbing her clitoris with the other.
'What do I do...♡ What do I do♡'
Tak♡ Tak♡ Tak♡—
She moved her fingers in time with the speed at which Kang Si-woo was moving his hand while watching the screen.
Splosh♡ Splosh♡ Splosh♡—
"Ha-up...♡"
A small moan leaked out between the fingers covering her mouth.
Fortunately, it seemed Kang Si-woo didn't sense anything strange, thanks to him being focused on the sound in the video.
Even in that dangerous situation, she couldn't take her eyes off him.
She was capturing the sight of Kang Si-woo's cock fully erect and writhing with bulging veins without blinking once.

'If, if something like that goes inside me...'
Kang Seo-ah trembled as she applied the size and thickness she had only imagined to her delusions.
The scene of Kang Si-woo's glans forcing its way into her vagina, the scene of Kang Si-woo thrusting his hips to get her pregnant.
And as the real-life Kang Si-woo moved his hand faster and faster, Kang Seo-ah's finger movements also became faster.
Love juice flowed down to her wrist, and the sound of it dripping onto the closet floor rang out softly.
She continued masturbating, covering her mouth even tighter, even with tears welling up in her eyes.
Kang Si-woo was breathing more and more roughly, focused on the screen.
Kang Seo-ah was struggling not to miss that sight, feeling her own climax approaching.
Both of their hands moved faster and faster.
Then, finally.
"...Ugh."
Splurt— Splurrrrt—!
Kang Si-woo groaned lowly and began to ejaculate.
White, cloudy fluid sprayed violently from the tip of his glans onto the tissue.
The amount looked much larger than what Kang Seo-ah had imagined.
The semen shot out like a stream, going past the tissue and dropping onto the desk with a thud, thud, creating small stains.
The moment she saw that sight, Kang Seo-ah also reached her climax at the same time.

Squirt♡ Pshhh♡—
"...♡♡—!!"
A suppressed moan leaked out between the fingers covering her mouth.
Kang Seo-ah's pussy contracted, and clear love juice shot out forcefully along her fingers toward the floor.
Kang Seo-ah gritted her teeth at the climax of stimulation, more intense than any masturbation she had done before.
Her legs trembled, and her vision went white.
Kang Seo-ah panted for a while, soaking in the afterglow.
After some time had passed.
It seemed Kang Si-woo's afterglow of ejaculation had also faded, so he pulled out more tissue, roughly wiped the semen that had splattered around his cock—
Clack!
He left the used tissues on the desk, pulled up his pants, and left the room.
Listening carefully to his footsteps, he was heading to the bathroom.
Not missing that moment, Kang Seo-ah quickly opened the closet door slightly and came out.
The scent of Kang Si-woo's semen, like chestnut blossoms, which she hadn't felt in the closet, was spreading thickly throughout the room.
"...Ah♡"
An impulse surged once again at that scent.
An intense desire to masturbate one more time right there surged up, but Kang Seo-ah barely managed to hold it back.
Putting her shorts back on and picking up her tablet, she cautiously approached the desk.
The monitor was already off.
Although it was a small amount—
On the desk, the white, cloudy fluid remained clearly, pooled like a small puddle.
The semen that Kang Si-woo hadn't noticed right away and had left behind without cleaning.
Her heart was beating like crazy.
'Th-that semen.'
Toward the defenseless semen, as if it had been left there for her—
Kang Seo-ah lowered her head and brought her tongue to it.
"...Lick♡"

The moment it touched the tip of her tongue.
The warm semen, which was still maintaining its heat not long after ejaculation, transmitted Kang Si-woo's taste to her brain through her tongue.
Kang Seo-ah closed her eyes, savored the taste, and licked the semen on the desk like a madwoman.
With the momentum to pierce through the desk with her tongue, she licked it passionately, trying not to miss a single drop.
'Oppa's taste... Oppa's...♡'
She was almost out of her mind.
But soon she realized reality.
Kang Si-woo would be back soon.
Kang Seo-ah licked the spot where the semen had been one last time and swallowed her regret.
She wanted to take the tissues Kang Si-woo used to catch the semen before he left, but she had no choice but to give up, thinking Kang Si-woo might notice right away.
She didn't delay any longer, quickly slipped out of the room, and returned to her own room.
The moment she closed the door and sat down on the bed, Kang Seo-ah savored the taste of Kang Si-woo that still remained in her mouth.
Not even breathing carelessly so that the thick taste lingering on her tongue wouldn't escape, she put her hand back inside her pants.
"Haa... Oppa...♡"
Kang Seo-ah closed her eyes, rolled the saliva mixed with the taste of semen remaining on her tongue inside her mouth, and started masturbating again.
"Phew..."
It felt like my head was a bit empty for the first time in a while.
Maybe because it had been a while, the amount was larger than usual, so I failed to catch it all with the tissue.
After roughly pulling up my pants, I came to the bathroom and washed my cock and hands clean.
Finally, washing my face with cold water made me feel very refreshed.
Tap-tap-tap-tap— Clack!
"...?"
While coming out of the bathroom and heading back to my room, I saw Kang Seo-ah hurriedly entering her room.
'Is there something urgent?'
She went in almost running, so I was a bit puzzled, but I thought she must have a reason and returned to my room.
Sitting back in my chair with a refreshed feeling, I didn't see the white, cloudy fluid I thought had splattered on the desk earlier.
"Tsk, I must have seen wrong."
I was worried it might have gotten on the printouts I had left on the desk, but it was a relief.
I threw the tissues that had finished their job into the trash can next to the desk and scanned my clothes.
"It didn't... spill on my clothes."
Fortunately again, there were no traces of it on my clothes either.
However, since I had just mopped, I felt a bit sticky, so I decided to take a shower.
When I opened the closet to grab underwear and a change of clothes—
"...What is this?"
On the floor of the closet where lots of clothes were hanging, an unknown liquid was pooled thickly.
It also seemed like a fragrant smell was coming from somewhere in the closet.
"Did water leak from somewhere? ...How could water leak from here?"
It was a very puzzling matter.
