Chapter 57: Sisters (5)
The house was blanketed in silence as Kang Yu-dam approached, humming a low tune.
She carried a shopping bag in her hand. Dressed for winter in a coat, sweater, and long skirt, her attire reflected both her status and her quiet anticipation.
Who was she kidding? Yu-dam knew today was Kang Yu-ri’s birthday, but part of her was expecting something more.
For instance, her younger brother Yu-jin’s admiration, his excitement, or those furtive, lust-filled glances he sometimes cast her way.
But she never let it show. She was the older sister, the eldest daughter, the protector, and the head of this household.
She simply harbored a secret wish. A wish to entwine her body with her brother’s, to howl and pant like a bitch beneath him.
And so, before entering the house, she paused to straighten her clothes.
She checked her sleeves, smoothed the layers under her coat, and, maintaining a soft smile, ensured there were no snags in her stockings.
She had prepared thoroughly so that today’s protagonist, Kang Yu-ri, wouldn't feel neglected. Taking a deep breath, she flipped up the cover of the digital door lock.
Following the cheerful melody of the keypad, she turned the handle and opened the door. A draft of air rushed out, but the house felt strangely desolate and still, causing Yu-dam to tilt her head in rare confusion.
‘The heating is off?’
Puzzled, she stepped inside, only to be greeted by a hollow, empty living room.
Yu-dam’s eyes widened slightly, and she blinked. Unable to immediately grasp the situation, she looked around as she kicked off her heels and walked further in.
“…Jin? Mini? Yuri?”
There was no answer. Straightening her head, her eyes meticulously scanned the room.
This building belonged to her.
Aside from the convenience store on the first floor, every inch of the building was a space dedicated to her family.
Considering the second and third floors were their living quarters, it wasn't necessarily strange for the living room to be empty.
Perhaps they were having the party on the third floor. Yu-dam tried desperately to convince herself of that, but a nagging feeling that something was wrong prickled at her. Her gaze shifted to the wide-open window.
She noticed the sofa, still damp from a recent wiping, and the cake sitting on the table.
They had clearly been eating and drinking here, not on the third floor. There were empty beer cans on the table to prove it.
Among the rolling cans, a chair had been pushed back unnaturally. Shoes were lined up at the entrance, but the indoor slippers were missing, as if everyone had left in a great hurry.
‘Maybe I should have checked the convenience store on my way up.’
Yu-dam tried to brush it off as nothing.
Perhaps, since it was Yuri’s birthday and her first time drinking, they had gotten excited and decided to go out.
Maybe someone had vomited on the sofa or spilled a drink, which would explain why the window was open.
Yu-dam smiled, struggling to interpret everything in a positive light. She maintained a warm, conscious expression while trying to calm her heart, which was beating with strange violence.
Her sharp mind was already analyzing and calculating the situation automatically, but her emotions fought to ignore the results.
The attempt was largely successful. She had always been a master of self-control, and a lifetime of ballet had pushed that discipline to its absolute peak.
Smiling, Yu-dam turned around, debating whether to check the third floor or head back down toward the convenience store.
“…Hm?”
That was when she saw something fallen beneath the sofa.
“This is…”
She reached out. Her long fingers snagged something—something incredibly squishy. As she straightened her back and lifted it, a chilling shiver raced down her spine.
Naturally, Yu-dam’s face hardened. Her fingers moved slowly against the squishy texture.
Slowly, as if savoring it. When her fingers pressed against the liquid inside, it parted to the sides; when she pulled away, it clung together with a viscous texture.
The gentle, kind expression that usually graced Yu-dam’s face vanished, replaced by a frigid mask.
It was the same cold, expressionless look she used to wear years ago during her ballet performances.
In her dark eyes, now colder than ice, the reflection of a pinkish, water-balloon-like object was clearly visible.
“…This.”
She had never used one. But she knew. She knew exactly what it was and what it was used for.
Though she lacked personal experience until recently, there was no way she wouldn't know. She hadn't lived such a sheltered life as to be ignorant of this.
She stared at the condom. It was a condom filled with semen.
She couldn't tell how old it was, but the lubricant on the outside had dried up. However, the amount inside could hardly be called small.
And somehow, it felt familiar. Yu-dam’s eyes trembled slightly. Her impulse to tear it open and verify its contents fought against her reason, which warned her it might be contaminated.
‘It’s semen, isn’t it?’
Even without checking, she knew. Yu-dam remembered the texture of the semen her brother had ejaculated onto her face, the taste of the warm cum he had let her swallow.
That texture. It was identical to what was inside this condom.
Even if it weren't, the identity of a milky-white fluid inside a condom was obvious.
If so, then why?
And how?
Yu-dam’s thoughts sank into a deep abyss, and a dark light flickered in her sunken eyes. A sense of possessiveness began to rear its head.
‘Mini?’
The two of them seemed to bicker, yet they were close. It wasn't rare for her to barge in while he was showering. In fact, it felt like it had been happening far too often lately.
‘Yuri?’
But that wasn't impossible either. Yu-jin had always loved and cherished his younger sister, so it was possible that accidental physical contact had escalated into the heat of a sexual encounter.
While her heart and mind were becoming a muddled, muddy mess, her ears caught the sound of approaching footsteps.
Her hands moved swiftly. She tossed the condom into her open handbag just as the sound of the door lock clicking open echoed through the hall.
The door swung open. The gloomy expression on her face vanished, replaced instantly by a bright smile.
“Oh, you’re back?”
She could always verify the truth later.
Darkness swirled within Yu-dam’s narrowed eyes.
I knew Noona would be coming home.
That’s why, after barely reaching the 100-mark and clearing several sub-quests, we had discussed our next moves outside while checking the rewards.
It was a decision made just in case time hadn't slowed down enough, and to add to that, Yuri had come up with a clever plan.
She suggested we go to the convenience store and buy a few things so that even if Noona came home while we were out, she wouldn't suspect anything.
I agreed, and Kang Yu-min… well, she doesn't really think, so she just went along with it.
It was basically a unanimous decision.
So, even after returning home, I acted as if nothing had happened, and Yuri did the same.
Kang Yu-min was clearly struggling to keep her cool and kept fidgeting, but…
“We ran into one of Kang Yu-min’s friends while we were out. She got totally roasted.”
“N-No, I didn't!”
“Please. You looked like a total loser…”
“Hey! Stooop!”
She got awkwardly angry, but it looked enough like her usual 'loser' self that it seemed we could pass it off.
And although Noona was sharp and quick-witted, she was someone who always placed deep trust in her family.
I thought I had successfully fooled her. Noona just smiled quietly and gave simple responses like, “Is that so?” which seemed to confirm my assumption.
What a relief.
I was worried about what would happen if she caught us, but she didn't.
So, we naturally celebrated Yuri’s birthday—playing, eating, and drinking.
Of course, it wasn't like there weren't problems to solve. We had only entwined our bodies as a temporary measure; it didn't mean our relationships were fully sorted out.
Above all, questions remained about Yuri’s true intentions and why Kang Yu-min had started liking me.
And there was the issue of how I should view the two of them and how I should accept all of this.
But at least for today, I wanted to stop worrying.
Ejaculating 100+ times had completely drained me. Even if my stamina in the game and reality were separate, the exhaustion was real.
It was mental fatigue. So, I drank, ate food and cake, laughed, chatted, and then prepared for bed.
We went up to the third floor, and after a quiet exchange of glances with Kang Yu-min, we washed up together.
“…Are we not going to do it anymore? I…”
“Sorry, I’m really exhausted. Remember that I got squeezed dry 100 times and show some mercy.”
“Fine…”
Kang Yu-min finally relented after I squished her cheeks like dough, and thanks to that, I was able to head to the bedroom without any further interruptions.
It was my bed—familiar yet somehow strange. Maybe it was because I’d spent days on a foreign mattress during those 100 ejaculations, constantly pounding away at Yu-min and Yuri.
I collapsed face-down on my bed and let out a long sigh. My mind was hazy from the alcohol, and despite having physical energy, my body wouldn't move properly due to mental exhaustion.
I was tired and sleepy.
Good. I’m going to sleep all day tomorrow. I’ll think of an excuse later.
I couldn't keep my eyelids open any longer and closed my eyes.
Creeeeeak.
I snapped my eyes open at the sound of a door opening with terrifying slowness.
I turned my head. It was too dark to see clearly, but a long shadow and a curvaceous body were faintly silhouetted by the moonlight and city lights.
“…Noona?”
I couldn't see her face. It felt as if a shadow itself were standing there, looking down at me. I swallowed hard instinctively, and Noona’s body slowly approached.
“It’s you, Noona… right?”
It was eerie. As she drew closer in silence, her signature scent mixed with the smell of alcohol wafted over me.
It was so distinct there was no mistaking it. I blinked, trying to see her, but her hand reached me first.
Then, Noona’s body embraced me. As if possessed by some intangible force I couldn't resist, my body was flipped over by her touch.
Her hand immediately slid into my pants and began stroking my cock.
“Wa-wait. Noona… I’m really tired…!”
Noona didn't answer. Because I couldn't see her, a creeping fear began to bloom. Despite that, her soft touch made me erect, and she began to stroke me up and down with a merciless rhythm, as if intent on squeezing every drop of semen out of me.
I let out a ragged breath, helplessly ejaculating from the continuous stimulation.
My body, which had stiffened with a jolt, shivered as I soiled the inside of my pants. Why? I looked at Noona in bewilderment, and only then did her eyes meet mine.
Her eyes were filled with a coldness I had never seen before.
“Noo-Noona? Why—”
“It’s watery.”
It was a voice so cold it felt like it could freeze my very soul. I didn't know she was capable of sounding like that.
Yet, for a moment, she reminded me of Mother.
Caught between the familiar and the alien, I couldn't even breathe properly. I simply stared at her eyes, which seemed to glow in the darkness.
Noona quietly looked down at me while licking the semen off her hand.
In that moment, alongside the terror, I felt a faint surge of arousal. It was an emotion I couldn't even understand myself.
