Chapter 8: Bad Friends (3) ♥
Chapter 8: Bad Friends (3) ♥
“You pervert…”
The reproach, delivered through tear-filled eyes, consisted of words I couldn't possibly refute.
After all, looking at the current situation, there was no room for doubt, was there?
Knowing that, I had no choice but to squeeze my eyes shut.
But closing my eyes didn't make everything magically resolve itself. For one, I wasn't an ostrich, so I couldn't just believe the world had disappeared.
Still, I had to keep them closed. I needed to organize my thoughts and somehow dampen this arousal.
Not that it would make the situation any better.
“G-getting hard for your own sister… are you actually insane?”
Her voice trembled. It was moist, laced with a hint of tears.
To me, it was inevitably provocative. My body, already heated up because of Eldest Noona, refused to listen to my mind.
Of course, getting an erection or having it subside wasn't exactly a matter of will, but still.
I had a certain set of beliefs—a sense of pride, if you will.
As the only male among the four siblings, I took pride in the fact that I had almost never been aroused by my family.
That pride was crumbling. I bit my lip, eyes still closed, as I felt her breath so close to me inside the cabinet.
“Did you… earn money doing stuff like this?”
The sudden question forced a response out of me.
“No, I didn't…”
“Then what?”
“Usually, it was stuff like getting twenty headshots or surviving for fifty days.”
“Then what is this?”
Her voice carried a strange heat. I tried to tell myself I was imagining it, but there was a peculiar vibe in her following words.
“Is this your subconscious? Doing… that kind of thing with your sister?”
“No, why would that be my subconscious? It could be yours, couldn't it?”
“…There’s no way my subconscious would want that filthy stuff poured into my mou—”
Thud!
A loud boom cut her off. Kang Yu-min and I stopped talking as if we’d rehearsed it, staring at the rattling door.
Perhaps we had been talking too loudly; the ‘monster’ had returned and was pounding on the door.
It felt like a neighbor throwing a fit over floor noise. But the terror of being caught was incomparable to that.
I naturally fell silent and met the gaze staring blankly at me.
“…Pervert.”
Kang Yu-min’s gaze drifted downward. It fixed right on my crotch.
If I’d known this would happen, I would have worn jeans. The cotton pants I was wearing were thin, making the shape of my erection stand out prominently.
Beneath that thin fabric, my member throbbed, pressing against Kang Yu-min’s abdomen. It pushed against her navel as if stimulating something hidden beneath.
The space was cramped, and two people inside were forced into intimate contact.
I held my breath, wondering if I should have hidden somewhere else.
“Look, let’s just call this an accident for now…”
That was until Kang Yu-min’s body suddenly lowered.
My eyes widened. Her face was now level with my crotch.
“W-wait! What are you…”
“Be quiet. I… I don’t want to do this either, but…”
Kang Yu-min’s eyes darted around. I didn't have to ask to know what was reflected in that gaze staring into the empty corner.
2,500,000 won was a significant amount of money.
“I… I need the money too.”
“No, Eldest Noona brings home plenty of money, so why…”
“Anyway! I can’t let you be the only one earning, and they said it goes to both of us anyway!”
She was the one who told me to be quiet. At the sound of the door being pounded, Yu-min flinched, her shoulders hunching before she let out a breath.
“Anyway, yeah, right. It’s just a game, isn't it? It’s not reality… why be so serious? Just…”
Muttering to herself, Yu-min reached for my waistband.
She was too close to block. In an environment where it was difficult even to lower my arms, Yu-min pulled my pants down as if to show me.
No, perhaps.
Perhaps I agreed with her words. It was just a game, after all.
No matter what happened here, nothing would happen in reality, right?
If the partner was Kang Yu-min, wouldn't it be okay?
We were siblings, but we were also ‘bad friends.’
It wasn't strange for us to know each other’s sordid tastes, and sharing a hobby shouldn't be that difficult.
I suddenly thought of my friends who had brothers.
Some of them even shared porn with their siblings.
If I considered this a part of that…
It was then. I flinched at the sudden sense of exposure.
“Hiek.”
Naturally, my thoughts stopped at the sound of her voice. Looking down, I saw my familiar member, the one I saw every day.
If it had just been that, it might have been fine.
“It’s… huge…”
Yu-min clamped her mouth shut as if realizing her slip of the tongue.
Even that look seemed cute to me.
I’m losing my mind, seriously.
I was even becoming hopelessly aroused by the fact that my erect cock was right in front of Kang Yu-min’s face.
Wait, why is this a turn-on? This shouldn't be happening, right?
My common sense was clashing with the situation. I tried to focus and calm down, but it wasn't working.
“Stop messing around and pull my pants up…!”
Yu-min didn't listen. Her breath was gradually growing hotter. As if debating what to do, her lips hovered right in front of my cock.
I froze. When I opened my tightly shut eyes, I saw Yu-min with a slightly mocking, smirk-like expression.
When she kept her mouth shut and stayed quiet, her face was chic and beautiful.
Her cat-like, sharp yet cute eyes.
And her lips, moist and exhaling hot breath, were seared into my vision and mind.
Naturally, my lower body twitched. At the pulsing shaft, Yu-min unconsciously swallowed her saliva.
“H-how do I do this?”
“…What?”
“I… I don’t know how to do this…”
There was a certain sexiness in her weak voice.
Huff, huff. The hot air she exhaled was a good stimulus, but it was only a stimulus.
It wasn't the deciding factor. Therefore, the act that inevitably followed was predictable.
The problem was that Yu-min knew nothing about such things. She looked up at me with trembling eyes, her fidgeting hands clutching my shirt.
“Are you… are you really going to do it? No, even so…”
“I’m, well, the older sister. If you’re in trouble… I have to do something about it.”
But surely not this far? As I stood there dazed, Yu-min furrowed her brows.
“Coward.”
She cornered me with that one word.
“You’re the one who got hard because of me anyway.”
“No, that’s—?!”
I was forced to stop mid-sentence. Because Yu-min’s long tongue, extended far out of her mouth, licked my glans.
It was a sensation I had never experienced before. It certainly wasn't as efficient as my hand, a tool I used often.
But this had a different kind of stability.
A comfortable, warm, and pleasant sensation.
It was a different kind of pleasure than the one that leads to ejaculation. I stared down, dazed, processing what had just happened.
Yu-min looked up at me, checking my reaction, and then licked the glans again with her long tongue.
Like a cat lapping up milk.
“…Ith ith ood?”
Yu-min asked if it felt good. Her pronunciation was distorted because of her extended tongue, but the meaning was clear.
I nodded unconsciously, and Yu-min’s eyes crinkled into a smile.
That smile.
I remembered a time when a friend asked if I could introduce him to my sister, wanting to meet Kang Yu-min.
Yu-min had a slightly dorky side, but combined with her looks, it tended to trigger a protective instinct.
Yu-min’s friends often spent time with her for that reason, and every time, she would show that eye-smile that melted both men and women alike.
The way her eyes folded as she laughed with genuine joy was something else. In that moment, she was almost on par with Eldest Noona.
For that reason, I stayed still, unable to stop her. Inside the narrow cabinet, there was only the sound of Yu-min licking my cock.
The sound of heated breaths, the faint sound left behind as her tongue swept over me.
Normally it wouldn't be heard, but because it was so quiet, it sounded vivid. The cramped cabinet only amplified it.
Her tongue, more than warm—hot—licked the glans. After licking it as if wiping it clean, she pointedly moved down to lick the shaft.
I could clearly feel the trail her tongue left behind. A mark stained with saliva, heat, and lust.
I groaned at the sensation but kept looking down at her.
Yu-min wasn't even checking my reaction anymore. She just closed her eyes as if possessed, focusing on licking my cock while panting softly.
…It was teasing.
Part of me wanted to take the lesser of two evils—use my hand to stimulate myself and just finish in her mouth—but the cabinet was too small.
Was this really okay? Wouldn't this be betraying Eldest Noona?
Or was it right to just brush it off because it was a game?
Would this have a huge impact on our psyches and change our relationship forever?
They called it a family-friendly game. Is this really friendly?
After all sorts of thoughts flashed through my mind, I was about to suggest that it would be better if I just handled it myself and finished in her mouth.
“Kang Yu-min, that’s enough…”
So I quietly called her name.
Up until then, it was certain that I still possessed some reason.
If only Yu-min hadn't licked the glans with her long tongue the moment her name was called.
Mwah.
And if she hadn't kissed the spot she had just licked.
“…Whay?”
I felt something inside me crumble.
Yu-min’s eyes went wide. I don't know what she saw, but a faint smile seemed to brush across her flushed face.
But I didn't have the luxury to worry about that. My painfully erect cock poked her cheek, and Yu-min fidgeted with her lips despite her bewilderment.
Yu-min knew what was about to happen. Perhaps she did it knowing full well.
Women have sexual desires too, after all.
“Put it in your mouth.”
Yu-min gave a playful smile. Her smiling face was truly top-tier.
“…Okay.”
A rare, submissive answer. Yu-min opened her mouth and bit down on my glans.
“Ah…”
A sense of relief washed over me. Pleasure surged through the glans. As my hips trembled slightly, Yu-min used her tongue to lick the glans while keeping it in her mouth.
It felt good. The sensation of her hot mouth enveloping the entire head was incredible.
But it wasn't enough to make me ejaculate. Leaning against the cabinet wall, I let out a ragged breath and said,
“Pucker your lips and… can you suck it?”
Without a word, Yu-min immediately put it into action.
“Ugh, too hard. Relax a bit more, yeah… like you’re using a straw…”
Yu-min adjusted her suction accordingly, being considerate of my pleasure.
“It would be good if you licked it with your tongue occasionally. Ah, yeah. Like that.”
Her previously still tongue moved clumsily, licking away, and I even let out a faint moan at the sensation.
“Move your head. Take it deeper, and repeat pulling it out and putting it in…”
And as the ‘stimulation’ began in earnest, I closed my eyes.
There was no other way for me to endure it. The approaching stimulation was intense.
Kang Yu-min, the sister I had been bickering with as a nemesis until just a moment ago, was taking my cock in her mouth.
Not only that, she was sucking it with a gentle expression and attitude. In fact, she was sucking it while adjusting the intensity as if she were enjoying it herself.
As I well knew, Yu-min was definitely a beauty.
So just looking down at her face as she sucked intently triggered a reaction in my body.
The spilled saliva flowed past my waistband and soiled Yu-min’s chest. Her soaking breasts became more prominent. I gulped at the sight.
It was already provocative because she was wearing a sleeveless top that revealed her cleavage.
And unfortunately, the sound of me swallowing was clearly audible in the cramped cabinet.
Even amidst the slurp, suck sounds of her sucking, it was a sound that couldn't be ignored. Yu-min, who had her eyes closed, opened them and glanced up at me.
Following my gaze, she looked down and then gave an eye-smile, moving only the corners of her eyes.
Her sleeveless top rode up. As I froze, her breasts were revealed.
My hips twitched, and Yu-min smiled and closed her eyes again.
Yu-min’s breasts were certainly not as large as Eldest Noona’s.
But those breasts had their own charm.
In terms of shape and physique, it felt better than just having something huge attached.
And they were by no means small. Yu-min’s breasts were larger than the average woman’s, after all.
Breathing heavily, I looked at Yu-min, who had somehow taken my hand.
She guided my hand and placed it on her head. As I stared blankly, Yu-min puffed out her cheeks slightly as if pouting.
“Stroke it. Hurry.”
Then she took my cock back into her mouth. At her head diving deep, I barely swallowed a breath that was about to escape and stroked her hair.
It felt different from Eldest Noona. The heat spread evenly across her scalp was hot.
Eldest Noona’s hair had a cool feel to it, but maybe it was because Yu-min’s hair was shorter.
The sensation of touching it was good. I stroked Yu-min’s head while staring at her exposed breasts.
Yu-min wasn't just staying still while I gently stroked her head.
She caressed my cock with her tongue and mouth as if playing along.
The sound of her saliva-drenched mouth pleasuring me echoed dizzily through my head and body. I felt the sensation of impending ejaculation swelling like something uncontrollable.
Something I had never experienced in my life. It was already surging up to my throat.
“Ugh, Yu-min. It’s almost…”
Even Yu-min, who hadn't even known how to do it, seemed to know what was coming. While her sharp eyes melted into a thick gaze staring at me.
“Ugh…?!”
Yu-min took my cock even deeper into her mouth. All the way to the root.
She didn't stop there. She pulled on my hand that was resting on her head. Her desire was clear, and I couldn't stop her.
Rather, I should say I complied and acted accordingly.
I knew for sure this would feel good. So there wasn't even any hesitation.
I simply pressed down firmly on Yu-min’s head.
Naturally, I exhaled as I felt the glans hit the back of her throat.
And Yu-min, without a word of complaint, incessantly swallowed the semen that burst out along the urethra.
Even though she probably couldn't even breathe with me pressing down on her head.
[Ejaculate 10ml of semen into Second Noona Kang Yu-min’s oral cavity. 8/10ml]
[Reward: 2,500,000 Won Cash]
The amount was not normal. It was a staggering amount that made me look back and wonder if I had ever ejaculated this much in my life.
It felt that way physically, and the quest appearing before my eyes confirmed it.
They say the average human ejaculation volume is 3–6ml, but the amount I just ejaculated was nearly double to 1.3 times the average.
And even then, it was only 8ml. I let out a long breath and trembled slightly as I emerged from the intense pleasure.
It was a long ejaculation. As I panted, Yu-min slowly pulled her mouth away from my cock.
“Phew…”
And I inadvertently dropped my head, only to get hard again.
“Ah.”
I saw Yu-min’s face and body.
A face melted by shortness of breath, pleasure, and some dark impulse I couldn't understand.
With that expression, I saw her tongue sticking out and the semen I had vomited inside her mouth.
The semen had gone past her mouth and was also splattered on her fully exposed breasts, and her breasts, wet with saliva and semen, glistened as a visual stimulus.
A sight I couldn't endure even knowing she was my sister.
No, rather, a sight I couldn't endure because I knew she was my sister.
I swallowed hard.
Her face stained sticky, and her mouth even stickier.
Yu-min’s eyes went wide when she saw my cock, which had become stiff again before she could even swallow the semen.
‘Pervert.’
A provocation drawn only with the shape of her mouth, her expression melted. I felt several things welling up inside me simultaneously.
I grabbed her head, and though she might have trembled in fear, Yu-min didn't seem to mind, giving a sly eye-smile before closing her eyes and opening her mouth.
A mouth sticky with semen and saliva. At the sight of her even tilting her head to make it easier for me to use, I grit my teeth and thrust my hips forward.
A muffled ugh sound was heard. The sound of her throat being poked. I saw tears welling up in her tightly shut eyes.
But I couldn't stop. I was already being driven by instinct and lust, beyond the reason I had let go of.
I simply grabbed Yu-min’s head, pulled it back, and thrust my hips again before she could hit the cabinet wall.
Every time I did, I heard sounds like groans and gagging that bordered on screams, but I didn't care.
Squish, suck, squelch—the lewd sounds filled my ears. I used Kang Yu-min, my older sister and my closest ‘bad friend,’ however I pleased.
By the time my testicles were thumping against her breasts and I realized the panting Yu-min was barely holding onto my waist with her trembling hands without stopping.
I was thinking only of ejaculating a mouthful into that throat.
Yu-min, whom I had never once thought of as hot, looked erotic. I knew that after this, I wouldn't be able to look at her with normal eyes, nor would I be able to walk into the bathroom knowing she was bathing.
I knew our relationship would never be the same.
A game? Let’s just call it a game and move on?
I knew it wouldn't be like that. But I couldn't stop.
Even Yu-min didn't want to stop.
So I did exactly what my desire told me to do.
“Ugh, ack, gack, slurp, slurp.”
While Yu-min repeatedly gagged and sucked as best she could, I thrust my hips with everything I had and shouted through gritted teeth.
“I’m coming. Swallow it all…!”
Her throat tightened. Her fallen tears soaked my abdomen. As I pushed as deep as possible, I heard a boiling sound from inside her throat as if she were about to gag.
The throat, tightening due to the lack of breath, felt good. The image of Yu-min crying her eyes out after I pushed her away flashed through my mind unconsciously.
Did I really feel nothing at the sight of her shedding those tears?
Perhaps, just a little.
Had I thought that I wanted to see that again?
The question I threw at myself yielded no answer. All that came out was the sticky, dirty fruit of lust that I could never normally vomit into my older sister.
[Ejaculate 10ml of semen into Second Noona Kang Yu-min’s oral cavity. 18/10ml]
[Reward: 2,500,000 Won Cash]
[!Overachieved!]
[Additional Reward: 300,000 Won Cash]
An even larger amount of semen than before. I panted, exhaling a long breath amidst a sense of exhaustion that felt like my waist was falling off.
It was an ejaculation as long as the volume. I held Yu-min’s head for a long time before letting go.
“Cough, cough, cough!”
The moment I let go of her head, Yu-min backed away, gagging and coughing.
Even so, not much semen came out of her mouth. Rather, only about 1ml of semen soaked Yu-min’s chest.
Which meant the remaining 17ml or so…
I leaned against the cabinet wall, breathing shallowly, and Yu-min finally raised her head after coughing for a long time.
“I almost… died. You pervert.”
A gaze that had melted and turned sticky. Tears welled up and trickled down, but looking at Yu-min, I remembered one fact.
In the not-so-distant past, Yu-min, who had cried after being pushed by me, had later claimed her tears were due to emotional pain.
I had thought she was just making an excuse, but perhaps.
Perhaps that was the truth.
Rather, perhaps Yu-min enjoyed the pain.
So I unconsciously dropped my gaze to the floor of the cabinet.
There, besides semen and saliva, was an unfamiliar liquid.
A liquid that seemed to have flowed out from beyond her soaked dolphin shorts.
It was clearly her pussy fluid.
