Chapter 24: Reward (4) ♥
Chapter 24: Reward (4) ♥
Was it because of the sense of depravity? I let out a groan as a searing heat surged from my waist, up my spine, and into my head.
It felt as if my lower back was giving out. My skin crawled, and a tingling sensation spread to the very roots of my hair. I could barely manage to catch my breath amidst the overwhelming haze.
“Ugh, ahh….”
Fortunately, I wasn't the only one. Kang Yu-min was also letting out similar moans, swept away by the lingering afterglow of her climax.
Only a small part of us remained in contact. I was practically lying down, while Kang Yu-min was mounted on top of me, her upper body arched back and her head tilted high, her entire frame trembling.
We simply stayed there, struggling to steady our ragged breathing while gasping in the wake of the orgasm.
Only my cock twitched inside Kang Yu-min’s pussy, pumping out semen. She panted heavily, as if she could feel my cum filling the condom.
It was a long while after the ejaculation ended—or at least, it felt like a long time—before we finally regained our senses.
As the rush of blood to my head subsided, I found myself looking down.
“Ngh, again…?”
Yu-min asked in a dazed, slurred voice, sounding flustered. Just as she said, my cock had hardened once more, standing stiff.
It made sense. My cock, though covered by a condom, was inside my biological sister’s pussy. I couldn't even use the excuse that this was just a game anymore.
Inwardly, I had thought that excuse was for my eldest noona, but that wasn't entirely true.
It was an excuse for myself as well. Realizing that anew, a wave of depravity washed over me.
Born from the same womb, fashioned from the same seed—we were undeniably siblings.
The same blood flowed through us; we were clear kin with nearly identical DNA.
This was an act that society would never tolerate. An act that deserved condemnation from anyone who saw it.
Perhaps that was why I was getting so aroused amidst this unimaginable sense of depravity.
The fact that I had broken a clear social taboo with my own hands—and was still breaking it—while my cock squeezed out semen inside Kang Yu-min’s pussy.
If there were no contraception, no condom, what would happen next was obvious. Yu-min’s belly would swell, and we would have to become a couple as well as siblings.
And what about the child born from that womb? The thought of it made my testicles boil with excitement even before any realistic worries could set in.
My cock grew even stiffer. It became so hard I wondered if it had ever been this erect before, thumping against Yu-min’s uterus with a dull thud.
Yu-min seemed unfamiliar with the sensation, grimacing at the foreign feeling, yet she was already dripping with pussy juice.
“Ehehe, h-aaah… Ah, ahh!”
Soon, she began to move her hips slowly. Even though I had just ejaculated, I was helpless against the stimulation she provided.
With our bodies arched back or lying down, we moved together, joined only by our lower halves.
Through the thin layer of the condom, I felt the clingy pussy meat tightening around me and the decadent pleasure of her internal warmth.
I could feel that the inside of the condom was filled with semen. Beyond the pussy meat wrapping around my cock, my own cum was soaking me from within the latex.
It wouldn't have been strange to worry about it leaking, but Yu-min didn't have the luxury to care about such things.
She simply moved her hips busily.
Up and down, then, as if she were getting tired, she began to grind her hips back and forth.
Her waist seemed to ripple with the movement. It was a supple motion befitting her flexible body. I watched her lewd display in a daze, savoring it.
“…Does Noona’s pussy feel good?”
The question was suddenly directed at me. When I reflexively nodded, Yu-min gave a silly grin.
“You… pervert….”
Squish, squelch, slurp. The sound of her pussy juice was incredibly sticky. The sound of our skin friction felt loud in the quiet room.
“It feels good for me too, but….”
She was being unusually honest. It was a candid and lovely way of acting, unlike the Yu-min who was always full of bravado. I swallowed hard, feeling the blood rush to my cock, while Yu-min panted, moving her hips back and forth.
“Ngh, ah… You’re hitting all the right spots… I feel like I’m going crazy…!”
I felt the same. The pussy meat tightening around me was intensely stimulating in its own right.
Mentally, I certainly wasn't a virgin. I had already done it with my eldest noona inside the family-friendly game—which, despite being a game, felt closer to reality.
But regardless of that, this wasn't that reality. In this reality, I was a virgin, and until moments ago, I definitely had no experience.
To think I would lose that experience to my own sister. As I reached out to grab Yu-min’s thighs, she braced herself by leaning back on both hands and moved her hips even more fervently.
“Ugh, haah, if I had known… it would be like this…!”
She stopped mid-sentence, gasping. As I stiffened my body at the sensation of her pussy meat tightening to an almost painful degree, Yu-min trembled and dropped her head.
“I should have done it… sooner.”
Yu-min let the words slip in a somewhat exhausted voice.
The woman who was my second noona reached a climax from my cock, and then, as if the strength had left her waist, she wriggled and pulled away.
My cock, which had been filling her pussy, was revealed. A condom-clad cock dripping with pussy juice.
Inside that condom, the semen was spread thick and white. A clear mark of ejaculation.
However, I couldn't help but look at Yu-min with a dissatisfied expression.
I hadn't finished yet. You’re going to get me all worked up and then just leave me like this?
Yu-min read my gaze and gave a playful smirk.
“My back hurts.”
“And?”
“You do it.”
“…Huh?”
Yu-min lay back. If she had just laid there, I might have smacked her butt.
But I couldn't do that when I saw her spreading herself open. She lifted her legs and pried her pussy open with both hands, making it gape.
Her pussy was slick and glistening, soaked in fluids. I gulped.
The line had already been crossed. And contrary to the thought that everything would fall apart once we crossed it, almost nothing had changed.
I had simply become honest with my desires, and since I had already done it with Yu-min, I felt there was no need to back out now.
So, I tried to take out a new condom, but…
“Ah.”
“Uh, what?”
“Hey, you have contraception turned on, right?”
Yu-min had already checked the rewards I had received earlier. At her words, I picked up my smartphone to check.
[Automatic Contraception]
[ON]
“Yeah, it’s on….”
“Then, you know….”
Her voice sounded thick with heat. Yu-min hesitated for a moment before whispering with a smile.
“Do you want to try putting the condom on inside out?”
Did I hear that right? As I stared blankly, Yu-min whispered again, her face turning even redder.
“I want you to… smear your semen all over the inside of my pussy….”
“…You perverted girl….”
“Wh-what do you mean, calling your noona a pervert! Y-you’re turned on too, aren’t you?”
Her stuttering words were undeniably true, much as I didn't want to admit it. My cock was swelling and throbbing even more.
And it was something worth being turned on by. Just imagining a creampie made me feel like my cock was going to explode, but to take the semen already collected in the condom—the very tool meant for contraception—and flip it inside out?
To smear the semen that had filled the inside back onto her? It was inefficient and made no sense.
But on the other hand, it was incredibly hot. It felt like the tool for contraception was becoming a tool for conception.
I hesitated for a moment before grabbing the condom.
As I gripped the tip, I felt the semen inside start to flow back. The cum coated the shaft and soaked down to the base.
As I gripped the condom, slick with pussy juice, and slowly pulled it off, the semen was dragged out and smeared over my cock.
Once it was completely off, the condom was in no state to be put back on. How was I supposed to flip this? I was pondering this when she spoke.
“There’s so much semen on it… Should I clean it for you?”
“With your mouth?”
“No, th-that, heehee….”
“What? What’s with that creepy laugh?”
“Do you want to… wipe it off by putting it in my pussy?”
I flinched. Those words were beyond stimulating.
I wasn't sure if I could stop at just "wiping." Yu-min seemed to know this as well, as she bit her lip for a moment before adding:
“Wipe it with my pussy… and once the condom is clean… I’ll let you put it in without one.”
It was an incredibly tempting offer. I gulped and looked at my cock, which was dripping with semen.
It wasn't enough. There was more semen left inside the condom. Unable to hold back, I slowly flipped the condom while pressing my hips forward.
Yu-min let out a moan, and without even focusing on the condom, I simply held it in my hand and thrust my cock as deep as it could go.
“H-ah, ugh….”
Amidst the moans escaping my own lips, I felt Yu-min’s pussy vividly.
The pussy meat tightening elastically, the pussy juice overflowing, and the uterus that seemed to twitch every time I thudded against it.
I couldn't tell if it was the pussy meat or the uterus twitching, but it was just as Yu-min said.
Her pussy was already so wet that it could wash away the semen.
Every time I moved my hips back and forth, the semen flowing down the shaft and base was washed by her fluids and sent toward her womb. As I felt that, a sudden thought occurred to me.
What would happen if I poured my semen into her womb like this and then turned off the contraception?
Would Yu-min get pregnant immediately? Or would there be a slim chance of it missing?
I remembered that semen could stay inside the uterus for a long time; what would happen if I turned it off halfway through?
It was a chilling thought. A shiver ran down my spine, and I found myself breathless.
The urge to ejaculate surged rapidly. Even as I felt the reality that I shouldn't do it—that it would ruin my life—I felt a sudden, overwhelming desire to do exactly that.
A feeling of wanting to throw everything away for the pleasure of the moment.
A trace of depravity and guilt mixed together, sticking to my sexual desire like sludge.
I couldn't suppress that impulse. The speed of my thrusts increased, and Yu-min’s eyes widened as she saw me stop trying to flip the condom and instead press down on her thighs. She let out a vulgar moan.
And as she lay there, she simply panted and accepted my raw cock without resistance.
Squish, squelch, thud. The sounds of our fluids mixing and our flesh colliding filled the air.
While our mixed body fluids soaked the bedsheets, I fought against the impulse.
I wanted to bury it to the base and blow. Amidst the conflict between that impulse and the desire to do what I was supposed to do…
Before I knew it, I opened my mouth and spoke.
“I think… I’m going to cum…!”
My eyes met Yu-min’s as she gasped. Yu-min, panting behind her dark pupils, looked so fragile and beautiful that it was hard to believe she was my sister.
“You shouldn’t… cum inside—”
Ignoring even those words, I reflexively pushed my body forward and pressed my glans firmly against her cervix.
At the point where my glans kissed her womb, Yu-min let out a sharp, hitched breath and panted.
I said, “I’m cumming inside, so squeeze…!”
Yu-min bit her lip hard.
And as she tightened her pussy with all her might, preparing her womb to receive the semen…
I ejaculated right then and there.
An intense pleasure that was more than enough to bleach my mind white. Holding the condom in my left hand, I panted and pressed my cock deep to stimulate her womb. Yu-min twisted her head and curled her toes at the sensation of her uterus being pressed.
And it wasn't just her toes. Her hands covered her face and gripped the bedsheets. Whether she had reached a climax from the creampie or not, all ten of her toes repeatedly curled and uncurled.
My head felt fuzzy from the intense pleasure and sense of depravity. Only the instinct to ejaculate and the urge to get this woman pregnant remained, fanning my flames. My smartphone caught my eye.
In the midst of an impulse that felt like it would stop my heart, I reached out with a trembling hand…
But I barely managed to suppress it and looked at Yu-min instead.
With tears in her eyes, her expression was melted with an emotion similar to, yet different from, the time I had pushed her and made her cry.
The woman who was my second noona didn't even remove the hand covering her mouth as she wept.
“…Are you going to… take responsibility?!”
Yu-min stopped mid-sentence, her waist stiffening. Feeling her pussy filled to the brim, Yu-min’s eyes widened before she snapped her head away.
The fact that she slightly spread her legs further was a bonus.
“…You perverted bastard, cumming in your own sister’s womb.”
Was that something the person who told me to wipe the cum off with her pussy should be saying?
That was my immediate thought, but I didn't yield to her unreasonable accusation and began moving my hips again.
After all, Yu-min was weak for my cock.
