Chapter 25: Reward (5)♥
Chapter 25: Reward (5)♥
A wet, squelching sound echoed. It might have been my imagination, but it wouldn't have been strange if it were real.
The semen filling her pussy, the mixture of fluids already smeared and sticky on my cock—all of it was packed inside Kang Yu-min. With every movement I made, it sloshed back and forth.
Kang Yu-min panted, letting out moans that were as lewd as they were delicate and lovely. Even though she knew exactly what was happening, she showed no intention of blocking or stopping me.
I wasn't even sure if she had the mental capacity to try. Entranced, I kept thrusting my hips.
Every time my cock pushed forward, parting the vaginal walls and scraping the ribbed interior with my shaft and head, a high-pitched moan burst from her lips.
Holding both of her wrists, I pulled my hips back. Perhaps due to her toned muscles, I could see her pussy meat clinging to me, thick and syrupy.
It was as if her insides were being dragged out along with my cock. The way she squeezed and tightened around me was far too skillful for a virgin.
But if I were to wonder if this wasn't her first time, the answer was a definite no.
Even if she wouldn't admit it herself, Kang Yu-min was a total loner.
Her appearance and image had been the same back in high school. But because of her lack of social skills, she was only ever relaxed around family; usually, she found it difficult even to have a proper conversation with people.
That chic, cool image of hers was born from that. It helped that it suited her looks, but it was mostly her attitude.
She spoke little and kept her reactions brief.
Her social life wasn't bad, but that was entirely thanks to her cool demeanor blending well with her pretty face.
I knew that side of Kang Yu-min well. It wasn't that she never received confessions, but she never accepted them. Her reason was always that it was "scary."
There was no way a girl like that had any experience. I became certain when I saw the blood on the condom. It was very faint and mixed with semen, making the amount small, but it was there.
Siblings, exchanging their firsts with each other.
Creampieing her like this without a single worry about contraception, thrusting my hips so aggressively.
Despite the reality that there was no actual risk of pregnancy, those two facts provided a profound sense of depravity.
That depravity transformed into pure arousal. It made my cock rock-hard. Even though I had just ejaculated and my head was throbbing with exhaustion, my libido pushed me forward. I moved my hips back and forth without rest.
"Ah, ugh, hng, ahh...!"
Her moans were laced with a sweet, coquettish charm—a voice she surely wasn't making on purpose. I gripped both of Yu-min's wrists and pressed my body down so her thighs couldn't close, pounding against her uterus.
This was a space that should never have been permitted to me. This virginity and this womb were things that Kang Yu-min should have given to some "good man" she met in the distant future.
And yet, I was painting both of them in my own color. That fact gave me an irredeemable level of excitement.
I could feel the blood pounding in my temples. My breath grew ragged, but even as I gasped for air, I moved my hips as if possessed.
The way her pussy meat wrapped around my cock was distinctly different from Eldest Noona.
Unlike our eldest sister, who had stopped exercising long ago, Kang Yu-min’s pussy felt active.
It didn't just wrap and squeeze. It tightened in sync with my movements, to the point where I hallucinated that her insides were squirming with pleasure.
When I pulled out, she squeezed tight as if reluctant to let go; when I thrust in, she loosened for a moment, only to tighten firmly around the entrance when I hit her uterus.
With the rhythmic tightening matching my rhythmic movements, I felt the urge to ejaculate again almost immediately.
I’m going to blow. I want to dump it all into her uterus just like this. No, that’s not enough.
The thought suddenly flashed through my mind: I want to cum inside her and get her pregnant.
I knew I shouldn't, that it would completely ruin our lives.
But the desire inside me urged me on. My hand reached toward the smartphone several times, but I stopped myself.
Instead, I balled my hands into fists and pressed my hips down firmly, crushing against her cervix.
Her pussy meat tightened agonizingly around my pinned cock, and I let out a groan as a powerful wave of release surged from my waist to the top of my head.
I’m cumming. Even more this time.
But I couldn't even find the words to say it. Without the capacity to worry about Yu-min's state or my own well-being, I pressed my glans against her cervix and ejaculated.
"Ah, ugh, uuuugh."
Amidst a moan that sounded like a final gasp, the semen poured out. It filled her uterus, and the excess overflowed to fill her pussy.
If it weren't for the new options I'd gained, I would have moved past worrying about pregnancy and started thinking of baby names. Knowing that, I let out a deep, heavy breath and collapsed on top of Yu-min.
The moan she let out, which sounded almost like a sob, was sweet. When I turned my head to look at her, Yu-min was crying and smiling at the same time, even though her disheveled hair covered her eyes.
Panting, crying, and repeating over and over that she had come, Yu-min’s body trembled violently. I buried my nose in the crook of her neck and moved my hips in small, shallow twitches.
I had definitely finished. Along with a dull fatigue and a sense of depletion, there was even a slight hint of pain.
Since her pussy kept squeezing every time I moved, it wasn't strange for the overstimulation to feel painful.
But her pussy felt so good that I kept moving my hips despite the discomfort.
No, it wasn't just that. The simple fact that I was doing this with Kang Yu-min was an aphrodisiac in itself.
"Did you... cum?"
"A lot."
"Did it feel good...?"
Her languid voice was incredibly erotic. Was it because I was still moving? I nodded and pressed my hips deep.
"Yeah... Hey, stop playing with my pussy... and answer me..."
Was she feeling lonely? Come to think of it, I’d heard that women value conversation and connection after sex.
I’d even heard of people getting divorced because their partner didn't do that.
...Wait, it's not like we're a married couple, though?
Amidst the various thoughts popping up, I felt a soft tapping on my forearm.
"Hmm? Answer me..."
"It felt good. Really good."
"I-is that so? How was it...?"
Did she really want to hear a review of her own pussy that badly? I wondered, but I couldn't see her face clearly.
I just kept my hips squirming and, listening to her sweet moans, I put my thoughts into words.
"First... it was incredibly tight and hot, so that felt great."
"And?"
"It was fun how the way you squeezed changed to match my movements."
"What do you mean 'fun' when talking about your sister's pussy... ah, hey..."
"Should I say it was hot instead?"
She went quiet. I could feel her breath getting hotter.
"Yeah... I like that better..."
"It was hot as hell."
"Ngh, hah... your cock... is hot too..."
"How so?"
I slightly changed the angle of my thrusts. When I angled upward, scraping against the spot where her stomach would be, Yu-min’s body jolted, and her pussy clamped down.
"It's big... and it has a nice curve... it's thick... it fills me up so much, it feels amazing..."
She spoke in a sweet voice through ragged breaths. A sudden streak of playfulness hit me.
"Didn't you say it was small before?"
"Y-you weren't even getting hard for me back then, uuuugh...!"
When I thrust my hips playfully, a sweet moan escaped her. As I poked around inside her gasping pussy, her moans turned into full-blown cries of pleasure.
"Wait, let's rest for a bit... I'm tired..."
Ignoring her, I slightly increased the speed of my hips, and Yu-min’s legs wrapped around my waist. Then, she whispered sweetly into my ear.
"Don't be so mean... be a little more gentle..."
It was a temptation more than enough to snap a man's reason. When my body instinctively stiffened, Yu-min panted and cupped both of my cheeks.
She pushed my head back slightly, and our eyes finally met.
The face I saw then...
"...You look so fucking hot right now."
"...Huh?"
It was the face of a female in heat.
Two dark eyes, melting and dripping with honeyed lust.
Cheeks flushed crimson from the rough act.
Her skin was fine and unswollen despite the tears, and her expression was dissolved in pleasure.
I liked it immensely. I found myself staring, completely entranced.
Yu-min looked at me for a long time with that expression before squeezing her eyes shut.
She leaned her head forward slightly. What she wanted was obvious. Something we had intentionally avoided doing often. I knew I couldn't hold back.
She was so lovely that I couldn't suppress myself. As I lowered my head and pressed my lips against hers...
Beyond her parted lips, our tongues tangled together with a searing heat. It was a sticky kiss—one we had done occasionally before, but this felt entirely different.
It was a kiss thick with affection that left us both breathless. While our tongues were entwined, my cock hardened again inside her.
As I scraped against her vaginal walls, she let out nasal whimpers, her body shook, and the arms around my neck tightened.
But even that tension melted away as I kept twitching my hips to scrape her walls even more.
And that wasn't all.
"Don't... stop... Mmm, chu..."
The usual prickly attitude was nowhere to be found. Yu-min was acting cute, her voice full of charm, showing her affection without reservation as our tongues danced.
I felt the same. In this moment, I realized it was impossible to treat her roughly.
Though her uterus might have a different opinion.
We only pulled apart after I had squeezed out every last drop of semen left in my urethra.
Leaving Yu-min behind, who was watching me with eyes full of blatant longing, I looked at the condom I hadn't even removed yet.
Not much time had passed. It felt like we’d been at it for hours, but in reality, it hadn't been that long.
So, the semen inside the condom was still fresh. It felt like it could still be used.
Looking at it made the blood rush downstairs again. The suggestion Yu-min had made earlier came back to me.
"Kang Yu-min."
"Calling me by my name again... what?"
"Can I flip the condom and put it back in?"
Her body flinched. Even though she had just been creampied, the idea seemed to turn her on.
Did she like the idea of completely subverting the purpose of a contraceptive? After a moment's hesitation, Yu-min nodded and wiggled over to lie down next to me.
"Then let's just rest with it inside. I'm a little tired."
"That's because you don't exercise enough."
"Whatever, seriously..."
Despite her words, Yu-min lay on her side and quietly watched as I took the condom and flipped it inside out.
In that sense, flipping a condom wasn't easy. Even though I was quite good with my hands, it was a struggle.
Maybe they were just made that way. Putting it back on after flipping it was the easy part.
The sight clearly showed it was already used and never intended for reuse. Some semen even got on my hand.
"Give me your hand. You're so messy."
As if even a single drop of my semen was too precious to waste, Yu-min took my hand into her mouth and sucked it clean.
I wrapped my clean hand around Yu-min's waist, and she slightly parted her legs while still lying on her side.
"I can't kiss you since I just ate your cum."
"...Really? I, uh, no, it's fine. Whatever, it's just a kiss."
Looking at me with eyes full of clear disappointment, Yu-min used her hand to spread her pussy while keeping her legs parted.
Her pussy was already oozing with the semen that had filled it. When I pressed my throbbing cock against it, a sweet moan burst from her lips.
"I told you I wanted to rest..."
"I was going to, but your pussy feels too good."
"Calling your Noona 'you'... ngh, ah."
Yu-min’s shoulders flinched, clearly aroused. This woman, who was my older sister and had now become my fuckbuddy, let out a helpless, loose smile as she accepted my cock.
Accepting the condom-clad cock covered in semen, using her own vaginal walls to wash off the semen smeared on the outside...
Yu-min, still lying on her side, lifted her leg slightly and placed her thigh in my hand.
"I guess... I have no choice."
With a beaming, giddy face, Yu-min whispered with an expression of pure happiness.
"Go ahead and use your sister's pussy as much as you want."
As if she knew that would be even more arousing.
Knowing full well I would be exhausted the next day, I kept moving my hips.
Until the darkness faded and morning came.
However, when I stumbled out of bed that morning, the text message on my smartphone had enough power to wipe away all that happiness and fatigue in an instant.
[Eldest Noona]
[Jin-ah, have you seen Yu-min?]
[She didn't come to her room. If she's there, please tell me.]
[I'm worried.]
"...Fuck."
I hurriedly woke Kang Yu-min, who was sleeping beside me with a blissful face.
