Chapter 72: Night Walk (1)♥
Chapter 72: Night Walk (1)♥
We slipped out in secret. One might argue that since we were both adults, there shouldn't have been an issue even if we were caught leaving.
In reality, that wasn't the case—especially considering that Kang Yu-min knew about my relationship with Yu-ri, and Eldest Noona had her suspicions.
Just the way we were dressed and the fact that we were heading out alone at this hour provided more than enough circumstantial evidence. Even if it weren't for Noona or Kang Yu-min, anyone could have vaguely guessed what was going on.
"…Yu-ri, do we really have to do this…?"
I glanced anxiously at the smartphone in my hand. Yu-ri walked with the corners of her mouth curled into a smile, as if enjoying my unease.
Between her rhythmic, clicking steps, I could see she was wearing a long skirt.
As if showing off her bare legs earlier had been a calculated move to grab my attention and get me hard, Yu-ri had only put on that long skirt right before we stepped out.
There was nothing underneath it.
No underwear, no stockings.
Actually, saying there was nothing would be incorrect.
I thought about the object—something between a rotor and a dildo—that was the sole occupant of that space.
A vibrating sex toy designed to scatter pleasure.
Yu-ri had ordered it a while back, and though she’d expressed some disappointment, saying it wasn't quite as good as 'Oppa’s cock,' it was still quite the device.
And right now, it was tucked inside Yu-ri’s pussy. Since she wasn't wearing any underwear, it wouldn't have been strange for it to slip out at any moment, so her steps were naturally cautious.
Her stride was narrow, and because she was so focused on keeping it from falling out, her pussy juice was flowing out in a drenching mess.
I knew this. After all, walking behind her, there were sounds I couldn't help but hear even if I didn't want to.
If it were summer and she couldn't wear a coat, she would have been caught long ago. Even muffled by the coat, the sound was that distinct.
Squelch, squelch.
On one hand, the protective brother in me worried if it was okay for her to be dressed like that in this freezing weather. But then again, considering I’d already kissed Yu-ri like a lover and scattered my semen all over her uterus, those worries felt trivial.
Besides, my cock was giving me an enthusiastic thumbs-up. As proof, I had to wear a long coat myself to hide my crotch.
Both of us in long coats. Thinking about it now, we were a suspicious-looking duo.
But neither Yu-ri nor I had the luxury of worrying about that. We left the building and headed straight for the park near our house.
"It’s been a while since we came to the park, hasn't it?"
"I guess so," I replied, though I had other thoughts. "Then again, there’s rarely a reason to come to the park. Especially with the weather like this."
"That’s true. It’s been so cold lately."
Yu-ri shivered as she spoke, a gesture so potent it made me reflexively want to ask if she was okay.
"Are you alright, Yu-ri? With that... inside you..."
"Hmm? Oh..."
My sister played dumb with practiced ease. Without suppressing her wide grin, she turned a seductive gaze toward me.
"I’m fine. My body is running hot anyway. I’m already... incredibly wet."
And as if it were the most natural thing in the world, Yu-ri flashed a suspicious smile.
It was a reaction that suggested she had been waiting for this.
Even her soft chuckles were wicked. It felt like she had a scheme in mind, and it was obvious what that scheme was.
Perhaps it only seemed that way because I already knew the answer.
I swallowed hard and continued toward the park with Yu-ri.
I didn't even touch the switch on the way there. To be precise, I couldn't.
Regardless, our task was clear.
As we walked, the reality of it became even more vivid.
The sticky, squelching sound. The sound of something rubbing inside a pussy drenched in juices was incredibly lewd.
It wasn't even that late, and there were still a few people scattered about the park. The sudden thought that we shouldn't be doing this crossed my mind.
However, my arousal had completely hijacked my brain. I felt the cool, refreshing night breeze as we reached the park.
"It really has been a long time..."
"Has it been that long?"
"Yeah. You might not know, Oppa, but I never have a reason to come to the park."
I suppose the Gen Z crowd these days doesn't really hang out in parks.
Or do they? Maybe the delinquent kids still do.
I imagined them huddling in some sunless corner to smoke, but there was no point in dwelling on it. I doubted Yu-ri would know either.
"…Then, shall we start?"
I changed the subject to face the matter at hand.
Holding my smartphone in one hand, I stared at Yu-ri.
Clear text was displayed on the screen.
[!A Special Quest has appeared!]
[!A special effect will be applied during this quest!]
[Special Effect: The participant becomes immune to heat and cold for the duration of the quest!]
[The youngest, Kang Yu-ri, walks 200m or more while naked 0/200m]
[Reward: 1,000,000 Won Cash]
[The youngest, Kang Yu-ri, walks for 30 minutes or more while wearing an active sex toy 0/30]
[Reward: 1,000,000 Won Cash]
Quests that could be performed simultaneously. It even provided a generous effect, as if acknowledging that these weren't things one should be doing in the middle of winter.
I swallowed hard and looked at Yu-ri. She gave me a devious smile and spoke.
"Yeah, let’s start."
*
The quest had actually appeared right after Yu-ri suggested the night walk.
On one hand, I thought, 'Of course,' but on the other, I realized it had been a while since the game had given me a quest.
It almost felt like I was doing so well that there was nothing left to give me...
But seeing the quest now, it felt more like the game didn't think a quest was worth giving unless it was even more perverted and decadent.
Or maybe it was telling me to be more honest with my fetishes.
Wait, if that were the case, shouldn't there have been a quest related to Kang Yu-min? The fact that there wasn't made me wonder if that wasn't it after all.
Regardless, since it had been a while, the rewards were quite generous.
I’d received so much during major events that I might be biased, but compared to the usual, this was something to be grateful for.
At this point, I started to wonder what this "Family-Friendly Game" ultimately wanted...
"So... which one should we start with?"
But now wasn't the time for such thoughts. I nodded and looked at Yu-ri.
"I want to do both."
Yu-ri was bold. With a bright smile, she took off her coat as if she’d been waiting for the moment.
"I think I’ll get cold halfway through... so let’s finish quickly, okay?"
She said that, but we both knew that wasn't the real reason. I didn't stop her; I just nodded.
I was just as turned on as she was.
Seeing my nod, Yu-ri smiled brightly and pointedly removed her coat.
She wasn't wearing anything underneath, so her skin was fully exposed. She simply unbuttoned the side of her long skirt and lowered the zipper, letting it flutter down to the ground.
One by one, the layers of fabric settled on the floor. For a moment, I thought about them getting dirty.
But that was nothing compared to how Yu-ri’s body was about to be dirtied with semen.
"Ngh, ah."
Yu-ri stood there, proudly flaunting her beautiful naked body under the moonlight.
Large, full breasts, a slender waist, and a belly that was smooth, unlike Noona’s prominent Venusian mound.
And below that, her pussy was dripping with juices, her pussy hole pulsing as if searching for a cock.
Her wide pelvis and equally large buttocks were striking.
Like a perfect middle ground between Kang Yu-min and Eldest Noona, my younger sister stood under the moonlight with a lewdness that would make any man’s cock rock hard.
"Oppa, turn it on..."
My sister’s voice was thick with pleasure and desire. I swallowed hard and reached for my smartphone.
Modern rotors were convenient, supporting smartphone connectivity.
With just a press on the screen, it would activate, and I could choose the intensity and the specific areas of vibration at will.
I could choose whatever I wanted. I could have just picked at random, but I found myself swallowing hard as I carefully selected the vibration patterns.
The device was designed to send vibrations sequentially to the areas I tapped. I considered the spots my cock was familiar with, remembered which parts of her pussy my erect cock usually hit, and tapped the corresponding parts on the diagram of the sex toy to set the vibration.
"Ngh, ah, ahh... Ah, it feels like Oppa’s cock..."
The low, heavy hum of the vibration echoed. Yu-ri let out a sharp breath and twisted her waist, dripping sticky pussy juice onto the rubber-chip flooring of the playground.
This was a floor laid down for growing children, yet it was being dirtied by the juices flowing from a pussy ready to make a child.
That depraved sight captured my gaze. It made my own cock twitch inside my pants.
Yu-ri must have been thinking something similar; she stared at the ground with a blissful expression and let out a sweet moan.
Then, her body twitching, she waited for my command. Meeting those dark eyes fixed on me, I reflexively swallowed.
"Let’s go for a walk. You need to move."
"Ngh, yes..."
Yu-ri answered in a submissive voice and began to walk. Dripping sticky juices, she panted, resting a hand on her full breasts as if to steady her racing heart.
"Faster."
I slapped her ass to get her more excited, and Yu-ri’s body jolted at my touch as she continued to walk.
"Do you see your friends much lately?"
"Ngh, y-yeah, yeah, I see them..."
"Really? Any of them live in this neighborhood?"
I could clearly see her pussy clenching tight. Droplets of juice fell, staining the ground.
Some child would run over this spot later, only realizing much later in life what that strange smell was. That sudden insight sent a chilling thrill down my spine.
"Ngh, ah, I don't like this..."
"You have to answer me."
"There... are some..."
Yu-ri looked around, appearing both fearful and excited, her breath coming in ragged gasps. Sweat beaded along the curve of her back.
The immunity to heat and cold was clearly working; the only sweat on Yu-ri’s skin was from her sexual arousal.
"Have they ever met me?"
"Yes..."
"Then it would be really bad if you ran into them like this, wouldn't it?"
It really would be, but that didn't matter. What mattered was how incredibly hot those words were.
"Because it would be quite a problem if word got out that you’re a pervert who’s dying to have outdoor sex while exposed with her brother."
Yu-ri writhed, her breathing becoming even more labored. Her back arched and relaxed repeatedly as she hit a climax. Her abdomen trembled slightly, and her gasping breaths grew sharp before subsiding again and again.
"And it would be even worse if they found out you’re such a pervert that just imagining it makes you lose your mind and come."
A flood of pussy juice soaked the ground. Passersby could only be seen in the distance, where the lights were.
If we stepped into even a slightly brighter area, we would surely be caught, but the mere thought of it made my cock throb.
The inside of my underwear was sticky with pre-cum. I was suffering from a feverish urge to pull it out right this second.
It was a desire that was difficult to endure. If I had my way, I would have dropped my pants right here and fucked Yu-ri like a dog.
The line that had long since been broken by the game now only served to wave me through like swaying grass, and emboldened by that, I stepped closer to Yu-ri.
"Yu-ri."
Yu-ri, who had been moaning softly, turned her glazed eyes toward me. I swallowed hard and let my hand crawl along the contours of her face.
"Suck it."
Holding her chin with the hand that had traced her face, I gently guided her head down.
Before I knew it, I had unzipped my pants and pulled out my cock.
It was larger than usual, drenched and sticky.
An 'Oppa’s cock' so seasoned that one could smell the thick pre-cum and arousal even from a meter away.
It was an irresistible temptation for Yu-ri. Suppressing even the fear of being caught at any moment, she knelt.
"Yes..."
Her tongue flicked out like a greeting and wrapped around the head of my cock. I felt my brain white out at the sensation of this—an act of outdoor, exposed, incestuous fellatio I had never experienced before.
This is why you raise a younger sister.
