Chapter 23: Reward (3) ♥
Chapter 23: Reward (3) ♥
“Do you really think this is okay?”
I had to ask, even as I felt the pull of a powerful temptation.
“Oh, come on! Why not? It’s not like I haven't seen it before. I’ve seen it plenty of times!”
This was the final line of defense.
Beyond this point lay a path that siblings were never meant to tread. It was obvious that if we crossed it, we could no longer call ourselves siblings, nor would we be able to think of ourselves that way ever again.
So I tried to hesitate, tried to stop, but I knew better than anyone that I wasn't capable of it.
We were already standing at the edge of the cliff. All that was left was to tumble down.
I reached out, trying to stop the fall, trying to resist the pouring deluge, but…
“Please? Just once? Hmm?”
I realized too late that I had no way to resist. Well, it wasn't exactly news that it was futile for a human to fight against a natural disaster.
Kang Yu-min was acting cute and wheedling—a rare sight—and I was playing along, pretending to give in to her whims.
In the midst of that, before I knew it, I was sitting on the bed.
How did things end up like this? I wondered, even as I fiddled with my smartphone.
[Automatic Contraception]
[OFF]
I repeatedly toggled the function on and off. I didn't feel any physical change. Did it not work directly on the body?
Was it even working? I was too afraid to test it. If I trusted this blindly and made an irreversible mistake…
Then what should I do? I was only indulging in this relationship because I thought I could handle the consequences.
If it turned into a mistake I couldn't take back, what then?
I was deep in thought.
“Hey, hey! Look at this!”
A burst of laughter rang out, making my worries feel misplaced. I turned my head to see Kang Yu-min cackling in the bathroom.
“Look how much this stretches! This is insane!”
I had no choice but to get up and head to the bathroom. A sight that truly made my eyes widen greeted me.
“…Wow, damn. What is that?”
A condom was sitting right there in the bathtub we had been in just moments ago.
It was filled to the brim with water, wobbling like a giant water balloon, stretched to a size unimaginable compared to its original form.
Could it really hold that much? Was the 100% contraception rate actually for real?
The thought crossed my mind. Come to think of it, there hadn't been separate sizes for large, medium, or small.
“Look at this, look. Isn't it hilarious?”
Kang Yu-min was incredibly excited over something so trivial.
Then again, it was a sight to see.
She stretched out her long, bare legs and kicked the condom balloon, making it wriggle and slosh inside the tub.
It was kind of funny. It made me feel like an idiot for worrying so seriously.
I laughed in spite of myself, and Kang Yu-min laughed along beside me. Right, what kind of ulterior motive could she possibly have? She probably just wanted to try putting it on.
I knew the word 'trust' didn't exactly suit the girl who was my second noona, but for once, I trusted her.
“It really holds a lot.”
“I heard survivalists use these as water canteens sometimes.”
“Really?”
“Yeah, some guy who was hitting on me at the gym told me.”
“‘Hitting on you’? Who would be crazy enough to try and pick you up?”
“Uh, excuse me? Are you looking down on your noona? Do you have any idea how many confessions I’ve received?”
“Don't people just give those out? I’ve gotten a few too.”
Kang Yu-min laughed as if she couldn't believe my words, but I figured that was just how things were.
Isn't it common for people to send confessions with the lightheartedness typical of adolescence?
Even if it wasn't that, sometimes people did it as a penalty for a game. I just assumed Yu-min’s narcissism was acting up again.
“Besides, I’m the one with the cock. Not you.”
“Whatever, seriously.”
Thump. The hand hitting my shoulder was weak. Was she worried about hurting me?
Given the physical difference between a man and a woman, there was no reason to worry about pain unless she was hitting me for real. But ever since I told her it hurt whenever she gripped my cock, she had been acting like this.
It wasn't strange for her to be mistaken, though.
“Hey.”
“Yeah?”
“Can we try using it?”
My shoulders flinched, but I played it cool.
“We are using it.”
“No, I mean…”
Kang Yu-min’s eyes darted around. When she realized I was staring at her bright red ears, she quickly covered them with her hands.
In the hand covering her ear, she was already clutching the condom she’d taken out.
“I just… I was curious what it would feel like to put it on… Can’t we try?”
“…Put what on what?”
“Ugh, you pervert…”
She spat out an unreasonable insult with a flushed face and let out a long sigh.
Yu-min took her hand away from her ear and held the condom out to me.
“Let’s put it on your cock. You pervert.”
She said it, braving the embarrassment.
In that situation, there was no way I could say no.
Even though it didn't quite sit right with me that she was calling me a pervert when she was the one making the perverted suggestion.
That was why I was currently lying naked on the bed.
“…First of all.”
“Don’t take your clothes off.”
“Wait, what?”
“Just don’t. Keep them on.”
“Ugh, this feels gross.”
Kang Yu-min rubbed her legs together. The sound of her pussy, soaking wet with pussy juice, squelching against itself echoed in my ears, but I tried not to pay it any mind.
Even though I was already erect to the point of pain.
“Got it? We’re just putting the condom on, okay? If you want, you can just watch me cum like that.”
“I get it, I get it. Honestly.”
Yu-min grumbled as she tore open the condom wrapper.
And then, I smelled the scent of the condom properly for the first time.
It was very strange.
The faint, characteristic scent of rubber remained, but it was mixed with a sweet fragrance and a lubricant that gave off a strong, artificial vibe.
It wasn't a scent I wanted to smell for long. But Yu-min didn't seem to mind. She held the condom in her hand, hesitated for a moment, and then…
“…I’ll suck it just a little to make it easier to put on.”
“What? Wait—”
Before I could stop her, she took my cock into her mouth.
It was a movement she was already used to. I flinched as a wave of pleasure hit me instantly. Yu-min’s eyes trembled slightly at my reaction, but she tucked her hair behind her ear and lowered her head further.
“…Ngh, hah… right there…”
At my involuntary moan, Yu-min tilted her head and swirled her tongue.
The pleasure itself was considerable. The fact that I was the only one naked while being sucked provided a different kind of stimulation.
Usually, when we did this, we were either both partially clothed or both naked.
Since it mostly happened in the bathroom, the latter was more common, but regardless.
The fact that only I was exposed felt different from usual. I let out a faint groan, feeling her tongue and lips envelop my cock.
In that sense, Yu-min’s technique wasn't bad.
In fact, it was quite excellent. Maybe it was because we’d been doing this for a whole month.
Yu-min sucked with just the right amount of pressure, repeatedly lowering and raising her head, taking my cock all the way to the back of her throat.
The tightening of her throat, her tongue constantly moving and scraping against the frenulum, the intense pleasure from the suction.
The abundance of saliva mixed in felt incredible. As the pleasure built up, I squeezed my eyes shut and savored the sensation against my cock.
It felt so good. Part of me wanted her to keep sucking like this forever, even if I didn't ejaculate.
The act of her servicing me with her mouth was an amazing feeling. If it were a stranger, I’d be worried about getting bitten, but…
I could trust Yu-min. Because we were family.
Setting aside the fact that having your sister suck your cock was a bit… off.
“I’m… almost…”
A tingling sensation shot through my urethra. The pain that spread faintly from the slurping suction. As she drank my pre-cum and licked it away with her tongue, I felt the urge to ejaculate surging from my testicles.
If I just came in her mouth like this…
“…Phew.”
“…Huh?”
A sudden coldness hit my cock. It was a relative coldness—the warmth that had been so vivid just a moment ago had vanished, leaving only a chill.
I shivered slightly as if catching a cold and looked down at Yu-min.
“…Did you like your noona sucking you that much? You pervert.”
Her smirking face was obnoxious. But she was armed with an undeniable truth. However, there was a fact even more terrifying than that.
“…When did you strip?”
“I did it while I was sucking you. When you had your eyes closed. You always close your eyes and enjoy it when I suck you. You were practically savoring it.”
She smirked. But I didn't even have time to feel annoyed by that face. My cock twitched.
Seeing Yu-min’s naked body again, it possessed a devastating power.
The smooth line of her abs, the lean, tight curves.
Her breasts weren't small, her buttocks were firm, and her body was both voluptuous and athletic, matching her short hair perfectly.
My eyes involuntarily followed the strands of hair falling over her collarbone, and then I saw her holding the condom in front of my cock.
No, wait. I have to stop this.
Before I could even open my mouth, Yu-min spoke.
“Hey.”
“Yeah?”
“You want to cum, don't you?”
As if she even had to ask. I was on edge because she’d stopped right before the climax. My hips trembled slightly from the lingering pleasure coursing down my spine, and Yu-min was gripping my cock, moving her hand gently up and down.
My cock was soaking wet with saliva and pre-cum. The squelching sound heightened the lewdness of the moment, but Yu-min moved very slowly, as if she had no intention of letting me finish.
The pleasure was too weak to make me cum, but it was more than enough to keep me erect and desperate. Feeling my cock throb, I anticipated what she was going to say next.
“We have the contraception anyway. And the condom. So…”
She trailed off. Did she realize something was wrong? There was a faint sense of anxiety in the way she glanced toward the door.
But that anxiety soon turned into the thrill of potentially getting caught. I knew because Yu-min let out a faint moan.
“Can’t I just… put it in once?”
Usually, this was something a man would say and a woman would refuse. In the midst of that irony, I wanted to say no, but…
Because she had stopped right before ejaculation, my arousal was at its peak. I felt like I would do anything just to be able to cum right now.
In the meantime, my reason was rapidly clouding over. When I didn't answer, Yu-min slowly rolled the condom over my glans, which was glistening and sticky with saliva.
“…Hngh.”
She let out an involuntary moan, her legs shifting and making a wet sound. The sound of her pussy, drenched in pussy juice, rubbing together.
As she did that, Yu-min struggled to roll the condom on, as if putting it on display for me.
It was incredibly arousing. The fact that she was putting something on me that existed for the sole purpose of affectionate sex, even though we were siblings.
It was beyond exciting. Heat rushed to my head, and the urge to ejaculate, which had been slowly subsiding since the act was interrupted, filled my testicles and raced up my urethra.
“Is it… on?”
Finally, the condom completely encased my cock. The faintly colored, glistening condom gave off a distinct rubbery smell. Yu-min stared at my cock as if possessed, then instinctively leaned down and kissed it.
It was just rubber, but she did it carefully, with love. When my cock twitched in response, she seemed unable to hold back any longer.
Yu-min climbed on top of me.
She pinned me down, straddling me.
I could see her glistening pussy. The wet heat, soaked with pussy juice, finally touched my glans.
I thought I wouldn't be able to feel it well because of the condom, but the heat was vivid. I felt the desire boiling inside me.
The impulse to thrust my hips up or grab her waist and pull her down spurred me on. But common sense, telling me I shouldn't, barely managed to hold me back.
Our eyes met. Her dark pupils were glazed with desire.
I was reflected in them. Panting, my own expression sticky and drenched in arousal.
Is this… me?
Am I this desperate to put it inside Kang Yu-min?
Her vaginal opening touched my glans. It flickered, licking and sucking at the tip of my cock. That alone made my body tremble. I wanted to go in.
This wasn't like our usual secret encounters in the bathroom. This wasn't about relieving each other's desires in the desolate environment of a game.
This was a secluded room where no one would come. A soundproof space where we didn't have to worry about being caught.
Even if we did it now, and kept going until morning, no one would find out.
That fact fanned the flames. Seeing my expression, Yu-min seemed to grow even more heated, and she bit her lip hard.
“Never mind… just don’t answer.”
With a dazed look in her eyes, Yu-min wrapped her arms around my neck and hugged me.
Our bodies pressed together. I felt her sticky pussy against my cock.
It was going in. Wait, really…?
Before I could even question it, her hips slowly lowered. With a heavy breath and a heated moan, Yu-min’s body trembled.
I felt a sensation that was both familiar and different. A different sensation from the eldest noona’s pussy I had tasted in the game.
Not raw skin, but a condom. A clear reality. Sibling incest. An act that would be indefensible if anyone saw. I panted, and Yu-min whispered right into my ear.
“If you don’t want to, push me away. Okay?”
Her voice was thick with moisture, sticky with sexual desire. I felt my cock slowly filling her internal walls, which were even stickier.
My head snapped back involuntarily. Yu-min kissed my neck. She held back a cry with the sound of her sucking.
“If you don’t push me away… I’ll take it as you wanting to do it…!”
She barely squeezed out the words as she lowered her hips. Squelch, squelch. My cock advanced, parting the closed vaginal walls, and finally…
Thump. With the illusion of Yu-min’s body surging upward, she jolted. Everything stopped as she gasped for air.
In the complete silence, Yu-min unwrapped her arms from my neck and leaned back.
“…Can you see?”
Smirking, with tears in her eyes, Yu-min laughed mischievously as if to tease me.
She spread her pussy with her fingers, revealing the junction where a hint of blood was visible.
My cock was completely inside Yu-min’s pussy.
The line had crumbled. It had already been crossed. The moment I realized that…
“Now, cum.”
I flinched at Yu-min’s words.
“Cum all of it inside your real sister’s pussy.”
Before I could even feel the sense of depravity from her following words, my head snapped back, and I ejaculated with a sense of release I had never experienced before.
It was an incredibly pleasurable ejaculation, unlike anything I had ever felt.
