Chapter 153: Side Story - Bunker (11) ♥
"I... I seriously can't believe you."
"I said I was sorry."
"Is 'sorry' all you've got? Are you actually insane?"
"Come on, it's not like you didn't enjoy it."
"Who—who enjoyed it?!"
"I mean, for someone who didn't enjoy it, you sure were rubbing your pussy a lot. You were soaking wet..."
"Hey! Shut up!"
It was something I’d done purely on impulse, but I didn't exactly regret it or feel any self-loathing.
To be honest, it was the most satisfying ejaculation I’d had in a long time.
Man, maybe it’s because I’ve been living without any dopamine lately. I do feel a slight sense of defeat since I came all over Kang Yu-min, but...
She was flicking her bean while looking at my cock, so aren't we even?
At least, that was my logic, so I stood my ground.
"Seriously... this is insane. I mean, to your own family... to your Noona..."
"Why is it insane?"
Yu-min, who had been wiping her face under the cascading water, turned to look at me with a deeply grimacing expression, as if she couldn't believe my words.
"Then... would it be okay if I... you know, sprayed that... on your face?"
I figured she was trying to use a bit of 'put yourself in my shoes' logic to get me to admit I was wrong.
But I didn't give a damn.
"I'd be down."
"Wh-what?"
"Sounds great, actually."
"You... you perverted... crazy..."
Her mouth hung open as she tried to find the right insult, but she just ended up sputtering.
I chuckled at her reaction and stretched my body under the stream of the shower.
Of course, I wasn't being entirely serious.
I probably wouldn't actually feel that great about it; the unpleasantness would likely outweigh any arousal.
But that was beside the point. As long as I could tease Yu-min, I was willing to lie as much as I needed to.
Yu-min seemed to realize this, as her flushed face twisted into a grumble.
"You bastard."
"Hey, if I'm a bastard, then you're a bitch, since we're siblings."
"Pervert."
"I don't really want to hear that from the girl who was masturbating while her brother's cum was being sprayed on her face."
"...Do you... do you even realize what you're saying...?"
Thanks to my persistent efforts, Yu-min found the situation absurd, but she stopped taking it so seriously.
It wasn't a good thing for us to get all serious and awkward over this.
That would mean we were starting to see each other as members of the opposite sex, which meant there was no telling what might happen next.
I thought this dynamic was better.
Beyond just washing, eating, and sleeping together naked.
A relationship where we didn't think twice about masturbating while the other was right there.
Anyway, it wasn't like there was anyone left to judge us. With society completely trashed, I felt like it was a waste of energy to worry about every little thing.
Besides, having conversations and skinship like this actually made me feel more at ease.
I rubbed my hair dry and reached around for the soap-slash-shampoo-slash-body wash.
"...Is the soap over there?"
"Yeah."
"Ah, I was going to use that."
"Then use it."
"You could've passed it to me. Stingy bastard."
"Whatever."
Realizing there was no soap in my stall, I sighed and stepped into the stall right next to mine.
Looking at Yu-min's body, the cum I had sprayed over her cleavage, breasts, face, and lips was already gone, washed clean.
"...What are you looking at?"
Looking at her like that, strangely, I couldn't take my eyes off her for a moment. I didn't know why.
Something about it tugged at a memory.
I just kept thinking about when I sprayed her face earlier.
It was a strangely vivid image. That scrunched-up face. The twist of her mouth that seemed to show disgust.
And yet, those cheeks were flushed deep red, filled with a clear excitement that she couldn't hide from me.
Not to mention her fingers, which hadn't stopped digging into and rubbing her pussy.
All of it remained in my memory, and strangely, facing Yu-min now, it wouldn't leave my mind.
"What is it...? Why are you suddenly..."
Yu-min stopped mid-sentence and fell silent, looking at me intently with a strangely dissatisfied pout.
I saw her flushed cheeks, and her arm raised as she rubbed her body, revealing her armpit and her bare breasts.

"...You."
That was when I snapped out of it. Yu-min spoke up suddenly, her eyes darting around with a subtle expression.
"You're seriously a crazy bastard..."
What was it now? I followed her gaze, and only then did I realize why she was saying that.
My cock was standing tall, throbbing.
It hadn't been that long since I'd ejaculated, so it shouldn't have been able to get up again so soon.
Was it because I'd held back for a month?
Or... was it because the 'porn' I'd just witnessed was echoing in my brain, overriding my physical limits?
Or if not that...
I tried to ignore the ominous possibility that came to mind, blankly watching what Yu-min was doing.
Yu-min saw my gaze land on her breasts—specifically her nipples—but she didn't cover them.
Instead, she stood tall, flaunting her body. Her breasts were firm, the perfect size to fit in a hand.
Below them, her skin was smooth and wet, leading down to a crotch and pussy that were almost entirely hairless, save for a bit of fine fuzz.
A pussy that was clearly glistening, soaked with a fluid other than water.
There were plenty of things Yu-min could have said to me right then.
That I was a pervert, or a lowlife for getting hard looking at his sister.
That I was insane, or out of my mind. There were many things she could have said.
But instead of speaking, Yu-min slowly lowered her hands, bringing them together, and stood there silently, glaring at me.
In the inevitable silence that followed, we siblings stared at each other.
Yu-min was the one who broke the silence.
"What are you doing?"
"...Huh?"
"You said it wasn't a big deal. You said the one who cares is the weird one, right?"
The words I had said just a moment ago. Yu-min spat them out with a sharp edge to her voice and leaned back against the wall.
"Do what you're gonna do."
At her words, I looked down at my cock, which was standing tall and twitching.
Could I say it? No, was it too early?
And, was it even okay to do this?
Despite my various hesitations, I decided to focus on what I could do right now.
"You first."
"...Perverted bastard."
Yu-min spat the words out, but with her breath already turning ragged, she lowered her hand to her crotch.
Her other hand? It reached out and grabbed my forearm.
"Hold me."
"Why?"
"What if my legs give out and I fall?"
"Ah."
I understood and gripped Yu-min's forearm. She held onto mine, and while being held, she began to mess with her crotch.
"...Ngh."
Well, I was the only one who had reached a climax earlier.
Yu-min hadn't reached hers yet, and just as a man feels like he's going crazy if he stops before coming, it was the same for a woman.
At least, that was my understanding.
So, it wasn't strange for Yu-min to start masturbating.
"Just do it like you usually do."
"...This, ngh, is how I usually do it."
"How? You're just teasing it."
"Warming it up... like this."
Letting out a ragged breath, she spread her labia and traced her index finger over the exposed flesh.
As faint moans escaped between the wet, squelching sounds, Yu-min closed her eyes for a moment, trembling as she continued.
"Once it's warmed up enough, then I use my middle finger..."
Yu-min's middle finger moved. I couldn't see it clearly from my angle, but she was teasing her pussy hole, spreading her juices around.
Did she feel like she wasn't getting wet enough because of the pouring water? Yu-min tried to insert her middle finger into her hole but stopped with a frown.
Her eyes turned to me, hesitating. I knew exactly what she was thinking and let out a hollow laugh.
"Pervert."
"...Look who's talking."
"Instead of that, how about this?"
Impulse and courage mixed together and tumbled out of my mouth. Just as spoken words can't be taken back, I looked into Yu-min's questioning eyes and knew I couldn't stop now.
We were both far too aroused for that.
In reality, it had been a year and a half of abstinence. Because we were stuck in a bunker with nothing to even use as material for masturbation, we were hopelessly turned on by the sight of a real body of the opposite sex for the first time in forever.
Setting aside the fact that it was the body of a sibling, of family.
But I hesitated and dialed back what I had originally thought of.
"Wet it with my spit."
"You... crazy bastard."
"I mean, whatever. I already sprayed your face. I can at least do this much for you."
Yu-min's face twisted for a moment as if she were thinking, Is that so? But perhaps because she was so aroused that her honey-thick juices were dripping down, she couldn't hesitate any longer.
"Then..."
With a look that asked if this was really okay, Yu-min slowly raised her hand. Her finger approached my face.
I took that middle finger into my mouth.
"Ngh."
Following her soft moan, I sucked on her middle finger while stroking my cock rapidly.
I sucked it until it was wet enough so it wouldn't hurt when it went inside.
My cock throbbed even harder at the thought of my saliva entering her.
Soon, Yu-min's thoughts reached the same place.
"...Seriously, this is so... perverted."
"So what? Since when were we not?"
Unable to find a rebuttal, Yu-min mumbled something under her breath, then took the finger I had just released and brought it down to her lower body, panting.
Squish.
"Mmm..."
Her middle finger, soaked with my saliva, pushed inside with a wet sound.
It parted her pussy hole and rubbed against the vaginal walls as it dug deep. Yu-min gripped my forearm tightly as she moved her hand.
Schlick, squelch. The wet sounds echoed clearly even through the noise of the shower. My hand grew faster, and it was only natural that my flowing precum was being sprayed all over Yu-min's thighs and stomach.
We were inches apart, and we were too turned on to hold back.
Yu-min and I continued to move as if possessed, looking at each other's faces through the rising heat of our arousal.
Beyond the faces were our bodies. Yu-min used my cock, and I used her pussy and breasts as visual stimulation.
A sudden thought occurred to me.
The realization that after this, we would never be able to masturbate normally again.
But, who cared?
It wasn't like there was anything else to do for fun anyway. Is it really so bad to watch each other while we masturbate?
Right, it's not like we're specifically directing our lust at each other... we're just lending a hand as family, as siblings.
It's not like there's any other stimulation around, right?
After finishing my rationalization, I felt the urge to ejaculate surging up, and Yu-min was also panting, her legs trembling violently.
"Hey, I'm..."
"Me too, almost..."
"Together..."
Together?
Despite the questioning thought, I nodded, and Yu-min took a deep breath, her chest heaving as she scraped her vaginal walls with the finger digging inside her.
"Ngh, ah, ahhh...!"
She yanked her finger out all at once, her hips bucking.
With a splat sound, her juices sprayed out. I ejaculated almost at the exact same time, and I had the impression that our fluids were mingling in mid-air.
As my cum poured over Yu-min's lower belly and her juices soaked my thighs and calves...
I continued to stroke my still semi-erect cock, rubbing the remaining semen onto Yu-min's stomach to wipe it off.
And Yu-min didn't seem disgusted at all.
