Chapter 155: Side Story - Bunker (13) ♥
"Why does it taste good?"
Kang Yu-min spoke with a look of bewilderment. I was just as puzzled, and there wasn't much we could use to form a solid theory.
So, lying side by side in the nude, I took a stab at an answer to her question.
"Because you're a total pervert?"
"Cut the bullshit. Seriously."
"What? Isn't it plausible?"
"Plausible my ass..."
"Then what is it?"
"Well... Oh!"
I thought my guess was pretty solid, but Yu-min clearly didn't agree. Surprisingly, she came up with a theory of her own—one that actually sounded quite convincing.
"Isn't it because of the diet?"
"The diet?"
"Yeah, the diet."
"Even if you call it a diet... Ah."
I thought back to the nutritional porridge I’d been forced to eat for the past year and a half.
It was eco-friendly, made only with healthy ingredients, and tasted like absolute shit.
It was food you ate only to stay alive.
I had a vague idea of what Yu-min was trying to say.
"So, you're saying because my diet consisted of that nutritional porridge, my cum ended up tasting good?"
"Doesn't that sound plausible?"
I felt like I’d heard something like that before. That the taste of a person's semen changes depending on what they eat.
I wasn't smart or knowledgeable enough to know if it was scientifically true, but...
"It makes sense."
The person who actually ate my cum said it was delicious, and there was only one factor that could have influenced it.
It was probably safe to assume she was right. I nodded, accepting Yu-min's theory.
"Right? Wow, I never thought that tasteless nutritional porridge would have a benefit like this..."
Yu-min marveled as she glanced down at my cock. I caught a glimpse of something like longing in her eyes and instinctively flinched.
"If I’d known, I would’ve tried it sooner."
"Would you have, though?"
"Why not? I just did it now."
"I guess so."
Everything felt a bit surreal, and I wasn't even sure how we’d ended up like this. I found myself wondering what on earth we were doing.
Still, the sense of self-loathing wasn't that strong. It wasn't just because I’d fully accepted this relationship as nothing special—simply two people using each other's bodies to satisfy their urges.
It was also because we’d decided not to harbor doubts or overthink things.
We wouldn't go out of our way to say this was weird or acknowledge the awkwardness.
Even if we were conscious of it, we’d agreed not to show it.
That was why I could look openly at Yu-min's breasts and thighs.
"No, seriously. Think about it."
"Think about what?"
"The nutritional porridge. It tastes like shit, right?"
"Yeah."
"But your cum is delicious."
"Right...?"
"Then even if the porridge is gross, can't I just use your cum as a palate cleanser afterward?"
The phrasing felt a bit off, but strictly speaking, she wasn't wrong.
"You want me to blow a load three times a day?"
"Why? Can't you?"
"It's a bit tough for a guy to pump out three rounds every single day."
"Oh, really?"
Yu-min's shoulders slumped in visible disappointment. Her hand, which had been creeping closer, was now touching my cock.
Whether I flinched or not, Yu-min began to fiddle with it as if it were the most natural thing in the world.
"But today... how many times did you cum? Three?"
"Yeah, I think so."
"But it's still hard?"
"...Maybe because I held it in for so long?"
A year and a half of abstinence was quite a long time. I’d only stayed celibate because there was no way to relieve the tension, but as soon as an outlet appeared, it was like the reins had been cut. I was getting erections like crazy...
Still, there was no guarantee I could keep this up every day. Honestly, I didn't think it was even possible.
"Anyway, that's it for the cum today. If you want more, try again tomorrow."
"Aw, come on. Just one more bite."
"What do you mean, 'one more bite'? Am I food?"
"Then, can I just lick it a little?"
Why was this girl so obsessed? As I stared at her with a look of disbelief and skepticism, Yu-min started acting cute, rubbing up against me.
"Hey, stop it."
"Please? I'll just lick it a little. Hmm? Just a bit."
"Seriously..."
I complained, but it was a pretty tempting offer.
I figured Yu-min wouldn't be very good at it since she lacked experience... but being sucked on felt pretty damn good regardless.
I pretended to hesitate for a moment before finally letting out a sigh.
"I might do it if there's some kind of return."
"A return... okay, I'll think about it. So I can lick it, right?"
"Go ahead. You pervert."
"Fine, I'm a pervert. Happy? I'm licking now."
I could understand why she was being so reckless. If the pussy juice coming out of Yu-min had been sweet and delicious, I would have been just as obsessed.
Even though it was Yu-min's pussy, it was still quite a turn-on. Licking and sucking it would be incredibly hot.
Since it tasted good, I would have sucked on it with everything I had, so I figured Yu-min felt the same way.
Above all, Yu-min was still a woman.
I didn't know much about the female psyche, but I assumed a cock was just as erotic to a woman as a pussy was to a man.
With that thought, I looked down and watched Yu-min crawl over to lie between my legs.
Humming a tune, she gently gripped my cock and looked up at me.
When our eyes met, she watched my expression while slowly moving her hand to massage it.
"...Tell me if it hurts."
"I don't think it'll hurt if you're gentle."
"I'm saying, tell me if it does."
"Got it."
As I gave my casual consent, Yu-min slowly lowered her head and stuck out her tongue.
Her reddened tongue, wet with saliva, dripped onto my cock. It was so hot it made my body twitch. Her tongue, heated by her high body temperature, traced along my foreskin.
However, the licking itself wasn't so pleasurable that it made me want to moan. Her tongue movements weren't enough to make my hips tremble or make me feel like I was going to ejaculate.
Part of it was her lack of skill, but I suddenly realized that it might be impossible to reach climax just from licking.
Perhaps that was why a certain desire suddenly surged within me.
Before I knew it, I spoke.
"If you want to eat cum, I think there's still some left in the urethra."
"Ure-wha?"
"Yeah, the urethra. The hole at the tip."
She started moving her tongue toward it. Fearing the worst, I quickly added:
"Don't put your tongue inside. It's not a hole meant for that, unlike a woman's urethra."
"Otay."
"Tits?"
"O. Kay."
"Ah, okay. Anyway, if you wait, more will come out of there. That's why even after jerking off, if you're not careful, you get cum on your underwear..."
Yu-min listened intently and nodded. Looking into her eyes, I suggested a method that had just come to mind.
"Take the tip of the glans into your mouth, don't use your teeth... and if you suck on it like you're using a straw, it'll feel good for me, and the leftover cum in the urethra might come out."
Yu-min's eyes instantly sparkled. I wondered if it really tasted that good, but on the other hand, it made sense.
The nutritional porridge was nutritionally perfect, but the taste was truly awful.
The problem was that "tasting bad" didn't mean it had a foul flavor.
It was literally tasteless.
It had no flavor at all. So, it was only natural to crave even the slightest bit of stimulation. I found it hard to understand why she was craving my cum when we even had Cola, but I let out a relaxed breath as I watched Yu-min purse her lips and suck on my glans.
"Mmm... that feels pretty good."
"Reawy?"
"Yeah, really good. I might not mind having this done every day."
Yu-min smiled with her eyes, seemingly pleased by the praise. Her face was pretty, just like mine or Mom's, so she was a sight to behold.
The fact that she was sucking my cock with such a pretty face was quite stimulating. And the sense of depravity from having my own sister suck me off was also quite intense.
I thought it wouldn't be so bad if this became a habit.
"...Keep doing it like that."
I felt at ease. Being sucked off without any intense technique had a subtle comfort to it.
It felt like soaking my body in warm water. Drowsiness began to wash over me.
With the background noise of Yu-min's enthusiastic sucking sounds, I slowly let my heavy eyelids close.
And just like that, I fell asleep.
It was a pleasant slumber.
*
When I suddenly snapped my eyes open, I was enveloped in a soft, cozy sensation.
What was this?
It was too light to be Yu-min's arm or body, yet it wrapped around my entire frame. Looking down to check my surroundings, I saw that my body, along with Yu-min's arm, was covered by something pure white.
"...This is."
Only then did the memories return. Taking a bath together, changing the instructions, and the series of events that followed when we went to bed.
Something that had permanently altered our relationship while providing a new form of stimulation for our life in the bunker.
Using each other's bodies to masturbate and having her suck my cock. Just thinking about it made my cock swell with an erection. I slowly lifted the thing that was tenting over me.
"The bedding..."
So this was the promised duck down couple's bedding. Even as I thought this, I worried that the pre-cum from my cock might soil the blanket, so I carefully tossed it aside and climbed out of bed.
The timing was vague. I didn't know what time it was, but at least seven hours had passed.
Since the condition for the bedding was seven hours of co-sleeping, there was no doubt about that.
As soon as I stood up, I walked over to the terminal.
After properly tucking the sleeping Yu-min back in, I began typing on the terminal, and something immediately popped up.
It wasn't the familiar directive to sleep together.
It was a directive that had already been moved to storage, as if Yu-min had already checked it.
My eyes widened as I glanced at Yu-min.
