[Archived Directive]

[Reward: Creation of a comfortable living room including a TV connected to OTT services, the latest gaming console, a PC, a library of curated books, a sofa, and a spa]
[Progress: 0/7]
When I first saw that directive, I thought there would be both easy and difficult aspects to it.
After all, it had only been about two days since we actually started having sex.
So, if we were told not to do it, we could just go back to living the way we did before.
But on the other hand, as I mentioned, there were difficulties.
There were no other stimuli or forms of entertainment, and we shared a bed.
Sleeping and waking up in the same bed, seeing each other in our most vulnerable states.
Moreover, the biggest problem was that we even bathed together.
Keeping that in mind, I looked at Kang Yu-min.
I wanted to discuss this matter so we could enjoy ourselves properly a week later.
Above all, with a reward like that, there was no reason to pass it up.
With that thought, I looked at Kang Yu-min’s face and was momentarily taken aback.
Her face was etched with clear bewilderment.
It was at a level where I couldn't intuitively understand why she was making such an expression.
Why on earth? Was it because she didn't expect the reward to be this massive?
Or was it because she realized the fact that we had been having sex?
Neither seemed particularly convincing. Since the bunker could suddenly produce uncontaminated cola, bedding, and condoms out of thin air, creating a new living room wouldn't be difficult.
I was about to ask her what was wrong, but Kang Yu-min spoke first.
"I... I don't understand!"
Her voice, forced into a bright shout, grated on my nerves. Did she mean it was too easy? After how much she'd enjoyed it?
As I frowned slightly, Kang Yu-min looked at me.
She looked so confused she couldn't even read my expression.
"I don't get why... why it's giving us this when we've never even had sex."
Only then did I remember the fact I had forgotten.
We had been engaging in incest while maintaining the perception that we weren't having sex, but merely masturbating.
"I mean, we're siblings, right? There's no way siblings would have sex. Right?"
The way she spoke while forcing a grin was pitiful. I didn't know if she was doing it because she was afraid her perception would crumble, or if she was just being stubborn.
I couldn't play along because I immediately realized what that directive was aiming for.
And looking at that goal, this directive was difficult.
The entity that issued this directive did not allow us to conveniently lie to ourselves, calling it masturbation while ignoring the fact that it was sex.
It wanted us to recognize that we were having sex, that we were committing incest—that a biological brother and sister were playing a dangerous game, relying on nothing but a single condom.
Perhaps even more than that, it wanted us to choose incest even after recognizing it for what it was.
I shivered for a moment at the chilling sensation.
"Right? Isn't that right?"
"...Kang Yu-min."
Looking into her pitiful eyes as she stared at me, I grabbed both of her shoulders.
"Get a grip. You know what this means too."
"Huh? What? I don't really..."
"I know exactly what you're thinking. You're thinking we just masturbated together, and that we just got a little help while doing it... or that we just used each other's bodies however we wanted to masturbate."
"That's... that's right, isn't it? You were also really..."
"But this directive isn't going to follow our personal perceptions."
Hearing my words, Kang Yu-min froze in place and stared at me blankly.
As if asking what I meant.
My biological sister stared at me with trembling pupils, forcing an expression that claimed she had no idea what was going on.
Looking at that expression, I felt something strangely heavy in my chest.
Something like pressure, a sense of depravity, and guilt.
Yet, a sensation that strangely seemed to crave liberation.
Nevertheless, I spoke as if I had no choice.
"What we did was sex. And incestuous sex at that."
There was no response, but I continued while keeping my hands on her shoulders.
"And for one week... we can't have sex."
Kang Yu-min didn't answer me. Not even when I took my hands off her shoulders.
*
Despite the sudden change in our routine, our time continued to flow.
The problem was that the dopamine had been drained.
Since losing something you already had is the worst feeling, I felt like time was moving incredibly slowly.
I've never dated, but I wondered if this is how it feels to be in a long-distance relationship right when things are heating up.
With no books to read, nothing to watch, and nothing to do.
Kang Yu-min and I spent our time as if we were back to how we were before this relationship started.
The only differences were that the bed was nice, and this relationship had been put on a temporary hold.
Even though Kang Yu-min seemed to be feeling a mix of complicated emotions, irritation, and even anger.
I guess we were still sleeping together, though.
Of course, it wasn't like we weren't doing anything at all.
"...Hey."
"...What?"
"Move your hand. It feels like we'll have to restart the week if you keep this up."
"No... wouldn't this much be okay? This... this isn't sex. This is..."
"It won't count if they include oral or manual stimulation in the calculation."
"Ugh..."
Even when we were just sleeping together, Kang Yu-min would pointedly touch my body.
As if she wanted more, or perhaps hoping I would be the one to cross the line first.
She would fiddle with my body, try to pull down my pants, or try to take my hand and use it as she pleased.
She did it so often that I felt guilty for sternly pushing her away.
And I could understand her. We had spent two whole days with our bodies constantly overlapping, kissing, and having sex until the condoms were full.
To suddenly be unable to do that? It was enough to drive anyone crazy.
It was the same for me.
However, the reward was so sweet it was practically electric—enough to make the endurance worth it.
It contained every stimulus we had been deprived of for a long time.
Things to watch, things to enjoy, and even a spa and sofa that could serve as perfect lubricants for our relationship.
Losing this, missing this opportunity, was something I couldn't even imagine.
So I had to be careful.
If manual stimulation counted as sex, we'd have to start the week all over again.
And even if "failure" didn't exist, if the timer reset every time we had sex, the goal would only get further and further away.
It was most rational to endure it now while I still could.
"...You're so mean."
It seemed Kang Yu-min didn't think so.
Well, what was she going to do?
I was the one with the cock.
What could a hole do besides being poked?
So I puffed out my chest confidently, and Kang Yu-min, seemingly finding me spiteful, slapped my chest with her open palms.
"Now, just go to sleep. We only have to hold out for a week anyway."
"What am I supposed to do until then?"
"Go exercise or something."
"You're really too much. How am I supposed to hold back?"
Kang Yu-min spoke to me in a sulky tone. When I shrugged, she glared at me with sharp eyes before suddenly muttering.
"Hey."
"What."
"Don't go back on your word."
"I won't. I'm not like you..."
I stopped mid-sentence. Kang Yu-min pointedly pulled down her shorts and placed her hand on her pussy, which was already slick with fluids.
Her pussy spread the sticky juices like drool as her thin fingers stroked over it.
The sight of it pulsing was incredibly seductive, and for a moment, I was lost for words.
It wasn't like resisting was easy for me either. Men just find it relatively easier to hold back, but it's only relative.
Was sleeping together from the start too much?
I let out a hollow laugh in disbelief, and Kang Yu-min, observing my expression, flashed a seductive smile.
"You pervert."
My crotch bulged. It grew and throbbed as if showing off. I could tell from the slight dampness in my underwear that pre-cum was leaking out.
My body was preparing for sex, producing plenty of lubricant as if telling me to shove it into that hole right this instant.
Even though I knew the woman in front of me was my biological sister, my family, my own blood, and a close friend—almost a bitter rival—whom I'd spent a long time with.
My brain, my body, and my balls didn't seem to care, producing the fluids necessary to impregnate the woman before me.
It felt as if my testicles were boiling. As I swallowed hard, Kang Yu-min reached out and slowly pulled down my pants.
"Hey, hey!"
"I won't touch it. I'm just... using it as material to masturbate... It's such a lewd-looking dick that just looking at it..."
"You..."
"You should call me Noona, shouldn't you?"
Before I knew it, Kang Yu-min had pulled her shorts all the way down to her thighs and was fiddling with her pussy. Listening to the squelching sounds and seeing that tempting color, I looked down at my own exposed member.
"This is really just masturbation. Right?"
Yeah, it was masturbation. Even if it was masturbation using each other as material.
"So, you should rub yours too. Just don't cum on me. Clean it up yourself."
Kang Yu-min smirked. I felt the blood rush to my head at her irritating expression and attitude.
Right, exactly. If I came on her, it might count as sex.
I went as far as taking out a condom and putting it on my dick before I started masturbating.
"Pussy."
"Slut."
"Degenerate, getting hard over your own sister's pussy."
"What about you, poking your pussy while looking at your brother's dick?"
We locked eyes and masturbated while looking at each other's bodies, at a distance where we would touch if we even shifted our weight.
I worried if this was really okay, masturbating while watching each other's bodies, but my hand wouldn't stop.
"Show me your breasts."
"...Haa, pervert."
Kang Yu-min barely managed to spit out the words with a melting tongue, yet she obediently lifted her top to show me her breasts.
And then.
"Your hand is getting faster. Do you like your sister's breasts that much? Want to see something better?"
Kang Yu-min took her shorts off completely, flexibly lifting her legs to spread her pussy and poke at it.
My dick throbbed instinctively, and the urge to ejaculate surged.
Feeling the urge to push her down and ram into her right then and there, I panted through gritted teeth.
"Come on, look at your sister's pussy... and cum a lot, imagining you're cumming inside me."
Kang Yu-min continued to masturbate, using the sight of me losing to pleasure as her material while she smirked.
Looking at each other's bodies, we siblings gradually realized.
That there was no longer a path to go back.
Even I was imagining pouring my semen into the deepest part of her uterus while looking at that pussy.
Before I knew it, my hand reached the base and moved rapidly, and Kang Yu-min also poked her pussy fiercely while drooling.
Just as the speed of my hand and the speed of her thrusting felt perfectly synchronized.
"Cum for me, inside...!"
"I'm cumming...!"
As if we had rehearsed it, we spoke at the same time and reached our climax.
The tip of the condom on my dick bulged and pulsed, while Kang Yu-min arched her back and gasped.
And I thought to myself that this might be the most difficult week since coming to this bunker.
