Chapter Title: Seeing My Younger Sister Made My Mouth Water

-----------------------------------------------------------------

Time was running short.

There was more than enough time to just jerk off and get it over with, but it was woefully insufficient to complete this bullshit mission.

"J-Just keep doing this at home... haaah..."

I sighed, hand clamped over my mouth.

She clearly disapproved of me, but her trembling eyes were filled with curiosity too.

Thwap! Thwap! Thwap!

"Hngh... hnn..."

My dick felt a bit numb from the sex with Mom that had gone on from dawn until just a bit ago.

I'd been stroking it for a while now, but no matter how hard I gripped and pumped, there was barely any reaction.

And of course, the psychological pressure from that damn mission wasn't helping.

I ignored the system spouting whatever nonsense it wanted on its own.

Right now, I had to focus solely on Older Sister.

"Sis... you see this? I'm doing this all because of you."

"...W-What did I do! What the hell did I even..."

Muffled sounds came from beneath my palm.

"You walk around the house every day dressed so slutty like this... hnn... What am I supposed to do? I don't want to be doing this... ngh!"

It was the honest truth, based on facts.

Her fat pussy lips were squished by the leggings, poking out lewdly.

How could I not fuck a "big sis" with such a slender figure hugged tight by clothes that showed every curve?

"I-It's not slutty... I just... I just work out, that's all..."

She was trying to pass that off as an excuse to me, but it didn't land at all.

"Ngh... hnnngh... Yeah, you just work out, but seeing you like that drives me insane."

Older Sister's flustered face and quickening breaths made my hand move faster too.

"...H-Hansol. Really... I-I said no..."

"Why? What's so wrong about it?"

"...We're siblings. F-Family... That's why we can't...?"

She trotted out the same old principled argument.

I'd heard it so many times my ears were calloused.

"Who said? Who told you that?"

"I-It... It's just common sense..."

"You know why incest is taboo, then?"

"...B-Because kids from incest... are prone to g-genetic diseases... stuff like that..."

She was right.

It's to prevent genetic diseases or biological vulnerabilities in children born from incest.

Also to maintain order within the community.

"Do you want to have my baby, Sis?"

"W-Wha-What! S-Suddenly?!"

"That's exactly my point. Touching your tits isn't gonna get you pregnant, right? Seeing my dick won't knock you up either. And we're not gonna tell anyone about this. So what's the problem?"

"...Th-That's sophistry."

"How is it sophistry? You said we're siblings, family, so we can't. You said it's because of potential kids. But none of that applies to us."

This was crazy talk.

Something only an incest fetishist who'd devoured incest erotica would say.

Unfortunately, I was that incest freak.

"...S-So what do you want me to do...? D-Do you wanna... date or something... right now...?"

"I'd never pressure you like that. I just mean we should get to know each other slowly."

I shook my dick right in front of Older Sister's eyes.

"Th-This is how you 'get to know each other'!?"

"Nngh, you're curious about a guy's body too, aren't you? Last time, and even now, ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠your eyes keep flicking to it. I know."

Pok pok.

"Kyaa! Eek!"

She freaked out just because my cock lightly brushed the hand over her mouth.

"Not curious? About how big it normally gets? How it changes when it sees you? What comes out of it?"

Older Sister had already gotten a faceful of cum from me before and even licked it off her lips.

She wouldn't fall for my bullshit so easily, but even planting a seed of curiosity was progress enough.

"Better than meeting some weird guys outside, right?"

She'd bragged about having tons of guy experience before, but now she looked seriously conflicted.

"You won't get pregnant."

Older Sister blinked at me.

"Just slowly exploring each other's bodies."

"Ngh!"

I fondled her earlobe, and she squinted her eyes.

"...Aren't you curious what it tastes like, Sis?"

I smeared some precum oozing from my tip onto my finger.

Then brought it to her lips.

"Mmph... mph!"

She clamped her mouth shut and resisted, but the precum had already smeared across her lips.

"How's the smell?"

"Mmph!"

"The taste?"

"Mmmph!"

Her lips finally parted a sliver.

It was too narrow for my finger, but I wedged it in.

"Mmmngh!"

"Say ahh."

Good Older Sister relaxed her jaw so she wouldn't bite my finger.

That let my fingertip touch her soft tongue.

I tickled and teased it.

"Hee, mph! Mph! Lick, ngh!"

She probably wasn't licking on purpose.

She was just wriggling her tongue to dodge my finger, but ended up licking it anyway.

And the saliva pooling in her mouth went gulp gulp down her throat.

"Gulp... gulp..."

"Ngh... good girl."

Time was ticking down to seconds.

But I'd managed to feed her every last drop of precum.

The system was being unreasonable.

There was no set amount like last time with the facial, so I'd fed her whatever came out. This had to count as clear.

I was starting to lose affection for this system demanding the physically impossible.

This might've been a do-or-die crisis.

I couldn't choose destruction myself, so I'd have ended up doing the handjob anyway...

"Mmph... smooch, c-can't... breathe..."

My body went limp, crushing her under my weight.

I startled and quickly lifted my hips, rolling to the side.

I tried to pull my finger from her mouth, but Older Sister was sucking on it like a pacifier.

"Puhah..."

She exhaled the breath she'd held, and my finger slipped out.

"Sluurp... hnn..."

I don't know if she realized what she was doing, but she licked her lips like savoring the taste and gulped repeatedly.

"Gulp... haa..."

Her face flushed redder by the second. She covered it with her hand, then rolled onto her stomach on the mat and kicked her legs like splashing in water.

"Sis?"

"D-Don't talk to me. J-Just go to your room like that. Don't say anything."

This time, it wasn't just shame.

Before, it had been 8 parts shame and 2 embarrassment, but now it felt 50/50—or even more embarrassment.

"But Sis."

"Agh! I said don't talk and just go!!"

"No, it's not that—"

"Stop it!!"

It wasn't anything else... I was just worried about the wet stain on her leggings—right over her pussy.

Anyone who saw would think she'd pissed herself.

"Y-You're soaked, you know? If you stay here, it'll be awkward."

"W-What's soaked?!"

Actions spoke louder than words.

I raised my index finger high and jabbed it between her ass cheeks.

"Heeek!"

"You've been soaked since earlier. Go to your room quick, Sis."

Older Sister flopped around like a fish out of water.

She wrapped the yoga mat around herself and toddled off.

I watched her back contentedly, then picked up my panties and pants from the floor and put them on.

Now peace had finally returned.

I'd cleared that awful facefuck quest, and all the even worse ones that followed.

"Haaaah..."

I let out a deep sigh of relief.

All I wanted was to catch up on lost sleep.

"No."

Come to think of it, all those rape and facefuck missions were this damn system's idea.

"That is called rape?"

"Hoo... please go easy, go easy."

The system tsked its tongue, but I headed straight to my room and flopped onto the bed.

Sinking into the soft mattress made me feel like I owned the world.

...And I finally asked the thing I'd been wondering about—the biggest mystery.

"You... who the hell are you, anyway?"

"Cut the crap."

"You expect me to believe that? Would you?"

"Ha! Hey, no ellipses—say something!"

The system went completely silent soon after.

As if nothing had happened.

I kept calling it, promised not to pry into sensitive personal details, coaxed and begged it to come back out...

"...Hey, I won't ask anymore. I don't even care who you are."

Still no reply.

"I wanna get along with you. Hey, you listening?"

There was definitely something there.

I was just frustrated not knowing what.

I ended up yelling like a madman until I wore myself out.

To soothe my frustration, I headed to the kitchen.

It was about time for breakfast anyway.

My throat was parched; I wanted some water.

"...You up?"

"Y-Yeah."

Mom—who I'd been rolling around in bed with—greeted me casually.

And at the table sat Younger Sister, prim and proper-faced.

"Where's Sis?"

"...Said she wasn't hungry."

"Oh?"

I wondered if it was because of me, but yeah, that could happen.

Time would sort it out. Right now, across from me was Younger Sister, who kept sneaking glances like a dog desperate to poop.

I'd had no appetite until moments ago either, but facing Younger Sister made my mouth water profusely.
