Do Not Trust the Little Sister
1. Don't trust your little sister. And... something strange started floating into my field of vision.
1. Don't trust your little sister.
2. Don't trust the 'little sister'.
4. Unconditionally fulfill your little sister's requests.
5. Escape to the real world.
6. If item 3 is blank, don't trust item 4.
7. Wake up wake up wake up wake up KIIIIIIING─────
KIIIIIIING─────
Zzzzt- Zzt-
Static noise piercing my ears...
"Guhhhhhh!!"
My vision warped and fizzled like an old VHS tape stretching out.
Thud!
My legs gave out, and I collapsed to the floor.
The 'little sister' rushed over in shock.
"O-oppa? Oppa, what's wrong? Huh? O-oppa? A-are, are, are you okay? Huh? I,I,I went t-too far, right? Huh? S-so-so-sorry sorry sorry sorry sorry sorry sorry!"
She trembled like an aspen tree and hugged me tightly.
Huuuuh─ Haah….
Inhale.
Exhale.
It stabilized.
The tension that had pulled me taut like a bowstring loosened, and my mind relaxed.
And through the gaps in my loosened mind, her body heat seeped in.
Small body.
The soft, squishy feel of her modest breasts.
"Smells... nice..."
A pleasant fragrance wafted from her hair.
A thick lavender scent filled my head, overpowering the smell of my own cum.
We used the same shampoo, so how did it smell like this?
"Uh, y-yeah? Y-yeah, it does! Ehehe! A-anyway, you're okay, right...? Huh? You're fine, right? Sorry, Oppa... I just wanted to see you cum so bad... So I got too eager, I guess..."
"Phew... Yeah. I'm fine now. Probably just got dizzy from cumming so much."
"Hing... Sorry, Oppa. From now on, I'll hold back a little on the 'requests,' okay?"
Requests...?
Ah.
She meant that cold command earlier: 'Cum.' 'Shoot your semen.'
"Y-yeah... Sure..."
"Ehehet♡ Oppa is the best♡ Your cum was so thick and manly today, it was awesome! The best! M-might've fallen even harder for you. So, chu♡?"
Mwah♡ Smooch♡ Kiss kiss♡
She showered my cheeks and lips with kisses indiscriminately.
Come to think of it, it felt natural on the bed earlier, but... was mouth-kissing normal between real siblings?
Smooch...♡
Chuu...♡
Lick...♡
"Heeung...♡"
As I sat there dazed, her tongue grew bolder.
Like a couple in afterglow after sex, her small tongue lovingly licked my lips.
Thud─
No, this was wrong.
I grabbed her shoulders and pushed her away without thinking.
"......Huh?"
She stared at me with a blank expression, as if she never expected me to push her away mid-kiss.
"Wh-why...?"
Her eyes shook with anxiety.
Putting some distance let me escape her scent, and my head cleared again.
"Sorry... Not in the mood right now."
"Ung...? Ah, aa~ That post-nut clarity thing? Fuhihi... Fine~ I can understand that much."
It was a slightly different misunderstanding, but still a relief. If she'd pressed further, I wouldn't have had an excuse—my head felt completely empty.
She brushed herself off and offered me her hand.
"C'mon. Let's head back. Today’s just first period, they say."
They say?
Who?
In an empty, pitch-black school at 1:30 a.m.... who told you that?
And for that matter... are you and I even students?
But I couldn't voice it.
Her strangely swirling pupils felt like they were piercing right through me.
"Yeah, let's go home."
Thud thud.
Creak─
Our parents had already gone to bed when I opened the front door.
Fast.
They'd been so engrossed in eating when I left.
In the short time I was gone, they'd finished, cleaned up, and even done the dishes?
So diligent.
"Ah... I'm tired even though it's not long since I woke up."
"Then sleep~"
"Gotta wash up first. You not washing?"
She chewed her lip—her habit when pondering.
"Huuung... I should, but... still... it'd be a waste to wash off Oppa's cum."
"Doesn't it feel gross?"
"Gross? No way! It's not every day I get a full load in my panties..."
"You know how bad cum smells after a day, right? Wash it and sleep properly, or you planning to sleep in those cum-soaked panties?"
"Ung. So? I'm gonna sleep stuck right to Oppa's cum♡"
I couldn't stand it.
"That's weird! What little sister in the world catches her big bro's cum in her panties and sleeps wearing them?"
"Ha...? W-weird...? Really...?"
She tilted her head sideways and glared at me.
Her eyes gleamed like a wild beast's in the dark, piercing through mine and churning my brain.
"It's not weird. A little sister naturally wants her big bro's cum. Not weird. It's normal. Big bro naturally provides cum to his little sister... When she wants it, he diligently buuuu♡sts his precious load for her. Got it?"
Zzt─
U-ugh... Guh....
"Answer me."
"Y-yeah... It's n-normal... Yeah.."
Half my brain still screamed it was wrong, but I suppressed it.
One more of those 'requests,' and I'd really lose my mind.
Squish..♡
As I stood confused, she hugged my chest.
Her face buried around my solar plexus looked adorable due to her small frame.
"Oppa seems kinda weird today... Hing... Fine, Oppa. I'll wash the panties and shower then. Happy?"
"Y-yeah, good call."
Relief.
Even if family skinship was normal to that extent, the idea of my little sister sleeping in panties soaked with my cum felt oddly gross.
But her words didn't end there.
"Instead! I get the first cum tomorrow morning?"
"What?"
"Jeez, tired or something? It's normal to wake Oppa with a chu♡ in the morning, and if you have morning wood, take care of it!"
She hadn't said that earlier.
But when she phrased it so nicely, better to just accept.
"...Got it. First load tomorrow... yours."
"Yasss!! Uhehehe! Oppa, I'm off to wash!"
Dododo!
She dashed upstairs to her room's bathroom with nimble steps.
On the stairs she'd run up trailed traces of my cum... and clear fluids.
"Guess I should wash too."
I headed to my room's bathroom.
I wanted a shower, but I was drained.
Just rinse and crash. I barely washed my lower half, opened the door—
And jolted in terror.
"Oppa."
My little sister sat on my bed, her red eyes gleaming as she stared at me. Was she here to mess with my mind because of my unusual behavior today?
