"Onii-chan? Still sleeping? Heave-ho~"

A strange weight pressed on my body. Groggily, I opened my eyes. An odd bulge shifted under my blanket. Something wriggled out—a young girl with long, flowing black hair. Half-asleep, I couldn’t quite recognize her.

But she felt oddly familiar.

"How much longer will you sleep, Onii-chan? It’s already noon! Get up fast, or you’ll miss Chuwei’s panties set meal~"

Chuwei?! My sister?! That sweet voice came from her?! I must be dreaming!

"Will this wake you up, Onii-chan?"

Her cute face leaned close. It hovered near my cheek for a moment. Then—"chu~"—Chuwei’s soft lips brushed my skin, leaving a sweet, strawberry-like mark.

"Awake now, Onii-chan?"

Chuwei grinned mischievously. A blush slowly spread across her cheeks.

My drowsiness vanished. I realized Chuwei was naked under my blanket. Her soft legs trapped my left leg. Her knee pressed against a very sensitive spot.

"Hehehe... Only a sister’s morning kiss wakes a sleepy Onii-chan! Childhood friends? Girlfriends? Nothing beats a sister, right?! Onii-chan~"

Chuwei stretched slender fingers. She traced circles on my chest. Deliberately, she swept aside her hair. Her whole body lay exposed—

"Hurry up, Onii-chan! I saved my bathwater for your mouth rinse! And yesterday’s panties are in the basin as your washcloth!"

Sugoi! A sister’s panties and bathwater are perfect!!!

"And... Onii-chan—it’s almost noon. What lunch do you want?"

Chuwei’s face flushed crimson, even her ears glowing. She gazed at me tenderly.

"Panties luncheon meat set? Panties steamed soup? Or... me?"

Wasn’t that obvious?! No need to choose! What was I waiting for?! I tried flipping to pin Chuwei down. Dizziness struck—

"Ugh—"

My head hit the floor.

"Just a dream? Phew..."

Wait?! Why such a messed-up dream?! Did I suddenly awaken my siscon soul?! No—daytime thoughts shape nighttime dreams. No one dreams this randomly! Could I... really have improper feelings for my sister?!

"Ah—impossible!!"

"Shut up so early, will you?!"

A girl’s furious roar echoed outside. My shouting must’ve angered my sister. The door kicked open violently. Chuwei stood there in pink onesie pajamas, hugging a Kumamon plushie. Her hair was messy. Seeing her without twin tails felt nostalgic.

"Stop acting crazy at dawn! What were you doing?! So loud! Do you know it’s only five o’clock?!"

Chuwei scolded me like I’d killed her father. Seriously, you’re louder! Neighbors will wake up!

But that dream left me flustered. My lower half throbbed. I yanked a pillow to cover myself.

"Knock next time! Get out now! Just get out!"

I yelled to hide my state, hoping she’d leave. Instead, she stepped closer.

"So energetic this early—you?! Pervert! Unbearable!"

Chuwei stomped on my pillow. Hard. Repeatedly. She knew exactly what she was doing.

"Stop it! Get out now?!"

She noticed my flushed face. I turned away, hiding it.

"Oh ho? Excited by this?! Disgusting brother! Stepping on a beauty thrills you?! Fine—I’ll bless you more!"

Chuwei pressed harder, widening her steps. True, she was grinding on my member through the pillow.

I snapped. I shouldn’t roughhouse my sister, but my dignity was gone. I yanked the pillow. Her foot slipped. She crashed down. Her nightgown flipped up. Accidentally, I saw her underwear—blue and white stripes? What the heck?!

I bolted out, ignoring her furious curses. After this demon-sister hassle, it was 5:30. Beautiful girls are annoying!

Later, Chuwei acted normal. As if nothing happened, she washed up, strolled to the living room, and turned on the TV. Seriously, TV this early? Bad for your eyes!

I almost warned her. But after yesterday’s behavior and this morning... mostly my dream... I stayed silent.

"Pervert! Make breakfast now!"

Chuwei ordered coldly. Our parents hadn’t returned all night. I sighed, shook my head, and headed to the kitchen. How many times had this routine repeated?

"Morning’s my fault?! Normal biology makes it weird not to happen! You—don’t act like an ero-game heroine on your own!"

"Oh ho? So you see me as an ero-game heroine?! Sick thoughts about your sister? Pervert!"

Chuwei’s face stayed calm, but her insults cut deep. She grabbed milk, poured only one cup, and shoved the carton back. Ignoring me?! I need some too!

"Your interpretation—I never said that! You acted first, then called me perverted. Who’s cruder...?"

Chuwei fell silent. She realized her teasing was wrong. Her face burned red. That ero-game act must’ve been accidental... but way too far!

After that, Chuwei ate breakfast wordlessly. I checked the clock—running late. Skipping my meal, I grabbed bread and changed shoes at the entryway. Behind me, my sister’s incredulous voice rang out—

"Oh ho—you have a girlfriend?!"

"You asked last night! Joking now?!"

"Why rush out so fast?!"

"None of your business!"

Yes. This was our home’s start. Our daily life’s beginning. I walked out without looking back. I didn’t hear Chuwei’s last whisper:

"I specifically reminded you last night, stupid brother."
