When We Found Out We're Not Blood-Related, My Little Sister Became Seriously Love-Brained ~When a Little Sister Stops Being a Little Sister, the Ultimate Heroine Emerges!~

Chapter 9: The Chocolate’s Afterglow Doesn’t End

In the dimly lit room.

The silver foil on the table rustled just once.

What time is it now?

It was already past midnight.

Apparently I fell asleep while getting a lap pillow.

On my chest, Suzune’s bangs sway with the rhythm of her breathing.

The aftertaste of chocolate still lingers under my tongue.

Last night, I said “I love you.”

Guilt, and an equal amount of satisfaction.

…Even if I make excuses saying it’s the chocolate’s fault, it’s probably not true. When I put my hand in my pocket, the memo touched my fingertips.

Our yesterday hasn’t ended yet.

※

“Mmm. Munyaa.”

When Suzune moved her left arm, she said something in her sleep.

Her left hand seemed to be searching for something, so I held it. Then Suzune smiled.

What kind of dream is she having?

It’s been a while since I’ve seen Suzune’s sleeping face.

Maybe since we were kids.

I lifted my head and peered at her.

Suzune’s sleeping face after so long was younger than I thought, and very peaceful.

—I feel drawn into those fresh lips.

(Should I kiss her?)

I quietly brought my face closer.

No, but.

If I do it, I want her to properly remember.

As I hesitated at a distance where we were almost touching, Suzune started moving around.

Her eyes are about to open.

A lot happened earlier, so it’s awkward.

I’m embarrassed to face her, so I decided to pretend to be asleep.

I squeezed my eyes shut and turned my back to Suzune.

“Mmm, mm.”

Suzune sat up.

That was close.

I almost would have met her face-to-face while in kissing position.

Since my back is turned, I can’t see Suzune’s situation. I want to turn around, but if Suzune’s face is right there, it would be, well, troublesome.

After that, Suzune didn’t move for a while. When she moved away from me, my right shoulder area immediately sank with weight. Hair fell on my temple with a flutter, and I smelled the sweet scent of chocolate.

Apparently, Suzune.

Is on all fours over me.

I squeezed my eyes shut.

With Suzune’s movements, her hair slides smoothly down my left cheek.

※

What is Suzune doing right now?

Suzune’s arm touched near my ear, and when the area sank with pressure, this time breath hit very close to my face. A slightly adult-like sake scent.

“Hey. Onii-chan. Are you awake? Hey, hey.”

Suzune’s voice is close.

“You’re sleeping, right?”

After confirming I didn’t respond, Suzune started talking to herself.

“You know, I like you.”

Suzune stroked my cheek.

“If you’re sleeping, it’s okay to say it, right?”

When Suzune brought her mouth close to my ear, she whispered.

“Onii-chan, I like you. Onii-chan, I love you. Yuuma, I really, really like you.”

The monologue continues.

“Hey. You might feel hesitant, but I liked you as a boy even when you were my onii-chan, you know?”

Huh. This girl.

Is she seriously a brocon?

“So you know. I like you twice as much. Hey, are you listening? If you heard that, I might die of embarrassment.”

From this statement of Suzune’s.

She shouldn’t dream that I’m awake.

※

It’s no longer permitted to open my eyes now. I have no choice but to get through this by pretending to sleep.

Suzune continued speaking.

“But you know. Finding out we’re not blood-related made me sad. But you treat me more preciously than before. …I’m happy. Since we’re not blood-related, I can become your bride too.”

“Ugh. Yuuma fell asleep, how boring. Oh!”

“I’ll play a prank. It’s bad to be sleeping, so it’s okay, right? Hehe. Should I kiss you?”

This girl is doing whatever she wants thinking I’m asleep. Mine is also an important first kiss though…

Creak.

The sofa creaks.

“…………”

However, contrary to expectations, Suzune didn’t do anything. And when I let my guard down.

Smooch.

I was kissed on the cheek.

“Yeah. It’s not good after all. Doing it without permission while you’re sleeping.”

As expected of a serious girl.

“Also. Sorry. I’m not very cute. If I was a cuter girl, Yuuma would definitely say he likes me, right?”

This is surely Suzune’s true feelings.

When it’s just me and her she says beautiful girl and such, but I’ve never seen Suzune talk about her own appearance when she’s with other people.

I once heard somewhere that “real beauties are surprisingly not confident in their appearance.”

Maybe Suzune is like that too.

If she’s not confident, I should have told her more that she’s cute.

※

“Well, Yuuma doesn’t seem shallow, and he’s kind so it’s fine!”

Your brother is actually always just looking at girls’ faces. Sorry.

Suzune changed her position.

The sofa creaks again.

Heated breath hits my neck. Apparently Suzune is pressing her nose to my neck.

“Ahh… I really like this smell. I can’t usually smell it, so this much is okay, right?”

Suzune moved a bit lower.

Sniff…

This time Suzune’s chin touched around my armpit.

“This is bad. I might get excited…”

Is this person a smell fetish?

This is way more embarrassing than a kiss.

“Kei said before that the person you like has a good smell, and it’s true.”

Suzune stopped moving.

“…………”

(The silence is scary. What are you planning to do?)

※

After a while, my cheeks were patted.

“Hello. Are you awake?”

Suzune said in my ear.

I continued pretending to be asleep.

I can’t wake up now.

“Yuuma said I don’t excite him, but I wonder if that’s true.”

Suzune’s center of gravity moved toward my lower body.

No way…

To confirm, is she going to visually check?!

Suzune’s breathing is rough.

Clink clank.

Suzune is trying to undo my belt.

Suzune seriously intends to take them off.

I might have to wake up prepared for awkwardness.

Creak…

Suzune’s movement stopped.

“It’s not good after all, right?”

Thank goodness.

Did she reconsider?

“But I can only do this now. Unfairness isn’t good, right?”

“Heave-ho.”

Fabric floated down onto my face.

“I’ll take mine off too, so we’re even. Hehe. Too bad you’re sleeping.”

W-w-wait.

Is this Suzune’s panties?

My little sister is pointlessly too earnest.

(Seriously? So right now Suzune is going commando?)

This makes it even harder to wake up.

※

“Oh, a heartbeat?”

Apparently she heard this wildly raging pulse.

Suzune pressed her ear to my chest.

“Amazing. It’s pounding. Yuuma’s heart is pounding for me too. I’m so happy.”

A sweet, small, happy-sounding voice.

Suzune didn’t move for a while.

(You’re done now, right? About time to stand up?)

But my faint hope was betrayed.

“This is bad. I’m so emotional, I can’t hold back. I wonder if I can do this well.”

(So what are you going to—!?)

Suzune straddled around my thighs and put her hands on my underwear.

It’s so swollen like this.

If she sees it, I feel like I’ll go crazy.

Could it be that I’m.

Having my first experience today?

And my partner is my little sister.

No, this is bad.

If this happens, I’ll hurt Suzune.

※

At that moment.

Rattle rattle.

The sound of the entrance doorknob moving.

Ding dong.

The intercom.

(Did someone come?)

“Huh… What should I do?”

Suzune stood up.

There’s a rattling sound like a key being inserted into the keyhole.

(Oh no. It’s our parents. Earlier than scheduled.)

Then Suzune grabbed and recovered the panties from my face.

“Onii-chan, sorry. Good luck! Also, I ate the chocolate without permission, so please destroy the evidence too!”

Suzune said that and ran up the stairs.

Seriously, that girl.

She ran away by herself.

※

The sound of the entrance door opening.

I need to escape too. This is no time to be sleeping.

I gathered the chocolate wrappers and stuffed the whole box into my pocket. Then with my free hand I held my belt so my pants wouldn’t fall down as I stood up.

“Are you two here? Plans changed early. I bought souvenirs.”

Saying that, both parents entered the living room.

I made eye contact with Dad.

“What are you doing?”

Dad looked at my pants and said.

“N-no. This is…”

(What excuse should I make? I’m seriously done for.)

Then Mom clapped her hands.

“Oh, maybe you ate too much and got uncomfortable? Your father often takes off his belt after meals too.”

“I-I see. Yuuma, you’ll catch a cold, you know?”

Dad said that and returned to their room. Mom also winked and followed Dad.

I’m curious about the meaning of the wink, but I’m really saved. Thanks, Mom.
