Volume 1: Chapter 3 – Part 7Author: Geraint
With my parents gone on vacation overseas and taking Fuyumi with them, I suddenly found myself with nothing to do. Normally, I'd be looking after my baby sister. Now, I was just sitting on the couch, staring at a box of condoms—one my dad had intentionally left behind.
He was the one who encouraged me to... get closer with my step-sisters while they were away. But I hadn't even confirmed their feelings for me yet. What if they hated me for even bringing it up?
"I'm home!"
Shiina's voice called from the front door. I jumped and immediately shoved the box into my pocket.
"Welcome home!"
I turned to greet her, surprised that she was alone.
"Huh? Where are Yuuka and Lilith?"
"Yuuka's got training today for her performance this weekend, and Lilith went with her as a bodyguard."
"I see."
That's when I noticed something odd.
"Did you roll around in the park? You've got leaves in your hair."
I got up from the couch and approached her, gently picking the leaves out of her long hair. She froze, her face turning bright red.
"U-Umm… There was this cute cat I saw and… I followed it into the bushes. I just wanted to pet it, but it ran away."
"You shouldn't wander off like that. It's dangerous to walk around alone—especially for a girl."
"Seir-kun! I'm already in high school. Stop treating me like a child, like my mom does! I can take care of myself!"
"I am treating you like a lady. You're really cute, and I wouldn't be surprised if guys on the street took an interest in you. Next time, just call me if you're heading home alone, alright?"
Her eyes widened as she looked at me.
"Wait… Can you say that again?"
"Huh?"
"You said I was 'really cute.'"
"It's true. You are."
Her face turned even redder. "I-I'm going to change!" she squeaked, rushing past me and holding her hands over her blushing cheeks.
When she came back, she was wearing a white sleeveless blouse and a blue skirt—her usual loungewear. She sat beside me on the couch and slowly leaned against me, resting her head on my shoulder, just like she always did.
After a while, I asked her quietly, "Hey, Shiina. What do you think of me?"
"…What?!"
"I mean, am I just a childhood friend to you?"
"W-Why are you asking that out of nowhere?!"
I wrapped my arm around her waist and looked into her eyes.
"What's your answer?"
"You're being unfair, Seir-kun. You'd know if I lied. I… I still can't answer that."
I leaned in closer, staring at her lips. She trembled but closed her eyes, waiting. Her breathing was soft, expectant.
"Seir-kun…"
Our lips were just about to meet when—
"What are you two doing while I'm gone?"
Yuuka's voice sliced through the moment like a blade.
"Gyaaaaah!" Shiina shrieked and shoved me away, her face redder than ever.
"Yuuka?! Weren't you at training today?"
"I skipped."
Her tone was menacing. Behind her, Lilith stood frozen with a pale expression.
"E-Eh? Why?"
"Mom messaged me. She told me the three of them went on vacation, and Onii-sama would be alone at home. I had a bad feeling about it… and I was right! You two were just about to kiss!"
"Wait! Yuuka, let's talk about this!"
"What's there to explain? I saw it with my own eyes!"
"I—I'm sorry!" I bowed my head in surrender.
"Huh? What's this?"
She picked up the item that had fallen from my pocket.
My blood ran cold.
"Onii-sama… isn't this—?"
Her face turned red as she held it up.
"You PERVERT! This is a condom! Were you planning to use this on Ayaka?!"
Shiina's face turned pale.
"S-Seir-kun… is that true?"
"I HATE YOU, YOU SCUMBAG TRASH!" Yuuka screamed as she ran upstairs, slamming the door shut behind her.
"Seir-kun… we need to apologize to her," Shiina said gently.
"No… This is all my fault. You didn't do anything wrong."
"But still…"
As I was thinking of how to fix things, Yuuka came back downstairs, now dressed in a sleeveless, frilly white dress that barely reached her thighs, with black shorts underneath.
She was still glaring, but quietly sat on the other side of me and leaned back against my shoulder.
"Yuuka…?"
"I told Mom what happened. She got mad at me instead."
…Seriously?
Yuuka pointed at Shiina with trembling hands.
"Listen up, Ayaka! You're a servant in this house, just like your mom! You're not allowed to do anything with Onii-sama without my permission!"
"I—I'm sorry, Yuuka-sama!" Shiina bowed deeply.
"Hey, that's my fault," I tried to explain. "I was the one who—"
Before I could finish, Yuuka grabbed my head and kissed me.
"W-Waaaah…" Shiina gasped.
Yuuka pulled back, her cheeks flushed.
"All of Onii-sama's first times should be mine. I go first—before her."
"Should I take that as a confession?"
She nodded shyly.
"You dummy. It's been obvious from the start. Ever since you saved me… I fell in love with you."
"What about your idol career? Aren't you not allowed to date?"
She sighed and rested her head on my shoulder.
"I'm planning to graduate soon. I've already achieved my dream. Staying in the industry forever isn't for me. The management keeps pushing me to do gravure shoots, but I refuse. I won't sell my body just to stay relevant. Besides—I'm the daughter and heir of Laurier Enterprise. I don't need the money."
"…Okay."
"You should be thankful to have such a loving girlfriend. Lilith told me how you two survived after arriving here. You fed her insects, didn't you?"
"Uuuuugh…"
"Don't worry, Onii-sama. I'm done being an idol. What I want now is to pursue my happiness… and that's becoming your wife."
She smiled sweetly. I leaned in and kissed her this time.
"Onii-sama…"
Our lips locked in a deep, passionate kiss.
When Yuuka finally pulled back, she glanced at Shiina, who looked heartbroken.
"Sorry, Ayaka. Looks like I took his second too~" she grinned.
"Umm… It's fine. I think I'll be going now…"
"Where do you think you're going?" Yuuka raised an eyebrow.
"Eh?"
"It's your turn. Go kiss him already!"
"E-Eh?!"
I turned to Shiina and gently wrapped an arm around her shoulders.
"Wait—I'm not ready—!"
Too late. I leaned in and kissed her, her eyes going wide. She trembled in my arms, but eventually her lips parted and our tongues intertwined. When I pulled away, she was panting softly, her face burning red.
"H-How was it, Ayaka?" Yuuka asked.
"I-It felt… good…" Shiina admitted, flustered.
"Let's sleep together tonight. And leave that pervert here."
Yuuka grabbed Shiina's wrist and pulled her away.
"Wait! What about me?!"
They both turned to me with mischievous smiles. Yuuka whispered something in Shiina's ear, and they nodded in unison.
"No perverts allowed~."
