“Well, if you get together with those girls, I’ll have three cute little sisters!”
 
Ah… so there was that kind of ambition after all.
 
But my sister is really cheering me on from the bottom of her heart… and above all, because she loves Matsuri and the others too, that’s why she’s saying all this.
 
“That said, you’ll probably have to hide it to some extent, so if anything comes up, come tell me anytime. I’ll help you all.”
 
“Yeah!”
 
Seriously, thanks nee-chan!
 
When I hugged my sister tightly to show my joy and gratitude with my whole body, I … Read the rest

Chapter Five: I’m Gonna Confess My Feelings

Several days have passed since my date with Saika.
 
Ever since then, I’ve been thinking about my feelings, but the more I think about it, the more one answer occupies my mind… I want to be with them.
 
“…Mmm.”
 
And today too, I’ve been thinking about it since I woke up early in the morning.
 
“Hey partner, what do you think?”
 
When I speak to my phone, text appears once again.
 
『Why don’t Master do what you wishes? That choice is what you want, and what they want too』
 
“Well, yeah, but…”
 
By … Read the rest

“Saika.”
 
“Yeah… ah.”
 
When getting off the boat, Saika lost her balance.
 
My body moved faster than I could think in my head that nothing must happen to Saika.
 
I extended my arm to support Saika’s body and rather forcefully pulled her to my chest.
 
“You okay?”
 
“Y-yeah… ugh.”
 
The receptionist hurried over looking flustered, but we immediately told them we were fine and left the spot, sitting on a bench in the shade of a tree.
 
Just in case, I carefully watched Saika’s condition on the way here, but she didn’t seem to have injured anything in particular, so … Read the rest

“Hey, there’s still time left… we can still do various things.”
 
“Various things?”
 
Saika nodded and put her fingers on the zipper at her neckline.
 
The moment I thought “no way,” Saika slowly lowered the zipper… she stopped right below her chest.
 
“H-hey…!”
 
T-this way of undressing… if I see this up close, the destructive power is insane!?
 
The destructive power was already tremendous from the start, but with this, Saika is completely trying to kill me.
 
In other words, what I’m trying to say is, the level of eroticism just skyrocketed.
 … Read the rest

“There are so many different kinds.”
 
“Yeah… wait, why are we here, Saika?”
 
“Because Kai-kun seemed interested.”
 
So she noticed after all!
 
As if saying she can see right through my thoughts, Saika smiled and looked around the shop curiously.
 
“I’ve never come to a shop like this, so I’m actually excited.”
 
“Really?”
 
Seems Saika is like me—this is her first time in a shop like this.
 
Although it’s not a shop that everyone visits, there are a fair number of people browsing costumes out of interest like us, and they seem to be enjoying themselves.
 
“…Ah, this is—”
 
As … Read the rest

“Saika!”
 
“…Ah.”
 
I raised my hand and rushed over to Saika.
 
The moment she confirmed my figure, Saika changed from an expressionless face to a smile, and she rushed toward me too… wait, bouncing breasts!?
 
When someone with explosive breasts like Saika runs, naturally her chest bounces!
 
Even though it’s summer vacation, today is Saturday, so there are many people around—quite a few gazes turned toward Saika.
 
“Whoops…”
 
“…Caught you.”
 
Saika gripped my hand tightly and stood next to me.
 
Saying she caught me was pretty cute, but the smile she showed right beside me was even cuter.
 
“…………”
 
However… … Read the rest

Chapter 4: A Date with Saika!

 
[Kai-senpai, thank you so much for today. Ever since I got home, I haven’t been able to stop thinking about Kai-senpai and Miyako-san… It was truly that enjoyable.]
 
When I returned to my room after dinner, that message was waiting for me.
 
The sender was, of course, Emu who had come over today. She’d said the same thing when I saw her off at her house, but I’m really glad she enjoyed herself.
 
“…Man, that was really fun.”
 
There are many reasons why I found it enjoyable, but for me personally, the fact that … Read the rest

“I’m back. Here, let’s have some ice cream.”
 
“Ah! Thank you very much!”
 
Emu received the ice cream with a smile and slowly put it in her mouth.
 
“It’s cold and delicious♪”
 
“I’m glad.”
 
Satisfied with Emu licking her ice cream with a smile, I started eating mine too.
 
The summer companion has to be ice cream!
 
Both big sister and I love it, and we especially prefer soda-flavored ice cream.
 
“…So good.”
 
“It’s delicious♪”
 
“What flavor do you like best, Emu?”
 
“Ice cream? Let’s see… I like soda flavor of course, but I also like matcha flavor.”
 
“Ooh, how … Read the rest

Emu doesn’t seem entirely opposed either, and she embarrassedly hugs my sister back, looking somewhat interested.
 
“…But.”
 
Looking at this, my sister really looks more like the little sister.
 
The interaction between Emu and my sister is certainly a feast for the eyes and undoubtedly a healing sight… but my sister is definitely the little sister here.
 
“Is someone like me really good enough to be your little sister?”
 
“Don’t say ‘someone like me.’ If Emu-chan became my little sister, I could dote on you together with Kai!”
 
“Dote on me… Miyako-san will dote on me.”
 
“That’s obvious! Ahh… you’re … Read the rest

Chapter Three: Emu Comes to My House!

“Hey Mom, what do you think?”
 
“Well… something good must have happened, right?”
 
“Yeah, that’s probably it. Now then, what has my little brother been up to?”
 
“He’s at that age, so don’t pry too much.”
 
“Okay~”
 
“…………”
 
Ugh, shut up…!
 
For a while now, the warm gazes of my sister and mom staring at me with those grins have been really annoying, you know!?
 
“Don’t look at him like that. Even Kai must have one or two secrets he wants to keep.”
 
“Dad…!”
 
My father!!
 
I was deeply moved from the bottom … Read the rest
