Chapter 19: The End
“I can’t believe my little sister is so cute… it’s just… unbelievable.”
“What’s gotten into you all of a sudden…”
“Haha, it looks like you’re feeling refreshed.”
Well, I definitely feel refreshed.
Lately, I’ve been in a much better mood than before, and Toshinobu, Rikiya, and even Shinozaki-san have been approaching me more often.
“Hehehe~”
“Hey, what the hell happened!”
“Well, isn’t it great? Have you finally recovered?”
“Don’t you dare mention Myuu anymoreeeee!!”
While I thought the two of them were being noisy behind me, I looked back on what had happened recently.
It’s been about two weeks since Miu and I officially started dating, and it’s about time for summer vacation.
For now, we’ve only informed our relationship to our parents, and they both genuinely congratulated us. They were grateful that Miu became my girlfriend and that she was warmly accepted into our family, and they shed tears of joy for her.
“I’m so glad… I’m so glad…!”
Miu cried… without mocking her in the slightest, I held her tightly in my arms… but being so overjoyed like that reminded me that I could never betray her, even if it meant my life.
Well, betraying her is absolutely out of the question… If something like that were to happen, Mom and Dad would kill me.
(…There really hasn’t been much of a change, huh?)
What surprised me was that these past two weeks, nothing particularly different happened with Miu.
I had high expectations… Yeah. I know there’s no point in hiding it, so I’ll say it. Since Miu, who always made advances in a sexual way, became my girlfriend, I thought there would be all sorts of things that I couldn’t even put into words… But it seems that Miu is incredibly satisfied with our current relationship, and she’s just happy sticking close to me without wanting anything more, as if thinking that wanting more would bring punishment upon her.
“Hahaha… Well, I guess that’s true. I’m satisfied with just being happy♪”
Seriously… I can’t help but find my little sister incredibly cute.
Not that she doesn’t try to seduce me at times, as she still casually presses her body against mine… Well, I’m satisfied with just that.
Just having my beloved girlfriend by my side already makes me happy, so it’s only natural that my heart feels fulfilled when she expresses her affection in such a way.
“Seems like things are going well, judging by your expression.”
“…Well, yeah.”
I nod to Rikiya, who seems to have figured it out to some extent.
We haven’t explicitly stated it, and both Miu and I continue to behave as usual at school, so no one would even think that we’re dating.
Of course, when we meet at school, we talk like regular siblings, but our restraints are generally released when we return home.
(I can’t wait to go home and cuddle with Miu… Ugh, I never thought I’d have days where I’d think like this.)
I truly mean it.
However… I believe that as an older brother and boyfriend, I shouldn’t be satisfied with just this. From now on, I’ll do my best to protect her… to protect Miu.
Maybe things won’t change much from before… but more than ever, I will love and protect her… absolutely.
“…It’s a story of how much I love her.”
So, I really want to see Miu soon.
And then, nothing special happened for the rest of the day. Time passed without any particular event. Maybe it felt more relaxed because I was thinking about Miu… After the closing ceremony, I quickly left the classroom and met up with Miu at the school gate.
“Nii-san.”
“Yeah?”
“I really want to hold hands. I want to cuddle. I want to kiss.”
“…Your relentless advances are quite pleasant.”
“I want you to touch my breasts and other things.”
“!?”
…Well, even though we don’t actually do those things, Miu freely says things like that, and each time, my self-control is tested.
While exuding such sweet vibes with Miu, we finally arrive home and our time together begins.
“Nii-san!”
Miu tightly embraces me.
Lately, as soon as we come home, it’s always like this. After taking care of things like bathing and dinner… except for bathroom breaks, Miu is basically attached to me like this.
It’s not constantly, but I’ve considered the possibility of feeling annoyed by it… but anyone can see that it’s utterly meaningless considering my current state.
“…I’m happy.”
Yes, there are no other words that come to mind besides happiness.
However… I did notice that Miu had a different expression today, as if she had a hidden determination. But after that, I didn’t see that expression anymore, and it was just a normal night getting ready for bed.
Tomorrow is a day off, so we don’t plan on sleeping yet. Miu also said she still wants to talk a lot with me.
“Hey, Nii-san.”
“Yeah?”
“Tomorrow is a day off, right? I’ve been thinking, maybe today is the day for me and Nii-san to do that…”
“Do… do what?”
Do what…
“You’re pretending not to understand even at this point? I want to have sex with Nii-san.”
“…”
…What is this sensation of my brain being shaken by her direct words?
She’s grinning as if teasing me, but I can tell that her cheeks are even redder and she’s more embarrassed than usual.
“I… Recently, I’ve been so incredibly happy and satisfied, but of course, I’m always thinking about that kind of thing, you know.”
“… Ou.”
“And Nii-san, well, you seem like you can’t resist, right?”
That’s… certainly true.
However, I won’t just go along with the situation. Instead, I decided to convey my determination or rather, my feelings to her.
“I also want to do those things with Miu… So I promise. I’ll continue to love and cherish you more than ever, Miu. I love you.”
“Yeah! I love you too!”
By the way, I hadn’t actually thought I would go this far.
But when Miu suddenly took out a square packet from somewhere… at that moment, I understood how serious she was, and from there, there was no turning back.
A few hours later, Miu and I were embracing each other naked.
“That was amazing…”
“Yeah.”
If I had to express my thoughts in one word, it would be “amazing”… It’s definitely an embarrassing act, but I felt like I could love Miu even more, and my feelings for her became even stronger.
“You know… I was really aggressive and all, but deep down, I never thought I’d end up in this kind of relationship with Nii-san. I always thought there would be someone better for you than someone like me.”
“Just how amazing am I in your eyes?”
“You’re amazing… You’re an incredibly amazing big brother. But you know? That’s why I thought—I absolutely have to become Nii-san’s girlfriend. I have to completely captivate you… Because I’ve fallen in love… Because I can’t see anyone else but you, Nii-san.”
“…”
Under the intense gaze I received, I was momentarily speechless, but I quickly stroked Miu’s head.
“If that’s the case, then you’ve definitely completely captivated me… Because we already have such an obvious relationship.”
“Hehe, that’s right♪ By the way, Nii-san.”
“Yeah?”
“Can I do the same things as the little sister in that manga? In fact, let’s enjoy the same situations as if we’re reenacting it?”
“!?!?”
That was truly a devil’s whisper.
Although I’m happy with anything that involves Miu… when she hints at recreating my beloved manga, my heart trembles uncontrollably.
…Well, but in the end, having her by my side is the best thing.
“No matter what, as long as Miu is by my side, I’m happy.”
“I want to be by your side forever, Nii-san.”
“Of course. No matter what happens, I’ll be by your side… I promised to protect you, Miu.”
“Yeah. I love you, Onii-chan♪”
Embraced by her smile, warmth, and the supreme tenderness… as our first night together passes… we made a vow to never be apart.
Becoming both siblings and lovers, even if it’s just in name… I feel happy that it’s Miu. From now on, I will continue walking the path with her, day by day.
[Afterword]
And that concludes this work.
Originally planned as a medium-length story, I think it turned out to be a good length.
Writing about a naughty gal little sister… It was truly enjoyable even as I was writing it (lol).
Thank you all for reading.
TLN-
Aye, thank you all for reading. See you in some other work.
