Parents remarried. Now my lover starts referring to me as "Onii~chan" - Chapter 3 Part 3

“What are you doing…?”

I asked in confusion.

“No! Th-This… this is just a little, yes, a slight improvisation!!”

A startled Neneka turned bright red and hid her chest area with her arms.

–Did she wear my Y-shirt on a whim?

No, no, instead, it was way too cute…!!

Was this the rumored Kare-Shirt?

Why did she look so cute even though she was wearing a baggy shirt like a one-piece?

Was it perhaps because I knew she was smaller than my own body size that it intrigued me and caused a sense of wanting to protect her?

Moreover, if I looked closely, I could even see the bra line under her thin Y-shirt. I could also catch a glimpse of the deep cleavage formed by her chest.

Strange…

Even though I wanted to protect her, what was this contradictory feeling that seemed to have zero interest in protecting her…

“I’m going to take it off immediately… Or so I would like to say, but I’m not wearing any clothes underneath… So, can you go out for a bit?”

“Yes.”

I obediently complied with Neneka’s request and left the washroom. And then, specific thoughts surfaced in my mind. The other day, Neneka’s grandmother called me a “beast,” which had me surprised at that time, but now that I thought about it, every healthy high school boy had at least one “beast” sleeping deep inside their heart.

Yes, a mischievous, vicious beast that could go on a rampage if we made even a single mistake. However, we, high school boys had no intention of letting that beast go unchecked and wild.

I was trying to tame it so that it didn’t bother the people living around me. However, sometimes there were girls like Neneka who could quickly liberate these sleeping beasts, who then went wild instantly, so it was definitely a problem.

Then again, it was incredibly troublesome because all that would happen would be somewhat done unconsciously. Even now, the “beast” inside me was licking its lips and teeth with its tongue when I suddenly saw Neneka wearing my shirt.

While I waited for Neneka to change into her clothes, I took constant deep breaths making sure to keep my mind calm. Maintaining an animal was no easy task.

“You can come in now, I have changed into my clothes.”

I heard a voice and gently opened the door. Neneka was now wearing her T-shirt in the washroom.

“Umm… could it be that you came to help me?”

“Yeah… I thought it would be faster if we worked together.”

“Thank you. That helps a lot.”

Neneka took out the dried laundry from the washing machine, folded it, and put it in the basket. There were four baskets, each dedicated to me, Neneka, my mother and Neneka’s father’s clothes separately.

Standing next to Neneka, I also reached out for the clothes. I picked up my pajama pants and suddenly looked at Neneka. Looking at Neneka’s T-shirt felt weird.

–Why could I see the seams of her T-shirt?

Checking the back of the neck, sure enough, there was a tag hanging visible on the front side.

“Umm? Neneka… your T-shirt is probably worn inside out?”

“Huh!? No way!? Oh my… so embarrassing…”

Neneka’s face turned bright red when she realized that her T-shirt was worn on the seams-end. Probably while changing from my Y-shirt, she was in a hurry to put on her T-shirt and in that rush, didn’t notice that she wore her clothes on the opposite, seams-end.

“Mou… No more… I’ve been showing you my embarrassing sides ever since we started living together… Y-You ar-aren’t disillusioned, are you?”

Neneka’s eyes were watery. I could tell easily that she was worried about what to do if I started hating her. Although there’s no way that someone like me, who thought her every action was cute and adorable, would ever hate her.

“I’m not disillusioned at all. I’m happy to witness various sides of Neneka. If we hadn’t started living together as siblings, I probably wouldn’t ever have had the opportunity to see Neneka like this. I’m lucky…”

“Fufu… then that’s fine, I guess.”

Neneka smiled happily and threw her body at me. When I catched and pushed her, she again threw herself at me. While joking around for a while like that, I started feeling that Neneka was lovely and charming.

I embraced Neneka tightly as she again jumped onto me. Neneka’s shampoo’s smell emanating from her hair smelled good. I could clearly feel Neneka’s warm and soft body through her thin T-shirt.

“Daiki…”

Neneka embraced back tightly while calling my name.

“W-Wait! Neneka… W-What about the rules?”

“It’s not in front of our parents, so it’s not against the rules. So, please, just for a little bit longer…”

Neneka came yet closer.

–Oh no, this was bad… what should I do?

I didn’t think I would be able to let go of her anymore if it went on like this…

I was getting tempted. A little was starting to feel not enough.

Greed started assaulting me, wanting me to spend time forever like this…

“!?”

Suddenly right after, Neneka separated her body from mine.

“What happened?”

Before I could hear her reply, I noticed the current situation.

Footsteps…

Interactions…

My mother and Neneka’s father were approaching…!

Neneka and I instantly switched to sibling mode. I hurriedly took the laundry out from the washing machine and started folding them.

–Gacha.

“Neneka-chan. Are you done? You’ve already worked hard enough during the day, so let me help with the rest, okay?”

“Father will help too, so you don’t need to worry.”

While my mother opened the bathroom door. Neneka’s father appeared, peaking from behind. At that time, Neneka said sharply to me.

“Onii-chan! Fold the laundry more carefully!”

“I’m sorry!!”

“Ara-Ara Daiki… did Neneka-chan already find out that you’re sloppy?”

“It’s difficult, isn’t it? Folding out the laundry neatly. I’m always warned by Neneka too… So, umm… Neneka? Isn’t your T-shirt worn inside out?”

“Ah! This is, umm… it’s true! I also just noticed!”

“Really, Neneka is also quite sloppy as well…”

“Ahaha…”

In the end, everyone ended up folding their own laundry while arguing. It’s a pity that I got interrupted when I was enjoying my lover’s time with Neneka, but I didn’t feel that bad. This was also a fun and fulfilling time.

Still, I had to say, Neneka was so quick to switch and also good at acting in an instant. The two of us were doing our best to fold the laundry just a little while ago. It was really extraordinary to give out such an ambiance so readily.

–We were safe, thanks to Neneka.

It felt like we had crossed a dangerous bridge today, but somehow our relationship didn’t get exposed today either.
