Parents remarried. Now my lover starts referring to me as "Onii~chan" - Chapter 3 Part 2

“Since it’s your younger sister’s underwear, shouldn’t you just wash it right away…?”

“Eh?”

She wasn’t offended…?

Seeing that unexpected reaction from Neneka. I was taken aback.

Neneka calmly approached me and said.

“Since we’re now living together. I’m sure there will be many more opportunities to see them from now on. If you overreact like that each time… Our mother will get suspicious of you and think that you’re probably looking at me as a member of the opposite sex, right? Therefore, rule addition. Rule 8! My underwear should be splendidly ignored!”

“I-Is that so… Then I should just think of it as just a piece of cloth and ignore it…?”

I tried to gently move Neneka’s bra, which I had been holding in my hand for a while, into the washing machine. Still, for some reason, Neneka grabbed onto my hand and stopped me immediately.

“Wait!! I won’t ask you to wash it with your hands, so at least put it in a net first!!”

“I-I understand…!”

I hurriedly put it in the net and threw it in the washing machine. I knew that I should put things made of lace into the net until just a little while ago, but I was so flustered that I just forgot about it.

Dangerous, dangerous…

As I calmed my pounding heart, Neneka said, staring at the washing machine.

“Hey, Daiki. This washing machine has a dryer, right? So, can you take out the clothes that you just put before you put it in the dryer? I heard that if you put them in a dryer, they get damaged faster.”

“Ah, after it’s finished washing, I’ll only take out the clothes that shouldn’t be dried by it. At that time, I will also take out my mother’s… So well…”

“I see… Daiki is really upright. Ah, it is not like I noticed it just now though.”

Neneka was fidgeting.

After all, it might have been embarrassing for her to have her own underwear touched.

“… I’m sorry to have touched your underwear… without permission. Should I try not to touch it from now on?”

“Uh… huh! It’s okay! But basically I will try and put my underwear in the net and put it in the washing machine by myself. Even so, there might be chances when you encounter it… So, I will think of it as, since Daiki is my Onii-chan, it can’t be helped if it’s seen, so I will ignore it!”

“I understand.”

“Ah, more importantly, where is the olive oil…?”

“Ah, umm, it must be in the storage shelf under the stove.”

“Thank you. I’ll look for it.”

When Neneka left the washroom, I breathed a sigh of relief. When I was alone, my eyes naturally turned to Neneka’s bra.

Her bra was now wrapped in the laundry net and was almost invisible. Thinking that it was my younger sister’s bra, I decided to let go of it.

However, there was one thing that really bothered me.

–I wanted to see the size…!

This couldn’t be helped! Even brothers got curious about their younger sister’s size…!!

Since the time I saw her naked, I was curious about it. What was her chest size in terms of cups?

I gently reached for the laundry net that was just put in the washing machine.

Over the net was fine. I wanted to see the size…

When I picked up the laundry net without opening it and was just about to find the size written down on the tag…

–“Onii-chan…?”

My body suddenly had a lightning bolt run through it.

“Ne-Neneka…?”

When I turned around, I saw my stepsister smiling gently. No, her eyes were not smiling.

“What are you doing?”

“Ah… umm… I was wondering if the net zipper was properly closed…”

“I see… that’s fine, but… it’s embarrassing if you stare at it that much, so I would like you to stop looking at ITS details…”

“I’m sorry! It was just a sudden impulse!”

I felt disqualified as a brother.

I dropped my shoulders to my actions and my pathetic figure who gave in to temptation.

After that, it was already evening while busy cooking, washing, cleaning and tidying up.

The four of us had just moved in together a week ago, and there were things scattered around the house that we couldn’t find a place to put them.

So, Neneka and I worked diligently to make things tidy. That included tidying up the washroom and the shoeboxes so that everyone could use them easily.

While talking with Neneka and devising various things, it became so much fun that I lost track of time.

Our family was no longer just “us and our single-parent.”

After our parents went off to work, we no longer had to be all alone at home.

I thought that was probably what made Neneka and I both happy and excited.

And before I knew it, I had forgotten that today was the day I had planned to kiss Neneka.

Later today, at four o’clock in the afternoon, our parents came home together. It seemed that my mother, who had finished her work earlier went all the way to pick up Neneka’s father from his office by car and brought him home rather than having him take the train to come home.

After that, we all ate the dinner that Neneka and I had prepared.

Later on, I took a bath, and Neneka took one afterwards…

With that, now I was fooling around in my room.

I felt that Neneka would come to my room today for some reason, so I waited for her to get out of the bath.

But even after more than an hour had passed, there was no sign of Neneka coming upstairs, let alone coming back to her room.

“I wonder what’s taking Neneka so long…?”

Curious, I headed downstairs. I looked into the living room, but only my parents were there.

Where was Neneka?

“Daiki? What happened?”

My mother noticed my presence, called out to me while sitting beside Neneka’s father. At that time, I saw the two sitting side by side on the sofa, holding hands and watching TV. Really, they were such close newlyweds.

“Do you know where Neneka is?”

My mother pointed at the upper floor with her free hand when I asked.

“Isn’t she in her room upstairs?”

“I felt like she wasn’t there, though.”

“Ah, then maybe she is still busy folding out the laundry. I just asked her to help me do it, but she told me to take it easy since I had just returned from work. Neneka-chan is really a very sweet and kind girl.”

“I see…”

Neneka who continuously worried about our parents, was definitely the image of an adult. If I was alone, I would have done the housework during the day and probably would have asked my mother to take care of the rest at night.

–I wondered if I should go and help her…

When I saw my parents getting along well and flirting, I also felt the urge to flirt with Neneka. As a reward for my hard work during the day, I wanted to spend some sweet time and ambiance with Neneka.

She would probably be in the washroom if asked to fold the laundry.

Without hesitation, I headed to the washroom where I could see the lights turned on through the small window glass above the door. I was sure that she was indeed inside.

I opened the door without knocking.

–Gacha.

“…”

“…”

Neneka and I just stared at each other without uttering a single word. Neneka was wearing my school Y-shirt while she was in the washroom for some reason or another.

She seemed to be wearing shorts too, which was her room wear. But since she was almost entirely covered till the hem by my Y-shirt, I got perplexed, thinking that she might not have worn anything underneath for a moment.

Well even if I had known that she was wearing something right underneath, other factors made my blood rush in excitement.
