Parents remarried. Now my lover starts referring to me as "Onii~chan" - Chapter 3 Part 1

Chapter 3

Yesterday, Neneka’s father laughed, saying, “You both get along like real siblings.”

We must be good children and thoughtful of our parents.

They probably thought of us as ideal children who quietly accepted their new life after their parents’ re-marriage.

–I was sure that not even in their wildest dreams had they thought that their two kids were actually dating and flirting in their shadows, behind their line of sight.

Today was Saturday.

My mother and Neneka’s father had to go to work.

My mother was a nurse at the university hospital, so she often got shifts on Saturdays.

Neneka’s father worked for an IT company and basically had his days-off on weekends and holidays. However, sometimes he was called to work on weekends.

Therefore, right now, there was only Neneka and I at home.

In other words… today, there would be no one to get in the way as I flirt with Neneka.

–Perhaps today I could at last kiss Neneka…?

As I expected that, my heart started pounding on that thought. Our parents would probably return around the evening. Although it was earlier than usual, it was more than enough time to spend alone with Neneka.

In the meantime, we didn’t have to pretend to be siblings. I could treat Neneka as my girlfriend, and Neneka could also treat me as her boyfriend.

After a week had passed since we started living together. At last, it was finally our bonus lover’s time.

“Neneka… About today, do you…”

I went to the living room in order to discuss how we should spend our time together. But, Neneka was back in the kitchen.

“Eh? What are you doing there?”

I asked Neneka, who was busy cooking in the kitchen.

“Fufu… I’m cooking.”

Neneka replied while wearing a floral apron.

She had prepared many ingredients and was already finished with some dishes, consecutively putting them in storage containers.

It was to the level that someone might even think it was for some night party.

“What will you do with such a large amount of food?”

“I will keep them refrigerated or frozen. If I make a batch of them this weekend, then all that would be left to do would be to microwave it on weekdays, and we could have something to eat right? It would save time and money, and all in all, it’s convenient.”

Near Neneka, there was a book titled, “The strongest pre-made recipe collection.”

When I flipped it open, my fingertips touched a sticky note that I thought Neneka had put on it.

–What should I do… My stepsister was just too good of a person…

Even after the re-marriage, our parents were still working, and it became us, children’s responsibility to prepare weekly meals. The custom was to be continued without a change even after the re-marriage.

But now that I had a sibling, I didn’t have to do things I had been doing all alone. With such a sense of security, I felt really relaxed, however…

“After living with Daiki’s family, I was at last able to learn something over this past week. It’s that I could enjoy cooking together with Daiki. Still, it’s indeed difficult to cook for four people right after returning from school and buying ingredients for the food… Daiki? What’s wrong?”

Neneka, who was putting several containers in the freezer, saw me speechlessly standing in awe.

“No… I just thought Neneka would become an excellent wife in the future…”

“Huh? E-Eh, wife?”

Suddenly, Neneka’s cheeks turned red.

“D-Do you think I-I can be a good wife…?”

Neneka asking that timidly looked just incredibly cute.

“You can definitely be!”

“Really? Does… Daiki also feel like it would be good if I became a wife in the future?”

Seeing Neneka’s embarrassed expression, my stove made a ticking sound.

Hey, hey, don’t light up with just this, my stove!

“… I do think so.”

I told Neneka calmly so that she wouldn’t feel anything suspicious.

“Really? I’m so glad…”

Neneka’s shy smile looked just too adorable. Neneka happily, smiling, peeled off the skin of the carrots one by one. For some reason or another, I averted my eyes from the peeled carrots and looked out the window.

Ah… What a clear sky!

While looking at this refreshing blue sky, I went on to purify, my evil, lustful thoughts.

Today, our parents were not at home with us, so it might not be a problem even if my stove ignited with its flame in full strength.

However, I didn’t want to disturb Neneka, who was doing her best to cook for our family.

“Can I also help in one way or another…”

Neneka immediately reacted when I whispered.

“Ah, then, can you take care of washing the laundry with the machine? I still don’t know to to use the washing machine at Daiki’s house…”

“Roger that…”

Wanting to show some of my good sides, I briskly headed to the washroom. A thick pile of clothes was accumulated when I looked at the laundry basket.

–As expected from a family of four, the laundry did pile up rather quickly…

We had a front-loading washing machine with a dryer.

It might have been too sophisticated to wash clothes in it in a household containing only a mother and her son.

However, its size was just about right for washing a large amount of laundry for four at once.

Having a dryer was very convenient. Put things in the laundry basket into the laundry net appropriately, then throw them into the washing machine.

My mother taught me how to use a laundry net, but to be honest, I didn’t really know what to put in it.

Almost everything was done, not overthinking about it.

Then, my hand somehow touched something resembling a beautiful lace.

–I should probably put the lace-type materials in the net.

Even I knew that much. When I pulled out the lace material with a triumphant look, what appeared there was a pink brassiere.

“…”

I was a healthy high school boy who grew up in a single-mother household. Thanks to the daily housework, I instantly knew that this bra was clearly bigger than my mother’s bra.

–It was Neneka’s!!

I just couldn’t take my eyes off it.

–No… Before I think of something unwarranted, I should take my hand off that bra!

Don’t try to synthesize my imaginations of this bra with Neneka’s naked body that I saw on the first day of living together.

“Daiki?”

–“…!?”

I was so surprised that I forgot how to breathe. Neneka’s voice came from behind.

When I fearfully turned around, Neneka was standing at the entrance of the washroom.

She was staring at me with her eyebrows curled up.

“I came to ask where the olive oil is…”

Neneka’s eyes staring at me must have already caught the existence of her bra being ravaged by my hands.

My blood suddenly felt drained, and a cold sweat flowed down.

“No… umm… this is…”

“Hey… Daiki! That thing, isn’t that supposed to be a bad thing to do…?”

She would get angry. No, that might not even be it at all.

–She might get disillusioned.

As I prepared myself, Neneka continued.

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

“Eh?”
