Volume 3 - CH 1.4

Long before the beginning of the common era, there existed a prehistoric civilization. The romance of ancient civilizations with advanced technology surpassing the present day is endless, but for us living in the present, knowing the history after the start of the era and the year 1 AD is challenging enough.

While indulging in the grand history and letting our thoughts wander, there is something important we must not forget. Let’s reflect upon the humble and trivial history.

Within the nine-square-meter room, there exist two distinct eras: the ‘Old Era of My Room’ and the ‘New Era of My Room.’ The transformation was truly dramatic.

My modest and lifeless room has completely changed, adorned with pastel colors spreading throughout.

The prehistoric civilization has vanished without a trace. Even finding remnants has become a challenge.

And suddenly, a dresser appeared. It wasn’t there just yesterday!

Of course, it is evident that the culprit behind this change is either my mother or sister, or perhaps both. Despite me meekly protesting their casual intrusion into my room, they pay no attention. Dependent family members can be tough to handle.

As I silently weep in my heart, studying in this restless room, an unprecedented crisis suddenly befalls me. It is a predicament comparable to forgetting the function calculator essential for my qualification exam. This is the Great King Angolmois that Nostradamus prophesied.

Trembling with powerlessness in the face of an approaching adversary, I find myself backed against the wall. There’s no more room to retreat. Determined to face the overwhelmingly powerful opponent, I muster up the courage to confront them.

“Regain your sanity, sister!”

“I am always sane.”

Attempting to persuade her, I realize that my sister is indeed sane. If that’s the case, then this is it!

“Don’t regain your sanity, sister!”

“Yes, maybe I have lost my sanity a long time ago.”

“Invincible, huh?”

I am completely defeated by Yuri-san, who flawlessly defeats my strongest and invincible theory. I can’t even look directly at Yuri-san. However, a divine inspiration descends upon me, and a solution comes to mind.

“I’ve got it! Just wait a moment!”

I rush out of my room in a panic, heading to retrieve what I need.

“Fuufuufuu. This will make it perfect. I’m ready now. What do you need?”

I accidentally stub my toe against a corner, causing excruciating pain.

“Gyaaaaaaaaaaaaaaaaaa”

“What are you doing!? Are you okay? It’s dangerous to do something like that.”

With a flick, the eye mask was thrown away. My eyes were also badly damaged.

“Why are you naked?!”

“Didn’t I ask you to measure because my chest had gotten bigger? I need to buy new bras too.”

“So, you weren’t joking…”

Come to think of it, I vaguely remember her mentioning that her underwear had become tight.

“Wait, am I really the one who’s supposed to measure?”

“Ha? Who else would do it if not you?”

“What about Mom?”

Actually, isn’t anyone other than Mom more suitable? It seems like a more appropriate task for someone other than me.

“Mom is my rival. She may be ahead of me for now, but eventually, I’ll surpass her.”

“I see…”

Since I didn’t quite understand, I gave a vague response.

“You’re already used to seeing me naked, right? Why would you be embarrassed just to measure my bust size?”

“I don’t think it’s good if I’m used to seeing it.”

“?”

My sister tilts her head in confusion.

“Was there any reason to doubt that?”

I tilted my head in confusion as well.

“You don’t have to worry about that. Let’s get it measured. Bring the measuring tape.”

My sister clasps her hands behind her head and opens her armpits wide.

As a teenager, it was a seductive and toxic sight for me to behold, but she seemed completely unfazed.

There it was, a perfect masterpiece. Her beautiful posture resembled that of a sculpture, evoking a divine presence. Flawless and delicate skin devoid of any impurities. Its purity, Twelve Nine.

I dropped to my knees. Thunderous applause resounded in my heart. I savored this overwhelming sensation.

A meeting of the modern Renaissance. Driven by a yearning that welled up from the depths of my heart, my voice trembled.

“…Erotic Venus.”

“It’s by Milo.”

My mouth slipped! Slipped! Slipped! (Echo)

“If you say so, then it’s fine.”

“It’s okay.”

I could only admire her incredible tolerance.

“You measure from the back. The difference between the top and under determines the size.”

I acquired unnecessary knowledge again. Sister harassment is on the verge of exploding tonight.

If I don’t measure, it seems like this won’t end. Gathering my courage, I slowly wrap the measuring tape from the back. Aligning it to intersect at the top and adjusting the numbers… Ahhhhhh!

“Mmm… It tickles…”

I need to escape from this hell as soon as possible, or my credits will run out, and my life will be unable to continue.

“..There….rub there…!”

I haven’t heard anything, I haven’t heard anything, I haven’t heard anything, I haven’t heard anything. What number repetition is this now?

“Subtraction, yes, I need to subtract! Uhm… Around twenty-five centimeters, maybe?”

I check the size chart with a crawling body. I should look at the column for a G cup.

It’s only now that I realize there are different types even within the same cup size. Being a woman is tough, unlike men. It’s quite educational since I’m learning sewing.

“It seems like I’ve grown after all. Measure me once a week from now on.”

“Isn’t that too often!?”

“It’s the growth period.”

“The growth period is incredible.”

The persuasiveness of the growth period is unmatched.

Anyway, even though the measurement is over, my sister, who usually doesn’t care, continues to stare straight at me.

“What’s wrong? It’s not something that will decrease, so feel free to look.”

“Have a little more modesty…”

“We’re family. You don’t need to worry about that.”

“Well, if you feel that way, I have something to say too!”

Snap. Finally, I snapped too. Even my patience has its limits. Despite having a mental fortitude as unwavering as a level, there are limits, just like the credit limit on a credit card.

There’s a saying about familiarity breeding contempt, but even within a family, there should be some manners.

Cut it out already. What’s with that attitude when I’m the one putting up with it!

Yeah, I understand. Fine! You started this war. I’ll take you to the limit!

“Jii.” (Sfx stare)

I stare intently. I gaze freely. It’s like an eye examination. I let my gaze roam all over her body.

Fuhehehe. How’s that? Isn’t it intimidating? Experience the power of a lewd and lascivious gaze filled with hidden motives!

Yuri-san flinches for a moment. I won! Along with a sense of accomplishment comes a sense of loss.

The cost of victory is high. I’m disqualified as a little brother, and there’s no way to justify my actions even if she looks at me with disgust.

As I inwardly panic, she embraces me gently.

“Yes, that’s enough. Do as you please. I’ll accept everything. Because… I only have that… My worth… My purpose… Be true to your feelings and prioritize emotions. If it’s what you, Yukito, desire, then I’ll do anything…”

Suddenly, Yuri-san snaps back to reality and moves away.

“It’s nothing.”

“Sister?”

For just a moment, her eyes flicker with a touch of sadness.

Feeling an indescribable uneasiness, my gaze wanders. What was that just now…?

Starting over, Yuri-san opens her mouth.

“I’m going to buy underwear, so you’re coming with me.”

“I decline.”

“I’ll buy you underwear that you like.”

“Even if you say it in such a flippant way like buying me candy, ……

“Ha? You are coming right?”

“Please let me join you.”

Our outing is decided. Maybe we’re gradually returning to being a normal brother and sister.

However, the bittersweet and troubled expression on Yuri-san’s face remains etched in my mind.
