We look at each other as adults in the place where we used to live.

Sera, who had always teased and annoyed me, was now standing in front of me as an adult, smelling of something that tickled my manly instincts.

I quickly tried to remove my hand from Sera’s stomach, but she used her free hand to press my hand further down on her stomach. Every time my hand brushes against Sera’s navel, I feel an indescribable feeling growing inside me.

“N-No …… I’m not running away. You see, I’m working for Reganda and I’m doing fine.”
“I’m not talking about running away.”
“Then what do you mean?”

Sera gave me a devilish look of confusion. But there was a sexiness in her face that I had not seen in her in the past.

“You know what I’m talking about.”

Despite being two years younger than me, her bewitching face and body make such a strong impression on me that it makes my body and mind clench.

How should I know…..

“Even as an adult, no matter what you do, Yuuni-chan is still Yuuni-chan. That’s why I understand. Yuuni-chan, you’ve been holding back all this time, right?”
“Yuuni-chan will always be with us. Even if Yuuni-chan pours all the emotions you have inside your heart into my body and mind, we’ll always be together …… forever.”

Oh no.

When she said something like that while feeling Sera’s belly. ……

“Sera chan”
“I’ve always wanted you guys to be happy. But I don’t know what will happen if I tell you how I feel. Because this relationship itself might disappear. ……”

Sera comes up to me at close range, breathes sweetly, and whispers to me.

“If Yuu niichan isn’t happy, we won’t be happy either. So please tell us your true feelings.”
“True feelings ……”
“Yes. Real feelings. I want to hear it from your mouth.”

My true feelings.

Thoughts I’ve been hiding for a long time.

The things that are not the way.

I open my mouth to Sera’s emerald eyes, which keep sending me a gaze that seems to suck me in.

“Sera chan is right, if we die, the precious memories will be lost. So I thought. Why don’t we create a whole bunch of entities to prove the bond we’ve built?”
“Proof …”

Sera put her hand on her chin with a reluctant expression and thought for a moment. Then, she smiled and looked me in the eye, as if she had an idea.

“So you were worried.”
“Yuu niichan.”
“Let me tell you something.”

Sera blew her breath gently on my ear.

“That’s what we’ve been thinking, too. We’ve been thinking about it ever since we got separated.”

W-What is i!?

“We don’t have to put up with anything anymore. Let’s make a lot of existence that proves our bond from now on.”

Sera’s words numbed me as if I were running on electricity, and I was helpless to do anything about it.

“Sera-chan …… I …… I!”
“Fufu, Yuu ni-chan!”
“I can’t take it anymore!”

“Come here.”

We moved to Sera’s car.


“It’s night already, isn’t it?”
“I’m sorry. I thought I should be nicer to you since it’s your first time. ……”
“No, don’t worry about it. But the car is pretty dirty, so it might be hard to clean it.”
“I’ll help you.”
“Thank you.”

Leaving the car window open we’re heading back the way we came. But since it is completely nighttime, we are not heading to Reganda, but to the luxury tower apartment where the three Kirie sisters live.

It takes about an hour from here to the tower apartment. From a child’s point of view, it must seem like a daunting distance.

However, after coming here in person, I realized that this is a place where I can go as much as I want if I want to.

In other words, it is a space that is within reach.

If that is the case, then from the beginning, the girls and I have been thinking about ……

As I was driving and thinking about various things, I could see my lovely Sera sleeping peacefully next to me.

My cheeks relax and I take advantage of the time I’m stuck at a red light to gently stroke her soft head.

It’s mine.

Sera’s beautiful body and heart.

Not only Sera.

Ai nee and Arisa are all mine.

If my happiness is connected to theirs.

I will pour all my black heart into them.

I will pour it into their hearts and bodies.

My eyes in the rearview mirror

I’ve already lost the color of my eyes.

This may be my true form.


“Yu ni-chan, thank you so much for today.”
“Thank you, too, for accepting my feelings.”
“Sera chan? What’s wrong?”
“You’re going home huh”

Sera glanced at me as we stood in the underground parking lot of the tower apartment building. A lot had happened today, and I wanted to go back to my place to rest, but apparently Sera did not want to do that.

If that was the case.

I don’t think I need to be afraid of her.

“Sera chan”
“Can I borrow your car for a minute?”
“I’ll stop by my house. I have stuff to bring.”
“!!! Yuu niichan……”
“What’s going on?”
“I’ll help you. You’re my Yuu nichan.”

Sera did not go back to her own house, but headed to mine. And from there, I put my clothes, laptop, and other things I usually use (except pornographic books) in the car and moved again to the tower apartment where the three Kirie sisters were.

I had been to the parking lot a few times, but this was the first time I had been to the house itself.

Sera opens the front door with excitement.

“I’m home”

Sera announces her return in a silly voice.

“It’s bigger than I thought it would be.”
“I know, right? Yuu niichan’s room is huge too! Let’s sleep together tonight.”
“Hahaha….. that’s…”
“What’s with that reaction? It’s totally different from when we were in the car.”
“W-Well, that’s ……”

As Sera and I were exchanging conversation, suddenly two people came running from the living room at a breakneck speed.

“Good evening. Both of you.”
“That suitcase ……, Yu-chan?”
“Are you going to live here?”
“W-well, …… there’s still a lot of luggage and stuff, so it’s going to be a bit difficult.”

Ai nee and Arisa, dressed in their normal clothes, rolled their eyes and shook their bodies.

Then Sera poked me in the side with her elbow.

“Yuu-niichan, tell my sisters how you really feel, and quickly!”
“! Y-You’re saying that here and now?”
“Because you don’t have to hide it anymore. In addition, my sisters know all about it. But if you don’t tell us in your own words, it won’t mean anything.”

Ai nee and Arisa look at me expectantly.

I let out a short breath and convey my true feelings that have been building up over the past 15 years.

“I …… have been lonely. Ever since we got separated, I’ve been stifling my emotions. I’ve managed to get by by pretending on the surface that things are going well, but there was no one to fill my heart. After my father died, it was even more difficult for me. …… Then I met Ai nee, Arisa, and Sera chan, and I realized that they were the only three people who could fill my heart. Then I realized that the three of them are the only ones who can fill my heart. ……15 years have passed and it’s still the same. Or rather, I think the long time that has passed has made this feeling stronger.”

Ai nee and Arisa look at me tenderly, their eyes moist and the corners of their mouths slightly lifted.

“But like our mothers and fathers, we will eventually die. So I’ve thought a lot about how to make sure this bond doesn’t disappear.”

I cut them off and caught my breath.

Then, I said something off the cuff to the three of them.

“I want the three of you to have a child with me. Then, when we die, our bond will remain.”

When the three sisters heard what I had to say, their bodies twitched for a moment.

For a moment, such fears that they might harbor feelings of contempt, disregard, dislike, or hatred toward me flashed through my mind, but I could not hide these burning hot feelings.

Biting her lip, Sera turned over and moved to Ai nee and Arisa. The three sisters then called my name without expression.

“Yuu chan”
“Yuu nichan”

Of course I am anxious, but more than that, the bond we have spun together reassures me.

I will not run away again.

I cannot run away.


I know the hearts of the three sisters.

“”Let’s have lots of babies. darling.””
“Yeah. Let’s have lots of babies.”

“”Welcome home.”
“I’m home.”

I take off my shoes and walk over to the three sisters.

From a distance, I look like a prey approaching an insectivorous plant with plenty of nectar.

That’s how much my body and heart fell in love with the three Kirie sisters.
