Chapter 3

On the day my wife left me for cheating, two former students, high school girls, came to my house and were about to take a bath.

... Thinking calmly, what is this situation?

I guided the two of them to the shower room and gave a brief explanation of how to use it.

"Thanks, Okarin♡ Will you join us? Just kidding!"

The blonde gal, my sister Akari, smiled and showed a glimpse of her shirt's chest.

By the way, they are half, so Akari's hair color is natural.

"... Stop joking and get in already. I'll prepare your clothes."

I've known them since I worked part-time at a cram school.

In other words, I know them well from their childhood.

To me, it feels like I'm meeting my relatives' children after a long time.

"Che. Okarin is so boring. You should make my heart race more★"

"I'll bring your clothes later, so go in first."

I left the changing room.

... But why did my sister Nanako cry just now?

I said it was to make her feel at ease...

"Ah... I see. You were with me."

The old memories were just as I remembered... I felt relieved.

... But, if she cried, it might mean she went through something painful, just like me.

It's been 10 years since we last met.

But I don't know what happened to them in those 10 years.

However... two high school girls asking to stay at a man they barely know's house.

This... is an abnormal situation.

"... Something must have happened to those girls."

I headed to the bedroom to prepare their clothes.

The unpleasant aftermath of my wife and her lover was still there, which was unpleasant.

I threw the clothes and condoms into the burnable trash.

The futon... I'll think about it later. I folded it and put it on the balcony for now.

I borrowed Misae's clothes and took a towel, then returned to the changing room.

"Wh...?"

"Wha!?"

... There, just out of the bath, were Akari and Nanako.

"Ah...♡"

The first to turn red and crouch down was Akari.

"Akari, stand up!"

On the other hand, Nanako picked up her sister and took her back to the bathroom.

"Se... sensei... I'm sorry!"

Nanako's voice came from the other side of the bathroom.

"No, I'm the one who should apologize..."

"It's... It's fine. Akari doesn't seem to mind either."

... I shouldn't have done that.

I should have knocked.

But... people change over 10 years.

Because their personalities were the same as before, I treated them like they were still elementary school students.

However, they are now full-grown adults in both body and age.

I need to be careful and maintain propriety.

"I'm sorry. I'll be more careful next time."

I said this to them through the door.

"... Don't worry about it. It was an accident."

"Uu... Okarin's... pervert."

★

After a while.

I lent my sweats to Nanako and the others who came out of the bath.

For underwear... I thought of using Misae's, but they said it was too tight.

"Uncle, we're in a bind. We're not wearing any bras or panties... Kyaa♡ We might be attacked!"

Akari acted as if nothing had happened in the bathroom just now, but her ears were still red.

She must have been embarrassed and was trying to act tough.

"... Stop joking and sit down. I'm doing the laundry now."

"Hehe. Sorry."

Nanako and the others, fresh out of the bath, looked even more alluring.

I couldn't help but look at the bulge in the sweats, but they are still children.

I shouldn't look at them that way.

"Okarin... Are you castrated or something?"

"Huh?"

"... Akari, that's not appropriate!"

Nanako restrained Akari from behind.

"Ugh... But, a high school girl just came out of the bath! And she's not wearing a bra! Wouldn't you... get excited?"

"Stop it, you idiot!"

"Moreover, look at her chest. Without a bra, it doesn't lose its shape at all. It's terrifying."

"Stop it. I wouldn't get excited over a child."

"Che... Che..."

... Why are both Akari and Nanako disappointed?

"By the way, Okarin, the washing machine doesn't seem to be working?"

"Eh!? ... Really?"

I hurried to the changing room.

It was making a strange beeping sound and wouldn't start.

Even after unplugging and plugging it back in, it wouldn't work.

"Oops, it's broken?"

"... I'm sorry, it seems so."

"Hmm. This is a problem..."

Akari smiled.

"Without clothes to wear, we can't go home. And the repairman won't come at this hour..."

... This girl.

But she's right.

"... Akari, I'm sorry. I'll use the coin laundry nearby."

"Aaah! You should have kept quiet! Now I thought we could stay over!"

... Akari seemed to have realized.

Come to think of it...

"But, but, is it okay for you, Uncle? Taking high school girls' clothes to the coin laundry might make people suspicious..."

"Alright, you can stay."

"Wh...?"

Akari and Nanako both widened their eyes.

"So, you can stay."

"R-Really!?"

"Yes... But only for today."

The two of them looked at each other, beamed, and hugged each other.

"Yay! Yay! Good job, Nanako!"

"... Yeah, it's good."

... Honestly, I have no idea what's going on.

Why these two came to me...

What their parents are doing... I don't know.

But... one thing is certain.

... Since meeting Nanako and the others at the doorstep until now.

I had forgotten that my wife cheated on me and that my junior stole my wife.

"Then, Uncle, I'll make dinner for you~"

"Can you cook?"

"Of course! But, unfortunately, I'm a terrible cook."

"... Akari, that's unnecessary."

"So, I'll make it up with my body~♡ Just kidding~♡"

"..."

"Eh, it's a joke, Nanako. Why are you blushing? Hmm~?"

... In the end, I ended up letting the two high school girls stay that day.

But I never imagined that from that day on, I would be living with the two of them...

I never would have thought.
