If an Unrelated Sister and Brother Are Both in Love With Each Other, Isn’t It Just a Matter of Time Before They Get Together?

Chapter 17: And Then, the Worst Result

“Hmm, hmm ♪ Kya! What, what?”

“Hehe…”

While Kinoka-neechan is happily humming and getting ready to clean, I squeeze her chest from behind again.

This is already a daily occurrence, and I can do whatever I want with Kinoka-neechan’s body, and I feel like a king.

After all, I can do whatever I want with such a beautiful older sister.

I don’t care if she’s pretending to hate it.

She’s mine. Now that I’ve decided that, I have no worries.

“Hey, show me your boobs.”

“Huh? No way.”

“Why not? We’ve done it many times…”

“That’s different! I’m cleaning now, so don’t disturb me.”

I persistently squeeze Kinoka-neechan’s chest from behind, and I also touch her butt and thighs.

I mean, she’s wearing hot pants that expose her thighs, and her tank top exposes a lot of her upper body.

I can’t help but think she’s inviting me.

“Why aren’t you sleeping naked lately?”

“Because I get cold when I turn on the air conditioner. I told you I don’t do that often.”

“From now on, you have to sleep naked. I find it easier to rape you that way.”

“That’s why I stopped! Come on, don’t disturb me…”

I get a little annoyed because she doesn’t listen to my whims, and I push Kinoka-neechan down right there.

Hehe, summer vacation is coming soon… I’m going to have a lot of fun from now on.

“Hey, stop it…”

I’m really horny during the day… well, it’s okay.

I don’t think Kinoka-neechan really hates it, and she’s accepting me because she likes me.

“Good morning… um, Kinoka-neechan, you’re still not going to work?”

Summer vacation has started, and I was sleeping a little late, but it’s the time she usually goes to work, and she’s still at home.

“I’m going to the doctor. I used my vacation days at work, so it’s okay.”

“Huh? Are you feeling sick?”

“Yeah. I don’t think it’s a big deal, but I’m going to get it checked out. I’m going now.”

“Oh, okay.”

I’m very curious, but Kinoka-neechan gets ready quickly and leaves me to go to the doctor.

Is she sick… but she doesn’t look pale, and I don’t see anything wrong with her, but I’m worried.

Kinoka-neechan is usually very healthy and rarely gets sick, so I was worried, but I could only pray that it wasn’t serious.

“Hmm, I’m bored.”

I’m bored because there’s nothing to do without Kinoka-neechan.

It’s too hot to go outside… I mean, I have to look for a part-time job, but I haven’t decided anything yet, and summer vacation has started.

Well, Kinoka-neechan has summer vacation, too, so I’m going to have a lot of fun with her.

“I’m home.”

“Oh, welcome back. You were late.”

Kinoka-neechan finally comes home in the afternoon, and I greet her.

“How was it?”

“Yeah. Come here.”

“Huh? Yeah.”

I try to ask about her condition, but Kinoka-neechan pulls my arm and takes me to the living room.

What’s going on? She looks serious, but does she have a strange disease?

“What?”

“One month.”

“Huh?”

I tilt my head, not understanding what she means, and Kinoka-neechan suddenly tells me in a serious tone,

“I was pregnant. For one month now. With Haru-kun’s child.”

“…”

I’m stunned by the sudden announcement.

What do you mean, “pregnant”?

“Um… seriously?”

“Yeah. I haven’t done that with anyone but Haru-kun, and you’re not a kid anymore, so you know, right? If you do that, this might happen.”

Kinoka-neechan says that to me in a cold tone, and I can’t keep up with her, and I can’t find the words.

“You decide.”

“Huh?”

“I’m your thing, right? So, I’ll obey you completely, so decide whether I’d give birth or have an abortion.”

I’m stunned, and Kinoka-neechan continues to press me in a calm tone.

Do I have to decide? I mean, I should be happy, but I’m not…

“Hehe… it’s a joke…”

“I don’t say things like that. Here, this is the medical examination card from the hospital I just went to. I went to an obstetrics and gynecology clinic.”

Kinoka-neechan hands me the obstetrics and gynecology clinic’s medical examination card without giving me time to think it’s a joke.

“What does Kinoka-neechan want to do?”

“I told you I’ll obey you completely. I’ll leave it up to you whether to give birth or have an abortion. If I say I want to give birth, you’ll have a hard time telling me to have an abortion, right?”

Kinoka-neechan insists that I decide, and she starts changing.

She tells me in a cold, dismissive tone that I can’t imagine from the usually kind Kinoka-neechan, but I’m still in a daze.

“You have to decide as soon as possible. You can only have an abortion up to twenty-one weeks of pregnancy. So, it’s about four months. You have to decide before then, or you won’t be able to have an abortion, so keep that in mind.”

“Um… what?”

“What’s up?”

“Are… you angry?”

I grab Kinoka-neechan’s arm and ask her that, and Kinoka-neechan sighs in exasperation.

“I’m not angry. But I’m your thing, and I think this is fate, so I’ll accept it, and I’ll leave it up to you whether to give birth or have an abortion. Right? I’m your thing, right? So, you have to take responsibility.”

I hear Kinoka-neechan’s mechanical words, and I collapse where I stand.

I mean, I couldn’t have predicted this would happen.

But I took advantage of her because she didn’t resist and didn’t get angry, and the result of that is… this.

(It’s my fault for getting carried away…)

I feel like I’ve been thrown into hell just as I was feeling like she was mine, and I couldn’t leave the house for a while.
