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 15: Even if I Sneak into Her Room at Night, the Initiative is...

Chapter 15: Even if I Sneak into Her Room at Night, the Initiative is…

“One, two…”

“Huh? What are you doing, Haru-kun?”

The next night, after returning from school, I do muscle training like push-ups and sit-ups, and Kinoka-neesan looks at me with a puzzled expression.

“What do you mean? I’m working out.”

“Hmm. Why?”

“It’s… to keep up with Kinoka-neesan.”

“Huh? Me?”

Kinoka-neesan is also surprised, but I mean what I say.

I’m working out to overpower Kinoka-neesan with force.

I’m training myself to be able to rape her even if she resists.

Not to protect, but to defile my most beloved—

(Uoooo… I’m the worst brother and boyfriend.)

I feel self-loathing and an unusual excitement at the same time for being such a scumbag, worse than any abusive boyfriend.

Why did I become such a terrible man?

Yesterday, I crossed the line and raped her, but Kinoka-neesan acts as if nothing happened, and she continued to treat me normally.

Last night, there was a slightly awkward atmosphere, but in the morning, everything was back to normal.

She even gave me a kiss goodbye without being asked.

I think she likes me so much. But I don’t know if she sees me as a man.

I’m very frustrated that she treats me so normally, and I even feel like she’s teasing me, which might be why I’m annoyed.

“I don’t know what you mean, but I’ll work out at the gym, too, so I won’t lose to you. Something about Haru-kun lately is scary.”

“Is it that scary?”

“Of course, you suddenly did that to me yesterday.”

“Hmm. Are you angry?”

“I’m angry~~~. You took my virginity like that. Are you sorry?”

“I’m not.”

“You say that so clearly…”

If she were really angry, she wouldn’t be able to say so lightly that her brother-in-law raped her, but I think she’s teasing me.

I need to punish her more.

“Huh. So you don’t like this kind of thing.”

“Huh? Kyaa!”

I stop doing push-ups, get up, and squeeze Kinoka-neesan’s chest from behind, and as expected, she screams.

“Hey, stop it! No sexual harassment!”

“If you don’t want to, you can call the police. Try to resist more seriously.”

“I would never do that! Come on, stop it…”

If she says she won’t call the police, there’s no reason for me to stop, so I keep squeezing her chest through her blouse.

Kinoka-neesan’s chest is really big.

Given that she’s a model, her style is good, and being able to have her is a lifetime achievement, even if it’s by force.

But if another man did the same thing to Kinoka-neesan, I might kill him.

“Hehe, you have nice tits.”

“Mouu… well, you can do what you want until you’re satisfied, but don’t do it again.”

“Hmm…”

When I squeeze her breasts harder, Kinoka-neesan stops resisting and submits to me.

She probably thinks that if she tries to resist more, we might become a nuisance for the neighbours.

I don’t like that reaction.

“Kinoka-neesan, do you like me?”

“I do. Of course, you’re my little brother.”

As I thought, it’s because I’m her little brother… if that’s the case, yesterday was for naught.

Is there even a brother who would do that kind of thing?

“I don’t care anymore. I’m going to take a bath.”

“Um, okay.”

I stop squeezing her breasts because I’m not having fun anymore, and I go to take a bath.

It’s a punishment… Kinoka-neesan is so sexy, and she teases me, so she needs more punishment.

To do that, I have to work out more.

Of course, I’m not losing to her now, but I have to train my body so that there’s no chance of that happening in the near future.

“It’s about time to sleep.”

It’s around midnight, and Kinoka-neesan is asleep, so I head to her room.

Hehe, I’m going to sneak into her room tonight.

The hot summer night is about to become a hot and intense night.

“Oh, I have to prepare this, too.”

I prepare duct tape and a jump rope for binding in case she resists.

I don’t want her to make any noise, and it’s just in case.

“I’m coming in. Oh, she’s sleeping.”

When I enter the room, Kinoka-neesan is sound asleep in her bed, and I turn off the fan she’s using.

Hehe, I’ll let her scream… I’m looking forward to seeing what her beautiful sleeping face will look like, and I’m possessed by an evil desire as I gently lift her blanket, and

“Hmm? Ih!?”

Kinoka-neesan lifts the blanket, and an unexpected scene appears before my eyes, and I couldn’t help but raise my voice.

“Mm… kya! Ha-Haru-kun? What’s wrong?”

“What’s wrong? You say. I came to sneak into your room, but… why are you naked?”

“Um… because it’s hot…”

Kinoka-neesan wakes up and sits up when she hears my voice, and I’m more surprised than her.

She’s… she’s naked—she usually doesn’t sleep naked, so why tonight?

Did she predict that I would come? Was she waiting for me, fully prepared?

“Oh, I told you not to do this kind of thing anymore. Come on, go back to sleep. You have school tomorrow.”

“Huh… I can’t back down now.”

“Huh? Kyaa!”

I’m told to go back, but I can’t calm down after seeing Kinoka-neesan naked.

I don’t feel bad about Kinoka-neesan at all, but I’m going to rape her.

“Hey, stop it… aah!”

I rape her, and she resists at first, but I quickly overpower her, tie her hands behind her back with a jump rope, and then we have sex.

Oh… it’s terrible. It’s terrible, but I don’t feel guilty, and I even get excited.

The night passes, and it’s a fun night, and I enjoy Kinoka-neesan’s body until I’m satisfied.
