Chapter 31

I follow the evenly spaced trees along the street with my eyes and walk against the wind.

I felt like a different person.

If this was me a few months ago, I would have been a creepy otaku who was just trying to be enthusiastic.

Miyu helped me choose clothes, introduced me to a good beauty salon, and I started working out.

Before I realised it, the world had changed.

I don't worry about other people looking at me, and I don't get nervous when someone calls out to me.

When my self-esteem was extremely low, I was ashamed of my existence just from talking to people.

I'm gross, my clothes are lame, my stories are boring, and my behavior is suspicious.

As those things improved one by one, I became able to have everyday conversations that I used to think were amazing when I looked at other people, and I started to think, 'What the hell, I'm just a normal person.'

...if it weren't for the fact that I felt an extraordinary sexual arousal towards my own little sister, I would have been a normal human being.

It can't be helped because it's that little sister.

My destination is the nearest station.

I usually use my bicycle, but it's not too far to walk.

I'm going to have a sleepover tonight, so I decided not to use a bicycle because I would need a parking space.

I stray off the familiar and take a different route.

I have plenty of time anyways.

If I exercise, my sexual desire will probably dissipate faster.

On my days off, I spent all my time on my otaku hobbies and was often cooped up playing games or on the Internet, so I would be in trouble if I was asked to spend a whole day outside playing.

Fortunately, though, that doesn't mean there's nothing to do.

I have to progress with the app that Suzuhara recommended, and I have to improve my online game level.

That's why I plan to spend the night in an internet cafe.

Until then, I'm probably going to an electronics store and looking at PC parts.

From the residential area to the station is the main street where the number of apartments begin to increase.

A large river was flowing along the way, and I could see students waiting on bicycles on the bridge.

There is a large park in this place, which is surrounded by nature and probably considered rural for people born in the modern age.

It sounds good, but that's all there is to it.

There are no entertainment facilities and it's not close to any schools, not to mention that the area a few stations away is fairly prosperous, so it's rare to find people coming here to play.

Even in the park, there were just families and couples relaxing on benches, and for someone like me who had no connection to the area, it was a place I didn't know even though it was my hometown.

The scenery is nice.

My chest feels refreshed.

I had accumulated a lot of sexual desire for Miyu, but his cock, which was still half-erect, was slowly losing its hardness.

"...What a huge apartment."

There was one high-rise apartment building that didn't match the scenery of the city.

I can't say that the access from the station is great, but it's within walking distance to a supermarket, so it's a good property.

Even though the land around here is cheap, the people who live in apartments like this are probably quite wealthy.

An auto-lock entrance separated by double doors.

The door is opened by a person coming out of the building.

Tip, tip, thin summer boots made a sound on the ground.

There was a woman with big breasts and a ponytail.

I thought it was a rich aunt, but it turned out to be an Onee-san with a very naughty body.

"--Wait, Yamamoto-san!?"

"Ara, Sotomichi-kun. Good morning."

It was a familiar face.

I guess the reason we never met on the way to school even though we were going home in the same direction was because she lived in a place like this.

"G-good morning."

"Fufufu. Somehow, Sotomichi-kun has turned more manly."

Yamamoto-san stood with her feet together.

"Thanks for that."

It's true that I've been getting my hair done and training my body, but my posture has always been good because of Miyu's influence.

When I wear proper clothes, I can talk to a beautiful woman like Yamamoto-san without hesitation when I run into her like this.

I'm glad it's fixed.

Thank you, Miyu.

I did something that made her angry, though.

"Sotomichi-kun is going out now?"

"Wandering after being kicked out by Miyu."

"Ara ara. Are you guys fighting or something?"

"I don't know why, but she's angry."

It's a little different from a fight.

"What about Yamamoto-san?"

"I'm going to pick up my little brothers. My parents will be away from home on a trip this Saturday and Sunday, so they asked me to keep them at home."

"You have a neglecting family too, huh."

Adults shouldn't have summer vacation, though.

I wonder if it's just a convenient time to rest.

I walked alongside Yamamoto-san.

Our destination seems to be the same.

"Yamamoto-san's little brother, huh. He must be very handsome."

It's the gene for such mature beauty.

He must have a tall and handsome figure.

"Not at all. He's really small. He looks like a girl."

Yamamoto-san strokes the air with the back of her hand resting on the base of a large mountain she created with the straps of a pouch she wears over her shoulder.

"That's why I often dress him up as a woman and play around with him."

"You're a terrible older sister..."

At school, Yamamoto-san is like an angel who is kind to everyone.

I'm sure she would dominate the world at home.

If I lived with such an excellent and beautiful older sister, I wouldn't be able to resist her.

Though, compared to my little sister, it's practically a cakewalk.

"Huh? Don't your little brothers live together with you?"

What does she mean, she's going to pick them up to keep them at home?

Families live together, don't they?

Not to mention, she's a student.

I don't care if they are divorced or separated, but her parents are close enough to go on a trip.

"Ah... t-that's...!"

Yamamoto-san's look of 'I've done it.'

She stopped in front of the park entrance and started playing with her hair.

"U-um… my little brothers are staying at a relative's house… and they're coming back when their parents are going on a trip…"

"If your parents are gone, wouldn't it be better to leave them in your relative's care then?"

"Ha--!"

Yamamoto-san's expression grows stiffer.

"Ahhh yeah! Yes! That's right! That's why we originally intended on keeping them there, but my relatives are relatives and it became inconvenient, so we decided to keep them at home!"

"Haah. Are you looking after them?"

"When I say 'keep them', it means to bring them home! Um, but when I say 'keeping them', it means to leave it with them! So, uh, it doesn't mean that I live alone, okay!?"

Yamamoto-san denied it, shaking her head, hands, and ponytail as much as she could.

Yamamoto-san is really bad at lying.

I guess it's because of this straightforwardness that other girls don't feel jealous of her.

"It's unusual for a high school student to live alone."

"Like I said, um... uuu..."

Yamamoto-san crouched down holding her head.

It hurts when people look at us as they pass by.

I put on a fake smile and pretended that I wasn't doing anything, and waited for a few minutes.

Yamamoto-san checked her watch and pulled me into the park.

"You know, Sotomichi-kun."

Sitting on a park bench next to a beautiful girl.

The bench was cold as the sun was still low.

"Please keep this a secret from everyone!"

With a clap, she put her hands together and worshipped me.

The face that desperately closes its eyes is also cute.

"I don't mind that. Suzuhara knows anyways, right? ...Sorry for the inappropriate question."

"Ahaha. Yeah, that's a difficult question to answer. Even Suzuhara-kun doesn't know that I live alone. I've never had anyone other than my family in that room."

Yamamoto-san looks at the fountain uncomfortably.

She hasn't told anyone but her family, huh.

Even though it was a coincidence, she did something bad, didn't she.

The room where Yamamoto-san lives belongs to her uncle.

Yamamoto-san was told that she could live at half price, so she manages to make ends meet with her parents' allowance and her part-time job.

"I see. Well, I won't tell anyone. I won't come over here to check on you for no reason."

"Yeah, thanks."

She expresses her gratitude and leans down.

Yamamoto-san sighed deeply.

"I don't think you can trust me, though."

After all, it's a verbal agreement, and I don't have a good enough relationship with her for her to trust in me.

"Ah, no! That's not true. I was planning to ask Sotomichi-kun to tell me his secret, but I wonder why it turned out like this..."

By the way, yesterday Yamamoto-san asked me persistently if I had anything to ask of her.

Yamamoto-san was talking about trading each other's secret, but I just inadvertently gained an advantage.

Shall I tell her about my troubles as a guarantee that I won't say anything else?

If I blur out the fact that I can't bust a nut to Miyu, I might be able to discuss the matter.

While I was thinking about this, Yamamoto-san's smartphone received a call.

'A-kun♥' is displayed on the display.

I guess it's her little brother.

Looks like they get along.

"Hey, you! How long are you planning on making us wait, you pig!"

This energy from the first word.

His tone was masculine, but his voice was childish.

"Yes, yes, Onee-chan will come soon. Just wait a little longer."

"While you're walking around like a cow, go and buy some ice cream already!"

"Don't get so angry. Listen to what Mi-kun says and stay calm."

"Shut uup! If you don't come back in three seconds, it'll be two ice creams! Bye!"

A phone call that suddenly cut off.

Yamamoto-san sighed with her hands on her cheeks.

"It’s quite different from the image I'd heard."

"This younger child is very naughty. If I give him a kiss on the cheek, he'll punch me."

"I think it would be better to discipline him properly."

You won't become a decent man by hitting such a beautiful girl."

"Disciplining him, why would I do such a thing... Onee-san is supposed to embrace her little brother with unsparing love, you know."

Yamamoto-san cradled her large chest in her arms.

"Then you'll suffocate him with your breasts until only the whites of his eyes remain."

"Not another outrageous thing..."

I take back everything I said.

No matter how you look at it, it's Yamamoto-san's fault that he became this mischievous.

"He's at the age of adolescence. If you do something like that, I think he'll grow even more resentful of you."

By his voice, her little brother is an elementary school student.

No matter how beautiful she is, he would hate excessive physical contact from his sister.

Yamamoto-san thought about it for a moment, and then her face returned to being enchanted.

"Isn’t it cuter to be rebellious?"

Ah, this is a no-good older sister.

"When I put him in girl's clothes he became a bit shy afterwards, he came to me and was like 'I'll listen to you, let's get along...' Ufufu. He's like that on the phone, but we're getting along just fine."

"I-I see."

Her way of love is way too distorted.

I can't believe Yamamoto-san had such a side to her.

But well, I guess she did always have an Onee-san's personality even at school.

Besides, I'm in no position to judge other people.

After doing something so erotic with my real little sister, I got so excited that I almost raped her, and I'm accumulating so much sexual desire.

"Nn? Huh!?"

I immediately grabbed my crotch.

Even though I should have been so sexually aroused, I sat next to Yamamoto-san and didn't seem to react as if I were.

"What happened? Is it gone?"

"You might be right."

I turn around and check inside my pants.

It was quite small, but there was indeed the symbol of a man there.

This is not good.

Until I left home, I was so worried about how I was going to get by without busting a nut.

I've had an erection before, but today this is a situation where I absolutely have to get one.

"Um, Yamamoto-san, can I ask you a strange favour?"

"Hmmhmm. Alright. For that favour, you'll owe me one, okay?"

Yamamoto-san held up a finger and nodded enthusiastically.

Was she always this tactless.

"Uh... can I smell your hair...?"

The place where I sense girls' pheromones the most.

If I smell Yamamoto-san, a motherly mass, I'm bound to get excited.

There's no way I wouldn't be excited.

As for Yamamoto-san, her face stiffened slightly.

"Umm... Sotomichi-kun? That's... more gross than being asked to have sex with me...?"

"Y-yeah. Sorry."

I got flustered and blurted it out.

Even though we were talking in a nice atmosphere.

I hope she doesn't hate me.

"Hmm... Well, if that's what Sotomichi-kun asks, I won't refuse to it."

"Eh, are you serious!? Are you sure!?"

I unexpectedly received an OK.

It's unlikely that there exists a possibility where I'm the only one special to Yamamoto-san.

Do you really want to owe me that much?

"Yeah. ...yeah? Eh?"

After consenting, a question mark appears in Yamamoto-san's mind.

I guess I was so pleased that I created unnecessary doubts in her.

"Which one is Sotomichi-kun asking for?"

"Which one? About what?"

Either way, I just want her to let me smell her hair.

"Eh!? You meant that!? That is okay!?"

Is that what she means when she said she'd rather be asked to have sex with me?

Is that option available?

"Y-you meant over there after all!? Um, uh, l-lewd stuff is a little... you know? I thought I was giving permission to my hair... "

"Ah, yeah. That's right."

That startled me.

What a huge misunderstanding.

Where in the world would there be people who come up and immediately ask to have sex?

"Well, if it's Sotomichi-kun, I can give it some thought."

"Why is that."

No matter how I think about it, she doesn't like me.

It bothers me that the girls around me are too tolerant of sex.

"Why did you care about the smell of my hair?"

"Ahh, no, it's not like that. Sorry. Don't worry about it."

I can't say that I wanted to smell it to see if it would make me erect.

"Eh, what what? I'm curious."

"No, it's quite a difficult topic to talk about... You see, it's related to the troubles I talked about at school before."

"Ah-yeah! That! Tell me! I'll fix them for you, so. And then you'll owe me twice."

Wait what?

Even though I haven't experienced the smell of her hair or had sex with her, I feel like I owe her some sort of debt already.

"Let's see..."

Shall I say it?

"Actually, I..."

Possibly, if it's Yamamoto-san.

She would be able to solve my troubles.

Moreover, the atmosphere seems to allow my erotic requests.

She also wants to make me owe her.

If she can solve it, that is.

"It looks like I have erectile dysfunction."

Maybe she'll let me have sex with her.

"...I know that, though?"

After the wind blows, she says a single comment.

Yamamoto-san said, with a face that was like 'Is that all?'

"How do you know?"

"Look, when I was naked in the changing room. Don't you know what Miyu-chan asked me to do?"

The time where Yamamoto-san got naked in the changing room was when Miyu and I went to the shopping mall to buy clothes.

There was a lot going on like her breaking up with Suzuhara, so I couldn't think straight.

Speaking of which, Yamamoto-san took a picture of my erection and sent it to Miyu.

At that time, huh.

"Miyu-chan asked me to help her because 'Onii-chan seems to be suffering from erectile dysfunction.' As it turned out, doing so was a condition for her to help me say goodbye to Suzuhara-kun."

"Was that so? I had no idea."

That Miyu doesn't tell me anything and keeps pulling strings around.

Thanks to her, I have some delicious memories, though.

"But, Sotomichi-kun. At that time, it grew a lot, didn't it?"

"That's true, but."

How do I resolve the matter?

As expected, I can't say that I can no longer get erections with other people after doing so many naughty things with my little sister.

"Since then, it's gotten worse. Actually, I think it's more of an ejaculation disorder than erectile dysfunction. It's more like that."

"Hmmhmm. Basically, it'll get big, but it won't pew pew."

It's helpful to talk to a girl who has experience.

The way she expresses ejaculation gives me chills though.

"Hmm, maybe that means that in the end, you won't be able to solve your problems unless you do something naughty?"

"I guess so."

If I could use Yamamoto-san as my fap material and masturbate, that would be one solution.

Let's keep quiet until Yamamoto-san notices that.

This may be my last chance.

In order to get back to a life where I can live without relying on Miyu to ejaculate, I need the cooperation of other girls.

Her appearance is impeccable.

For some reason, she's cooperative with me.

This is an unprecedented opportunity.

I have to make it into something.

If that happens, Miyu's burden will be reduced.

"Is that so. I can definitely solve the problem, but..."

Yamamoto-san glances at me with a troubled look on her face.

"Did Sotomichi-kun hear about my troubles from Suzuhara-kun?"

"Yamamoto-san's troubles? You mean, the one you talked about in the library before?"

"Yeah yeah."

"I haven't heard, and I have no idea."

"Hmm... I see. Then, nevermind."

Yamamoto-san believed my words easily, as if I had conveyed my sincere feelings that I didn't know anything at all.

I wonder what part of the conversation we had earlier was connected to Yamamoto-san's troubles.

“The point is just for you to cum, right?”

"Well, I guess so."

"Then let's just finish things up there."

Yamamoto-san points to a public restroom.

The idea is completely f**ked up, but is it okay, Yamamoto-san?

"My deepest apologies, but I can't do it today."

"Really? What about tomorrow?"

"I can't do that either."

"Whyy?"

My little sister has banned me from ejaculating... of course I can't say that.

"Is it really no good? Even late at night or early in the morning?"

"Ah-, hmm... it's possible on Sunday midnight, but... it'll be difficult..."

"Ugh... well, Monday is the last day before summer vacation, so I guess it'll work out somehow... uuu... why not Saturday..."

It seems that she really wants to make the loan to me by Monday.

Is it really something she has to do even if she has to sell her beautiful body?

I got no idea.

The feelings of a girl.

Haven't the foggiest...

"Your little brother is probably waiting too. I think we should go now, shouldn't we?"

"Why are you digressing?"

"There are circumstances that I can't tell you either."

"Just like that again, full of secrets."

Yamamoto-san looks dissatisfied but raises his hips from the bench.

"Let me know when it's convenient for you. Just ask Miyu-chan for my contact information."

"I got it."

Yamamoto-san turns her back on me and leaves the park.

After turning the gate, she ran fast.

"I don't know about girls, huh..."

I held my head and sat on the bench for a while.

Then I stopped by the electronics store and wandered around the city, consulting my wallet for impossible wishes, like wanting to expand my computer's memory for gaming.

My internet cafe reservation starts in the evening.

Until then, I spent my time in more open cafes, securing power, playing apps, going to the arcade, playing apps, going to the bookstore, playing apps, going to the clothing store, and on and on.

"I see you're booking a night plan. Would you like a Free Time Pack until noon tomorrow?"

"Yes, please."

I don't have any plans tomorrow, so I'll give myself plenty of time.

Although it was Miyu's order, staying at an internet cafe was quite the pain.

How many part-time jobs should I schedule into my summer vacation?

I was given a card key and went to my private room.

It's an internet cafe a notch higher than the one I visited with Sachiko last time.

First, I thoroughly read through some mangas.

There are some works that I stopped mid-read.

If I read them here, I can consider if I've earned my money's worth by the number of books I read.

The spines lined up neatly on the bookshelf are nice.

I feel exhilarated whenever I see it.

It's getting late, so I'm starting to get horny.

I can properly spend the night without ejaculating, right?

"Oh my, oh my. It's Miyu's Onii-san, isn't it?"

It came from the corner of the bookshelf.

There was no doubt that that voice sounded sarcastic.

It belonged to that worthless woman.

"Yuka, huh... You really like ambushing people in internet cafes."

I like the atmosphere. Isn't there something obscene about the air?"

"It seems you really want to turn internet cafes into a place to do sexual stuff."

Though that's not something I can say after actually doing those things.

"Mufufu. That's what you say, but isn't Onii-san also overflowing with erotic desire?"

With that, Yuka stared at my swollen crotch.

Oh, that can't be good.

When I hear Yuka's voice, I can't help but remember Miyu's punishment.

"There's a deeper meaning behind this."

"Heeh. What kind? Onii-san was actually a lolicon this whole time? Ah, that was already a well-known fact. Pi-kuku-."

This bastard... I don't think I'll ever be able to get along with this girl.

"Well, it's fine, you know? If it's Onii-san, there's no way Yuka won't help you feel refreshed, you know?"

Moving closer and closer, Yuka traces the chuck of my pants with her fingertips.

"H-hey."

Why are you girls so aggressive towards me?

"I'm feeling really good today. It's all th-an-ks to Onii-san, so I feel like I want to repay you in some small way."

"Ah? Thanks to me?"

What is this girl talking about?

Since we last met at a family restaurant, Yuka and I have exchanged messages on our smartphones, and I haven't done anything for her to thank me for anything...

"Ah--!!"

That thing about the family restaurant.

I forgot to tell Miyu.

Yuka was definitely thinking about some good-for-nothing thing.

And she said it was all thanks to me.

Maybe, no, there's no doubt about it.

The reason why Miyu is angry.

"Muufufu. Do you remember? Onii-san told me. Miyu's weakness. Why didn't you notice such a simple thing?"

With a sly grin on her face, Yuka pulled out a photo on her smartphone.

What was photographed there was a naked female student.

There is no mistaking the appearance of this extremely beautiful girl.

It's Haruka's.

"The other day, we had a health checkup. There, I was able to take a few nice pictures like this. They're great, aren't they? Miyu's benefactor."

It was the worst possible situation.

I was taking it too lightly.

It wouldn't be strange if Miyu got mad about this.

And I am an accomplice in this crime.

"Miyu's pale face when I showed her this photo. She was so cute I couldn't help but... haah..."

Yuka's expression was ecstatic.

Metamorphosis, abnormality.

It was out of the ordinary.

"Wait, you're going to die, you know."

"Haah? What are you saying? I told Miyu that if she disobeyed me, I would spread this photo around, you know? Miyu is already my slave. Tomorrow will be the day when I'm going to make her play with me the whole day."

Was that the reason Miyu asked me to leave the house for a day?

Because she didn't want to be seen humiliated.

She did such a thing in order to shut me out.

"Why are you doing this? Doesn't Yuka like Miyu?"

"I like her, you know? I still like her even now. But I couldn't reach her. For four years, Miyu never took me seriously. She could have been a little nicer to me. She didn't smile at me even once. It's Miyu's fault. Everything, all of it."

What a mess of words and actions.

However, I can't just dismiss everything she does as all wrong.

It doesn't change the fact that Yuka is evil, but.

The reason for this is also because Miyu's influence on her is too great.

"Wait what? Wait what wait what? Don't tell me, you didn't notice?"

"W-what is it."

Yuka opens her eyes and looks into mine.

Honestly, it's pretty scary.

"Tomorrow, I'm going to make Miyu do a lot of embarrassing things, right? After I take that photo, who do you think will be my slave next?"

She waves her smartphone at me and provokes me.

A person in trouble, held hostage by an embarrassing photo of Miyu.

Two people come to mind.

"Are you trying to threaten Haruka too, using those two as tools to threaten each other?"

"Nonono. Haruka doesn't protect Miyu. She likes her as a love doll, not as a lover. Besides, Haruka has a very bad personality even though she looks like that. She's even worse than Miyu."

Yuka's voice was full of resentment.

After being subjected to so much torture, it's not hard to see why she might be disgusted though.

Assuming that Haruka isn't the one she's threatening, what remains is, of course.

"Me, huh."

"That's right. Mufu. Onii-san, it seems to be accumulating a lot. You can give me that sperm, right?"

"No way, are you planning on involving me and becoming family...?"

"Yees! There are many girls who want to become Miyu's sister-in-law. Onii-san's sperm is in high demand, isn't it?"

A very unpleasant fact has come to light.

Miyu is so popular that the devil's hand is sneaking up on me.

"Well, I won't do anything bad. You're my benefactor in many ways. Please look forward to seeing Miyu's naughty videos when I send them to you. Until then, please don't settle for some erotic videos from the internet, okay?"

Yuka gave me a soft touch over my pants, then smiled and headed towards the checkout.

Miyu was forced into a corner because of me.

I gave her such an idea.

No wonder Miyu's angry.

I want to stop Yuka, even if it's by force.

If things get complicated and the situation worsens, there is no going back.

Even if I destroy her smartphone, it doesn't mean the data's erased.

What should I say to apologise to Miyu?

I wonder if she'll forgive me in the first place.

My mind was full of anxiety.

I can't just apologize over email or over the phone.

Until 6 p.m. on Sunday when I'm allowed to go home.

I focused on games and manga, just waiting for the time to pass.

Even after leaving the internet cafe, I still felt uneasy.

As the time approaches to go home, my heart rate increases.

The time which I had been wishing to pass so quickly, is now causing me to feel contrary with only a few minutes left to spare.

When I finally arrived.

In front of my house.

It was 6 p.m. when I put my hand on the front door.

The lock was open.

When you open the door, there it is.

Miyu, the same as always, was waiting to greet me with her hands folded in front of her.

"Welcome back. Onii-chan."

"Y-yeah..."

It's normal.

Too normal.

This is abnormal.

Yuka was supposed to be at the house.

I can't feel anger or sadness.

"So..."

"Right away, Onii-chan. I'll have you listen to the second part of my order."

Miyu tells me to go up to the house, and climbs the stairs.

"Onii-chan, you like onaholes, right?"

"Well, I don't hate them, rather, if I had to pick one, I like them..."

"That so, Onii-chan."

Miyu suddenly stopped.

I was about to collide with her, so I quickly pulled myself away.

We were in front of my room.

"I wanted to ask Onii-chan to develop a new onahole."

Miyu picks up a small box that was left in front of my room and shows it to me.

A 0.01 millimetre ultra-thin condom.

It was a luxury product containing five pieces.

"You'll listen to my orders, right? Onii-chan."

Before I knew it, Miyu's eyes had lost its human glow.

Her eyes are so dark I can almost feel its muddy darkness.

Miyu's hand rubs my crotch.

My erection was so large that it represented the amount of semen he had accumulated so far.

"A-aah..."

At that moment, I finally understood the meaning of the warning signals that my brain had been sending out yesterday morning.

Miyu opens the door to my room.

Inside the room was a large cardboard box.

One side of it had been hollowed out, leaving only the buttocks exposed.

In a supine position, touching the thighs.

Just like a large onahole I insert in missionary position.

But that size, that texture.

No matter how I look at it, it just looks like a real person.

"H-hey, Miyu."

"It's too late to refuse now. You'll listen to my orders, right?"

Miyu presses the condom box against my chest and glares at me with cold eyes.

"There are five rubbers in there. All you have to do is use that onahole and fill all five with semen. Then Onii-chan will be free. It's an easy job. You did it."

A very cold, very flat voice.

I have no right to refuse.

Obey any orders.

I had assumed that there would indeed be a limit.

This little sister made me cross that line.

Today is my last day as a proper human being.

It was an inexcusable order to rape.

(T/N: I don't know why the author chose to write 'little brothers' in the original work when it was implied she only had one, so take it with a grain of salt I guess)
