It was a sight I had never imagined.

My room has lost all light from the window.

A large cardboard box was placed there.

The box reveals only the buttocks of a woman, lying on her back.

Miyu called it an onahole.

Then she ordered me to fill the condoms with semen using that fleshy female organ, which by all accounts was the real thing.

On one hand, a slave.

On another hand, a piece of equipment.

What I was about to do was insert my cock into that vagina, which was definitely Yuka's, without permission.

"Miyu... this definitely is a crime... isn't it?"

This is beyond the scope of punishment.

If Yuka feels like it, she can sue me and get me arrested.

"So what?"

Miyu didn't just say it out loud; she really meant what she said.

"So what if it's a crime?"

Miyu didn't care and led me in front of the now-onahole Yuka.

Her body, protruding from below the navel to the ischial bones, has her legs folded back into the cardboard box from her knees up, her crotch spread out.

Even though the cardboard box had been extended with some handcraft, it still wasn't large enough, only fitting with her knees stretched out and tied up.

She must be in a pretty tight posture.

Smooth buttock curves.

When I touch it, I can feel the warmth of a person.

This is real.

A real person was made into an onahole.

"This is Yuka, isn't it?"

When I tried pinching the meat, there wasn't any reaction.

I wonder if she's asleep.

If she was given sleeping pills, wouldn't it be better for Yuka if I were to finish it while she was sleeping?

Either way, it's not something I can do with normal nerves.

They've gone mad.

Yuka, Miyu, why are you all so twisted?

"If this becomes a matter with the police, I'll be expelled from school. Miyu will also be suspended from school at the very least. If Yuka gets raped, she'll be traumatised for the rest of her life. No one will be happy like this."

I thought I was making a good argument.

There is nothing wrong with my words.

I was absolutely sure I was right.

"That's only if it's reported."

As long as Yuka doesn't say anything, it doesn't matter what I do.

Miyu's theory is that if it's not recognised, it doesn't exist.

"In the first place, Yuka was the one who committed a crime first. Dealing with it within the family instead of with law enforcement, aren't I being the kind one here?"

Miyu brings her face closer and looks at me.

It felt like the yakuza was grabbing me around the chest.

"Yuka will repent, I will no longer be pranked, and Onii-chan will be able to return the favour. Everyone will benefit. Everyone will be happy."

The voice of Miyu flowed to my ears.

With each word, the burden in my heart disappears.

Even though I knew in my head that it was a messed up statement.

Hearing Miyu's words, I felt somewhat at ease.

It was like I was being hypnotised.

"Take off your clothes."

Miyu's orders were absolute.

I take off my shirt, my pants, and without asking, I also take off my underwear.

I, her older brother, stripped naked in front my little sister.

The cock that had been teased so much in my crotch was already arched upwards.

That alone is humorous, and yet.

In a matter of time, I have to shake my hips hard towards this onahole.

"Here. The first one."

Miyu opened the condom box, tore off a piece of wrapping paper and handed it to me.

"Hold on until the very last minute and don't just freely cum, okay."

Miyu traced the curve of my back muscles with her fingertips.

"Fuah... ah..."

My voice leaks in numbing pleasure.

The feel of Miyu's hand, which she usually doesn't want to touch with.

It was too stimulating for me, who was on the verge of an outburst.

"If you're too excited to put up with raping a junior high school student in front of your little sister, I'll forgive you though."

Miyu ran her index and middle fingers into Yuka's secret cleavage and opened it sideways.

A sticky liquid leaks out from the fleshy hole, and Miyu's fingers pulls a thread as she releases her hand.

"For me, that kind of thing is... But, it's been accumulating since the day before yesterday, so it might be faster than I thought."

I used to ejaculate many times every day, but suddenly I had to stop masturbating.

I can't stand it anymore.

"I don't agree with that. Because that's how it is, right? From my point of view, it doesn't just seem like you want to get it over with quickly."

Miyu's opinion boils down to this.

Even if my true feelings are to get things done quickly, I should just follow her orders so that she doesn't realise that.

"For example, let's see. If Onii-chan rapes a girl while screaming that 'it feels good, it feels good', your little sister might be satisfied with the fact that you ejaculate right away."

It was the devil.

This is not only a punishment for Yuka, but also a punishment for me.

For this little sister of mine, what is most important is sincerity.

She implicitly tells me that if I want to apologise from the bottom of my heart, there's nothing I can't do.

"It's about time you did it."

Miyu presses the head of my penis into missionary position with her fingers and sinks it into Yuka's crack.

I had no choice but to insert it.

At least while Yuka is asleep.

I have no choice but to do it without stimulating her as much as possible.

I gulp and swallow.

My glans, which is halfway inside her vagina, feels Yuka's body temperature.

If my glans rubs the vaginal flesh, there's no doubt it's considered rape at that point.

I only met Yuka a few times.

We're not close enough to have sex.

Although she did say that she would be willing to become pregnant with my child in order to become family with Miyu.

It would be foolish to take seriously the words that come out on the spur of the moment.

If I bend down a little further, I can enter her.

I can't make excuses just because Miyu ordered me to.

From now on, I will be taking from Yuka.

"Wha--!"

With a twitch, Yuka's butt muscles contracted.

My hips buck up in amazement.

That movement strongly stimulated the front of Yuka's vagina.

"Nn... Nnh-!! Nnnuuunh!!"

A muffled scream can be heard coming from inside the cardboard box.

Yuka is screaming.

Realizing that she is about to get raped, she desperately resists.

"Arara. Even though I left you there for five hours. I wish you could just sleep."

Miyu's smacks Yuka's butt hard with a 'slap!'

With just that, Yuka, who was restrained inside the cardboard box, let out a pained roar as if she had been stabbed with a knife.

"M-Miyu! Why are you explaining to Yuka!?"

Fear of relapse.

Does Yuka know that she will be raped by me?

"Some friends of Onii-chan were eager to lose their virginity, so I've told them to leave it to me."

Miyu was telling lies to Yuka.

Yuka thinks she will be raped not by me but by a stranger.

This is the worst lie ever.

Yuka knows what I looked like before Miyu changed me, and that I was recruiting a girlfriend for sex.

To Yuka, I am a creature in the same category as a boring otaku.

What kind of image does Yuka have when she hears about such an otaku's friend's virginity?

I don't have to think about it.

A gross otaku with a communication disorder.

A fat person who can't control himself.

Or maybe an old man that no one wants to hang out with.

Now that I can meet people from all walks of life offline, my acquaintances are not necessarily my school friends.

Yuka imagines being raped one after another by such men.

"NnneeeEHe-!! Nneh, nnnheeehee!!"

Yuka can't speak properly because her mouth is covered.

But I can still get it.

'Stop it!! Stop ittttTT!!'

She's resisting.

In this desperate situation.

She begged me not to do it.

I can hear the sound of my heart beating.

I'm going to rape this girl who hates me so much.

"-haah... guh..."

I can't breathe properly.

I haven't even moved yet, yet I'm so nervous and out of breath.

"Onii-chan, this."

Miyu got impatient and showed me the screen of her smartphone as I was reluctant to insert myself.

What was displayed there was a social media timeline.

It was a site where you could anonymously send messages to an unspecified number of people.

"T-that's...!?"

The moment I saw that screen, I was terrified.

What connected in my head was a hidden photograph of Haruka that Yuka showed me at the internet cafe.

You can also post images to anonymous sites.

That could only mean one thing.

"Yes. It's already posted on the internet. Haruka's naked body."

Images are displayed one after another, scrolling the screen with my finger.

"Wha--!?"

The reason why Miyu is furious is not just because of Haruka's secretly taken photos.

"Miyu..."

Even Miyu's naked body was uploaded.

She was in the middle of taking off her bra to measure her chest circumference.

Yuka had posted the photo on social media, which clearly showed the part of Miyu that she had the most complex about.

"Luckily, no one's seen it yet because it was posted on a newly created private account. But it's the times we live in. I don't know how they can be salvaged. This woman has caused damage to mine and Haruka's bodies. That's why I want her to lose the same thing."

The punishment Miyu imposed on Yuka.

Although it was Yuka's imagination, it was about losing her virginity through gang rape.

"Yuka, you've told me many times. That it was thanks to Onii-chan you can make me obey you. Hey, Onii-chan. Are you still not going to rape her?"

This is Yuka and I's fault.

We have no choice but to settle the bill.

Together.

"Yuka, sorry...!"

"Nnnnhh!! NnnuuuuUUu!!"

I firmly grabbed Yuka's buttocks as her resistance intensified.

Smush, smush, as my cock goes in.

"NnneeeEEee!! NNgakyaaAAagaaaaAAAHH!!"

Yuka was jittery and out of control, but she wasn't able to move as fast as she could.

The writhing flesh wall exquisitely stimulates my penis as it tries to narrow the entrance to the vagina to prevent the penetration of my penis.

"NnAaAAAAHH!! AAAaAAHH!! NNGUHNnaaaAAAH!!"

My cock goes in while pushing out her love juice.

Half of it was inserted into her vagina, and I still thrust my hips forward.

"Ahh... ah...!!"

It had been a long time since I had tasted a woman's flesh hole, and it felt narrow but soft.

Guilt and pleasure creep up my erogenous zones as a man.

My penis has reached the depths.

The tip of it gouged Yuka's cervix.

"Nnnngggaa-aaaAAaAGYAAaaAAAA!!"

It was a scream that sounded like her throat was being sliced.

Yuka screamed with all her strength, so much so that it wouldn't be strange if she was vomiting blood inside this cardboard box.

Even though her sounds were leaking out of a sealed space, it was loud enough for me, who was right next to her, to hear it clearly.

Screams of resistance to rape.

Sobbing at having her purity tainted.

Realising the gravity of the crime I had committed, I felt unstoppable regret and tears.

Everything was very real to my ears.

My heart has darkened to the point it's becoming hard to breathe.

Still, I kept shaking my hips.

Pang, pang, pang, pang.

Jub, jub, guchu, guchu.

Every time the sound of water plays as I strike my hips against her, Yuka screams.

Even though I'm not even angry or scolding her, I'm raping a girl who can't even tell the difference between right and wrong.

An act that is unbelievable as a human being.

Even after being penetrated, Yuka continues to beg, 'Stop! Stop!'

"Aaah... Yuka, sorry... Yuka...... Ah...!"

The ultra-thin condom directly conveys the feeling of rubbing against Yuka's vaginal flesh.

Feels good.

There's no way I can't find pleasure in something like this.

"It feels good... ahh... it feels good...!!"

Miyu teased me, prohibited me from masturbating, and now the feeling of having my swollen penis screwed into this narrow meat hole is irresistible.

Even though Yuka resisted, the tightening only became stronger.

The pressure that rubs my cock increases even more.

"NgaaAAH!! Nnnuuununuu!! Nnh!! Nguguguuuu!!"

Thump, thump, the sound of hitting the floor echoed.

Yuka hit her head to show that she was inside.

I already knew you were a real person.

Maybe there was a cushion placed on her head, but the sound of Yuka hitting her head didn't sound like a violent blow.

Even though her body was tightly restrained, her lower body still moved, showing the intensity of her resistance.

Yuka must feel that the rod inserted in her vagina is quite large.

My cock, which had expanded and became filled with blood, was no longer the weak penis it had been before.

Masturbating with Miyu on repeated occasions has definitely increased its size.

And I'm forcibly inserting it into the vagina of such a small girl.

There's no way it doesn't feel good.

"Aaahhh... cu, cumming... cumming...!!"

A violent back and forth stroke of the hips.

The honey overflowing from the meat pot bursts out.

"Nnnnnh!! NnyyaaaagaAAHH!! GuyagaaAAAAHH!!"

"Cumming... uuu... AaaAAH-!"

The semen I had accumulated for two days is spit out in Yuka's vagina.

My penis, which expanded with each ejaculation, further widened Yuka's narrow vagina, and Yuka must have instinctively understood that she was being ejaculated in vaginally, along with the intensity of the strokes.

As I was immersed in the afterglow of ejaculation, I heard the voice of a sobbing girl coming from this inorganic box.

"Aah......"

I went ahead and did it.

Finally, I committed the crime.

Even from my point of view, she's still a girl who hasn't left the frame of a child.

A law that should never be ignored.

"Thank you for your hard work, Onii-chan. Anyways, you've finished the first round."

A condom filled with a large amount of semen is hanging from the penis that was pulled out of Yuka's vagina.

Miyu pulls it out, ties it up and hands me a new one.

"Ara."

After Miyu tied the condom, she turned her hand inside out and looked back at it.

What was on her fingertips was red.

A thin red transparent liquid was sticking onto Miyu's fingertips.

"She must have been playing with her toys quite a bit. I wonder if there was any left over."

The proof that Yuka's hymen had been broken was plastered all over the condom.

When I looked closely, I noticed that red juice was dripping from Yuka's secret hole.

I raped a virgin.

Even though it was completely obvious.

Seeing real blood gives me goosebumps.

"Well, nevermind that. Do it again."

While being overwhelmed with guilt, Miyu brushes off the fact that she lost her virginity with a casual 'Well, nevermind that.'

Even though Yuka was crying.

She was saddened by the loss of her virginity to a stranger.

That's not something I, the perpetrator, could have said.

I hate this sexual desire that has caused me to ejaculate so much that the rubber reservoir had swollen and yet, is still making me hard.

"Nguh... uuu... uuuu..."

Sniffling and groaning sounds echoed through the cardboard.

My heart was twitching.

I feel so guilty after doing something like this, how can I pretend to be the victim?

Both Miyu and Yuka lost something important.

I'm the one who took that from both of them.

"Onii-chan, are you reflecting properly?"

"Of course..."

"Then you can do it without me giving you any instructions, right?"

Miyu makes me grip the condom I'm holding tighter once again.

I understand.

This girl is the villain who tried to expose Miyu and Haruka's naked bodies to the public.

A culprit who deserves to be brought to justice.

I'm a bad person so to speak.

I took on the job that no one else wanted to do as punishment.

I will live with a feeling of guilt that will continue to drag me down for the rest of my life.

That's the price I have to pay.

"Uu-... uuu..."

"Yuka, sorry."

"Uuuu... n, nnh!? N, nhh-!! NnnnuuuuunnununuuUUU!! NnnaaaaAAAAaaAAHH!!"

I put the rubber on my penis again and inserted it into Yuka's vagina.

Yuka's meat jar, which was still smeared with extreme excitement, had plenty of honey remaining inside.

A scream that gets louder with each thrust of my hips.

A body that moves violently to resist.

Both of them are getting weaker and weaker.

Originally, Yuka's body had been deprived of considerable physical strength by the time she was restrained by this cardboard box.

If she was in a normal state of mind, she wouldn't have been able to go wild like this.

"Yukaa, Yukaa... Yukaaaaa......!!"

"Uguh... Uuuuguh... UuuUUuuUuUUunnnuuguuUu!!"

The voice that was screaming with all its might turned into a whimper.

I can see her gritting her teeth, trying to resist this cruel fate.

This girl did something bad.

A person who deserves to be punished.

She needs to be punished because she's a bad girl.

The thought that made me want to stop and apologise was overwritten with criticism of Yuka over and over again, as I shifted the blame towards Yuka.

"Uu-... uu-... uguh..."

Yuka soon stopped moving her body.

In the quiet space, only my heavy breathing fills the void.

"Haah... haah-...-aaah...... fuuh..."

Kuchu, kuchu, kuchu.

The condom entangles Yuka's honey and scrapes it out.

No matter how much we hate each other, we're in a state where we can have sex with each other.

It's a 2D cliche that the body is honest.

I couldn't imagine a girl's body really feeling this way.

"Ah... ahhh...!"

Still, as a man, I feel it.

Male instinct.

I don't care if the other person accepts me or not, as soon as I rub my genitals against their wet flesh, I feel a surge of excitement.

The feeling of ejaculation.

A human body mechanism created to preserve the species.

That's why I continue to rape Yuka wholeheartedly.

My testicles were rising and preparing to eject sperm into her vagina again.

Her cervix and my urethral opening kiss repeatedly as my cock moves back and forth violently.

While sloppily dripping her love juices, Yuka was alternating between experiencing the convulsions of her diaphragm caused by despair and the stimulation of being penetrated deep inside her vagina.

"Yuka, ahh... Yukaa... Yuka, I... again...!"

"AAaaauUUuuuU... ah! UuuUUuguh! u... eguh... uuu... aaaAAH!"

I'm already about to cum.

Making a girl, who is resisting, cry and then ejaculating.

A stroke that gets larger towards the finish.

Yuka already knew that it was a movement to ejaculation.

“Aaah, Yuka, haah-, coming, cumming-…!!"

"AaaaANNNH! NgagagaaAAtsuGUH! Uuugugunuu!!"

The amount of semen pouring out was the same as the first time.

Every time my cock expanded and contracted due to ejaculation, my vision kept flashing and going black, and my brain and heart became so hot that it felt like there was a short circuit.

"Nn. Thank you for your hard work. Take off the rubber."

In contrast, Miyu remained calm.

For Miyu, the fact that her older brother is having sex with her friend is probably no different from seeing a performer on screen.

When I pulled out my cock, an incomparable amount of lewd fluid flowed out with what was happening during the act.

It didn't feel like she was cumming, but on the contrary, I just kept cumming so I maybe didn't realize that she was squirting.

"That's a lot. As expected of Onii-chan, right?"

Miyu ties the condom again and hands me the third condom.

My penis was still stiff.

"Yuka, what do you think? Have you reflected?"

Miyu opened only the head of the cardboard box and took out the panties that Yuka had been holding in her mouth.

The cardboard box is designed so that she can't see anyone can see except Miyu, who is sitting right next to her.

Yuka can't see me sitting completely naked in front of Yuka's butt.

"Uuguh... eeguh... ter... rible... even though it was... my first time..."

The first thing out of her mouth, Yuka didn't blame me.

If she had known that the rapist was me, she would have called out accordingly.

Apparently, through the cardboard box, she couldn't recognise the voice while we were having sex as mine.

If I say something here, Yuka might be saved to some extent.

There's no way Miyu would allow that.

It seems that Yuka has played with toys with Miyu and Haruka, but she has no experience with men.

She hadn't even dated a guy yet.

Such a beautiful body was defiled by a stranger.

Moreover, in Yuka's imagination, she thinks that her flowers have been cruelly trampled by a creepy otaku virgin.

"Here, this."

Miyu dropped two semen-filled condoms on the floor with a thud.

Miyu placed it in front of Yuka, who was crying as her virginity was scattered, fully swollen and covered in red love juice.

"Uu... uuUUuu...!!"

Ruthless.

It was truly the work of a demon.

Is the punishment just enough to balance the crime of secretly filming a friend's naked body and threatening to post it on social media?

I don't know about that anymore.

But it didn't matter.

I'm already willing to take on the hatred of both.

"Please tell me the ID and password of the account that posted the photo. Also, the password for Yuka's smartphone."

Miyu displays the social media timeline and password entry screen on her smartphone and Yuka's smartphone, and urges Yuka to do so.

Was the purpose to torture Yuka into revealing her password?

However, Yuka does not give up easily.

Because that social media account is Yuka's only weapon.

Because Yuka's only chance of winning is to threaten to release it, which still remains undisclosed and serves an a substantive backup for her.

"T-That's..."

I can't tell her.

If I can endure this torture, my turn will come eventually.

After already losing my virginity.

There's nothing to fear anymore.

"I see. So you don't want to say it."

However, that is until she hears Miyu's voice as sharp and cold as an icicle.

"W-wait! Wait, Miyu!"

"Then I'll have the third person deal with it."

"I said wait!! Hey Miyu!! Listen!! Don't go!!"

She closes the cardboard box once again.

Since Yuka no longer had anything in her mouth, her voice was clearer and louder than before.

"Miyu!! I'll say it!! I'll say it so!! Stop it already!! Don't insert strangers into meeeee!!"

"Onii-chan, do it."

Miyu completely ignored Yuka's voice.

Even if the person's heart is broken, she's still destroying the root of it.

"Are you sure? Yuka, she said she'd give you the password though..."

"There's no way she can get away with this. She's a liar. She might be hiding the photos in other places as well."

The reason why Miyu is so thorough is because Yuka's weapon is electronic data.

If she doesn't thoroughly find out how much she has, there wouldn't be any meaning.

That's why it won't end without any cost.

She intends to push Yuka to the bottom until she no longer feels like disobeying her again.

"No, no!! I don't want it anymore! Stop it... please help me already...!!"

It's different than before she opened the box.

Yuka's voice, which was just screaming, was now filled with various emotions.

The voice of despair shakes my eardrums.

Bikun, bikun, my penis collects blood.

"Why am I... in this situation..."

Even if it was Miyu's orders, it was abnormal for me to get an erection in such a state.

Or rather, just as women gets wet just by getting excited, is my brain going out of control due to this abnormal state of tension and my erection becoming uncontrollable?

However, this feeling of simmering testicles is definitely a sign of high sexual desire.

In front of me is a female restrained with her genitals exposed.

Even if it's laid out on the table, I can't afford to miss this great opportunity to produce offspring as a male.

That instinct is pushing me to insert myself.

"Yuka... I'll finish it right away..."

I put on a condom for the third time and press it against Yuka's slit.

Her twitching vagina meat was inviting me with excitement.

"No no! Hey, please! Please don't do this anymore...!"

Yuka begs for forgiveness inside the cardboard box.

I ignored all of that and inserted my penis into Yuka's vagina.

"GyaaaaaAAAAAAAaaAHHH!! I don't want tHIS ANYMOREAAAAAAaaAAAAAHHH!"

A scream reverberating in two stages, both in the room and in the cardboard box.

Miyu seems uninterested as she flaps the remaining two condoms and watches Yuka and I have sex.

This long night had not yet come to an end.

(T/N: Despite sounding like unintelligible garbage, 'NnneeeEHe-!! Nneh, nnnheeehee!!' actually spells a muffled version of the Japanese word やめて (yamete), meaning 'Stop it' which ends up looking like (nhh-ehh-heh).)
