My Little Sister Is the Best F*p Material - Volume 3 Chapter 8: Little Sister's Sexy Temptation Hellish Ejaculation Management

Volume 3 Chapter 8: Little Sister’s Sexy Temptation, Hellish Ejaculation Management “Rape Her, Onii-chan” Part 1

It was a scene I would have never imagined.

My room, from which all light was blocked out by the window. A large cardboard box placed there. Only a woman’s butt was exposed from the box, lying on its back.

Miyu called it an onahole. And she had ordered me to fill the condom with semen using the realistic female genitalia.

One was a slave, the other a tool. What I was about to do was to insert my penis into Yuka’s vaginal hole, without her permission, and ejaculate.

“Miyu… this is definitely… a crime…”

It was beyond the scope of punishment. If Yuka wanted to, I could be sued and arrested.

“So what?”

Miyu guided me in front of Yuka, who had become an onahole, without hesitation.

The body, which protruded from below the navel to the sitting bones, had its legs back inside the cardboard box, with its thighs spread, and its knees and feet were stored inside. The cardboard box was enlarged with craftsmanship, but it was not possible to fit it without tying it up with the knees extended. She must have been forced into a very tight position.

When I touched the smooth curve of the buttocks, I could feel a human-like temperature. It was real. A real human being had been made into an onahole.

“This is… Yuka… right?”

There was no reaction when I pinched the flesh. Was she asleep? If she had been given a sleeping pill, it might be better to finish it while she was sleeping, for Yuka’s sake.

Either way, it was not something a person with normal nerves would do. It was crazy. Why were Yuka and Miyu so twisted?

“If this becomes a police matter, I’ll be expelled. Miyu will also be suspended. And Yuka will be traumatized for life if she is raped. No one will be happy.”

I thought I was making a reasonable argument. There was nothing wrong with my words. I was absolutely sure that I was right, but…

“That’s only if you’re reported. Besides, Yuka was the one who committed the crime first. I’m just handling it within the family. That’s kindness, isn’t it?”

Miyu came close to me and looked at me. I felt like I was being grabbed by the collar by a yakuza.

“Yuka will repent, I will stop being a naughty girl, and you will be able to repay your debt. Everyone benefits. Everyone is happy.”

Miyu’s words flowed into my ears. With each word, the burden on my heart disappeared.

I knew in my head that her argument was absurd, but somehow, I felt relieved as I listened to Miyu’s words. It was like I was under a hypnotic spell.

“Take off your clothes.”

Miyu’s command was absolute. I took off my shirt, lowered my pants, and, without being told, I took off my underwear, too.

I was completely naked in front of my sister, and my penis, which had been teased so much, was already erect. That alone was ridiculous, and yet I had to work hard to thrust my waist towards this onahole.

“Here. The first one.”

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

“Don’t ejaculate too easily.”

Miyu traced the curve of my frenulum with her fingertips.

“Fah… ah…”

A voice leaked out of me, overwhelmed by a thrilling sensation. It was the touch of Miyu’s hand, which usually refused to touch my penis. It was too much of a stimulus for me, who was about to explode.

“If you can’t help but ejaculate because it feels too good to rape a younger girl in front of your sister, I’ll forgive you.”

Miyu ran her index finger and middle finger over Yuka’s labia, and spread it open. A sticky liquid oozed out from the fleshy hole, and as Miyu’s finger left, it pulled a thread.

“I’m not… I’m just… I’ve been holding it in for two days now…”

I had been ejaculating several times a day, and then I was suddenly told to abstain from ejaculation. I couldn’t hold it in any longer. At least, I should be able to ejaculate the first time soon.

“I won’t accept that. Because it only looks like you’re trying to finish it quickly and ejaculate.”

In the end, that was Miyu’s opinion. Even if my true intention was to finish it quickly, she wanted me to not show it.

“For example, if you rape a girl while shouting that it feels good, Onii-chan, I might be able to accept it even if you ejaculate quickly.”

She was a devil.

This was a punishment for Yuka, and also a punishment for me.

What was most important to this sister of mine was sincerity. If I truly wanted to apologize from the bottom of my heart, there was nothing I couldn’t do, she was implying.

“Let’s get started.”

Miyu pressed the head of my penis with her finger, and sank it into Yuka’s cleft.

I had no choice but to insert it. At least, while Yuka was still asleep. I had to finish it as quickly as possible, without stimulating her too much.

The glans, which had entered the vagina halfway, was gradually enveloped by Yuka’s body temperature. If I inserted it so that the corona rubbed against the vaginal wall, there was no doubt that the rape would be complete.

I had only met Yuka a few times. We were not in a relationship where we could have sex. She had said that she would bear my child if we became family, but it was foolish to take her words, which had been said on the spur of the moment, seriously.

If I sank my waist a little more, it would go in. I couldn’t make any excuses, like “I was ordered by Miyu.” I was going to rape Yuka.

“N-nuh…?”

Yuka’s buttocks muscles twitched. I was so surprised that I jumped up, and that movement stimulated Yuka’s vagina just before it entered.

“N… nnn… nnnn!! Nnnuuunnn!!”

A muffled scream came from inside the cardboard box. Yuka was screaming. She had realized that she was about to be raped, and was desperately resisting.

“Ara ara. I even left her alone for five hours. She should have been sleeping.”

Miyu slapped Yuka’s butt hard. Just that sound made Yuka, who was restrained inside the cardboard box, scream in agony, as if she had been stabbed with a knife.

“M-Miyu! What have you told Yuka…?”

“I asked her to help me with someone I know who wants to lose his virginity.”

Miyu had lied to Yuka. Yuka thought she was going to be raped by unknown men, not by me.

It was the worst lie possible. Yuka knew what I looked like before Miyu changed me, and that Miyu was recruiting girls for the purpose of sex with me. To Yuka, I was the same kind of creature as a geeky otaku.

What image would Yuka have of a friend of a virgin otaku?  I didn’t have to think about it. Now, in this age of meet-ups, my acquaintances were not limited to my school friends. Yuka was imagining that she would be raped one after another by such men. (T/N: Take note, there are 5 condoms. Miyu most likely informed Yuka that she will be done by 5 unknown men, which is now 5 otakus, since she thought it was Miyu’s big brother and his friends.)

“Nnnnhehe!! Nhe, nnnn… nhehehe!!”

Yuka couldn’t speak properly because her mouth was covered, but I could tell that she was screaming, “Stop it!! Stop it!!” in this desperate situation. She was begging me not to rape her.

I could hear the sound of my heart beating, “Dokun, dokun.” I had to rape this girl, who was so reluctant.

“Haa… gah…”

I couldn’t catch my breath. I was already out of breath, even though I hadn’t moved yet, because I was too tense.

“Onii-chan, this.”

Miyu, who was getting impatient with me for not trying to insert it, showed me the screen of her smartphone. It was a timeline of an SNS. It was a site where you could send messages anonymously to a large number of unspecified people.

“What…?!”

The moment I saw that screen, I was horrified.

“Yes. It’s already been posted online.”

Miyu scrolled the screen with her finger, and one after another, images were displayed. One of them was the hidden photo of Haruka that Yuka had shown me at the net cafe. However, the reason why Miyu was angry was not limited to that.

“What… even Miyu…?”

Miyu’s naked body was also uploaded. It was a photo of her in the middle of taking off her bra for chest circumference measurement. Yuka had posted that photo, which clearly showed Miyu’s most complex part, on SNS.

“It’s posted on a newly created private account, so fortunately, no one has seen it yet. But in this day and age, you never know how it will be salvaged. This woman has left scars on my body and Haruka’s. So I’ll make her lose the same thing.”

The punishment that Miyu imposed on Yuka. It was to make Yuka lose her virginity by group rape, as if it were Yuka’s imaginary punishment.

“Yuka, you said it many times, didn’t you? That you can make me obey thanks to Onii-chan. Hey, Onii-chan. Why aren’t you raping her yet?”

This was the sin of both me and Yuka.

I had to settle it. Together with the two of us.

“Yuka, I’m sorry…”

“Nnnnnn!! Nnnuuunnn!!”

I grabbed Yuka’s butt tightly, which was resisting even more fiercely. I thrust my waist forward, and my penis entered Yuka’s vagina, “Nup, nup.”

“Nnnneeehe!! Nnnggyyaaaahhhhh!!”

Yuka, who was struggling, was not able to move as much as the momentum. Instead, the contracting vaginal walls, which were trying to narrow the entrance of the vagina to prevent the intrusion of my penis, were stimulating my penis exquisitely.

“Naaaahhhhh!! Aaaahhhh!! Nngnngaaaahhhh!!”

My penis was entering Yuka’s vagina, pushing out the love juices.

When half of my penis was inserted, I still thrust my waist forward.

“Ahh… ahh…”

The female genital hole that I had tasted for the first time in a long time was narrow and soft. A sense of guilt and a sense of pleasure crept up on me, and my erect penis, which had reached the depths, gouged Yuka’s cervix.

“Nnnngggyaaaahhhh!! Nnngyaaaahhhhhhh!!”

It was a scream that sounded as if her throat was being scraped. It was a scream that sounded as if Yuka was spitting blood in this cardboard box, with all her might. The sound that leaked out of the sealed space was clearly audible to me, who was right next to it.

It was a scream of resistance against rape. It was a sob for the loss of her purity. It was a regret that had stopped, knowing the weight of the sin she had committed. All of it was reaching my ears in real time. My heart was getting darker and darker, to the point that I could hardly breathe. Still, I kept thrusting my waist.

Pan, pan, pan, pan. Jubu, jubu, guchu, guchu…!

With each slap of my waist, Yuka screamed. I was raping this girl, who couldn’t even make a judgment about good or bad, without even getting angry or scolding her. It was an act that no human being should do. Yuka, who had lost her virginity, was still begging for salvation, saying, “Stop it!! Stop it!!”

“Yuka, I’m sorry… Yuka… ahh… it feels good… it feels good…”

I had been teased by Miyu, and I had been forbidden to masturbate. The feeling of twisting my rock-hard penis into this narrow meat hole was irresistible. No matter how much Yuka resisted, it only made the grip stronger. The pressure that rubbed my penis was getting just right.

“Ngaaaahhhh!! Nnnuuunnn!! Nn… Uggguuuu!!!”

The sound of the floor being hit, “Dosun, dosun.” Yuka was banging her head to show that she was inside. I already knew that she was a real human being, but…

The sound of Yuka banging her head did not become a loud impact sound, as if there was a cushion on her head. Still, the movement of her lower body, which was tightly restrained, told the intensity of her resistance.

My penis, which was filled with blood and was swollen, was no longer the weak penis it had been before. It had definitely increased in size with the repeated masturbation with Miyu. I was forcing it into the vagina of this small girl. It couldn’t be anything but good.

“Ahh… I’m gonna cum… I’m gonna cum…”

The strokes of my waist, which were moving vigorously.

The honey that overflowed from the meat pot burst.

“Nnnnnn!! Nnngyaaaahhhh!! Gyagyaaaahhhhh!!”

“I’m gonna cum… I’m gonna cum… I’m gonna cum… Ahh, aaaahhh!!”

Dpyururur, dopun, byurur, dop, dop… The semen that had been accumulated for two days was ejaculated inside Yuka’s vagina.

With each ejaculation, my penis swelled, and Yuka’s narrow vagina was stretched even further. Yuka must have understood that she had been ejaculated inside her vagina.

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

“Ah…”

I had done it. I had finally done it. I had raped a girl who was still a child, even in my eyes. I had broken a law that I should never have ignored.

“Good job, Onii-chan. We’ve finished one, at least.”

The penis that I had pulled out of Yuka’s vagina was hanging a condom filled with a large amount of semen. Miyu pulled it off, closed her mouth, and handed me a new rubber.

“Ara.”

Miyu looked at the back and front of her hand after tying the condom. What was sticking to her fingertips was red. A slightly reddish transparent liquid was sticking to Miyu’s fingertips.

“I thought she had played with the toy a lot. Was there some left?”

The proof that Yuka’s hymen had been broken was all over the condom. When I looked closely, I could see that a red juice was dripping from Yuka’s labia.

I had raped Yuka’s virginity. I knew it was coming, but when I saw the real blood, I couldn’t help but feel a chill down my spine.

“Oh well. Next, do it.”

While I was multiplying my sense of guilt, Miyu dismissed the fact that Yuka’s hymen had been broken with “Oh well.” If it was my friend who was crying because her virginity had been taken away by a stranger. I wouldn’t say anything, being the perpetrator. I had ejaculated so much that the reservoir of semen in the condom was swelling, and I hated this sexual desire that was still hard.

“Ng… uuh… uuu…”

I could hear the sound of Yuka sniffling and groaning through the cardboard. My chest ached. How could I, who had done such a thing, pretend to be a victim?

Miyu and Yuka had both lost something important. I was the one who had taken it from both of them.

“Onii-chan, do you really regret it?”

“Of course…”

“Then, you can do it without me telling you, right?”

Miyu made me hold the condom tightly again.

I understood. Yuka was an extremely evil person who tried to expose Miyu and Haruka’s naked bodies to the world. She was a criminal who deserved to be punished.

I was, in a way, the perpetrator. I had accepted the job that no one wanted to do, as a punishment. The sense of guilt that I would carry with me for the rest of my life was the sin that I had to bear, and the compensation for my act.

“Uh… uuu…”

“Yuka, I’m sorry.”

“Uuuu… n, nnn!! N, n-!! Nnnnnuuuunnnnuuuunnn!! Nnnaaaahhhh!!”

I put on a rubber on my penis again and inserted it into Yuka’s vagina. There was still plenty of honey left in Yuka’s meat pot, which had been moistened by her defense instinct in this extreme state.

The screaming voice, which rose with each slap of my waist, and the body, which was struggling violently, both gradually became weaker. Yuka’s body had already lost a lot of energy by the time it was restrained in this cardboarThe voice, which had been screaming with all its might, changed to a crying voice. I could imagine her trying to resist this cruel fate, clenching her teeth.

She had done something that was not allowed. She was a bad girl who deserved to be punished, so she needed to be disciplined. I suppressed the thought of stopping my waist and apologizing, overwriting it with criticism of Yuka many times, and carried out my torment of Yuka.

“Ugh… uggh… uhh…”

Yuka, who had lost even the strength to cry, eventually stopped moving. In the quietening space, only my rough breath filled the void.

“Haa… haa… aah!!”

Gchu, gchu, gchu. The condom was scooping out Yuka’s honey, entangled with it. No matter how much we hated each other, we were in a state where we could have sex. However, no matter how wet it was, it didn’t feel like the body of a girl who was enjoying sex.

“Ah… aaaah…”

Still, as a man, I felt it. Whether or not she accepted me, if I rubbed my genitals against a wet vagina, the desire to ejaculate would rise. That was the instinct of a male, created to leave his seed.

As I vigorously moved my penis back and forth, the cervix and urethral orifice kissed each other repeatedly, as if I were forcibly stealing a kiss from a reluctant girl. Yuka, dripping with love juices like saliva, was alternately experiencing the spasms of her diaphragm brought on by despair and the stimulation of being stabbed in her vagina.

“Yuka, aah… Yuka… Yuka, I’m going to…!”

“Aaaah… uhh… aah! Uhhh… ggh… uhh… aah…”

I was about to ejaculate. I was going to ejaculate, on crying a girl who was resisting.

The strokes, which were getting bigger as I approached the finish, Yuka’s body already understood that it was an action to ejaculate.

“Aaaah, Yuka, haa… I’m going to cum…!!”

“Aaaah… nnnn… ggaaahh! Uhhh… ggg… uhh!”

The semen that was poured into Yuka’s vagina, through the condom, in the last struggle, was the same amount as the first time. Every time my muscles contracted with ejaculation, my field of vision flashed and went dark, and my brain and heart felt like they were overheating.

“Thank you. Take off the condom.”

Miyu remained calm throughout. To her, it was no different from watching actors on a screen having sex, as if her brother were having sex with a friend.

When I pulled out my penis, a lot of obscene liquid flowed out, compared to when I was having sex. Although I didn’t feel like I was coming, it seemed that I might have been squirting.

“Wow, that’s a lot. As expected of Onii-chan, huh?”

Miyu tied the mouth of the condom again and handed me the third condom. My penis was still hard.

“Yuka, how is it? Do you repent?”

Miyu opened only the head part of the cardboard box and took out the panties and bite cloth that Yuka was biting with her mouth.

The cardboard box was designed so that only Miyu, who was sitting sideways, could see. The naked me, sitting in front of Yuka’s butt, could not be confirmed by Yuka.

“Ugh… egh… h… horrible… uhh… it was my first time…”

Yuka did not blame me right away, as soon as her mouth was free. If she knew that I was the perpetrator, she would have said something appropriate.

It seemed that Yuka couldn’t tell that the voice during sex was mine, through the cardboard box. If I spoke to her now, it might be a little relief for Yuka, but Miyu would never allow it.

Yuka seemed to have played with toys with Miyu and Haruka, but she had no male experience. She had never even dated a man. Her beautiful body had been defiled by a stranger. And in Yuka’s imagination, it was a virgin otaku. She must have thought that her flower had been ruthlessly trampled.

“Here, this.”

What Miyu dropped on the floor with a thud was two condoms filled with semen. Miyu placed the red, semen-covered condoms, which were swollen with plenty of semen, in front of Yuka, who was crying, having lost her virginity.

“Ugh… uhhhh…!!”

It was cruel. It was a deed worthy of a demon.

Was this punishment, threatening to post her friend’s naked photos on SNS, enough for the crime? I didn’t know anymore. But it didn’t matter. I was ready to bear both hatreds.

“Tell me the ID and password of the account that posted the photos. Also, the password for Yuka’s smartphone.”

Miyu displayed the SNS timeline and the smartphone password input screen on her own smartphone and Yuka’s smartphone, respectively, and urged Yuka to tell her.

The purpose was to torture Yuka and make her confess the password. But Yuka didn’t talk easily. Because that SNS account was the only weapon Yuka had. It was a backup that was still in private, and threatening to release it was Yuka’s only winning move.

“T-Thats…”

She couldn’t tell. If she endured this torment, her turn would come eventually. Her virginity was already lost. There was nothing to be afraid of anymore.

“I see. You won’t tell me.”

But that was only until Miyu glared at her with her piercing eyes, like an ice pillar.

“Wait! Wait!! Miyu!!”

“Then, the third one. I’ll have you process it.”

“Wait! Wait!! Listen, Miyu!! Don’t go!!”

The cardboard box was closed again. The voice that leaked out was clearer than before, as the thing that had been stuffed in Yuka’s mouth was gone.

“Miyu!! I’ll tell you!! I’ll tell you!! Stop!! Don’t let unknown people insert it inside me!!!”

“Onii-chan, do it.”

Miyu completely ignored Yuka’s voice. Even though Yuka’s heart was broken, she was trying to destroy her very foundation.

“Is it okay? Yuka said she would tell you the password…”

“There’s no way this will end with this. That girl is a liar. She might have hidden the photos in other places, too.”

Miyu was being thorough because Yuka’s weapon was electronic data. It was meaningless unless she thoroughly made her confess where she had copied it. So she wouldn’t let her off easily. She intended to push Yuka to the bottom of the bottom, so that she would never have the will to defy her again.

“I don’t want to! I don’t want to anymore!! Help me…!! Please help me…”

It was different from before she opened the box. Various emotions were layered on top of Yuka’s voice, which had only been screaming. The sound of despair that shook my eardrums, my penis gathered blood, twitching.

“Why am I… in this situation…”

Even if it was Miyu’s command, it was abnormal to get an erection in this state. Or maybe, just as a woman becomes wet with excitement, my brain nerves were running wild in this abnormal state of tension, and my erection wouldn’t go down. But this sensation of my testicles boiling was undoubtedly a surge of sexual desire.

In front of me was a female, bound, with her genitalia exposed. Even if it was a ready-made meal, I couldn’t miss this opportunity to leave my seed as a male. Such an instinct was urging me to insert it.

“Yuka… I’ll finish it as early as I can.”

I put on the condom for the third time and pressed it against Yuka’s cleft.

The twitching vaginal flesh was inviting me in a lewd way.

“I don’t want to! Please, please! Don’t do this anymore!! Please don’t make me do it with someone I don’t know!!!”

Yuka, who was begging for forgiveness in the cardboard box, I ignored everything. I thrust my penis into Yuka’s vagina, zub, ignoring her.

“Gyaaaahhhhhh!!! No moreeeeeee!”

The scream echoed in two stages, in the room and in the cardboard box. Miyu seemed uninterested as she waved the remaining two condoms, watching the sex between Yuka and me. This long night didn’t seem to be ending anytime soon.
