My Little Sister Is the Best F*p Material - Volume 3 Chapter 7: Little Sister's Sexy Temptation Hellish Ejaculation Management

Volume 3 Chapter 07: Little Sister’s Sexy Temptation, Hellish Ejaculation Management – “No Ejaculation for You, Onii-chan” Part 4

I walked, cutting through the wind, my eyes following the evenly spaced street trees. It was as if I were a different person.

If this were a few months ago, I would have been a creepy otaku, just acting tough. But with Miyu choosing my clothes for me, introducing me to a good beauty salon, and starting muscle training, I had noticed that the world had changed.

I didn’t care about other people’s stares, and I wasn’t nervous when someone talked to me. I used to feel ashamed of my existence just by talking to people, because my self-esteem was extremely low. But as each of those issues was improved, I found that the everyday conversations that I had once thought were amazing when I watched other people were now easy for me, and I began to think, “I’m just a normal human being, after all.”

If it weren’t for the extraordinary sexual excitement I felt for my little sister, I really would have been a normal human being. But it’s her, so there’s nothing I can do about it.

My destination was the nearest station. Usually, I would use my bicycle, but it wasn’t that far to walk, either. Besides, since I was going to stay out tonight, I decided not to use my bicycle, as I would need a parking lot for it.

I took a different route, away from the familiar path. I had plenty of time, anyway. Exercising would also help dissipate my sexual desire.

On holidays, I had spent most of my time on my otaku hobbies, often staying indoors playing games or on the internet. So, being told to play outside for two whole days was a bit of a problem. However, I wasn’t completely without things to do. I had to make progress on the app that Suzuhara had recommended to me, and I also had to level up my online game character. So, I planned to spend the night at an internet cafe. Until then, I would go to an electronics store and look at computer parts for the first time in a while.

There was a large avenue where apartment buildings began to increase in number, between the residential area and the station. A large river flowed through the middle of it, and I could see some children waiting for their bikes on the bridge. Compared to the city, this region was full of wide-open nature, and there was a large park.

To put it nicely, but it was also a place where, if you didn’t go to the station, there was nothing else to do. In this area, couples and the elderly were relaxing on benches, and for me, who had no such relationships, it was like an unknown land, even though it was my hometown.

The scenery was nice. It made my chest feel light. The hardness of my penis, which had been half-erect since Miyu had stirred up my sexual desire, was gradually fading away.

“That’s a big apartment building.”

There was a high-rise apartment building that didn’t fit in with the scenery of the city. It wasn’t convenient to the station, but it was within walking distance of a supermarket, so it was an acceptable property. The land around here was cheap, but the people who lived in such an apartment building must be quite wealthy.

The entrance, with its double doors and automatic lock, was opened by a person who had come out of the building. Cots, cots, the thin-soled summer boots made a sound on the ground, and a woman with big breasts and a ponytail appeared. I thought a rich lady would come out, but it was a sexy-looking older woman.

“── Yamamoto-san!?

“Ara. It’s Sotomichi-kun.”

I was surprised to see a familiar face. I had never met her on the way to school, even though we went home in the same direction, probably because she lived in such a place.

“Oh, good morning.”

“Good morning. It’s quite a coincidence for me to meet you so early in the morning.”

Yamamoto-san naturally lined up next to me. She looked very happy. I must be quite popular with her. As I came to know the other side of Yamamoto-san, who was kind to everyone, I could see the difference between a smile of goodwill and a smile of politeness.

“Sotomichi-kun, you reallylook good. You’re much cooler than before.”

“U-uh? Thanks.”

Until now, it had been embarrassing for me to be seen in my private clothes by someone else, but thanks to the proper outfit I was wearing, I was able to talk to Yamamoto-san without being nervous. I had to thank Miyu for forcing me to improve my appearance, even if she was angry with me now.

“Sotomichi-kun, are you going out?”

“I’m wandering around because Miyu kicked me out.”

“Ara ara. Are you guys fighting?”

“I don’t know, but I’m being scolded.”

It wasn’t quite a fight.

“So, you’re free now?”

“Yeah.”

“I see~”

Yamamoto-san was looking at me with a smirk. When I reacted by tilting my head, wondering what was going on, Yamamoto-san came close enough to bump her arm against mine and spoke to me in a low voice.

“Then, would you like to go to a place where we can be alone for a little while?”

My lower body reacted with a twitch, filled with expectation and excitement, at the question, which was clearly intended to be lewd. It wasn’t something that could be proposed so casually, especially by a cute girl like Yamamoto-san.

“I’m sorry, but I can’t today.”

“Huh? Why? Is there something special about today that you can’t?”

Yamamoto-san was surprised by my answer, her eyes wide. I had to explain it well, or she would misunderstand again, thinking that I wasn’t interested in her. However, I didn’t have the confidence to explain the current situation, where I was forced to abstain from ejaculating by my sister, in a roundabout way.

“I’m wandering around now, but I have plans to meet someone. So, I don’t have time for sex.”

“But you just said you were free. Even if you have plans, don’t you have a little time?”

“If it’s just a little, I won’t have enough time.”

“I mean, I know I’ve only been teasing you, but next time I’ll go all out.”

Yamamoto-san was strangely persistent. Why did she want to have sex with me so badly? Especially when I wasn’t allowed to ejaculate.

If I were forced to have sex with her again, Yamamoto-san would surely go all out and try to make me ejaculate. Then, I wouldn’t be able to keep my promise to Miyu. Even if it was an accident, it was my responsibility that such a situation had occurred. I also wanted to have sex, and I was happy to have met Yamamoto-san, but I had to retreat in this situation.

“Wait! Let me say one thing at least!”

I, who was trying to leave, was stopped by Yamamoto-san, who hugged me. If someone had seen us, they would have thought we were a couple having a lovers’ quarrel. And on top of that, it was a bizarre situation where a man like me, who was not very impressive, was dumping such a beautiful girl.

“What is it?”

“I-I’ve never been turned down when I’ve asked someone to have sex with me in my life.”

I was sorry. There was nothing else I could think of.

“I’m sorry. Maybe next time.”

“Uuu… What’s more important to you than me…?”

I understood. Any man who turned down such a cute girl was crazy. But there was nothing more important to me than my sister.

“Anyway, let’s walk.”

I gently pulled Yamamoto-san, who was still hugging me, away. Yamamoto-san’s voluptuous body was bad for my penis, which was already aroused.

“I want to ask you something, though. Do you really need to have sex with me?”

“Need… what do you mean?”

“I mean, don’t you think there are plenty of other guys who aren’t conscious of you just like me?”

I thought that a beauty like Yamamoto-san would not have sex with me for such a trivial reason. When I asked her, Yamamoto-san blinked her big eyes, as if to say, “What are you talking about?”

“No, there aren’t. Do you think there’s even one?”

“I… thought so… but…”

So that’s the level. Just as I was surprised that such a beautiful girl as Yamamoto-san had talked to me, it was something that could not happen to Yamamoto-san, that she was not seen as a woman.

“Even if I were the only one who turned you down, wouldn’t it be better for you to not have sex with me? Your body isn’t that cheap, is it?”

“I can’t do it with other boys. I can’t… unless it’s with Sotomichi-kun… Oh, did you think I might be doing the same thing with other boys? ‘m not. Usually, I only do it with the person I’m dating.”

Yamamoto-san quickly added a supplement. I didn’t think she was making high demands of me, but Yamamoto-san’s male experience wasn’t something that interested me much. I didn’t think she was doing it with just anyone, but I thought that was the kind of standard she had to have to choose me.

“I don’t even do that with the person I’m dating, though…”

“You don’t? I thought…”

I hesitated to finish the sentence, but then I decided to speak it out, as Yamamoto-san was looking at me with her eyes, asking me to tell her.

“That Yamamoto-san was a pervert.”

“I admit that I had such a desire.”

Exposing herself at school, doing a paizuri and letting me ejaculate inside her cleavage… She seemed to admit that she wanted to try those things. But that meant she couldn’t do it with her ex-boyfriends, right? Well, it was normal for a man to be put off if a girl asked him to do such things.

Could it be that Yamamoto-san liked me because she had noticed the perverted feelings I had for my sister? If that was the reason, I could understand why I was chosen.

“By the way, where are you going, Yamamoto-san?”

If I continued like this, I might end up exposing my relationship with Miyu, so I decided to change the subject. Yamamoto-san was walking with me as if it were natural, but she must have had some plans and left the house.

“I’m going to pick up my younger brothers. My parents are going on a trip this weekend, so they asked me to take care of them at my house.”

“So your family is also a neglectful one.”

Yamamoto-san could probably do housework as well as me, or even better, but leaving the children alone at home and going on a trip… Were her parents like my parents, a couple who got along well?

“Yamamoto-san’s younger brothers huh… I bet they’re good-looking.”

With such a mature and beautiful appearance as Yamamoto-san’s, they must be tall and handsome.

“Not at all. They’re short and look like girls.”

Yamamoto-san stroked the air with her palm facing down, using the mountain of her chest, created by her shoulder bag, as a reference for their height.

“That’s why I often make them dress up as girls and play with them.”

“What a terrible sister…”

Yamamoto-san, who was an angel at school, treating everyone kindly, was probably taking over the world at home. If I were living with such an excellent and beautiful older sister, I wouldn’t be able to resist her. I was in this state even with my little sister.

“Wait a minute… Are your younger brothers not living with you?”

What did she mean by saying she was going to pick them up at home to take care of them? Family members were supposed to live together, weren’t they? Unless her parents were divorced or separated, which didn’t seem to be the case, since they were going on a trip together, and it was strange to use the expression “take care of” for her own brothers.

“Umm… well, that is…! Er… My brothers are staying at a relative’s house… and they’re coming back now that my parents are going on a trip…”

“If your parents are going on a trip, wouldn’t it be easier for you and safer for your brothers if they stayed at a relative’s house?”

I pointed out the obvious contradiction, and Yamamoto-san, who gave up early, stopped trying to argue and tried to cover it up with a smile, saying, “Ehehe.” It seemed that Yamamoto-san was not good at lying.

“It’s rare for a high school student to live alone.”

In other words, that was the case.

“Please don’t tell anyone. It’s a secret from everyone but my family.”

Yamamoto-san was living alone in one of the rooms in that apartment building. She hadn’t even told her boyfriend about it, other than her family. I would have thought that a girl who loved sex so much would actively invite men to her place when she started living alone, but it seemed that there was another side of Yamamoto-san that I didn’t know about.

As I was thinking about it, Yamamoto-san’s phone rang. The display showed “A-kun.” Was it her younger brother? They seemed to get along well.

[Hey, you! How long do you intend to make me wait, you pig!]

The first words were full of momentum. The tone was masculine, but the voice was childish.

“Okay, okay, Onee-chan will be there soon. Just wait a little longer, okay?”

[If you keep walking like a cow, I’ll make you buy me ice cream!]

“Don’t get so angry. I’ll be good and listen to what you say, Mi-kun.”

[Shut up! If you don’t come in three seconds, it’ll be two ice creams!]

The call was cut off with a “Butsu.” Yamamoto-san was smiling, her hand on her cheek.

“He’s quite different from the image I had…”

“The younger one is a bit of a rascal. He hits me when I try to kiss him on the cheek.”

“You should discipline him properly.”

Such a beautiful woman being hit… He wouldn’t become a decent man.

“Discipline him? That’s not… As a big sister, I should embrace my little brother with unconditional love.”

Yamamoto-san said that, then hugged her own abundant breasts with both arms.

“And suffocate him with my breasts until he passes out.”

“That’s too much…”

I take it back. It was clearly Yamamoto-san’s fault that he became a rascal.

“Won’t he rebel even more if you do that during his puberty?”

The younger brother sounded like an elementary school student. He was at an age when he would reject excessive physical contact from his older sister, no matter how beautiful she was. Yamamoto-san thought about it for a moment, then returned to her dreamy expression.

“But it’s cuter when he’s rebellious.”

Oh, she’s a bad sister.

“After he becomes obedient, I dress him up in girl’s clothes, and then he comes to me, saying, ‘Big sister, I’ll listen to you, so let’s get along.’ Hehehe. He was like that on the phone, but we get along just fine.”

“I see…”

Her love was too distorted. But I couldn’t say anything, either.

Just then, Yamamoto-san’s phone rang again.

“Oh, I’m really loved. Sorry, Sotomichi-kun. My brothers are calling for me, so I’ll go ahead.”

“Okay. Be careful of cars.”

“Thanks. Let’s talk slowly just the two of us next time.”

Yamamoto-san waved at me with a cheerful face, then ran off, answering the call that had just come in. Hearing Yamamoto-san’s words, repeated with such excitement, “See you later” and “Next time,” I almost believed that Yamamoto-san was seriously attracted to me as a member of the opposite sex.

How could I confirm that? I was thinking about it in the back of my mind as I walked aimlessly towards the station. Then, I walked around the town, consulting my wallet about my unreasonable wishes, such as expanding the memory of my computer for my game.

The reservation for the net cafe was from the evening. Until then, I spent my time killing it at an open cafe, securing power, playing the app, and going from game center to bookstore.

“Is this for the night plan? Was it the free-time pack until noon tomorrow?”

“Yes. That’s right.”

I didn’t have any plans for tomorrow, so I would take plenty of time. Staying at a net cafe, even if it was Miyu’s command, was quite a blow. How many hours would I have to work during summer vacation?

I was given a card key and went to the private room. This net cafe was one rank higher than the one I had come to with Sachiko before. First, I started reading manga. There were several works that I had stopped reading in the middle, so if I finished reading them here, I could consider that I had made up for the cost of the number of books.

The spines of the books lined up on the bookshelf were nice. Whenever I saw them, I felt excited. It was getting late, so I was starting to get horny. But I had to spend the night without ejaculating.

“Oh, oh. Isn’t that Miyu’s brother?”

That voice came from the corner of the bookshelf. There was no doubt that it was the voice of that worthless woman, with its annoying tone.

“It’s you, Yuka.. You really do like ambushing me on net-cafes, huh?”

“I love the atmosphere here. The air is so lewd, isn’t it?”

“You really want to make this net cafe a place for erotic things, don’t you?”

I couldn’t say that, having actually done it myself.

“Mufufu. Don’t say that. You’re overflowing with eros, Onii-san.”

Saying that, Yuka looked at my bulging crotch.

This was bad. When I heard Yuka’s voice, I couldn’t help but remember Miyu’s punishment.

“There are deep circumstances behind this.”

“Hmm. What kind of circumstances? Are you a lolicon, by any chance?” Oh! That’s common knowledge, isn’t it? Pukuku.”

Damn this girl… I couldn’t imagine getting along with her at all.

“Well, it’s okay. If it’s yours, Yuka-chan might not mind helping you out.”

Yuka came closer, pushing her finger against the zipper of my pants.

“Hey…”

Why were they so aggressive towards me?

“I’m in a really good mood right now. And it’s all thanks to you, Onii-chan. So I feel like I want to thank you a little.”

“Thanks to me?”

What was she talking about? I hadn’t done anything to thank me for… since the last time I met her at the family restaurant, we had only exchanged messages on our smartphones.

“Ahh──!!”

I had forgotten to tell Miyu about what had happened at the family restaurant. I had to tell her that Yuka was up to no good, but I had forgotten to do so. And Yuka had said it was thanks to me, hadn’t she? Maybe… no, it was certain. The reason Miyu was angry was that.

“Muhuhu. Do you remember now? You told me about Miyu’s weak point. I wonder why I didn’t notice such an easy thing.”

With a lewd smile on her face, Yuka took out her smartphone and showed me the display. It was a naked picture of a female student. There was no mistaking that this super-beautiful girl was Haruka.

“The other day, we had a health check. And there, I took this wonderful picture. Don’t you think it turned out well? Miyu’s benefactor..”

This was terrible. I had underestimated the situation too much. This was something that would make Miyu furious, and I was an accomplice to this crime.

“When I showed her this photo, Miyu’s face turned pale. It was so cute that I almost came… Haa…”

Yuka’s expression was in a state of ecstasy. She had already lost her sanity.

“Wait, you’ll die.”

“Huh? What are you talking about? I told Miyu that if she defied me, I would spread these photos. She’s my slave now. Tomorrow, I’m going to make her my toy all day.”

So that was the reason why Miyu had told me to leave the house for a day. She didn’t want to be seen being humiliated. She had done all that to keep me out.

“Why are you doing this? Don’t you like Miyu?”

“I did like her? I still love her very much. But for four years, Miyu never paid any attention to me. She never even smiled at me once. It’s all Miyu’s fault. Everything, everything.”

Her argument was absurd, but I couldn’t just dismiss it as completely wrong. Yuka was still a bad person, but it was also true that Miyu’s influence was too great.

“Huh? Huh? Are you not noticing something?”

“What do you mean?”

Yuka stared at me with wide-open eyes, peering into my pupils. To be honest, it was quite scary.

“Tomorrow, I’m going to make Miyu do a lot of embarrassing things. After I take those photos, who do you think will be the next slave?”

Yuka shook her smartphone at me. When it came to the people who would be troubled by having Miyu’s embarrassing photos as a hostage, there were only two people I could think of.

“Are you trying to make Haruka, besides Miyu, your slave as well using the pictures…?”

“No, no. Haruka won’t protect Miyu. She likes her as a love doll, not as a lover. Besides, Haruka is a really bad person. She’s the worst woman, compared to Miyu.”

Yuka’s voice was full of resentment. I could understand why she would hate her, having been subjected to such torture-like treatment. If Haruka wasn’t the one being threatened, then the only one left was…

“Me?”

“That’s right. Muhuhu. It seems you’re full of semen, Onii-san. You can give it to me.”

“Are you willing to go that far to become Miyu’s family?”

“Yes! There are a lot of girls who want to become Miyu’s step-sister. Your semen is in high demand.”

I had discovered a very unpleasant fact. Because Miyu was too popular, evil hands were reaching out to me, too.

“I won’t do anything bad to you. You’re my benefactor in many ways. First, you can look forward to receiving an erotic video of Miyu. Until then, don’t watch any erotic videos on the internet, okay?”

Yuka softly touched my penis through my pants, then smiled and headed for the cashier.

I had no idea that Miyu was being pushed so hard because of me. If it was my idea that had given Yuka that idea, it was no wonder that Miyu was angry. I wanted to stop Yuka by force, but if things got worse here, it would be impossible to recover. Even if I destroyed her smartphone, the data wouldn’t be erased.

How could I apologize to Miyu? And would she even forgive me?

I couldn’t just apologize by email or phone, so I concentrated on games and manga until Sunday at six o’clock, when I was allowed to go home, just waiting for time to pass. Even after leaving the net cafe, my mind was not calm. As the time of my return approached, my heart rate rose. The time that I had wanted to pass quickly was now telling me that I had only a few minutes left, tormenting my heart.

And then, finally, the moment came. At six o’clock, when I put my hand on the door of the entrance, the key was open. When I opened the door, there was… Miyu, as usual, waiting for me with her hands folded in front of her.

“Welcome back, Onii-chan.”

“Y-Yeah.”

It was normal. Too normal. That was abnormal. Yuka was supposed to come to the house and give her unreasonable orders, but I couldn’t feel any anger or sadness from Miyu.

“Right away, Onii-chan. I’d like to give you the second command.”

Miyu instructed me to go upstairs, then climbed the stairs to the second floor, and I followed her.

“Onii-chan, you like onaholes, don’t you?”

“Well, I don’t dislike them, I mean… rather, I like them…”

“That’s right. You like them, Onii-chan.”

Miyu suddenly stopped.

It was in front of my room.

“I wanted to ask you to develop an onahole, Onii-chan.”

Miyu picked up a small box that was placed in front of my room and showed it to me.

It was a condom, considered the thinnest in the industry. It was a high-end skin, with five pieces inside.

“You’ll listen to the command, won’t you, Onii-chan?”

Without realizing it, the human-like shine had disappeared from Miyu’s eyes. Her eyes were dark, almost black, and her hand rubbed my crotch. My crotch was swollen, as if to show the amount of semen I had accumulated.

“Ah, ah…”

At that moment, I finally understood the meaning of the danger signal my brain had sent me the morning before.

When Miyu opened the door to my room, what was inside was a large cardboard box. One side of it was cut out, and only the butt was sticking out. It was in a supine position, with thighs attached. It was like a large onahole for normal position insertion, but considering its size and texture, it could only be a real human being.

“Hey, Miyu…”

“It’s too late to say no now. Will you listen to my command?”

Miyu pushed the box of condoms against my chest and glared at me with cold eyes.

“There are five condoms in it. All you have to do is fill that onahole with semen. Then you’ll be free. It’s an easy job. Good job.”

Her voice was extremely cold and flat.

I had no right to refuse. I had to obey any command. I had thought there would be a limit, but this sister of mine had crossed that line. Today was the last day I would be a decent human being.

It was a command for rape, which could not be excused.
