My Little Sister Is the Best F*p Material - Volume 1 Chapter 04: My Little Sister's Affection Rating

Volume 1 Chapter 04: My Little Sister’s Affection Rating

The button on my uniform came off.

When I took off my school bag, the strap got caught on the sleeve of my blazer, and I tried to pull it out forcefully, but the thread snapped.

This is going to be a hassle. It’s still a bit weird to wear a uniform that’s asymmetrical for over a year. The sleeve opening flaps around and hits my hand.

(Come to think of it, Miyu is good at sewing.)

There was a time when Miyu was obsessed with making her own clothes. So, sewing on a button should be no problem for her. After changing, I knocked on Miyu’s door, holding the button and the blazer.

“Miyu, can I ask you something?”

“Sure, come in,” came the voice from the other side of the door. I opened the door and saw Miyu sitting at her desk, who turned and invited me in.

“Sorry to interrupt your studies. This button came off. Can you sew it back on for me?”

“Just sewing on a button? I can do that quickly.”

Miyu took out her sewing kit from the drawer and threaded the needle with practiced ease. There was also a sewing machine in the corner of the room, so she might still be pursuing her hobby.

Miyu’s profile, sewing with a calm expression. Her long eyelashes framed her large eyes, which were fixed on the spot where the button needed to be sewn.

With just a blink of her eyes, a feminine aura wafted around her. She seemed to have a gentler expression than usual. She was threading the needle skillfully, almost smiling.

She was so cute. Just watching her sew the button made my heart race. It was as if I were in love with my little sister.

Even though I had released all that desire, Miyu continued to treat me normally after we were done. On the other hand, considering the fact that our relationship was particularly lewd, it meant that my sweet little sister would drink my semen if I asked her to.

“There you go, I’m done.”

“Already? Thanks.”

“No problem.”

I was so lost in admiration that I didn’t realize she was finished.

“So, are you going to do that too?”

“That… Oh, this…!”

I hadn’t noticed that my crotch had become rock hard.

I should be getting my sexual needs taken care of by Miyu, but I get so excited that it’s an endless loop. However, she seems ready to let me finish, so it would be a shame to refuse this offer.

“Then… after you’re done studying…”

“Okay. It won’t take more than a few minutes, so I’ll come to your room when I’m done.”

“Alright. I’ll be waiting.”

I left Miyu’s room, my heart still pounding. If we keep having these kinds of interactions, we’ll never be able to go back to being a normal brother and sister. Even if Miyu likes me and we’re in love, it’s still a bit much. For now, all she does is help me with my ejaculation.

Could it be that I’m just dense? Like in an erotic game, the heroine’s affection rating might be high enough, but I keep choosing the wrong options, preventing the story from progressing. In other words, maybe it’s time to confirm Miyu’s feelings.

The problem is, how do I confirm her feelings? Based on our past interactions, it’s easy to imagine that her true feelings won’t come out just from talking.

Then, this is a chance. A rare, perfect opportunity. I should take advantage of Miyu’s good mood now.

“—Onii-chan? Are you ready?”

“Yeah, I’ve been waiting.”

I took off my lower garments and sat on the edge of the bed, waiting for Miyu. My penis was fully erect, pointing towards the sky. Miyu, who had sensed something different about my mood, entered the room with an awkward gait.

“Are you going to finish like that?”

“No, I’ll stand up today. Miyu, kneel down over there.”

“Haa.”

Miyu was still on her guard, but she followed my instructions. I thought it might have been a bit too much, but it’s important to hint at what I want to say. Miyu might have already guessed my intentions. She might be thinking, “He really wants me to do it, doesn’t he?” at this very moment.

And as I was thinking that, my senses became numb, and eventually, Miyu’s psychology would change to, “Maybe I should do it today.” Then, the answer I’ve been searching for might appear after the act.

“The atmosphere is a bit different today.”

“Did you notice? Actually, I have something important to ask you.”

“What is it?”

Miyu tilted her head adorably.

My penis reacted with a twitch to her cuteness.

Now, it’s showtime. Calmly. Smoothly. As my desire dictates.

“I was wondering if you could give me a blowjob.”

As I showed her my swollen spear and told her seriously, Miyu narrowed her eyes and said, “I say no.”

There was no hesitation. I thought that this sister of mine liked me and was just too shy to take the first step, so I thought she would reluctantly agree if I pushed her.

“Is it absolutely out of the question?”

“Yes.”

“I don’t need you to suck it, just a lick would be enough.”

“It’s the same thing to me.”

Her defenses were impenetrable. I couldn’t see any gaps to exploit. Could it be that this sister of mine doesn’t actually like me?

“You’ll drink my semen after I ejaculate, right?”

“Yeah.”

“From my perspective, the hurdle to doing that act is about the same. Which condition is missing?”

When I asked her, Miyu thought for a while, then hit her fist on the table.

“I see.”

Miyu seemed to understand. However, it didn’t mean that she agreed to my blowjob request.

“Basically, you’re saying that if I had parameters like in an eroge, and if the affection level needed for doing it with my mouth is 50, then the affection level for the usual act should be at least 50 as well. So, logically speaking, it wouldn’t make sense for me to refuse to do it with my mouth, right?”

“You’re absolutely right.”

“But that understanding is wrong. The necessary affection rating is not the same.”

The background of our misunderstanding was revealed here.

“Seriously…? What affection rating would make you give me a blowjob?”

“Even if it were a hundred, I’d still hesitate.”

“What about the usual processing then?”

“That’s a free affection rating, or rather, like being asked to pass the soy sauce during a meal and having to decide whether to refuse or not.”

Oh, I see. So the heroine’s settings are bugged. Where’s the patch to fix this?

However, affection rating? Hmm.

“What about touching your hair?”

“It depends on the situation, but I don’t like it.”

“What about hugging or smelling you?”

“It depends on the situation, but I don’t like it.”

“…And blowjobs?”

“I’d rather die.”

Damn it, what’s with this sister of mine? Why is she so averse to blowjobs?

“I don’t do anything that could be used as masturbation material. I’ll help you with the post-ejaculation processing, but I won’t help you get there. In other words, your little sister won’t give you a blowjob.”

She’s already being used as masturbation material. Though I understand what she’s trying to say.

“So, handjobs and titjobs are out of the question too?”

“That’s right. If you want me to do that, you’ll have to come up with a good enough reason.”

A good enough reason. Indeed, for this dutiful sister of mine, if there’s a compelling reason, she’ll do even the most unpleasant things. Unfortunately, I don’t think I can come up with such a reason, so I’ll have to give up for now.

“Wait, if I think about it that way, what about finishing in your hand?”

The thought that suddenly came to my mind slipped out.

“You want me to use my hand as a plate to catch it? Hmm… I don’t know…”

Unexpectedly, Miyu seemed to be deep in thought. Could this work?

“But… if that’s the case… Indeed…”

Miyu seemed to be solving something within herself as she looked down, troubled. Where did that “if that’s the case” come from? I really wanted to know what she was thinking.

“Well, I feel sorry for you, Onii-chan, so I’ll allow you to finish in my hand today as a special exception.”

Yes! I don’t know why her mouth is okay but her hands aren’t, but I did it!

“And of course, you’ll drink it too, right?”

“Are you in a position to say ‘of course’?”

“I’m sorry…”

“I’ll drink it, but only a little.”

Will she drink it? I can’t wait any longer.

“Alright, I’m going to finish soon, so give me a moment.”

As soon as I heard that she would catch it in her hand, my penis, which had lost its hardness, became erect again, and I began to vigorously jerk off. Miyu, who was watching me, suddenly opened her mouth.

“I’ve always wondered about this, Onii-chan, but how can you do it so openly in front of your little sister?”

So this sister of mine has always thought that. It’s because Miyu won’t give me a blowjob or a handjob that I’m doing this. I’m so angry that I want to ejaculate even more. I can feel that my ejaculate will be incredibly thick with anger and excitement.

“Umm… don’t be so harsh… fuu… it’s making it hard for me to finish…”

“It looks like it’s grown by a whole round to me.”

She’s deliberately insulting me. What a sister who understands her brother so well. I want to reward her with a huge ejaculation.

“Haa, haa… it feels so good, Miyu…”

“Is that so? Feel free to finish whenever you like.”

Miyu held out her palms, stacked on top of each other, and placed them in front of my penis. I jerked off my shaft, leaning forward so that the tip of my penis faced her hand plate.

Even though she sees me in such a pathetic state, Miyu still agrees to catch my ejaculation. The fact that she does this excites me, and it’s all her fault that I ejaculate so quickly.

No matter how you look at it, Miyu must be aware that she’s being used as masturbation material. And yet, she’s engaging in such erotic play with me.

“I’m about to finish…! Miyu, I’m going to come…”

As I declared my ejaculation, Miyu’s gaze focused on the tip of my penis.

The idea that Miyu doesn’t have any special feelings for me was wrong. Even if it’s not love, it’s something that’s enough for us to have sex. I was certain of this as I ejaculated.

“Here it comes… here it comes…! Miyu, catch it…!”

Dopyu, dopyu, dob—! The ejaculate poured onto Miyu’s palm, demanding to be refilled again and again.

“Haa, aahh… aahh… I’m cumming…”

While ejaculating, I continued to rub my penis, and as the white liquid was shot out from the cleft of my glans, I ejaculated repeatedly until I could no longer feel the pleasure.

“You’ve ejaculated so much again…”

Miyu seemed accustomed to the large amount of ejaculate in her hands, and she was nonchalant. The post-ejaculation processing was seamless, and Miyu drank the milky white pool of liquid, tilting her cup. Then, she licked her palms, cleaning the thick sperm that had settled between her fingers.

It was incredibly erotic.

“Miyu, what should I do? I can’t get an erection to go down. If I start to get turned on again, can I call you?”

“I don’t want to! You’re using me as masturbation material again!”

It’s too late, Miyu. Please understand.

“Anyway, your sex drive has been weird lately. You might get sick if you keep this up. If you keep doing it so much, I’ll limit you to once a day with supervision.”

Miyu said this with a serious look of concern. I appreciate her concern, but if she starts managing my ejaculations at this point, I’ll die.

“I understand. I won’t do it today again. …Instead, can I ask you a question?”

After being calmly admonished by Miyu, my sex drive finally calmed down.

“What is it?”

“About the analogy you made earlier. I was wondering, what’s my affection rating to you now?”

I couldn’t help but be curious when it was quantified. When I asked, Miyu made a troubled face. She twitched her eyebrows, struggled with her thoughts, and finally opened her mouth.

“Well, it’s not negative, I guess.”

Miyu gave a safe answer like that, then stood up and left the room quickly, saying, “I’m going back now.” I felt that Miyu, who had tried to dodge the question, was a little embarrassed.

I might not mind if that sister of mine manages my ejaculations. I shook off the dangerous thought and decided to focus on my smartphone game to pass the time.
