My Little Sister Is the Best F*p Material

Volume 1 Chapter 11: It’s only when others change that you do

Reality was less exciting than what I imagined.

Even though I was late, my homeroom teacher only asked if I had overslept. Although I did attract some stares when I entered the classroom, no one made fun of me before class started.

I’m not particularly outgoing at school, but it’s a bit lonely that no one reacted to my change. I’m grateful for all the effort Miyu put in. I guess that’s just how much people care about others.

Maybe I was being too self-conscious. If I think about it, I don’t notice when girls cut their hair, and even if Suzuhara came to school with a new hairstyle, I wouldn’t really care.

I feel bad about not being able to give Miyu a proper report when I get home, but I don’t have the luxury of worrying about that right now. I have an obligation to fulfill.

I must talk to girls. When I come to school, I must have at least one conversation with a girl. That’s one of the promises I made with Miyu.

Yesterday and the day before, I asked Onozaki, who is relatively easy to talk to in our class, questions about our lessons. After all, she sits next to me.

It’s still too difficult to talk to other girls. Miyu wants me to talk to Yamamoto-san, but she’s not only out of my league, but also a popular girl, so there’s no opportunity for me to even start a conversation with her. Besides, getting talked to by her doesn’t count as me fulfilling my promise to Miyu.

Still, it’s not right for me to keep clearing the condition by talking only to Onozaki. Miyu can’t check if I’m actually talking to girls, but that’s why I must faithfully follow her intentions. In the end, it’s for my own good. I must repay Miyu for all she did for me this morning.

“Onozaki, you always have a strap attached to your bag, huh?”

It was almost the end of the break, just a few minutes before the teacher came in. In the end, I talked to Onozaki, but this time I brought up a topic unrelated to our lessons. This is a great step forward.

“Huh? This?”

Onozaki showed me a strap attached to the end of her pencil case, the same as the one on her bag. It’s from the loose-faced glasses animal series. Since Onozaki also wears glasses, she probably feels a connection with it.

“Yeah, I’ve been seeing them a lot at convenience stores lately.”

“That’s because they started selling the gashapon figures. Originally, it was the image character only for instant coffee, but the ‘Matarica Cafe’ series sold really well.”

Onozaki explained the details while playing with the strap. It was originally a low-key sales strategy, but it became explosively popular thanks to the so-called “high school girl effect.”

“Hey, Sotomichi-kun…”

Onozaki started the conversation this time. She glanced at me casually, leaned closer, and spoke in a small voice.

“Did you get a girlfriend?”

I couldn’t help but do an inner high-five.

Although I didn’t want to be asked that, I was somehow expecting those words, and now I finally heard them. So I wasn’t unnoticed after all.

“Not yet.”

I said “yet.” That’s not like me. My girlfriend should have been on the other side of the screen a long time ago.

Still, this is a good thing. Since she asked if I had a girlfriend, I can consider my manliness to have increased. Although I can’t see the effects of my workouts yet, my posture, which was starting to become hunched, has improved recently, so it’s probably not unrelated.

“Oh, really? Fufu. You have a good air around you today.”

Onozaki smiled at me with a gentle expression.

Hey, wait a minute. I’m getting too full of myself. Thinking that I’m too popular is gross. This is normal. It’s not something special.

Don’t get carried away, me. Don’t think that maybe Onozaki likes me. Absolutely not.

“Umm, thanks.”

I hid my excited heart and calmly expressed my gratitude.

I can’t believe something like this would have happened. On the contrary, I’m starting to become aware of Onozaki. If things keep going this way, maybe the problem of only getting erect for my little sister will be easily solved.

Onozaki, huh? She doesn’t have breasts, but she seems like the type who would become surprisingly proactive if the mood was right. If she took off her glasses, her vision is poor, so her eyes would look bad, but it would be like being glared at while having sex. Although she looks like she doesn’t have any male interest, it’s possible that she’s actually experienced. If she were on top of me, she’d probably start moving her hips herself… Oh, just thinking about it gets me excited.

“…”

Damn it, I can’t get erect. Why? It’s reacting a little. Maybe I’m tense because she’s right next to me.

“Alright, be quiet. Let’s start the lesson. Class representative, give the command.”

While I was fantasizing, the teacher came in.

From now on, I have fifty minutes of math class. If I finish the work in advance, I can still spend the remaining time fantasizing. I’ll quickly finish it and re-enter the erotic world. Before this excitement cools down, somehow I must get an erection for a girl other than Miyu.

“Damn it…”

I failed. In the end, I couldn’t get fully erect until the last lesson. But I haven’t completely lost. I got at least half-erect. If I keep this up, in a few days I’ll be able to get a full erection without using my little sister as a masturbation aid. Today, I’ve made remarkable progress in every way.

Suzuhara also asked me, “Did you get a girlfriend or something?” He wasn’t as angry as when I was doing day leader duties with Yamamoto-san. It seems like he’s fine as long as Yamamoto-san isn’t friendly with other guys. When did he become such a passionate fan? Suzuhara is supposed to be a two-dimensional believer.

Oh well, I’ll stop thinking about it.

Even though I didn’t have gym class, I was exhausted walking back from the music room. The glucose I consumed during breakfast and lunch was long digested and gone.

I went through all my classmates as masturbation materials just to get an erection, but what if it were Miyu? It’s become clear that I can’t use Miyu as a masturbation materials in the conversation flow I revealed to her. However, my relationship with Miyu is also progressing little by little. Recently, Miyu has been talking to me more often, and when it comes to clothes-related topics, she’s even proactive.

Considering this, it might not be so difficult to find out why Miyu gives me fellatio and handjobs. For example, I could ask her as a reward for me trying hard at something. She’s definitely the type who can’t refuse a favor. When I was caught masturbating for the first time, and when she helped me deal with my wet dream, Miyu was very concerned about loans, debts, and equality.

Even if she gives me a fellatio, she’ll probably just do it expressionlessly, but there’s hope, right? Miyu will definitely drink it. Next time, I’ll try abstaining from masturbation and saving up. I want to see how much of a thick one I can make her drink when she accepts it with that serious expression.

“…”

This is bad. I’m fully erect.

In the hallway after class, when there are so many students around. This erection of mine was so hard that I can’t really hide it with my textbook.

The toilet was occupied by an acquaintance earlier, and it’s too far away. Most importantly, if there’s no vacant stall, that would be the worst-case scenario.

Fortunately, this is on the first floor. If I go behind the stairs, there’s a blind spot where no one will find me unless the emergency exit is used. That should be the best place to calm down my bulge.

I confirmed that no one was nearby, then I ran to hide behind the stairs.

“Phew…”

It’s all Miyu’s fault. I never expected to get an erection so easily. Today’s fantasies were all about getting fellatio from her, so that’s probably why.

I want to be sucked by her with that grumpy face. Not noisy sex filled with dirty talk, but a calm sex where I’m prompted with a “Are you not done yet?” expression.

Why is this? I shouldn’t have this kind of taste. My ideal was to have a lovey-dovey relationship where we whisper our love to each other while embracing each other. For over three years, I’ve been passionate about eroge and have longed for such a relationship. Yet now, even being scolded by Miyu excites me.

No, this is bad. I mustn’t think about erotic things anymore. Although the break before homeroom is relatively long, if I keep going like this, I won’t be able to calm down unless I ejaculate.

It was a mistake to try to get an erection for other girls, which unknowingly accumulated my sexual desire. My libido is exploding. If only Miyu were here, I could have ejaculated just by telling her about it.

“I found a bad boy.”

A shiver ran down my spine, and as I panicked, a soft body temperature hit my back. The owner of that strangely sweet voice was none other than her.

“Y-Yamamoto-san…?”

Her long hair spread a feminine scent, and her pheromones filled my nostrils. This scent that resonates in my groin, so full of lust. I’ve been found by the person I should never meet right now.

“What are you doing I wonder?”

Yamamoto-san asked, coming close enough to bite my earlobe.

Even from behind, in this atmosphere, she must have noticed, right?

“Umm, you know, that thing that only boys do…”

Even if a boy is not in the mood, his penis sometimes gets bigger. I don’t know if Yamamoto-san knows that, but it’s an accident that can happen anytime.

“What’s that? Do boys have periods too?”

Yamamoto-san’s hand stretched out from my waist to the front.

Oh, oh, oh, what, is, happening?

Yamamoto-san is touching my crotch. I can feel her rubbing it slightly through my clothes…!

Why is Yamamoto-san doing this to me? Is it because of my image change? This is too effective.

“Hey, Sotomichi-kun. Who are you thinking of to make it so big?”

Yamamoto-san continued her interrogation and then sweetly bit my earlobe. My bladder area was restless, and my stomach twitched as if it were being pulled. She’s not like her usual self.

“I can’t tell you…”

I can’t tell her. If I said that I was thinking about my real sister and got an erection, I’d have to evacuate.

“It’s not me, is it? It seems like you’re not really aware of me, Sotomichi-kun. Is it someone in our class? Or maybe someone from another grade? Hmm. So there’s someone else you’re looking at besides me.”

Yamamoto-san groped my pants, then slowly unzipped them. It didn’t take long for her to put her finger on the button of my tighty whities.

“W-Wait, what are you…!”

Wait, wait, wait, wait, wait. How did this happen? Why am I being undressed?

“Who is it?”

Yamamoto-san skillfully removed the button with her fingers, exposing my penis to the outside. The exposed thing was exposed to the outside air, and along with my sense of shame, a thrilling sensation enveloped my body.

“I told you I can’t tell you…”

“Hmm.”

Yamamoto-san didn’t touch my exposed part directly, but after undressing me, she stroked the inside of my knees. It’s the first time in my life that I’ve had such close skinship with a girl. Does it really feel this good to be touched by someone other than myself?

“Is that so? I guess there’s nothing I can do about this then.”

Yamamoto-san put her hand on my zipper again. Then, she grabbed my balls and put my penis back in my pants without zipping it up.

“Eh…?”

Is this really the end at such a good moment?

“Fufu. Were you expecting something?”

Yamamoto-san’s body moved away from me, and I was released from the excessive heat of her body.

“W-Why did you do this…?”

What did she want to do? I asked, but she wouldn’t give me the real answer to such a mysterious act. Yamamoto-san took a step back and distanced herself from me.

“I was just teasing you. I’ll say that Sotomichi-kun has a stomachache and can’t go to homeroom, so don’t worry.”

After saying that, Yamamoto-san left with a smile.

Would the most beautiful girl in school tease a boy she’s not close to by grabbing his penis?

I don’t understand what’s happening today at all.

“Haa…”

I tried to calm down, feeling exhausted, while being annoyed by my penis, which was still erect despite my lack of conscious awareness.

“I’ll tell you someday!”

“Nuoah!?”

Finally, Yamamoto-san suddenly hugged me from behind and then immediately ran away again.

“What the hell was that?”

Aside from her perverted behavior towards me.

Why does Yamamoto-san care about who I get erect to?
