My Little Sister Is the Best F*p Material

Volume 1 Chapter 1.2:

“Haa… Biyu… Biyu…”

As soon as I returned home from school, I realized my sister wasn’t there, so I decided to masturbate with an erotic game.

“Damn… haa… damn it… why…?”

No matter how much I rubbed my penis, I couldn’t feel the urge to ejaculate. My penis was standing at full attention, but…

Even my favorite erotic scenes didn’t work. Using lotion didn’t help either. In the end, I even took out my long-sealed onahole and stimulated it to the limit, but all it did was tire me out and make my erection fade.

I knew the cause. It was Miyu. Since I had cum on her, I had only masturbated once in these few days, and it was using my real sister as my masturbation material.

I admit it; I couldn’t masturbate by gripping my penis because it was too stimulating. Even lightly rubbing it with my fingertips, I could barely hold back my orgasm for a minute. That’s how good it felt to masturbate using Miyu as my masturbation material.

“What the hell am I doing…?”

Frustrated and empty, I finally stopped moving my hand. I closed the erotic game screen, went to the second-floor sink to wash off the lotion stuck to my groin, and decided to take a bath, descending the stairs.

“Oh, Onii-chan. You were here.”

As I passed through the living room to get some water, I saw Miyu, in her school uniform, lying on her back on the sofa. She was holding a manga and had been reading it for a while after returning home. I was too busy trying to cum to notice her.

That was close. She would’ve seen me masturbating again if I continued.

What would she have done next?

“Yeah.”

I replied as I usually would, as a socially awkward person.

Even after what had happened, she spoke to me normally. I had thought she was avoiding me, but come to think of it, Miyu had never insulted or criticized me.

“… What manga are you reading?”

I gathered the courage to speak to her. Then, I took a canned juice from the fridge and leaned my back against the sofa’s leg.

“It’s called ‘Half Game,’ a supernatural mystery.”

“Hmm.”

It was a manga I didn’t know, so I couldn’t continue the conversation. I had read a lot of manga in the past, so I was confident that I would never run out of topics. Apparently, a rich repertoire of topics isn’t the only thing needed for conversation with others.

The silence continued, and I drank the canned juice to pass the time. I placed the can on the table and leaned back against the sofa’s leg again, and that’s when I noticed it.

(A girl’s uniform… bare legs… so erotic…)

I had always thought three-dimensional reality was crap. Still, I would follow the female students on the street with my eyes. No matter how much I was into two-dimensional media, my body was honest.

As evidence, my groin, which had completely lost its vigor, was now erect, forming a respectable tent.

(Damn… if Miyu looks at me, she’ll see that I’m hard…)

Still, I couldn’t move. Suddenly standing up and moving or changing my position to hide my groin would be unnatural. More importantly, the inappropriate emotions that had sprouted within me didn’t allow me to escape this situation.

(I want to masturbate…)

My flaccid penis, which had been exhausted and limp, was now painfully erect again. It was as if it were about to burst. Although it was only of average size, it now felt impressive to me.

The panties visible between Miyu’s thighs were incredibly erotic. I should have been used to seeing her underwear, as I saw it every day in the laundry, but…

“Miyu.”

I think I was out of my mind at that moment.

“What is it?”

out it.

Miyu replied while reading her manga. Although there had been no direct contact, Miyu was the kind of sister who would help her brother masturbate. That was enough for me to be certain of my following actions.

“Can I pull it out like this?”

When Miyu heard my words, she finally looked at me.

At the peak of the tent I was supporting with my erect penis.

“Sure, go ahead.”

She gave me a curt okay. Miyu went back to reading her manga.

For some reason, I had gotten her permission. Yet, I hesitated to take off my pants. Unlike the last time, when I had exposed my genitals from the start, this time I had to expose it myself.

And at the same time, it was an act of acknowledging my sister as a sexual object. I, an avid believer in two-dimensional media, who had always dismissed reality as crap, had fallen this far after being caught masturbating just once.

“Alright, I’m going to do it.”

First, I took off my pants. It might have been easier to take them off in one go. The bulge of my erect penis in my underwear was quite something.

Miyu sensed my movement and glanced at my groin, but she didn’t seem to change her attitude. It was a complete agreement.

If that was the case, I had no more doubts. I took off my pants, too, exposing my lust-drenched penis. I gripped my erect penis and stared at Miyu’s legs. It didn’t take long for my hand to start moving.

“Haa… haa… hmm…”

I should not have been making any noise when I was alone, but for some reason, I couldn’t hold back my breath when Miyu was watching me.

“Hey, Miyu.”

I was getting too turned on, and my head was spinning, and the pleasure was increasing.

“Can I touch your legs…?”

Touching a female body. It was an act I had always forbidden myself to do, as I had denied three-dimensional reality. But deep down, my interest had been growing.

“No.”

She flatly refused. So be it. In that case, I would ogle her to my heart’s content. I was already masturbating, using my sister as my masturbation material, and she was right in front of me.

This is bad. Even though I had been masturbating so much earlier, I now wanted to ejaculate so badly.

“Fuu… u… haa…”

The glans, squeezed with blood and turned bright red, was sending me signals to ejaculate. I smelled the scent of her legs without hesitation, and I was so excited that I didn’t know what to do with myself.

“Ah… Miyu… I need a tissue…”

I had no place to cum. I had been refused to cum on her thighs, and I had been scolded for getting cum on her clothes. If I just let it go in the living room, the semen would stain the carpet.

“Miyu… I’m… about to cum…”

“Hmm? You’re about to cum? What should we do? This manga is borrowed, so if you get it dirty, you’ll have to pay for it.”

Miyu acted as if it were someone else’s business. As if she weren’t the one being used as my masturbation material.

The fingers of my right hand began to rub the frenulum fiercely, and I could no longer hold back. I didn’t want to go look for a tissue and process it myself. I wanted Miyu to receive it. Like before. I wanted to ejaculate in front of Miyu.

“Miyu, sorry, but can you put the manga down and catch it?”

I stood up and masturbated in front of Miyu, who was lying on the sofa. Miyu seemed to sense that I was about to ejaculate and put the manga on the sofa’s armrest, ready to catch it.

But her response far exceeded my expectations.

“Hmm…”

Miyu speaks with a stuffy nose and tells me, “Please go ahead and cum.” It seems that she misunderstood my wish for her to hold her hand as a plate to catch it to instead have her receive it with her mouth.

Miyu’s mouth opened, and she waited for me to ejaculate.

Her red tongue, moist with saliva, covered with the lower lip, was preparing to drink my semen.

“Haa… guh… Miyu… I’m cumming… cumming…!!”

I ejaculated into my sister’s mouth.

The sense of guilt I felt at that moment of losing control was nothing compared to the last time.

Again, I felt the sensation of something sticky flowing through my urethra, and the white, viscous liquid filled Miyu’s mouth.

“Ah… nn…”

Miyu was indeed surprised, and she tightened her eyes slightly. In the living room lighting, even the veins in her pink mouth, visible to the naked eye, were coated with my semen, which dripped down her throat.

“Just a little more… cumming…!!”

I squeezed out every last drop. My semen filled Miyu’s throat, which she had blocked with the base of her tongue.

Miyu confirmed that my ejaculation had stopped, frowned, and then swallowed my semen down her throat.

“Ugh… it’s bitter… You release something like this? Was it semen or something?”

Miyu glared at me while complaining. She didn’t know the taste of semen?

There are many girls who don’t like oral creampies, but based on her response, it seems that Miyu is not one of them. If that’s the case, it means she hasn’t had this kind of experience before. Is she actually a girl who only has knowledge but doesn’t know men? Does she even have a boyfriend?

“Um, Miyu…”

“Hmm?”

I caressed the glans with my sticky fingers.

“Can you clean just the tip…?”

I wanted to feel her mouth, even just a little. Maybe even get a blowjob while she was cleaning it up…

“No.”

Miyu took the manga again and turned away from me. But it seemed that she was only indicating that she wouldn’t give me a blowjob and wasn’t upset.

I don’t understand her standards, but it’s nice to have her clearly refuse. It would be much more troublesome if I were unknowingly disliked.

“Um, can I ask you something?”

“What is it?”

Miyu responded to my question while looking at her manga.

“You don’t dislike drinking semen?”
