My Little Sister Is the Best F*p Material

Volume 1 Chapter 02: Her Chastity and Loyalty

When I woke up, it was morning.

The surroundings were still dim, but the soft light coming through the gap in the curtains told me it was sunrise.

It was probably much earlier than the time I usually woke up to go to school. It was a time suitable for a second round of sleep, but my consciousness was so clear that it was a waste to go back to sleep.

“Guess I’ll masturbate.”

I suddenly thought so. I wasn’t feeling horny, but I wanted to comfort my hard, erect penis, which was standing up regardless of my feelings.

I grasped my hard, swollen penis. Maybe because it was morning, I couldn’t put much force into it. Still, from the moment I decided to masturbate, a pleasant sensation was rising from the inside of my testicles.

Thinking that I might cum soon, I continued to masturbate. I remembered the erotic games I had played in the past and converted them into my favorite situations in my imagination. That alone was enough for me to masturbate without watching any porn videos. — or so I thought.

It had become too much of a hassle to remember past images. Instead, just imagining that my sister was watching me masturbate made me feel the urge to ejaculate already. It seemed that my body had recognized Myu as the only target for ejaculation.

I even imagined a convenient plot twist, like maybe we weren’t blood-related, while I surrendered to my right hand, which was moving automatically.

“Aah… I’m about to cum.”

I felt my testicles rise, and I continued to masturbate without even preparing a tissue.

“You’re about to cum already?”

A gentle voice that I had finally gotten used to hearing recently reached my ears. I noticed that Miyu was sitting on the chair next to me. Did I mistakenly fall asleep in my sister’s room? That had never happened before.

“Can I cum on Miu?”

I asked my sister, who was watching my masturbation with her hands on her knees, if she would receive my ejaculation again.

“I don’t mind.”

Miyu replied without hesitation. I didn’t know what kind of sensibility she had, but this sister of mine had no problem watching her brother masturbate or even drinking his semen. She didn’t do it willingly, and she sometimes refused, but she usually gave her permission smoothly.

I moved the futon aside and positioned my fully erect penis upright. Miyu then approached the bed, removed her panties, and hiked up her school skirt.

Miyu straddled my crotch and placed the head of my penis against her slit. Her lustrous black hair, which fell in a bold statement, bore the emblem of the school I had attended. The combination of a pristine white blouse and pleated skirt was so provocative, it was as if it were designed to stimulate male lust.

Her body, though still young, was ripe, and she must have been the center of attention at school. Although I didn’t have much interaction with my sister, as her brother, I felt proud of her beautiful appearance.

“Alright, I’m going to insert it.”

I just watched as my penis was inserted into her still-innocent vagina. I could almost hear the sound of “zup,” as the love juice, which seemed to be overflowing, was pushed out and dripping down the shaft as it went into her honey pot.

Her vagina was very wet. Miuy rubbed the frenulum with her well-relaxed labia and began to stimulate my penis with her undulating waist movements, trying to make me ejaculate quickly and efficiently.

“Ah, crap. I think I’m about to cum, but isn’t this bad?”

I wasn’t wearing a condom, and she was my sister. What was I doing?

“What is?”

Miyu, who was looking down on me in the cowgirl position, asked.

“No, I don’t know. I can’t quite understand, but my chest feels restless.”

“Hmm.”

The cheap bed frame creaked, “Gii, Gii,” in time with Miyu’s waist movements.

“Sorry, I’m about to cum.”

“Okay. Let me know when you’re done.”

In response to my ejaculation declaration, Miyu quickened her hip movements. This sister accepted the fact that she would be creampied with just one word, “Okay.”

As for me, I didn’t even move my hips, and I was passively waiting to ejaculate inside Miyu’s vagina.

“Wait, wait!! Creampie is not good…!!”

At that moment, my consciousness finally woke up. My heart was pounding, and I desperately tried to lift Miu’s waist, but it wouldn’t move at all.

“No! Miyu, aah… kuh…”

The moment of ejaculation came mercilessly, with a “dokun, dokun.” Was my reproductive organ, which was still inserted into Miyu’s vagina, able to expel the lukewarm semen, or did it manage to escape to the outside?

— I didn’t know.

“Haa… haa…”

I woke up this morning, breathing heavily and feeling discomfort in my wet shirt and pants. There was no sister riding on my lap, and the futon was surprisingly neatly covering me.

“Seriously…?”

I couldn’t help but mutter to myself. I had never even fantasized about having sex with a classmate, yet I had a dream where I creampied Miyu. As her brother, no, as a human being, is this okay?

When I removed the blanket, I saw that there was a clear stain on my pajamas. It was as if I had wet the bed. The amount of semen was not just one or two times. My pants must be soaked in semen. How much did I want to ejaculate inside Miu?

“Haa…”

“You seemed to be having a nightmare. What happened?”

“N-Miu!? No, this is…!!”

By the time I heard the sound of the door opening, it was too late. Because the bed was in a position where it could be seen immediately from the door, Miyu’s gaze was naturally directed at my soaked pants. It was thousands of times more embarrassing than being caught playing erotic games.

Oh, I can’t do this. This time, my heart was truly broken.

“I’m sorry for opening the door without knocking.”

Miyu apologized sincerely, as if she could sense my wounded heart. Usually, I should be the one apologizing for exposing myself like this.

Still, as a brother who wanted to enjoy a safe masturbation life, the lack of a knock was a serious problem, so I didn’t correct her.

“I’m going to take a shower.”

I got up, feeling the sliminess in my lower abdomen.

“I don’t really understand, but you seem to have ejaculated quite a bit, right? Won’t some of that semen fall to the floor if you walk around in that state?”

Miu opened the door and entered the room. How did she know that when she didn’t know? Maybe this sister of mine does know everything.

“I can’t accurately gauge how much I’ve cum, but I don’t want to stick my hands into my semen-soaked pants, so I’d like to take a shower with them on.”

“But if you do that, the drain will get clogged, won’t it?”

Miyu came closer to me, who was still lying on the bed. She sure had some strange knowledge.

“Well, if it’s just your pants, it should be fine to take it off, right?”

“Yeah, probably.”

I was stripped of my stained pants by my sister. Then, Miyu carefully observed my legs from my knees down. It seemed that no semen had dripped onto my legs or the sheet.

“It seems like it all came out in your pants.”

I ignored Miyu’s report on my wet dream, as if it were to my right ear. I didn’t want to move my body unnecessarily, as the semen might flow out, and my muscles were getting tired from the tension.

I didn’t even feel like thinking about what kind of situation this was. Having my wet-dreamed lower body confirmed by someone else was much more embarrassing than being caught in the act of ejaculation.

I was glad it was this sister of mine. If it had been another sister, it would have been a family conference.

“I’ll take off your underwear, too.”

Miu put her finger on the elastic of my underwear. I realized, after about ten seconds, that she was looking at my face intently, meaning for me to lift my waist. Carefully lowering my underwear, a half-hidden penis, which had shrunk after expelling its lust, lay there.

The mental damage was added, and my brain shut down due to my defense mechanism. Miyu had only seen my penis in an erect state, so she didn’t know about this pathetic state of my genitals.

I looked up at the sky with a blank mind, trying to escape the guilt of dreaming of creampie Miyu and the humiliation of making her take care of me.

“Well… it’s a physiological phenomenon, so I think it’s okay. I’m really sorry for seeing it, though.”

Miyu’s voice also lacked energy. Miyu didn’t know the content of my dream, so she probably thought I was this depressed just because she had seen me wet-dreaming.

I wanted to tell her that it wasn’t like that, but being comforted in this situation was comfortable for me at the moment. Considering that the cause was me, if I hadn’t been seen by Miu, I wouldn’t have felt so miserable, so I should be able to accept a little sympathy.

“I’ll just clean up the parts that are about to fall off.”

When I looked at Miyu again, she had given up looking for a place to put my semen-soaked pants. Holding the dry part of the pants with the tip of her fingers, she skillfully balanced herself with her elbow and brought her face close to my groin.

“Aah… ohh…”

A strange voice came out of me.

The warm, sticky sensation was transmitted to my genitals again. I realized that it was Miu’s tongue, and my head went into panic mode.

“Miyu… it’s dirty…”

Mitu was licking the semen that remained at the exact position where my underwear didn’t touch, around my hip joints and above my bladder.

“Huh?… Is it?”

Miyu raised her face once and took a breath while looking at my groin. Her expression was as unfriendly as always.

Well, I took a bath yesterday, and my pajamas and underwear are freshly washed. I can’t say there’s no dirt because I’m sweating, but it was difficult to explain to this sister, who can drink semen without a care, that it was messy to lick up the semen that came out from a wet dream.

“I can’t get the one that’s stuck to your hair, so try to get it off yourself. I’ll wash your underwear.”

Miyu once again attached her mouth to my crotch and began to suck up the remaining semen, her lips sliding across it.

“Kuh… haa… Miu… that…”

With each stroke of her tongue, my body trembled with pleasure from the core. Was it this good to be licked on the body?

“I acknowledge that I feel sorry, but don’t get the wrong idea, Onii-chan.”

Miyu, looking sideways at my growing penis, spoke to me in a cold voice.

“My apology only includes not letting your semen fall down the floor.”

Chub, she sucked up the last bit of white, and Miu got up.

It seemed to be over, but in this kind of situation, just having the dirt licked up was like a bashing scenario in an erotic game. My hungry mind, feeling unsatisfied, was considering two options.

Should I make my sister feel more guilty and apologize more? Or should I just let her go without saying anything?

The first one, the first one. It seems that Miyu really hates leaving a debt or grudge unresolved. If I say I won’t forgive her, she probably won’t just let it goNo matter how I thought about it, it was not impossible. A girl who would lick my penis after a wet dream wouldn’t have any reason to resist a blowjob.

Say it. Tell her to suck it.

If she really feels sorry, there’s no way she would go home without licking the most important part.

“Uhm, from now on, I’ll properly knock so… I’m sorry..”

Miyu said so, looking down.

To which I could only reply,

“If you start to be careful, then that’s okay.”

As I watched my sister’s back leave the room, I took a deep breath. I held my breath for a moment, then exhaled like letting the air out of a balloon.

“Aah. I can’t stop it, I’ll masturbate to Miyu.”

As if the massive wet dream I had had was a lie, I grasped my penis, which was now at its hardest. And after two minutes of letting off steam, I headed to the bathroom, covering my groin with the hem of my T-shirt.

Miyu, who was washing my underwear at the washstand in the changing room, had a normal expression on her face, neither angry nor disgusted, and when our eyes met in the mirror, she said, “Good job.”

While I was undressing, turning my back on my sister, I tried not to think about anything in my head, but my heart, which knew that I was using Miyu as my masturbation material, continued to beat wildly, reprimanding me.
