My Little Sister Is the Best F*p Material - Volume 1 Chapter 03.2

Volume 1 Chapter 03.2

“— By the way, I had a thought…”

As usual, it was after school. In the living room right after I got home, I asked Miyu.

“You said it was gross when I tried to cum on your thighs. How is that different from receiving it in your mouth?”

I had been wondering about it for a long time. Normally, if you have a healthy mind, you would be more resistant to drinking cum than having cum dripped onto you. Even if it was wrong to ask this sister of mine if she had a healthy mind, I couldn’t accept this.

“Why?”

Miyu, who was lying on the sofa, asked me back. If I were asked why, I would have no choice but to answer honestly.

“Well, you know. If it’s okay for me to cum in your mouth, I think it’s okay to cum in other places, too…”

In terms of convenience for processing, the mouth is overwhelming. There’s no need to wipe or wash, just swallow it. That alone is enough reason to use the mouth. However, Miyu clearly stated that “it’s gross to cum on your sister.”

“Are you not satisfied with my mouth?”

Miyu asked me another question, postponing the answer. I felt like her voice was slightly emotional, though I might have misheard.

“I’m not dissatisfied, I’m just curious. Isn’t it gross for me to cum in your mouth?”

Normally, it is. Anyone would say so.

“Mmm…”

Miyu crouched down, hiding her face with the manga. What was that reaction?

“Well, you know…”

Miyu only showed her eyes from under the cover.

“My body always touches my clothes right?”

Miyu said.

I tried to chew on her words in my head a few times… but no. I’m sorry. I don’t understand what my sister is saying. Clothes? Are clothes that important?

“Oh…”

When I thought about it, I remembered. The first time I ejaculated towards Miyu, a considerable amount of semen had landed on her clothes. I didn’t think much of it because I was in a daze at the time, but I was scolded quite a bit.

“So that’s it, the clothes.”

I guess I understand the reason. But why was she so embarrassed to answer? The story makes perfect sense, doesn’t it?

“So, it’s because the place where the semen gets on becomes sticky, and you don’t like the clothes touching that place, right?”

“Yeah, something like that.”

It seems like the clothes are more important than the body. My little sister is still full of mysteries.

“Then, if it’s just before you take a bath, is it okay if I cum somewhere other than your mouth?”

“Umm… well… I guess it’s okay…”

Miyu answered again, unemotionally and calmly.

“What? It’s okay!?”

“Yeah.”

Miyu, who was reading her manga, gave me an empty reply. Oh no, my head is not working well with this joy and surprise.

“So, can you tell me when you’re going to take a bath?”

I have to strike while the iron is hot. I want to ejaculate before she changes her mind and says, “I don’t want to after all.”

“You’re going to cum again today?”

“Uh, yeah.”

An unexpected question, and my guilt returned. I’m sorry, for being a brother who masturbates so much.

“But by the time Mom and Dad come home, I think I’ll hate taking a bath in the bathroom…”

My sister hesitated.

“What about now?”

I persisted. I can’t give up.

“Now?”

Miyu put the manga aside and sat up.

“Do you want to cum?”

I felt my penis react with a twitch. Of course, I was going to cum when she looked at me with those big eyes and asked me like a child, “Do you want to cum?”

“I want to.”

I had a strong desire to cum, regardless of the reason. That alone was enough to get my way.

“Mmm…”

Miyu looked troubled. This is a difficult situation. Miyu hates to be bothered. It’s probably not something she wants to do, to get in the bath early just to respond to my request.

“You know, I have something I want to confirm first.”

Miyu asked me in a slightly shy voice.

It was a completely different atmosphere than usual. I felt a shiver at the base of my neck, and my mouth went dry. What is this feeling? The air was tense and rough. It was a familiar sensation. It was like the unpleasant atmosphere when I confessed to a classmate I couldn’t quite say I liked or didn’t like, and was subtly rejected.

“Onii-cha, are you trying to use me as your masturbation material?”

Miyu asked me seriously.

I shook my head instinctively and suppressed my anxiety.

“No, I’m not.”

My voice was hoarse because my mouth was dry, but it seemed to reach Miyu’s ears properly, and I was able to get her usual compromise, “Then it’s okay.”

— Wait, my dear little sister. Didn’t you acknowledge that I use you as my masturbation material?

“You can cum anytime, right? And I won’t forgive you if you cum on my face or hair.”

“Of course. I’ll make sure to cum in a safe place.”

“I see.”

Miyu seemed to be satisfied with my answer, stood up from the sofa, and went to the bathroom instead of me. As she opened the living room door and stepped into the hallway, Miyu turned to me again.

“Do you understand what I said earlier?”

My sister glared at me with narrowed eyes. What she said earlier was about using her as my masturbation material, right? I understand, I understand. But is it really not okay to use you as my masturbation material? I can’t ejaculate without you, but…

“I’ll get angry if you sniff my clothes.”

I straightened my back involuntarily at the strong tone of her words.

“I, I won’t.”

I answered in a stutter, like a robot, stiffening my body. Miyu seemed satisfied with that answer and went into the changing room.

“Haa. So that’s it.”

I sighed and relaxed. It seems that she has an extraordinary attachment to her clothes. In other words, there doesn’t seem to be a problem as long as I don’t touch her clothes or body carelessly.

Still, I can’t sniff her? As I reconsidered with a relieved heart, I realized that I had been told something very disappointing. The scent of a girl was an important factor that couldn’t be experienced in a game.

“Should I go masturbate?”

I followed Miyu and headed to the changing room. When I opened the door, Miyu, still dressed, was waiting for me.

“Is it okay to stay like this?”

“This hair? I’m not going to soak in the bathtub, so I don’t need to tie it up.”

No, that’s not what I meant. I meant her clothes. I came to the bathroom because I didn’t want to cum on her clothes, but Miyu had to take off her clothes for this to work.

Of course, I wanted to observe Miyu’s tied-up hair up close, as it was quite rare. But first and foremost, I wanted to worship her naked body. I was curious about how her small body supported her disproportionately large breasts. Usually, Miyu changed in the changing room, so I couldn’t see her naked.

“Then, you should take off your underwear, Onii-chan. Get ready to ejaculate.”

“Huh?”

“Not ‘huh’. You can’t do it without taking them off.”

“That’s true… but…”

This sister doesn’t want me to use her naked body as my masturbation material. Damn it, I want to take off at least one piece of her clothing.

“If you just show me you with your underwear, I’ll cum faster…”

“Isn’t that because you’re using me as your masturbation material?”

“I’ll mentally convert your naked body into that of another girl.”

“If you can do that, then you should imagine that girl’s naked body from the beginning.”

“Okay.”

I was scolded, so I decided to masturbate obediently.

I exposed my lower body in front of Miyu. I had to masturbate in front of Miyu until I was about to ejaculate, just a few more rubs. However, it was not a problem for Miyu to be my masturbation material even if she was wearing clothes. It was just a matter of whether it was fast or slow.

Miyu, who had just returned from school, was wearing her uniform, a prescribed blazer, and it was clear from the outside that it fit her body perfectly. That’s why the eroticism of Miyu’s clothed body stood out, and the contrast with her purity excited my groin.

“Aah… damn… I think I’m about to cum…”

Miyu could be used as my masturbation material no matter what aspect of her I chose. No matter how many times I used her for masturbation, I never got tired of her. Reminding myself that my sister was so strict and serious in reality made my fantasy even more intense.

“You sure cum fast, Onii-chan”

Zukin, it echoed in my chest. Overwhelmed by the avalanche of misery, I almost ejaculated, and I stopped moving my right hand.

“I… I’m sorry…”

“There’s no need to apologize. It’s helpful for me, and I’m relieved.”

I hung my head, but I resumed masturbating.

I was thought to be a premature ejaculator. It was true, but the cause was Miyu. I just wanted her to understand that.

“If you’re about to cum, I’ll take off my clothes.”

“Oh, yeah.”

I see, if I was about to cum, Miyu would take off her clothes.

… This is bad, I’m getting excited at the expectation, and I might cum soon.

“Just so you know, if it takes too long, I’ll stop.”

“I know. I just have to cum quickly, right?”

“Alright. I’ll take them off, so close your eyes.”

“Why?”

“Because I’m taking them off. Are you stupid, Onii-chan?”

I don’t understand, as I’m stupid, as Miyu said. Why do I have to close my eyes when my masturbation material is right in front of me?

“As I thought, you’re using me as your masturbation material…”

“I’m not! I’ll close my eyes! Please, come on!”

When masturbating with my imagination, visual information is not necessary. That was Miyu’s claim. How stubborn she was, even after all this. But I had no choice but to obey.

When I closed my eyes, I heard the sound of Miyu’s clothes rubbing together as she took them off in the darkness beyond. That faint sound made my heart race, and I was driven to ejaculate.

Hurry up and take off your clothes. I can’t cum without seeing Miyu’s naked body, even before I worry about getting angry if I cum on her clothes.

“… I’m about to take off my underwear. Please don’t peek with your eyes half-closed.”

“Umm… mm… yeah… I’ll keep that promise…”

This sister of mine was trying to make me cum with just her words. I was keeping my promise and not looking at anything, but I couldn’t help but imagine her taking off her underwear.

“Um… well, I’ll go into the bathroom. After that, you can do whatever you want.”

“Can I open my eyes?”

“Yeah.”

Miyu finally gave me permission. I opened my eyelids, my heart pounding. There was—

“Oh… Mi, Miyu…”

Miyu, with the maximum amount of skin exposed, was squatting in the bathroom, covering her nipples and crotch with her arms.

I stepped into the bathroom and observed Miyu’s naked body, licking my lips. Her skin was completely white, with no tan lines, and she had a soft, plump body. The only part of her that was slightly red was her face.

“A-Are you okay?”

“Umm… well… I’m a little bit regretful.”

That so? it’s too erotic. I’m cumming.

“Miyu, I’m about to cum… I’m going to cum on you like this…”

Miyu was unusually not looking at me masturbate, but lowering her eyes in embarrassment. Seeing Miyu’s somewhat brave figure, my desire finally reached its peak.

“Aah, guh, aah… Miyu… I’m cumming, cumming…!!”

Bukukubuk, semen flew out of the urethral meatus, and I sprayed hot semen all over Miyu’s body. It attached to Miyu’s raw chest, arms, and legs, drawing low-arcing parabolas, and then I was hit by the smell of chlorine.

“You’re cumming too much on your own sister’s body.”

Miyu was half-reprimanding and half-scolding me. Miyu picked up the semen that had landed on her thigh and held it in front of her face.

“I’m sorry. It felt so good.”

“I see.”

Miyu ignored my words and put the semen she had picked up into her mouth with a snap.

… What is with this sister of mine? Isn’t she an incredibly erotic woman?

“Why do men like to cum on girls?”

“Well, how should I explain…?”

It seems that Miyu has been studying about sex since she witnessed my masturbation. It seems that she learned that bukkake is a genre that makes up a large proportion of erotic works.

“It’s probably a psychological desire to mark. However, in my personal opinion, it’s just that I get excited when a cute girl is soiled with semen. … This is difficult to explain to a girl who doesn’t have a penis.”

“Is that so?”

Miyu seemed to be satisfied with that answer alone.

“By the way, you’re going to wash it in the bathroom, right? Isn’t it a problem if it clogs the drain?”

“If it does, I can just rinse it with cold water, or clean it up if it’s really bad, so you don’t have to worry about it.”

Then, what was that service when I wet-dreamed the other day? It was very helpful to me, but…

“I see, I’ll take a shower then. Also, I was really embarrassed, so I won’t do this again. I’m sorry, but if you want to cum, do it in my mouth.”

“I, I understand.”

It’s a pity. But as long as she processes it with her mouth, I have no problem.

I watched Miyu close the bathroom do

or with a resentful look and left the changing room. My head was clear.

“My sister is incredibly erotic…”

The image of Miyu, who was hiding her naked body shyly, was burned into my mind.

I looked at the distant stars, recalled that image, and once again deeply thanked Miyu for her existence.
