1 - My Cute Little Sister’s Request?

Chapter 1: My Cute Little Sister’s Request? ーーーーーーーーーーーーーーーーーーーー

At twilight in the humid early summer, I was laying down while playing with my smartphone when I heard someone knocking on my door. Without changing my position, I answered.

“What?”

Father shouldn’t be home yet so maybe it was my mother? Maybe she wanted me to go on an errand?

I’m already a highschool student but my parents are still…

“Onii-chan, can I talk with you for a second?”

“Wha-What is it?”

Unexpectedly, it was my younger sister. We didn’t talk much generally as often was the case with a younger sister who was right in the midst of her puberty.

It’s not that we hate each other but it’s just, we’re not little kids anymore after all.

“I’m coming in….. You’re not doing anything weird, are you?”

“He-Hey!”

Without waiting for my reply, my little sister came in. If I were doing “anything weird” just like what she said, she would’ve caught me in the action.

“I have something I want to discuss, or rather, to talk with you.”

She said as she walked over and sat on the edge of my bed.

“What is going on all of a sudden like this?”

Using both of my feet as momentum, I got up.

“No! Stop shaking!”

Somehow my little sister was being weird. She seemed fidgety.

My little sister, Natsumi, was the ‘my pace’ type of a girl so I didn’t get to see her acting flustered or shaken often. Her appearance was appropriate for her age but she gave the impression of a more grown up woman due to her demeanor. So it was unusual for her to react like this.

“What’s the problem with shaking though?”

“If it’s shaking, it will leak.”

Hm?! ……….What will…. Leak…..

Natsumi then pulled the hem of the t-shirt she was wearing.

“Wait! Where’s your bra?!”

Natsumi’s two bulges, which were not that big by any means, gave off a white reflection under the fluorescent light.

“I took it off beforehand because it’d become a hindrance for our conversation. Don’t look at me pervertedly.”

Natsumi said so while blushing.

You’re the one who showed it to me all of a sudden.

I thought to myself but I didn’t say it out loud.

“That, it’s coming out.”

Natsumi then added while covering the center of her breast with both of her hands.

“Umm, so, given the circumstances…”

Somehow I understood what was ‘coming out’ but I was hesitant to say it.

“From my boobs, it’s coming out.”

Natsumi said shyly.

Confused, I mobilized all of my limited knowledge.

It should be coming out when you have children, right? But is there an exception to that case?

“Natsumi, are you pregnant?”

“So you see me as that kind of girl, huh.”

My little sister’s appearance was not bad so it wouldn’t be strange for her to have a boyfriend.

“You are pretty popular though.”

“Even if that’s the case…”

My little sister’s tone was getting sharper.

“………. I’m not pregnant or have already given birth. There. Well, it’s not that I’m looking for any information from onii-chan though.”

She said so while pouting.

“That’s why you need to ask mother instead. And then maybe you need to go to the hospital.”

Why is she asking me then? And showing it to me?

“That, I know already even if you don’t tell me.”

“Then why?”

“Well, I’m just curious about what it feels like.”

“What do you mean?”

My tone became harder. She was talking in a roundabout way, unlike her usual self.

“I’m curious to know… What it feels like to… Give it from your boobs….”

Oi, oi, oi…. Impossible… So you’re saying….

“So you want me to drink it.”

“We-Well, that’s what I’m trying to say.”

While being embarrassed, she said the most incredulous thing.

“You idiot. That’s impossible.”

I responded with common sense.

“But, I don’t have any other people to ask….”

“I’m not an option either, you know?”

“So I should just ask some stranger to suck it? I don’t want that.”

Is there no other option but to suck it?

“If I do that, it won’t end with just sucking you know, onii-chan.”

A greasy middle-aged man sucking on Natsumi’s nipples. Of course the old man wouldn’t be satisfied with just that. Taking advantage of Natsumi’s desperate plea, he forced himself on her, thrusting his big thing between nether regions and then, he forcibly put it inside my little sister’s immature body. Natsumi’s resistance was nothing but a vain effort. Repeatedly, the old man to Natsumi’s body……

“Wait a minute. Onii-chan, what’s the matter?”

Natsumi was staring at me suspiciously.

“Oh, it’s nothing.”

“……… You must be thinking about perverted things.”

“Yo-You’re wrong!”

She’s not wrong.

“Onii-chan, if you’re not going to do it then I will really…”

“Don’t threaten me.”

“I’m not threatening you though.”

Aaah, right. On top of being the ‘my pace’ type of girl, she’s very stubborn too. After she said her piece, she won’t accept anything else. If I want to protect my little sister’s chastity then….

“I got it. But, just for a little bit, okay?”

“Yeah, just for a little bit.”

Who would’ve thought things would end up this way.

A small protrusion could be seen in the middle of my little sister’s smallish breast.

“So I’m sucking it from here?”

“Yeah. Never mind that. You don’t need to say everything out loud.”

I then held it in my mouth.

“Nngh… Don’t lick it… Suck it.”

Natsumi’s strangely erotic voice shook my heart.

Calm down. This is just an “experiment”. It will be over after I suck it for a little bit. That’s all.

“Haah… Nngh….”

Together with my little sister’s voice, something warm was flowing into my mouth. Without particularly tasting it, I gulped it down my throat.

“Onii-chan… Nnngh….”

“Natsumi, is it painful for you?”

I said so after I took my mouth off my little sister’s nipple.

“Nngh… That’s not it but…. After your breath hits it… Nnngh….”

My little sister was wriggling in her place.

“In any case, I’ve finished it.”

I tried to close the case but then my little sister became flustered and said.

“The-The other side too.”

NO, NO, NO.

“We’re not finished yet.”

My little sister clung to me.

“But this is bad.”

“What is? Could it be, you’re feeling like doing something perverted, onii-chan?”

“Stupid… We’re brother and sister, that kind of thing is….”

Though it seemed we had already taken a step out of the boundary of normal brother and sister however, I had to stand my ground here.

“Then what is this?”

My little sister touched the bottom half of my body. It had become very hard so it was standing up.

“This is just a normal physiological reaction….”

“I’m going to say ‘good boy, good boy’ while you suck it.”

“That’s why I said….”

“If you won’t listen to me then I will scream.”

Damn it! So you’re threatening me again!

ーーーーーーーーーーーーーーーーーーーー

“Nngh… Good boy, good boy. Is it delicious?”

It was as if her soft, coaxing voice was mocking me. The two of us were in an almost embracing position as we both “worked hard” in our endeavor.

“I don’t think it’s delicious or anything.”

I answered honestly.

“Hmm~ Then what about here? Does it feel good?”

She then did the ‘good boy good boy’ rubbing motion on my standing erection on the bottom half of my body. I was embarrassed, I felt pathetic, it was the worst.

“Onii-chan, are you full?”

“Yeah. I told you from the start that I don’t want it like this.”

“You don’t need to say it like you hate it that much though.”

My little sister voiced her complaint.

“We’re done here but…. Is it alright, onii-chan?”

My little sister said so while she continued to touch my growing erection.

“Isn’t it painful?”

“I’m fine.”

After this brat returned to her room, I’d deal with it myself.

So hurry up and go…..

“Show it to me, onii-chan.”

“Huh?!”

A strange voice leaked out of me.

“I’m going to watch it so show it to me. I want to see it.”

“You stupid! You are really stupid!”

“I’ve shown you my boobs and you even sucked on it.”

“That’s because you….”

“Ah… Cough! My voice is getting louder….”

Damn it. It can’t be helped. She’s threatening me so I have no other choice. Good grief….

“Amazing. The veins are popping out… It looks completely different from what I saw in the past.”

Stop that. Don’t try to bring out the episode when we took a bath together when we were young in this kind of situation.

“It keeps on twitching about.”

I grabbed a hold of my own erection and then rubbed it up and down roughly.

“Is this the infamous…. Feeling good? Onii-chan?”

Honestly speaking, I was very aroused. I was showing her how I jerked off with my mind full of her. The thought of my cute little sister, her small breasts and the lukewarm liquid, came into my mind. I reached out my hand and there….

“Ca-Can I touch you, Natsumi?”

“………..I-If it’s just my chest.”

I slipped my hand under her shirt. It was obvious my little sister was shaking. I rubbed her chest, as if I was trying to check the shape of it and then, I could feel how hard her nipple was.

“Onii-chan, the way you’re moving your hand is so perverted…”

My little sister said so, she looked somewhat feverish. She was moving fretfully. I became even more excited at the feeling of her smooth and soft breast. My hand was moving faster and faster. I was reaching my limit soon.

“Natsumi, I’m going to come.”

“No, onii-chan’s… You’re getting even bigger. Are you going to come?”

“Natsumi….”

Unable to hold it back, I ejaculated just like that. The white liquid shot through the air and ended up splattering onto the floor.

“Spe-Sperm?! Did it feel good?”

My little sister asked, looking somewhat excited.

“Ye-Yeah.”

I’ve done it… The peculiar unpleasant feelings that hit you after you ejaculated are hitting me now.

In front of my eyes, I could see the disastrous scene, the brother-sister relationship between us that we couldn’t bring back anymore… All of those things blocked my mind from thinking correctly. I just sat there dumbfounded, left as an empty husk of my former self.

“I-I’m… I’m going to leave for now.”

My little sister then left in a haste. After she did all she liked, she left me in this state. What a heartless little sister….
