Chapter 10: My Cute Little Sister, Natsumi’s Milk?

ーーーーーーーーーーーーーーーーーーーー

My little sister was looking up to me as she asked for a kiss. Her moist eyes were swaying from side to side slowly. I held her head and her back and then slowly kissed her, putting my lips on my little sister’s soft lips.

“Mmngh… Onii-chan… Don’t stop.”

When I tried to pull my face away from her, she pulled our head back together again.

“I’m going to make you feel good while we kiss.”

She put her lips to my mouth and slid her tongue into me. My sister’s slippery tongue felt so good as she tangled our tongues together. While I was thinking about what was going on…. Suddenly I felt a rush of pleasure running through the bottom part of my abdomen.

“You’ve become this big, onii-chan.”

She whispered into my ear, sending shivers down my back. She continued whispering into my ear as she stimulated my erected thing.

“Onii-chan, you pervert.”

Accompanied with a rustling sound, my little sister licked my ear and gently bit it.

“Natsumi… Somehow, that’s… Kind of erotic….”

“Fufu, does it feel good?”

My little sister’s sweet voice and her warm breathing were trembling into my ear.

My cute little sister’s cute voice, I want to hear more voices from her.

“Can I also touch you?”

“Fufu~ Of course you can. In fact, it’s more like, why haven’t you touched me yet?”

My little sister’s breathing as she laughed, made me tremble the most.

“My skin is soft, you know. Try touching me.”

While my little sister was whispering sweet nothing into my ear, I encircled my arms around her thin waist.

I slipped my hand into her pajamas and her underclothes, fondling her there.

“I-It kind of tickles, feels weird.”

“You’re right. Your skin is so soft and smooth.”

I crawled my hand up her back, touching her over and over again as if I was trying to imprint the shape of her body.

“Mnh… Onii-chan’s hands are so big.”

I began stroking her chest with my other hand. I was touching her over her clothes so I was being a little rough but then, she stopped my hand.

“I want you to touch me directly, onii-chan. I’m going to take my clothes off, okay?”

I watched my little sister lean her body away from me slightly and as she took her clothes off. I stared at her hard as she took her pajamas off, exposing her white skin under her underclothes.

“Don’t stare at me like that. You’re making me embarrassed ….”

Looking at my little sister embarrassed like that, I became aroused.

“I want to touch you, Natsumi.”

“Wait a minute. I’m going to take the bottom part off too. Onii-chan, you take your clothes off too.”

Just like what she said, I also wanted to touch her body with my bare skin. So, I took my clothes off, leaving me half-naked.

“The bottom part too, onii-chan. Even though you’ve already become so tight like that.”

I was having a little trouble taking my pants off because of my stiff erection.

“Okay, come here.”

Clad in only her underwear with her body almost naked, my little sister invited me in. I kissed my little sister’s lips while simultaneously rubbing her breast.

“Mmnh… Onii-chan… It feels good… You can be rougher, you know.”

“But, won’t it come out?”

“I already squeezed a lot earlier so I think it’ll be fine.”

When I thought about my little sister deliberately squeezing her breast for the sake of this moment, I couldn’t stop myself from thinking how lovely she was.

“Natsumi, can I push you down?”

“Fufu~ Onii-chan, you’re so weird. Do you even need to ask?”

Without even the slightest bit of resistance, my little sister let me push her down so she was now laying on her back. I then started fondling my little sister’s breast roughly.

“Ah.. Onii-chan.. Amazing… But, it seems it’s going to come out after all.”

“It’s okay even if it’s coming out. I like it. Yours.”

“No, don’t say something like that…”

Just from her voice alone, I could feel she was getting aroused. She started wiggling her body, looking frustrated.

“Amazing, I can really feel it.”

“I’m going to touch your bottom part too.”

“You don’t need to tell me every single thing-! Nngh….”

I touched her crotch from the top of her underwear. She was so hot and wet.

“Haah… Haahhh… Onii-chan… You pervert…”

While playing with the bottom half of her body, I sucked on her breast. I sucked on them hard, as if I was trying to wrung her dry and a small amount of milk started flowing out.

“No, onii-chan…. Something… Feels weird….”

I sucked on her other breast and then I started running my hands and licked all over her body, from her belly to her hips. Her smooth white skin felt so good against my tongue.

“Ahn… Ahhn… No, my voice… I can’t hold my voice…”

“No one can hear you. Probably.”

Our secret that we absolutely couldn’t let anyone else know about. The thrill of it made me even more excited.

“Haah… Onii-chan… Do it… Properly…”

It seemed my sister shared the same sentiment as me too.

“Can I touch you directly?”

I whispered to my little sister, who seemed like she was feeling very good.

“You stuupid… I told you that you don’t need to ask for every single thing… Haah…”

I put both of my hands on her underwear and my little sister slightly lifted her hips in return.

“You’re so erotic, Natsumi.”

“Shu-Shut up.”

I took her underwear off and brought it in front of her. My little sister averted her gaze, looking embarrassed.

“Natsumi, you’re so wet.”

“Wait, aren’t you teasing me a bit too much? Onii-chan, you stupid.”

“Sorry, it’s because you’re so adorable after all.”

“Hm, I can also…”

She then grabbed my thing and started stroking it roughly.

“Ah! Crap, Natsumi, I’m going to come soon!”

“It’s your punishment for teasing me.”

I had been on the edge of bursting all this time. Even without anyone touching it, the tip was already sticky wet so this extra stimulation was really dangerous!

“Natsumi, I’m going to come!”

“Then come. I’m going to squeeze it for you too.”

After she said that, my little sister then went down on me, bringing my thing into her mouth.

“Natsumi!”

While throbbing, all of the sperm I had accumulated poured into my cute little sister’s mouth.

“You came a lot, onii-chan. Did it feel good?”

True, it was the best feeling I had ever experienced in my whole life but I didn’t want to just end it here.

“Are we done, onii-chan? You don’t have to force yourself.”

She smiled gently.

“But Natsumi, I haven’t made you feel good yet.”

That’s right. Even though we’ve gone this far already, it’s disgraceful if I end it here. At least…

“It’s fine, onii-chan. Ah! What are you doing?”

I put my face close to my little sister’s genitals and slid my tongue in.

“No, onii-chan! It’s dirty!”

I continued licking, ignoring her. Of course it was my first time actually seeing the real thing. The shape was peculiar and it gave off a sexual and lewd smell. My cute little sister who was still a bit immature but had a straightforward personality. Who would’ve thought I’d find my cute little sister’s lower part to be erotic. Right now, my little sister was twisting her body and twitching in response to the way I moved my tongue.

“Onii-chan, ah! There, feels good…”

My little sister moaned in a muffled, breathless voice. Before I realized it, I was having another erection.

“Natsumi, I want to put it in.”

I spread my little sister’s knees apart and stared at it hard.

“I can’t hold myself back anymore, Natsumi.”

Natsumi covered her face with both of her arms. It seemed she was unable to contain her embarrassment.

“Natsumi, your thing is also moving. It keeps on twitching.”

“Don’t tease me, onii-chan…”

“Natsumi, please.”

I was practically begging her now.

“………-in.”

My little sister was still covering her face with her arms. She said something in a low voice, making me unable to catch it.

“Just now….”

Before I could finish my sentence, my little sister said again.

“It’s fine. Put it in. Don’t make me say it again and again….”

My little sister said shyly.

“I’m putting it in, Natsumi.”

“Yeah, come, onii-chan.”

I spread my little sister’s leg apart then positioned myself so I was kneeling between her opening. I tried putting mine into her wet thing but it was so tightly shut, making me unable to break in.

“I can’t put it in, Natsumi.”

“Put it little by little. Yes, like that. Gently.

The tip entered my little sister. It felt slippery and warm.

“More, onii-chan. I’m fine.”

“Natsumi, I’m going to move.”

I entered mine all the way inside up to the base. My little sister was clamping down on me hard.

“Natsumi, your inside feels so amazing.”

“Onii-chan’s thing feels so tight inside. Stay still just like that for a while. You can’t move yet.”

I kissed her while we stayed connected. I kissed her lips, her face, her shoulder, I kissed her in every place I could reach.

“No-, it tickles. Onii-chan, it feels good too.”

“Natsumi, you’re so cute.”

“Mmnh… Onii-chan. It’s fine, you can move now. Slowly.”

Following her words, I started moving my hips.

“Does it hurt, Natsumi?”

“It hurts but I’m fine.”

“It feels so good, Natsumi.”

Just when I thought she was starting to loosen up a little, my little sister’s inside started tightening up on me again. Her response was beyond everything I could imagine.

“Ah! Onii-chan, ahnnn…”

Sweet voices escaped from my little sister’s lips. Our skins were touching each other. Her skin felt so smooth and a little sweaty. I could feel my little sister with my whole body.

“I love you, Natsumi. I love you.”

“I’m so happy, onii-chan. I love you too.”

Our tongues entwined together. We were lusting for each other greedily.

“Natsumi’s inside is so full of you, onii-chan.”

She said as she led my hand to touch her stomach.

“Here, this is onii-chan’s thing.”

I could feel my thing rampaging in my little sister’s stomach.

“Natsumi, I’m feeling so good right now… I think I’m going to become weird.”

“Me too. I’ve become weird already.”

Gradually, I started moving faster. I was about to reach my limit soon.

“I’m going to come, Natsumi.”

“It’s fine. You can come whenever you want.”

I wanted to come inside her just like this but I mustn’t. I could hurt Natsumi if I did that.

“You can’t come inside, onii-chan. You definitely can’t.”

“I know, Natsumi.”

“Otherwise, a baby will appear.”

I was about to pull out from Natsumi, preparing to ejaculate inside but…

“Na-Natsumi?!”

Natsumi grabbed my back using both of her legs, pressing my body down on her.

“You definitely can’t come inside! Onii-chan, you mustn’t come inside!”

“Ah! Coming, Natsumi….”

I ejaculated a lot inside my little sister.

“Natsumi, that was dangerous.”

I told her, while still hugging her tight.

“I think today should be a safe day.”

“But still.”

My little sister put her finger on my lips, silently telling me to stop talking.

“You need to put a condom on next time, okay?”

My little sister smiled.

Really, I’m really no match against her.

“I need to buy some then.”

In that moment, my thing was starting to shrink inside my little sister, making other things drip out from her.

“Onii-chan! Your semen is dripping out! Tissue! Tissue!”

“Ah! Crap, crap!”

Milk was overflowing.
