1 Aiko X Daiki

Hello, my name is Daiki.

My parents died in a car accident a few months after I was born, so I didn't know them.

I spent my first years of life in an orphanage until I was adopted by my current family.

My present family is ordinary. I have a father, a mother, and a beautiful little sister.

It has been fifteen years since I was adopted, and I am now eighteen years old. My younger sister, Aiko, is the same age as me.

She's only a few days younger than me, so I'm the older brother.

"Daiki!"

My mother, who is helping my father prepare for the camp, calls me.

"Tell me!"

"Take the watermelon and cool it in the river."

"Okay, I'm coming."

Dad had brought a watermelon from home so that we can enjoy it when we arrived at the camp.

It's lucky to have a river next to the campsite, as we can swim and have fun in it.

"Onii-chan..."

The one who calls me now is Aiko, my younger sister. She's a total beauty, and the number of pursuers she has is endless.

But she's still single, and there's not a single rumor about her being around any guy.

The reason for this is that she always rejects them coldly. Aiko treats all boys with a cold and indifferent attitude.

Well, not all, since she behaves like a little girl when she's with me.

"Where are you going?"

Aiko wears a thin, transparent white dress, which shows off the white bikini she's wearing.

"To cool this watermelon in the river."

"I'm coming with you!"

She clings tightly to my arm.

"But you might get wet."

"It's okay, look!"

Aiko lifts up her dress and shows me her bikini.

How erotic...

"This is why it'll be fine if I get wet."

She smiles at me.

I've...

I know that smile well.

There's a reason why my sister treats guys with a cold attitude, and that's because...

"Wet me well, Onii-chan."

"Don't worry, I'll make sure you get wet."

.....

Slurp! Slurp!

We're at the river.

I've sat on a rock that juts out at the edge of it. Aiko is on all fours in front of me, sucking my cock while making lewd sounds.

Slurp! Slurp!

"Ah, keep it up."

Slurp! Slurp!

Aiko slowly but surely raises and lowers her head.

Sigh... I remember, years ago, when she gave me her first blow job... She was so clumsy and shy back then.

"Watch out, Onii-chan. Especially for mom and dad. "

She says to me as she keeps sucking my dick.

"Mng!"

What a shiver of pleasure she just gave me. She's using her tongue to get to all the spots on my dick.

"I know all Onii-chan's pleasure points, I learned them to give you the most pleasure possible."

Don't look at me with those eyes. God, it's good that she's become a blowjob expert.

Slurp! Slurp!

"Keep going, I'm about to cum."

Aiko's eyes glow, and she increases the rate at which she moves her head.

Wow, I wasn't expecting this change of pace.

I grab her head and stick my dick down her throat.

"I'm cumming!"

Gulp!

Aiko swallows all my semen. Her face shows an intoxicated expression.

"Aah!! Onii-chan's semen..."

Aiko rolls her tongue over her lips, where there were still small drops of semen.

"There's still a while left until the watermelon cools down, Aiko."

"Yes, Onii-chan..."

Aiko turns around and shows me her thong. This can't be, this cloth is obstructing my work.

My dick, which barely discharged a few moments ago, is hard and shaking. It seems that my younger brother's desire not to penetrate Aiko is no less than mine.

I pull down Aiko's panties, and there I see the pussy I've fucked so many times.

"I'm going to stick it in."

I stick my whole dick in, without any mercy. I haven't even done the foreplay with her pussy...

"AAAAHN!"

... And that's because Aiko is a pervert. Her pussy was already wet since she started sucking my dick.

Pah! Pah!

With a piston motion, I took my dick in and out countless times.

"MMM! Feels good!"

"Ah! Ah!"

I feel good too, Aiko. Your pussy's as tight as ever, doesn't look like I've fucked it a hundred times.

"Mom... I'm sorry!"

What's Aiko saying now?

"We come here... Ahn!... To enjoy... time together... as a family..."

I grab Aiko's big breasts and squeeze her nipples. Her tits are two big pieces of meat, and my passion is to play with them.

"Onii-chan!"

Pah! Pah!

"We came here... to be like a family... but..."

Pah! Pah!

"I'm here with onii-chan..."

Aiko's vagina gets even narrower. She's threatening to suck me in.

"Again...!"

Aiko turns to look at me, I swear I can see hearts in her eyes. Her mouth is half open, and her tongue comes out, I know what she's asking me.

I bring my face closer to hers and insert my tongue into hers.

"MM!"

"MM!"

Our mouths separate, and I speed up the pace of my piston movement.

Pah! Pah! Pah!

"Onii-chan! Onii-chan! Faster, harder! Give me more!"

"I'm cumming!"

"Me too onii-chan, me too!"

Pah! Pah!

"Let it all inside, Onii-chan! I want to have your child inside me!"

"If you ask me like this... I can't refuse..."

Pah.

"Hiiieeec!"

Aiko's vagina squeezes me harder than ever, and I let out all my semen inside.

"Again, Mom... I've made love with Onii-chan again."

"Aiko, kiss me."

I command her.

"Yes, onii-chan..."

Mmm!

Our tongues connect once again. Both fight, seeking to absorb as much saliva as possible from the inside of the other person's mouth.

"Onii-chan..."

Aiko separates from me.

"Yes?"

"I want to change my position."

At Aiko's request, I nod without hesitation.

.............

"Ah!! Ah!!"

I'm lying on the floor, and Aiko's on top of me. She's in cowgirl mode as she rides on my dick.

I'm playing with her breasts, which I love. It's my number one hobby.

"We have to go back... Ahn!... Mom and Dad..."

Even though she says that, she keeps jumping on my dick. Her face is full of ecstasy, and she just asks for more and more love.

"We're here to enjoy time together as a family, aren't we? Aren't we enjoying time together?"

I say to her as I lift my hips. Our rhythms are synchronized, I raise my hips at the same pace as she lowers hers. Thus, our pleasure is doubled.

"YE-YEAH!"

I don't know if you're saying that because of the question I asked you, or because of the pleasure you're feeling.

I've had enough of playing with her tits, I think I'll suck on her nipples for now.

"No, no, no! Ah! AAAAH!"

Aiko's right nipple is one of her sensitive spots. If I bite it with just the right amount of force, she comes instantly.

"Don't suck it! No! NO!"

Her vagina's really squeezing me... If this keeps up, I'm going to cum again.

"I'm cumming-!"

Aiko's vagina is getting a lot tighter.

"Mng!"

I seal her mouth with my lips to keep her from screaming at the top of her lungs since it looks like that's what she was going to do.

"Let's change positions one more time, Aiko."

"Yes, onii-chan!"

Now let's go to my favorite position, the missionary's.

"I'm going to put her..."

"Don't hold back, Onii-chan."

I won't, Aiko.

I'm putting her in slowly, tasting all of Aiko's insides. My dick goes in smoothly, due to the large amount of Aiko's love juice mixture and my semen that resides in her pussy.

Pah!

Pah! Pah!

"Ahn!"

Pah! Pah! Pah!

Slowly, I'm accelerating my piston movement.

Pah! Pah! Pah!

With one hand, I grab Aiko's tit, while I stick one finger from the other into her mouth.

Aiko sucks my finger desperately with her tongue. This side of her is too erotic.

My movements speed up once more.

Pah! Pah! Pah!

"I'm cumming again!"

Pah! Pah!

"Don't be... so rude! No! No!"

Pah! Pah!

"Oh, God! Oh, God!"

Pah! Pah! Pah!

"I'm cumming... again!!!"

Pah!

Once again, I let my semen out into my sister's vagina.

She said she wanted my baby, didn't she?

So that's what I'm going to do, today Aiko is going to get pregnant.

...

Slurp! Slurp!

After the last run, Aiko and I took a little rest to recover from the wild exercise.

But it wasn't long before Aiko looked for my dick one more time, and started sucking it under the pretext of "cleaning it up".

And here we are again. Me lying on the floor while Aiko gives me a blow job.

"You're hard again!"

Of course, who wouldn't get hard?

"You're the one who makes me hard, Aiko..."

A couple of sweet words are never wrong.

"Onii-chan..."

Aiko looks at me, her face is flushed.

"Mmn!"

A surprise attack on her lips and our positions switchback.

"Onii-chan?"

"They say a woman gets pregnant if the man runs inside her three times. I've only come twice, there's still one left."

Aiko doesn't seem to be able to stand my intense gaze that runs over her voluptuous body as she looks away while her face blushes to her ears.

"If onii-chan says so, then you have to come once more. Y..."

"And?"

I bothered her a little to see her cute reactions.

"...don't let a drop go to waste."

Pah!

"Ahhh!"

Pah! Pah!

The sound of flesh on flesh was clearly reaching my ears. Aiko's ecstatic face lit up and accelerated at the same time. I couldn't stop fucking her pussy.

"I'm cumming!"

Pah! Pah! Pah!

"Onii-chan! I'm cumming, Onii-chan!"

Once, twice, five times...

"Ah!!"

Pah! Pah!

"I'm cumming!"

I went from sucking her left nipple to sucking her right one, followed by kissing her mouth with passion.

Pah!

Without stopping the rhythm of my piston movement.

"Onii-chaaaaan!"

I had already lost track of how many times Aiko had cum when I finally reached my limit.

"Here it comes, Aiko."

"Yes! Cum, Onii-chan! Cum inside me!"

Pah!

Aiko wrapped her legs around my back and closed them tightly. I almost couldn't move, but I didn't care anymore since I was ejaculating inside her.

"Onii-chan..."

"I love you, Aiko."

I caressed her beautiful face with her hand.

"I love you too, onii-chan."

Our faces came closer once more, and we kissed with passion.

....

After our family exercise, Aiko and I returned to the camp our parents had set up.

"Ah, onii-chan, you left your watermelon in the river!"

"Shit, I'm going to get it."

"I'll go with you. After all, I haven't gotten too wet yet."
