Chapter 17 – [Tip: ‘Younger Sister’ Park Seo-Hyun’s Sex Fantasy Has Sex With □□’s □□□□.]

– Oh, oppa… Whoops! Whoa, haha!

“Aren’t you touching the bottom? I told you to only touch the nipples.”

– Yes… Brother, I’m sorry! As ordered… I’m sorry…

“Thinking that I’m sucking it with my mouth, peck, peck… Peck. Touch it.”

– Ahhh… Yes, my brother… Uh… You are so young… I think it really sucks…

“Jjook, jjak, jjung jjong jjong…”

The nipples of the ‘younger sister’, which were small until just now, were rolling in my mouth and inflating their size.
And all over her chest, her immaculate skin was already stained red with the marks I left behind.

– Oh, brother! More, more… Whoops! Suck it hard… Whoops!

“Ptp, pp… Ppp. Like this?”

– Ugh, ugh! More, more!

A loud moan erupts from the other side of the phone.
And it was filled with panting breaths and wheezing.

“No way, you haven’t already wrapped it, have you?”

– Ugh… Whoops! Mo, without knowing… But, the panties are a little… It looks wet…

I put my hand down
Under the soft panties, rough hair and moist heat radiate.

“Touch it over your panties. How wet are they?”

– Wow… Yeah, wait…

‘Little sister’ tightens her thighs to prevent my hand from entering.
However, when I chin toward the phone, my eyes flashed and my legs relaxed.

“Are you wet?”

– Yes… Very, very, very messy…

“Would you like to put it under your panties?”

– Can you put it in?

“Huh… No. Just put your hand under your panties.”

– Ah, ah ah~ Oppa ah… Are you going to keep doing this?

“Should I hang up the phone if you don’t like it?”

– … It’s annoying. See you next time we meet.

“Okay, quickly.”

[Remaining time – 16 minutes]

I didn’t show it, but I’m quite scared right now.
The body of the ‘little sister’ was steadily heating up, so it seemed that the results would soon be visible.
No, it has to be shown.

– Wow… Uh, very… Wet… Ahang… I hope my brother puts it in soon…

“What do I put in?”

– That, that’s…

“What is that?”

– Oh, brother… Under it…

“So, what is it?”

I lifted one leg and got on top of the ‘sister’s boat again.
Then, with her right hand, he squeezed his cock and held it between her breasts.

– Come on, sleepy…

“What do you want your cock to be?”

– In my, bo, pussy… I wish I could put it in… !

I grabbed the cock Shin Joo-hee was looking for so desperately and shook it up and down.
‘Little sister’ tried to avoid her head to her side, but she could feel her eyes glancing at her.

“…It’s hard right now, so put your finger in my place.”

– Yes… You’ll put…

I couldn’t even hear the lewd sound of the vaginal walls wet with cum.
Only Shin Joo-hee’s voice is heard over the cell phone as she moans.

However, in the heart of the ‘little sister’ beneath me, I feel a beating that is about to explode.
To add a little bit of exaggeration, it really seemed like an earthquake had occurred.

– Wow! Brother, brother… !

Widely-! Widely-! Widely-! Widely-!

The cock, which has already grown as it grows, draws a long stream of cum from the urethra.
It stretches like a thread and falls on the ‘little sister”s chest, and she trembles in amazement.

“I, huh… Fuck you, okay?”

– Huh! Yes! Alright, bro, sleep! Awwwww !

The sound was breaking like noise because of how loud it was.
And after a while, she let out a gasp-like moan, and as if she was out of breath.

– Huh! Whoops, whoops! Whoa…

Chiyiyi profit—

And the cum that shoots out almost at the same time.
That thick and thin bodily fluid embroiders the ‘younger sister”s chest.

“Whoops! Whoops!”

As if this was unexpected, she was shaking her body and holding her breath like her friend.
I put my hand on my chest and began to spread the cum all over my body.

“Huh… Haaaaa…”

The ‘little sister’ opens her mouth wide.
I’m gasping for a while because I’m short of breath.

I slowly brought the slimy cum on my hand to my mouth.
Then, when I put my index finger into my mouth, my mouth suddenly closed with a snap.

“Huuuuu…”

It was as if he was just surprised and kept his mouth shut.
And when he opened his mouth quickly, he was restless.

“Ju-hee… Are you gone?”

– Yes… Me now… Try not to get stuck… Oh my god?

“Huh… Did you like it that much?”

– Huh… I think I will fly now…

At Shin Joo-hee’s vivid review, the ‘younger sister”s eyes shake again.
I quickly hung up on the excuse of returning the cell phone to her sister, thinking that this was enough.

“Haa… What if you bite that hard?”
“…Mi-sorry. I didn’t do that on purpose, uh, sorry anyway.”

Have you forgotten the situation of being tied up and humiliated by me? I hand the apple to my kusari first.

“Sorry, can you clean this up?”

I slipped out my hand, still wet with cum.
Eyes trembling again… However, I could see that it wasn’t a terribly disliked look.

“Since you bitten, I have to do this much.”
“…But, this is a bit…”

The eyes become more complicated.
It was so obvious from my point of view that I was worried.

Also, it was clear that I was worried about whether it was okay for us to be like this.
But, it’s been a long time since I’ve been soaked in chewing gum, and I’m still excited like that when I see me.

If so, there was only one thing that didn’t increase sexual desire in this situation.

[Tip: I deny that I feel sexual desire for my ‘son’ Park Han-sol. I justify myself that this is the education of a ‘mother’ who was concerned that her ‘son’ would fall into the wrong path.]

It was a tip of a system I saw sometime.
Because we are related as a family, our head denies this, unlike our honest body.

“Aren’t you curious?”
“…What is it?”
“Aren’t you curious about the taste of this cum juice Shin Joo-hee enjoyed?”
“…Uh, uh. I’m not curious.”

As before, I slowly brought my hand to my mouth.
‘Little sister’ shuts her mouth and stares back at me with her stocky eyes.

“Eup! Ugh!”

However, my finger touched my lips.
It was slippery and covered with algae and entered between the mouth.

“Delicious?”
“Ooh, ooh! Ooh!”

He shook his head and tried to avoid it, but the cum juice was smeared all over his face, making his face dirty.

“It’s okay. It will be delicious.”

The struggle began to subside.
The ‘sister’ realized that with her being tied up, she had nowhere to run anymore.

“Heh, heh, heh…”

Then, at the timing of her breathing, he thrusts her finger into her mouth.
Her hard teeth scratched her skin, and her soft tongue greeted me at the tips of her fingers.

“Huh, that’s right. You’re good.”

In my opinion, it looked like he was trying to push it away with his tongue, but it was just like caressing.
And he chewed his teeth carefully while looking at my eyes, but this was only giving me a suitable stimulus.

“How is it? Is it worth eating?”

The fingers were cleansed with the ‘sister’s’ saliva and tongue.
All the slippery cum was wiped away and disappeared down her throat.

“It’s very soft here, too.”

And scratching her cheeks with my hand, I also look at the ‘little sister’.

“Heheh, hee… Hee hee…”
“Is it ticklish?”
“Uh, uh uh… Sue, I can’t breathe…”

It became more relaxed.
Then he gulps down his throat and licks my fingers while his tongue rolls subtly.

I realized this instinctively.
He’s caressing my finger right now, he’s pretending not to be caressing it…

That’s why I took my finger away from my ‘younger sister’ without hesitation.

“Ah…”

The ‘little sister’ was also unconsciously moaning of regret.
This works
I thought it was unconditional.

[Remaining time – 5 minutes]

“…Would you like more?”
“…”

There was no answer.
And I closed my eyes.
It was as if he was pretending to be asleep.

So I untied my ‘sister’s hands.
I also went downstairs and untied the straps tied to my ankles.

I could see the limbs that naturally spread out to the side, and the panties that were already soaked with cum.

“…Are you really sleeping?”
“…”

It was a meaningless question.
I went through that mess a while ago, but I can’t fall asleep this soon.

Dump-

I sat comfortably next to my ‘little sister’.
And brought his hand to his mouth.

“Open your mouth a little more.”
“Ahhh…”

Little by little, my fingers disappear one after another through the mouth that slowly opens.
And when she showed up again, she was glistening with her ‘younger sister’ saliva.

“…A little louder this time.”
“Ah…”
“A little more.”
“Ah…”

I lifted one leg again.
This time, I sat with my butt on my chest, not my stomach.

“Huh!”
“It’s okay. I won’t give you strength.”
“Heh, heh… Ha ha…”

I brought the glans to the corner of my ‘sister’s mouth.
I was startled by its size and shuddered.
But, that was it.

“Huh… Clean… Haaa…”

Stick your tongue out
And I didn’t even order it, but I roll my tongue while licking the area around the urethra.
Again, as the tongue touched, the urethra naturally opened, and the inside was licked and sucked, swallowing the cum.

It was a bit clumsy, but that made me more excited.
My heart skipped a beat when I realized that the person sucking my cock in my mouth was my ‘sister’.

“…Delicious?”
“Jjwup, jjwup… Haljjak, gulp.”

Although no answer was heard, there was no need to hear either.

“Huh… It’s going to be cold, ha ha, it’s going to be cheap…”

Tongue moves faster.
The mouth opens even more.

Then, with a squeaking sound, more cum than before flowed into the ‘little sister”s mouth.

“Gulp, gulp, gulp! Cough! Cough! Gulp.”

A huge cough burst out, as if he had heard of the case, and he immediately put his cock back in his mouth and swallowed the cum.

“Haaaaa”

It was a sigh of relief that came from deep within.
Of course, saying that it was good wasn’t empty, but now I’m a little more relieved by the system message.
