Chapter 186 – Betting ○○ With My Sister

Humans get energy through food.
And the leftovers of the food we ate are collected in the rectum and discharged through the anus.
Such an activity is called defecation.

Defecation is a sacred act.
It is in charge of an important part that should not be left out in human life support activities.

Constipation or diarrhea that causes problems with bowel movements can also be a signal that something is wrong with your health.
A healthy bowel movement is good for your body and good for your mental health.
This is why we feel a sense similar to pleasure when we see stool for the first time in a while, or when we have endured it for a long time.
If you feel uncomfortable when you look at the stool, a person will hate to see the stool, and that will adversely affect your health.

It can be seen that sexual activity is in line with the reason why it feels good.
Humans are said to have evolved to make sexual intercourse feel good in order to maintain the species.
If sex is all pain, who’s going to spend their energy trying to have sex and puppies?

In other words, defecation is sex.
End of proof.

“… Hey, Seon-Hoo Jin. It looks like it’s going to be hard, but why don’t you give up?”

The reason I’m having this kind of delusion.
It was because of a ‘certain bet’ I made with my sister.

“My sister. You better go to the bathroom before you get tired of your panties?”
“Huh, I absolutely hate it. I don’t want to die, I’d rather just wrap it up like this and kill you… Ugh… !”

My older sister bites her lip as if the signal came while she was talking.
A drop of sweat was sliding down his temple.

“Whoa…”

My sister seemed to be having a hard time too, but in fact, I wasn’t fine inside either.
We both had two enemas injected into our anus.

The battle was in full swing in my stomach.

Chinese troops rushing down.
And to prevent this, the Nakdong River defense line was spread out.

This is the last bastion.
Crossing this line is the end. It ends up being red unified.

I decided to martyr my country while looking at the terrifying black adult products on one side of the bed.

* * *

About 30 minutes before I struggled with the storm in my stomach.
After watching episodes 3 and 4 of ‘Flower Dangna’ in the living room with my sister, I proposed to her in passing.

“Sister. Shall we try that?”
“What is that?”

The atmosphere was good.
It is possible now. No, I thought it was now or never.

“I mean anal.”

After talking to my sister about anal sex before, I did my own research.
Theory mastered. All that remains is practice.

The question was whether my sister would accept it.

“Okay. Good.”

My sister-in-law accepted the offer so meekly that I was surprised.
In the first place, the story of anal was brought up by my sister, and the tools were also ordered by my sister.
From the beginning, it must be assumed that she was interested in it.

“There are conditions instead.”
“Condition?”
“Follow me.”

It was strange that my sister accepted it meekly.
I know the horror of getting your butt robbed too. So, I was willing to accept certain conditions.

However, the condition that the older sister offered was not quite so.

“What what what… Hey, is that it?”

I followed into my sister’s room and couldn’t help but be astonished.
My older sister smiled wickedly and put it on her crotch in the form of a belt.
Then, between her older sister’s legs, something ugly that shouldn’t exist for a woman appeared.

“You don’t know what?”

Know what it is
Strap-on dildo. Or what is called a penis band.
It is an object used when women have sex with each other or when women fuck men.

However, it was brutal. Even if it was nasty, it was too nasty.
The jet-black model was too big to be called a cock.
It was enormous, thick, and crude.
It was an iron ingot.

“Sister… What are you going to do with it?”
“What? I’m going to fuck you.”

My sister responded by bouncing her prosthetic cock playfully.
I trembled with fear, as if a weapon had been put to my throat.

“… No. I won’t.”
“What? You said do it.”
“I said I would fuck you, I never said I would.”
“It’s okay to hit it once in a while.”
“What happens?!”

It’s not like sharing a side of beans, but what do you mean by sharing it?

First of all, the size doesn’t make sense.
The thickness was almost the thickness of a wrist, and the length seemed to be 30 cm.

Are you trying to put something like that in the first place?
It seemed that he could see the future of suffering from anal disease for the rest of his life.
Do you think that just because you put my cock in from the start, does a man think that it is possible for a man to do that?

“Anyway, don’t. Pretend there was no anal talk.”

I’d be lying if I said I wasn’t interested in anal sex.
However, I am fully satisfied with my sex life now. It’s not that I’m being courted enough to want to do it as an anal even while dedicating my youth film.
So I firmly refused and tried to leave.

“Are you really going to be okay? Then, can I ask someone else too?”
“Ugh…”

I couldn’t help but stop at my sister’s words that seemed to be testing me.

I have no right to meddle in my sister’s free sex life.
Because I’m doing my best.

But I didn’t like it.
My sister with another man… I don’t even want to think about that.

My sister must have thrown the bait knowing my psychology, but I had no choice but to bite the bait.

“… Sister. Then let’s do this.”

–That’s how my sister and I came to make this ridiculous bet.

The content of the bet is to inject enemas into each other’s anus and see who will last longer.
Whoever endures longer wins, and whoever goes to the bathroom first loses.

It was a death game in which the winner beat the loser.

“Does this really make you an enema?”
“Would you like to sell it?”

I took out an enema from my sister’s box of adult products.
The enema, which was packaged individually in a small paper box, was only 30mL in size.

My older sister and I are the first directors.
Can something this small really work? I couldn’t help but think.

“Just do weird things.”
“Because I know.”

At first, each of them tried to insert it directly into their own buttocks.
Then, according to my sister’s insistence that I could manipulate it, we decided to give each other enemas.

I think it’s already strange at the point of giving each other enemas.
What is weird by older sister standards? Maybe I should put it in before the enema?

“Eww…”

My sister lowers her panties, lies on her stomach, and sticks out her butt.
We got used to showing each other naked, but the unfamiliar situation of injecting something into the anus was bringing shame.

It is not easy to see a sister who is shy.
I pretended to open her enema and calmly admired her.
Her ass, which had risen in fat to the point of appetizing, the deep pink chrysanthemum flowers blooming between them, and even the centerline of her pussy poking out from her panties hidden under it.

“What are you doing! Do it faster!”

My anus twitched whenever my sister spoke.
It was as if her ass hole was talking.

“Huh. Sister, relax her ass.”
“Eww…”

Thinking that I might get hit if I waited longer, I immediately injected the enema.
Just open the cap, insert the tip into the anus, and squeeze out the contents.

“How is it? Do you feel it?”
“You put it in right? I’m not sure?”

It was my turn next.
Just like her older sister, she stuck out her butt and lay down.

“Heh. It’s a cute X-hole. I’ll wait for you, because my older sister will fuck her in her mess.”

My older sister stroked my anus with her index finger and said grossly.

A little creepy.
Even if it’s to protect the cute X-hole, you must never lose.

“Sister. Don’t say anything weird and do it quickly.”

That’s what I said, but I didn’t mind taking it a little slower.
Because the more time I take, the better I am.

“Okay then put it in. Lose strength.”

As if giving an injection, my sister put the enema into my buttock while slapping her butt for no reason.

“How about you? How do you feel?”
“No. Are you okay?”
“Right?”

Like my sister said, I didn’t feel anything different.

“Hey, don’t do that, let’s add one more.”
“Hmm…”

My older sister and I have a healthy constitution, so it might be that the medicine doesn’t work well for me.
Thinking so, I accepted my sister’s additional offer.

──It took less than three minutes to regret that choice.

“Ugh!”

In less than three minutes, an earthquake, a volcanic eruption, and a tornado occurred simultaneously in my stomach.
In a word, it was fucked up.

“Kuk!”

And it was the same with my sister.
My older sister, who had been relaxed until just a moment ago, pressed her lower stomach and crouched down.

“Sister, do you look tired?”
“You, indeed.”

My sister and I had forced smiles.

Whoever goes to the bathroom first loses.
That means you win if you make your opponent give up first.

So how can you make your opponent give up?
No matter how much I put up with it, I just need to make it feel like it will explode before the other person does.
In other words, I acted as if nothing happened.

… So, 5 minutes passed.

“Whoop, whoop,”

My sister takes a deep breath as if impatient.
But I acted expressionlessly, pretending to be as normal as possible.

“… Hey, honestly, isn’t it hard?”
“No. Not really. There was a signal earlier, but it seems to have gone in now.”

It’s a lie.
My stomach was fighting a desperate battle to protect the Nakdong River defense line.

Kururureung.

Another bombardment just fell.
… It could be really dangerous now.

“… Hey. After Jinseon. Why don’t you make it a draw instead?”
“…”

I didn’t answer.
No. Couldn’t answer.
The moment I opened my mouth, it seemed as if my anus would also open.

“Seonhu. Look at my sister huh? My sister will buy you a car. Bentley. You said you wanted a Bentley.”

No.
Not even a Bentley, but a Bugatti.
My anus is irreplaceable even with a fighter.

“Hey, Jinseonhu! Do you really want to come out like this?”

Looking at the words coming out, it seems that noona still has time to spare.
I crossed my legs and sat cross-legged.
Then I closed my eyes and started the Buddhist zazen.
I felt like I could enter Nirvana now.

“Kuh… Ugh…”

I hear my sister’s subtle moans.
Words seemed to come out now.

How much time has passed
7 minutes? 8 minutes?
Anyway, the end isn’t far away.
A little bit. A little further… !

“──Ugh!!”

Come!

After making a painful noise, my sister got up in a hurry and ran to the bathroom attached to the room.
… Leaving only a subtle scent that I can’t bear to say.

“Heh… It’s my victory.”

But I couldn’t help but laugh.
From my sister’s room to the bathroom in the living room, a hellish march was waiting for me.

“… Kut.”

It looked like it would explode the moment it stood up.
Unable to stand on my own two feet, I had to crawl to the bathroom on all fours.

But did they say patience is bitter and fruit is sweet?
After that arduous march, I was able to experience the most ecstatic bowel movement in the world.
Besides, after this, it’s time for my sister’s reward.
The fruit was the sweetest of all.
