Chapter 75 – What Not to Do (1) [Additional Scene]

·

The next day, my brother and I woke up really late, probably because we were tired.
When I got out of bed and opened my eyes, lunch had already passed, and my brother was still sleeping next to me.

“Ah ah ah ah ah…”

As soon as I woke up from my brother’s bed, I saw my face and immediately covered my face with both hands.
I must have washed and slept… I didn’t even dry my hair properly, and I slept again with sweat all over my body, so the dirty smell was still full on the bed.

Having regained my reason belatedly, I regretted not having properly stopped my brother last night.
And, at the same time, I thought that my younger brother was a little bit, but he didn’t seem to be able to tolerate it well.
Normally, if you ask me to stop or ask me to stop, I stop right away… It’s very hard on her sister, and there’s nothing wrong with her brother not being patient, but I was worried even though I thought it might be…

We’ll have to sleep in the same bed for a while… Realizing that I might end up having sex with my brother if I do this wrong, I looked down at my younger brother who was still asleep, vowing to be more careful in the future.

My younger brother covers me with a blanket so I don’t get cold while I’m asleep, and puts a towel on the bed… I was asleep with my arms stretched out towards me.
It was like giving me an arm pillow… I couldn’t remember why it was like this.
She probably slept hugging me while I was asleep.

“Whoa… Haaa… Seriously, what should I do…”

Since we’re older sister and younger brother, we could sleep in the same bed, but… Also, this was a bit embarrassing.
I sat on the bed, covered my face with both hands, washed my face dry, and got up thinking that I should take a shower first.

“Uh?”
“… Woke up?”

But then, suddenly, my brother grabbed my wrist as I was trying to get up, and rubbed his eyes in a slightly subdued voice.
It was already past lunchtime, so my younger brother was also waking up, and it seemed like I woke up with just a quick glance at my body.

“Hey, did you sleep well? Oh… !”
“Whoa… Did you sleep well, sister?”

As soon as her brother woke up, he pulled me and threw me back on the bed, as if he was trying to keep me from running away.
I was stunned and lay there with her arm held by her brother, my feet clasped in nervousness, while her brother climbed on top of me and ran a hand through her tousled hair.

“Tongue.”
“Yes… ?”

I didn’t understand what my sister said, so I asked again, and her sister looked down at me with strangely strange eyes, as if looking at prey, and told me in more detail.

“Put out your tongue.”
“Tongue, tongue?”
“Hurry.”

My heart was pounding at the bewildered yet coercive attitude of my younger brother, so I immediately stuck out my tongue.
Then my younger brother immediately started sucking on my tongue.
As soon as I wake up… I was surprised to see my brother and I entwining our tongues with each other while floating on the sea, but my head went blank and I became more and more calm.

“Shit… C’mon, side… Ha… The tongue, why… ?”
“… I want to do it as soon as I wake up.”
“Shit… Jjook… Uh, that can’t be… From morning… Ah, jjuup, side…”
“Ha… It’s not morning.”

My younger brother seemed to want to continue to do it, as if it was very pleasant to touch each other’s tongue with me.
I was very embarrassed, so I sucked my brother’s tongue and asked him to stop… My brother didn’t seem to want to stop at all.
As my brother said, it wasn’t morning, but I was very concerned about doing this as soon as I woke up. I was worried that her mouth might smell… My brother’s tongue was instantly filled with sticky and dirty saliva, and I unknowingly made him gulp, gulp, and swallow, but I didn’t know that my tongue might feel different to him.

“Shit… Jjook… Haaa… Mr., Wash up and come… Wash up and come…”
“… Can I do more after washing up?”

I thought I was in danger too, and I wanted to say no because I was a little worried that my younger sister’s eyes seemed to be turning into an animal for some reason… I thought her brother would never let me go if I said that, so I quietly nodded her head.
Then my brother let me go and got up from the bed and followed me to the shower room.

“Oh, no, I’m alone…”
“Can’t we wash together?”
“Restroom! I’m going to go to the bathroom too!”

When I said it with a blush on my face, my sister scratched her head as if she was apologetic and slipped away, and I sighed and went into the shower to do my errands and start to wash really clean.
I did it once when I started brushing my teeth, and after washing it all, I used the dishwasher that my brother had hidden in an unknown place, washed it from the inside out, and dried my hair properly before I came out of the shower.

“Haaa… Mr., Please wash it.”
“I’ll be out in 10 minutes.”
“Yes… ? No! Please wash it properly!”
“… 15 minutes. That way I can wash properly.”

As my brother said that and went into the shower room, I suddenly remembered what I had said when seniors gathered who had served in the military.
Seniors used to say that they came out of the shower cleanly in 5 minutes, and since men don’t have many places to pay attention to when washing like women, I thought it might be.

For some reason, I had a hunch that when my sister came out of the shower, she would want to do something again… I thought about whether I should wear it or not because I would get wet again.
In the end, I cleaned my brother’s room without wearing anything, changed the sweaty bedsheets, threw away all the condom wrappers properly, and changed the duvet.

“Whoa…”

When the cleaning was finished, her sister came out of the shower, and her sister came into the room, wiping her hair with a towel, wearing nothing, as expected.
My sister must have washed properly in that short time, and her face became clean and her body… It’s clean.
In particular, the hair there, which had been tangled because it spewed out a lot of pouting and transparent water whenever I felt it the previous day, was very clean.
While examining my brother’s body, I blushed because I felt like I was too perverted to look at these things in detail.
Her brother’s was already big and stood stiffly, and as soon as he entered her room, he hugged me as if it were natural to do so, and brought her face close to her, tilting her head upward.

“Oh… Jjook… Not to sleep… Jjook, side… Wait a minute, yo…”

I really felt like my body wasn’t listening. With both hands, she pushed her sister’s chest and tried to fall off, but her two feet worked hard, standing on tiptoe, helping her little brother comfortably play with my tongue.

“Shit… Jjwup, jjwup… Ha… I’m not going to sleep… Wait… Ha, ha, jjook…”

My sister put it right under her breasts and rubbed her cock tightly, and I tilted her head back and sucked the tongue that was sticking out for a long time.

“Ha-ha, ha-ha, ha-ha… Ha…”

I tried to calm my rapid breathing, as if I had just run, and I completely got out of my brother’s arms and went to the bed and sat down.
Then, banging the side of the bed with my hand to make a bang, bang, I told my brother.

“Oh, please sit down.”

My younger brother listened to my words and suddenly looked down as if asking why, but nodded and sat down next to me. I talked.

“Excuse me… Ah, for the next few days… Are you going to sleep together?”
“… Yes?”
“We slept together yesterday, but… I have some concerns.”

My face heated up as I remembered what had happened the night before, and I asked anxiously as I looked at my younger brother, who was growing up even though it was daytime.

“Three, sex… Want to do?”
“Yes?”
“So… Unbearable, hard… Will you?”

My brother listened to me and stayed silent for a while as if he was in trouble for some reason… She said honestly with a nod of her head.

“Yes, I want to…”
“Uh, uh… Yes, me too… It’s all natural. Sex with each other… I know you want to, but you have to sleep in the same bed…”

While going on a trip to Hong Kong and talking honestly with her sister, it was a story that I could honestly say because my sister and I already confessed that it was difficult because we wanted to have sex with each other.
I was embarrassed to say it, but I thought that if I continued like this, I would have sex with my sister, so I talked really hard while blushing and avoiding her gaze.

“Me too… Because I want to have sex… We have to watch out for each other. I’ll sleep in the same bed all the time… Probably, you will be stimulated with a lot of sexual desire…”
“Hmm… Right.”
“Yesterday was very difficult to bear… ? That’s why I’m going to go to the inside like that…”
“Uh… Yes.”
“Gwa, it’s okay! My sister can’t stand it either, so I’m talking about it now…”

I saw my sister’s cock getting stiffer and stood still, so I said it all in a hurry, fearing that her sister would be ashamed to get excited by saying these things to me.

“Therefore… Hey, I think we should be a little more careful with each other… Thank you for your patience… But yesterday, I’m talking about it because it seemed a bit unbearable.”
“It’s true that it’s hard to bear…”
“I-I can’t stand it either… If you do this really wrong, I’ll have sex…”

Even though I knew in my head that I shouldn’t, it was very difficult because I felt that my body kept giving permission to my younger sister without permission, and rather begging me to do more.
I was really worried when I said it, and for some reason my sister suddenly covered her mouth with one hand… Maybe she was just thinking, she covered her mouth and spoke quietly.

“Why do you think it becomes unbearable?”

I listened to my brother’s words and thought about it… He spoke very honestly.

“… I feel so good… I think so.”
“… Are you saying that you feel better than before and now you can’t stand it?”
“Yes, yes… It was difficult to scratch only the front, but now the inside too… I do it once, but… Thank you for always being patient… I think my sister keeps making mistakes… It’s not like I’m the only one who can’t stand it… You have to be careful…”

My sister must have recognized that I was serious, so she covered her mouth and quietly lowered her head and thought about her.

“… How can I be careful?”
“That…”

And after a while, what my brother said while looking down at me, I was speechless and couldn’t answer anything.
How can I be careful… Actually, the best way was to not let them put any more, but… If I did that, my sister would be very sad, and I was so sorry that I didn’t want to do it either.
I had endured well before, but I was wondering why yesterday was so difficult to endure, and in my head, I recalled what happened yesterday and what happened before, comparing what was different.

“Oh…”

Thinking about it so well… In really unbearable moments, my sister’s things were always stimulating a very weak spot.
When it was a simple stimulus, or when the stimulus was less, my brother and I tolerated it well… I thought that we could not help but want to have sex because we stimulated each other’s instinctive desire by inserting it deeply and rubbing the inside.

“I-how about this… ? Inside… You’ll want to put in a little bit to satisfy your cravings, so it’s okay to put in… I will teach you what not to do.”
“Yes?”

I started telling my brother what I thought.

“Therefore… In the end, it became unbearable because the stimulation of each other became too strong… Is it like that? I put up with it when I was in Hong Kong, but that was probably because we slept in the same bed… I think he’s doing this temporarily, but my sister is simply… I feel so good… That’s why I feel so… It’s tough.”
“Uh… Yes, that… That’s right.”
“Therefore… I’ll teach you where you’re weak inside, sister… I will teach you where to be careful… Then, okay… Wouldn’t it?”

The more I talked about it, the more I thought it was a good way as my brother had been patient and careful until now.
If you stimulated a weak spot, I reacted too much, and I stimulated my sister’s, and then I felt it more and more, creating a vicious cycle where I became more and more unbearable.

My younger sister gets more and more intolerant of the stimulation, and I did too… You just had to be careful in dangerous places from the beginning.
My sister also listened to what I said and nodded her head to see if she thought it was right.

“… It sounds like you’re right, but… How are you going to teach me?”
“Yes?”

It seemed right that it was a good idea, but after listening to my brother, it was like that too.
I also didn’t know where I was sensitive and where I was weak… In particular, there were a lot of things I didn’t know about my younger brother because they easily reached places I had never stimulated before.
What can I do to let my brother know where I am weak… While I was worried, my sister raised her finger as if there was a way, and asked if it would be okay to do this.

“… I’ll touch it, so why don’t you tell me if it doesn’t work for you?”

I heard what my brother said… It really seemed like there was no other way.

“Yes, yes…Okay, yo…”

I thought about it for a while and finally nodded and said, and my younger brother put his hand on my shoulder… He put me very carefully on the bed.
Then he climbed on top of me… I put her glans up against my mouth and gently scratched the clit, forcing her tongue to stick out and entangle it.

“Shit… Jjook… Ha… Ha… Jjook… I think my tongue will be pulled out…”

As if my sister was getting ready, I scratched her mouth with the glans until I heard a thud thud thu boo as I wrapped my tongue around her mouth, and I became very shy and said,
Really, the root of my tongue hurt a little because I was sucked in too much and let my sister do whatever she wanted.
However, apart from being sick, I felt very strange about entwining my tongue with my younger brother, so I soon got wet at the entrance.
Every time my brother’s things were rubbed together, with a clicking sound, the entrance, which sometimes let only the front part in, became very hot, so he was kissing the glans at will.

My sister got off the top of me, and before I knew it, she spread her legs apart and sat comfortably between my legs, which had become lying down, looking down at me.
After that, I raised my neatly arranged fingers and carefully touched the entrance… I put my finger inside the wet.

“Huh… Haha…”

As it is, her sister began to touch every corner of the wrinkles inside me with her fingers.
