Chapter 11 – You Can’t Do This to Your Sister (1) [Modify]

“… Yes?”

My younger brother sounded very embarrassed at my words.
I was thinking about something while taking a shower, so I honestly started telling my younger brother what I thought, thinking it might be a good idea.

“Each other masturbation caught… That, in fact, is very embarrassing… Since we live together, I don’t know if something like this will happen again in the future. If you set a time for each other and do it at that time, you can go unnoticed and be cared for, right? ?”
“Uh? That, that… Still.”
“And… Actually, uh, since we both use masturbation devices… I feel good, I don’t even know who came in… Besides, I wear earphones… It’s embarrassing, but you won’t notice even if you’re in a situation where you might be caught…”
“No, that’s, but, that’s…”

Maybe he felt that I was right, but he kept his mouth shut.
Actually, for me, witnessing my sister masturbating… I think it’s a little bit okay, but I thought that showing my masturbation was vulgar masturbation that didn’t fit the caring and innocent image that my sister thought of, so I was so embarrassed that I didn’t want to be caught.

“Yeah, so let’s set our masturbation time… Since we live together, I think we need it.”

At my words, my younger brother didn’t say anything, as if he eventually agreed, and I asked him to set a masturbation time first.
And the younger sister hesitated, but she finally said the time of dawn… I said that sleeping that late is not good for the body, so let’s do it around 11 p.M.
And after that, I decided to do it during lunch time, when my younger brother went to school… We promised to take care of each other that time.

“Then should I call in advance if I have to come over for lunch?”
“Yes, yes…”

My younger brother obediently followed my suggestion even though he was hesitant about whether there was something that bothered him.
I felt better thinking that I wouldn’t have to make any mistakes anymore, so I rubbed my younger brother’s shoulder to apologize for the mistakes he made so far, then I remembered that I didn’t give him tutoring today, so I taught him to study until I went to bed.

I have a bit of a bad habit, and after my younger brother takes an exam, I keep sitting at my desk while giving him grades, but strangely, except for my younger brother looking up at me slightly from below, he was restless. I was able to sleep well.

No… Actually, my brother… That, the moment when I was cheap suddenly came into my mind.
I keep getting a glimpse of its shape and its swaying… I’m tired of sleeping.
Except for those two things, I was still able to sleep very well.

．

For a while after that, I thought it was a really good idea to set a mutual masturbation time.
There was nothing to be discovered, and since we set aside time for each other, we were able to take care of each other, so we didn’t see each other by mistake.
By the time it was late at night, I would go to bed first and lay down, and my sister would let me masturbate freely.
Therefore… I realized that the sound of water that I could sometimes hear every night was the sound of washing after masturbating.

From then on, for some reason, when it was time for my younger brother to masturbate, I couldn’t sleep.
I imagined how long I had masturbated because I thought of the sound of water in the bathroom without even realizing it, and I took out a big thing and washed it… The image of him shaking his back deeply in the masturbation device kept coming to mind.

More than anything, if you really pay attention, sometimes… I heard a sticky squeak… Even when her mother used it as a sex room, she cared that she heard dirty sounds, but she didn’t even think about it and was surprised.
I thought I could hear my younger brother masturbating, and besides, it sounded very naughty… I was troubled because I kept thinking about the scene I had seen.
The number of masturbation, which had been reduced since her brother came, changed to once a day from this point on.
I do it every day, once a month, even on sensitive days, I’m full of thoughts of wanting to masturbate…

For some reason, my brother’s trash can also semen, it seems that something is getting heavier, her head became strange.
She tries not to smell it, but she keeps sniffing it… At some point in my younger brother’s room, I always felt that it was my younger brother’s smell, but it stopped smelling like a man.
I was ashamed of it and kept doing it and regretting it.

“Haah … Ha … Huh, reaction, huh …”

And yet… When I was masturbating in my younger brother’s room, I couldn’t forget the throbbing feeling, so I committed it… Should I say it’s a thrill? The thought of doing it before my younger brother comes and the thought of doing it in a place where I shouldn’t have overlapped, so I kept feeling it too much, and even if I did it in my room, I felt it was a little lacking… I went to my brother’s room.

“Ah, ah, ah, ah, haah, haaang~ haaang~ haa, haa, whooooo…”

Lie down as if supporting the floor with all four feet, as if folding your body a lot? Do… As I rocked my hips up and down to make a splat sound, a small puddle of water formed in my younger brother’s room, and I felt pleasantly surprised by his younger brother’s rich, sweet, yet manly scent… I feel like I’m getting covered with my own smell.
After folding the body, the stomach is pressed so much that the stimulation is intense, and after masturbating while shaking the hips… I also felt regret that I masturbated vulgarly and that it was fortunate that we set aside time for each other to masturbate.

“Ha ha… Ha… Everyone, you’re back…”
“Yes, yes…”

Sometimes… There was a time when my younger brother arrived home just at the last minute and was almost in danger, but even though I could see him sweaty and messy, I couldn’t see him masturbating.
I was embarrassed at times like that, but… Her sister pretended not to know, so she passed by with her face blushing, and even so, her eyes kept turning to her sister’s thing that grew too big and protruded… I wanted to masturbate again.
But fortunately, nothing more was discovered…

And to some extent… About two weeks? From around the time…
I’ve come up with a problem.

“Huh… Whoop, whoop…”
“Hey, here… Are you feeling good?”
“Yes, yes… Oh, there, wait a minute… Follow… Oh, uh…”

It has already become a normal routine for my younger brother to give me a massage every day, after tutoring.
Her sister was also good at massage, but I also liked it, so I refused to say that her sister would do it every day, but eventually agreed.

But at some point… That, somehow I don’t know.
At first, the bodies that were a little apart got closer little by little…
Now, if I’m lying down, I’ll get on top of it… I was given a massage.
It’s just a posture for a massage, but it’s a normal posture like when you’re just giving a back massage…

On my ass all the time, that, big thing… I feel the heat because it’s hot.
Every time I press my back, my back feels good, but it feels like my butt is shaking.
Because that shape of my brother came to my mind.
The most difficult thing… I keep feeling naughty…
It was just too wet.

“Oh, no…”
“Ah, yes…”
“Uh, whoa, whoa… Ha ha, whoa… Go, thank you…”

The massage, which was given every day, continued a little bit at some point until the room became hot… The moment when the heat made me sweat slightly and I couldn’t stand it any longer, the moment I asked to stop was decided as the moment to stop.
The criterion for me to stop is… It was when I tried to get a massage and started lifting my butt slightly without even realizing it.
I tried to stop, but there was nothing I could do… It was like a movement that I made while masturbating, and I wanted to put it deep when I felt it, so it was just my body reacting, not thinking about it.

“Yes… Whoa… Ugh…”

Plus, the hand that massages the butt is really… That, every time I lightly stroked it, it felt like my hair was about to explode, so I was just giving her a massage, but I thought it shouldn’t be like this, but I kept feeling erotic.

The massage, which wasn’t like this at first, became like this, little by little, since I was caught masturbating. I thought it would get bigger by imagining it.
Rather, I put up with it and massage it… I was ashamed of myself for reacting this way to the extent of touching it a little.

There were good things about getting a massage like that every day.
I definitely felt that my brother and I became very close, and now we joke a little.
I play a little bit… We even talked a little bit dirty.
At first, my younger brother accidentally asked why I started using a dildo… I started by answering with the thought that since we are both adults, it is okay to talk about this much.

What my sister was curious about was that she thought that normal women don’t use tools, but after learning that I do, I was curious about it. I just bought it, and it hurt, but I tried a few more times without realizing it… I said I’ve gotten used to it.

“Women… Well, I like big men… ?”
“Yes… Big one, you might like it… I haven’t tried putting it in yet… Ah, I’m not sure if the other girls do too…”
“With instruments, and with sex… Do you think it will be different?”
“Yes… He, he, likes the heat, the feeling of scratching, he’s afraid of the mechanism feeling that way, so he slows down, but… A man can move freely in sex, because that’s different… ? And, I don’t know… Is it a feeling of being touched…”

Most of my brother’s questions were about women’s bodies.
Of course, I thought it was a time when I had a lot of questions about him, so I answered each one in detail, thinking that I wanted to teach him as well as I could.
It was embarrassing, but I still tried to tell it in as much detail as possible, and when I did, I felt my sister’s tremendous, flinching sensation from the side of my butt…
Then it became quiet and I just got a massage.

“Is the real thing and the machine… Very different?”
“I-I don’t know…I’m sure it’ll feel great…To the extent that it’s dangerous…”
“Do you have any reason… To be sure?”
“Th-because it’s so much prettier than a dildo…It’s so big… It’s hot, it’s…Very, well…It looks like it’ll scratch it…”
“And…?”
“That, older sister, there’s a point on the inside… That you can feel… Didn’t you? There too… It looks like it’ll be easy to press… Oh, that, that’s… That, the other… That’s… That’s why, it’s just a big… Cock, are you talking about a dildo? , Because it’s used… That, it’s as big as a dildo…”
“…I know, I have…As ​​big as a dildo…It is.”

And… Sometimes, I would ask my brother questions.

“…Ona Hall, is…Just masturbating…Is it different?”
“Because it shakes the waist… I guess, the feeling… I can feel the wrinkles…”
“Ah, as expected…The feeling of scratching…I like it, guys too.”
“That’s right… Haa… Onahole…That’s right, it’s different from the real thing…”
“Will it be very different…? Should I say… The wrinkles are deep and dense…Well, it takes a lot…It’s especially weak…That, I like scratching…”
“I see.”
“Um, are you using the shape of your butt well…?”
“…Yes.”
“How is it…?”
“The size… Is a little small, so it would be nice if it was a little bigger… But this much…”
“Ah…That silence followed is big…Well…Since it’s a masturbation device, it would be nice to have a big butt…Isn’t that a bit small…? Are you taller…?”
“Yes…”
“…It’s okay, so if you want to wear it, it’s okay to use your underwear again…?
“Haaaaa…”

While giving her a massage, we had a little but dirty talk, and when I couldn’t answer, I focused on the massage, and then I asked her to stop.
As we talked, the massage went a little slow, and it often ended late.

And when I stop and go back to my room… There was a creaking sound in my brother’s room, and sometimes the creaking of the bed.
And… The creaking noise in my room also became frequent.
