Chapter 16 – You Can’t Do This to Your Sister (6)
.
“Uh, forget about yesterday.”
“Hmm… Uh… Yes…”
“Yesterday, something went wrong and I made a mistake. Originally, I shouldn’t have done that with my older sister…”
“Right…”
“I-I shouldn’t have lost my mind so much about my younger brother. Sorry.”
The next day, I apologized right after waking up and having breakfast with my brother.
Something must have been wrong the day before, and when I came to my senses and thought about it, it was really embarrassing.
Her younger brother nodded, as if he thought so, and my face grew hot, but I held it in and told my younger brother.
“Well, now then… Are you good at concentrating on your studies?”
“Honestly, I don’t think it will be any more…”
“Why?!”
I shouted because I felt unfair, and my brother was calm as if he was saying something obvious.
“I saw it in the dark, so I couldn’t see that closely… My sister may have been able to see well because she was standing with her back to the window, but I couldn’t see very well.”
“Uh? Uh?”
“Even if I promise to only wear underwear during a massage, I feel ashamed and will ban it after I do it once…”
“Uh?! No, oh no!”
“Really?”
“No, uh… ? Uh… ? Oh, I won’t…”
“Then, starting today, if you score 95 or more on the mock exam, will you only wear underwear?”
“Uh? Uh?”
Before I knew it, I had promised what I said the day before.
My younger sister went to the academy with a smile on her face, and even after sending her younger sister away, I kept feeling strange and lost myself in thought.
What? Uh? Why did this happen? I kept wondering how this happened, but… No matter how much I thought about it, I couldn’t find an answer.
What the hell did this happen… ? I was so shy that I rarely masturbated at lunch after that.
Fortunately, I didn’t get more than 95 points in the mock test from the first day. But… It wasn’t long before the scores started to rise.
Feeling uneasy, I even said that I would ban massage if the test score was not high, and my younger brother was dissatisfied at first, but… Instead, he told me to keep the promise that if he scored 95 or higher, he would give me a massage in his underwear, so I nodded.
The score went up little by little after that, and after that, it became rather strange to drop below 90 points.
When I saw the score, I became very complicated, and I felt good because the score went up, but I became anxious about something.
And finally, after more than a week, I passed 95 points.
“Uh? Uh? Wait a minute, let me try again…”
I couldn’t believe it, so I re-scored and re-scored, but the score was 97.
At this level, it was natural to pass, and it was good enough to prepare for the next level of certification.
I was perplexed yet congratulated, delighted but perplexed.
My younger brother said that because he has a clear motivation, he studies much better… I just said it quietly without being happy or not.
And I, in the end… After a week, I received a massage from my younger brother, and really, just in case, I was wearing… A little naughty, I came to show my sister wearing pretty underwear.
“Again, you can’t do anything weird again… ? Are you just giving me a massage?”
“… Seriously, your silence followed is so pretty…”
“I-I told you not to say that…”
And strangely, ever since that happened… Outside of tutoring time, I avoided my younger brother as if I was avoiding him and my conversations were reduced. After a long time, with my younger brother… I had a dirty talk.
In a room with only a mood light on, my younger brother sat on her buttocks with only underwear on. .
“Sister, but… Why do you keep raising your butt when I say dirty things?”
“That, that… Because it’s a habit… I don’t know… Ugh, ah…”
I am… If my younger brother said a little dirty talk or touched only a slightly sensitive place, I would raise my butt without realizing it…
I didn’t want to do this either, but my butt kept lifting on its own, and every time it happened, my younger brother’s thing was put more clearly on the hip bone, and it felt very hot.
Because of that, if your sister’s things get bigger… My sister apologized by stroking her butt lightly as if she was very sorry.
“My sister’s body is too erotic… I’m sorry that I couldn’t stand it anymore.”
“Ah, sorry… It’s okay, that’s because he’s a man… Hehe, I’m sorry…”
And… As such actions continued to repeat, I became more and more in the posture of raising my hips while only lowering my upper body, and my younger brother’s things gradually came to me… The number of touches has increased slightly.
My younger brother massages my back and back every time… I would let out a long sigh in embarrassment when something that had grown so large got stuck between my hips.
“… I can’t do this…”
“Huh, huh… It’s okay, it’s okay… Since it’s a boy, it’s just a massage, Igoo…”
My brother and I were completely overheated and soaked in sweat.
My younger sister said that her clothes were getting too wet and she was only wearing underwear, and as time went by, her hips lifted… I was hugging the pillow and burying my face in it, allowing my sister to hold onto my waist as she pleases.
“Haha… This, now, sorry…”
“Whoa… Whoa…”
“Ah, no, no…Really, no more…Haaaaa…
“Whoop, whoop… Yes… Yes…”
The timing to stop the massage is also completely different… My younger brother grabbed my waist as I was lifting it up… When it turned into a posture that seemed like it was no longer a massage, I came up with the word to stop.
The younger brother then came to her senses and stopped.
I went back to my room, blushing and saying good night… I couldn’t stand it and put a towel in my mouth and masturbated…
My brother also went to the bathroom after a while and heard the sound of turning on the water…
At some point, the score came out unconditionally over 95 points, and that happened over and over again.
My younger brother’s gaze at me has gradually changed, and the way I look at him has also changed little by little.
“Sister, wait… Tea is coming.”
“Heh…That, there…Uh, on the hip…Hand…”
“Ah, I’m sorry. I accidentally…”
“City, even if you accidentally open it, you can’t squeeze your butt like that outside…”
My brother has more touches in everyday life than before, as the number of strange touches on my body has increased, and I have… The thought of massage made me feel more ashamed.
“You… Uh? What? Uh… ? Are you in love?”
“Uh?”
Around that time, my friend got a job, so we started drinking together… Weird talk.
“No, why did my self suddenly become prettier? She used to be pretty.”
“What, what are you saying… Do not say that.”
“Look at this! Look at this! You weren’t a kid with such a charming voice!”
“Uh? Uh?”
“Are you so cute?! What happened in that moment?!”
“Wow, what nonsense. I am just the way I am.”
“… Do you have a boyfriend?”
“Under? Can you stop talking really weird?”
Really, I didn’t change at all, but when I suddenly said that, my friend started talking nonsense.
I was dumbfounded, but my friend kept saying that I had really changed.
“No, the skin… No, originally, you didn’t have acne because you exercised a lot, but… My skin got better Because of your personality, you won’t go to any clinics…”
“Why does that lead to having a lover?”
“You become pretty when you love.”
“Say something that makes sense. It is unscientific.”
“No, love is not necessarily emotional. When you have sex, when you receive sexual stimulation from the opposite sex, female hormones just come out and many good things come out of your body, and your skin really improves. Is this scientific? Shall I show you the thesis?”
“All right, all right.”
Since then, I’ve been worried about something and the number of times I look in the mirror has increased.
Has anything really changed? I wanted to, but I didn’t feel it at all.
And every night… It has become nothing new for my younger brother to take a test and get over 95 points.
“Ah, ah, ha ha, ha ha, ha ha, ha ha.”
“Hoo-wook… Whoop…”
Now at all… Thinking about what happened after the exam, I taught with only a cardigan over my underwear.
When the exam was over, I took off my cardigan and put on my underwear… My younger brother was wearing only shorts and a shirt… I took it off slowly, and it made it easier to press it well… I even put a pillow under my stomach.
However, I thought that it was not going to be a massage… I pressed it hard enough that the underwear only stretched there, but… I didn’t put it in or cross the line.
Because the back is pressed well… And at first they really do a little massage… I thought it would be okay to do this.
I buried my face in the bed trying hard not to say anything dirty without saying anything, and for some reason the stimulation seemed to be getting stronger as the days went by… There are more moments when I clenched the bed sheet tightly with my fist.
“Oh, no…”
“Whoa… Whoa…”
And, I lost my mind and stayed still… By the time I get so wet that even my underwear makes a sloppy sound, I’m so embarrassed… I begged you to stop.
After that, the trash can that I no longer take out at lunch… My brother gave it to me.
“Uh, this… Today, I didn’t clean it up, more…”
“Yes, yes…”
Then I would blush and take the trash can… I went back to my room…
Inside, the younger brother now returns rather early, around lunchtime… Masturbating while I said I was going to buy food for dinner… Semen, whatever… I have a condom.
“Huh… Whoa… Ha, ha, ha, ha, uh, uh…”
Then I’ll take it and go… Gently stick out your tongue, lick it, sniff it, masturbate with a towel in your mouth…
The next day, again, in the evening, tutoring, massage… And masturbate…
Even though I know that everyone found out that I was masturbating, I still can’t stop…
My younger sister, as a matter of course, is now handing her semen to me… Crab…
“This, this, we’re weird these days…”
“Uh? What?”
“That is… Anyway, he’s a boy. That… Even if there is sexual stimulation to each other, and you think that you have to solve it… Well, this is kind of weird.”
“Uh? Come now… ?”
“Hey, come now. That this is wrong It’s my sister, it’s my sister…”
It became strange at some point, and I remembered my friend’s words, and I couldn’t stand it.
I think I just wanted my younger brother to not be stressed while studying, but as my friend said, at some point… I realized that we were very sexually stimulated and given each other.
This is, no matter how close to 15 years we haven’t met, so even if we don’t feel like siblings… I thought it was strange.
We lived together for several months, but we didn’t see each other more and more as siblings, but rather, as time went on, it got worse, and seeing each other with such sexual eyes… I thought it was bad.
I thought that special measures were needed… I thought it was really dangerous at this rate, so I told my younger brother.
“From now on, masturbation is prohibited.”
“Uh?!”
“It’s not good to solve everything as soon as the desires pile up! Ah, in the first place… No matter how much I said… It’s weird for a younger brother to give his sister a trash can of semen to masturbate to…”
“Uh? No, really, come now… ?”
“It’s not like it’s come now, but even now, you know what’s wrong. I mean, this is weird…”
“Uh… Hmm… So, massage is also prohibited?”
“… Do you want a massage?”
“Yes…”
“Well, then… Can masturbation be banned?”
“… I will try.”
I felt very sorry for my younger brother who studied hard for not letting me do everything from the beginning, so I decided to stop masturbating for now.
After that, there were no more toilet paper or condoms with semen in my brother’s room.
Instead… The massage time was very long and…
Me too, when I saw that there was no toilet paper in my sister’s room… I thought you were putting up with it diligently, so even if I got wet or embarrassed, I put up with it.
Right before going to bed, my brother massaged me and then went to sleep.
“Ha, ha, ha, uh… Wait, too, ah, too touching, ah…”
“Whoa, whoa, whoa…”
“Ah, I can’t… No. No massage It’s not a massage, right? Haha, no kid, I mean I’m sensitive. It’s strange these days…”
“Haha…”
“No, no, no, it’s weird, it’s weird… Ugh, it’s weird… Whoop, whoop, whouh… Aaaaa…”
The problem is… Because I put up with masturbation…
My body has become much more sensitive…
It was much more wet…
