When you grow up, you must protect your older sister (my older sister).

【You must protect your sister when you grow up】(My Sister)
(I)
I have a sister, and I love her very much because she is always very kind to me, takes good care of me, and is willing
to take me everywhere to play.
My sister is about two years older than me. When we were little, we always took baths together without any hesitation. Our parents
didn't worry because we were young, but because of this, many things happened between us later.
When I was little, I hadn't yet developed any sexual knowledge. My sister and I still slept together. Since I had always taken baths
with , I wasn't very interested in her body, and my sister didn't care much at the time either. But I always
remember that when my sister rubbed my penis with her hand, it felt quite comfortable, so I also liked it when my sister washed
it. However, whenever I wanted to wash my sister's body, she would always laugh and say that I wasn't clean enough, and that I should soak
in the water first, and then she would wash herself.
But strangely enough, we only had these kinds of things happen when we took baths. We slept in the same room at night,
but nothing happened.
Anyway, we just took baths together like that until I was in fourth grade of elementary school, and my sister was in sixth grade of elementary school
one day. Back then, the manga "City Hunter" was all the rage. My sister and I both loved reading
it and laughed out loud. However, I didn't understand any of the dirty jokes, especially
why the protagonist Ryo's penis would grow longer and bigger. Since I couldn't get an erection at the time, I
could only look at it without understanding.
Later, one night, I couldn't fall asleep and thought about
the pleasure of my sister holding and rubbing my penis while I was showering. So, I started holding it myself under the covers and began to move it randomly. Suddenly, I found that this feeling was even more
pleasurable, and I started to feel something was wrong with my penis. That's when I realized that if you keep touching it until you get an erection...
After I took off my clothes in the shower, I laughed and called out to my sister to get her attention because I thought I could be
like the protagonist, and my sister would be very happy. After my sister took off all her clothes, she asked me what I wanted to do.
I told her to sit on the small wooden chair first, then stood in front of her and said, "Sister, look, I can be
just like the guy in the manga 'City Hunter'..."
Then I started rubbing my penis with my hand, feeling a slight pleasure, and my penis began to
get engorged and grow larger.
My sister watched with wide eyes, becoming more and more surprised as my penis grew bigger and erect.
I said to my sister, "Look, my little penis has gotten so big, just like in 'City Hunter'..."
My sister just kept looking at me without replying, occasionally staring at my face, and sometimes looking down at my
erect penis. After about a minute, I naively asked her, "Sister, do you want to touch it?"
My sister was startled by my question and looked up at me before saying, "You can't do that."
At that time, I didn't understand that such behavior was forbidden; I just thought my sister's reaction was strange and a little disappointed because she didn't express the joy
I had expected from me, like Ah Liao ... Unable to hide my disappointment, I said to my sister again, "Touch it, it's very hard!" My sister looked up at me, then at my penis. I told her again that it was okay to touch it. After about half a minute of silence, my sister finally reached out and gently grasped it. My sister didn't grasp it very firmly, just carefully and gently touching it, occasionally pressing down to check . I was just standing there letting my sister touch me, enjoying the feeling of her holding my penis. Actually, my sister was probably more curious than I was; I could tell from her eyes and actions. But perhaps because she already knew a little about these things, she felt guilty and didn't dare to do anything reckless that night. That night, that was all. My sister touched me once and then let go. I wanted her to praise me, but she didn't say anything, so I didn't dare to speak either. I thought I had done something wrong and quietly took a shower. My penis slowly went back to its original position. I remember those few nights we didn't talk much while showering. Because I was afraid of upsetting my sister, I didn't dare to show off to her anymore, just quietly showered. After a while, I remember one night when I was showering with my sister, I was standing, and my sister was squatting in front of me, scrubbing my feet. Then, she silently reached out and touched my penis, and started scrubbing it. My sister used to do this for me before, so I didn't find it too strange. But this night was different. My sister seemed very nervous that night, not saying much, just staring at my penis and rubbing it, unlike before when she would just wash it. I found it strange, and because of her rubbing, I felt pleasure, and my penis started to grow and become erect , but she kept rubbing until it was at its maximum. I kept looking down at my sister, and when she noticed me staring, she looked up at me, her expression a little nervous. My sister said nervously, "Let me help you wash it a little cleaner..." I just nodded, and then she pretended to be washing me, continuing to rub my penis and observe it . But at that time, I didn't realize that my sister had become interested in my penis, so I foolishly let her play with it until she seemed finally satisfied and then started coaxing me not to tell anyone. At the time, I really didn't understand, so I asked her why. My sister nervously gave some nonsensical explanations, but I still didn't understand. In the end, I could only promise her not to tell anyone, and only then did my sister finally relax... Every night when my sister showered, she would help me wash my penis, and I was happy to let her massage it until it was erect. It was truly a case of one willing to give and the other willing to receive. At first, she was a little embarrassed, but after a while, we were chatting and laughing, and everything seemed so natural. My sister would even ask me how it felt, but I didn't know that feeling was pleasure, so I just told her it was quite comfortable. I would even proactively put my penis in front of my sister at the very beginning of the shower, letting her hold it until it was erect before I started washing. Then, one afternoon when I was home alone after half a day of classes, because my sister had gone out with her classmates, I was bored and went to look through my dad's videotapes to see if there were any cartoons, but I unexpectedly found a roll of porn. I looked at the contents with surprise, and this pornographic film awakened my sexual awareness... Although I didn't know the meaning of sex at that time, I already knew the difference between , that penetration was possible, and that it looked very pleasurable. So that night while showering, I started to study it.

From that day on, I kept a close eye on my sister's vulva, wanting to see it clearly, but I was
afraid of upsetting her, so I didn't dare to do anything.
However, I soon noticed that she always washed her hair at the sink, so she had to stand in
front of it and bend over, causing her buttocks to stick out. Plus, she washed for over ten minutes each time, knowing this was my chance.
So , the night after I discovered this opportunity, after she finished washing me, she rushed into the tub. I waited for her to start
washing her hair, then secretly stood up from the tub and carefully knelt behind her.
At first, I only saw her buttocks, nothing else. Then, it seemed she
wasn't bending low enough while washing her hair, so she spread her legs wider and moved her body downwards, and I could vaguely see her vulva,
almost like in porn.
I secretly held my penis, watching her vulva, finding it very novel. A few minutes later, she
suddenly turned off the tap, having finished washing her hair. I quickly returned to the tub, trying to pretend nothing had
happened. I was a little too slow. I'd barely stepped into the bathtub when my sister, drying her hair with a towel,
turned around and asked why I was standing up.
She hadn't noticed I'd just peeked at her private parts, but I felt a little guilty.
I stammered that I was done washing and quickly got out of the tub, dressed, and left.
That night, all I could think about was my sister's genitals. Before bed, lying in bed, I couldn't help but grab
my penis and make it hard. I kept thinking how strange I was, why was I so obsessed with my sister's genitals?
For a while, I'd been sneaking peeks at her genitals while she washed her hair at night, and luckily, she never
found out. So I gradually became addicted.
Then one afternoon during a half-day of school, while my sister wasn't home, I watched a pornographic
videotape . It was a different tape, and it excited me just as much.
Of course, I was watching while holding my penis, but when the porn shifted from the room to the bathroom, and
the male lead and actress were playing in the water, and finally the male lead pressed the actress's upper body down
and penetrated her anus from behind, it suddenly gave me a shock… and it changed my relationship with my sister.
Before, I had only spied on my sister washing her hair, but this video made me, in my naivety at the time, realize that such a situation was
possible. If I could penetrate her from behind like in the porn while she was bending over to wash her hair…
honestly, who would think that a fourth-grade elementary school student would have such a plan? Especially my sister, although
she would curiously play with my penis when we showered, our sexual relationship was nothing more than that, and
she certainly wouldn't be too wary.
In short, I was very nervous after watching the porn that day, and when my sister came home, I was even more restless
. Because I genuinely wanted to try it myself, to see what would happen if I inserted my erect penis into
my sister 's anus, but I was afraid she would be angry. So I kept telling myself, "
Let's see how it goes first, and the actors in the movies all seem so comfortable, my sister probably won't be angry
..."
But although my sister didn't understand what I was worried about, and since I'm not good at hiding my feelings
, she asked me what was bothering me, but I could only answer that nothing was wrong.
That day, during the final shower, I still didn't dare to do anything, because I was afraid my sister would be angry, and I was also afraid my parents at home
would find out. So I only dared to peek at her when she was bending over to wash her hair, and after the shower, when it was time to go to sleep, I
hid under the covers, grabbed my penis, and started to regret it, thinking that I should have tried it...
In short, that period was really tough, I was hesitating every day about whether or not I should insert it into my sister's anus?
Just as I was worrying about these factors, the opportunity unexpectedly came. Suddenly, my parents told my
sister that they wouldn't be home that night because they had to rush to visit relatives in the south and wouldn't be back until the next evening.
They asked my sister to take good care of me...
Finally, it was time to take a bath again. I was half nervous and half excited because I knew my parents wouldn't
be home . It felt like they had finally made a decision for me. If I penetrated my sister's ass and she got really angry,
I could just apologize to her. There was no one else at home anyway.
My sister and I went into the bathroom again. We took off our clothes, and my sister started rubbing my penis until it was hard again,
watching its changes. I knew my sister still thought I was naive and didn't understand these things at all. She was just
using the excuse of taking a bath to study my penis. But by this time, I already knew that a man's penis could be inserted into a woman's ass,
and I had decided to try it.
My sister finally got used to playing with my penis. She helped me rinse off the soap suds and then told me to
soak in the bathtub. After she washed her hair and body, she would come into the bathtub and play in the water with me.
I started to feel heavy breathing, mostly from nervousness, so I stayed in the warm water, constantly watching my sister
's movements.
She was also leaning over the sink, head down, rinsing her hair with the showerhead and
shampoo, quickly covering her head in fragrant bubbles.
Seeing that her head was covered in bubbles, I knew she couldn't lift her head or move, so I nervously climbed out of the water
, silently walked behind her, and immediately moved my erect penis towards her buttocks.
Since we were about the same height, and I already knew the location of her vagina, I quickly
positioned my penis where it would be.
Suddenly, my sister made a soft "hmm?" sound, clearly reacting to my penis touching her genitals. She stopped
washing hair, slightly raised her body, and turned to look at me,
meeting my gaze.
Nervously, I quickly pushed my penis towards her buttocks, placing my hands on her waist, trying to insert it into
her vagina, but it felt like I was hitting the bone, not penetrating.
"Ah! Brother, what are you doing?!"
My sister screamed in alarm. She must have realized I was trying to penetrate her anus, and since I hadn't managed to get it in
, I quickly said to her, "Sis... I just wanted to try..."
My sister just stared at me with wide, astonished eyes, as if struck by lightning. She couldn't believe that I, a fourth-grader,
would suddenly do something like this to her private parts.
I nervously moved my penis to adjust its position, and my sister, who had just come to her senses, started screaming again, "You
can't do this! Get away from me!"
I thrust again, and suddenly felt a sharp pain in my penis, like a layer of skin being ripped off.
My sister screamed, "Ah!!"
The glans really hurt because the foreskin suddenly retracted the moment I inserted it;
otherwise, it would have been covering the glans. I hadn't realized it then, so after feeling the pain, I
was too scared to go in any further.
My sister, after screaming the moment I inserted it,
stared at with a look of terror I'll never forget.
I looked down and only saw about the tip of my penis inside. Thinking that it hurt this much, I wondered how much it would hurt if it went
all the way in. So, I didn't feel any pleasure, only pain. Seeing my sister's
scream and the expression on her face, I became afraid too.
"Sister… does it hurt too?" I asked her fearfully.
Tears streamed down her face, and she said in surprise and horror, "How could you do this..."
It was the first time I'd seen my sister cry because of me, so I quickly pulled my penis
out, feeling a sharp pain. My sister groaned.
It was the first time I'd seen my own penis; it was completely red. But my sister's tears
terrified . Knowing I'd pulled away from her, she started sobbing on the sink, wailing.
That night, seeing her cry like that, I knew I'd done something terribly wrong, so I knelt beside her,
apologizing profusely. But after crying for a while, she washed her hair, sat on the floor, and without regard for
me, spread her legs to examine her genitals, even taking out a small mirror to look at herself.
I couldn't help but look too, seeing her completely open vulva, the opening slightly
ajar, probably from my penetration, and even seeing some blood trickling out.
My sister cried and yelled at me, "How could you do this! How am I supposed to get married?!"
Of course, I didn't understand at all, and I didn't even know that inserting my penis into my sister's butt was sexual intercourse and could result in a baby
. So I could only kneel down in fear and apologize to my sister...
(II)
At that time, my sister was in fifth grade and I was in third grade. My sister was a more mature and composed
girl than her peers, and she took good care of me. So she was particularly shocked by what I had done to her.
That night, my sister cried and kept yelling at me, asking if I even knew what I had done to her.
When we went to bed that night, my sister was still lying in her bed, crying quietly. So I hardly
slept , and I was late for school the next day. My sister didn't call me and I went to school by myself.
I still didn't understand why simply inserting my penis into my sister's butt would make her like this. I felt extremely
regretful and kept apologizing. Even after I got to school, I kept running to my sister's classroom to apologize to her, but my sister
didn't say anything and even sent me back.
I thought my sister would tell my parents what I had done when they got home that evening; but she didn't.
She was just sullen all day, at least she wasn't crying anymore.
After my parents got home, they went to take a shower first, while my sister and I stayed in our room doing our schoolwork without
saying a word . When they came out of the shower, my mother told my sister and me to go shower together, saying the water was still hot. This made me
start to worry again and secretly watch my sister.
But my sister just calmly agreed and went to the closet to get her change of clothes,
walking towards the bathroom without saying a word.
Usually, my sister would ask me to go shower with her, but she didn't today, so I thought she must
dislike me for doing that, so I could only obediently continue doing my homework.
Unexpectedly, a few minutes later, I felt a tap on my shoulder. I turned around and saw my sister saying expressionlessly
, "Didn't Mom and Dad tell us to go take a shower? What are you still doing? They'll scold you if the water gets cold."
At that moment, I really didn't know what to say to my sister, so I could only apologize to her again and quickly go to
the closet to get my clothes. Because my older sister always helped me with my clothes, I couldn't find them anywhere
.
She came over, silently started searching for them, and placed them in my hands before
leading me to the bathroom…
Once inside, I felt like my sister had forgiven me, and I even naively thought that things would return to normal in
a few days , which made me feel much more relaxed. So I started taking off my clothes, but my sister
spoke first, saying, "Do you know what you did to me last night?"
I stopped undressing and quickly shook my head.
"If you don't know, then why did you do that to me?"
When my sister asked this, and saw her serious expression, I became scared and didn't know
what to say. But unexpectedly, my sister seemed to know what I was thinking and said, "It's okay to tell me,
I won't scold you."
So I could only carefully answer her, "Because… I watched the videotape in Dad's room, and they seemed to be having fun doing that in
the videotape , so I thought that if I did that, you would like it too…"
After saying this, I apologized to my sister, and she just looked slightly
surprised .
I apologized to my sister again, saying I really didn't know she would do this. Finally, without saying anything, she
started helping me undress. Because she sometimes helped me undress while showering, I obediently
cooperated.
I moved my arms and legs with her movements, raising my legs so she could take off my pants.
Just as I was finally down to my underwear, my sister looked at me and said, "I
ca . You've taken my virginity, do you know that?"
I was startled and looked at her, but she said it so seriously, leaving me completely
speechless .
At that time, I had watched a lot of prime-time dramas with my sister. Even if I didn't know what sex was, I
knew that virginity was very important to a girl, and even thought that girls without virginity were bad girls,
so I started to worry. Plus, my sister was still quite naive at the time, or perhaps she had watched too many dramas like me,
believing that without virginity, she wouldn't be able to get married…
I apologized to my sister again, saying I didn't mean to hurt her. My sister seemed to have come to terms with
it just told me to take off my underwear and start showering.
I started washing my body, and my sister took off her clothes as well. She took the soap from my hand and started washing
me , but kept avoiding washing my penis.
Suddenly, my sister asked me, "Do you like me?"
I kept nodding.
"Since you caused me to lose my virginity yesterday, are you willing to take care of me from now on?"
My sister naively believed she would never get married, so she used the excuse of me having to take responsibility to replace the
idea .
But at the time, I was young and didn't understand the meaning behind my sister's words. Plus, my sense of guilt about incest was very weak
. I only knew that siblings couldn't marry, but I didn't know that marriage meant taking care of my sister,
or even more. So when my sister asked me if I was willing to take responsibility, I agreed. After all
, I thought it wasn't marriage, just taking care of my sister shouldn't be a problem, right?
After hearing my agreement, my sister finally smiled happily and hugged me, saying, "When you grow up
, you have to protect me!"
I was very happy to be hugged because I really felt that my sister had forgiven me. At that time, I just wanted to
grow up quickly so that if anyone said my sister had no virginity, I could protect her.
When my sister let go of me, she warned me, "You can't tell Mom and Dad what happened,
or they'll beat us."
Hearing that I'd be beaten, I nodded quickly, because I was still terrified of Mom's stick and Dad's
slaps , and I never intended to tell anyone anyway…
Then, nothing happened during the bath that night. We resumed our happy bathing atmosphere.
After my sister helped me clean up, she made me wash my penis while she washed herself. Then we started splashing
each other water until Mom called us from the doorway.
That night, I went to bed and we were as open and talkative as ever. We lived a
peaceful life for a while longer. Although I was still curious about why I had penetrated my sister's butt,
I didn't dare ask her, so I kept it buried in my heart.
But before, my sister would masturbate while bathing me every night, so I was satisfied. But
after that day, my sister stopped washing my penis, and I didn't dare touch it myself anymore.
I could only obediently endure it until finally, when I couldn't take it anymore, I asked my sister while showering, wanting to touch it but worried about doing something wrong, "Sister...
can I touch my penis?"
My sister was stunned by my question, just looked at me, and then smiled and said yes.
So I quickly stood in front of my sister and started rubbing it with my hand, feeling the satisfaction of pleasure. As my erection grew
, I was surprised to find that the outer layer of skin could actually peel back, slowly revealing a red glans,
just like the day I inserted it into my sister's anus and then pulled it out.
My sister kept watching, and I curiously touched my glans, but I felt an even stronger pleasure, one I had never experienced before
, a tingling sensation like being electrocuted, and I couldn't help but let out a soft "ah."
My sister asked me what was wrong with her, and I replied that it felt strange, but also very comfortable, so I
started touching my glans again to study it. My sister only looked and didn't touch it, but at least I got
the pleasure I had longed for, so I was satisfied.
That night, we didn't turn off the lights before going to sleep; actually, it was because I was making so much noise that my sister couldn't sleep. We lay in our respective
beds , and I continued to hold my penis under the covers, rubbing the glans to feel pleasure. I also whispered to my sister that this
intense feeling was strange, and said other things.
When I asked my sister why she felt this way, she replied that she didn't know either. After all, at that time, my sister only
knew about sex and virginity, and didn't know what pleasure was.
The next night, after taking a shower, I immediately started masturbating in front of my sister,
playing with the glans to feel pleasure.
My sister, as usual, took off her own clothes and occasionally watched my masturbation while she
started washing her own body.
I continued to play excitedly until my sister finished washing herself and said to me, "Okay,
take a shower first,"
and picked up the soap to help me wash.
I stood obediently while my sister washed my body. As she washed, she nervously glanced up at me
and asked, "Can I wash this part for you, sister?"
Hearing that my sister was willing to touch my penis again, I quickly replied, "Sure, don't
you wash this part for me?"
So my sister finally reached out and grasped my penis, starting to scrub it. However, she only brushed the
penis, never touching the glans.
"...Sister, won't you touch that red spot?"
My question made my sister look up at me for a moment before finally touching it with her finger, giving me a
strange sensation.
So, my sister scrubbed my penis, then my testicles, then the glans; it felt
really good .
"Sister..."
"What is it?"
"Can I ask you something?"
"What?"
"That day... when I inserted it into your butt... did it hurt a lot?"
My sister was still washing my penis with her head down, a little shy and smiling, and said, "It only hurt a little bit..."
"Sister screamed so loudly that time, I thought you were in pain too... but I felt really pain then..."
So we returned to silence, and my sister continued to "wash" my penis, and she had been
washing it for more than ten minutes...
"...Do you want to do it like that night again?"
Hearing my sister ask me this suddenly really startled me, and I quickly answered, "No! It
will hurt a lot!"
My sister just smiled and didn't say anything, and then after a few minutes she asked me again, "Are you really willing
to take care of your sister from now on?"
I was a little surprised that my sister suddenly asked me this, so I just nodded in response, and then
my sister finally looked up at me...
(III)
My sister was very strange for those few days, as if she had something to say to me, but in the end she just called me
and said it was nothing.
When we're sleeping at night, we're lying in our own beds. I'm about to go to sleep, but sometimes my sister will
suddenly call out to me and then fall silent. I ask her several times what's wrong before she finally says nothing.
The last time, I got a little annoyed and was about to ignore her and go to sleep, but my sister called
me again.
"What is it?!" I asked her impatiently.
She finally managed to speak: "Did you secretly watch the videotapes in Mom and Dad's room?"
I simply nodded, and then she said, "
You have half a day of school tomorrow afternoon. When Mom and Dad aren't home, can you show them to me?"
Hearing this, I thought to myself, if it's just something like this, why is she being so
hesitant ? I simply agreed, and she just vaguely said, "Because I haven't watched them..." and didn't
say anything more.
The next afternoon after school, after lunch, I took my sister into Mom and Dad's room and took out two or three videotapes from the
cabinet , asking her which one she wanted to watch.
The videotapes all featured women posing in various lewd positions, occasionally showing scenes of intercourse.
My sister stared at them for about ten seconds, then suddenly asked, "Have you seen all of these?"
"No, these seem to be ones Dad recently rented."
"Then put this one..."
My sister handed me one of the tapes. I curiously looked at the box, wondering why she chose this
one, but I couldn't see anything special about it. Maybe she liked the actress.
The tape was inserted into the machine, and I turned on the small TV and sat on my parents' bed with my sister. My sister
stared intently at the content, while I pulled down my pants and masturbated.
Neither of us spoke. My sister's attention was mainly focused on the TV, while mine was half on
the TV and half on my penis.
About half an hour later, the scene finally showed the two having intercourse. The man inserted his penis into the woman's anus, and they both
looked like they were enjoying it, but I was just thinking, "Liar, it clearly
hurts . It's better to just touch it myself."
My sister just kept watching without saying a word.
Finally, the scene ended, and the man sprayed white fluid into the woman's mouth. That was it.
I asked my sister, "Should I turn off the TV?"
She nodded, so I took the movie out, turned off the TV, and put my pants back
on ...
I thought that once the movie was over, my sister wouldn't be like before, but she seemed even more
preoccupied .
That night, as I was about to turn off the lights and go to sleep, my sister suddenly called me again and whispered, "Are you asleep?"
"Not yet..."
Then she didn't say anything. I waited a few more minutes, and just as I was about to give up on sleeping, my sister said, "After you
hear Mom and Dad go back to their room to sleep, will you come to my bed and chat with me?"
Although I found it strange that I had to wait until my parents went back to their room, I still agreed.
But while waiting for the sound of my parents going back to their room, I actually fell asleep.
The next morning, my sister woke me up to go to school. She asked me why I fell asleep last night, and I remembered this and
said I was really too tired and suddenly fell asleep. My sister didn't say anything. So I mentioned again that I would definitely come and
chat with her that night, and she nodded and said "Mmm. "
While showering that night, my sister secretly scrubbed my penis, studying it for a while without
saying . After she finally satisfied her curiosity, I soaked in the water waiting for her to play.
When we turned off the lights and went to sleep, I tried hard to stay awake. Finally, I heard my parents' bedroom
door close, so I grabbed my pillow and quietly went to my sister's bedside. She pulled up the covers and let me lie
down.
We rarely slept together, so we lay on our sides, looking at each other, and couldn't help but smile.
"What does my sister want to talk to me about?"
I asked. She returned to her smiling silence, and after half a minute, she said shyly, "
Can you take your pants off?"
I didn't know what she wanted to do, so I asked her, but she just said, "Just take
them ."
So, I reluctantly started taking off my pants under the covers.
Just as I took them off, my sister reached out from under the covers and suddenly pulled down my underwear,
looking at me with a slightly nervous and shy smile.
I suddenly realized that my sister might want to play with my penis, just like I used to play with
it , so I asked her if she wanted to touch it. If this is what my sister meant by chatting, then I'd really like
chatting with her every night.
"Hmm..." my sister finally answered with a smile, and I felt comfortable letting her touch me. She quickly took it
in her warm hand and started rubbing it until it grew bigger.
"...Will you always hate it when your sister does this to you?"
my sister asked worriedly. I told her no, I like it too.
Then we just lay on our sides, looking at each other and laughing, feeling the mystery of sex, secretly playing children's sex
games.
Actually, my sister has always been very curious about sex, after all, she's only in fifth grade. She just
understands that you can't do this kind of thing casually, so she's always been very reserved.
My sister kept touching and playing with my penis, while I kept my hand on her arm. We just happily
said things like, "My penis is so hot," or "It's so hard..." and so on. I even joked that when I grow up, I want my penis to be
as big as Arakawa's in City Hunter.
After playing happily for a while, my sister asked, "Don't you think it's bad of me to touch your
penis ?"
I quickly shook my head. My sister had always been very caring and kind to me, and she was willing to touch my
penis . She finally smiled with some relief and said, "You'll take care of and protect your sister when you grow up, right?"
"Yes..."
Then my sister fell silent again, continuing to play with my penis under the blanket.
After a while, my sister called my name, "You..."
"What is it?"
My sister suddenly became a little flustered, saying, "I'm really curious... and it's
okay now... so..."
I still didn't understand what she meant, so I just kept looking at her. Finally, my sister made up her mind to speak
: "...Do you want to try again?"
My sister asked me with a slightly nervous and shy smile, but I suddenly didn't understand, so I asked her
what she meant.
“…It’s just…try inserting it into your sister’s ass again…”
“But didn’t you say that I would take your virginity?”
I asked my sister worriedly. But she just said, “
It’s okay .”
Even though she said that, she still asked to do it with me again. I was worried and scared and asked, “
Will hurt again?”
My sister said, “Didn’t Dad tell you that boys shouldn’t be afraid of pain? Otherwise, how will you protect
me in the future?”
So, that’s how my real sexual relationship with my sister began that night…
Although I was afraid of the pain, I still didn’t dare to resist my sister because she had always been very good to me. So after reluctantly
agreeing to my sister’s request, my heart was still filled with fear and unease.
My sister worriedly warned me that if it still hurt, I had to endure it and not make a sound so that
Mom and Dad would find out, or I would be beaten.
“When you grow up, you have to take care of and protect your sister…”
Then I felt my sister start to take off her pajama pants and underwear under the covers. She smiled and looked at me, then slowly leaned towards my
body and gently hugged me. We lay on our sides on the bed like that.
My sister and I were very close, almost touching. Then I suddenly felt
her hand grasp my penis, and her feet started moving around.
My sister smiled at me, a little nervous and shy. After a few seconds of her foot movements, I
felt closer, our stomachs touching, and my penis was warmly held between her thighs—
it felt quite comfortable.
My sister told me not to move and that she would use her thighs to hold my penis, saying she wanted to do it like that first.
I couldn't help but smile at her, and after a moment of gazing at each other, she nervously said she was ready and
I could do whatever I wanted.
Although she was ready, I wasn't. I was terrified of pain, and besides, I didn't know what
to do…
“Sis… I don’t know how to do this…”
Then my sister widened her eyes: “You don’t know how?”
“I can’t see like this…” Then she laughed again and asked me what I wanted to do.
“Can you lift the blanket? I can’t see like this…”
My sister then released me, spread her legs, no longer holding my penis, and lifted the blanket.
I sat up in bed. In the dim light of the nightlight, I could clearly see my erect penis and my sister's
naked lower body.
My sister also sat up, her legs together, and she slightly covered her lower body with her hands.
I just stared at my sister's genitals until she smiled and asked me, "Is it okay?" Only then did I think to
continue.
My sister lay back down, her legs together and bent on the bed, watching me nervously. She slowly spread her legs
apart, gradually exposing her vulva to me, until it was fully open, her vaginal opening slightly parted.
I was just staring, completely captivated, until my sister couldn't help but laugh and ask me, "
Are ?"
"Yes..." I replied nervously.
"You should be able to do it like in those videos..."
So I slowly climbed on top of my sister, holding my penis in one hand, and slowly pressed it against her
vulva, just like in the videos.
My sister's hands were on top of me, and her legs were raised and
bent , just like the pose in the videos. She kept watching me nervously, occasionally glancing down at
the area where we were about to intercourse.
Although I was afraid of pain, after hearing my sister tell me to be patient, I didn't dare say a word, letting
my glans start thrusting and bumping against her vulva. But because neither of us had experience
, we couldn't find the entrance to penetrate or accommodate her.
At first, my sister didn't say anything, but later she kept asking me nervously how it was going, and I could only
answer that I couldn't get it in...
My sister seemed to breathe a sigh of relief, and then, not knowing what to do, asked me, "What should we do?"
At that moment, I really didn't know what to do, but suddenly I remembered what happened in the bathroom that night, and I said,
"Sis, do you want to stand on the floor and bend over with your butt sticking out? That way, it'll be fine."
That was the position where I had taken my virginity from my sister in the shower that day. Since I already had experience, I knew that
penetration wouldn't be a problem.
After hearing this, my sister thought for a while, then stood on the floor with her legs spread apart, bent her body forward, and
rested her hands on the bed, looking back at me.
I quickly stood behind my sister, grasped my penis, and leaned forward, soon pressing it against her vaginal opening
. My sister watched nervously. I placed my hands on her waist and began to thrust forward…
I was terrified of pain, but suddenly found it didn't. The first time it didn't go in, so I
adjusted and thrust forward again. I immediately felt my entire penis squeeze into her flesh, a slight stinging sensation mixed with
intense pleasure. My sister suddenly opened her mouth wide, as if about to scream.
My penis was quickly fully inserted into my sister's vagina, my lower abdomen even bumping
against A warm, pleasurable sensation emanated from my penis.
“Sister, it's in! It doesn't hurt! It feels so good!” I excitedly told her.
But my sister frowned and whispered, “It hurts so much…”
I was startled, unsure what to do, but my sister just told me not to move and turned her head back to look at
the bed.
A minute or two passed like this. I enjoyed the warmth of my sister's vaginal muscles while
remaining . Then she turned back to me, seemingly calmer, and said, "Try pulling your penis
out and then back in."
As soon as I pulled my penis out as she said, I felt an explosive pleasure again, but my sister quickly said
, "Don't move, it will still hurt."
So I dared not move again...
"It hurts so much..." my sister frowned at me, "But it didn't hurt this much last time..."
That night, we tried a few more times, but my sister still couldn't bear it, and in the end we had to
finish .
Although I didn't feel any dissatisfaction and even loved the feeling of penetrating my sister's anus, if I had any worries,
it was only that my sister would feel pain, but at least she didn't blame me.
From that day on, whenever my sister thought of it or was willing to try it, we would secretly
play sex games while taking a shower or before going to bed.
