Sister's breasts

Chapter 1 My Sister , Who

I Depend on for Life My name is Ma Xiaoshuai, I'm 16 years old, and a top student at Chongshi Junior High School. Because I'm smart and studious, my grades
have always been among the top three in my class, making me a favorite of my teachers. The entrance exams are coming up soon, and my goal is to get into
the best high school in the city—Xiangshan Senior High School. Getting into this high school means I've already stepped into the gates of
university .

"Xiaoshuai, you're back! Look, today I made your favorite braised crucian carp. Go wash
your hands and come eat!"

The one speaking loudly to me is my older sister, Ma Xiaoliang. Every day when I come home from school, my sister has already
prepared dinner for me. My sister is three years older than me. To support my schooling, she dropped out of junior high three years ago to work.
Our family is a working-class family. Three years ago, my father died in a traffic accident. My mother couldn't bear the loss of
my father , nor the burden and pressure of life, and a month later, she took medication and followed my father. Since then,
my sister and I have depended on each other for life. My sister now works at a supermarket during the day and tutors children at night. Oh
, I forgot to mention, my older sister is a better student than me. She wouldn't have dropped out of school if it weren't for me.

To support my education, she didn't have extra money for pretty clothes, so she dressed very simply, but that couldn't
hide her figure. I remember my mother was a great beauty, with snow-white skin, large breasts, and a round bottom.
I used to love snuggling up to her chest, feeling her firm curves. My sister is
a carbon copy of my mother; although her breasts haven't reached my mother's level yet, they're already a C-cup.

Actually, I was captivated by my sister's breasts three years ago. At that time, both my parents had passed away
, and I was only 13 years old.

"Sister, I'm scared. I want to sleep with you tonight."

"Little Shuai, you're so old now, you should sleep alone. Or, I can stay next to you and
go to sleep after you fall asleep."

"No. Before, when I was scared, Mom would hold me to sleep. Now, Mom is gone, and no
one loves me anymore." As I spoke, tears welled up in my eyes.

My sister thought of my parents and also shed tears, coming over to hug me. I leaned against my sister's chest;
it was so soft and warm. A change stirred within me. "Little Shuai, Mom and Dad are gone. Now it's just
the two of relying on each other. Don't be afraid, I'll sleep with you tonight."

That night, my sister held me close, my head resting on her arm, my face against her breast. In the middle of the night
, I vaguely felt a nipple near my mouth. I bit down and started sucking. My hand instinctively
reached for my sister's buttocks. My penis began to swell, feeling it press against my sister's thigh. I instantly woke
up. I squinted and saw my sister's eyes were closed. Suddenly, I grew bolder. I slipped my hand inside
her pajamas, touching the lower edge of her breast. Through her clothes, I sucked harder on her nipple.

"Ah, you little rascal, you bit me!" My sister cried out, her face flushed. I quickly
let go , releasing my grip and mouth, looking at my sister innocently like a child who had done something wrong. My sister didn't
scold me further, but turned away. But from then on, my sister never slept with me again. Even when I
begged, she would at most lie down beside me, wait until I fell asleep, and then go back to her room to sleep.
This . And I, in those three years, have grown tall and strong, becoming a handsome young man; my sister has also
matured, becoming more and more like our mother.

---Separation Line---

"Sister, I'm home." Today is Friday, tomorrow is a day off. As soon as class ended, I rushed home
. "Sister, are you home?" I called out to my sister as I changed my shoes. Not hearing a reply, I
felt a little strange. Usually, my sister would definitely be home at this time. I checked the shoe rack; all the shoes were there. I
was sure my sister hadn't gone out.

I pushed open my sister's door and saw her asleep, her face flushed. I quickly went to her window and
touched her forehead. It was so hot! My sister had a fever. I quickly grabbed a towel and placed it on her forehead.

"Little Shuai, you're back. I'm feeling a little unwell. There are noodles in the kitchen, make yourself some.
" My sister was woken up by me and spoke weakly.

"Sis, you're very hot. Have you taken any medicine? Should we go to the hospital?"

"Little Shuai, I'm fine, I've already taken some medicine, I'll be fine after a nap. Make yourself some noodles, don't
wake me, I'll be fine after a nap." After saying that, my sister turned over and went back to sleep.

After dinner, I went to my sister's room and saw that she was sleeping soundly. I gently stroked my sister's
hair . Oh, she was sweating a lot, it was sticky. I looked at my sister with pity, thinking that my sister was
working too hard because of me, that's why she had a fever. I fetched a basin of water, preparing to wipe the sweat from my sister's head. I carefully
wiped my sister's face and forehead, and my sister felt it, turned over, and lay on her back. Because she was hot, my sister
lifted the blanket a little. Wow, one button on my sister's pajamas was undone, revealing a patch of her snow-white breasts and
the faint outline of her pink areolas. So big, so white! My blood rushed to my head, and I thought of
that night three years ago.

"Let me wipe my sister's body; she's covered in sweat. No, she'll be angry. Last time I kissed her, and
she hasn't . She's my sister, it's okay, just wipe her, nothing else..." I
struggled with my thoughts. Ultimately, reason prevailed. I carefully began to unbutton my sister's pajamas, my
hands trembling with excitement, and I couldn't get it right for a long time. I composed myself and unbuttoned one, then the second. When I
unbuttoned the third, I saw my sister's perfect breasts, like two large, snow-white steamed buns, proudly
erect . Her nipples were the size of small peanuts, pink, and the areolas were small, less than the size of a one-yuan coin
. I observed them closely, afraid to wipe her, lest she wake up. My penis
had become rock hard without me even realizing it. I stroked it through my pants; it felt wonderful.

I lowered my head to observe my sister's breasts up close. I thought they were much more attractive than the pornographic pictures I'd seen online
, because they were large and white, and seemed to defy gravity, standing erect
. I thought of that night three years ago when I had the urge to kiss her. I looked at my sister; her breathing was even, and I knew
she was sleeping soundly. So I carefully stuck out my tongue and licked her nipple. It was slippery and
a little hard. I licked it again. My sister stirred and let out a soft moan. I was startled and quickly squatted down.
Under the bed. After a while, hearing no movement from my sister, I stood up again. I noticed that her breasts had become erect
and their color had deepened. I mustered my courage and took her nipple into my mouth. I didn't dare use too much force
, just gently circling my tongue around her nipple and gently sucking on the areola with my lips. My penis
became even harder, and I reached into my pants and pulled out my penis, gently stroking it.

After a while, I switched to her other breast and continued sucking, my hand movements becoming faster. My
pleasure grew stronger and stronger, and I tried my best not to make a sound. Finally, I couldn't hold back and ejaculated. It was so intense that
I didn't even have time to cover my first ejaculation with a towel, and a little semen shot onto my sister's breast.

I suddenly came to my senses and realized I had done something wrong. I quickly covered my sister with the blanket,
didn't button her clothes, didn't wipe the semen off her breast, grabbed a towel and a basin, and fled from her
room . I lay in bed, my mind wandering, worried that my sister would ignore me if she found out tomorrow morning, and hoping she wouldn't
discover anything. Lost in these thoughts, I finally fell asleep in the early hours of the morning.

---Separation Line---

"Little handsome boy, the sun's already high in the sky, why aren't you up?"

I opened my eyes and saw my smiling sister. She smiled so beautifully; it seemed she hadn't discovered
what I'd done last night. I smiled back at her: "It's a rare day off today, and you won't even let me get a good night's sleep?"

"You lazybones. I'm off today too, so you can come with me to climb Fragrant Hills.
I haven't ."

"You had a fever yesterday, and you want to go hiking today? Is that alright?"

"It's okay, I'm perfectly fine now. Look, I'm full of energy." With that
, she spun around and bounced a few times. Her breasts bounced along with them—so bouncy!

Hearing that I was going hiking with my sister, I sat up abruptly, threw off the covers, and prepared to get dressed and get out of bed.
However, I forgot the embarrassing sight every man experiences in the morning. My 15cm penis was pushing up my briefs
, with quite a few pubic hairs sticking out. My sister yelled and ran out. I blushed and quickly got
dressed.

After eating the delicious breakfast my sister had made, we set off to climb the mountain. About a 20-minute bus ride later,
we arrived at the foot of Fragrant Hills. "The air here is so fresh, Xiao Shuai. Do you remember when we last climbed together
?"

"Of course I remember. It was about half a year ago. I got first place in the class on my exam, and you
took hiking. Last time, you were out of breath halfway up, not as good as me, haha."

"Hmph, that was because I was too tired the day before. I rested for so long yesterday, so I definitely
won't . Okay, let's go."

With that, my sister rushed ahead of me and started climbing. Today, my sister was wearing a white tracksuit, the material
was nice , thin and light. I could see the outline of her underwear on her buttocks and the shape of her bra when I looked up.
In the sunlight, my sister's waist looked slender, and her hips were quite full—she had a model's figure.

"What are you standing there for, Xiao Shuai? Hurry up, or you

'll miss your sister!" "Just kidding, I won't miss you. Ma Xiaoliang, you wait, I'm coming for you!"

"You dare call my sister by her name? Don't you want to live? See how I deal with you later!"

Laughing and joking, we quickly reached the mountainside. The mountain air was wonderful; we stopped,
breathing in the fresh air, feeling incredibly comfortable. My sister and I had been slightly sweating from the climb; her
face was flushed, and there were faint beads of sweat on the tip of her nose, making her look exceptionally beautiful. Because she was a little out of breath, her
chest heaved. I thought of last night, and slowly, her clothes
disappeared . I saw bright red buds, adorning two large, white mounds, as if my sister were
calling out to me: "Xiao Shuai, what are you waiting for? Come on, come and eat my breasts!"

"You little devil, why are you staring at me like that?"

"Because you're pretty, sister." I snapped out of my daze and withdrew my lecherous gaze.
Chapter Two: Sister's Injury

(Continued from last time). We were almost at the summit when I suddenly felt the urge to pee. I said to my sister, "Sis, I need to pee.
Wait here for me, I'll be right back."

"Be careful, I'll just sit here and rest for a bit."

I followed a path into the woods. After about 50 meters, I saw no one around and
took out my penis, ready to ejaculate. Suddenly, I saw a corner of a red garment peeking out from under a large tree.
I was startled and withdrew my penis, thinking, "Luckily I haven't ejaculated yet. Maybe it's a woman there; otherwise,
it would be bad if someone saw me." I cautiously moved forward, wanting to see if anyone was there. I quietly
turned to the other side of the tree and saw a woman's figure. She looked young, around 17 or 18.
Upon closer inspection, I realized it was Liu Lili, our class monitor. I was just about to go over and say hello when I suddenly saw
Liu Lili lift her clothes and reach for her waistband.

Was she going to pee too? I quickly squatted down to avoid being seen. I saw Liu Lili unbuckle her belt and
slowly pull down her jeans, revealing a white cartoon underwear underneath. She pulled up her underwear and squatted down. Wow,
what a white butt! It was the first time I'd seen a real woman's butt, and it was from our beautiful class monitor. I stared wide-eyed
, afraid of missing a single moment. I saw quickly, a rapid stream of water
gushing , and I could vaguely see a small patch of darkness in front of her buttocks. Her buttocks looked exceptionally white
and shiny in the sunlight, and my penis, once again, became erect. Soon, the sound of the water subsided, Liu Lili
shook her buttocks a few times, pulled up her pants, and I could still vaguely see the wetness on her buttocks. She first pulled up
her shorts , then reached down and rubbed her crotch a couple of times before slowly pulling up her jeans. I waited until Liu Lili finished and
disappeared before taking out my penis and relieving myself.

"Little Handsome, why were you so slow? I thought something had happened to you, you scared me to death!"
Suddenly, my sister blushed. "Little Handsome, actually, I need to go too, could you keep watch for me?"

"What do you need? What do you mean by keeping watch?"

My sister blushed even more and shouted, "You silly Little Handsome, I just need to go to the toilet!"

"Oh, sister, please explain. Okay, I'll keep watch for you, no problem." I thought to myself,
I just saw the beautiful class monitor urinate, could I be about to see my sister urinate too?

"What are you thinking? Let me tell you, you're not allowed to peek at me while I'm peeing, or I won't talk to you anymore."

I followed behind my sister to a safe place. She said, "Little Shuai, turn around,
but you're only allowed to look that way. Don't turn back until I call you. Otherwise, I'll never talk to you again."

"Okay, sister, hurry up."

"What's the rush, you brat." After she finished speaking, I heard my sister unbuckling her belt and taking off her pants. I
really wanted to turn around and look, but I was afraid she would be angry and ignore me if she saw me, so I resisted the urge to turn around. After a while
, I heard the sound of peeing. The water was flowing very fast, similar to Liu Lili's peeing. It seemed my sister had been holding it in
for quite a while. The urine flowed onto the grass, making a pleasant sound. I closed my eyes and
quietly listened.

"Snake, there's a snake!" Just as I was engrossed in the sound of my sister's peeing, I suddenly heard her shout
. Hearing my sister's shout, I quickly turned around and saw a bluish snake, about two feet long, swiftly
slither into the woods and disappear. I noticed my sister's pants were still above her knees, and I saw
several red marks on the inside of her fair thighs—snake bite marks, I knew.

"Little Shuai, turn around, don't look!" My sister, not wearing pants, looked quite wolfish,
and kept telling me to turn back. At that moment, my mind was filled with images of people dying from snake bites, and
all I could think about was what would happen to my sister. I didn't even hear what my sister was muttering; I
rushed towards her like an arrow, not caring whether she wanted to or not, stripped off my clothes and spread them on the ground, picked her
up placed her naked on my clothes, spread her legs, and started sucking on her wound
.

I admit, I was very focused when I sucked, completely devoid of any evil thoughts, even forgetting to
admire the mysterious part of my sister's mouth; all I could think about was preventing anything from happening to her. After about four or five sucks, fearing I
hadn't cleaned it enough, I lowered my head again.

"Little handsome, if you keep sucking my blood, I'll drain you dry. I yelled so loudly to tell you to stop. That
snake is just a common little green snake, it's not poisonous."

I heard my sister's words, looked up, and saw her face was flushed. Following her gaze, I
saw her snow-white thighs and a patch of black between them. I'm not kidding, I didn't see
my sister's most mysterious place because she had subconsciously closed her thighs, blocking the mysterious opening, only
a dark patch of hair was visible. My sister's hair wasn't too much, but it wasn't a little either, jet black and shiny, with a good sheen,
and it was very beautiful.

"You little handsome rascal, what are you looking at? Turn around right now!" With a flick on the forehead, my sister shouted
for me to turn around immediately. My face turned red, and I quickly turned around. My sister quickly put on her pants, and when I turned back
, I saw that her face was still red, pink and tender, very beautiful.

"Sister, your thighs are so white, they almost made my eyes water." I
said this to my sister in a joking tone, trying to break the awkwardness. My sister glared at me and said, "You still dare
to talk back you didn't even hear me. But since you were so worried about me, I won't blame you. Humph,
no guy has ever seen my body before, and you're the first one to see it, you little rascal."

"Sister, I swear, I was just focused on sucking and didn't look closely at all."

"You little rascal, you want to look closely? You're asking for it."

Seeing my sister pretending to hit me, I quickly turned and left. My sister chased after me. Soon
, we reached the top of the mountain. It was a bit windy at the top, so I took off my coat and put it on my sister, afraid
she catch a cold, because she had a fever last night.

"Ma Xiaoshuai, hey, I'm going to tell the teacher that someone so young is dating."

Looking in the direction of the voice, I saw it was the beautiful class monitor, Liu Lili. "Yeah, help me see
if my girlfriend is pretty?" As I spoke, I hugged my sister tightly. Her face was still red, and she looked at me suspiciously, not knowing what I was up
to .

"This is my classmate, and also our class monitor, Liu Lili. Class Monitor Liu, isn't my girlfriend
prettier than you?" Thinking about how I'd just seen Liu Lili urinate, her snow-white
buttocks flashed before my eyes, and a lewd smile crept across my face.

"Ma Xiaoshuai, why are you staring at me like that? I'm warning you, your girlfriend likes you, but I don't
. If you have any improper thoughts about me, you'll be in big trouble. If you don't want me to tell
the teacher, you'd better say some nice things and do things I like, otherwise, hmph."

I leaned close to Liu Lili's ear and whispered a few words. Liu Lili's face turned bright red, and she shyly
cursed, "You damn Ma Xiaoshuai, I hate you so much!" After saying that, Liu Lili turned and walked away.

"Hey, I'm his sister, not his girlfriend, don't listen to Xiaoshuai's nonsense." Hearing this,
Liu Lili turned back and glanced at me before quickly walking away.

"What did you say to her just now? Why did she leave as soon as you said it?"

"I lied and said I saw her reading a novel while studying yesterday, and she actually believed me, haha."

"You little devil, don't bully girls. Girls should be cared for. Okay, we should
go back now ."

---Separation Line---

Back home, I went to the bathroom. After coming out, I wanted to ask my sister what we were having for lunch, but she wasn't in
the living room, so I pushed open her bedroom door. "Sister, what are we having for lunch?" Before I could finish speaking
, I heard my sister scream. She quickly covered her breasts with her hands. It turned out she was
changing clothes, but her delicate hands couldn't cover her full breasts at all; her breasts were pressed against her hands,
creating a deep cleavage. She was wearing only a small white pair of panties, and I could vaguely see a
shadow below.

"You little devil, why didn't you knock before coming in? Get out of here, your sister is changing."

"What are you afraid of? It's not like I haven't seen it before. " "I muttered to myself and left the room. But my sister
looked really good standing there half-naked. Her legs were straight and long, dazzlingly white, and her breasts were large and firm, very alluring.
I've always wondered how my sister, who seems so petite, could have such large breasts; I guess she inherited them from
my mother. I remember when I was little, I would bathe with my mother when I was 10. Every time in the bathtub, I would sit on my mother's..."
My back was pressed against my mother's breasts, and it felt very comfortable. Occasionally, I would sit behind her and reach out
to touch her large breasts. Each time, my mother would scold me, "Little boy, you're so big now, you're not allowed
to touch Mommy's breasts anymore. Mommy will be angry!" Despite her words, I would still touch her breasts every time. Each
time , I could feel her nipples getting bigger and harder. I remember asking her why, and she told
me that nipples get bigger and harder when stimulated. However, I never tried sucking on my mother's nipples
because I thought it was too embarrassing for someone my age to suckle. Now, I think that if I had wanted to
suckle , my mother certainly wouldn't have scolded me. But my mother is gone, and I'll never have
that opportunity again. My older sister really looks like my mother; her breasts are even more beautiful than hers, and my sister
doesn't know that I've already suckled on her breasts.

"You little devil, what are you laughing at all by yourself here for? It's time to eat." My sister's voice pulled me
back to reality from my reverie. Looking at her annoyed expression, I felt incredibly happy.

Chapter Three: My First Kiss

. It was Monday again. I lazily crawled out of bed, ate the loving breakfast my sister had prepared, and
then grabbed my backpack to go to school. Before leaving, I said goodbye to my sister as usual: "Sis, I'm off!"

I hopped on my bicycle and quickly arrived at school. Looking at the time, wow, less than ten minutes before class started!
I quickly parked my bike, went into the classroom, and sat down in my seat. "Good morning, Wang Hongyu."

"Ma Xiaoshuai, look who I am! Don't shout like that."

"Liu Lili, it's you? Where's Wang Hongyu?"

"Shh, I told the teacher I switched seats with her. You know, the principal is my aunt, and she listens to me the most
. What you saw on the mountain the other day, don't tell anyone. I'm sitting here to keep an eye on you, or
you'll be sorry."

I looked at Liu Lili; she was prettier than Wang Hongyu. Oh well,
it's good to have a prettier girl sit with me. She's the class monitor and has good grades, so it'll definitely help my studies. I teased her deliberately, "Don't
threaten me. If you don't give me something in return, I can't guarantee I won't tell."

"What do you want in return?"

"I want you to be my girlfriend." I blurted out, looking smugly at Liu Lili, thinking she
wouldn't know what to do now.

"Okay, I'll do it." Liu Lili bit her lip, remained silent for a while, as if she had
made , and answered me softly. Just then, the teacher came in and class began.

---Separation Line---

"Liu Lili, wait a minute." As soon as class ended, I saw Liu Lili quickly pack her bag, ready to leave
, and I quickly called out to her.

"What? I need to hurry home."

"What kind of tone is that? You need to know that you're my girlfriend now. How can you leave alone? At least
I should walk you home." I whispered in Liu Lili's ear. Liu Lili blushed and glared at
me fiercely: "Then hurry up."

Liu Lili's house is actually not far from mine, and it's on my way. But she usually walks faster, and I
like to joke around with my friends before leaving, so we rarely bump into each other on the road. She usually walks to and from school, while I
ride my bicycle. When I pushed my bicycle next to Liu Lili, I gestured with my lips, indicating that she should sit on it.
Liu Lili looked around and saw no one she recognized, then reluctantly sat on it. I started to walk, and Liu Lili called
out, quickly grabbing my waist. I could clearly feel Liu Lili's greatness on my back.

As we started to ride, I deliberately braked suddenly, and Liu Lili bumped into me again. Once again, I felt the full force of
her chest. I turned around and smiled; "Didn't know my girlfriend wasn't flat-chested!"

I immediately paid the price for that remark. Liu Lili pinched my thigh hard:
"Serves you right for talking nonsense. Ride your bike properly, or I'm getting off."

We soon arrived at Liu Lili's building. She got off her bike and prepared to leave without a word. I stopped her,
half-jokingly saying, "Since she's your girlfriend, I remember in movies it's always like this—after dropping you off,
they're reluctant to part, and they have to kiss before you leave."

"You, you're such a bad guy, bullying me!" Liu Lili turned around, looked at me, and blinked her eyes
: "Okay, just one kiss." Then she brought her lips to my mouth. Seeing that Liu Lili was serious, I went
for it .

"Ouch, you little brat, Liu Lili, that hurts!" Just as my lip
was less than a centimeter from Liu Lili's cherry-like lips, she quickly bit my lip, then turned and ran inside.
Halfway inside, she turned back to look at me, smiling brightly. This girl is really cute. I touched my bitten
lip, but felt surprisingly good.

---Separation Line---

"Sister, what's wrong? Who bullied you?" When I got home, I saw my sister sitting on the sofa,
sobbing , looking very sad. I quickly went over and supported her shoulders, asking what had happened
.

My sister wiped away her tears, looked at me, forced a few smiles, and said, "I'm fine, I just thought of
Mom and Dad. I'm okay now, I'll go cook, you wait, it'll be ready soon."

Looking at my sister's slightly red eyes and the tear stains on her face, I couldn't help but gently put
my arm around her shoulder and kiss her cheek. My sister didn't refuse me. I kissed her, looking intently
at her luscious lips. Unable to control my emotions, I pressed my lips to hers.
Her lips might have been wet with tears; they tasted slightly salty. I held her lips in my mouth, my tongue
slowly darting out, tasting the tears. Her body visibly trembled, then she went
limp in my arms, closing her eyes.

I greedily sucked on her lips, slowly trying to slip my tongue into her mouth. At
first resisted, but slowly, her defenses crumbled, and she slightly opened her mouth. I immediately felt
a faint fragrance waft from her mouth, and my tongue took over. I tentatively
explored my tongue, sometimes probing deeply, trying to embrace her tongue. Her breathing
became noticeably rapid, and gradually her tongue moved closer to mine, until slowly our tongues met. So warm...
The warmth was in my eyes as I greedily sucked on my sister's nectar. She instinctively hugged me tighter. My
blood was already rushing to a certain point, my penis throbbing painfully. My hands, acting on their own, began
to caress my sister's body, slowly climbing to her breasts—so big and firm. My mouth continued to suckle
, my hands stroking her breasts from bottom to top. Even through her shirt and bra, I could feel
her nipples, proudly erect. My sister's breathing became more rapid, her chest heaving, her legs
wriggling uncontrollably, her hands gripping my back tightly. I wrapped one hand around her back,
slowly sliding down to her full, round buttocks. Her buttocks were perky and incredibly elastic; even
through two layers of pants, I could feel their slipperiness. My penis was rock hard, and reason was
gradually fading from my mind. My hand slid down my sister's lower abdomen, slipping inside her panties and touching
her not-so-lush pubic hair. Suddenly, my sister snapped out of it and pushed me away forcefully. "Xiaoshuai, we can't
do this Let go of me!"

My eyes were red. Seeing her push me away, I looked at her again, then tried to lunge at her. "Slap!"
My sister slapped me across the face. I froze for a moment, then realized what had happened
. I quickly turned and went into my room, locking the door. My sister had never hit me before,
not even in the years since our parents left.

"Xiaoshuai, listen to me. I didn't mean to hit you. I just wanted you to come to your senses. We're
siblings, we can't do this. Xiaoshuai, open the door, please let me explain." My sister thought I
was angry and comforted me from outside the door.

Hearing her voice outside, tears streamed down my face. Actually, I didn't blame my sister for hitting me; I
blamed myself for doing such a despicable thing to my sister. She's my sister, she's so beautiful,
how could I defile her? But I kept trying to molest my sister. Last time I even ejaculated on her
breasts , and I don't know if she even noticed. This time I even reached out and touched her private parts. I've gone too far
.

"Little handsome, open the door. At most, I'll agree to it because you're in puberty and
curious . As long as you don't go too far, I'll agree to it, okay? Little handsome, open the door.
" My sister continued calling from outside the door when I didn't speak.

My sister was willing to sacrifice herself for me like this. I slapped myself a few times, opened the door, and
threw her arms. "Sis, I didn't mean to do this, but I couldn't control myself. Hit me, scold
me."

"Silly little brother, your sister is so willing to hit you and scold you. Does your face still hurt? Xiaoshuai, I know you like your sister
, and your sister likes you too, but we are siblings, we can't do anything too outrageous, you know? Your sister
knows Xiaoshuai has grown up and is curious about the opposite sex, and wants to have a girlfriend, right? You just
stole my first kiss, do you know that? You even dared to touch my breasts here, my breasts have never been touched by a stranger before
."

"Sister, you are so beautiful." I looked at my sister and answered her dreamily.

My sister looked at me, as if she had made a great decision, and said, "Sister knows you are curious about the opposite sex.
Sister promises you, you can find a girlfriend. If you really can't find one, as long as you don't go too
far with your sister, there are some things that sister can promise to do for you."

"Sis, I have a girlfriend." I said proudly to my sister.

The smile on her sister's face vanished instantly, then she smiled again and said, "Little brother, you have a girlfriend? When did
this happen? Did you two do anything?"

"Sis, it's that girl we met while hiking last time, her name is Liu Lili."

"Oh, that girl is quite pretty." The sister said with a hint of jealousy, "Remember last time she
thought I was your girlfriend and was about to tell the teacher? How did she become your girlfriend? What are you up to
?"

"She just agreed to be my girlfriend today. Sis, do you want to know why she agreed to be my girlfriend?" "Yes, I want to know.
" " Then you have to kiss me." "You little devil, no way! If you don't tell me, I won't talk to you anymore." " Ah , I surrender, sister, I'll tell you, okay? " "You said I told her she's pretty?" "Of course your sister is pretty." Chapter One: My Sister Who Depends on Me My name is Ma Xiaoshuai, I'm 16 years old, and a top student at Chongshi Junior High School. Because I'm smart and studious, my grades have always been among the top three in the class, and I'm deeply loved by my teachers. The high school entrance exams are coming up soon, and my goal is to get into the best high school in the city—Xiangshan High School. Getting into this high school means I've already stepped into the gates of university . "Xiaoshuai, you're back! Look, I made your favorite braised crucian carp today. Go wash your hands and eat!" The one speaking loudly to me is my older sister, Ma Xiaoliang. Every day when I come home from school, my sister has already prepared dinner for me. My sister is three years older than me. To support my education, she dropped out of school three years ago after graduating from junior high to work. Our family is a working-class family. Three years ago, my father died in a traffic accident. My mother couldn't bear the blow of losing my father , nor the burden and pressure of life, and a month later, she took medication and followed my father. Since then, my sister and I have depended on each other. My sister now works at a supermarket during the day and tutors children at night. Oh , I forgot to mention, my sister is a better student than me; she wouldn't have dropped out of school if it weren't for me. To support my education, my older sister didn't have much money to buy pretty clothes, so she dressed very simply, but it couldn't hide . I remember my mother was a great beauty, with snow-white skin, large breasts, and a round bottom. I used to love snuggling up to her chest, feeling her firmness. My sister is a carbon copy of my mother; although her breasts haven't reached my mother's level yet, they're already a C cup. Actually, I was captivated by my sister's breasts three years ago. At that time, both my parents had passed away , and I was only 13 years old. "Sister, I'm scared. I want to sleep with you tonight." "Little Shuai, you're so big now, you should sleep alone. Or, I'll stay next to you and wait until you fall asleep before I go to sleep with you."

"No. Before, when I was scared, Mom would hold me to sleep. Now, Mom's gone, and no
one loves me anymore." As I spoke, tears welled up in my eyes.

My sister, thinking of our parents, also shed tears and came over to hug me. I leaned against my sister's chest; it
was so soft and warm. A change began to stir within me. "Little Shuai, Mom and Dad are gone. Now it's just
the two of relying on each other. Don't be afraid, I'll sleep with you tonight."

That night, my sister held me, my head resting on her arm, my face against her breast. In the middle of the night
, I vaguely felt a nipple near my mouth. I bit down and started sucking. My hand naturally
reached for my sister's buttocks. My penis began to swell, and I felt it pressing against my sister's thigh. I suddenly
woke up. I squinted and saw that my sister's eyes were closed. Suddenly, I became bolder. I reached inside
my sister 's pajamas and touched the lower edge of her breast. Through her clothes, I sucked on her nipple with increasing force.

"Ouch, you little rascal, you bit me!" My sister cried out, her face flushed. I quickly
let go of her hand and mouth, looking at her innocently like a child who had done something wrong. My sister didn't continue
to scold me, but turned away. However, from then on, my sister never slept with me again. Even if I
begged, she would at most lie down next to me, wait for me to fall asleep, and then go back to her room to sleep.
This . And I, in those three years, have grown tall and strong, becoming a handsome young man; my sister has also
matured more and more, becoming more and more like our mother.

---Separation Line---

"Sis, I'm home." Today is Friday, tomorrow is a day off. As soon as class ended, I rushed home
. "Sis, are you home?" I called out to my sister as I changed my shoes. I didn't hear a reply from my sister, which
felt a little strange. Usually, my sister would definitely be home at this time. I looked at the shoes on the shoe rack; they were all there. I
was sure my sister hadn't gone out.

I pushed open my sister's door and saw her asleep, her face flushed. I rushed to her window and
touched her forehead—it was burning hot! She had a fever. I quickly grabbed a towel and placed it on her forehead.

"Xiaoshuai, you're back. I'm not feeling well. There are noodles in the kitchen; make yourself some.
" My sister was woken up by me and spoke weakly.

"Sis, you're very hot. Have you taken any medicine? Should we go to the hospital?"

"Xiaoshuai, I'm fine. I've already taken medicine. I'll be fine after a nap. Make yourself some noodles. Don't
wake me; I'll be fine after a nap." After saying that, my sister turned over and continued sleeping.

After dinner, I went to my sister's room and saw her sleeping soundly. I gently stroked her
hair ; oh dear, she was sweating a lot, it was sticky. I looked at her with pity, thinking, "She's doing this all because of me
; she's been working too hard, that's why she has a fever." I fetched a basin of water, intending to wipe the sweat from her head. I carefully
wiped my sister's face and forehead. She seemed to sense it, turned over, and lay on her back. Because she was hot, she
lifted the blanket a little. Wow, one button on her pajamas was undone, revealing a patch of her snow-white breasts, and
I could vaguely see her pink areolas. So big, so white! My blood rushed to my head, and I thought of
that night three years ago.

"Let me wipe my sister's body; she's covered in sweat. No, she'll be angry. Last time I kissed her, and she
hasn't . She's my sister, it's okay, just wipe her, nothing else..." I
struggled with my thoughts. Finally, reason prevailed. I carefully began to unbutton my sister's pajamas. My
hands trembled violently with excitement, and I couldn't unbutton them for a long time. I composed myself and unbuttoned one, then the second. When I
unbuttoned the third, I saw my sister's perfect breasts, like two large, snow-white steamed buns, proudly
erect . Her nipples were the size of small peanuts, pink, and the areolas were small, less than the size of a one-yuan coin
. I observed carefully, afraid to wipe my sister, lest she wake up. My penis
had become rock hard, and I stroked it through my pants; it felt good.

I lowered my head to observe my sister's breasts up close. I thought they were much more beautiful than the pornographic pictures I'd seen online
, because they were large and white, and seemed to defy gravity, standing tall and erect
. I thought of that night three years ago when I had the urge to kiss her. I looked at my sister; her breathing was even, and I knew
she was sleeping soundly. So I carefully stuck out my tongue and licked her nipple. It was slippery and
a little hard, so I licked it again. My sister stirred and let out a soft moan. I was startled and quickly
crouched down the bed. After a while, when I heard no movement from my sister, I stood up again. I noticed that my sister's breasts had
become erect and their color had deepened. I mustered my courage and took my sister's nipple into my mouth. I didn't dare use too much force
, just gently circling my tongue around her nipple and gently sucking on the areola with my lips. My penis
grew even harder. I reached into my pants and pulled it out, gently stroking it.

After a while, I switched to my sister's other breast, continuing to suckle, my hand movements quickening. My
pleasure intensified, and I tried my best to remain silent. Finally, I couldn't hold back and ejaculated. It was so intense that
I didn't even have time to cover my first ejaculation with a towel; a little semen landed on my sister's breast.

I suddenly snapped back to reality, realizing I had done something wrong. I quickly covered my sister with the blanket,
not even buttoning her clothes or wiping the semen from her breast. I grabbed a towel and a basin and fled her
room . Lying in bed, I thought wildly, worried that my sister would ignore me if she found out the next morning, and hoping she wouldn't
discover it. I drifted off to sleep in this state of mind until the early hours of the morning.

---Separation Line---

"Little handsome, the sun's already high in the sky, why aren't you up?"

I opened my eyes and saw my smiling sister. She smiled so beautifully; it seemed she hadn't discovered
what I'd done last night. I smiled at her: "It's a rare day off, and you won't even let me get a good night's sleep?"

"You lazybones. I'm off today too, so you can come with me to climb Fragrant Hills.
I haven't ."

"You had a fever yesterday, and you want to go hiking today? Is that alright?"

"It's okay, I'm perfectly fine now. Look, I'm full of energy." After saying that
, she spun around and bounced a few times. Her breasts bounced along with her; they were so bouncy.

Upon hearing that I was going hiking with my sister, I immediately sat up, threw off the covers, and prepared to get dressed.
However, I forgot the embarrassing sight every man experiences in the morning; my 15-centimeter penis was pushing up my briefs
, with quite a few pubic hairs sticking out. My sister yelled and ran out. I blushed when I saw this and hurriedly got
dressed.

After eating a delicious breakfast made by my sister, we set off for the hike. After about a 20-minute bus ride,
we arrived at the foot of Fragrant Hills. "The air here is so fresh, Xiao Shuai. Do you remember when we last hiked together
?"

"Of course I remember. It was about half a year ago. I got first place in the class on my exam, and you
took hiking. Last time, you were panting halfway up, not as good as me, haha."

"Hmph, that was because I was too tired the day before. I rested for so long yesterday, so I definitely
won't . Okay, let's go."

With that, my sister rushed ahead of me and started climbing. Today, my sister wore a white tracksuit; the fabric
was nice , thin and light. I could see the outline of her underwear on her buttocks and the shape of her bra when I looked up.
In the sunlight, her waist looked very slender, and her buttocks were quite full—she had a model's figure.

"What are you standing there for, Xiao Shuai? Hurry up, or you won't be able to catch up with me!"

"Just kidding, I won't catch you. Ma Xiaoliang, you wait, I'm coming after you!"

"You dare call me by my name? Don't you want to live? See how I deal with you later!"

Laughing and joking, we quickly reached the mountainside. The mountain air was wonderful; we stopped,
breathing in the fresh air, feeling very comfortable. My sister and I had been slightly sweaty from the climb; her
cheeks were rosy, and there were faint beads of sweat on the tip of her nose, making her look exceptionally beautiful. Because she was a little out of breath, my sister
's chest heaved. I thought of last night, and slowly, her clothes
disappeared . I saw bright red nipples, adorning two large, white mounds. It was as if I could see my sister
calling out to me: "Little handsome, what are you waiting for? Come on, come and eat my breasts!

" "You little rascal, why are you looking at me like that?"

"Because you're pretty, sister." I snapped out of my daze and withdrew my lecherous gaze.
Chapter Two: Sister Injured (

Continued from last time). We were almost at the top of the mountain when I suddenly felt the urge to urinate. I said to my sister, "Sis, I need to pee.
Wait here for me, I'll be right back."

"Be careful, I'll just sit here and rest for a bit."

I followed a path into the woods. After about 50 meters, I saw that no one was around, so I
took out my penis, ready to ejaculate. Suddenly, I saw a corner of a red garment peeking out from under a large tree ahead.
Startled, I withdrew my penis, thinking thankfully it hadn't ejaculated yet. Maybe it was a woman over there; otherwise,
I'd be in trouble if someone saw me ejaculating. I cautiously moved forward, wanting to see if anyone was there. I quietly
turned to the other side of the big tree and saw a woman's figure. She looked young,
around 17 or 18. Upon closer inspection, it was our class monitor, Liu Lili. I was about to go over and say hello when I suddenly saw
Liu Lili lift her clothes and reach for her waistband.

Was she going to urinate too? I quickly squatted down to avoid being discovered. I saw Liu Lili unbuckle her belt and
slowly pull down her jeans, revealing a white cartoon underwear underneath. She pulled down her underwear and squatted down. Wow,
such a white butt! It was the first time I'd seen a real woman's butt, and it was from our beautiful class monitor. I stared wide-eyed
, afraid of missing a single moment. I saw quickly, a rapid stream of water
gushing , and I could vaguely see a small patch of darkness in front of her buttocks. Her buttocks shone brightly in the sunlight
, and my penis, once again, defiantly sprang to life. Soon, the sound of the water subsided. Liu Lili
jiggled her buttocks a few times, pulled up her pants, and I could still vaguely see the wetness on her buttocks. She first pulled up
her shorts , then rubbed her crotch a couple of times before slowly pulling up her jeans. I waited until Liu Lili finished
and disappeared before pulling out my penis and relieved myself.

"Little Handsome, why were you so slow? I thought something had happened to you, you scared me to death!"
Suddenly, my sister blushed. "Little Handsome, actually, I need to go too, can you keep watch for me?"

"What do you need? What do you mean by keeping watch?"

My sister blushed even more and shouted, "You silly Little Handsome, I just need to go to the toilet!"

"Oh, sister, please be clear. Okay, I'll keep watch for you, it's my duty." I thought to myself,
I just saw the beautiful class monitor urinate, could I be about to see my sister urinate too?

"What are you thinking? Let me tell you, you're not allowed to peek at me while I'm peeing, or I won't talk to you anymore."

I followed behind my sister to a safe place. She said, "Little Shuai, turn around,
but you're only allowed to look that way. Don't turn back until I call you. Otherwise, I'll never talk to you again."

"Okay, sister, hurry up."

"What's the rush, you brat." After she finished speaking, I heard my sister unbuckling her belt and taking off her pants. I
really wanted to turn around and look, but I was afraid she would be angry and ignore me if she saw me, so I resisted the urge to turn around. After a while
, I heard the sound of peeing. The water was flowing very fast, similar to Liu Lili's peeing. It seemed my sister had been holding it in
for quite a while. The urine flowed onto the grass, making a pleasant sound. I closed my eyes and
quietly listened.

"Snake, there's a snake!" Just as I was engrossed in the sound of my sister's peeing, I suddenly heard her shout
. Hearing my sister's shout, I quickly turned around and saw a bluish snake, about two feet long, swiftly
slither into the woods and disappear. I noticed my sister's pants were still above her knees, and I saw
several red marks on the inside of her fair thighs—snake bite marks, I knew.

"Little Shuai, turn around, don't look!" My sister, not wearing pants, looked quite wolfish,
and kept telling me to turn back. At that moment, my mind was filled with images of people dying from snake bites, and
all I could think about was what I would do if something happened to my sister. I didn't even hear what my sister was muttering; I
rushed towards her like an arrow, not caring whether she wanted to or not, stripped off my clothes and spread them on the ground, picked her
up , placed her naked on my clothes, spread her legs, and started sucking on her wound
.

I admit, I was really focused when I was sucking, completely without any evil thoughts, and even forgot...
Admiring the mysterious spot on my sister's lips, all I could think about was preventing anything from happening to her. After sucking for about four or five times, I was afraid
I hadn't sucked enough, so I lowered my head again.

"Little handsome, if you keep sucking my blood, I'll drain you dry. I'm yelling so loudly to tell you to stop. That
snake is just a common little green snake, it's not poisonous."

I heard my sister's words, looked up, and saw that her face was flushed. Following her gaze, I
saw her snow-white thighs and a patch of black between them. I'm not lying, I didn't see
my sister's most mysterious place because she had subconsciously closed her thighs, blocking the mysterious opening, only
a dark patch of hair was visible. My sister's hair wasn't too much, but it wasn't a little either, jet black and shiny, with a good sheen,
and it was very beautiful.

"You little handsome rascal, what are you looking at? Turn around right now!" With a sharp rap on the head, my sister shouted
for me to turn around immediately. My face turned red, and I quickly turned around. My sister quickly pulled up her pants, and when I turned back
, I saw that her face was still red, pink and tender, very beautiful. "Sister, your thighs are so white! They almost made my eyes water." I said this

to my sister jokingly , trying to break the awkwardness. My sister glared at me and said, "You still dare to talk back? I'm so loud to you, you didn't even hear me. But since you were so worried about your sister, I won't blame you. Humph, no one of the opposite sex has ever seen my body before, and who knew the first one to see it would be you, you little rascal." "Sister, I swear, I was just focused on sucking on it, I didn't look closely at all." "You little rascal, you want to look closely? You're asking for it." Seeing my sister pretending to hit me, I quickly turned and left. My sister chased after me. Soon , we reached the top of the mountain. It was a bit windy at the top, so I took off my coat and put it on my sister, afraid she would catch a cold, because she had a fever last night. "Ma Xiaoshuai, oh my god, I'm going to tell the teacher that someone so young is dating." Looking in the direction of the voice, I saw it was the beautiful class monitor, Liu Lili. "Yeah, help me see, isn't my girlfriend pretty?" I said, pulling my sister into my arms. Her face was still flushed; she looked at me suspiciously, wondering what I was up to . "This is my classmate, and also our class monitor, Liu Lili. Class Monitor Liu, isn't my girlfriend prettier than you?" Thinking about how I'd just seen Liu Lili urinate, her snow-white buttocks flashed before my eyes, and a lewd smile crept across my face. "Ma Xiaoshuai, why are you staring at me like that? I'm warning you, your girlfriend likes you, but I don't . If you have any improper thoughts about me, you'll be in big trouble. If you don't want me to tell the teacher, you'd better say some nice things and do things I like, otherwise, hmph." I whispered a few words in Liu Lili's ear. Her face turned bright red, and she said shyly, "You jerk, Ma Xiaoshuai, I hate you!" Then, Liu Lili turned and left. "Hey, I'm his sister, not his girlfriend. Don't listen to Xiaoshuai's nonsense." Hearing this, Liu Lili turned around, glanced at me, and quickly walked away. "What did you just say to her? Why did she leave as soon as you said it?" "I lied and said I saw her reading a novel while studying yesterday, and she actually believed me, haha." "You naughty Xiaoshuai, don't bully girls. Girls should be cared for. Okay, we should go back ." ---Separation Line--- Back home, I went to the bathroom. After coming out, I wanted to ask my sister what we were having for lunch, but seeing that she wasn't in the living room, I pushed open her bedroom door. "Sister, what are we having for lunch?" Before I could finish speaking , I heard my sister scream. She quickly covered her breasts with her hands. She was changing clothes, but her delicate hands couldn't cover her full breasts at all; they were pressed together a deep cleavage. She was wearing only a small white pair of panties, and I could vaguely see a shadow beneath. "You little devil, why didn't you knock before coming in? Get out of here, I'm changing." "What are you afraid of? It's not like I haven't seen it before. " "I muttered to myself and left the room. But my sister looked really good standing half-naked. Her legs were straight and long, dazzlingly white, and her breasts were large and firm, very alluring. I've always wondered how my sister, with her seemingly petite body, could have such large breasts; I guess she inherited them from my mother. I remember when I was little, around 10 years old, I would bathe with my mother. Every time in the bathtub, I would sit in front of her, my back against her breasts, which felt very comfortable. Occasionally, I would sit behind her and reach out to touch her large breasts. Every time, my mother would scold me: 'Little boy, you're so big now, you're not allowed to touch Mommy's breasts anymore. Mommy will be angry.'" "Despite saying that, I still touch my mother's breasts every time. Every time , I can feel my mother's nipples getting bigger and harder. I remember asking my mother why, and she told me that nipples get bigger and harder when stimulated. But I never tried sucking on my mother's nipples because I thought it was too embarrassing for someone my age to suckle. Now that I think about it, if I had wanted to suckle my mother 's breasts, my mother definitely wouldn't have really scolded me. But my mother is gone, and I will never have that opportunity again. But my sister really looks like my mother, and her breasts are even more beautiful than my mother's. And my sister doesn't know that I have already suckled on her breasts. "You little devil, what are you laughing at by yourself here? It's time to eat." My sister's shout pulled me from my memories to reality. Looking at my sister's angry face, I felt particularly happy. Chapter 3 My First Kiss It was Monday again. I lazily got out of bed in the morning, ate the loving breakfast prepared by my sister, and carried my schoolbag to school. Before leaving, I said goodbye to my sister as usual: "Sis, I'm leaving." " I hopped on my bike and arrived at school quickly. Looking at the time, wow, less than ten minutes before class started! I quickly parked and went into the classroom, taking my seat. 'Good morning, Wang Hongyu.' 'Ma Xiaoshuai, look who I am! Stop calling me that!' 'Liu Lili, it's you! Where's Wang Hongyu?' 'Shh, I told the teacher I switched seats with her. You know, the principal is my aunt, and she listens to me the most . What you saw on the mountain the other day, don't tell anyone. I'm sitting here to keep an eye on you, or you'll be sorry.'"

I glanced at Liu Lili; she was prettier than Wang Hongyu. Oh
well, it's good to have a prettier girl sit with me. She's the class monitor and her grades are good, so it'll definitely help my studies. I teased her deliberately, "Don't
threaten me. If you don't give me something in return, I can't guarantee I won't tell."

"What do you want in return?"

"I want you to be my girlfriend." I blurted out, looking smugly at Liu Lili, thinking she
wouldn't know what to do now.

"Okay, I'll do it." Liu Lili bit her lip, remained silent for a moment, as if she had
made , and answered me softly. Just then, the teacher came in and class began.

---Separation Line---

"Liu Lili, wait a minute before you leave." As soon as class ended, I saw Liu Lili quickly pack her bag, ready to leave
, and I quickly called out to her.

"What? I need to get home quickly."

"What kind of tone is that? You need to know that you're my girlfriend now. How can you leave alone? At least
I should see you off." I whispered in Liu Lili's ear. Liu Lili blushed and glared at me fiercely
: "Then hurry up!"

Liu Lili's house wasn't far from mine, and it was conveniently on my way. But she usually walked faster, while I
liked to joke around with my friends before leaving, so we rarely bumped into each other on the road. She usually walked to and from school, while I
rode my bicycle. When I pushed my bicycle next to Liu Lili, I gestured with my lips for her to sit on it.
Liu Lili looked around to make sure no one she knew was there, and reluctantly got on. I started to move, and Liu Lili cried
out, quickly grabbing my waist. I could clearly feel the size of Liu Lili's breasts on my back.

After a while, I deliberately braked, and Liu Lili bumped into me again, once again feeling the force of
her chest. I turned around and smiled; "Didn't realize my girlfriend wasn't flat-chested!"

I immediately paid the price for that remark. Liu Lili pinched my thigh hard:
"Serves you right for talking nonsense. Ride your bike properly, or I'm getting off." We

soon arrived at Liu Lili's building. She got off her bike and prepared to leave without saying a word. I stopped her,
half-jokingly saying, "Since she's your girlfriend, I remember it's always like this in the movies. When you drop her off at her building,
they're reluctant to part, and they have to kiss before she leaves."

"You, you're such a bad guy, bullying me." Liu Lili turned around, looked at me, and blinked her eyes
: "Okay, just one kiss." After saying that, she brought her lips closer. I saw that Liu Lili was serious, so I went
for it and offered my lips.

"Ouch, you little rascal, Liu Lili, that hurts!" Just as my lips
were less than a centimeter from Liu Lili's cherry-like lips, Liu Lili quickly bit my lip, then turned and ran inside.
Halfway inside, she turned back to look at me, smiling brightly. "This girl is really cute," I thought, touching my sore
lip, but feeling surprisingly good inside.

---Separation Line---

"Sister, what's wrong? Who bullied you?" When I got home, I saw my sister sitting on the sofa,
sobbing , looking very upset. I quickly went over and supported her shoulders, asking what had happened
.

She wiped away her tears, looked at me, forced a smile, and said, "I'm fine, I just missed
Mom and Dad. It's okay now, I'll go make dinner, you wait, it'll be ready soon."

Looking at her slightly red eyes and the tear tracks on her face, I couldn't help but gently put
my arm around her shoulder and kiss her cheek. She didn't reject me. I kissed
her back, looking intently at her beautiful lips, unable to control my emotions, and pressed my lips to hers.
Her lips probably had some tears on them; they tasted a little salty. I held her lips in my mouth, my tongue
slowly darting out, tasting the tears on her lips. My sister's body trembled slightly, then she went
limp in my arms and closed her eyes.

I greedily sucked on her lips and slowly tried to slip my tongue into her mouth. At
first resisted a little, but slowly, her defenses crumbled, and she slightly opened her mouth. I immediately felt
a faint fragrance waft from her mouth, and my tongue took over her territory. I tentatively
explored , sometimes probing deeply, trying to embrace her tongue. Her breathing
became noticeably rapid, and gradually her tongue moved closer to mine, until our tongues slowly intertwined. What a
warm feeling! I greedily sucked on her sweet nectar, and she instinctively hugged me tighter.
My blood had already rushed to a certain point, and my penis was throbbing painfully. My hands began to caress her body uncontrollably
, slowly climbing to her breasts—so big and firm. My mouth continued to suckle
my sister, my hands stroking her breasts from bottom to top. Even through her shirt and bra, I could feel
her nipples, proudly erect. My sister's breathing became more rapid, her chest heaving, her legs
wriggling uncontrollably, her hands gripping my back tightly. I wrapped one hand around her back,
slowly sliding it down to her full, round buttocks. Her buttocks were pert and incredibly elastic; even
through two layers of pants, I could feel their slipperiness. My penis was rock hard, and reason was
gradually fading from my mind. My hand slid down her abdomen, slipping inside her panties, touching
her not-so-lush pubic hair. My sister suddenly snapped out of it and pushed me away forcefully. "Little handsome, we can't
do this , let go of me!"

My eyes were red. Seeing her push me away, I looked at her again, wanting to pounce on her once more. With a "smack
," my sister slapped me across the face. I froze for a moment before realizing what had happened,
then quickly turned and went into my room, locking the door. My sister had never hit me before,
not even in the years since Mom and Dad left.

"Xiao Shuai, listen to me. I didn't mean to hit you. I just wanted you to wake up. We're
siblings, we can't do this. Xiao Shuai, open the door, please let me explain." My sister thought I
was angry and comforted me from outside the door.

Hearing her voice outside, tears streamed down my face. Actually, I didn't blame my sister for hitting me
; I blamed myself for doing such a despicable thing to my sister. She's my sister, and she's so beautiful.
How could I defile her? Yet I kept trying to molest my sister. Last time, I even ejaculated on her
breasts , and I don't know if she even noticed. This time, I even reached out and touched her private parts. I've gone too far
.

"Little Shuai, open the door. At most, I'll agree to it because you're in puberty and
curious . As long as you don't go too far, I'll agree to it, okay, Little Shuai, open the door.
" My sister continued calling from outside the door when I didn't speak.

My sister was willing to sacrifice herself for me like this. I slapped myself a few times, opened the door, and
threw her arms. "Sis, I didn't mean to do this, but I couldn't control myself. Hit me, scold
me."

"Silly little brother, your sister is so willing to hit you and scold you. Does your face still hurt? Xiaoshuai, I know you like your sister
, and your sister likes you too, but we are siblings, we can't do anything too outrageous, you know? Your sister
knows Xiaoshuai has grown up and is curious about the opposite sex, and wants to have a girlfriend, right? You just
stole my first kiss, do you know that? You even dared to touch my breasts here, my breasts have never been touched by a stranger before
."

"Sister, you are so beautiful." I looked at my sister and answered her dreamily.

My sister looked at me, as if she had made a great decision, and said, "Sister knows you are curious about the opposite sex.
Sister promises you, you can find a girlfriend. If you really can't find one, as long as you don't go too
far with your sister, there are some things that sister can promise to do for you."

"Sis, I have a girlfriend." I said proudly to my sister.

The older sister's smile vanished instantly, then she smiled again and said, "Little brother, you have a girlfriend? When did
this happen? Did you two do anything?"

"Sis, it's that girl we met while hiking last time, her name is Liu Lili."

"Oh, that girl is quite pretty." The older sister said with a hint of jealousy, "Remember last time she
thought I was your girlfriend and was about to tell the teacher? How did she become your girlfriend?
What are you up to?"

"She just agreed to be my girlfriend today. Sis, do you want to know why she agreed to be my
girlfriend?"

"Yes, I want to know."

"Then you have to kiss me."
