From childhood to adulthood, my sister has been my "idol": not only is she beautiful and has a great figure, but she also excels academically
and is the student council president. Many people doubt that I'm her biological brother!
Because I'm not particularly good-looking, a stark contrast to my sister.

But God's creation of people is strange; my sister and I are indeed biological siblings.

My sister and I have always had a good relationship, though we're always bickering, it's true what they say: "Spare the
rod and spoil the child." I remember watching a TV series (I don't remember which
one , a foreign film, about a man and a woman. The man approached the woman and suddenly
reached his hand inside her skirt to grope her. After seeing this scene, we were both inexplicably excited.

That day, no one was home; our parents were at work. My sister suddenly said to me, "Brother, let's imitate the action from
TV ."

Hearing this, I was startled, but also somewhat interested in trying it. So I said to my sister, "Okay,
I'm coming."

My sister, mimicking the expression of women on TV, closed her eyes. I slipped my wicked hand inside. It was the first time I'd ever
touched a girl's underwear, and I was incredibly excited. But after a while, I got bored and pulled my hand
out . We started playing other games.

I thought that was the end of it, that we'd both grown up. I thought I'd slowly
forget about it, but fate had other plans: one summer when I was 12, I was in sixth
grade and my sister was in ninth grade. One day, my sister developed some red bumps, and she asked my mother to put some anti-itch
medicine on her back.

As my sister took off her shirt, I happened to enter the room, and that action was etched into my mind:
her breasts were just beginning to develop, not very big, but already "taking shape"—like small hills. The pink
nipples were like two tender little grapes atop those hills. My sister, like me, had very short body hair
and fair skin, making her body look like a piece of white silk, drawing my gaze.

At night, I tossed and turned, unable to sleep. Every time I closed my eyes, I seemed to see my sister naked again
.

I couldn't resist anymore and tentatively asked, "Sister, are you asleep?"

At that time, my parents thought I was still young and let my sister and I share a room. "I'm not asleep yet. Damn,
is something wrong?" My sister had just fallen asleep, of course she wasn't asleep.

"Nothing, I just wanted to ask you, do you remember when we were little? We played together so
happily." I decided to take it slow.

My sister didn't know it was a trap: "Of course I remember. Damn? A little boy reminiscing about his childhood?" She
still treated me like a child.

"Then do you remember the games we played when we were little?" I relentlessly lured her into my trap.

"There are so many, like throwing beanbags, hide-and-seek, hopscotch... there are so many. Which
one ?"

"I'm not talking about those, I'm talking about the ones we play together. Do you remember that time we were watching TV
and we imitated what happened on TV?" I was overjoyed to see she was about to fall into my trap.

My sister fell silent; I knew she was probably thinking back to that time.

I didn't want to waste any time, so I crawled out of bed, wearing only shorts, and went to my sister's bedside.

My sister saw me and quickly said, "It's so cold like that, come on, get under the covers." She then lifted one side of the blanket and
let me crawl under her.

Once under the covers, I knew my sister was aroused too, so I rolled over and straddled her.

My sister said shyly, "Tell me where you want to play."

But now that I was actually on top of her, I felt embarrassed and couldn't bring myself to say anything.

Seeing that I hadn't moved for a while, my sister said, "How about this, you can play wherever you want."

Hearing this, I was still shy and hesitated for a long time before finally mustering the courage
to say to her, "Lift up your clothes."

My sister lifted up her only undershirt, revealing her two mounds.
I stretched out my hands, grabbing one mound in each hand and starting to rub them.

Since I had never experienced anything like this before, and it felt amazing, I just kept rubbing like an idiot. My sister
must have felt great too; she kept her eyes closed, enjoying my rubbing of her breasts.

After a while, my sister started to get impatient. She glanced at my movements and said, "You...
you can't just rub...you can also use your mouth...eat..."

Actually, I had wanted to use my mouth for a long time, but I was afraid my sister would be unhappy and stop playing with me, so I had been holding back. Now
, encouraged like this, I was so happy!

I immediately opened my mouth and took one of my sister's breasts into my mouth. Although her breasts were quite large, they were still too big for a 12-year-old boy like me to fit completely in my mouth.

After taking her breast in my mouth, I felt incredibly good. The little nipple kept bouncing in my mouth,
stimulating my tongue; it's hard to describe the feeling.

I kept changing positions, trying to make it the best for both of us. We were both excited because it
was incest, and we both felt a sense of relief. But because I was still young, I naively thought that men and
women could have children just by kissing. So I didn't dare kiss my sister. I didn't know that there were many other things
involved in sex , but at that time, I thought that just being able to suckle my sister's breast was enough. I
didn't have any further thoughts (and wouldn't).

We played for quite a while, maybe half an hour. Later, I got bored and went back to my
bed to continue sleeping. My sister said to me, "If you want to play again, just say you're cold."

I hummed in agreement, and that's how my happy life began.

Since my sister and I started our intimate play, we've done this kind of play almost every day.
I usually initiate play after I've gone to bed, and she's very accommodating, always obliging—we're siblings!
Even during her period, it was no exception; after all, it wasn't actual penetration.

This relationship continued for over two years, and I started having more serious thoughts. But I didn't want to hurt
my dear sister.

Just when I was caught in this dilemma, the opportunity arose…

My sister had a classmate named Min, who lived upstairs from me (we attended a factory-affiliated school back then, and all the classmates were
children of factory workers; we knew almost everyone. My family lived on the second floor, and hers on the fourth). She and my sister were
very close, and she often came to my house to play. She didn't have any siblings, so she jokingly called me her little brother. She would often
come to my house to tease me.

"Hey, little brother, here's something fun for you. But you have to call me Sister Min!" Every time, I would obediently and
sweetly call her "Sister Min," and then she would tell me that she didn't actually have any, she was just teasing me! Then she
and my sister would laugh happily together.

I pretended to be clueless, but secretly thought, "Sister Min, don't you have anything for me to play with? I'll just
play then."

Oh, I forgot to introduce her: Sister Min is a little shorter than my sister and not as pretty.
But her figure is top-notch: although a bit chubby (or rather, voluptuous). Even in her first year of high school, she was already very "
eye-catching "—her breasts stood tall like two mountain peaks! Without the slightest tendency to sag.

That year, I was in my second year of junior high, and my sister was in her second year of high school.

As I grew older, my desire for girls with large breasts grew stronger, and in this respect, my sister's
small, delicate breasts could no longer satisfy me. Every time I saw Sister Min, I had an urge to sleep with her, but
I could never find the opportunity.

After having this thought, during another "intimate encounter" with my sister, I made this
request to her. I was fully expecting my sister to agree, but to my surprise, she flatly refused: "Brother, it's enough that you're playing with me,
why do you want to play with Min Gan?"

"Oh, sister, I just think that Min-jie is so close to you, it shouldn't be a problem to say something, right? Whether
she agrees or not is up to her, and besides, I promise I won't hurt her, just like when you play, is that not okay?"

My sister still insisted that she wouldn't. I had no choice but to say, "If it's not okay, then forget it, it was just a joke. Let's
play !" After saying that, I took my sister's nipple into my mouth and started sucking.

My sister then made a soft sound of pleasure. (We didn't dare to be loud because our parents lived next door.)

One day in mid-May, my parents went out because of something at the factory.

In the afternoon, Min-jie came to my sister: "Yan, my parents went out. I'm scared to sleep alone at home, can I
come down to sleep?"

My sister glanced at me, and I had to look away. I thought my sister would definitely refuse, because at
lunchtime I had made a promise with my sister to have a good time that night, how could I let someone else sleep at my house at a time like this?

To my surprise, my sister said, "Okay, I'm pretty bored tonight too, you can keep me company."

As soon as she left, I questioned her, "Sis, what's wrong with you? Didn't we agree to 'that' tonight
?"

She rolled her eyes at me, "You do this every day, aren't you tired of it? Just rest tonight, there will be plenty of
opportunities ."

Although I was extremely unwilling, I could only suppress these thoughts.

After dinner, while washing the dishes, I cursed my sister in my heart, "Why did you have to come now of all
times , ruining my good time!"

While watching TV, my sister arrived, "Oh, you guys are watching TV?!" with a big smile.

Seeing her, I knew I was destined to sleep alone tonight. I said listlessly, "Sis,
I'm going to read. Don't wake me, maybe I'll fall asleep while reading."

My sister smiled at me, a very mysterious smile.

Because of my bad mood, I didn't bother to guess the hidden meaning in her smile, and I turned and went into my room.
After reading for a while (how could I possibly concentrate?), I heard Min say to my sister, "Yan'er, our
water heater is broken. I want to take a shower at your place."

"What's with all that? Just shower if you want. Go to the bathroom first, I'll run the water for you."

A moment later, the sound of running water came from the bathroom.

I felt like I was sitting on pins and needles, constantly having the urge to "see the view," but I didn't dare do
anything .

Just then, I suddenly heard my sister say, "Brother, I have to go out for a bit. Watch the house. After
Min finishes her shower, turn off the stove for her. I'll be back in a little while, tell her not to leave." Then I heard
a "thump" as the door closed.

I pressed my ear to the door for a while, and after confirming that no one was there, I secretly slipped out and went to the bathroom door.
Our bathroom door is the kind that opens at the bottom. I squatted down and looked inside through the opening.

I saw Min completely naked, wiping her two peak-like breasts with a towel. Her breasts were large,
and her nipples were also large, unlike my sister's small cherries. Her hair was wet and disheveled. Looking further down, her
pubic area was dark, and her pubic hair was definitely more abundant than her sister's. Because of the hot water, her entire body was steaming
.

Since it was the first time I'd seen a girl other than my sister bathing, I was completely mesmerized. Plus, she was
rather plump, and I even had a strange feeling of "Yang Guifei emerging from her bath," and an urge to play with her.

But please note: at that time, my "playing" was limited to touching her breasts and sucking her nipples. I didn't know how to actually penetrate her!

After a while, afraid my sister would find out when she returned, I had to sneak back to my room.
When my sister finished bathing and asked me to turn off the stove, I glanced at her again: she was wearing my sister's bathrobe, but it couldn't hide her two breasts.
Her beautiful hair was draped over her shoulders, giving her a seductive air that made my mouth water.

Sister Min felt embarrassed by my stares: "Little brother, what are you looking at? Haven't you ever seen a beautiful woman before?"

I swallowed hard: "Sister Min, I only realized today how beautiful you are."

"Silly boy, didn't you know your sister Min was this beautiful before?" She was really shameless. After a while,
my sister came back, and the two of them huddled together again, whispering their girlish secrets. I went back to my
room , feeling a little sleepy, so I lay down and went to sleep.

I don't know how much time had passed when I was woken up by a series of urgent phone rings (every room in our house has a phone; my
father said it's convenient this way).

I groggily answered the phone. My sister's sweet voice came from the other end: "Come on over. Min said she wasn't used to it
and went back to her house to sleep."

I immediately perked up, and without even putting on my clothes, I rushed to my sister's room. Her room
was pitch black , without a single light.

I went to my sister's bedside and repeated our code: "Sister, I'm cold."

"Come on in," my sister's familiar voice came from beside me, just like before.

Hearing this, I knew she was ready, so I quickly slipped under the covers. Without saying a
word, as soon as I was under the covers, I reached out and grabbed my sister's breast. Hmm, something felt off: my sister's breasts should
n't be this big. Never mind, I lowered my head and sucked on my sister's nipple—even stranger, my sister's nipple
wasn't this big either.

At the same time, I realized something was amiss, and then I remembered the scent I smelled when I got into bed, which didn't quite match
my sister's usual fragrance. Just as I was wondering what was wrong, the light suddenly came on.

Ah... the person I was holding was my sister Min?!

My older sister was lying behind Min, smiling at me.

I was startled by the sight before me; I never expected that I was holding Min!
Instinctively I stopped what I was doing. But I forgot to pull my hand back, and it was still lingering on Min's ample breasts.

Min opened her tightly closed eyes, grabbed my hand, and guided it to her breasts, saying, "Little brother
, you feel so good touching me, don't stop!"

My sister chimed in, "Yeah, little brother, haven't you always wanted Min? How come you
're hesitant now that she's right in front of you?"

Hearing this, I got excited again: "Who said I'm hesitant? I'm just a little surprised."

I leaned down and said to Min, "Sister Min, do you really want to play with me?"

Min nodded shyly. Seeing this, I got even more excited, and my "little brother" rose up again
. I grabbed Min's breasts, which I had been dreaming of, and rubbed them vigorously. I lowered my head
and took the red "grape" of her large breast into my mouth, like a baby nursing.

Min, aroused by my teasing, began to moan softly.

We dared not be too loud, afraid the neighbors would hear.

I had dreamt of Min's breasts countless times, imagining many scenarios of suckling them,
and now it had become a reality: her large breasts were now clearly displayed before me,
the pink nipples glistening with my saliva, erect with excitement, seemingly beckoning me to possess
them, to ravage them with my hands.

Min then grabbed my penis and began to rub it with both hands. Under her rubbing, my
penis grew larger and larger.

I was excited because my sister and I had never done this before. We only ever rubbed each other's
breasts and touched each other's bodies. We had never tried anything this exciting.
After Min rubbed my penis for a while, I became extremely aroused. My penis became much larger than usual, even when I played
with , it had never been this big. Because I had never experienced anything like this before, I was at a loss.

I said to Min, "Sister Min, my penis is so swollen and uncomfortable. What should I do?"

Min then opened her previously closed eyes and stared straight at me, making me even a little embarrassed.
She parted her cherry lips and said, "Is this all you and Yan have ever done?" My sister nodded
ambiguously . Min sighed, "Sigh, what kind of play is this? This is how men and women should do things to
get pleasure. This is how my boyfriend and I do it."

As she spoke, she began to guide my penis with her hand. The pleasure traveled from her hand
to my penis, making me unable to stop.

As I savored the wonderful sensation from her hands, I continued to fondle her breasts, which she was so proud of.

Finally, she found the right spot, and I felt my glans enveloped in a warm, moist sensation. I asked Min, puzzled,
"Min, what is this? It feels so good."

"Don't...don't ask...you...you just need to thrust...thrust...you...you'll feel even more...
comfortable..." She was already in the mood. I listened to her and started thrusting. It hurt a little at first,
but the tight grip on my penis felt incredibly good, so good that I didn't want to stop. As I thrust,
I thought: I wish this moment could last forever.

With each thrust, Min began to moan: "Wow...you're so...amazing...I...my boyfriend
's...it's...as long as yours...it's so good..."

After a while, Min told me to pull out and bent down to lick her vulva. I was very obedient and
did as she said.

I sucked on the nectar from Min's vulva, feeling it was truly the finest thing in the world, delicious and not greasy at all.

At this moment, her vagina was overflowing with fluids: gushes of lustful water flowed freely, and I greedily
accepted it all with my mouth. (It's strange; I've never had this experience before, and I find my own actions
odd. Could it be as Confucius said: "Food and sex are human nature"—that sex is an innate human
instinct ?!)

As I was licking Min's honeyed vagina, I suddenly felt my penis being enveloped by something warm.
I stopped licking and looked down: it was my beautiful and pure older sister, holding
my penis in her cherry-like breasts?! Her movements were stiff, but she was working with great dedication.

Min saw it too and said, "Yan, what's wrong?"

"Seeing you two so comfortable, I'm getting excited too. Can I join you?" My sister raised her head,
looking at us with wide eyes, a strange light shining in them.

A threesome?! I had never imagined it. Although I often saw such scenes in those adult films, I
never thought it would actually be happening in front of me. I know that if I agree, they will definitely
gang up on me, and I'll be half-dead, if not dead.

Besides, Min-jie has had experience with this kind of thing with her boyfriend, so she's definitely not a virgin. As for my sister
... she's still a virgin. In the beginning, I only got together with my sister so I could touch her breasts. I can't afford to
let her virginity be ruined by me for my own pleasure. That responsibility is too great; I can't bear it.

My older sister seemed to sense my hesitation. She said softly, "It's alright, I'll just watch you two do it. I
won't ask you to actually have sex with me. Little brother, it's enough for you to touch me occasionally, that'll quench your thirst too."
After saying that, she stood up, took off her clothes, and then pulled my right hand to her left breast. So now
I was touching Min's breast with my left hand and my older sister's breast with my right—this comfortable feeling can't
be understood unless you experience it for yourself.

While touching her breasts, I secretly compared my older sister's breasts with Min's: my older sister's breasts
were smaller, but they felt great and were always firm; Min's breasts were much larger, but they
felt a little saggy. I think this might be because her boyfriend often touched them, and also because of gravity,
larger breasts have more mass!

"Haha..." While touching her breasts, my "little brother" was still running rampant inside Min's vagina,
ramming and thrusting . As I moved, Sister Min's body swayed with me. Her body looked especially beautiful:
her white flesh was like a snowball, and her two large breasts hung on it, swaying with her movements.

"I don't even need to play with her body, just looking at it is enough to make someone's nose bleed to death..." I thought.

I got up and made them kneel side by side on the bed. The buttocks of two big, round girls appeared in front of me,
seemingly beckoning my "invasion."

I couldn't help but drool. I went to Sister Min first and began to lick her private parts with my mouth.

Sister Min quickly let out a soul-stirring sound: "Ah...ah...so...so comfortable..."

Sister Min was not very happy: "Little brother, why are you only serving your own sister? What about your god
-sister ?"

I was afraid that if I offended her, I wouldn't be able to enjoy myself anymore, so I immediately moved my head to Sister Min's private parts again, but she said:
"No, I don't want this. Use your thing to insert it from behind."

I had no choice but to insert my "little brother" into Sister Min's honey cunt from behind. After penetration, I realized this position was
particularly good because it allowed for deep penetration; I felt I was completely inside Min-jie's deepest point. Min-jie
started moaning loudly, and my sister quickly covered her mouth with her hand: "Are you crazy?! Moaning so loudly!"

Min-jie smiled and said, "Sorry, I'm just too happy. Isn't it because your little brother's thing is so
amazing?" She then gave me a seductive look.

Seeing this, I stopped thrusting.

But Min-jie scolded me again: "I told you to be gentler, not to stop."

"Oh, I thought you didn't want me to move," I joked with her.

I started thrusting again, but cautiously, and Min-jie moaned softly. My sister also assisted
us, sometimes touching Min-jie's private parts, sometimes exploring my scrotum, and occasionally licking our
genitals. This experience was extremely pleasurable; I was practically going crazy with pleasure.

I felt the urge to ejaculate, and my thrusting quickened. Min-jie seemed to have reached her climax as well, her body undulating
faster . So I said to Min-jie, "I'm about to ejaculate, I'm going to come."

"No! Don't pull out. Just ejaculate inside. It's safe today." Min-jie shouted loudly when she heard me pull out my "
little brother ".

Hearing the words "it's safe today", I was a little surprised: "What do you mean?"

Min-jie saw my confusion: "Today is not my period."

Oh, so that's what it means! (But I still don't understand what a safe period is, and what is not
a safe period .)

So I let my "little brother" run rampant in Min-jie's vagina, and spurt after spurt of my semen
shot into the depths of Min-jie's flower core...

In the days that followed, whenever my parents were not home, Min-jie would come to stay with my sister overnight, ostensibly because
she was afraid my sister would be lonely and scared, but actually... hehe...

But this didn't last long. During the summer before Min-jie entered her senior year of high school, due to her parents' job
transfer, Min-jie went to study in Jiangsu. The night before she left, the three of us
spent the night in a hotel. That night was the most carefree, but also the "last supper." I
never saw . But undeniably, I still remember the passion I shared with her; after all, it was the most passionate and
enjoyable time I've ever had! I will always remember you, beautiful and sexy Sister Min!!

Yes, I also long for a sister like that. The poster is truly blessed! The poster has such a vivid imagination, I admire you! The poster is so talented! I support you continuing to post, expressing my firm support! I wish I had two sisters like that too, thank you for sharing! It's been a long time since I've seen such a good article. The poster is truly amazing; if I really had two sisters like that, I would be incredibly happy. I took a look and thought it was quite well written; it gave me a strong urge. I wish reality were like that. Wow, that's very realistic! You're quite the ladies' man, having your virginity taken.

But I wonder if you and your older sister actually slept together afterward? I don't know where you found this, but there should be more to it. Although the descriptions aren't extensive, it feels incredibly real.
