Mysterious relationship with my sister

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

But God is strange in creating people, and my sister and I really are siblings.

My sister and I have always had a good relationship, even though we're always bickering. It's a perfect example of "spare the rod and spoil the child." I remember watching a TV series (I don't remember which one) when I was little, 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. Seeing this scene, we were inexplicably a little excited.

That day, no one was home; both my parents were at work. My sister suddenly said to me, "Brother, let's imitate the moves we see on TV."

I was startled, but also somewhat tempted to try. So I said to my sister, "Okay, I'm coming."

My sister imitated the expressions of the women on TV and closed her eyes. I reached 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, and we both grew up. I thought I would gradually forget about it, but fate had other plans: in the summer of my 12th year, when I was in sixth grade and my sister was in ninth grade... One day, my older sister developed some red bumps on her body, and she asked Mom to put some anti-itch medicine on her back.

I happened to enter the room just as my sister took off her shirt, and that image immediately stuck in my mind: her breasts were just beginning to develop, not very big, but already "taking shape"—like small hills. Her pink nipples looked like two tender little grapes atop those hills. Like me, my sister had very short body hair and fair skin, making her body look like a piece of white silk, drawing my gaze.

That 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 any longer, so I tentatively asked, "Sister, are you asleep?"

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

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

My sister didn't know it was my trick: "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 persisted, leading her step by step into my trap.

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

"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 we saw on TV?" I was overjoyed to see that 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 a pair of shorts, and went to my sister's bedside.

As soon as she saw me, she said, "It's so cold like this, come on, get under the covers." She then lifted one side of the blanket, letting me crawl under it.

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

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

But once I was actually on top of her, I felt too embarrassed to speak.

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

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

My sister lifted up her only piece of clothing, a small tank top, and those two bun-shaped things reappeared in front of me. I stretched out my hands, grabbing one of her breasts with each hand and starting to rub them.

Because I had never had such an experience before, and it felt especially good, I just kept rubbing like an idiot. My sister must have felt great too; she kept her eyes closed, enjoying me rubbing her breasts.

As time went on, my sister started to get impatient. She glanced at my actions 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 that my sister would be unhappy and stop playing with me, so I had to hold back. Now, encouraged like this, I was so happy, you can't even describe it.

I immediately opened my mouth and took one of my sister's breasts into my mouth. Although my sister's breasts were still developing and not very big, for a 12-year-old boy like me, it was still too big for my mouth to completely cover.

After I took my sister's breast into my mouth, I felt particularly comfortable. The little nipple kept jumping in my mouth, stimulating my tongue. It's really hard to describe the feeling at that moment.

I kept changing positions, trying to make the feeling best for both my sister and myself. We were both excited because it was incest, and we both felt a sense of liberation. But at that time, because I was still young, I naively thought that men and women could have children just by kissing. So I didn't dare to kiss my sister. I didn't know that there were many other things involved in sex between men and women, but at that time, I thought that being able to suckle my sister's breasts was already very satisfying. I didn't have any further thoughts (nor would I).

We played for 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 in the future, just say you're cold."

I said "Mmm," and that's how my happy life began.

Since my sister and I had our first physical intimacy, we've been playing like this almost every day. Basically, I was the one who initiated going to play with my sister after I went to sleep, and she was quite accommodating, always obliging—we're siblings, after all! Even during her period, it was no exception; it wasn't like we were actually penetrating each other.

This relationship continued for over two years, and then I had thoughts of taking things further. But I didn't want to hurt my dear sister.

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

My sister had a classmate named Min, who lived upstairs from us (we attended a factory-affiliated school at the time, and all the classmates were children of factory workers, so we knew almost everyone. We lived on the second floor, and she lived on the fourth). Min and my sister were very close, and she often came to our house to play. Since she didn't have any siblings, she jokingly called me her little brother. She often came to our 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," only then would she tell me that she didn't actually have anything and was just teasing me! Then she and my sister would laugh happily together.

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

Oh right, 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 you could say voluptuous). Even in her first year of high school, she was already very "eye-catching"—her chest curves stood tall like two mountain peaks! There wasn't the slightest tendency to sag.

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

As I get older, my desire for girls with large breasts grows stronger, and my older sister's small, delicate breasts can no longer satisfy me in this regard. Every time I see my sister Min, I have an urge to sleep with her, but I can never find the opportunity.

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

"Oh, sister, I just think that Min-gan and you are so close, 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 allowed?"

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 again!" 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 came to my sister's house: "Yan, my parents are 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 she would definitely refuse because we had made plans to have fun together that night at lunch. How could I let someone else sleep at my house at a time like this?

But to my surprise, she said, "Okay, I'm pretty bored tonight too. It'll be good for you to keep me company."

As soon as Min left, I questioned my sister: "Sis, what's wrong with you? Didn't we agree to do 'that' tonight?"

My sister 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 later."

Although I was extremely unwilling, I could only suppress the thought in my mind.

After dinner, as I washed the dishes, I mentally cursed my sister Min: "Why did you have to come now of all times? You ruined my plans!"

While I was watching TV, Min arrived: "Oh, you're watching TV?!" she said with a big smile.

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

My sister looked at me and smiled, a very mysterious smile.

Because I was in a 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 her older sister, "Yan'er, the water heater at my house is broken. I want to take a shower at your place."

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

A moment later, I heard the sound of running water coming from the bathroom.

I felt like I was sitting on pins and needles, with an urge to "take a look," but I was too afraid of my sister to do anything.

Just then, I suddenly heard my older 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 sneaked out and went to the bathroom door. My bathroom door is the kind that opens at the bottom. I squatted down and peered inside.

I saw my older sister, Min, completely naked, drying her large, round breasts with a towel. Her breasts were large, and her nipples were large too, unlike my sister's small cherries. Her hair was wet and disheveled. Looking further down, I could see her pubic area was dark, and she definitely had more pubic hair than my sister. Because of the hot water, her 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 actually penetrate her!

After watching for a while, I was afraid my sister would find out when she came back, so I sneaked back to my room. When my sister finished showering 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 hair was draped over her shoulders, giving her a charming and alluring look that made my mouth water.

My sister was embarrassed by my gaze: "Little brother, what are you looking at? Haven't you ever seen a beautiful woman before?"

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

"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, felt a little sleepy, and lay down to sleep.

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

I groggily answered the phone. My sister's sweet voice came from the other end: "Come on over. Min said she's not 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 reached my sister's bedside and repeated our code: "Sister, I'm cold."

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

Hearing this, I knew she was ready, so I quickly slipped under the covers. Without another word, as soon as I was under the covers, I reached out and grabbed my sister's breast. Hmm, something felt strange: my sister's breasts shouldn't be this big. "Whatever," I thought, and lowered my head to suckle my sister's nipple again—even stranger, her nipples weren't this big.

While feeling puzzled, I realized something was amiss. I remembered the scent I'd smelled when we got into bed; it 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 Min-jie?!

My sister was lying behind Min, smiling at me.

I was startled by the sight before me. I never imagined I was holding Min-jie! Instinctively, I stopped what I was doing. But I forgot to pull my hand back; it was still resting on Min-jie'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!"

She 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, my energy returned: "Who says 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 became even more enthusiastic, and my "little brother" rose high again. I grabbed Min's breasts, the ones I'd always dreamed of, and rubbed them vigorously. I lowered my head and took the red "grapes" of her nipples into my mouth, like a child nursing.

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

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

I had dreamt of Min's breasts countless times, imagining all sorts of scenarios of suckling them. I never imagined it would become a reality: her magnificent 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 rubbing 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 bigger than usual, even when I played with my sister, 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, which made me even a little embarrassed. She parted her cherry lips slightly and said, "Is this all you and Yan have ever done?" Her sister nodded ambiguously beside her. Min sighed, "Sigh, what kind of play is that? That's how men and women should act to achieve pleasure. My boyfriend and I do it this way."

As she spoke, she began to guide "me" to her vulva with her hand. Pleasure traveled from her hand to my penis, making me unable to stop.

While enjoying the wonderful sensation from her hand, I continued to play with her breasts, which she was so proud of.

Finally, she found the right spot, and I felt my glans being enveloped in a warm, cozy sensation. I asked Min, "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 aroused. 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 my thrusting, Min started moaning, "Wow...you're so...amazing...I...my boyfriend's...it's as...long as yours...it's good..."

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

I sucked on the honey-like fluid from Min's pussy, feeling that it was truly the finest delicacy, delicious and not greasy.

At this moment, her pussy was also "overflowing": wave after wave of lustful fluid flowed freely, and I greedily accepted it all with my mouth. (It's strange, I've never had such an experience before, and I find my own behavior strange. Could it be as Confucius said: "Food and sex are human nature"—that sex is a natural human instinct?!)

As I was licking Min's pussy, I suddenly felt my "penis" being enveloped by something warm again. I stopped licking and looked down: it was actually my beautiful and holy sister, who was holding my "penis" in her cherry-like mouth?! Her movements were stiff, but she was working very hard like a professional.

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

"Seeing you guys enjoying yourselves so much, I'm getting excited too. Can I join you?" My older sister looked up, her big eyes gleaming with a strange light.

A threesome?! I'd never imagined it. Although I'd often seen scenes like this in movies, I'd never thought it would actually be happening in front of me. I knew that if I agreed, they would gang up on me, and I'd be half-dead, if not dead.

Besides, Min had experience with her boyfriend, so she was definitely not a virgin. My sister… she was still a virgin. Initially, I only got together with her so I could touch her breasts. I couldn't let her virginity be destroyed in my hands for my own pleasure. The responsibility was too great; I couldn'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. Just touch me occasionally, little brother, that'll quench your thirst." With that, she stood up, took off her clothes, and then pulled my right hand to her left breast. Now I was touching Min's breast with my left hand and my older sister's breast with my right—the feeling of comfort is something you can't understand unless you experience it for yourself.

While touching them, I secretly compared my older sister's breasts to Min's: my older sister's breasts were smaller, but felt wonderful and remained firm; Min's breasts were much larger, but seemed to sag slightly. I think this might be because her boyfriend often touched them, and also because of gravity—larger breasts have more mass!

"Haha..." While I was fondling her breasts, my "little brother" was still wreaking havoc inside Min's vagina, thrusting and ramming wildly. With my movements, Min's body swayed along with me. Her body looked especially beautiful when it swayed: her white flesh was like a snowball, with two large breasts hanging on it and swaying.

"I don't even need to play with her body, just looking at it can make someone bleed from their nose and die..." I thought.

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

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

My sister quickly let out a seductive sound: "Ah...ah...so...so comfortable..."

My sister Min wasn't happy: "Little brother, why are you only serving your own sister? What about your god-sister?"

Afraid of offending her and then not getting any pleasure, I immediately moved my head towards my sister Min's private parts. She said, "No, I don't want that. Use your thing to insert it from behind."

I had no choice but to insert my "little brother" into my sister Min's honeyed vagina from behind. After inserting it, I realized this position was particularly good because I could insert it very deeply. I felt I had completely entered the deepest part of my sister Min. Sister Min started moaning loudly, and my sister quickly covered her mouth with her hand: "Are you crazy?! Moaning so loudly!"

Sister Min smiled and said, "Sorry, I'm just too happy. Isn't it because your brother's thing is too powerful?" After saying that, she gave me a flirtatious look.

Seeing this, I stopped thrusting.

Who knew that Sister Min would lecture 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 carefully, and Sister Min also moaned softly. My sister was also helping us, sometimes touching Sister Min's private parts, sometimes exploring my scrotum, and occasionally licking our genitals. This experience was extremely pleasurable, I was simply going crazy with pleasure.

I felt the urge to ejaculate, and my thrusting quickened. Min-jie seemed to have reached her climax too; her body was moving 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 as soon as she heard me pull out my penis.

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

Min-jie noticed my confusion: "Today isn't my period."

Oh, I see! (But to this day, I still don't understand what a safe period is, and what isn't.)

So I let my "little brother" run rampant inside Min-jie's vagina, shooting wave after wave of my semen deep into her flower core...

In the days that followed, whenever my parents weren't home, Min-jie would come to keep my sister company 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 transfers, 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 haven't seen Min-jie since that day. But undeniably, I still can't forget 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 Min-jie!

[The End]

From childhood to adulthood, my older sister has always been my "idol": not only is she beautiful and has a great figure, but she also has excellent grades and is the student council president at school. 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 like that; my sister and I really are siblings.

My sister and I have always had a good relationship, even though we're always bickering. It's true what they say: "Spare the rod and spoil the child." I remember watching a TV series when I was little (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. Seeing this scene inexplicably excited us.

It just so happened that no one was home that day; our parents were at work. My sister suddenly said to me, "Brother, let's imitate the moves on TV."

Hearing this, I was startled, but also somewhat eager to try. So I said to my sister, "Okay, I'm coming."

My sister imitated the woman's expression on TV and closed her eyes. I reached my wicked hand inside. Touching a girl's underwear for the first time, I was incredibly excited. But after a while, I got bored and took my hand out, and we started playing other games.

I thought that was the end of it, and we both grew up. I thought I would gradually forget about it, but fate had a cruel joke on me: That summer when I was 12, I was in sixth grade, and my sister was in ninth grade. One day, my older sister developed some red bumps on her body, and she asked Mom to put some anti-itch medicine on her back.

That 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 any longer, so I tentatively asked, "Sister, are you asleep?"

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

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

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

Actually, I had wanted to use my mouth for a long time, but I was afraid that my sister would be unhappy and stop playing with me, so I had to hold back. Now, encouraged like this, I was so happy, you can't even describe it.

"Oh, sister, I just think that Min-gan and you are so close, 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 allowed?"

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 again!" 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 came to my sister's house: "Yan, my parents are 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 she would definitely refuse because we had made plans to have fun together that night at lunch. How could I let someone else sleep at my house at a time like this?

But to my surprise, she said, "Okay, I'm pretty bored tonight too. It'll be good for you to keep me company."

As soon as Min left, I questioned my sister: "Sis, what's wrong with you? Didn't we agree to do 'that' tonight?"

My sister 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 later."

Although I was extremely unwilling, I could only suppress the thought in my mind.

After dinner, as I washed the dishes, I mentally cursed my sister Min: "Why did you have to come now of all times? You ruined my plans!"

While I was watching TV, Min arrived: "Oh, you're watching TV?!" she said with a big smile.

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

My sister looked at me and smiled, a very mysterious smile.

Because I was in a 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 her older sister, "Yan'er, the water heater at my house is broken. I want to take a shower at your place."

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

A moment later, I heard the sound of running water coming from the bathroom.

I felt like I was sitting on pins and needles, with an urge to "take a look," but I was too afraid of my sister to do anything.

Just then, I suddenly heard my older 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 sneaked out and went to the bathroom door. My bathroom door is the kind that opens at the bottom. I squatted down and peered inside.

I saw my older sister, Min, completely naked, drying her large, round breasts with a towel. Her breasts were large, and her nipples were large too, unlike my sister's small cherries. Her hair was wet and disheveled. Looking further down, I could see her pubic area was dark, and she definitely had more pubic hair than my sister. Because of the hot water, her 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 actually penetrate her!

After watching for a while, I was afraid my sister would find out when she came back, so I sneaked back to my room. When my sister finished showering 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 hair was draped over her shoulders, giving her a charming and alluring look that made my mouth water.

My sister was embarrassed by my gaze: "Little brother, what are you looking at? Haven't you ever seen a beautiful woman before?"

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

"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, felt a little sleepy, and lay down to sleep.

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

I groggily answered the phone. My sister's sweet voice came from the other end: "Come on over. Min said she's not 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 reached my sister's bedside and repeated our code: "Sister, I'm cold."

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

Hearing this, I knew she was ready, so I quickly slipped under the covers. Without another word, as soon as I was under the covers, I reached out and grabbed my sister's breast. Hmm, something felt strange: my sister's breasts shouldn't be this big. "Whatever," I thought, and lowered my head to suckle my sister's nipple again—even stranger, her nipples weren't this big.

While feeling puzzled, I realized something was amiss. I remembered the scent I'd smelled when we got into bed; it 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 Min-jie?!

My sister was lying behind Min, smiling at me.

I was startled by the sight before me. I never imagined I was holding Min-jie! Instinctively, I stopped what I was doing. But I forgot to pull my hand back; it was still resting on Min-jie'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!"

She 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, my energy returned: "Who says 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 became even more enthusiastic, and my "little brother" rose high again. I grabbed Min's breasts, the ones I'd always dreamed of, and rubbed them vigorously. I lowered my head and took the red "grapes" of her nipples into my mouth, like a child nursing.

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

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

I had dreamt of Min's breasts countless times, imagining all sorts of scenarios of suckling them. I never imagined it would become a reality: her magnificent 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 rubbing 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 bigger than usual, even when I played with my sister, 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, which made me even a little embarrassed. She parted her cherry lips slightly and said, "Is this all you and Yan have ever done?" Her sister nodded ambiguously beside her. Min sighed, "Sigh, what kind of play is that? That's how men and women should act to achieve pleasure. My boyfriend and I do it this way."

As she spoke, she began to guide "me" to her vulva with her hand. Pleasure traveled from her hand to my penis, making me unable to stop.

While enjoying the wonderful sensation from her hand, I continued to play with her breasts, which she was so proud of.

Finally, she found the right spot, and I felt my glans being enveloped in a warm, cozy sensation. I asked Min, "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 aroused. 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 my thrusting, Min started moaning, "Wow...you're so...amazing...I...my boyfriend's...it's as...long as yours...it's good..."

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

I sucked on the honey-like fluid from Min's pussy, feeling that it was truly the finest delicacy, delicious and not greasy.

At this moment, her pussy was also "overflowing": wave after wave of lustful fluid flowed freely, and I greedily accepted it all with my mouth. (It's strange, I've never had such an experience before, and I find my own behavior strange. Could it be as Confucius said: "Food and sex are human nature"—that sex is a natural human instinct?!)

As I was licking Min's pussy, I suddenly felt my "penis" being enveloped by something warm again. I stopped licking and looked down: it was actually my beautiful and holy sister, who was holding my "penis" in her cherry-like mouth?! Her movements were stiff, but she was working very hard like a professional.

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

"Seeing you guys enjoying yourselves so much, I'm getting excited too. Can I join you?" My older sister looked up, her big eyes gleaming with a strange light.

A threesome?! I'd never imagined it. Although I'd often seen scenes like this in movies, I'd never thought it would actually be happening in front of me. I knew that if I agreed, they would gang up on me, and I'd be half-dead, if not dead.

Besides, Min had experience with her boyfriend, so she was definitely not a virgin. My sister… she was still a virgin. Initially, I only got together with her so I could touch her breasts. I couldn't let her virginity be destroyed in my hands for my own pleasure. The responsibility was too great; I couldn'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. Just touch me occasionally, little brother, that'll quench your thirst." With that, she stood up, took off her clothes, and then pulled my right hand to her left breast. Now I was touching Min's breast with my left hand and my older sister's breast with my right—the feeling of comfort is something you can't understand unless you experience it for yourself.

While touching them, I secretly compared my older sister's breasts to Min's: my older sister's breasts were smaller, but felt wonderful and remained firm; Min's breasts were much larger, but seemed to sag slightly. I think this might be because her boyfriend often touched them, and also because of gravity—larger breasts have more mass!

"Haha..." While I was fondling her breasts, my "little brother" was still wreaking havoc inside Min's vagina, thrusting and ramming wildly. With my movements, Min's body swayed along with me. Her body looked especially beautiful when it swayed: her white flesh was like a snowball, with two large breasts hanging on it and swaying.

"I don't even need to play with her body, just looking at it can make someone bleed from their nose and die..." I thought.

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

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

My sister quickly let out a seductive sound: "Ah...ah...so...so comfortable..."

My sister Min wasn't happy: "Little brother, why are you only serving your own sister? What about your god-sister?"

Afraid of offending her and then not getting any pleasure, I immediately moved my head towards my sister Min's private parts. She said, "No, I don't want that. Use your thing to insert it from behind."

I had no choice but to insert my "little brother" into my sister Min's honeyed vagina from behind. After inserting it, I realized this position was particularly good because I could insert it very deeply. I felt I had completely entered the deepest part of my sister Min. Sister Min started moaning loudly, and my sister quickly covered her mouth with her hand: "Are you crazy?! Moaning so loudly!"

Sister Min smiled and said, "Sorry, I'm just too happy. Isn't it because your brother's thing is too powerful?" After saying that, she gave me a flirtatious look.

Seeing this, I stopped thrusting.

Who knew that Sister Min would lecture 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 carefully, and Sister Min also moaned softly. My sister was also helping us, sometimes touching Sister Min's private parts, sometimes exploring my scrotum, and occasionally licking our genitals. This experience was extremely pleasurable, I was simply going crazy with pleasure.

I felt the urge to ejaculate, and my thrusting quickened. Min-jie seemed to have reached her climax too; her body was moving 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 as soon as she heard me pull out my penis.

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

Min-jie noticed my confusion: "Today isn't my period."

Oh, I see! (But to this day, I still don't understand what a safe period is, and what isn't.)

So I let my "little brother" run rampant inside Min-jie's vagina, shooting wave after wave of my semen deep into her flower core...

In the days that followed, whenever my parents weren't home, Min-jie would come to keep my sister company 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 transfers, 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 haven't seen Min-jie since that day. But undeniably, I still can't forget 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 Min-jie!
