My older sister is already fully developed, and my penis is always rock hard.

My name is Shen Fei. I was born in a small county in central Shandong. My father is a high school teacher, and my mother works at the town's tax bureau. Our family isn't wealthy, but we're middle-class.

The story is about my

older sister and me. My sister's name is Shen Yan, and she's two years older than me. (I should mention that my sister and I are half-sisters, sharing the same mother but different fathers. I only recently learned this from my mother, which lessened my guilt somewhat.) Because we're close in age, we've always had a good relationship and are very close. I remember she always helped me bathe when I was little, until I started bathing myself in elementary school.

Besides my mother, she's the one who loves me the most in the world. I remember one winter when the wind was biting cold, and I cried from the cold. My sister took off her red scarf to warm my ears and then let me put my hands inside her cotton-padded coat to warm them. That was my first intimate contact with my sister, as I can remember.

But I was too young then to understand the concept of boys and girls; I just felt so lucky to have an older sister.

My first real urge to commit a crime stemmed from the impulses of adolescence. Back in eighth grade, I'd already been exposed to some erotic novels and Hong Kong Category III films, the most memorable being a movie called "Ghost Lady."

Of course, I watched all of this secretly at a classmate's house.

I dared not bring it home; if my father saw it, he'd beat me to death, because he was very strict with us.

Perhaps it was precisely his strictness that forged my sister's and my rebellious nature; this cannot be said to be unrelated to our family environment.

At that time, we lived in a teachers' dormitory building, one of the earlier families to move into an apartment building. Our home was on the sixth floor, not large, barely a three-bedroom apartment; actually, my sister's and my room were separated only by a wooden plank.

I remember the first time happened that summer. My parents went to work during the day, leaving just the two of us at home.

In the summer, we dressed rather revealingly at home; I often wore only a pair of shorts without underwear, and my sister usually wore shorts and a tank top.

Miss, a young woman, was seen kneeling and licking her vulva in a private room

during a nap. She was only wearing a small white panty at home, and you could occasionally glimpse her vulva (a fleshy little pussy, but it was fleeting and indistinct). This was what they called a wardrobe malfunction! But nobody paid any attention to it.

At that time, my older sister was already a high school sophomore. Her body had developed to a point where she was quite beautiful, if not fully mature.

In my eyes, she was prettier than any other girl I knew.

Once, I couldn't resist hugging her from behind and saying, "Sis, you're so beautiful, I want to marry you."

She shyly slapped my hand away, saying, "I don't want you, you're just clingy."

Often, she didn't treat me like a boy; perhaps in her eyes, I would always be that little boy who never grew up.

It was precisely this casualness and lack of guardedness, coupled with her naturally good figure and the allure of her beautiful buttocks during her nap, that aroused my inappropriate thoughts and triggered the primal instincts that had long been dormant during puberty.

That noon, it was just the two of us at home; my parents had gone to a relative's banquet and hadn't returned by noon.

After lunch, we lay in the living room watching TV, and when we got tired, we slept on the floor.

My older sister was sleeping on her side with her back to me, and my eyes were glued to her buttocks, as if I were bewitched, tempting me to devour them.

But I'm a coward, knowing that if I bit into them, she would fight me to the death.

Yet, seeing her little panties deeply embedded in her buttocks, her white buttocks as cute as peeled eggs, I finally couldn't resist the devil's temptation—I reached out to my own sister… My heart was pounding in my throat, my mind went blank, only thinking about what it would feel like to touch that white flesh.

I held my breath and gently placed my hand on her buttocks.

Whew! Thank goodness she didn't wake up, I reassured myself, and at the same time, I became bolder, and the bolder I became, the more excited I got, and the more excited I got, the bolder I became. The feeling of doing something naughty was incredibly exhilarating, even more so than my first time with my girlfriend.

My fingers slowly began to probe from the side edge of her underwear towards her buttocks, cautiously, pausing after each small indentation. My fingers first touched a few pubic hairs, then a soft, fleshy mound. Was this the legendary female vagina? It felt like a freshly steamed bun.

At this point, my body was almost pressed against my sister's.

I paused briefly to make sure she was still asleep, then took the opportunity to push my hand all the way in. As soon as my fingers slipped inside, I felt it was wet. This was the vaginal opening; that's where penetration would begin, right? I thought to myself, "It's so wet, my sister must not have wiped properly after using the toilet!" I gently stroked her vaginal opening a few times, but the more I touched, the wetter it became, the more slippery it felt. After a while, my sister's breathing became heavier, interspersed with a few soft moans. I felt she was awake, just keeping quiet to avoid embarrassment.

Suddenly, a daring idea struck me: why not seduce her? I boldly pulled down my underwear and pressed my already erect penis against her soft, white buttocks, while simultaneously digging my fingers into her untouched—no, untouched—little vagina.

Just as I confidently thought I'd won her over, she suddenly rolled over and pinched my hand hard, leaving a bloody welt. I cried out and immediately rolled to the side, grimacing and rubbing my hand, head down, not daring to look at her. She glared at me and said fiercely, "Next time you do that, see how I deal with you!" Knowing I was in the wrong, I made a face at her, chuckled twice, and hid in my room.

I avoided her for several days afterward. My mother noticed something was wrong and asked, "Xiaofei, what's wrong? Did you two fight again?" My sister looked aggrieved and said, "No way! Who would dare mess with your precious son? You can ask him yourself."

After she finished speaking, she nudged me with her lips and gave me a strange look.

For the next few days, I observed her closely

and saw nothing unusual. Knowing she hadn't told my parents, I finally felt relieved. Summer vacation was long, and my grades hadn't been very good. My dad made me stay home to study and wouldn't let me go out to play. My sister and I stayed home all day, either watching TV or sleeping. Although neither of us mentioned that day again, her unique allure remained.

After the first time, I started to miss that feeling, but it took a lot of effort to make my sister and me reconcile, so I didn't dare to do it again.

Until one afternoon, she was sleeping in the living room again. Looking at her white, round, perky little butt, the devil hidden in my heart suddenly sprang up and started to cause trouble.

I was unbearably hot, and my penis was rock hard and throbbing painfully.

Forgetting my sister's scolding and warnings, my mind was filled with her cute butt. Like I was possessed, I immediately took off my clothes and carefully lay down next to her.

After confirming she was truly asleep, I pressed my body against hers, my still-erect penis pressing directly against her buttocks. A wave of heat washed over me; the feeling was incredible.

My heart was pounding.

I slowly and gently rubbed against her, fantasizing about the real feeling of fucking.

Even now, thinking about it gives me that inexplicable urge.

Slowly, I sensed she might be waking up, so I quickly stopped, startled. After a while, seeing she didn't turn around or make a sound, I became bolder. I thought, "Last time she didn't like touching my pussy, so this time I'll try touching her breasts." I used my left hand to reach around her waist, finding the hem of her vest, and slowly moved my hand up her stomach. The first time I grasped her large breasts, I was a little nervous because my hands were trembling. I felt like a thief, secretly squeezing someone's treasure while the mistress was asleep.

That intertwining of sin and ethics, that entanglement of lust and morality, collided within my sister and me at that moment, creating an indescribable, distorted pleasure.

The instant I pinched her nipple, I clearly heard my sister let out a captivating moan—"Ah!" I knew she was awake. Her eyes were tightly closed, and she remained silent, pretending nothing had happened, which emboldened me, as if I had received her tacit approval.

I became incredibly excited; wouldn't it be even more thrilling to simply pull down her panties and be naked together?

But just as I was pulling her panties down, my sister suddenly sat up, pushed my hand away, her face flushed. She didn't hit me, didn't scold me, and wasn't angry; she just said, "Stop it, go watch TV."

Then she went into the bathroom.

Suddenly, her words chilled me to the bone. The little flame of desire that had just ignited was so easily extinguished by her. It felt like falling from a peak to a trough—so painful! Although the first two attempts ended in failure, it was precisely these failures that led to the beginning of our incestuous relationship.

After those first two attempts, I gradually grew bolder. Whenever no one was home, or when my older sister wasn't looking, I would sneakily touch her, either her buttocks or her large breasts.

She usually didn't say anything, at most pinching me in retaliation when I wasn't paying attention.

I knew she didn't dislike what I did, so later I often tried to touch her breasts and her vulva when it was just the two of us at home, constantly teasing her.

At first, she resisted somewhat, but her way of refusing was to plead with me in a coquettish voice, "Good brother, stop it, go to sleep."

Or she would push my hand away and continue pretending to be asleep, ignoring me. I knew she must feel very comfortable when I touched her, because when I touched her vulva, there was slippery fluid flowing out.

This gradually progressed until later. Even when she wasn't sleeping, but sitting next to me watching TV or reading, my hand would unconsciously reach out and touch her. If she felt something, I could even slip my hand inside her clothes, but only touch, nothing more.

However, one time I got really into it, so I simply wrapped my arms around her waist and pinned her down, reaching inside her panties and stimulating her vulva. She held me tightly with her eyes closed, seemingly enjoying it. I took the opportunity to pull down her entire panty, but she immediately covered herself with her hand, saying, "Don't look!" Why? Women can be so funny sometimes. After touching me several times, what secrets could she possibly have?

There's no reason why, but you're not allowed to look! My older sister was adamant, and I couldn't persuade her otherwise. Fine, I'd not look. I wisely covered our lower bodies with a towel.

Later on, we started having some simple kisses, but it felt strange, not quite good, lacking the feeling of a couple.

When I got excited, I would rub my hard penis against her pussy, but I didn't dare to penetrate her.

At that time, I didn't feel any guilt or shame.

I just thought it was fun, and I was afraid to go in because I was worried about getting pregnant and ruining our relationship.

Looking back, it was so childish. So, we would always just rub it against her buttocks or her mons pubis, all under a blanket. My sister never let me see her pussy. Back

then, I felt like I ejaculated very easily; I'd ejaculate after only a few strokes. Sometimes it was on her lower abdomen, sometimes on her buttocks, and once it landed on my sister's hand. That time, she suddenly got aroused and wanted to masturbate me. Maybe it was the first time someone was controlling me, and I got too excited and ejaculated all over her hand.

We always carefully controlled our boundaries, never penetrating.

The only time we crossed that line was in the winter of her senior year of high school. Summer was usually our peak season; winter wasn't as convenient, but sometimes we couldn't resist.

Back then, I especially longed for my parents to go to sleep every night. As soon as they were sound asleep, I would sneak into my sister's room. It felt like having an affair.

I would slip into her bed and hug her from behind, starting to stimulate her vulva. I knew she wasn't asleep, but she was too proud to show it.

But I was getting her so excited that she couldn't take it anymore. She spread her legs and pulled my penis into her vagina, moaning and begging me to put it in.

I don't know if it was from nervousness or excitement, but I ejaculated as soon as I touched the entrance. I was so excited that I ejaculated all over her vulva, and some semen dripped onto her sheets. I thought, "Oh no, if Mom finds out, we're doomed." But that wasn't the worst part. At that time, we didn't know how to get pregnant. We thought that would also fertilize a woman's genitals. This made us both nervous for a whole month until she got her period, and then we were finally at ease. But after that, we never had any intimacy again.

3...

Later, my older sister graduated from high school and got into Zhejiang University, going to Hangzhou.

I had three girlfriends and slept with four women during my three years of high school, one of whom was my teacher and the other was my classmate's mother.

Of course, this glorious achievement was accompanied by my failure to pass the college entrance examination.

This time, I didn't listen to my mother and go back to retake the exam; instead, I resolutely chose to join the army.

Coincidentally, I was transferred to the Nanjing Military Region, only a two-hour drive from my sister's city.

Several years passed in a flash, and we broke off that relationship. Perhaps as we grew older, we both realized it was a mistake, so neither of us brought it up again.

However, this didn't affect my sibling-like relationship with my sister. Whether at home or on the phone or QQ, we were still as close as ever, only the topics of conversation changed from "us" to "you."

We were like inseparable best friends, naturally discussing our love lives and commenting on each other's boyfriends and girlfriends. When I told her I had changed girlfriends again, she actually defended my ex-girlfriends and complained jealously, "You've had so many boyfriends, how come I haven't had a single one!" Actually, she's never lacked suitors. From elementary school onwards, the love letters she received could fill an entire room, but none of those playboys caught her eye. It

wasn't until the end of her freshman year of college that she announced she'd finally ended her 19-year single life.

That means her virginity was definitely taken by her boyfriend.

She told me this guy wasn't a student at the school, and was considerably older than her.

I said, "Shen Yan, you've gone bad, you've fallen so low as to become a gold digger!"

Go to hell! Does a younger brother talk to his older sister like that? I like him for who he is, not his money.

Who would believe that? He looks like he's 30, right? He's not that old, he'll only be 25 after his birthday next month.

That's still much older than you. Are you two excited together? Whether you're excited or not is none of your business! Little brat, mind your own business...

Actually, I wasn't the only one who didn't approve of their relationship; both their parents did too. My parents felt they didn't know much about the guy and were afraid my sister would be deceived and taken advantage of.

Her parents looked down on our family, disliking my sister for coming from a small town and feeling we weren't a good match.

But my sister was always proud and a bit willful, ignoring her family's objections and moving in with her Prince Charming the following year.

During my military service, I visited her rented place on a weekend; it was a very grand house, fully equipped with all sorts of household items.

No wonder she loved that kind of life.

However, our happiness was short-lived. At the end of our senior year, she was preparing to graduate, while I was preparing for my major.

When I visited her over the weekend, she excitedly told me she was planning to marry her boyfriend right after graduation. I laughed and said, "Aren't you in a hurry? Are you afraid you won't get married?"

She replied, "No, I'm just afraid if I marry him a few years later, your brother-in-law will be a little old man! What if I don't want to get married then?" Just two days later, I received a call from her. She had broken up with her boyfriend, and she cried the whole time on the phone! I had never seen her so heartbroken. During

that time, my sister was completely devastated. She didn't plan to go home for the New Year, and she stayed in her room all day, never going out. Everywhere I went, there were cigarette butts and empty bottles.

I happened to have a month-long leave to visit my family, but I didn't go home. Instead, I stayed to be with her and take care of her.

People in the family often say that joining the army is a regret for three years, but not joining is a regret for a lifetime. I feel I've matured a lot in the past few years in the army; at least I'm no longer the ignorant little kid I used to be.

We spent the New Year together. I made dumplings for her, washed her face and hair, and did her laundry, just like taking care of a child.

On the second day of the Lunar New Year, some of her local classmates invited her out for a gathering. I thought it was good for her to get away and clear her head, so I agreed on her behalf.

After dinner that evening, she wanted to go back to her little dark room to face the wall.

I stopped her, saying, "You smell terrible! Are you going to see your classmates like this tomorrow? This is fine!" She was still listless and had no energy at all.

I didn't want to spoil her, so I grabbed her hand and dragged her into the bathroom, saying, "If you don't want to shower, I'll shower you."

Seeing that she couldn't resist me, she reluctantly agreed to take a shower.

But not long after she went in, I heard her scream inside.

I thought something had happened, so I went in and found that the water heater wasn't on, and she was soaked in cold water. She stood there shivering, both ashamed and angry, wiping the water from her face while complaining that I was doing it on purpose.

At this moment, her perfect figure was completely exposed to me. Her breasts, which I had touched before, were fuller than before, and her buttocks were rounder and perkier than before. Her legs were pressed tightly together, and I could only see a small tuft of dark hair on her pubic area.

While I was still in a daze, my sister got a little annoyed. "Stop looking! Get me a towel!" Only then did I react. I took the towel and draped it over her shoulders, then carried her back to the bedroom.

She kept her head down, avoiding my gaze. I pretended nothing had happened, boiled some water, and told her to take a shower. Seeing her wrapped in the towel, a sinful urge surged up again.

Lust once more began to override my reason; after all, it had been over a year since I'd been with a woman.

That night, my sister slept next to me. I couldn't fall asleep, thinking about childhood memories, about her familiar yet strange body beckoning me. My penis, which had been erect for so long, became wickedly hard again.

The next day's gathering was large, with men and women filling a table. My sister had deliberately dressed up before leaving, changing her clothes several times.

I said, "It's a class reunion, not a blind date. Why are you doing this?" My sister rolled her eyes at me, ignoring me. After getting ready, she said quietly, "It is a blind date, after all!" That night, she insisted I go with her, saying she wanted to introduce me to some nice girls.

When we arrived, she didn't introduce me to anyone, not even my identity as her younger brother. She just held my hand tightly, never letting go, as if afraid I'd run away. Her intention was clear: I was just a scapegoat boyfriend. But if it made her happy, I was willing to sacrifice something, especially since it was my own sister.

That night, she drank a lot, and I couldn't stop her. She also got me quite a bit drunk. By the time we got home, it was past midnight, and I was dizzy.

But seeing that long-lost smile on her face, I suddenly felt that all that indulgence didn't matter anymore. I just wondered how much bitterness was hidden in that smile.

When we got home, she slurred, "I'm fine, I was just pretending to be drunk. Look how well I can pretend!" Then she started spinning around in circles for me, acting like a drunkard. I've seen plenty of drunken women, but my sister is the only one who can be so adorable when drunk and acting crazy.

Finally, she nestled peacefully in my arms, giving me a seductive, affectionate look before quietly closing her eyes. Seeing her blissful expression, a feeling of happiness welled up from somewhere unknown.

I think she must have seen another world at that moment, a world without worries and sorrows, where she could see whoever she wanted, do whatever she wanted, stare out the window all day, or sleep soundly until dawn…

When I carried her into the bedroom, she was already fast asleep. I hesitated for a moment before helping her take off her outer clothes, thinking it would be more comfortable to sleep naked.

But seeing her wearing sexy pink lingerie, I felt a little excited.

She was more feminine than before.

Her buttocks were noticeably rounder, and her panties were thin lace, making her vulva appear fuller and outlining the shape of her cunt.

My heart was pounding, and I really wanted to touch her. That guilty impulse that had been buried deep in my heart for so long suddenly returned.

My hand slowly approached her, and I could already feel the warmth emanating from her body. But just as I was about to touch her, I pulled the blanket over her body and fled the bedroom.

I think I must have drunk too much; it was the alcohol that was acting up.

How could I have such wicked thoughts about my own sister? I'm all grown up now, not that ignorant child anymore.

I kept telling myself to stop, but the desire within me was something I couldn't suppress.

I rushed into the bathroom to take a shower and cool myself down. Halfway through taking off my clothes, I was suddenly drawn to a pair of white panties. My sister had deliberately changed out of them before we went out that night; they were unwashed and left on top of a pile of clean clothes, with a yellowish stain in the middle.

Suddenly, as if possessed, I picked them up and held them to my nose, inhaling deeply. Yes, that was the smell—the scent only female animals emit, a scent that could drive any male wild.

The feeling was like my body was on fire, a frenzy about to explode.

My mind was filled with images of women's beautiful naked bodies, full breasts, round buttocks, warm, moist vaginas. Just as I was about to explode, I wrapped the panties around my erect penis, ejaculating all my thick semen onto them, the scents of male and female mingling together.

5…

The next day, I slept until after ten o'clock. When I got up, my sister asked me mysteriously, "What naughty thing did you do last night?" I was still half asleep when I woke up, and without thinking much, I tried to deny it. "No, I just took off your outer clothes. Is that a bad thing?" I said half-jokingly. "

I'm not talking about that. I mean... last night in the bathroom..." My sister stammered, sounding shy and embarrassed. But as soon as she mentioned the bathroom, I immediately understood. After I finished last night, my legs were so weak, and I hadn't washed my underwear before going to bed.

Her reminder made me realize I was in trouble. I'd been found out! I was so ashamed I wanted to disappear.

My sister noticed my embarrassment and, perhaps trying to comfort me and ease the tension, said not to do that again, as it's bad for your health.

Then she walked away shyly.

We didn't speak to each other all day. I was so ashamed, feeling like I had no face left in front of her. It would have been better to have raped her last night.

Thinking about this, I suddenly realized that she must have been very aroused after breaking up for so long, otherwise her underwear wouldn't have had such a strong smell.

Why not seduce her? Maybe she'd like to, after all, we had that kind of relationship when we were kids.

I thought about it, but when it came to actually doing it, I didn't know where to start. That evening, we squeezed together to watch TV, both of us distracted. After a while, my sister got up first, saying, "This is boring, I'm going to sleep now. You should go to sleep early too."

After she left, I randomly changed channels,

but my mind had already followed her into the bedroom. About half an hour later, I got up and quietly went to her door. The door wasn't locked. I quietly opened it a crack, and inside, my sister was sleeping on her side. The light was dim, and I guessed she wasn't asleep either. I struggled internally—should I go in? What if she refused? How would I face her then? After all, we weren't little kids anymore… Just as I was agonizing over this, my sister suddenly turned over. I clearly saw that her eyes were open and she was looking directly at the door.

The moment our eyes met, I was so scared that I quickly retreated to the sofa.

Oh no, I've been found out! My heart was pounding with guilt and nervousness.

What should I do? How can I explain?! I closed my eyes in frustration. What flashed through my mind wasn't my sister's reproachful look, but her full breasts, round buttocks, and plump vulva. I

figured I might as well go all in; she'd already noticed anyway.

I made up my mind and went in. Outside, I took off my clothes, leaving only my boxer shorts. I turned off the TV, but the living room light was on, letting in light through the half-open bedroom door. This way, I could see my sister's body clearly, and the light wasn't too bright.

I gently lay down beside her, struggling internally before finally reaching out and gently placing my hand on her waist. She didn't react. It felt like everything was back.

It felt like we were back in our childhood, like that first summer

when we lay together like this. Reliving those unforgettable moments with my sister again, even though we were no longer children and had both had those experiences,

we still couldn't help but feel excited and nervous. It wasn't just the unspeakable taboo involved, but also the thrill of breaking that taboo.

Realizing this, I hugged my sister tightly, my hands beginning to explore her body.

When my hand reached her genitals, I could already feel her wetness through her thin panties.

I gently lifted her blanket and pressed my body tightly against hers. My already erect penis was right at her crotch. My hand wasn't satisfied with just rubbing through her pajamas; I adjusted it and slipped it inside her panties. I could feel her heart pounding. She must be exhausted from pretending to be still while I was exploring her for so long. Just as I was about to intensify my movements to see her reaction, she suddenly rolled over and hugged me tightly! It's back, it's really all back now! Those forbidden feelings are back! We rolled around together, panting heavily. Everything was so crazy. Every nerve in my body was throbbing with excitement. I wanted to fuck her, I wanted to fuck her pussy. This time, I was determined to truly enter her body and fulfill my long-held desire.

Removing our last obstacle, I slowly thrust my hips downwards, my large penis pressing against my sister's fleshy vulva. She guided my penis with her hand, gently guiding it to the entrance of her vagina, a warm and soft enveloping sensation as it sank in.

Slowly, my penis parted her vaginal opening, the tightness, warmth, and moisture inside transmitting to me through the glans, allowing me to truly experience what it felt like to fuck her.

I leaned down, pressing my entire body against hers, and in the most traditional position, slowly thrust my hips.

Beneath me, my sister seemed to have returned to the shyness of our first encounter with forbidden fruit; her legs were only slightly apart, not wrapped around my waist, her arms were around me, her eyes were closed, her face was slightly flushed, her breathing gradually became rapid, and her mouth seemed to want to open.

I eagerly kissed my sister's mouth, inserting my tongue into her mouth, our tongues intertwining, and my sister's panting finally became more relaxed, turning from soft gasps into moans.

It felt like a long-lost sensation. My sister's vagina was unusually wet; I hadn't seen a girl like this in a long time. I could feel the fluid flowing, not just the wetness. With each thrust, there was a soft, wet sound as my penis passed through her.

My sister's arms tightened around me, her chest heaved more and more, her moans grew more intense, and her hips arched upwards in response. I knew she was close to orgasm. I quickly increased the force of my thrusts, each one more powerful than the last. With a cry of "Ah!" from my sister, I felt a gush of hot fluid spurt from her vagina, followed by her body arching tightly. She had orgasmed.

After only a slight pause, I thrust again with ferocious force, biting her nipples like a mad dog. She kept her eyes tightly shut, unable to look, but her moans had turned into screams. Everything was so familiar yet so strange. The frenzy lasted only a few minutes before I quickly ejaculated inside her, holding it tightly without pulling out.

We didn't speak for a long time, just held each other until my penis went soft and slid out of her vagina, letting the obscene fluids flow from her little hole and onto the sheets... It felt a little wicked, a little satisfying, and a little inexplicably guilty.

Later, she removed my hand, got out of bed, and went to the bathroom to wash up. I lazily lay on the bed, wondering how to talk to her later. My sister came in and said, "Why don't you go sleep over there?" I didn't insist and went to my room.

6...

The next day, neither of us mentioned what happened last night, acting as if nothing had occurred.

During the day, she still asked me to go out with her friends and eat. In the evening, we went to a karaoke bar. She drank a lot, whining and clinging to the microphone, singing terribly, not caring if her classmates laughed at her.

When I saw it was getting late, I tried to coax her home, but she started acting drunk, saying she wanted to play a little longer. I felt really awkward, since several of her classmates were there. Seeing their surprised looks, I was at a loss for what to do.

However, I didn't dare delay any longer and forcefully dragged her out of the private room.

I was afraid she might do something shocking again, which would be really bad, especially since we had just broken that taboo last night.

After we got home, she was still blaming me for dragging her out, playfully hitting and punching me, begging me to leave her alone, never to care about her again.

Later, I felt that my sister might really be drunk and mistaking me for that person, and I felt inexplicably sad.

But I didn't have the mind to argue with her, and I was about to boil some water for her to wash up and sober up.

But as soon as I turned around, she suddenly hugged me tightly from behind, crying and saying, "Don't go, please, don't go, I can't live without you!" That "you" could never refer to me. In that instant, I suddenly realized that I was just an emotional filler for her loneliness. Even after

so long since the breakup, she still couldn't forget that person, and a wave of jealousy welled up in my heart. Perhaps what she truly wanted was something I could never give her.

I turned around and hugged her tightly, trying to give her the tenderness that the other man could.

My sister, like a little woman, cried tears of emotion in my arms. I hesitated for a moment, then scooped her up by her knees and lifted her horizontally in my arms.

Just like in a romantic drama, I carried her into the bedroom. She let me hold her softly, as happy as a bride.

After last night, I thought things would naturally progress, but it wasn't until I pressed her down on the bed that she seemed to come to her senses and began to resist.

Crying, she said, "We can't do this! I'm your sister, we can't do this!"

I was startled by her actions and stood there, unsure what to do.

But seeing that I didn't move, she suddenly became a different person, wrapping her arms around my neck and whispering affectionately in my ear, "I love you..." and so on...

After entangled with her for a long time, I felt a burning desire, my penis was hard, and I genuinely wanted to fuck her. So, I stopped caring whether she was acting or not and started taking off her clothes...

before she snapped out of it. I

first tore off her outer garment, then her sweater and stockings... After a few moments, she started acting crazy again, hitting me, crying and begging me to stop... "Good brother, we can't do this! You brat, if you do this again, I'll go home and tell Mom!" But her resistance seemed so fake; perhaps only in this way could she derive psychological pleasure? This time, I didn't stop; instead, I decided to play along and finish the act.

I ignored her words, focusing only on taking off her clothes, stripping her naked first.

I took off her sweater, pushed up her bra, and a pair of soft, white breasts popped out. I grabbed one breast with one hand and sucked on her other nipple. Her crying stopped abruptly. "No, no!" she cried, pushing my head away forcefully. Because I was holding onto her nipple, her entire breast was stretched and deformed. She cried out in pain, probably from the force, and pulled her hand back.

I took the opportunity to pull off her stockings, but she reacted quickly, grabbing them tightly and kicking her legs restlessly.

I had to struggle to turn her over, first pinning her hands behind her back... then grabbing the waistband of her stockings and panties and pulling them down together.

Her round, white buttocks were finally exposed. She was still softly begging me to let her go, but her behavior made it seem more like she was begging for pleasure. After all that, she was basically exhausted. I let her go, took off my pants, spread her legs, and rubbed my large penis against her vulva. I knew it was already wet and sticky.

At this point, she stopped fussing and opened her mouth as if to bite. How could I not let her have her way? I lowered my head and kissed her little mouth. As my tongue swirled inside her mouth, her fists, which had been pounding on me, suddenly stopped, and I began to caress my body… Finally, her hands reached behind me and wrapped around my neck! Her cries turned into rapid breathing… By this time, her lower body was already wet like a swamp. I adjusted the angle slightly and inserted my large penis.

A warm sensation enveloped my glans, instantly feeling a sense of sexual bliss.

With another thrust, I pushed forward, inserting my entire penis to the root.

My sister involuntarily wrapped her arms around my waist, letting out a muffled groan from her nose. Her vagina contracted sharply, tightly gripping my penis head. It felt incredibly good; I had no idea vaginas could bite! After penetrating, I held her buttocks, letting her thighs rest on my arms, and thrust in and out forcefully, all the way to the bottom each time, at a fast pace. I kept asking her if it felt good. She kept her eyes closed and didn't speak, only making sounds I'd never heard before.

Soon, her moans grew louder, "Ah, ah..." and I felt my penis struggling more and more inside her vagina, it was incredibly tight, and I was showing signs of wanting to ejaculate.

It felt like something was sucking me in; after a few thrusts, I couldn't control myself anymore. I could only hold her tightly, letting my penis release all the semen from my scrotum inside her. After I finished, my sister let out a scream and collapsed onto the bed, motionless. I ejaculated

, and she orgasmed too.

After that night, every night I would turn off the lights, sneak over, climb into her bed, and have sex with her. My sister didn't object anymore, and we did it every night for those days. However, she never allowed me to stay overnight in her room; she'd kick me out as soon as we were done—truly heartless after getting rid of me, haha.

But I didn't really care. She had sexual needs too; we each got what we wanted. After all, after that initial burst of sexual urge, we both felt a little regretful, though her guilt was probably stronger than mine.

I didn't really care. Back then, although I had a girlfriend back home, our relationship was just so-so; we barely talked on the phone once a week,

and it felt like it was about to break down. Although I'd crossed that line with my sister, things were different now. After so many years, we'd both had relationships and plenty of sexual experience. Even though it was sometimes exciting and thrilling, I always felt something was missing. Many times when I tried to kiss her genitals, she firmly refused, let alone give me oral sex. A few times, she even seemed averse to kissing me. Perhaps in her heart, I was just a sex toy…

I soothed her body but not her heart.

My month-long leave passed quickly, and I returned to my unit. Her reluctance to see me go was somewhat comforting. She told me not to overthink things, that she'd be fine.

A few months later, I suddenly heard that she'd gotten back together with her ex-boyfriend.

I knew they were living together again. Although I felt a little unhappy, I knew my chances were slim.

Several times I called to say I wanted to visit her, but she politely declined, saying I should go back and spend more time with Xiaoyan (my girlfriend at the time), and that I had my brother-in-law to take care of me, so I didn't need to worry.

She never mentioned what happened between us, as if none of it had ever occurred.

Autumn arrived in the blink of an eye, and I chose to recover and returned to my hometown in Shandong.

This distanced us further, and because she consistently avoided the topic, I felt awkward bringing it up again; after all, we were adults, and I felt some guilt and remorse.

Gradually, we seemed to have truly forgotten about it all. Now my sister is getting married soon, and my relationship with Xiaoyan is back on track. Let those unpleasant memories be buried where the sun doesn't shine…
