My Sister is a Slut

Chapter 1

Summer vacation has begun.

For a long time now, I won't have to brave the sweltering heat to go to school every day, nor will I have to worry about staying up late watching porn online and

being late the next day. It feels like a heavy burden has been lifted, and I feel completely relaxed. Unexpectedly, Dad has ordered us not to go out this

summer without a valid reason. The reason is that my sister and I will be facing the college entrance exam next year. I don't know exactly what the situation is, but my parents and the parents of my classmates are all on edge, nervously

anticipating a major crisis. 　　Although my parents are very good at making money, neither of them is highly educated. They used to run a business, and now they own a clothing factory in town . Their biggest wish right now is for my sister and me to get into university. They can't help us with our studies, so they can only focus all their energy on disciplining us. Therefore, my sister and I are confined to the house, trying our best not to be distracted from our studies. To balance work and rest and avoid damaging our brains, the housework is also divided between us , but this is paid work, and we can get paid. They emphasized that my brother and I should help each other, make progress together, and supervise each other; there would be a reward for reporting any violations. 　　It felt so good to wake up naturally. When I woke up, the sun was high in the sky. Mom and Dad had already gone to the factory. After washing my face and eating the breakfast they left for me, I watched TV. Around 10:30, my sister finally came downstairs . Then she plopped down on the sofa next to me, hugged one leg, rested her chin on her knee, and stared blankly at the TV screen, looking like she hadn't woken up properly. 　　Lately, when I'm close to her, I feel like a certain scent emanating from her is wafting into . I can't quite put my finger on what it is, but now I think it's a woman's scent. I can even be inexplicably certain that the scent is coming from her cleavage or crotch. This thought makes my heart race and my breathing heavy, so the scent seems even more pronounced. A lewd thought instantly took over my mind, and I couldn't shake it off. 　　My sister and I are actually twins, but we look surprisingly alike. In terms of appearance, it seems my sister has taken all my good features. I'm 1.65 meters tall with an average face; I'd definitely go unnoticed in a crowd . 　　My sister is a head taller than me, with a smooth, fair, oval face, almost flawless. Her high nose and full lips exude a wildness within their refinement. Her eyes aren't large, but they complement her face perfectly, making her incredibly lively and alluring. These days, there are so many busty 90s girls online showing off their V-shaped faces, all with excessively large eyes, which I find disgusting. My parents are decent-looking, but judging solely by their appearance, I wonder if I was adopted. 　　She was still lazily staring at the TV, her arms now crossed over her chest, her arms pressing down on a noticeable bulge. Her bare feet were on the edge of the sofa, her legs bent in an M-shape and spread out to the sides. Underneath the soft fabric of her pajama bottoms, the curves of her buttocks and thighs were clearly visible, and the shape of the fleshy mound between her legs was even faintly discernible. My sister has a great figure. The subcutaneous fat accumulated during puberty in the last two years has made her originally slender figure fuller and more curvaceous. My best friend He Wei once said to me sourly, "My sister must be frequently 'pleased' by men, otherwise how could a young girl have such a mature and alluring figure?" 　　I chased after He Wei and gave him a good beating. But he wasn't the only one I'd heard this from. Several years ago, when we were in the same junior high school, I heard rumors about my sister dating boys. She didn't get into the town's high school, so my father paid to send her to a private high school in the county. We weren't in the same school anymore, but I still heard gossip time to time. 　　Thinking about it, an image suddenly flashed into my mind: my sister's snow-white, voluptuous body being brutally fucked by another boy . My sister twisted her body, spread her legs, and moaned as … Although I'm still a virgin, because I watch a lot of porn, my brain has a fairly rich collection of such images. My penis involuntarily became engorged and erect, and at the same time, a sharp, aching pain welled up inside me. A crystal-clear thought surfaced—I want to fuck my sister. 　　Although I wondered if I was going crazy, my mind a turmoil of emotions, this thought remained unwavering and clear. I was serious; I really wanted to do it! 　　In the past, when I masturbated after watching porn, the images of my sister, even my mother, would appear . But after ejaculating, I would feel guilty for a long time, and then I would have to justify myself for another long time before I could forgive myself. But this time, it wasn't just a fantasy; I really wanted to have sex with my sister. To insert my swollen, rock- hard penis into my beautiful sister's cunt. 　　Suppressing the urge to immediately push my sister onto the sofa and force myself on her, I thought it was best . 　　Compared to my sister, I was more confident in my intelligence. I had always been a good student, something my parents were very satisfied with, and they often boasted about it in front of others. Perhaps there was no other suitable space for me to showcase my abilities at school , so I could only bury myself in my studies. Fortunately, my brain is pretty good at handling these things; problems that are difficult for others are easy for me to solve. I don't always get first place, simply because I don't want to. In other words, to put it bluntly, if I wanted to be number one, no one else would get it. 　　When I graduated from junior high, I chose the only high school in town. Several of my close friends were there, and I didn't like boarding school far from home, so I didn't go to a better school. The high school curriculum didn't put much pressure on me either . 　　My dad's stay-at-home order didn't affect me much either; even if I left home, I didn't know what to do. Most of my friends are similar to me in temperament, and I had planned to spend the holiday reading, surfing the internet, and sleeping. However, I know my sister doesn't think that way. She makes many phone calls every day, and sometimes she even goes to her room to listen in. Yesterday, a boy called and asked her to meet him outside the door. Maybe my sister doesn't like him, so she asked me to go out and tell her she wasn't home. 　　Seeing her so listless, she must really dislike being cooped up at home all the time. 　　"Sister, how about I give you a suggestion?" Although I really wanted to plan it out properly, I couldn't help I was actually incredibly nervous inside, and I had to work hard to keep my voice from trembling.

She glanced at me, frowned, then looked back at the TV screen. "What is it?"

she asked listlessly.

"Sister, I've realized I'm practically unpopular with girls. I feel like none of the girls in my class pay any attention to me. I

really want to know what it's like to have a girlfriend."

"You? I think you should stick to your studies." Her expression suggested she wasn't planning to continue the conversation.

"My suggestion is this," I turned and sat cross-legged on the sofa, facing her. "Do you want to go out?

You don't want to stay home with me all summer, do you? -- But because of homework and chores,

Mom and Dad want me to keep an eye on you. So you can't go out, right? Actually, you really want to go out."

"Hmm? Are you trying to trick me into revealing something? And then betray me?"

My mind raced, but it was like an engine running idle, completely inefficient. It kept repeating the same question:

"What should I say? What should I say?"... I could only take it one step at a time. In any case, I couldn't be

the coward she used to think I was. I had to be thick-skinned and ruthless.

So, mustering my courage, I said, "What I mean is, how about I help you with chores and homework?

On the condition that you become my girlfriend. Of course, you still get the wages Mom and Dad give you, how about that? You see, you don't

lose anything, it's a win-win situation."

"You're interested in playing house?" She turned to look at me, somewhat puzzled.

After a while, she realized what I meant and angrily scolded me, "What do you mean? Are you trying to

take advantage of me? Are you out of your mind?! You're my brother, you want me to date you? Have sex with you? Shut up and

get out of here. Think about what you're doing! You're crazy, I have to tell Mom and Dad, you'll be in big trouble.

From now on, you'll have to do all the chores yourself!"

I forced a calm smile, but my mind was actually blank. I regretted my madness after being rejected.

But since it was already done, there was no turning back, I had to grit my teeth and continue. My older sister isn't stupid,

she seemed to understand that I wanted to sleep with her, saving me the trouble of beating around the bush. More importantly, she didn't go crazy with shock. I

should still have room to argue.

"You want to tell Mom and Dad? Where's the evidence? I'll deny it to the death. They don't believe I would do that.

Don't forget, I'm a model student!" My reputation is indeed good; I have no blemishes at school,

and recently I received praise for volunteering at a mental hospital. Our town is a semi-rural area,

with several factories, a detention center, and a mental hospital. Many people's first

reaction to mental hospitals is danger. Actually, I think they're quite normal, just talkative and acting strangely, but I didn't find them aggressive

. I did the volunteering mainly out of curiosity; I didn't expect the school praise to be so exaggerated.

"But don't forget, Mom and Dad know you can lie; they've seen through you more than once."

Hearing her tone soften, I needed to further de-escalate the conflict.

"That was years ago! I was still young then."

"Tch," my sister rolled her eyes at me and said nothing more. She wasn't going to argue with me about this anymore.

The atmosphere became a bit tense, and I couldn't think of anything new to say. After a while, I couldn't

resist trying again. I felt like a pathetic, shameless wretch, but the desire in my heart seemed to be growing

stronger .

"Sis, can you reconsider? There's so much work, and so much homework. You know what I'm thinking,

let me do it once, okay? I think about it every day, but I've never had the chance to touch a girl... Besides, my penis is small,

I won't last long... You don't have to waste your time, and I can do all the work for you, and then

... you can go on a date." Never having done it with a woman before, and not being able to last a few seconds was all bullshit to

my sister .

"I don't date boys."

"I mean, you and girls..."

My sister looked at me like I was an idiot, then turned to look at the clock on the wall and said, "Time to go

work in the yard." Then she got up from the sofa and went upstairs. I stared at her back, and found the way she swayed her hips as she

walked incredibly sexy. Her two pert buttocks bounced merrily with the rhythm of her steps. Having broken through my own

inner taboos, my gaze, now unrestrained, roamed freely over my sister's body, unwilling to miss

any opportunity.

When my sister came downstairs, she had changed into athletic capri pants and a t-shirt, her hair casually tied back. The dark

, tight pants accentuated the snow-white skin of her exposed calves.

The alluring curves of her thighs and buttocks, covered by fabric, made my penis erect again.

Our yard was spacious, a plot of land my father had specially bought and built from the edge of the village, three times the size of an average

family . A cement path led to the house in the middle, with a vegetable garden on the left and a

pond on the right. The pond's inner walls were tiled to serve as a swimming pool, but no one had time to maintain it, and it was filled with

rainwater and grime. The vegetable garden was laden with tomatoes, cucumbers, and beans. These past few days, we'd been picking a basket of

vegetables every day, far more than we could eat ourselves, so my father took them to the factory canteen every morning to cook for the workers.

Luckily , we were both on holiday, otherwise all this stuff would have rotted in the yard.

My sister was picking tomatoes with a bamboo basket, and every time she bent over, her round buttocks would stick up high, the

outline clearly visible through them. I followed behind, greedily staring at her buttocks and the bulging mound between her legs,

completely mesmerized. The sun overhead was scorching. Soon, my sister's exposed skin was sunburned, and her face

was covered in fine beads of sweat. When she got up to wipe her sweat, she noticed my embarrassing behavior.

"What are you doing following me!"

"I think you're about to get sunburned, you should consider my suggestion. But sister,

it's okay if you don't agree today. Any day is fine, I'll wait!"

"Forget about it!" Although the walls around the yard were high, and our detached house didn't have any

neighbors next door, my sister still lowered her voice guiltily. I couldn't think of any good ideas for the time being, so I stubbornly

helped her with the work. When she bent over, I would change angles and stare at her breasts and buttocks to take advantage of her.

After a while, feeling I couldn't take it anymore, I decided to relieve myself manually, otherwise my penis might burst.

I turned and ran to the bathroom, closing the door. As soon as my pants came down, my swollen, purplish-red penis sprang out with a snap.

It wasn't the small one I'd described to my sister; it was thick and hot. Holding it in my hand, I could feel it

throbbing with each beat of my heart. Just

as I was about to stroke it, my eyes caught sight of the laundry basket next to the washing machine, piled high with clothes to be washed.

Suddenly a thought struck me: if there were any of my sister's panties in there, they would definitely smell of her cunt! I

frantically pounced on the basket and started rummaging through it. And there it was, a pair of black panties with delicate lace trim. But judging by

the size, it must have been my mother's. My heart pounded with excitement, and my hands trembled as I pulled open the crotch, right next to her cunt, and

found some yellowish stains. Touching them with my fingers, they weren't completely dry, like semi-dried paste. I held it

to my nose and inhaled deeply, impatiently. It was a pungent, foul smell, but it wasn't just the smell of urine; it contained

a scent that made my blood boil and was irresistible.

I was so excited I almost screamed, inhaling the air with all my might. Then I crumpled the fabric into a ball

and held it to my nose, inhaling deeply. This reduced the pungent smell, replacing it with a rich, strong feminine scent.

It was hard to describe, but equally exciting. I alternately unfolded and crumpled the fabric, savoring the different scents,

while simultaneously stroking my penis rapidly with my hand. The pleasure intensified, and just as I was about to climax, I pulled the underwear

over my penis and began stroking it back and forth.

The soft fabric provided a completely different sensation to my penis compared to my hand, and the psychological stimulation was unparalleled.

Although I wanted to prolong this pleasure, a sudden, intense wave of ecstasy, like being struck by lightning,

almost made me faint. My hot penis convulsed repeatedly, and thick streams of semen gushed out.

I lost count of how many times I shuddered. When I came to my senses, I found the underwear in my hand smeared with sticky semen, with drops

dripping from between my fingers onto the floor… Exhausted but satisfied, I cleaned up the mess…

My sister hadn't told my parents about this, for which I was incredibly grateful. The next few days were

filled with endless chores and being bombarded with homework questions by Dad. My sister seemed to be growing increasingly impatient. I stole

two pairs of underwear from her bedroom; with them, the time didn't feel so unbearable. My intentions were clear,

so being caught stealing underwear wasn't anything shameful or a big deal. Meanwhile, I kept an eye out for

opportunities , ready to intensify my offensive and seize the moment.

"If you can't accept me right away, we can... take it slow."

"I really misjudged you before, thinking you were a pushover."

"Hehe, not at all, just a wolf in sheep's clothing. So, what's your thought?"

"Would I do something so despicable just because you do some chores for me?"

"Not at all despicable, I've been wanting to do it for ages! Just consider it helping me, okay? And you're not

losing like doing it?"

"It's not that I don't like it, it's disgusting!"

"How about just kissing?"

"Just thinking about it is disgusting, kissing you is even more disgusting, stop bothering me..."

"I swear you don't have to worry about anything. If you fulfill my wish, I'll do whatever you say from now on.

I'll never make you unhappy, and I'll never blackmail you..."

...

"Even just letting me hug you is fine..."

...

Washing dishes, doing laundry, cleaning the bedroom, living room, kitchen, and yard—many chores were much more tiring and incredibly

dirty . And my sister hadn't made any progress in her daily practice when Dad checked. I felt my sister wasn't a very principled person, but I

believed she would take my advice to heart more and more.

It was time to clean the garbage pit in the yard. The pit, several cubic meters in size, was built with bricks and cement.

Garbage was usually stored there temporarily, and then pushed to the centralized garbage disposal

area . The pit, which had been overflowing for days, was emitting a pungent odor. To

prevent flies, a lot of poison had been sprayed. Dead flies covered the surface. My sister frowned deeply,

covering her nose and mouth with her hands. Seeing this, I deliberately used a fork to vigorously stir up the things on the ground. Spoiled

leftovers, rotten vegetable leaves, watermelon rinds, toilet paper… many other things were indistinguishable, and as I stirred,

the stench immediately filled the air.

My sister tried to run away, but I stopped her.

"You do it yourself…"

"Deal?" I smiled wickedly.

Her face turned bright red, and after a long pause, she finally said, "I can only hug."

"Then, you have to keep your word. Also, you can't resist if I touch your butt

." Since my sister had given up on her shame, I wanted to press my advantage. "It's just touching your butt, it won't do anything." I said, reaching for her

butt .

"...Go do your work first." My sister turned away.

"No problem, don't worry, I'll only touch your butt. If I touch you anywhere else, you can punish me by not touching you for a day."

"Okay... okay. I'm going back to my room, you go take a shower after you finish your work!" I almost laughed out loud. Did she

not understand what I meant or was she pretending not to?

"Wait a minute!" My sister was stunned, looking at me with a complicated expression, indicating that she didn't know what I wanted to do. I met

her gaze and looked at her steadily, then said, "Pinky promise."

My sister naturally extended her index finger and hooked it with mine, then we pressed our thumbs together and pushed back and forth a few

times. A warmth suddenly rose from the bottom of my heart, and memories surfaced. My sister and I grew up together. Although we didn't have any

telepathy or anything like that, we were the people who shared the most secrets with each other. When we're hiding something from adults

or fighting against other kids, pinky swearing is a ritual to declare our close relationship.

It took almost an hour to finish, and after a quick tidy-up, I went to take a shower. I

washed myself twice with soap, making sure there were no dead spots, to avoid leaving any lingering smell of trash. My penis remained erect, painfully so.

Downstairs, I found my sister sitting on the sofa, her posture a bit stiff and awkward. She must be very nervous.

I really wanted to go over and hug her. But I was also feeling guilty, so I changed my mind.

So I ordered her, "Take off your pants and lie down on the sofa."

Three black lines instantly appeared on her face: "I think you promised you could touch my butt, but you didn't say you had to take off your pants

..."

"But I said touch my butt, not touch my pants." My tone left no room for argument. If she objected now,

how could I continue?

At my insistence, my sister finally bent down and pulled down her pants, leaving only her light blue underwear. Her smooth,

white thighs immediately aroused me. My penis squeezed the underwear hard, as if trying to break free of its restraints. I

slowly walked over, my sister with her back to me, her arms crossed over her chest, forgetting my command to lie down on the sofa. I stroked her

two round, firm buttocks, feeling the pleasure in my hands for the first time. My sister's body trembled, as if she had just

realized it, and she moved to lie down on the sofa, burying her head and pressing her legs tightly together, her buttocks

hardening from the effort.

"Since you're going to be touched anyway, why don't you relax and enjoy it, sister?" I tried to comfort her. Despite my restraint,

my voice was still off-key.

I squatted down, my face very close to my sister's buttocks. I couldn't let her resist, so I kept

my promise , gently stroking my sister's buttocks with both hands, sometimes lightly grasping and kneading, the snow-white flesh

changing shape under the pressure of my palms. My sister's breathing became heavy and irregular. I tentatively moved my face closer,

letting my breath fall on her buttocks, secretly

inhaling . Finally, I couldn't resist licking her, my salivary glands seemingly overstimulated, forcing me to swallow hard.

My sister felt my kisses and licks, letting out a frustrated, ambiguous cry, but she didn't

react. So my lips and tongue became bolder, roaming up and down her fleshy buttocks,

leaving wet patches. Occasionally, they would glide across her thighs, but her tightly pressed legs didn't relax, and I was afraid of

upsetting her, so I wisely stopped where I couldn't go any further.

I continued, feeling her body relax. I lifted my head, hooking my fingers around

the waistband of her panties, preparing to pull them down. My sister didn't speak, but suddenly reached out and grabbed my wrist.

"You promised I could touch your buttocks however I wanted..."

"But I can't let you see that part of me." Her voice was soft, devoid of her previous anger and arrogance.

"I just want to feel my ass better... Okay, actually I really want to see yours there too... It's just

the two of us at home now, I promise I'll keep it a secret. Sister, please... I really won't cause you any trouble." I

gently pulled my sister's wrist away with my other hand, and she didn't insist anymore. I took one last step and pulled my sister's

panties down to her thighs. My sister's most private place was now displayed in front of me. Had I conquered

my sister?

I didn't have time to think about these questions; the scene before me was quite unexpected. My sister's fair vulva was covered with

so much hair. It was tangled, black, and robust, covering the fleshy mounds and labia majora on both sides of her vulva, extending all the way to

her anus . The fleshy mounds were high and bulging, appearing even whiter and more tender against the backdrop of the pubic hair

. The skin of her groin and labia majora was slightly darker, and the dark red labia minora, like bean pods, stretched from the beginning to the end of her vulva, but were more tender than any I had ever seen in movies

, like two taut, thin lips covering the opening, rather than drooping loosely. To get a better

view , I forcefully spread my sister's legs apart. She let me do as I pleased, neither cooperating nor resisting.

I felt I should comfort her at this moment.

So I moved in front of her, cupped her face in my hands, and turned her towards me. Her face was burning hot, her eyes

tightly closed. I lowered my head and kissed her soft lips, tentatively inserting my tongue into her mouth. I

carefully licked the inside of her lips, still holding her teeth. With a little force, I could squeeze past her teeth and lick her

tongue. While sucking on her saliva, I caressed her breasts. Although I couldn't see their shape,

I could still feel their fullness and elasticity through her clothes. After a while, her mouth responded, first sucking my tongue with

her lips , then slowly extending her tongue to tease my tongue, sweeping back and forth, making

my tongue tingle and itch. After a while, her tongue also entered my mouth, and I groaned, intensifying

my passionate kiss. Soon, my sister would respond in kind.

When we separated, my sister's lips were still slightly parted, glistening with a bright sheen. Her eyes

radiated seductive, alluring light. "Is that enough?" My sister seemed to have woken from her previous ecstasy.

I thought to myself, the real show hasn't even started yet, how could it be enough? I moved on to my sister's buttocks, unable to restrain myself any longer

. I forcefully parted her buttocks and buried my head in her buttocks, licking up and down between them. When

my tongue her anus, I pushed it in forcefully with the tip.

My sister twisted her body, trying to get away from me, and turned her head back, supporting herself on her arms: "Stop, it itches..."

I really wanted to thrust my almost bursting cock into her cunt right now, but I didn't want my sister to feel uncomfortable

afterward , so I decided to give her plenty of teasing. Actually, I had just seen that there seemed to

be some fluid seeping out of my sister's cunt. I parted my sister's legs, moved to the sofa, and lay behind her buttocks, continuing to

bury my face in her buttocks and lick. Perhaps because my sister's anus was cleaned very well, I didn't smell any feces

. When I squeezed my tongue inside, I felt a slightly salty taste. Although I didn't dare to touch it boldly yet, I kept wanting to

smell the scent of her cunt. The real smell of a cunt was much more vivid than the smell on my underwear. Although my tongue was a little stiff and sore,

I didn't want to stop at all. I kneaded her buttocks even harder with both hands. After a long time, my sister

finally groaned under my intense back-and-forth licking.

I stood up from the sofa, pulled down my shorts, and my thick penis sprang out. "The show is about to begin!"

"What do you want to do?" My sister was startled, but her eyes didn't leave my penis.

"Didn't you allow me to touch your butt? I didn't say I'd only use my hands."

"Didn't you say your penis was only a little bit?" My sister rolled her eyes at me, looking very cute.

"I don't know how it suddenly got so big."

"Anyway, I won't do that kind of thing with you."

"Don't worry, I definitely won't do anything reckless... Hey, you've probably seen bigger ones than this, right?" My sister

turned her face away, not answering me. I held my sister's buttocks to prevent her from getting up and running away. Then I positioned my

penis between her buttocks, squeezing her buttocks with both hands, rubbing my penis back and forth.

A wave pleasure made me cry out, increasing the speed of the rubbing.

My sister turned her head, looking at me with a mixture of anger and intoxication. As I thrust into her buttocks, I

leaned forward to kiss her lips.

"No! You just licked that place, it's disgusting."

If I had forced a kiss, I bet she would have given in. But I didn't. I listened to her

and gazed deeply into her eyes, increasing the speed of my thrusts. It seems my stamina isn't just

a few seconds.

"You didn't say it was disgusting when I licked your ass earlier,"

she said, turning her head away again. I pulled back, focusing on rubbing my penis. Before

long , my testicles and prostate contracted sharply, and I quickly pulled back my penis, gripping it and stroking it wildly.

Thick streams of semen sprayed violently onto her snow-white buttocks. Hearing my groans, she turned around and saw my thick

penis ejaculating. Her eyes seemed to ignite with two flames. I squeezed out the remaining semen from my penis and

dripped it onto her anus. This must have been my most intense orgasm.

After I finished, she seemed to realize what had happened and wiped her buttocks with her hand. Looking at her face, her palm was covered in

white semen. "How disgusting!" she exclaimed dramatically, her voice trembling with tears. I got up and wiggled my hips as

I ran . The relief after ejaculating made me slump onto the sofa. Things had come to this point; I didn't need

to worry too much about what would happen next. Although I was still unsatisfied, I didn't plan to force my sister again today. But then I thought,

what if she really got aroused today and wanted to leave when I was helping her tomorrow? She might

end someone else. I had

made it a condition for her to leave when I seduced her. Thinking of this, I decided to take the risk and go all the way today.

I quickly walked to the bathroom door and found it locked from the inside, but it had a keyless

spring lock; I could easily open the bolt with my fingernail. I quietly pushed the door open and found my sister

naked , one leg on the ground, the other raised and propped up on the edge of the bathtub. Her left hand was probing inside her vagina, while

her right hand was spraying the showerhead back and forth between her thighs. She screamed in fright when she saw me suddenly enter and hurriedly pulled her fingers

out. She crossed her arms over her chest, trying to cover her large, white breasts.

I rushed over and hugged my sister, pulling her left hand into my mouth and licking her fingers. My sister struggled to

break free, but I took the opportunity to hug her neck and kiss her lips. I intensely sucked on her lips and saliva, squeezing her full breasts

hard . My left hand reached down to her crotch and touched her, her entire inner thigh slippery

and covered in the sticky fluid flowing from her cunt. My fingers darted through the wet pubic hair for a while, and my sister couldn't help but

wriggle her hips. I held my newly erect penis against my sister's cunt, wanting to test

if it was permissible to penetrate her now.

My sister reached out and squeezed my penis, then suddenly raised her arms and wrapped them around my neck, then twisted

and pressed me against the wall, kissing me frantically, her body undulating against me, her two large breasts squeezing and rubbing against

me, her throat emitting hoarse, beast-like moans. Only then did I notice that my sister

also had thick, dark hair growing in her armpits. I was taken aback by her proactive advances.

My sister reached out and grabbed my penis, straightening it, then stood on tiptoe and brought her vulva closer. With a

downward , my glans and part of my penis slid into her wet vagina. I immediately felt my penis

enveloped in a slippery, warm wetness. Because of the standing position, my penis slipped out of her vagina after only a few twists of her hips

.

I quickly lay down on the ground, and my sister, seeing this, squatted down, guided my penis to her vulva, and thrust her hips

in . As my penis pierced her vagina, my sister let out a long, mournful moan. Then

she began to move up and down rapidly. My penis was enveloped by her tight vagina, and with each thrust, it felt like being squeezed and sucked,

an incomparable pleasure. Because I had just ejaculated, my sensitivity had decreased considerably; otherwise, I

probably . Despite this, I still decided to passively accept being fucked, afraid that I might accidentally ejaculate

if .

My sister was a slut to begin with. Her original reserve, due to family ties, prevented her from ever thinking of doing

this with her real brother. It seems that compared to my sister, I'm an even slutner. Finally, unable to resist the lust, I gave up the fight,

and the carnal desire I had deliberately suppressed burst forth like a dam breaking, no longer under my control. The sense of guilt and shame from violating taboos

only added a wicked charm to the carnal desire. That's human nature; the dirtier and uglier something is,

the more it can arouse a person's most primal and wildest sexual desires. And once this magic is released, a person's civilized mask

crumbles like dry leaves.

"Ah... little brother... your cock has finally fucked sister... fucked sister's cunt

... fuck harder... fuck me to death... oh... fuck sister to death." My sister's ass rose and fell faster and

faster, her fleshy buttocks slapping against my inner thighs with a slapping sound. After a while, probably tired, she sat on my lap and

moved back and forth, side to side, or in a circular motion. Her breasts bounced with her movements, dazzling to

the eye.

"Ah...ah..." my sister moaned hoarsely. I felt the juices from her vagina flowing down

my penis to my inner thighs. I really wanted to know what a woman's vaginal fluid tasted like, so I begged my sister to let

me taste it. Without hesitation, my sister got up and took two steps forward, squatting above my face. Her swollen, red vulva was

now visible, her labia and pubic hair covered in white foam. She squatted down again, her entire vulva

covering my lips.

I sucked on my sister's vulva like a starving ghost. Licking a vulva was a different experience from kissing;

it felt softer. I would pinch her lips together and suck the soft flesh into my mouth, sucking for a while and then licking it

indiscriminately . The vaginal fluid tasted similar to egg white, slippery, slightly salty, and with a faint fishy smell.

"Big dick little brother, does my cunt taste good?... You licked my cunt clean...

Is my cunt horny?... Oh... you horny little brother, you're so good at licking... Your mouth is so cute... Ah... I can't take it anymore

... I want you to keep fucking me... My horny cunt is so itchy... You can eat me whenever you want...

Now fuck me first..." Unable to bear the emptiness inside her cunt, she got up and sat back on my dick

to continue riding me.

After a few thrusts, she couldn't help but moan again. "...Oh... It feels so good. You horny little brother... Thrust harder

, fuck my horny cunt to death, fuck my big horny cunt raw..." Not long after, she suddenly stopped thrusting,

the muscles in her thighs trembled violently, her buttocks pressed down desperately, her horny cunt gripped my dick tightly, trembling in waves.

Spasms. "Ah...no...let me die...fuck me to death, fuck me to death, fuck me to death...ah..." She

leaned down, kissing my mouth and sucking hard, as she climaxed. I intertwined my lips and tongue with hers, feeling

her climax. After about ten seconds, her trembling and spasms gradually subsided. Exhausted, she collapsed on

top of me to rest.

Giving her a moment to catch her breath, my penis remained obediently inside her vagina, not moving. I only

used it to caress her back. When my hand reached her buttocks, I lingered, reluctant to leave.

When my right index finger brushed against her anus, it felt slippery with vaginal fluid, so I pressed down, and with the lubrication of the

fluid suddenly slipped into her flesh.

"Mmm...no..." my sister gasped.

Her anus, feeling the intrusion, contracted violently, like squeezing out feces, causing her vagina to contract sharply as well

. "This is really fun," I thought to myself, and after a few more taps, I finally

pulled my fingers out after my sister protested.

"Sister, your little cunt hasn't been fucked enough yet, has it? Get up and let my cock fuck you for a while." My sister got

up and tried to lie down on the floor. I quickly stopped her: "It's too cold here, how could I bear to let you lie here? Go to the sofa

." My sister obediently got up, and I hugged her, my big cock erect, and we returned to the living room. As soon as my sister sat on the sofa,

she hooked her arm around my neck and kissed me passionately. Then my sister sat sideways on

the sofa , leaning back and resting her head on the armrest, her arms holding her knees, spreading her legs into an M shape, her cunt completely exposed

, welcoming my entry.

I knelt between her legs, grabbed my cock, and thrust it into her cunt. The first time I actively thrust into a woman's cunt, the feeling was

indescribable. I couldn't help but marvel at the ingenuity of creation; with each thrust, the folds inside her cunt scraped against my cock , sending shivers of pleasure through

me. My penis, moving in and out, scraped against the walls of her cunt, driving my sister to ecstasy. Soon,

she began to wriggle her hips to meet my thrusts, and hoarse yet excited moans escaped her throat once more. Her cunt,

wet with fluid, made gurgling sounds.
