My sister is fucked by someone else (family incest adult novel)

On a sunny afternoon, two students who skipped classes were chatting and gossiping on the roof of the school building.

A Guang, maybe you can come and fuck my girlfriend... When I heard Senior Xiao Zhen say this, I thought it was a low-level joke.

But seeing his serious face, I began to wonder if he was really crazy.

Hello! I'm serious, please don't look like you don't believe me.

Senior, you usually seem stingy and have never even treated me to a drink. Now you give me your beautiful girlfriend for free without any reason. How can people believe it? I didn’t say I would give Yizhen to you for free... Xiao Zhen smiled lewdly with ill intentions: If you want to fuck my pure and beautiful Yizhen, then let your flirtatious sister fuck you as well.

Oh, I've known for a long time that Xiao Zhen had bad intentions towards my sister. Ever since he saw her at my house last time, Xiao Zhen has been obsessed with her. But I didn't expect that he would be willing to exchange her for his girlfriend! My sister is not a show-off! She is an elegant college student, and what's more, she already has a boyfriend.

No matter what, I just want to fuck her... I really want to take off her clothes and look at her fair and delicate skin, her well-proportioned figure, I really want to lick those proud, erect and round breasts, I really want to use my huge cock to penetrate her tight and wet pussy, I really want to hear her soft and seductive moans... Ah! No matter what, I just want to fuck your beautiful sister, let me do it! Xiao Zhen is probably going crazy.

In fact, I am also quite interested in Xiao Zhen’s girlfriend. Not only is she beautiful, but according to Xiao Zhen... she is also a little slut! She often tried various exciting ways of having sex with Xiao Zhen. The most exaggerated thing was that she was said to have been gang-raped by two strangers and reached orgasm five or six times.

But no matter what I say, I dare not convince my sister to let anyone do it! Senior, it’s not that I’m stingy and don’t want to help you, but how could I ask my sister to have sex with someone else? There is no stance! That’s right, then can you at least help me ask her out? I'll figure out the rest myself.

What if someone makes an appointment for you, but you still can’t do it? Then I accept it, Yizhen can still be done by you.

This seems to be a good idea. I just asked my sister out and didn't force her to be raped. Whether she can resist depends on herself... Then it's settled! After school, Xiao Zhen handed me a pair of white women's underwear and a bunch of keys.

Hehe, done.

I have made an appointment with Yizhen, and she is waiting for me in my dormitory. Go and tell her later that I will be back later. Of course, she is now a beautiful slut without underwear. The rest is up to you. Call me when you are done.

Xiao Zhen is really efficient. Looks like I'm going to have good luck in love today! Although I'm not sure if I can ask my sister out, but with such a temptation... I might as well do it first! I ran to Xiao Zhen's dormitory as fast as I could, opened the door, and sure enough, the beautiful Yi Zhen was already sitting inside.

Hi! A Guang, why are you alone here? Where is Xiao Zhen? Yizhen's voice is so sweet, as if she is acting coquettishly. I began to imagine how deadly it would be to moan in that voice! oh! The senior has something to do and said he will be back later.

So... sit down, don't stand there.

I'll make you a cup of coffee.

OK...OK, thank you.

Yizhen was wearing a school uniform. The custom-made skirt was particularly short, revealing a pair of charming legs. She was also wearing white socks on her feet.

The white translucent top clearly outlines the lines of the bra and the slender waist, which is so adorable... What are you looking at? ...Yizhen blushed, brought two cups of coffee and sat down in front of me.

She lowered her head, her big watery eyes blinking, her pink lips naturally closed. She looked like a pure and shy little girl. She was really beautiful.

In order to avoid this embarrassing situation, I wanted to take a book out of my bag to read.

But when I opened the schoolbag, I saw Yizhen's underwear, and then I realized that under Yizhen's super short school skirt, there was only a bare little butt.

This little slut is really not simple! She is clearly naked, waiting for her lover to come back and fuck her, but she pretends to be innocent and shy. This is really the highest level of lewdness! While looking at the lovely Yizhen, I unconsciously picked up the cup and accidentally spilled the coffee. The hot coffee splashed all over Yizhen's school skirt and uniform.

ah! I'm so... so sorry, I'm sorry... I hurriedly took the tissue on the table and wiped it for her.

No...it doesn’t matter.

Yizhen was startled by my action and sat there motionless.

When I was wiping Yizhen, I took the opportunity to linger for a long time on her exposed white legs and the school skirt fabric on her lower abdomen.

Seeing that Yizhen had no intention of resisting, I became bolder and used my fingers to tease her private parts through her skirt.

Not long after, Yizhen's body gradually softened and she fell powerlessly on me. I hugged her and continued to caress her.

Yizhen's big eyes were half-open and half-closed, looking at me blankly, her breath was as fragrant as orchid, and she kept gasping for breath.

I couldn't help but get closer to her and gently kissed her soft lips. Unexpectedly, she closed her eyes, stuck out her naughty little tongue, and responded to me enthusiastically.

So I kissed her and put my hand into her skirt.

Since Yizhen's panties had already been taken off by senior Xiaozhen, I could easily touch Yizhen's soft pubic hair.

oh? Yizhen is a little slut, how can she not wear underwear? I teased her on purpose.

No...no, that...that’s Xiao Zhen...She blushed and shook her legs, trying to avoid my hand.

Don't explain. I'm going to punish you.

As I said that, I dug my fingers into her small tender hole. As her struggles became increasingly weaker, her pussy juice began to flow out.

Yizhen buried her head in my chest, and her panting sounds gradually turned into soft moans.

Ah...ah...ah...Brother A Guang...Yi...Yizhen...I can’t stand it...No...don’t dig Yizhen anymore...ah...ah...I pulled up her shirt and pulled up her bra, and Yizhen’s snow-white breasts were exposed.

Yizhen's breasts are big and round, standing on her chest. Because she is young, there is no tendency for them to sag, but instead they stand up proudly.

There were two small pink bumps located right in the center of the breast. They looked so delicate and adorable that I couldn't help but eat them in one bite.

Ah~ Yizhen cried out when I licked her, and then her nipples slowly protruded and became slightly harder.

I observed carefully and found that Yizhen's nipples were bigger and more erect than those of other girls. Maybe it was because Xiaozhen often took care of her.

I found that my dick had become hard due to Yizhen's lewd look, and a few drops of liquid had come out of the glans.

Normally, if I were to have sex with other girls, I would lick their vaginas before starting to penetrate them. However, with a girl as beautiful and slutty as Yizhen, I simply could not help myself and had to penetrate her immediately.

So I quickly unzipped my pants and took out my dick. Without even taking off my pants, I lifted Yizhen's right leg and inserted my long-erect big dick into Yizhen's wet pussy in one go.

Yizhen screamed, and her pussy trembled a few times. A lot of liquid leaked out and slowly flowed down from the hole that I was inserting into. Then I realized that she had already reached orgasm.

Wow! You're exaggerating. It doesn't work right after I put it in? Yizhen was breathing weakly, just looking at me with a very seductive look, her legs trembling slightly.

At this time, neither of us actually took off our clothes, but she was wearing a skirt and no underwear. I pulled down the zipper and took out my dick, so there was no problem fucking her. Moreover, I had already pulled up Yizhen's clothes, so her breasts could be easily played with by me.

I didn't care whether she had an orgasm or not. I lifted my dick and started pumping. Yizhen's white right leg was carried on my shoulder and her tender pussy was being pounded wildly by me.

Yizhen lay on her back on the floor, moaning as I fucked her. Her pussy contracted in waves, sucking my dick so comfortably.

Ah...ah...ah...brother...brother...Yizhen can’t...take it anymore...why...why are you still plugging away...ah...ah...Yizhen will be fucked to death by you...ah...Yizhen called out softly in a gentle voice, and I was thinking that maybe there is no other woman who can call out as beautifully as she does! How could I bear hearing the little beauty's call like that? After pumping her for more than twenty times, I pulled out my penis and shot a large amount of semen onto Yizhen's pretty face. Yizhen's face was covered with my semen and she fell to the floor, gasping weakly.

After I rested for a while, I saw Yizhen still lying on the ground, gasping for breath. Her lovely breasts did not collapse because of lying down, but were still standing upright. There was milky white semen remaining on her pretty face... Gradually, I got an erection again.

I quickly took off all my clothes in two or three moves, and then took off Yizhen's clothes. Although she wanted to resist, she was powerless and let me strip her clothes off.

Then I used Yizhen's shirt to gently wipe the semen off her face, and rode on her, placing my long and hot cock between her plump breasts. Then I held her soft and tender breasts with my hands, squeezed them together, and began to swing my waist so that my penis moved in and out of her cleavage.

oh! Is this breast sex? If I hadn't met a busty slut like Yizhen, I really wouldn't be able to have fun! After five or six minutes, I found that Yizhen began to struggle again. However, it was more like pretending to be shy rather than struggling, because she was not resisting very hard at all.

So I climbed up from her, put her in a kneeling position with her back facing me, and started licking her private parts.

It turned out that Yizhen's labia also had a lovely pink color like her nipples. After turning over the two labia, a lot of liquid flowed out, and Yizhen was also moaning softly.

I started licking Yizhen's little asshole with my tongue, and then licked towards her clitoris. When I licked her clitoris, Yizhen screamed particularly seductively.

Then I used three fingers to dig into her tender vagina at the same time. Because Yizhen's vagina was very tight, I had to use a lot of force to push three fingers in at the same time. Yizhen screamed in pain from my fingers.

After digging for more than ten minutes, Yizhen reached orgasm again and her vaginal fluid sprayed all over my hands. I didn't give her a chance to catch her breath and immediately inserted my dick into her from behind.

Ah...ah...Yizhen can’t take it anymore...ah...I can’t bear it anymore...ah...ah...ah...how...how...is it like this...ah...my pussy...is so...so swollen...it’s...it’s all the way to the bottom...ah...Yizhen was screaming in pain from my fucking, not even afraid of the neighbors hearing her.

Since I had just ejaculated once, I didn't want to ejaculate this time after fucking her for more than half an hour. Instead, Yizhen was brought to orgasm by me again.

Leaked again? Yizhen is so cute when she looks lustful... Ah... Brother A Guang... why... why haven't you cummed yet... Yi... Yizhen is almost passed out by you... Yizhen, can Brother A Guang play with your little butt? I said this while fingering her asshole.

Well, but you can’t let Brother Xiaozhen know...Okay, Yizhen, be good, I won’t tell.

Then Brother Guang, please be gentler... I know.

As I said that, I pulled out my penis that was soaking in Yizhen's wet and tender vagina, and pushed the huge glans outside her asshole.

Because Yizhen had secreted a large amount of vaginal fluid, the anus and penis were lubricated sufficiently. I inserted it gently, and half of the glans entered Yizhen's anus.

Ah...Yizhen let out a long, tender cry.

I pushed my penis forward slowly. Although Yizhen's anus was tighter than her vagina, due to sufficient lubrication, I could actually insert the entire penis in! Yizhen, your little butt is so tight, brother is going to start thrusting... um... brother... brother... thrust faster... Yizhen wants it to come big... ah... Yizhen, be good, brother will thrust very quickly, just bear it when it hurts, okay? After pulling out half of my penis, I inserted it again and started pumping, gradually increasing the speed of fucking Yizhen's asshole.

Less than a few minutes later, Yizhen reached orgasm again with a moan, and this time there was no finger or penis blocking her vagina, and the vaginal fluid gushed out directly from her vagina like a small fountain.

I was surprised at Yizhen's sensitive physique that could easily lead to orgasm. It was really fulfilling to have sex with a girl like this... I continued to have anal sex with Yizhen. I felt a little reluctant to let her continue being fucked by me, not to mention that her asshole was so tight. I was also comfortable enough, so I used all my strength and rammed her hard from behind. After another ten minutes, a stream of semen shot into her anus.

Phew...that's awesome! I said.

And Yizhen had already been unconscious from my sex.

I took her bra and put it in my schoolbag, then left Xiao Zhen's dormitory and used a public phone to call his cell phone to contact him.

It is said that Xiao Zhen went back and had sex with Yi Zhen again that night, and Yi Zhen took a day off sick the next day because her labia became red and swollen due to the continuous torture from the two of us.
