My Wife's Sister (Family Incest Adult Fiction)

One day Caiyun said to Ajie:

"Honey, my sister told me that she hasn't had sex with her brother-in-law for a long time. They seem to have been living a sexless life. Will we continue to be like this in the future?"

Ajie listened and laughed and said:

"No, I will be obsessed with you forever. I like every inch of your skin, and I like the feeling of having sex with you, especially your big ass.

I can't put it down. I am as unintelligent as my brother-in-law."

However, although Ajie answered Caiyun like this in his heart, he was also secretly paying attention to Caifen. Caifen's unintentional exposure several times gave Ajie a feast for the eyes.

In Ajie's mind, although Caifen is a married woman who has given birth to children, and her figure is not very good (women who have given birth to children have big buttocks),

But Caifen has a pair of breasts that are bigger and softer than Caiyun, and a big butt that feels super good to fuck. And Ajie just thought that if he could have sex with his wife's sister one day,

That was incest, which made him even more excited unconsciously, and also slowly awakened the evil side of Ajie's heart.

But he could only keep it in his heart. He really wanted to tell Caiyun that he had sexual impulses and fantasies about his sister, and he imagined that Caiyun would help him to persuade his sister.

But that was just a fantasy after all, and he didn't dare put it into action because he was afraid that he would be scolded and not understood by his wife, which would affect his marriage life. But as the days passed,

The desire for incest in Ajie's mind became even stronger, but he was not sure whether Caifen could accept such a relationship; whether Caifen had such a strong sexual need.

If so, his hope would be even stronger.

Finally one day, by chance, Caifen told Ajie that she wanted to watch the animation "Howl's Moving Castle". Did Ajie have it? Ajie thought that the opportunity had come.

He made a decision right then and there; he decided to give it a try and follow his own desires.

He found a day when Caifen was alone at home and went to see her, saying:

"Big sis, I borrowed the animation you want to watch from my colleague. Do you want to watch it?"

"But I need to use a computer to watch it. I haven't converted the file yet. Can you lend me your computer?"

Caifen didn't doubt his words and said yes, and took Ajie to the study. Arriving in the study, Ajie turned on the computer, installed the USB hard drive and said:

"Sister, would you like to come and take a look first?"

Caifen said, "Okay! I have nothing to do now anyway. I don't have to open the store until 12 o'clock."

Little did she know that this was a trap designed by Ajie. He deliberately put some pornographic films in the USB hard drive to arouse Caifen's potential desire. After Ajie installed the USB hard drive and opened the directory, he said:

"Hey! What is this? Why are there other files? I don't know what this is. Do you want to take a look at it together, big sis?"

Caifen said, "Well, whatever."

Ajie smiled secretly in his heart and opened the file. The computer screen showed a scene of a man and a woman having sex, with the girl sucking and licking the boy's genitals.

This scene had a huge impact on Caifen, who had not had sex for a long time. Moreover, the person sitting next to her was her sister's husband, which felt really strange.

Ajie also secretly glanced at Caifen a few times and found that Caifen was staring at the computer screen without any intention of turning it off. He knew that his plan was gradually taking effect.

After a few minutes, Ajie said to Caifen:

"Big sis, do you want to watch more? I want to go to the bathroom."

Caifen also realized that she had lost her composure and said quickly:

"No, Ajie, your colleague also put porn in it, why don't you turn it off?"

Ajay said:

"Sister, wait a minute, I need to go to the bathroom first. I've been holding it in for a long time."

"Oh, it hurts," Ajie shouted as he got into position in the bathroom.

Caifen heard Ajie's screams from outside and knocked on the door and asked:

"What's wrong, Jack?"

"Sister, I fell down and I can't stand up. It hurts so much," said Ajie.

"What should we do then?" Caifen said.

"Big sister, can you come in and help me?"

"Me? That's not convenient." Caifen said.

"But, big sister, I really can't stand up. Come in and help me up! It hurts."

"All right"

After Caifen opened the door, he found Ajie sitting on the ground, looking miserable. But I also saw Ajie's erect little brother.

Cai Fen thought to herself, "Wow, it turns out that Ajie's little brother is so big, at least 15-16 centimeters long, with a big and red glans. I wonder what it would feel like if it were inserted into my vagina."

But because of modesty, he still said to Ajie: "Ajie, put on your pants first."

Ah Jie said, "Sister, I can't stand up, how can I put on my pants? Please help me first."

So Caifen helped Ajie up, and Ajie took the opportunity to pretend not to care and touched Afen's chest, giving Afen further stimulation. The two men staggered over to the sofa bed and sat down.

As soon as they sat down, Caifen asked Ajie, "Are you okay? Do you want to see a doctor?"

Ajie said, "It's okay, just take a rest and see if it works. If it doesn't work, I'll go see a doctor later. But I'm sorry, big sister, I accidentally touched your breast just now."

After hearing what Ajie said, Caifen's face suddenly turned red and she quickly said, "It's okay, you didn't mean it."

Ajie thought the time was almost right, so he quickly moved his body and sat next to Caifen. Then I said to Caifen: "But sister, your breasts are really soft. If I tell you,

I did it on purpose just now, are you angry? "

Caifen didn't expect Ajie to be so bold as to say these words to him. For a moment he was unable to react.

Ajie continued, "Actually, sister, I have always had fantasies about you and have been secretly paying attention to you. I also know that brother-in-law rarely has sex with you. Sister, don't you have any needs?"

As Ajie spoke, he touched Caifen's thigh.

Ajie's words made Caifen at a loss for words. Coupled with the feeling of Ajie caressing her thighs, Caifen's desire gradually overcame her reason.

"Hey, Ajie, I'm a woman too, but your brother-in-law doesn't want to, so..., in fact, how could I not want to!"

"Then sister, I think I can replace my brother-in-law and give you considerable satisfaction. If you are willing," said Ajie.

"Ajie, you are my sister's husband, we can't do this!" Although Caifen said this, she had no intention of stopping Ajie. Because Ajie's touch felt so comfortable.

It gave him an electric shock-like feeling in his lower body.

And seeing that Caifen said no but had no intention of stopping him, Ajie became even more certain that he could have sex with Caifen and fulfill his dream.

So he became bolder and moved his hand towards the inside of Caifen's thigh.

"Sister, you have needs, and I have always had fantasies about you. Please, can you?"

"You have fantasies about me? Why? I don't have a good figure and my butt is big, how could I..."

"Sister, if I don't tell you, you don't know. Although your butt is big, I am particularly fascinated by your big butt. I often fantasize about you. There have been several times when I smelled your underwear in your bathroom.

Bra, masturbation, self-defense. I thought it would be so comfortable if I could have sex with you one day. "

Caifen was even more surprised. She never expected that her sister's husband was so obsessed with her, and she never expected that she was so sexually attractive.

In addition, Ajie's penis is indeed much bigger than her husband's, and she really needs it, so as Ajie moves, Caifen's defenses slowly break down.

"Big sister, you can't help it, you really want to make love, I put down the shackles of the world, everyone is happy, and it won't hurt others. It's just a matter between the two of us.

How would anyone know if you don’t tell anyone? Just be happy! "

"Don't be silly, we are in-laws, doing this is incest, we can't... Ming..."

"I'm telling you, Caiyun and I haven't had sex for a while. I don't have the sexual desire to have sex with her, but every time I see you, I have the desire to have sex with you.

I have to masturbate immediately. I know this is so perverted, but I really like you, just treat me as your husband. "

Ajie began to take off Caifen's clothes and started licking her toes, then calves, thighs, and belly button. He then went up to suck her breasts, and both nipples became hard.

Caifen kept shouting "no" but she was powerless to struggle. Ajie ignored her and slowly licked Caifen's most important part, then spread her legs and exposed her beautiful hairless pussy.

The slit was oozing with sexual fluid, and the two labia majora began to become wet and reflective. Ajie used his fingers to touch the slit.

"Oh...no...don't..." Caifen started to get excited, but continued to say no! She said no with her mouth, but her pussy was so lewd that it started to leak juice.

Ajie used his fingers to spread her labia majora, stuck out his tongue to lick her vagina and labia minora, and finally sucked her clitoris.

"Ah...ah..." Caifen trembled: "Well...don't...ah...no...no...can't...ah..." She pushed Ajie's head away with her hands, or pulled Ajie's hair.

Ajie felt so excited and sexy looking at her that he got goose bumps all over his body and his vaginal fluid flowed from her vagina to her anus and then onto the bed sheets.

Ah Jie continued to lick Cai Fen's pussy, sucking on her clitoris, and thrusting her vagina with his tongue, even using his most powerful move, the "Dragon Drill" -

Caifen couldn't hide it at all, Ajie knew that now was the best time to fuck Caifen's pussy!

He used a pillow to raise Caifen's buttocks, spread her legs apart, held his penis and placed it on her vagina, thrusting it forward.

Caifen suddenly came to her senses and said, "Ajie, no... I beg you not to put it in. I am your wife's sister. This is incest and cannot be done."

Ajie said, "What are you afraid of? We are all adults. How can anyone know if we don't make it public? Besides, we all need it. Just treat me as your husband.

Besides, we are not related by blood, so how can it be considered incest? And sister, I really like you. "

"No! Ajie, we can't turn back once we make a mistake. We will never be able to hold our heads up high again."

"Why do you want to turn back?! I don't care. I can't stand it anymore. You don't have to stand it anymore."

"Ajie, no, you have to wear a condom." Caifen said.

"Hey, sister Yue, it's okay. It feels better without a condom, and now we have the emergency contraceptive pill, so you don't have to be afraid."

"Hmm...mm...ah..." Seeing Caifen closing her eyes and letting out a series of moans, Ajie didn't care about anything else and aimed his glans at her vagina and slowly inserted it.

"Oh...it feels so good!" After inserting the entire dick into her, Ajie did not pull it out immediately. He wanted to carefully feel the feeling of fucking Caifen's pussy.

"Ah..." Ajie began to thrust slowly. Because there was a lot of love juice in Caifen's pussy, it was very slippery and warm, and Ajie fucked her until she made a "sizzling" sound. Ajie saw Caifen biting her lower lip with her teeth.

"Mmm...Mmm...Mmm...Mmm..." She made a "Mmm" sound every time Ajie thrust into her.

Ajie thought, "Okay, I'll do it with all my strength. When she's about to climax, I'll lift her legs up and put them on my shoulders, just like doing push-ups, and her big butt will be raised high.

Let me insert my entire dick, push it hard, and push it all the way to the bottom.

After Ajie ejaculated, he did not pull out his cock immediately. He just lay on Caifen, panting, and Caifen was also panting.

"Ah! There's really no comparison. This time the orgasm was so good. I wonder if it's because the person I fucked is my wife's sister?"

"Ajie, why did you ejaculate inside me? What if I have a baby? Please help me clean up the semen." Caifen said

Ajie immediately took a tissue to help Caifen wipe it. Semen kept flowing out while she was wiping. It was so enjoyable.

"Big sister, is it comfortable? I will give you more pleasure in the future."

"Oh!...I shouldn't do that. I can't face anyone."

"Big sister, if you don't want to do it, you've already done it. Why are you still thinking so much? Just open your mind and accept the reality! Besides, if you don't say it and I don't say it, no one will know."

At this time, one of Ajie's hands was on Caifen's inner thigh, and the other hand was touching Caifen's chest.

“Ajie, ah…, that’s true, but… mmmmmmm…”

Ajie didn't give Caifen any chance to speak again. He put his mouth on Caifen's lips and sucked hard. And Caifen's defense was slowly broken down under Ajie's wave after wave of attacks.

With the help of Ajie's hands, her body twisted involuntarily again.

At this time, Ajie said playfully in Caifen's ear: "Big sister, I want to fuck you again! You have to be mentally prepared!" As Ajie said this, he moved his hand to Caifen's buttocks.

Caifen couldn't help but move her round buttocks forward.

Ajie smiled and moved his fingers between Caifen's legs to rub her vagina.

Caifen felt Ajie's fingers on her vagina. Then, Ajie touched Caifen's round buttocks with one hand and spread her legs with the other hand, revealing her lush vagina.

He used his fingers to separate Caifen's slightly moist labia and inserted his fingers inside.

"Oh...oh...um...um..." "Ajie, um...God, it feels so good...um..." Her voice was weak, and her hips involuntarily raised up while she was lying there. Ajie knew exactly what to do at this time.

He focused his attack on Caifen's clitoris, constantly teasing that little bit of pleasure.

"Oh...oh...that's it...baby...harder...ah...ah..." Her body swayed, and her pussy couldn't help but tighten around Ajie's fingers. Ajie looked at Caifen's buttocks.

Like a delicious peach, he put his mouth on Caifen's left buttock and took a gentle bite. The physical pain and the lustful feeling in her heart made her a little crazy.

"Ah...Ajie...don't bite...big...sister..."

"Ah...faster...ah...harder...right there...grind harder..."

As Caifen requested, Ajie used two fingers to rub Caifen's clitoris, and Caifen moved her fingers even more vigorously.

"A little more...ah...ah...ah..." Ajie felt that Caifen was approaching orgasm again. From her sweaty buttocks, he could smell the lustful odor emanating from between Caifen's legs.

"Sister, can you lick my little brother too?" Ajie said as he changed to a 69 position and put his big cock in front of Caiyun.

"Wow...Ajie, your cock is so big, so thick, and so strong! I really love you..."

Caifen kept stroking Ajie's penis with her hand, sometimes fast, sometimes slow, which made Ajie almost want to pick her up and have sex with her.

Ah Jie turned around and saw Cai Fen closing her eyes, looking intoxicated. Then she rubbed her cheek on the penis, and finally saw her slowly extending her tongue and began to lick the glans.

Then she opened her mouth and took the entire penis into her mouth.

Wow! It feels so comfortable, Caifen’s mouth is like a suction cup, sucking up and down.

"Slurp... slurp..." The sound of sucking continued to come out of Caifen's mouth.

After 5 minutes, Caifen could no longer bear it, turned around and panted to Ajie, "Ajie... hug me, kiss me..."

Ajie hugged Caifen and slowly moved his lips in front of Caifen. When the four lips were pressed together, Caifen involuntarily put her tongue into Ajie's mouth and stirred it wantonly and madly.

Ajie also gently sucked Caifen's tongue, and the two of them sucked each other back and forth. The kiss lasted for more than 10 minutes.

Then Caifen asked Ajie to lie down on the sofa bed, looked at his big cock, and said to me lewdly: "Ajie... let me serve you well! My dear brother!"

Caifen lay down between Ajie's legs again and used her dexterous hands to constantly stroke my big cock up and down, sometimes fast, sometimes slow, and sometimes gently stroked my balls and anus.

The movements were so light and gentle, as if she was afraid of hurting Ajie by accident.

Ajie gradually realized that Caifen had already regarded his big cock as her favorite. All of a sudden, Ajie deeply felt that he was the happiest man in the world. At this time, Caifen also buried her head between my legs.

She began to taste my big cock, which was full of blue veins and red and hot.

Caifen used her flexible tongue to lick Ajie's glans and urethra back and forth again and again. Then, Caifen put Ajie's big cock into her mouth and began to stroke it up and down.

Ajie felt an indescribable comfort and pleasure.

Ajie then sat up and quietly enjoyed Caifen's flute performance. Watching his big cock going in and out of Caifen's cherry mouth, with the regularity of a piston.

Cai Fen spit out the big cock and asked lewdly, "Ajie...does elder sister feel comfortable with you like this?"

Ah Jie panted and said to Cai Fen, "Big... Big sister... It feels so good... So... So good... I didn't expect your oral sex skills to be so good... So comfortable... I feel like I'm floating in the air."

Cai Fen smiled and said, "The insertion later will make you feel more comfortable and even more like a floating celestial being."

Caifen pushed Ajie down on the sofa bed again and put the big cock into her mouth, and started stroking it up and down.

Ah Jie panted and told Cai Fen: "Big sister... let me taste your pussy again... okay?"

Then, Ajie and Caifen turned into the 69 position again. Ajie once again inserted his fingers into Caifen's flooded vagina, pumping them back and forth quickly and began to lick Caifen's little pistil.

Caifen’s moans rang out again.

“Hmm…hmm…ah…ah…so comfortable…hmm…ah…ah…”

Caifen's love juice flowed more and more. She turned her head and panted to Ajie, "Ah... Ah... Ajie... I... can't stand it anymore... I want... I want... I want to fuck you..."

After saying that, she turned around, held my big cock and sat down.

"Ah...oh...a big cock is just...different...hmm...hmm...comfortable..."

Ajie felt that her big cock had filled Caifen's pussy completely, leaving no space at all. Caifen's pussy is so tight and has such strong suction.

It seemed as if it was going to suck Ajie's big cock into a bottomless abyss. Caifen began to frantically use her pussy to move Ajie's big cock up and down. Caifen's 34C plump breasts also kept rising and falling due to her intense movement.

As she was shaking, Ajie's hands began to rub her breasts and nipples.

Cai Fen panted and asked, "Ah...Ah Jie...Big sister...are you...comfortable...doing this way? Are you...happy?"

Ah Jie also panted and responded: "Big... Big sister... fucking me like this... is so comfortable... and so pleasant... Big sister's little... little hole is really great...

You made me feel so comfortable... so good..."

After hearing what Ajie said, Caifen started to use her pussy to stroke Ajie's big cock even more crazily.

“Mmm…mmm…big…cock…it fills me up so well…so full, so full…ah…ah…”

“Hmm…oh…ah…ah…I can’t take it anymore…oh…oh…hmm…ah…”

Suddenly, a stream of hot vaginal fluid poured onto Ajie's glans, and Ajie knew that Caifen had reached orgasm again. But Caifen did not let her pussy leave Ajie's big cock after the climax.

Instead, he continued to stroke Ajie at a slow speed. Maybe it’s because it’s too intense! Caifen was already lying on Ajie's body, kissing his nipples, ears, neck and lips frantically.

Ajie could feel Caifen's wildness and craziness even more.

Cai Fen gently told me: "Ah Jie, from tonight on, our relationship is no longer the same as before, how will you treat me?"

Ah Jie hugged Cai Fen tightly and said, "Sister, I will still be the same as usual in front of others, but in private, I will often use my big cock to fill your little hole, so that your life will no longer be empty.

No longer lonely. "

Cai Fen said to A Jie in a teasing tone: "It all depends on how you perform. Don't let me down!"

Ajie smiled lewdly and said to Caifen, "Today, I will make your pussy submit to my big cock."

After saying that, Ajie gently picked up Caifen and placed her on the soft bed. Caifen also put her legs on Ajie's shoulders, ready to welcome his insertion.

Ajie slowly pushed his big cock into Caifen's pussy and started pumping back and forth using the method of nine shallow and one deep.

“Oh…big cock…it fills me up so full…mmm…mmm…ah…ah…it feels so good…mmm…mmm…”

Ajie also placed his hands on Caifen's chest and gently scratched Caifen's dark brown nipples with his fingertips.

"Mmm...ah...mm...oh...Ajie...really...really good at fucking...it makes me...feel so good...ah...mmm...quickly...

Fuck me harder...faster...harder..."

After hearing what Caifen said, Ajie increased his strength and started thrusting quickly. Caifen also twisted her waist wildly in response to Ajie's harder and faster insertions.

Caifen was like a hungry she-wolf, trying desperately to swallow Ajie's big cock with her pussy, and Ajie was also desperately fucking Caifen's pussy hard, as if he wanted to break it. Caifen's moans became louder and louder, and Ajie knew that Caifen was completely immersed in the world of sex.

"Hmm... Hmm... Ah... Oh... Hmm... Ajie... Well done... I... I... Ah... Hmm... Love... Love you so much... Ah..."

Under Ajie's desperate attack, Caifen reached orgasm again. Caifen hugged Ajie tightly and kissed him madly, while Ajie's back was already covered with hundreds of bloody scratches from Caifen's hands.

Cai Fen panted and told me: "Ajie...you are really good at...really good at...fucking...you fucked me so hard..."

Perhaps this position is the easiest for a woman to reach orgasm. Ajie thrust back and forth about a hundred times, and a stream of hot vaginal fluid once again poured onto his glans.

He knew that Caifen had reached orgasm again, but instead of pulling out his big cock, he penetrated Caifen's pussy even faster and harder.

Caifen's love juice slowly flowed out of her pussy as he moved in and out, wetting Caifen's big ass.

“Oh… Ah Jie… you’re so good at… you’re so good at fucking… Big sis… I… am… about to orgasm again… hurry… hurry up and do it harder… um… um… ah… oh… oh…”

Ah Jie also panted and said to Cai Fen: "Big... Big sister's pussy... your pussy makes me... so comfortable... so... so happy... um... ah... Big sister's... pussy is so great..."

Cai Fen said to A Jie frantically: "Just let me... reach... climax... with you... um... ah... ok... ok?"

As a result, Ajie fucked Caifen's pussy faster. As Ajie fucked her like crazy, Caifen climaxed again. When her vaginal fluid once again splashed onto Ajie's glans,

Cai Fen said to Ajie crazily: "Ajie... Ajie... Oh... Um... Cum in... Cum in my mouth... Mouth, please... I... want to swallow... your... semen... semen

...Hurry...let me suck...suck your...big cock..."

So Ajie left Caifen's pussy and lay down on the sofa bed. Caifen lay between Ajie's legs.

She began to suck Ajie's big cock with her cherry-like mouth and flexible tongue. And Ajie also treated Caifen's cherry mouth as a pussy.

Ajie's semen was like nectar, and Caifen swallowed it all without wasting any. Ajie deeply felt that Caifen had already merged with him.

He also believed that he was the only one who could satisfy Caifen's sexual needs.

After a short rest, caressing, sweet words and flirting, Ajie picked up Caifen and walked into the bathroom.

I will never let Caifen feel empty and lonely. After Ajie had sex with Caifen again, the latent incest factor in his mind was aroused again. He looked around and found that the surroundings were so vast.

His wife Caiyun's eldest brother has to go to the mainland for work, and his wife makes him eager to go. Of course, this is the beginning of another true story.
