My affair with my sister-in-law (family incest adult novel)

The first time I met my sister-in-law, she was 24 years old. At first sight, I felt that what my wife said to me was not an exaggeration. My sister-in-law was indeed a beauty.

My wife is considered to be of above average appearance, but my sister-in-law is slimmer and 5 cm taller. She has big eyes and is very good at putting on makeup and dressing herself up compared to my wife. There is a different temperament as someone who graduated from an art school.

The only pity was that she already had a boyfriend, and I wasn’t the type of person who chased after beautiful girls, so I didn’t have any thoughts at the time.

Because of work, my sister-in-law and her boyfriend live in another place and only come back two or three times a year. And she usually comes back alone. Usually at this time, I discovered that my sister-in-law had a lot of suitors. Although she had a boyfriend, she would still contact those locally. Then she would keep calling and asking for countless dates, so I wouldn't see her every night.

According to my wife, those were all people who had pursued her or had a crush on her in the past. I can't help but sigh that finding a beautiful woman as a girlfriend is indeed not that easy, especially for someone as open-minded as my sister-in-law. Not to mention that she checks into a hotel with those men every night to chat and reminisce.

My wife and I have to rack our brains to help her cover up her lie when her boyfriend comes to check on her. One time I was chatting with my sister-in-law, and I asked her this question in a roundabout way. She seemed quite contented and said that her sexual desire was relatively high, and it would be best for her to have orgasm about three times a night. However, her boyfriend had injured himself a long time ago and could not satisfy her at all. My wife is a very reserved type. She had never even watched AV before she started dating me. But my sister-in-law is so awesome. According to her, she can't accept any kind of sex with men except anal. I am very excited about it.

Later she had a child and got married. She seemed to be quite content after marriage. Soon she gave birth to a daughter and stayed at home to raise the child. When my wife and I went to visit her, she was breastfeeding her baby. I took the opportunity to admire my sister-in-law's breasts openly.

To be honest, although my sister-in-law was slim, the only drawback was that her breasts were relatively flat. Normally, the breasts of thin people are not that big. I can't compare to my wife in this respect. My wife is much fuller than me. My sister-in-law, who is breastfeeding, has huge breasts. I didn’t expect that B cup could be upgraded to D cup all of a sudden. So I watched and fantasized in my mind, hoping that my wife would be bigger in the future. But the fact is that she was never able to surpass my sister-in-law's size.

Things change unpredictably. A year later, my sister-in-law and her brother-in-law had a family crisis because of gambling. Not long after, they divorced. So she became single again, left her child to her ex-husband, and returned to her hometown. It just so happened that there was an unoccupied room in our house, so she moved in.

And so the story of brother-in-law and sister-in-law began.

First of all, my wife is a nurse and we didn't have any children at the time, so when she went to work, I was basically alone with my sister-in-law. To be honest, at the beginning, I had the desire but not the courage to do it. I believe many people who have sisters-in-law are like this.

The problem is that my sister-in-law is more adaptable than me. Not long after, she changed clothes without closing the door and took off her pants directly when going to the toilet. Because the desktop computer is in her room, one time when my wife went to work and I was playing games (although the laptop also has a dedicated graphics card, it is not suitable for large-scale games), she suddenly said to me: "Brother-in-law, don't turn your head around, I need to get dressed."

I turned my head away deliberately and said, "I want to see it, what can you do about it?"

She looked at me and actually said, "It's up to you." She actually took off her pajamas and exposed her upper body.

Instead, I was shocked by her and said, "Hey, I am a man too, aren't you afraid that I will do something to you?"

She said, "It's nothing to take a look. It's not like you haven't seen it before, right?"

This made me speechless, because I saw that she said these words without blushing or feeling nervous. It really wasn't awkward at all. She also asked me, "Brother-in-law, how do you think I am recovering?"

To be honest, her figure has indeed recovered very well. Although her breasts are not as big as when she was breastfeeding, they are about C cup, almost the same size as my wife. Apart from a scar on her belly, there was no sign that she had given birth.

So the days passed one by one, and such scenes still happened frequently. From what I observed, she really treated me like a family member without any reservations. Three of us slept in one bed, and there were even cases where she and I shared one quilt. Occasionally I would take advantage of her, but she would just smile at me, which made me angry but helpless unless I really knocked her down.

Later she said to my wife, my brother-in-law is such a steady man, you are so lucky, sister, when I look for a husband in the future, I will definitely find someone who is as family-oriented as my brother-in-law. I thought to myself that you should just come to me directly and we can just live as a threesome. But in today's society, we can only think about this in our hearts.

Slowly, I felt the desire being squeezed out bit by bit, and I didn't know when I would be unable to control myself and do something.

In order to relieve my sexual desire, I secretly took her changed bra and panties and used them to redeem myself. After I was done, I quickly threw all the clothes into the washing machine and washed them quickly. The result of doing this was that I felt the fire in my heart become even stronger. By the way, she also praised me for being so diligent in doing housework that I even helped wash my sister-in-law's underwear. I am speechless again...

Finally one day, I bought the legendary "fly water" online. It is said to be very awesome and can turn a strong woman into a slut and so on. After receiving the goods anonymously, I made up my mind that I must win over my sister-in-law this time.

The opportunity came unexpectedly. My wife was on night shift that day and wouldn't be home until the next day. So I went to my sister-in-law's room again, turned on the computer and played games, but my mind was actually focused on how to get my sister-in-law to drink the holy water. At around ten o'clock, the decisive turning point came. My sister-in-law beat the landlord and said to me, "Brother-in-law! I'm hungry, help me get something to eat!"

My heart was pounding and I quickly agreed.

So I went to the kitchen, got a glass of milk, and poured the legendary colorless and tasteless holy water into it. I found some bread, fried an egg, cut some cucumber shreds, made a sandwich, and gave it to my sister-in-law.

My sister-in-law finished the midnight snack smoothly, and I sat in front of the computer nervously waiting for the aphrodisiac to take effect. After more than 10 minutes, the effect seemed to appear and my sister-in-law's breathing became a little faster.

His left hand was still pressing on her right breast. She screamed, and for a moment our eyes met. My mind moved, and I suddenly hugged her and kissed her on the mouth. The sister-in-law moaned softly: "Um...Brother-in-law, don't..."

But now I am in a dilemma and I will definitely not give up.

I took the opportunity to reach my hand into her pajamas and grabbed her breasts. I finally touched my sister-in-law's breasts! While I was sucking her saliva, I was rubbing her breasts and teasing her nipples. The effect of the fly spray seemed to take effect. She began to loosen her teeth and hugged me back.

So my tongue invaded further, found her small tongue and began to entwine it. Slowly she relaxed and began to respond to me, so I took the opportunity to ask, "Girl, how is it, are you comfortable?"

The sister-in-law was already a little confused at this time, and took the initiative to put her lips forward and said, "Brother-in-law, hug me..."

I began to rub her breasts vigorously, and put my other hand into her back and began to caress it. I kept kissing her cheeks, neck, earlobes, and began to nibble on her earlobes.

"Oh!..." The sister-in-law couldn't help but let out a seductive moan, and her nipples began to swell rapidly.

I took off her pajamas, and a pair of white breasts popped out. I threw her down on the bed and kicked her IBM notebook to the floor. I bit her nipple and started sucking, biting and licking it. My sister-in-law hugged my head and moaned loudly: "Brother-in-law, brother-in-law..."

I continued to kiss her waist, belly button, and even the caesarean section scar. At this time, my sister-in-law couldn't help but twist her body. I have to say that with a height of 165 cm and a weight of 95 catties, her figure is really good. She twisted her body like a beautiful snake.

As I kissed her down, I began to take off her pajamas and panties, so her most private parts were exposed in front of me.

I began to observe it carefully. Because she had given birth, her labia still looked a little enlarged compared to that of a young girl, but the color was still a very beautiful pink, which was definitely not like black fungus or Oreo. At this time, the little bean had already poked out and looked relatively moist. So I started to attack her vagina. I started by licking her clitoris. Her body fluids were lightly salty and a little bit fresh.

At this time she began to struggle and shouted, "Brother-in-law, don't!"

I asked, “Why not?”

She blushed and said, "It's dirty there..."

I couldn't help but laugh and said, "What's so dirty about it? Didn't your husband and your suitors lick you before?"

She said, "Well, they all say that I suck their dicks and they think it's dirty."

I was speechless. People nowadays don't know the joy of licking pussy. So I said, "What's dirty about it? Brother-in-law doesn't think so. They will help you lick me!" So I continued to concentrate on trying it out. At this time, my sister-in-law obediently let me spread her legs wide apart to facilitate my further attack on her private parts. Her moans gradually became louder and her pussy juice began to flow out slowly. I took advantage of the situation and stretched out a finger and began to insert it into her vagina.

My sister-in-law held my head, and I felt nervous. Would she still reject me even after all this?

Unexpectedly, she said shyly: "Brother-in-law, it's not fair for you to help me alone, let me suck you too!" I was stunned. I didn't expect that the first 69 position in my life would be completed with my sister-in-law. I quickly took off my clothes and pants and turned around. At this point we were finally naked facing each other. My sister-in-law held my cock, rubbed it a few times, and said, "Brother-in-law, your foreskin is a little long."

I said, "Yeah, it might be a little dirty inside, but I won't force you if you don't want to lick it." Of course, at this time I was extremely longing for my sister-in-law to give me a blowjob.

My sister-in-law smiled and said, "You don't mind that my private parts are dirty, so how could I mind yours?" Then she peeled off my foreskin and began to lick it carefully with her tongue.

When my sister-in-law finished licking and started to put the glans into her mouth, I couldn't help but feel comfortable. I finally let my sister-in-law give me a blowjob. It felt so good! So I continued to bury my head between her legs. My fingers felt the temperature of my sister-in-law's vagina, and my penis was sucked, licked, held and bitten by her mouth and tongue. My sister-in-law's oral skills are indeed much better than my wife's. Because my wife is very clean, she rarely helps me, and when she does, it's quite rigid.

In comparison, my sister-in-law is much more skilled. She can do almost all kinds of tricks except deep throat. When I inserted two fingers and began to touch her G-spot, my sister-in-law suddenly tensed up. I didn't expect that her G-spot was much more sensitive than her clitoris, which was the opposite of my wife.

So I rubbed the rough raised area even harder. My sister-in-law suddenly let go of my cock and moaned loudly: "Ah...ah...brother-in-law..."

The love juice gushed out like a spring. I turned over, hugged her, kissed her and started French kissing. When this long passionate kiss ended, my sister-in-law looked at me with watery eyes and whispered, "Brother-in-law, I want..."

I was moved. We have finally reached this point. This is the scene I have dreamed of for so long.

I gently laid her on the bed, spread her legs, and began to slowly enter her body. The warmth from the flesh channel almost made me unable to hold back and ejaculate. I quickly shook it gently a few times to allow for the adaptation process.

To be honest, my sister-in-law's pussy is not very tight, but it is not loose either.

There is a lot of vaginal fluid and the temperature is hot, which makes the penis feel like it is swimming in a soft sea of ​​flesh. I slowly went deeper, and the moans from my sister-in-law in my ears became more and more alluring.

Unlike the fake moans of Japanese actresses, real moans are actually more touching than those exaggerated ones.

I started to say sweet words to her: "Sister, you feel so good inside me."

My sister-in-law looked at me with seductive eyes and said, "Brother-in-law, is it me who is more comfortable or my sister?"

I told him the truth: "Your sister's is tighter than yours, but yours is more comfortable than your sister's."

The sister-in-law asked curiously, "Why is that? Don't you men like tight things?"

I couldn't explain it either, so I just said, "It doesn't matter if it's tight or not. If it's tight, just stick it in the asshole."

The sister-in-law blushed and said, "Brother-in-law, you are so bad. You can't even fuck me or my sister from behind."

I asked her why, and she said shyly, "We all have hemorrhoids, and they are quite serious."

I sweat...

I continued to move continuously, and we kissed and caressed each other while slowly increasing the pace of thrusting.

My sister-in-law's breathing slowly began to become heavier. She leaned over and whispered in my ear: "Brother-in-law, deeper..."

So I worked harder and spread her legs wider so that my cock could go deeper into her body. As I worked harder, my sister-in-law's waist twisted more and more. The only sound in the room was the obscene "pa" and "pa" sounds of our bodies colliding.

My sister-in-law's vagina became more and more muddy, and I started to sprint. My sister-in-law grabbed my hands and guided them to her lower back. And she actively put her tongue into my mouth.

I knew she was feeling it, and while tasting her saliva, I attacked the deepest part of her body harder and deeper. My sister-in-law could no longer stop her moans, her cheeks were red and her eyes were blurry. I felt that her flesh hole was becoming incredibly suctiony, so I also increased the frequency of entering and exiting.

"Girl, I'm about to come, do you want me to pull it out?" I asked.

"Don't... cum... cum inside..." I didn't expect my sister-in-law would let me cum inside her. I was extremely excited when I heard this and started to fuck her frantically. The obscene sounds from my sister-in-law's mouth became louder. With a burst of full force, I thrust my penis into the deepest part of my sister-in-law's vagina, and shot my semen into her uterus in waves. I finally defiled my sister-in-law's uterus! My sister-in-law hugged me tightly, trembling constantly, breathing heavily and occasionally uttering a few unclear words. This time the amount of semen was so large that I felt a blackout in front of my eyes, and then I collapsed on my sister-in-law's white breasts.

After a long time, I began to look for my sister-in-law's lips, but our breathing frequency was so rapid that I gave up continuing the oral entanglement. When I was about to get up, my sister-in-law hugged me and said, "Brother-in-law, don't leave, stay inside me."

Of course I wanted to keep it out. In fact, I fantasized about making my sister-in-law pregnant. That would be so cool.

By this time, my sister-in-law may have calmed down. Said: "Brother-in-law, let me ask you a question."

I started to feel a little nervous, so I just answered, "You go ahead."

My sister-in-law asked, "Did you give me something to eat?"

As expected, she found out, and I could only giggle. She rolled her eyes at me and said, "Men are really not good people. I thought you were a kind man, but I didn't expect you to be like this."

I had no choice but to launch a sweet offensive: "Who told you to be so beautiful and so attractive? I don't want to do this. But I really can't help but like you, so I resorted to this desperate measure... Sister, can you forgive me?"

My sister-in-law gently touched my lips and said, "Actually, I like you very much, brother-in-law. If it weren't for my sister, I might marry you! But I absolutely won't allow you to hurt my sister. So, I won't tell anyone about our affairs, and you have to keep it a secret, understand?"

I quickly agreed, thinking it couldn't be better. She continued, "Brother-in-law, sex is not an unforgivable thing for us adults. I have been out there for a long time and have seen a lot so I can accept it. But my sister is different. She has been working since she graduated and has never been exposed to these things. You can't hurt her, okay? Otherwise, I won't forgive you!"

While admiring the deep sisterly love between them, I solemnly promised her that I would never do anything to make her sister sad. Although what we are doing now is actually unacceptable to my wife, we agreed to keep it a secret.

At this time, the penis in my sister-in-law's body began to revive again, and my sister-in-law looked at me with a red face. So I started moving slowly again. That night, my sister-in-law and I had sex three times in total, tying the highest record in my life. Although I was exhausted by dawn, I still dragged myself back to my room to sleep.

When my wife came back the next day, my sister-in-law was smiling and didn't show any unnaturalness at all. I also marveled at my sister-in-law's amazing sexual ability. It seemed like nothing happened after a night of revelry. I had no choice but to tell my wife that I had insomnia last night, and I hugged her and slept until the afternoon before I recovered.

What happened afterwards was that my sister-in-law and I would secretly be affectionate whenever we had the chance. In fact, we had sex relatively rarely, but we hugged and kissed each other often. My sister-in-law has not remarried yet, but she has found a second boyfriend. It is said that she has amazing sexual ability, with the highest record of eight times in one night. I was embarrassed listening to this. The two are still working hard on their wedding house. I hope they can start their own family soon.

My sister-in-law still lives in my house when she is not working. Since she is a freelancer, she has more free time. Sometimes when my wife is at work and my second brother-in-law is also at work, I will have a secret affair with my sister-in-law. Maybe we will be sweet comrades like this for the rest of our lives.
