The story of artificial insemination of the sister-in-law (family incest adult novel)

My name is Akang, and people also call me Kangzai. I am 33 years old this year. By the end of the year, we had been married for exactly 10 years. My wife is the same age as me, and our child has just started elementary school. Our family is warm and happy. My sister-in-law is 6 years younger than us. She is 27 this year. The age gap is a little big, and we have always gotten along well in the past. But what happened during her artificial insemination some time ago is still fresh in my memory!

My sister-in-law Miroa got married when she was 23 years old. As a result, she had been married for three years until last year and still hadn't conceived a child. My parents-in-law were very anxious. My wife also asked me to bring back some special medicine when I went abroad, but it didn't work. Later, I asked my wife to secretly ask my sister-in-law if there was something wrong with my brother-in-law's sexual function. To be honest, when I asked her this question, I had some thoughts in my mind: objectively speaking, my sister-in-law is not as pretty as my wife, but after all, she is 6 years younger than us, very youthful, and she has a very fit body, which often makes people think of the feeling of being tight when touching her skin. If there is something wrong with my brother-in-law's penis, that would give me a great opportunity!

My sister-in-law and brother-in-law were the type who had a flash marriage, and they only started dating their boyfriend a few months before the marriage. So before she had a boyfriend, she often came to our house to play, especially in the summer when she was at her sister's house. She would be very casual, running around the house in my wife's nightgown, and obviously not wearing a bra, which always made my brothers secretly uncomfortable. In addition, the wooden door of our bathroom was nailed because a decorative thermometer was hung on it when it was first renovated. Later, the thermometer was removed, but the nail was pulled out, leaving a small hole through which you could see everything going on inside the bathroom. I quickly put up a photo of her favorite star before my wife noticed. This small hole had been the source of my pleasure many times when I peeped at my sister-in-law taking a bath. At first glance, my sister-in-law had the body of a girl, with small breasts but large, round and firm nipples. The hair down there was very thick, shaped like a trimmed Arabic numeral "1". Because the hole was too small and positioned too high, I never got a clear view of what she looked like down there. This kind of exciting voyeurism no longer existed after she got married... I once thought that since we lived in a big family and met each other often, I should be the first young man that my sister-in-law had contact with the most when she was still young and inexperienced. Would she have a good impression of me? But something that happened later made me shelve this idea: once she and her brother-in-law came to my house to play, I had just returned home and went into my bedroom to change into pajamas. I had just taken off my clothes and was only wearing small underwear. I don’t know why my sister-in-law came in without knocking to get her sister’s skin care oil. When she came in and saw me dressed like this, she couldn’t help but exclaimed, "It doesn’t matter, I’m not naked." She said indifferently, "Huh! Who cares!" and went out. In addition, in the summer, Miroa wears low-cut clothes. Whenever she bends down in front of me, she will naturally protect her chest with her hands for fear that her brother-in-law will see it, just like the subconscious actions of those strange women I see outside. From then on, I concluded that she treated me as just a brother, and I never expected anything more.

Later one weekend, my wife came back from her sister-in-law's house. Afraid that the children would hear, she secretly pulled me into the nanny's room and told me: She had asked her sister-in-law, and heard that although her brother-in-law was not very strong, he was a normal man and could have sex with his wife. Moreover, her sister-in-law had also been to the hospital, and there was nothing wrong with her body functions, such as fallopian tube obstruction or uterine adhesion. My wife asked me to think of a solution, otherwise her parents would be too worried. I had no choice but to follow the order and ask around. Later, I heard from a friend who worked in a hospital that although there was nothing wrong with a man having an erection and ejaculation, he would not be able to have children if the semen was not concentrated enough or if there were no live sperms in the ejaculated semen.

I told my wife the news. A few days later, my wife told me that my sister-in-law forced my brother-in-law to go for a check-up, and it turned out that the sperm was dead! The couple is planning to use artificial insemination. But my wife said she had an embarrassing request that she wanted me to agree to. She hoped that I could donate my sperm. Because my sister-in-law felt that although the sperm provided by the hospital was allegedly donated by healthy men with a bachelor's degree or above, she was afraid that if the man was too ugly, it would harm the next generation. Besides, my brother-in-law is so handsome, and my sister's child is so beautiful and smart. She feels that if she uses my sperm, the child will definitely have good genes, and will have a real blood relationship with them in the future. She just needs to not let her parents-in-law know, for fear that they will not be able to accept it due to their traditional ideas.

I said, wife, if you have no objection, of course I have no objection. Haha, I have another child! My wife said, "You are so beautiful! You are absolutely not allowed to tell the children in the future. This is because we want to protect the children's feelings. In addition, this is also the condition that my sister-in-law agreed to my brother-in-law. Early the next morning, my sister-in-law called me and said, "Thank you, brother. I finally convinced my sister yesterday, but I was afraid that you would disagree!" " "How could that be? I can go to any hospital today to collect sperm. "I answered." In Xiaofang's department. "Ah, Xiaofang." I really didn't expect to hear the name Xiaofang. Because Xiaofang is Miroa's classmate, and works in the obstetrics and gynecology department of a large hospital in our city. I once asked her husband to buy us a mobile phone and we had dinner together. "But how could sperm collection require me to go to the obstetrics and gynecology department? ...I asked my sister-in-law in surprise. "Brother...it's like this. This was suggested by Xiaofang. Since I chose someone close to me to donate sperm, I shouldn't use frozen semen as usual. That would cause some sperm to die and affect the pregnancy rate...You see, I'm embarrassed to say this..." Miroa explained hesitantly. "Well, okay, no problem." I thought to myself, it doesn't matter, I can't take advantage of my sister-in-law anyway, the sperm will just lack the step of being quick-frozen by liquid nitrogen. "Then please don't drink or smoke these days, okay? Just think of it as your future nephew, brother-in-law!" The sister-in-law seemed to be a lot more relaxed when she spoke. "It's no problem to quit drinking, but I really need to work hard to quit smoking." I thought to myself, this is not a nephew, this is obviously for my "son". "Thank you, brother-in-law. Let's go to Xiaofang's place together in two weeks." After hanging up the phone, I subconsciously put out the half-smoked cigarette.

A week later, my wife was on a business trip, so my sister-in-law and her husband and I went to the hospital. After entering the hospital, Xiaofang blocked her brother-in-law outside the door of Obstetrics and Gynecology Operating Room 3, and then my sister-in-law went into the operating room to prepare. I was led to an instrument room inside the operating room. Xiaofang told me that this place is different from the sperm collection room in the men's department of the hospital. There are no exciting videos to watch. I can only find a way to get the semen out and put it into a glass container she gave me. Xiaofang went out. I saw that it was a bit hot here, so I took off my pants completely, took out my baby, and told it: "You have to do your best today and give us some high-quality seeds." Then I started to stroke it slowly with my hand. Although he thought that his sister-in-law was right next to him and that she might not be wearing anything underneath, his little brother immediately raised his head high, but it was really boring to sing karaoke alone here. He had been masturbating for 10 minutes and still didn't feel like coming. "Squeak!" The door suddenly opened and Xiaofang quickly came in while I was still stroking my penis. My face turned red at that time and I covered my baby in embarrassment.

"What are you afraid of? Although I'm an obstetrician and gynecologist, I'm a doctor after all. I've seen everything. Brother Kang, come here, let me take a look. Can't it come out?" Xiaofang squatted down and grabbed my fully erect penis with her left hand, with greed in her eyes. To be honest, Xiaofang got married earlier than my sister-in-law, and she has some of the charm unique to a mature young woman. When MIROA and I invited her to dinner, I could see that she had a good impression of me, but I just had the desire but not the courage, and I never contacted her privately. I didn't expect that today my little brother would be held in her hand like this... My little brother was jumping disobediently.

"Brother Kang, I didn't expect your penis to be so big. It's really rare! But your foreskin seems to be a little long." Xiaofang stroked my penis back and forth with her hand while looking at me with an unusually tender look. "It's okay. The foreskin is only noticeable to be a little long when it's flaccid. You see, the foreskin falls back after erection. It won't affect the quality of your sex life, right?" To be honest, I didn't consider this a problem in the past. "Who said it doesn't matter? A slightly longer foreskin can also harbor dirt. Also, because the foreskin is usually covering the glans, the glans that is suddenly exposed during an erection cannot withstand the strong stimulation due to being suddenly exposed and will not be able to last long." Xiaofang was very professional when she said this. "Oh, to be honest, this is one of the reasons why I feel inferior to you. Although my penis is bigger than most men's, I usually ejaculate within 10 minutes of insertion. So this is the reason." "It's nothing. When you come back later, I can do a circumcision for you. It's just a minor operation." Xiaofang said, and then she carefully used a cotton swab dipped in some saline to help me wipe the coronal sulcus near the glans. Her face was getting closer and closer to my little brother. Just as Xiaofang's mouth was about to kiss my brother, the door creaked again, and my sister-in-law Miroa walked in unexpectedly. "Xiaofang, what are you doing?" asked the sister-in-law, seeming a little unhappy. Xiaofang subconsciously covered my penis with both hands, but her hands were too thin and could only cover my penis itself, leaving the entire scrotum completely exposed. My sister-in-law was staring at it intently, completely unlike the indifferent expression she had last time when she saw me changing clothes. This made me feel very uncomfortable, so I just grabbed the balled-up pants and covered my bare legs. "Oh, the conditions here are too unprofessional. Brother Kang can't ejaculate. I plan to stimulate the prostate through the rectum to help Brother Kang ejaculate." Xiaofang reacted quickly, and her calmness revealed my panic. "Xiaofang, I want to ask you, what will you use to put your brother-in-law's semen into my body?" My sister-in-law didn't seem very reassured about the operation, but her eyes were still staring fiercely at Xiaofang's hands covering my penis.

"We have a special sperm delivery device. Don't worry. We perform hundreds of artificial inseminations a year. We have experience and disinfection. There is no problem." Xiaofang was still squatting and didn't get up. "What is that instrument made of? Is it cold?" Miroa also squatted next to Xiaofang. Because she was wearing a surgical gown with a wide opening on her chest, I could clearly see that her cleavage was very deep. My little brother jumped up again disobediently and popped out from between Xiaofang's hands. Xiaofang quickly covered it with her hands again. "Well, it's made of alloy, but I can warm it up for you so it won't be too cold." "Xiaofang, I have a favor to ask you. I don't want that metal thing inserted into my body. I want a son. I heard that the chances of having a son are higher when a woman reaches orgasm. So let your brother-in-law help me put it directly into my body, but please don't tell Xiao Tao (my brother-in-law's name), okay? Brother-in-law, please, just think of it as your nephew!" The sister-in-law started to act coquettishly, and her right hand quickly touched my scrotum, and she gently rubbed my balls with her fingers. "We are brother and sister. How awkward it will be when we meet in the future if we do this?"

"Although I am willing in my heart, I still said this against my will." This is a special case and needs special treatment. If you don't say it, I won't say it, and Xiaofang doesn't say it, my sister won't know it either! Brother-in-law! "My sister-in-law's right hand has pushed Xiaofang's hands away and clenched my penis. My brother couldn't help but vibrate several times in a row."Okay, but we have to go to the operating table. The sanitary conditions here are not met! "Xiaofang took my penis back from my sister-in-law. I quickly found a step and stood up quickly, saying that it was too hot here. I took off my shirt and walked out of the door naked into the operating room.

My sister-in-law followed me out quickly, lay down on the bed, spread her legs and placed her white and tender legs on the leg support of the delivery bed. At this time, her entire vulva was exposed in front of me. Although I had peeked at her pubic hair before, this was the first time I saw her labia majora and labia minora, and so close. If I could have measured my blood pressure at that time, it would definitely have been over 180. Just think about it, I'm about to have sex with my sister-in-law whom I've been coveting for so long. Oh my God, am I dreaming? I carefully put my head in front of my sister-in-law's vagina and gently licked her labia minora with the tip of my tongue. She hummed, and then her body trembled a few times, opening her thighs wider. Her labia minora slowly split into a small crack, revealing the pink vaginal opening and a slightly erect clitoris. I used my fingers to completely separate her labia minora and licked her clitoris with the entire surface of my tongue. "Look how comfortable you are. I even want to have artificial insemination." Xiaofang walked up to me while wearing surgical rubber gloves and grabbed my penis with her hand and started stroking it. "Don't rub me to ejaculation, how can I fertilize Miroa later?" I was afraid that the stimulation would be too strong. If I ejaculated, the delicious taste that I haven't even enjoyed yet would be wasted. "It's okay. I'll help you press your perineum later, which will greatly delay the time of ejaculation. Besides, it's normal for you to ejaculate 10 minutes after insertion. Don't put a psychological burden on yourself, as it will only increase the time of sexual intercourse." Xiaofang said, rubbing her vagina with her other hand. My sister-in-law didn't say anything. She squinted her eyes and quietly enjoyed the blowjob given to her by her brother-in-law. After a while, his lower body was already wet. I thought it was almost time to insert it, but she sat up again, jumped off the operating table, pushed my butt to the edge of the operating table and asked me to lie down. Then she said: "Every time I see my sister's face looking so good, I am so envious. I think my brother-in-law must be very powerful. Look, you are so strong, but Xiao Tao is so thin. I thought that after we got married, I would urge him to exercise well and things would get better, but it didn't work. Brother-in-law! Your penis is so big, Xiao Tao's is only two-thirds of yours, and I can't even swallow your whole penis! Let me take a good look today." As the sister-in-law said this, she put my penis in her mouth as much as possible, and Xiaofang could only rub my balls beside her.

My sister-in-law licked the lower part of my glans urethra with the tip of her tongue at a very high frequency. I felt itchy and simply let them play with my penis. After a while I felt that the licking method was different, so I opened my eyes and saw that it was Xiaofang who was licking my penis. Her tongue was very soft and warm, which made me feel very comfortable. Xiaofang licked it a few times before her sister-in-law pushed her away. "It's me who needs to be fertilized, why are you enjoying yourself here?" The sister-in-law began to blame Xiaofang. Xiaofang said, "Look at you, you stingy guy. Is it easy to see such a big thing? Besides, I can use my saliva to disinfect you, hehe." My sister-in-law asked me to get up and said, "Brother-in-law, come in quickly. I can't stand it down there. It's so wet. Fuck me!" "Look at you, you little pervert. Why didn't I find it when I was at school?" Xiaofang said sourly. With a "pop", my penis completely penetrated my sister-in-law's vagina. It was indeed lubricated and it was such a pleasure to thrust back and forth! After twitching a few times, I suddenly thought that it had been such a long time and I still hadn't seen my sister-in-law's breasts, so I said coldly that it seemed that this twitching was not stimulating enough, and I felt like a robot! " "Then what kind of stimulation do you want? I'm ready to be penetrated by you all over, what else do you want? ”

The sister-in-law asked in confusion, and Xiaofang quickly unbuttoned her shirt, took off her bra and revealed a big pair of breasts. Her nipples were very long and stood upright. "Men also need visual stimulation when making love, which can help improve the quality of their orgasm." Xiaofang was like a teacher lecturing her sister-in-law, while rubbing her fat breasts with one hand and my scrotum with the other. "I don't need you to stimulate me, I have it too." My sister-in-law said as she opened her surgical gown, and a pair of exquisite breasts caught my eyes, wow! Her nipples were so pink and the goose bumps were clearly visible, so I quickly put my hands up and started to grab and rub them, constantly pulling her nipples with my fingers, and occasionally licking them wetly with my mouth. The sister-in-law couldn't help but scream, and Xiaofang quickly covered her mouth. "You'd better be quiet. You also asked me not to tell Xiao Tao. If you do that, Xiao Tao will get suspicious and rush in to see how you end up!!!" My sister-in-law was so scared that she quickly bit the corner of the untied surgical gown with her teeth, and continued to greet my thrusts with a frown.

It's strange to say, maybe it was Xiaofang's guidance, I lasted much longer today, changing 6 positions and thrusting for more than 20 minutes before ejaculating. Although it's not as good as some strong guys who can go for an hour or two, it's very satisfying for me, because my sister-in-law also reached orgasm several times in excitement. After ejaculating, Xiaofang asked me not to move and to keep my penis inside, so that the semen could be sent deep into her uterus. My sister-in-law had no strength left and closed her eyes as if she had fainted. I could only continue to hold her waist and wait for enough time before pulling out. At this time, Xiaofang put her nipple close to my mouth and motioned me to lick it. After about ten minutes, just when Xiaofang saw my brother raised his "head" again and was about to take off her pants, my brother-in-law shouted outside the operating room: "Xiaofang, are you okay? Why did the operation take so long?" My sister-in-law was startled awake, quickly sat up, kissed my erect penis reluctantly, put on the surgical gown, and lay on the mobile stretcher where she should lie after the operation, ready to be pushed out of the operating room. Xiaofang, on the other hand, tidied up her surgical gown with regret and said to her brother-in-law, "It will be over soon!"

In the following months, my wife and brother-in-law seemed to deliberately avoid us and did not let my sister-in-law and I meet alone. However, my sister-in-law's artificial insemination was successful, and she gave birth to a healthy and beautiful baby boy 10 months later. These days, she went back to her parents' home for confinement after giving birth. Sometimes when we were alone in a room, she was not afraid that my mother-in-law or my wife would come in at any time, and she deliberately exposed her breasts to feed the baby. I knew what this meant, but I was afraid that if I let it go on like this, my family would find out sooner or later, so I pretended not to realize it. Everyone, what do you think we should do?
