My wife is having an affair with her younger brother (family incest adult novel)

My wife is called Xiaoyin. Although she is not very pretty, she is very sweet. Plus, she has a figure that would make any boy's eyes light up. She told me that it's 34D22 and 33. But I have no way of knowing whether it's true or not because we have never had sex. I'm not in a hurry because I really love and respect her.

Today she told me that her cousin would be coming here to play for two days this weekend. I said that since we have an empty room at home, why not ask him to come and stay with us for two days. My wife happily said yes loudly and then hurried to call her cousin. I guess they must have not seen each other for a long time, seeing how happy she is. Seeing her so happy made me very happy too, so I went out to buy some daily necessities for her cousin and then went to the supermarket to buy a lot of vegetables to cook a big meal for her cousin.

Her cousin arrived around five in the afternoon. Although he was only eighteen years old, four years younger than me, he was very handsome, well-mannered and polite. He was very courteous to me, and I really liked him. In the evening we celebrated the reunion of him and my wife after a long time. Of course we both drank some wine to cheer ourselves up. My wife usually doesn't drink, but she had several glasses tonight. We chatted and laughed until it was around 11 o'clock in the evening. I saw that he was very tired after just arriving, so I asked him to go to bed early. Then my wife and I went back to our room and went to sleep.

In my dream, I vaguely felt that my wife sleeping next to me seemed to wake up and walked out of the room. I thought she was going to the bathroom.

After a while, I heard my wife come back to the room, but she didn't go back to bed. Instead, she opened the drawer as if she was looking for something.

I ignored it. After my wife found the things, she gently closed the drawer and slowly walked towards me as if to see if I was still dreaming. After reading it, he opened the door carefully and went out with peace of mind.

I was woken up by the sound of my wife getting out of bed. I was about to go back to sleep but suddenly I felt like peeing so I got out of bed to pee. I opened the door carefully to avoid waking up my wife's cousin who was sleeping next door like my wife did. After closing the door, the whole living room became dark and only the hazy moonlight could be seen outside the window.

I was about to walk towards the bathroom when I suddenly noticed light coming from under the door of the room where my wife's cousin was sleeping. I wondered why my wife's cousin was still awake so late. When I listened more carefully, I could faintly hear voices coming from the room, but they were very soft. If I didn't listen carefully, I wouldn't be able to hear them. Not to mention that if I was still in the room, I would not be able to hear them at all. Out of curiosity, I slowly approached the door of the room where my wife's cousin was sleeping and put my ear outside to try to hear what he was saying inside. I thought he might be talking on the phone with his mistress. As I listened, I kept my eyes on the direction of the bathroom, worried that my wife would come out and ruin my good time.

There is sound.

"Sister Yin, I'm so sad that I can't sleep." It turned out that my wife was in her cousin's room. I thought my wife was in the bathroom.

"It's really hard to believe that you are still so naughty at this age. Look, I'm here to accompany you," I heard my wife say in a low voice.

"Sister Yin, I'm really sad. Can you help me? Just like you used to help me every night before going to bed." My wife's cousin said as if he was acting coquettishly.

But my wife's cousin was asking my wife to help him with something. I couldn't help but gently open the door a little and peek inside. I saw my wife's cousin lying on the bed in his pajamas and my wife was sleeping next to him. I was shocked and angry when I saw this and wanted to kick the door open, but I didn't.

Because I saw that although they were sleeping together, they didn't do anything excessive. Am I overthinking it? Maybe they were just chatting.

"I just wanted to help you relieve the stress of puberty. I didn't mean any other thing. Now that you even have a girlfriend, why are you still naughty and want me to help you? You should go drink a glass of cold water and go to bed early." The wife said to her cousin with squinted eyes. As she spoke, my wife was about to get up and get out of bed.

But her cousin was holding his wife's hand tightly.

"Do you want to ejaculate again tonight?" the wife sighed and smiled at her cousin.

Ejaculation... ejaculation what? I couldn't react for a moment, and my wife's cousin nodded gently. "I really can't persuade you, but you have to promise me to go to bed early after ejaculation. If you don't listen, I won't let you ejaculate in the future." My wife said lightly. As she said that, the wife lay down next to her cousin again. This time they were lying down. Because her cousin was also lying down, the wife was facing behind his cousin.

I saw my wife generously leaning her good figure against his cousin's back. Although there was a piece of pajamas between us, I could still see her cousin's satisfied expression. What shocked me even more was that my wife's right hand passed under her cousin's body and pulled up the hem of his pajamas, while her left hand was around her cousin's waist and gently pulled down his pajamas. His cousin was not wearing anything under his pants. A penis about six inches long was exposed. Lao Gao's penis had been erect for a long time, and a few drops of semen had even flowed out of his urethra. But not as thick as mine.

My wife's right hand was holding the ferocious penis, loosening and tightening it for several minutes before she began to stroke it gently. My wife kept stroking her cousin's penis gently, and it became higher and higher, with drops of semen constantly flowing out of the urethra of the penis.

At this time, my wife's cousin had an expression on his face that looked like he was in heaven and he kept moaning softly. My wife seemed to appreciate her cousin's moans and her hands kept coordinating with her cousin's moans to determine the depth of the stroking. My wife's right hand was not idle either, pulling her cousin's pajamas down lower and lower until they were taken off. Then she changed to caressing her cousin's two labia.

My wife moved her mouth to her cousin's ear and said, "This is more comfortable, right?" Then she moved her left leg between her cousin's legs and hooked her cousin's left leg and stretched it as far as possible. I saw that my wife's left hand was constantly stroking her cousin's penis while her right hand was around her cousin's waist caressing his crotch. The scene of her two pink legs spreading her cousin's legs apart was really obscene. The woman started to moan, not knowing whether it was to add to the fun or because she was really aroused. This made her cousin very happy. Her cousin's butt also shook along with it, so that the wife's hand could stroke his penis more vigorously. My wife looked at her cousin with sidelong eyes as if she wanted to tease him. The louder she moaned, the smaller the amplitude of her left hand when she stroked his penis. I saw her cousin shaking his butt desperately to get more pleasure, while my wife seemed to be unaware and was stroking him slowly as if at the beginning.

"Sister Yin..." her cousin asked.

"What?" the wife pretended to be confused.

"Put it on faster." Her cousin said while shaking his hips.

"Hurry up and put it on, is that right?" As my wife said this, she started to masturbate her cousin with her hand vigorously.

Her cousin could no longer answer and could only continue to moan. But at this time my wife's hand slowed down again. My wife moved her mouth to my cousin's ear and said, "Why are you stroking so fast? Do you want to ejaculate?" My wife was stroking it fast and slow.

"But it's very comfortable for me to hold your penis like this. If you ejaculate later, I won't have anything to hold." said my wife coquettishly.

"After you cum... I'll cum again." Her cousin answered with difficulty.

"Oh, I don't want to. Then I will become your sex toy for ejaculation. I don't agree." My wife said coquettishly again.

"So...what do you want to do~" his cousin asked with a mixed feeling.

"I want to ejaculate all the sperm in your cumbag at once. Then you'll feel great and I won't have to keep helping you ejaculate." said my wife with a blushing face.

"But what if so much sperm is ejaculated everywhere?" my wife said hesitantly.

"I know there is... a place that can completely hold... hold all the sperm I ejaculate," her cousin said again.

"Where is it?" asked my wife.

"You can take off your night...dress and then your panties and then... spread your legs and use your hands to open your labia. That way I can slowly insert my penis... this thick penis into your vagina to your uterus. When my glans touches your cervix I can spray all my sperm into you and then you will feel so good." Her cousin said lewdly.

"Put it deeper~" her cousin requested.

My wife complied with her cousin's request and stroked his penis vigorously a few times, then replied, "You're dreaming and actually wanting to ejaculate your sperm into my uterus and vagina. My vagina is not meant to hold your sperm." My wife refused and laughed.

"Whose sperm is that used for?" his cousin asked mischievously.

My wife continued to masturbate her cousin's penis with two shallow and one deep strokes, and replied with a red face and a smile, "It can be anyone's sperm, anyone can ejaculate as much as they want, but you can't ejaculate your sperm inside."

"Can I really not cum inside you? Really not?" her cousin asked innocently.

"That's right, you can't ejaculate inside. You can't ejaculate inside." said my wife proudly.

"That's great. Then I can only have sex with Sister Yin inside, but I can't ejaculate inside. Thank you, cousin." I didn't expect that her cousin was quite good at it and used words to frame my wife.

"You bad little pervert." My wife knew she had said something wrong and cursed softly with a blushing face. But my wife never breaks her promise in front of the younger generation.

"Sister Yin, you can't go back on your word now that you've promised." Her cousin said with a smile.

"I didn't agree to have sex with you. If you want sex, go ask your little wife. I only promised you to ejaculate your excess sperm every night to prevent you from having pressure during your puberty." said my wife gently.

"I know Sister Yin treats me the best. Every night I used to look forward to the moment when Sister Yin would help me ejaculate. But Sister Yin never goes back on her promise to me, just like tonight..." her cousin said with deep affection.

It seemed that my wife was also reminded of the happy memories of the past by her cousin.

"I don't know where you got so much sperm when you were so young. Sometimes you had to ejaculate several times a night before you could go to sleep. But later I found that as long as I got you very excited before ejaculation, you would ejaculate a lot of sperm and I would sleep well. The older you get, the longer it will take you to ejaculate. So I kept learning how to say some obscene words and use some techniques and gestures to make you ejaculate comfortably. From the time you were twelve to now when you are sixteen, I have almost become your personal sex toy for ejaculation." The wife happily recalled the past between her and her cousin.

My wife was still stroking her cousin's penis slowly, but the amplitude was gradually increasing.

"But ever since you, Sister Yin, got a boyfriend, we rarely sleep together. There's no one to share my worries and comfort me." Her cousin said pitifully.

"Come on, you just want me to jerk off your penis and ejaculate again." The wife was trying to divert her cousin's sad attention. "No, Sister Yin, I really missed you when you were not around." Her cousin had already started shedding a tear.

"I know, I know everything." The wife said quickly to comfort him, and at the same time she noticed that her cousin's penis began to soften.

"Look, you're so young, but it's gone soft before you even ejaculate. You're impotent." The wife wanted to draw her cousin's attention back to the happy things. She began to concentrate her firepower on attacking her cousin's penis.

"We haven't seen each other for such a long time, let your cousin see if your endurance has increased. Don't ejaculate so quickly. Your penis has become very scary and it makes my heart beat fast. Let me tell you, although you haven't seen your cousin's naked body, your cousin's boyfriend hasn't seen it either. He wants to see it and I won't let him succeed." The two cousins ​​hugged each other and laughed. I wanted to stop them, but when I heard that they had started this relationship before my wife met me, I couldn't say anything. What's more, they are cousins, so doing this is not incest. I put aside my jealousy and decided to share this bold and kind side of my wife with her cousin.

"Sister Yin, you didn't do that with your boyfriend..." her cousin asked guiltily.

"Of course not. Why do I suddenly feel shy? You want to ask if we have made love, right? He hasn't even seen my body. What's more, I have only helped him ejaculate about ten times during sex, and I didn't do anything special to please him. If he wants to ejaculate, he can. If not, I will go to sleep. But he respects me very much, unlike you who keep pestering me and letting you ejaculate again and again." said my wife sweetly.

"That cousin's husband is so pitiful." Her cousin said to me sympathetically.

"So you're still not knowing how lucky you are. Just enjoy your sperm." said my wife with a smile.

The two of them were slowly aroused by desire again. My wife even took off her cousin's pajamas. Now her cousin is naked and is caressed all over by my wife. They were all so focused on pleasing each other that they didn't notice me outside the door.

My wife began to hold her cousin's penis, which had swelled to 70% in size, with both hands and kept stroking it with great force. Their tongues sometimes intertwined. My wife kept moaning in her cousin's ear as if it was not her cousin who was caressing but herself.

The large movement caused my wife's nightgown to move up completely, and she didn't have any free hands to pull her pajamas down and tidy them up. My wife usually doesn’t wear a bra when she wears pajamas because she has big breasts and it would be uncomfortable to sleep with a bra on. Slowly the nightgown moved up to the point where the lower half of the breasts could be seen, but the wife continued to concentrate on holding her cousin's penis with both hands, stroking it constantly as if she was afraid that her cousin's enthusiasm would diminish.

My wife even playfully moaned in her cousin's ear, "My nightgown...ah~ My breasts are about to be exposed~"

Her cousin pretended to be kind and panted and asked, "Do you want me to help you pull down your nightgown...ah..."

"No, that won't work. You'll be touching my breasts like this. You're so bad. You just want to touch my breasts..." After saying that, my wife started stroking even harder.

The nightgown that had moved up hindered my wife's movements, so she stopped and took off the entire nightgown. When he lay down again, he was only wearing his underwear. My wife still put her right hand under her cousin's waist, but her left hand was around his waist again, tightly holding his swollen penis. The difference was that this time there was no nightgown blocking the way, and the two hot bodies were still tightly pressed together, while my wife's plump breasts and hard nipples were constantly rubbing her cousin's back in front of her.

"I haven't let you ejaculate for a long time. Today I'll let you ejaculate to your heart's content," said my wife with a blushing face.

"Do you feel it? I've taken off my nightgown. Today I'm going to rub your breasts, which even your cousin's husband has never seen. Your cousin's breasts are not small, are they?" my wife said with a blushing but proud face.

"My cousin really took off her nightgown. I said my cousin is the best to me and I never go back on my word, right?"

Her cousin moaned with enjoyment.

"What?" asked the wife puzzled.

"Have you forgotten that you said just now that you were worried that there would be no place for me to ejaculate? Sister Yin agreed to let me ejaculate in Sister Yin's vagina and uterus. Now Sister Yin is taking off your nightgown, then you just need to take off your underwear and spread your legs," her cousin said unwillingly.

In order to further stimulate my wife, her cousin's wife joined him in the crazy and lewd voice, "You want me to take off your underwear, spread your legs, and then hold your penis and slowly guide your glans to my vaginal opening, right? But your penis's urethra leaks too much lewd fluid, and my vaginal opening is also very wet. This way, your penis will be easy to insert."

"No, I'm just stroking your vaginal opening lightly. I won't insert it inside." Her cousin immediately defended himself when he heard that my wife was no longer so insistent.

My wife moaned loudly a few times at this time, as if she couldn't resist her cousin, and responded, "It's fine this way. Anyway, I've taken off my nightgown and my wet panties. It doesn't matter, right? My vagina is itchy too. My cousin's vaginal fluid keeps flowing out and the sheets are wet. It will be terrible if your cousin's husband sees it tomorrow. Can you please insert your penis into my vagina to stop the vaginal fluid from flowing out? Don't just stroke it shallowly, okay?"

My wife's cousin said desperately, "Please let me put it in, I beg you~" "Woo~"

My wife's right hand continued to stroke it vigorously and then slowly pulled the foreskin of her cousin's penis down, leaving only the red and purple glans. However, her left hand reached to her mouth and wet the palm of her hand with her tongue. Then she let her left hand return to her cousin's penis and kept stroking it back and forth several times, making her cousin's entire penis wet and hot.

"Let me prepare your big glans and big penis first, so it will feel wet and hot and comfortable," my wife asked lovingly.

"Ah~" "Ah~" "Ah~" "Cousin, let me put it in, I'm about to cum," my wife's cousin said loudly.

"No, you can only penetrate my cousin's vagina and you can't ejaculate inside her. Have you forgotten?" My wife saw that her goal was about to be achieved and answered in coordination with her cousin.

"Come, let me help you put on the condom. Otherwise, how can we have sex? Don't you want to help me plug my hole?" my girlfriend said gently. As I said that, my wife climbed up and took one of the condoms from the table next to the bed. So this is what my wife just came back to my room to get. When did she buy it? I didn't even know she bought two dozen. Did she buy so many just for it to help her cousin ejaculate? When my wife stood up, her naked body was exposed in front of her cousin and me. Her cousin and I were about to ejaculate in excitement. "Cousin, your breasts are so firm and beautiful. I can't help but ejaculate just by seeing you naked." Her cousin said excitedly.

"I'm not completely naked like this because I haven't even taken off my panties yet. Don't think about cumming yet, I have something to reward you." My wife held up her proud breasts with both hands, shook them gently, and smiled with a blushing face.

I saw her cousin's penis swelled so much that the blue roots were visible when he saw my wife deliberately seducing him, not to mention the swollen glans. My glans was the same.

"Watch out, cousin, let Sister Yin compensate your poor cousin's penis." After saying that, my wife put the condom in her mouth and put it on her cousin's penis. My wife continued to swallow her cousin's penis until the entire condom was put on. After putting on the condom, my wife continued to use her tongue to tease her cousin's swollen penis.

Her cousin seemed to be so comfortable that he forgot about inserting his penis into my wife's vagina and just kept moaning and shouting.

"Cousin, I'm going to cum." Before she finished speaking, her cousin started to ejaculate sperm everywhere.

My wife looked at her cousin with encouraging eyes, and then he sucked deeply for a few more times and then took over the job of her mouth with his hand and said, "Shoot, shoot hard, shoot more, and shoot your cousin to death." My wife looked at the tip of the penis covered with a condom with satisfaction as it continued to swell because of her cousin's continuous ejaculation. Both hands were still deeply stroking the excited penis that was ejaculating.

Suddenly, a few drops of semen spurted out from the top of the condom. It should be that the condom could not withstand the impact of her cousin's penis ejaculation, and the condom was torn into several small holes, and the semen spurted out.

My wife was startled at first, then she smiled at her cousin and took the ejaculating penis and the condom into her mouth. Watching my wife bending over and holding another man's penis in her mouth, her throat was gurgling as she swallowed all the semen that the man shot out of the condom. Her two round and firm breasts were proudly exposed to the air because of the gravity. I also began to ejaculate uncontrollably while holding the penis. It took her cousin about thirty seconds to ejaculate all the sperm. He is really much better than me. My wife also breathed a sigh of relief at this time, and her mouth left her cousin's penis and said, "Okay, the sperm has been ejaculated. Can we do it again?" After saying that, she laughed complacently.

"Cousin, you are so cunning. You agreed to let me in." Her cousin said angrily and weakly. "I didn't say I wouldn't let you in. It's you who are too useless, so you ejaculated like this. Let's talk about it next time when there is a chance." The wife pretended to be innocent.

"Really? You didn't lie to me." Her cousin was so abominable.

"Really, Sister Yin, I'm not lying to you. We are cousins. I don't mind having sex with you as long as you want to do it, and I enjoy it too. But the first penis to enter my vagina must be that of my beloved boyfriend, then my boyfriend will have nothing to say. Let your cousin do her job and then see if you are obedient, then I will consider letting your hateful penis enter my body." My wife said sweetly again.

"Then you should ask your cousin-in-law to insert his penis into your vagina and have sex with you." Her cousin said excitedly.

"Why are you meddling in other people's business? Your cousin's husband is not as lustful as you. Let's see what the situation is. If you can, you can stay for a few more days. For your sake, I have to take advantage of it and let your brother-in-law have sex with him early. But you are not allowed to peek at us. I will be shy. Is that okay? Go to bed, little pervert. Sister Yin is about to go back. Good night." My wife replied while kissing her cousin affectionately.

"Sister Yin, I can see that you love your cousin's husband very much. Stop pretending. You've been thinking about it for a long time, right? I guess your cousin's husband is not lustful, he just respects you too much. How about I give him a hint for you?" her cousin said considerately.

My wife just smiled in response.

My wife took off the condom that had been ejaculated on her cousin's penis, thought for a while, and then put the remaining condoms into the drawer of the small table in front of the bed. Then she got up and put on her nightgown. This gave the little devil another feast for the eyes.

Why did my wife leave the remaining condoms in her cousin's bedroom? Did they want to use them again? I thought that my wife would definitely step on my semen when she passed by here, but there was no time to clean it up. Hearing this, I hurried back to my bedroom.
