My wife is pregnant and uses her sister-in-law to cool her down (family incest adult novel)

I am a computer engineer, 33 years old.

My wife is about to give birth, but I am too busy at work to take care of her. Fortunately, my father-in-law and mother-in-law live very close to me.

Come to my house to help every day, sometimes stay in the guest room for a night if it's too late,

My wife Xiaoru has a younger sister named Yuqing, who is a freshman in college.

So in addition to my father-in-law and mother-in-law, my sister-in-law Yu Qing also often comes to my house to help take care of my wife's daily life.

I am 33 years old this year, and I never thought that I would be interested in a little girl.

I believe everyone knows who I am talking about. It’s my sister-in-law Yu Qing, who is fourteen years younger than me and only nineteen years old.

My wife and I have known each other for four years. Back then, Yuqing had just graduated from junior high school.

When my wife and I started dating, it was the sweetest time, but Yu Qing always liked to be a light bulb and follow his sister.

I felt really bad at the time, and I was quite repulsed by this sister-in-law.

Fortunately, Yu Qing was busy with schoolwork later on, and she no longer insisted on going out with her sister.

It left my wife and I enough space for just the two of us, and after three years of love, my wife and I walked down the aisle.

After marriage, my wife soon found out that she was pregnant. We both looked forward to the birth of this fruit of our love.

Although this child is the fruit of my wife and I's love, the appearance of this child has also brought about a qualitative change in the relationship between my wife and I.

The story I want to tell this time happened when my wife was nine months pregnant.

I still remember that period, the weather was very hot, and I watched the game alone in shorts at night.

My father-in-law and mother-in-law didn’t come to my house that day. After my sister-in-law Yu Qing slept with her sister, she went to take a shower.

After a while, I heard Yu Qing screaming from the bathroom. I didn't think too much and rushed into the bathroom to take a look.

Yu Qing sat naked on the floor, supporting herself with her hands in the bathtub as she struggled to stand up.

Yu Qing saw me coming in and said weakly: [Ah, brother-in-law, why did you come in?]

Seeing Yu Qing's naked body, I hurriedly apologized: [I'm sorry, I'm sorry, I didn't mean it]

Then I turned my back to Yu Qing and asked with concern: [What's wrong with you? Are you okay?]

Yu Qing: [I don’t know what happened, my leg cramped and I accidentally slipped and fell. ]

I had my back to Yu Qing, but I could tell from the faint sounds she made that she was in great pain. She tried to stand up, but fell back down.

Finally she spoke: [Brother-in-law, can you help me? Help me up.]

I asked her doubtfully: [You are completely naked, this doesn’t seem good...]

Yu Qing: [I covered it with a towel, you can turn your head]

I wanted to reach out and help her sit on the toilet, but she held a towel and clothes in each hand to cover her chest and lower body.

I didn't have any extra hands to support my weight, so I reached my hands to her armpits from behind, trying to lift her up.

But when I put my hand into her armpit from behind, Yu Qing: [Ah, so itchy...]

She twisted her body because she was ticklish, and the towel covering her chest fell to the ground.

I wanted to help her pick up the towel, but my eyes swept across her fair and plump body.

My eyes stayed on Yu Qing's fair breasts. As expected of a young girl, she was well maintained and had round and full breasts.

Yu Qing: [Ah, brother-in-law, help me pick it up], she temporarily protected her chest with her hands,

While picking up the towel, my hand accidentally slid across his delicate thigh.

A pair of long legs with white and tender feet and a slender waist made me react naturally.

I picked up the towel and gave it to her, and used the same method as before, asking her to endure the itch, and I helped her sit on the toilet from behind.

While helping her, it was the first time I touched Yu Qing's body. It was so smooth and soft, and her skin was very delicate.

I deliberately moved my fingers slightly forward to help her, so that my fingertips touched her breasts. The soft touch was so tempting that I couldn't stop.

It’s a pity that she is my sister-in-law, otherwise I would really like to execute her on the spot.

When she sat on the toilet lid, her legs opened unintentionally due to cramps, and the mysterious cave covered by the sparse black forest between her legs was faintly visible.

She leaned against the water tank with a painful expression on her face. I pretended to massage her calves, but then I caressed her.

[Are you still feeling bad?], I asked with concern.

I have played with several women in the past few years, but none of them can compare with Yu Qing.

Especially Yu Qing's appearance, she was pretty and delicate. I swallowed and thought, what a beauty she is, it must be a good thing for this girl's boyfriend.

Thinking of Yu Qing's current boyfriend's bloated and fat physique, it would be a waste of God's gift if he could often wreak havoc on this beautiful body.

I thought to myself: [If I could also...] Thinking of this, the reaction in my crotch became more and more intense.

But I was shocked. No matter what, she is still my sister-in-law.

If I do it to Yu Qing, it would be fine if she cooperates, but if Yu Qing resists and wakes up my wife, I will be asking for trouble.

I tried to calm myself down, but my penis was still standing up and making a big tent in my shorts.

I had to hide the changes in my body.

Yu Qing obviously didn't notice my physiological reaction.

Her eyes were slightly closed, her face full of pain, and she murmured in her cherry-like mouth: [My left leg is cramping, it hurts. ]

I hurriedly said: [Take a bath first, and then your brother-in-law will come to your room to massage you.]

After I finished speaking, I left the bathroom. If I stayed in the bathroom any longer, I was afraid that my animal instinct would take over and I would eat my sister-in-law.

When I walked out of the bathroom, Yu Qing's leg cramps had not yet subsided, and she was taking a shower alone.

When I got to the living room, I kept thinking about the scene just now, Yu Qing's lovely and charming appearance.

So I was alone in the living room, stroking my dick, and a thick stream of semen sprayed on the toilet paper.

This was the first time I masturbated while fantasizing about my sister-in-law.

Looking at the semen that had just been ejaculated, and seeing Yu Qing still in the bathroom, an idea came to my mind: why not tease Yu Qing?

Then I took out a paper bowl, mixed some herbal wine into it, added some mint paste, and stirred it evenly.

Of course, my special ointment was not finished yet. I picked up the toilet paper that was just stained with semen, scraped the semen off it and mixed it in.

My special semen paste for teasing my sister-in-law was finished, and Yu Qing had just finished her bath, so I took it into Yu Qing's room.

Me: [Yuqing, your brother-in-law will apply some ancestral secret recipe to help relax your muscles],

I was stirring the semen ointment in my hand, feeling very excited. I couldn't wait to smear my semen on Yu Qing's body.

I asked Yu Qing to take off her pajamas, and she shyly said: [Do I have to take them off? This is embarrassing.]

I coaxed her and said: [Just now in the bathroom you didn’t even have clothes on, now at least you have your underwear on, take it off, take it off]

I pretended to be calm and walked to Yu Qing, and spread her legs apart with my hands.

I squatted between Yu Qing's legs. Because the distance was too close, I could smell the fragrance she exhaled.

Especially the pair of big breasts that were trembling slightly due to breathing, less than ten centimeters in front of me.

I can hold those pink nipples in my mouth as long as I open my mouth, and I really want to hold these two pieces of flesh in my hands and rub them.

Heart troubled, the man could not resist the temptation.

Yuqing and I sat on the bed. I sat cross-legged and Yuqing sat beside me.

Then I lifted her left leg and put it on my leg, and I said: [It is easier to massage this way]

In fact, I wanted to feel the fit between Yu Qing's legs and my legs.

I never thought that there would be such a day when my sister-in-law and I would have close skin contact.

I applied some semen paste on her legs and stroked them back and forth.

Yu Qing: [Brother-in-law, what kind of ointment is this? It feels so cool and comfortable]

Seeing my semen smeared on my sister-in-law's legs, not only was I not scolded, but I was even praised by her behind her back. I became even more greedy.

Me: [If you like, I can give you massages often in the future. This ointment will also feel cool if applied all over the body. I will help you apply it later.]

Yu Qingtian really smiled: [Yeah, ok, thank you brother-in-law], at this moment her legs were already covered with my semen,

Seeing this, my cock couldn't help but jump a few times. I could feel that my cock had already been erected.

The veins on the penis bulged, like a sword waiting to be unsheathed.

Fortunately, I had already masturbated once with my hands just now, otherwise there was no reason for me not to fuck Yu Qing when I saw this situation.

===================================================

While I was massaging Yu Qing, I kept applying oil to her body. To be honest, I was quite nervous. I was too timid to do anything to her.

Just like that, it's getting late, so let's let go of the beautiful meat in front of me for the time being. There is another reason for this, which is to make her feel good about me.

I let her go so that she would think I was a gentleman and I would have a chance to rape her again in the future. I returned to the room with a feeling of excitement and a little disappointment.

That night, I tossed and turned all night, my mind was full of the image of my sister-in-law Yu Qing.

In my fantasy, I don't know how many times I fucked her. The next night, Yu Qing returned to her home.

My wife Xiaoru and I were the only ones left at home. We hadn't had sex for several months since Xiaoru became pregnant.

Whenever I feel sexual urges, she always asks me to do it myself. If I insist on having sex,

Xiaoru said: [For the sake of our child, just bear with it for a few months. I will accompany you after the child is born.]

We had had several arguments over sex, but the most Xiaoru would give in was to give me a blowjob.

That night, my penis was enjoying Xiao Ru's mouth, but in my heart I was thinking about her sister Yu Qing.

I watched Xiaoru giving me a blowjob. She had gained weight due to pregnancy and had a round belly.

Thinking back to the time when I gave Yu Qing a massage last night, her slender and attractive curves, I longed in my heart: [How great it would be if the person in front of me was Yu Qing]

As I thought about it, I pushed my cock towards my wife's throat and played deep throat. I kept imagining that it was her sister Yu Qing who was giving me a blowjob.

I thrust in and out so fast that my wife started to cough and cry.

Xiaoru: [Woo…husband…don’t be too forceful…woo…]

I closed my eyes and enjoyed it and said: [Honey, it feels so good, your tongue is so soft]

My wife also responded to me enthusiastically, but she didn't know that I was thinking about her sister.

My cock was in my wife's mouth, filling up her small mouth. Then I pushed hard into her throat.

My wife was immediately pushed to the point of coughing and tears streaming down her face. At this point I also ejaculated in excitement.

After it was over, everything returned to calm. The woman in front of me was still my wife, not my beautiful sister-in-law.

After a simple cleanup, I fell asleep hugging a pregnant woman. It seems that my sister-in-law and I can only live in fantasy.

===================================================

Ever since my last contact with Yu Qing, I have often thought about how to get my sister-in-law.

Finally, one weekend night, my sister-in-law came to my house alone.

The situation was the same as last time. I seized the opportunity and used the method I had planned to deal with her.

That day, after she accompanied my wife to sleep, I was alone in the living room watching a newly rented movie. Of course, this was the one I had chosen.

Seeing Yu Qing coming out, I motioned for her to sit down and watch with me. She sat on the sofa without any doubt.

I turned off the main light, leaving only the auxiliary light, and then walked over to sit next to her. I deliberately sat very close to her, so that our buttocks were almost touching.

In the dark night, I could only see Yu Qing's pair of sparkling eyes moving around, occasionally revealing her slightly nervous breathing, and she opened her mouth as if she wanted to say something but stopped.

I pretended not to know and focused on watching the movie playing on the screen.

It was a lingering love film, in which there were naturally many scenes of the hero and heroine making love in bed. Whenever such scenes appeared,

I slightly tilted my head to peek at Yu Qing's reaction. Her profile was very beautiful in the light and shadow, especially her erect breasts, which made her look even sexier.

She was staring at the naked male and female protagonists on the screen making love on the bed, her crystal clear eyes were covered with a layer of mist.

This is a sign that a woman is aroused.

At this time, I deliberately said: [It's so exciting. I haven't had sex with your sister like this for a long time.]

Yu Qing replied with a blush on her face: [Yes, yes, yes]

Seeing her reaction, I continued: [After your sister got pregnant, she refused to have sex with me.]

At this time, I put my hands on her shoulders and hugged her gently.

When I touched the soft skin of her arm, she was shocked.

In the shadows, I could see her face blushing and she was breathing nervously. The warm breath from her mouth sprayed on my face.

My penis is about to pop out of my pants.

Maybe the passionate scenes on the screen triggered her physiological reactions.

Yu Qing stood up: [Sorry! I went to the bathroom,,,]

She didn't finish her words. Maybe because of nervousness, she staggered and fell on me.

It was also a coincidence that the crotch of her soft buttocks just sat on my hard penis.

The soft and elastic buttocks fit tightly against my thick penis, which made my heart beat fast and my erect penis almost ejaculated.

She also felt the hard penis against her buttocks, her face flushed with shame, and she struggled to get up, rubbing her twisted buttocks against my big glans.

But it made me even more excited. I couldn't help but touch her thighs when she stood up. Her legs became weak again due to her nervousness and panic.

I fell down again, my lust was out of control, I forgot that she was my sister-in-law,

When she struggled to get up, I couldn't help but hold her thighs with my right hand and hold her erect breasts with my left hand directly through her suit coat.

Yu Qing said nervously: [Brother-in-law, what are you doing? Ah, let me go.]

I ignored her and continued to reach into her clothes and directly pulled her bra off.

Yu Qing was wearing a white lace bra. The material of the bra was a little transparent, and her nipples could be vaguely seen. It was really sexy.

I tore off her underwear, grabbed her white breasts and rubbed them non-stop.

I felt a warm sensation to my touch and I knew her nipples were hard.

She begged: [Please let go, we can't do this...]

I stroked her thigh with my hand and reached inside her thigh, deep into her already hot and wet vagina at the base of her leg.

She twisted her hips and struggled, reaching out to pull my hand that had entered her crotch, which only aroused my sexual desire even more.

She shouted: [Take your hand away, don’t do this, oops! ]

I pinched her beautiful breasts, and I touched her all over, making her feel helpless and arousing her primitive desire.

Because the hand I put between her legs was already wet with the vaginal fluid that seeped out of her panties.

At the same time, the thick penis in her buttocks kept thrusting upward, making her whole body go limp.

She said weakly: [Brother-in-law, let go, don’t do this...]

While she was talking, my hand between her legs had already slipped into her panties.

My fingers touched her labia, which was already slippery with her vaginal fluid. She opened and closed her thighs and begged me not to continue.

[I am your sister-in-law, I can’t… I can’t do this…]

I inserted my middle finger into her tender vagina, and felt the layers of tender flesh on the vaginal wall wriggling and contracting, tightly clamping my middle finger.

I used my middle finger to thrust rapidly in and out of her tender vagina, and my fingertips hit the clitoris deep in her womb, causing her vagina to open.

A stream of obscene fluid flowed out.

The strong stimulation made Yu Qing's body limp and she leaned against me as if she was paralyzed, gasping with her mouth open.

I took the opportunity to turn her body over, my middle finger was still pumping into her beautiful hole, and my mouth was pressed against her soft lips.

I put the tip of my tongue into her mouth and twisted it, sipping the sweet saliva in her mouth. The remaining trace of rationality made her not cooperate with my kiss.

She just closed her eyes and let me suck her soft tongue.

I supported her body and walked slowly into the room. She panted: [Brother-in-law, you can’t do this. You can’t do this to me...]

I comforted her: [I haven’t had sex with your sister for a long time, Yuqing, you should do your sister a favor and hold my heart so that I won’t go out and mess around]

Yu Qing struggled hard. I pinned her down on the bed, and she kept thrusting her hips and twisting her waist.

I rubbed my cheek against his chest, and the intoxicating scent of milk made me lose my mind.

So I quietly pulled down the zipper on my crotch with my free hand and pulled my shorts down to my knees along with my underwear.

The thick penis was raised over 90 degrees at this time, and a stream of crystal clear liquid was flowing out of the hard glans.

Yu Qing helplessly let me kiss and caress her until she felt me ​​pressing my thick penis against the fleshy buds on her labia.

She begged me with tearful eyes, [Brother-in-law, don't do this, stop it now], but at this time I pushed my hard big glans hard into her!

[ah! it hurts! ] Yu Qing suddenly grabbed my arm and screamed through gritted teeth,

Her whole body was shaking as if she had cramps, and instantly thick milky white vaginal fluid gushed out of her vagina, and she had her first orgasm.

After the climax, Yu Qing lay softly on the bed. While she closed her eyes and enjoyed the afterglow of the climax, I used my big glans to push aside her petals.

With the help of the slippery vaginal fluid, he thrust the entire thick penis into her vagina, which was made wet and slippery by the vaginal fluid.

Yu Qing felt a sudden swelling in her vagina and screamed in shock.

My big glans has stretched open her uterine cavity and pressed against her clitoris.

She struggled in panic and shouted: [No! it hurts! Brother-in-law, please pull it out,,,]

I hugged her tightly, blocked her screaming mouth with my tongue, held her hips with my hands, and thrust my penis hard into her tender vagina.

She struggled and screamed, kicking her beautiful legs. She shed tears: [Let me go! Let me go,,, don't do this,,,]

I ignored her refusal and used all my strength to violently ram her clitoris.

Me: [Ah, it feels better than fucking my sister, ah, ah, ah]

While she was grabbing my back, I used my hands to spread her snow-white, slender legs and placed them on my shoulders!

I kept thrusting, and the chains on her calves kept swinging!

I clearly saw my thick penis going in and out of her beautiful vagina, bringing out waves of vaginal fluid, and I was extremely excited.

At this time, tears flowed from Yu Qing's crystal clear eyes. I couldn't help feeling guilty. What was I doing?

The woman I was fucking was my wife’s sister!

Yu Qing, who was lying on the bed, just stared at me with her tearful eyes, her snow-white, gourd-shaped body motionless.

It felt like I was inserting an inflatable doll that had no reaction.

I looked at Yu Qing with guilt: [I’m sorry! You are so beautiful, I can't help it...]

As I was talking, I couldn't control my lower body, because the tender flesh on Yu Qing's vaginal wall seemed to have layers, wrapping around my penis layer by layer.

Every time I pull out my penis and then re-enter it, the tender flesh of the vaginal wall will automatically contract and wriggle.

The uterine cavity also tightly bit the neck groove of my glans, as if sucking my glans.

I didn't expect she had such a beautiful vagina, it's really the best among vaginas.

I plowed my sister-in-law's tender hole again and again, and my penis went in and out of her vagina.

Slowly, I felt that when my penis was about to leave her beautiful vagina, she hugged my hips with both hands.

My penis was inserted into her again and fit tightly into her beautiful vagina.

Women are really contradictory animals, so I stopped saying more and continued thrusting my penis into her beautiful vagina.

Then, Yu Qing closed her eyes, seeming to enjoy the pleasure of genital union, and I also felt the sucking of her exquisite vagina.

We just responded to each other silently.

My lips pressed against her soft lips. She opened her mouth and put her tender tongue into my mouth, letting me suck her sweet saliva.

Then she sucked the tip of my tongue into her mouth and entwined it with her tongue.

The vagina in her lower body began to rotate and thrust, while tightening and rubbing against my penis.

It's so beautiful that all the bones in my body are softened.

I knew she probably didn't have much experience in sex, but she seemed to be gifted. The extreme excitement made me pump my penis harder in her beautiful vagina.

I really envy her boyfriend for having a girlfriend who looks innocent but is a slut in bed.

Then, my sister-in-law suddenly hugged me tightly with her hands, her vagina rotated and thrust rapidly, and her legs tightly entangled around my waist.

Yu Qing began to moan: [Hmm, Hmm, Oh, Yi,]

Yu Qing: [Sister,,,brother-in-law,,,hmm,,hmm,,,brother-in-law,,,]

Seeing that Yu Qing was getting more and more aroused, I pretended to be stupid and asked her: [Do you want me to be more forceful? ]

Yu Qing responded shyly: [Yeah, okay]

Hearing my sister-in-law say this, my body's adrenaline secretion reached its peak, and I fucked Yu Qing madly.

While doing it, I asked her: "Is mine big?" Are you comfortable? ]

I excitedly thrust my penis to meet the friction of her vagina, and used all my strength to fuck her beautiful hole.

Her vagina suddenly began to contract rapidly and suck my penis, and the deep uterus also tightened and bit the neck groove of the big glans.

Our lower bodies had completely merged into one, and as her vagina was vigorously rotating and grinding, she had another orgasm.

Streams of thick and hot vaginal fluid spurted out from the clitoris and poured onto my glans penis. I could no longer hold back my fluids, and my glans penis felt numb and itchy.

Because she is my wife's sister. After playing with her, I can't let my sister-in-law get pregnant with my child.

After my big penis thrust hard into Yu Qing's beautiful pussy a few times, I wanted to pull it out and ejaculate.

I panted and said: [I want to cum outside, hurry up and leave]

But Yu Qing sat heavily on me. I wanted to push her away, but it was difficult to do so.

At the same time, I felt my sister-in-law's cervix contract violently, clamping the neck groove of my glans like a pair of pliers.

Her vagina was like a big suction cup, sucking my entire big penis tightly. My lower body was so tightly connected to hers that there was no gap at all.

I felt so comfortable that all 36,000 pores in my body opened up.

As the glans continued to feel numb and itchy, he thrust hard, and the tip of the glans was already pressing against Yu Qing's clitoris.

The glans and the small opening on the clitoris were tightly sucked together, and my hot milky white sperm spurted out and was all injected into her heart.

In this way, my sister-in-law's vagina was filled with my hot semen. She couldn't help but moan loudly and her whole body twitched again.

The continuous orgasms, one after another, paralyzed her whole body. She just closed her eyes and reveled in the pleasure of sexual intercourse.

The vagina under my crotch tightly bit my penis, contracting and sucking continuously, as if it wanted to swallow up every drop of my thick semen.

That day, we did it five times in total. Yu Qing was fucked so hard by me that she couldn't stand up at all.

I took out all the emotions that my wife had not allowed me to express on her sister Yu Qing.

I think a beautiful woman can indeed bring out the potential of men.

Facing such a beauty, I felt like I was back in my school days. I tried my best to show off my beauty to my sister-in-law.

Gradually, during my wife's pregnancy, I stopped asking her to have sex with me.

Because I saved all my energy to deal with her sister, Yu Qing.

However, in the past month or so of having sex with Yu Qing, she still refused to give me a blowjob. She always thought it was dirty.

Until one time, I coaxed her and said: [Your sister was willing to give me oral sex during her pregnancy, and she didn’t mind it being dirty, why don’t you try it too?]

Seeing my little brother in pain, I half-forced myself to grab Yu Qing's head and then pushed my penis into her mouth.

During the process, she was not as repulsive as I had imagined. I watched her suck my glans with all her might.

I thought to myself: [Today I must let my semen fill your little mouth]

I felt the pleasure brought by my sister-in-law giving me a blowjob. Yu Qing opened her red lips slightly and panted, looking like she was enjoying it.

I was stunned when I saw this pornographic picture. My penis head was sucked by her, and my genitals and my sister-in-law's tongue were intertwined.

Entangled like two mating snakes.

Suddenly, a stream of hot liquid gushed out of my body and poured into Yu Qing's mouth.

Yu Qing cried out: [Ah,,,]

Just as I relaxed with satisfaction, thinking that I had finally conquered my sister-in-law's mouth,

My sister-in-law actually climbed on top of me, and suddenly hugged my head and kissed me.

Instantly I felt that all my semen was spit back to me by Yu Qing.

I spit it out in disgust, me: [Ah, what are you doing?]

Yu Qing bit her lower lip and said to me: [What? Do you think it’s dirty? You don’t dare to eat your own semen?]

I was frightened by this sudden action.

Yu Qing said: [In the past, when someone asked me to give a blowjob, I would do this, hehe, did it scare you?]

I didn't expect my sister-in-law to be so naughty.

I think after this incident, I will never again dare to put my semen into their sisters' mouths.

My relationship with Yu Qing did not end with the birth of my child.

On the contrary, I often took advantage of the excuse that my wife couldn't go out because she was taking care of the kids, and took my sister-in-law to the hotel.

After all, my wife's figure is completely out of shape after giving birth, and only my young and beautiful sister-in-law Yu Qing can satisfy my sexual desire.
