19-year-old sister-in-law and cousin-in-law (family incest adult novel)

I am 38 years old this year and I am fond of all kinds of sports, so I have maintained a very fit body and a handsome face. I have always been the object of girls' yearning. Although I have been married for ten years, my charm has not diminished. As long as I make a move, the young girls in the company and the mature women and wives who contact business can't escape the fate of moaning under my crotch.

However, recently I suddenly felt that wild flowers...are not as fragrant as domestic flowers... "Brother-in-law, you're back..." As soon as I walked into the house, I saw my sister-in-law Menglin coming out of the bathroom after taking a shower, wiping her long wet hair with a bath towel.

Menglin lives in our house because of her studies. "Yeah. Mengmeng, did you just take a shower?" "It's my birthday tomorrow, where's your gift?" Menglin said coquettishly. "Oh...Brother-in-law forgot." I spread my hands, "Then let's not celebrate it." "Woo...Brother-in-law doesn't love me at all. Parents and sister can't come back. Brother-in-law, you still..." Menglin's eyes were already a little wet. My father-in-law and mother-in-law went on their honeymoon these Tuesdays, and my wife went abroad to attend a seminar and will not be back until next week. "Ha... You're angry already! Look at this..." I took out a gift box wrapped in colorful paper from my backpack, "The latest model from NOKIA!" "Brother-in-law, you... are so bad..." Menglin jumped up.

"Ah! Stop it..." My sister-in-law threw me onto the sofa in the living room. "Who told you to be so bad..." Menglin burped at me in my arms. When no one was home, she and I would often play like this. After all, I had watched her grow up. "Ha... Mengmeng, stop... you..." I suddenly, "..." "What's the matter..." Menglin asked. She noticed something was wrong with my smile. I hugged my sister-in-law who was almost twenty years old and accidentally touched her chest. I felt her soft girlish body and her plump breasts. I also found that Menglin was not wearing a bra today. I turned over quickly and let my lovely sister-in-law lie on her back. I slipped down and knelt on the carpet beside her, leaning down and pressing my upper body against her bulging chest.

After taking a bath, the sister-in-law lay on the sofa, her cheeks rosy, her smooth white arms and slender round thighs were all exposed outside her bathrobe, like a lotus emerging from the water. I couldn't help it, so I bent down and kissed her rosy lips. My tongue tip flexibly pried open her two thin lips, probed into her tender mouth, and sucked the girl's small tongue. Menglin opened her eyes shyly, not knowing what to do, and let me suck and tease her.

It was the first time in her life that she was kissed by someone, and her mind was in a state of confusion and bewilderment. "Mengmeng, you are so sweet! Let me see you..." My mouth slid down the delicate and smooth neck and came to my sister-in-law's snow-white breasts. "Um... no, I'm your sister-in-law..." Menglin moaned shyly, "Let me go... what if someone finds out..." "There are only two of us at home, no one will see us." My hand slid onto my sister-in-law's perky breasts without leaving a trace, and my fingers deftly unbuttoned her bathrobe. Suddenly, Menglin's two round, elastic young breasts appeared in front of me. Even though she was lying on her back, her breasts were still pointed and erect. "Ah...Brother-in-law..." Menglin exclaimed, but it was too late. Her snow-white and plump breasts were exposed to the air, and her small pink nipples were trembling slightly. She clasped her hands across her chest shyly, trying to hide her slightly heaving breasts. "Mengmeng, don't be shy, you are really beautiful!" I pulled my sister-in-law's hand away, leaned over, took the pink areola on her plump breasts into my mouth, sucking and nibbling. "Well... you said you were just going to take a look, why are you doing this again... heh... don't... ah..." Menglin blushed.

My first kiss and my young body were both kissed and seen by my brother-in-law. How can I face people in the future? She was in a state of confusion. "What beautiful nipples!" I kissed the buds on the top of my sister-in-law's two round breasts in turn, making her gasp. "Well... we can't... Oh!... Oh..." Menglin struggled and twisted. If I hadn't held her slender waist, she would have slipped off the sofa. Menglin's skin is not only white and smooth, but also delicate and elastic. She exudes a faint fragrance of a young girl, which makes me burn with desire. I keep teasing her pointed and bright red nipples with the tip of my tongue. I felt that this kind of possession was not enough, so I reached out and pulled off my sister-in-law's bathrobe, revealing her delicate and exquisite girlish body. Her swollen, full, pointed breasts were smeared with my saliva, and swayed slightly with her rapid breathing. "Oh...brother-in-law...oh...um..." My lips moved to my sister-in-law's extremely sensitive abdomen, licking and kissing her round belly button, causing her to tremble.

Then, I quietly pulled down her lace panties, kissed the bushy pubic hair in her most mysterious triangle area, and breathed in her unique virgin fragrance. "Oh... don't do this... oh..." Menglin murmured incoherently from her little mouth, panting and moaning softly. I gently stroked my fingers in my sister-in-law's female secret valley, gently pressed my fingertips into the gap, rubbed up and down, clicked, pressed, and kneaded the slightly protruding flesh buds... In a moment, the flesh petals secreted a stream of warm honey, dripping on the inside of my sister-in-law's white thighs... I gently licked it with my tongue, and then, I held Menglin's plump and tender flesh lips in my mouth, and slowly stretched the tip of my tongue into her tightly closed petals to lick... The dew that continued to flow out of my sister-in-law's lower body wet my cheeks, and I sucked my sister-in-law's honey hard. "Um... let me go... ah... brother-in-law... please... oh... ah..." Menglin closed her beautiful eyes and couldn't help but moan loudly.

She felt waves of heat surging from her lower body, and her body twitched constantly. At this moment, I took off my clothes as quickly as possible, revealing my muscles which were quite strong for my age, and my most proud majestic cock. The hard rod was about sixteen centimeters long, with blue veins exposed, and it was tilted upward at 45 degrees. The glans was as big as a small egg, and was purple and shiny. Taking advantage of my sister-in-law's distracted mind, I lifted her round, white buttocks, placed the head of my penis in the virgin's secret part, found the entrance to the secret passage, adjusted the angle, and pushed it into her body! My sister-in-law's secret passage is so tight and narrow that it seems unable to accommodate the huge thing of a strong man like me. My glans is tightly clamped by the wet and hot tender flesh, and the top of the glans feels an obstruction in front... "It's so tight!" I was so excited that I took a breath and pushed forward hard.

Fortunately, after the caress just now, the secret passage has become quite lubricated. I held my sister-in-law's buttocks tightly and took advantage of the situation to advance forward... The hard glans forced open the soft and tender flesh wall of the secret passage, and the thick penis instantly entered the girl's forbidden area and broke through the bottleneck of the flesh membrane at the entrance! …I took my sister-in-law’s virginity! A tearing pain came from her lower body, and Menglin suddenly woke up from the numbness. "Ah!... It hurts..." Crystal tears flowed out... "Don't cry, Mengmeng, it will be fine in a while." Seeing my sister-in-law's pretty face twisted in pain, I restrained my excitement of losing my virginity and my animal instincts, and forced my swollen cock to remain motionless in my sister-in-law's tight vagina, carefully feeling the pulsation of the virgin's honey hole.

I kissed Menglin's trembling red lips, and gently stroked her perky breasts with my fingers, flicking the bright red, pointed nipples... After a while, I felt Menglin's lower body slowly relax. I wiped the tears from her face and asked, "Are you feeling better?" "Yeah, but it still hurts a little..." Menglin nodded shyly, tried to lift her buttocks, and felt that she had adapted to it a little. "Brother-in-law...you...be gentler..." I couldn't bear it anymore, and slowly pulled my cock out of my sister-in-law's tender pussy. While looking at her shy look, I once again pushed my iron-hard and strong penis deep into my sister-in-law's tight little pussy.

Start by moving it gently and softly. Menglin clamped her legs tightly around my waist, allowing me to go deeper. Her little mouth kept emitting seductive moans... "Um... um... huh... oh... huh..." Gradually, I increased the speed and force of my thrusts. The indescribable pleasure, transmitted to my nerve center by the cock deep inside my sister-in-law's vagina. "Oh... oh... it's so sour... oh..." Menglin raised her vagina desperately to meet my attack, moaning loudly.

So beautiful! Looking at the delicate body of the girl twisting her body with lust under my crotch, I couldn't help but thrust in and out wildly, pushing the whole thing in at once. Not only did the glans hit the soft flesh of the flower heart, but I also pressed it down and rubbed it at will. The tender and beautiful sister-in-law and the burly brother-in-law are very passionate and erotic. After more than ten minutes of passionate intercourse, I was panting, twisting and thrusting my lower body, using my hard cock to continuously cultivate my sister-in-law's beautiful body.

The junction of their genitals was wet and shiny, dripping with love juice, and constantly making the "slurping" sound of the male and female genitals interacting. "Heh...heh...oh...oh...oh!!!" The sister-in-law arched her body, raised her vagina desperately, raised her snow-white thighs stiffly high, then let them fall down dejectedly and collapsed. I just felt a large amount of vaginal fluid gushing out of my sister-in-law's pistil, and her vagina suddenly became smoother, and the labia muscles opened and closed, sucking my big cock.

It’s so beautiful! I thrust vigorously for another twenty or so times, and suddenly I felt an unusually itchy tingling sensation on the glans. I knew I was about to ejaculate, so I immediately pushed my penis deep into my sister-in-law's vagina, and the hot semen gushed out! ... After making love, Menglin opened her eyes and said coquettishly: "My feet are so numb... Brother-in-law... you are so bad..." Seeing her own naked and blushing body, Menglin couldn't help feeling ashamed of her response just now. "Mengmeng, I will fuck you well like this every day from now on." My hand gently stroked my sister-in-law's smooth back. "How can this be possible?" Menglin hesitated, "What should we do in the future?" She was thinking in panic: He and she are sister-in-law and brother-in-law, and it is impossible for them to become husband and wife just because of this intercourse, but her virginity has been taken away by him! "Don't think too much. Go to sleep. You have to go to school tomorrow." I picked up Menglin's beautiful body, walked into her bedroom, gently put her on the bed, then I got into the quilt and held her in my arms. Menglin, feeling completely confused, had no choice but to close her eyes and fell asleep on my chest.

The confused Menglin finally succumbed to the orgasmic pleasure I brought her and accepted the fact that she was possessed by me, her brother-in-law. During the week when my wife was away, I made love every day with my sister-in-law who was tasting the sweetness of sex for the first time. The living room, bedroom, bathroom, kitchen... even in the car when we took her to and from school, there were traces of our lovemaking everywhere... "Brother-in-law, help me rub my back." In the bathroom, I admired my sister-in-law's snow-white and jade-like back, which was covered with fine bubbles rubbed out by the shower gel, making her skin look more radiant. I couldn't help but praise her: "Mengmeng, your body is so smooth, let your brother-in-law hug you." As I said that, I touched her jade back with my hand, and it felt like silk. I couldn't help but kiss her neck. "Hmm..." Menglin touched and kissed me, feeling shy and loving, and couldn't help but let out a soft moan of ecstasy. Suddenly, she felt her brother-in-law's palms on both sides of her armpits, and his fingers gently tickled her. She couldn't bear it, and she shrank her body with a "hih". I took this opportunity, reached forward with both hands, hugged my sister-in-law from behind, held her breasts in my hands, and rubbed my erect penis in her butt crack. "Ah! Brother-in-law..." The sister-in-law trembled and wanted to say no, but her two pink nipples were pinched by my fingers, and her tender little butt felt the pressure of my hot and hard cock. The pleasure made her breathless, so how could she make a sound! I smiled and said, "Mengmeng's breasts are so smooth and full, no matter how much I touch them, it's not enough, let your brother-in-law rub them again!" I pinched her nipples, and then covered her two beautiful breasts with both hands, rubbing and kneading them, making my sister-in-law moan continuously. After a round of playing with me, Menglin's whole body was soft. Every time I pinched her little nipples, her body trembled. I think her little pussy must have become itchy.

I rubbed her breasts with one hand and picked up the shower head with the other, spraying it on my sister-in-law's exposed thighs from the front. "Ah! No..." The cold stream of water hit the sister-in-law's sensitive lower body, causing her whole body to tremble violently and she cried out. My hands let go of my sister-in-law's beautiful breasts and quickly moved to her crotch. The touch of her wet pubic hair was so wonderful! I pressed my fingers on the two labia, rubbed them a few times, then I parted the two labia and inserted a finger straight in.

As soon as the finger entered the vagina, it was immediately surrounded by a tight force. "Ah! Brother-in-law...Oh..." The sister-in-law's body was also wet, but it was completely different from the shower water, it was sticky and hot, and the flesh inside seemed to be about to melt. The cold water from the showerhead continued to hit Menglin's delicate vagina. I inserted my fingers into her vagina and began to stir it, while my thumb rubbed her hardened clitoris. "Oh... so comfortable..." My sister-in-law leaned on the wall with her hands. I made her feel comfortable and uncomfortable all over. The deep part of her pussy kept contracting, like an ant crawling, and it was extremely itchy. My cock stuck in the crack of my sister-in-law's ass had expanded to its limit. I threw the shower head aside, pulled my sister-in-law's ass back and up with both hands, did a half squat, and then pushed up hard. The whole swollen and hard cock penetrated into my sister-in-law's warm, moist and tender pussy! "Ah!" My sister-in-law grabbed the wall with her hands. My big cock brought her a full pleasure, making her tremble all over.

I didn't give Menglin any time to catch her breath. I grabbed her slender waist, pulled out the penis a little, and then thrust it all the way in deep between her legs until the base of the penis was pressed tightly against her labia that was stretched open by the thick penis. "Ah~!" This insertion made her lose her voice and she let out a long, trembling cry. The girl's pussy, which had been developed for several days, needed strong penetration. I started to use the thick and hard meat pole from below, pushing it up into my sister-in-law's warm and moist little pussy again and again. Her plump buttocks trembled and shook as they collided with my lower abdomen, and she was also pushed forward by my impact from behind. She kept moaning, "...ah...ah...brother-in-law...oh...so thick...ah..." As I was thrusting inside my sister-in-law, I watched her swaying back and forth due to the impact from behind, her buttocks and breasts shaking lewdly. "My dear Mengmeng, your little pussy is so tight! Oh..." My sister-in-law's young and tender body is so intoxicating! My cock was tightly wrapped in her small tender pussy, which was warm, soft and tight. More and more love juice began to flow out. My hard cock penetrated deeply into and pulled out from between her round tender ass, faster and harder, making a "puff, puff" sound. The juice brought out of the small hole when the cock was fucking wet the base of her spread legs... As the cock hit and penetrated from behind her ass again and again, my sister-in-law was pressed against the wall by the impact, and her whole body was lifted up from the base of her legs, moving upward from bottom to top.

The two soft breasts on her chest were pressed against the wall, rubbing up and down. As the thick penis twitched in her vagina between her legs, trembling and vague moans came out of her little mouth. “Oh…Brother-in-law…Oh oh…fuck me…” Menglin’s cheeks and body gradually turned pink, her lips opened and she gasped loudly, and she moaned “ah…ah…ah…ah…” faster and faster. After a while, she suddenly shouted with a trembling voice: "Ah~ I can't take it anymore~ It's coming~ Ah~ Ah~" Then the muscles in her two standing thighs began to tremble violently.

I was pressing down on Menglin's shoulders, and my cock was hitting the deep of her pussy hard. At this moment, I felt her soft and moist vagina wrapped around the cock suddenly began to twitch, and she let out a long, trembling moan from her mouth, "Ah~~~~~~!"
