My Sex with My Sister-in-law (Family Incest Adult Novel)

My family runs a restaurant and also has rooms for guests to stay.

My adoptive mother was a widow, thirty-four years old, but she was plump and full of energy, and looked only thirty-five or thirty-six years old.

Anyone could see that her body was attractive and sexy, and such a body certainly needed an outlet, so she had more than two or three lovers.

I lived in the same room with my brother's wife, Lily. She was my brother's wife, and my brother was serving in the military. She was 24 years old.

I was seventeen years old at the time, and my adoptive mother and Lily treated me like a child.

One day, I went to the bathroom and when I reached the door, I heard a strange noise coming from the next room.

"Click, click..."

I walked over and looked through the window. I saw my foster mother's plump, snow-white body, naked and pressing against a man in his fifties, twisting her body constantly. Suddenly, I felt an unknown sense of fear.

"I saw something I shouldn't have seen..."

Panicked, I stood there not knowing what to do.

At this time, there was a quiet voice coming from the room...it was a man's. There was also the laughter of my foster mother and the atmosphere of people being active…

"ah………………"

This was my foster mother's sweet humming. My original intention to leave completely disappeared and I stood up to listen to the movement in the room.

“Ah… okay… okay…”

My foster mother's voice was so full of joy that I couldn't help swallowing.

I was excited and extremely curious about unfamiliar sexual behavior. I gently widened the window and stared into the room, although of course I didn't dare to breathe loudly.

The foster mother's sexy body was lying on her back with her legs spread to the left and right. The man's face was pressed on the woman's vulva. His hands were holding her high and raised breasts, while the foster mother was holding the man's cock, squinting her eyes comfortably, her chest rising and falling like waves.

The man's face was pressed on his foster mother's vulva, moving it up and down, left and right, licking the parted labia.

The foster mother's butt was twisting and her waist was swaying with it.

The man's breathing became more and more rapid, and his licking movements became more intense.

“Okay~~~~~~~Okay~~~~~~~~~~”

The foster mother made a sound of joy.

"You~~~~~~~~~suck harder~~~~~"

The foster mother even had difficulty speaking, so the man opened his mouth and took the entire vulva into his mouth.

“Ah~~~~~~~~Ah~~~~~~~~~~~~~~~”

The woman moaned loudly, and at the same time, she clamped the man's head between her legs, actively raised her buttocks, and let her flesh rub against the man's mouth.

My face flushed, blood rushed to my forehead, my cock was so erect that it was about to burst, and I unconsciously began to rub the erect penis.

While the man was licking the woman's vagina, he moved his thick penis towards the woman's mouth. The woman held the penis tightly, rubbed it with her hands for a while, then sucked it into her mouth, making a chirping sound.

The man suddenly fell sideways, and the woman pressed on him as if she was chasing him. His face was clamped between the woman, and the woman's butt was held tightly by the man.

The woman shook her buttocks and pressed her pussy against the man's face, moaning in ecstasy as the man licked her.

My breathing became rapid and almost difficult, and my chest heaved violently.

Just then I heard footsteps coming from the corridor. I stepped back hastily, but bumped into Sister Lily who was coming from the other end. My face flushed as if I had done something bad. I ran back to my room and got into bed. I felt my body burning, but Lily didn't come back for a long time.

Lily finally came back, stood at the door for a while, sighed deeply, then there was the sound of taking off clothes, and the sound of her going to bed, and then there was no sound. Soon, I secretly stuck my head out to see what my sister-in-law was doing.

She looked at me with wide eyes, and when our eyes met, we both quickly turned our heads away and covered our heads with the quilt.

I think she also saw what her adoptive mother did, and thought to herself how nice it would be if she could do that with her sister-in-law, so she had a hard time falling asleep.

I turned over gently and heard her sighing slightly. She seemed unable to sleep either. She was probably thinking the same thing as I was.

I clenched my cock, afraid that my sister-in-law who was sleeping next to me would notice, so I rubbed it secretly. My sister-in-law sighed again, covered her head with the quilt and went to sleep.

I don't know when I fell asleep, but suddenly I felt a stuffy and oppressive feeling. It was Sister Lily who entered my bed, hugged me tightly, and pressed something gentle against my mouth.

I asked nervously, "What's wrong with you?"

"Don't talk~~~~~~~~~I'm doing something very good for you~~~~~~~"

There were hot lips sucking on my lips again, and the strong body odor of the mature woman made me almost dizzy.

"Suck my lips too!"

My whole body was filled with wonderful impulses, and I hugged my sister-in-law's body like crazy.

My body trembled constantly when I smelled the strong scent of a woman.

From the thin layer of clothing separating her body, one could tell her heart was beating, which must have ignited an uncontrollable wild and greedy desire.

Ah~~~~~The sweet lips of the opposite sex that I dream about even in my dreams. This is the first time in my life that I have come into contact with the scent of a woman’s lips.

"Please put your tongue in my mouth~~~~~~~"

She murmured sweetly, and I sucked her red lips hard, then pushed the tip of my tongue hard into the woman's mouth full of wetness and saliva.

At this time, Lily's tongue wrapped around the tip of my tongue and sucked it. When I retracted the tip of my tongue, her tongue chased into my mouth.

I licked her tongue, and Lily trembled with joy. She entangled with my tongue more vigorously, pursuing incomparable pleasure, sucking each other's saliva mouth to mouth.

Lily pressed her hot, sexually-seeking body against mine, clamping me between her soft thighs.

My passion for sex can no longer be suppressed by reason.

I held Lily's body tightly with one hand and caressed her body with the other. With his fingers trembling with excitement, he gently pulled open the front of her dress, letting his fingers linger over the subtle curves of her waist and hips, relishing the feel of her flesh.

My rising desire made me touch the pubic hair and then move down. When I found the soft slit of the labia, the feeling of excitement almost made me unable to breathe.

It was the long-lack of man's caress, a hot sigh of hunger, the warm and wet feeling made my penis almost burst with excitement.

My fingers opened the mysterious door of Lily and inserted into the hot and soft vaginal flesh.

The vagina, which can drive a man crazy, reminds people of the flesh hole in the mouth of a cuttlefish~~~~~~~~~.

As the fingertips' caresses grew in intensity, Lily moved her inner wriggling desire to her thighs, lifted her legs to my chest, and then pressed on me, as if asking for more intense caresses.

I put her body on me, enjoying the pressure brought by the weight of the flesh. I hugged Lily's body with my left hand and lifted her butt with my right hand to appreciate the fleshy feeling there.

My fingers slid down along the groove between the two mounds of flesh and felt the wet crack.

Lily's vagina was now overflowing with love juice. I hugged her neck and concentrated all my attention on giving her a passionate kiss on the mound of flesh.

"Put it in~~~~~~~~~~"

I held the hot and hard cock with one hand and used the other hand to find her hole, wanting to insert it there, and Lily responded by falling down from above.

Because this was the first time, the penis thrust upwards from below two or three times, but it just slid past the hole and could not be inserted as desired…………..

"It's so frustrating!"

Lily suddenly said this, grabbing my cock with her fingers and twisting her butt towards the glans, trying to swallow it.

I also used force on my waist to push up from the bottom, and following the slippery feeling, I pushed apart the two pieces of flesh and inserted the penis deep into the flesh hole filled with vaginal fluid.

The deep part of the flesh hole seemed to have received the long-awaited cock, and it squirmed with joy.

Lily pressed the weight of her plump body on me, and hugged me tightly, sucking the cock deep into her hole and twisting her buttocks, and the soft flesh in the hole rubbed against the cock.

The two bodies attacked each other as if in war, causing their genitals to rub against each other.

Our breath was hot.

Lily suddenly whispered in my ear: "Come on top!"

After saying that, her body moved to the side, and my cock pitifully leaked out of the hole.

I wordlessly put my body between Lily's legs. Her plump white thighs swayed in the dark, and then she clamped my waist, and her vagina twitched impatiently.

I pushed hard on my buttocks and inserted it as if to pierce the uterus. Then I entered the hot flesh hole with a wet feeling.

"Don't move~~~~~~~~~~"

As she spoke, she pulled open her clothes in front of her chest, revealing her raised white breasts.

"Come and kiss my breasts."

I sucked and kissed, pressed and licked the top of her body, buried my face in the soft peak, and kept sucking and licking.

During this time, Lily was very active in working with my body, shaking her butt, rubbing the cock with the tender flesh of her vagina, breathing hot air, and slowly increasing the intensity of the movements.

The cock swelled in Lily's flesh hole, and she was so crazy about lust that a lot of vaginal fluid flowed out of her vagina.

Perhaps approaching climax, Lily asked in a hoarse and excited voice: "Fuck! Fuck!"

I fucked her harder and harder, rubbing against her flesh, and her body twisted and tangled like a giant snake.

Once every three times, I put my whole body weight on the penis and insert it to the root, as if I want to pierce the hole.

“Ah~~~~~~~~~~~”

Every time Lily moaned, raised her ass, and squeezed and rubbed my cock at the same time, my whole body became excited.

The paralyzing pleasure became more and more intense, the desire of the two people became more intense, and more vaginal fluid flowed out.

"You can't go out~~~~~~~~You can't pull it out~~~~~~~~~"

Because the vaginal fluid was too slippery, the penis accidentally fell out during thrusting, so she hurriedly grabbed it and stuffed it back into her vagina.

"Ah~~~~~~~~! Yes~~~~~~~~ dear~~~~~~ It feels so good~~~~~~~~~~~~~"

She moaned desperately, hugged my body tightly, spread her legs to the point of almost splitting, stretched her feet on the quilt and twitched restlessly, while her upper body leaned back and she whimpered.

" She is now experiencing the greatest joy of a woman and is going crazy with joy!! "

So I thrust harder, and a sizzling sound came out of the hole. Soon after on the glans

Feeling unusually stimulated, the pleasure grew bigger and bigger, then expanded, turning into indescribable joy~~~~~~

At this moment, I feel that sacrificing everything in exchange for such happiness is worth it, and I will never regret it~~~

"Oh! Ok~~~~ ok~~~~~~~"

Now there is only the pleasure of joy in front of me, and everything else no longer exists.

A hot feeling gushed out from deep within the body, along with a paralyzing intense pleasure, shooting from the base of the penis through the glans into the depths of the flesh hole.

I fell limply on Lily's body.

Lily also closed her eyes, her tired body completely relaxed, except for her rapid breathing.
