Gentle Rope (Student Campus Adult Novel)

My sister was a sophomore in high school and was selected by a famous modeling agency after graduation.
As a model actor.

She is very busy with her work, and sometimes she even performs on stage in a swimsuit. Speaking of her figure, she is the most beautiful among all the women. She is 165 cm tall, with a bust of 86 cm, a waist of 59 cm, and a hip of 85 cm. Her body is well-proportioned, and her face is a typical Japanese image.
I know her skin is very delicate.

I am so lucky to have such a beautiful sister. Looking at the men around my sister, I can't help but feel jealous. So I thought of a way to get such a beautiful sister, no matter how hard I work.

My plan was simple. I wanted my sister to see me masturbating, and masturbating behind her ass.

Today, I am going to realize my idea. I walked behind my sister and saw that she was busy and didn't notice me. I deliberately walked closer to her and smelled her unique body fragrance. Her skin exuded the scent of a mature woman's perfume, and this perfume was particularly fragrant, which made me extremely excited.

I was ready to masturbate in front of my sister. I took my cock out of my pants and fiddled with it with one hand. Stimulated by the sight of my sister's beautiful body and the fantasy of having sex with her,
Soon my cock became hard, and I faced her from behind and played with my cock with my hand.

When my sister got excited, she looked back and saw me masturbating behind her, and her face immediately turned red.
Her heart was pounding, her breathing was rapid, and she turned around embarrassedly and hurried back to her room.

It is summer now, and I began to feel that using this method to stimulate her would definitely succeed, because my sister didn't scold me or beat me, which made me bolder to do this.

This went on for a few days and my sister didn't say anything. Finally, one day at two o'clock in the morning, I suddenly heard a noise in the living room while I was sleeping. I thought it was a thief coming in! Unexpectedly. ． ． I quietly opened the door and went out to see that the lights in the living room illuminated the room very brightly. When I saw my sister walking naked from the living room to the bathroom, I was stunned, my eyes were wide open, and my mouth was drooling. Soon I came to my senses. In order to avoid being seen by my sister, I quietly walked into the room and left the door ajar.
Took a long breath.

Under the light, I saw my sister's naked outline for the first time. Her hair was black, and her skin was so white and tender that I had never seen it before.

As I was thinking, I concluded that my sister was already taking a shower, and my parents were traveling and would not be back until the day after tomorrow, so I plucked up my courage and secretly walked to the other end of the bathroom. There was a transparent window that allowed me to see the entire bathroom, so I climbed to the window and looked into the bathroom. Puffs of steam rushed towards me, making me feel foggy. After a while, when the steam was not so much, I clearly saw my sister lying in the basin, constantly changing her posture, with one leg raised. Her white and well-proportioned thighs were really unbearable. At the same time, I saw a patch of black pubic hair, and I really wanted to pounce on her and fuck her right away.

I closed my eyes and thought: "Ah! Women, why are you so attractive? She is washing her own pussy and hair, oh! My heart is about to jump out of my chest. 』

Just then I heard my sister utter "ah" in a low voice, so I immediately looked at her, and my sister was also looking at me. I felt guilty and jumped out of the window immediately. I thought I was in trouble! !

At that time, my sister was hurriedly shaking her wet hair and stood up, wanting to leave this place.

I walked gently into the living room where she was undressing. My heart was beating like a clock. I was afraid that my sister would be unhappy and blame me. I didn't dare to breathe and stood motionless in the living room.
But at this moment, a strange idea suddenly came to my mind, and I became a little bolder.
So I took off the clothes I was wearing, walked naked to the bathroom door, pushed it open and walked in.

"ah. ． ． What are you doing! "The sister, who was still in the bathroom, saw her brother walk in naked, and was frightened when she saw something long and big on the root of her thighs. She quickly covered her chest with a bath towel.

"Why are you like that?" younger brother! How impolite! ! I was taking a shower and you were peeking through the window.
Now you come running in without clothes again! ! "The elder sister said this in a relatively gentle tone, and it was obvious that she did not express strong dissatisfaction with her brother's behavior.

When I heard my sister say that and saw her face blushing, I knew she didn't have any particular aversion to me.

"Sister, look?" You were showering late at night and I thought you were a thief. I came to the bathroom to see who was here? Finally I saw you taking a bath! Look, you've made my lower body wet. "I said this bravely, mainly to test my sister's reaction.

My sister suddenly turned around, facing my back, with her thighs tightly closed and her waist twisted.

And I was still the same as before, holding the head of my cock with one hand and hugging my sister tightly from behind, rubbing my cock up and down on my sister's ass, inserting the head of my cock up and down along her ass crack, circling her nipple with a finger and inserting my cock into her asshole, holding my sister's snow-white, plump, and big ass with both hands, although I didn't insert it, it made me feel flesh to flesh with my sister, which was very comfortable.

"Oh, that's too casual. What are you doing? 'Because I hugged my sister's body tightly,
She couldn't resist.
Can scream in the bathroom.

The head of my cock pressed against my sister's warm and soft buttocks, which immediately gave me a strong desire and I wanted to put my cock in her right away.

"oh! Sister, do you know? When I see your beautiful body and smell your body fragrance every day, no matter what the environment is, my sexual desire will rise rapidly. And every day I will masturbate while fantasizing about having sex with my sister. I keep stroking my cock several times a day, oh! elder sister. 'I'm a little confused and lost.

So, I used my hands to pull down the bath towel that my sister was holding tightly in her hands.

"No, that kind of thing." ． Too casual. ． ． "My sister moved her body hard and shouted.

"I will never let you go, sister! ! 'I hardened my heart and pulled her naked body hard to prevent her from leaving.

I held my sister's hand and said to her, "Sister, can you play with me? No one will know, absolutely no one will know. Dad and Mom are also traveling, so no one can take care of us. 』

"No." ． ． ． ． 』

My body was very heavy, and I pushed my sister to the ground. I put her hands on the ground to support her body, and used my hands to spread her thighs apart. I touched her vagina with my hands, making her whole body wet, and a fragrance came out of her.

"oh! elder sister. ． ． "I pressed my sister down with the weight of my body. I rubbed her breasts with one hand and used the fingertips of the other hand to open her vagina and look at it.

My sister continued to support her body with both hands, squeezing her buttocks and vagina hard.

Because I hurt her when I stimulated her vagina with my fingertips, which made her very unhappy:
"Ah, no!" don't want. ． ． 'Still resisting slightly.

I quickly used my fingertips to open her hole, and then I used my mouth to suck it while gently biting the tender flesh inside the hole with my teeth.

I was very anxious, so I used my middle finger, which I felt was longer, so I inserted it into her vagina at once. I was afraid that it was not deep enough, so I pushed it in hard. I thought the deeper it was inserted, the more satisfied my sister would feel, and she wished she could put her whole hand in there.

"Oh, ahhh." ． ． "I think my sister started to feel comfortable, so she gradually stopped resisting.

My sister's vagina was secreting water, but the water was different from the shower water. It was sticky and hot, and my sister was gasping for air at this time.

Suddenly I felt that I could play with such a beautiful woman, play with such big tits, lick her pussy, and rub her big, white, trembling ass. My flesh immediately felt numb.
I feel an indescribable itchiness all over my body.

I started by inserting one finger into her vagina, but I didn't feel it hurt that much. I wouldn't be satisfied if it didn't hurt me, so I suddenly inserted two fingers. After that, I started to pull up and down, faster and faster. The faster I pulled, the more juice came out of my sister's vagina. Her juice wet her pubic hair and flowed down her vagina to her buttocks.

Inserting fingers back and forth in the hole, separating the two labia, and using fingers to move horizontally downwards, makes my sister feel so good!

I used the flesh on my sister's ass, closed my eyes, held my cock in one hand, and continued to play with her pussy with the other hand. Such a scene is really rare.

My sister felt that I was no longer using my fingers to play with her pussy, so she took her hands off the ground, but did not change her original position. Because she could not see my hand movements, she touched my hands and put her head back on my shoulders.

"oh! I am so lucky, it feels like a dream. "I said to my sister excitedly.

Tens of thousands or even hundreds of thousands of men have seen my sister's well-proportioned and beautiful body in a swimsuit, but no man could strip her naked and play with her. And now I am the only one who has such great luck, and I am the first one to possess my sister. In the past, I even dreamed about such a thing, but my dream has come true.

"Ah, ah, ahhh." ． ． "The moaning sound became louder and louder. In an instant, my sister's whole body was shaking. Her flesh contracted tightly and she held her breath.

"What's wrong, sister?" "I asked hurriedly.

Suddenly, I saw my sister's butt crack shrinking tightly, and then white liquid flowed out of her butt hole! !

Watching my sister reach her climax, I couldn't help but smile with joy.

Since the day when I had an affair with my elder sister, she confessed her love to me. After that, I was often with my elder sister, and we felt very close to each other. Neither of us wanted to tell anyone about the affair between my elder sister and me. We both wanted to keep it a secret forever, and I knew that my elder sister had fallen in love with me now.

A few days later, because a woman's heart is always complicated, and it is impossible for me to know what my sister is thinking, when I went to find her that day, I saw an expression of opposition on her face, and I didn't understand why my sister was like this. When I asked to have sex with her, she drove me out of the room. After this, my sister changed. She hasn't talked to me for two or three days. There is always sadness on my face, and she always wants to avoid me. I feel puzzled. For the sake of the future (I only had sex with my sister once, and we have been cultivating our feelings in the following days), I didn't go to find my sister.

From then on, at 11 o'clock on the night of the fifth day, my sister must have been thinking about something and couldn't fall asleep, because the light in her room was still on.

"Brother, can you come to my room for a moment? 'My sister called from outside the door.

I quickly agreed: "Sister! Yes, sure. 'While opening the door and listening, he organized the reference books on the table.

Quickly, after tidying up my desk and homework, I went straight to my sister's room.

"I'm going to wear a swimsuit for a photo shoot tomorrow. I'm wearing a white one. The swimsuit is very thin and tight, and the black edges don't allow me to wear lining clothes with it, so I'd like you to help me shave my pubic hair. How about that?" "My sister said to me with a smile.

"Sister, I believe in you. You can definitely do it. I'll get the knife and shave you right away." "I said happily and immediately went to the bathroom to find a razor.

My sister was lying naked on her bed, her two big breasts were trembling, and a large patch of black pubic hair was exposed on the skin of her pubic region.

When I brought the knife, she covered her face with her hands out of embarrassment. When I saw my sister in this posture, my saliva suddenly flowed out and I could hardly move.

"I got it!" 'Then he knelt in front of his sister's pussy and started shaving.

But my hands were shaking with excitement. My sister's pubic hair felt very soft because it was very thin. So, I took a deep breath to calm my excitement and started to shave her hair. Soon, I had shaved all her hair off.

"Sister, I've finished shaving, what's next? 』

Seeing my sister's naked body still exposed in front of my eyes, looking at me with affectionate eyes, she did not stand up because of shaving her hair, nor did she answer my questions. At this moment, I could no longer bear the fire of sexual desire. I quickly took off my clothes and climbed on top of my sister. I held my sister's head and began to kiss her face and her collar, then stuffed my thick and big tongue into her mouth, almost putting the root of my tongue in.

My sister actively responded and put her tongue into my mouth, and I pulled out my tongue and put it back in.

My sister suddenly hugged me tightly with both hands, and then she spread her legs. My cock naturally approached her vagina. The area around the vagina was very wet and smooth, and the cock could be inserted into it no matter what.

My sister held my cock with one hand, aimed it at her hole and said, "Go harder." 』

I pushed my butt down suddenly and with a "pop", I penetrated her in one go.

"Oh, it hurts, it hurts." ． ． "My sister shouted with a comfortable tone.

My cock was inserted into her, and at this moment I instinctively pressed my whole body against her, thrusting my cock back and forth vigorously, going deeper and deeper. As I was doing it, I asked: "Do you feel good? 』

"oh. ． oh. ． ． good. ． good. oh oh. Excellent. "My sister answered shyly and continued, "Oh. ． younger brother. Brother, you play there. The art is really great. ． Thick and...
hard. ． oh. ． oh. It's better to insert it. It's an addiction. ． quick. Put it in quickly. oh. oh. I. ．
I want. oh. oh. oh. ． ． ． ． 』

When I pulled out my cock, the vaginal fluid in my sister's vagina flowed out in streams, and from time to time the vaginal fluid would flow onto my sister's bed; when I inserted my cock into her vagina, because I used too much force, my vagina made a sound of flesh hitting flesh, and her lower body skin was all red from my slapping.

After the two of us hugged each other tightly, kissed, and played from below, we had a lot of fun and soon both reached orgasm. The vagina was contracting and moving. My sister closed her lips as if she was suffocating, while my cock was still moving in her vagina and shooting semen.

Both of them felt very satisfied. They looked at each other and smiled with satisfaction.

Indeed, since that time (which was also the second time my sister and I had sexual intercourse), my sister and I would wait until our parents fell asleep, then secretly be together, hugging, kissing, and caressing each other. Sometimes I would pull my sister's pajamas open, play with her two big breasts, licking, sucking, and biting them with my mouth, while my sister would stroke my head and keep saying "okay".

One night my sister called me to her room and said, "I'm going to take photos tomorrow. I'll make one million yen a day and I'll buy you some nice things when I come back. You have to be patient tonight. I'll play with you tomorrow night. You can play with me as much as you want and as long as you want."

"No, no, sister, I want to play now, take off your clothes quickly." "I said as I pulled my sister's skirt down.

"Don't pull it. The material of the skirt is very thin. Don't tear it!" ! "I grabbed my sister's hands. She couldn't move, so I took the opportunity to hug her and pushed her to the ground. My sister was definitely no match for a man, and she was pinned down by me again.

"It hurts!" No! robber! 』

Without saying a word, I grabbed my sister's hands and pulled her to the table.

"It hurts!" No, don't touch my body. ． ． I'm hurt. 』

At this moment, I remembered that I had used ropes to tie people up during training before, so I decided to use the ropes. I held my sister down with one hand, and used the other hand to take the rope from the table to lift up her hands.

"What are you doing! No! I do, brother. ． You are like this. ． I will be. ． The rope marks were tied. ． ． 'My sister said that the rope marks would not disappear for a day or two, so she couldn't work!

But when the sexual desire came, I didn't care about so much. I finally tied her hands, then started to strip her clothes, unbuttoned her, and then pulled down her bra strap. Her two big breasts were really fun to play with. I slapped them with both hands, and pinched her nipples with my fingertips and rubbed them.

Which man wouldn't want to rape such a beautiful woman? I think it would be strange if it didn't happen.

Then I wrapped my mouth around her nipple, bit it with my teeth and pulled it up.

"ah! Please spare me, I want it. ． I agree! 'My sister cried.

I used my fingers to stroke her erect nipples up and down.

"laugh! oh. pain. ． pain. good. pain. ． ． 'My sister looked very bad and she was still struggling hard.

I suddenly pushed my sister to the ground.

"ah! Oh no! 'My sister's upper body was pressed firmly by me.

"ah! don't want. ． ah! I. already. Agree to do it with you. ． . younger brother. ． Please spare me! 'My sister shouted in a desperate voice.

I suddenly inserted my middle finger into my sister's hole and said to her: "How is it, sister? 』

"Ouch, that hurts!" 'My sister showed a painful expression.

I inserted three fingers into her asshole again. Those three fingers were very thick and my sister was going crazy with the pain.

"ah! My shit. ． Eye. ． ah! That is. ． ． ． ． "My sister said this in pain.

Three fingers were moving up and down in her asshole. It was so tight. Seeing my sister in pain, I felt really comfortable that I could play with a woman so well. After playing for a while, I pulled my hands out of her asshole.

I continued to play with my sister's pussy with one hand, and used the other hand to take off my pants. I held my cock in my hand and instantly inserted it into my sister's pussy and started to fuck her hard. The thick cock moved back and forth. My sister, like before, had sticky pussy juice flowing out of her pussy. The more juice she produced, the more comfortable I felt, and the harder I fucked.

"oh. oh. ． ． oh. oh. ． oh. ． ah. Ahhh. oh. ． ah. ah. ． ． ．
． ．
． want.
． ． . ． ． 'Sister is gone.

While playing, my sister came three times and I ejaculated once. But my sister was so beautiful that my cock couldn't help but get hard again, so I had sex with my sister again. Her moans made me even more excited and I couldn't suppress my inner excitement, and finally I ejaculated again.

Then I pulled out my cock and smiled happily at my sister.

My sister lay weakly on the ground, groaning and mumbling a little angrily, but
