My sister and her good classmate (sexual knowledge adult novel)

My sister and her good classmates

On Friday night, I couldn't help it again, so I sneaked into my sister's room again while she was still studying.

I masturbated and took out her hello kitty panties from the closet. I didn't expect that when I was about to cum, I heard my sister

I heard footsteps upstairs. Although I put my underwear back, I didn't have time to leave my sister's room, so I hurriedly hid in the

I was under my sister's bed, waiting for the right moment to leave. My sister came in humming and locked the door.

The sheets at the edge of the bed covered me, so my sister didn't notice me.

"Boo!" The school skirt that my sister took off fell to the ground. She picked up the school skirt and threw it on the bed. Then the bed also "

Bubble! "I thought it was my sister who took off her top, but her bra slipped off the bed.

She walked to the bed, picked up the bra and put it back on the bed. "Swoosh!" The girl raised one foot and then the other.

She even took off her underwear. Although she wanted to peek, she was afraid of being discovered by her sister. She walked into the bathroom naked.

I thought I could leave the room, but my sister didn't close the bathroom door. I don't know how long I have to wait before I can leave.

I heard a strong sound of water splashing in the bathroom. I thought my sister was probably peeing. What a pity.

Can't see it anymore.

After the rustling sound of water came the sound of the shower head. My sister started to take a shower. I didn't expect that she only closed the door but not the

The bathroom door... now she can’t get out. After taking a shower, my sister sat on a chair and started doing her homework. Oh my God! Look at the sample

My son can't go out today because my sister usually doesn't go to bed until one or two in the middle of the night when she starts studying.

I fell asleep unknowingly during the waiting time, and only woke up slowly when I heard a strange sound.

I checked the time. Wow, it’s already half past one. Is my sister still not asleep? I lifted the sheet again a little bit,

There was a piece of cloth on the ground in front of me. Upon closer inspection, it was the Kitty underwear I used to masturbate in the afternoon, but it looked wrinkled.

There was some bright reflection in the crotch, and then I heard a strange sound, which should be coming from the chair.

I glanced up and saw my sister leaning on a chair, her right foot on the bed, her right white buttocks

The entire red vagina was exposed in front of me.

My sister's vagina is really beautiful, with sparse pubic hair, red and tender labia, protruding clitoris, red anus,

There is also a faint little hole, which reminds me of the A pictures I have seen before. There is nothing comparable to it. The girl's fingers are constantly in her vagina.

The other hand was on the small breasts, rubbing the little grapes that stood up, and the fingers were on the small hole.

The vaginal fluid that came out was directed to the clitoris and gently rubbed. The right hand reached in from behind the buttocks and gently rubbed it with the fingers.

I pushed it outside the vagina, watching the vagina and the small anus expand and contract, and gradually speed up. Not long after, my sister moaned.

The body twitched for about half a minute, and then gradually stopped twitching as the sound became smaller.

My sister became limp and lay on her back on the chair. It took her a long time to recover, but she fell back on the bed.

I didn't expect that today I would see my sister masturbating at a close distance.

After more than ten minutes of silence, I thought my sister had fallen asleep. But when I was about to crawl out of bed, she

The sound was developed, but this time the moaning sounded a little different, as if something was making a sound.

The body kept rolling on the bed.

With a "pop", a booklet was pushed off the bed by my sister. She didn't seem to react.

Looking at the fallen book, the cover reads "... Sex..."

Wow! Could it be that my sister learned to masturbate after reading this book? I carefully pulled the book in.

The first few pages are all illustrations of the sexual structure of men and women, and there are also highlighter marks on the "proper nouns".

The next few pages were about masturbation methods and props. As I was flipping through the pages, I didn't expect that my sister had read at least half of the book when she suddenly found

I found a bookmark in the middle, opened that page, wow! It is SM, and there are several pictures teaching the way of binding.

The note reads:

"... tying oneself up with ropes and imagining oneself being raped by bad guys is usually due to the entanglement of moral values.

You may reach another climax, especially when you imagine being fucked by your male relatives (father, elder brother, younger brother, male classmate)

……)……」

Listening to my sister's humming voice mixed with "Mmm...Mmm...Mmm", is she fantasizing about being fucked by me, her brother?

I was raped by my brother and I was shouting “Brother…no…”

I continued to flip through the booklet, and the next few pages contained exciting information about SM, STD prevention, pregnancy...

Maybe my sister hasn't read it yet, so she didn't highlight the key points with a highlighter. When I turned to the last page, I found a few photos sandwiched between them.

In the photo, there is a plastic ruler and next to it is a bright red straw mushroom about 16 or 17 centimeters long and 4 or 5 centimeters thick.

Growing in a pile of black grass

Huh? That's weird, that's not a mushroom, that's a penis, that penis is probably the same as mine

Big, huh? The more I looked at it, the more they looked alike. When I saw the birthmark on the inside of my thigh, oh my god! That cock is mine.

I have no idea when the photo was taken. Look at the date: 2000.6.12-11:4

7. It was the Monday before last. That day… that day my friends came to my house to celebrate my birthday. They forced me to drink a lot. It was strange.

I was only drinking until about nine o'clock, and then I passed out. When I woke up the next day, my head still hurt. Could it be that

My sister must have taken this photo when I was unconscious.

The next few pictures are even more incredible. One is a picture of the sister holding the penis with both hands and sucking it in her mouth.

The last photo is of my sister's surprise and her face full of semen. My sister actually took advantage of me when I was unconscious.

I wish I was still awake at that time, but as I looked at the photo, I felt something was illogical.

When I heard my sister's rapid moan, it became quiet again after a while. I guess my sister had an orgasm again.

Thinking about how my sister, who is usually well-behaved, could be so slutty in private.

I waited quietly for almost half an hour. My sister masturbated twice. This time she must have been too tired to fall asleep. I was careful.

I crawled out from under the bed, slowly stood up and looked back, only to find that my sister had tied her eyes with a white cloth again.

She put a piece of transparent tape on her mouth and tied her wrists with a scout rope. What's more exaggerated is that she tied her legs together.

Spread them apart and tie them up with scout ropes and scout sticks to form an M shape, just like the picture of the bondage.

He fell asleep without even untying his bonds.

Looking at my sister's naked body tied up by herself and her pussy full of cum, I couldn't help myself and said, "I want to fuck her!"

...I want to fuck her." After tying the ropes around my sister's hands and feet tighter, I bent down to lick her small and cute breasts.

The bright red nipples also slowly hardened, and my sister seemed to feel it again. Maybe I forgot to shave and pricked my penis.

My sister unconsciously tried to push my head away with her hands

As she was taking off her clothes, her sister seemed to wake up from the harassment and wanted to untie herself.

I was afraid she would untie the rope, so I immediately held her down. Then she realized that someone was on the bed, and now she was

Her hands and feet were tied with ropes and sticks, and she was completely at the mercy of others. Although she struggled hard, I held her down.

The white cloth on my sister's eyes seemed to be oozing with tears. I easily pushed the scout stick forward, and my hands were also wet with tears.

The military stick was pressed down, and the whole vagina was completely exposed in front of me. I buried my head between my sister's legs and kept tongue

He licked the overflowing vaginal fluid wildly on the clitoris.

Seeing that my sister had stopped resisting, I stopped my action and then used my other hand to lift the erect old

The second one pressed down against the small hole, and the sister seemed to feel what was going to happen next, and her body kept moving

I was shaking, but I couldn't stop the burning desire. I pushed it in slowly, and the glans broke the hymen.

At that moment, my sister arched her waist in pain. I continued to push forward, and the glans was like a sharp blade.

I opened my sister's tight vagina and finally reached the entrance of her uterus before I stopped. My sister seemed to faint from the pain.

I slowly began to pull out, the crown of my glans penis was rubbed tightly by the layers of tender flesh in the vagina, and every time I pulled out a little

Click it, and you will feel as good as an electric shock.

I pushed my penis into the small hole again, and my sister twisted in pain again.

After a while, the sister may be numb and motionless, so I held her ass with both hands and started to fuck her hard.

My sister's pussy was so tight that I couldn't stand it after less than five minutes. I pushed deep and hard and ejaculated.

The semen was ejected into the sister's body, and the gradually softening penis was pulled out, and the semen immediately overflowed, along with the red and

The vagina was covered with vaginal fluid, making it a mess.

At some point, the white cloth covering my sister's eyes slipped off, and she stared at me for a while with tearful eyes.

Son.

"Sister, I'm sorry! You're so beautiful, I can't help it... Please forgive me..."

"Wuuuu! Wuuuu!" My sister kept sobbing...

After a long while, his eyes finally changed from being the same as before and became softer.

"Sister...please forgive your brother...okay..."

The girl finally nodded, I tried to let go of her hand, she didn't attack me, and then gently put her mouth

I was about to tear off the tape, and then my sister suddenly spoke.

“It hurts! It hurts!”

"sorry!"

"I...I...it's my first time~brother...you just...oooh~it hurts!" My sister pinched me hard.

A few times, almost black and blue

"I'm sorry! But seeing you studying so hard on this book, I couldn't help but want to do an internship..."

"Book……?"

"Here, this is the book called "...Sex..." You not only highlighted the key points, but also included my photo."

I saw my sister's face turned red with shyness, and I helped her untie the ropes on her body.

"Sister, I'm sorry. I came inside you just now. Is it okay today?"

"Yeah! It's okay today!"

"Did you just ejaculate?"

"Brother is so rough, it hurts so much, how can I possibly cum?"

"Sister...I want more..."

"No... it's... numb and painful there."

I didn't force my sister. Looking at my sister who was sweating all over, I lay on her and helped her deal with her private parts.

The girl's vagina was red and swollen, and a mixture of vaginal fluid, semen, and blood was flowing all over her private parts and the bed sheets.

I was too hard, and I opened the girl's swollen labia majora, and inside was even more terrible. In addition to the mixed liquid overflowing, the vaginal opening was

The hymen was torn into five pieces, but some of the blood on the wound had slowly solidified. It was really heartbreaking to see

pain.

"I'm sorry! I hurt you just now, does it still hurt?"

"Of course it hurts!"

"I'm sorry! Don't be angry."

"Okay! I forgive you! Bro, I need to go to the bathroom."

I moved away, and my sister slowly sat up with her hands. She wanted to move her legs, but the pain in her private parts made her

And can't move.

"Let me help you."

I picked up my sister's weak body and went into the bathroom. I gently put her on the toilet and sat her down. However, I didn't hear the water running.

Voice.

"Brother, please go out for a while."

"What?"

"Please stop looking, I can't pee anymore!"

"How can this be possible? Even if you don't allow me to watch it, I still want to watch it."

I opened my sister's thighs, and my fingers kept wandering around her urethra, while I whistled softly.

Finally it worked, a strong stream of water spurted out from the urethra, and my sister shyly covered her face with her hands, and then she smelled a

It smells bad, it turns out that even feces have come out.

"Oh~ so thick and big~"

"Don't look! I just told you to get out!"

After a while, my sister finished her poop, slowly stood up and leaned against me, gently moving her private parts and anus.

I wiped it clean, but her expression told me that she was still in pain. I then helped her clean her sweaty body and watched her

After cleaning her asshole, my lust rose again. I suddenly grabbed her ass with both hands and pushed my cock against her from behind.

Sister's asshole.

“Ah! No! Not there!”

"Why not?"

"Yours is so big, and that one is so small."

"Your poop just now is almost as thick as my dick, so it can go in."

"No, I will be in so much pain tomorrow that I won't be able to walk."

After struggling with my sister for a long time, my sister begged me to avoid having her asshole bloomed, but the virginity that had just been opened

The female hole is not immune, so the penis is moved forward to press against the labia, and then pushed into the vagina again.

Push it in halfway.

"Oh, it hurts! Be gentler!" My sister screamed in pain and her whole body went limp.

I gently held my sister in my arms and asked her to kneel on the floor, holding onto the bathtub with both hands, using the lubrication of her vaginal fluid to make it go smoothly.

I pushed it all the way in. Although I had just ejaculated, I was less sensitive this time, but I was still entangled by the little hole that had just been opened.

It was really hard to resist, as if to lock the second one, and gently rubbed the sister's breasts with both hands.

The two nipples on my sister became hard again. As I slowly thrust in and out, my sister began to moan. I think my sister must be

I thought I could get used to it, so I increased the speed, and all kinds of strange moans came out of my sister's mouth and nose.

In the end, his upper body was limp and he was lying on the ground, his buttocks twisting wildly.

"Ah~~Ah~~I'm leaking~~I'm leaking~~"

The vagina continued to contract strongly, finally allowing the girl to reach her first orgasm after losing her virginity, and her whole body kept pumping

While twitching, I took the opportunity to shoot my second shot into the sister's vagina. This time, it took her a long time to calm down.

Finally, after I cleaned her up again, I helped her back to bed. My sister asked me to sleep with her, but

She fell asleep. Looking at her innocent face while she was sleeping, I couldn't associate it with how she looked just now. I kissed her softly.

I also fell asleep with her forehead.

The next day, when I woke up, my sister was already up. She was coming out of the bathroom, but I saw her legs opening slowly.

As I walked over slowly, I couldn't help but laugh.

"What are you laughing at! It's all your fault! It stinks!"

"I'm sorry. Seeing you like this makes me feel so sad. Does it still hurt?"

"It's a little better now! If your parents find out, you'll be dead!"

"No! They won't get up until 8 or 9 o'clock, but you probably can't ride on your feet.

It’s time to ride a bike. I’ll take you to school. "

"Hmm~Okay..."

After driving her to school, I went back home to prepare for class and happened to meet my father in the kitchen.

"Next time, keep your voice down when watching porn. If I hadn't stopped your mom last night, she would have rushed upstairs and beaten you up."

Dad whispered...

"Thank you, Dad!" (Wow! Fortunately, Mom didn't rush over, otherwise my sister and I would be finished)

"Besides, it's not good to disturb your sister's sleep! She still has classes and exams! Remember! There won't be a next time!"

I went to class, but I couldn't concentrate at all. My mind was full of thoughts about what happened last night.

I always feel that it's a bit weird, but I don't know what's wrong.

After lunch, I went to walk around with my classmates. There is nothing in this place except for many historical sites.

There are always tourists. As usual, there is another couple who wants us to take pictures of them.

Then I suddenly remembered and figured out the problem that had been puzzling me.

After school, I came home. My parents were out setting up a stall. The whole house was empty. When I went upstairs to my room, I passed by my sister.

The girl came back to the room and had a sex interrogation with her. She finally confessed her accomplice. - Liu Shi

should.

I remember that she lived just next door, and was my sister's classmate. She was quite cute. I didn't expect her to be like this.

I was precocious. I used to come to discuss homework with my sister. Many times, I didn’t go home until one or two o’clock, and then I slept with my sister.

The photos that day were taken by Shiyi, and the book was also given to her by her. Even the rope and

She also lent the stick to her sister. I didn't expect that such a pure-looking girl could turn her sister into a little slut.

Baby, if I get the chance someday, I will definitely fuck her.

On Sunday morning, my parents went to set up a stall at the temple entrance and would not be back until the evening. I was originally going to play basketball with my classmates.

I'm a basketball player, but he broke the promise. Now my sister and I are the only ones at home, so I plan to have a family game with my sister.

I walked to my sister's room and heard her moaning from inside. I gently opened the door.

I found my sister lying on the bed with her back to me like a frog, masturbating, and her hands were tied with ropes.

So I decided to give her a surprise and use my superb hidden skills from playing Tianzhu to secretly

I walked behind the girl and quickly pulled out my penis and pressed it against her vaginal opening. I held down her hands with one hand and

I pressed my sister's butt with one hand, and pushed my penis forward, pushing the glans directly into her vagina. Strange...

Why is it so tight...

"Ah! It hurts, it hurts!" The girl's body kept twisting.

"Hurt? How?" I paused.

"What? You are Shiyi!" I looked forward and found that Shiyi was already in tears due to the pain.

"It hurts! Take it out!"

I really came uninvited. I didn't expect that I wanted to fuck her yesterday, but today I really did it. Shiyi still

She was still struggling, but I didn't let go. Instead, I held on tighter and pushed my dick into her vagina.

I didn't expect the pussy to be so tight. Every time I thrust in, Shiyi would struggle because the pussy juice was so tight.

It wasn’t enough, so Shiyi screamed in pain.

“It hurts!”

"Don't you also fantasize about being raped?"

"No more! It hurts! Ouch!" Shiyi began to sob.

"You can't do that! I'm going to punish you!"

I made up my mind and started to pull out. She screamed every time I moved, but there was an empty house next to her.

It was a main street and no one would hear her screams, so he thrust harder, and her voice could only be described as a wail.

The pussy was still tight and it hurt my dick, so I caressed her breasts and pussy more gently.

I pinched her breasts which were one cup size bigger than my sister's. They were probably softer because they had more fat. I pinched them with my fingers and played with them.

The other hand also reached into the vagina and rubbed the clitoris continuously. It took a long time to let the vaginal fluid flow out.

She seemed to have adapted to it and a slight moan replaced it, and I stopped.

"What? Are you feeling pleasure?"

"..." Shiyi remained silent

"Do you want to continue?"

"..." Shiyi remained silent

"I don't want to! Then I'll take it out!"

“No…don’t…”

"Do you want to? ... or don't you want to?..."

"…think…"

"Very good! As long as you don't tell anyone about this! I can treat you gently and make you feel comfortable!"

Shiyi thought for a while before nodding, and I started thrusting again, but this time I slowed down and enjoyed it slowly.

She closed her eyes to feel the wet and tight pussy, but she got into it right away.

It was like a spring that kept flowing out and the moans were getting louder and louder, and I also increased my speed along with the moans.

"Hey, hey! You're just like my sister! Once you start, you don't want to stop."

"......" Shiyi could only close her eyes and accept it, because her body had already given it away...

After inserting for a while, Shiyi's whole body trembled and reached orgasm. The tender flesh in her vagina kept contracting, and I couldn't bear it.

So I thrust it in deep and started filling it. I waited until the vagina was relieved before pulling out the soft penis.

The white liquid mixed with the red liquid flowed out from the broken hole. It turned out that Shiyi was also a virgin. However, at this time,

Suddenly a voice came...

"Brother! Do you like it?"

I didn't realize that my sister was standing behind me. It turned out that Liu Shiyi was so easy for me to fuck her.

I had a threesome with my sister and Liu Shiyi the whole afternoon, but this time it was my turn to be sore.
