Student's Sister (Family Incest Adult Fiction)

With only two-digit balance in my bank account, I had no choice but to do odd jobs to make a living. The most profitable one is tutoring.
As the trend of tutoring among students in the area is quite prevalent, more than 70% of students have the habit of seeking tutors.
So some people like me who wanted to earn more and spend less joined in.

I found four tutoring jobs, which together provided enough for me to use, and my life began to become stable.
Two of my tutoring students are boys and two are girls. Due to my limited ability, I can only tutor sixth grade students at best.
The two boys are only in the first and second grades and are the only sons, so they are completely useless.
On the contrary, there is a girl who is about to enter Form 4. Her name is Chen Mingxin, and her elder sister who is in Form 5 is called Chen Chengxin.
Both sisters are good-looking. Mingxin already has the potential to be a beauty, and her elder sister is even more delicious, like two flowers in bud waiting to bloom.

However, due to her strict family education, she doesn't even have a boyfriend or a decent friend.

==============================
There is no need to bother with their mothers. I am not interested in old women anyway. But when I tutor them, her mother will definitely be watching from somewhere in the house.
I couldn't even touch their hands secretly, so I had to perform my duties faithfully.
Fortunately, my sister was very talented and understood what I said after just two or three sentences. She also did well in the exams, so I, an amateur teacher, was able to stay on until the summer vacation to help her prepare for Form 5.
My sister Mingxin and I have always had a good relationship. Maybe because we have no friends, she treats me like her own brother and often asks me questions that are not in the textbooks.
I also tried my best to answer her questions, but her mother was present so I never dared to be too presumptuous.
On the contrary, my elder sister Chengxin was much colder to me. She would come home from school every day and would be cold and silent. She would lock herself in her room to study. I had only exchanged ten words with her in the past six months.
It's like he's avoiding me on purpose.
I was once very angry about her coldness towards me, but if I think more deeply, maybe she has noticed the lustful look in my eyes every time I look at her.
I had a good reason to lose my composure. Although Chengxin was only seventeen years old, her body was well-proportioned. Her two small breasts were wrapped in the tight long school uniform, which made people feel breathless. They were at least thirty-three inches long. With her slender waist, long hair, plaintive voice, pure face, captivating eyes, and charming girlish demeanor,
Just imagining having her pressed against my crotch is enough to keep me excited for days.
Mingxin told me that her sister's grades were the best in the class. She had a sweet appearance and was excellent in all aspects, so she was naturally a goddess in everyone's mind.
However, due to my strict parents’ education, I didn’t have a boyfriend until Form 5. The idea of ​​conquering the top students kept growing in my mind.
But as long as her mother is at home, I won't have the chance to do it.
But the opportunity finally came. Chengxin Mingxin's father got a rare long vacation and decided to travel to Taiwan for ten days. However, because his two precious daughters were busy with summer activities, they were unable to take the time.
So they decided to leave them in Hong Kong and the couple went on their own. Mingxin and I continued our tutoring and took care of the two sisters, paying me extra.
Of course I agreed.
Mingxin said that her sister had strongly opposed this decision that day, saying that they knew how to take care of themselves and didn't need me. But fortunately, my sister fought hard for me.
Moreover, after six months of dating, their short-sighted mother felt that I was trustworthy and decided not to look for another candidate. So the fate of the two sisters was decided at that moment.
After seeing their parents off at the airport with the two sisters, I took a car home with them. Cheng Xin's outfit today is eye-catching: her hair is naturally let down, flowing in the wind.
It is much prettier than the ponytail I usually tie at school.
Her face was lightly powdered, and she looked radiant and bright; she was wearing a light blue vest that could barely cover her plump figure. When she inadvertently lifted the collar slightly under the scorching sun, you could see the bra underneath. Her white tennis skirt couldn't hide her bright sunshine at all when she was going up and down the escalator. It was very different from her usual conservative dress. It seemed that she wanted to sneak out to play while her mother was not around.
Sure enough, as soon as we stepped out of the airport, she told us that she was going to play tennis today and would be back very late. Before I could answer, she had already run away.
Forget it, she is like the flesh on the lips that can't be moved away, so I'll just deflower my sister today. In fact, Mingxin’s appearance is definitely not worse than her sister’s, it’s just that she is still in the early stages of development.
Mingxin just turned sixteen, and was entering the mature stage from girlhood. Like her sister, she also grew her hair long, and the two ponytails swayed so adorably.
Her breasts are slightly protruding, yet they look small and cute, and her pretty face shows that she will definitely be a beauty in the future. He was only about five feet tall, probably only reaching my chest.
The fragile body makes people more lovable. She often hugs my arms and asks me questions. Her small breasts rub against my chest and make me feel itchy. Moreover, she trusts me more than her parents and sisters.
I had to rape her to my heart's content and leave her with the most profound memories of her summer vacation that was about to bid farewell to her childhood.
When she got home, she pretended to review biology. I asked her, "Ming-hsin, do you know the difference between men and women?"
Of course, the clever Mingxin immediately answered her question based on her common sense sexual knowledge.
"Okay, now that you know women have periods, have you had your period?"
"It started about two years ago, but my periods aren't always that regular."
Mingxin, who didn't know the truth, answered me without thinking. She couldn't sense the invisible excitement in my heart.
Menstruation means that women are ready for sexual intercourse.
"Then do you know what menstruation means?"
"You can have children now." How smart.
"Okay, then have you seen male and female genitals? I mean real people!"
After saying that, I showed her my already hard penis and forced her to take off her clothes.
"Mom taught me to let others see my breasts and the area below...Mom said these are the most precious things..." Mingxin said, crossing her arms to protect herself.
I don’t care whether it is precious or not, I pounced on Mingxin with my wolf-like appearance. This action scared Mingxin so much that he screamed. But I'm not afraid of disturbing the neighbors.
Because when decorating the house, their mother took the children's study environment into consideration and installed first-class sound insulation equipment on the walls of the whole house. In this way, no matter what they do in the air-conditioned house, the neighbors will not hear it.
Let me give Mingxin a moment to let her moan as much as she wants without any harm.
Seeing my abnormal behavior, Mingxin began to realize that the big brother whom he had always loved was actually a bad person who was worse than an animal.
She was shocked and tried her best to escape from my clutches, but it was too late. I held her in my arms and she couldn't move. Mingxin never imagined that less than two hours after leaving her parents, she would be violated by the person she had always trusted.
After catching Mingxin, I slowly walked into the girl's boudoir, held her hands, and then hugged her to take a closer look at her little world.
The decoration is simple and comfortable without losing the innocence of the little girl. Mingxin felt extremely uncomfortable at the thought that her virginity might be taken away in her own boudoir.
There was a diary on the table, and of course I took it and read it. It's full of the little girl's thoughts.
Among them, I found many words expressing love for me.
"You like me?"
"I used to be, but not now. I didn't expect you to be such a pervert, brother. I...I misjudged you...Let me go or I'll call the police...Ah!"
Reach out and caress her gently. After taking off her white vest, she was revealed to be wearing nothing underneath, revealing a pair of petite, delicate breasts. I couldn't help but suck it.
“No… please, brother…”
I took off her skirt and she was left with only her pink panties. I put my cock to her lips and forced her to suck it for me.
Mingxin tried hard to close her mouth to prevent my penis from entering.
I reached out to her virgin land, which was already a little wet, and I slowly began to massage her.
At the same time, he attacked the girl's sensitive parts.
Mingxin couldn't stand the stimulation, and as soon as his teeth loosened, the penis went straight in. Grab her head and shake it violently, letting the penis vent in her tiny mouth.
Shoot deep into the throat.
Mingxin immediately choked and her face was covered with semen. She was raped unscrupulously by the man she loved. The little girl's heart suffered irreparable trauma.
Just then, I heard the sound of the door opening. For some reason, Chengxin returned home early. Seeing his sister being tortured by the beast until she was no longer human, he was overwhelmed for a moment.
But this one stay was enough to make her regret for the rest of her life.
Without thinking, I rushed over and dragged Chengxin into the house.
I said early on that no one would know what happened in the house after the door was closed, and I have these two sisters in my sight. Because I used too much force, Chengxin fell to the ground on the carpet not far from the door.
The incriminating tennis skirt was lifted up, revealing the panties underneath.
He immediately took off Chengxin's panties and used them as a rope to tie herself up.
By the time Chengxin was a little more sober, I had tied their hands and let them do whatever they wanted. I didn't expect to kill two birds with one stone. If I had known, I should have held back.
Ignoring their shouting and wailing, I carried them into the master bedroom. There was a seven-foot-wide bed in the room, so there was plenty of space to teach them a lesson.
The two sisters each have their own beauty. Mingxin's face was covered with semen so that she couldn't open her eyes. She just shouted, "Sister, come and save me." I said your sister couldn't protect herself either, and then I threw myself on Chengxin.
The body of a 17-year-old virgin is indeed very different. Chengxin's still developing breasts trembled in my palms through her clothes, and her vagina swelled up enough to accommodate my penis.
The desire that had been buried in my heart for nearly half a year was finally released, and I couldn't help but kiss Chengxin.
The seventeen-year-old girl holds beautiful fantasies about future happiness.
But all this disappeared with my kiss. My precious first kiss had been monopolized by the hideous face in front of me. I didn’t know what kind of humiliation I would suffer in a moment.
"Which one should I rape first? I'm not in a good mood today. It seems I can only choose one of the two. Which one of you is willing to go first?"
Facing two silent bodies, I slowly approached my sister.
"No! You beast, if you want to vent your anger, just rape me. You've always wanted my body anyway, so come on if you want." As he said this, he puffed out his chest, closed his eyes, and looked indifferent.
I saw early on that Chengxin really loved her sister, and this try was indeed effective.
"Bah! Who said I would come if you were willing to let me rape you? I'm going to fuck your sister half to death in front of you!"
"You bastard...what do you want me to do to make you let my sister go?"
"It's very simple. Just do as I say."
He took out a camera from his waist and ordered Chengxin to make lewd poses, such as spreading her legs and holding her breasts with both hands, kneeling on the ground, lifting up her skirt and taking off her underwear, and raising her buttocks.
The arch bridge allowed me to take close-ups of her vagina and other actions that would have been extremely embarrassing for a young girl. Taking pictures is secondary. What I want to see most is this ice beauty with a red face and hurt self-esteem.
Chengxin was a well-educated and well-mannered girl, and had never suffered such an insult in her life. But I could only endure it for a moment, and could only reluctantly fulfill my excessive demands in humiliation.
I hope someone comes to rescue them.
After being played with by me for nearly half an hour, Cheng Xin was already exhausted physically and mentally. She watched me take obscene photos of her frame by frame.
Her usually arrogant and cold look had been replaced by helplessness. She could only lower her head and tidy up her messy clothes.
Now it was time for the second part of the humiliation. I asked her to kneel on the ground and pretend to be a big cow for me to ride, and walk around the house. How could poor Chengxin's body bear my huge weight?
He fell to the ground after crawling a few steps.
I wouldn't let her go so easily, so I found a whip and whipped her elastic buttocks when she stopped. The sound of the whip was so pleasant.
I walked and squeezed her breasts, saying that I wanted to milk the big cow. As a result, Chengxin, who had suffered so much humiliation, finally led me into her room and raped her with great difficulty.
Entering Chengxin's boudoir, I lay on her soft bed and asked her to crawl over and give me a blowjob.
I didn't expect Chengxin to firmly reject my request and ignore my threats.
He also shouted that he would bring me to justice.
Forget it. Seeing her half-exposed body, I had played with her enough for today anyway, so I didn't care about oral sex or not. I forcibly carried her to the bed and started raping her.
I had taken off Chengxin's bra early in the morning, and after pulling off her vest, her mouth-watering breasts were exposed.
After my repeated abuse, her breasts have become red and swollen. He rolled up the tennis skirt, exposing the girl's vagina, and caressed and teased it slowly.
Chengxin had already been tortured by me beyond her limits and wanted to leave this place at all costs. Unfortunately, his body and mind had already been completely destroyed, and he was no longer able to mount a final resistance.
I spread Chengxin's legs, took out my penis and was about to break her virginity.
The penis slowly squeezes into the girl's vagina, enjoying the pleasure of the tight vaginal wall. I was not in a hurry to break her virginity immediately, but just delayed the time to let Chengxin further feel the fear of losing her virginity. "Please... don't..." Seeing the penis reaching the hymen, Chengxin made a final plea.
"Three, two, one, here I come!"
With a thrust of his lower body, the penis penetrated Chengxin's hymen in one breath.
No, I have nothing! "
Chengxin screamed in sadness. She has always been a girl who values ​​chastity and has always wanted to give her virginity to her husband. Unfortunately, it's too late now. I have become a withered flower.
This kind of thinking has a deeper impact on a proud girl like Chengxin.
"Face the reality! You're a beautiful girl who is only worthy of being raped by me!" While raping me, I continued to attack her self-esteem with words, doing everything I could to increase her pain of losing her virginity.
After more than a hundred thrusts, I finally couldn't hold it anymore and whispered to her, "Cum inside me, Mom?"
Chengxin immediately started to tremble. She knew there were ways to prevent pregnancy after being raped, but she absolutely did not want her young uterus to become a flesh pot for someone else to irrigate with semen.
But it was too late, I had already poured all my semen into her body.
"Well done, you have saved your sister's virginity today. But look at the clock..."
It turned out that I had been playing with them for 6 hours since 6 pm, and it was exactly 12 o'clock now. I walked over to Xiang Mingxin and thrust into her while she was tired and sleeping.
The pain of losing her virginity woke her up and she continued to accept endless rape...
