Chapter 4: After my sister was fucked by me at school, she learned to attack her at night (brother and sister, sex education, teacher and student, night attack)

Is it Xiaotian?

It's me, who are you?

Haha, it turns out that he is not here to attend the class. You may have never seen Teacher Chen in your physiological health care class, right?

A disdainful voice came from the other side of the phone.I...had never seen it before.

I am Teacher Chen, a physiological and health care class in the university. Sister Chen asks me to help you.You want to get close to the principal, right?I can at least help you cover up the last time you were naked.

Um?I was so excited when I heard this.

You said, I'm listening.

Forget it, let’s talk about it when we meet.

She made an appointment with me and we met in the park corridor.

Are you the perverted and stinky man who took off all his clothes and walked into the principal's office?

As soon as she met, she gave me a polite comment.

Well...yes...

What else can I say? Whatever she says is the quilt, and I have to ask for help.

Puff...hahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahaSorry, I couldn't help it...

I looked at this woman who smiled extremely arrogantly with a dark face.

Cough, well, just get to the point. I told the principal that you are a new teacher assistant and forgot the joke after class.The principal believed it.But you also know that the principal attaches great importance to school education, especially physiological and health care classes, which is the top priority.Because many students do not study hard in class, they still have to participate in training classes after graduation, and crackdown on training classes must start from the root.So... you will start to come to the school tomorrow to be my teaching assistant.

What does it mean is that I can not only return to school, but also become a faculty member?

That's right, that's it.Otherwise, this excuse would not be easy to hold.If it doesn't work, I'll find a reason to open it for you later.

No, no, I love teaching too much!

I quickly interrupted her. After all, the probability of becoming a faculty and staff contacting the principal soared, and the fool gave up.

Well... Although I don’t know why you are so energetic, it’s just a good phenomenon!Since you plan to have a good class, then when you go home today, including tomorrow, eat more aphrodisiacs.When we come to school the day after tomorrow, we will start classes in the afternoon!

Um?Why do you need to strengthen your aphrodisiac Ah later?

Nonsense, you need to be a teaching aid to teach students to have sex. If you don’t strengthen your aphrodisiac, do you want me to strengthen your aphrodisiac?

...I knew that the jobs that men do are always betrayal.

I was honest and obedient, and I showed off no less than thirty oysters in the past two days.

After all, after listening to her description, I am alone in charge of the students in a class...

Time soon arrived as scheduled. I arrived at the university and went to the office to prepare for the afternoon class.

(There is no so-called high school in this world. Primary and junior high school education is directly college education. Because women can get pregnant very early, in order to help them learn relevant knowledge as soon as possible, freshmen are actually only 15 or 6 years old, and even 13 years old.)

When I followed her into the class, I was stunned.

Is it really such a coincidence?

My sister is in this class!

Oh my God, I pretended to be calm and pretended not to know my sister.

My sister didn't seem to have expected that her teaching assistant would be me.

I quickly calmed down and looked around the class, and found that there were about 40 people sitting neatly in the class. Although it was different from the university class with more than 100 people in my impression, there were also quite a lot of people.

The students are quiet. Starting today, this teacher will serve as the teacher Xiaotian in our class’s physiological health care class.There is not much age difference between you, so you can call him Brother Xiaotian.We have invited Brother Xiaotian to be a nude model for everyone. Later, you can understand the difference between men and women through observation of male entities.This is much more educational than the dry pictures in your junior high school books!

At this time, I wasn't listening to her at all. My mind was full of my sister here... but it seemed that my sister was much more calm than me?

After Teacher Chen finished introducing it, the audience, Loli?

Or the young girls applauded with face.

But his eyes were always staring at me.

I was a little overwhelmed.

Xiaotian, why are you standing there?It's time for you to take off your clothes!What do you think of me wearing so much?

I bit my teeth and took off the only sweatshirt I had on my body, revealing my pretty muscular breasts.

Please take off your pants, too.

I glanced at Teacher Chen, and she looked at me firmly, so I had to take off the sports shorts again.

And you also need to take off these briefs.

Teacher Chen continued.

Will you be naked if you take off again?

Standing naked on the podium in front of so many female classmates in the class, it was actually fine. I was used to working with my body, but this time it was different!

My sister is still down there!

I took off my only underwear again, and my hands blocked the hidden part of my lower body.

More than thirty pairs of eyes in the class looked at me in unison. Although I often took off naked in front of women, I still felt a little perverted when facing more than thirty women who were considered high school students in my world at most.

Take your hand away, what do you think of the classmates?

Teacher Chen reminded me.But, I was still a little shy, after all... my sister is...

I still took my hand away.

Just...how to say it?

In the past world, I was a pervert and watched the pictures of beautiful women, but the first time I was a girl, I still saw so many rapes.

Although I was reluctant to admit it, I was hard... because when I thought about the possibility of having sex with so many girls in my mind, my male genes were very excited and became hardened in shame.

Wow, it's so big. The picture says it's generally about ten centimeters?Why is this teacher so old?

The main reason is that Teacher Xiaotian is a high-quality man, and he is very high-quality in any aspect.

Teacher, so big means high quality, right?

Of course not. The standards for excellence are widespread, and length is just one of them.It also includes the perimeter, that is, the thickness.Hardness, shape, and even invisible things such as sperm motility, sperm mass, sperm aberration, etc.Of course, the higher the value, the better.Teacher Xiaotian is far superior to ordinary people in any indicator, so it can be said that he is of high quality.Teacher Chen explained that the students listened with relish.

Okay, in order to compare teaching with male body, I would like to invite another female classmate to show off the female body.Which student is willing to come up?

Teacher Chen looked around, but no girl responded.

Since no classmate is willing to come up, then I will name it?Xiao Ai, is that OK?

I was looking at Teacher Chen in surprise.Because she accurately pointed out my sister!My sister had already stood up from her seat, and she walked to the front of the podium a little shyly and asked.

Teacher Chen, do I also want to take off my naked body?

Teacher Chen nodded and said

It's Ah, is that OK?Little love?Will you be shy?

My sister hesitated for a moment, and I thought she would not agree, but my sister looked at Teacher Chen and said

OK.

After saying that, the sister took off her skirt. She was wearing a set of blue floral lace underwear. The underwear was designed very sexy. Except for a piece of paper-sized cloth in front that was embroidered with a few flowers, the rest were almost all transparent.

My sister seemed to have made up her mind. She took off her underwear without any hesitation and stood beside me openly.

This is the first time I saw my sister naked, but I didn’t expect her figure to be so good!

She usually wore loose pajamas to cover up her bust. Only then did she find that her breasts were big and firm, her abdomen was smooth and tight, her legs were long, and her buttocks were slightly upturned, making her look very tall and beautiful.

At this time, the chattering sounds could not be hidden in the classroom.

But at this time my brain was in a state of downtime and I had no idea what they were doing.

I tried my best to endure it, but the light from the corner of my eyes was very honest and stayed on my sister's naked body.

At this time, Teacher Chen was teaching them the difference between men and women's bodies.The students were also chattering about something, but I couldn't listen at all.

Suddenly, I noticed that my sister was sitting on a chair, exposing her vagina to the students!

What is she doing?!

I looked shocked, but I only heard Teacher Chen explaining the physical structure, precautions and maintenance methods of women.

I breathed a sigh of relief.

At this moment, I could no longer help and turned my head directly to my sister's naked body.

Although I was behind her, her little tender pussy looked like, her breasts kept hooking my eyes.

Before I knew it, my cock was already high and even began to drip down.

Sin, this is my sister Ah!

Although there is no ethics in this world!

But she is still young!

I can't do this.

I can't do this.

I kept telling myself in my heart.

Okay, the next thing is today’s focus, that is, how to have sex, or sex.So, please ask Xiao Ai to demonstrate sex for the students?

My sister shook her head and said

How do I demonstrate Ah?I myself...

My sister means that she lacks an opponent.

I looked at my sister in shock, but my cock under my crotch was so swollen that it seemed to be about to explode.

After all, I'm the only one here.

Speaking of opponents, wouldn't that be...

Teacher Chen walked to his sister and said

This is actually very simple. For example, the tip in my hand is the male penis. Look, inserting the penis into the vagina like this is sexual intercourse.

While explaining, Teacher Chen carefully inserted the instruction stick in his hand into his sister's vagina.

Teacher Chen thought his sister had never done it.

But I think so, most families cannot give birth to boys themselves, and even if they give birth to them, it is likely to be useless, so many people do not have men in their families.

As for pregnancy, it is artificial insemination based on government-distributed semen.

It is said to be a distribution, but in fact, you still have to apply and queue up.

Sometimes it may take one or two years.

Teacher Chen, the instruction stick in your hand is so thin that you can certainly insert it, but Teacher Xiaotian’s penis is so thick, how can it be inserted?

Yes, classmate, your observation can be said to be very careful.In fact, before sex, men and women need foreplay, in order to make the male penis fully erect, they need foreplay, such as kissing, stroking and oral sex.

Teacher Chen walked to me, she reached out and held my cock, gently stroked it a few times, and then said

But you also saw that Teacher Xiaotian’s penis is already very thick, right?

This is actually because our teacher Xiaotian is a very scarce high-quality man.But most of the men you meet in society cannot achieve such an effect.So now, please come up and touch Teacher Xiaotian’s penis to actually experience how to help a man’s penis fully erect.Of course it's fine to pretend it's still small.

I could hardly believe that Teacher Chen actually wanted all the girls to come up and touch my cock. I was a little at a loss. On the other hand, my sister was still sitting naked on the podium and smiling at me without saying anything.

Please line up and touch them one by one in sequence. Please don’t use too much force when touching. The male penis is sometimes very fragile.

So more than 40 female classmates lined up in front of me. The first girl who came up touched my cock a little shyly and quickly retracted her hand, which made the girls behind laugh.

Then the girls who came up became much more courageous. They gently stroked my cock like Teacher Chen, and one of them touched my scrotum with his hands.

Then a brave girl came.

She first used gloves to get my cock a few times, then touched my scrotum. When I thought it was about to end, she squatted down and opened her mouth to hold my cock and sucked it a few times.

I looked at her in surprise and looked at Teacher Chen again. Teacher Chen didn't even say accusation, as if she still praised this bold move.

The girls next followed, some timid people turned around after touching them, and some brave people also imitated their classmates to open their mouths and hold their cocks and suck them. Under the constant stimulation of so many female classmates, my cock quickly became stronger, and my glans was raised high, and from time to time, there were a few drops of them dripping from time to time. I don’t know if it was prostate fluid or the saliva of students.

Okay, students, please see, Teacher Xiaotian’s penis has been fully erected in the foreplay just now, and this is the function of the foreplay.In fact, in addition to touching and oral sex, there are also sensitive ties, applications of toys, etc., and there are various methods.If you meet a man who has no reaction, students should not give up easily. It may be just that the foreplay is wrong. After all, we cannot ask everyone to be as good as a teaching assistant, so we should be more tolerant to them.

Teacher Chen!Is it time to get to the point?

This kind of thing actually depends on whether both parties are willing, especially all classmates. Never be tempted by a man. If you want to have sex, you must say it bravely!By the way, back to this class, Xiao Ai, do you agree to have a one-time sex demonstration with Teacher Xiaotian so that the students can get a chance to witness it and learn how to have sex with the opposite sex?

Does Teacher Chen really want her sister and I to have sex demonstrations in front of more than 30 female classmates?

I couldn't help but be surprised and opened my mouth wide and couldn't close it for a while.

But then I thought about it, Teacher Chen didn’t know the relationship between me and my sister.

However, just as I was thinking about it, my sister nodded without hesitation.

Since Xiao Ai agreed to have a sexual intercourse demonstration, Xiaotian Assistant Teacher, please come here.

Teacher Chen signaled me to walk to the front of the podium

Students, in order to observe more clearly, you can come to the podium, but please do not interfere with the teacher’s sexual intercourse with Xiao Ai.

So more than 30 female students in the class gathered together.

I was both excited and nervous. Do I really want to have sex with my sister in front of so many girls?

I held the base of my cock with my right hand, but I didn't dare to insert my glans into my sister's vagina.

Teacher Chen gently pushed me behind me, so I pushed forward and pressed my glans against my sister's clitoris.

My sister said oh gently, adjusted the angle slightly, and my cock was inserted into my sister's vagina.

Wow!Go in!

Several female classmates started shouting.

That's so big!I can actually go in!

Teacher Chen explained

This is sex.Xiaotian's assistant teacher's penis has been successfully inserted into Xiao Ai's vagina.Of course, this kind of insertion must be fully wet for the woman's vagina, otherwise the woman's vagina may be damaged due to dryness and then feel uncomfortable.

So how can it be fully moist?

Men can caress women and help women with oral sex to make their vagina fully moisturize.Teacher Xiaotian, you can try it out for Xiao Ai to have a blowjob first!

Teacher Chen answered the question without looking back.

I looked at my sister, and she nodded at me with a rosy face.So I pulled out my cock, squatted down slightly, stuck out my tongue and licked my sister's vagina a few times.

Teacher Chen said with a smile

It seems that our teacher Xiaotian is not proficient in oral sex.You can lick Xiao Ai's labia and larvae back and forth first, and then tease her clitoris with the tip of her tongue, which is the most sensitive sexual organ for women.

I am not skilled, but this person is my sister, I am a little... Oh, forget it, now that I have started to do it according to the method taught by Teacher Chen, and I just treat it as teaching.

After a while, my sister began to scream excitedly.

When a woman makes this heartfelt voice, she means she already feels sexually excited, which is usually a moan.Look, there is already vaginal fluid flowing out from her vagina.

Really!A lot of vaginal fluid flowed out of Xiao Ai!

Teacher Chen, Xiao Ai's vaginal opening seems to be still squirming!

The students observed it very carefully!This kind of squirming means that Xiao Ai already wants her penis to be inserted.Teacher Xiaotian, try inserting your tongue with your try.

I obediently stuck my tongue into my sister's vagina and thrust in and out.My sister soon let out another louder moan.

Xiao Ai seems to be a bit difficult to answer questions, so Teacher Xiaotian, what do you feel?

I feel that the inside of my vagina is wet and slippery, and water seems to seep out of the inner wall of my vagina!

I subconsciously almost called out my sister!

That's right, it shows that Xiao Ai is desperately in need of your penis to be inserted into sex with her.You can insert your penis into Xiao Ai's vagina now and thrust it back and forth.

I started having sex with my sister as Teacher Chen told me.

Teacher Chen, Teacher Xiaotian’s penis seems to have not been completely inserted yet!

A good question!

Teacher Chen explained,

Teacher Xiaotian’s penis is probably more than 6 inches long, while Xiaoai’s vagina should not be more than five inches deep. Therefore, Teacher Xiaotian’s penis can only go in so much. If you go deeper, it may be inserted into Xiaoai’s uterus and open the uterus.

Isn't this possible?

It’s not impossible, but today’s demonstration of sexual intercourse is not necessary to open a palace for Xiao Ai.Although the age is almost the same, opening the palace cannot be successful in one go.Xiao Ai, do you want to try sexual intercourse in your uterus?

OK!

My sister nodded and said

I think I can stand it.

Then Teacher Xiaotian, no matter how gentle you are, try slowly inserting it in!

I followed Teacher Chen's words like a puppet. I began to slowly insert my cock into my penis again, and my glans quickly hit a soft flesh. My sister screamed, and her lower body trembled slightly.

I knew that the glans had hit my sister's cervix.

I looked at my sister, wondering if I wanted to go deeper.My sister smiled at me and she blushed and said, "I'm fine, it's very comfortable, so let's not move, let me do it!"

My sister erected her lower body slightly, and I felt her glans fighting against the soft flesh.

Seeing this, Teacher Chen came over to lick and knead her sister's nipples and clitoris, trying to help her sister reduce the pain as much as possible during orgasm and open the uterus.

My sister's body began to get hot, and the soft flesh began to open slightly and wrap around my penis and loosen. Just as my sister rolled her eyes and climaxed due to the stimulation of many parts of her body, I seized the opportunity to push the soft flesh hard and entered my sister's uterus.

Wow!All of them are inserted!

Xiao Ai’s vagina is really amazing!If it were me, I wonder if it could be done!

Several girls chattered.

Teacher Xiaotian beautifully demonstrated the sexual intercourse inserted into the uterus. This is a very successful demonstration. Do students have any questions?

Teacher Chen, didn’t you say that anal can also be used for sexual intercourse?Can you ask them to demonstrate for us?

This class is about to end soon. Xiao Ai, can you demonstrate anal sex again next time?

My sister didn’t have time to pay attention to Teacher Chen at this time. My cock was already thick, and now my glans was kissing her uterus wall in her uterus.

This feeling is a bit unbearable for mature women who have already given birth, let alone a girl who has just had a short time of menstruation.

However, the bell rang without waiting for anyone to finish class.

OK, Li can pull out your penis.This is the end of this class. If you have any questions, you can communicate in the next class.

Me, I don't want to pull it out... I... got stuck...

The classroom was as silent as death.

What should I do?Wouldn't they be so connected in the future?

Oh my God, it’s not me who went up!

The girls below started chattering, some were gloating and some were worried.

Students are quiet, the men you can meet are basically unable to do this.Only when it is stuck can it prove that this is an excellent man. Excellent men are naturally qualified to occupy a uterus.And this is not impossible, the students are optimistic.If you have the chance to meet such an excellent man in the future, don’t panic even if you are stuck.

After that, Teacher Chen started massage near my sister's uterus and pressed the acupuncture points near my lumbar spine.

Strange to say.

After she pressed it a few times, I felt the bloating on my cock sluggishly, and my sister's cervix began to loosen.

After almost fifteen or sixteen minutes of massage, the glans and the cervix were finally separated.

I was thinking about making mistakes, so I might as well fuck me a few times and I found that my sister had fainted.

I don’t know if it’s because of the pain or something.

I felt a little reluctant to let go of my cock. At this moment, due to long erections and various physical and mental stimulation, I could no longer help ejaculate!

A stream of milky white and sticky semen ejaculated from the urethra of my glans. The moment the glans left the vaginal opening, my semen ejaculated at the vaginal opening like a faucet opening, and some of them ejaculated on her body.

Teacher Chen was also stunned for an accident. She didn't expect me to ejaculate so suddenly. The classmates also looked at me in a daze, as if I was a monster.

Teacher Chen, is this ejaculation?Why are there so many...

A female classmate asked in a low voice.

Yes, yes, this is ejaculation.

Teacher Chen didn't seem to have completely recovered, she said with some semen dipped in her hand

Because Teacher Xiaotian is excellent enough, he ejaculated so much.Ordinary men can only ejaculate as much semen as one spoon, but even if there is only such a little semen, they can produce many children.Students, if you just want to enjoy the joy of sexual intercourse and don’t want to get pregnant, you must take effective contraceptive measures. In the next class, Teacher Chen will tell the students how to use condoms.

I stood in front of the podium with great embarrassment until someone handed me a pack of tissues that I came to my senses.

I quickly wiped my cock clean, and then began to wipe the semen at the mouth of my sister's vagina, followed by the semen on her body.

My sister still didn't come back to her senses. I gently wiped her for her until she wiped it all clean. Then she closed her legs and put on her clothes again.

This extremely lustful sexual demonstration class ended like this. I unexpectedly discovered that my sister was so beautiful and sexy. At the same time, I was also glad that I could have sex with my sister. I even began to look forward to the next sexual demonstration class.

Yes, I look forward to having sex with my sister again, no, it’s sex!

Fuck!

I went home early because I had no classes in the afternoon.He quickly called Chen's mother and asked her how she did it.

Do you think I didn't give me any benefits?I gave that bitch our store seven free service cards before she was willing to help.

Well... No matter what, it's done.

But soon, the problem arose.

Or the problem is back home.

After all, that's my sister!

We are a family Ah!

My sister returned home calmly as usual, but when she saw me, her face suddenly turned red, and she went back to her room without saying anything and locked herself up.

I haven't come out except for eating.

I tried to communicate with my sister, but she didn't open the door for me no matter what.

So I can only give up.

But even at this moment, my psychology is still looking forward to the next demonstration class.

Each class in the university will have demonstration classes every afternoon.

So there may be a turning point tomorrow?

I thought to myself.

The next day, I came to the office early to wait class. I don’t know if it was to make Teacher Chen say a few good words in front of the principal or if I was looking forward to my sister again in order to perform better.

When I stepped into the classroom, I found that the female classmates were dressed neatly and sat waiting for my arrival, making me look like I was a star in a sales signing party.

Teacher Chen walked to the podium and said loudly about the classroom content of this class.

In today's class, we will learn two things: one is how to use condoms correctly, which is very important to you; the other is what common poses are there for sexual intercourse.In order to facilitate students to observe nearby, I would like to ask students to move their desks around.

So all the female students moved their desks around the classroom.This time, Teacher Chen still asked the students to volunteer, but it was obvious that no one was there.

Otherwise, it’s better to be Xiao Ai. After all, you have cooperated and have a better understanding.

I looked at my sister nervously, afraid that she would disagree, but I saw her face slightly red and nodded.Soon my sister and I walked to the open space in the middle of the classroom.

Now, you can take off your clothes now.

We quickly took off all the clothes we had on.

Although this is only the second time I have shown my naked body in front of so many female students, I am already used to it.

My sister seems to be more calmer than last time.

Now let’s learn how to use condoms correctly.

Teacher Chen said as she took out a small plastic bag from her clothes pocket. She gently tore open the bag, took out the things inside and showed them to the students and said, "Look, this is a condom."Does anyone know how to wear condoms?At this time, a female classmate stood up and said

Can I give it a try?

OK.

This classmate took the condom from Teacher Chen's hand and walked up to me. She put the opening of the condom on my glans and gently stroked it down.

Since my penis was already erect, she quickly put a condom on me.

Teacher Chen, am I doing it right?

Teacher Chen nodded and said

It is already great that you can do this. The teacher found that you work very actively and hard every time.However, before wearing a condom, the male penis should be fully moistened, otherwise the male will lose sexual desire due to pain.Xiao Ai, can you please give me some demonstrations for your classmates?

My sister nodded

OK

But I guess my sister won’t, either, after all, she has no...sexual experience before...?I suddenly remembered that I did it with my sister yesterday, but she didn’t even fall into love!?My mind went down in an instant.

I saw my sister walking up to me. She didn't bent over like Classmate Wang just now, but squatted down in front of me. She gently took off the condom for me, then opened her mouth and sucked it a few times, then spit it out and helped me put on the condom again.

Did the students see it?Xiao Ai’s demonstration just now was very good.Of course there are many ways to make your penis wet, and oral sex is just one of them.

A classmate asked

Teacher Chen, are there any other way to wear condoms?

Teacher Chen said, "You're good at asking, you can actually wear condoms for men.Will Xiao Ai?

The sister shook her head.

OK, let’s show you how to wear condoms with your mouth.

Teacher Chen also squatted down in front of me like her sister. She took off her condom, stuck out her tongue and licked my cock for a while, and then held it in her mouth and licked it back and forth.

Students, Teacher Xiaotian’s penis is now fully wet. Next, you should pay attention to how the teacher uses his mouth to help men wear condoms.

After saying that, Teacher Chen put the condom in his hand into his mouth, left the opening of the condom outside his mouth, pressed the opening on my glans, and swallowed the penis bit by bit. When she spit out my cock, the condom was already put on.

A burst of warm applause suddenly rang out in the class.

Next is to wear condom sex.Teacher Chen motioned me to lie on the floor of the classroom. Because the floor was very cold, the teacher suggested using the clothes that my sister and I took off to cushion underneath.

After I lay down, Teacher Chen nodded to my sister, but she didn't shy. She stepped over my body and squatted down slowly. She held the base of my penis with one hand, gently stroked it a few times, and reached the other hand between her legs to spread the labia and the larvae were separated, and the vaginal opening was put on my glans and sat down gently.

Maybe yesterday's incident still had some shadow on my sister. I could feel that my sister's movements were so slow, as if I were afraid of hurting me.

The whole class of female students gathered around at this time, and they watched seriously, while others were talking in a low voice.

Really went in.

Will wearing condoms affect your pleasure?

Teacher Chen obviously heard their comments

Of course, wearing condom sex will affect pleasure, but in order to ensure safety, wearing condom sex is still necessary.If you don’t want to have children, you must insist on letting him wear condoms when having sex with a man.

But you can also take birth control pills Ah!

The person who spoke was Wang.

It’s three parts poisonous, do you understand?

Teacher Chen said in a serious tone

Although the technology of birth control pills is now very developed, first of all, you will forget to take medicine regularly, and secondly, the price is too expensive.It’s better to use it to beautify and nourish the skin when ejaculate in the condom, or even drink it.

When Teacher Chen educated the students, my sister sat on my cock and looked very embarrassed. I don’t know if she wanted to get down or continue sitting.

Xiao Ai can come down.

Next is a demonstration of sexual postures.

After my sister got off me, Teacher Chen took off the condom that was put on my penis and said

Students, Xiao Ai has just left her menstruation, so she won’t get pregnant.So the next sexual demonstration does not require wearing condoms, so you can see the close contact between their sexual organs.You must observe carefully later and ask any questions.

At this time, the classmate Wang suddenly spoke.

Teacher Chen, why do you have to find Xiao Ai to be the partner of Teacher Xiaotian’s sexual intercourse?Don’t they have time at home?

I heard the sound like a bolt from the blue. If one person knows it, it means... almost the whole class knows it!And Teacher Chen clearly understands the situation!

Student Wang, you have to know that what we are doing now is a teaching demonstration, not really having sex.Since Teacher Xiaotian is Xiao Ai’s biological brother, their tacit cooperation is far beyond your reach.So the teacher asked him to be a demonstration opponent, Xiao Ai.If your brother is also excellent, the teacher doesn't mind letting you demonstrate.

Classmate Wang curled his lips. It seemed that she didn't have an older brother or her brother was not very good.

Then Teacher Chen can do it too!

Student Wang continued to say unwillingly.

It is not impossible for a teacher to be a partner of sex, but, first, Xiao Ai, a female in this family, must first obtain Xiao Ai’s consent, and second, the teacher also needs to be a tour guide, which is somewhat inconvenient.

Okay, please continue to demonstrate sexual intercourse for us.

Next, my sister and I demonstrated several sexual positions in front of more than 30 female classmates in the class, and even demonstrated anal sex in front of more than 30 female classmates.

To be honest, I don’t like anal sex. When I stuffed my cock into my sister’s anus, she was so painful that she trembled all over, which made me feel very distressed.

When the get out of class was about to end, Teacher Chen suddenly said

Classmates, let Teacher Xiaotian and his sister have a complete sex for us?

There was a burst of cheers in the classroom.

I looked at my sister, but she had already set up a pose and just waited for me to go up and fuck her.

I inserted my dick from behind. This time it was no longer a demonstration of how to use the dragonfly to flash water, but a real gun and live ammunition.

In order to increase the stimulation to my sister, I thrust my cock while stroking my sister's breasts, thighs and buttocks with both hands.

My sister soon got into the state. She couldn't help but scream loudly, and her vagina became more and more slippery. Psora water kept seeping out of the gaps between the genitals where our brother and sister overlapped, wetting the floor of the classroom.

Teacher Chen, what's going on with so much water flowing from Xiao Ai?

These are all vaginal fluids.When men and women experience pleasure in sex, vaginal fluid will flow out. Their function is to avoid damage to the vagina due to violent thrusting.Look, Xiao Ai is on the verge of orgasm.

At this moment, I suddenly felt my sister's vagina twitch violently, and a stream of vaginal fluid sprayed on my glans, and then my sister's delicate body kept trembling.

AHAH ...

My sister made a lewd voice that I had never heard before.

Students, please see, this is a typical orgasm characteristic!Xiao Ai is in orgasm now, this is the happiest moment for a woman.

Teacher Li Xiaotian’s performance today is really great. It would be even better if he could complete ejaculation in your sister’s body.

Before Teacher Chen finished speaking, I had already started ejaculation.

I, who already had the pleasure of being ruthless, could still bear it after listening to the stimulation of Teacher Chen's words.

I held my sister's legs tightly with both hands, and shot the hot semen into the depths of my sister's vagina as if I had fought my life.

I finally sprinted a few times and hugged my sister tightly and stopped moving.

Wow, the teacher ejaculated!

You see, he is sweating a lot!

The female classmates around him were talking about this.

Teacher Chen told me to pull out my penis and let my classmates watch the vagina that was ejaculated.

Look, these milky white liquids that flow out are men's semen.At that time, Teacher Xiaotian's father ejaculated in Teacher Xiaotian's mother's vagina, and combined with the eggs discharged from Teacher Xiaotian's mother's body, he gave birth to him.

Will Teacher Xiaotian ejaculate in his sister's vagina, and will he have a baby?

No, because Xiao Ai is still in the safe period.The teacher asked specifically before class~

Then the sister squatted down, let the semen flow out from her vagina, and got up and put on her clothes.

This long-awaited sexual demonstration class ended like this. I fucked my own sister's slutty pussy as I wished, and even ejaculated incest semen in her vagina.

Although we have had many physical contacts, and I even made my sister reach orgasm more than once, my several sexual intercourses or fuckings with my sister were all performed without exception in the presence of someone.

This has not changed our brother-sister relationship. At home, my brother is still my brother, and she is still my sister.

She didn't even want to communicate with me.

This situation made me very helpless and I could only look forward to the next sexual intercourse demonstration class.

On this day, I met Teacher Chen in advance. I politely asked when the class will start, but Teacher Chen said

Oh my God, Xiaotian, you are really physically strong.The previous teaching assistant had to take three days off for two classes, so the practical class was over.Next, it's time for us to take a theory class.

Think about it, they are weak at first, and they are incomparable to ordinary men, let alone those who have strengthened me.I was so bored that I was about to return home in disappointment, but was stopped by Teacher Chen.

You can wait in my office first, and the teacher will go to the classroom and come.

After saying that, Teacher Chen entered the next classroom from another door in her office. She soon came back, looking at me with a smile on her face and said

Xiaotian, this textbook was originally a self-study class. I just went to ask for the opinions of my classmates and said that I would give them a demonstration class for sex. The classmates seemed to like this kind of class very much.

I originally thought that Teacher Chen was going to assign classroom tasks and asked me to have sex with her in her office, but I didn't expect that she would ask her to cooperate with her to have a sex demonstration class. I was a little surprised, but there was nothing I could do. I was always a little uncomfortable with sex in front of so many people in class, and the pleasure was greatly reduced.

Teacher Chen took my hand and walked into the classroom next door. More than 30 female students in the class were looking forward to it.

Students, today, Teacher Xiaotian happened to have something to come to the office to find me. The teacher thought that this class was a self-study class, so he decided to give the students a demonstration class for their sex, which was the importance of caressing in sex.Since today's class was a temporary decision, I did not communicate with Xiao Ai, so the teacher had to give the demonstration in person.

The whole class of female students gave warm applause, as if they were interested in not who did it with me, but I was doing it.

So Teacher Chen and I took off our clothes together and stood naked on the podium.

Teacher Chen walked up to me, picked up one of my hands and put them on one of her breasts, and said to the whole class.

Sexual intercourse starts with caressing.Li can caress the teacher's breasts, by the way, that's it.

Then Teacher Chen signaled me to hold her in my arms. Her skin was smooth and delicate, and the beauty felt really good when she entered her arms.

Teacher Chen put his mouth over and started kissing me, explaining while kissing.

Kissing between men and women is an important prelude to sexual intercourse. You can put your tongue into the other person's mouth and suck each other's tongues.

As he said that, Teacher Chen put his tongue into my mouth and wrapped it with my tongue. I sucked her tongue, and at the same time stroked her delicate body with both hands. After a while, I put my tongue into her mouth again.

While sucking my tongue, Teacher Chen reached out to hold my cock and gently stroked it.

Wow!Li’s penis is so big!

Several classmates exclaimed.

Teacher Chen pulled out his tongue and said with a smile that this is the function of caress.But this is not enough, and further stimulation is needed to make it erect more fully.

After saying that, Teacher Chen squatted down, opened his mouth and took my glans and started to give me a blowjob.

She sucked my glans for a while, and then began to lick my cock with her tongue.

She licked it very seriously and almost all her cock was licked.

After licking her cock, she opened her mouth and swallowed my scrotum.

Teacher Chen’s oral sex skills are much better than those of her sister. My cock quickly became extremely erect under her licking.

Look,

Teacher Chen showed my cock to all the classmates

Teacher Xiaotian’s penis is now fully erected. You can come up and touch it to experience the hardness of the male penis after it is fully erected.

So all the female classmates gathered around, except for one person, that is my sister.

Her eyes were filled with anger or jealousy?

She...does she care about my brother very much?

Can't wait for me to think more, they touched my cock one by one. The naughty classmate Wang once again opened his mouth and took my glans in his mouth. This time she did it as she imitated Teacher Chen.

Okay, the students have already touched it just now. The male penis is very firm after full erection, which is ready for the next step of sexual intercourse.But women must also be fully moisturized.

Next, Teacher Chen used the clothes we took off to spread on the floor of the classroom. She asked me to lie on it, and then Teacher Chen lies on my body toward my lower body.

The posture the teacher uses now is called the Six Nine Style, where both men and women can caress each other's sexual organs.Teacher Xiaotian, you can try licking the teacher’s vagina now.

Soon, I forgot my sister.

After all, a white mature woman's buttocks are placed in front of me, so how can I have time to think about other things?

I stuck out my tongue and licked Teacher Chen's labia and vaginal opening.

Teacher Chen also opened his mouth and took my cock in his mouth and gave me a blowjob.

All the girls in the class surrounded me. Some were observing how Teacher Chen licked my cock, while others were watching how I licked my teacher's vagina.

Wow!Teacher Chen’s one is flowing out!

Xiaotian, can you put your tongue into the teacher's vagina?

I tried to stretch my tongue in, and the tip of my tongue was scraping the inner wall of my teacher's vagina.Some vaginal fluid flowed out of Teacher Chen's vagina, making my face and mouth full of vaginal fluid.

At this time, Teacher Chen spitted out my dick and told the classmates that the teacher's bottom was already fully wet, and Teacher Xiaotian's oral sex skills were also good. But Teacher Xiaotian, have you forgotten that you should lick the teacher's clitoris? The clitoris is the most sensitive sexual organ for women.

I started licking Teacher Chen's clitoris again.Teacher Chen quickly let out AhAh… moans.

Teacher Chen, you make AhAh cry, what does this mean?Is Teacher Chen looking forward to having sex with Li?

The teacher is already itchy inside, so the teacher will demonstrate sexual intercourse.

Teacher Chen got up and sat on my lower body. When she was about to use the vaginal opening to stroke my cock, Classmate Wang spoke again.

Teacher Chen, what would happen if the teacher and Li were forcibly interrupted at this time?

Teacher Chen's vaginal opening was pressed against my glans and said

Student Wang raised this question well.If you terminate the sex now, the teacher will be in trouble for a day.Once a woman's sexual desire is teased, she will especially want it.

After saying that, Teacher Chen sat down and his vagina swallowed my entire cock.

Teacher Chen's body was moving up and down, and his movements were getting faster and faster. Since she was sitting facing me, I could clearly see my cock coming in and out of her vagina.

AhAh… Teacher Chen couldn't help but let out an extremely lustful moan again

Students, please see, when a woman is moved, a man's penis will thrust in a woman's vagina and make the woman feel particularly comfortable.

Then Teacher Chen asked me to lie on her body, and her legs were spread wide and asked me to insert my dick into it and thrust it.

I thrust more than a hundred times in one breath, and she kept screaming.

The students around were stunned. Maybe they didn't expect Teacher Chen to be so lewd!

I thrust hard for a while again. Teacher Chen's moans were getting higher and higher, and the inner wall of the vagina kept twitching, and a stream of vaginal fluid was spraying out. I knew she was at orgasm.

So I slowed down the thrusting speed, and gradually Teacher Chen recovered from the climax.

She slowed down for a while and said

Students, Teacher Xiaotian just made me reach orgasm, but Teacher Xiaotian has not ejaculated yet, which is very bad for Teacher Xiaotian's health, so Li can continue to thrust until he ejaculated.

Teacher Chen changed her posture. She was on all sides, her snow-white and pink big butt raised her high towards me.

Xiaotian, you can insert it from behind.

I used both hands to separate Teacher Chen's legs, and fucked her cock in as soon as I thrust her cock.

Teacher Chen,

A classmate asked

Will you reach your second climax?

Teacher Chen answered while catering to my thrust

Many women do have a second orgasm, but the teacher has never experienced it in the past.

The female classmate said to me again

Teacher Xiaotian, you have to work hard!Let Teacher Chen reach orgasm again.

I smiled a little embarrassedly

I'll do my best.

All the female classmates applauded me, and some of them even shouted, Come on, Teacher Xiaotian!slogan.

What a weird and lewd scene?

During class, I fucked their teacher in front of a class student in the classroom, and they were still cheering me on?!

I quickly controlled my urge to ejaculate and fucked the teacher in this dog-fucking posture.

While fucking me, I lowered my body and kneaded Teacher Chen's breasts with both hands.

How does Teacher Chen feel now?

Oh, the teacher’s inside is a little itchy again. Teacher Xiaotian is a young man, it’s really good to be able to hold on for so long!

I received encouragement from Teacher Chen and started to thrust harder.After thrusting for hundreds of times, Teacher Chen's vagina twitched again.

AhAh… Xiaotian is so awesome… The teacher is at orgasm again… AhAhAh… No more… The teacher is not able…

Teacher Chen said with a rosy face

The teacher didn’t expect the second orgasm to come so violently, and the teacher’s body was about to fall apart...AhAhAh...Xiaotian!Cum quickly... Cum to the teacher...AhAh...

Teacher Chen's lustful look once again stimulated my nerves. I rubbed Teacher Chen's nipples hard, and quickly fucked the teacher's slutty pussy, screaming and ejaculated in the teacher's vagina.

Wow!Teacher Chen, Teacher Xiaotian has ejaculated a lot in you!

Teacher Chen squatted down and let the semen flow out from her vagina. She said with a blushing face.

The teacher was a little out of control just now, which made the students laugh.However, today's orgasm is the strongest orgasm the teacher has ever experienced in his life.Thank you for giving me such a great climax experience.

At this time, classmate Wang spoke

Teacher Chen, you are happy, but we are very uncomfortable!

Teacher Chen finally recovered from the climax, and she said in a serious voice

You are still virgins now, can’t you break your body easily?

Teacher Chen pondered for a moment and then said

Which students do you feel uncomfortable?If this is the case, let Teacher Xiaotian lick you with his tongue, so that it may feel better.

I looked at Teacher Chen with a little surprise. Does the teacher really want me to have oral sex for so many girls?

Xiaotian, you may have to work hard today.If you agree, will the teacher agree to have sex with you again?

Can I say bad?

Of course, I agreed readily.

So about twenty female classmates took off their skirts and panties. They sat on the chairs one by one, with their legs spread apart waiting for me to give them a blowjob.

I started with the first girl, licking the labia of these girls with my tongue, licking their clitoris with my tongue, and sometimes I put my tongue into their vaginas.

These female classmates are only fifteen or sixteen years old, and their vaginas are all pink and tender. Some have sparse pubic hair on the mons pubic pubicum, and some simply don’t have a single pubic hair. They are just white tigers.

I secretly compared their vaginas with my sister and Teacher Chen's. If it was just a blowjob, the vaginas of these little girls would have a better taste, but if it was a partner for sex, it would be more enjoyable for mature women like Teacher Chen to have sex.

When I was halfway through licking, the bell rang.

Teacher Chen said that those who want to go home can go home, and those who are willing to stay will be used as a make-up lesson.

There is a rule in college that when each student cannot complete the normal credits, he can add credits to make up for the tutoring, and up to five points.

Therefore, after Teacher Chen finished speaking, all the students stayed, and none of them were willing to go home.

Or, except for my sister.

She picked up her schoolbag without saying a word and left.

I finished oral sex for the remaining girls in one breath, and my tongue felt numb, as if it was not my own.However, seeing those girls satisfied, I felt an indescribable sense of pride.

At this time, Teacher Chen said

Are all the students satisfied?Is Teacher Xiaotian’s oral sex skills great?

Brother Xiaotian’s oral sex skills are really great.

These little girls have started to change their words to call them brother.

However, Li’s sexual intercourse skills may be even better!Do you think so?It is enough to make Teacher Chen reach orgasm twice.

Student Wang continued the conversation at this time.

Teacher Chen's face darkened

What does Student Wang mean when he said this?

Student Wang stretched out his tongue and said

Teacher Chen, I don’t mean to collide with the teacher, but I also want to have a one-time sex demonstration with Brother Xiaotian. I wonder if it’s OK?

Teacher Chen said firmly

No, you are still a virgin, how can you break your body like this?You must find a perfect man!

But Teacher Chen, is Brother Xiaotian not perfect enough?Besides, I am no longer a virgin, isn’t that okay?

Teacher Chen said

Even if you are no longer a virgin, you must obtain your mother's consent.

I thought to myself: I'm afraid no mother would agree to this kind of thing, right?

Give a teacher or fuck him casually.

Teacher Chen is clearly making things difficult for classmate Wang!

To be honest, although Wang is not the most beautiful among all the female students, she is also first-class. Moreover, her cute and naughty personality is exactly what I like, so it is really good to be able to fuck a beautiful girl like her.

Seeing that Teacher Chen's tone became more and more severe, she said in a loud voice without being outdone.

My mother has long ignored me, and I have the final say on my affairs.Does Teacher Chen like Brother Xiaotian, so he has reservations about us and will not let us taste it?

I looked at Teacher Chen with a little worried, thinking that the teacher was about to get angry.

Teacher Chen was indeed a little angry. Her face turned red and white, as if she was about to eat classmate Wang in one bite.

But the teacher is the teacher. She quickly calmed down her anger and said calmly

Since Mr. Wang insisted on having sex with Teacher Xiaotian, the teacher did not object, but you should ask the teacher to check whether your hymen is really broken.

Student Wang said

Just check it, can I still lie to you?

So Student Wang sat on a chair with his legs apart. Teacher Chen squatted in front of her, spreading her labia and nipped open, and looked carefully.

Student Wang’s hymen is indeed broken. Well, if Teacher Xiaotian wants to, you can have a one-time sex demonstration, but you must wear condoms and have sex.

Of course I wouldn't object. Although I had ejaculated once in Teacher Chen's vagina just now, I wouldn't refuse to have a beautiful girl like Mr. Wang let me fuck me.

At the suggestion of Teacher Chen, I lay down on the floor. Teacher Chen put on a condom for me with his own hands, and then told Student Wang that it was OK.

Classmate Wang rode on me openly and quickly put my cock into her pussy.

Classmate Wang’s vagina was much tighter than Teacher Chen’s even younger sister. Fortunately, when I gave her a blowjob, her vagina was already fully wet, and it was obvious that this was not the first time she had sex, so after the end of my cock was inserted, although it felt a little tight, she didn’t feel any discomfort.

But after she moved twice, I realized something was wrong.

Her vaginal opening is very elastic, and even after she has been stroked in, she will feel the tight clamp.

But there is a unique world inside, as if it can change at will according to my size.

Although it feels a little wide inside, it is filled with inexplicable attraction.

This is definitely a famous weapon, the fighter jet in the famous weapon contains pearls!

My wife in another world is Yangyan, and I thought I had picked up a treasure.

I didn’t expect that the jade clams and pearls I had only seen in the book actually made me meet!

This kind of vagina has a suitable vagina and also has the ability to respond to it. It can stretch and contract freely with the size of a man, and the structure is quite exquisite.

After passing the vagina and entering the interior, there is not much change in between, and the position of the flower center will not be too deep, unless the man's penis is too short, generally speaking, you can simply find the flower center.

When having sex, it will wrap the penis tightly, whether it is the thinner head or the lower back half, tightly with the same pressure.

Whether larger or smaller, it can be applied in appropriate tightness.

This vagina has excellent elasticity and elasticity.

But after some courtesy exchanges, the woman's flower heart will suddenly open, holding the man's head tightly and tightening the opening; on the other hand, the vagina will open and close like a clam shell, and perform super suction in it.

There are not five women with clam households in a thousand women, which can be regarded as rewarded by God.

When I had sex with classmate Wang, the other students were all watching around us.

Several other students were asking Mr. Wang what it felt like to have sex with a boy.

Student Wang shook his delicate body up and down while talking and laughing with her classmates.

It was about ten minutes later, and Mr. Wang began to feel a little overwhelmed.

Xiaotian, now you come to Wang’s top, Wang looks very tired.You can help her reach orgasm.

I turned over and pressed classmate Wang under my body, and my cock was thrusting hard. Soon, classmate Wang started to scream. Her whole body was trembling, and the climax seemed to be extremely strong. She kept screaming, but later it turned into a cry.

Teacher Chen said next to him that it’s okay, please continue to fuck her, she’s so happy.

Of course I know, but the problem is that I am almost squeezed out by this little girl's famous weapon.

For my face, I must first fuck her so hard that I dare not take it!

At this time, her legs began to sway, but I was not much better.

The strong sucking power and her glans wrapped around me as if she was not good, so I started to tremble all over. The two of them were sweating all over. Now that things have come to this point, whoever loosens his tense nerves will declare his failure in this game.

The pleasure accumulates infinitely in my mind, and I think if I fail in this tool, it will fail.

After relaxing, I began to focus on stimulating her sensitive points, which made me feel a little cushioned.

I fucked for a few more minutes, and Wang said

No, I can't stand it

Teacher Chen then asked me to get off her.

Fortunately, in the end I won her undeveloped famous weapon, otherwise she would be embarrassed in front of the whole class.

But in time, she grew up and didn't even need it. Maybe she had experienced several sexes and learned how to control the force and squirm in the cavity, and I might have become her subordinate.

All the classmates around me looked at me with admiration.

After all, being fucked by a man to orgasm is like a distant myth.

Many people are actually starting to get ready.

But Teacher Chen's next words made them afraid to act rashly.

Because she wanted to play in person.

Xiaotian, do you still want to ejaculate?

Teacher Chen asked me.

So what if you want to ejaculate?Student Wang has already done this.

Teacher Chen said to me with a smile

Of course, Mr. Wang is not good at it. If you want to ejaculate, the teacher will let you do it again.

I'm a little surprised

Teacher Chen has reached two orgasms just now. Can you do it again?

Teacher Chen laughed, she said

This is the difference between young women and girls!Student Wang is still young and his body has not yet matured, so he cannot bear too much stimulation, but the teacher is different. After the rest just now, the teacher has recovered. If you don’t believe it, you can insert it and try it.

Tiaodai, this lustful woman is really good for her excuse, but it’s okay.

Teacher Chen’s pussy is definitely not as good as a famous tool, but I still like the pleasure of fucking a mature woman very much.

Teacher Chen was not dressed at all, so he lay on the ground and spread his legs to wait for me to fuck her.

I leaned down and was about to fuck me, but the teacher stopped me.

Xiaotian, you take off the condom, the teacher doesn’t like to wear condoms and have sex!

Only then did I realize that I was too anxious, so I took off my condom and thrust my dick in.

It’s different for mature women. You don’t need to be pity Xiangxiyu, you can do whatever you want. Moreover, Teacher Chen’s age is similar to my mother’s. Fucking her makes her feel like she fucks her own mother, which feels very special.

Why do I think of my mother at this time?

I shook my head and put my mind back on the mature woman under me.

This time, Teacher Chen and I reached orgasm at about the same time.

After the climax, we realized that it was already very late and all the female classmates in the classroom had been exposed. I lay on Teacher Chen's naked body, gently stroked her breasts, thighs and buttocks, and my cock was still inserted into the teacher's vagina and couldn't bear to leave.

Xiaotian, you can come down.

Teacher Chen touched my hair lovely.

Teacher Chen, if I still want to have sex with the teacher, will the teacher agree?

Didn’t the teacher promise to give you another chance to have sex with the teacher?However, unless there is a sexual intercourse demonstration class in the future, the teacher will not have sex with his students casually.

I was a little disappointed, and Teacher Chen gently kissed my lips.

Silly kid, there will be no chance in the future!

Teacher Chen asked me to help her up. When she got up, my semen was still flowing in her vagina, but she didn't care. She didn't even wipe it off, so she put on her underwear and skirt, and then helped me put on her clothes.

When I got home, it was completely dark.And my sister was so angry that she didn't come out to have a meal.My sister couldn't even scream.Haha, I'm really jealous.

I didn't continue to please my sister like yesterday, but I rinse it briefly after eating and preparing to go to bed.

After all, I am now in multiple positions, and maybe when will there be a customer that I have to come to Chen's mother.

I slept very early, and I went to bed at about ten o'clock. I felt that after a while, I was awakened by the pleasure on my body.

As soon as I opened my eyes, I saw my sister naked on my bed, sucking and licking my nipples with her mouth, and stroking my cock back and forth with one hand.

Humph, do you know this is a punishment?This is a punishment for you to fuck those slutty bitches and never come to comfort your sister!

Seeing that I woke up, my sister immediately made an excuse for her actions.I didn't say anything, it would be suppose to say that it wasn't tired.But it seems to be quite enjoyable to serve in the middle of the night.

My sister leaned over to my head and started kissing me.

She straddled my body and rubbed my wet pussy back and forth against my rod. The two small and undeveloped breasts were squeezed between us so pity.

She stuck out her tongue and kissed me deeply.

Of course, I also hugged her small butt and thrust her lower body in line with her scratch.

We kissed this for a long time, and she hummed on me for a while, pulled the two of them away, and began to move under me.

The opened mouth looks so delicate and compact because of the undeveloped owner, but the enemies it faces are particularly hideous and huge compared to it.

In the absence of deep throats, women, such as sister, Chen's mother, or even Teacher Chen, were all ate half of their cock when they gave me oral sex, but for my sister, three inches was still too big. Or rather than not having the length, it would be better to say that my glans was too big, so my mouth grew to the limit and could only swallow my glans.

In this case, I had no expectations for this oral sex, but the turn came so quickly.

Because she could only swallow the glans with difficulty, her little tongue had nowhere to put it. When she stirred back and forth, it was particularly intense. It was very exciting to lightly tap or gently stroke my urethra from time to time.

Her upper and lower teeth were accurately stuck in the slightest part of my glans, intentionally orally gently biting my coronary groove. This kind of green and stimulating oral sex made me feel the strong pleasure I had never felt before.

But this pleasure is mixed with the slightest sense of foreign objects brought by the teeth, which makes me unable to stop.

With her left hand stroking, this kind of young oral sex seems to be good.

I enjoyed it for a while, and then I found that my sister was giving me a mouth while reaching out to her right hand and pulling her little pussy.

I motioned her to turn her lower body, and she stood up obediently and adjusted her position, and sat back on my head.

Because the height difference is still a bit, I can only raise the pillow to lick her pussy.

I used both hands to open the mouth of her pussy, and the pink little slut was displayed in front of me.

Because the tucking just now made the vagina moist long ago.

I took her vulva in one mouthful and began to lick her pussy back and forth with my tongue, and went deeper into it from time to time.

But as I licked, I suddenly realized that my sister's pussy seemed to be unusual.

At first I thought my sister had gynecological diseases, so I was so scared that I quickly opened it and observed carefully. My sister's vagina started to move inward from the entrance, not only had winding and complex channels and folds like an ordinary woman, but also had tiny pieces of flesh that almost occupied the entire surface of the vagina, just like a layer of sandpaper made of flesh growing in the vagina.

Needless to say, it must be a famous artifact, fragrant and jade teeth

For women with this famous instrument, there are granular objects on the front wall of their vagina like herring roe. When the tip of the man's glans touches this part, he will feel abnormally stimulating.

When a man thrusts, particles also stimulate the glans and produce strong pleasure.

If the posterior position is taken, the entrance is not only the tip of the glans, but the most sensitive parts, including the lace, will be rubbed by this rough particle, thus giving the male full stimulation.

With this discovery, I was naturally excited.

When I was in school, because there were so many people watching, the tension in my mind covered up the pleasure of losing my lower body, which made me not discover. Now that I have discovered it, I naturally have no reason to let it go.

Just when I wanted to change my position, the little beauty under me got up by herself, and she planned to ride on herself.

snort!Let you do it with other women!I want to punish you!I will sit down to death!

My sister is as arrogant as ever.(Although the arrogant and stingy have almost retired from the environment)

I cooperated with her to lean her upper body against the cushioned pillow, and my sister tried to sit down there without experience.

Although I held my cock, my sister seemed to be unable to find the entrance. Her glans and her pussy always kissed in a fleeting manner but could not enter.

She looked a little anxious, and I spoke to remind her

You help me and try it out.

My sister gave me a blank look, as if she was saying I knew.

Having said that, she still obediently as I said, holding the upper half of my cock with her little hand, supporting my belly with the other hand, finding the exact entrance, and began to sit down slowly.

Sure enough, as soon as I entered the door, I felt my glans in a tight passage, and there were many small bumps inside the passage stimulating my glans in all directions.

I couldn't help but exclaim, it felt really exciting.

The best thing is that my sister has not yet developed and her vagina is very short, which makes the stimulation of this sarcoma almost cover my entire penis.

My sister sat to the bottom with difficulty, but half of my dick was not inserted.

But the stimulating feeling of the upper end clamp is in a strong contrast with the stimulating feeling of the lower end, and it also has a different experience.

My sister began to shake her body up and down, but her cock was too long, so that every time she sat down, she would hit her cervix very firmly.

It is obvious that this feeling of pain and pleasure is not suitable for this undeveloped body.

Soon I felt my sister resisting, but because she was not feeling good about face.

I didn't want my sister to lose interest in sex from now on and became a living Bodhisattva, so I didn't ask her for advice, picked her up and put her under her. I tried several times and found the right position to make sure that every time I straightened my waist, I wouldn't stimulate her cervix very heavily.

This change was obviously very useful. My sister's frowning frown began to loosen up at the beginning, and she began to enjoy her brother's cultivation on her body with her eyes closed.

She put her legs on my thighs, grabbed the edge of the bed with both hands and enjoyed the fucking from my brother.

After all, there is a woman at home, so we both did not scream in agreement, but just breathed slightly in each other's ears to express our feelings.

Because I couldn't get into it all, there was no sound of having sex in the room, and there was only the sound of my sister's vaginal fluid.

It seemed as if the two were underground lovers who secretly tasted the forbidden fruit without telling them.

A young girl of this age cannot withstand high-intensity sex, which is why I prefer mature women.I decided to give her a quick orgasm to resolve the battle.

I originally wanted to lean down and lick her nipples, but my sister was too short and I couldn't reach it for a long time, so I changed my mind and rubbed her clitoris with one hand and pinched her nipples with the other.

In this way, I became a tool to serve her.

After all, it is physical stimulation for me, but it is not pleasant enough and I cannot open and close the fuck again and again.

On the contrary, my considerate benefited my sister very much.

The quick in and out and the constant stimulation in my hands made my sister immediately climax.

The vagina, which was already tight, instantly formed a strangling force, but I had not accumulated much pleasure to resist it easily.

I gradually slowed down, and my sister's trembling gradually stopped.

My sister slowly closed her eyes and felt the afterglow of orgasm.

Because I didn't ejaculate, there was no need to pull my sister up and take a shower. I picked her up and put it on the pillow, and licked her patiently.

She seemed to enjoy it, enjoying the cleaning with her eyes closed.

After I almost got clean, I got up and rushed to sweat on my body. When I came back, I found that my sister was asleep.

I lay beside her. But as soon as she lay down, she came over and hugged me tightly, leaning her little head against my chest.

I thought she was awake, but found that her breathing was still well-proportioned, which seemed to be a subconscious reaction.

I hugged her and fell asleep quickly.

When I woke up the next day, my sister was gone.After I had dinner, my sister was about to go out, so I said hello to see where to go to work today. Unexpectedly, my sister said something

She is still young, don't be too accommodating to her.Then he left.

Well, it looks like my sister knows it.From then on, my sister seemed to have been pestering me often, but every time she didn't fuck me, she could only say that she was still addicted to food.
