To be a prisoner of my brother’s sexual desires.


Chapter 1

Mie Aoyama (Senior in high school. Eighteen years old)

Ever since I was an elementary school student, I’ve hated that mysterious area between my legs.

The wet area had two walls of flesh that looked wrinkled and unappealing, especially the offensive red color that showed up in all its disgustingness.

Even though it’s the most mysterious part of my body, I can’t stand it, it’s filthy! I often spread my thighs when no one else is around, and then I smell a disgusting odor coming up to my nose, it’s really repulsive. That’s one of the reasons why I hate it.

Even after going to the toilet, and after drying up the residual pee, the area remains moist. So it gathers sweat, dirt, etc., which means it always gives off an obscene odor.

Just a whiff of this stench creates an unbearable feeling of uncleanliness. As ugly as it looked, I lost myself in the pleasure of masturbation. Every time I swore that this was the last time I would masturbate, but in the end I couldn’t help but break the vow myself. And in doing so, I hated it more than ever, making it impossible for me to resist its evil temptation to masturbate incessantly.

Sometimes I would look at my naked body before or after taking a shower. I stand straight up, close my two tightly together and inhale to scrunch up my abdomen, the mysterious zone is completely hidden at this time, and I just revel in my self-appreciation, standing straight up really straight from head to toe, it’s very fascinating.

I always thought I was a mermaid at this point, but as soon as I saw my not-so-good-looking face, my mood dropped to the bottom with it.

“This that’s a mermaid, it’s simply a mongrel.”

I forget which book it was that said that a man’s sex organ – just one look at it will make him feel an unbearable urge. And if you get “fucked” by him, you’ll need it for the rest of your life. But when I saw my dad’s penis in the family bath, it was hanging like a deflated parachute, and I couldn’t get aroused at all.

For as long as I’ve known, I’ve never been able to stand the ugly look of my mystery zone, and I truly loathe it from the bottom of my heart. I just didn’t expect it to be exciting when I inadvertently touched it.

I used to do some weird things to my mystery zone. For example, one time I took a red mike pen and painted it big red, and ended up getting yelled at by my mom for staining my underwear because all that red seeped through!

Childish behavior like this not only made me feel my heart rise and fall, but it also turned me on so much that my heart was beating non-stop, and mucus was oozing out of my hole down there, and that kind of pleasure was so pleasurable that it’s hard to describe it with ink. Another time, I use the pointed handle of the comb into the woman’s most mysterious and sensitive hole, I endure the pain, it will be inserted into the more inside place and keep pumping. After a while, after pulling out the pointed handle, there will be drops of blood flowing out from the hole, this situation, even more let me excited straight gasp, long time can’t self.

Although I was punishing myself for the mysterious zone that I abhorred, the excitement that resulted from this self-abuse was undeniably a rather mysterious pleasure as well.

However, I don’t know why I have such an extremely contradictory personality. I am having sex with two men at the same time, and although they bring me nothing but sexual pleasure, I use them to do things that I cannot do on my own in order to punish my mysterious zone.

Of course, my parents didn’t know about my strange sexual fetish and the fact that I was having a physical relationship with two men at the same time, but of course, I hid it very well. Even when I came home from school, I didn’t go through the room where my parents lived, but went straight to my own room on the second floor of another building.

That night around eleven o’clock, my two partners, Kiyoshi and Nishida, quietly came to my room on the second floor. In fact, it was because I went to Nishida-kun’s apartment on my way home from school during the day, and the two of them had sex alone without Kiyoshi-kun’s knowledge.

I made Nishida-kun a little unhappy because I insisted on having Nishida-kun fuck my genitals, rubbing them, manipulating them, and licking them. After all that, I was also tired and I don’t know how to put it, but anyway, my genitals were hot and swollen, and I always felt like there was something rubbing against the second side of my abdomen. I couldn’t straighten my back, and I felt like something was wrong with my whole body, but I didn’t want Kiyosaku-kun to get suspicious, so I tried to cater to him as much as I could.

Because Nishida-kun sarcastically said, “Mie-san, you’re in good spirits today yo……..” And so on this type of cold words that Seishaku-kun can’t hear the strings to mock me.

Just like usual, Qing Shaku Jun he first pressed on top of me, it was the first time I felt that a man was so heavy, so I told him that I was tired today, I was a bit not too comfortable, I might not be able to fully cooperate, as long as he likes it, do whatever he wants. As soon as he said that, Qing Shaku-kun hugged me passionately and kissed me passionately.

“Tonight, Mie is different! Full of charm, cute and marvelous.”

While he was whispering in my ear, and to make me happy, he kept sucking on my breasts, biting my ears and rubbing them. And from time to time, he picked at my clit with his hand. He caressed me passionately. But because of the swelling and pain in my genitals, no matter how hard Kiyoshi-kun fucked me, it was as if I was paralyzed and had no feeling.

On the contrary, I became a piece of cloth under his body, my whole body shaking as he squeezed and rubbed me, as if he was having sex all by himself. It was as if he was having sex all by himself. And he would cum on me in no time. Next, Nishida-kun holds me and fucks me from the side, he always uses this kind of side sex position, and from time to time he stimulates my clitoris with his fingers, and this way, I finally get some pleasure.

It took twice as long as usual, but finally I reached my climax, and I turned back over and spread my feet wide, reveling in the pleasure of my orgasm and letting out a moan. At that moment, my mind went blank and I was unconscious. All I could think of was “yes”, and I didn’t even know when Kiyosaku-kun and Nishida-kun had left.

The next morning, I had a terrible headache, and the joints of my body were very sore. Especially the sex organ is even more strange, although it is not hot and not swollen, but there are some white secretions flowed out, it feels like back to the old days like that. In the evening, after I recovered my spirit, I remembered what happened last night, and I was still a bit excited to hold back.

After taking a shower and finding a front to watch TV while thinking, that’s when Nishida-kun arrived.

“Ms. Mie, last night was great, do you remember how many times we fucked in total?”

And I listened quietly.

“Well …. Tonight at my apartment, you coming? There’s a new character yo …….”

After that, he left with a mysterious smile. At seven o’clock, I couldn’t stand it any longer, and I left the house under the pretext of returning my friend’s notebook. Then I felt my heart rising and falling like a wave, and like a sleepwalker, I unknowingly went in the direction of Nishida-kun’s apartment, I really–

Chapter II

At Nishida-kun’s apartment, I saw three faces expecting me, including the newcomer’s, and when I saw the so-called newcomer’s, the young man took me by surprise. Because his name was Junichi Kubo, he lived on the busy side of the street, his family ran a bar, and his mother used to work at the lounge when she was in love with my father, something that no one in the neighborhood didn’t know.

After she married someone else, Junichi-kun’s stepfather financed the bar. When the bar opened, my parents knew about it. As time went by, the story became a big deal, and my mother used to criticize my father for it, which led to a lot of arguments between the two of them, but no matter how much they argued, they didn’t do anything too bad.

In fact, Jun’ichi-kun, the child father had with that lover, in fact, we didn’t interact like other relatives, and we didn’t see each other for any reason, but it’s true that we are brother and sister. Although he inherited his mother’s beauty, I think he looks more like his father, and there’s no mistaking the fact that he’s his father’s son.

I knew about it at the time, but it made me a little constrained based on the relationship between the three of us, my dad, his lover and my mom.

Now that it’s blatantly obvious that we’ve met, and even if I wanted to treat him the way I treat others, it wouldn’t change the fact that we’re siblings. Regardless, I still felt uncomfortable and had an inexplicable feeling. But the fact that he was really handsome ignited some wonderfully undesirable desires in me.

Junichi-kun and I met at the apartment Nishida was looking at. Before we could call ourselves brothers and sisters, we had a broad relationship. And although the grudges of the previous generation were complicated, we improved our mutual hostility and developed some feelings for each other due to our sexual relationship, for which I gradually distanced myself from Nishida-kun and Kiyoshi-kun, and stepped into Jun’ichi-kun’s world.

Along the river there is a city known as a busy street where Junichi-kun’s family lives in a two-story jacketed storefront, but he has to live alone in a small apartment by the river in the name of studying hard.

He would come from home to live alone in this small apartment only when he had to study hard, and sometimes he would spend the night here, and sometimes he would go home.

He, like a few of his peers, didn’t like living in a place where his mom could see and control him. That’s why he lives here, a bit of a recluse.

One day, I received an invitation from Jun’ichi-kun, who told me that this room was quite private.

He was alone at ordinary times, and the nights were mysteriously quiet and undisturbed. He also wanted me to go there no matter what.

Filled with curiosity, I accepted his invitation, and that evening took the opportunity of this visit to him to meet him here alone.

I thought it must be a quiet and bookish house because it was Junichi’s study place, but contrary to what I thought, it was a luxurious house with a special design, a small but well-equipped kitchen, and a living room with some beautiful and expensive furniture. The living room was furnished with beautiful and expensive furniture, and the kitchen was fully equipped, so it was convenient to live here all year round. Although the south side was facing the sun-drenched river, it was far away from the shore, so you didn’t have to worry about being seen no matter what you were doing in the room.

Couldn’t ask for a better, more private home.

Before we came here, Junichi-kun had told me that when we came here, we were going to have fun and do what we wanted to do, just like any other gay lover, and we really had a great time that day.

With the relationship of brother and sister, there is no need for us to be polite and break down the constraints, and we have nothing to hide from each other. We can talk freely about family matters, private matters, and personal matters.

Junichi-kun has some strange interests. He likes to play with each other’s sex organs more than having sex normally. Because when we were together, we spent most of our time playing with each other’s genitals, and of course we had intercourse and sex. But sometimes, it’s almost always Jun’ichi-kun himself who gets satisfied by ejaculating first, while I don’t feel any pleasure at all.

“We’re brother and sister. Isn’t it weird to do this?” If I

When he said that, Junichi-kun rode on top of me without taking it seriously, and pulled out his “man’s dick” while shoving it into my private part.

“Not surprising at all, what parents can do, there is no law that says siblings can’t do ah this”.

It was always such a casual thing to say and then keep kissing me, hugging me and caressing my body.

In the beginning, we decided to get together once or twice a week, and only in the evenings. Gradually, however, we were not only together on Sundays, but even later on, we simply skipped school and stayed in that secret house all day long.

The house is heated, so you don’t have to worry about getting cold even if you’re naked.

Junichi-kun has a picture of an athlete’s physique, strong and big, with even more pubic hair on his lower body, and to top it all off, he has a fully grown-up-like baby.

When he’s not wearing clothes, you can still see the old wound on his right abdomen where he had an appendix opened on one side For me, who had never played with each other’s sex organs naked with a man in a brightly lit room, or had sex in various and sundry positions, I was really embarrassed when I first started to do these things in Junichi-kun’s house.

The real reason is that naked, my skin is dark, my breasts are pointy and my body is not very voluptuous. I’m dry and flat, but I’m especially fat from my stomach to my thighs. Compared to Junichi-kun, who has a slender and muscular body, I really paled in comparison.

Junichi-kun’s sex organ is particularly large and hard from any angle, and at all times [it] gives off the feeling of being a male.

The front of the glans was shaped like a shiitake mushroom and glistened with a bright flesh color, always coming hard when it throbbed to the beat. Compared to his genitals, my ugly genitals, which were always wet and inconspicuous, made people think of it as a filthy piece of trash to be thrown away. But despite what I thought, this ugly thing was unexpectedly loved by men, and I often found it unbelievable that every man who knew me wanted to fuck me.

Junichi-kun was no exception. He always sucked on it and licked my ugly sex organ filled with the stench of urine as if it were a sumptuous delicacy. From time to time, he even buried his face between my legs and sniffed the stench with his nose.

I reciprocate him with the same action. Usually I would grab Junichi-kun’s penis in my hand and then touch his pubic hair with my nose or gently take it in my mouth before pulling it up.

And of course oral sex by taking the glans in his mouth and sucking on it with one suck, or licking it and rubbing it with the tip of his tongue. Finally, he would use his hand to keep rubbing his penis, which was full of saliva, to make him cum. While the action was going on, especially at the moment before launching, Jun’ichi-kun always buried his face in his palms, starting from his chest, the flesh on his abdomen and legs trembled uncontrollably, and his whole body trembled and moaned as if he was being bitten by tens of thousands of worms.

I’m also excited as hell. Although having sex with only one person doesn’t give me an orgasm, I can have one if I finger my clit.

I told Junichi-kun to do that during intercourse, and sometimes we even climaxed at the same time. Sometimes we compete with each other to see who can climax first.

Once Junichi-kun made me lie down on a low table, exposing the lower half of my sex, and after spreading my legs, he used something that made me feel pain, and inserted it into my private hole with just one gulp. Before long, I felt like peeing.

Finally I couldn’t help but pee with a swoosh. As I felt the hard object being pumped up along with my pee, I hurriedly rolled over onto my back, at which point the strange and slender looking object fell as I did so.

At this point when Junichi-kun was scrambling to find a place to wipe the pee-wet east side, I handed him the inner glow that I had taken off to wipe the wet area.

“Why, what’s that?” I asked him so.

Junichi-kun then showed me the long green dongyou that looked like a rubber hose.

He said, “This is the stem of the water lily in the pool.”

Turns out he took the withered stem from the watery ground and inserted it into my sex. And it could be inserted as far as it would go. When pee came out of the tube, he hurried to catch it in his mouth, and just as he was about to drink it, I rolled over and got up, so he got pee all over the place.

“I don’t know what you’re doing to roll over and get up, but you’re planning on drinking piss really dirty.”

After I said that, I turned my face away and Junichi-kun smiled at me and said, “But since it’s my sister’s pee, how can it be dirty? It won’t be at all ……..”

“It’s annoying …. Really nasty …….. Then next time I’ll drink your pee too, yo!”

Junichi-kun said he wanted to do it again, but this time he prepared a towel, a basin and a spoon, and then asked me to lie on my back and spread my legs like earlier. He took Suiren’s penis and pushed it down towards the peeing place as he had done earlier.

It still hurt a little and it wasn’t comfortable at all. When that tube was inserted as far as it would go, I got the feeling that I wanted to pee. So I quickly said to Junichi-kun, “Is it okay? I want to pee again.”

He scrambled to organize himself.

“You can pee all you want, no problem?”

Junichi-kun he answered me while slowly inserting the tube inside a lot more again, at this point I had a little pleasure with pain. So the urine overflowed from the outside of the tube and onto the towel that was padded under my ass beforehand, and for a split second the towel got a little wet.

On the other hand, Jun’ichi-kun was sucking in the urine coming out of the water lily pads with the appearance of enjoying some kind of delicacy. Eventually the urine stopped flowing out, and his bladder stopped swelling like a deflated balloon.

“The tube is too tiny.” Junichi-kun said something like that.

Although I had also been sucking his cock. I drank his urine several times, but the warm, salty urine was not good at all. Once I even used the rubber tube Junichi-kun bought from the drugstore to insert it through the glans of his penis, and even though it caused a fracture, it was still inserted, and it was inserted quite deeply. At that time, there was warm urine coming out, and it was not leaking a drop of it, so I drank it through the tube.

This kind of behavior between the two of us is probably called “sexual perversion”! But I think it’s an unexpected turn-on for me.

Chapter III

Shortly afterward, Junichi bought a so-called “medicine that makes you strong after injection” from someone and injected me with it. He injected the syringe directly into my clitoris. The drug was usually injected into my wrist, but Junichi made it his business to inject it into my clitoris. After a while, I felt hot around my waist, and although I felt comfortable, I did not have the expected feeling of sexual excitement in my trance.

Junichi-kun, who knows my fetish, sometimes uses a test glass tube with hot water filled inside and capped. Taking it and shoving it hard into the entrance of my private parts, he makes me climax by hand.

But even though he inserted a glass test tube and then pulled it out, then licked my labia with his mouth, and finally inserted his already hard and erect penis, all of which he had arranged so painstakingly in order to make me reach my climax, I didn’t seem to have any pleasure coming out of me in the end. o Although it was true that being able to have sex with Jun’ichi-kun was one of the things that attracted me to him, it was probably because I had developed a love affair with my real brother, Jun’ichi-kun. I think it’s because I’m in love with my real brother, Junichi.

And I’m quite happy that he’s looking at me as his sexual partner. However, to Junichi-kun, maybe I’m just an object for him to vent his sexual desires.

During this period of time when I was indulging in sex with Junichi-kun, every three nights or two, Seishaku-kun and Nishida-kun would also quietly come to my room on the second floor.

Recently we have become more and more daring. One by one, they often sneak into my room, and then the three of them sleep in the same bed until after sunrise, so that the three of them can have sex again after sunrise.

The so-called pleasure. Although it is necessary for the two of them to take turns to do it twice each in order to generate pleasure. Of course, there are times when they can’t feel pleasure even if they do it twice each, but generally speaking, they can feel pleasure.

Kiyosaku-kun touched my clitoris with his fingers, while Nishida-kun inserted a glass test tube into my hole and masturbated me continuously in this manner. The feeling at that moment was really awesome.

If they masturbated me even harder, they would always moan unconsciously. Although I had sex with three men without interruption, I had no signs of pregnancy, and I don’t think any girl my age would have sex as often as I did.

When I talked to a good friend about this, she said, “When you get your period, you ovulate with the bleeding, and when the egg is in the uterus, you can get pregnant if you have sex and let the sperm in.”

That means when the period comes, if you don’t have sex, you can’t get pregnant. But I think the opposite of her. Once I asked Junichi-kun what he thought about this.

“What that’s what your friend said?” That’s funny, does she even understand! What comes out during menstruation is an egg that’s already necrotic, so you can’t get pregnant despite having sex while you’re menstruating.

“Oh! I see.”

“So you understand? That’s why there’s a so-called safe period.”

He explained it to me like this.

“Meitei have you ever seen what sperm looks like.”

“Yeah what?”

“Sperm worms la! Next time I’ll show you, I’ll bring the family microscope here to show you. And Mie you probably haven’t seen your own eggs! During menstruation …..”

“No, and there’s such a thing as looking at your own eggs ……….”

“Have you never seen an egg that’s already necrotic?”

“No.”

“Just pay attention when you’re on your period.”

“Hey! How big is it?”

“Hmmm! Very tiny, almost so tiny that it’s almost invisible, a few millimeters in diameter, a really extremely tiny creature.”

“How can you see clearly in that case?”

“Next time you get your period, Mie, we’ll come and take a look.”

Junichi-kun he planned excitedly.

“I’ve been trying out a big invention lately, yo!”

“What was the invention, come on:come on ……..”

“Well! It’s the use of computers to do the birth of artificial babies.”

It’s as surprising an idea as the creation of test-tube babies, and saying something like that makes it seem like half of it is a joke, but then again, looking at the seriousness on his face, this kind of topic is borderline irrelevant anyway.

Change the subject!

I had doubts in my mind from time to time because my periods were not going well, and from time to time I pondered over various possible causes, and since a large amount of leucorrhoea had been falling out a lot lately, I thought that there must be something wrong with some part of the uterus for this to happen. A white, sticky substance like sour fermented material was coming out of it, and it was so abundant that it was staining my underwear.

I often have a yellow, wet layer in my underwear, which is very unpleasant. At first, I thought it was semen that had been ejaculated into my underwear during intercourse, but after intercourse, it flowed back out, but the disgusting odor did not smell like semen.

In my stomach, there are strange spasms in the vicinity of my uterus, as if my whole abdomen is heavy, and sometimes I can even feel it spasming! When I have coitus that is a little more intense or when I have intercourse for a longer period of time than usual, although it can make me feel excited, the pain after the pleasure is getting worse and worse.

Nonetheless I still made an appointment with Junichi-kun to work on the eggs together the next time I have my period, so I also let him know in advance about the scheduled date that I had calculated.

Before his next menstrual period, Junichi was researching various methods to obtain eggs that survived from the ovaries to the onset of menstruation… and he was really working hard on it! It’s true.

One of them, Jun’ichi-kun, wanted me to lie down on a low table in his study and then spread my legs to their maximum arc so that he could scrutinize and study them.

He inserted his finger one moment, then used a ruler to measure how deep the hole was, and even explored the innermost structure with the tip of his finger to find out what it was like.

A few days later, Jun’ichi-kun took the semen he had collected after masturbating and put it under the microscope for me to see. Surprisingly, in the white and bright semen, there were infinite spermatozoa like an army of thousands of horses, which were swimming towards the front like silver, and through the microscope, I could clearly see this scene, which was really thrilling.

“Wow! That’s a lot of oh ….”

“Just insert my thing, penis, and all of this will run down to your belly, yo!”

“Really? Such a shame in that case …….. First time I’ve seen one of these ……..”

When Kiyoshaku-kun, Nishida-kun, and Jun’ichi-kun took turns fucking me, as long as one of them did it twice, then a total of six times a portion of spermatozoa would go into my stomach. I wondered how many thousands of spermatozoa could be hidden in a single drop of semen when each ejaculation was only a drop or two.

How many spermatozoa will actually swim into my uterus after so much sex six or even seven or eight times?

One time Junichi-kun he prepared a kettle for keeping water warm. He collected the semen that came out of me after I kept masturbating him for about four hours and ejaculated about five times.

He said the thermos has the same temperature as the body, so the semen can be kept for many days until it stinks.

The semen he ejaculated, although the first and the third time he ejaculated more, but on the fifth time, the semen was a little bit dry and solid, and stayed on the glans as the glans stretched and shook inside and outside, as if it was hard to gasp for air. In the end, just one drop came out apologetically.

Lying on my back toward the bright light, I felt Junichi-kun insert the thick glass test tube into my private opening.

This glass tube is hollow and can be inserted into the pubic area to go right to the innermost part. And he could also see inside like a diving scope in the sea. Junichi-kun he confidently explained.

“Wow …….. You can really see the very inside!”

Then he pressed his face between my spread legs again.

“Yes, it’s a bottomless pit yeah,”

I was also infected, and I got excited in a strange way. Afterwards, the two of them embraced each other under the low table with the electric heat lamp, and played with each other’s genitals fiercely, igniting their burning desire. That day, I also stripped off my clothes and got under the blanket, and then I put my feet under the low table to keep myself warm, and then I cuddled with the completely naked Junichi-kun, and after kissing, masturbating, and performing oral sex, Junichi-kun inserted his already-erect penis into my cavern.

And so unfolded another coitus.

I would be on top and raise my ass up to allow his brother to enter and fuck me from behind, or I would have side sex from the side, or I would even have coitus by jiggling up and down in a seated position. Making love in this series of strange coitus positions made me fall in love with Junichi-kun.

The fact that we are really brother and sister is not allowed to fall in love with each other, and of course marriage is even less permitted, but despite this, we have been indulging in sex and trying weird sexual things. What’s going on here?

He had already ejaculated five times in a row, but this time he didn’t ejaculate easily. But with the excitement of the stimulation, his penis was getting bigger and harder to the point of almost bursting, and for that reason Junichi-kun also felt pain.

“Junichi-kun doesn’t want to cum yet?”

“Uh… A little more …. Meiji …. What about you?”

“Uhh! Don’t mind me, you shoot!”

At that time, I attached my mouth to Junichi-kun’s ear and told him while sighing.

“We siblings …. I can’t believe we’re doing this …………”

“Hmmm. :…. Hmmm …………”

Suddenly Junichi-kun, he hugged me even harder and accelerated the force on his waist, pushing in fiercely. I said again.

“We’re brother and sister” …. We’re brother and sister! Isn’t it …………”

I was gasping for air when another incredible thing happened.

Suddenly a breathless pleasure surged up, that this big hard rod tickled without wringing between in and out, making one feel that the whole lower abdomen was paralyzed, at this point I couldn’t hold back and arched up, moaning and spasming at the same time, even my buttocks kept on trembling.

Then I don’t know how much time passed, but when my consciousness naturally returned, I felt what happened when Junichi-kun pulled himself up.

Even though Junichi-kun had withdrawn his manhood, I still felt that the weight of my entire body was still on top of me, and I was really tired.

When he fingered my naked torso from below, all I saw was his fast asleep face, propped up with drowsy eyelids, and then he kissed me with his mouth, and with a satisfied smile.

This is the first time I’ve really climaxed in so many coitus actions with Junichi-kun, could it be that my body really can’t leave Junichi-kun? I’m afraid that’s exactly what he’s thinking as a brother!
