Big sister, second sister and I have a passionate collision, and it must be loud (adult novel adapted from anime)

There are three children in my family: my eldest sister, my second sister and me. My two elder sisters are one and two years older than me respectively. My sisters were all very cute and pretty, with smooth, white and tender skin. So when I was a child, I often masturbated thinking about their naked bodies. Sometimes I masturbated four or five times a day and didn't feel anything.

At that time, there was only one air conditioner in our home. It was summer vacation, my parents went to work, my second sister went to learn piano, and my eldest sister and I went to sleep in the air-conditioned room during our nap. I get excited every time before going to bed, because I always secretly reach my hand into the quilt to touch my elder sister when she is asleep. At first I was very nervous and only dared to touch her thighs, and my hands would tremble. But after touching her several times, she didn't wake up, and I became bolder and moved up gradually. I didn't touch my sister's vagina directly, but touched her breasts!

My eldest sister was fifteen years old at that time and was attending a girls' school. She had a plump body. I faced her and rubbed her breasts with my hands. They felt so soft, but I couldn't feel her nipples. It might be because she was wearing a bra!

When I saw that my elder sister didn't move at all after making a "hmm" sound, I became bolder. I reached out my hand to her vulva and started rubbing it. It felt bumpy and soft. I was sweating even though I was using the air conditioner. I was so nervous!

Because my elder sister was wearing loose shorts, I thought I would put my hand in through the crotch of her thighs so as not to wake her up. Just as I was about to put my hand inside her pants, I suddenly found that my elder sister was looking at me with her eyes open! I pulled my hand back in fright, but to my surprise, my elder sister actually reached her hand into my quilt and moved it towards my crotch!

I was sweating all over and staring at the ceiling motionlessly. My sister's hand finally stopped on my penis (through my shorts of course). My penis was throbbing with excitement, and she grabbed it lightly, and I ejaculated violently with excitement. I didn't get soft after ejaculation, my sister looked at my face and slowly reached into my underwear, my erection became even harder, but I felt that as soon as my penis touched her tender and soft hand, she pulled it out immediately. I think it might be because of the touch of the sticky and slippery semen!

Afterwards we both acted as if nothing had happened, but every time we took a nap, I would reach under the quilt into her panties, playing with her sparse pubic hair, rubbing her clitoris, and even inserting my fingers into her wet and slippery vagina. My sister's vagina will bounce outward at first and then slowly contract. The soft and warm feeling is so wonderful, and there is also a constant wriggling feeling, which is amazing! My sister closed her eyes, her whole body trembled sometimes, and her lips were tightly closed, as if she was afraid of making any sound!

Then my sister would reach out and hold my penis. At this time, I would take my underwear off to my ankles, and my sister would hold my penis, watch the changes on my face and rub it for me. She wrapped her slender and smooth hands around my glans, rubbed the lower edge of it, and stroked it back and forth until the numbness and soreness became unbearable any longer. I then ejaculated violently and quickly wiped it clean with tissue paper.

Summer tutoring started soon after and we didn’t continue. Until one day, I couldn't bear thinking about my sister's tender body anymore, so I ran to my eldest sister's room at night when my parents were asleep. At that time, my eldest sister was studying to prepare for next year's joint entrance examination.

I walked into the room and looked into her eyes. She lay down on the bed without saying anything. I was very excited and immediately took off her clothes and started to caress her from head to toe. My elder sister closed her eyes and seemed very comfortable. I had touched her for so long, but I had never kissed my sister. At this time, I pressed my lips on my sister's lips, which felt very moist and warm. I pressed them like this for a long time.

I boldly used my tongue to push open my sister's mouth. My sister didn't resist, so I licked everywhere inside her mouth, feeling the wet touch. Then I began to reach my hand between my sister's labia and stroke her clitoris. For the first time, she screamed obviously because of pleasure, which made me even more excited. Fortunately, the sound was not loud, otherwise it would have been terrible if we were discovered!

Then I started to rub my sister's cute pink nipples, feeling them gradually getting bigger and more elastic. I suddenly had the urge to suck on those nipples, so I put them in my mouth and teased them gently with my tongue.

My sister has always been very obedient and let me touch and play with her, while I carefully observed her snow-white and well-proportioned naked body.

I kept stimulating my sister's clitoris, gently scratching it with my fingers and licking it with my tongue. My sister's body became very hot, and even felt a little pink. The inside of her vagina became very wet, slippery, and hot. It kept contracting, and a little milky white, sticky and slippery liquid flowed out. I couldn't stand it, so I took off my pants and my penis immediately popped out.

Seeing my sister closing her eyes, opening her mouth and breathing slightly... I had lost all my rationality at the time, and no longer cared about moral principles. I spread open my sister's white thighs, held my penis and inserted it into her vagina. My sister was startled, she opened her eyes and looked at me, and nervously tried to push me away, but I pressed her down hard to prevent her from resisting, and even covered her mouth with my mouth, for fear that she would scream!

But unexpectedly, my sister looked at my face and not only did not resist anymore, but she hugged me and actively put her tender tongue into my mouth and entangled with me. I was very excited, my penis became bigger and harder, and when I pushed hard into my sister's vagina, I felt something soft. I thought it should be the hymen?

I pushed forward with great force, easily penetrating the soft membrane. I felt my sister holding me tightly, her face pressed against my cheek, and her breathing became rapid. After that I started to move back and forth according to the instruction in the A book, but my sister's warm and soft vagina wrapped tightly around my penis, and the stimulation was too strong. After less than fifty thrusts, I forcefully ejaculated inside my sister's vagina. My mind was blank at that moment, and I felt so tired and comfortable after the release.

I didn't pull out my penis after I ejaculated, and my sister continued to kiss me. I didn't leave my sister's body until my penis gradually softened. I originally wanted to do it again, but I seemed to hear a noise outside the door. I became very nervous and quickly went back to my room. My sister was worrying about the light red bloodstains on the sheets.

I was very worried later. When I had sex with my eldest sister for the first time, I heard what seemed to be a noise outside the door. What if it was my mother? Well, that's impossible. If it was my mother, she would definitely come in to stop it. But what if it was dad?

Well, if it were, we would be hung up and beaten! I thought about it and decided that if there really was someone there, it must be my second sister. I was very, very worried that this taboo would be discovered.

I was thinking at the time: If I ask her directly, what if it’s not the answer? Wouldn’t that give the truth away? If it really is her, what should I do? This matter has bothered me for a long time. I think my second sister is only fourteen years old. What would she think if she saw my penis inserted in my eldest sister's vagina?

One day, when my eldest sister was at cram school and my parents were at a wedding, leaving my second sister and I alone at home, I finally plucked up the courage to run to her room. I stammered in front of her, not knowing how to ask her.

At that time, my second sister was wearing a loose white T-shirt and I forgot what color shorts she was wearing. I only remember that I could almost see her pair of snow-white breasts through the collar. I was so focused on looking at her that I forgot what to ask her. I just tried to find some irrelevant questions to ask, and then pretended to see what she was writing and leaned in to the right angle to feast my eyes.

My second sister is prettier than my eldest sister. My eldest sister is cute with smooth and delicate skin; while my second sister has a pair of beautiful legs and bright eyes that seem to be able to speak. I looked through her collar and because she was bending with her head down, I could almost see her pink areola. I was so excited that I suddenly thought of my eldest sister's naked body and wanted to touch my second sister's tender breasts immediately!

As I spoke, I imagined the feeling of rubbing against my second sister's flawless white breasts, and my lower body began to swell as I thought about it.

Oh my god! I can't forget the nervous feeling I had when my second sister suddenly looked up at my crotch. However, my second sister did not react in surprise. Instead, she acted even bolder than my eldest sister. She didn't even hesitate. In a blink of an eye, she held the tent erected by my penis with both hands.

I don't know why my second sister, who was only fourteen years old, didn't get startled or show any other reactions that I expected. Instead, I was shocked by her bold move and stepped back quickly. At this time, my second sister told me that she saw me and my eldest sister doing something that shouldn’t be done, and she really wanted to see my penis. My whole face turned red at that time.

She smiled, pulled me to the edge of the bed, and slowly took off my pants. My red and hot penis immediately popped out. I felt dizzy and lay on my second sister's bed, while my second sister opened her eyes wide and watched carefully from all angles.

She used her index finger and thumb to bounce my penis back and forth, and suddenly she held my penis with her right hand. I felt the comfortable feeling of her soft palm gently stroking it, and for a moment I couldn't bear the numbness, and I ejaculated with the bounce. The second sister was startled and tried to avoid it, but some of it had already shot onto her face.

At this moment, I heard a sound from the entrance and I was stunned. I quickly jumped up and put on my pants. My second sister was even more nervous. She quickly walked to the bathroom, closed the door and cleaned off the semen. I pretended to walk out as if nothing had happened. It turned out that my eldest sister was coming home from tutoring.

I didn't go to look for my eldest or second sister that day, of course because I was afraid that my parents would come home at any time. In the end, my parents didn't come back until I fell asleep.

(2)

Ever since my second sister showed curiosity about me, I had a feeling that I might have a physical relationship with her. In the following days, I always wanted to see my second sister's naked body. Whenever I saw her, I would imagine that she was not wearing any clothes: her snow-white breasts were slightly raised with pink nipples, and her flawless beautiful legs ended with a raised mons pubis covered with fine pubic hair, with a light pink slit in the middle, slowly leaking out sparkling mucus.

Finally one night, I saw my parents went to bed early, so I ran to my second sister's room. The second sister was already asleep at that time. She was wearing shorts, revealing her snow-white, slender thighs. She was covered with a quilt and sleeping facing the wall. Her exposed thighs were white and smooth, and the tenderness made me want to take a bite. I thought: Last time my second sister directly held my penis, so it should be okay for me to touch her thigh. I thought so, but I was still very nervous before touching her, and my whole face was burning.

I finally plucked up the courage and put my palms on the inside of my second sister's thighs. Maybe my hands were too hot, my second sister was shocked and turned around. When she saw it was me, she didn't say anything, but just asked me to get on the bed quickly.

I went to bed as I was told, and I was surprised that my second sister was very active. She asked me to take off my pants. My penis was already very hard and when I took off my pants, it popped out. She seemed to find this action very interesting and she grabbed my penis and made it bounce again. This time, my second sister was bolder than last time. She used both hands and opened her big watery eyes to carefully observe my penis. My penis was turned over and over by her soft little hands, and it became a little unbearable, so I quickly asked her to stop.

Then I asked my second sister to take off her clothes as well. I had never seen her body before, and I especially wanted to see how her vagina was different from my eldest sister's. My second sister didn't object and took off her clothes generously. I was really excited watching her take off her clothes one by one. I pulled her down and lay down, and touched her all over.

I feel that my second sister is much more sensitive than my eldest sister. I didn't touch her for long before her eyes became blurry. When my hand reached her labia, she almost pressed her entire vagina against my hand. When my fingers touched her clitoris, my second sister had already opened her mouth and was gasping for breath.

My second sister’s vagina is really like a steamed bun just out of the oven, white and fragrant, with only a few barely noticeable strands of tender hair on the mons pubis. I flipped open my labia and what came into view was a beautiful bright red. I gently inserted a finger into the vagina and the whole vagina became wet and sticky. I gently licked her clitoris with my tongue. My second sister seemed to have reached the limit of her tolerance. She gasped heavily and her abdomen kept twisting. She reached out and pressed my hand to prevent me from moving. I had evil thoughts and pulled her hand away, constantly stimulating her clitoris, while also holding her already enlarged pink nipple in my mouth and rubbing it with my tongue.

My second sister twisted her body more and more violently. She crossed her thighs and clamped my hands tightly. After a while, she finally hugged me and shook, and then she orgasmed.

Then, without asking for my second sister's consent, I directly inserted my penis into her vagina. Although this should not happen, my second sister did not refuse. After insertion, my penis felt so tight and warm, and there was an intermittent wriggling sensation, it was really comfortable! I was thinking: If my first time was in my second sister's vagina instead of my eldest sister's, I might not be able to bear the feeling and ejaculate without even moving.

I started to want to thrust in and out. My second sister's vagina was very tight. Fortunately, my second sister really secreted a lot of vaginal fluid, so I could push in smoothly. I pushed hard to break my second sister's hymen, but apart from frowning slightly, she was still breathing with her red mouth open, sweating, and still looked very comfortable.

I began to thrust in and out of my second sister's vagina. Looking at her dazed face, I couldn't help but put my tongue into her mouth and entangled it with her smooth tongue. My hands were rubbing my second sister's soft body. My second sister kept making "hmm...hmm..." sounds. The sounds were very nice and made me feel more urgently needed. I also tried harder to satisfy her!

I increased my speed and penetrated my second sister's pussy fiercely. Her vagina kept contracting and gave me strong stimulation, but I tried my best to endure the numbness and gave her the strongest thrust. We went on like this for about three or four minutes. Suddenly, my second sister pressed her soft breasts against me, hugged me tightly and shivered. Some hot liquid seemed to secrete out of her vagina. My glans felt hot and I could no longer bear it, so I spurted out with a tremor. The soft and slippery vaginal wall of my second sister still held my penis tightly and squirmed, pressing my penis tightly to squeeze out every drop of semen.

I have never felt so comfortable. After ejaculation, I felt dizzy all over. I lay on my second sister's body and couldn't move. My penis remained hard in her vagina for a long time. The pleasure usually disappears quickly after ejaculation, but after having sex with my second sister, I felt the sour and numb feeling remained there and did not dissipate quickly. It was so comfortable! The second sister tilted her head, closed her eyes, opened her moist little mouth and gasped, with saliva even flowing from the corners of her mouth.

We maintained this position for a long time before my penis softened. I pulled it out of my second sister's vagina, and she stood up and knelt to help me clean it. Unexpectedly, as soon as she knelt up, white semen, her own mucus and a little blood slowly flowed down her thighs. We were shocked and afraid that it would get on the sheets, so we quickly went to the bathroom to wash it off before it flowed onto the bed.

The second sister went to the bathroom without putting on pants. Unexpectedly, when she went to the bathroom, the eldest sister also went to the bathroom after finishing her homework. We saw someone outside and stood there.

The eldest sister looked at us, looked at the naked second sister, looked at the white semen and transparent mucus that had flowed down to her calves, smiled at us, leaned forward and let the second sister go into the bathroom to clean up, and I quickly went back to my room to sleep.

After I returned to my room that night, I couldn't sleep and felt a little guilty. I was afraid to let my parents know that I had physical relations with my sisters, but the feeling of rubbing my body against my sisters' and their vaginas was really exciting to me. And the thought that we were of the same blood made my cheeks hot and my penis swell.

When I go to school, I will still keep thinking about it. I want to touch my sister's smooth naked body, knead her soft breasts, insert my penis into her wet vagina, feel the feeling of being tightly surrounded, and entangled with her and kiss each other.

Sometimes I would have sex with my eldest sister first, and after she was completely satisfied, I would sneak into my second sister's bedroom, enjoy her beautiful body, and pick her little heart. Because he has already ejaculated once, the sensitivity of the penis has decreased, and he must thrust for a long time (sometimes more than an hour) before he can ejaculate and satisfy his sexual desire. To be fair, sometimes I would have sex with my second sister for half an hour, and then go to my eldest sister's bed and rape her for more than an hour.

Although I raped them so violently, the two sisters never complained or objected, but loved me even more. They hugged me tightly during sex, allowing me to caress their fair and tender bodies, lick and suck their breasts and vaginas, and use various postures to penetrate and rape their little ones.

Their menstrual periods are different, which is a good thing for me because I can have sex every night without interruption. But my sisters were afraid that I would get pregnant if I ejaculated inside them, so they always asked me to pull out my penis as soon as I felt I was about to ejaculate.

I always felt sorry for doing this, and later they finally agreed to let me ejaculate in her mouth. I felt more stimulated because on the one hand, I was very excited when I saw my sister's cute face with sweat on it, her red and wet mouth holding my penis, and her eyes blinking to watch my reaction... On the other hand, my penis was beating in her warm mouth, and my sister's dexterous tongue was rubbing my glans. Every time I couldn't stand the constant sour and numb feeling, and in the end I could only ejaculate my semen deeply into my sister's throat.

We found that this was a good way because the bed would not get dirty, and my sisters would not have to use tissues to wipe it after drinking my semen. However, they were less able to enjoy the beauty of my cock ejaculating inside their clitoris, so during their safe menstrual period, I would ejaculate directly into my sisters' vaginas. I was so happy looking at my sister's hazy eyes, her open mouth gasping for breath, her vagina constantly contracting and sucking my cock...
