I accidentally fucked my girlfriend's sister (family incest adult novel)

I was 25 years old that year. My girlfriend was 3 years younger than me. We had been dating for 4 years. In terms of sexual cooperation, she was the girl I missed the most among all the girls I have dated. His body proportions and temper left me speechless. He had a pretty face and was once invited to be a guest star in a magazine model. Later, because his family opposed it and he himself didn't like it very much, he didn't enter this industry

My girlfriend lives in downtown Tainan because her family is taking care of her business. She lives alone in a three-story villa in Yanxing, a suburb. Because she lives alone, we often run around the house naked in the bathroom, stairwell, cloakroom, and balcony. We make love casually. One time, I put her on the washing machine while it was drying. Not only did she have continuous orgasms, she even peed. Later I learned that it was squirting.

Once, it was his grandmother's birthday and relatives and friends came from all over to gather to celebrate the old lady's birthday. His sister, who was three years older than him, was married and also came back with her child. His sister was as good-looking as his girlfriend but more feminine. There was a touch of spirit in her eyes. She was the type who enjoyed getting close to women, both men and women. His brother-in-law was unable to come along because he was abroad on business. His girlfriend's father booked several rooms at the Cambridge Hotel in downtown Tainan for relatives and friends to stay. His sister said that she hadn't talked to his girlfriend for a long time and wanted to stay at home with her so that the two sisters could have a good chat. So I drove his sister and the child back to the suburbs. As soon as we entered the house, we chatted in the living room. His sister's 34-year-old child went crazy, running upstairs and downstairs, laughing and shouting, and asked me to play with her. His sister saw that the situation was not right, so she said to your friend, "You take a rest first, I'll put the child to sleep and then go find you to chat." So we went up to my girlfriend's room on the third floor to take a shower and watch TV. There are two rooms on the second floor, one for his parents and the other for his grandmother. There are two rooms on the third floor, one for my girlfriend and the other for her brother. Her brother is in the army, so his sister lives in her brother's room on the third floor, opposite to us.

When we took a shower and lay on the bed watching TV, my hands started to become restless. My girlfriend is very sensitive. She would blush and her heart would beat fast if I teased her a little. Every time I wanted, she never refused. I gently touched her breasts and licked them a few times, and they became soft. Especially her vagina became moist after a few touches. Not to mention that when I licked her clitoris, it made her even more crazy. We were familiar with each other's bodies and we made love to our heart's content every time. We had done it 7 times a day at most, and 34 times was not uncommon. We rarely do anal sex, but it's not as comfortable as described in pornographic literature. We've tried every possible position, including the vibrator, massager, and exposure. We're not interested in anything else. She said we're a perfect match. To be honest, under his handsome appearance, he always wears a long skirt, has long flowing hair, speaks softly, and is a little shy. You can't imagine that our sex life is so rich.

Catalyzed by a small amount of alcohol, I have long wanted to have a big fight with my girlfriend. I know that my girlfriend is also looking forward to it. But she has been tossed around by her sister and that cute nephew for so long. It's rare that I get back to the room and take a shower. What are you waiting for? My penis has long been hard and swollen. My girlfriend holds my penis mischievously and says: Let's take the oral temperature first. My girlfriend gave my penis a nickname called "thermometer". Sometimes we take oral temperature, breast temperature, armpit temperature, anal temperature... After that, she pursed her lips, wet her lips with her tongue, opened her mouth and took my penis into her mouth, and swallowed it hard to the bottom. Then, she tightened her mouth and slowly pulled out the penis to the end of the glans, and then used the tip of her tongue to tease the urethra, and then swallowed it to the bottom. Slowly retreat to the glans, and then use her tongue and teeth to circle around the ridges of the glans, and repeat this over and over again. This is my favorite trick

We often discuss each other's likes and dislikes about sex, so we never get tired of it... When I was immersed in endless pleasure, I suddenly remembered that his sister would come over to chat with my girlfriend, so I didn't want to waste any more time, so I was busy taking off his pajamas. His girlfriend hesitated and said: Don't take it all off, his sister is coming over, I think so anyway, she was wearing a one-piece blouse, so you can't see anything underneath, so I helped my girlfriend to put her on the bed, and used my mouth to pick up the hem of the blouse, and began to move my tongue around her lower abdomen, gently biting the small waistband of her underwear with my teeth, and slowly took off her underwear with my mouth and licked wherever I took it off. As my girlfriend gasped softly, I knew it was about to fail;

After the panties left my girlfriend's ankles, I started licking from her ankles all the way up. When I licked to the back of her thighs, I gently spread her white, slender and well-proportioned thighs apart. As I expected, the paradise under the sad and fragrant grass was already covered with sweet rain. I hadn't even touched her genitals, but it was already wet. When the tip of my tongue slowly licked my girlfriend's vulva, she twisted her buttocks in anticipation. I deliberately licked from the inside of the thigh to the groin, back and forth, deliberately skipping the vulva. Finally, my girlfriend couldn't bear it anymore and held my head with her hands to guide it to the middle area. She lifted her buttocks up and muttered: You are bad, you are bad, you are bad... I hate you, I hate you...

In order to give him immediate satisfaction, I extended my nimble tongue to cover his entire genitals, and then used the tip of my tongue to sweep hard from the anus, perineum, vaginal opening to the clitoris. I only heard my girlfriend's satisfied "Oh~~" and her moaning began from then on.

My tongue was moving back and forth inside and outside her vagina, sometimes lightly, sometimes heavily, making her moan incessantly. After about ten minutes, my girlfriend's legs began to tremble, her abdomen was stiff, and her chin was lifted up. I knew she had an orgasm. After a tremor, he held my head and guided it upwards. Following her gestures, I stood up and stood in front of him, hugging her body tightly. Our tongues were swirling in each other's mouths. After stopping, he moved his mouth to my ear and whispered, "Come in~ Okay?"

At this time, I couldn't hold it back any longer, but I deliberately said, "You lead the way." My girlfriend looked at me shyly. She knew I liked her to hold my penis with her hand and guide it to her vagina. That kind of lewd action would make me very excited. Under his guidance, my glans finally touched her soft and slightly warm vagina. With the expectation of each other, my glans slowly inserted into my girlfriend's vagina. The initial touch was the most wonderful combination. At the same time, I heard each other's satisfied sighs. After the delicate and delicate foreplay, the second stage of lovemaking is about to start a fierce collision in order to reach the peak of climax~~~

At this moment, I could no longer hold back the surging desire. I could hear the wriggling and eager contraction of my girlfriend's vagina on my fingertips, revealing the message of desire. I turned my girlfriend's back to me and guided her to arch her buttocks towards me. I slowly pushed the penis head, which was suppressing its silent roar, into the warm "wet paradise" with the expectant vaginal fluid from her vagina...

At this moment, her sister was still describing in detail the matter of her mother-in-law buying a diamond ring... Because I was lying on my side with my legs together, I could feel my penis getting particularly hard. I was afraid that if I moved too much, her sister would notice it, so I didn't dare to move. I just let the swollen and hard penis stand straight and stiff in my girlfriend's vagina. Before long, my girlfriend didn't care whether her sister would notice anything unusual and began to twist her hips restlessly in the hope of getting more pleasure. So I also started to thrust slowly and unceremoniously, and my girlfriend also stopped responding to what her sister said, and instead moaned and panted softly...

Experienced people know that the final stage of lovemaking is the intense and violent pumping until the point of ejaculation. Only then is it thorough and enjoyable. How can the pumping like this, without any big movements, satisfy two bodies conquered by sexual desire? I don't know how long it took, but gradually her sister, either because she noticed something was wrong or was really tired, could no longer hear her talking, replaced by even and regular breathing.

I peered through my girlfriend's body and observed her tightly closed eyes. I could still see her eyeballs rolling slightly under her eyelids and her eyelashes twitching involuntarily. I suspected that "she was pretending to sleep to avoid embarrassment"... I thought that since she was so considerate, I would not let her down. So I had evil thoughts in my mind and pulled my penis out of my girlfriend's body. I turned her body over and made her lie flat. Then I spread her legs and turned her over. I stood between her legs and motioned for her to hold my penis with her hand and guide it to the entrance of her vagina. I liked this kind of action and reinserted the glans into the woman's extremely eager vagina.

This time I have no scruples. I have been holding it back for the whole night. Now no one can stop our determination to make love happily... At the beginning, I just thrusted at a slightly faster frequency. After 56 minutes of wanton indulgence, the pleasure of ejaculation gradually filled my mind. I could no longer pretend to be gentle. I bent my waist and raised my knees to lengthen the stroke and force of the thrusts. Under my full force, my girlfriend could no longer hold back her lewd calls. Her low moans turned into wild and carefree shouts. At this critical moment, we seemed to have forgotten that how could her sister, who shared the same quilt with us, be unaware in the middle of the December night?

Finally, the semen that could not be held back came out like a wild horse in the sound of "pa pa" from the connection between my girlfriend's reproductive organs and my full sprint. I hugged my girlfriend's body tightly, and my lower body was still bent, pushing my penis deep into the depths of my girlfriend's vagina. I immersed my hard penis in my girlfriend's vagina and enjoyed the rhythm of the strong contraction of her vagina after the orgasm. I was reluctant to withdraw...

I leaned on my girlfriend's body, panting. Our bodies pressed together, feeling each other's sensitivity after the passion. Every nerve was transmitting the message of pleasure and the rhythm of satisfaction. I don't know how long it took. In a trance, I turned over and lay down, still hugging my girlfriend's body. This lying down opened another prelude to what happened next...

After I lay down, I habitually lay on my right side. Now I was in the middle, my girlfriend was on the left, and his sister was on my right. After the passion, my girlfriend and I fell asleep quickly. I mentioned before that I always have the habit of hugging something when I sleep. If there is someone, I hug that person, and if there is no one, I hug a pillow. I fell into a deep sleep. After tossing and turning for a while, I was in a daze. The soft body I hugged felt itchy on my cheek, so I subconsciously smoothed his hair and kissed her on the face, then hugged her again and continued to sleep.

The body I held tightly in my arms was twisting restlessly. In the half-asleep and half-awake state, my hands began to restlessly grope on the familiar body. In fact, such actions did not have any sexual impulses, but were just subconscious intimate caresses. My hands first covered her breasts, but I felt the bra was in the way, so I reached behind my girlfriend and unhooked her bra with a pinch and a release. My girlfriend often said that I have a pair of skillful hands, and I am quite proud of this. Haha, the full and plump breasts in my hands always make men intoxicated by the full feeling. In fact, I did not intend to go any further in my dream, so I fell asleep again holding the breasts... I don’t know how long it took, my hand unconsciously touched my girlfriend’s private parts again, but I couldn’t feel anything through her underwear, so I used my fingers to peel off the bottom of her underwear and directly touched her vagina, only to feel it was wet and slippery. At this moment, my whole body suddenly froze, and my fingers stopped moving... My girlfriend was clearly naked in the bra just now, so how come she was wearing a bra and underwear now? Before this, I had been closing my eyes with an uneasy mood. I opened my eyes slightly with a guilty conscience... Suddenly, a chill quickly ran from the soles of my feet to my forehead...

Oh my god! The person I was hugging turned out to be my girlfriend's sister. She woke up all of a sudden, but she didn't know how to end it. All her movements froze. The funny thing was that my finger was still inserted in her sister's vagina. With the help of the wedding lights, I glared at her sister. She still had her eyes tightly closed, and I could even tell that she was closing them a little too tightly. Suddenly, I realized that her sister had the mentality of an ostrich. With her eyes closed, she could be said to be asleep. She had no idea what was happening. If I also closed my eyes, it could be said that I had hugged the wrong person in my sleep.

So just as my vigilance was gone, my lust arose again. Since that was the case, I just went with the flow and resumed my fingers' activities. I first slowly stirred the shallow part of her vagina, then smeared the love fluid secreted from her vagina on her clitoris, and then rubbed it gently and rhythmically. At first, her legs were not wide enough and she was still wearing panties, which made it a little difficult for my fingers. I withdrew my hand that was caressing her clitoris without hesitation, hooked my fingers around the waistband of her panties and pulled them down. His sister was able to lift her hips even when she was sleeping with her eyes closed, so I could easily take off her underwear. When my naughty fingers returned to her private parts filled with love juice, I felt that the "movement space" was much larger. It turned out that his sister automatically spread her legs a lot, which made it easier for my hands to move.

After I teased his sister's clitoris for a while, I tried to use my middle finger to slowly insert the deep part of his sister's vagina. While I inserted my finger deeply into her vagina, her sister actually raised her lower body and tried her best to cater to me. What surprised me even more was that the amount of vaginal fluid secreted by my girlfriend's sister was really amazing. It had made my whole hand wet. I tried to insert two fingers into her vagina to stir it, and unexpectedly found that there was a bulge on the upper edge of her sister's vagina. It was not very obvious but I could feel it. When my fingers were stroking the bulge in her sister's vagina, her sister suddenly hugged me tightly, but her lower body almost left the bed, arched up and trembled... and her mouth made oh~oh~oh~ sounds, and I knew that her sister had orgasmed.

I held his sister tightly in my arms and bent down to kiss her neck, earlobes and forehead. We stayed like this for 12 minutes. Slowly, his sister's body relaxed, and the strength of her hands holding me also obviously decreased a lot. I sealed her lips with my mouth, and her sister immediately stretched out her soft and slippery tongue to stir in my mouth. When we reluctantly separated our French kiss, I deliberately called my girlfriend's name softly in his ear and said: Huihui, are you comfortable? My girlfriend's sister still closed her eyes but nodded gently.

I called her that on purpose to avoid embarrassment to both of us. After all this tossing and turning, I was already burning with desire, and my hard penis was shaking on her belly; her sister silently reached out and held my erect penis in her hand, and used the prostate secreted by my glans to gently play with the urethra with her thumb. I turned over and pressed her sister under me. In addition to spreading her legs, what surprised me was that her sister held my glans in her hand and guided me to the position of her vaginal opening. When my glans entered her vagina, her sister's hand immediately moved to my buttocks and applied force towards herself. With such encouragement and expectations, how could I let her down? Although our desire overwhelmed our rationality, I still had some concerns about my girlfriend who was sleeping next to me. I didn't dare to thrust too violently. Besides, the object was her sister, and I couldn't estimate what the consequences would be if my girlfriend saw us. Besides, I love my girlfriend and she cares about me very much.

In such a dilemma, I almost wanted to stop... and her sister's hands pressing on my hips became more and more eager, and I knew her sister was about to reach the critical moment again and I couldn't pretend anymore, so I whispered in her sister's ear: Let's go outside, okay? Her sister didn't seem to understand for a moment and paused, then nodded after a while.

The interesting thing is that her sister still had her eyes closed. I turned over and got out of bed without even putting on my clothes, walking out with my penis erect to the small living room outside. After a while, I heard a rustling sound, and her sister's figure finally appeared in front of me in the dark. I hugged her sister and there was no need to calibrate in the dark. Our mouths soon entangled again and we greedily sucked each other. After a passionate kiss, her sister motioned for me to sit down, so I sat down on the sofa. She squatted between my legs and gently held my penis with her hand and stroked it for a while. She used her hand to put her long hair behind her neck. It is the most charming action for a woman to do before giving a man a blowjob. Then she lowered her head and licked the urethra on the glans with the tip of her tongue. Then she slowly put the entire glans into her mouth, and her tongue was still constantly turning it over in her mouth. After a while of swallowing, her sister continued to lick my scrotum and perineum, and at the same time I could hardly help moaning.

Maybe it was because it was our second time making love or maybe it was because the effect of alcohol was slow, I kept pumping wildly for a long time until I heard her sister repeating: No more, no more, I can’t stand it anymore… I’m so numb… Finally, I couldn’t suppress the urge to ejaculate and in the last few times I deliberately added the weight of my body to the strong thrusts, I couldn’t bear it any longer and the glans was so swollen that her sister could feel that I was about to ejaculate~ Her sister hugged my waist and almost shouted: Cum inside, cum inside….

While ejaculating, I pressed my penis tightly against the deepest part of her sister's vagina. My penis was throbbing with pleasure in her vagina. Unexpectedly, the contraction in her sister's vagina was even stronger than that in my girlfriend's. It was as strong as when I ejaculated in my girlfriend's mouth. She sucked my glans hard in accordance with the rhythm of my ejaculation. It was as pleasurable as ejaculating in her girlfriend's mouth. After ejaculating, I almost lay on her sister.

After a while, her sister gently pushed my body to signal me to stand up. When I pulled my half-hard penis out of her sister's body, she asked me to sit down again, covered my vagina with one hand, squatted down, and took my glans in her mouth and sucked it gently. After a long time, in order to respond to her tenderness, I didn't care that there was still semen in her mouth, and I kissed her passionately again...
