Fucked my girlfriend's sister (family incest adult novel)

I am 25 years old and my girlfriend is 3 years younger than me. We have been dating for 4 years. In terms of sexual cooperation, she is the girl I miss the most among all the girls I have dated. Her body proportions and temper are beyond words. She has a pretty face and was once invited to be a guest model for a magazine. Later, she did not continue to invest in this industry because her family opposed it and she herself did not like it very much.

My girlfriend lives in Tainan City most of the time because her family is taking care of the business. She lives in a three-story villa in the suburbs (Yanxing). Because she lives alone most of the time, we often run around the house naked, in the bathroom, stairwell, cloakroom, balcony... We make love very casually. Once, I put her on the washing machine while it was drying, and she had continuous orgasms, and she even peed (I later learned that it was squirting)...

A while ago, her grandmother had a birthday, and relatives and friends came from all over to gather to celebrate the old lady's birthday. Her sister (3 years older than her and married) also came back with her children. Her sister is as beautiful as her girlfriend. She is very pretty, with a great figure, more mature and feminine, and long flowing hair... There is a hint of spirit in her eyes. She is the kind of woman who is happy to be close to everyone, with both temperament and beauty. Her husband went on a business trip to the mainland for two months for company business and was unable to come with them.

My girlfriend's dad generously booked a room at the Cambridge Hotel in downtown Tainan for relatives and friends to stay. Her sister said that she hadn't chatted with her (sister) girlfriend for a long time and wanted to stay at her home so that the two sisters could have a good chat. So I drove her sister and the child back to the suburbs. As soon as we entered the house, we chatted in the living room. Her sister's 3-4 year old child went crazy, running up and down the stairs, laughing and shouting, and wanted me to play with him. His sister saw that the situation was not right, so she said to my girlfriend: [You take a rest first, I'll coax the child to sleep, and then come to chat with you.] So we went up to the third floor, to my girlfriend's room to take a shower and watch TV.

There are two rooms on the second floor, one for her parents and the other for her grandmother. There are two rooms on the third floor, one for her girlfriend and the other for her brother. Her brother is in the army, so her sister lives in the room opposite her brother on the third floor.

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 just teased her a little. Every time I wanted... she never refused. I would gently tickle her breasts, and her nipples would become soft after a few licks. Her vagina would become moist after a few touches, not to mention that when I licked her clitoris, it would make her even more crazy... We are familiar with each other's bodies, and every time we make love, it is almost always a thorough experience. We have done it 7 times a day at most, and 3 or 4 times is common. Cumshot, titjob, anal sex (we rarely do anal sex, it's not as comfortable as described in pornographic literature), vibrator, massage stick, we have tried every possible position, except for exposure, we have no interest in almost everything else, she said we are a perfect match, to be honest, under her pretty appearance, she always wears a long skirt and has long flowing hair, speaks softly, and is a little shy, you can't imagine how lewd she is, 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 she returns to the room and has taken a shower. What are we 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, chest temperature, breast temperature, armpit temperature, rectal temperature... After saying that, she pursed her lips, wet her lips with her tongue, opened her mouth and took my penis into her mouth, and swallowed it to the bottom, then tightened her mouth, slowly pulled out the penis to the end of the glans, and 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 thought that her sister would come over to chat with my girlfriend, so I must not waste time, so I was busy taking off her pajamas. My girlfriend hesitated and said: [Don't take it all off, wait... my sister is coming over] I thought so too, anyway, she was wearing a one-piece blouse, and you couldn't tell if she was naked inside, so I helped my girlfriend to put her on the bed, picked up the hem of the blouse with my mouth, and began to move my tongue around her lower abdomen, gently biting the waistband of her small panties with my teeth, and slowly took off her panties with my mouth, licking wherever I took them off. As my girlfriend gasped softly, I knew that she was about to hold on...

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 vagina, but it was already so 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 her thighs to her belly groove, back and forth, deliberately skipping her vulva. Finally, my girlfriend couldn't bear it anymore, and held my head with her hands, guiding it to the middle area, and raised her buttocks, mumbling: [You are bad. You are bad.. You are bad... Hate... Hate...]

In order to give her immediate satisfaction, I extended my dexterous tongue, covering her entire vulva, and then used the tip of my tongue to sweep hard from bottom to top, from the anus, perineum, vaginal opening, to the clitoris. I only heard my girlfriend's satisfied sound of [Hmm, Oh~~], and her moaning began from then on.

My tongue moved back and forth inside and outside her vagina, sometimes lightly, sometimes hard, making her scream. After about ten minutes, my girlfriend's legs began to tremble, her abdomen stiffened, and her chin was lifted up. I knew she had an orgasm. After a while of shaking, she held my head and guided it upwards. Following her gestures, I stood up in front of her and hugged her body tightly. Our tongues were stirring in each other's mouths. After stopping, she moved her 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 that I liked her lewd action of holding my penis with her hand and guiding it to the vagina. It would make me very excited. Under her guidance, my glans finally touched the soft and slightly warm vaginal opening. With the expectation of each other, my glans slowly inserted into my girlfriend's vagina. The touch at the beginning was the most wonderful combination. At the same time, we heard each other's satisfied sighs. After the delicate and delicate foreplay, the second stage of lovemaking was about to begin, with fierce collisions in order to reach the peak of orgasm~~~

[Knock! Knock! Knock!]... Hmm? My girlfriend and I suddenly opened our eyes wide and looked at each other. In an instant, the earth stopped turning and all dynamic events froze... [Knock! Knock! Knock!...] The sound of the second knock on the wooden door was like an old monk's wooden fish, which made you suddenly realize something. Before I could react, my girlfriend opened her mouth and said, [Oh~ Here it comes!], then she stood up and stroked my cheeks with both hands, kissed me on the mouth and said, [Be good, don't be angry!] I had no choice but to kiss her on the forehead and said, [It's okay!!] Alas... When my girlfriend stood up, she reminded me to put on my pants and turned on the TV... I have to admire her calmness.

In a panic, I couldn't find my underwear for a moment. I only saw my girlfriend's panties and stuffed them under the pillow. She pulled the quilt to cover her lower body, put her hands on the back of her head and pretended to be concentrating on watching TV~ (You're kidding... Hehe, you know what we are doing). Her sister was already in pajamas (my eyes lit up! My dick immediately got erect). As soon as she came in, she smiled at us, revealing her beautiful white teeth. I greeted her and said, [Are you done?] Her sister said, [Yeah, the little brat was too excited! I coaxed him for a long time before he fell asleep]. My girlfriend knew that I didn't have time to put on my underwear, so she sat next to me in the middle of the bed, and then patted the other side of the bed and said, [Sister, you sit here]. Her sister sat down without hesitation, raised the pillow, and half-lying down with her upper body against the bedside table. Then my girlfriend was in the middle, and her sister and I were on both sides.

Once the two sisters started chatting, I was watching TV, sometimes chatting a few words here and there. Slowly, it was late at night, I turned off the TV and said, "I'm going to sleep first! You guys chat." Then I pulled up the quilt, put my arms around my girlfriend and closed my eyes. Her sister said, "I'm going to my room too." I quickly said politely, "It's okay! You guys chat, I can sleep well, it won't affect you." My girlfriend also said, "It's okay." (I began to regret why I was so polite. Alas~) After hearing that, she continued to lie down without hesitation and continued to chat with my girlfriend. How could I sleep? I felt so sick.

The two sisters chatted more and more, and finally the three of us were lying down, but I was in the dark (because I pretended to sleep) and they were in the light (they were still chatting). We were covered with the same big quilt. I was completely naked under the quilt, and my girlfriend was naked except for her blouse. Her sister was also only wearing pajamas. As we lay there, my hands began to get restless. I gently put my hand into my girlfriend's blouse, first touching her thighs, and then slowly moving up inch by inch. She was probably afraid that her sister would find out, so she didn't dare to resist. She turned her hand and pinched me. I ignored him and continued my groping. When I touched her butt, my girlfriend finally couldn't bear it anymore and said, "Stop it!"

I didn’t respond, so my girlfriend could only say awkwardly: [He (referring to me) would hug me when he fell asleep, and would subconsciously touch me when he was half asleep] His sister said: [Your brother-in-law is the same…] At this point, his two sisters started talking about this topic… I heard them talking about porn… some messy private sexual topics… Maybe they really thought I was asleep…

Later, her sister said: […the light…isn’t it too bright?] Then she stood up and switched the ceiling chandelier to a dim light. Suddenly, the room was plunged into dimness, which sheltered me from my rising sexual desire…and allowed me to "explore" my girlfriend's body without any scruples…her breasts, nipples, buttocks, vulva, and clitoris. With the catalysis of my dexterous fingers, my girlfriend's vagina was flooded. When I slowly pushed my fingers into my girlfriend's vagina, she couldn't help but let out a soft cry, while her sister was still chattering about her husband's family.

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

At the moment, her sister was describing in detail the trivia 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, so I didn't dare to move. I just let the swollen and hard penis stiffen straight in my girlfriend's vagina. Not long after, my girlfriend didn't care whether her sister would notice anything unusual, and began to twist her hips restlessly, hoping to get more pleasure, so I also honestly and unceremoniously began to twitch slowly, and my girlfriend also began to not respond to what her sister said, but instead moaned and panted softly...

Anyone with experience knows that the final stage of lovemaking is the arrival of intense and violent thrusting until ejaculation... the breaking point, which is the most thorough and enjoyable. How can such silent thrusting without too much movement satisfy two bodies conquered by sexual desire? I don't know how long it took, but gradually her sister didn't know if she noticed something was wrong or was she really tired... Finally, I couldn't hear her talking anymore, and instead I heard her even and regular breathing.

I peeked through my girlfriend's body to observe her sister. Even with her eyes closed, I could still see her eyeballs rolling slightly under her eyelids, and her eyelashes fluttering involuntarily... I suspected that "she was pretending to be asleep to avoid embarrassment"... I thought, since she was so considerate, I wouldn't let her down... So evil thoughts came to my mind, and I pulled my penis out of my girlfriend's body, turned her body over, let her lie flat, then spread her legs, turned over between her legs, and motioned for her to hold my penis with her hand, guide it to the entrance of her vagina (I like this action) and re-insert the glans into the girl's extremely eager vagina.

This time I had no scruples. I had been holding it back for the whole night. Now no one could stop us from having a good time. At first, I just thrusted in and out at a slightly faster frequency. After 5 or 6 minutes of wanton deep and shallow sex, 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 extend the stroke and force of thrusting. Under my all-out attack, my girlfriend forgot her shame and could not hold back her lustful voice. Her low moans turned into wild and carefree shouts. At this critical moment, we seemed to have forgotten that in the middle of the night in December, how could her sister, who shared the same quilt with us, be unconscious?

Finally, the semen that could not be held back any longer rushed out like a wild horse as I sprinted with all my strength. The sound of "pa pa..." came from the connection between my girlfriend's reproductive organs. I hugged my girlfriend's body tightly, and my lower body was still bent to push my penis deep into her vagina. My penis, which was still hard, was immersed in her vagina, enjoying the rhythm of the strong contraction of her vagina after the orgasm, and 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. I turned over and lay down in a trance, but still hugged 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, so 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 have the habit of hugging something when I sleep, if there is someone, I will hug that person, if there is no one, I will hug a pillow... I fell into a deep sleep, after tossing and turning for a few times, I hugged a soft body in a daze, and her hair felt itchy on my cheek, so I subconsciously straightened her hair, kissed her on the face, and then hugged her again and continued to sleep.

The body I was holding tightly was twisting restlessly. Between half asleep and half awake, my hands began to restlessly grope on the familiar body... In fact, there was no sexual impulse in this action, but just a subconscious intimate caress... My hands covered her breasts first, but I touched her bra?!!... I instinctively felt that it 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 also very proud of this, hehe...hehe...) The feeling of holding the plump and soft breasts in my hands always makes men intoxicated. In fact, I didn’t intend to go any further in my dream, so I fell asleep again holding the soft breasts...

I don’t know how long it took, but my hand unconsciously touched my girlfriend’s private parts. I couldn’t feel anything through her panties, so I peeled off the bottom of her panties with my fingers and probed her vagina from the side. I felt that the hairy area was already wet and slippery. At this moment, I suddenly froze and my fingers stopped moving…?!! My girlfriend was clearly naked in her bra just now, so why was she wearing a bra?! And her panties were still on?! I had kept my eyes closed before this, and I opened my eyes slightly with a guilty conscience… Suddenly, a chill quickly ran up from the soles of my feet to my head…

Oh my God! The person I was hugging... was actually "my girlfriend's sister". I suddenly became awake, but I didn't know how to end it. All my movements were frozen. The funny thing was that my finger was still inserted in her sister's vagina. In the dim light, I glanced at her sister. Her sister's beautiful face still had her eyes closed, and you could even see that she was squinting a little too hard. I suddenly realized that her sister had the mentality of an ostrich. With her eyes closed, she could be said to be asleep. She "didn't know" what was happening. If I also closed my eyes, it could be said that I had hugged the wrong person in my sleep.

So her guard was gone and her lust was aroused... In that case, I just went with the flow and resumed my finger activities, first slowly stirring in the shallow part of the vagina, then using the love fluid secreted from her sister's vagina to smear it on the clitoris and rub it gently and rhythmically. At first, because her sister's legs were not wide enough and she was still wearing panties, my fingers found it a little difficult. Without hesitation, I withdrew my hand that was caressing the clitoris and hooked my fingers around the waistband of her panties and pulled them down.

Her sister actually cooperated by slightly lifting her hips even when she was sleeping with her eyes closed?!! It was very easy for me to take off her panties... When my playful fingers returned to that private part full of love juice, I felt the "moving space" had increased a lot. It turned out that her sister automatically spread her legs a lot, making it easier for my hands to move. I also groped and played with her sister's tall, soft and full breasts... The size seemed to be slightly larger than my girlfriend's. I turned my head and looked at my girlfriend who was sleeping next to me anxiously. At this moment, she was breathing evenly and her breasts were rising and falling regularly.

After teasing the clitoris for a while, I tried to use my middle finger to slowly explore the deep part of the 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, which had made my whole hand wet. I tried to insert two fingers into the vagina to stir it, and unexpectedly found a bulge on the upper edge deep inside the 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 she had an orgasm.

I hugged her sister tightly in my arms, bent down to kiss her neck, earlobes, forehead... We stayed like this for 1 or 2 minutes, and slowly her 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 her 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 each other. 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 her hand, held my erect penis in her hand, and used the prostate secreted by my glans to rub the urethra with her thumb... I turned over and pressed her sister under me. In addition to automatically spreading her legs, what surprised me was that her hand held my glans 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 was still concerned about my girlfriend who was sleeping next to me. I didn't dare to thrust too vigorously. Besides, the object was her sister. I couldn't predict what the consequences would be if my girlfriend saw this scene?!... And at that time, I loved my girlfriend and she cared 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, I knew her sister was about to reach the critical moment again... I couldn't pretend anymore, so I whispered in her sister's ear: [...This?!!...Shall we go outside?] Her sister didn't seem to understand for a moment, and paused for a while, then nodded after a while.

What’s interesting is that her sister still had her eyes closed. I turned over and got out of bed, without even putting on my clothes, and walked out with my hard penis. After a while, I heard some rustling sounds, and her sister’s figure finally appeared in the darkness in front of me. I hugged her sister, and there was no need for adjustment in the dark. Our mouths soon entangled again, sucking each other greedily. After a passionate kiss, her sister motioned for me to sit down, so I sat down on the sofa. She squatted between my legs, first gently held my penis with her hand and stroked it for a while, then used her hand to push her long hair behind her neck (it is the most charming when a woman does this before giving a man a blowjob), then lowered her head to lick the urethra on the glans with the tip of her tongue, and then slowly put the entire glans into her mouth while her tongue kept 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.

Unable to endure such torture any longer, I stood up and lifted her sister's body and let her lie on the sofa. I lifted her pajamas. The body inside the pajamas had been stripped naked by me. Now her sister was completely naked. I spread her legs wide apart and eagerly inserted my hard and unstoppable penis into her vagina. As I inserted it, her sister let out a satisfied cry. Here we had no scruples and fucked her fiercely without any cover. In the ups and downs of the slapping, I wantonly ravaged and played with her trembling and plump pair of beautiful breasts. The sound of the penis colliding in the vagina filled with obscene fluid, as well as the moans from her sister and my panting, echoed in the dark space...

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: [Um... Oh... Ah... No more, No more, I can’t take it anymore... I’m so numb... Um... Oh... Ah...] Finally, I couldn’t hold back 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 anymore, and the swelling of my glans made her sister feel that I was about to ejaculate. Her sister hugged my waist and almost shouted: [Um... Oh... Ah... It feels so good... Fuck me to death... Cum inside! Cum inside!... Um... Oh... Ah...] ]

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

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

We didn't say anything after that, just hugged each other until the sky outside the window gradually turned white, then she said: [Go to the room and go to sleep...] I kissed her forehead, got up and went back to the room, turned around to look at her sister, she was still sitting alone on the sofa, when our eyes met, she waved at me and told me to go in quickly.

I returned to the room and saw my girlfriend still sleeping soundly. I crawled naked into the quilt and hugged my girlfriend in my arms. She hummed, opened her sleepy eyes and looked at me, then kissed me on the lips and closed her eyes and fell asleep again...

This evening, I accidentally fucked my girlfriend's beautiful, flirtatious and slutty sister... I... It was so great!
