My Girlfriend's Sister Is Having a Crazy Spin (Martial Arts Science Fiction Adult Novel)

One of my college girlfriends was Xiaozhi, a nurse. I was just a sophomore at the time, but she had already graduated from nursing school and was working in a hospital in Taipei. Once, I happened to have no classes, so I excitedly ran from Taichung to Taipei to find her. I originally just wanted to play for a while and then go back, but she was so excited that I couldn't resist her request, so I had to skip the next day's class and wait until she finished her late night class to accompany her.

She rents a house with her sister Xiaoyun in Taipei City, which has two bedrooms, a living room, a bathroom and a basement. After sending her to work that night, I went back to her place and waited for her to get off work in boredom.

That night, Xiaoyun didn't know that I came to see her sister. Because I had just played and was a little tired, I lay down on my girlfriend's bed in a daze. Xiaoyun had just broken up, and when she came back, I heard her sobbing in the room. I thought it was not convenient to disturb her, so I didn't go over to say hello to her and continued to lie down. After a while, bursts of moaning sounds came from her room, along with one or two screams.

I walked to the outside of her sister's room out of curiosity. The moaning sound became more and more obvious, which made me curious so I opened the locked door of her sister's room (luckily she was so engrossed in her play that she forgot about the sounds from the outside world). I saw that she was only wearing a pair of sexy panties with holes on her body. She closed her eyes and thrust the vibrator into her vagina.

I took a look and couldn't help but go over and snatch the vibrator from her sister's hand and help Sister Xiaoyun fuck her pussy hard. Her sister was suddenly startled, opened her eyes and looked at me, exclaiming, "Why is it me?" But because I was pressing tightly against her sister, Xiaoyun couldn't escape and could only let me play with her pussy as I pleased. I simply asked Xiaoyun, "Sister, were you masturbating just now? Is your vagina itchy?" Poor Xiaoyun could only say to me in an almost pleading tone, "Stop playing, you're so lewd! It's so itchy, please, Xiaoan, stop now!"

I half-tricked and half-coaxed Xiaoyun and said, "I'm sorry, sister. I can't stand hearing your voice. Can you let me play for a while?" Her sister just nodded shyly and told me that it was only for a while.

I saw the opportunity and continued to thrust the vibrator. I saw her sister covering her eyes with both hands and kept asking me if I was ready. I had already talked to her sister, but my mouth was not idle. I suddenly went down and put her legs on my shoulders, and gently licked her tender pussy with the tip of my tongue. I saw Xiaoyun's legs shaking involuntarily, and she wailed nervously. I deliberately told Xiaoyun that it was so wet. While I was licking her sister's pussy hard, I saw Xiaoyun began to shake her hips and clamped my head tightly with her legs, and kept saying, "Xiao An is itchy, I'm almost itchy to death!" While her sister was twisting her waist and hips in ecstasy, I suddenly stopped licking the pussy, stood up, spread her legs to my waist, and inserted my cock into her pussy hard. Her sister was startled and pushed back nervously, trying to escape. Her sister begged me not to insert it again and asked me to let her go.

I had no choice but to coax Xiaoyun: "Sister, I will just insert it a little longer, just let me feel comfortable and then I will pull it out."

Because I hugged her tightly, her sister had no choice but to promise me, "Don't lie to me!" Suddenly the bedside phone rang - Xiaoyun said to me nervously, "Wait a minute, I'll take a call first!" I heard a boy's voice from the other end of the phone - Xiaoyun? What are you doing? (Because the microphone is very loud)

Xiaoyun said fearfully: No!

Boy (in a very lewd voice) - Open your thighs and touch your pussy quickly. Xiaoyun (looking at me helplessly) - No, that's very lewd. As soon as I heard Xiaoyun's obscene conversation with a strange man, I immediately pumped my dick in her pussy. Xiaoyun moaned helplessly. I didn't know if she was talking to me or begging the boy on the other end of the phone - Stop quickly, I can't stand it anymore, it's so itchy. Boy - Please put the vibrator I gave you in there quickly, I want to hear the sound of the vibrator. Xiaoyun - No, I'll want to be fucked like this!

As soon as I heard Xiaoyun's blurt out, I immediately pulled out my cock and pushed the vibrator back into her wet pussy, letting it ruthlessly destroy her tender pussy!

Xiaoyun - You men are so bad, you only know how to bully me!

Boy - Didn’t you have a lot of fun at the party last time?

Xiaoyun found that I seemed to have discovered her secret, so she turned her head away and remained silent. The boy said to her in a bad way - I'm going to take a shower later, I'll call you again. After Xiaoyun hung up the phone, I just sucked Xiaoyun's tender breasts with a lustful look and touched her wet pussy.

I was speechless, but Xiaoyun told me nervously: "I was tricked by my friend to go there, don't listen to what that pervert said."

But I was busy spreading Xiaoyun's labia, didn't want to listen to her explanation, and held the dick in one hand. Sizzle! A sound. The penis was inserted into Xiaoyun's soft and moist vagina. A warm and slippery feeling followed by Xiaoyun's unconscious moan: Oh, it's so itchy, my sister is so itchy, please let me go!

I lifted Xiaoyun's legs high and put them on my shoulders, thrusting in and out at a moderate pace. Each time you thrust, make sure you push all the way in.

I looked at Xiaoyun, her lustful expression and eyes looking up at me from time to time, and I heard Xiaoyun's moans getting louder and louder. There was really no feeling more comfortable and happy than at this moment.

My cock kept fucking her pussy, and I saw Xiaoyun's juice kept flowing out. Her body catered to me, and she kept twisting her waist. With one hand, she kept rubbing her breasts. Xiaoyun kept shouting that she couldn't stand it anymore. I couldn't stand it anymore, can you fuck me harder?

I pretended to be stupid and asked her, Xiaoyun, can you explain it more clearly? Xiaoyun rolled her eyes and said: You are so bad, my pussy is so itchy, I want your big cock to be harder to help me relieve the itch.

When she wasn't paying attention, I put Xiaoyun's legs on my shoulders and inserted my hard big glans into her vagina that was constantly oozing love juice. I watched my cock come out and be swallowed up by Xiaoyun's vagina. I could only hear Xiaoyun wailing: "Ah-ah-don't do this...ah-ah-so-good...quick...quick..." Xiaoyun screamed unconsciously. I quickened my sprint.

Xiaoyun's pussy seemed to have suction, sucking my cock. Her labia tightened and loosened, sucking my cock into her vagina. Her pussy juice constantly stimulated my cock, and waves of pleasure spread throughout my body. I straightened my waist and pushed my cock hard to the bottom, deep into Xiaoyun's uterus.

I found that I only penetrated halfway into my sister's pussy before I reached the bottom. Her labia was stretched wide open by me, and her pussy juice was flowing out. I started to thrust hard, and Xiaoyun couldn't help but scream, "Oh... so beautiful... your big cock makes my pussy so full and full... oh... my pussy is itchy and numb. It feels so good..."

Her moans aroused my sexual desire, which made me fuck her harder. Every time I penetrated her, her sexual fluids would gush out, making the bed sheets wet. Every time I moved, her labia would turn outward. I used my skills, grabbing her breasts with both hands and rubbing them hard. She cooperated by twisting her waist and hips, and snap! Bang! Bang! The sound of the collision between the buttocks made Xiaoyun reach orgasm involuntarily! She couldn't help but wail: Stop playing, my pussy is almost broken!

Suddenly, Xiaoyun's body twitched involuntarily, and a lot of vaginal fluid flowed out. She kept gasping for breath, her eyes rolled up, and her thighs were still shaking unconsciously!

I knew she had an orgasm, and I was actually almost at the end of my climax, but I half-lied and half-coaxed Xiaoyun by saying, "Tell me the story of how you were deceived, and I will stop fucking you." Xiaoyun nodded slightly and took out a book from the bedside table.

The first one is "Sister's Private Diary". I can't wait to open it and I'm surprised to find that it is Xiaoyun's own diary. I quickly read it and saw more and more private stories. I roughly summarized it as follows:

A certain day of a certain month-1 It has been a year since I started to be with my brother, but the feeling between me and him is getting weaker and weaker. It is so strange! Is it true that love fades when it is deep?

On a certain day of a certain month-2 My brother's friend Xiaowei is really bad. He flirts with girls everywhere. I heard from my brother that he is very fickle and even abandons girls. Such a person will definitely get his comeuppance.

Xiaowei has been acting strange lately, calling me all the time. Ever since he used the excuse of helping his sister transfer to another department, he has been asking me all kinds of questions. I have a bad feeling.

Month and day - 4 Today I couldn't help but give Xiaowei some moral advice, telling him that he shouldn't be unfaithful anymore. I didn't expect him to confess out of nowhere, saying that he had been abandoned by the girl he loved the most before, and that he envied his brother for having a girlfriend as good as me. I didn't know how to proceed -

On a certain day of a certain month - 5 Today I couldn't resist my curiosity and asked Xiaowei why so many stupid girls were willing to be with him. He actually answered me that it was because of sex. I comforted him and said that it was actually just a momentary pleasure and girls still needed a stable relationship. I didn't expect him to ask me if I had ever worn a thong. I didn't know how to answer him and quickly said no. However, he actually started discussing the issue of girls' sexual desire with me and asked me if there were any changes in the sensitive areas between my brother and me. It's strange, why didn't I refuse him from talking about this topic?

A certain day of a certain month-6 Today my brother took me to dance. I was so happy, but I unexpectedly saw Xiaowei's evil side. In a dimly lit place, I saw Xiaowei hugging a hot girl. The sister's T-shirt and bra were pulled up, revealing her breasts for Xiaowei to lick, and he also kept stroking the hot girl's buttocks. It seemed that Xiaowei had raped her, and from the lustful expression on the hot girl's face, it could be seen that she was enjoying it very much.

I saw the sister sitting on Xiaowei's legs and shaking her head as she was being fucked, letting Xiaowei lick her two erect nipples.

As I watched, I noticed a few drops of sticky liquid flowing between my legs, and my breathing and heartbeat gradually became rapid. My brother suddenly appeared in front of me and asked me what happened and why my face was red. I didn’t know how to answer him. I had to tell him casually that the air might be bad, and then told my brother that I was going to the bathroom to touch up my makeup and asked him to wait for me.

When I was walking through the corridor to the bathroom, I was stopped by a strange man who asked me if I could dance a slow dance with him.

I actually said boldly: Whatever! On the dance floor, he blew into my ears and his hands wandered restlessly on my body. Suddenly he leaned over to my lips and gave me a deep kiss. I didn't have time to react, and plus I was so excited by what I was watching that I couldn't resist at all. Soon, I was completely powerless and let him do whatever he wanted.

He turned my body around and hugged me tightly from behind. He further moved his hands to my chest, kneaded my breasts through my clothes, and gently teased my nipples that had already become erect and hard with his thumb and index finger. "No... No... Ah..." He unknowingly inserted his rough fingers into my dress and continued to play with my breasts.

I didn't expect that my breasts would be played with so easily in a pub, and it was a stranger I didn't know. Even I couldn't believe it! Did Xiaowei stimulate me? ...As I panted, he seemed to be encouraged and boldly moved his hand down to explore, pulling up my babydoll evening dress, touching my thin thong and the sparse pubic hair that was exposed.

He began to use his right hand to turn over my two wet lips and clamp the thin strap of my thong, and touched my little bean with his fingertips, and tightened my thong, causing me to start moaning.

He tempted me in a low voice: "It's so wet, it will be more itchy if I slide my dick on it." When he slid his dick on my sister, I couldn't help but moan: "Ah...ah...don't...don't do this...ah...well...gently...

Oh...ah...don't put it in...ah..."

He started to use his cock to fuck my pussy, making me feel itchy and pleasurable, and my pussy juice kept flowing out with his fucking.

"Ah...ah...come on...I...can't...bear it...ah...I'm...going to...lose it...ah...ah!" Before long, I was being fucked so hard that a large amount of vaginal fluid was gushing out between my legs, soaking my white, round little butt and thighs.

At this time I still had my back to him "Ah...ah...ah...ah...ah..." I was standing with my upper body slightly leaning forward. He was thrusting in and out very vigorously. I was bending forward, holding onto the wall with my hands straight, and my legs were slightly open so that he could easily hit me from behind my ass. I was moaning in his fucking, and soon I couldn't control myself and was about to orgasm. My whole body suddenly spasmed, my vagina kept contracting, and liquid like a spring came out. His penis was tightened by my contracting vagina, and suddenly my vagina was pushed hard, and hot liquid shot into my vagina, causing me to contract continuously. After the man ejaculated, he took my penis away, leaving me in a dark corner, leaning weakly against the wall, slowly walking towards the bathroom.

After cleaning myself and just walking out of the bathroom, I saw Xiaowei greeting me nonchalantly, and the man who had just had sex with me was standing next to him, grinning at me with ill intentions. I was stunned on the spot, not knowing what to do. Suddenly my brother appeared and said to me, "Xiaoyun, are you feeling unwell? I'll take you home first." I nodded slightly. When I passed by Xiaowei, he actually walked out of the dance hall with me and my brother. However, he took advantage of my brother to get something from the locker to secretly touch my lower body without underwear and inserted his fingers into it. I could only turn my head away and let him play with me until my brother appeared.

The hateful thing is that my pussy was so disappointing and kept leaking out sexual fluids. Only then did I realize Xiaowei’s terrifying side, but it was too late! The consequences of being discovered were really terrible. He pulled me into the VIP room, pressed me on the sofa, and kissed me while one hand was already rubbing my clitoris fiercely and one finger was inserted into my vagina... I was inexplicably excited by his touch, and I was so wet down there. I couldn't understand why I was about to collapse?

"Oh! Please let me go! I can't stand it anymore! My brother will find out." I felt an inexplicable fear and couldn't help moaning. Xiao Wei mercilessly put his fingers in my vagina and thrust them in and out quickly, grinning obscenely: "It's too late! Xiao Yun, I caught you cheating. I saw your lewd look just now!"

Hearing his verbal threats towards me, I could only close my eyes, cover my face with my hands and dare not say anything else!

All I knew was that my legs were spread wide open and he took off my evening gown, leaving me with only my bra!

Xiaowei suddenly lifted my butt and thrust in hard all at once, "Ah...ah! Too hard!...So sensitive! Oh my God...You're killing me!..." My petite body was held tightly by him and thrust in hard. I had no strength to respond. I just knew that my vagina was contracting disobediently. He pushed his abdomen forward again, and his entire penis entered my vagina. When it reached the opening of my uterus, he rubbed it three or four times, then pulled it out halfway and thrust in again.

"Oh...Oh!...Ah...Ah!..." I could only scream in agony, my whole body shaking constantly!

"Xiao Yun's pussy feels so good when I fuck it! It feels so good!...Haha...haha..." Xiao Wei shouted wantonly.

Suddenly my brother called me. I looked at Xiaowei nervously, but I didn’t expect him to pick up the phone and tell my brother that Xiaoyun wanted to vomit. He took me to the bathroom in the VIP room and would send me to the door later. While he was talking to his brother, his cock did not let go of me and continued his lewd behavior.

I just felt extremely excited and had forgotten that I was being raped. I was still enjoying the waves of pleasure coming from my lower body. I knew the climax was coming, and finally he ejaculated a stream of semen into me... "Ah!!!..." My vagina spasmed involuntarily, and I greedily sucked his cock. I was still disobedient and leaked a lot of vaginal fluid. After Xiaowei smeared the remaining semen on my body, he helped me put on my clothes and told me to get up. However, I was completely exhausted and could only ask him to help me out. The door to the dance hall was quite far away, and I collapsed on Xiaowei helplessly, letting him support me towards the exit. However, the strange man appeared again and helped me out with him. The sexual misconduct did not stop, and they continued to caress my clitoris until I walked out of the door and saw my brother. The second article, "Things not mentioned in the diary",

After I finished reading this story, I looked at my elder sister with lust and suddenly asked her, "There were other people in the box that day, right?" Xiaoyun suddenly looked at me in surprise and asked me in surprise, "How did you know?"

I smiled and said to her, "Otherwise you wouldn't have been played to the point of being unable to walk!" She could only nod helplessly, and slowly started to talk about it - in fact, there was not only Xiaowei in the box that day, there was also the boy who had sex with me, and my brother's classmate Xiaohu. After Xiaowei helped me put on my clothes, the two of them suddenly came in. What's worse, my brother called again and told me that he had something urgent to do and asked Xiaowei to take me there. I could only perfunctorily agree.

As a result, Xiaohu immediately grabbed my breasts, and my baby doll skirt was pulled up and taken off by Xiaowei, and my two cute balls of flesh were completely exposed to the three wolves. I kept struggling, but it only aroused their desire. The stranger forcefully spread my legs apart, opened my wet labia with his hands, and aimed his glans at my pink vagina, which he slid in and inserted completely. I knew that I was being raped and that I shouldn't have any pleasure, but I really couldn't control my body's reaction. The love juices of my pussy gushed out like a flood, and the fire of desire melted my reason. I began to release my long-suppressed sexual desire, and my moans became louder and louder. My body also began to cooperate with the stranger's thrusting, and from time to time I tightened my pussy muscles to clamp the stranger's giant rod. When he found that my pussy would contract, he began to thrust into my pussy roughly without mercy, squeezing the entire giant rod in every thrust. I knew my labia had been turned over!

At the same time, Xiaohu grabbed my breasts and kept rubbing them, and kept licking my ears. My breasts were quite soft, and his fingers played with my nipples, rubbing them between his fingers. His mouth also left my ears and licked my nipples. I knew that my nipples were hard due to excitement, and their saliva made them wet and slippery. I could only beg them, "Please... please, don't... don't do it anymore..." But the stranger's penis was still going in and out of my vagina. I was already extremely excited, with my eyes closed, until the semen sprayed on my clitoris, and the love fluid from my lower body slowly flowed down along the groove of my buttocks.

But the lewd act was not over yet. Xiaohu then grabbed my legs from behind, lifted up his hard cock, and inserted it between my open labia. I could only watch helplessly from a close distance as I was raped by my brother's bad classmate Xiaohu. He fucked me from the front for a long time, then bent down to lick my nipples with his tongue and bit them making a "pop" sound. I could only moan and close my eyes, letting him play with my body. I was trembling all over as he fucked me, his cock pumping and stirring in my pussy, bringing me to another orgasm - I forgot how I got home, I only know that night was a very lustful and lascivious one
