Me and My Sister-in-Law (Family Incest Adult Fiction)

My wife Xiaowei and I have been married for two years. My wife has an older sister who is five years older than me. Although she is not particularly beautiful, compared with my wife, she has more charm of a mature woman.

From the first time I saw her, I thought it would be great if I had the chance to fuck her once in the future. When I usually have sex with my wife, I sometimes imagine my wife as my sister-in-law, which makes it more enjoyable when fucking her.

We have been living in peace for two years since we got married, and I have never found an opportunity to contact her, until this summer my wife went to study in another place and was not at home for several months. For a normal young person like me, who is already married and has a normal and regular sex life, suddenly sleeping alone for several months is of course unbearable. So when I can't stand it, I will lie on the bed and masturbate alone, and when I masturbate, sometimes I think of my wife, and sometimes I just masturbate thinking about her. One Sunday, I was bored at home and went to an adult website for a while. Looking at those adult pictures, my dick became hard involuntarily, so I lay on the bed, took off my clothes, and started touching myself. After touching it for a while, I heard the sound of a key opening the door. (Because my house and my sister-in-law's house are very close, we have each other's keys. When my wife is away, my sister-in-law often comes to help me with odd jobs and clean the house).

Before I could even put on my clothes, my sister-in-law came into the room. When she saw me naked on the bed, her face suddenly turned red. She felt it was not right to come in, nor to leave, so I quickly put on my clothes and said hello to her. She came into the house and lowered her head to clean up the house. I was thinking, how embarrassing it would be if she saw me like this! I tried to talk to her to ease the atmosphere, but she just kept replying and never dared to look up at me, as if she was very afraid of me. Because I had just started masturbating and hadn't even ejaculated when she came in, so my dick was still feeling uncomfortable.

I looked up at her. It was summer and everyone was wearing less. When she lowered her head to work, her breasts were visible from her collar. Although her breasts are not very big, they are very firm, which makes me feel itchy. I thought, how nice it would be if I could have sex with her right now, which would just solve my urgent problem. I said to her, "Xiaowei has not been at home these days, and I really couldn't stand it, so I behaved like this just now." She lowered her head and said, "Oh, it's nothing." Then she added, "These are normal human physiological needs. Don't worry, I won't tell anyone." Then she looked up and smiled at me.

When I saw her eyes, I felt that there was a kind of understanding and care in them, and she didn't mean to laugh at me at all. I suddenly thought to myself, maybe something could happen between us today. But I never dared to do anything rash, for fear of angering her. After a while, the house was cleaned up and she told me that she was leaving. I thought that if I didn't take action now, I might never have another chance in the future. I walked behind her, hugged her and held her breasts with both hands. She seemed startled and asked me, "What are you doing?" I put my mouth close to hers, kissed her ear and said, "Sister, you've seen it just now. I've been unable to hold it back for the past few months. If I go on like this, I'll get sick. Please help me!" She twisted her body and said, "How can I do that? What if Xiaowei finds out?" I was already feeling uncomfortable with the desire, so I didn't care about anything else. I said, "No, she won't know." At the same time, I reached my hands into her clothes and touched her body all over. Things had come to this point, how could I let her go? After a while, I felt that she was no longer struggling, and her body seemed to react. She seemed unable to stand and gradually leaned towards me. I held her in my arms, slowly walked to the bed, and laid her down on it.

Because it was summer, we were both wearing less. I quickly took off my clothes and then stripped hers. She no longer tried to stop me, but just closed her eyes and stopped looking at me. I began to slowly appreciate the naked body of this woman. My sister-in-law is 35 years old this year. She is no longer young and her figure can no longer be compared with that of young girls, but it is already good enough that she can maintain her current figure. The most important thing is that I haven’t touched a woman for several months. Now my whole body is engorged with blood, and my dick is swollen. I really want to thrust my penis into her pussy and fuck her hard right now, but then I think it's better to go slower and take care of her emotions instead of just thinking about myself. I lowered my head and pulled open her lower body, looking at her pussy. Her pussy lips were already black, probably caused by having sex with her brother-in-law many times.

Her lower body was still dry, so I lay down and slowly kissed her pussy. In the past, when I had sex with my wife, I also liked to kiss her little pussy first. Today, I also wanted to do the same to my sister-in-law. At first, she just closed her eyes and didn't move or say anything. I used all the tricks I used on my wife, playing with her clitoris with my tongue while touching her perineum and anus with my hands. Slowly, she began to moan slightly and enjoy it, slowly twisting her ass to cooperate with me, and the pussy juice flowed all over her ass. I thought I couldn't just lick her like this, I had to let her lick me too, so I lay down and said to her, "Sister, you should lick me too." She hesitated for a moment, then knelt in front of me, holding my cock in her hand. Now my cock was swollen and black and red, more than ten centimeters long and thick. She played with it with her hand for a while, then lowered her head and put the cock in her mouth and started sucking. Suddenly a feeling of electric shock spread throughout my body. My wife has sucked cocks before, but her technique was not very proficient. Today I realized that my sister-in-law is much better than my wife. My brother-in-law is so lucky.

I saw my sister-in-law sometimes swallowing the entire cock and sometimes spitting it out. Her tongue tip kept drawing circles on the head of my cock and she kept rubbing my cock with her lips. That was not all. She also held my testicles from time to time and even lifted my butt and licked my anus. ah! It was so comfortable that I said while enjoying it, "Sister, you are so good. I am about to ejaculate while you lick me!" After a while, I felt that I was really about to ejaculate, so I quickly asked her to stop. I didn't want to ejaculate so quickly. I asked her to lie on the bed and I turned around to find a condom. My wife and I had always used condoms. My sister-in-law probably understood what I meant and said to me, "You don't need to wear a condom, you can cum inside."

I was ecstatic when I heard this. I had always complained to my wife that wearing condoms was uncomfortable, but I never thought that today I could wear a condom and ejaculate inside my sister-in-law's pussy. I lay on top of her, caressing her breasts with my hands, and leaned close to her face and said to her, "Sister, I've wanted to fuck you for a long time. Now I'm going to fuck you. Will you let me fuck you?" My sister-in-law nodded. I wanted her to say it herself that she wanted me to fuck her, but she refused to say anything. I think, even though you don’t say anything now, just wait and see how I’m going to deal with you later. I spread her legs apart and lifted them up, then aimed my dick at her pussy. Her pussy was already very wet and slippery, so I pushed my dick all the way in with a "swish" sound, making her scream "ah". After all, my sister-in-law is 35 years old. She has been fucked so many times and has given birth to a child. Naturally, her pussy is not as tight as my wife's. But when my dick is inside, it feels slippery and hot, which is a different feeling. I said to her, "Sister, there's quite a lot of water coming out of your pussy!" My sister-in-law said shyly, "It's all because of you!" I smiled and slowly started to fuck her pussy. At first, my sister-in-law just gritted her teeth and refused to make any sound. I asked her, "Are you comfortable?" My sister-in-law just nodded.

I said, "If you feel comfortable, just scream out. It will make you feel better!" "No... I'm afraid you'll laugh at me if I scream out." "Don't worry, I won't laugh at you. Besides, you should scream when you feel comfortable. It's so uncomfortable to hold it in." "You really... won't... laugh at me?" "Don't worry, sister. I will never laugh at you." The sister-in-law then began to moan slowly. I listened to her moans and fucked her pussy even harder. "Ah...comfortable...you make me so comfortable!" Big sister, your pussy is so wet, your pussy is so slippery, and my cock feels so good.

"After fucking like this for a while, my sister-in-law was no longer reserved. She hugged me with both hands, raised her ass high, clamped her legs around my waist, and moved with all her strength in coordination with me. While I was fucking her, I said, "Sister, it's so great to be with you. You make my cock feel so comfortable!" Are you happy? "My sister-in-law also nodded and moaned, "Ah, it feels so good, my dear brother-in-law, you are going to fuck me to death!" "At this moment, I suddenly pulled out my cock, and my sister-in-law's pussy felt empty and uncomfortable. She was so anxious that she kept shouting, "Hurry... fuck me... why did you stop?" "I will only fuck you if you beg me to fuck you." "I know that at this time, no matter what you ask her to say, she will agree. Sure enough, she shouted: "Good brother-in-law... come... come and fuck big sister... big sister's pussy... is swollen and uncomfortable... ah... come... "," What can I use to fuck you? "Use your...big cock...to fuck my...cunt...hurry up...stop torturing me...big sister...I really can't stand it..." I used all my strength to shove my big cock in all at once. I looked down at her. Her hair was now disheveled, her eyes were half open, and her ass was twisting. How could she be the familiar, dignified and quiet sister-in-law I knew every day? She had turned into a slut under me. I couldn't even recognize her. She was a hundred times more slutty than my wife. It seems that women's dignity is just an act. Women are naturally slutty. As long as you make her feel comfortable, she will submit to you. I continued to fuck for a while. Her breathing became faster and faster, her face flushed, and she kept shouting, "Oh...it feels so good, fuck me hard...fuck me...oh...oh...fuck my cunt...oh...I can't take it anymore...ah...fuck me to death."

"Your cock... is so big... and so hard... my pussy... is all filled up by you." "Harder...harder...oh...oh...it feels so good...my dear brother-in-law...I feel so good when you fuck me...fuck my...pussy...fuck it to pieces..." I knew she was about to reach orgasm, so I increased the speed of fucking her. She hugged my back tightly, screaming "ah ah" and calling my name. Suddenly she screamed, closed her eyes, and twisted her body wildly, reaching orgasm. I felt her pussy tighten, squeezing my cock so tightly, and I almost came again.

I lowered my head and kissed her face. After a while, I asked her, "Did you feel comfortable just now?" "She opened her eyes and looked at me, smiled embarrassedly and said: "You've almost fucked my pussy to pieces, I'm almost dying of pleasure, you're so great!" I heard from Xiaowei that you are very capable and often fuck her to the point of almost reaching heaven. After all, you are a young man, so you are really capable. "I said: "You have gone to heaven, but I haven't yet. What do you think I should do?" "She said to me: "You must be tired, come down and rest for a while, let me be on top of you." "This is exactly my favorite position. I quickly lay down, and she rode on me, held my cock with her hand, and slowly sat down. She said: "Xiaowei has not been at home for these few months. It has really been hard for you." I see you're really holding it in, so today I'll take Xiaowei's place and let you have enough fun!

"She began to move her body up and down, left and right. The feeling of being below and being on top is completely different. Fucking a woman and being fucked by a woman are different. I reached out and touched my sister-in-law's breasts, enjoying this happy time. My sister-in-law asked me softly: "Is it fun?" "My sister-in-law's skills are indeed better than my wife's. I praised her: "Sister, your skills are really good. I have never felt so good before." "She smiled and said," As long as you feel comfortable, it's fine. I'm not afraid that you will think I'm old!" "I quickly said: "No, no, in fact, the older the pussy, the more pleasurable it is to fuck. It's more pleasurable when I fuck you than when I fuck Xiaowei!"

Besides, a dick like mine that has been pent up for so long really needs a pussy like yours to relieve it! "My sister-in-law smiled and worked harder. She bent down and put her breasts in my mouth. I held her ass with both hands, sucking her breasts while enjoying her pussy. My sister-in-law had so much pussy juice that it made my cock hair all wet and cool. I didn't care about that at all. I raised my ass and thrust hard into the depths of her pussy." Sister, you make me feel so comfortable when you fuck me. You're so slutty. "I kept moaning, and slowly, a feeling of pleasure came from my cock," I'm going to cum, I'm going to cum," I shouted loudly, and she also cooperated with me to moan, and I shouted and shot a stream of hot semen into her pussy.
