【Me and My Sister-in-Law】 (Family Incest Adult Novel)

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, lowered her head and started to clean up the house. I was thinking, what? If the goddess saw me like this, it would be so embarrassing! I tried to talk to her to ease the atmosphere, but she just kept replying and didn't dare to look 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 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 acted like this just now." She lowered her head and said, "Oh, it's nothing actually." Then she added, "These are all normal human physiological needs. Don't worry, I won't tell anyone." Then she smiled at me. When I saw her eyes, I felt that they were full of understanding and care, and there was no intention of making fun of me at all. I suddenly thought, 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? I'll be so scared if Xiaowei finds out." I was already feeling uncomfortable with the desire, so I didn't care about that. 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, 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 it 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 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 her 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 and held my cock in her hand. Now my cock had become 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 began to suck. 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 may have understood what I meant, and said to me: "You don't have to wear a condom, you can cum inside my sister-in-law's pussy." I was ecstatic when I heard that. I had always complained to my wife that wearing condoms was uncomfortable, but I didn't expect that today I could wear a condom and cum 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, and now I'm going to fuck you, will you let me fuck you?" My sister-in-law nodded. I wanted her to say with her own mouth that she wanted me to fuck her, but she never said 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 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 cock is fucked in it, it feels slippery and hot, which is a different feeling. I said to her, "Sister, there's quite a lot of juice 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 feel better that way!" "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 smooth, 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 to cooperate 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, "Oh, 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 push 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? 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 all pretended. Women are naturally slutty. As long as you make her feel comfortable, she will surrender 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...it...rots..." I knew she was about to reach orgasm, so I increased the speed of fucking her. She hugged my back tightly and screamed "ah ah" and called my name. Suddenly she screamed, closed her eyes, and twisted her body wildly, reaching orgasm. I felt her pussy tighten and clamped my cock so tightly. I almost came again.
