This is the first part to my story about my mother in law and me. When they say you marry your wife, you actually marry your wife’s mother, I know now that is a true statement. It wasn’t until my wedding day that I started imagining myself with my mom to be. Her name is Jen, she is 53, 5’9 and 140 pounds. She has long light brown hair and has medium sized breast, with big nipples, can see them through her shirts. She is in average shape but looks great for 53 and for raising a family of 4. During the reception she looked ravaging in her slim strapless blue dress. I tried hard to keep looking at her but it was too hard to resist. As I was dancing with Jen, I felt my pants begin to bulge, I tried to keep it in check but it was no use. Then she came closer to me, held on tighter and I know she felt my growing cock up against her. I can feel your heart racing and her breathing increase. It was then I knew I had to have her no matter what happens.
As time passed, I tried to keep her out of my mind but we lived close to my wife’s family and would see them often. Things started very small, I would notice little things Jen would do. When I would come over she always made a point to wear something as to when she would bend over I could see her beautiful breast trying to escape the bra she would be wearing. When she would bend over to pull something out of the oven, the back of her shirt would rise up, exposing her lower back and I would just picture myself cumming all over her back. The bed was during the summer, they had a pool so we would all go swimming. I would wear sunglasses so I could look at her in her bathing suit without being noticed. Jen was a very conservative person, married 30 years but still knew deep down she was unhappy. I would fantasize about meeting her in the little pool room, grabbing her and holding her up against me. The same time I would move her bottom swim suit out of the way, exposing her wonder bush of hair and feeling her wet pussy on my fingers. Then undoing my swim trunks, letting my thick seven inch cock flop out, semi hard waiting for her to grab hold and starting stroking back and fourth. I then stuck my tounge in her mouth and kissed her deeply as I continued to shove my fingers deeper inside of her. My hand was soaked and I began to feel her start to shake and I knew she was having her first orgasm in probably several years. She looked at me and said we should not be doing this, this is wrong, you married my daughter! I told her how I felt about her and said this will be our secret. No one will ever know otherwise both of our family’s will be torn apart. Jen was still hesitant but when I looked in her eyes, saw the confidence and knew the secret would be safe.
When my wife and I would have sex, I would always imagine it was Jen whom I was with. The thought of me being able to have my wife’s mother just made me cum quicker. My wife would often ask me “what has gotten in with you” I would simply just say “nothing really, just being me”. Every time my wife and I would have sex, I always picture Jen. It was Jen’s pussy I was licking or it was Jen’s mouth over my cock and taking my load. The fantasy was becoming almost unbearable and I knew I had to make this a reality.
A year later I finally got brave enough to make my move. Each year we all take a family vacation, my family, Jen and her husband as well as my wife’s brothers and sister. We would rent a big house near a lake or ocean and spend the week there. I knew it was going to be crowded but the house was huge and I knew I would have my chance. While on vacation I would always make a point to ask Jen if she needed any help with dinner or laundry. She would always be working, helping out others but no one really cared about her or her needs. She would always thank me for helping out while everyone else would be out at the pool or went for a walk. While we were both on the laundry room I made a point to run my hand across her back as I was trying to move around her to leave the room. Jen just looked at me and smiled. I smiled back, she thanked me for helping her and I told her, I am always happy to help out. Since she did not say anything about my hand on her back I decided to go little further, I went upstairs to my room, my wife is taking the kids for a walk with my father in law. I made sure to leave the door unlocked and began to undress to take a shower. I knew Jen would be checking the rooms for laundry, just has I saw her start to open the door, I made sure my pants were down and my semi hard cock flopped out of my boxers. Jen just stopped, did not say a word, just looking at me. Of course I tried to pretend to apologize but she knew I had set her up. Jen finally cracked a smile and said “well, my daughter is very lucky!” Jen could not staring at my now rock hard member, I said “I am going to take a shower, would you like to join?” Jen’s face turned red and she started to make excuses why she shouldn’t be in the room with her son in law. I smiled and simply said “Jen , I have always found you attractive, I know where my wife gets her good looks.” I told her how when I married your daughter I was actually marrying you, so why not enjoy ourselves. I explained that this would be our sacred secret and she would never have to worry. After a few moments I went ahead and got in the shower, hoping she would join me. As I began to soap up, I heard the glass shower door open and there she was! I couldn’t believe that she was in the shower with me! My fantasy has finally come true. I had never seen her completely naked before but it was far better than I had imagined. Her breast were larger than I had thought, her nipples were already hard. Jen had a nice full Bush of hair but could tell she did manage it. As the water came running down her chest and her pubic hair was beginning to get wet. I put my arm around her lower back , guiding her closer to me. My hard cock was up against her stomach and I started to put my hand down on her butt. I told her to relax and that I would take good care of her from now on. She smiled and started to put her hand on my throbbing cock. I began to kiss her neck and folding her breast. She was so warm and I could feel her heart beating faster. Then I moved my hand down below her stomach, running my fingers through her beautiful bush. Finally touching her lips, she was already soaked and it wasn’t the water. After massaging her pussy lips, I slowly slide my finger inside her pussy. Jen was so wet and tighter than I thought, after all she did have 4 kids. She began breathing heavily and I slide my two fingers back and fourth. Jen said she couldn’t wait any longer, she had to have me. I grabbed her leg, moving up in the corner seat of the shower, I told her to take my cock and guide it in herself. Jen happily complied, as the head of my cock started to work it’s way in her tight hole, I almost came right then. It felt so warm and wet, plus the idea of having my wife’s mom just made me even harder. Jen gasped when I entered her completely, she said her husband was not near as thick as I was and had been almost two years since she had sex. I told her all that was about to change, as I thrust deeper inside her, my hands grabbing her ass, I knew I couldn’t hold out much longer. Jen said she was about to cum and so shoved my throbbing cock back and fourth until I felt her start to shake with pleasure, I told I was going to cum in her and she never stopped me. I felt my balls tighten and began emptying them inside of her. Jen tried not to yell out too loud but she can hardly keep quiet. Jen said she could feel the warmness in her, as I continued to slide my semi hard cock in and out. I finally pulled out and it was amazing to watch my cum drip out of my mother in law. We kissed one more time and she got out of the shower to go to her room. I finished my shower with a huge smile on my face, and started to think how and where I can have Jen again.
