How can you be my father? She asked me. I layed there next to her, my cum dripping from her tight young pussy, trying to think of where to begin. I started with the wedding. My dad and her mom were married when I was 15. They had gone on their honeymoon, and when they came back, it was time for my summer stay with my father. I was there for only a few days when he got called away on an emergency at his job. He had to fly to the Midwest, to help them with a factory issue. He ended up being gone for 4 weeks, leaving his son and young bride alone together. My step-mom was only 26 at time, so she was right in between my dad and I in age. At 15, I couldn’t help but be attracted to her. So, while I was in my room late at night, with my step-mother in the next room, I often masturbated thinking about her. One night, she came in late to check on me and caught me just as I was cumming. She stopped in shock, watching me intently as I came. Then she quickly pushed out of the doorway and closed the door behind her. I was afraid I was going to get in trouble, but the next day went by and she didn’t say anything. The next night, I didn’t see or hear anything as I once again masturbated thinking about her.
The next day went by without much happening. We went through our normal day, and never once did the subject of what happened come up. But that night, something changed. As I was in my room masturbating, I looked over and noticed my door was slightly open. I couldn’t see the other side, but I knew she was watching me. I turned to make sure she had a better view of what I was doing, and it seemed to work. After a few minutes, the door opened and she walked in. She was wearing a very sexy nighty, probably something she had worn for my dad. She kneeled in front of me next to the bed, and without saying a word she took my cock in her hand and started stroking it. She looked up at me and told me that I had to promise not to say anything to my father. I, of course, agreed, and with hardly any hesitation at that point, she lowered her head and took my cock into her mouth. I came almost immediately, as this was the first time I had ever had a woman suck my cock. She started to look disappointed, but she took my cock back in her mouth and started sucking and stroking my cock. To my surprise, I was hard again within a few minutes. Once I was hard again, she looked up at me and smiled wickedly. She didn’t say a word, but pushed me back on the bed and climbed up on top of me. She straddled me, and took hold of my cock, guiding it into her pussy. She slowly lowered herself down onto my hard cock. She sighed in pleasure as she let herself all the way down on my cock. She started off slowly, but was soon bouncing up and down on my cock wildly. Thankfully, because I had just cum, I was able to last quit awhile. She slid off me at one point and told me to get on top of her. She spread her legs and guided me into her. As I started to move in and out, she told me to let her know when I was going to cum. Not knowing what I was doing, I was probably pretty sloppy, but she seemed to be enjoying it, and so was I. I must have been doing something right, as soon, she was crying out as she started to cum. And then, I started cumming as well. But, instead of pulling out, my body told me to push deep into her, telling her I was cumming a bit to late. But apparently she was okay with it, as she told me to fill her pussy with my cum.
I collapsed on top of her, and we just laid there for a few minutes. After a few minutes she told me she should get up, and she thanked me, and reminded me not to say anything to dad. I again agreed, and was soon asleep. The next morning I came out and she was working in the kitchen. I was a little shocked when I saw her, as she was wearing a really tight tank top, and a very short skirt. I could see from my seat at the table, that she wasn’t wearing any panties either. She must have guessed what I was thinking as she turned around and smiled. She told me how my dad liked her to not wear panties, and how he would come up behind her when she was doing dishes or something else and take her hard from behind. She then turned back around and started working on the dishes again, her ass pushed out a bit more than before.
I moved behind her, pulling down my pants and stepping out of them. With my cock in my hand, I moved towards her, but had problems, as I still didn’t really know what I was doing. She reached between her legs and took hold of my cock, guiding me into her dripping wet pussy. I pushed all the way into her, and she gasped in pleasure. I grabbed her hips, and immediately started pushing in and out of her as hard as I could. She was moaning in pleasure, telling me to fuck her harder, and to pull her hair. I did as she asked, and awkwardly pounded into her. Soon she was screaming in orgasm, which made me cum hard deep inside her. After a minute, I pulled out, and she suggested we get cleaned up.
This went on for the next couple of weeks, us fucking whenever she felt like it, all through the house. I spent most nights in bed with her, either in her and dad’s room, or in my room. I didn’t know at the time that she was not on birth control, or anything really about a woman getting pregnant. Then my dad got back from his business trip, and that was mostly the end to our little affair. We did fuck a time or two when he was at work, or out doing something else, but not like we had been while he was gone. Not long after my visit, they announced that she was pregnant. I was a little shocked, but didn’t think too much of it at the time. It wasn’t until three years later, when I was again at my dad’s while he was gone, that she admitted my ‘sister’ was actually my daughter. This time, he was again away on business, but my step-mom had asked me to come stay with her during his trip. Dad, of course, thought it was a good idea for me to spend some ‘quality time’ with my step-mother.
This time around though, was quite different. It had been three years since our first time together, and I had gained some knowledge and experience since that time. So, I was able to please her a bit better, while also being a bit more careful, at least the first night. It was also a bit different, as we had to be more careful, since my sister/daughter was there most of the time as well. However, there were a few days she spent with her grandparents.
Our first night after my dad left, I slipped into her room. I pulled the blankets off her, and slid up between her legs, moving my mouth down to her already wet pussy. I licked and fingered her until she came several times, then I moved up her body, licking and sucking along the way, stopping for awhile at her tits to suck, lick, and bite her nipples. By then she was begging me to fuck her, so I did. I slid my cock into her slowly, until I was all the way in, then I slowly started to move in and out of her. It wasn’t long until I was pounding into her hard, groping her tits hard, and kissing and biting her neck. She was soon cumming again, and I felt myself getting close. Not wanting to make the same mistake I did three years earlier, I pulled out and came all over her stomach. She didn’t say much about it, but we soon were both asleep.
The next afternoon, while the baby was napping, I found her in the kitchen, in much the same manner I had three years earlier, with a short skirt and tight top. I moved behind her, slipping my hand between her legs and roughly rubbing her clit, slipping my fingers inside her as well. When I knew she was ready, I pushed my cock into her and started taking her hard from behind. I reached around her and started rubbing her clit as I fucked her. Soon, she was having an amazing orgasm, and I was sure she was going to wake the baby. I felt myself getting close, and she turned her head as best she could and told me to cum inside her, that she needed my seed deep in her pussy. It was all I could do at that point to keep a hold of myself, as I began to thrust harder into her, until I finally pushed deep and released my cum deep into her. We got cleaned up just in time as the baby woke up.
That night, she had me sleep in her bed with her. I was on top of her, pumping into her missionary style, when I was getting close to cumming. She whispered in my ear and begged me not to pull out. She begged me to cum inside her. She told me she wanted me to give her what my father apparently could not. Something about her begging spurred me on, and made me want to give her exactly what she wanted more than ever. I pushed deep and hard, pumping into her as hard as I could. I brought her to an amazing orgasm, before finally pushing all the way into her and releasing everything into her. I came harder and longer that night then I ever remember, before or since. It was an absolutely amazing feeling. We spent another week fucking where ever and when ever we could. It was just a couple of months later when she again announced that she announced her pregnancy.
After finishing my story, the young woman I had known as my sister, looked a bit confused. She asked how, if he couldn’t get her mother pregnant, how did he manage to get her pregnant. I told her I did not know, but there could be any number of reasons, but I personally did not know enough to know for certain. All I knew was that my father had managed to father at least two children prior to marrying my step-mom, and had obviously fathered at least one since then. . But, likely we would never know for sure….
