I grew up on a farm. One day when I was 5 years old, my sister, who was 10 at the time, and I were out exploring in one of the pastures. A herd of cattle was grazing nearby. The bull started chasing one of the cows and when she stopped he mounted her and stuck his big long dick in her and began thrusting vigorously in and out of her. I had no idea what we were witnessing so I asked my sister what was the bull doing to the cow. She explained they were having sex in order to make a baby calf. The bull filled the cow with his semen and she will become pregnant and in a few months will give birth to a calf.
She went on the explain that people also have sex when they want to have a baby. She told me how boys’ bodies are different than girls’ and how they fit together when they have sex. Watching the bull mate with the cow must have gotten my sister excited because she asked me if I would like to have sex. “Do you want us to make a baby?” I asked. She laughed and said that it would not be possible for us to make a baby because our bodies were not mature enough, but that we could still have sex. I asked her if she had ever had sex before and she said that she hadn’t but a friend from school who had had sex told her about it and how to do it. She said it was a lot of fun.
I knew my sister really wanted to have sex and I trusted her because she always looked out for me so I agreed. She then undid my pants and slid them down and started fondling my dick rubbing the skin back and forth. That was the first time another person had ever touched my dick and played with it in that manner. It really felt good and my dick immediately got hard. She then took her pants off and laid on the ground and told me to lay on top of her. She took my dick in one hand and guided it to her pussy. She placed her other arm around me and pulled me tightly to her pushing my dick into her pussy. She then told me to start thrusting in and out like the bull had done.
Her pussy was warm and wet inside and my dick easily slide in and out. I told her it felt really good inside her and was very enjoyable. She said she was also enjoying it. After about 5 minutes of thrusting I felt an odd but very pleasurable sensation beginning to build up in my groin area. It only added to my pleasure so I continued humping her for about another minute when suddenly, like a violent explosion, the most intense sensation I had ever experienced engulfed my entire being. I was having involuntary muscle contractions, my breathing was heavy and I was gasping for breath and I felt all the energy drain from my body. I felt like I was going to pass out. I had no idea what had just happened to me and I was frightened. I struggled to my feet and began crying. She put her arms around me and hugged me tightly to her breast and calmly assured me that I was OK, that I had just experienced my first orgasm and that the feeling would soon go away. She was right, the intensity of the sensation soon subsided leaving me with a feeling of sheer ecstasy that I knew I would want to experience again.
She then told me that we could never ever tell anyone about what we had done or we would get into serious trouble. I agreed and we made a vow to each other that this would be our “little secret” that no one else would ever know about. She then told me that we could have sex anytime and as often as we wanted. I told her I would like that and asked if we could do it again right now. We actually did it twice more then had to go home as it was almost time for dinner.
After that we had sex several times a day every day. This lasted until she left home for college. Even then we had sex when she came home on weekends and breaks.
After graduating from high school, I enrolled in the local community college where she was now working in the HR department. We got an apartment near campus “to share expenses” but it was actually our “sin den”. It was a two bedroom unit to deflect any suspicion although we only used one. We watched porn, read sex books and experimented with every sexual activity and position imaginable.
Our incestuous relationship lasted 17 years. But like all good things, it had to come to an end. She had gotten serious with a man she had met and wanted to start a relationship with him. Also, a girl in one of my classes told me she was highly interested in getting to know me better. And with that our relationship came to an amicable conclusion.
We’re both happily married now but neither of our spouses know or suspect anything of our past. My sister and I are as close as ever, except for the sex. One day we reminiscing about our relationship and estimated that we had had sex over five thousand times.
