I have been living at my parents house while I'm going to college. My mother and father had always gotten along pretty well, and have been married for twenty years, but I suppose that mother started feeling a little bored. Well, the two of us started enjoying flirting with one another and being teasingly affectionate whenever my dad wasn't around. It was a little daring and fun and we both enjoyed it. We joked a little bout our going all the way together, and how daring that would be. One morning, after dad had safely gone to work, mom and I started fooling around. It was great and a lot of fun. We got naked and that was very exciting, and it sure gave me an erection, I can tell you! Mom loved it. My mom's been fixed, so there was no worry about her getting pregnant, so it as easy to just go ahead and have sex. It was so wonderful to fuck her, and mom loved it. After that, we began having sex several times a week, and we would spend a couple of hours fucking and enjoying every minute of it. Then one day dad came hom unexpectedly and almost caught us. I was laying on top of my mother on the bed, and my erection was in her vagina, and suddenly we thought that we heard a car. We got up, and there was my father in the driveway! We hurriedly got dressed and ran downstairs and tried to act normal. My father had just forgotten something was all, in five minutes he was gone. Mom and I both about died!
After that experience, mom and I realized how careful we had to be. We started to cut back on our fun, although a year later the two of us still cautiously enjoy making ove henever we can.
