Growing up as a kid, I lived about 2 blocks from my aunt's house. They had a micro farm of about 35 acres, just perfect for playing all day without any interference from adults. My oldest cousin was 16 and she had twin sisters my age, 11. We used to run the farm every day inventing games and having good farm fun. Of course we had our share of watching the animals too. One day after watching a particularly horny bull service three cows I was full of questions about life. I asked my older cousin why his pecker got so large and why he was snorting and slobbering all over the place.
She said if I really wanted to know she would tell me but I could never tell our parents. Of course I agreed, so we sent the younger kids to the barn and we went out into the fields. Bordering the last pasture was a nice stand of trees with a lot of very thick underbrush. We had hidden here before and knew nobody could see us. She told me to take off my clothes and shoes. I replied only if she would. In minutes we both stood there naked as could be. I was really interested in her budding breasts and the hair patch between her legs. My cock started growing right away, something I had experienced, but could not explain. She told me it was natural for a guy to get bigger when he was excited or saw naked women. She had me lay down and began to gently stroke my rock hard tool. This is how the bull makes babies she said, when he puts it into the cow. Soon you will shoot your cum and thats what makes the babies. My cock was rock hard and I was thrusting my hips up to meet each stroke. It was only minutes until I erupted in a fountain of cum, thrusting my hips high and shooting it all over my chest. Thats the baby stuff she said. I knew now why the bull was snorting, I was breathing heavy and snorting too. Next time I will show you where to put it and how to please me too. But remember, you can never tell your parents or mine. More secrets next time.
