Sex Education, Sort Of

We were 7th grade, and a conversation got heated between my mother and father. It had to do with sex. My mother got angry and she told me and then my brother. To get naked right there in front of my parents. Until we were both completely naked. I had to look at my brother's penis, he looked at my pussy.

Now that we had seen the other sex naked, she told us to stay virgin till we finished school.
