This story is a work of fiction. While I myself fantasized about something like this happening when I was in High School, it is only a fantasy.
It was my senior year in high school and my grade point average was barely getting by to be able to graduate. I was 18 and in my second semester. My grades were good enough to graduate in all but one class, Biology. There were a couple of other classmates that were in the same predicament as I was and had resorted to studying together in order to bring our grades up.
One of my classmates with low grades was a girl I was friends with. She was kind of shy, like me, and a bit naïve, like me. By physical appearances, both of us were sort of 'average'. I was 5'5", light red hair, and average build. From what I noticed in the showers in gym class, I was a bit bigger than most of the guys in my class.
Carol, my friend in Biology class, was a little shorter than me, a brunette, with what I guessed to be about a 34B cup bra size. Her physical shape was the same as mine, about average. She had a nice smile and great personality, which is why I decided to team up with her for after-school Biology studies.
With our schedules, the weekend was about the only time Carol and I could get together. This particular Saturday, Carol and I were going over the chapters in reproduction and genetics. There was a big test coming up on Tuesday so we had planned on putting in a lot of time, starting mid-afternoon on Saturday. Because Carol's brother was going to have a bunch of his buddies over to the house, watching afternoon and evening TV, the only place to have some quiet time to study was at my house. My parents kind of liked Carol and didn't mind having her over. My parents had planned on being at a party until late in the evening and by 5:00pm Carol and I had the house to ourselves.
As Carol and I reviewed the genetics part, we went though the genetic possibilities of how I got red hair from my dad instead of brown from my mom. For Carol, it was somewhat the opposite. She ended up with hair color more from her mother than her dad. While going through a list of things we each inherited from our parents, Carol confided in me that she was glad her boobs were more like her mother's than her grandmother. I've seen her mother and I would guess her mother is about a 35C, while her grandmother has nothing up top at all.
I had seen my dad once when he stepped out of the shower, and I was pretty sure that was one of his features that sealed-the-deal for getting married. Without thinking, I commented that I must have taken after my dad down below. I almost cringed at the thought of what Carol must have thought at that revelation. For what seemed like an eternity, I watched the wheels in Carol's head turn, thinking about my last comment.
Finally, she ventured that she had heard some of her friends talk about their boyfriends but couldn't quite imagine what a penis really looked like for real. Our biology book only had a crude drawing and Carol had never seen a penis for real. Since there would be questions on the big test on Tuesday covering reproduction, I had an idea that would help us both.
Carol had never seen a real penis and I had never seen a girl's breasts or crotch, I suggested that if we showed each other our private parts, it would help give us a better idea of what the biology book was talking about. It took a few minutes and some additional coaxing but she finally agreed. Her one stipulation was that I go first. I would have liked to have seen her go first but figured me going first was the only way Carol would go through with it as well.
