Skinny Dipping With A Girl

Many years ago, my family took a vacation to a rural area of Australia to visit some old friends. I was not very excited for this trip. It was summer, and I wanted to take a holiday near a beach, not in a hot, deserted place. The drive from Sydney took all day. My parents and I packed the car and left our house at sunrise, and we didn't get there until almost sunset. I got of the car to greet my parents' friends. They were in their early 40s, and had a 13 year old daughter, Abigail. She was pretty in a plain- girl way - natural face, curly blonde hair and a figure that wasn't too skinny or plump. We ate dinner together, with Abby sitting across the table from me. We kept glancing at each other from time to time. When dinner was complete, my parents and I said goodbye to the family and went to a nearby motel. Abby's family wanted us to stay at their place, but I think my parents wanted me to have some privacy and not share a room with anyone. Over the next week, we explored the town (and there wasn't much to see). We spent most afternoons and nights at Abby's house. She and I became friends through our mutual love of reading. On the second last day of our stay, Abby suggested that she and I go swimming at a nearby river. I wanted to go and we asked our parents. Due to its proximity to the house, we didn't need any supervision at the river.  We went in the afternoon - Abby in her light blue bikini and me in my long black shorts. The area was full of trees and hidden from view from main streets. We swam around and playfully splashed water at each other. After two hours of swimming, we began to get tired, and so we got out of the water and sat on the riverbank. To my surprise, Abby took of her bikini to let it dry off, revealing to me some small breasts and an almost smooth vagina with just a bit of blonde pubic hair. She noticed me glancing and cheekily said ''we've all got bodies, what's the big deal?''. I wasn't sure what to say, so I just sat on the grass and continued to stare at her. I knew it was impolite to look, but this was the first time I had seen a girl naked and I couldn't look away! She left her bikini on the grass and headed into the water. After a few minutes of building up courage, I stripped off my shorts and entered the water quickly. We were still too tired to swim, so we just stood in waist deep water looking at each other's body. Suddenly, Abby pointing to my crotch and I looked down. I had a boner! I didn't even notice as I was too busy thinking about Abby's nude body. ''Need to jerk off?'' she asked me. All I could do was nod. ''Yeah, me too!'' she squealed and began to finger herself. I was a metre away from her and could see everything fairly clearly. The way she rubbed her wet vagina and the way her fingers disappeared and appeared inside it got me excited! We were roughly the same height, so both our privates were just barely visible above the slightly murky water. As Abby continued to masturbate, I started to stroke my own penis. It didn't take long at all for me to explode. In just a minute or so, ropes of sticky white cum came out of my penis and floated on the water near Abby. The sight of me ejaculating caused Abby's body shake and her hands gripped her legs, near her vagina. She had a look of ecstasy as she orgasmed, and it made her weak enough that she fell to her knees in the water. I went over to help her up and we returned to the area where our swimsuits were. We continued to chat in the nude on the lushious green grass. After today, there was only one day left with Abby and her family. I knew what I wanted to do with her again.
