I was at my friends 12th birthday party. His name was Max, and his sister’s name was Sarah. He was turning 12, and he had a twin sister. That meant that there would be his friends(males), and his sister’s friends(females). His party was to be at a swimming pool. When I arrived I was greeted by Max, my friend, and his sister, Sarah. Soon, the rest of Max’s friends and Sarah’s friends showed up. The boys went to the locker room to change and th girl’s changed in ther locker room. We all swam in the pool for a while. All of the people there were from my school. As I was swimming and playing around in the water, I couldn’t help but look at Sarah’s friends in their bikinis. I soon noticed one of her friends that was the hottest and sexiest. Her name was Mary and she was slim, curvy, brown-haired and had large tits for a 12 year old. She was checking out some of the boys and I saw her slip a finger in her bikini bottom. She was wet, and not from the water. A few weeks earlier I hd seen her in a deserted corner of our school with an entire virbrator in his cunt. I had only talked to her a few times in school but I was determined to get in his pussy. Before I made my move, I got a boner by checking out some of Sarah’s other friends. There were about 13 of them, and they were all sexy, but nothing compred to Mary. When we decided to go to the diving board, I was sure to go to the back of the line where Mary was. I slapped her butt. She smiled, I knew she was a whore after hearing Sarah talk about how much she masturbated a few days before.
