Sis's Friend Gave Me a Treat

I had just graduated from high school and we had a celebration at my house. I am one of 11, so there were a lot of my sibling's friends and spouses there. It lasted hours and most people started leaving at 2 o'clock in the morning. Once most of them had left, I sat down on the couch to relax and my sister's friend sat down with me. She told me how proud of me she was and that I deserved a treat. One thing lead to another and we ended up having sex right there on the couch. It was so great.
