My sisters were having a sleep over. Some of the girls I didn't like but there was one I had a crush on. I saw them in their pajamas and it turned me on. The next morning I couldn't take it any longer. I was in my bedroom masturbating. It was coming out of me when I heard the laughter. They had taken the register off and were peeking at me through the holes. It was too late. I couldn't stop myself till I was done. Later my mom called me for breakfast but I didn't want to go. My dad made me. The girls had these goofy grins on their faces and my parents kept asking what it was all about. It was the worst day of my life ever.
