When I was 15 I was sitting at the beach with some friends playing guitar and singing with a group of older boys (18is) not far away, when two of them came running over, giggling and completely naked. He stood in front of me and told me to play a song again and proceeded to keep insisting until I complied and played it again even though I was extremely uncomfortable. I only played it because I wanted him to go away and didn’t want him to get angry or come too close to me or my friends. The other guy filmed the whole thing without our consent. After that they ran off laughing like it was the funniest prank they had ever pulled.
