trapped

I am only in middle school and I did not even know it could happen. During a mock congress meeting at school, the bill authors were talking and this boy sat next to me. He put his hands on his genitals and began masturbating next to me. He kept looking at my breasts and nudging me. I scooted away and he only moved closer. The room was packed with other middle schoolers and we were not allowed to leave so I could not leave. He then ran his hand from and inch under my pencil skirt down my leg and stroked my foot. He began squeezing it and when I looked at him, he grabbed the keychain from my nearby backpack and asked me where I got it. He had asked that question earlier that day. Later, he continued to sit next to me and rub my knee and even caressed my ear. I have to go to school with him.
