Hard on in Class

I was in my nineth grade English class, and we were reading 'Ivanhoe.' The teacher, Miss Smith, would call on differant students to come forward and read to the class. My buddy gave me a dirty book and I was reading it instead of following along with the reading. While reading this book, I got a big ass hard on. As I read, I thought I was going to bust. Then it happened. I was called upon to come in front of the classroom to read to the class. I tried to beg off, but to no avail. As I came forward I tried to hide my erection. My close friend, Lavera, who is Afro-American, saw my erection and winked at me and started to giggle. That got me all mixed up in my reading. Then she started to rub her left breast so the teacher didn't see her. I wanted to rub her tits myslef. I can't say if others in the class saw my erection; I didn't look at them when I sat down. After class Lavera wanted to know what I was reading to get a hard on in class. I showed her the book while she leaned close, and stroked me through my pants while reading some of the pages. I told her I was going to explode. And she said, 'Okay, cum for me.' I came so hard that the cum was all over my stomach and started to run down my croch. 'You better go to the boys lavatory and clean up,' said Lavera as she walked away with my book. She could jack me off anytime, but it never happened again.
