I don't know how and where but I want to fuck a girl on our very first meeting

Few years back when I was at my home I got a call from one of my Batch Mate. She told me that our teacher asked her to call me and let me know about the important lecture which is to be conducted in the evening so please come to the Class. So I left for a class and when I reached there I found that there was no class but she was planning to propose me and that was the best moment I felt and after that she got her first ever Sex in the class where I made few of my friends stand outside to keep us alert if anyone comes there.
