elavator sex!

So I had a key to the elevator at school and my boyfriend and I were going to class as we are in different years anyway he didn't press the button and started hooking up, my cruches fell and made a loud noise it gave me a fright but not him. It got so heated he started fingering me AT SCHOOL IN A ELEVATOR...... the next day I needed to see a teacher and of course it was up stairs and my bf and I had another elevator ride this time we had sex in the elevator but he didn't cum and I got vaginal bleeding.... I soon gave the elevator key back as everyone says there are Cameras! I haven't told anyone and idont know what to do it was in the moment and it wasn't that good.
