I am 24 years old and i teach a 6th grade class. on that day i was wearing a short skirt and a black thong. While i was walking to the front of the room to give instructions for a worksheet, i fell to my hands and knees and my skirt flew up and my whole 6th grade class saw my butt cheeks and black thong. Just then my co-worker/crush came into the room and saw it all too!
