Well I was in 8th grade when this happened. It was the last period of the day I could not wait to go home. That morning I was running late to school so I took a shower, threw on a skirt and a pair of panties that were a little to big for me but I really did not have time to change, so I went the whole day with this big panties that were so uncomfortable.
So 8th period came I could not wait to go home. I had massive books to carry on the way back, so as we made into the hallway I feel my panties start to fall I said to myself "oh my god please not this", so at this point I tried to run into the bathroom right near the classroom, flying right into the doors, fell over and to top that off my panties were down to my knees.
I locked my self in the bathroom stall for about an hour until the coast was clear. I was called big drawers for that whole week.
