During an important class test, I wanted to pee so bad! A strict teacher wouldn't let me go to the toilet during the test. I felt very bad, because every minute I wanted to go to the toilet more and more. I couldn't sit still in a chair and fidgeted because my bladder was full! Eventually, I couldn't restrain myself and peed a little right into my panties in a skirt! I was very embarrassed and I ran out of the classroom, but the toilet was closed! My bladder was full and I couldn’t hold my pee anymore, I pissed a lot! My pussy was so wet and I was so ashamed!
