This was round about when I was 14 and it was a school day. On that day we got to miss our first 2 lessons so I used those extra 2 hours to get some sleep. I woke up and it turns out I over slept and was already 10 minutes late for school (no one was in so no one could wake me up). I panicked and took my pj's off as fast as i could and then took my dirty undies (I wear underwear while I sleep) and took out my school uniform and tried to put it on as quickly as possible. Then I put on my shoes and grabbed my school stuff together put it in my bag and ran to the bus stop. I got lucky that the bus only just turned up so I didn't have to wait another 30 minutes for the next one. Once i sat down I noticed it felt a little different than usual but I ignored it and just waited till I got to school. I arrived at school and rushed to my class and said sorry I was late, class was nearly other so the teacher was really annoyed with me. I was annoyed with myself not being able to take a shower today man my arm pits were sweaty and I smelled bad. It was the end of the lesson and usually when we get of class some of the people in my class usually whisper to me nice knickers Amy or something like that (my underwear is nearly always showing in my school uniform) but this time 2 guys whispered to me "Nice butt crack Amy." I blushed and rushed to the bathroom and quickly checked down my trousers. "Oh no," I said to myself realizing I am not wearing any underwear today. "I should of at least kept the ones I had on yesterday I smell enough as it is." So I went to next lesson and once we got into class I sat right at the back so no one will see my butt crack and waited for the lesson to finish. The lesson finished and it was lunch time, I was worried that someone was going to pants me or try and give me a wedgie. It was nearing the end of lunch and nobody had tried anything like that yet but out of nowhere one of the boys who saw my butt crack pantsed me where i was hanging around with my friends. At first I didn't notice anything but then I noticed my friends looked down at my crotch area and I was thinking what they were looking at. So I looked down and noticed my trousers on the floor and I screamed, then I heard some boys wolf whistling behind me and saying "Nice ass Amy." I blushed bright red and then pulled my trousers back up and then ran out of the school not caring that I have one more lesson I was too embarrassed.
