I was wearing a really short mini skirt one afternoon while I was leaving class to walk back out to my car. It was breezy out that day and I had to hold one hand down on the front of my skirt to keep it from blowing around. Well, while I was trying to get my hair out of my face I accidently lifted my hand off and up went my skirt, completely exposing my butt cheeks and vagina for everyone to see. Some guys started whistling at me when they saw my naked butt and vagina flashing them in wide open view. I was so mortified. I didn't dare wear another skirt to school again.
