I accidentally caught a glimpse of my classmate's panties. I rarely encounter such lucky panties on the streets or on the stairs at the station, but now, on campus, right in front of me! I can't help but stare... but the person is a girl from my class... if I get caught, it'll be bad... but, but, my emotions are running wild, ignoring the command to close my eyes. What should I do... if she turns around, I'll get caught... Ah... I got caught after all! Huh!? Why is she smiling? Maybe she's also...
