haven't you seen a schoolgirl's panties peek out from under her skirt while she's climbing stairs? whether it's at a station during your commute or at various facilities. if you catch a glimpse, you think, wow, i'm so lucky. there might even be experts among you who mentally record these moments. and then, what about the panties that you see? do you get more excited if they're wedged in? or if it's a thong? or maybe you have a preference for the color of the underwear that shows? everyone has their own fetish points, but isn't this kind of panty flash really erotic? it's all about enjoying plenty of panty flashes with schoolgirls on stairs!
