TSP-103 - 48 high-class schoolgirls caught in the act, upskirt compilation

This is a completely staged AV. Where are the other cleaning duty students...? One girl just slowly, ever so slowly, polishes the same desk. Eventually, her hand movements become lewd and she starts smirking... It's more of a full panty reveal than a peek, so it has its own appeal, but I can't shake the feeling that it's a 'lazy, staged production.' I didn't want to write a bad review, but I'm leaving this criticism in hopes that the manufacturer will step up their game in the future.
