The infamous “upskirt” has become somewhat of a cultural phenomenon in Japan, so it’s only natural that those silly azns would eventually come out with Puff!, an iPhone app that lets you see up women’s skirts by flicking or blowing on the screen.

Here’s some semi-NSFW vids showing off some panchira action.

There are currently only three girls to chose from, all of whom are gravure idols. There’s Yurika Kurosawa, Aki Suzumori and Kana Osumi.

Download Puff today and flick, blow, and fap your dirty little heart out. You perverts.
