Happened during my commute to work yesterday. There was this office lady, probably in her late-20s, walking some 15-20 meters ahead of me in the underpass. Her skirt was relatively short; length till mid-thighs.
As we approached the escalator, I thought I would have a good chance to catch a upskirt since there is nobody between us (to obstruct my view). Alas, I timed my steps inaccurately by walking abit too fast, and the angle of view was no good..
Just I thought I wasted a rare chance, the gal started to walk up the escalator. Gradually the angle of view got optimum and tada! White, tight panties. Heh.
