I just had a great upskirt experience yesterday.
In the UK we're having a massive heat wave, and I was visiting London to see a friend.
As I was waking down the street a girl gets out of a taxi in front of me wearing only a pink skirt and what looked like a bra. In the middle of the day! It looked like maybe she was on the way back from a hen do or something.
She happened to be walking the same direction as me so I hung back a little bit so I could watch from behind.
Then the holy grail happens. A gust of wind appears and blows her skirt up, revealing that she's not wearing any knickers. Bare bum
