Can't believe I hadn't seen some of these videos before. You have a very distinct style of shooting and I can see why you don't find many slips anymore with the high-waisted pants. Thanks for your vids they are all great.
Have you tried shooting any see-thru or upskirt shots? Thongs slipping outta pants while walking are nearly impossible to find let alone nowadays. Take a look at my thread. I have a few if you haven't seen. I will post a video of a thick asian girl walking up stairs in memory of this thread.
