http://www.jade-net-home.com/products/181: Virtually every upskirt video of women squatting down with sexy lingerie is staged, made to look real. You can easily tell when you see high school students wearing transparent thongs, with pubic hair showing through. They're all made to get us horny as hell for sure, but they're still fake.
http://www.youplanning.jp/dvd/detail.php?no=V062090: High school students walking up stairs really slowly like that? Sitting down right in front of a stranger with their legs wide open, pretending to do something on their smartphones? Does this really look real to you?
http://www.h2.dion.ne.jp/~trad.h/A-guide-top.html: The same goes for all these women with no underwear, squatting down provocatively. If these really look real to you, then you probably haven't seen enough of the best real ones yet.
Of the ones I posted a bit above yours, all of them are staged except KEPMS, PYNMS and probably TOP-016, which I don't own but looks real from screenshots.
Here are some of the very best 100% real videos of upskirt panties ever made where the women are quite aware that they might be filmed, but don't care anyway:
http://xhamster.com/movies/2717461/encoxada_e_upskirt_top.html: Around 5:05, you can clearly tell that she's aware that there's something weird going on, but she still leaves her legs wide open until the very end.
http://xhamster.com/movies/5655134/upskirt_very_short_skirt.html: This famous one from Murziq features the shortest skirt ever without showing the panties unless you're looking up. Blood_Doll might like this one since it also has a bit of wind blowing her skirt up. Anyway, she's looking at the camera all the way from the beginning, so she knows she's being filmed, but also knows she can't do anything because her skirt is just too short.
http://voyeur-russian.com/upskirt.html?list=104: This famous one from December 11, 2004 has a hottie on top of a boat, wearing a white transparent thong under a very short skirt that also happens to be very loose (my favorite type of skirt) that gets blown up a bit by the wind. Around 1:05, she notices the camera. But you won't believe what she does next where she puts her right foot on top of the lower railing so that we can get a perfect shot of her front thong, and it's all 100% real.
Bonus 1. The woman doesn't know she's being filmed, but the technique is the best ever:
http://freakshare.com/files/081lyf0o/up_manlinp_MVI1429.rar.html: She's wearing transparent panties, my favorite type of lingerie. And the guy shines a light under her skirt to get the best possible shot. I just wish I could clearly see the front with pubic hair.
Bonus 2. This is undoubtedly the hottest babe ever upskirted that I've seen so far:
http://100upskirts.com/play/i117f/Inspiring+upskirt+with+stunning+babe+walking+with+bf.html: Even women are turning their heads, staring at her sexy body. She's wearing my favorite type of skirt, and she gets repeatedly upskirted. She technically doesn't know that she's being filmed, but she definitely doesn't care at all whether anybody is looking up her skirt while she's walking up all those stairs. This would've been my all-time favorite, if she wore the same type of panties as bonus 1.
In summary, the Japanese know that there are plenty of men out there looking for these types of upskirt videos, so they stage a lot of these and do their best to make them look real. And some are real like the ones I showed you above, but they're rare because there simply aren't too many women out there who don't mind random men looking up their skirts. I hope this helps.
