These print panties just reminded me of something I keep meaning to find the name of but always end up putting it off and forgetting about it.
Way back in the 90's when we first had access to internet at a relative's house one of my brothers went about checking out all those old freebie image and video sample galleries found on most porn sites of the time. This included hentai also.
Given it's popularity back then most sample video clips from these hentai pages were of La Blue Girl. There was one that stood out as being weirder than the others it played out similar to a silly comedy fanservice series from the 2000's. The whole thing was in Japanese with no subs.
The scene was in some store with some guy on all fours checking the bottom shelves when he peers through to the other side and spots a girl squatting there unknowingly flashing her panties at him.
Some weird looking old dude appears next to the guy and makes some comment that pisses him off and he stands up yelling which startles the girl causing her to make a run for it. Only she trips over her own feet and falls flat on her face again showing off her panties with some cartoon print on the back.
I don't know why but once in a blue moon I end up remembering that clip and for some reason it bothers me more and more each time that I can't put a name to it.
