It's just a 'crude' way to allow air to flow in those areas without having to actively stretch and hold the position yourself.
Females who wear closed shoes [especially when they have soft, tender feet] do it more than you might imagine. Just... not with rocks.
Not that I don't appreciate your post, but these pics are all recent posts from danbooru (or gelbooru, whichever you prefer) and can be easily got from there.
What the topic needs is posts of rarer images and video clips which would be hard to find otherwise.
Agreed. I'm looking through an anime called Amaenaideyo for stuff. I'll post if I find something.
how come I can't ever remember a scene in an anime where a female character is painting her toenails?
Because most anime don't focus on scenes where a chick is sitting in her room doing something mundane like that.
thank goodness for that.
painted toenails are creepy.
