Hopping in our TARDIS, I am travelling back a year, and resurrecting something brought up by Halite a year ago ...
With the advent of the penis_outline tag to *ahem* cover bulges that show enough junk to warrant a rating:e, I wish to re-visit the possibility of a 'pussy_outline' tag for images that feature something that is beyond simply camel_toe.
In this one, the labia, clitoris and even vaginal opening are outlined, and is nudging the boundary of an explicit rating.
Images like the above are not your garden-variety camel_toe, and may need further *cough* coverage.
(I came up with quite a few results searching camel_toe pussy solo, btw ...)
