Quite a while ago I tagged a few posts with the pussy_floss tag. Bit later I also saw another person tag a pic or two. The tag was removed since then though and replaced by the wedgie tag on at least one of the posts I had edited. Wedgie and pussy_floss aren't the same thing though. Pussy_floss specifically relates to fabric, usually a thong or a leotard, being completely inside the pussy.. through the pussy? Hence the "floss". I've looked at the wedgie tag and it doesn't relate to pussy_floss really. That's often just a camel toe or y'know, a regular wedgie, shown from the back.
Here gelbooru.com/index.php?page=post&s=view&id=7738842 the tag was removed and replaced by "wedgie" and "pussy_peek".

I know tags shouldn't be diluted, so there's 500 different cum tags and shit, but idk.

To find what you are looking for you can try:

Wedgie + cleft_of_venus
Frontal_wedgie or between_labia

Or like this one gelbooru.com/index.php?page=post&s=view&id=4425906 which now has frontal_wedgie as tag.

I wasn't specifically asking for that, I was wondering, or rather asking, whether pussy_floss should exist at all. Frontal_wedgie, wedgie and combined with pussy_peek seems kinda rough. Frontal wedgie is just wedgie still.

Try wedgie + cleft_of_venus I personally maintain the CoV tag. You will find plenty of the stuff.

It should exist. But probably it doesn't because of danbooru. Or taggers not putting the effort.

K, I'll use that as future tag combo then.

Stuff is pretty sexy, but niche. Taggers have to put the effort.
