This is such an under-rated category. I was thinking to collect some "scenes" and edit girls into them.

elevators
stairs
escalators
changing rooms(clothing stores)
locker rooms(communal)
hallways(especially hotel etc)
anywhere carpeted is a bonus
bus/train/etc especially going into the seat but floor is still nice
cinema

intentional use of bathroom floors is also nice, but inherently less risky and thus less exciting
Lately I've found a few of girls pooping into men's urinals and I like that because they can't be flushed.

Ironically a lot of this is surprisingly easy to find 3d girls doing especially drunk girls. Need more 2d material!

One other thing, don't confuse this for generic desperation. Girls might need to go, but you have that extra DNGaF factor(and often sneaky factor too). Generally this isn't panty pooping either. This is intentionally leaving your mess to be someone else's problem!

This is the best fetish.
