Does anyone know of any videos out there that linger on the aftermath a long time? I like after the woman is covered in slime and doesn't wipe it off but then the camera tracks them after while it just drips. Anybody know of any videos like that? Bonus points if walking around outside.
Don't think this is exactly what you mean, but here's playing around in the mess after a scripted sploshing. The actual scripted sploshing lasted close to an hour so it might be considered "lingering" if you include that time Unfortunately, it is a bit too risque for YouTube standards.
Are you specificallty looking for a long aftermath after total messing has been achieved, or just during the scenes in general? A lot of our messings are fairly slow, starting with small amounts and then building up to total drenching in gloop, so there will be significant periods when the girls are quite messy, with stuff leaking through and dripping off their clothes, but still with clean areas too, and they'll be moving about and doing things to the other girl(s) while ignoring the steadily increading mess on themselves. A few example - three girl scenes are particularly good for this kind of "ignoring the mess on me while adding to the mess on you" thing.
Love you, too
