>>28956828Having a scat fetish in theory and doing it solo probably isn't as niche but I'd wager it's especially for women and the newer generations.
I'd wager a certain amount of people fantasize about seeing a girl shit a proper log like in OP's gif that comes out all firm and stuff. The real thing is obviously disgusting because of smell, uneven or liquid textures etc and I think it's only a few batshit crazy people that would even play with shit
With that said, I had multiple exes that joked a biiiiiiit too often that they wanted me to watch them poop and they also straight up asked me to hold their hands while they were shitting. Before that I would have chalked it up to a select few insane women that actually liked it, now I'm thinking there's indeed a group bigger than we think that like some parts of it at least. It is probably the single most taboo legal fetish though, so no wonder people who are even a bit interested would keep it to themselves
