As stated Rimworld and Sims are fun if you like context and setting to be turned on. Definitely applies to me, a still image barely gets me going but a connection is really valuable. But those lack content and I'm obviously saying modded, vanilla games 100% don't go there.
I'd love to try AI Dungeon for zoo and I think I considered it even in like 2020 but I thought it silently tracks users, surely for model improvement but I feel I can't trust there to not be some nerd on the dev team who'd ban/snitch, someone said long ago not to use it for anything illegal but maybe I'll check out its privacy settings. They can take truly anonymous data from my session I just don't want to get in trouble off something dumb, haha.
There's a text based with simple image game called Degrees of Lewdity where you play as a high school student, the intro claims they're 18 just for posterity though I think it has a certain target audience nevertheless. Anyway, I lost a fight to a dog and it forced my character to penetrate it, imagine my surprise and instant approval at a game having a power bottom zoo encounter.
We could definitely use more zoo games and animations even if we have to call them feral furry or something. <3
