I made an account just to make this comment! Would be pretty cool to see each character have fetish likings or something. Like as you fatten them up they gain new fetish likings, like favorite foods, and favorite foods could provide extra calories or something! As well as just overall fat fetish related traits! You have normal traits and likes yes, I just think it'd be fun and hot for like a stage 2. Where you gotta be a proper feeder for them.
Thanks for taking the time to do that. :)
I would like to add more feedism-focused content & your idea could work well with that. Perhaps a new feeding system at the home locations where you can cook/pick exactly what foods she will be eating, with the right combinations for each particular girl unlocking the best bonuses.
