Thank you, I'm really glad you like it!
Seperating what the girls and players eat is definitely in the cards. This could allow for either the girl or the player to eat more than the other.
I'd like to add feeder girls too. They would be behind a toggle when creating a new town (or could perhaps also be added via the custom girl route). As a lot of the dialogue would need to be reworked, I would probably make them distinct feeder personalities.
When on a date with a feeder, my plan would be to turn the mechanics on their head so that the persuasion checks would be for you as the player to resist their feeding (if you so choose). Reaching the overstuffed state might always require such a 'temptation' check as you'd be giving in to the feeder and/or your desires against what your body might be comfortable with.
Hose feeding is still NPC only, but I would definitely like the player to be able to engage in this & the other activities at some point.
Thanks again for taking the time to provide feedback. :)
