I thought about the Life-O-suction/weight reset idea 💡, you already have feede's personas in the game. Maybe if possible you could give the women who get Life-O-suction gain the Veteran Feede trait bonus to said lady's so they gain the Feedes personas ability to eat without fuss with a tag by their name to note they are a Veteran Feede. You maybe could add bonus dialogue to the non-feede personas once they gain veteransy.
I think their should be a option to just reset their weight for does who would like just have their girls lose the weight & be vanilla. But if a player goes down this route, the lady would think that the player wants them to be back to normal so if the player trys to fatten them up again they will be far more resistant to the idea 💡. They could have quotes about about feel kind of betrayed as they go up weight classes with them becoming more resistant with each weight class up!
One path is speed running gains for fun & the second path is a semi hard mode for those who dare.
Sorry 😅 if this is a lot, I'm a thinker at heart.
