Your ideas would work in a world where peace was an option, lol.
Deepones: these fishes enjoy doing this, a female doesn't have the privilege to do such thing, she is another sow who needs her hole expanded.
Goblins: same thing, except goblins are even more keen to not let females have their fun, as Scared and Despairful females is a fetish to goblins.
Abomination: Check their ending, they don't need a female to defend them, they just need to breed females as fast as humanly possible before their female sows decay. (Edit: the brain parasite thing didn't make sense tbh)
Woodson: mmmmaybe? They sustained them selves enough, they also have farming skills, but they have horrible parenting/housecare skills, just look at their son.
Snowflake: he is too mentally unstable and doesn't know how to spend money well, i don't see a universe where he can be a good husband, Did you check his basement?
Bobo: he already has his good ending, but yea maybe we need more "kind" bandits huh? xD
Church: sounds pretty good ngl.
keep in mind that the economy and survivability of Noer island is crumbling, there is no place for a Street Rat like Lona to be desired, the game design is made to be torturous and you have to escape it all, No comfort.
With all that said, i like your ideas lmao.
Not expecting anyone to treat Lona well (except BoBo) these were more like ideas of what they could do but I can think of some reasons they'd give Lona "privileges"
Deepones- Lona could be "helping" other slaves readjust to their new lives by stretching their holes, convincing others not to try and escape, force feeding women that have given up wanting to die
This would reflect the give up ending where it shows Lona help a new girl readjust
Goblins- I could see them pointing, laughing and jerking it to Lona beating other slaves, forcing the other women to drink her pee, dragging women back trying to escape, force feeding someone their friend so they don't die of starvation. Put simply Lona abusing other women is fap material
This would reflect the Goblin ending where they laugh and show Lona her own reflection revealing that she became a monster but now it would also reflect her turning into a monster mentally
Abomination- Yeah no real reason unless it was a hidden perk for Abomination Lona or something another alternative is Elsie doing Abomination breeding experiments on Lona though that would be a different scenario
Woodson- Still treat her shitty she just doesn't have chains and get fed a little better so Lona can live long enough to raise a kid with her "husband"
Really not necessary to have a scenario for each slavery event (at that point it would just be a ton of work better put towards a second game or paid DLC) it would just be nice to have another way to farm for kids since camping out at the inn and/or Elsies clinic can get repetitive
And to reiterate Lona should not be treated well by any means (except by BoBo) it would just go from near impossible to survive long term to maybe you can survive long enough to try for a couple kids
Also the idea of the Lesbian content people have been asking for turns into Lona gaping and pissing on slaves is oddly funny to me
