Spent an hour or two playing around with what you've released so far - it is pretty simple so far, but fun!
This sort of 'gender domination' theme where males are put into a humiliating, submissive social role beneath futas and women is really hot, and I always enjoy seeing that sort of thing. If you want my vote - more worldbuilding and such in that direction would be fun!
I really liked Naomi - it's sad she didn't keep me as her submissive boyfriend when I knelt to her, though. (Though maybe there is a scene/ending where you accept her domination that I haven't found yet) Though that might be a bit softer than what you have in mind for this story!
