I think there are some great opportunities to include some more fetishes. I'd love to have the opportunity to wear (and have others wear) swimwear, both one piece and two piece. This could just be added to the sports store.
Also, I kind of expected some ABDL content after seeing the comment one of the people in the nursery makes about ridiculous diapers. Maybe there could be a hidden entrance there leading into an area where these kinds of fantasies are fulfilled. There could also be a shop there that sells diapers and AB clothes and accessories for Lust Doll to wear and use.
Since there is already the option to eat and drink, and also there are toilets available that are currently only used to masturbate, how about extending these so Lust Doll actually grows hungry/thirsty, along with negative imacts of these conditions. And of course afterwards a need to use the toilet (or maybe a bush/street corner for those that may be into that, along with possible negative response from Arlene, and of course use a diaper if that content is activated).
Man, this game makes me follow thoughts and actually enjoying stuff I never before considered. So on this point alone the game is a great success!
