The developer has quite the list of fetishes that they want to fulfill, if the itch.io site has anything to say about it. Given the slow and cutesy start, they're going to have to be careful in their pacing to actually make it all happen properly.
It is also very early to really tell 100%, but there are some hints as to which girl will deal with what.
The exhibitionist stuff is lightly found everywhere right now, but is very likely to be handled mainly by the white haired kuudere since she sees no issues with getting naked at the drop of a hat. Also possibly the femdom to some degree, as she very quickly asserts herself as the older sister to the femboy.
The aunt character seems to be the likely culprit for feminization and crossdressing, considering she's already hinted at how much of a shame it is that he wants to do away with his feminine looks and clothes (Maybe already looking to make a new daughter?). Not to mention the obvious pegging and futa x male, given her early reveal of equipment... But we don't yet know for sure which other female character is also packing. Possible all of her daughters, given the game title, but who knows yet.
Class rep older sister gal is likely the subject of NTR and corruption, given the teacher shadow dude and how repressed she is. Hard to judge anything else though, beyond some random hints that could go anywhere: She's has trouble making friends, has something hidden in a false book (possibly a toy?), and is apparently very physically strong, yet is also always super tired every evening.
The sporty gal is the one I'm having the greatest trouble placing. Her scene had a bit of exhibitionism, and she's the most lightly dressed, but she's otherwise just a very forward tomboy. Super cute though.
