Good luck to you dev, but that seems like an impossible task. I hope it works out since I'm always on the lookout for more FMC games. The chief difficulty it's hard to write a consistent character that can do all the fetishes (i.e. their behavior being caring vs abusive, shy vs confident, etc), granted you can always handwave it as being bedroom roleplay to try get around the inconsistency.
I won't get my hopes up for a cuckqueaning (reverse NTR, being a harem member) alpha of a romance interest that doesn't pimp or share the player since there's practically no games that do that with a female protagonist, but hopefully that means there will at least be options other than the usual take every dick slutification/prostitution route or incest bunny.
