There are more instances of submissiveness on a later playthrough but most of them consist on getting fucked, watching somebody get fucked or being an object of service, the game is thought on having a normal straight woman allow your submissive deviancies since it would make more sense to just be the dominant one. It is though, a game of "Not being an asshole" = Submissive.
I will rewrite and add more softcore both dominant or submissive on earlier gameplays, I was not planing to add "cute submissive" but after this comment, I probably would.
