Can i make the story solely yuri and futa on female without male, the hunger system makes me hassle
It is not really intended for players to be able to avoid straight content, but this planned to be a valid way to play my other game, Hex (“yuri mode” is coming in an update to that game this week).
For SS, the best you can do is (1) start with lacticals, (2) grind TP and alchemy, and (3) buy the trait that enhances feeding off of breast milk as soon as possible. Even then, this doesn’t completely remove all the straight content and references to it, but it should make it so you can largely avoid straight sex as part of the sandbox gameplay.
