Sisterly Lust contains hours of content and many branching paths. The main cast is supported by a large ensemble of (female) side characters, each with their own story to tell. Will you romance Bella, or develop a different relationship with her? Do you want to discover what secret Susan is hiding? Rachel is clearly an open-minded girl, but is she daring enough to allow you into her life? Liza's boyfriend is a verified douchebag, but do you care enough for her to oust him from her life entirely?
The game is built on choices that will have an impact on the gameplay. Each main character has two statistics; Trust and Corruption. Scenes will unfold based on those two parameters. Be careful not to lose the trust of any of your siblings, otherwise your stay at your new home will be a very short one.
All main characters (including the protagonist) can be named.
