Main game. Story spoilers:Is Futa just in the one What if or in the main game too?
Don't know if you played the game before or not, so I'm just going to assume not. The main antagonist is the MC's grandfather, Hunter. He has a son, Uncle Drew, that no one has seen in years, or at all for some characters. At some point the MC learns that Drew had basically been trained in the ways of seduction/corruption by Hunter. And now Drew is coming for a visit, oh no, new antagonist!
Then when Drew finally shows up it turns out that he transitioned at some point and is now Aunt Drew. She still basically functions as a new, but nicer, Hunter (and certainly prettier than Hunter who looks like he spent so much time in the sun that his skin cancer turned sentient and took over the body). Meaning there are non-canon bad ends where the MC fails and Drew steals the girls. Also it's not really clear if Drew is actually nice or just faking, and whether or not she'll get any sort of redemption at some point.
