Might be an odd question but is the non-NTR content avoidable?
To answer my own question, it's not.
I decided to play, and one thing stood out to me. As a player, I do NOT want to be reminded that I'm playing a game. I do not want my character to say "damn I need to accumulate those stats quickly!" or "I blame you for this, developer of this game!" (to which the developer of the game responds "hey, it's not my fault, it's the player's!"). I also don't want descriptions like "damn, so this is really happening huh? They're fucking your sister! Damn, they're going to split her in half, to get here you MUST have done that on purpose! How crazy is that? Yep, so that just happened!". Own the story you're writing, don't pussy out of immersion for being afraid of sounding silly, that's sillier than writing with feeling.
All that said, pretty solid game. Just make more content optional or easier to avoid. I wanted all characters to be only with the mother's boyfriend but they tend to fuck more people, mainly the older sister with the futa GF and the gang. Would be nice if we could direct them somehow.
