Since it's a slow corruption game, he's developing a mid stories to shift from part 2 to part 3 ..you can consider it as ending of part 2 and preparing ana for sex with slow corruption.
There are many non NTR games, non cheating games...maybe this game is not a genre for you if you prefer to play non cheating games.
Offcourse there will be non cheating path in this one too. But I will be honest if any developer has efficiency to produce like 400 renders per quarter and he invest his time to develop non cheating path in every update where the game is all about cheating....it means he'll have to compromise on cheating paths, and make those path less seductive or less animation ....or if he takes his time to develop everything...it will take an extra month for an update release. So we will see how it goes.
