About the game, I read all the comments and I was enjoying this part of the possible NTR, waiting for updates to clarify this shit.
And to say that there is no NTR or NTR is planned, but to put ourselves as a son of a bitch (literally) is even worse, no matter what happened in the past, future or timeless, I don't want to see anyone touching my mom and that's it. to say that it is not NTR because you are not in a relationship is bullshit, those who do not like NTR do not like to see their LI or future LI being played by other guys.
That said, expecting a very well done exclamation by Dev, to convince us that the MC's mother is a "pure" lady who is waiting for her son to have some action after several years of "chastity". Not a simple one, "nothing happened in the bathroom, much less in the basement".
