Of course there was no need (is there a need for anything in these games?), he wanted to.
If one looks for a game with NTR, this game is not to his liking. He would not even know the mentioned scene if he read the tags and didn't play it in the first place.
Tbh I am really fed up with what players expect and what not, what goes on in their minds. It's all about whining and complaining that the dev didn't exactly do what they expected.
Let the dev tell the story how he likes. If it involves showing other guys, so be it. If not, then not. One can always hammer the space key to fast forward the scenes he doesn't like.
