With all due respect, I don't think you understand the distinction between netorare and netorase. Netorare *is* cuckolding, which can include flat out cheating where the MC is completely unaware, but the focus is the MC being forced to watch in most cases against his will which somehow gets him off (also against his will). All of the dialogue regarding MC realizing he's a cuck is hesitant and uncertain, he's not 100% okay with it yet but he's resigned to the fact that Lara will do what she wants with or without his approval.
At the beginning of Chapter 5, on the NTR path, the MC is asked if he likes it, and there is little hesitation or reluctance when he says "yeah, I like watching you fuck other men." At least I didn't gather the hesitance on the behalf of the MC. You may have intended differently, but that's what it was to me. And it's very blatantly against Netorare as a whole from perspective, possibly due to differing ideas of what NTR is.
There are times, specifically with the pizza boy, that is straight up cheating with the MC unaware, or cases in which he's suspicious or is shown a picture hinting towards it, but it's massively overshadowed by, as Joshy92 said, with that form of western NTR. Going into this game, and having played every chapter until I stopped at Chapter 5, I felt it was an okay balance, but clearly this is going in a direction that the supposed cheating is being replaced or consistently overshadowed by a theme of voyeurism/sharing, which dampens the NTR for me massively, and is practically Netorase in everything but the "reluctance".
So, with all due respect, I think my statements are absolutely logical, it is simply a matter of your definition of NTR goes closer towards Voyeurism and Sharing, and thereby closer to Netorase, rather than my traditional view of NTR as hard cheating, MC being unaware or only getting hints of it, with jealousy a significant emotion that can be felt that I simply didn't feel in this. Perhaps the dialogue is different in your Netorase path, I don't really care, nor consider that a factor in what I feel, because the themes and emotions are practically identical to Netorase from my point of view. Others may feel different, but that's my stance. Do with it, if anything, what you will.
