On its own, yes.
In context and response to the issues with Oliver and Mike you stated, no.
Those issues are completely avoidable.
Laura only has the initial scenes/interactions with both Mike and Oliver, after that, MC can say nope, done. All subsequent interactions, where the issues occur, completely avoidable. The sacrifice is a lot of content/pictures. And we have to collect them all, right?...
I should have been more precise.
I agree, as I stated
, but a very large, arguably largest, portion of the cuckold porn fetish is netorase, because the husband/bf knows and is turned on by it...
Compare the definition of the cuckold fetish and netorase... They are almost identical.
Netorase is even defined as a genre of cuckold or sharing porn.
Where we westerns start to differentiate, because cuckold has a negative connotation, NTS includes sharing, swinging, which unfortunately could also be argued as cuckold porn, but we separate it out, because cuckold is 'bad'.
But let's not get into that and let psychologists debate and figure it out...

So, for the sake of everyone, whether stag or cuck, getting their fap on in peace, I agree NTS isn't always cuckold porn...
TLDR.
Netorase Phone is a damn fine VN/story/game. And while there are things I'd do differently, thanks LeStag for an entertaining product.
