I think the thing to discuss here is, are "NTR" and "Cuckolding" the same thing? Or are they different things? I think they are different. Because "Netorare" is a combination of two words, one of which means "stealing". As far as I know, there is no "stealing" in cuckolding. Moreover, there is mutual consent. That's why I think this game is not NTR but cuckolding. In this game, Eric does not steal, Max allows Eric. They make an agreement as if they were "shopping" on some issues. Max is not happy about this, but there is no stealing either. Actually, this game is stuck somewhere in between. It is not NTR, it is not cuckolding (of course, I am saying this assuming that they are two different things).
