I liked this interaction because there wasnt any personal attacks or name calling. Its rare.
I guess Im more of a modified vanilla guy, I like harem stuff but NOT a fan of SA, humiliation or blackmail, which I rarely see outside of NTR or corruption games which usually the venn diagram for NTR, corruption and the other 3 is a circle. I understand everybody has their thing. I won't ever understand the desire for someone to see another man with their SO, thats a blind spot for me I guess. I usually base my game/ VN choices on the art/ models( duh) and then the story,( incest is also a no go unless I can change the relationships in game, which is also a huge portion of stuff here) its been very odd to see the rise of these NTR/ corruption games especially considering that the art used ( AI or otherwise) is usually quite good. just my opinion. have a great day.
Every fetish has point of inception.
Likely causes for cuckolding is inability to fight someone.
Harem is not vanilla per se but it is in but is very close due to male biology.
I've studied some fetishes and especially NTR (due to being heavily invested in Japanese culture for many years and i saw a massive rise of NTR compared to 15-20 years.
For example japanese cucking is more cultural. They cannot oppose higher ups. (Bosses, police, politicians and etc.)
"Western" is more physical and less mental. More leaning towards racial thing. Mostly in my subjective understanding coming from USA.
Thus cuckolding is actually like your organisms coping mechanism to alleviate pain you experience while seeing this. (Because being cheated on is psychologically proven and backed up by papers to cause immense pain. It is obvious who experienced it but well everyone needs empirical data now).
So there are "natural" way how people become cucks i.e. by random events in their life that ignited it and there are institutional (like Japanese culture having indirect effect which increases amount of cucks from the norm base value).
For example my early age(like really early) experience with older woman made me a milf fetishist, until i became old enough to become a dilf.....It wasn't traumatic but girls of the same age seemed bratty and lacking for many years to come due to that experience, even their bodies seemed like they aren't real women.
So some cuckolding fetish might have been caused when as a child you experience some form of male to female attraction towards a family member(childhood friend) and you see them having sex(or hear an explicit story which ignites fantasy), you might feel a tingle of betrayal and pain which later on makes you a NTR connoisseur.
As for this game? Like you stated NTR is not your cup of tea and then you stated incest is also not to your taste. Imagine finding a magical unicorn who has both of those fetishes.
Even if you aren't an incest or ntr fan seeing your family members get fucked by strangers is another horror story. Many children do not want to see their parents fucking each other less so to be it with strangers or with family friends or acquaintances.
So the whole recent flaming here is somehow justified. This game is mainly portrayed as incest fetish. If you immerse in this story even if you don't like incest seeing "your" mother providing sexual services to anyone is already asking for a riot.
If it wasn't incest game, once again seeing "your" acting like a hoe would likely cause bad feelings to erupt.
BUT, it is still not known what MC mother does on her nightly visits.
In the future maybe people will be more accepting of this (BUT majority still will not like it) due to rise of divorces, break ups and onlyfans.
