Sounds like some PUA shit lol.

". It is a magnificent read on sexual dynamics over history, and the social consequences of different systems of mating and breeding.
It's not really about nice guys finishing last. It's "nice guys" finishing last. These are the people with low self esteem who are undesirable in every way. They blame the woman for their own failures. They expect romance/sex for being a good "friend."
Yes, they do not understand sexual dynamics and have naive expectations of romantic relationships.
Low self-esteem is probably at the root of most modern social issues.
Attractive qualities are not rocket science to figure out. Be good looking (grooming/style is like 90% of this), confident, don't be an asshole to others, be rich (lol), don't be retarded, be successful in some field, good sense of humor, etc.
Studies have shown that wealth isn't that important. Character trumps money and looks. A man with a purpose and passion is often irresistible.
Anyways why am I talking about this? NTR... right... Classic japanese style NTR is a fantasy and it is meant to be misogynistic. You think real people get raped into liking big cocks? You think the average woman can actually fall so low because of sexual training that she abandons her family and entire life to live as a cocksleeve?
The swinging/cheating/netorase/willing cuck type of stuff of course happens in real life, but the NTR where a woman is stolen due to a superior dick awakening the female instincts... not so much.
Often the
superior dick is attached to the superior man. The stronger man, the more capable man, the more accomplished man, and yes, in those circumstances, there are women who will "trade up". There is a reason why women are so discriminating about who they date and sleep with. Why married women with beautiful kids cheat with their husband's brother, or a co-worker. Women don't conform to men's expectations of their behavior. We've been trying for thousands of years with little success.
Women and men cheat constantly, and always have, ever since we tried to make monogamy the only model. On the surface, people go to church and make like they are chaste but the sex drive will not be denied. Just like when homosexuality has been condemned and made illegal, people were still doing it. Reproduction is the highest priority of most living species.
As far as some women becoming cock-sleeves, I'd recommend you look into the BDSM space. There is no shortage of women (and men) who want to be "owned" by someone else. To be taken care of by someone else to surrender their agency to someone else. It turns them on, and on some level, fulfills them.
