For me, the greatest appeal of NTR is the corruption aspect. It’s just interesting seeing sweet people completely break down and end up in a state where all they can do is beg for more. I like the idea of the woman, sometimes a strong willed good hearted one, getting it so damn good that she’s willing to go to majorly depraved lengths. For me it’s the idea that the other guy’s dick is just soooo good and the thought of it is so overwhelming that she’s willing to throw everything away to have it. Her marriage, self respect, dignity… All of it is sacrificed for that good dick.
Nothing is tastier than seeing a well mannered girl or even a strong willed girl become submissive once she surrenders to lust. It’s just lovely to see. Most people have the notion that women are these pure and beautiful creatures who do nothing out of the ordinary, but the NTR genre pushes it out of bounds by mixing the powerful emotion of jealousy and depression to create a setting where your typical woman is now a lot hornier and sex crazed than the male protagonist. It’s like an escape in real life because the current social outlook in real life is that men are perverts and are always thinking about sex. In NTR, it’s different. You now have the girl who is hornier and is willing to surrender herself and become someone’s plaything.
There is this old saying: “Men want to sleep with the whore but want to marry the Madonna.” NTR reverses that and makes the Madonna, the Mary Sue, the Yamato Nadeshiko, the prim and proper wife the whore and the mixture of corruption, exhibitionism, and voyeurism spices it up and doesn’t make it as boring as your typical vanilla VN where it’s just a meet n fuck, happily ever after setting.
