i prefer the way JAV handles "cuckolding" or netorare, rather than the way it's done in the U.S. in JAV it's hot, whereas in the U.S. it's a genre for losers and suicidal wimps.
in JAV, it's mostly the hotwife, girlfriend or daughter cheating or being initially taken advantage of (then showing her voracious appetite & skills) in front of the husband or guy. sometimes the guy is restrained and made to watch. or sometimes the guy is out of the room entirely.
in the U.S. it might as well be called gay porn because the cuckold is typically a wannabe c0cksucker, asslicker or worse. not really an unsuspecting cuck but a male nothing, into humiliation and really a twink, bi or gay fatso. that's how the dogsh!t, excuse me, dogfart scumbag studio usually handles it, esp in interracial scenes.
basically in the U.S., cuck porn is used to perpetuate racial stereotypes. in other words, it's not eroticism but racism and anti-white-male-heterosexuality.
in JAV, netorare is generally focused on the extremely hot young (or MILF or jukujo) woman and even though the guy might be "victimized" in some way, it's generally not an attack on his sexual potency or worth as a human being.
