NTRD-024 - My twisted fetish: Letting my brother sleep with my wife - Mao Hamasaki

A male teacher marries his former student, Mao. One day, he discovers she had a physical relationship with her own brother during her school days and is shocked. This triggers jealousy toward the brother and a twisted desire: 'I want to watch my wife being taken by her own brother!' Honestly, it's a disappointment. First, the way Mao starts her relationship with her brother is way too casual (like, 'You've never done it? Let's do it then!'), and then she just turns into a nymphomaniac, even doing a 3P with her brother's friend—it's just ridiculous. There's absolutely no sense of the taboo that usually comes with incest themes. The sex scenes where she keeps shouting 'Onii-chan' feel so forced. The premise is twisted enough that it could have been good, but it needed a better director and a more capable male lead. The content is near zero, but I'm giving it one star because I like Mao Hamasaki.
