This work, which is part of director Shoten Shiro's masterpieces, particularly shines with the presence of Yayoi Mizuki. Her voluptuous body and expressions evoke a sense of nostalgia. Her facial features, along with the moderate plumpness and pure white skin, are a must-see. In the story, the hidden feelings between the step-siblings are torn apart by a bad friend, which adds a refreshing NTR element. The erotic depiction is impeccable, but there are opinions that a bit more visual diversity is desired. Overall, while being overwhelmed by the actress's charm, the visuals could benefit from more creativity. The way the two intertwine amidst kisses and brightness leaves a strong impression on viewers, though the lack of pubic hair is somewhat disappointing. Expectations for future works are growing.
