This work combines the theme of remarriage with children and erotic suspense, showcasing the director's talent. The peek-a-boo scenes during cleaning, where Uehara Natsumi's body lines shine through revealing outfits, are exceptional. The bathing scene highlights her beautiful physique, and her erotic nipples are irresistibly charming. Although the sagging of her large breasts is barely acceptable, it adds a natural appeal. The acting has some shortcomings, but Natsumi is at her cutest here, with a unique rhythm in her periodic long-inhale moans that becomes addictive. The story builds suspense until the mid-point, but those expecting the classic 'violated by the stepchild' plot might be slightly disappointed. Overall, it's a work focused on costume and body presentation, making it a treat for fans, with a comprehensive score of 4 points.
