After actually watching this work, the setting of a stepbrother who is a lolicon due to the mother's remarriage was intense. The male actor in the first half came off as creepy, while the latter part felt more like an old man than a brother, creating a disconnect with the title, but it occasionally induced laughter. Takasugi Mari stood out with her beautiful face, breasts, and buttocks, and her moans were sensual, delivering the expected excitement in the intimate scenes. Although the storyline was somewhat lacking, her acting shone, especially the gap where the sister initially resists but gradually succumbs to pleasure and eventually seeks it out herself. Scenes highlighting her voluptuous body led to multiple climaxes, making her retirement in April 2020 a real shame. Some viewers hoped for more intense developments, but overall, it's a title worth recommending.
