Yuta??s dad remarried, and now Yuta suddenly has a stepsister around his age: Remu. Yuta??s current girlfriend becomes furious because Remu is incredibly attractive, which causes trouble for Yuta. Yuta is a bit annoyed by the situation, especially because Remu is extremely silent and quiet. He starts teasing her and discovers that she does everything he orders. As a result, his requests gradually become more sexual. ?? This movie has a lot of firepower, and Remu got seeded nicely. Can??t help to feel that her acting was very limited by the role, but that is a key part of the story. Overall, it??s good stuff.
