Koharu is a short-haired high school girl who is kind, caring, and lives up to her title as an honor student. She is a popular girl who is known for her weak-willedness and carelessness. When a boy begs her to have sex in public, she says, "...yeah...it's fine," and gets five guys' semen splashed all over her face in her first mini-bukkake experience! Even if she's weak-willed, isn't it too much for them to do whatever they want to her?
