Kurara is a young girl who has a crush on her homeroom teacher, who is always considerate of her shyness. Even though she knows that the teacher has a family, she gives in to her feelings of love and gives her first kiss and sex. On an autumn day, just before graduation, she begs him to take her on a graduation trip just for the two of them. Her first creampie is dedicated to her teacher who has taken care of her.
