Backstory: Kei's step brother spends his summer vacation at home alone with his cousin Kei studying. One day, he manages to take a photo of his classmate and crush, Youko, as a gust of wind lifts her skirt. When Kei finds out about it, she laughs at her brother's juvenile infatuation and starts teasing him about his sexual preferences. From words to deeds, she offers him her own grown-up body—and her brother quickly takes advantage of the opportunity. As summer passes on and the relatives start enjoying more time together, their initially bland tutoring sessions soon turn into a passionate and fiery relationship. They instead spend the time "studying" each other, and trying to reconcile their feelings after having crossed the line.
