Kaoru Sugimura is a 17-year-old virgin who has an S&M fetish. He has always dreamt about an SM relationship with his childhood friend and next-door neighbor Nana Chigusa, who is looked upon as perfect and is always the target of boys' eyes. Their relationship has somewhat deteriorated through the years, due to them hanging out with different people and because Kaoru is not taking his education too seriously. Nana has become very stressed at school, that a teacher suggests she find a way to relax. One day though, Kaoru's mother gives some of his S&M toys to Nana for safekeeping. Nana finds the leather one-piece that Kaoru bought and tries it on but accidentally locks herself in it and does not have the key. After Kaoru frees her of the one-piece, Nana soon discovers that the activity has caused her to relax and improve her academic performance. The two of them start engaging in more S&M activities which they call "breathers." The story follows their activities as they explore the world of S&M while keeping it a secret from some of their schoolmates and family.
The story takes place several months after the end of the main series and follows Nana and Kaoru during their vacation. Kaoru has met his idol, erotic novelist Shuutarou Sarashina, by chance— who, in turn, has been inspired by Kaoru's youthful enthusiasm on the subject of S&M and invites him to help on a new book—while Nana has asked Mitsuko to tutor her on various subjects. Unbeknownst to both Nana and Kaoru, Sarashina and Mitsuko are, in fact, lovers and Mitsuko is the main inspiration for Sarashina's novels, but their feelings for each other seem to have become twisted and broken over the years. Over the course of the vacation, Nana and Kaoru encounter severe depths of S&M that they had never considered before, slowly taking a step forward in their relationship while also helping Sarashina and Mitsuko come to terms with their own feelings for each other that they have hidden with S&M for so long.
