学校のカースト上位にいる美形ギャルの七ツ森。担任教師である僕の言うことなんか何も聞いてくれない。授業も途中でエスケープして、注意したら「長くなるならLINEください」と言われる始末。そんなある日、僕が病気にかかって学校を休んでいるとひょこっとお見舞いに来てくれた。「どうせ先生もてないし彼女とかいないだろうなと思って。感謝してよネ！」本当は心の優しい七ツ森。一生懸命に介護してくれて、チンポにも優しくって、手コキにフェラ、SEXまでしてくれる七ツ森。もしかして、僕のチンポに惚れてる？

Nanatsumori is a beautiful, popular girl at the top of the school's social hierarchy. She doesn't listen to anything I, her homeroom teacher, say. She even skips class in the middle, and when I try to scold her, she says, "If it's going to take a while, just text me." Then one day, when I was sick and absent from school, she suddenly came to visit me. "I figured you're not popular and probably don't have a girlfriend. Be grateful!" Nanatsumori is actually a kind-hearted girl. She took such good care of me, was gentle with my dick, gave me a handjob, a blowjob, and even had sex with me. Could it be that she's fallen in love with my dick?
