The highly popular S1 naked series returns with its third installment! This time, a private tutor arranged by my father arrives at our home. To my surprise, the tutor is a woman—and she practices a fully nude teaching method. The moment she arrives, she strips naked right at the entrance and walks straight to my room completely bare. Her name is Ayumi Kimito, a stunningly beautiful teacher who maintains an elegant smile even in the buff. Drawn in by her charm, both my father and I gradually become obsessed with this naked tutoring. The story captures the two of us completely captivated by her otherworldly presence, as if a fantasy being had stepped into our everyday lives.
