Living in Tokyo as a ronin student, I’ve just moved out of the countryside and started living alone with my aunt. But she’s intensely curious about men—and soon sets her sights on me, still a virgin. Every day becomes increasingly unbearable: she forces me to drink milk mouth-to-mouth, makes me perform mutual masturbation, and subjects me to relentless sexual advances. Will my chastity survive? Before I even face university entrance exams, will I lose my dignity as a human being? This is an erotic coming-of-age story depicting my inner turmoil and the shocking developments in my relationship with my aunt.
