Sato Nana, a new employee who started working in the editing department this year. On Tuesdays, the editing room is always just the two of them. Her boss, a deeply twisted masochist, secretly fantasizes every day about becoming her servant. His secret is uncovered by amateur sadist Hayama Kumiko, who met Nana by chance on the street and spent three months investigating. On a Tuesday, after confirming the boss is away, Kumiko reveals everything to the innocent Nana, and the two team up to strip him completely naked and fully dominate him like livestock. One humiliating torment after another follows—tying his penis with rope and dragging him around—creating an unforgettable spectacle. From that day on, the office on Tuesdays becomes a servant-breeding room, and Nana relentlessly trains her boss to be her licking dog. Her cute, anime-like voice spewing cruel verbal abuse creates a shocking, dreamlike scenario that fulfills every masochist's fantasy.
