Aya Masuo played the devoted wife of an aging novelist, living a life of submission. Following her husband's commands, she repeatedly engaged in affairs with younger men—solely as material for his novels and out of obedience to him. Unseen, her husband secretly watched her encounters, growing increasingly aroused by the knowledge that she was being observed. As she willingly spread her legs, lured by pleasures she had never known, her husband became more and more obsessed. But the consequences of this twisted arrangement proved far more shocking than anyone could have imagined.
