The Fallen Wife: Chastity Violated(2000)

Yōko and her husband, Teruhisa, run a café—yet lately his attentions have drifted to a young school girl named Haruko, leaving Yōko feeling abandoned. Beneath her composed exterior, a simmering lust has been growing: memories of Teruhisa as the passionate first lover she once knew, and a secret craving for something more depraved. Haunted by Yōko disappearance, Teruhisa retraces their past, until his search leads him into Shinjuku—to a “peep room.” There, through a peephole, he catches sight of his wife swaying in nothing but her slutty lingerie, every move an erotic confession of the desire she’s kept hidden. Yōko surrenders to the pulsing rhythm of hidden lust. Each sway of her hips is an invitation—slipping into the abyss of pleasure. Teruhisa realizes there was once something she tried to say on the night they first made love. Now, driven by a mixture of longing and guilt, he must hear the truth of her yearning before she plunges irrevocably into the depths of her darkest desire.
