In an abnormal situation where she's taken on a trip by a man she's meeting for the first time—arranged by her own husband—married woman Rika (25) is filled with anxiety and tension. At the inn, as the man begins to caress her, her body reacts lewdly despite her lingering hesitation. But once his cock penetrates her, she trembles with uncontrollable pleasure, moaning obscenely. When he stops, she begs him on the spot to continue, craving more. By evening, drinking her favorite alcohol, she gradually becomes more uninhibited as the alcohol takes effect. Her attitude shifts from resistance to acceptance, and she starts actively pursuing pleasure, seducing the man with vulgar words. Captured here is the transformation of a married woman, blushing yet surrendering wholeheartedly to ecstasy, as she falls deeply into depravity.
