She wants to be held as a woman, not as a wife or a mother... In the steam of the hot spring, she indulges in a once-in-a-lifetime secret encounter with the man she meets. That's how to enjoy a "Hot Spring for Married Women."Sumika Kondo is embarrassed by the man's gaze, but the moment she sees his erection, Hitomi moisten and her cheeks flush... On the morning of an adulterous getaway, Miwako Yamamoto, who has a masochistic nature, writhes in agony as her lover tells her to do embarrassing poses in the bathtub... Then a stranger appears... Shinobu Oshima indulges in masturbation in the guest room at night, takes a sip of wine and heads to the bath to provoke a male servant who has just finished work... The coquettish voices of five married women echo throughout the hot springs.
