Mizuki, a married woman who is dissatisfied with her limited sexual experience and her husband, expresses a desire for something exciting. Without revealing her destination, she heads deep into the mountains, where she encounters unknown men who toy with her body, lick her all over, and do as they please, causing her to become increasingly aroused. Initially shy, she gradually becomes more liberated, sucking multiple penises and indulging in outdoor orgies, repeatedly receiving sperm on her face, and becoming immersed in the pleasure of being defiled.
