There's a secret I can't tell my husband... I just can't forget what happened back then... Middle-aged married women secretly opening themselves to strange cocks... 53-year-old Mari, 25 years into marriage. Tired of her long sexless relationship with her husband, she craves new excitement. For five years, she's been having an affair with a student's father under the guise of being a private tutor. Their relationship is far more intense than it appears from the outside—more fulfilling and deeper than anything she's experienced with her husband. The thrill of embracing each other, careful not to be discovered by his wife, has completely captivated her. For a woman who's lived honestly all her life, being with a man who carries the scent of a 'bad guy' has allowed her to discover a whole new side of herself. But once the affair ends, she's thrown back into a dull, empty routine. Craving that intense stimulation once more, she boldly opens herself to a complete stranger—on camera. A shocking descent as a mature woman's desires spiral out of control.
