The housewife, Mami, lives with her son while her husband is on a solitary overseas assignment. Mami's son's friend secretly harbored feelings for her. On the day he came over to stay and work on a report, he fell ill and was left alone with Mami, who was then seduced and eventually gave in to his advances. Although she was supposed to have been violated, her body reacted to the long-forgotten pleasure, and she became intoxicated with ecstasy. Soon, the friends' desires spiraled out of control, and Mami found herself being fondled even in her son's presence, gradually sinking into affairs with them.
