Sumire, the wife of Mihara Corporation's president, grew tired of her husband who neglected their home and sought solace from her son. After that, mother and son crossed the line and became lovers. Today, they finally embarked on a long-awaited hot spring trip together. The two arrived at their destination inn hand in hand, but a man gave them suspicious glances. This man had been burned by Sumire's husband's company during a transaction and held a grudge against him. Unaware of this, Sumire and her son immediately headed to the private outdoor bath. After soaking for a while, her son began to desire Sumire. She responded in kind, and they made love throughout their reserved time, leaving the bath satisfied, unaware that the man had been secretly filming them. In the evening, as Sumire walked down the hallway, the man called out to her. Suspicious, Sumire was shown the video from earlier. Shocked, she was pulled into an unpopulated area and forcibly kissed and groped. Her body, sensitized by her acts with her son, responded even to rough caresses, and she was forced to climax. The man exposed his penis and made Sumire take it in her mouth, ejaculating inside. Sumire was left speechless when the man said he would enjoy himself with her for as long as they were at the inn. When Sumire was summoned by the man, she went to his room where his subordinates were waiting. She offered her body as instructed, being teased and brought to climax with words, fingers, tongue, and penis. The pleasure she experienced was unlike anything she had ever felt before, and even after reaching orgasm, her body continued to tremble. That night, Sumire complied with her son's demands for sex, but his inadequate performance left her unsatisfied. Unable to find relief by touching herself, Sumire found herself sneaking into the room where the men were sleeping in the dead of night…
