Riho had heard rumors that her husband was being subjected to persistent workplace harassment, but she was shocked to discover the culprit was none other than the president's son. Under pressure from her husband, who feared losing his job, Riho is summoned to the mansion and forced to serve as the son's personal maid for three days. Initially reluctant, she is made to perform increasingly extreme tasks—bodily cleaning, assisting with masturbation, and wearing a maid outfit. Eventually, she is coerced into receiving repeated creampie after creampie. Though she resists at first, Riho gradually succumbs to the man's insatiable stamina, losing herself in pleasure until she willingly accepts unlimited creampie after creampie. Those three days become an intoxicating dream of pure ecstasy.
