Saori leaves her husband behind after being assigned to a major business negotiation. She was chosen because the client company's arrogant, womanizing president Oki is expected to favor the prettiest woman in her office. After her senior Sato is quickly plied with alcohol, Oki uses the contract to coerce Saori into sex under the guise of client entertainment, humiliating her, forcing repeated orgasms, and creampieing her again and again.
