Newlywed office worker Karen, who is trying to conceive with her husband, is ordered to accompany her boss Tabuchi on a business trip. She reluctantly goes, only to discover that he has arranged a shared room with no escape. Determined to protect her marriage, she resists until an aphrodisiac leaves her helplessly aroused. Her boss immediately creampies her, forces her through a humiliating foamy body wash, and drives her into unwanted orgasms. By sunrise, repeated creampies and degrading sexual training have conquered her with pleasure, leaving her tightly servicing the boss she once despised.
