Eri, who works at an advertising agency, is a new graduate who has just moved to Tokyo. Due to an accident she caused while at work, she is called to a hotel by some men during her lunch break. Eri negotiates with them in a strong manner, but she accepts a "settlement sex" because she doesn't want her company to find out. Using the footage that was filmed as a pretext, they ask for more sex, and she agrees one after another, becoming the men's sex slave and becoming addicted to pleasure.
