Kyouko has a sophisticated aura, the type of woman you wouldn't normally approach. As a career-oriented wife working in the wedding industry, she gives off a high-class impression. Two years into her marriage, she still hasn't had children. Her husband works for a major electronics company and is frequently away on overseas business trips, leaving her home alone most of the time—her sexual frustration steadily building. Emotionally and physically unfulfilled, she seeks illicit encounters, and as punishment for her adulterous mating, she's left with a creampie as evidence inside her.
