A horny Japanese housewife, dressed in a mini-skirt and fishnet stockings, eagerly awaits her husband's departure on a business trip. As soon as the door closes, she is filled with an uncontrollable desire and she starts to explore her naughty side. She finds herself getting aroused as she starts to fantasise about being taken by another man; her cuckold fantasies coming to life. She then sets out to fulfil her desires, all while her husband remains oblivious to her adultery, deep in his silent business day.
