Megumi Kurata is a full-time housewife living in Urayasu City, Chiba Prefecture. She used to work for a pharmaceutical company, and married an older doctor working at a university hospital six years ago. She still lives a stable life with nothing to worry about, but there is one thing she cannot stand: sexual frustration. This is the first infidelity of this extremely lewd and slightly naive wife who wets her panties and runs off in search of the extraordinary and sexual pleasure.
