Tanaka Setsuko, who lives with her son, has a secret job that must not be known to others. It is prostitution disguised as a caregiver. She secretly distributes flyers around town and responds quickly when contacted. Setsuko's clientele is mainly people with physical disabilities, but occasionally able-bodied men also contact her. On such occasions, the men she is with are usually exceptionally horny, so Setsuko forgets about her work and enjoys herself... Two other stories are also included.
