Although the couple got married after a shotgun wedding and have not had sex for eight years since giving birth, their relationship is good. However, Reiko, a 34-year-old woman in her prime, is starved for sex. After childcare has settled down and she has recently started working part-time at a supermarket, she has a one-night stand with a man who is leaving the workplace to attend a farewell party for a colleague. Since then, her insatiable sexual desire has led her to come to work without panties or bra, at the command of the one-night stand man, and whenever she gets the chance, she has sex with her colleagues and the manager in the back room as her instincts dictate. She can't stop anymore... "Reiko, I can't hold it in, give me your dick!"
