Hikari, a housewife working part-time at a convenience store, falls for a college student named Aoi, who she often works shifts with, and ends up spending a night together. Consumed by the desire for youth, Hikari becomes addicted to the intense sex with his big cock, their bodies perfectly matched. Even during her 15-minute or 30-minute work breaks, she seizes any opportunity to get intimate, falling deeper into a world of non-stop, back-to-back creampies.
