On an AV film set, numerous female staff members such as makeup artists, assistant directors, and managers participate alongside the AV actresses. These women play crucial behind-the-scenes roles and routinely move to separate rooms to wait whenever cameras are rolling. However, within these enclosed spaces, the atmosphere among staff sometimes takes an unexpected turn. Influenced by the sexually charged environment unique to AV sets, they unconsciously become aroused while waiting. In one instance, a bored male staff member and a female staff member end up alone together in a room, leading to an unforeseen, out-of-control encounter. Their secret tryst was captured on camera over the course of four hours.
