Nurses who are taking a break or out on the town are approached and asked to come to the studio. In a challenge project, they are told, "If you can make an AV actor ejaculate, you will receive 100,000 yen per shot." The nurses are confident and eager to participate. Every time they make an actor ejaculate, they get excited and a sense of solidarity is born, and they start having sex! And the last way to make him ejaculate is to cum inside him!
