On her way home from school, Rio Natsuki is scouted and complimented on her cuteness, gradually finding herself in an increasingly strange situation. Before she realizes it, filming has already begun and she's made to sign a contract. By the time she discovers it's actually an adult video shoot, it's too late—using the contract against her, she's forced into performing explicit acts. Eventually, male clients get involved, leading to a grueling shoot where she experiences creampie after creampie, reaching a total of 20 consecutive creampie scenes.
