Fresh out of college, Shiori Satonaka arrives for an interview at a package-design company and eagerly presents herself as a serious, dependable applicant. She does not realize the company designs porn packaging. The interviewer pressures her to masturbate so she can understand the actresses whose covers she would create. Then word arrives that the scheduled porn actress has canceled, and Shiori is persuaded to take her place—leading to raw sex and a creampie.
