This is a record of the erotic work that Hasegawa Otoi, a female college student who has been offered a job as an adult video director, experienced during her internship training. Hasegawa is an honest, straightforward, and competitive person, and although she is hesitant, she tries anything her seniors tell her to do. The sexual training reveals a perverted side that she herself has not yet realized, and even before joining the company, she orgasms multiple times and wets herself in the office as she goes about her work.
