One day, during a search of students' belongings in class, adult toys were found in their bags, and suddenly porn video started playing on the common monitor. Various theories began to emerge about who could have caused this and who was involved in such an outrageous incident. The class president Minami is tasked with organizing a collection of sex toys, but she is hindered by her classmate Anri, who has long shown interest in her. As a result, Minami faints from exhaustion.

The next day, when she asked several boys about their strange behavior, it turned out that they all had a porn video in which Minami masturbates with the sex toy confiscated the day before. In the video, Manami smiles seductively and says: «P-please tell me tomorrow how many times you came in me, and show me this video...» Manami is shocked and denies any involvement in what happened and claims she has nothing to do with this video.

Anri starts deleting videos from the boys' phones. One of them runs away, but he is swallowed by darkness. Panic begins in the class, porn video appears on the monitor screen again, and the teacher Hinano recalls a similar incident from her school life. She believes that the class is cursed and that they must have sex every day to break it. Those who try to run away will be swallowed by darkness. The boys seem to have realized their luck and are now enjoying the situation...
