Sai works at ● School as a 27-year-old math teacher. One day, she is summoned to a hotel by a male student and shown a stolen photo of herself entering a love hotel with the vice-principal. "If you do what I say, I won't tell anyone," he proposes. Feeling danger from the student who pulls out a camera, Sai tries to gently refuse, but she is forcefully and roughly caressed. Despite feeling disgusted, she can't help but let out a voice at the pleasure of being filmed. Her precise technique, honed after leaving ● School, makes her twitch and drench in love juices. ... The sequel to the series appears after more than 10 years.
