A dull teacher relieves his stress by using a sugar daddy app. One day, he meets a girl by chance who turns out to be his former student! When he meets her again after a long time, she has grown into a sadist who holds his weakness and bullies him, saying, "If you don't want me to tell anyone, then listen to what I have to say." He begins to feel pleasure from being forced to ejaculate every day, and is at the mercy of the nasty slut's techniques!
