A middle-aged loser who is single picked up a smartphone dropped by a female college student he passed in an underground passage. While fiddling with the phone at home, he discovered what appeared to be a masturbation video she had sent to her lover or boyfriend. The next day, the man blackmailed the female student, who was looking for her phone, and tortured her with an electric massager and vibrator in a nearby mixed-use building. He filmed her writhing and climaxing lewdly on his phone. The man then took the female student to his home and repeatedly raped her, forcing him to ejaculate inside her!
