An email arrived at the production department from a certain man. "I am training my student, Yuri, as a sex slave. This spring, Yuri will be graduating, so as a commemoration, could you please film her lewd and masochistic side?" Yuri is trained in front of the camera. Punishment spanking. Full body trampling, and anal licking service. Her glamorous body is toyed with despite her innocent face. Yuri has completely become her teacher's sex slave.
