Big-titted teacher trained as personal obedient pet

Julia, a female teacher, is at the mercy of a student. Before school starts, she is forced into the gym storage room, dressed in revealing clothing, and lives in fear of being secretly violated during class. His demands are unrelenting: she is forced to masturbate, tied up, her beautiful big breasts are fondled, her breasts are spanked, she is forced to give a blowjob, and she is violently violated. She continues to respond to her student's endless desires with a masochistic expression on her face.
