The Chaste Professor (Femdom, Chastity)

Stephen is a sexually inexperienced university professor who is seduced by Jane, one of his students. She manipulates him using compromising evidence to get her own way, forcing him to write her essays and locking him in a chastity cage, gaining more evidence of his kink and luring him deeper into her trap. Will he ever be free from her grasp or will he have to face the ultimate humiliation?
