In a stark, white office, a blonde dominatrix professor instructs her male student in the art of chastity. She commands him to remain locked in his chastity device, denying him any pleasure. She strokes his caged cock, bringing him to the brink of orgasm, only to stop and demand he pay her for her teachings. The student, bound by his chastity cage and her financial domination, eagerly complies, licking her shoes and offering her gifts. The professor, satisfied with her student's progress, finally allows him to cum, filling his chastity cage with his load.
