In a kinky twist on traditional education, a bisexual femdom instructor uses her strap-on to teach a curious student the joys and humiliations of being a cocksucker. The student, eager to learn, is quickly overwhelmed by the instructor's size and dominance. She teases him, slapping her wet pussy against his face before forcing his mouth onto her strapon, fucking his throat roughly. The student, now her 'bi-cumslut,' is left gasping and humiliated, but eager for more lessons.
