In a dimly lit, kinky dungeon, a power-hungry mistress indulges in her bi-femdom fantasies. She's dressed in black latex, a strap-on cock hanging heavily between her legs. Her male slave, bound and gagged, watches eagerly as she trains a new bisexual recruit. She makes him strip, exposing his vulnerable body, then orders him to service her strapon. He's hesitant but excited, his hard cock betraying his nervousness. She teases him, slapping his cheek with her strap-on, before making him suck it, pushing it deep into his throat. She humiliates him, degrading him in front of her male slave, but he's loving every minute of it.
