Kate, a bi vixen locked in chastity, is led into a dimly lit room, her eyes meeting the cruel gaze of her Mistress and the eager, erect cock of another woman. With her hands bound behind her back and a gag in her mouth, Kate is made to kneel, her face inches from the throbbing flesh. Her Mistress, a sadistic English beauty, commands, "You will suck dick for me, Kate. Prove your worth as my bi slut."
