In a dimly lit dungeon, the cuckold's training begins. His mistress, a stern domme, commands him to service her and her black bull. He's made to worship her feet, lick her pussy, and suck the bull's massive cock. As they fuck brutally in front of him, he's forced to jerk off, his moans echoing in the room. His orgasm is a bitter sweet release, a reminder of his place in their twisted game of power and pleasure.
