A submissive male, eager to please his Mistress, is guided through a humiliating yet arousing cum-eating session. With a dominant female voiceover, he's ordered to stroke his cock until he's ready to explode. As he reluctantly complies, the Mistress's voice grows more intense, "You will learn to love eating your cum, slave. It's your purpose." He tentatively tastes his own essence, grimacing, but with each instruction, his resolve crumbles, and he's soon devouring his own seed, craving more.
