A trembling man kneels before his mistress, her eyes burning with kinky intent. She grabs his balls roughly, squeezing and pulling, making him gasp in pain and pleasure. She forces his head down, commanding him to lick her balls, his tongue tentatively exploring the sensitive skin. She growls in approval, pushing him further, making him take her balls into his mouth, sucking and licking as she demands, her dominant voice echoing in the room. She revels in his submission, her body writhing with pleasure as he services her in the most taboo of ways.
