Ass licking performance tends to improve when a whip is used as incentive. In this case, Mistress Antonia whips while the slave while he licks Sophies asshole. "Faster, lick my asshole!" Sophie demands, the slave barely able to hear her commands over the crack of the whip. "Faster, harder!" Sophie yells, demanding perfect performance. The slaves moans of discomfort increase as Mistress Antonia doesn't let up with the whip, but Sophie doesn't care. She wants his face in her ass and his tongue in her asshole. And he'd better perform!
