The stepfather's patience wears thin with his insatiable stepdaughter's constant demands for attention. One evening, he decides to give her a lesson she won't forget. He grabs her by the hair, pulling her to her knees, and shoves his cock deep into her throat. She gags, chokes, but he holds her there, his hips thrusting, teaching her the art of deepthroating. Her eyes water, makeup smudges, but she learns quickly, taking his cock like a good girl, until he explodes down her throat, marking her as his.
