Alaina Kristar, the seemingly sweet stepdaughter, has a secret yearning for her stepfather's massive cock. One day, as she's bending over in her skimpy outfit, her stepfather can't help but notice her round ass. He slaps it, leaving a red handprint, which only spurs Alaina on. She turns around, her eyes filled with desire, and tells him she wants him to fuck her ass. He obliges, bending her over and ramming his cock deep into her tight hole, stretching it wide. Alaina moans, loving every inch of his big dick pounding her ass, until they both reach a explosive, taboo climax.
