Movie description: "My Dad Your Dad 3 Scene 2". Gia becomes incensed when her sister brags that she fucked their new stepfather, Mark. She always thought she was his favorite ever since he kissed her a few years ago. She surprises her stepfather in bed to confront him about his deception. He claims his other stepdaughter was lying, that if he was going to fuck one of his them, it would be Gia. She needs proof of his devotion, proof that can only come in the form of Mark’s cock, which is exactly what she gets. She climbs atop his lap and starts bouncing her impossibly round ass against his dick until it can’t get any harder. She then slips it past her dripping pussy lips. While she initiated the encounter, her stepfather takes control. He shows Gig why she is his most fuckable stepdaughter because she’s built to take every inch of his massive cock. She turns over and bounces her thick ass against him. In doing so she proves how much better she fucks him than his wife. He teaches her how to take cock well.
