Rosie Riches has graduated high school and she couldn't be more proud! She refuses to take off her graduation cap, even wearing it as she goes to make her stepbrother, Nathan Bronson, a sandwich. Rosie brings the sandwich in to Nathan and then lets him know that as his older sister she needs to look out for him for all his needs. She insists that the last time they fooled around she noticed something on Nathan's dick and since his dad had skin cancer, she's worried. Nathan finally agrees and whips it out for Rosie.

As Rosie is peering at Nathan's fuck stick, she realizes that he's getting hard. With a flash of her small boobs, she easily convinces him to let her help him with his needs. Her mouth is hot with the slightest edge thanks to her braces as she sucks Nathan off. Stroking the root as she blows the tip, Rosie gets Nathan way too hot and bothered to want to stop now. Bending over on her hands and knees, she waggles her pert ass in front of him and then hops on top or a stiffie ride on his hardon.

Giving in to his stepsister's needs is as hot as ever for Nathan, who can't keep his hands off Rosie's bottom as she rides him. Turning around on her hands and knees, Rosie invites Nathan to give it to her once again. He delivers the doggy style pussy pounding she's craving. When Rosie rolls over, he goes to town on her greedy snatch. When Nathan is ready to cum, he tries to pull out and Rosie wraps her legs around him to keep him buried inside. She gets the creampie she's been jonesing for, then promises to take care of Nathan and the baby if she gets pregnant.
