Tony is in the bathroom getting ready for work when his stepsister Natalie Knight barges in and insists she needs to get ready for school. Before Tony can react, Natalie is pointing at his dick and giggling at his morning wood. Tony tries to defend himself, but Natalie is relentless. Later, after work and school, Natalie comes into Tony's room to apologize. She also shares that none of her previous boyfriends have ever been big enough to please her because she's obsessed with big cocks. She asks Tony to show her his dick. Tony tries to turn down his size queen stepsis, but Natalie isn't about to take no for an answer.

Peeling off her shirt and climbing into bed, Natalie climbs into bed and puts her bother's hand on her plump titty. Tony can see that Natalie isn't kidding around, so he slowly relaxes as his little stepsis seduces him. Popping Tony's dick out of his pants, Natalie smiles big as she finally gets to see that giant D. She sucks it, strokes it, loves on it with her mouth. There's just one thing missing from this fantasy come true: Having that big cock make her cum. Fortunately, Natalie has big brother Tony to help her make that happen.

On her knees, Natalie moans in excitement as Tony squeezes her ass and slides on home. He gives it to her hard, just like Natalie is craving. When Natalie flips over, Tony gets to admire his sister's hairy pussy as he bangs her. Splaying herself out, Natalie opens herself up for Tony to have his way with her. He gives her all the big dick energy she can handle, pounding that pussy and then laying on his back so that Natlie can enjoy a stiffie ride. Now that she has gotten her rocks off, Natalie rewards Tony with another blowjob that won't stop until she has a mouthful of hot cum.
