Natalie climbs onto the bed and asks if this is what Tony's been after as she takes his dick in hand. She helps him stroke it, then climbs on top so that her wet twat accidentally slides down on Tony's man meat. Her stiffie ride gets hotter still as she turns around and goes to town bouncing that booty on Tony's dick. Tony can't help but spank that ass. He can't stand it another moment; he gets his step sis on her belly and pounds away at her ultra-tight twat. to her back, Natalie is all smiles as she continues to take her brother's fuck stick between her thighs. The horny teen is locked and loaded to cum at the naughtiness of the situation. She's not about to leave Tony hangging, though. Instead, she gets back on her belly and goes back to sucking his hardon until he fills her mouth with a hot shot of cum.
