When Codey notices, he can't stop staring. That causes Harley to realize what has happened and to go on the attack that Codey shouldn't be looking at her like that! Even worse, she can see that he's starting to get hard. Obviously that means Codey has been perving on her. When Harley points out that Codey has been having inappropriate thoughts about her, he denies it. In a "prove it" moment, Harley tells him to whip it out and demonstrate that he's not hard or else she'll tell her mom that he was being inappropriate. Of course, Codey can't let that happen. He does as Harley insists, then watches in disbelief as his stepsister wraps her hand around his fuck stick and pulls it close so she can engulf it in her hot little mouth.
Sucking her stepbrother off revs up a real unexpected desire in Harley. She doesn't wait for permission before she wiggles out of her shorts and sinks down onto Codey's hardon to ride him in reverse cowgirl. Turning around, she makes sure that Codey is now openly admiring her incredible breasts with their dark brown areolas and one sexy pierced nipple. Flipping onto her back, Mia spreads her thighs nice and wide to encourage Codey to give it to her. Now that they're equally culpable in their stepsibling coupling, Codey commits entirely. He flips Harley onto her knees and does her in doggy, then gets her on her side so he can hang her to a close call for a creampie. Pulling out at the very last second, Codey covers Harley's ass in cum and leaves her smiling and feeling like her time has been better spent than if she had played video games.
