Tony finds his stepsister Alex Grey in her bedroom just as she's confessing to her boyfriend that her parents are both gone for the weekend and she'll have to sneak him in. He catches her whipping her titties out to send dirty pics and takes the opportunity to snap some picture evidence of his own. Then he makes his presence known and lets his sister know that he knows what she's up to. Alex tries to play the injured party, but Tony makes it clear that he's in charge. Alex agrees that she owes Tony one, so he decides they're going to fuck it out.

First he gets Alex to show him her tits. Her perky little jugs are the perfect appetizer as he asks Alex to show him her ass. When Alex tries to put a stop to it, Tony points out that he's hard and that Alex shouldn't leave him hanging. That's the point where she admits she's thought about sucking him off once or twice before, so he gives her the chance to live out that fantasy with his big dick in her mouth.

Alex gargles Tony's balls and sucks him into a deep throat before straddling his fuck stick and sliding down for a cowgirl ride. Turning around for some reverse cowgirl action, Alex spreads her ass cheeks so Tony can admire her chocolate starfish as her bald pussy engulfs him. She lets him have control as she rolls onto her back, but she's soon on her knees to take a doggy style pussy pounding while her stepbro's hands roam her ass. Alex seals the deal with another BJ where she sucks her brother off until he pops in her mouth to give her a nice treat to swallow.
