Harley King and Alex Mack are brand new stepsiblings who are still working out how to live together with their newly married parents. It doesn't help that ever since the wedding their parents have been all over each other, in all parts of the house! Today, Harley and Alex's parents are going at it loud and proud in the living room. Alex dips into Harley's room to get away from it. Harley invites Alex to get into the bed with her, but he decides to sit on the floor. While Alex is playing on his phone, Harley decides this is the perfect time to start running her hands all over her curves. By the time she pulls her thong aside to really go to work on her bare pussy, she can't hold the moan any longer.
Alex notices and tries to leave, but now he's stuck between his masturbating stepsister and his sex crazed parents. Faced with two bad options, Alex chooses Harley. When Alex reenters Harley's bedroom, she claims that he must be perving on her and demands that Alex come closer. Before Alex knows what's happening, Harley reaches out to touch his dick! She claims she doesn't feel anything and asks if Alex even likes girls. Pulling his pants down, Harley sees that she has indeed been mistaken. Bonus, her new stepbro has one hell of a nice dick! It takes a bit of coaxing, but Alex reluctantly agrees to let Harley suck him off so they can try to ride out their parents' sexcapades together.
Once Alex feels how hot his stepsis's mouth is on his cock, he begins to change his mind about how wrong it is. He feels even more confident as he gets his first glimpse at her fine titties with their pierced nipples and her nice round ass. When Harley turns around and peels off her thong to invite Alex to come inside, he takes her up on the offer. Harley stays in charge as she pushes Alex onto the bed so she can climb on top of him and slide down for a reverse cowgirl stiffie ride. That position gives Alex plenty of hands on time with Harley's ass, but turning around for a cowgirl ride lets them get rough and wild together. Falling onto her back, Harley welcomes Alex back between her thighs as she guides him harder and faster with her moans. Alex can't help but give that fine pussy a big fat creampie that leaves them both content and sated until Harley kicks Alex out of her room.
