When Kenzie Madison and her stepbrother Brad Sterling go to their aunt's house, they have to share a room with a bunk bed. Brad becomes freaked out by the intense sexual tension that exists between Kenzie and him. When Brad tries to talk to his mother, Claudia Monet, about his worries, Claudia responds that it's common for girls Kenzie's age to be interested in things sexual. In order to normalise it for Kenzie, she proposes that Brad show her his dick. Kenzie gets a close-up look, but Claudia forbids Kenzie from touching. After instructing the youngsters to settle comfortably, Claudia departs. They retire for the night. Brad sleeps in the bottom bunk. That night, unable to sleep, he inquires as to Kenzie's whereabouts. When she doesn't answer, he beats his flesh by pulling down his boxers. After giving him a brief moment to touch it, Kenzie asks if she can watch or even assist. Brad doesn't give up until Kenzie asks if this will help him cum and sticks her butt out. Brad eventually gives it another stroke since his stepsis is too attractive to ignore. Brad lets Kenzie try to put her hand in place of his once more. She leans in and begins to suck him down in a BJ that Brad isn't too keen to stop. Brad doesn't cum, even if Kenzie takes her time. As she gets on her hands and knees, she says it might come sooner if he fucks her. Brad thrusts his dick balls deep into that juicy twat without even debating. Kenzie climbs atop Brad's fuck stick and rides him all the way inside her hairy snatch when doggy doesn't do it. Their acrobatics are considerably easier because of the bunk beds! By now Brad is intent on getting his stepsis off one last time as she lays on her back. Brad is about to burst himself, but before he can do so, Kenzie encircles him with her arms and knees to keep him within until he blows his load for a creampie.
