Aria Valencia and her stepbrother Nathan Bronson have been fighting nonstop since their parents got married. The newlyweds are sick of it. They decide to lock Aria and Nathan in a room and refuse to let them out until they figure out how to exist without arguing. At first Nathan and Aria hang out in their own corners of the room, but eventually Aria decides that she's bored. The only thing that will make it better is for Nathan to strop off all her clothes and fuck her.
Nathan tries to deny that he's attracted to his stepsister, but Aria claims she knows how he looks at her and she refuses to be dissuaded. Nathan eventually does as he's told. The way the stepsibs still feel about each other is obvious in their rough handling of each other, but that doesn't stop them from taking some pleasure in their encounter. Nathan goes from some light breath play to palming Aria's tits. Then he pushes her panties aside and just shoves those fingers right into her greedy twat to find her nice and wet for their encounter.
Flipping Aria onto her hands and knees, Nathan drives home in doggy. He grabs her by the neck to bring her up, then traps her arms behind her back to keep her pinned as he pistons in and out of that tight twat. Aria is here for it, moaning and squealing as Nathan gives her what she wants. When Aria rolls onto her back and spreads her thighs, Nathan gives her the full D. They take a break so Aria can deep throat Nathan in a 69. Moving on to Aria riding Nathan, she puts all her disdain into taking that big dick nice and hard. One more round on her back and then Aria strokes the cum right into her mouth as she brings Nathan off. It turns out these stepsiblings don't have to like each other to have fun together.
