Mackenzie Moss just got done eyeing a thriller flick and now she's appalled to shower alone in their vaca home. She asks her stepbrother, Seth Gamble, to guard her without peeking. Seth decides it'll be funny to prank Mackenzie, so when she gets into the douche he runs to the kitchen and grabs a knife to pretend to replicate the video's penultimate gig. Mackenzie runs off to her guest room to sob. Seth senses painfully, so he decides to apologize. Mackenzie asks why Seth is being such an backside since she thought he enjoyed her.Seth tries to apologize again, putting his mitt on Mackenzie's hip. She calls him on it, but when he eliminates his arm she puts it right back, but higher. He takes the hint, frigging his sister beneath the towel. In come back, Mackenzie tugs Seth's pants off so she can wrap her lips around his hardon. Deepthroating him off, she deep mouths Seth's beefstick until she can't wait another moment to mount top and commence riding him. Mackenzie is so tiny that Seth finds he can do all kinds of acrobatics with his stepsister. He raises her to set the rhythm as she rides him, then dominates her from above when she falls backwards onto the sofa. Getting onto her hands and knees, Mackenzie invites Seth to give her a doggy style muff nailing. As he bangs her, she prays him to jizm inwards. He obliges, glutting her with a creampie that cascades down onto the couch when he pulls out.
