Kyler Quinn is closer to her adopted cousin Roxy Ryder than the average family, as evidenced by the way the girls enjoy putting on lacy lingerie bras and panties and masturbating together. The cousins have both got the hots for Roxy’s stepbrother, Nathan Bronson. They have a plan, but they need help bringing it to fruition. Now that they’ve both climaxed, the girls get dressed and go to find Nathan’s mom, Katie Monroe, to enlist her assistance in what they assure Katie is an April Fool’s joke. Later, Katie pulls Nathan aside and tells him that it would be her dying wish to see him get together with his stepsister. Nathan is confused, but he says he’ll get it done.Nathan goes right to Roxy’s room to talk to her. Kyler excuses herself to give the two some space and Nathan gives her the rundown. Roxy plays shy, but Kyler is suddenly there to make sure the deal gets sealed. Kyler slides Roxy’s hand onto Nathan’s dick. When the girls find it nice and hard, they pop it out to work together to deliver a double BJ that really gets Nathan in the mood. Kyler continues to lead the way as she slips out of her thong and miniskirt and straddles Nathan’s thighs so she can slide down on his dick until he has filled her all the way up.Now that Roxy has enjoyed the sizzling sight of watching her cousin fuck her stepbro, she wants in on the action. She gets up there so she can ride Nathan in reverse doggy. Kyler once again finds herself in the middle as she lays on her back with Nathan pounding between her legs and Roxy riding her face. Then Roxy gets her turn in the middle as she feasts on Kyler’s muff while Nathan gives it to her doggy style. She flips onto her back and moans with delight as Nathan keeps on fucking. He pulls out when he’s ready to cum so that Kyler can aim his jizz at Roxy’s stomach. The trio are just basking in the afterglow when Katie comes in and realizes that the supposed prank she participated in was more like the real deal.
