Mark is enjoying a nice day off by the pool and trying to get a good tan. While he's putting on some tanning oil, he decides to give his step daughter a call to see if she can come outside and help him cover his back. She comes outside and can't stop looking at his body. She begins to get really horny and decides to try and see how far she could take it. She slowly starts rubbing his back with oil and convinces him to take off his shorts so that she can rub EVERYWHERE. She assures him that her mom won't ever find out. He was nervous at first, but it felt way too good to stop her. She gives him a slow and sensual handjob before asking if she can suck it. She then gives him an amazing blowjob and they begin to fuck before mom gets home. He leaves her with a huge cumshot all over his face and they both enjoy their new dirty little secret.
