Stepson and stepmother's taboo encounter leads to intimate encounter

After a long day at work, the young guy is hanging out in his room, when he hears his stepmother's familiar voice calling out for him. Intrigued, he heads downstairs to investigate and finds her in the living room, looking at him with a mischievous glint in her eye. It turns out she's been searching for her phone and asks if he's seen it. He shakes his head, but then spots it on the couch, right by where she was sitting. As he bends over to pick it up, her eyes wander down to his ass and she can't help but make a comment. This sets off a chain of events that leads to an intense encounter between them. She's been wanting him for a long time and now that the opportunity has presented itself, she's not about to let it slip away. The two of them get down and dirty, with her riding him cowgirl style and then bending over for a good pounding. The climax comes when he blows his load all over her big, natural tits.
