Demi Nova is planning a family vacation with her husband and his son, Juan Loco. Juan has been having a hard getting used to having such a hot woman in the house, so he often gets tongue tied around Demi. He comes into the kitchen to talk to her, but forgets what he was going to say when he gets a glimpse of that ass. Demi eventually sees Juan and reminds him that they need to leave early tomorrow so he should go to bed soon.
Later, Juan happens to pass by Demi's bedroom right as she and his dad are getting it on. He learns by listening in that his dad is basically a two-pump chump who's leaving his hot stepmommy unsatisfied. When Juan hears Demi getting up, he goes to his bed and pretends to sleep. Demi crawls into bed with Juan and asks if she can sleep with him because his dad snores loudly. Juan says it's fine, so Demi finagles it so that she's spooning with her ass against Juan's waist. As soon as she feels his hardon, she begins grinding against him in earnest.
Juan is uncertain at first, but Demi presents a convincing case that he should fuck her. Once Demi gets her lips and hands wrapped around his hardon, Juan is soon happy enough to along with it. He obediently removes Demi's panties when she gets on her hands and knees, then slides it in so he can give his stepmama the entire length of his cock. Demi glorifies in multiple positions as she rides Juan in reverse cowgirl and then takes a pussy pounding on her back. She even gets the big finish right in her face as Juan pulls out to cream all over her titties and face.
