Seth Gamble never imagined that his parent's new trophy wife, Andi Avalon, would be around the same age as him. It feels weird to refer to her as his stepmom when their ages are similar. But Seth's situation is about to get even weirder. His parent is currently recovering from a skydiving accident, so he can't move around much, and Andi is upset about it because it means she can't have sex for a while... unless Seth has sex with her! Seth is completely shocked at the idea, but Andi insists that she craves sex all the time, so if she doesn't get fucked, she's going to stray. She says that Seth needs to step up and be a hero so she won't go looking for strangers to have sex with. Seth agrees to do it for the sake of his family. He has energetic sex with Andi, including giving her a creampie!
