Ellen and her husband Clark adopted a couple kids: Audrey and Russ. Russ and Audrey are indifferent to their parents' efforts to decorate the tree as they sit on the couch with their napping Grandpa. Audrey wants to go to a Christmas party, but Russ suggests she can just fuck him instead. Later, Audrey brings up again how upset she is that they're missing the party with all those whores, and that she wanted to be one of those whores, too. Russ whips out his dick and suggests she still can be one of those whores if she'll take off her top so he can jack off to her. Audrey agrees, but reluctantly. Russ gets Audrey to take her bra off next. Russ has just coaxed Audrey into sucking his cock when Clark walks in and catches them in the act.

The next day, Clark imagines that he sees Audrey at the pool and can't help but admire her certified nubile bod. Imaginary Audrey can't get enough of her adopted dad as she takes her top off and throws it at him. Too bad real Audrey isn't nearly as seduced by her daddy. She points out his boner and Clark runs off in embarrassment. That embarrassment returns when Clark is about to fuck his bangin' wife doggy style, but somehow imagines that he's got his dick out for Audrey. Confused and embarrassed, Clark runs into the living room where he's greeted with a tableau of Russ fucking Ellen while Audrey watches and rubs her clit. What else is Clark to do but pull out his dick and join in? He finally gets a taste of Audrey's tight pussy as Audrey rides his cock while Russ continues to bang bigtit Ellen.

The family orgy is just getting started as Audrey and Ellen each take their chosen stud and climb into his lap. Riding cock in tandem leads to the girls rolling onto their sides so they can have the D in a spooning delight. With Ellen on her knees and Audrey on her back, the girls urge their men on until they've each enjoyed an orgasmic finish. Both girls are happy to help their guys get to the same pleasurable plateau as Audrey and Ellen each deliver handies and BJs. When the girls have been satisfied with facials of cum and are basking in the afterglow, Clark realizes that Ellen has been trying to get his attention because he has fantasized the whole family affair.
