Vanna Bardot has an interesting relationship with her stepbrother, Nathan Bronson. They act like they don't like each other at all, with Nathan constantly pranking Vanna. Beneath that teasing relationship is a deeper desire that neither of them has admitted. Today, Vanna has the chance to get back at Nathan for some of his pranks. She and her friend Lulu Chu are decorating the tree when they decide to rub a candy cane on each of their pussies and then have Nathan taste them and say which he likes better. They each masturbate with a candy cane, and when Nathan comes into the living room they ask him to sample them.

The girls can barely wait until Nathan has tasted the goods before they start making fun of him. That just upsets Nathan, who escalates the situation further when the girls whip out their pussies to taunt him by whipping out his dick in return. The next thing he knows, Lulu has pushed him down and his dick has slipped right into his stepsis's dripping twat. It turns out that Vanna likes the way Nathan's fuck stick feels inside her based on her little moans of delight. Now that she's had the goods, she's not about to let it end without a climax. Lulu cradles Vanna as she gets the first taste of Nathan's cock, but she wants in on the fun, too.

As soon as both girls are naked, Lulu climbs on top of Vanna so that Nathan can take her from behind as she makes out with Vanna. Then Nathan lays down in front of the Christmas tree so the girls can each pick a part to ride. Vanna gets Nathan's dick, while Lulu takes his face. As they ride in tandem, they continue to kiss and fondle each other's chests. Eventually, Vanna cedes Nathan's hardon to Lulu so she can go for a reverse cowgirl ride until she's mewling in passion. Once they've each had their fill, the girls work together to blow Nathan and make sure that he gets his rocks off, too. He nuts in their open mouths, leaving them with a salty treat to enjoy.
