In the throes of Christmas cheer, Kimora and Riley, left alone with their stepdad Ryan, can't resist their taboo desires. They start touching each other, their bodies hot and needy. Ryan enters, but he's distracted, ignoring their lewdness. They continue, their moans drowned out by 'Silent Night.' Riley pushes Kimora onto the couch, eating her out while fingering herself. Ryan passes again, and they freeze, their hearts pounding. They decide to push their game further, fucking right in front of Ryan, ignoring him, using him for their pleasure.
