As the clock strikes midnight, the cousins, wrapped in a shared blanket, confess their long-held secret feelings. The girl, her voice barely a whisper, asks, "Would you be my first, cousin?" He nods, his cock already hard at the thought. She straddles him, her virgin cunt sliding down onto his shaft, making them both moan. They move together, their bodies slick with sweat and desire, their kisses hungry and unrestrained. The room fills with the sound of their pleasure, their bodies slapping together, their moans echoing off the Christmas decorations, creating a taboo holiday memory they'll both cherish.
