It's Christmas Eve and you sneak downstairs to see which gifts are under the tree. You spot your step-sister lying there in sexy lingerie. She's up late and horny, and she's now hungry for your cum. She mocks you a little and tells you to give her what she wants like you've done so many times before. You give in and cum in her mouth, which she then dribbles onto the floor in front of you. Loads of dirty talk throughout!
