You catch your sister sneakily checking the presents early Christmas morning. She denies and then admits, she was checking to see how many are for her. She finds one without a tag and wants to open it, you tell her no and you’ll wake mom and dad up. She brushes you off and peaks at it anyways. Its a gift for Mom from Dad. She still wants to see what it is. Now she’s pissing you off and you say no again, but she does it anyways. Dad bought Mom some sexy lingerie…but you can’t help but wonder what it would look like on your Sister so you tell her to put it on, or else you will tell. You can tell she wants to. She puts it on and it gives you a boner. Now you tell her to touch your dick or else… Reluctantly she does it so she won’t get in any trouble. All of a sudden Daddy wakes up and catches us in the act. Daddy is so mad she’s wearing Mommys lingerie.. but Daddy acts weird and seems to like it. He tells her to keep stroking. Then to fuck. She slides your cock inside her and lets you fuck her. Your Sisters pussy feels so good you cum inside her. Now she turns around for a second cream pie. Daddy wants a turn now. Daddys cock is much bigger and much more experienced. He stretches her out and fills her pussy. A big cream pie spills out and then he fucks her in doggy style for another cream pie. Thats what she gets for opening gifts and looking so good in Mommys lingerie. Now Daddy helps her wrap it up to put back under the tree.
