You and your younger sister are sharing a room while you're visiting family for the Holidays. She comes back to the room after going out to a Christmas party and having a few with friends! She's sooo horny she tells you she was planning on playing with her pussy that night, whether you were there or not... but, since you ARE here you may as well watch! Before long she's sliding her panties to the side and admitting that this is what she's wanted for a long time. Your cock is getting so hard, and she knows it! She starts begging you to pull it out and stroke for her. She keeps convincing you and begging with you until finally she asks you what she's really wanted for Christmas all along - her brother's cum all over her tight little pussy! Unable to resist, you give her the cum she's been craving.
