Your sister is back home for Christmas, you've been so excited to see her, you bought her a really nice gift. But she's been wearing tiny hot pants and a little top all day, and you can't help but look. You're so embarrassed you hide away in your room to remove temptation, but your sister follows you up. She asks what's wrong, and tells you how much she has missed her brother, and can't wait to spend some quality time with you over the holiday season. You become more relaxed, even if she is wearing short sexy clothing. You give her your gift, and your sister is so happy, but feels so bad, she didn't have time to get you anything. Your sister feels so guilty, is there anything she can do to make you forgive her? You must want something for Christmas.... And that's when you tell her, all you really want is your sisters pussy.
