So you thought it would be fun to tattle to mom and dad on me and get me grounded for Christmas huh? You knew I was supposed to go camping with my friends over break! Well, I guess you can't help it that you wanted me all to yourself. All our lives, I could tell you've been lusting after me, your very own sister. Since I can finally see how desperate you are for me I'll give you a Christmas gift you'll never forget. I even wore a special outfit for you. I start stroking your cock until it's rock hard and throbbing in my hands. I even take my tits out and wrap them around your cock, fucking you with my tits. Talk about best Christmas ever! I keep stroking your hard cock until you explode cum all over the place, quickly taking my hands off the second you start to cum. HAHA!!! You fucking loser!!! This should teach you not to ever ruin my Christmas again!
