You and your sis are hanging out one day in your room when your sister starts complaining about how bored she is - she's got 3 weeks left before she goes back to college but none of her friends are around and she's sick of being stuck in the house! Your parents will be out for hours so she suggests you play a game with her. How about truth or dare? After a few questions about your dating life things get more interesting as she quizzes you on when you last jacked off, where's the weirdest place you've done it etc... You ask her how many guys she's been with and she suddenly notices that your cock is getting hard... You deny it but when you take a dare she dares you to get it out! You try to argue but she tells you that you have to follow the rules! So you get it out and the game continues... After a few more questions and dares it's obvious to both of you that your cock is definitely hard! You dare your sis to take her top off, and then she decides to take it up a notch - she dares you to jack it! You say no way, that would be too weird, but she says if you don't play along she'll tell mum and dad about the time she saw you stealing money out of dad's wallet last summer! You have no choice but to jack it in front of her as she watches, and after a while you insist she takes her bra off so you have something to look at. You freak out a bit then at what's happening and try to stop but she insists you keep going, saying will you keep doing it if she does it too? You try and resist but you give in and she strips off completely and starts touching herself while you jack it. She teases you about being a perve as you get closer to cummming, and then informs you that if you cum before she does she'll tell mum and dad about that money!
