Uh oh... your stepsister Tamsin Riley took out the car without permission and she managed to bang it up. She KNOWS that it'll be the end of the world when your folks get back, so she desperately needs you to cover for her. You're not an idiot, though, and you're not putting yourself on the hook for something she did without getting something out of it. And you know EXACTLY what you want from your sexiest (not to mention horny) young stepsister to keep her out of trouble...
