Fics like Wanna Bet?

Mark and his thirteen-year-old sister made a bet to settle a silly disagreement over the star of a movie. If she was right, he'd be her personal chauffer. If he was right, she'd give him blowjobs for a week. He was right, of course, but as time goes on, more bets are made, with higher stakes, and Mark starts to wonder if his sister is enjoying these sexual games, and possibly even losing on purpose.
