In this variation on the schoolyard classic, Kat and her older step-sister Sam make a best 2 out of 3 Rock Paper Scissors challenge! Each round, the loser gets a 1 minute bare bottom spanking. The first person to win 2 rounds gets to dare the loser to do something during their last 1 minute spanking. Will Kat get the dreaded hairbrush, or will Sam go topless during it?
