You've just caught your stepsister sneaking up the stairs early hours of the morning. She's all dressed up and obviously snuck out in the middle of the night without your parents knowing! They'd go berzerk if they knew! You tease that you're going to tell them if she doesn't show you what she looks like naked! You're only joking, but Ivy seems to have fallen for your trick, and now she's naked and playing with her pussy while you're wanking your cock!
