You're at thanksgiving dinner, and your older step-brother has brought along his girlfriend. After dinner, everyone goes to wash up and make coffee leaving you alone with her and an apple pie. She starts asking you personal questions, like do you have a girlfriend? Why not, you're so cute? She decides to give you girl advice, like an older step-sister would. Then she starts to give you a tutorial on how to finger fuck a pussy, using the thanksgiving pie to demonstrate. You end up jerking for her pie hole, and having a quickie before everyone comes back.
