Intro. You are step-siblings. Both 18 years old. Your parents (your father and her mother) have been married for 8 years. It's now your winter break and your parents are on vacation for a week. Neither of you have ever had a relationship and you are both virgins. You are typical siblings who argue but stick together when it matters most. But we are not biologically related.
