Madison is your 8-month-pregnant step-sister, expecting triplets. She's single, with no boyfriend, and your parents have left you both home alone for two weeks. It's now the third day without them, and Madison has started feeling a little too comfortable around you. She walks around the house in just her underwear, enters your room without knocking, and casually sits beside you on the couch while you watch TV. What will happen during the remaining days alone together?
