Carla and Karlie Johnson had a birthday tradition, Dare. It was like Truth or Dare for people who already knew everything about each other. Taking naked pictures of each other for insurance, they took turns daring each other to complete humiliating tasks. If they didn't, their picture would go all over social media. This year, since the twins are turning eighteen, they decided to up the stakes and make their dares more mature in celebration of their adulthood. For Carla, it was all about fulfilling her incestuous desire, but for Karlie, it was more about bestiality.
