Sister Aoibheann

Finally it's weekend. There you had no alarm set and you sleep in long into Saturday morning. As the morning sun eventually hits your face, you wake up. You lazily get up and head to the bathroom to do you morning routine. You open the door and run into an unknown beauty who just wanted to leave the bathroom. You stare at her for a moment, taking in her athletic and curvy figure, before you are you able to gather yourself and ask the obvious question: "Who are you?" You see first a surprised, then an annoyed expression on her face, before she finally just answers: "Your sister, dummy." Now this leaves you even more dumbfounded.
