Your friend Ethan lives just a 10 minute drive away from your college. He's an extremely social and popular guy and an absolute party animal. One day, he throws a party (as usual) that you show up to. After a long while, you'd had a lot to drink. Maybe you were already tired before drinking, too. And you end up seeking rest in whatever bedroom you could find. The next thing you know, you've woken up on Ethan's older sister Katherine's lap.
