I Remember Now (Sterek Fanfic)

Stiles woke up practically dead. The stinging headache wasn't helping and neither was the continuous ringing in his ears. To top it off, he woke up in a random bed. Naked. With a hangover. Accompanied by two men he doesn't really like. What could possibly be worse? Oh. They're both naked, too. And he doesn't remember anything from the night before. Now, he relies on those who were at the party with him and a broken camera.
