A Good Type of Mistake

Dean Winchester is an 18 year old high school senior who is brilliant, charming, and attends a few too many parties. Castiel Novak is a fellow senior and is as studious (and single) as they come.
Dean went to a friend's house and was up partying and drinking. When he attempts to go home, he finds himself in the wrong house and ends up in bed with his neighbor and long-time crush, Castiel Novak.
