You were Deans girlfriend. Before you two started dating he had a new girlfriend every week; but you guys had been going out a few months now.
It was after school and you walked home with Dean. Well- to his motel- not exactly a home, but close enough. His dad was making Dean and his brother, Sam, stay at the Motel until he found a good house- apparently. You'd already told your parents you were sleeping 'at a friends house'- of course, they had no idea your 'friend' was a boy...but that didn't matter.
Sam had taken the bus home and Dean almost forgot he was in the motel as he started kissing you as soon as the motel door opened. "Sammy-" Dean grins, pulling away from the kiss. Sam looked up at him, half smiling, half disgusted at the kissing- but he seemed accustomed to it. "hey, uh- why don't you go to the arcade or somethin' bud?" Dean looked through his wallet, trying to get rid of Sam so you and Dean could be alone. sam sighed and nodded, waiting for the money. You didn't want him to go, you loved Sam- he was a cute little thing. You hated that Sam and Deans dad never spent time with them. What a deadbeat. He was missing out.
