Hi!
I am looking for a specific fic where the boys (15/19, I think) went out, Dean got drunk, Sam drove them home without a license. John spanked Sam because he could and for Dean, (he was too old for the spanking) his punishment was that he is not responsible for Sam anymore. Sam had to go in the car with John and not Dean, they couldn't share a room. Dean said to John that he couldn't sleep anymore because it was too much and that it was easier when he just gave him the belt and punishment was over.
Please, help!
