I read this story few weeks ago on lj...it had sam wetting the bed after a nightmare and dean then cleaned him up..they next night sam fell asleep while a movie and dean put a pull up on him while he slept...next day sam freaked out when he saw the diaper but in the end dean convinces him to use diapers and to rely on him and let him take care of him...it was set in season 1

Also any other story of adult sam wetting the bed and dean cleaning him up later would also be great :D

Thanks in advance!
