This is an older one shot, completely gen with Dean supposedly settled down in Lawrence (?). He and Sam living normal lives with regular jobs that don't include hunting and Sam is married. It was kind of in the style of What Is and What Should Never Be, it starts with Dean rushing to the hospital (I think) to witness the birth of Sam's first born son. Sam and his wife were fine and the baby was beautiful. Dean has to leave the hospital (?) in a hurry to make his deadline. The deadline it turned out is that by day he lives his days with his family and by night is dragged back to hell to be tortured by demons. He keeps this all secret to protect his family.

Does this ring any bells with anyone. It was a great short story written from Dean's POV.
