I'm looking for a Bones xover fic where Bones makes a comment to Dean about wanting to have his baby because of his good looks/genetics. I think it was set in season 4 or post season 4 SPN. I think Dean was also upset about the request. Been trying to find it for a couple of days and have not had any luck. I've looked at all the SPN/Bones crossovers mentioned here and have been all over Google. Any help would be appreciated.
