i thought about a story set in this fictional semi fantasy kingdom where the main export is dairy. the secret is that the milk is human milk, there are these big farms where all women in the age of 17-20 have to go and be milked. kind of like the mlitary service.
now the kick is that the kingdom is seeking to double its production of milk so the queens decide to conscribe the male population into the farms as well, much to their chagrin.
the story would focus on this teenage boy who is not comfortable at all with the deal but has to go do it anyway and the long and slow process of him first having to develop mammary glands to be milked and then him getting used to be milked five days a day while surrounded by other women being milked as well ( he is the only male of his tiny town that was conscrived)
of course the goverment would make a huge deal about how the people in the farms are actually doing a great service to the community, again, much like the military, and so he would grow to have a real sense of pride over his new place in life.
cut a couple of years forward he is the plumpiest, bustiest and proudest milk maiden of his town
