If 2 people (a man and a woman) were lost and stuck in an island for a while, maybe say a few weeks and they had no food or water, and the woman was lactating, could the man live on her milk and the woman live on the mans sperm for a while ( To just survive and make it through the ordeal )
There are real life accounts of people drinking urine and surviving in trapped buildings and others going without food or even water for days after getting lost in the forest.
I am more interested to know if the woman can survive on the man's cum and if so how long can she do this for without other food ? Yes I am aware a woman would have a lot more supply of milk compared to the amount of sperm the man could provide.
I am thinking of an erotic story in my head with this particular theme - It starts as a basic necessity for food but soon turns into an erotic pleasure for both. But I am also trying to keep the plot realistic.
How long could they do this for before it just wouldn't be enough to keep them going ?
