I'm piloting a starship to a new colony world, with three hundred frozen colonists and a dozen hibernating girls. I have everything the new colony will need plus an enormous quantity of liquid food, in case the new planet isn't very fertile. Halfway there I realize the food tanks are leaking into space. If the new planet isn't perfect the colony will starve. The girls are fed a trivial amount of food every day, but I could hugely increase that and give them hormones to make them store the food in their breasts before it's lost. That sounds easy but I don't know if they'll survive. If we make it I'll have to face what I've done to them, and the colony will probably shoot me, but first I have to get us there.
