I've had some more ideas to add a twist to such a story.

Women-in-prison, imprisoned for capital offence, as suggested by others. therefore, no questions about what happens to them.

So how about a baby selling story. Pregnancy is not intentional, but when it happens the babies get sold onto the wealthy people of the country. This fits in with the story being in a jungle or swamp land, hot and sticky situation.

All the women have to barter to better food, or conditions and even those that are pregnant have to offer themselves to anyone for anything. Though they are made to work as hard as everyone, to toughen them up. Those that aren't pregnant offer themselves orally or anally to avoid the same sitution as they see how difficult a life it is, when "knocked up."

Maybe some of the women pair up to "clean" each other out when they have been used.

Graphic details about how miserable, dirty and sweaty this life is would make a fantastic story. read too many that talk about women have loads of sex and they never seem to have a drop of sperm inside or on the outside to prove it. A gang bang and the victim walks home, without feeling sore or is as claen as a new born baby, I'm sorry lets get a bit of life into these stories.

So anyone to have a crack at this?
