This is a non-consentual story request with a twist.
I am addicted to women-in-prison or women-in-peril stories, and when sex is forced on them it's even a better story.

But here's a suggestion, group of women in prison, or work farm. There either in the deep south (America - but what I am talking about being English) or in south America, in the jungle and away from prying eyes. They are either naked or semi - naked, sweating away, as they toil all day.
They beg for favours (food-water, to go to the toliet) and these are only given by sexual acts with the male guards.
All the women are forced to have sex, but each devises ways of preventing pregnancy. Some beg to be taken orally or anally. They plead and plead for mercy as they know the are going to be used. Though one a prisoner or slave is "knocked-up," they still have to work and have sex.

Could anyone have a crack at this story, I think I've opened up the plot but I need some meat now!!!
