This rp would deal with woman being held as prisoners of war on another planet. They would be subject to the whims and desires of the male and female guards of the prison. However if they play their cards right they may not be tortured indefinably. Perhaps they can seduce one of the men and woman who guard them and thus be given special privileges. From there they may incapacitate the one they seduced giving them an opportunity to catch a ship back to Earth. Or they may be caught doing so and be tortured.
This can go many ways. Maybe they are used in experiments and these experiments may damage them or give them powers they have not had. If the latter is the case then perhaps they can use these to free the other prisoners and escape back to earth or perhaps they would only be more amusing toys to the guards who are seeking to exploit and take advantage of them.
All of this would be subject to discussion as I am not tied to any one scenario.
