Several Sci-fi ideas

1) Lone space pirate capturing a family for his own fun. It should be normal, not female only. Say: Father, mother, son, and twin 18-year daughters, so pirate will have choices from killing males to using them as hostages for the obedience of females to forcing **** for his own fun

2) Cargoship with several females crashed on male only isolated prison planet, but with nice character development story, no woman enjoying **** for no reason and no "every male likes ganbangs instead of getting female for his own use

3) Some rich guy purchasing a top class android made for sex... Later he falls in love as android transforms from an empty doll to real person

4) Interrogation of captured female soldier... With such idea : interrogator is pretty soft person with loving wife, no obvious sadistic tendencies and have zero experience in torturing, but he NEEDS that information and captive is hot. Of cause it can go in other categories, our time or fantasy, but scifi seems funnier due to more options
