If you don't mind other authors to contribute, it could go as JRaven suggested a series such as:
"Blackmail Blowjobs: Fellatio to Freedom" lol....just picking off the INS agent story idea
"Blackmail Blowjobs: It's All About the Rent" - the stripper need to pay rent idea
I like the "all about the rent" Idea but I think a stripper is a bad choice in this situation because she is familiar to sexual surroundings. i think it should be someone with no heavy sexual experience say a young single female or single mum struggling in her job with not much money.
