Thanks for the reply. Yeah I found both those stories in my search, but they are not it. Carl Bradford, joe day and a couple others are definitely in the vein of the story I'm looking for, but I'm 100% sure it's not on literotica anymore. I would've found it by now. If only there was a way to search my old favorites list by year, cause I'm positive I had it favorited at some point.
I've also been remembering a little more of the story, the legal slavery was separated by countries. I remember the Mc getting on a plane when her ordeal was over and she was sent to another country, I think by some government agent. The USA was the primary country for legal slaves, and there were some middle Eastern countries as well. In one of the beginning scenes when she was with her friends family, her friend and her friends brother toyed with her in bondage to help get her used to the process. And I believe she was also a lesbian so she had a lot of anxiety getting used to men. Eventually she was brought upstairs to serve her friends mother, and her friends mother helped get her used to serving men by using her husband. She joined the maid service from then on and served the family as a slave for a trial run for the weekend I believe, before going undercover.
It sucks that I remember the beginning so well but can't find even a whisper of it online, I've search for hours lol
