Searching for witness protection story

I'm looking for a story about someone who transitioned as part of a witness protection program. I believe he was in the FBI or CIA. He had been a crossdresser as a man. As a woman, the witness protection program helped her fake a pregnancy and eventually breastfeed. She fell in love and also met up with her former wife. I may have seen this as much as a couple of yeas ago. Has anyone seen the story I am asking about? Know where I could find it? It might not have been from BigCloset. Thanks!
