Found!: Tony didn't escape from Ten Rings, forced pregnancy, escapes to Wakanda with Bucky
The fic I am looking for is a slightly darker one, where Tony never escaped from Ten Rings, and spent years in captivity. He was forced to bear children with the DNA of the Avengers, and eventually escaped along with Bucky, who I think he knew as Winter. They crossed the desert and ended up at the borders of Wakanda, where T'Challa took them in.
The story focused on how Tony and the children dealt with their traumatic experiences, and the reactions of his friends to his reappearance, although I know all the Avengers made an appearance later on.
I'm not sure if it was mutant!Tony, Omega!Tony or something else, although I think at least one of the children (Thor's) had powers. I can't remember where I first read it, and no amount of searching has been successful, so any help would be much appreciated!
