Good Cuckold story

I came across this good cuck story. Here is the link, it starts with the cuckold theme and slowly evolves into a unbalanced polyamorous relationship and culminates with the wife getting impregnated by her black lover. The title is Navy Wives-Erica. Here is the link The hyperlink is visible to registered members only! . Can anyone post a link to other stories with similar themes?

I read the first chapter, just brilliant, holds so much promise of what is to come. I've gotta go and catch the rest now. Good cuckold/IR theme to it.
