looking for a specific story and similar ones

It is in the cuckold genre, and I do not need any judgemental replies about my interest in this fetish that I so often see. I read it on here awhile back. husband takes his wife on a vacation where he leaves her alone with a black man with hopes of her seduction which is inevitably successful although she is initially somewhat reluctant. I am also looking for other cuckold genre stories that are similar where the wife is initially somewhat reluctant and is seduced. also stories where wife dates and finds a steady serious boyfriend which alters her relationship with husband, also, of white wives who with some encouragement have moved on to black men only. some stories I have liked in the past are, caught, cuckold paradise, and a new one that is developing nicely called the evolution of moira

come on guys, someone help me out
