Im not so much into the cuckold stuff, but some of it is pretty hot. I do like when the husband suck the guys cocks when the wife tells them to. But I will have to look into the movies that you mentioned. Are they on netflix?
I know you can watch short clips on sites such as X Hamster, X Videos,
And Youtube ( Search Cuckold Queen ) or Bitter Moon, Unfaithful.
Not sure about Netflix.
