I've been learning, so I know the answers to most of those questions now. Except the interracial pregnancy. I understand that there are couples who get off to knowing the wife is carrying another man's child, but brown babies are kinda hard to explain to the in-laws.
The Hotwife Lifestyle has nothing to do with pregnancy, or having another man's baby. There is nothing in this story related to pregnancy, or brown babies.
The mega links say no longer available? Is this still available?
i can assure you, asking these questions means lack of sexual experience for people who enjoy swing and group sex activities. If you are asking about why this is a fetish; probably one of the oldest form of fetishes out there are orgies, swinging and gangbangs. You can search ancient times and hedonism practice if you are really interested about why this is happening.
Your comment about trust is spot on. Any sort of swinging without a strong bond between the partners (including where they are married for reasons other than love/attraction to each other) would most likely end in divorce as the inner turmoil would eat at the couples feelings for each other. All types of people are involved in swinging including the shallow ego "Look at my Trophy Wife" types. Most in my experience are in it for mutual pleasure and guys who are only interested in sharing their wife without "swapping" are only a small portion. But no matter what combination MFMF, MMF MFF or variations thereon, all are first and foremost looking to light up their sex life and share in new erotic experiences. unless they are into BDSM it is unlikely they are out to upset or humiliate their partner, they truly want to give them pleasure and their partner loves them more for it. As the expression goes the guy typically wants his wife to be a little bit of a "Lady on the street and a freak in the bed". But in my experience Most find it strengthens their bond so your comment about divorce really only applies to couples who would have broken up anyway, are involved for the wrong reasons or lose focus on the reason they are involved in the scene and lose their love/bond with their partner.
