It's called cuckquean. Cuckquean is when a women who watches and allows her husband to have sex with other women sometimes in front of her. Sometimes the woman the husband is sexing with forces the wife to eat her out. The wife gets off on knowing her husband is digging out another chick. I personally believe this a bit more common but women are a lot less likely to admit to enjoying it or telling anyone if they are in a cuckquean lifestyle. Especially since a lot of women are more willing to do a FMF threesome than most men would do a MFM threesome with their significant other. I think women who let their husbands cheat as long as they come back home to them are cuckqueans in denial.
I think Cuckolding and cuckquean are for bi and lesbian/gay folk in denial.
I knew this chick who let her current husband fukk her best friend(skinny trailer trash white chick) in her bedroom while she waited in the living room. When they were briefly split back when they were just boyfriend/girlfriend, The girl fukked 3 dudes the week she was single and her husband told her he had to fukk her best friend if she wanted him bakk and that dumb hoe said yes. He was the most awkward ass dude I ever met, looked hella nerdy like Harry Potter and he was not rich so no one knew what the hell she saw in him. She was a decent blonde white girl. My cousin and his wife back when they were only BF & GF offered to do a threesome with her and she was down so I guess its whatever. This was all out in the boonies so I don't know if this was just ignorant redneck shyt or typical stuff.
Wild shyt. You would be SURPRISED how many fukked up sex stories I've heard and know about from family, friends, internet folks, acquantances IRL. All I have to say is that he world is a lot more sexually bizarre than we let on.
