What is it about BBC that makes us crave for it?

Curious cuck wannabe fantasize about sharing my woman with BBC only. The bigger and more aggressive the more it makes me wanna submit as well. I use to fantasize of sharing her and participating before. But after so long of fantasizing and watching cuckolding porn ive realized that i would never compare and accepted my role of just watching. Anybody else's fetish with black cock expand or progress to other kinks?
 
My wife likes the sheer size and the mentality of the BBC Lover! The animalistic rude fucking no love making just passionate hard thrusting strokes and nearly violent treatment while fucking. She always say :“you make love he just fucks me like a whore“
 
For me it is the fact besides the size it is the fact of how an experienced black man knows how to take me to my limits, and almost all of them are open to taking my husband as well. After years of swinging with anyone and everyone we met I came to realize black men were always my desire and preference, so much so that today we only invite open mature black men into our bedroom, my choice and my well hung husband accepts my desires.
 
As a cuckold shared my wife few times with bbc. They are much more bigger, better stamina, and they fuck really hard. My wife was really afraid from them even now she has a bit second thoughts but when she under them its another level of sex for her. No matter what your wife tells you she always wants big fat huge thick cock of a bbc.
