Well, I have been blacked for over 16 years now and I still fuck a black cock at least once a week if not more than that.
My husband started by bringing back home lot of interracial videos which we used to watch together and often he would by porn magazines showing well hung black studs with white ladys and eventually I started to fantasize about having sex with black men.
After about 6 months,my husband took me for dinner and drink in one of London's hotels where I had few drinks and he had arranged previously with a well hung black escort to meet us at the bar without telling me about it.The guy approached me when my husband was in the toilet and he was very handsome,tall,muscled black guy that triggered my sexual desires immediately.When hubby was back I introduced him to Peter,the black guy and after few drinks he asked me for a dance and I could feel his huge cock under his trouser which made my pussy so wet.Later my husband decided that all three of us go to our room which he rented without my knowledge and once there,he asked me to undress in order for Peter to give me a massage and during the massage,this black guy knew where to touch me and how to arouse me so I ended letting him fuck me while my husband was watching and since then I love to fuck black men.

Maybe you should break her in with a white bull it's not the color it's how you use it.

I bet it sucks to watch another man fuck your wife silly.

funny thing
 

...it's not easy to convince a wife (speaking as one) as it goes against our upbringing, church, etc. Having said that, the good thing is, once she has a taste of it you will not ever have to convince her again.

fantasysport's wife
 

Susu's husband knew how to get her done as she can attest to. That is the best way. I'm a long dong bull and I've picked up a couple of real hot married gals that way it works and the hubbys enjoyed watching me bang the hell out of the wife. Thats the way to get your wife down guys if she is balking at doing it.

I still suggest "evolving" accidently on purpose with a small white dildo up to two big black dildos with lots of suggestive talk while she is cumming .."suck that black man's cock honey,take his load,take that black cock deep in your pussy,black man is about to cum inside you....you're in training for the real thing baby so suck it good" then tell her how suprised you were at how much it turned you on to see a big black cock in her pussy sliding in and out...and how much she seemed to enjoy it...then a few pictures on craigslist and you are off and running.don't get her drunk or she may feel violated plus she won't appreciate every thrust and spurt..afterall the idea is for the husband to feel violated and for the wife feel a little tingle in her pussy and wetness and stiff nipples everytime she shakes a big black guys hand while glancing over to you with that "can I fuck this one?" look...

damn wanda thats hot

no luck here too
 

For years I've tried but all get is a big no. I may try the drinks in lounge when we go to Vegas in December

Took me about 6-7 years to persuade my wife, and that doesn't seem an unusual period from what I've read. Biggest issues were convincing her I didn't want to fuck other women, and that I'd still love her if she went with another guy. We then watched a lot of interracial porn, and talked about her being with a black guy when we made love - after some years she sort of connected orgasms with fantasies of well hung black men as I fucked her. To move it from fantasy to reality was tough, but I simply told her that it was very important for me, and that I needed it desperately. When she finally agreed to give it one try, we went on the web, found a guy on a swinging site and only 3-4 days later we were in an hotel room as a black guy fucked her in front of me. After he left I cuddled her, made love to her and told her how much I loved her. Took me all those years to get her to open her legs for another guy, and now she does it without even batting an eyelid - overcome her fears, and you're well on the way - good luck!

Any luck with the wife? I have got my wife to do it and she loves. Her daghter likes BBC like your step daughter and started before mother
